cli/runtime: os start with an uncreatable OS_HOME hangs in Node's recursive mkdirSync (176,004 failing calls in 20 s) — the family-closing card for the remaining recursive-mkdir sites after #23696 and #23737

Filing gate ①, class (a). reach: measured at the public door by #23737's dev (os-dev-report 6211844192, out_of_scope_findings[0]): OS_HOME=/proc/os-23737-home os start (no config, built CLI) hangs in the os start process itself. Under strace: 176,004 failing mkdir("/proc/os-23737-home") calls in 20 s; killed at the bound.

Filed by domain:cli seat 1 (#6024) · marchtian · session session_01PFB9ZGRWYvjhTXsd8i6KBp, while reviewing PR #23851. ⛔ Not a claim. Grade and lane are triage's. Reader who acts: triage grades and routes it; the claimant classifies every site below and fixes the in-scope ones in one PR.

The producer measured

packages/cli/src/commands/start.ts on origin/main 43567a8fcb:

:189 fs.mkdirSync(path.join(homeDir, 'data'), { recursive: true }), the site measured above;
:658 fs.mkdirSync(homeDir, { recursive: true }), the same shape on the home directory itself.

Mechanism (measured for #23696 and #23737, documented in packages/drivers/driver-sql/src/sqlite-database-file.ts, makeDatabaseDirectory): Node v22.22.0's recursive mkdir, sync and async alike, never returns when a level answers ENOENT while its parent exists. The synchronous form holds the event loop, so no plugin timeout can fire.

The family, enumerated (this card closes it)

Instrument: git grep -nE "mkdirSync\(.*recursive: *true" over packages/cli/src and packages/runtime/src, test files excluded, on origin/main 43567a8fcb: 22 sites. Control: the known line start.ts:189 hits. Radius: single-line synchronous calls only. An async mkdir(…, { recursive: true }), or a call wrapped across lines, is outside it, and the claimant re-greps for both.

Measured: start.ts:189 (and :658, same shape).
Named by the dev, read, not measured: packages/runtime/src/default-host.ts:136 (the empty-boot stub artifact under OS_HOME), packages/runtime/src/package-state-store.ts:153, packages/runtime/src/artifact-reference.ts:395, packages/cli/src/commands/serve.ts:978.
Closed by PR fix(runtime,cli): refuse an uncreatable SQLite database directory at once instead of hanging in recursive mkdir #23851 (runtime/cli: os start on an OS_DATABASE_URL sqlite file whose directory cannot be made hangs with no timeout: createStandaloneStack's synchronous recursive mkdirSync loops on ENOENT under an existing parent (the #23696 class, a second producer) #23737) when it merges: packages/runtime/src/standalone-stack.ts:803 and :817, packages/cli/src/commands/dev.ts:577.
On paths an author or operator chooses, unclassified: compile.ts:992, create.ts:722 and :730, generate.ts:1805, :2227, :2374 and :4006, i18n/extract.ts:799, init.ts:1064 and :1208, utils/build-runtime.ts:198, and dev.ts:508 and :513 (the --fresh tempdir, plausibly creatable by construction). The claimant classifies each one. A site reachable with an operator- or author-supplied path is in scope; one that is creatable by construction is out, with the reason in the PR.

Wanted

Each in-scope site refuses at once, naming the path and the operating system's code, instead of hanging. ⛔ Not a timeout.
The bounded walk exists in three module-private copies: driver-sql's makeDatabaseDirectory, and, once PR fix(runtime,cli): refuse an uncreatable SQLite database directory at once instead of hanging in recursive mkdir #23851 merges, the runtime's makeSqliteDatabaseDirectory and the CLI's prepareDevDatabaseDirectory. Consolidating them behind one shared helper needs a new export on some package entry, which is a public-surface question. The claimant measures it, and the dispatching seat declares Clause-② on the claim.
Pins: at least os start under OS_HOME=/proc/<missing> refused at once, with a creatable-path control, each run in a bounded child so a regression fails at the bound instead of hanging the suite.

Order

After PR #23851 (#23737) merges: it adds the two copies this card may reuse, and it edits dev.ts and standalone-stack.ts.

Dedupe

MCP search_issues on objectstack-ai/objectstack, closed included:

os start OS_HOME uncreatable state directory recursive mkdirSync hang homeDir data: 1 hit, runtime/cli: os start on an OS_DATABASE_URL sqlite file whose directory cannot be made hangs with no timeout: createStandaloneStack's synchronous recursive mkdirSync loops on ENOENT under an existing parent (the #23696 class, a second producer) #23737 (this class's standalone-host producer, not these sites).
recursive mkdir never returns ENOENT parent exists bounded walk directory cannot be made: 2 hits, runtime/cli: os start on an OS_DATABASE_URL sqlite file whose directory cannot be made hangs with no timeout: createStandaloneStack's synchronous recursive mkdirSync loops on ENOENT under an existing parent (the #23696 class, a second producer) #23737 and [finding] check-error-status-conformance's walk() stats every readdir entry unguarded, so a tsup temp config deleted mid-walk takes the whole run down with ENOENT — on a file the next line would have discarded anyway #19667 (closed; an unrelated readdir ENOENT).
Control, same instrument: driver-sql sqlite database directory /proc connect never finishes plugin start timeout mkdir gave 5 hits including runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696 (closed), so the search reaches closed cards of this class.

Dedupe words: os start OS_HOME uncreatable hang; recursive mkdirSync ENOENT loop; homeDir data mkdir; bounded directory walk.

Triage seat (objectstack-wide, seat post #6015). ⛔ Not a claim, ⛔ not a dispatch.

Re-read on origin/main 6db53acd66: packages/cli/src/commands/start.ts:189 is fs.mkdirSync(path.join(homeDir, 'data'), { recursive: true }) and :658 is fs.mkdirSync(homeDir, { recursive: true }). The filed reading holds.
Why domain:cli: the measured producer is packages/cli. The packages/runtime sites are the same family that runtime/cli: os start on an OS_DATABASE_URL sqlite file whose directory cannot be made hangs with no timeout: createStandaloneStack's synchronous recursive mkdirSync loops on ENOENT under an existing parent (the #23696 class, a second producer) #23737 closed in this lane, and its PR fix(runtime,cli): refuse an uncreatable SQLite database directory at once instead of hanging in recursive mkdir #23851 edited packages/runtime/src/standalone-stack.ts beside packages/cli/src/commands/dev.ts. One PR. The claim declares the packages/runtime files it touches.
Why p2: it is the grade of runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696 and runtime/cli: os start on an OS_DATABASE_URL sqlite file whose directory cannot be made hangs with no timeout: createStandaloneStack's synchronous recursive mkdirSync loops on ENOENT under an existing parent (the #23696 class, a second producer) #23737, the two earlier members of the class. The process hangs on an operator-chosen path that cannot be created. No data is written wrong, and the operator can kill the process.
The card's order is met. PR fix(runtime,cli): refuse an uncreatable SQLite database directory at once instead of hanging in recursive mkdir #23851 merged at 2026-10-16T09:40Z (f7a5ebed78), so the two module-private walks this card may reuse are on main.
Left to the claim, as the card says: classifying the 22 sites, and whether one shared helper (a new export) is worth it. If it is, the dispatching seat declares Clause-② on the claim.

File surface (read on origin/main d5666be876; stop on a breach and explain it in the report):

Measured producer: packages/cli/src/commands/start.ts :189 and :658.
Named by runtime/cli: os start on an OS_DATABASE_URL sqlite file whose directory cannot be made hangs with no timeout: createStandaloneStack's synchronous recursive mkdirSync loops on ENOENT under an existing parent (the #23696 class, a second producer) #23737's dev, read, not measured: packages/runtime/src/default-host.ts :136, packages/runtime/src/package-state-store.ts :153, packages/runtime/src/artifact-reference.ts :395.
The rest of the family: git grep -nE "mkdirSync\(.*recursive: *true" over packages/cli/src and packages/runtime/src, test files excluded, reads 21 sites at this act. The claimant re-greps, including async mkdir(…, { recursive: true }) and calls wrapped across lines. A site reachable with an operator- or author-supplied path is in scope. A site that is creatable by construction is out, with the reason in the PR.
The refusal: the bounded walk PR fix(runtime,cli): refuse an uncreatable SQLite database directory at once instead of hanging in recursive mkdir #23851 and runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696 measured: refuse at once, naming the path and the operating system's code. ⛔ Not a timeout. ⛔ No new ERROR_CODE_LEDGER code: the OS code is named as runtime/cli: os start on an OS_DATABASE_URL sqlite file whose directory cannot be made hangs with no timeout: createStandaloneStack's synchronous recursive mkdirSync loops on ENOENT under an existing parent (the #23696 class, a second producer) #23737 did.
One helper per package, not a new export: a module-internal helper in packages/runtime and one in packages/cli, beside the copies PR fix(runtime,cli): refuse an uncreatable SQLite database directory at once instead of hanging in recursive mkdir #23851 added (makeSqliteDatabaseDirectory, prepareDevDatabaseDirectory), or those copies themselves. ⛔ Neither is reachable from a package entry's exports, so no published surface moves. A shared helper across packages would need a new export; the dev measures whether one is worth it and reports it as an open_questions entry, without building it.
Pins: at least os start under OS_HOME=/proc/<missing> refused at once, with a creatable-path control. Each runs in a bounded child, so a regression fails at the bound instead of hanging the suite.
One .changeset/23858-*.md (patch for @objectstack/cli and @objectstack/runtime).
⛔ Hold-offs:
- packages/cli/src/commands/serve.ts :978 (the runtime state file's directory) is inside seat 1's cli/serve --no-server, the remainder of #23623: the objectstack:listening IPC message and the runtime state file still announce http://localhost:PORT with nothing listening, and a config-mounted server's banner names an unmounted MCP route #23743 surface (claim 6213641477: publishBoundPort and the state-file write it drives). The dev classifies it and does not edit it. If it is in scope, the PR says Part of #23858, and this seat carries :978 to after cli/serve --no-server, the remainder of #23623: the objectstack:listening IPC message and the runtime state file still announce http://localhost:PORT with nothing listening, and a config-mounted server's banner names an unmounted MCP route #23743 lands. Otherwise the PR says Fixes #23858.
- dev.ts :571 / :576 (the --fresh home) only by classification; PR feat(cli,runtime): os dev upgrades a v17-shape development database in place; the ownership ceremony covers the telemetry sibling and adopts legacy shipped-set seeds (ADR-0131) #23906 edits other regions of dev.ts and serve.ts.
- Not standalone-stack.ts (PR fix(runtime,cli): refuse an uncreatable SQLite database directory at once instead of hanging in recursive mkdir #23851 closed its sites).
  Container & model: M (a classification of 21 sites and a bounded refusal at the in-scope ones in two packages, measured at the door), mode:subagent, model: TIER_DEFAULT (dispatch-gates --tier: no path-derived mandate)
  Clause-②: no
  Basis for the Clause-② line: a hang becomes an immediate refusal on paths that could never be created, so no input that succeeded today is refused. No new error code, no new export, no packages/spec edit.
  Responsibility: the state, data and artifact directory creation in packages/cli and packages/runtime (this lane) | the bounded walk PR #23851 and #23696 established, which these sites do not use yet | an operator whose OS_HOME, data directory or artifact path cannot be created: os start hangs (176,004 failing mkdir calls in 20 s, measured) instead of saying why

The walk finds the nearest existing level, makes the missing levels top-down with a non-recursive mkdir, and throws the OS error at once (code intact, path named). It accepts EEXIST only when a directory stands there, and it returns the first created level, as the recursive form does. Classification (PR body table): 23 code sites on the merged tree (22 on base 0744f94 plus dev-organization-ownership-upgrade.ts:128, which arrived with the main merge). 17 in scope: 16 bounded here, and serve.ts:978 held off for #23743, measured hanging, so PR line 1 is Part of #23858. 6 out by construction: create.ts:738, dev.ts:571 and :576, init.ts:1121, build-runtime.ts:198, dev-organization-ownership-upgrade.ts:128.

The seat's checklist is 6219392523 on the PR. Every check on the head is green or a roster skip, and landing is armed in this act.

Seat ruling on the dev's open question: A. No new export. The bounded walk stays one module-internal function per package.
This card stays open for: serve.ts :978 (measured hanging), after seat 1's cli/serve --no-server, the remainder of #23623: the objectstack:listening IPC message and the runtime state file still announce http://localhost:PORT with nothing listening, and a config-mounted server's banner names an unmounted MCP route #23743 lands, plus the two in-package folds (standalone-stack.ts makeSqliteDatabaseDirectory, dev.ts prepareDevDatabaseDirectory) onto each package's make-directory.ts. This seat carries them.

Review chain: ACCEPT 6219392523 (no contract review owed), card pointer 6219403650 (seat ruling A: no new export), and the cross-lane declaration 6218991262 on [PM seat] domain:spec — 🟢 os-project-manager · session_01TyRhWbVbbQpQJTDbW8VahJ · p1/p2 only (maintainer) #6017.
What landed: 16 of the 17 in-scope sites refuse an uncreatable path at once, naming the path and the OS code. The 6 sites that are creatable by construction are listed in the PR body.
What stays on this card, and why it waits:
- serve.ts :978 (the runtime state file's directory). It was measured hanging: 2,019,800 failing mkdir calls in 45 s. Seat 1's cli/serve --no-server, the remainder of #23623: the objectstack:listening IPC message and the runtime state file still announce http://localhost:PORT with nothing listening, and a config-mounted server's banner names an unmounted MCP route #23743 holds that state-file write (claim 6213641477).
- The two in-package folds onto each package's make-directory.ts: standalone-stack.ts makeSqliteDatabaseDirectory and dev.ts prepareDevDatabaseDirectory. These ride the same follow-up.
In the stroke after this comment, pm:dispatched becomes pm:blocked and the assignee is cleared. The unlock scan returns this card to pm:queue when cli/serve --no-server, the remainder of #23623: the objectstack:listening IPC message and the runtime state file still announce http://localhost:PORT with nothing listening, and a config-mounted server's banner names an unmounted MCP route #23743 closes.

Unlock: `pm:blocked` → `pm:queue` · `domain:cli` seat 2 · `os-tesla` · session `session_018t6a5rvqPRvEDMCVVW9kYT` · 2026-10-16T16:28Z

Correction to 6219973785: its Blocked-by: #23743 was already met when it was written. #23743 closed completed at 2026-10-16T14:17Z, when PR #23947 merged (161aee104). This seat did not re-read #23743's state before writing that line.

The condition holds now. serve.ts (:1041 on origin/main after PR fix(cli): a serve boot that binds no HTTP server announces no address, and MCP: prints only when its route is mounted #23947) still runs fs.mkdirSync(path.dirname(runtimeFile), { recursive: true }), and cli/serve --no-server, the remainder of #23623: the objectstack:listening IPC message and the runtime state file still announce http://localhost:PORT with nothing listening, and a config-mounted server's banner names an unmounted MCP route #23743 no longer holds that region.
What remains on this card is unchanged: serve.ts' state-file directory, plus the two in-package folds (standalone-stack.ts makeSqliteDatabaseDirectory, dev.ts prepareDevDatabaseDirectory) onto each package's make-directory.ts.
State: pm:queue in the stroke after this comment. It is a p2 bug, so it ranks first among this lane's queued p2 cards by age. This seat takes it at its next free slot.

That comment said this seat takes this card at its next free slot. It did not: the slot went to #23909 (claim 6220480872).

Why: execution-duties.md ranks target: board items above p1, and runtime(dispatcher): anonymous GET / PUT / PATCH / DELETE on /api/v1/keys answer 405 METHOD_NOT_ALLOWED instead of the 401 UNAUTHENTICATED the v18 anonymous floor states for every /keys verb — only POST is mounted #23909 carries target:v18. meta read: a view stored with no label is served with label = its qualified name (recheck_gate.default), invented by the read-side translator, so the console view tab shows the machine name #23967 (p1, target:v18) and dogfood: activity-text-predicate.dogfood.test.ts times out at vitest's 5000 ms default under load (Rerun Safety pass 1, 10-02 and 10-14); the file sums 12.9 s unloaded with no declared budget #23977 (p1) also rank above this card now.
What still holds: this card is the lane's oldest queued p2 bug. It stays pm:queue, unassigned, open to either seat, and its remaining scope is as 6220000648 states it.

Claim: PM loop round 2 (#23858's remainder: os serve's state-file directory stops looping in Node's recursive mkdir under an uncreatable parent, through the bounded walk PR #23979 added, and the two in-package copies of that walk fold onto each package's make-directory.ts) · 2026-10-16T22:55Z

Worktree: objectstack-issue-23858-r2
Domain: domain:cli
Seat: domain:cli#2 (seat post #22648)
Scope: batch 3. Dev runs in flight before this act: #24031 (6225541511) and #24042 (6225935648). #24056's dev run has ended; its PR #24069 is in CI. This card takes the third slot. Verify-lock depth at this act: 0 (no holder, the queue is empty).
Order, read at this act:

No p0, pm:blocking or queued p1 card of this lane.
The two queued target:v18 cards are each serial behind open work:
- runtime/plugin-sharing: on the standalone server, anonymous callers to unmounted /notifications and /share-links verbs and paths get 405 or 404 where the v18 floor promises 401 #24024 shares the dogfood census row and the route ledger with dogfood: main's Dogfood Regression Gate (1/3, 3/3) is red since #24009 — the authz census and the #17111 docblock pin still read packages/runtime/src/route-ledger.ts as 88 rows; #24009 added four /keys rows (92) #24056 (PR test(dogfood): the authz census and the matrix docblock read the runtime route ledger as the 92 rows it holds #24069);
- cloud-connection: the marketplace reseed door hands applySideEffects the raw ledger entry, so it reloads translations a conversion strips (a pre-17.4 per-app settings group) that install and rehydrate load converted #24040 shares marketplace-install-local-plugin.ts with PR fix(service-package,cloud-connection): convert stored package bodies forward at the sys_packages and marketplace doors #24028, which is open.
Among the queued p2 bugs, this card (09:06Z) is the oldest; cli: os start with OS_MCP_STDIO_ENABLED spawns serve with stdio inherited and no config positional, so oclif reads the MCP client's first stdin line (initialize) as the config path; the boot exits 1 and initialize is never answered #24002 is 17:26Z and runtime(dispatcher): PUT and PATCH routes skip the observability Proxy, so they answer with no X-Request-Id and lose the 5xx error capture; only get/post/delete are wrapped #24025 is 19:13Z.
Its serve.ts region was held by seat 1's cli/serve: --no-server --preset minimal prints the ready banner ending "Press Ctrl+C to stop" and then exits 0 on its own about 40 ms later, removing the runtime state file it had just written #23744, which landed as bb14934cda (seat 1's claim 6223166612 records it). Seat 1 takes p3 cards only, by the maintainer's word to that seat.
File surface (read on origin/main c91af8ed6; stop on a breach and explain it in the report). Seat ruling A on PR fix(cli,runtime): refuse an uncreatable state, output or cache directory at once instead of looping in recursive mkdir #23979's open question (6219392523) stands: one module-internal makeDirectorySync per package, no new export.
packages/cli/src/commands/serve.ts :1097: fs.mkdirSync(path.dirname(runtimeFile), { recursive: true }), the state file's directory. It goes through packages/cli/src/utils/make-directory.ts' bounded walk. An uncreatable parent then refuses at once, naming the directory, as PR fix(cli,runtime): refuse an uncreatable state, output or cache directory at once instead of looping in recursive mkdir #23979's doors do, instead of hanging. Only this call site and the refusal it raises change.
Folds, behaviour-preserving:
- packages/runtime/src/standalone-stack.ts makeSqliteDatabaseDirectory (:753) folds onto packages/runtime/src/make-directory.ts;
- packages/cli/src/commands/dev.ts prepareDevDatabaseDirectory (:117) folds onto packages/cli/src/utils/make-directory.ts.
- Each keeps its callers, its answers and its errors. If a fold cannot keep them byte for byte, say why and keep the copy.
Pins: the serve state-file door refused under an uncreatable parent (the shape of PR fix(cli,runtime): refuse an uncreatable state, output or cache directory at once instead of looping in recursive mkdir #23979's uncreatable-directory-doors.integration.test.ts), plus the two folds' existing tests staying green.
One .changeset/23858-*.md (patch for each package whose shipped behaviour changes).
⛔ Hold-offs:
- sqliteFilenameFromUrl and the rest of standalone-stack.ts;
- start.ts and the doors PR fix(cli,runtime): refuse an uncreatable state, output or cache directory at once instead of looping in recursive mkdir #23979 already covered;
- no new export from either package.
  Container & model: S-to-M (one call site, two folds, a door pin), mode:subagent, model: TIER_DEFAULT (dispatch-gates --tier: no path-derived mandate)
  Clause-②: no
  Basis for the Clause-② line: a hang becomes a refusal for a directory that cannot be created. Nothing that worked stops working, and no export, flag or accepted input changes.
  Responsibility: the CLI's and runtime's directory creation (this lane) | Node's recursive mkdir, which loops under some uncreatable parents (the card's measurement) | an operator whose os serve state directory cannot be created and who gets a hang instead of a refusal
  Thread-read: 6220529082
  Serial constraints cleared: open PRs read in this act.
No open PR touches serve.ts, dev.ts, standalone-stack.ts or either make-directory.ts.
No pm:dispatched claim names them.

Measured at the public door: OS_HOME=/proc/os-23858-r2 OS_DATABASE_URL=:memory: os serve hung on base after the bind (794,594 failing mkdir in 20 s, no banner), and os dev --database :memory: hung the same way in its serve child (1,392,733 in 40 s); on head both print the banner (4.7 s and 13.2 s) with 1 failing mkdir. os start never reaches this write: it refuses at HOME_DIR/data first (PR #23979's door), unchanged. The two folds were NOT made, by the claim's own rule: measured function by function, a fold onto makeDirectorySync keeps answers and error text on 5 of 7 input classes but changes them for a dangling symlink (as the directory: the copy returns, the fold refuses EEXIST; mid-path: ENOENT at the deeper level becomes EEXIST at the link), and the copies' async walk yields 1 to 100 event-loop turns where the fold yields 0. So dev.ts and standalone-stack.ts are not in the diff; the measured cost of the copies' answer and a recommendation are in open_questions. PR line 1 is Fixes #23858 as dispatched; if the seat takes the fold onto this family card, line 1 becomes Part of #23858 (seat writes).

Seat rulings on round 2's report (PR #24088; claim 6226232050) · domain:cli seat 2 · session session_018t6a5rvqPRvEDMCVVW9kYT · 2026-10-17T00:33Z

1. The folds: none in this PR (option C for this card).

The claim's own rule applied: "If a fold cannot keep them byte for byte, say why and keep the copy."
The dev measured that a fold changes the answer for a dangling symlink in the database directory's path, in both packages. It also changes the async walk's yield.
So dev.ts and standalone-stack.ts keep their copies, and PR fix(cli): os serve no longer hangs on a runtime state file directory that can never be made #24088 keeps Fixes #23858: the card's state-file remainder is what it closes.
The dangling-symlink answer is a measured defect at two public doors. This seat files it as its own card, carrying the dev's recommended option A.

2. The pending round-1 changeset: ruling B, as on #24042 (6226688716).

PR fix(cli): os serve no longer hangs on a runtime state file directory that can never be made #24088 restores .changeset/23858-uncreatable-directory-refusal.md byte-for-byte from the merge base. The finding: random changeset filenames collide silently across parallel agents — a round overwrote a sibling PR's minor changeset and every gate stayed green #17712 guard holds Check Changeset red on any edit of a pending changeset until a person confirms, and a seat cannot confirm.
The new .changeset/23858-serve-state-file-directory.md says that it covers the runtime state file the round-1 note named as not covered yet.
The PR's Acceptance notes name that superseded line for the release owner (carrier: the release owner, at changeset version time).

3. The silent best-effort catch (serve.ts :1113) is outside this card, by the dispatch. This seat files it as its own card, from the dev's out-of-scope finding 1.

"summary": "Round 3, seat ruling B (6227399342), on the same branch, no new claim, no rebase, no force-push. Commit c31899a (pushed; PR head is c31899a): (1) .changeset/23858-uncreatable-directory-refusal.md restored from the merge base 8133cc7: blob 372ecd0bd09b == merge-base blob, git diff 8133cc780 HEAD -- .changeset/23858-uncreatable-directory-refusal.md 0 bytes, so the file is no longer in the PR's diff and its 'Not covered yet' line is back. (2) .changeset/23858-serve-state-file-directory.md gains one sentence, after its Clause-② line: 'This covers the runtime state file that the entry fix(cli,runtime): a state, output or cache directory that can never be made is refused at once, naming the path and the operating system's code, instead of hanging lists as Not covered yet.' It names that entry by its exact title (1 hit in the restored note), so the compiled CHANGELOG locates it without a tracker number. Nothing else changed: git diff fd250408f HEAD -- . ':!.changeset' is 0 bytes. The PR body was not edited. Three of its passages are now stale and are named for the seat in deviations, with the Acceptance-notes replacement verbatim.",
"tests": "No code or test file changed this round: git diff fd250408f HEAD -- . ':!.changeset' is 0 bytes, so round 2's readings on fd25040 stand: CLI unit tier exit 0 (308 files, 4,582 tests); the door pin plus serve-runtime-state-project-key (integration) exit 0 (2 files, 18 tests); the runtime walk tests exit 0 (2 files, 12 tests); both typechecks exit 0; the ablation of the serve.ts call site went red at the bound and was restored and proven. Round 3's own reading: grep -c of the cited entry title gives 1 hit in each of the two changesets.",

ACCEPT: 6227680153 on PR fix(cli): os serve no longer hangs on a runtime state file directory that can never be made #24088. Every check on the head is green or a roster skip, and landing is armed in this act.
Rulings: 6227399342. No folds, by the claim's keep-the-copy rule. Ruling B on the round-1 changeset.
Filed from it: cli/runtime: a dangling symlink in the SQLite database directory's path fails os dev and os serve late, with a plugin-start error that names neither the file nor the directory (the two bounded-walk copies accept any EEXIST) #24090 (the dangling-symlink class; the fold rides it) and cli/serve: when the runtime state file cannot be written, os serve still prints "Press Ctrl+C to stop" and says nothing; a supervisor then gets ENOENT on runtime.<env>.<project>.json (writeRuntimeState's catch is silent) #24091 (the silent state-file catch).

Review chain: rulings 6227399342, ACCEPT 6227680153, card pointer 6227689596. Round 1 was PR fix(cli,runtime): refuse an uncreatable state, output or cache directory at once instead of looping in recursive mkdir #23979 (2e1562091c, Release 6219973785).
What landed: os serve no longer hangs after binding its port when its runtime state file's directory can never be made, as under an OS_HOME beneath /proc. The bounded walk refuses that directory at once, and the boot goes on to its banner. os dev's serve child is fixed the same way.
