feat(tools): publish apply_patch through the guard (U6, #1375)

[easonLiangWorldedtech]

This PR routes the apply_patch tool through the guard, so a patch hunk can no longer "write" a file the model never fully read: an unobserved overwrite and a stale version token are refused with the standard remediation. A move carries the source's completeness to its destination instead of claiming completeness for lines the model never read, and a partial-source move onto an already-observed destination is rejected before any state changes. It also fixes a resource leak: when the guard refuses a publish, saveDirectly now rolls back the parent directories it created.

It is the sixth of nine PRs for epic #1375 (chain tracked on #1991).

Closes: #2021 (this unit's tracking issue).
Refs: #1991 (chain tracking), #1375 (epic).

Description

What this PR changes:

1. apply_patch publishes via guardedWrite, so an unobserved overwrite and a stale version token are rejected with the read-first / re-read-then-retry remediation instead of clobbering the file.
2. A move re-targets the source's observation onto the destination: the destination inherits the source's complete flag, so a slice, range, truncated, or indentation-block source never authorizes a full-file replacement at the new path.
3. A partial-source move onto a destination that was already observed completely is rejected before any file or registry state is touched.
4. saveDirectly captures the list createDirectoriesForFile returns and, if the guard rejects, removes those directories innermost-first with rmdir (which refuses a directory another writer populated, so the loop stops at the first failure) and rethrows the original write error.
5. Ancestor-identity pinning at publish: the confined write records the identities of the directories it created and re-checks them before the commit rename, refusing with AncestorReplacedError if an ancestor was swapped underneath it.

Why the diff looks bigger than the change: the chain is non-cumulative - this branch is based on main and carries its own copy of the earlier units' content, which the GitHub diff shows as context.

Review focus: src/core/tools/ApplyPatchTool.ts, the guard wiring in src/core/tools/guardedWrite.ts, the rollback path in src/integrations/editor/DiffViewProvider.ts, and the specs named below.

Test Procedure

From the repository root, with dependencies installed:

pnpm --dir src exec vitest run --globals core/tools/__tests__/applyPatchTool.guardedWrite.spec.ts
pnpm --dir src exec vitest run --globals integrations/editor/__tests__/DiffViewProvider.spec.ts
pnpm --dir src exec tsc --noEmit
pnpm --dir src exec eslint --max-warnings=0 core/tools/ApplyPatchTool.ts core/tools/guardedWrite.ts integrations/editor/DiffViewProvider.ts

Environment: Node 22+, Linux/macOS/Windows CI runners (the guard's platform-specific branches are exercised through the injected platform option, not a real Windows host).

Pre-Submission Checklist

• Scope is one gate scope and matches the unit.
• No .changeset or CHANGELOG changes (AGENTS.md).
• src/eslint-suppressions.json unchanged - no suppression count increased.
• New code lints clean (--max-warnings=0) rather than relying on suppressions.
• Tests added at the lowest layer that would have caught each finding.
• Visual Snapshot item considered: not applicable (no rendered surface).

Visual Snapshots

Not applicable - no UI change.

Videos (interaction / animation only)

Not applicable.

Documentation Updates

None. No user-facing setting, command, or documented behavior string changes; the guard's remediation text is already introduced in earlier units. No .changeset and no CHANGELOG edit (AGENTS.md).

Additional Notes

• Budget: 691 a+d / 105 changed executable lines - inside both caps.
• mutation-diff is red on the changed-line budget only: the gate counts the GitHub diff, which carries the unlanded predecessors (1205 changed executable lines against the 500 cap; this unit's own delta is 105). The row clears when the predecessors land and this branch is rebased.
• The directory-rollback test is a real pin: with the DiffViewProvider.ts change stashed it fails.
• Content source of record: the superseded umbrella PR feat(tools): track read completeness and guard the diff-view save path (S4b, #1375) #1833 (closed), replayed onto the current main tip. Split plan of record: comments 5993969784 / 5994039786 / 5994053776 on [Tracking] guarded-write chain (epic 1375): rules, port sources, chain-level rows #1991.
• Merge order for the chain: U1 -> U2 -> U3 -> U4 -> U5 -> U8 -> U6 -> U7 -> U9. This unit's merge-order predecessor is U8 (feat(editor): route the diff-view save through the guard (U8, #1375) #1916).

Verification at this head

• Local lanes at this head: integrations + core/tools + activate - 1340 passed / 17 skipped across 60 files; tsc --noEmit clean; eslint clean on the changed files with no suppression-count increase.
• CI at this head: all required checks green; mutation-diff red on the budget-cap count described above (no surviving mutants in this unit's own lines).

Updated this round

• Rewrote the description for human reviewers (maintainer feedback on feat(file-safety): atomic text publish primitive (U1, #1375) #1910) and linked this unit's tracking issue Tracking fws U6: apply_patch publishes through the guard #2021, so the PR now has a linked issue.

Get in Touch

Reviewer and maintainer questions are welcome as comments on this PR or on #1991.

Stryker directive removal (equivalence notes)

Per AGENTS.md the two Stryker suppression comments in the guarded save
path were removed instead of kept; their equivalence claims:

• writeKind default StringLiteral ("update" -> ""): an empty kind
  dispatches exactly like "update" inside guardedWrite - only "edit"
  and "create" branch distinctly - and the default-parameter line is
  not part of this unit's changed-line selector, so the mutant is
  equivalent / out of scope.
• saveTask operand of the adoption-probe guard (LogicalOperator):
  GuardRejectedError is only thrown by guardedWrite, which is reached
  only after the !saveTask check above has already thrown. Whenever
  the operand is evaluated saveTask is provably non-null, so dropping
  the operand cannot change which branch is taken.

mutation-diff remains advisory for stacked units; maintainers decide any
narrow gate-config exclusion.

📝 Summary

Summary by CodeRabbit

• New Features
  • File writes are checked against versions captured during reads, helping prevent accidental overwrites of intervening changes.
  • Reads distinguish complete files from partial views; edits requiring a full view are rejected when only part of a file was read.
  • File publishing uses staged writes, preserves existing permissions, and supports backups.
  • JSON writes can be restricted to a specified directory.
  • Read results report clipped lines separately from omitted lines.
• Bug Fixes
  • Symlink writes, changed paths, and failed writes receive additional safeguards and cleanup.
  • Editor-based saves use file-version checks and guarded publishing.

The change adds per-task file observations and guarded writes. Read paths record stable file versions and view completeness. Patch, diff, and editor saves select write guards. Text and JSON publishing add target resolution, staging, confinement checks, locking, and cleanup.

Changes: Observed reads and guarded writes

Layer / File(s)	Summary
File observations and read completeness src/core/task/Task.ts, src/core/task/observationRegistry.ts, src/core/tools/ReadFileTool.ts, src/core/tools/ApplyDiffTool.ts, src/core/tools/ApplyPatchTool.ts, src/integrations/misc/indentation-reader.ts, src/core/tools/__tests__/*, src/integrations/misc/__tests__/*	Each task owns an ObservationRegistry for path versions and completeness. Stable reads record observations. Read scope reflects clipping, truncation, offsets, indentation reads, and lossy decoding.
Guard checks and serialized publication src/core/tools/guardedWrite.ts, src/core/tools/__tests__/guardedWrite.spec.ts	guardedWrite supports create, update, and edit operations. It serializes writes by path, checks absence or version under a resolved-path lock, and refreshes observations after publication.
Patch, diff, and editor write paths src/core/tools/ApplyPatchTool.ts, src/core/tools/ApplyDiffTool.ts, src/integrations/editor/DiffViewProvider.ts, src/core/tools/__tests__/*, src/integrations/editor/__tests__/DiffViewProvider.spec.ts	Patch and diff operations pass explicit write kinds and move completeness. DiffViewProvider publishes through guardedWrite and coordinates rejection cleanup and teardown.
Text staging, commit, and cleanup src/services/file-safety/safeWriteText.ts, src/services/file-safety/__tests__/*	safeWriteText resolves publish targets, validates staging files and target identities, stages and flushes content, and handles backups, commits, platform metadata, and cleanup.
Confined JSON writes and resolved-target locking src/utils/safeWriteJson.ts, src/utils/__tests__/safeWriteJson*.spec.ts, src/eslint-suppressions.json	safeWriteJson adds optional path confinement and resolved-target locking. It checks containment before and under the lock, then delegates staging and commit to safeWriteText. Tests cover symlinks, target movement, commit failures, and cleanup.

Loading

Merge Risk: 🔵 Low · up to c411f

The publishing behavior is unchanged by the latest edit, but the PR still exposes a per-user device identifier in repository history. Remove it before merging or explicitly accept that bounded privacy risk.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 5a0dd

The change improves protection against stale and partial-file overwrites. However, replacing an existing file can weaken Windows access restrictions when permission restoration fails. Some move operations also retain their existing non-atomic behavior.

Retained concerns

• Medium · security · inferred: Existing-file direct tool writes now replace the file instead of updating it in place. On Windows, publication precedes DACL restoration, and failures saving or restoring the original DACL are swallowed. Where the replacement has broader permissions than the original, an approved content edit can therefore expose the file to additional readers or writers, temporarily or persistently. Successful restoration mitigates the persistent case but does not make access-control preservation a publication precondition.

Security review details

Security Blast Radius

• inferred — The inspected exposure is host filesystem content published with the extension process's existing authority. The Windows concern affects individual rewritten files whose original DACL is more restrictive than the replacement's permissions; additional principals may gain read or write access without receiving elevated process privileges.

Security Findings and Attack Paths

• inferred — A legitimate approved write to a Windows file with a restrictive explicit DACL reaches replacement publication. If saving or restoring that DACL fails, the write still succeeds. A principal permitted by the replacement's broader permissions can then read or modify content previously restricted by the original DACL. The failure behavior is demonstrated by mocked tests; deployment-specific permission widening was not reproduced.

Trust Boundaries and Controls

• observed — Observation authority is task-scoped and separates content completeness from filesystem version identity. The guard checks cancellation after queueing and under the lock, rejects stale versions, and retains partial completeness after targeted edits.
• observed — Publication deliberately follows existing symlink referents and rejects dangling links. Move containment is lexical, while ignore matching resolves referents but allows outside-directory paths or errors. Tool writes already followed symlinks at the base, so this is not established as a new tool escape. JSON writes now follow referents instead of replacing links; production-path attacker control remains unresolved.

Resilience and Maintainability Implications

• observed — Rejected editor saves use discard-only recovery rather than writing the original preview back over newer disk content. Placeholder removal checks its captured version under the shared lock, and overlapping teardown operations are serialized. Successful publication clears an unchanged dirty buffer by reloading from disk rather than performing another unguarded save.
• observed — Move destination publication and source deletion remain separate operations. Source deletion has no version check and its failure is logged rather than propagated; the non-focus move branch still uses raw destination writes. Comparison with the base confirms these lifecycle limitations predate the PR, so they are not retained as newly introduced concerns.

Hardening Proposals

• proposed — Make preservation of an existing Windows DACL a publication precondition: prepare and verify equivalent restrictions on the replacement before making it visible, and reject the write when preservation cannot be established.
• proposed — Document the resolved-target authorization policy for tool and persistence writes, then test outside-workspace referents and referent changes. Treat source-version-protected move cleanup and consistent guarding across execution modes as follow-up work for the existing lifecycle gaps.

Full details: Regression Evidence

Explanation

The changed Task behavior lacks focused coverage at the Task layer. Task.ts:288 initializes readonly observationRegistry = new ObservationRegistry(), but src/core/task/__tests__/Task.spec.ts has no registry assertion. The standalone observationRegistry.spec.ts tests only ObservationRegistry, while tool and editor tests inject registry instances. Those tests would pass if the Task initializer were removed.

Resolution

Add a focused test in src/core/task/__tests__/Task.spec.ts that constructs a Task, asserts task.observationRegistry is an ObservationRegistry, and constructs two Tasks to assert their registries are distinct. Keep the standalone registry behavior tests.

Full details: Security Boundaries

Explanation

The PR adds .local/state/gh/device-id with the persistent UUID 2909d201-4884-42a8-ad5f-7908190cd7d6. The base ref lacks this file, the head ref contains it, and no ignore rule covers the path. A clone, fork, or review therefore exposes a unique local GitHub device identifier. This is a concrete PII leak introduced by the PR.

Full details: Lifecycle Resource Cleanup

Explanation

The changed DiffViewProvider.revertChanges() path still allows duplicate teardown work. runTeardown() clears teardownInFlight at lines 1108-1110 before revertChanges() awaits restorePreviewTabs() at lines 972-974. That restoration awaits showTextDocument() at lines 1347-1357. If a second cancellation or Task.disposeOnce() call arrives during that await, relPath and activeDiffEditor remain set, so the second caller starts another teardown at line 910. It can repeat document revert, diff-tab cleanup, preview restoration, and finalization work.

Resolution

Keep teardown ownership active through preview restoration and session finalization. Use one shared teardown promise or explicit owner state that covers document cleanup, restorePreviewTabs(), and reset(). Make cancellation and disposal callers join that ownership, and clear it only after all cleanup and finalization steps complete.

[easonLiangWorldedtech]

Confirmed — this is the same defect as the other three fsync threads, not four separate ones.

The rollback in the catch ran whenever backup mode had renamed target -> backup, including when the failure happened after the commit rename had already published. PostCommitDurabilityError tells the caller the content is at the target path, but the catch had already renamed the backup back over that target, so the error message and the file disagreed.

Fixed in the unit that owns the publish path, #1910, commit 58f803ddb: a committed flag is set immediately after the commit rename and the rollback is skipped once it is set, so only a pre-commit failure can restore the backup.

Regression test at the lowest layer that would have failed (commit rename succeeds, post-commit directory open fails, backup mode on): fails without the guard, passes with it. This unit carries the same copy of safeWriteText.ts, so it inherits the fix once #1910 merges first in the chain order U1 -> U2 -> U3 -> U4 -> U5 -> U8 -> U6 -> U7 -> U9.

Resolving as handled.

[easonLiangWorldedtech]

Partly valid, but outside this unit's scope. The else branch is pre-existing main behaviour: the guarded publish is gated by the PREVENT_FOCUS_DISRUPTION experiment by design, and this unit's stated scope is the guarded path. Routing the experiment-off path through guardedWrite is a behaviour change for users with the experiment off, so it is not a fix this unit can make on its own. Recorded as a follow-up on the tracking issue so the gap is not lost: with the experiment off, an apply_patch move writes the destination with plain fs.writeFile and no completeness check.

499-500: The experiment-off move still writes the destination without the guard.

The enabled path now publishes through guardedWrite(..., "create", sourceComplete). The else branch at Line 506 still writes moveAbsolutePath with plain fs.writeFile, and it runs no partial-source check. A previous review reported this issue. The author recorded it as a follow-up outside this unit's scope.

Replace the as any casts in the changed test blocks with typed casts.

The changed blocks add explicit any casts. Use bracket access for private members and unknown-based structural casts for VS Code test doubles. This follows the project requirement that new code introduce no any.

+				diffViewProvider["editType"] = "modify"
-				expect((diffViewProvider as any).preEditScrollLine).toBe(42)

Apply the same typed pattern to the remaining casts in the preEditScrollLine capture and restore block.

Check the content of the single console.error call, not only the call count.

The test title says that the safety net must not log a cleanup error. toHaveBeenCalledTimes(1) cannot tell which message was logged. Suppose a regression stops logging the commit failure and logs the ENOENT cleanup error instead. The count is still 1, and the test still passes. The path instructions require a return-value or content assertion when a test asserts only mock call counts.

Assert that the single call reports the original failure, and that no call reports a cleanup failure.
