Record ignored paths for checkpoints src/services/checkpoints/ShadowCheckpointService.ts, src/services/checkpoints/__tests__/ShadowCheckpointService.spec.ts |
Initialization and saved checkpoints record ignored paths. Record writes use atomic temporary-file replacement. Marked checkpoints require valid records, and failed publication preserves prior records. |
Validate commits and clean up on restore src/services/checkpoints/ShadowCheckpointService.ts, src/services/checkpoints/__tests__/ShadowCheckpointService.spec.ts |
Restore rejects invalid hashes and non-commit objects. Marked checkpoints preserve paths ignored at checkpoint time or under current rules, remove other untracked paths, and prune empty directories. Legacy checkpoints retain prior cleanup behavior. Tests cover malformed records, changed ignore rules, legacy records, failed cleanup, and metadata failures. |
Estimated code review effort: 3 (Moderate) | ~25 minutes
Change: Bug fix · Severity of issue fixed: Medium
Merge Risk: 
578e4
-
Checkpoint restore has no established production defect remaining here. Strengthen the cleanup-failure test so it protects the intended behavior; this does not block merging.
Security architecture risk: 
56e00
-
The change addresses a real data-loss case, but a failed or interrupted metadata write can leave a new checkpoint unable to protect the files it was meant to preserve. Repeated saves can also expand which files survive a later restore.
Retained concerns
- Medium · reliability · inferred: A failed or interrupted record write can leave a newly saved checkpoint with missing or incomplete protection metadata. Restore can then delete files that were ignored when the checkpoint was saved.
- Medium · security · inferred: A save that creates no commit still adds the current ignored paths to the previous commit’s record. Files first ignored after that commit can therefore survive a later restore to it.
Security review details
-
Security Blast Radius
- inferred — The affected asset is the active workspace: an incorrect record can alter which untracked files survive restore, while an incomplete record can leave files exposed to cleanup. No new cross-service dependency is shown.
Security Findings and Attack Paths
- inferred — Because a no-op save can enlarge an older commit’s record, a path made ignored after that commit can later be exempted from cleanup if ignore rules change again. This is a persistence consequence of the stated same-hash merge policy, not evidence of an independently verified exploit.
Trust Boundaries and Controls
- observed — The user-facing restore flow parses a restore payload before forwarding it, but the inspected service and core wrapper do not themselves establish that the commit hash belongs to the current task. The payload schema’s hash restrictions were not established.
Resilience and Maintainability Implications
- inferred — The record is not persisted atomically with its commit: errors are suppressed, direct rewrites can leave incomplete content, and restore can remove files before a subsequent reset fails.
Hardening Proposals
- proposed — Make record publication atomic, distinguish failed recording from a genuinely old checkpoint, and keep each record’s contents tied to the intended checkpoint observation.

Explanation
The changed checkpoint service and tests remain connected to issue
#1832. Hash validation, metadata validation, atomic record handling, cleanup failure handling, and legacy behavior protect checkpoint restore. No unrelated implementation change is shown.
Full details: Security Boundaries
-
Explanation
No changed path meets the security failure conditions.
restoreCheckpointnow restricts hashes to lowercase 40- or 64-character hexadecimal values and passes them as argument values to Git. Ignore metadata contains path strings only; the code does not execute them or expose file contents. Cleanup operates on paths returned by Git and uses filesystem APIs. The changed callers do not bypass an approval or allowlist control.
Full details: Description check
-
Explanation
The description is thorough and follows the template. It links issue
#1832with "Closes:#1832", explains the root cause (git clean -f -d -f ran with current ignore rules before git reset --hard), and describes the implementation (per-commit ignored-path records, restore logic, legacy fallback). It gives a test procedure with the exact commands and the specific tests, reports results, and states that no documentation or UI changes apply. The checklist is filled in. Minor gaps: the Discord username under "Get in Touch" is missing, the Visual Snapshots and Videos sections are marked not applicable, and the description uses some non-STE phrasing (for example, "the clean applied", "Repeated saves ... add to the record rather than replace it" is fine, but sentences like "Fully ignored directories ... collapse to one entry" and the parenthetical "(also via the commit hook)" are long). The writing style is mostly close to the ASD-STE100 guidance but not strictly compliant, and the template asks for it. These gaps do not make the description incomplete.

Explanation
Issue
#1832requires rollback to use both snapshot-time and current ignore rules, including.gitignoreand.git/info/exclude. The change records only ignored paths that exist at save time inzoo-checkpoint-ignored/<hash>.restoreCheckpointchecks those recorded paths and current rules, but it does not save or evaluate the snapshot ignore configuration. A file created after the checkpoint can match a snapshot-time rule, become unignored by the current rules, and still be removed. The reported existing-file scenarios are covered by tests. The separatewrite_to_fileproposal is not required for this focused rollback change.Resolution
Persist the snapshot ignore configuration, including
.gitignoreand.git/info/exclude, or otherwise evaluate the snapshot-time rules against every untracked path during restore. Add a regression test for a file created after the checkpoint that matches only the snapshot-time rules.
Full details: Persistence Integrity
-
Explanation
The changed ignored-path record uses an unsynchronized read-modify-write.
recordIgnoredPathsreads the existing record and current ignored paths, then writes a temporary file and atomically renames it atShadowCheckpointService.ts:308-319. The rename is atomic per writer, but concurrentsaveCheckpointcalls can overlap because the caller starts one withvoid this.checkpointSave(...)(src/core/task/Task.ts:2415). If save A reads the old record, save B records a newly ignored path and publishes it, and save A then publishes its stale merge, B's path is lost. A later restore can delete that path after the ignore rules change.Resolution
Serialize ignored-record read/list/merge/publish operations for each checkpoint record, or use an equivalent per-record lock/compare-and-retry mechanism. Keep the existing temporary-file-plus-rename publication inside that critical section. Add a concurrency regression test that performs overlapping no-change saves while the ignored-path set changes, then verifies the final record contains the union and restore preserves both paths.
Full details: Regression Evidence
-
Explanation
Focused coverage remains incomplete. The changed save path merges existing metadata with paths found during a no-change save (
ShadowCheckpointService.ts:312-315, 462-467), but the tests only exercise that path under forced write/rename failures (ShadowCheckpointService.spec.ts:551-584). No test successfully saves the same commit twice with different ignored paths and verifies that both paths survive restore. The restore implementation also combines checkpoint-time and current ignored paths (ShadowCheckpointService.ts:329-333), but coverage uses a current-only ignored directory (ShadowCheckpointService.spec.ts:587-609), not a current-only ignored file alongside removal of an unrelated untracked file.Resolution
Add focused integration tests in
ShadowCheckpointService.spec.ts. First, save a checkpoint with ignored path A, change the ignore rules to ignore path B, perform a successful no-change save that reuses the same hash, and restore while asserting that both paths remain. Second, create a file ignored only by the current rules and an unrelated untracked file, remove the current rule, restore, and assert that the ignored file remains while the unrelated file is removed.
Full details: Lifecycle Resource Cleanup
-
Explanation
The changed initialization path can leak checkpoint listeners.
initShadowGitnow callsrecordIgnoredPathsafter the initial commit (ShadowCheckpointService.ts:222-224), butrecordIgnoredPathspropagates read, listing, mkdir, write, or rename errors (lines 307-322).checkGitInstallationregistersinitializeandcheckpointlisteners first (index.ts:160-194), catches the initialization failure without removing them (198-203), andgetCheckpointServicestill assigns the failed service totask.checkpointService(index.ts:113-120). A metadata write or permission failure can therefore retain listeners that capture the task and provider.Task.disposeremoves Task listeners, not listeners on the checkpoint service, and the service has no disposal path.Resolution
On initialization failure, remove the listeners registered by
checkGitInstallation, cleartask.checkpointService, and settask.checkpointServiceInitializingtofalse. Also dispose or otherwise release the failed checkpoint service. Alternatively, make ignored-path metadata publication non-throwing while preserving an explicit failure state when required metadata is unavailable.

Review comments at
@src/services/checkpoints/__tests__/ShadowCheckpointService.spec.ts:
- Around line 350-352: Update the ignore-rule tests around saveCheckpoint in
ShadowCheckpointService.spec.ts, including the test starting at line 324, to use
an untracked secret path and assert before saving that the shadow Git index does
not track it and git check-ignore reports it as ignored. Include a positive
control confirming the ignore rule matches, using behavior-focused assertions.
- Around line 369-383: Update the legacy-checkpoint test around `saveCheckpoint`
and `restoreCheckpoint` to distinguish the fallback cleanup path: create a path
ignored when the checkpoint is saved, change its ignore rule, remove the ignore
record, then assert that restoration produces the expected legacy `git.clean`
result for that path.
Review comments at @src/services/checkpoints/ShadowCheckpointService.ts:
- Around line 316-318: Update the `git.raw` `ls-files` invocation in the restore
flow to include directory entries with `--directory`, so empty untracked
directories are considered for cleanup. Preserve the existing safeguards that
prevent deleting directories containing preserved files.
- Line 297: Update the ignored-record write in ShadowCheckpointService to write
the serialized paths to a temporary file and rename it to the path returned by
ignoredRecordPath only after the write succeeds, preserving the existing record
if writing fails.

recordIgnoredPathsis deliberately fail-closed.saveCheckpointupdates_checkpointsonly after the record succeeds, and restore rejects marked commits without valid metadata. Making record failures non-fatal would allow unusable checkpoints to be reported as successful.The tests explicitly require metadata write or rename failures, and subsequent no-op saves after a missing record, to reject. The caller disables checkpoints after such failures to prevent unsafe restores.

Assert that the injected fs.rm failure was exercised.
The suite-level afterEach restores all mocks even when the test rejects, so try/finally is not needed for cross-test cleanup. The test should still assert that restoreCheckpoint attempted to remove stuck-untracked.txt.

357 - 369:
Update the test around restoreCheckpoint to assert that the mocked fs.rm was
called with untracked and the expected force, recursive options, confirming
removal of stuck-untracked.txt was attempted. Keep the existing checkpoint
restoration and tracked-file reset assertions unchanged.
After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
restoreCheckpoint ran `git clean -f -d -f` against the workspace's current ignore rules. Files ignored when a checkpoint was saved were never committed to it, so after .gitignore changed (for example, an agent overwrote it) they were no longer ignored and the clean deleted them. Each checkpoint now records the paths ignored when it was saved (`git ls-files --others --ignored --exclude-standard --directory`). Restore removes only untracked files ignored by neither the current rules nor that record, then prunes directories left empty, as `git clean -d` did. Checkpoints saved before this change have no record and keep the previous clean. Fixes Zoo-Code-Org#1832 Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Description
restoreCheckpointrangit clean -f -d -fbeforegit reset --hard, and the shadow repo's worktree is the workspace, so the clean applied the workspace's current ignore rules. Files that were ignored when the checkpoint was saved were never committed to it. If.gitignorechanged afterwards (in the issue, an agent overwrote it withwrite_to_file), those files were no longer ignored and the clean deleted them. This also happens when.gitignoreitself is in the checkpoint, because the clean runs before the reset restores it.This PR follows the issue's second suggestion: a file is kept if it is ignored under either the checkpoint-time rules or the current rules.
initShadowGitandsaveCheckpoint), the paths ignored at that moment are recorded withgit ls-files --others --ignored --exclude-standard --directory. Fully ignored directories such asnode_modules/collapse to one entry. The record is stored per commit at<shadow .git>/zoo-checkpoint-ignored/<hash>. Repeated saves of the same hash add to the record rather than replace it. A recording failure is logged and never fails the save.git ls-files --others --exclude-standard(current rules), and any path covered by the checkpoint's record is skipped. The rest are removed, and directories left empty are pruned, asgit clean -ddid. Nested repositories listed asdir/are removed recursively, as the previous-f -fdid.git clean -f -d -fbehaviour.Not included: the issue's first point, making
write_to_filerefuse to overwrite existing files. That changes the tool's intended behaviour rather than fixing a defect, so it's left for maintainers to decide separately.Test Procedure
New tests in
ShadowCheckpointService.spec.ts(real git repositories in temp directories):.gitignorelists itself andsecrets/, a checkpoint is saved, then.gitignoreis overwritten. After restore,secrets/key.txtis kept, the never-checkpointed.gitignoreis kept as-is, and a file created after the checkpoint is removed..gitignorethat changes:secrets/key.txtis kept,.gitignoreis restored, and a file created after the checkpoint is removed together with its new directory.The first two tests fail on
main(ENOENTforsecrets/key.txt, i.e. the file was deleted).cd src npx vitest run services/checkpoints core/checkpointsResults: all checkpoint suites passed; type checking and ESLint passed (also via the commit hook). ESLint suppression counts are unchanged.
