-Keep it concise. Write elegant code that reuses existing code and standard SDKs as far as possible, and avoid redundant code. Expose nothing that does not need to be exposed: no port, route, command or setting without a caller.
+### Simplicity and performance
+
+Do not multiply entities without necessity. The long-term goal is minimal code, dependencies and runtime overhead while preserving protocol correctness, isolation and clear ownership.
+
+- Before adding an abstraction, package, dependency, service, execution path or setting, show why existing code and maintained standard SDKs cannot meet a current requirement cleanly. Prefer reuse, simplification and deletion; do not build extension points for hypothetical needs. Expose no port, route, command or setting without a caller.
+- Keep cohesive responsibilities together and remove redundant layers and indirection. Split code at a real responsibility or protocol boundary, not to meet a file-size target. Fewer files or packages alone do not establish simplicity.
+- Justify performance optimizations with reproducible measurements against a baseline under representative workloads. Compare the relevant latency, throughput, allocations, memory use, startup time or distribution size, and account for added complexity and resource costs. Keep the simplest implementation that meets the measured requirement.

Core's reason for a rejection, or an uncertain-outcome warning, appears in red inside the dialog. The Skill page's delete dialogs follow the same grammar; deleting a whole Skill also requires typing its name. Archiving a project says in bold that it can't be undone, then how many active keys it revokes (the project read's count, or more when its loaded key list shows more) and that assets and accepted work stay; with active keys it too requires typing the project's name, shown in mono with its inner spaces kept (surrounding spaces are forgiven, Unicode compared in NFC).

 - **How to call**: wherever a new key is shown, a card under it gives three copyable samples, each a Margin Gray block with a Hairline and its label and copy button in a header row: a Shell block exporting `OPENAI_BASE_URL` (the installation's API base URL) and `OPENAI_API_KEY` (the new key) together, then curl and Python (with the pinned SDK), each listing the project's Agents and creating a Session with a first message (`environment`, an inline `agent` with `model: "<model>"`, and `input`). A copy the clipboard refuses selects the sample and says so in red underneath. One Graphite line says to put a model the model provider serves in place of `<model>`, and that running an Agent needs a model provider: in each request, saved on the Agent, or the deployment default. An active project's page shows the same samples as a section without any key: the Shell block exports a quoted placeholder, and a Graphite line above the samples says to use a key issued for this project, shown only once at issuance. When the public address is loopback, a note above the samples says the API is reachable only on the Core machine; without a public address only a note to set one shows.

Failed refreshes and project reads also raise an error toast; other failed actions, Core's clear refusal of a sandbox change among them, are reported there with the reason. A refusal leaves the page usable as it was. Errors inside a dialog or a form stay beside what they concern. Coverage notes (Margin Gray, Hairline ring, 8px corners, 12.5px Graphite) state bounded aggregation. Standing warnings that need action use an amber-tinted line at the top of the page body.

The stage is the product's one authored moment: a flickering indigo dot grid under slow light rays (Magic UI's flickering grid and light rays), Core as the OpenAgentCore mark on a tile with a travelling border beam, and two orbits of Agents, Sessions, Skills, Vaults, files, templates and machines around it; the OpenAgentCore mark is itself nodes on a ring. Brand copy sits bottom-left in solid ink; it is a paragraph, not a heading, because the panel's title names the task. Signing in asks for one thing, the deployment's Core key, in a single password field; the default key location and a copyable read command stay visible beneath it, with a reminder to substitute a custom installation directory. The key’s authority stays in a help tip. A refused key, too many attempts or an unavailable console is an error beside the field. Signing in opens the console on the Overview. The optional tour has three chapters — Monitor, Resources, Platform — whose stage shows a real dark screenshot of those pages, tilted towards the panel; it takes the place of the console until its last button, Skip or Escape, and then returns the focus to the control that opened it. Entering the console or the tour, and leaving the tour, happen inside a View Transition: the old page dissolves forward and the new one is revealed in a circle growing from the pressed button. With reduced motion the orbits hold their places, the grid is a still frame and no transition runs.

 ### Getting started
 The first card on the Overview while any step is to do: a card header ("Getting started", "n of 4 done", a help tip, then a ghost Take the tour button and an icon button that hides it) over four rows split by Faint Rules. Each row has a 22px numbered ring (a check on the tile wash when done), a 13px/600 title over one 12.5px Graphite line, a status dot (Done in green, To do in Pencil, Checking pending, Unknown for a failed read) and one outline action while the step is to do: Set up sandboxes, Add node, Open Nodes or Open sandbox backend; Open System; Create project (which continues to the new project's first key) or Issue key; See how to call (the newest active project, preferring one with an active key), or Projects and keys without an active project. Add node, Create project and Issue key open their page with the dialog already open; Open System brings the Default model provider section to the top of the page body and focuses the default harness's Set or Replace; See how to call opens the project and, once its keys, usage and address are read, brings its How to call heading to the top of the page body, focused. Only the page body scrolls; the page header stays. Every step done turns it into one line, "You're set", with Take the tour and Dismiss; it stays, through the tour, until dismissed, and the checklist does not come back on its own. The choice is kept per installation in the browser, also while the deployment cannot be read; Show Getting started, a quiet row above the sidebar's account controls, opens it again at any time.
 
 ### Sandbox setup
-Setting up hosted sandboxes is a set of pages inside System’s Sandbox configuration secondary page, one decision each: where sandboxes run (own machines or E2B), then the backend or the E2B account, then the size of each sandbox (three presets; E2B skips it, since each sandbox takes the template build's size), then a review. Choices are large cards that advance on a click; short indigo dashes show the progress; pages slide and blur across. The backend page compares microsandbox and Docker behind a help tip; microsandbox comes first, preselected (a saved backend stays selected), with a neutral Recommended pill beside its title. Docker takes a confirmation (see Dialogs) once per visit to setup; a saved Docker deployment has already made it. The review states where sandboxes run, the size, the Runtime (taken from this console's distribution manifest) and the Core address, read-only: it is config.json's `public_url`, and the console never asks for it. A loopback address carries an amber line under it: only the Core machine reaches it. When Core rejects the configuration for it (E2B with a loopback `public_url`), a red-tinted block under the review keeps Core's message and adds the config file and apply command as copyable values. A save attempt clears the transient E2B key. Initial setup then asks for it again, with a link to that step; an update may leave it blank to keep the committed key. Advanced settings, one link away, hold the complete form: resources (not for E2B), the Runtime release and the E2B template. A change keeps the saved size and Runtime while the backend stays the same (a saved size outside the presets is offered as Current). Same-backend editing starts at size or E2B credentials with the provider fixed. It is an online configuration update, including when older sandboxes remain: existing node identities and resource ownership are retained. Changing the backend or E2B team requires reset and then a new setup. E2B updates can omit the key to retain it; every explicitly entered key takes the verified replacement path and advances the target generation on success, including the same value. Rejections remain inline with a safe reason and a deliberate way back to reset; never infer teams from a key, auto-reset or auto-resubmit. Optional explanations sit behind help tips; errors and safety consequences remain visible.

 ### Configuration generations
 A single rollout row opens a details dialog for Core's target generation, previous-generation sandboxes and rollout counts. Poll rapidly only while Core reports preparing, or while the independent reset is active. Settled is preparation state, not proof that all nodes are ready or all older Sessions have ended. Retained old resources alone must not keep rapid polling alive. Render failed, update-required and unknown target states distinctly. Keep offline/live-provider status separate from a node's durable serving-generation pin; the pin alone never means the node is online or ready. Node detail shows the serving generation and target preparation; allocation detail shows the owned configuration generation. Do not calculate rollout completion from these rows or promise immediate placement on the target.

 Read deployment progress independently of node details. Partial failures retain successful facts with a visible stale/unavailable notice. An uncertain write opens the recovery dialog and requires a new authoritative read before another mutation; refresh reads state and never resubmits the write. The connection's QueryClient owns both the authoritative deployment and pending or uncertain writes across route transitions. Leaving Sandbox configuration cannot cancel or forget a submitted reset, and a cached node snapshot cannot replace a newer reset or completion learned on Overview. Returning to Nodes or Sandbox configuration reads the shared deployment immediately and refreshes node evidence separately. Only a successful authoritative read begun after the write settles can release the mutation block; an earlier or still-pending read cannot. Submitting consumes the reset confirmation even if its outcome is uncertain; recovery uses the separate read-and-review dialog. Observation retries preserve applicable non-secret configuration drafts. A changed installation, owner epoch, backend, mode or generation discards the prior draft and confirmation. Logout clears this connection-scoped state.

 ### One place for each task
 A configuration or operation has one home. Other pages link to it instead of repeating the same panel. System links to the Sandbox configuration secondary page; Nodes contains node management. Keep the configuration page flat: the resource editor is a dialog, and rollout is one status row with a details action. Put low-frequency counts and generation metadata in that dialog. Explanatory prose belongs in help tips, not rows of small print. Keep actionable errors and unresolved state visible without duplicating the whole workflow.

Cancel stops further clearing without undoing archives. Core alone reports progress and completion, including resources blocked on named offline nodes; force does not bypass their cleanup. Completion clears the backend configuration and retires old nodes/enrollment credentials. A new configuration is then a separate deliberate save.

Deletion follows the public deletion rules; a busy Session is not deletable and the console never cancels work to make it so.
 - **Secrets stay write-only.** Credential tokens, Template environment variables and setup commands are never returned, to the administrator included. An Agent's saved model provider shows its protocol, base URL, limits and whether a key is configured, never the key.
-- **Creators.** Core records the key behind every write. The console shows the creating key of each asset and a project's write history; an asset Core records as an administrator copy (`admin_copy`) shows as Admin copy and an asset without a record as Unknown.
+- **Creators.** Core records the key behind every write. The console shows the creating key of each asset and a project's write history; an asset without a record shows as Unknown.
 - **Waiting for results.** Overview, Session log and Session details name the function whose result the calling application must submit. The console cannot submit that result; environment connection waits stay distinct from function waits.
 - **Session history is read-only.** A Session page reads the Session, its Items and Turns and polls while work is in flight; there is no live event stream.
 - **Failure diagnostics.** Failed Session and Turn rows read Core diagnostics and translate its classified reason. The console never infers a cause from raw logs. Unavailable or mismatched diagnostics offer an explicit read retry; refreshing does not replay execution. Trace Timing keeps each Item's Core receipt interval separate from public Turn times and native tool duration. Historical missing timestamps stay unknown, negative clock intervals stay missing, and bounded response truncation remains visible.

 - **Connect a host.** The Linux/macOS and PowerShell commands come from Core's installation read for the Session's environment; the console shows them as they are, with a link to the native installation guide, and never builds one itself. A command downloads the matching installer, installs the chosen Harnesses, starts the daemon and checks its connection. Its authorization expires after 30 minutes; the console reads a fresh one every 20 minutes, and says the command is unavailable when Core has none. No model readiness is implied. Rotating a credential requires stopping the installed daemon, replacing the configured file and starting that same daemon again. A disconnected daemon may still be running; `start` alone does not replace it.
 - **Typed write errors.** Known Core codes use shared bilingual copy and safe typed details. Exact Core field paths attach definite refusals to the relevant input. Unknown codes retain Core's fallback message; uncertain write outcomes stay form-level and are never retried automatically.
 - **Read failures.** Overview and Session log distinguish unavailable reads from successful empty results. Failed reads have a visible retry; retained or partial data says it may be incomplete or out of date, and Session filter totals stay missing while any required read has failed. Only successful empty reads show zero.
-- **Local-only address.** Overview, Nodes and System warn when Core reports `local_only`, with the configuration path and apply command Core supplies as copyable instructions. Without a configuration snapshot they state what is missing. Add node is unavailable with a reason; Getting started keeps the first step to do until the public address is fixed. An unread installation address cannot complete that step, and a failed read offers Retry.
+- **Local-only address.** Overview, Nodes and System warn when Core reports `local_only` and lead to System to review the public address. Add node is unavailable with a reason; Getting started keeps the first step to do until the public address is fixed. An unread installation address cannot complete that step, and a failed read offers Retry.
 - **Figures.** Project, Agent and key usage comes from Core's summary; Agent run, tool and activity figures are still assembled in the browser from bounded reads and state their coverage. Metrics that would need new Core endpoints are not simulated. Usage is cumulative per Session and is not billing.
 - Runtime CPU and memory exist only for Core-managed hosted sandboxes.
 - Preserve workflow safety: confirmed deletion, no automatic retry of uncertain writes, no secrets in browser storage.

-# Standard sandbox sizes
-
-`standard-sizes.json` is the single source of truth for the default Standard size of each sandbox on a self-hosted backend. The console setup wizard offers it as Standard and derives Small (half) and Large (double) from it.
-
-## Structure and units
-
-```json
-{
-  "docker": { "cpus": 2, "memory_mib": 2048 },
-  "microsandbox": { "cpus": 2, "memory_mib": 4096, "root_disk_mib": 8192, "environment_disk_mib": 8192 }
-}
-```
-
-- `cpus`: whole CPUs, a positive integer.
-- `memory_mib`, `root_disk_mib`, `environment_disk_mib`: MiB, positive integers.
-- `docker` has exactly `cpus` and `memory_mib`; it has no disk fields.
-- `microsandbox` has exactly all four fields.
-
-The values must stay within the bounds that Core and `validSandboxResources` accept.
-
-## Readers
-
-The Web setup wizard is the only reader, through `defaultSandboxResources` in `deployment-specification.ts`. `deployment-specification.test.ts` pins the structure so that an accidental change fails.

+## Workspace storage
+
+Operator scripts use `GET /core/v1/workspace-storage` and `PUT /core/v1/workspace-storage` with a Core key. Web has no workspace storage editor. The request and successful response use the canonical filesystem configuration: `{"id":"<canonical UUID>","adapter":"<adapter identifier>","parameters":{...}}`. `parameters` is an adapter-owned JSON object; the selected adapter validates it. Unknown top-level fields are rejected.
+
+GET returns the selected configuration, or 404 `workspace_storage_not_found` when none is configured. PUT validates and selects an immutable configuration and returns it with 200. Reusing an ID requires identical adapter configuration; changing its meaning or conflicting with retained ownership returns 409 `workspace_storage_conflict`. Configuration changes are serialized with workspace ownership changes, and successful mutations carry the same administrator audit provenance as other deployment settings. The [workspace filesystem protocol](../../docs/workspace-provider.md) owns identity, attachment, admission and retention semantics.
+
+Invalid configuration returns 400 `invalid_workspace_configuration`; unsupported adapters or combinations return 400 `workspace_operation_unsupported`. Unavailable storage or an unconfirmed operation returns 503 `workspace_storage_unavailable`. Error messages do not expose native paths or adapter error text. The endpoint configures storage independently of Sandbox Provider selection; it does not create or delete a Session workspace.

 A **Harness** is a native agent engine (Codex, Claude Code, MiniMax Code) that runs the model and tool loop. A **Harness adapter** translates the Runtime's Executor and Turn contract into that engine's SDK or protocol. This document is the Runtime–Harness protocol: the adapter interfaces and their lifecycle obligations, registration, Core qualification and acceptance. [Harness capabilities](./harness-capabilities.md) records what each current Harness supports.

 Each adapter's `contracts.go` holds an individual compile-time assertion for each small interface. Do not embed a default implementation that makes future interfaces appear implemented. Adding a contract also requires a classification in the common completeness check and an explicit assertion in every public adapter; the check follows the authored Harness catalog.

 **Binding.** The Runtime binds its Executor record to the Session, Environment, connection and immutable execution configuration. Resume identity and prior-Turn recovery flags are continuity assertions, not configuration changes. A supplied native identity must match the retained owner, and when existing history is required, recovery never starts a new root. A configuration conflict is an error, not a hot switch. A lost connection retires its owners and handles; old timers, output and cancellation cannot affect their replacements.
 
-**Per-Turn state.** Each Turn gets a fresh wrapper, output channel and receipt state. Steering, function, permission and user-choice interfaces belong to that Turn. Native callbacks capture the originating Turn before asynchronous work, so a late event is never attributed to whichever Turn is active. Native processes, query or transport connections, fixed capability configuration and native session identity belong to the Executor. Do not reset completed `sync.Once` values or reuse an old Turn object.

Native processes, query or transport connections, fixed capability configuration and native session identity belong to the Executor. Do not reset completed `sync.Once` values or reuse an old Turn object.
 
 **Start.** A nil Turn from `StartTurn` guarantees that no native input was submitted and the output channel was not retained; the Runtime then closes the channel. Once input may have been submitted, return a non-nil Turn even with an error: that Turn owns exactly-once output closure and stays tracked until settlement. Unknown input is never replayed. A definite `executor_unavailable` Start rejection allows one common recovery attempt, only after the previous Executor has been closed and no input was submitted; the Runtime rechecks the same physical peer and the current authorization.
 
-**Cancellation and settlement.** `Turn.Cancel` targets only that Turn and does not close a healthy Executor. `AwaitSettlement` applies after both natural completion and cancellation. Success means output can no longer be written and the Turn's native events, input, functions, interactions and child work have settled. Native completion or cancellation confirmation is independent of resource retirement: closing a transport cannot supply a missing native terminal or operation receipt.

Native completion or cancellation confirmation is independent of resource retirement: closing a transport cannot supply a missing native terminal or operation receipt.
 
 - `Reusable=true` also confirms that the native owner can accept the next Turn. `Reusable=false` requires a reason and a later confirmed Executor close.
 - An error means settlement is unconfirmed and frees neither ownership nor capacity. Caller deadlines stop the wait, not the tracked cleanup. Retry the same cleanup target serially; a failed cleanup blocks replacement and keeps its resource slot.
 - `Executor.Close` confirms resource retirement independently of the Turn outcome: an immutable Turn error must not prevent closing the native transport once its work and output have stopped.
 - Include owned background work in settlement and keep the exact native cleanup target after a failure. Native termination belongs to the adapter; a bulk cleanup acknowledgement alone does not establish quiescence.
-- Every `Session`, including a direct-call factory result, declares `CancellationOutcome`. `Turn` and `PreparedCancellation` inherit it. The snapshot keeps observed native identity, Usage and output and remains readable after cancellation. Missing evidence stays unset; an empty `DonePayload` means nothing has been observed, not that cancellation succeeded or is unsupported. Reading the snapshot does not wait for settlement.
-- Direct-call `Session.Cancel` requests cancellation; output closure signals teardown. Executable `PreparedCancellation.Cancel` waits for local cleanup and output writes to stop. Turn settlement still requires `AwaitSettlement` and any required `Executor.Close`; neither a successful cancellation request nor its snapshot replaces those waits.

-**What the Runtime does around a Turn.** One output consumer starts before native Start, drains the bounded 64-frame channel and keeps the terminal observation until Start publication, Turn settlement and admitted operation receipts finish. Natural completion never calls Cancel. Input, function and interaction admission close before settlement; operations already admitted hold their barrier through native receipts and outbound acknowledgement. The Runtime sends cancellation to the Turn before waiting on that barrier, because a written input may need a native interrupt to produce its receipt. It joins native settlement, any required confirmed Executor close, output drain and all admitted operations before an applied acknowledgement or reuse, and only then forwards Done or an applied cancellation receipt. A failed Close can report failure while keeping the same Run and outstanding operations for retry; a closed caller wait cannot manufacture an applied input receipt. The Runtime commits native continuity and releases the old Run's admission before publishing Done, since the receiver may start another Turn at once; a late terminal-send failure belongs to the old Run and cannot invalidate a successor that already owns the Executor. Connection shutdown owns transport-loss cleanup. The settlement wait is ten seconds and the receipt send budget five seconds; a timeout is not proof of quiescence.

 ## Events, inputs and optional capabilities
 
 Use [`internal/agentdaemon/proto`](https://github.com/MiniMax-AI/OpenAgentCore/tree/main/internal/agentdaemon/proto) for neutral requests, events and receipts. Each Turn emits only its own events with its Run ID, in order, and one terminal outcome. Native IDs and usage are observed, never invented; a missing measurement is unknown, not zero.
 
-Initial input and steering use ordered `proto.MessageInput`. Keep user-message and content order. Text-only adapters reject images through `TextOnly()` instead of dropping them; image adapters translate each part natively and acknowledge an active batch only after all its messages are applied. A successful transport write is distinct from confirmed native application. User-choice answers use the emitted question ID and an array of values; the shared `PromptForUserChoiceDecisionPayload.AnswersFor` validates identity before consuming a pending interaction, so never map answers by header or position. Resume only the exact history bound to the Session; missing, ambiguous or foreign history fails before new model input. Device identity is not native session ownership.

It verifies that discovery retained the declared kind and registers the Runtime in this order:
 
 | Order | Method | Registers |
 | --- | --- | --- |
-| 1 | `RegisterKind(proto.SupportedAgentKind, harnessconfig.Configuration, agent.Factory)` | Kind, availability, version, `AgentKindCapabilities`, the model configuration declaration and the direct-call factory. It resets the other registrations, so call it first. |
+| 1 | `RegisterKind(proto.SupportedAgentKind, harnessconfig.Configuration)` | Kind, availability, version, `AgentKindCapabilities` and the model configuration declaration. It resets the other registrations, so call it first. |
 | 2 | `RegisterExecutor(kind, agent.ExecutorFactory)` | The Executor and Turn lifecycle used for execution; derives the `Preparation` capability |
-| 3 | `RegisterPreparation(kind, workspaceRead, agent.PreparationFactory)` | Optional: separate read-only workspace preparation for qualified workspace operations |
-
-The direct-call `agent.Factory` delegates to the same Executor implementation.
 
 Every `proto.AgentKindCapabilities` field must be explicitly `proto.CapabilitySupported` or `proto.CapabilityUnsupported`, even for an unavailable Harness. `proto.CapabilityUnspecified` is invalid: zero values and omitted fields never mean Unsupported. An installation probe may set an individual field with `proto.CapabilityFromBool`; it must not populate unmentioned or future fields. Availability stays separate in `SupportedAgentKind.Available`. Registration validates the complete declaration before changing the registry, and the wire carries an explicit boolean for every field, so omitted and null fields are invalid. A new field requires a decision in every production declaration. Runtime consumers use `IsSupported()` and reject unsupported requests before native operations; an interface assertion verifies implementation, never support. Every declaration must match the behavior verified for that installation; the [Core–Runtime protocol](../../docs/runtime-protocol.md#capability-declarations) owns how declarations travel and are frozen.

Verify initial execution, a warm follow-up, cancellation and restart with continuation; record native owner identity and same-condition cold and warm timing. For workspace placements also verify Files and Artifacts, workspace identity, that no credentials appear in public responses and that foreign history is rejected. `services/core/tests/official_hosted_functions_native.py` holds the shared function assertions: success and error, native file output and public Artifact bytes, same-history continuation after restart, foreign result rejection and pending-call cancellation. Synthetic or failed runs never count. The opt-in tests below run the pinned-SDK fixtures in `services/core/tests` against a real daemon and model; each runs when `OAC_TEST_OFFICIAL_SDK_PYTHON`, `OAC_TEST_NATIVE_DAEMON_BIN`, `OAC_TEST_NATIVE_PROOF_DIR` and its private options file are set. The options file is a JSON object with exactly `model` and `model_provider` (the fields of `x_agents_core.model_provider`); the test sets it as the deployment default model provider, which the fixtures' `environment: none` Sessions freeze at creation.
 4. **Regression.** Existing Harnesses keep working. Run targeted tests, then `make check`; run `make openapi` after API changes and `make sqlc-generate` after query changes.

An internal reaper also cleans remaining group members when the direct process exits, even if a descendant still holds stdout open; during cancellation, surviving descendants keep the remaining grace after the leader exits. The daemon's `stop` command waits up to ten seconds for confirmed shutdown, which covers that grace period and the pipe and owner cleanup after it.
+The daemon's `clirunner` starts every native child in its own Unix process group (a Job object on Windows); other hosts reject the launch.

The daemon's `stop` command waits up to ten seconds for confirmed shutdown, which covers that grace period and the pipe and owner cleanup after it.
 
 Owned output pipes stay readable after the leader exits. Consumers drain stdout and stderr before calling `Wait`, which joins the cached process result and closes the readers. `Done` reports leader reaping and group cleanup signals; it is not a native execution receipt or proof of persisted history. SDK adapters settle each Turn and drain its observations before publishing completion, and Executor close also closes the query and awaits the native child. Process groups are lifecycle supervision, not isolation or containment of descendants that leave the group.

+Adapters run native tools unattended with the launching user's permissions, and a Harness never asks a human.

Claude runs through the adapter's tool callback, which allows or denies without asking, in native `default` permission mode with the SDK sandbox disabled. MiniMax runs with bypassed permissions and its sandbox disabled; the adapter disables `askUser`, advertises no elicitation and answers `session/request_permission` with the ACP `cancelled` outcome, which MiniMax treats as a denial.

-Contract tests hold Core to the pin: the router and `openapi.yaml` serve exactly the pinned routes (`services/core/internal/api/routing_test.go`, `v1/upstream_contract_test.go`), every query parameter and field is official, and Core-only fields sit only inside `x_agents_core` on Agents and Sessions. Swagger 2.0 cannot express string-or-array unions, so `openapi.yaml` leaves Session `input` and function-result `output` unconstrained; the pinned types and Core's validation define them. Operations and fields newer than the pin wait for a protocol upgrade.
+Run `make openapi` to regenerate the public Go types, the Agent request shapes, the route inventory and all three OpenAPI documents. `scripts/generate-public-api.py` reads the checked-in, checksum-verified official source without network access. It selects Agents, Vaults, Files and Skills and follows their schema references, preserving union types, nullability, required fields and constraints. The request shapes in `services/core/internal/api/official_shapes.gen.go` project `CreateAgentParams`, `UpdateAgentParams` and `SessionAgentConfigParam`; Core checks request bodies against them before it reads an Agent configuration. Core's extension types in `v1/` remain authored in Go and are added to the public schema during generation. The TypeScript client's types, enum values and field names in `packages/agents-client/src/generated/public-api.ts` are generated from the resulting public schema. The internal `/core/v1` and `/api/v1` documents come from handler annotations; the same generator projects the `/core/v1` document into `packages/agents-client/src/generated/core-api.ts`, which imports the public types it references from `public-api.ts`. In those annotations a response field Core always sends carries `binding:"required"`, a field that can be null carries `extensions:"x-nullable"`, and a Core-owned closed set uses a named Go type with typed constants in its producing package. Swag derives one enum definition from that type, shared by every wire field. Single-value discriminators keep `enums:` tags; fields mirroring official or Runtime-owned sets retain tags checked against their owners by contract tests. These annotations only shape the documents, and the client rejects a response that breaks them. `make check-openapi` checks freshness and the generator; it also runs through `make check-go`.
+
+The public contract is the official API plus Core extensions. Standard fields are generated into `v1/official.gen.go`; `go-bindings.json` lists types consumed by Core and overrides only the Go representation or field order that existing storage or custom JSON encoding requires. Unspecified fields follow the official schema; shared shapes use one Go type. Selected discriminated unions also generate JSON serializers to retain required nullable fields for each variant. Other union serializers, Core's local limits, execution admission and state transitions remain implementation code. Contract tests verify that the public schema preserves the official definitions, extensions remain in `x_agents_core`, and all documents match registered routes. Official-client and raw HTTP tests verify behavior. Schema generation does not qualify an unimplemented feature; the gaps below still apply. Upstream upgrades update the OpenAPI and SDK pins together after comparison and compatibility tests.
+
+The official source and existing service have these recorded differences: Agents authentication errors can return a null `code`; empty Files pages return null `first_id` and `last_id`; File resources can return null `expires_at` and `status_details`. The source declares those fields non-null. The official-client response validator allows null only for these named fields and otherwise validates OpenAPI 3.1 response schemas. Files and Skills operations omit error responses in the source, so those error bodies use the upstream shared `ErrorResponse` schema. [Wire semantics](./wire-semantics.md) and raw HTTP tests qualify service behavior; the published schema retains the official definitions.
+
+Go input projections exclude `packages.system` to preserve its explicit rejection, recorded below. Generation does not enable an unsupported operation or change stored setup validation.

All ten suspension operations belong to the same `SandboxProvider` and are declared supported or unsupported together; dispatch uses no optional interface. `Observe` reads one allocation per request.
+
+The current wire version is 7. Create bootstrap and Resume requests may carry an optional workspace filesystem binding. The node validates its tenant and Environment against the allocation reference, its immutable ObjectID, and its attachment configuration ID against the supplied configuration before forwarding it. The filesystem resolver validates adapter-native ownership. A missing binding selects owned storage; a present binding cannot fall back. Error responses may retain a Resume target only when its nonempty native ID, name, generation and retained-state provenance match the requested target; this is cleanup evidence, never successful restore.

-        returns 400 invalid_request_error, and several implicit matches return 409

-        fallback. Required initialization uses native startup before the first native
-        Turn, including cold resume, and requires a separately advertised capability;
-        exact hosted creation timing and error parity remain unverified. Explicit
-        environment-origin HTTP MCP is supported on managed and self-hosted workspaces
-        through the same Runtime bindings; native OAuth login remains unsupported.
-        The self_hosted profile uses a qualified native harness, a clean absolute
-        workspace_directory and optional absolute local capability_directories prepared
-        by Runtime, with optional non-deferred function tools and HTTP MCP using explicit
-        environment origin, optionally authenticated by the attached Vault rules.
-        Service-origin HTTP remains restricted to service-side environment:none. Remote
-        MCP and remote Bearer authentication each require separately advertised combination
-        support; old peers cannot receive unsupported work. Omitted/null capability_directories
-        use the empty-list default; self_hosted requires configured execution plus
-        executor registry. Claude SDK currently requires medium verbosity and object-root
-        function schemas. It supports anonymous or attached static-bearer service-origin
-        HTTP MCP on none with boolean required and separately advertised MCP/bearer/required
-        runtime support. Required servers must be connected before the first native
-        input is released; pending or failed startup rejects execution. The shared
-        Vault selection and immutable binding rules apply; unsupported native labels/tool
-        names reject before persistence. An attached Vault with no matching credential
-        may remain anonymous; missing keys or failed credential lookup/decryption
-        never fall back to anonymous execution. Omitted stream defaults to false;
-        stream and agent_id cannot be null. Metadata may be null; non-string values
-        and limit violations return invalid_request_error with a metadata or metadata.<key>
-        param. The inline agent uses the Agent create configuration validation with
-        agent.-prefixed params, reported before the input requirement and saved-Agent
-        lookup; saved configurations with conflicting tools or schema roots reject
-        admission with the same errors, and execution limits keep unsupported_or_invalid_configuration.
-        Hosted network policy rejections return invalid_request_error with a null
-        param. Initial input accepts a string or ordered user-message array. Codex
-        and Claude SDK on none and qualified managed or self_hosted workspace profiles
-        also accept inline PNG/JPEG image content; other image combinations and remote
-        URLs are unsupported. None initial input atomically starts a Turn; self_hosted
-        initial input is reserved while returning its Environment connection target,
-        with execution deferred to native readiness and Session failure on initial
-        timeout. Initial input is required for none and for streamed creation outside
-        self_hosted. Omitted/null input remains valid for non-streaming hosted and
-        self_hosted creation. With stream=true, returns live Session events starting
-        with the committed creation snapshot and closes right after the first agent.session.idle
-        recorded when a Turn ends or an input reservation stops being pending, or
-        any agent.session.failed, without sending later events. A creation that admitted
-        nothing closes after the snapshot; a settlement that records no event closes
-        after events up to the cursor read with a settled Session projection. Required
-        actions keep it open; disconnect does not cancel execution. The GET events
-        stream remains live-only. New Sessions retain their authenticated creator;
-        all creation retries require the same typed subject, including across key
-        rotation. Saved-Agent retries and inline requests using Vault attachments
-        or credential references retain caller intent independently of later resource
-        changes; new hosted inline requests also freeze caller intent before deployment
-        defaults resolve; unrelated non-hosted inline retries preserve resolved/default
-        equivalences, and their resolved hash leaves out any deployment default. Provider
-        keys enter retry hashes only as fingerprints keyed by the credential key.
-        Unknown historical creators reject retries; known creators without recorded
-        intent retain resolved-snapshot retry rules. These conflict policies are local
-        and not verified hosted parity. A same-key stream=true retry of an existing
-        creation returns 201 with no events and closes at once; retry with stream=false
-        or use the GET events stream to recover. Claude SDK on none, Core-managed
-        Docker openai_hosted and self_hosted supports qualified object-root json_schema
-        output with medium verbosity, single-Agent execution and ordinary functions.
-        Hosted execution reuses native workspace tools and Files/Artifacts; Skills,
-        Plugins, capability directories, HTTP MCP, Subagent and tool_search combinations
-        remain unqualified, including inherited template contents. Other non-text
-        initial input remains unsupported. Basic Codex and Claude SDK openai_hosted
-        creation requires an explicitly configured managed provider. The Claude workspace
-        profile supports non-deferred function tools with text or successful inline
-        PNG/JPEG results alongside native workspace tools; explicit environment-origin
-        HTTP MCP uses the common Runtime path. MiniMax accepts public environment-origin
-        HTTP MCP only with null or omitted allowed_tools and required=false; even
-        an empty non-null allowlist rejects. Idle Sessions provision automatically;
-        initial provisioning has no caller connection action. Network defaults to
-        enabled; disabled and restricted policies reject before compute allocation
-        because the current Runtime cannot enforce them. The x_agents_core.environment
-        extension accepts common preparation fields for either hosted or self-hosted
-        placement: environment_template_id, files, env, packages, setup_commands,
-        skills, plugins and capability_directories. Duplicate fields in environment
-        and the extension reject. Confidential env, npm/Python packages and ordered
-        setup commands use the same Environment-owned initialization lifecycle; compute
-        allocation does not own preparation. Unknown side effects are not replayed
-        after disconnect or restart. System dependencies must be preinstalled in the
-        sandbox image or template, or on the host machine; packages.system is rejected.
-        Initial inline and tenant-owned file_id files freeze encrypted bytes before
-        provisioning, then install through the common Core lifecycle before native
-        execution or live Files access. With a template reference, omitted/null files,
-        env, packages and setup_commands inherit. Non-null files and command lists
-        replace; env overlays by key; each package manager inherits on omission/null
-        and otherwise replaces its list. Empty lists clear their selected field. Tenant-owned
-        environment_template_id references inherit omitted/null network and allow
-        only narrowing overrides. Inline hosted network:null retains the enabled default;
-        updating a Template with network:null resets its saved policy to enabled.
-        Core freezes effective configuration; template updates/deletion do not alter
-        Session snapshots or same-intent creation retries. Inline or tenant-owned
-        skill_reference Skills share initialization. Templates preserve default/latest/explicit
-        selectors; Session creation freezes concrete metadata and encrypted content
-        atomically. Skill, Plugin and capability-directory list omission/null inherit;
-        a non-null list replaces, including empty-list clearing. Omitted/null Skill
-        version selectors resolve the default version. Source deletion/default updates
-        cannot change committed Session Skill contents. Deferred function discovery
-        uses type-only tool_search and per-function defer_loading in the qualified
-        single-agent Claude function profile on none or a managed/user-owned workspace,
-        including qualified inline image messages and text results. Explicit web_search
-        mode disabled and programmatic_tool_calling enabled false use frozen common
-        Runtime controls. Enabled forms, including those saved on an Agent, remain
-        unqualified and reject before any write unless the Session replaces tools.
-        Omitted programmatic configuration preserves native behavior, a documented
-        difference from the official default-on behavior. Other combinations remain
-        unqualified; see the operation coverage.'

-        Live-only events, including command output fragments from capable Codex peers as agent.output.command_execution_output.delta with stable Item/output indexes. Native text conversion and output quotas apply; completion snapshots remain authoritative. Reconnect through Session, Turn and Items reads; missed events are not replayed. A lagging stream closes with an error when its bounded buffer is exceeded. When a hosted Environment fails to provision, the stream sends agent.session.environment.failed, an error event (environment_error/sandbox_error with the safe step and exit-status reason, never command output) and agent.session.failed, then ends. Session activity includes immutable pending-input connection actions before Turn creation; self_hosted environments use the same safe output as Session retrieval.
-        Active streams revalidate the original Project key every second before output; revocation, Project archival or authentication unavailability closes the stream. Authentication checks use a five-second timeout.

-        none, atomically accepts text messages, cancellation and function results.
-        Messages steer active work or start a queued Turn. Qualified Codex and Claude
-        SDK workspace profiles accept text and inline PNG/JPEG messages, independently
-        of managed or self_hosted ownership. Under the Session lock, matching retries
-        retain their original target; new active messages append to the current Turn,
-        while idle messages reserve work and wait up to the original five-minute connection/admission
-        deadline. Return 202 only after durable admission, without claiming native
-        application; active messages create no Turn or reservation. Cancellation-only
-        prepared-environment batches use existing durable cancellation admission and
-        return 202 without waiting for native exit; a new cancellation conflicts while
-        a pre-Turn reservation is pending. Homogeneous tool_result-only prepared-environment
-        batches reuse existing scoped result admission and application receipts without
-        creating a Turn or bypassing a pending reservation. Mixed prepared-environment
-        batches remain unsupported. HTTP expiry/cancellation use local 409 environment_input_expired/environment_input_cancelled
-        errors. New input on a Session whose hosted Environment failed to provision
-        returns the observed 409 conflict_error "the hosted environment failed to
-        provision"; input already waiting when it fails and expired Environments keep
-        the local 409 environment_unavailable. Input the Session cannot accept in
-        its current state, such as a result after cancellation or a batch while earlier
-        input is pending, and a result that differs from the call's saved result return
-        409 with type and code conflict_error; reusing an Idempotency-Key with a different
-        batch returns the local 409 idempotency_conflict. Inside an owned Session,
-        a result for an unknown call or for a call of another Turn returns 400 invalid_request_error
-        and changes nothing; missing and foreign Sessions return 404. Losing execution
-        ownership returns 503. The response write deadline accommodates the admission
-        window for either prepared Environment, independently of new-hosted-admission
-        and executor URL settings. Disconnecting the waiting HTTP request does not
-        cancel retained work or restart its deadline. Retry keys identify the whole
-        ordered batch. Function output accepts text or ordered text/image parts subject
-        to engine support; Claude SDK accepts text results and, on none and qualified
-        workspace profiles, successful inline PNG/JPEG results, preserving ordered
-        content; error images and remote references reject before admission. Native
-        image resizing may change bytes. Runtime image-result support is checked only
-        for image-bearing delivery. Codex and Claude SDK on none and qualified managed
-        or self_hosted workspace profiles accept ordered inline PNG/JPEG image messages.
-        Other engines remain text-only; remote image URLs are unsupported. Image references
-        are retained unchanged without service-side downloads.

+The resolver (`services/core/internal/deployment/observation.go`) reads the Session, its Environment, the current allocation and the Session's measured usage from the database. A Session, daemon connection, process, container and native Harness Session are different identities and never stand in for one another.
 
 Managed Docker, microsandbox and E2B allocations are observed. `none` and `self_hosted` Sessions are `unsupported`; Core never attributes shared host statistics to an `environment:none` Session.
 
-The allocation's persisted `provider_key` selects exactly one configured source, which verifies the allocation's labels or equivalent ownership data before it returns values. Before any provider read, the allocation state decides some rows: `creating` or no allocation yet gives `allocation_pending`, `cleanup_pending` or `released` gives `runtime_not_running`, and a provider key without a source gives `source_not_configured`. A provider read that exceeds its deadline gives `sample_timeout`, a not-running result `runtime_not_running`, and an unavailable result `sample_unavailable`. Any other error, an ownership mismatch or an invalid sample fails the read.
+Every managed allocation is read through the deployment's selected Sandbox Provider, which verifies the allocation's installation (`provider_key`) and labels or equivalent ownership data before it returns values. Before any provider read, the allocation state decides some rows: `creating` or no allocation yet gives `allocation_pending`, and `cleanup_pending` or `released` gives `runtime_not_running`. A provider read that exceeds its deadline gives `sample_timeout`, a not-running result `runtime_not_running`, and an unavailable result `sample_unavailable`. Any other error, an ownership mismatch or an invalid sample fails the read.
 
-The observation boundary is declared in `services/core/internal/runtimeobs/source.go`. Each registered `SourceResolver` declares supported `ResolveObservationSource`; registration validates this declaration without loading configuration or reading the database. Core resolves each provider key once per page, then validates the returned `Source` and uses that same immutable source for every read of the key on that page. An unconfigured resolver returns typed `ErrUnavailable`, which produces `sample_unavailable` without a provider type. Other resolution errors follow the provider-read error rules above.
+`Observe` belongs to the [Sandbox Provider protocol](../../docs/sandbox-provider.md); `services/core/internal/runtimeobs/source.go` owns the observation types and the `Source` view of a Provider. Core loads the selected Provider and its registered kind once per page and uses that same immutable Provider for every read on that page, reading each running target with `Observe`. Without a selection the load returns typed `ErrUnavailable`, which produces `sample_unavailable` without a provider type. Other load errors follow the provider-read error rules above.
 
-A source declares supported `ObservationProviderType`, which returns its immutable telemetry identity: a lowercase letter followed by at most 31 lowercase letters, digits or underscores. Empty identities are invalid. Provider registration and every resolved binding validate the identity and operation declarations before any sample or export. Reconfiguration affects later source resolutions; it cannot change the identity or provider selected for an in-flight page. Generation routers continue to resolve each allocation through its recorded deployment generation.
-
-A source implements `Observe` and declares `ObserveBatch` in its provider operations. When `ObserveBatch` is declared supported, one call reads up to 100 targets of that provider; when it is declared unsupported, Core reads each target with `Observe`. A failed batch read is never retried target by target. The [Sandbox Provider guide](../../docs/sandbox-provider.md) describes the operation declarations.
+An observation's provider type is that registered kind: `docker`, `microsandbox` or `e2b`.

 ### Periodic sampling
 
-Periodic collection runs only with the execution worker (Core started with `OAC_PUBLIC_URL`; see the [Core environment](../../docs/configuration.md#appendix-core-environment-without-the-installer)) and under the worker's database lease. A Core without it stores no history and answers every history read with 503; current reads work on either.
+Periodic collection runs in the execution Worker, under its database lease.
 
 The sampler sweeps once at startup and again each sampling interval after the previous sweep ends. A sweep is a keyset scan, in Session ID order, of the Sessions that are not deleted, are `openai_hosted` and have no released allocation. It reads pages of 32 Sessions through the same resolver and sources as current reads, with eight concurrent reads and two seconds per source. The sampler checks the lease before each page and every 100 ms during a sweep, cancels in-flight reads when ownership is lost, and checks it again before handing each record to export. A failed row does not stop the sweep, and an incomplete sweep is repeated at the next interval.
 
-Every observation, current or periodic, is marked with its collection source, `on_read` or `periodic`, and handed to each exporter's bounded queue. A full queue drops the record, which becomes a missing sample, never a zero. The PostgreSQL history store and the optional OTLP exporter have independent queues, so an exporter outage cannot delay local history or execution. The [`core.runtime_history` settings](../../docs/configuration.md#settings) set the interval, queue capacity, timeout and OTLP destination.

+The optional response `specification.workspace` is an immutable capability receipt derived from the selected [workspace filesystem](../../docs/workspace-provider.md), not an independently writable setting. It contains only `attachment`, `user_xattr` and `capacity_quota`; filesystem configuration, paths and credentials stay outside the sandbox specification. Core validates the combined declarations before saving, and retained generation validation and node construction use this receipt. Missing `workspace` preserves owned disk mode, including its existing disk bounds. Create and Resume must provide a binding exactly when the frozen generation selects external storage.
+
+To enable external storage for an existing owned deployment, select the filesystem configuration first, then update the sandbox deployment with compatible resources (`environment_disk_mib: 0` for a filesystem without quotas). Selecting the filesystem does not alter existing generations or allocations. The next sandbox update derives the external receipt; old owned allocations keep their owned disks. A filesystem selection must support the provider's declared requirements, and an already external deployment requires an equivalent declaration with compatible quota semantics.

The `metadata` field is a good way to disambiguate\nmultiple simultaneous Responses.\n\nClients can set `conversation` to `none` to create a Response that does not write to the default\nConversation. Arbitrary input can be provided with the `input` field, which is an array accepting\nraw Items and references to existing Items.\n",

Input that cannot be committed is returned in\n`response.steer.failed`.\n\nSteering may cause the active response to finish at a safe output boundary\nwith `response.incomplete` and `incomplete_details.reason` set to `steered`,\nfollowed automatically by a successor `response.created`. Normal completion\ncan also be followed by an automatic successor. Automatic successors inherit\nthe previous response's settings and continue from it with the queued input.\n\nIf the response stops for client-owned tool output or approval, accepted\nsteering input remains queued and `response.steer.pending` is emitted after\n`response.completed`. Fill the `required_input` stubs from that event with\nsaved tool results or approval decisions, and send one explicit\n`response.create` per parent with the same `previous_response_id` and\nWebSocket lane. Do not rerun tools or resend accepted steering input. The\nqueued input is prepended in submission order to that request's input, and\nthe explicit request retains its own settings.\n\nThis event accepts only `type`, `previous_response_id`, and `input`. Do not\nsend `stream_id`; the target response determines the WebSocket lane.\n",

+An unreadable or malformed key file stops Core at startup. Losing or replacing the key makes every stored secret unusable. Reads, lists, deletion, Vault operations, new Credentials and `static_bearer` token replacements still work; an `mcp_oauth` update returns 500 `internal_error`, and a dispatch that needs an old secret fails. A saved E2B key is lost too, so hosted Sessions return 503 `execution_unavailable` until you open **System** → **Manage sandbox configuration**, choose **Reset deployment** (with **Force — cancel remaining work now** if needed) and set up the backend again; sandboxes left behind expire under their E2B timeout. Core supports one key, with no rotation or re-encryption.
 
 ## Deletion
 
-Deleting a Credential, or its Vault, removes the credential rows. It does not erase secrets from PostgreSQL pages, write-ahead logs, backups or native history. Afterwards its reads, updates and repeated deletion return 404, lists omit it, new Sessions cannot select it and new Credentials cannot be created in a deleted Vault (a missing storage key still answers 503 first).

Afterwards its reads, updates and repeated deletion return 404, lists omit it, new Sessions cannot select it and new Credentials cannot be created in a deleted Vault.
 
 Existing Sessions keep their frozen attachments and selections, and their history stays readable. The next dispatch that needs a deleted Credential fails; Core neither selects another Credential nor connects anonymously. Deletion does not cancel running work, withdraw a token already sent to a Runtime or revoke the grant at its provider: cancel the Session and revoke the grant yourself when needed. Revoked or invalid OAuth grants likewise fail until replaced.

+运行 `make openapi` 重新生成公共 Go 类型、Agent 请求结构、路由清单和三个 OpenAPI 文档。`scripts/generate-public-api.py` 读取仓库内经过校验和验证的官方源文件，无需网络。它选择 Agents、Vaults、Files 和 Skills，并跟随 schema 引用，保留联合类型、可空性、必填字段和约束。`services/core/internal/api/official_shapes.gen.go` 中的请求结构投影 `CreateAgentParams`、`UpdateAgentParams` 和 `SessionAgentConfigParam`；Core 在读取 Agent 配置前先按它们检查请求体。Core 在 `v1/` 中的扩展类型继续由 Go 定义，在生成时加入公共 schema。TypeScript 客户端在 `packages/agents-client/src/generated/public-api.ts` 中的类型、枚举值和字段名由生成后的公共 schema 生成。内部 `/core/v1` 和 `/api/v1` 文档由处理函数注解生成；同一生成器把 `/core/v1` 文档投影为 `packages/agents-client/src/generated/core-api.ts`，其中引用的公共类型从 `public-api.ts` 导入。在这些注解里，Core 总会发送的响应字段带 `binding:"required"`，可以为 null 的字段带 `extensions:"x-nullable"`，Core 拥有的封闭集合使用生产方包中的具名 Go 类型和带类型的常量。Swag 从该类型生成一个枚举定义，供所有线上字段共享。单值判别字段保留 `enums:` 标签；映射官方或 Runtime 所有集合的字段保留标签，并通过契约测试与其所有者核对。这些注解只影响文档，客户端会拒绝不符合它们的响应。`make check-openapi` 检查生成结果是否最新并测试生成器；`make check-go` 也会运行此检查。
+
+公共契约是官方 API 加上 Core 扩展。标准字段生成到 `v1/official.gen.go`；`go-bindings.json` 只列出 Core 使用的类型，仅在已有存储或自定义 JSON 编码需要时覆盖 Go 表示或字段顺序。未覆盖的字段遵循官方 schema，相同结构复用同一个 Go 类型。部分带判别字段的联合类型也从 schema 生成 JSON 序列化代码，保留每个分支必需的可空字段。其他联合类型序列化、Core 的本地限制、执行准入和状态转换仍由实现代码负责。契约测试验证公共 schema 保留官方定义、扩展位于 `x_agents_core` 中，且所有文档与注册路由一致。官方客户端和原始 HTTP 测试验证行为。生成 schema 不代表某个尚未实现的功能已经得到验证；下方缺口仍然适用。升级上游时，在比对和兼容性测试后一起更新 OpenAPI 和 SDK 固定版本。
+
+官方源文件与已有服务存在以下已记录的差异：Agents 鉴权错误的 `code` 可以为 null；Files 空页的 `first_id` 和 `last_id` 为 null；File 资源的 `expires_at` 和 `status_details` 可以为 null。源文件将这些字段声明为非空。官方客户端响应验证器只对这些指定字段允许 null，其余部分按 OpenAPI 3.1 响应 schema 验证。源文件中的 Files 和 Skills 操作未声明错误响应，因此这些错误体使用上游共享的 `ErrorResponse` schema。[传输语义](wire-semantics.md)和原始 HTTP 测试验证服务行为；发布的 schema 保留官方定义。
+
+Go 输入投影排除 `packages.system`，保留下方记录的明确拒绝行为。生成过程不会启用尚未支持的操作，也不会改变已存储安装配置的验证。
 
-契约测试确保 Core 符合固定版本：路由器和 `openapi.yaml` 提供的路由与固定版本完全一致（`services/core/internal/api/routing_test.go`、`v1/upstream_contract_test.go`），每个查询参数和字段都采用官方定义，而 Core 专有字段仅位于 Agents 和 Sessions 内部的 `x_agents_core` 中。Swagger 2.0 无法表达字符串或数组联合类型，因此 `openapi.yaml` 不对 Session 的 `input` 和函数结果的 `output` 施加约束；这些类型由固定版本的类型定义和 Core 的校验逻辑确定。晚于该固定版本的操作和字段需等待协议升级。

 每个 Session 都运行一个 Harness，并使用一个模型提供商。Core 通过三个固定版本上游协议未定义的 Core 扩展来选择它们：`x_agents_core.harness` 选择 Harness，`x_agents_core.model_provider` 提供端点和密钥，`x_agents_core.harness_config` 携带原生模型参数。Core 没有提供商目录、模型别名解析或产品权限模型；除 Session 和已保存 Agent 配置包外，唯一存储的配置包是每个 Harness 的一个 [deployment default](#deployment-defaults)。本文档定义 Harness—模型提供商协议：[`internal/modelprovider/config.go`](https://github.com/MiniMax-AI/OpenAgentCore/blob/main/internal/modelprovider/config.go) 负责验证冻结的提供商连接，每个 Harness 则通过 [`internal/harnessconfig/harness.go`](https://github.com/MiniMax-AI/OpenAgentCore/blob/main/internal/harnessconfig/harness.go) 声明其协议和原生参数。

 ## Installation
 
-`install.sh` downloads its release's `compose.yaml`, checks it against `compose-sha256sums.txt`, writes `.env`, and starts Compose. Core applies database migrations when it starts. The host needs Linux amd64 and Docker Compose 2.26 or newer. [Configuration](../docs/configuration.md) owns the installation layout and settings.
+`install.sh` and `install.ps1` select a native `oac` release binary, verify its checksum and invoke `oac install`. That Go command owns the same installation lifecycle on Linux, macOS and Windows: validate Docker, verify release configuration, prepare `.env` and the host command, pull images, publish the installation directory, initialize the data volume and start Compose. [Installation](../docs/getting-started/install.md#prerequisites) owns platform prerequisites; [Configuration](../docs/configuration.md) owns settings and storage.
 
-`oac` is a Go command (`services/core/cmd/oac`) in the Core image and the ingress image. The host copy implements `apply`, `core-key` and `rotate-core-key`; `core-key --show` runs `oac-web core-key` in the Web container. Start, stop, logs and removal are `docker compose`. `apply` runs `oac-core check-config` before recreating services. The ingress image runs data initialization as `oac init`, verifies and copies its bundled node metadata without network access, and contains no Python. No service receives a Docker socket.
+Preparation happens in `<install-dir>.staging`. On entry, the installer removes an empty stage or one with the empty ownership directory `.oac-installer-<hash of the installation path>`; it preserves unrecognized directories. Ordinary failures remove owned staging immediately. The ownership marker is created atomically before downloading files. A killed process leaves staging for the next attempt. Publication happens only after downloads, checks and pulls succeed. Later failures preserve saved configuration, containers and the Docker data volume. Retries reuse those settings and cached images, pull missing images and start services with `--pull never --no-recreate`. `<install-dir>.lock` is a persistent lock directory shared by installation and mutating operator commands; the existing `runtimefs` platform adapter owns locking.
+
+The host `oac` command also implements `apply`, `core-key` and `rotate-core-key`. `apply` checks Core configuration before recreating services. Reading the key executes `oac-web core-key` in Web. Rotation runs in the initialization container, where Linux file ownership is identical on every host, then restarts Core and Web. Start, stop, logs and removal use `docker compose`. The initialization image verifies and copies bundled node metadata without network access. Its receipt authenticates immutable metadata and credentials; the operator-rotatable Core key and its digest remain mutable. No service receives a Docker socket. Initialization emits structured step logs without credential values; view them with `docker compose logs --timestamps init`.
 
 Web serves the console and forwards `/v1` and `/api/v1` to Core, so it is the only published service. HTTPS is terminated by the operator's reverse proxy or hosting platform, which routes to `web:8080`; `OAC_PUBLIC_URL` records that origin.

 ## Download contract
 
+The generated command uses `~/.oac/node-bootstrap` in the invoking account's home. Under `download.lock`, it discards an unfinished `download.partial`, downloads and verifies the bootstrap, then publishes `<sha256>.pyz`. The lock is released before invoking sudo; verified files stay available to running installers. Node file writes share `distribution.temporary_file`: under the caller's installation lock, remove the previous temporary file, write privately, and publish atomically. The same lifecycle covers payloads, extraction, helpers, settings and enrollment tokens. Registration tokens are removed even when a rerun finds the node already registered.
+
+Configuration files are published only after their complete contents are written; a retry preserves an existing matching file and refuses conflicting contents. Generation leases are durable locks, not disposable temporary files: interruption between creating a lease and recording its inode identity requires operator inspection. A retry refuses that unrecorded lease instead of replacing an inode that a Runtime helper could still hold.
+
 The distribution manifest is the one download contract for nodes: flat versioned file names, and the compressed and unpacked size and SHA-256 of the Runtime.
 
 - A Compose installation keeps only the node metadata from its release archive; Core's image never acquires execution-only payloads.
 - A node obtains bootstrap metadata from the console that generated its command. Web serves artifacts it has locally and redirects missing declared execution artifacts to the versioned HTTPS release base in the verified manifest. Web never downloads or caches those bytes.
 - Only artifact requests may follow HTTPS redirects, and only without credentials or cookies. Metadata and enrollment requests stay on the configured console. The console publishes only fixed non-secret files and declared artifact names.
-- Download into private temporary files, verify size and SHA-256 before an atomic rename, resume interrupted transfers, and reuse only verified cache entries or exact image identities. Never select a release other than the pinned one.
+- Download into private temporary files, verify size and SHA-256 before an atomic rename, clear leftover temporary downloads and extracted files before retrying, and reuse only verified cache entries or exact image identities. Never select a release other than the pinned one.
 - Release downloads are anonymous. Never add repository credentials to installed node or Runtime configuration.
 - Manual builds use the `build-<full SHA>` release tag and tag builds the `v*` tag. The manifest's download base must match the release tag; artifact file names and source provenance keep the full source SHA.

 After the daemon connects, Core checks the available Harness and requested capabilities. The Runtime prepares a workspace Environment and its capability snapshot, then prepares or reuses the Session Executor. Each Turn runs through the native Harness. Core persists the output, tool interactions and receipts for application reads and events. Completion or cancellation settles the Turn; a healthy Executor can serve the next Turn in the same Environment.

 Set `OAC_SANDBOX_MAX_ACTIVE` and `OAC_SANDBOX_MAX_RETAINED` in `.env`, then run `oac apply`. Core uses these limits for direct Providers with suspension enabled. Every unreleased allocation consumes retained capacity. Lowering a limit stops no existing sandbox; new allocations wait until usage falls below both limits. These settings are independent of `OAC_EXECUTION_CONCURRENCY` and enrolled node capacity.
 
+### Independent workspace storage
+
+The initial supported independent filesystem combination is microsandbox with the [kernel NFS adapter](./workspace-provider.md#kernel-nfs-adapter). Mount the same NFSv4.2 export on the Linux Core host and every participating node before starting their services, at the same absolute path, for example `/srv/oac-workspaces`. The operator manages the export, mount availability and service startup ordering. Use a trusted-client AUTH_SYS export with `root_squash`; do not enable `no_root_squash` or broaden permissions to make a check pass. Prepare the namespace and service principals according to the adapter's [ownership requirements](./workspace-provider.md#kernel-nfs-adapter).
+
+Core's Compose service already runs as UID 65532. Before adding a node, prepare `oac-node` with the same UID, home `/var/lib/oac-node`, a nologin shell and a nonzero primary group. Its supplementary groups may contain only its primary group, `docker` and `kvm`; an existing home must belong to that account. The installer adopts this account. Without a precreated account it allocates a system UID, which need not match Core. Resolve an existing UID or account conflict as a host administration task before enrollment; changing a running account's UID is not part of storage setup.
+
+For a Compose deployment, add a read-write bind mount to the existing `core` service's `volumes` through the deployment platform's Compose customization. Keep the existing service volumes and user unchanged. The host source must already be the NFS mount; `create_host_path: false` prevents creating a missing source directory but does not establish that NFS is mounted. Mount before creating the container; after a host unmount or remount, recreate it so its mount namespace uses the intended mount.
+
+```yaml
+services:
+  core:
+    volumes:
+      - type: bind
+        source: /srv/oac-workspaces
+        target: /srv/oac-workspaces
+        read_only: false
+        bind:
+          create_host_path: false
+```
+
+Select storage using `PUT /core/v1/workspace-storage` with the Core key as described in the [administration API](../contracts/agents-api/admin-api.md#workspace-storage). Generate separate canonical UUIDs for the immutable configuration `id` and the namespace marker, then submit this shape with your actual values:
+
+```json
+{
+  "id": "11111111-1111-4111-8111-111111111111",
+  "adapter": "nfs",

+    "uid": 65532
+  }
+}
+```
+
+Then create or update the microsandbox deployment through the [sandbox deployment API](../contracts/agents-api/sandbox-deployment.md#routes), setting `resources.environment_disk_mib` to `0` and retaining the required compute resources, Runtime and provider configuration. A positive value requests a quota that this adapter does not enforce and is rejected. Deployment workspace requirements and each Session's attachment are derived from the selected database configuration; do not add a filesystem field to the deployment or a second storage configuration to node files. Web has no workspace storage editor.
+
 ### Node capacity
 
 Core approves a node's capacity when you generate its Add node command: **Sandboxes at once** (`max_active`, default 2) and, for microsandbox only, **Retained sandboxes** (`max_retained`, default 8), with `max_retained >= max_active >= 1`. Docker never suspends sandboxes, so Web doesn't ask for it and Core keeps `max_retained` equal to `max_active`. Change them later with **Edit node**. Reservations and cleanup that is not confirmed count against capacity; lowering a limit stops no running sandbox. A node's own files can't change its capacity, size or Runtime.

 ## Configure the public address {#configure-the-domain-and-https}
 
 Applications, nodes and sandboxes reach Core at one address, the public URL. HTTP is enough on the local network. When you expose Core beyond it, put a reverse proxy in front and set the public URL to the HTTPS origin it serves. E2B guests reach Core from the internet, so they need a public URL that is not loopback.

 A node reports only its first failed check, in this order: the Docker daemon or KVM, Docker's limit support, host capacity, then the installed Runtime files.

 ## Runtime startup latency
 
-Inline pairing validates Harness discovery before consuming its one-shot token and reuses that result. For other connections, after local credentials and enrollment are resolved, Runtime Harness discovery and the authenticated bootstrap HTTP request run concurrently. Both must succeed before the Runtime opens its connection or publishes capabilities. Failure cancels the sibling operation and waits for its cleanup. Reconnect and suspension retain their existing lifecycle; concurrency does not skip executable or credential validation.

 The daemon logs `executor preparation stage` with `stage=workspace`, the executor and Session IDs, duration in milliseconds and `success`. Codex logs `codex preparation stage` for `session_plan`, `model_catalog`, `process_spawn`, `rpc_initialize` and `verification`, with the owner trace, duration and `success`. These records contain no native error text, credentials, configuration, catalog contents or command output. An omitted conditional stage is unobserved, not zero. `session_plan` contains `model_catalog`; the executor readiness interval contains workspace preparation, the adapter stages and transport overhead. Do not add nested intervals together. A failed `rpc_initialize` includes its required child cleanup.
 
 Within `model_catalog`, `model_catalog_command` includes the original native command, exit and pipe draining; `model_catalog_cleanup` measures the existing best-effort process-group signal only when a process was started. Its `success` reports the signal return value, so an already-exited group can report false; it does not prove descendants were reaped and does not change the command outcome. `model_catalog_validation` covers JSON/model/verbosity and managed-home validation; `model_catalog_snapshot` covers snapshot creation, write, close and attachment to the Session plan.

 | `Docker Compose 2.26 or newer is required` | Update the Docker Compose plugin |
-| `The services did not start: …` | A new installation's first start failed, and the installer [removed what it created](./install.md#install). Compose's or Core's error is printed above it; fix the cause and run the same command again |
-| `Removal did not finish. Left: …` | A failed first start could not remove everything. Run the printed commands to remove what is left, or fix the cause and run the same command again |

 ### Container registry
 
-Version releases and manual `build-<full SHA>` drafts publish Linux amd64 images as `ghcr.io/minimax-ai/openagentcore/<component>:<version>`, where `<component>` is `core`, `web`, `runtime` or `ingress`. For example, `ghcr.io/minimax-ai/openagentcore/core:v1.2.3`. A draft uses the tag `build-<full SHA>`. PostgreSQL uses its upstream image and is not republished. The registry images are loaded from the release archives without rebuilding. Existing version tags are reused only when their image config digest matches the release; a different image stops publication. A stable release also moves each component's `latest` tag to that image. Prereleases and drafts leave `latest` unchanged. SemVer build metadata uses `_` in place of `+` in container tags; version strings longer than 128 characters cannot be published to GHCR. After the images are verified, the publisher uploads the single `compose.yaml` and its checksum list, rendered for that release. Compose pins the ingress image by its registry digest; initialization rejects an image whose build revision differs from the Compose revision. A draft Release stays unpublished.
+Version releases and manual `build-<full SHA>` drafts publish `ghcr.io/minimax-ai/openagentcore/<component>:<version>`, where `<component>` is `core`, `web`, `runtime` or `ingress`. Core, Web and ingress indexes contain Linux amd64 and arm64 images; Runtime contains Linux amd64. Platform images use `<version>-<architecture>` tags and are loaded from the release archives. Existing version tags must match the release images and platform set. The publisher verifies every version index before updating `latest` for a stable release; prereleases and drafts leave `latest` unchanged. PostgreSQL uses its upstream image. SemVer build metadata uses `_` in place of `+` in container tags; version strings are limited to 128 characters. After verifying the images, the publisher uploads the release's `compose.yaml` and checksum list. Compose pins ingress by its index digest, and initialization checks its build revision against the Compose revision.
 
 The combined build/publication job uses `GITHUB_TOKEN` with `packages: write`. On the first publication, GitHub creates each container package as private: a package administrator must change all four packages to **Public** in their package settings before users can pull anonymously. See [GitHub container visibility](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry). Verify an unauthenticated pull after changing visibility. Repository visibility alone does not make a new container package public.
 
 GHCR and GitHub Releases do not share a transaction. A failed release may leave some matching version tags in GHCR; preserve those images and follow the draft recovery procedure below using the original artifacts. Registry failures other than a missing manifest stop publication. The job summary records digest-pinned references. These images and the rendered Compose files still require the configuration, secrets and routing described in [Configuration](./configuration.md).

 Go check and build jobs share Go module and compiler-cache directories under `~/.oac/cache/`, keyed by runner OS and architecture, all Go module files, the check/build partition and the commit. Partitioned keys prevent concurrent jobs from saving different compiler subsets under one key. Release builds can seed their cache from backend checks as well as earlier release builds. An older cache only seeds downloads and compilation; every check still runs. Release jobs also cache npm package downloads and the pinned microsandbox archive, whose checksum is verified on every build. Actions cache visibility follows GitHub ref scoping; a tag-specific cache is not shared with other release tags. New keys are saved only after a successful job.

Its header shows green for no findings, red for findings, and yellow for an incomplete review without findings. Only this notification job receives the webhook secrets. Failed, missing or invalid reports appear as incomplete, alongside any available result from the other review. The notification job runs even when a review fails.

 Measure completed runs with `python3 scripts/ci_metrics.py RUN_ID ...`. It reports the latest attempt's summed runner minutes, elapsed time and initial queue delay from that attempt's start, peak concurrent jobs, platform breakdown and job outcomes/failure fraction. Only jobs assigned a runner in that attempt contribute machine time and execution concurrency; jobs cancelled while queued retain their outcome and wall time. Earlier attempts are not included. Failed-job reruns can carry earlier successful results: their outcomes appear separately and their old execution time is excluded.

The error names the exact operation and a safe code, never a native message, resource identity, endpoint or credential. An empty result, a nil error, `Unavailable` or an unknown mutation outcome never stands in for unsupported, and the five required methods can never return it.

-`ObserveBatch` returns an error, not an ambiguous boolean.

+`sandbox/providers/registry.go` is the only registration table.

There is no init-time registration or plugin loading.
 
 A new provider takes these steps:
 
 1. Implement the operation contracts in the adapter package, with native contract tests.
-2. Add its specification and resource validators and, for native resource discovery before commit, an optional read-only `SelectionDiscoverer`. Put native credential verification behind `CredentialVerifier`.
-3. Implement `sandbox.ConfigurationAdapter` over a typed native configuration. `DecodeInput` strictly parses the separate public `configuration` and write-only `credential` objects of a request. `Encode` produces whitelisted public selectors, read-only observations and separate secret bytes, and never passes request JSON through. `Decode` restores stored selectors, and keeps access to owned resources, without remote admission or new template validation. `Normalize` copies its input before changing it. `ResolveChange`, `Equal` and `WithCredential` own inheritance, identity and credential composition. `Requirements` declares whether a credential and a public Core origin are required and whether configuration discovery is supported. Also implement `ConfigurationDiscoverer`, even when discovery is unsupported: it validates the query and returns a safe catalog, never a mutation or an admission decision, while Core keeps authorization, input limits and deadlines. A node provider accepts only an empty public object, rejects credentials and returns Unsupported for discovery and credential replacement.
-4. Register its constructor, policies, configuration adapter, operation declaration and defaults in `providers/registry.go`. Node proxy identity and suspension support read this entry. The installer's projection combines the registered policies with the shared field bounds in `sandbox/deployment_contract.go`; regenerate it with `go run ./services/core/cmd/specification-contract -write`.

Both receive the candidate's `sandbox.DirectConfig` and build any native client for that call only. A node provider accepts only an empty public object, rejects credentials and returns Unsupported for every setup operation and for credential replacement.
+4. For a node adapter, export from its package the `BuildLocal` constructor, the typed `native` object it decodes and the native files it adds to the shared node artifacts. Node-local settings, such as host paths, live only in that object; resources and the Runtime release are read from the node configuration's `specification`.
+5. Register its constructor, policies, configuration adapter and operation declaration in `providers/registry.go`. Its key is the provider kind, which also labels the Provider's observations, and suspension support reads this entry. The generated projections combine each registered mode and deployment policy with the shared field bounds in `sandbox/deployment_contract.go`: the installer reads them from `deploy/node/node_spec.py`, and the TypeScript client and Web from `packages/agents-client/src/deployment-contract.ts`, so Web reads these declarations instead of comparing provider kinds. Regenerate both with `go run ./services/core/cmd/specification-contract -write`.

-- Suspension support requires positive idle and retention defaults that fit Runtime durations in either direct or node mode; a provider without suspension support configures no suspension defaults.
+- Suspension is admitted in both `nodes` and `direct` modes when the complete lifecycle is declared supported. A registration carries no suspension values: Core applies its one [suspension policy](#suspension) to every supported Provider.

Every `ConfigurationRequirements` field needs an explicit valid decision: `Credential` and `PublicOrigin` are `Required` or `NotRequired`, and `Discovery` uses the shared supported or unsupported declaration with a safe reason. A new requirement field or discovery method needs an explicit validation update and never inherits an existing decision. Configuration discovery is distinct from resource selection discovery, and requiring a credential does not promise the `VerifyCredential` operation. These checks establish complete registration, not correct native SDK behavior; constructor and adapter contract tests still apply.

 ### Configuration storage and construction
 
-Preview and persistence use `providers.Normalize` and `providers.Describe`. `SelectionDiscoverer` resolves omitted native values before commit, and the complete specification is validated again at persistence. `providers.ResolveChange` owns configuration inheritance, and comparisons use normalized selectors, so preview, retry and commit share the same defaults. The store owns transactions, credential encryption, generation fencing, resource ownership and generic object storage: only the adapter interprets `provider_config` and `provider_metadata`, and `provider_credential` holds ciphertext bound to the installation and generation. Retained generations keep their original public configuration and metadata and compose the current credential through the adapter, so a credential replacement never rewrites a retained selector. Database constraints check object structure, not the registration list.

 A direct adapter with a credential verifies all retained generations and allocation references before a key is replaced. The common `sandbox.CallFence` excludes native calls and waits for helper completion, including calls whose callers timed out; execution invokes the prepared verification and fencing callbacks without branching on a vendor.
 
-Vendor deployment validation and SDK setup stay at the construction boundary, and construction never creates an Environment. For node-local adapters `providers.Built` returns the provider, probe, installation identity, backend fingerprint and specification digest, and the factory also returns its close function. `execution.RuntimeProvider` binds the adapter to its kind, installation ID, backend fingerprint, generation, mode and node ownership; the database owns the selection, and the in-memory copy is never another authority. Docker and microsandbox run on nodes, and E2B is constructed directly. The node proxy exposes suspension operations only for a backend whose registered declaration supports them, and common lifecycle code admits suspension through `SuspensionProvider`, never through a provider name.

 The backend fingerprint identifies a native resource namespace, not capacity. Core keeps deployment generations so that owned allocations keep resolving to their original backend; never repoint retained allocations at a replacement backend.
 
 ### Distribution artifacts and process paths
 
-Each node adapter's registration owns its typed `NodeArtifacts` declaration: logical distribution path, release filename suffix and installation role (`node`, `runtime`, `policy` or `image`). Registration rejects missing declarations, unsafe paths and unknown roles. `go run ./services/core/cmd/provider-artifacts -write` generates the shared Web catalog and Python projection. Run the command without `-write` to check freshness. Distribution packaging, Web availability and node installation read this projection; adding a provider's payload does not add a provider-name branch to those consumers.

 At startup Core claims the stable installation identity and a new owner epoch before it selects a provider. The runtime manager keeps generation-aware provider facades. Initial setup and replacement prepare and validate candidates before any database write, and a rejected candidate leaves the active configuration and workers unchanged. A backend replacement uses the deployment mutation gate: it pauses manager admission, drains old calls and loops, then repeats the resource and generation guards in the commit transaction, where the new selection, its generation and the retirement of old nodes and unused enrollment tokens commit together. After commit, Core publishes the prevalidated configuration and the shared observation and bootstrap cache under the manager mutex, with no further external work or fallible step, so a request cancelled after commit cannot discard it. An interrupted drain stays a barrier for retries. Provider I/O and draining never hold a database transaction or the manager's map mutex.

+A locally unavailable provider dependency keeps hosted admission closed while the existing scan waits for repair; administrator recovery stays available, also after a restart.

Core derives the Runtime bootstrap and daemon WebSocket addresses from the installation public URL, never from request headers, and reads the current selection from the database, never from a startup file.
 
 Node readiness binds to the exact generation, the current connection and the owner epoch. A durable serving pin is promoted only for readiness of the then-current target, under deployment serialization, so a late report for a superseded target never acquires a pin.
 
 ### Allocation lifecycle
 
-Core includes the owning Session’s immutable Harness in `Bootstrap.Harness`; every provider projects it into the [Runtime bootstrap](./runtime-bootstrap.md) without choosing an implementation.
-
 The allocation, its dedicated daemon credential digest and the exact Session binding commit atomically before `Create`, under the execution lease and the Session lock. Only a fresh allocation receipt permits `Create`; retries and a Core restart observe the same reference without replaying it or rotating the credential. An allocation is private compute ownership, separate from public Environment connection and native readiness; adapters qualify bootstrap completion, and Core never infers it from an engine or provider name.
 
 With a configured provider, the Worker scans committed pending hosted Environments that have no allocation, which covers idle Session creation and recovery after an interruption between commit and bootstrap; an existing allocation never re-enters that path. The scan is bounded and serialized by the lifecycle owner and needs no caller action. An initial reservation without a Turn leaves its Session idle, and a daemon connection is never treated as native readiness. The same scan publishes authenticated connection observations with durable generations, after verifying the exact Session and device binding and a settled bootstrap.
 
-Connected, observed compute receives service keepalives between Turns. Keepalives never revive a lapse of one hour or a cleanup request. A node allocation never expires only because its keepalive is an hour old; explicit deletion and the snapshot retention still authorize its cleanup. A stopped or missing container never authorizes discarding retained workspace or history. Disabling the provider stops new hosted admission and bootstrap but never blocks cancellation, function results or input retry outcomes of existing Sessions.
+Between Turns, Core checks that connected, observed compute is still its Session's running allocation; the check changes nothing and never revives a cleanup request. Running compute never expires: explicit deletion and the retained-state retention authorize its cleanup. A stopped or missing container never authorizes discarding retained workspace or history. Disabling the provider stops new hosted admission and bootstrap but never blocks cancellation, function results or input retry outcomes of existing Sessions.
 
 Terminal cleanup atomically revokes the device's authority, records the Environment's failure or expiry, settles pending input and requests cancellation, and only then calls `Kill`; original input deadlines and retry outcomes are kept. Temporary provider outages, unknown Create results and stopped compute never prove a permanent failure. After public Session deletion Core keeps the allocation and marks it released only after owned compute and volume cleanup and proof that the original Create settled; an unknown creation keeps cleanup ownership even after an absence observation, and bounded scans continue to catch late resources without another `Create`.
 
 ### Per-node lifecycle workers
 
-Each registered node has one serial lifecycle worker that owns its gate, allocation and pending cursors, connections and wake hints; E2B allocations share one serial lifecycle without a node. A thin coordinator discovers nodes and shuts workers down, and never holds its map mutex during database, provider or wait operations. Workers advance independently, so a stuck provider on one online node never stalls another: lifecycle concurrency is one operation per node and grows with the node count. Offline workers stay, so their retained resources remain observable after reconnection.
+After a hosted Environment commits, Core sends a bounded hint to the lifecycle worker for its placement. Committed pending input also sends a hint to recover a missed creation notification. Hints reuse the serial gate, execution lease, capacity checks and one-shot allocation receipt; admission handlers never create a sandbox directly. Each normal maintenance period admits at most one extra hinted scan, and periodic scans recover missed or coalesced hints. Existing allocations are observed before pending provisioning, so a slow observation on the same node can still delay a fresh Environment.

 ### Suspension
 
-Core suspends an initialized Environment, including one with no Turns, when no root or Subagent Turn, input, file operation or initialization is pending and real activity has exceeded the deployment's idle duration. The shared database clock, Session lock and lifecycle lease serialize admission; heartbeats never reset idle activity. Queued work and live Files access request wake; history and published artifacts do not. The daemon drains native cleanup, receipts and file work before acknowledging quiescence. A lost acknowledgement authorizes only exact-source rollback, never a new capture.
+The single `SandboxProvider` contract declares `Initial`, `NewCompute`, `GetCompute`, `RenewCompute`, `Suspend`, `Resume`, `KillCompute`, `DeleteRetained`, `RunCommandCompute` and `ResumeCompute` together: all are supported or all are unsupported. No optional suspension interface or provider-name branch selects this lifecycle.
+
+`RetainedState` is an opaque adapter-owned envelope with `Reference`, `ID`, `Data`, `OperationID`, `SourceGeneration`, `SourceName` and `SourceID`. `Data` is nonempty and at most 64 KiB. Core preserves the envelope unchanged and validates operation and source ownership; the immutable allocation provider/generation binding selects the only adapter allowed to interpret it. A retained state need not be an independent snapshot. Microsandbox retains its complete native snapshot identity in `Data`; E2B retains its versioned native pause receipt and cannot promise a separate disk image. Each adapter validates its native payload and ownership before any effect.
+
+`Compute.RestoredFrom`, `ComputeState.Retained`, `ResourcesReleased`, `SuspendSettled` and recovery's `ReconcileOnly` are authoritative settlement evidence. A missing resource is not proof that an unknown suspension settled. `RenewCompute` renews only the exact incarnation; an uncertain result never authorizes a second create, capture or restore. Durable `runtime_compute` uses `protocol_version: "1"`; startup rejects missing or unknown versions. Existing version-1 retained envelopes remain readable without a rewrite. Snapshot-only durable shapes are not implicitly converted, and deployment never performs synthetic replay or discards retained state.
+
+`ResumeRequest.Workspace` carries the allocation's independently owned filesystem binding. Core obtains a ready binding before restore. Suspension must prove the source released active execution before a target can become a writer. Adapters validate the binding before native effects; an adapter without independent filesystem support rejects a non-null binding. `DeleteRetained` deletes only adapter-owned retained compute state, never the workspace. Explicit Session deletion first settles compute cleanup and then deletes independent storage, preserving a single active writer throughout recovery.
 
-The complete declared SuspensionProvider group uses one lifecycle for direct and node placements. A RetainedState is an allocation/source/operation-bound opaque adapter receipt, limited to 64 KiB of native Data; it does not claim a snapshot. Core never interprets native Data. Initial and NewCompute plan exact logical incarnations without allocating resources; native IDs may remain equal across logical generations. GetCompute only observes. RenewCompute extends the exact running incarnation without waking it; the common running path observes and renews before keeping ownership or clearing a wake.
 
-Suspend owns native resource release and returns a bound retained handle, suspended status, ResourcesReleased and SuspendSettled before Core releases active capacity. ReconcileOnly forbids replay of the original capture or pause while permitting adapter-owned cleanup proved safe by a durable retained artifact. A retained-less result permits rollback only with SuspendSettled and a recoverable running or paused source. Every other uncertain outcome retains ownership and closes admission. Core never unconditionally destroys the source after Suspend.
+Core suspends the idle work of every provider that declares suspension support, with one fixed policy: it suspends work idle for 5 minutes (300 seconds) and keeps retained state for 24 hours (86400 seconds). The deployment's [`suspension`](../contracts/agents-api/sandbox-deployment.md#safe-response) reports these values. Core suspends initialized Environments, including those with no Turn yet, when no root or Subagent Turn is queued, in progress or waiting, no input, file operation or initialization is pending, and real activity has been idle for that time. For allocations Core records initialization completion and root or child terminal transitions with the database clock in the same transaction. Candidate filtering and the Session-locked recheck compare elapsed database time with the idle duration, and the initial retained-state retention deadline is anchored to the same database observation, so Core and database host clocks need not agree. Native completion timestamps stay unchanged in public history but never drive idle admission, and heartbeats never reset activity. Before acknowledging a planned suspension, the daemon closes admission and drains native cleanup, output receipts and file work.
 
-Resume consumes the retained state into the precommitted target exactly once. Recovery observes the same attempt. Core persists waking, authenticates and resumes the daemon, deletes the consumed retained resource, then commits running and admits work. DeleteRetained is idempotent artifact cleanup and preserves running compute. Failed cleanup keeps the waking phase and cannot trigger another restore. KillCompute remains genuinely destructive; cleanup of an old generation must not kill a newer live incarnation sharing its native ID.
+The Worker lease, the Session lock and the per-node gates own suspension for every provider. New Turn claims, file-write intents and capture admission serialize under the Session lock and share one compute-phase check; new pending work cancels a capture and wakes the same source. Normal preparation waits for the compute phase to be running, after the authenticated resume handshake, and pending input stays pending when its promotion conflicts with a lifecycle transition. Compute phases and revision-checked receipts live on the allocation. Core persists quiesce, capture and restore intent before the effect, only a fresh receipt performs a capture or restore, and recovery observes the exact attempt without retrying an unknown creation, capture or restore. Consumed retained state never rolls a running generation back. Deletion, revocation and retention expiry win over wake, up to the final database compare-and-swap, and unknown cleanup identities are kept until owned resources are confirmed absent. Consumed artifacts and old compute are deleted, so suspension cycles never build a chain of writable disks.
 
-The existing Session lock, lifecycle lease, idle rule, capacity queries and cleanup order remain authoritative. Every unreleased allocation consumes max_retained, including running allocations. Every allocation is stamped with the shared compute protocol version at reservation, including allocations whose suspension phase is disabled. Activation refuses any unreleased allocation with a missing or different version; the previous release must complete ordinary cleanup before upgrading. Session history is preserved.
+Queued work and live Environment file access wake a suspended Environment; history and published Artifact reads do not. Planned suspension uses an Environment and suspension token on the daemon connection. A PID and start-time fenced local control signal (`RunCommandCompute`) wakes the parked daemon, which authenticates again before admitting work. A transient disconnect before confirmation retries the same armed suspension with bounded attempts and backoff; a permanent authentication or protocol rejection closes it. Core owns the retained state's retention deadline, and the daemon has no timer for it. A lost quiesce acknowledgement may thaw the same source through explicit rollback but never authorizes capturing it.
+
+`Suspend` owns native resource release. Core releases active capacity only after receiving a bound retained handle, suspended state, `ResourcesReleased` and `SuspendSettled`. `ReconcileOnly` prohibits replaying the original capture or pause but permits adapter cleanup justified by durable retained evidence. An outcome without retained state permits rollback only with `SuspendSettled` and an exact source that can resume; other uncertainty retains ownership and closes admission. Core never unconditionally destroys the source after `Suspend`.
+
+`Resume` consumes retained state once into the precommitted target. Recovery observes that same attempt. Core persists `waking`, authenticates and resumes the daemon, deletes consumed retained resources, then commits `running` and admits work. `DeleteRetained` is idempotent cleanup that preserves running compute. Cleanup failure keeps `waking` and cannot trigger another restore. `KillCompute` remains destructive; old-generation cleanup must not kill a newer active incarnation sharing its native ID. Every unreleased allocation, including a running one, consumes `max_retained`. Every reservation records the shared compute protocol version, including allocations whose compute phase is `disabled`. Activation rejects an unreleased allocation with a missing or different version; the old version must complete its normal cleanup before upgrade. Session history remains.

 One snapshot and timestamp partition the held resources. Offline ownership comes from the allocation's or active placement's node, with the same 45-second connection and owner-epoch predicate as online presence, independently of provider readiness; no cleanup failure, offline state or empty read authorizes a synthetic release. At zero held resources, Core drains outside database transactions, rechecks under the deployment lock and clears the deployment in one transaction, then publishes a generation-bearing empty provider without fallible work. If the final write or drain fails, it restores the committed provider with a bounded owner context before releasing the mutation gate; if that recovery fails, admission stays fenced and the owner stops.

+## Independent workspace attachment
+
+`Bootstrap.Workspace` and `ResumeRequest.Workspace` optionally carry a [workspace filesystem binding](workspace-provider.md). Absence selects the Provider's owned Environment disk; presence selects the exact external object and never permits a fallback to an owned disk. Providers validate the tenant and Environment against the binding and its configuration receipt before resolving it. `LocalOptions.Workspace` injects the filesystem resolver; Sandbox Providers never interpret filesystem adapter parameters or native receipts.
+
+`DeploymentPolicy.Workspace` declares supported attachment requirements; absence means external storage is unsupported. The derived immutable `DeploymentSpec.Workspace` receipt selects the generation mode and capabilities; its [deployment workflow](../contracts/agents-api/sandbox-deployment.md#resources) never copies filesystem configuration into the generation. Microsandbox requires `host_directory` and `user_xattr`; Docker and E2B reject external attachments. `ValidateWorkspacePolicy` uses the filesystem protocol's combination validator: an external filesystem without an enforced quota rejects a positive `EnvironmentDiskMiB`, while zero requests no quota. Root disk capacity is still required. Without an external declaration, the existing owned disk bounds apply.
+
+Microsandbox resolves each Create and Resume binding, including observation of an interrupted restore, and passes only the local directory and immutable ObjectID to its private helper. The helper binds the whole `/environment`, including workspace, staging, initialization and packages; private HOME and Harness history remain in the VM's checkpointed root. Explicit mode, object and path labels qualify native resources; mount shape alone never selects a mode. Restore verifies the snapshot's object, remaps `/environment` through SDK `Volumes`, requires strict external mount policy and rejects every restore warning. Partial restore errors retain the exact target identity for cleanup and never establish readiness. Unknown outcomes remain observations of the original operation. Native Bind checkpoint and guest-local flock continuity evidence does not establish cross-VM fencing.

+title: Workspace filesystem providers
+---
+
+The independent workspace filesystem boundary is defined in [`workspacefs.go`](https://github.com/MiniMax-AI/OpenAgentCore/blob/main/services/core/internal/workspacefs/workspacefs.go). This document specifies the required integration contract; it does not establish that every Sandbox Provider or placement implements it. Filesystem adapters own storage objects and native attachment resolution. [Sandbox Providers](sandbox-provider.md) own compute. Core selects and validates their combination before allocating either resource.
+
+## Identity and configuration
+
+`Reference` contains immutable, canonical lowercase, nonzero UUIDs for `TenantID`, `EnvironmentID` and `ObjectID`. Core persists the reference before creation. Object identities are never reused, including after deletion or an unconfirmed mutation. An adapter must verify the entire ownership tuple before exposing or deleting an object.
+
+`Configuration` is an immutable Core database record with its own canonical UUID `ID`, an `Adapter` identifier and adapter-owned JSON object `Parameters`. The database is its only authored home; changing configuration creates a new identity. Core forwards parameters without interpreting native paths. Existing objects remain bound to their original configuration.
+
+`Attachment` binds an adapter-issued JSON object `Native` to the complete reference, configuration ID and attachment kind. It is internal ownership evidence, not an application-provided host path. Shared validation checks the envelope and expected reference/configuration match; the selected adapter must also validate its parameters, receipt and native ownership. Structural validity alone never authorizes filesystem access. Public Session payloads must not supply attachments, configuration parameters or resolved host directories.
+
+`Binding` carries the configuration and attachment transiently to a node resolver. This transfer does not introduce a second persistent node configuration. `Resolver.Resolve` validates the binding and returns `Directory{Path}` for the local compute attachment. Only the adapter resolves native storage into a clean absolute path; Core never constructs one. A structurally valid directory is not itself ownership evidence.
+
+## Operations and outcomes
+
+Every control adapter implements `Declaration`, `Check`, `Create`, `Observe` and `Delete`. Every node attachment adapter implements `Resolve`. There is no optional side interface, implicit adapter substitution or nil implementation fallback.
+
+| Operation | Required meaning |
+| --- | --- |
+| `Declaration()` | Describe the selected configuration's verified attachment, user xattr and quota behavior. |
+| `Check(ctx)` | Validate configuration and availability without creating an object. |
+| `Create(ctx, reference)` | Create the owned object or converge on its existing attachment without overwriting data; retries and concurrent calls use the same immutable reference. |
+| `Observe(ctx, reference)` | Return an existing object's bound attachment without creating, repairing or preparing it. |
+| `Delete(ctx, reference)` | Converge on terminal deletion of the verified owned object after Core has authorized deletion and confirmed compute stop. |
+| `Resolve(ctx, binding)` | Validate native ownership and resolve the attachment for local compute. |
+
+Errors support `errors.Is`: `ErrInvalid` for invalid input, `ErrOwnership` for a reference or configuration mismatch, `ErrUnavailable` for unavailable storage, `ErrUnconfirmed` for an unknown mutation outcome, `ErrNotFound` for a missing object and `ErrUnsupported` for an unsupported combination. Adapters preserve these outcomes when wrapping errors. A missing observation does not prove an earlier mutation settled. A timeout or canceled context ends the caller's wait; it does not prove native stop or rollback. Core retains ownership on unknown outcomes. It may retry `Create` or `Delete` with the same persisted immutable reference and configuration, including after `ErrUnconfirmed`; it must never substitute a new object identity to retry an uncertain operation.
+
+Same-reference retry and concurrent convergence are mandatory adapter guarantees. `Create` preserves any existing object data and returns the attachment for that owned object; it never reinitializes a live object. Repeated and concurrent `Delete` calls converge on the same terminal deletion. Once terminal deletion is recorded, concurrent, delayed or retried `Create` calls must not resurrect the object, and `Resolve` must not expose it. Retained deletion metadata and further cleanup of settled in-flight operations are permitted. These guarantees apply to storage lifecycle operations; they do not establish mutation settlement at timeout or distributed compute fencing.
+
+## Capability validation
+
+`Requirements` declares the compute placement's attachment kind and need for `user_xattr`. `Declaration` reports the filesystem adapter's attachment kind, `UserXAttr` support and `CapacityQuota` enforcement. `ValidateCombination` is the shared pre-allocation admission check. The current attachment kind is `host_directory`; unknown kinds are rejected. A required user xattr capability means the mounted filesystem supports user extended attributes used by Environment preparation.
+
+A zero requested capacity means no quota was requested. A positive capacity in MiB is admitted only when the adapter actually enforces that limit; reporting available space or accepting an unchecked number is insufficient. The adapter's immutable configuration must enforce the admitted bound. Adapters cannot claim quota support based only on the Sandbox Provider's compute disk size.
+
+Workspace access is single-writer. Core must serialize compute ownership and confirm the previous writer stopped before attaching a replacement. There is no cross-VM lock capability in this protocol: a guest `flock` is not proof of a host lock or another guest's exclusion. A placement must not advertise concurrent-safe attachment based on guest-local locking.
+
+## Lifetime and filesystem scope
+
+The object contains the whole `/environment` tree, including the workspace, staging files, initialization state and package content. They remain on the same filesystem so filesystem operations within Environment preparation preserve their semantics. A Harness's private native history/configuration remains checkpoint state; it is not redirected into the workspace object.
+
+Workspace storage is retained with its Session until explicit Session deletion. Archival, expiration, reset and compute checkpoint deletion do not authorize workspace deletion. Core calls `Delete` only after explicit Session deletion and confirmed compute stop; unresolved compute or storage mutations retain ownership. Failed creation does not authorize deleting storage while its Session is retained. Snapshot-expiry recovery is not defined by this contract.
+
+## Kernel NFS adapter
+
+The `nfs` adapter uses an operator-premounted Linux kernel NFS filesystem. The supported setup is NFSv4.2 on trusted AUTH_SYS clients with `root_squash`, using the same export and absolute mount path on Core and nodes. The adapter neither mounts exports nor manages NFS credentials or service accounts. Other operating systems return `ErrUnsupported`. [Configuration](./configuration.md#independent-workspace-storage) owns installation steps and selection.
+
+Parameters contain exactly `root`, `namespace_id` and `uid`. `root` is a clean absolute mount path; `namespace_id` is a canonical nonzero UUID; `uid` is the nonzero effective host UID required on both Core and nodes. The initial deployment uses 65532. The operator prepares the mounted root with mode `0700`, owned by this UID, and a regular `.oac-storage-root` file with mode `0600`, owned by the same UID, containing exactly the namespace UUID followed by one newline. Do this on the export's server-side storage as its administrator; root-squashed clients cannot assume privileged ownership changes. The root marker is an assertion of the selected export's identity, not a credential or distributed lock.
+
+Construction validates and canonicalizes JSON without filesystem I/O. `Check` verifies the opened root is kernel NFS, the effective UID and private ownership/modes match, the namespace marker matches, and real file-descriptor `user.*` xattr set/get/remove operations succeed. Every filesystem operation, including opening the root and checking availability, runs within one process-wide budget of 32 in-flight operations. A timed-out caller receives `ErrUnconfirmed`; its slot remains occupied until the kernel call returns. An exhausted budget returns `ErrUnavailable`. Directory-descriptor-relative operations stay anchored to the opened root. An unavailable mount or a local directory at the configured path fails validation; no local fallback is created.
+
+The declaration is `host_directory`, `user_xattr: true`, `capacity_quota: false`. The native attachment contains only the namespace identity; resolution validates the complete binding against the immutable configuration and filesystem ownership before returning `objects/<ObjectID>/live/data` beneath the root. Only this data directory is exposed to the guest. Neither tenant nor application input supplies a host path.
+
+Each object owns `objects/<ObjectID>/identity`, `staging/`, `live/`, `trash/` and, after deletion begins, `deleted-marker`. The permanent identity binds the tenant, Environment and object UUIDs. Create prepares and syncs a private unique staging envelope before atomically publishing its nonempty directory as `live`; replay cannot overwrite existing live data. Delete first records a durable object-local terminal marker, retires live data to unique object-local trash and removes data before its ownership markers. Concurrent deleters converge. Minimal identity and deletion metadata remain intentionally; deletion does not mean every metadata file disappears. Create and Resolve refuse the retired identity. A late in-flight Create can leave empty controlled metadata requiring a repeated Delete after its syscall settles; it cannot authorize a new writer or reuse the object identity. Cleanup examines only that object's staging and trash, without a namespace-wide sweep or background service.
+
+NFS storage does not supply compute fencing or automatic distributed failover. Guest `flock` is not a cross-VM writer lock. The single-writer and explicit-deletion requirements above remain mandatory. The shared filesystem preserves `/environment`, while a Harness's private native history remains in its compute checkpoint; expiration of a native snapshot can therefore remove private history even while workspace files survive. Workspace retention alone is not a promise of resumable native execution after snapshot TTL expiry.

+### 独立工作区存储 {#independent-workspace-storage}
+
+首个支持的独立文件系统组合是 microsandbox 与[内核 NFS 适配器](./workspace-provider.md#kernel-nfs-adapter)。启动服务前，在 Linux Core 主机和所有参与节点上将同一个 NFSv4.2 导出挂载到相同的绝对路径，例如 `/srv/oac-workspaces`。运维人员负责导出、挂载可用性和服务启动顺序。使用带有 `root_squash` 的受信任客户端 AUTH_SYS 导出；不要启用 `no_root_squash` 或放宽权限来使检查通过。按照适配器的[所有权要求](./workspace-provider.md#kernel-nfs-adapter)准备命名空间和服务身份。
+
+Core 的 Compose 服务已使用 UID 65532 运行。添加节点前，创建同 UID 的 `oac-node`，主目录为 `/var/lib/oac-node`，使用 nologin shell 和非零主组。附加组只能包含其主组、`docker` 和 `kvm`；已有主目录必须属于该账户。安装器会接管此账户。如果没有预创建账户，安装器分配的系统 UID 不一定与 Core 一致。注册前应通过主机管理流程解决已有 UID 或账户冲突；修改运行中账户的 UID 不属于存储配置步骤。
+
+对于 Compose 部署，通过部署平台的 Compose 自定义能力，在现有 `core` 服务的 `volumes` 中添加可读写绑定挂载，保留现有服务卷和用户。主机源目录必须已经是 NFS 挂载；`create_host_path: false` 只防止创建不存在的源目录，并不能证明 NFS 已挂载。先挂载再创建容器；主机卸载或重新挂载后，应重新创建容器，使其挂载命名空间使用预期挂载。
+
+```yaml

+  core:
+    volumes:
+      - type: bind
+        source: /srv/oac-workspaces

+        read_only: false
+        bind:
+          create_host_path: false
+```
+
+按[管理 API](../../contracts/agents-api/zh/admin-api.md#workspace-storage)说明，使用 Core key 调用 `PUT /core/v1/workspace-storage` 选择存储。分别为不可变配置 `id` 和命名空间标记生成规范 UUID，然后使用实际值提交以下结构：
+
+```json
+{
+  "id": "11111111-1111-4111-8111-111111111111",

+  }
+}
+```
+
+随后通过[沙箱部署 API](../../contracts/agents-api/zh/sandbox-deployment.md#routes)创建或更新 microsandbox 部署，将 `resources.environment_disk_mib` 设为 `0`，并保留所需计算资源、Runtime 和 Provider 配置。正数表示请求配额，本适配器不实施此配额，因此会拒绝。部署的工作区要求和每个 Session 的挂载凭据均从已选数据库配置派生；不要向部署添加文件系统字段，也不要在节点文件中添加第二份存储配置。Web 没有工作区存储编辑器。

+上述路径位于 Docker 命名卷 `<project>_data` 中。所有宿主机平台都由 Docker 管理 Linux 文件权限；每个服务只挂载需要的子目录。数据卷必须和项目定义、公共 URL 一同保留。仅删除机密目录不会重置安装；数据库已存在时初始化会拒绝重建。Core 也会校验安装 ID 与数据库的绑定。运行时设置仍保存在 [Core 数据库](#runtime-settings-web)中。
 
 ## Docker 节点配置 {#docker-node-configuration}
 
-节点安装程序会将 Docker 的提供商配置写入节点的配置文件。部署资源、Runtime 镜像和容量仍存储在 [Core 的数据库](#runtime-settings-web)中。
+节点安装程序会将 Docker 的主机设置写入节点配置文件的 `native` 对象，只有 Docker 适配器读取它。部署资源、Runtime 发行版本和容量仍存储在 [Core 的数据库](#runtime-settings-web)中。
 
 | 字段 | 安装程序设置的值 | 含义 |
 | --- | --- | --- |
 | `host` | `unix:///var/run/docker.sock` | 显式 Docker Engine 套接字 |
+| `image` | 加载后 Runtime 镜像的本地 ID | 发行版本的 `image_id` 或 `image_manifest_digest`。主机的镜像存储决定由哪个 digest 指代已加载的镜像，因此该值属于节点本地；适配器只接受这两个值 |
 | `network` | `oac-node-<installation-id>` | Runtime 容器网络 |
 | `seccomp_file` | `<node-root>/runtime/seccomp.json` | 所匹配发行版的 seccomp 配置文件 |
 | `nested_sandbox` | `true` | 启用 Docker 适配器的 init 进程和 proc-mask 配置 |
-| `extra_hosts` | 可选 | 额外的容器主机映射 |
 
 [Docker 适配器](sandbox-provider.md#docker-adapter)负责容器隔离、卷布局和生命周期行为。
 
 ## 安装目录 {#installation-directory}
 
-安装程序会创建安装目录，默认路径为 `~/.oac/core`，权限模式为 `0700`。机密文件为 `0600`。
+安装目录默认为 `~/.oac/core`（Windows 为 `$HOME/.oac/core`）。其中保存进程设置和原生管理命令；服务持久数据位于 [Compose 数据卷](#compose-installations)。
 
 | 路径 | 内容 | 修改者 |
 | --- | --- | --- |
-| `.env` | [进程设置](#process-settings-configjson)。由你编辑的文件 | 你，然后运行 `oac apply`；托管域名设置写入 `OAC_PUBLIC_URL` |
-| `compose.yaml` | 发行版的服务定义。不要编辑 | 发行版 |
-| `oac` | [管理命令](getting-started/operations.md#the-oac-command)，从 Core 镜像复制 | 安装程序 |
-| `data/secrets/web/core.key` | [Core 密钥](getting-started/operations.md#core-key) | `oac rotate-core-key` |
-| `data/secrets/core/credential.key` | 加密 Core 在数据库中封存内容的密钥 | 无。必须与数据库一同保留 |
-| `data/secrets/core/core-key-digests.json` | Core 密钥的 SHA-256 | `oac rotate-core-key` |
-| `data/secrets/database/password` | PostgreSQL 密码 | 无。PostgreSQL 仅在创建数据库时读取 |
-| `data/database/` | PostgreSQL 数据 | PostgreSQL |
-| `data/node-payload/` | Web 在 `/node-install/` 提供的节点文件 | 初始化 |
-| `data/state/` | 私有 Provider 状态，包括 E2B 回执 | Core |
-| `.oac.lock` | 安装锁 | 会修改安装状态的 `oac` 命令 |
-
-Compose 项目名为 `oac-<10 hex digits>`。服务包括 `init`、`database`、`core` 和 `web`。Core 启动时执行数据库迁移。`web` 提供控制台并把 `/v1` 和 `/api/v1` 转发到 Core，是唯一发布端口（`OAC_WEB_PORT`）的服务。没有服务持有 Docker 套接字。除 Docker 存储外，不会向安装目录之外写入任何内容。
+| `.env` | 进程设置和固定的 Compose 项目名 | 用户修改后运行 `oac apply` |
+| `compose.yaml`、`compose-sha256sums.txt` | 已校验的发行版服务定义 | 发行流程 |
+| `oac`（Windows 为 `oac.exe`） | 原生管理命令 | 安装程序 |
+
+同级 `<install-dir>.lock` 目录用于同步操作并一直保留；`<install-dir>.staging` 保存尚未就位的安装文件。两者都不保存服务数据。Unix 上安装程序以 `0700` 创建私有目录，以 `0600` 创建配置文件。

 ## 附录：没有安装程序时的 Core 环境 {#appendix-core-environment-without-the-installer}
 
-Core 只读取其环境。Compose 把 `.env` 插值进服务环境。Compose 必须为 2.26.0 或更高版本。如果你自行运行 Core，请设置这些变量；见[服务指南](https://github.com/MiniMax-AI/OpenAgentCore/blob/main/services/core/README.md)。
+Core 读取进程环境。Compose 将 `.env` 插值到环境中，并把机密文件挂载到下表中的容器路径。直接运行 Core 时，将文件变量设为 Core 进程可读取的绝对路径；见[服务指南](https://github.com/MiniMax-AI/OpenAgentCore/blob/main/services/core/README.md)。
 
 | 变量 | 设置来源 |
 | --- | --- |
-| `OAC_PUBLIC_URL` | `public_url`，或 Core 的回环源地址。Core 从中派生守护进程 WebSocket URL、自托管 `remote_url`、托管沙箱地址和部署的只读 `core_url`，绝不从请求标头派生。未设置时，Core 不运行 Runtime 网关，也不执行任何 Session |
+| `OAC_PUBLIC_URL` | 必填。[公共 URL](#settings)。Core 只校验一次，并从中派生 Agents API 基地址、守护进程 WebSocket URL、自托管 `remote_url`、安装程序下载地址、托管沙箱地址和部署的只读 `core_url`，绝不从请求标头派生 |
 | `OAC_ADDR` | 安装程序在容器中设置为 `:8091`。独立启动的 Core 在未设置或为空时，默认使用 `127.0.0.1:8091` |

-| `OAC_DATABASE_PASSWORD_FILE` | `data/secrets/database/password`。此时 URL 不得包含密码 |
-| `OAC_CREDENTIAL_KEY_FILE` | `data/secrets/core/credential.key` |
-| `OAC_CORE_KEY_DIGESTS_FILE` | `data/secrets/core/core-key-digests.json`：一个包含 Core 密钥 SHA-256 的 JSON 数组 |
-| `OAC_INSTALLATION_ID_FILE` | `data/secrets/core/installation.id`：安装 ID，采用规范 UUID 格式。它会启用沙箱部署和节点路由，并要求设置 `OAC_PUBLIC_URL` 和 `OAC_CORE_KEY_DIGESTS_FILE`。如果 ID 与数据库记录的 ID 不一致，Core 会拒绝它，因此必须将两者一同保留 |
-| `OAC_EXECUTION_CONCURRENCY`、`OAC_DEFAULT_HARNESS`、`OAC_HARNESSES`、`OAC_WRITE_AUDIT_RETENTION`、`OAC_OAUTH_TRUSTED_ORIGINS` | 对应的[进程设置](#settings)。`oac-core check-config` 会在不启动 Core 的情况下校验它们 |
-| `OAC_HISTORY_SETTINGS_FILE` | 可选的 Runtime 历史文件。敏感；安装报告只说明它是否已设置 |
-| `OAC_LOG_LEVEL`、`OAC_LOG_FORMAT`、`OAC_LOG_ADD_SOURCE` | `log.*`；Web 也读取这三个设置 |
-| `OAC_PROVIDER_ROOT` | 适配器构件的绝对根目录。Core 镜像设置为 `/opt/oac`。每个适配器都拥有此根目录下的辅助路径 |
-| `OAC_PROVIDER_STATE_ROOT` | 绝对私有状态根目录：Core 镜像中为 `/state`。每个适配器都拥有自己的子目录；E2B 使用 `e2b/`，该目录归 Core 的用户所有，不允许组或其他用户访问。将其与数据库和 `credential.key` 一起备份；不要将其挂载到 Web 或 Runtime 中 |
-| `OAC_NATIVE_INSTALLER_DIR` | 自托管守护进程安装程序：Compose 文件中为 `/opt/oac/native-installers`。未设置时 Core 不提供安装程序。提供目录清单前，Core 会将其与自身发行版进行核对 |
-
-Core 会记录所加载文件的路径，但绝不记录环境变量的值或文件内容。
+| `OAC_DATABASE_URL` | 必填。不含密码的 PostgreSQL URL |
+| `OAC_DATABASE_PASSWORD_FILE` | `/run/database/password`。此时 URL 不得包含密码 |
+| `OAC_CREDENTIAL_KEY_FILE` | 必填。`/run/oac/credential.key`：Base64 编码的 32 字节随机密钥。Core 用它加密存储的凭据 |
+| `OAC_CORE_KEY_DIGESTS_FILE` | 必填。`/run/oac/core-key-digests.json`：一个包含 Core 密钥 SHA-256 的 JSON 数组 |
+| `OAC_INSTALLATION_ID_FILE` | 必填。`/run/oac/installation.id`：安装 ID，采用规范 UUID 格式。如果 ID 与数据库记录的 ID 不一致，Core 会拒绝它 |
+| `OAC_EXECUTION_CONCURRENCY`、`OAC_DEFAULT_HARNESS`、`OAC_HARNESSES`、`OAC_WRITE_AUDIT_RETENTION`、`OAC_OAUTH_TRUSTED_ORIGINS`、`OAC_HISTORY_SETTINGS_FILE`、`OAC_LOG_LEVEL`、`OAC_LOG_FORMAT`、`OAC_LOG_ADD_SOURCE` | 对应的[进程设置](#settings)。Web 也读取三个日志设置 |
+| `OAC_PROVIDER_ROOT` | 适配器构件的绝对根目录。Core 镜像设置为 `/opt/oac`。每个适配器都拥有此根目录下的辅助路径。当其中的 `native-installers/` 目录包含 `catalog.json` 时，Core 在核对该目录清单与自身发行版后提供自托管守护进程安装程序。适配器状态位于 `/state`，即数据卷的 [`state/`](#compose-installations) |
+
+Core 会记录所加载的历史文件路径，但绝不记录环境变量的值或文件内容。
 
 显式 OAuth 受信任源无效时，Core 会停止启动。条目必须是不含凭据、查询参数和非根路径的 HTTPS 源地址。[Vaults](../../contracts/agents-api/zh/vaults.md) 负责刷新和网络策略。私有颁发者还需要受信任的 CA：独立管理的 Unix Core 可以使用 Go 的 `SSL_CERT_FILE` PEM CA-bundle 覆盖机制，从而保留证书验证。托管安装没有自定义 CA 设置。
 
 ## 附录：没有安装程序时的 Web 环境 {#appendix-web-environment-without-the-installer}
 
-Compose 为 Web 设置这些变量。仅在不使用 Compose 运行控制台时才自行设置。该安装的机密信息中，Web 只收到 `data/secrets/web/core.key`。
+Compose 为 Web 设置这些变量。仅在不使用 Compose 运行控制台时才自行设置。Compose 把数据卷的 `secrets/web/` 挂载到 `/run/oac`，并设置 `OAC_WEB_CORE_KEY_FILE=/run/oac/core.key`。
 
 | 变量 | 默认值 | 含义 |
 | --- | --- | --- |

 本指南面向负责构建和发布 OpenAgentCore 的维护者。要安装 Core 和 Web，请使用 [安装指南](getting-started/install.md)。安装器代码遵循的规则见 [部署](https://github.com/MiniMax-AI/OpenAgentCore/blob/main/deploy/README.md) 和 [节点安装器](https://github.com/MiniMax-AI/OpenAgentCore/blob/main/deploy/node/README.md)；必需检查见 [CONTRIBUTING](https://github.com/MiniMax-AI/OpenAgentCore/blob/main/CONTRIBUTING.md#required-checks)。
 
 ## 构建分发包 {#build-a-distribution}

+
+Core、Web 和 ingress 镜像发布为经过校验的 Linux amd64/arm64 多架构索引。arm64 控制归档包含这三个镜像；Node、托管 Runtime 和离线包使用 Linux amd64。发行构建使用 QEMU 执行 ARM 镜像步骤，包括 E2B helper。宿主机 `oac` 从同一份实现构建为 Linux amd64/arm64、macOS amd64/arm64 和 Windows amd64 二进制；启动脚本只选择、校验并运行它们。所有版本索引校验通过后才更新浮动标签。

 合并的构建/发布作业使用具有 `packages: write` 权限的 `GITHUB_TOKEN`。首次发布时，GitHub 会将每个容器软件包创建为私有：软件包管理员必须先在各自的软件包设置中将全部四个软件包改为 **Public**，用户才能匿名拉取。请参阅 [GitHub container visibility](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry)。更改可见性后，请验证未认证拉取。仅更改仓库可见性并不会使新的容器软件包变为公开。
 
 GHCR 和 GitHub Releases 不共享事务。发布失败后，GHCR 中可能仍会保留一些匹配的版本标签；请保留这些镜像，并使用原始构件按照下文的草稿恢复流程操作。除清单缺失以外，注册表故障都会停止发布。作业摘要会记录按摘要固定的引用。这些镜像和渲染后的 Compose 文件仍需要[配置](configuration.md)中描述的配置、机密和路由。

 Go 检查和构建作业共享 `~/.oac/cache/` 下的 Go 模块和编译器缓存目录，缓存键由运行器 OS 和架构、全部 Go 模块文件、检查/构建分区以及提交确定。分区键可防止并发作业在同一个键下保存不同的编译器子集。发布构建既可以使用后端检查的缓存，也可以使用更早发布构建的缓存。较旧的缓存只会为下载和编译提供初始内容；每项检查仍会运行。发布作业还会缓存 npm 软件包下载内容和固定版本的 microsandbox 归档，并在每次构建时验证后者的校验和。Actions 缓存可见性遵循 GitHub ref 的作用域；特定标签的缓存不会与其他发布标签共享。只有作业成功后才会保存新键。

+单一 `SandboxProvider` 一并声明 `Initial`、`NewCompute`、`GetCompute`、`RenewCompute`、`Suspend`、`Resume`、`KillCompute`、`DeleteRetained`、`RunCommandCompute` 和 `ResumeCompute`：十项全部支持或全部不支持。生命周期不通过可选暂停接口或 Provider 名称分支选择。
+
+`RetainedState` 是 adapter 拥有的不透明信封，包含 `Reference`、`ID`、`Data`、`OperationID`、`SourceGeneration`、`SourceName` 和 `SourceID`。`Data` 必须非空且不超过 64 KiB。Core 原样保留信封并校验操作与源实例归属；不可变的 allocation Provider/代次绑定决定唯一有权解释它的 adapter。保留状态不必是独立快照：microsandbox 将完整原生快照身份放入 `Data`，E2B 保留带版本的原生暂停收据，不承诺独立磁盘镜像。adapter 在任何副作用前校验原生内容及归属。
+
+`Compute.RestoredFrom`、`ComputeState.Retained`、`ResourcesReleased`、`SuspendSettled` 和恢复的 `ReconcileOnly` 是结算证据。资源缺失不证明未知暂停已结束。`RenewCompute` 只续租精确实例；不确定结果不授权第二次创建、捕获或恢复。持久 `runtime_compute` 使用 `protocol_version: "1"`；启动拒绝缺失或未知版本。现有版本 1 信封可直接读取，无需改写。不会隐式转换只含 snapshot 的形状，也不会合成重放或丢弃保留状态。
+
+`ResumeRequest.Workspace` 携带 allocation 独立拥有的文件系统绑定；Core 在恢复前获取 ready 绑定。源实例必须已释放活跃执行能力，目标才可成为写者。adapter 在原生副作用前校验绑定；不支持独立文件系统的 adapter 拒绝非空绑定。`DeleteRetained` 仅删除 adapter 的计算保留状态，绝不删除 workspace。显式 Session 删除先完成 compute 清理，再删除独立存储，恢复期间保持单一活跃写者。
+
+Core 对所有声明暂停支持的 Provider 应用统一固定策略：工作空闲 5 分钟（300 秒）后暂停，保留状态期限为 24 小时（86400 秒）；部署的 [`suspension`](../../contracts/agents-api/zh/sandbox-deployment.md#safe-response) 返回这些值。Core 暂停已经初始化的 Environment，包括尚未执行 Turn 的 Environment，前提是没有 root 或 Subagent Turn 排队、执行或等待，没有输入、文件操作或初始化待处理，且真实活动已空闲达到该时长。Core 在同一事务中使用数据库时钟记录 allocation 的初始化完成和 root 或 child 终结转换。候选筛选和持有 Session 锁的复查比较数据库经过时间与空闲时长，初始保留状态期限也锚定同一数据库观测，因此 Core 与数据库主机的时钟无需一致。公开历史中的原生完成时间戳保持不变，但不驱动空闲准入，心跳也不重置活动时间。确认计划暂停前，daemon 关闭准入并排空原生清理、输出收据和文件工作。
 
-完整声明的 SuspensionProvider 操作组在直接和节点放置中使用同一生命周期。RetainedState 是绑定分配、源实例和操作的不透明 adapter 收据，其原生 Data 上限为 64 KiB；它不承诺快照语义。Core 从不解释原生 Data。Initial 和 NewCompute 规划精确逻辑实例而不分配资源；不同逻辑代次可保留相同原生 ID。GetCompute 仅观察。RenewCompute 为精确的运行实例续租而不唤醒它；公共运行路径在保持所有权或清除唤醒前先观察并续租。
+Worker 租约、Session 锁和每个 node 的 gate 负责所有 Provider 的暂停。新 Turn claim、文件写入意图和捕获准入在 Session 锁下串行化，共享计算阶段检查；新待处理工作取消捕获并唤醒同一源实例。正常准备在经过认证的恢复握手后等待计算阶段变为 running；待处理输入的提升与生命周期转换冲突时，输入保持 pending。计算阶段和经 revision 校验的收据存储在 allocation 中。Core 在副作用前持久化静止、捕获和恢复意图，仅新收据执行捕获或恢复；恢复流程观察精确尝试，不重试结果未知的创建、捕获或恢复。已消费的保留状态不会使运行中的代次回滚。删除、撤销和保留期到期始终优先于唤醒，直至最后的数据库 compare-and-swap；未知清理身份会一直保留，直到确认所属资源已不存在。已消费产物和旧计算实例会被删除，因此暂停循环不会累积可写磁盘链。
 
-Suspend 负责原生资源释放，返回绑定的保留句柄、suspended 状态、ResourcesReleased 和 SuspendSettled 后，Core 才释放活跃容量。ReconcileOnly 禁止重放原始捕获或暂停，但允许完成由持久保留产物证明安全的 adapter 清理。无保留状态的结果只有在带有 SuspendSettled 且源实例处于可恢复的运行或暂停状态时才允许回滚。其他所有不确定结果均保留所有权并关闭准入。Core 从不在 Suspend 后无条件销毁源实例。
+排队工作和实时 Environment 文件访问会唤醒暂停的 Environment；历史和已发布 Artifact 的读取不会唤醒。计划暂停在 daemon 连接上使用 Environment 与 suspension token。由 PID 和启动时间隔离的本地控制信号（`RunCommandCompute`）唤醒 parked daemon，daemon 在准入工作前重新认证。确认前的临时断连通过有界尝试和退避重试同一已准备好的暂停；永久认证或协议拒绝会将其关闭。Core 负责保留状态的到期期限，daemon 没有相应定时器。静止确认丢失时可以通过明确回滚解冻同一源实例，但不授权捕获。
 
-Resume 将保留状态恰好消费一次并恢复到预先提交的目标。恢复逻辑观察同一次尝试。Core 持久化 waking、认证并恢复 daemon、删除已消费的保留资源，然后提交 running 并准入工作。DeleteRetained 是幂等产物清理，会保留运行中的计算资源。清理失败会保持 waking 阶段，不能触发再次恢复。KillCompute 仍然是破坏性操作；清理旧代次时不得终止共享原生 ID 的较新活跃实例。
+`Suspend` 负责原生资源释放，返回绑定的保留句柄、suspended 状态、`ResourcesReleased` 和 `SuspendSettled` 后，Core 才释放活跃容量。`ReconcileOnly` 禁止重放原始捕获或暂停，但允许完成由持久保留产物证明安全的 adapter 清理。无保留状态的结果只有在带有 `SuspendSettled` 且源实例处于可恢复的运行或暂停状态时才允许回滚。其他所有不确定结果均保留所有权并关闭准入。Core 从不在 `Suspend` 后无条件销毁源实例。

+
+独立工作区文件系统边界由 [`workspacefs.go`](https://github.com/MiniMax-AI/OpenAgentCore/blob/main/services/core/internal/workspacefs/workspacefs.go) 定义。本文规定必需的集成契约，并不表示所有 Sandbox Provider 或执行位置均已实现。文件系统适配器拥有存储对象与原生挂载解析职责；[Sandbox Provider](sandbox-provider.md) 拥有计算资源职责。Core 在分配任一资源前选择并验证二者的组合。
+
+## 标识与配置 {#identity-and-configuration}
+
+`Reference` 包含 `TenantID`、`EnvironmentID` 和 `ObjectID`，均为不可变、规范小写且非零的 UUID。Core 在创建前持久化引用。对象标识永不复用，包括删除后或变更结果尚未确认时。适配器必须在暴露或删除对象前验证完整的归属元组。
+
+`Configuration` 是 Core 数据库中的不可变记录，具有规范 UUID `ID`、`Adapter` 标识和由适配器定义的 JSON 对象 `Parameters`。数据库是其唯一编写来源；更改配置须创建新的标识。Core 转发参数而不解释原生路径。现有对象始终绑定其原始配置。
+
+`Attachment` 将适配器签发的 JSON 对象 `Native` 绑定到完整引用、配置 ID 和挂载类型。它是内部归属凭证，不是应用提供的主机路径。共享验证检查信封结构以及预期引用和配置的匹配；所选适配器还必须验证参数、凭证及原生归属。结构有效本身绝不授权文件系统访问。公开 Session 载荷不得提供挂载凭证、配置参数或解析后的主机目录。
+
+`Binding` 临时携带配置和挂载凭证至节点解析器，不引入第二份持久化节点配置。`Resolver.Resolve` 验证绑定后返回用于本地计算挂载的 `Directory{Path}`。仅适配器负责将原生存储解析为规范绝对路径；Core 不构造路径。结构有效的目录本身不是归属凭证。
+
+## 操作与结果 {#operations-and-outcomes}
+
+每个控制适配器实现 `Declaration`、`Check`、`Create`、`Observe` 和 `Delete`；每个节点挂载适配器实现 `Resolve`。不得使用可选旁路接口、隐式替换适配器或 nil 实现回退。
+
+| 操作 | 必需语义 |
+| --- | --- |
+| `Declaration()` | 描述所选配置已经验证的挂载、用户扩展属性和配额行为。 |
+| `Check(ctx)` | 验证配置和可用性，不创建对象。 |
+| `Create(ctx, reference)` | 创建归属对象或收敛到其现有挂载凭证，不覆盖数据；重试与并发调用使用同一不可变引用。 |
+| `Observe(ctx, reference)` | 返回现有对象的绑定挂载凭证，不创建、修复或准备对象。 |
+| `Delete(ctx, reference)` | Core 授权删除且确认计算资源停止后，收敛到已验证归属对象的终态删除。 |
+| `Resolve(ctx, binding)` | 验证原生归属并为本地计算解析挂载。 |
+
+错误支持 `errors.Is`：`ErrInvalid` 表示无效输入，`ErrOwnership` 表示引用或配置不匹配，`ErrUnavailable` 表示存储不可用，`ErrUnconfirmed` 表示变更结果未知，`ErrNotFound` 表示对象不存在，`ErrUnsupported` 表示不支持的组合。适配器包装错误时保留这些结果。观察到不存在不证明先前变更已结束。超时或上下文取消只结束调用方的等待，不证明原生操作停止或回滚。结果未知时 Core 保留归属。Core 可以使用同一持久化不可变引用和配置重试 `Create` 或 `Delete`，包括收到 `ErrUnconfirmed` 后；绝不能通过替换新对象标识重试结果不确定的操作。
+
+同一引用的重试与并发收敛是适配器必须提供的保证。`Create` 保留现有对象数据并返回该归属对象的挂载凭证，绝不重新初始化存活对象。重复或并发的 `Delete` 调用收敛到同一终态删除。一旦记录终态删除，并发、延迟或重试的 `Create` 均不得使对象复活，`Resolve` 也不得暴露该对象。允许保留删除元数据，并在先前进行中的操作结束后继续清理。这些保证适用于存储生命周期操作，不表示超时时变更已结束，也不提供分布式计算隔离。
+
+## 能力验证 {#capability-validation}
+
+`Requirements` 声明计算位置的挂载类型及 `user_xattr` 需求。`Declaration` 报告文件系统适配器的挂载类型、`UserXAttr` 支持和 `CapacityQuota` 强制执行能力。`ValidateCombination` 是共享的分配前准入检查。当前挂载类型为 `host_directory`；未知类型会被拒绝。用户扩展属性能力表示挂载后的文件系统支持 Environment 准备流程使用的用户扩展属性。
+
+请求容量为零表示未请求配额。以 MiB 为单位的正容量仅在适配器实际强制执行该限制时获准；报告可用空间或接受未经检查的数字均不足够。适配器的不可变配置必须强制执行获准上限。适配器不能仅根据 Sandbox Provider 的计算磁盘大小声明配额支持。
+
+工作区仅允许单写入方访问。Core 必须串行管理计算资源归属，并在挂载替代计算资源前确认先前写入方已停止。本协议没有跨虚拟机锁能力：客户机内的 `flock` 不证明主机锁或对其他客户机的互斥。执行位置不得基于客户机本地锁宣称并发挂载安全。
+
+## 生命周期与文件系统范围 {#lifetime-and-filesystem-scope}
+
+对象包含整个 `/environment` 目录树，包括工作区、暂存文件、初始化状态和包内容。它们位于同一文件系统，以保留 Environment 准备期间文件系统操作的语义。Harness 的私有原生历史和配置仍属于检查点状态，不重定向到工作区对象。
+
+工作区存储随 Session 保留，直至显式删除 Session。归档、过期、重置和删除计算检查点均不授权删除工作区。Core 仅在显式删除 Session 且确认计算资源停止后调用 `Delete`；未解决的计算或存储变更须保留归属。Session 仍被保留时，创建失败不授权删除其存储。本契约不定义快照过期恢复。
+
+## 内核 NFS 适配器 {#kernel-nfs-adapter}
+
+`nfs` 适配器使用由运维人员预挂载的 Linux 内核 NFS 文件系统。支持的配置是受信任 AUTH_SYS 客户端上的 NFSv4.2，启用 `root_squash`，Core 和节点使用相同导出和绝对挂载路径。适配器不挂载导出，也不管理 NFS 凭据或服务账户。其他操作系统返回 `ErrUnsupported`。[配置文档](./configuration.md#independent-workspace-storage)负责安装步骤和选择方式。
+
+参数精确包含 `root`、`namespace_id` 和 `uid`。`root` 是规范的绝对挂载路径；`namespace_id` 是非零规范 UUID；`uid` 是 Core 和节点均须使用的非零有效主机 UID。初始部署使用 65532。运维人员将挂载根目录设置为该 UID 所有、权限 `0700`，并准备同 UID 所有、权限 `0600` 的常规文件 `.oac-storage-root`，内容精确为命名空间 UUID 加一个换行符。应由导出服务端管理员在服务端存储上完成此操作；启用 root squash 的客户端不能假定有权变更所有者。根标记声明所选导出的身份，并非凭据或分布式锁。
+
+构造函数只验证并规范化 JSON，不执行文件系统 I/O。`Check` 验证打开的根目录确实位于内核 NFS，有效 UID 与私有所有权和权限匹配，命名空间标记匹配，并且实际文件描述符上的 `user.*` xattr 设置、读取和删除成功。包括打开根目录和可用性检查在内的所有文件系统操作，共享每进程最多 32 个在途操作的预算。调用者超时后收到 `ErrUnconfirmed`；该操作仍占用名额，直到内核调用返回。预算耗尽返回 `ErrUnavailable`。相对于目录描述符的操作始终锚定已打开的根目录。挂载不可用或配置路径只是本地目录时，验证失败，不创建本地回退。
+
+能力声明为 `host_directory`、`user_xattr: true`、`capacity_quota: false`。原生挂载凭据仅包含命名空间标识；解析时根据不可变配置和文件系统所有权验证完整 binding，随后返回根目录下的 `objects/<ObjectID>/live/data`。仅此数据目录暴露给 guest。租户和应用输入都不提供主机路径。
+
+每个对象拥有 `objects/<ObjectID>/identity`、`staging/`、`live/`、`trash/`，以及删除开始后的 `deleted-marker`。永久标识绑定租户、Environment 和对象 UUID。Create 先准备并同步唯一的私有 staging 封装目录，再原子发布其非空目录为 `live`；重放不会覆盖现有 live 数据。Delete 先持久记录对象本地的终态标记，将 live 数据退役到唯一的对象本地 trash，再先删除数据、后删除其所有权标记。并发删除者收敛。最少量的标识和删除元数据会有意保留；删除不代表所有元数据文件均消失。Create 和 Resolve 拒绝已退役标识。迟到的在途 Create 可能留下空的受控元数据，需要在其系统调用完成后重复 Delete；它不能授权新写入者或复用对象标识。清理只查看该对象的 staging 和 trash，不全量扫描命名空间，也不使用后台服务。
+
+NFS 存储不提供计算 fencing 或自动分布式故障转移。Guest `flock` 不是跨 VM 写入者锁。上述单写入者和显式删除要求仍然必须遵守。共享文件系统保留 `/environment`，Harness 的私有原生历史仍在计算检查点内；因此，即使工作区文件仍然存在，原生快照过期仍可能导致私有历史丢失。保留工作区不代表原生快照 TTL 到期后仍可恢复原生执行。

 Each Turn ends with a result/error and `turn_settled`, independently of process exit.

 ### Registration and state
 
-For unmanaged bootstrap, daemon `connect` optionally registers this factory as `claude_sdk` when the operator sets `OAC_RUNTIME_CLAUDE_SDK_ENTRYPOINT` to the absolute packaged `dist/main.js`. `OAC_RUNTIME_CLAUDE_SDK_NODE` selects Node (default: `node` on PATH). Discovery resolves Node once and checks that exact configuration before pairing; the SDK's bounded runtime check is independent of CLI version probes. A ready SDK alone is sufficient to start the daemon. No configuration means no SDK probe or descriptor; failed readiness reports an unavailable descriptor with a rejecting factory. Runtime checks establish local readiness, not provider authentication. Installed daemons use `start` and their verified installation manifest for adapter selection and activation; ambient activation variables cannot extend that selection. See [the native installation contract](../../deploy/README.md#native-daemon-installer).

Background re-execution inherits operator configuration; it does not persist provider credentials in pairing profiles.

It accepts no caller-supplied environment variables or business write authority.

 Core owns public admission for Claude: [harness selection](../../contracts/agents-api/model-execution.md#harness-selection) chooses the engine for each Session; one [engine policy](../../contracts/agents-api/harness-onboarding.md#add-the-engine-to-core) serves API admission, device selection and the final claim; the [qualified operations](../../contracts/agents-api/harness-capabilities.md) table records Claude's medium-only verbosity and object-root function schemas; [function result images](../../contracts/agents-api/message-content.md#function-results) defines which placements accept image results; and [deployment defaults](../../contracts/agents-api/model-execution.md#deployment-defaults) define the model provider Core freezes for a Session. The adapter receives that provider as the adapter-owned `model_provider`, never in public Session configuration. Without one, a `none` host uses the daemon's own provider environment. The adapter alone selects the provider environment and removes credentials from native tool environments.

 ### Function server and results
 
-The internal SDK function-server helper uses the maintained MCP server's public request handlers and standard Tool/CallToolResult types. It snapshots definitions and forwards JSON Schema without a JSON Schema-to-Zod conversion; supplied tools are always loaded. Native call identity comes from the pinned harness's `claudecode/toolUseId` MCP metadata, independently of request IDs, names or arrival order. Missing identities and undeclared tools fail before invoking the host. Return content/error fields unchanged over MCP and forward its per-request abort signal. The private Go factory connects declared functions through this helper and reuses the daemon function-call/result interface and opt-in neutral observations. The native function-server registry must contain exactly those functions. SDK allowlisting admits only these host callbacks; the host still owns result decisions and any business permission checks. It grants no runtime-token business authority.

 Function results remain pending after stdin/MCP delivery. A matching live, root native user tool_result confirms application only when its Session/call identity, error flag and ordered content match the submission. Text matches exactly; each submitted image position must remain a valid native base64 image. Native resizing or re-encoding may change image bytes. This acknowledges incorporation into native history, not byte/pixel fidelity or completed provider consumption. Public Items retain the original caller content; real image-dependent model responses separately qualify usability. Ignore replayed, synthetic and subagent messages. Native error text joins the submitted text parts with newlines; neutral observations retain their original order and separate failure status. Missing/mismatched receipts fail the execution; do not replay unknown delivery. Result submission waits at most ten seconds for a receipt and cancels uncertain execution on timeout. Invalid or unsupported image results fail before consuming a pending call. Function state belongs to one live Run and ends with it; the router owns receipt retry/conflict handling. This does not establish crash recovery or exactly-once effects.

-"""Extract the pinned official Agents API route set and field names.
-
-Run this with a Python environment where the OpenAI Python SDK version pinned in
-contracts/agents-api/upstream.json is installed (``pip install openai==3.13.0``
-from that commit). It reads only the installed SDK source and types:
-
-    python3 scripts/extract-agents-api-upstream.py \
-        contracts/agents-api/upstream.json contracts/agents-api
-
-and writes ``upstream-routes.json`` and ``upstream-fields.json`` to the output
-directory. The public contract covers the Beta Agents resources
-(``openai.resources.beta.agents``), Files (``openai.resources.files``) and
-Skills (``openai.resources.skills``); see docs/api/public-agent-api.md.
-
-Routes come from each synchronous resource method's ``self._get``/``_post``/
-``_delete``/``_get_api_list`` call, with path parameters normalised to ``{}``.
-Field names come from the request params TypedDicts (``body=maybe_transform``),
-the query params TypedDicts (``make_request_options(query=maybe_transform(...))``)
-and the response models (``cast_to`` or ``page``) of the same calls, followed
-through nested models, TypedDicts, lists and unions. JSON names use the SDK's
-wire alias. Page wrappers are the SDK's hand-written classes, not generated
-wire types.

 ## Layering
 
-`api.NewHandler` takes one `api.Dependencies` value, built only in `cmd/server`. Each application area is one field typed as an interface declared in `api` beside its handlers, listing exactly the methods they call. Every field is required and `NewHandler` rejects a missing one, except the optional groups whose comments say what nil means: `Execution` is nil without an execution Worker, `Sandboxes` is nil without a managed sandbox installation and requires `Execution`, and `Execution.NativeInstaller` is nil for a build without a source revision. Handlers never discover a capability by type assertion or fall back to another implementation. API tests use one strict fake per area, `fake<Area>`, which fails the test on any call the test did not set.
+The domain packages own their vocabulary, pure rules and use cases: the domain owners listed below, `items`, `adminaudit`, `writeaudit`, and the shared vocabulary packages `environmentconfig`, `metadata` and `jsonobject`. No `internal` package except `persistence` and `db` imports an `internal/persistence`, `internal/db` or pgx package: they reach storage only through interfaces that the PostgreSQL adapters under `internal/persistence/postgres` implement and the commands under `cmd/` wire in. `TestLayering` in `cmd/server` checks these imports.
 
-`internal/persistence/postgres/pgunit` owns the PostgreSQL mechanics that adapters share: pooled read-write and snapshot transactions; pool-bound queries, used only for a single-statement read that needs no transaction, such as the per-request key lookup; the execution lease (its dedicated connection and gate, the ownership check, the cancellation fence, close, and the execution deadline); identifier parsing (`ParseID`, `PathID`, `LookupCursor`); and detection of text PostgreSQL cannot store (`IsUnstorableText`). Persistence code runs every transaction through it. Outside `persistence` and `store`, only `cmd/server`, which acquires the lease and builds the adapters' pool, and test fixtures import it. `internal/persistence/postgres/pgtest` is test support: it opens the dedicated test database under the `oac_*_tests` guard, applies the migrations, and creates isolated databases for database-wide state such as the execution lease. Only test files import it.

 `internal/persistence/postgres/auditpg` is the one adapter that other adapters call directly. Audit rows are written inside the business transaction, so each adapter calls `RecordWriteAudit`, `RecordAdminMutation` or `RecordDeploymentMutation` with its own transaction's queries; the audit provenance travels in the context. `writeaudit` and `adminaudit` own the sources, their validation, `ErrInvalidSource` and the read models, and `auditpg.Store` serves the audit reads.
 
-The adapter that stores a secret seals and opens it with the credential key `cmd/server` builds it with: domain storage interfaces carry plaintext, domain service constructors never take the key, a missing key is `credentialcrypto.ErrUnavailable`, and a ciphertext that fails to open or authenticate is an internal error, never a missing key, value or row.

-Two errors are shared across domains, each with one `api` helper: `textvalue.ErrUnstorable` (400, `writeTextValueError`) for text PostgreSQL cannot store, and `credentialcrypto.ErrUnavailable` (503, `writeCredentialUnavailableError`) for a missing credential key. The audit `ErrInvalidSource` errors pass through adapters unchanged, and `writeAuditSourceError` maps both to 400.
+One error is shared across domains, with one `api` helper: `textvalue.ErrUnstorable` (400, `writeTextValueError`) for text PostgreSQL cannot store. The audit `ErrInvalidSource` errors pass through adapters unchanged, and `writeAuditSourceError` maps both to 400. Each handler maps its operation's errors through that domain's mapper; Session operations that also meet the sandbox deployment, namely creation, input admission, archive and Runtime observation, map through `writeOperationError`, which tries `writeSandboxError` and then `writeSessionsError`.
 
-Shared vocabulary has one owner each, and domains use it rather than copy it. `internal/environmentconfig` owns Environment setup, Skills, Plugins and initial files with their validation and public metadata; `Setup.Validate` checks requested configuration, where a Skill may be an unresolved reference, and `Setup.ValidateInstalled` checks frozen, installable configuration. `internal/skills` owns `ParseVersion`, the canonical positive decimal Skill version. `internal/metadata` owns the metadata rules: `Validate` for the pair, key and value limits and U+0000, `ValidateStorable` for U+0000 alone, and `Encode` with its 64 KiB bound. `internal/jsonobject` owns `Normalize`, the stable encoding of stored JSON objects that snapshots and retry identities compare. These packages import no persistence.

-`internal/sessions` owns the Session vocabulary: Sessions, Turns, inputs, Environments and their provisioning failures, function calls, Item and Artifact reads, executor credentials, and the errors Session operations return, which `api` maps in `writeSessionsError`. It also owns the Session change vocabulary and its decisions: the public changes that report Turn and Session transitions, what a Turn that ends settles, measured Turn usage and the Session activity a change reports. Sequences that several Session operations share are `sessions` procedures, each over the transaction interface it declares: `CancelTurn` and `CancelWork` cancel work, `TrackInputActivity` reports the input activity a write changes, `FailEnvironment` and `TerminateEnvironment` settle an Environment that failed or whose managed compute ended, `CreateEnvironmentDevice` creates and binds a hosted Environment's dedicated Runtime device, `CheckComputeAdmission`, `CheckFileWriteGate` and `CheckInputStart` gate new work, `AdmitFunctionResult` saves a submitted function result for its Turn's call, and `LoadRequiredActions` lists the calls a Turn waits on. `AppendTurnEvents` records a batch of a Turn's execution observations, which `NewJournalBatch` validates, and `AppendTurnEvent` records its terminal outcome; both project the new entries. `ProjectSource` projects one journal entry or admitted input into Items, the root Turn's usage and Subagents, and `ProjectInput` projects an admitted input. `ValidTransition` decides the Turn status transitions, and the Subagent projection decides each Subagent's identity, lifecycle, child Turn and child Item changes. `sessions.ExecutionOperations` runs the Session writes only the execution owner makes; each function-call operation loads the Turn and its call in one leased Session transaction, decides in `sessions`, then applies in `sessionpg`, and `AppendTurnEvents` records and projects a Turn's journal batch in one leased Session transaction. `internal/items` owns public Items: it projects observations, merges them into stored Items and builds the ordered events that report each Item change. Neither imports persistence. `internal/persistence/postgres/sessionpg` loads the facts those decisions read and applies them inside the caller's Session transaction, under the Session lock: it allocates event sequence positions, event IDs, Item positions, output indexes and Subagent IDs, writes the change journal, each Turn's execution journal and its counters, Items, Turn usage, Subagent bindings, child Turns and child Items, and Artifact settlement, and prunes the change journal. It decides nothing. `WithSession` runs a Session operation's transaction on the pool or the lease: it locks the Session, applies the operation, then prunes the change journal. `BindSession` binds one Session to a transaction's queries as a `SessionTx`, which implements the procedures' interfaces.

-Other adapters call only these `sessionpg` participants, on their own transaction's queries: `LockSession`, which orders a write against the Session's Turns; `BindSession`, which runs a Session procedure, such as `CreateEnvironmentDevice`, in that transaction; `LoadEnvironment`, which reads the tenant's Environment of a live Session; and `CreateSessionEnvironment`, which stores the Environment of a Session being created. The other `sessionpg` exports serve `store` until the Session operations leave it. `tests/fixtures` is test tooling that composes procedures over a pooled `WithSession`, which is why `WithSession` and `BindSession` stay exported after store goes; no production code may do this. `deploymentpg` may import `sessionpg`, and `sessionpg` never imports `deploymentpg`; `placementpg`, which loads the placement facts and reserves placements, sits below both, so either may call it and it imports neither. Likewise `deployment` may compose the `sessions` procedures, and `sessions` never imports `deployment`.

-`store` is transitional. `store.New` builds a pooled Store, and `store.NewExecution(s, lease)` builds the execution writer on a lease it borrows. An execution-only operation on a pooled Store fails with `store.ErrExecutionAuthority`. New adapters do not copy that check: their execution repositories require a `*pgunit.Lease` at construction, their public repositories expose no execution operation, and the check goes away with `store`.
+Adapters' execution repositories require a `*pgunit.Lease` at construction, and their public repositories expose no execution operation.
 
-`cmd/server` owns the execution lease. It acquires one `pgunit.Lease`, builds every lease-bound adapter on it, and passes the lease and those adapters together as one `execution.Owner` to `execution.StartWorker`, which binds the Dispatcher to the Owner's execution operations through `Dispatcher.Bind`. If anything fails before that call, `cmd/server` closes the lease. From that call the Worker owns cleanup: a failed start closes the lease before it returns, and a started Worker closes it after `Run` has cancelled and drained its work. Each close runs under its own bounded deadline, independent of the cancelled request or run. Lease-bound adapters and the store writer borrow the lease and never close it, and the Worker uses the lease only through `Owner.Lease`, never through an adapter. Store integration tests start the Worker the same way through `startWorker`, and bind a Dispatcher that runs Turns without a Worker through `Dispatcher.Bind`.

-- `deployment` and its subpackage `deployment/placement` (`deploymentpg`, `placementpg`): the sandbox deployment and its nodes: provider configuration and the sealed credential, the specification and retained generations, setup, update and switch, node enrollment, identity and authentication, generation configuration, capacity, presence, status, host history, reset, and the counts of nodes and sandboxes bound to the public address; and hosted runtime allocations: reservation with the dedicated device, compute ownership and settlement, observation diagnostics, activity, compute phases, wake receipts and cleanup, with the reads that schedule, discover and authorize them. It interprets Sandbox Provider declarations through the `providers.Registry` it is given, whose lookups return typed errors. `cmd/server` builds that registry and calls it only to build a direct Provider and to discover a Provider's configuration; it takes each setup's mode and declared operations from the `Setup` that `deployment` returns. `deployment/placement` owns hosted admission and placement: `cmd/server` builds one `placement.Rules` from the registry and the public URL, both fixed while Core runs, and gives it to `deployment.Service` and to `store`; its pure decisions admit a hosted Session, choose its node, and admit an allocation's reserved node and a restore on it, and its errors keep one status, code and message through `writeStoreError` and `writeDeploymentError`. `placementpg` loads the facts those decisions read and applies them on the caller's transaction-bound queries; it has no Store or transaction runner. The only other reader is `store`: Session creation decides admission and placement with those rules and `placementpg` inside its own transaction. Deployment changes and allocation writes run through `deployment.ExecutionOperations` on `deploymentpg.NewExecution(lease, …)`, which the Worker receives as `execution.Owner.Deployment`. Each allocation write locks the owning Session, decides in `deployment`, applies in `deploymentpg` and prunes the Session's change journal in the same leased transaction; cleanup settles the Session through the `sessions` procedures on a `sessionpg.SessionTx` bound to that transaction. The Worker reads the deployment, prepares a selection's setup and records live-compute activity through the pooled `deployment.Service` in `execution.Dispatcher.Deployment`, and lists the Sessions a reset still has to archive, schedules node lifecycles and reads allocations through the pooled `deployment.Reader` in `execution.Dispatcher.DeploymentReader`; a pooled read carries no lease, and the leased write that follows it rechecks the allocation's owner. Node management and reads use the pooled `deploymentpg.Store`, which `cmd/server` also reads the owner epoch from and runs the host-history sampler on. Provider calls run outside transactions, and the final transaction rechecks the expected generation. The reset's Session archive stays in `store`.
-- `sessions` (`sessionpg`): Session use cases and reads as they leave `store`. The pooled `sessions.Service` runs the use cases on `sessionpg.Store`, which implements `sessions.Storage`, and plain reads use `sessions.Reader`, which `sessionpg.Store` also implements, directly. So far these cover root Items and Subagents (their reads), Session Artifacts (their reads, deletion and the staging of a Turn's export), Environments (their reads, the initialization list and the frozen setup and initial files, which `sessionpg.Store` opens with the credential key), devices (their reads, creation, revocation, heartbeats and Runtime enrollment), executor credentials (authentication and a Project's credential state through `sessions.ExecutorCredentialReader`, and issuance, rotation and revocation; the Core-key Project operations record their audit entry in the same transaction) and native installation authorization and claims, whose tokens `sessionpg.Store` signs with the credential key. `cmd/server` builds one `sessionpg.Store` with the credential key and wires the Service and the Store into `execution.Dispatcher.Sessions` and `SessionsReader`, into the api fields, into Runtime enrollment and into the daemon gateway; the Worker stages Artifacts through the Service; `cmd/environment-key` builds one without the key for its credential commands. Function calls and their application receipts, the Turn execution journal, Environment initialization, connection observations and their reconciliation, Session device binding, and file-write reservation and settlement run through `sessions.ExecutionOperations` on `sessionpg.NewExecution(lease)`, which the Worker receives as `execution.Owner.Sessions`.
+- `skills` (`skillpg`): Skills and their immutable versions: archive checks, the default and latest pointers, version selection and deletion, and each version's sealed archive. Session creation freezes selected versions inside its own transaction: `skillpg.LockSkills` locks the selected Skills in ID order, `skillpg.ReadVersionForFreeze` opens and verifies a version, and `sessions` selects each version with the `skills` rules.
+- `deployment` and its subpackage `deployment/placement` (`deploymentpg`, `placementpg`): the sandbox deployment and its nodes: provider configuration and the sealed credential, the specification and retained generations, setup, update and switch, node enrollment, identity and authentication, generation configuration, capacity, presence, status, host history, reset, and the counts of nodes and sandboxes bound to the public address; and hosted runtime allocations: reservation with the dedicated device, compute ownership and settlement, observation diagnostics, activity, compute phases, wake receipts and cleanup, with the reads that schedule, discover and authorize them. It interprets Sandbox Provider declarations through the `providers.Registry` it is given, whose lookups return typed errors. `cmd/server` builds that registry and calls it only to build a direct Provider and to discover a Provider's configuration; it takes each setup's mode and declared operations from the `Setup` that `deployment` returns. `deployment/placement` owns hosted admission and placement: `cmd/server` builds one `placement.Rules` from the registry and the public URL, both fixed while Core runs, and gives it to `deployment.Service` and `sessions.Service`; its pure decisions admit a hosted Session, choose its node, and admit an allocation's reserved node and a restore on it, and its errors keep one status, code and message through `writeSandboxError`. `placementpg` loads the facts those decisions read and applies them on the caller's transaction-bound queries; it has no Store or transaction runner. The only other caller is Session creation: `sessions` decides admission and placement with those rules over the `placementpg` participants inside the creation transaction. Deployment changes and allocation writes run through `deployment.ExecutionOperations` on `deploymentpg.NewExecution(lease, …)`, which the Worker receives as `execution.Owner.Deployment`. Each allocation write locks the owning Session, decides in `deployment`, applies in `deploymentpg` and prunes the Session's change journal in the same leased transaction; cleanup settles the Session through the `sessions` procedures on a `sessionpg.SessionTx` bound to that transaction. The Worker reads the deployment, prepares a selection's setup and records live-compute activity through the pooled `deployment.Service` in `execution.Dispatcher.Deployment`, and lists the Sessions a reset still has to archive, schedules node lifecycles and reads allocations through the pooled `deployment.Reader` in `execution.Dispatcher.DeploymentReader`; a pooled read carries no lease, and the leased write that follows it rechecks the allocation's owner. Node management and reads use the pooled `deploymentpg.Store`, which `cmd/server` also reads the owner epoch from and runs the host-history sampler on. Provider calls run outside transactions, and the final transaction rechecks the expected generation. Session archive crosses the Session and the deployment, so it is a `deployment.ExecutionOperations` operation: `ArchiveSession`, which the administrator's archive route calls through `api.Execution.SessionArchive`, and `ArchiveResetSession`, which a reset calls, lock the Session through `deploymentpg`'s `WithSessionArchive`, check the deployment's generation and the running reset in `deployment`, then expire the Environment and cancel its work through the `sessions` procedures, revoke the allocation's device and request its cleanup, and record the audit entry in one leased transaction. `deployment.ObservationResolver` resolves a Session's Runtime observation target for `runtimeobs` from `sessions.SessionReader` and `deployment.Reader`.
+- `coremetrics` (`coremetricspg`): the Core metrics PostgreSQL holds: the root Turn queue counts, the root Turn history, read from one read-only snapshot, and the database size. `cmd/server`'s Core metrics source adds them to the process, pool, Worker and daemon registry measurements.
+- `runtimehistory` (`runtimehistorypg`): Runtime history samples: the periodic export, scoped reads and retention, which also prunes node-host samples. `runtimehistory.Service` scopes a read to the Session's hosted Environment through `sessions.EnvironmentReader`.
+- `sessions` (`sessionpg`): Session use cases and reads. The pooled `sessions.Service` runs the use cases on `sessionpg.Store`, which implements `sessions.Storage`, and plain reads use `sessions.Reader`, which `sessionpg.Store` also implements, directly. These cover Sessions (their creation, reads, the change journal and stream snapshot, diagnostics, the frozen execution configuration, measured usage and archive state, metadata updates, deletion and the public write audit), Turns (their reads and the execution work scan), input admission (a public input batch, Environment input reservation and the expiry of one reservation, with the reads of a Turn's admitted inputs, a reservation and the Environment input work scan), the model provider a Session froze, which `sessionpg.Store` opens with the credential key, root Items and Subagents (their reads), Session Artifacts (their reads, deletion and the staging of a Turn's export), Environments (their reads, the initialization list and the frozen setup and initial files, which `sessionpg.Store` opens with the credential key), devices (their reads, which include a Session's execution binding and the execution device list, their creation, revocation, heartbeats and Runtime enrollment, and the archived cancellation receipt the daemon gateway reads), the administrator's views across Projects (a Project's asset counts and Sessions for the summary, and the Sessions whose Runtime the administrator observes), executor credentials (authentication and a Project's credential state through `sessions.ExecutorCredentialReader`, and issuance, rotation and revocation; the Core-key Project operations record their audit entry in the same transaction) and native installation authorization and claims, whose tokens `sessionpg.Store` signs with the credential key. Session creation runs in one pooled `sessions.CreationTx`: `sessions` validates the request, computes its retry identity, with the provider key fingerprinted by `sessionpg.Store` under the credential key, and orders the upsert, hosted admission, the Skill freeze, the sealed model provider, execution configuration, initial files and setup, the Environment, placement and the initial input; `FindSessionCreation` finds an earlier creation by its recorded intent. `cmd/server` builds one `sessionpg.Store` with the credential key and the Service with its `placement.Rules`, and wires the Service and the Store into `execution.Dispatcher.Sessions` and `SessionsReader`, into the api fields, into Runtime enrollment and into the daemon gateway; the Worker creates Sessions through the Service after its execution checks, waking the scheduler only after the commit, and stages Artifacts through it; `cmd/environment-key` builds one without the key, and the Service without placement rules, for its credential commands. Turn transitions, execution completion, which alone publishes or discards a Turn's staged Artifacts, the start of Artifact capture, function calls and their application receipts, the Turn execution journal, Environment initialization, connection observations and their reconciliation, Session device binding, file-write reservation and settlement, and the promotion, failure and bulk expiry of Environment input reservations run through `sessions.ExecutionOperations` on `sessionpg.NewExecution(lease)`, which the Worker receives as `execution.Owner.Sessions`.

-Source Files are Project resources with a lifecycle independent of copied workspace files. `files` owns their vocabulary, the upload envelope and 512 MiB content bound, the list rules and the create and delete use cases; `filepg` stores immutable source metadata and PostgreSQL large objects in Core's database with the pinned pgx driver. Upload validation, metadata insertion, the bytes and the write audit commit atomically; deletion removes the metadata, unlinks the object and records the audit in one transaction. Keep OIDs private and authorize every metadata, content and delete lookup by tenant before opening a body. Write content through `pgunit`'s large-object writer, which streams bounded chunks and reports the size and SHA-256 digest; never hold an entire upload in memory or use a filename as a filesystem path. A direct download of the `user_data` purpose is rejected after the tenant-scoped metadata lookup, while workspace copies keep their authorized `filepg` read and Session initialization copies read the object inside Session creation's store transaction. A read-only repeatable-read transaction preserves an admitted source across concurrent deletion; resolve that snapshot before entering the Environment write path, and a later deletion never undoes a completed workspace copy. Bound request and transaction lifetimes, roll back incomplete bodies and never retry an ambiguous commit automatically. Backups must include PostgreSQL large objects, and a schema rollback must not orphan them.

 Session Artifacts are immutable published copies, separate from live workspace files and source Files. The private output exporter reuses the authorized workspace path boundary and streams bounded bytes; publication requires complete capture and confirmed helper and transport success, not merely valid archive syntax. The daemon owns and drains the exporter's stdout pipe separately from child reaping, so pull-transport backpressure cannot consume the process-exit I/O deadline; after helper exit, each pipe read has one second, reset after consumer delays, which rejects inherited pipes that never close. Cancellation closes the owned reader and the dispatch consumer, then waits for the child. Never extract an output archive into Core's filesystem or hold the execution lease through a large transfer.

 Session deletion takes its decision and commits the `deleted_at` marker under the tenant Session lock that orders Turn and input admission, so either an admission commits first and deletion conflicts, or admission observes the deletion. Admission checks visibility under that lock before its retry lookup. Internal Turn, receipt, finalization and restart reconciliation keep access to deleted Sessions so that work settles under the execution lease; queued work of a deleted Session is never claimed, and Runtime cleanup still cancels pending work. Deletion never revokes a shared device or removes a saved Agent. Deleted Session records are retained, and a migration rollback refuses to drop the column while any exist.

 New saved-reference Sessions, and inline requests with Vault attachments or credential references, record a separate caller-intent hash: the source ID (empty for inline), supplied overrides with field presence, Environment and Vaults, original metadata and normalized initial input, excluding response streaming and resolved source values. Compare that same-tenant retry identity before looking up the source; a match returns the existing Session without input admission or source revalidation. Recheck after a source resolution failure for a concurrently committed creator, without holding a lock across resolution; the unique creation upsert stays authoritative. Credential-bound retries recover before reading mutable Vault contents. Every new hosted Session also records caller intent, before deployment defaults are resolved; the resolved-configuration hash of other inline Sessions leaves the deployment default out. Provider keys enter retry hashes only as keyed fingerprints.

 - Credentials are children of tenant-owned Vaults. Creation admits the owner in the same SQL statement as the insert; retrieval joins the owning Vault; listing enforces Project and Vault ownership on the parent, cursor and row query. Metadata queries never select ciphertext and need no encryption key.
-- `vaultpg` seals secret values before they reach SQL, with Core's separately configured random 32-byte key and the standard library's random-nonce AES-GCM. The versioned authenticated binding covers tenant, Vault, Credential, authentication purpose and exact destination. Never reuse daemon transport encryption for this storage. A missing key disables credential writes with `credentialcrypto.ErrUnavailable`; a malformed configured key fails startup.

The versioned authenticated binding covers tenant, Vault, Credential, authentication purpose and exact destination. Never reuse daemon transport encryption for this storage. A missing, unreadable or malformed key fails startup.
 - A static replacement is one SQL mutation scoped by tenant, Vault, Credential, auth type and destination, reusing the safe metadata for the immutable binding; it never decrypts the previous token, and a failed write keeps the old row.
 - OAuth refresh and replacement serialize on the Credential row lock, authenticate the stored grant metadata against its encrypted copy before using an endpoint, and persist the refreshed grant before returning an access token, so a stale refresh cannot undo a deletion or Vault cascade.
 - Credential deletion is one mutation checked by tenant, Vault and ID; Vault deletion removes the parent and its Credentials through the foreign-key cascade in one SQL statement, without decrypting, needing the key or calling providers.
 - At dispatch, Core rechecks the tenant, attached Vault, selected ID, frozen auth type and exact URL before scoped decryption, and the token enters only the transient daemon request. A missing key or binding failure never falls back to anonymous execution.
 
 - `credentialcrypto` ciphertext is a format version byte followed by the standard AEAD nonce, ciphertext and tag. The authenticated data holds a fixed domain and version plus the binding (tenant, Vault, Credential, auth type, exact destination). Keep the domain string unchanged: existing rows must still decrypt.
-- Random-nonce GCM allows at most 2^32 encryptions per key. `secrets/credential.key` also seals model providers, the E2B key, Skills, initial files and environment setup, so every sealed write counts toward that bound; there is no rotation or re-encryption path.

 - OAuth dispatch refresh holds the Credential row lock and the external exchange under one 20-second context (`vaults.oauthRefreshTimeout`). The refresh HTTP client has a 10-second overall timeout and 5-second TLS handshake and response-header timeouts, uses no proxy and treats any redirect as failure.

 Public Items read a projection updated in the same Session transaction as admitted messages and journal batches. Item IDs derive from the Turn and source identity, and the first-observation timestamp and tie breakers never change when content or status does. Each new Item's Session position is allocated under the Session lock, preserving observation order for equal timestamps, and each Turn allocates its own zero-based `output_index`, which inputs do not consume; updates and retries keep both.
 
-Item merging never mutates the incoming observation or the previous snapshot: public text delta events read the original fragment after merging, while the Item keeps the accumulated text, and the content slice is copied before its text pointer is replaced. A first observation without its own fragment carries its unchanged text in one delta. Wire-only explicit nulls come from response marshalling, while stored Item payloads keep their original encoding through `Item.MarshalStored`, so replayed child Items compare equal. Structured tool JSON is kept without float conversion, and an unfinished call never becomes a successful result.

 ## Worker ownership
 
-Enabling the daemon gateway with `OAC_PUBLIC_URL` also starts the execution Worker. One Worker owns an execution database through a `pgunit.Lease`: the PostgreSQL advisory lock held by one dedicated connection. A second Core on the same database cannot acquire the lease and starts no Worker. The Worker's execution writer runs every Session transaction on that connection: binding, claim and reconciliation, journal, Items and usage, function callbacks and receipts, and terminal state. The lease gate serializes these short transactions and the ownership pings, and `pgunit.ExecutionTimeout` (five seconds) bounds each one, including its gate and Session-lock waits. Cancelling an in-flight pgx operation can close the connection that owns the lock, so coordinator-owned work is cancelled only through the lease's cancellation fence, between leased operations. Never hold a transaction across daemon or model work, reconnect the writer or fall back to the pool after losing the lease. Public admission and device maintenance use pooled connections, and pooled reads grant no write authority. Transactions state their isolation: read committed for writes, read-only repeatable read for snapshots.

 - **Text verbosity.** The adapter reads the model catalog with `codex debug models`, checks the model's support and pins that catalog snapshot for the execution. The probe needs Unix process-group cancellation, so other hosts do not declare `text_verbosity`. For a model without declared verbosity support, including Codex's unknown-model fallback, `medium` omits the override and keeps native default text; a supported model receives an explicit `medium`. Unsupported `low` or `high` and an unreadable catalog fail before model execution.

 ## MCP servers
 
-A typed MCP declaration replaces operator MCP options. The adapter renders it with the native renderer and the original tool names for `enabled_tools`, including `[]`. Before creating or resuming a thread it reads native `config/read` with the exact cwd and rejects additional servers or any difference in the effective configuration. It disables native plugins and apps, selects file-only MCP credentials, and rejects existing credentials in the private native home without deleting them or native history. Reserved native labels are an adapter restriction, not a rule of the saved resource. The check is a snapshot, not a barrier against concurrent operator configuration changes, and discovery of a deny-all server can still contact it.

 With `required: true`, which needs `mcp_http_required`, root thread creation and cold resume wait for required servers to initialize and send no native Turn until they do; a failed strict resume is never replaced with a new thread. Public work may already be accepted while initialization waits.

 Workspace execution also requires the companion's readiness report: private protocol 2, the pinned native version and the pinned source revision ([`workspace_readiness.go`](../../../../apps/daemon/internal/agent/mcode/workspace_readiness.go)). An older companion is rejected even when the upstream version matches.

Names over 128 characters and metadata outside 16 string pairs with 64-character keys and 512-character values return invalid_request_error with the official param; U+0000 in stored strings is rejected as a local storage limit. As on every Agents API JSON route, a non-JSON Content-Type, invalid UTF-8, malformed JSON, a repeated key at any depth or a non-object root returns invalid_request_error with a null param and the official message before other checks; an empty or null body is {}. Missing, unknown, wrongly typed or unsupported enum members of the pinned configuration shapes (tools, text, reasoning, service_tier, multi_agent) return invalid_request_error with the JSON path as param; duplicate function names, repeated web_search or tool_search and non-object schema root types return it with a null param. Supports model/name/instructions/metadata, explicit reasoning and service tiers, multi_agent, text/json_schema, function/tool_search/programmatic_tool_calling/web_search and HTTP MCP with nullable credential_id, service origin (omitted or null on HTTP transport is saved as service) and boolean required defaulting to false. Saving credential_id grants no access: Session admission checks attached Vault ownership and destination. MCP allowed_tools preserves null versus empty; saved HTTP transport includes empty headers. Model-derived reasoning defaults, other MCP variants and public retry conformance remain incomplete. web_search saves every pinned mode: omitted or null mode is saved as live and omitted or null context_size as medium; allowed_domains preserves null versus empty and a present location, including {}, includes all four keys with null for omitted ones, as observed officially (req_db41d2f6261b4abfb69465eafe719ab5, req_165d53b88445490b9146d8272c54134d). Session execution accepts only explicit disabled web_search and disabled programmatic_tool_calling through qualified Runtime controls; saved enabled forms reject at Session admission. Session execution admits only its supported configuration subset.

Omitted OAuth access tokens preserve the existing grant when expiry or refresh fields change. Updates the existing static_bearer or mcp_oauth authentication method without network requests. OAuth access_token omission/null retains the token; a new token clears omitted expiry, explicit null clears expiry, and other omitted fields remain unchanged. OAuth refresh patches cannot add configuration or change client, endpoint, resource or authentication method; nullable token/client-secret values retain stored secrets while explicit null scope clears scope. Whole-null refresh and token_endpoint_auth retain existing configuration under local policy. Identity, destination, creation time and Session bindings remain unchanged. Responses expose safe metadata only. Already-dispatched work is not revoked; provider revocation, storage-key rotation and exact hosted concurrent-update/error semantics remain separate.

Well-formed unknown query keys are ignored; malformed query encoding and a repeated supported key are rejected. Sorts by case-sensitive path components, descending by default. Keep the same path, order and limit when using page. Each page rereads the complete bounded directory; changed file paths/sizes invalidate continuation locally with 400. There is no snapshot guarantee. An openai_hosted Environment that has not connected yet returns 400. Truncated or uncertain native results fail with 503 without returning a partial page. This read never starts a Turn or admits model input. Actual transport disconnect/reconnect events remain observable.

Initial files expose frozen safe metadata without content; Plugin/Skill entries expose only safe configured installation metadata. Capability-directory discoveries are not added to those arrays. Unsupported installation configurations remain implementation gaps. This read does not prepare execution, start compute or require an enabled execution worker. Session deletion removes the associated Environment from public reads; project-shared read authorization is unchanged. Connection status does not prove native readiness or process quiescence.

-// @Summary Create an execution Session
-// @Description The optional Core model_provider bundle resolves from the Session override, saved Agent defaults, then, for openai_hosted and none, the deployment default of the resolved harness; self_hosted never uses the deployment default and none accepts only it. openai_hosted and self_hosted Sessions that resolve no bundle return 400 model_provider_required with param x_agents_core.model_provider before any write. Core encrypts and freezes the resolved bundle; later Agent or deployment default edits and same-key retries cannot change it. Keys are never returned. Supports inline configuration or a tenant-owned saved agent_id with per-Session field replacements. Execution supports model/instructions, text verbosity, non-deferred function tools, adapter-qualified multi_agent with persisted Subagent reads, implicit reasoning, service tier auto and environment type none, subject to the configured engine. Codex additionally supports HTTP MCP with service origin (omitted or null on HTTP transport is saved as service), native allowed_tools and boolean required defaulting to false. Session vault_ids attach only project-owned Vaults; credential_id selects an attached static bearer or OAuth credential for the exact HTTPS URL, while null/omission selects a unique match or remains anonymous. Session reads, lists and event snapshots show that implicitly selected credential ID in a null or omitted credential_id, also after the credential is deleted; anonymous selections stay null and the stored caller intent is unchanged. After the input requirement and before any write, a credential_id without vault_ids, one outside the attached Vaults (one message for missing, foreign and unattached IDs) or one for another server_url returns 400 invalid_request_error, and several implicit matches return 409 conflict_error. Missing decryption configuration fails dispatch without anonymous fallback. Required initialization uses native startup before the first native Turn, including cold resume, and requires a separately advertised capability; exact hosted creation timing and error parity remain unverified. Explicit environment-origin HTTP MCP is supported on managed and self-hosted workspaces through the same Runtime bindings; native OAuth login remains unsupported. The self_hosted profile uses a qualified native harness, a clean absolute workspace_directory and optional absolute local capability_directories prepared by Runtime, with optional non-deferred function tools and HTTP MCP using explicit environment origin, optionally authenticated by the attached Vault rules. Service-origin HTTP remains restricted to service-side environment:none. Remote MCP and remote Bearer authentication each require separately advertised combination support; old peers cannot receive unsupported work. Omitted/null capability_directories use the empty-list default; self_hosted requires configured execution plus executor registry. Claude SDK currently requires medium verbosity and object-root function schemas. It supports anonymous or attached static-bearer service-origin HTTP MCP on none with boolean required and separately advertised MCP/bearer/required runtime support. Required servers must be connected before the first native input is released; pending or failed startup rejects execution. The shared Vault selection and immutable binding rules apply; unsupported native labels/tool names reject before persistence. An attached Vault with no matching credential may remain anonymous; missing keys or failed credential lookup/decryption never fall back to anonymous execution. Omitted stream defaults to false; stream and agent_id cannot be null. Metadata may be null; non-string values and limit violations return invalid_request_error with a metadata or metadata.<key> param. The inline agent uses the Agent create configuration validation with agent.-prefixed params, reported before the input requirement and saved-Agent lookup; saved configurations with conflicting tools or schema roots reject admission with the same errors, and execution limits keep unsupported_or_invalid_configuration. Hosted network policy rejections return invalid_request_error with a null param. Initial input accepts a string or ordered user-message array. Codex and Claude SDK on none and qualified managed or self_hosted workspace profiles also accept inline PNG/JPEG image content; other image combinations and remote URLs are unsupported. None initial input atomically starts a Turn; self_hosted initial input is reserved while returning its Environment connection target, with execution deferred to native readiness and Session failure on initial timeout. Initial input is required for none and for streamed creation outside self_hosted. Omitted/null input remains valid for non-streaming hosted and self_hosted creation. With stream=true, returns live Session events starting with the committed creation snapshot and closes right after the first agent.session.idle recorded when a Turn ends or an input reservation stops being pending, or any agent.session.failed, without sending later events. A creation that admitted nothing closes after the snapshot; a settlement that records no event closes after events up to the cursor read with a settled Session projection. Required actions keep it open; disconnect does not cancel execution. The GET events stream remains live-only. New Sessions retain their authenticated creator; all creation retries require the same typed subject, including across key rotation. Saved-Agent retries and inline requests using Vault attachments or credential references retain caller intent independently of later resource changes; new hosted inline requests also freeze caller intent before deployment defaults resolve; unrelated non-hosted inline retries preserve resolved/default equivalences, and their resolved hash leaves out any deployment default. Provider keys enter retry hashes only as fingerprints keyed by the credential key. Unknown historical creators reject retries; known creators without recorded intent retain resolved-snapshot retry rules. These conflict policies are local and not verified hosted parity. A same-key stream=true retry of an existing creation returns 201 with no events and closes at once; retry with stream=false or use the GET events stream to recover. Claude SDK on none, Core-managed Docker openai_hosted and self_hosted supports qualified object-root json_schema output with medium verbosity, single-Agent execution and ordinary functions. Hosted execution reuses native workspace tools and Files/Artifacts; Skills, Plugins, capability directories, HTTP MCP, Subagent and tool_search combinations remain unqualified, including inherited template contents. Other non-text initial input remains unsupported. Basic Codex and Claude SDK openai_hosted creation requires an explicitly configured managed provider. The Claude workspace profile supports non-deferred function tools with text or successful inline PNG/JPEG results alongside native workspace tools; explicit environment-origin HTTP MCP uses the common Runtime path. MiniMax accepts public environment-origin HTTP MCP only with null or omitted allowed_tools and required=false; even an empty non-null allowlist rejects. Idle Sessions provision automatically; initial provisioning has no caller connection action. Network defaults to enabled; disabled and restricted policies reject before compute allocation because the current Runtime cannot enforce them. The x_agents_core.environment extension accepts common preparation fields for either hosted or self-hosted placement: environment_template_id, files, env, packages, setup_commands, skills, plugins and capability_directories. Duplicate fields in environment and the extension reject. Confidential env, npm/Python packages and ordered setup commands use the same Environment-owned initialization lifecycle; compute allocation does not own preparation. Unknown side effects are not replayed after disconnect or restart. System dependencies must be preinstalled in the sandbox image or template, or on the host machine; packages.system is rejected. Initial inline and tenant-owned file_id files freeze encrypted bytes before provisioning, then install through the common Core lifecycle before native execution or live Files access. With a template reference, omitted/null files, env, packages and setup_commands inherit. Non-null files and command lists replace; env overlays by key; each package manager inherits on omission/null and otherwise replaces its list. Empty lists clear their selected field. Tenant-owned environment_template_id references inherit omitted/null network and allow only narrowing overrides. Inline hosted network:null retains the enabled default; updating a Template with network:null resets its saved policy to enabled. Core freezes effective configuration; template updates/deletion do not alter Session snapshots or same-intent creation retries. Inline or tenant-owned skill_reference Skills share initialization. Templates preserve default/latest/explicit selectors; Session creation freezes concrete metadata and encrypted content atomically. Skill, Plugin and capability-directory list omission/null inherit; a non-null list replaces, including empty-list clearing. Omitted/null Skill version selectors resolve the default version. Source deletion/default updates cannot change committed Session Skill contents. Deferred function discovery uses type-only tool_search and per-function defer_loading in the qualified single-agent Claude function profile on none or a managed/user-owned workspace, including qualified inline image messages and text results. Explicit web_search mode disabled and programmatic_tool_calling enabled false use frozen common Runtime controls. Enabled forms, including those saved on an Agent, remain unqualified and reject before any write unless the Session replaces tools. Omitted programmatic configuration preserves native behavior, a documented difference from the official default-on behavior. Other combinations remain unqualified; see the operation coverage.

-// @Summary Submit Session input events
-// @Description An empty events array is a resource-authorized no-op; it creates no execution retry identity, Turn, Item or input receipt. For environment none, atomically accepts text messages, cancellation and function results. Messages steer active work or start a queued Turn. Qualified Codex and Claude SDK workspace profiles accept text and inline PNG/JPEG messages, independently of managed or self_hosted ownership. Under the Session lock, matching retries retain their original target; new active messages append to the current Turn, while idle messages reserve work and wait up to the original five-minute connection/admission deadline. Return 202 only after durable admission, without claiming native application; active messages create no Turn or reservation. Cancellation-only prepared-environment batches use existing durable cancellation admission and return 202 without waiting for native exit; a new cancellation conflicts while a pre-Turn reservation is pending. Homogeneous tool_result-only prepared-environment batches reuse existing scoped result admission and application receipts without creating a Turn or bypassing a pending reservation. Mixed prepared-environment batches remain unsupported. HTTP expiry/cancellation use local 409 environment_input_expired/environment_input_cancelled errors. New input on a Session whose hosted Environment failed to provision returns the observed 409 conflict_error "the hosted environment failed to provision"; input already waiting when it fails and expired Environments keep the local 409 environment_unavailable. Input the Session cannot accept in its current state, such as a result after cancellation or a batch while earlier input is pending, and a result that differs from the call's saved result return 409 with type and code conflict_error; reusing an Idempotency-Key with a different batch returns the local 409 idempotency_conflict. Inside an owned Session, a result for an unknown call or for a call of another Turn returns 400 invalid_request_error and changes nothing; missing and foreign Sessions return 404. Losing execution ownership returns 503. The response write deadline accommodates the admission window for either prepared Environment, independently of new-hosted-admission and executor URL settings. Disconnecting the waiting HTTP request does not cancel retained work or restart its deadline. Retry keys identify the whole ordered batch. Function output accepts text or ordered text/image parts subject to engine support; Claude SDK accepts text results and, on none and qualified workspace profiles, successful inline PNG/JPEG results, preserving ordered content; error images and remote references reject before admission. Native image resizing may change bytes. Runtime image-result support is checked only for image-bearing delivery. Codex and Claude SDK on none and qualified managed or self_hosted workspace profiles accept ordered inline PNG/JPEG image messages. Other engines remain text-only; remote image URLs are unsupported. Image references are retained unchanged without service-side downloads.

-// @Summary List Vaults
-// @Description Lists project-owned Vaults independently of execution. An unknown, malformed or foreign after cursor returns not found. Includes active and archived records by default. Status accepts a scalar, the SDK's status[] array or both, filtering by their union; a repeated scalar is rejected. Limits default to 20 and clamp to 1–100. Equal creation times use ID ordering; exact hosted errors and concurrent-page behavior remain unverified. Archive/delete lifecycle is not implemented.

+// and ConfigurationAdapter the setup-time half. Every adapter implements every

+// through ProviderOperations, ConfigurationAdapter through Requirements. An
+// unsupported method returns a typed providercontract.UnsupportedError; method-set
+// presence never means support.

-[`helper_contract.go`](../../internal/sandbox/e2b/helper_contract.go) owns the adapter-private wire types, version, operation and error vocabulary, and bounds.

+[`helper_contract.go`](../../internal/sandbox/e2b/helper_contract.go) owns the adapter-private wire types, version, operation and error vocabulary, and bounds. Its generator projects Python declarations into the helper and template sources, deriving managed-bootstrap fields from the Sandbox Provider types, network access values from `agentnetwork.Policy.Validate`, and the SDK version from the hashed dependency lock. The command-input limit comes from its shared Go contract. The generated modules have no SDK or repository dependency and ship with the frozen helper and protected template startup scripts.
 
 Run `go generate ./services/core/internal/sandbox/e2b` from the repository root after changing these declarations. `make check-e2b-provider` and the Go adapter tests reject stale projections; both languages consume generated valid and invalid exchanges covering wire types, extra fields, operation/reference bounds and managed-bootstrap fields. The helper build copies those fixtures with its source before running the pinned-SDK suite.
 
-The boundary has version 3. The request and credentials arrive on standard input; standard output carries one bounded response with a sanitized error code. The helper removes ambient `E2B_*` and `PYTHON*` variables and calls the SDK only with the request's explicit API origin and sandbox domain. Each receipt is bound to those selectors, and a receipt without them belongs to the official endpoints (`https://api.e2b.app`, `e2b.app`). An endpoint change keeps earlier generations on their original API and sandbox domain; the candidate key must verify all retained ownership before an online switch.

 `bootstrap_run` also contains helper-side `bootstrap_stream_open` (the SDK background start call) and `bootstrap_stream_completion` (the existing handle wait, including command output draining). Guest timings on the same command stderr are filtered to `bootstrap_claim`, `bootstrap_protection`, `bootstrap_layout`, `bootstrap_credentials`, `bootstrap_spawn` and `bootstrap_receipt`, then exported through the same bounded Core log path. These cover the one-shot claim, image protection/account locking, workspace/environment layout, private credential persistence, daemon handoff and durable ready receipt. The helper accepts at most 8192 characters of guest diagnostics and one fixed four-field record per stage, at most 256 characters each; arbitrary stderr is discarded. Receipt JSON and command stdout are unchanged. Guest timings require a template containing the instrumented initializer; they remain unobserved on other templates. A stream failure can prevent guest timings from returning, even when initialization ran. Guest and SDK intervals overlap within `bootstrap_run`; do not sum them, or add daemon startup to provider completion. `bootstrap_spawn` confirms handoff only, and the daemon can start before the provider returns. All existing filesystem protection, fsync, no-replay and recovery behavior remains in force.
 
-`observe` reads each allocation's sandbox ID from its receipt without taking the allocation lock. It then runs one `GET /sandboxes/metrics` request and one labelled listing of the installation's running sandboxes concurrently, within the caller's deadline; the listing stops once every requested sandbox has appeared. Only a sandbox that the listing confirms for exactly that allocation is reported, with the listing's start time. A malformed metrics point makes only its row unavailable. Observation never connects to, renews or changes a sandbox and writes no receipt. [Runtime observability](../../../../contracts/agents-api/runtime-observability.md) owns the field mapping.

+The adapter implements the complete shared suspension group using opaque retained state. A native pause retains the same sandbox; it is not a portable filesystem snapshot. Core's common activity rule quiesces the Runtime, then the adapter calls the pinned SDK's memory-preserving `Sandbox.pause`. The private allocation receipt commits the operation before native I/O and reports resource release only after observing the exact sandbox paused.
 
 Resume calls `Sandbox.connect` once with `on_resume=restore` and the existing native timeout. It preserves the native sandbox ID while advancing the shared logical generation. Fresh connection material is persisted before returning running. Unknown pause and connect outcomes are observed without replay; a missing connect receipt keeps execution unavailable. The adapter fences stale generations before commands and deletion. Consumed pause receipt cleanup preserves running compute.

 ## Create and bootstrap

It creates the VM with the saved CPUs and memory as both initial and maximum, a managed root disk of `root_disk_mib`, an owned ext4 disk of `environment_disk_mib` mounted at `/environment`, user 1000:1000, working directory `/` and the node's network policy ([`bootstrap.go`](bootstrap.go)).

It creates the VM with the saved CPUs and memory as both initial and maximum, a managed root disk of `root_disk_mib`, an owned ext4 disk of `environment_disk_mib` or the explicitly resolved external directory mounted at `/environment`, user 1000:1000, working directory `/` and the node's network policy ([`bootstrap.go`](bootstrap.go)). The resource checks run before bootstrap.
 
-Workspace, staging and outputs share the `/environment` filesystem, which keeps the Runtime's cross-device and link checks intact; the layered root filesystem can report different device IDs for a directory and its upper-layer files, so it holds no workspace data. Full snapshots and sandbox removal capture, restore and reclaim this disk; there is no host path, external mount or separate storage lifecycle.
+Workspace, staging and outputs share the `/environment` filesystem, which keeps the Runtime's cross-device and link checks intact; the layered root filesystem can report different device IDs for a directory and its upper-layer files, so it holds no workspace data. In owned mode, full snapshots and sandbox removal capture, restore and reclaim this disk. In external mode, the filesystem provider owns the directory; sandbox removal never deletes it. The binding and resource rules belong to [Independent workspace attachment](../../../../docs/sandbox-provider.md#independent-workspace-attachment). Private HOME and history remain in the checkpointed root.
 
 VM creation does not run the image's entry point. The bootstrap runs as root through confidential standard input, with a two-minute limit. It creates the Runtime directories and the private control directory `/run/oac` (mode 0700, owned by UID 1000), writes the [Runtime bootstrap](../../../../docs/runtime-bootstrap.md) file to `/home/runtime/runtime-bootstrap.json`, bind-mounts `/environment/workspace` at `/workspace` and starts `oac-daemon connect --bootstrap-file` in the background as UID/GID 1000. `OAC_RUNTIME_DAEMON_SUSPEND_PID_FILE=/run/oac/daemon-suspend.json` enables the daemon's park and wake control. The `io.oac.bootstrap` label then changes from `pending` to `complete` through the SDK's next-start modification policy, because v0.7.2 cannot update the labels of a running VM. That label confirms only these writes and the launch, not authentication or native readiness.
 
-A helper response carries `CreateSettled` with a configuration rejection only after native Create has completed, the first inspection has verified the exact compute ID and ownership, and the resource check has rejected the VM before bootstrap started. The adapter keeps the original error and validates the compute identity before passing the proof to Core. Ordinary inspection, uncertain Create outcomes, timeouts and ownership failures never produce it, and missing compute alone never proves that Create settled.

The adapter keeps the original error and validates the compute identity before passing the proof to Core. The private `initial_info` operation used by `GetInfo` and `Renew` can also return an exact initial `State` with `Status="absent"`, no native ID and `CreateSettled=true`, after typed native absence and durable closure of initial Create admission under the allocation lock. It accepts only generation zero without restored ancestry or a native ID. The adapter validates the complete receipt and returns absence without an error. Ordinary `inspect` used by `GetCompute`, uncertain Create outcomes, timeouts and ownership failures never produce this receipt; missing compute alone is not settlement.

 A helper holds a per-allocation lock, under `oac-locks/` in the runtime home, until its SDK call actually settles. Core's response deadline neither kills the helper nor cancels its FFI wait, because cancelling the wait does not prove that the native mutation stopped. On a timeout Core keeps an unknown operation and observes it; a later helper cannot pass the surviving lock holder. A stuck owner needs operator investigation, not lock deletion or another Create.
 
+The same lock file fences a Create helper that has not yet acquired its lock, including across a node restart. An empty file permits initial Create admission; `closed\n` permanently forbids it, and any other nonempty content fails closed. Only `initial_info` observing typed native absence writes this marker while holding the lock, then synchronizes the file and its directories before returning the receipt. Every Create checks the marker under the same lock before invoking the SDK. Read, write or synchronization errors never establish settlement. The marker is never removed, and neither missing compute nor this receipt permits retrying Create.

 `RunCommand` and `RunCommandCompute` pass standard input on an anonymous pipe, run as UID 1000 with a deadline and a 1 MiB limit per output stream, and return a result only after the input is fully written and the guest reports its exit. Timeouts, output overflow and missing receipts return `ErrCommandUnconfirmed`; closing an SDK exec handle does not prove that the guest process exited ([`command.go`](command.go)). Core uses `RunCommandCompute` only to run the exact wake command it authorizes:

 The landing page has five numbered sections: the interactive combination example, an architecture image, execution lifecycle, console screenshots and installation. Four documentation shortcuts link to the detailed guides. `components/SessionFlow.vue` illustrates native execution, Core orchestration and multiple Session environments through a three-stage hand-drawn animation. It autoplays while visible and offers previous/next buttons, a stage slider and pause/play. Reduced-motion preferences disable autoplay. The diagram uses the locally bundled [Virgil font](https://github.com/excalidraw/virgil); its OFL license is stored beside the font in `.vitepress/theme/assets/fonts/`. Section headings share the hero’s display font with white text and green italic accents.
 
+### Launch video
+
+`components/LaunchVideo.vue` embeds the CDN-hosted launch film in the hero’s right column, below an interactive ASCII brand panel, in both languages. Green corner marks frame the preview. On narrow screens, the video fills the content width between the hero actions and installation command. The compact preview loops silently and has a pause control; reduced-motion preferences leave it paused. Opening the preview pauses it and continues from the same position in a modal player with native playback and audio controls. The close button, Escape and backdrop dismiss the player and return focus to the preview.

 ### Ecosystem logo wall
 
 `components/LogoWall.vue` places two full-width white logo rows between the documentation shortcuts and the closing installation section. The wall is transparent and borderless, allowing the landing page's background and grid to continue through it. Harness and model brands occupy the first row; cloud and compute brands occupy the second. They scroll in opposite directions, pause on hover or row keyboard focus, and have an explicit pause control. Reduced-motion preferences disable animation and leave both rows manually scrollable. Labels and controls use the landing page's English and Chinese copy.
