From e178ee78aa4df904cbba65427a019e26041efb8c Mon Sep 17 00:00:00 2001 From: Wave-is <120490463+Wave-is@users.noreply.github.com> Date: Mon, 14 Sep 2026 21:38:52 +0300 Subject: [PATCH 1/5] feat(coordination): persist evolving conversations and fence stale attempts Add opt-in SQLite journal with exact user messages/edits and attachments, replayable delivery receipts, project revisions, leased attempts and a single-writer/action-intent gate. Preserve late runtime evidence and fail closed on ambiguous tool effects. Summaries never replace original input. Add 53 offline tests and a synthetic failover smoke. Document the M2 live runtime ingress/tool integration boundary; no production or GUI changes. --- .gitignore | 8 +- docs/COORDINATION.md | 154 ++++++++ docs/HANDOFF.md | 30 ++ docs/VALIDATION.md | 21 ++ docs/WORKLOG.md | 20 +- src/coordination/__init__.py | 11 + src/coordination/store.py | 542 +++++++++++++++++++++++++++++ tests/test_coordination_journal.py | 478 +++++++++++++++++++++++++ tools/coordination_smoke.py | 57 +++ 9 files changed, 1319 insertions(+), 2 deletions(-) create mode 100644 docs/COORDINATION.md create mode 100644 src/coordination/__init__.py create mode 100644 src/coordination/store.py create mode 100644 tests/test_coordination_journal.py create mode 100644 tools/coordination_smoke.py diff --git a/.gitignore b/.gitignore index e0cab70..12a4d8d 100644 --- a/.gitignore +++ b/.gitignore @@ -1,4 +1,4 @@ -__pycache__/ +__pycache__/ *.py[cod] *$py.class *.log @@ -24,3 +24,9 @@ secrets.*.yaml *.pfx /Мои хотелки к первой версии.txt /Предложения для второй версии от чатгпт.txt + +# Private managed-conversation journals (including SQLite sidecars). +*.sqlite3 +*.sqlite3-wal +*.sqlite3-shm +*.sqlite3-journal diff --git a/docs/COORDINATION.md b/docs/COORDINATION.md new file mode 100644 index 0000000..5dbcec3 --- /dev/null +++ b/docs/COORDINATION.md @@ -0,0 +1,154 @@ +# Managed coordination: durable conversation first + +Status: **M1 implemented, opt-in library + offline smoke; not connected to live +Qwen/Hermes input or tools yet.** This does not change the installed alpha.1 EXE. + +## Why a summary is not the source of truth + +The user's task evolves during a conversation. A model may omit a new restriction +from `PROJECT_STATE.md`, misunderstand it, or disappear before writing any handoff. +Therefore an LLM is never responsible for persisting user input. The input boundary +must write each original message/edit and its attachments before returning a +successful receipt to the frontend, queue or agent. Failure to commit is a failed +send, not permission to continue without a journal. + +`src/coordination/JournalStore` provides this boundary. SQLite is local to the +coordinator PC, with WAL, FULL synchronous writes, transactions and foreign keys. +This protects acknowledged data against process failure within SQLite/filesystem +semantics, not against storage hardware failure, malicious local access or loss of +the entire machine. Backups remain necessary. Do not place a live database on SMB. + +A future integration opens `data_dir()/coordination/journal.sqlite3` explicitly. +Importing the package creates nothing. The library uses only Python's standard +library, starts no processes and contacts no model servers. Runtime databases, +attachments, conversations and local raw logs must never be committed to Git. + +## Implemented contract + +1. `open_project`: register an explicit workspace. A second project ID cannot bind + the same normalized workspace and bypass the project-level single-writer check. +2. `append_user`: exact UTF-8 text, stable source/message ID and optional stored + attachment digests. Return is a durable receipt, including event ID and revision. + Repeated delivery of the same source ID/content returns the same event. Reusing + an ID with different content is an error. Retries must keep the original ID. +3. Edits append a new `user.edit` pointing to the old event ID; no overwrite. Every + human message conservatively advances the project revision, even a clarification + or acknowledgement. No model classifies a message as 'unimportant' for storage. +4. `put_attachment`: content-addressed immutable bytes + media type, stored in the + same database; a screenshot is not merely a path to a disappearing temporary file. + Limits: 20 MiB per attachment, 16 digests per user event, 1 MiB per event payload. + Unsupported size is an explicit error; never silently truncate an input. +5. `record_runtime_event`: exact assistant chunks/messages, tool output and notices + from trusted adapters. These remain evidence, not user commands. Late output from + revoked attempts can be retained without restoring the old attempt's authority. +6. `create_task` and `start_attempt`: each task has a monotonic attempt epoch and + expiring lease. Explicit replacement or expiry revokes the old attempt. Writers + are exclusive within a project; multiple read-only attempts are permitted. +7. `prepare_delivery`: a persisted/replayable packet contains **all original user + events**, including edits, plus the current task's history. A model-authored + summary cannot replace them. The adapter supplies a local tokenizer/budget + counter which must account for the actual chat template, tools and images. + Overflow raises `ContextOverflow` instead of truncating or silently compressing. +8. `acknowledge_delivery`: the trusted transport acknowledges a particular packet + ID/digest/revision. An input arriving in transit invalidates the old receipt. + This is evidence of delivery, **not proof of semantic comprehension**. It is not + a tool which the LLM can call to claim it has read its own instructions. +9. `begin_action`: before a tool is launched, require the current attempt, unexpired + lease, delivered current revision, appropriate write permission and no unresolved + previous action. Persist the intent first. Duplicate tool IDs raise an explicit + conflict rather than running again. The adapter, not the model, classifies tools. +10. `finish_action`: preserve output even if the model/lease/revision became stale. + Such output is `needs_review`, never automatic success for the new attempt. +11. `cancel_attempt`: revoke future admissions. This does NOT terminate an OS process + and does NOT remove uncertain running actions. Reassignment waits for an operator + to verify process/files and call `reconcile_action` with a note/current revision. +12. `finish_attempt`: require the current revision and resolved tools, then propose + `awaiting_review`. A model's 'done' is not a claim that tests or requirements pass. +13. `record_summary`: optional derived text with an explicit source high-water mark. + It never advances a user's revision or an attempt's delivery acknowledgement. +14. `events` / `task_status`: ordered audit stream and task state for future UI. + +Example: user says 'use SQLite', later 'keep the existing schema'. The second message +is committed as revision 2 even if the model writes a summary mentioning only SQLite. +An attempt which saw revision 1 cannot start another tool. After failover, the new +attempt's delivery packet still contains both exact messages. A delayed tool request +from the old attempt is refused. If an old tool was already running, automatic +replay stops for reconciliation rather than executing its side effect twice. + +## Integration boundaries: do not overclaim + +- This is not a new coding harness or a chat UI. External agents still perform + reasoning and tools. Existing Station model/GPU/frontend profiles stay independent. +- The current `QwenCodeAdapter` reports `task_control=False`. No live ingress hook, + steering hook, GUI edit hook, stream subscription or tool gate is wired in this PR. + Opening the existing Qwen Desktop therefore does NOT enable these guarantees. +- A model-API proxy alone is insufficient: it sees model requests, not necessarily a + user edit/queued message immediately when entered in the agent UI. The input adapter + must observe the authenticated human-message boundary *before* dispatch/acknowledge. +- If that hook is unavailable in an installed runtime, mark capture as observational + or unsupported and disable automatic authority transfer; do not invent an endpoint, + edit its private session database or ask the model to remember to save messages. +- The library refuses stale **admission**. It does not sandbox arbitrary file access, + prevent an external agent bypassing it, or undo a command already executing when + a correction arrives. A future local tool executor must check current admission, + enforce workspace/approval rules, track owned processes and stop/drain safely. +- Read-only attempts must not receive an unrestricted shell labelled 'read-only'. + A source role ('human' vs assistant) comes from a trusted adapter, never from text. +- SQLite and the API are not an authorization boundary against malicious code running + as the same user. Keep DB/private files in the user's data directory with suitable + permissions; no network control port, secrets headers or tokens in audit metadata. +- End-to-end exactly-once model/tool execution is not claimed. Packets are replayable, + duplicate ingress is idempotent; ambiguous external actions block automatic retry. +- SQLite leases use an injected UTC clock for persistence. Significant clock rollback + needs explicit reconciliation; a process-restart scheduler must not trust old OS + process ownership based only on a PID or assume a lease means a process was killed. +- Project-level revision invalidation is deliberately conservative. Later task-scoped + routing must not silently omit project-wide changes. A new smaller-context leader + currently receives all raw inputs or fails on overflow; selective source-linked + handoff and user-approved scope reduction are later work, not a hidden lossy fallback. +- Backup via SQLite's backup API or a closed database; copying only a live .sqlite3 + without its WAL can omit committed records. Retention, encryption at rest and + explicit user deletion/export UX are follow-up work. + +## Verification + +Run from source: + +```text +python -m pytest -q tests/test_coordination_journal.py +python tools/coordination_smoke.py +``` + +The smoke creates only temporary synthetic data. It demonstrates an omitted +constraint in a model summary, a newer human message, failover and stale-attempt +rejection. It does not start a model or modify the installed Station. + +Tests cover retries/conflicts, exact Unicode and edits, attachments, transaction +rollback, concurrent ingress, one writer, lease expiry, immutable-record triggers, +replay after restart, context overflow, new input during delivery and during a tool, +late results, cancellation, operator reconciliation and untrusted runtime evidence. + +## Next milestones (not implemented by M1) + +**M2: one real Qwen runtime adapter, fail-closed.** Pin/probe installed protocol; +intercept every new/edited/queued human input, store it before acknowledgement, +subscribe to output with persistent source IDs/cursors, and gate every tool through +managed admission. Preserve raw input independently of model summaries. Expose +capture coverage and delivered revision in Station. Unsupported channels stay +explicitly unprotected; no automatic failover there. + +**M3: deterministic node/task dispatcher.** Reuse Station model/service registries; +resource-pool slots (not one worker per alias), enabled/paused/ready/loading/busy/offline, +allowed trust boundary per project, one leader, priority and backoff, task-scoped +handoff with provenance, no silent cloud fallback or context shrink, process-aware +cancellation and reconciliation. Do not modify GPU modes or remote services merely +because a model becomes unavailable. + +**M4: optional Station controls.** One project/task view with raw conversation, +revisions, leader and worker sessions, queued user corrections, source links, +conflicts and explicit approvals. Use official agent sessions, not a second coding +agent. Requirements edits remain raw events regardless of UI or selected model. + +First production acceptance: safe fault injection in a disposable repository, +user edits during generation/tool execution, delayed output after failover and +application restart.

Preserve edits and attachments before dispatch; block ambiguous replay and keep HTTP 202 separate from model delivery. Implement authenticated External Tool Guard v1 with persistent request fencing and current revision/attempt admission. Add 78 synthetic SQLite/HTTP tests and smoke.

The Guard and daemon use +separate tokens. Local guard HTTP rejects browser Origins, unexpected Hosts, +missing/wrong authentication, duplicate JSON keys and oversized requests. It has +no public network listener and does not log payloads.

Native Desktop, direct daemon/ACP, Telegram and extension ingress can bypass + this facade.

Original M1 tests are unchanged. + +Broader local run: **279 passed, 1 skipped, 1 deselected**, excluding +`test_gpu_confirmation.py`, `test_startup.py` and one UI callback test because +customtkinter is unavailable. A full run initially failed on that missing dependency; +pip installation was blocked by container networking. No dependency was stubbed. +Full Windows/Linux matrix and installer verification are delegated to the existing +PR CI; report its actual outcome separately.

Exact human messages/edits and queue rows +commit atomically; dispatch records intent before one HTTP POST. Ambiguous results +block replay. HTTP 202 is kept separate from model delivery and tool completion. + +Reviewed the upstream external Tool Guard v1 at f024b37689f3abab4bbfb249f44af55d34effc77. +Implemented its two authenticated loopback routes, strict contract parsing, explicit +tool allowlist, current delivery/revision/attempt fencing and persistent request/tuple +replay refusal. Unknown/nested/background tools deny. No OS tool is launched by this +module; actual results require a trusted observer. Fixed the capabilities fixture +against upstream: features is an array, not an invented boolean map. + +New tests: 78 passed. M1+M2a together: 131 passed. Both synthetic smokes PASS. +Broader local regression: 279 passed, 1 skipped, 1 deselected, with two GUI-dependent +modules excluded because customtkinter is missing; attempting dependency installation +failed on unavailable network. No UI stubs or fake full-suite claim. CI runs the full +unchanged matrix and Windows packaging separately. No new dependencies. + +Next M2b: native input/steering and live SSE cursor/epoch + result/delivery evidence, +then actual owned-process draining. Existing Desktop/Telegram conversations remain +unprotected and automatic failover disabled until those integration tests pass. diff --git a/src/agents/qwen_code/adapter.py b/src/agents/qwen_code/adapter.py index 7aa46fc..306261d 100644 --- a/src/agents/qwen_code/adapter.py +++ b/src/agents/qwen_code/adapter.py @@ -58,6 +58,18 @@ def get_capabilities(self): 'daemon': bool(re.search(r'^\s*qwen serve\s', self.help_text, re.M)), 'provider_sync': self.schema_confirmed, 'task_control': False}) + def get_coordination_capabilities(self): + # This must NOT turn task_control on for existing Desktop/CLI sessions. + from .managed import coordination_coverage + return Result(Support.DEGRADED, + 'Managed outbox/Guard primitives only; native ingress and runtime observation are not wired', + data=coordination_coverage()) + + def open_managed_input(self, **configuration): + """Explicit developer entrypoint; no startup, provider edits or network on open.""" + from .managed import ManagedQwenInput + return ManagedQwenInput(**configuration) + def get_config_locations(self, workspace=None): home = Path(self.settings.get('home') or os.environ.get('QWEN_HOME', Path.home() / '.qwen')).expanduser() paths = {'user': str(home / 'settings.json')} diff --git a/src/agents/qwen_code/managed.py b/src/agents/qwen_code/managed.py new file mode 100644 index 0000000..a3ae5d2 --- /dev/null +++ b/src/agents/qwen_code/managed.py @@ -0,0 +1,76 @@ +"""Opt-in durable ingress for callers that control the Qwen input boundary. + +This facade is not installed into Qwen Desktop/Telegram automatically.

Resume only read-only event GETs; gaps, changed epochs, stale observers and missing tool outcomes block new permits. Join terminal-before-202 races without replaying uncertain prompt mutations. Add 89 synthetic SQLite/HTTP tests and an explicit event smoke. Keep native UI capture, full-packet delivery, owned-process drain and automatic failover gated.
