ObservationRegistry stores file versions and completeness. Native and legacy reads record observations only when pre-read and post-read versions match. Partial, clipped, truncated, or lossy reads are marked incomplete. |
Enforce guarded write rules src/core/tools/guardedWrite.ts, src/core/tools/__tests__/guardedWrite.spec.ts |
guardedWrite applies create, edit, and version-check rules from observations. Writes to the same resolved path run in FIFO order, check cancellation, publish under a shared lock, and refresh observations when a version is available. |
Atomic file writes and JSON integration

|---|---|
Stage and publish files atomically src/services/file-safety/safeWriteText.ts, src/services/file-safety/__tests__/safeWriteText.spec.ts |
safeWriteText stages and syncs content before rename. It supports backup and rollback, preserves target permissions, resolves symlinks, and handles platform-specific durability and DACL operations. |
Use resolved targets for JSON writes src/utils/safeWriteJson.ts, src/utils/__tests__/safeWriteJson.test.ts, src/utils/__tests__/safeWriteJson.lockKey.spec.ts, src/eslint-suppressions.json |
safeWriteJson locks and merges against resolved paths, stages JSON beside the publish target, and delegates publication and rollback to safeWriteText. The suppression counts for two rules decrease. |

Merge Risk: 🟡 Moderate · up to bce5c
On filesystems where directory fsync is unsupported, writes can report failure after publishing new content, and backup-mode writes can leave old-content files behind. This is environment-dependent but should be resolved or explicitly accepted before merging.
Security Architecture Review
Security architecture risk: 🟡 Moderate · up to bce5c
A filesystem error can occur after saved permissions have changed, while previously allowed actions remain authorized in memory until a refresh. This conditional risk requires existing authorization and a publication failure; no new remote access or privilege escalation was demonstrated.
Retained concerns
- Medium · security · inferred: The newly introduced committed-but-rejected JSON outcome is not reconciled by MCP permission updates. A POSIX directory-sync failure can occur after the configuration rename; the rejection skips live tool-permission refresh while programmatic-update suppression can discard watcher events. Removing an existing alwaysAllow grant can therefore leave the prior in-memory grant available to automatic approval until another refresh. This requires an existing grant, enabled MCP automatic approval, and the filesystem failure; actual tool execution under this condition was not demonstrated.
Security review details
Security Blast Radius
- inferred — The material exposure is local filesystem state and authorization derived from configuration written through the shared JSON utility. MCP updates can affect global or project configuration; task-history persistence also inherits the changed failure contract. The available evidence does not establish cross-tenant exposure or additional operating-system privileges.
Security Findings and Attack Paths
- inferred — A model-requested MCP tool could remain eligible for automatic approval after a saved grant removal if directory synchronization fails after commit and the live permission refresh is skipped. The approval decision consults the supplied server-tool flags and additionally requires global MCP automatic approval. No evidence establishes attacker control of the filesystem failure or demonstrates execution through this conditional path.
Trust Boundaries and Controls
- observed — Read observations follow ignore checks and user approval. Within the new guard, observations authorize mutation scope and detect stale versions; they are not a replacement for path-access authorization or protection against non-cooperating filesystem writers. Existing model-write publication remains outside this new guard boundary.
Resilience and Maintainability Implications
- observed — With backup mode enabled, a post-commit directory-sync failure leaves new content at the destination and old content at a backup path, because backup deletion is success-only and rollback is pre-commit-only. JSON cleanup does not remove that backup. Backup retention after an unlink failure already existed at the base; this PR adds another retention path without establishing broader read permissions.
Hardening Proposals
- proposed — Handle committed-but-not-durable outcomes explicitly at security-sensitive callers: reconcile live permissions with the published configuration or suspend automatic approval until reconciliation completes. Give retained backups explicit cleanup and recovery ownership without rolling old content over an already committed update.

Full details: Regression Evidence
Explanation
A queued-write cancellation transition lacks focused coverage. guardedWrite adds a per-path queue and checks the mutable task.abort only when the queued callback runs (src/core/tools/guardedWrite.ts:322-333); its later checks also read the same flag (:350-356). Task.resumeAfterDelegation() resets that flag to false (src/core/task/Task.ts:3455-3464). The tests cover an abort that remains true at dequeue and an abort while waiting for the lock (src/core/tools/__tests__/guardedWrite.spec.ts:767-812), but not abort followed by resume before dequeue. In that sequence, the queued callback sees false and can publish. This is a concrete cancellation branch introduced by the new queue behavior, and the current tests do not exercise it.
Resolution
Add a guardedWrite.spec.ts regression test that holds an earlier same-path write pending, queues another write, aborts and resumes the task before the second write dequeues, and asserts that the second write does not publish. Preserve cancellation across resume with an immutable cancellation generation/token captured when the write is queued, and reject if that generation changes before publication.
Full details: Security Boundaries
Explanation
guardedWrite trusts the supplied path and can write outside the task workspace without an access check. src/core/tools/guardedWrite.ts:284-318 resolves relPathOrAbsolute but does not validate workspace containment, RooIgnore access, write protection, or user approval. For an absent target, lines 369-383 route an unobserved path to createIfAbsent, which publishes it. A caller that passes a model-supplied ../../outside/new-file or absolute path can therefore create a file outside the workspace without the controls used by WriteToFileTool (src/core/tools/WriteToFileTool.ts:50-58, 88-97, 130-136). The new function has no in-tree production caller yet, but it is exported as a write entry point and performs the unchecked write when called.
Resolution
Validate the resolved target against the permitted workspace and RooIgnore/write-protection rules before any filesystem operation. Require the caller to complete the appropriate user approval before publishing, or enforce approval through the API. Add tests showing that traversal and absolute paths outside permitted roots are rejected and that rejected paths never publish.
Full details: Lifecycle Resource Cleanup
Explanation
A queued guarded write can run after cancellation when the task resumes. The new enqueue chain waits for earlier writes (src/core/tools/guardedWrite.ts:75-78), then the callback checks the mutable task.abort flag at dequeue (:322-333) and again through () => task.abort under the publish lock (:350-355, :380-392). Task.abortTask() sets that flag to true (src/core/task/Task.ts:3261-3268), but resumeAfterDelegation() resets it to false on the same task (:3455-3464). Thus, if a write waits in the chain during abort and the task resumes before that write dequeues, both checks see false and the old write can publish. The added tests check an already-aborted task and aborts during lock/preflight, but not abort followed by resume while a write is queued (guardedWrite.spec.ts:767-811).
Resolution
Associate queued writes with an immutable task-run cancellation token or generation captured when enqueued, and reject the write if that token changes before publication. Increment the generation on abort and resume so a resumed task cannot authorize writes from its previous run. Add a regression test that queues a write behind a blocked same-path write, aborts and resumes the task, then verifies the queued write rejects without publishing.

…ve (U1, issue 1375) Split unit U1 of PR 1833. Three changes, each with a test that fails without it: - a caller-supplied staging path is checked for location and file type before anything is written, so an arbitrary path or a symlink cannot be published onto the target; - a failed parent-directory fsync on POSIX is reported as PostCommitDurabilityError instead of being swallowed, so a successful return never claims durability the filesystem did not grant; - the staged file and this write's own staging directory are released before RollbackFailureError is thrown. Focused coverage for resolveLockKey added: canonical parent directory, a dangling-link chain, and termination at the bounded depth on a two-link cycle.

…ishTarget (U1, issue 1375) The resolver may fall back to the given path only when lstat also reports the path as absent. An EACCES or EIO failure says nothing about whether the path is a link, so falling back would publish through a link we were not allowed to inspect. Focused tests added for both branches.

compile failed at the unit head on three points:
- RollbackFailureError needs a string backupPath, but the throw now happens after cleanup, so the
`string | null` narrowing was lost. The failure is now held as { error, backupPath }.
- The async lstat stand-in is built on the Stats prototype so it satisfies fsSync.Stats.
- The realpath/readlink mocks are typed to the real signatures; the readlink mock answers once
because only the link path is read.

The any usage this entry covered is gone in the rewritten file, so the count drops 4 -> 3. eslint --prune-suppressions --max-warnings=0 confirms it.
The read tools record the observed on-disk version through task.observationRegistry, but the field was only declared in a later unit, so at this head the call dereferences undefined and the mocked e2e run fails on the read_file smoke tests. The registry is introduced by this unit, so the field belongs here. tsc clean on this unit, 11 observationRegistry tests pass, ESLint --max-warnings=0 clean.
The two any usages this entry covered are gone in the rewritten spec, so the count drops 98 -> 96. eslint --prune-suppressions --max-warnings=0 confirms it.

safeWriteJson rethrows RollbackFailureError and the telemetry callers record only error.message, so the generic wrapper message lost the filesystem errno text of the publish failure. Include the publish error message while keeping the rollback context (publishError, rollbackError, backupPath) unchanged. Tests: 52 passed in safeWriteText.spec.ts, ESLint clean with --max-warnings=0.
…the Actions queue, no source change
The dump path was the fixed sibling <target>.acl.tmp. A pre-existing user file at that path is unlinked by the failed-save branch and by both cleanup paths, and two concurrent writes to the same target share one dump, so one write can restore or delete the other's. Use the per-write unique name like the staging file. Tests: 52 passed in safeWriteText.spec.ts, ESLint clean with --max-warnings=0.

… the test title The committed guard only exists for backup mode, but the post-commit fsync test ran without backup, so removing the guard would not fail any test. Added the backup:true case asserting that the backup is not renamed back over the committed content. The safeWriteJson test title said the original error is re-thrown while the assertions require RollbackFailureError with the publish failure as cause; the title and the stale comment now match the assertions. Tests: 51 passed in safeWriteText.spec.ts, 23 passed 1 skipped in safeWriteJson.test.ts, ESLint clean with --max-warnings=0 on both.

This unit's copy of ApplyPatchTool still recorded complete: true when the model had no prior observation, which is the behaviour already fixed on Zoo-Code-Org#1910/Zoo-Code-Org#1911/Zoo-Code-Org#1912/Zoo-Code-Org#1913/Zoo-Code-Org#1914 and on Zoo-Code-Org#1915: the tool's own hunk read is not a model read, so it cannot grant authority for a later full-file replacement. Tests updated to match, including the move case where the completeness flag is now false. Local note: this spec cannot run in this worktree (the 'diff' package is not resolvable from either node_modules here) and ESLint cannot resolve its config here; CI covers both.

Split unit U5 of #1833, under the plan on this issue (5993969784 / 5994039786 / 5994053776). Base is U3 (#1913) per the merge order.
Scope (one gate scope): the guard core —
createIfAbsent,replaceIfVersion, the cancellation re-check before publication, and the model-facing path on a rejection.Content source of record:
kind: commit, base7c291bb08→ head6768ccfaf, replayed on the current main tip9af61f87eso this branch carries nothing that main already has.Budget (own delta, not the stacked view): 1277 a+d / 418 changed executable lines. 1277 a+d is above the 1000 hard cap — documented deviation:
guardedWrite.tsis a new file and its spec tests that file as a unit, so the file and its tests cannot be separated without breaking the fidelity contract.Verification at this head: 47 passed; ESLint
--max-warnings=0clean on every file in the unit; Prettier clean;src/eslint-suppressions.jsonnever increased.The GitHub view also carries the unmerged base, so the numbers above are this unit's own delta.
