Inline comments:
In @.github/workflows/log-guard-reclaim-tdd.yml:
- Around line 3-4: Add workflow-level concurrency to the pull-request workflow,
using a group key that uniquely identifies the pull request and enabling
cancel-in-progress so superseded runs are cancelled. Keep the existing trigger
and job configuration unchanged.
In `@src/codex/log-guard/maintenance.ts`:
- Around line 270-274: Update the comment above the final checkpoint to describe
only the guarantees of checkpointFull, and document walBytes in
CodexLogGuardCompactionMeasure as an on-disk WAL size that may remain unchanged
after a FULL checkpoint, not a reclaimable WAL metric. Keep the FULL variant and
existing measurement flow; do not truncate or rename Codex WAL files.
- Around line 100-109: Update runCompaction to re-validate databasePath
immediately after opening it, mirroring withCodexLogGuardLock: lstat the path,
verify it remains a regular non-symlink file, compare realpath identity with
samePathIdentity, and validate the opened handle’s identity (preferably using
the pre-open and post-open st_dev/st_ino values) before running any SQLite
writes; abort and close the handle on failure.
- Around line 232-264: Classify exhaustion of MAX_ITERATIONS after successful
reclamation as page_budget rather than no_progress, including runs that reach
the cap on the first iteration; update stopReason initialization and the
post-loop handling around the incremental vacuum loop accordingly. Preserve
no_progress only for iterations where currentFreelist fails to decrease, and add
a regression test covering continuous progress until the iteration cap and
asserting the exported report’s stopReason.
In `@tests/codex-log-guard-maintenance.test.ts`:
- Around line 172-186: Extend the “fails closed” test for compactCodexLogs so
processCheck returns an ok, empty result on its first invocation and a running
Codex process on its second invocation, then assert the result is { ok: false,
error: "codex_running" }. Use call-count state in the existing test dependency
setup to verify the post-lock process check remains enforced.
- Around line 188-196: Add a focused regression test near the existing
compactCodexLogs tests that opens a reader transaction against a WAL fixture,
invokes compactCodexLogs while the reader remains active, and asserts the
documented busy/checkpoint refusal. Also capture and verify that the freelist
count is unchanged, distinguishing SQLite checkpoint contention from the
existing Log Guard lock test.

Triage note (2026-08-15): staying draft — the dedicated reclaim workflow's GUI contract step fails at head and the gates job is red, and two Major review threads look plausible (post-open path re-validation gap in runCompaction, and the iteration-cap stopReason misclassification). Also consider dropping the one-off log-guard-reclaim-tdd.yml workflow, which duplicates main CI coverage. |

Inline comments:
In `@docs-site/src/content/docs/guides/codex-log-guard-reclaim.md`:
- Line 98: Update the partial-result explanation near the freelist completion
semantics to include the finite iteration-cap outcome and state the API’s exact
stopReason for that condition, distinguishing it from page-budget exhaustion and
SQLite no-progress termination. Keep the existing retry behavior description
unchanged.
In `@gui/tests/storage-log-guard-compact.test.tsx`:
- Around line 47-48: Remove sqliteHome and databasePath from the
CodexLogGuardReport fixture, and replace the unsafe StorageReport cast near the
fixture with satisfies StorageReport so the GUI fixture enforces the
path-private response contract.
In `@src/codex/log-guard/maintenance.ts`:
- Around line 251-275: Update runCompaction’s mid-loop checkpointFull busy
handling so reclamation already completed is reported to the caller instead of
returning a pure busy error. When at least one incremental-vacuum batch has
landed, preserve pagesReclaimed, before, and after and return a successful
result with stopReason “busy”; keep the pre-loop busy failure behavior
unchanged.
In `@tests/codex-log-guard-maintenance-coderabbit.test.ts`:
- Around line 140-159: Wrap the reader transaction, compaction, and freelist
assertions in a try/finally so the reader handle is always rolled back and
closed, including when an operation throws. Update the test around
compactCodexLogs and scalar while preserving the existing expectations;
optionally apply equivalent finally-based cleanup to the writer handle.
- Around line 74-84: Update the deps helper’s extra parameter to use the
exported CodexLogGuardMaintenanceDeps type via a type-only import, so injected
dependency keys are checked against the actual dependency contract and
misspellings cannot be silently ignored.

- Around line 403-411: Update the compact branch in the action handler so a
successful compaction POST remains successful when the follow-up codex-logs GET
or JSON parsing fails: treat refresh as best effort, preserving the existing
report or setting a separate localized refresh warning instead of logGuardError.
Add a regression test covering successful POST followed by failed GET.
Apply the same fix in `@gui/tests/storage-log-guard-compact.test.tsx` around lines
93 - 108: The existing test bypasses the built-in request path, so it does not
cover the affected POST and refresh behavior.
In `@src/codex/log-guard/maintenance.ts`:
- Around line 315-320: Update the compaction catch path around runCompaction and
its finish reporter so a thrown SQLITE_BUSY after committed work preserves
partial-success results, including pagesReclaimed, iterations, before, and
pageSize; hoist the loop state outside try, report busy only as partial success
when iterations > 0, and retain the existing refusal for busy before any batch
completes. Add a regression test beside the existing partial-success test that
forces incremental_vacuum to throw busy after one committed batch.
In `@tests/codex-log-guard-maintenance-coderabbit.test.ts`:
- Around line 131-144: Update the test for continuous progress stopped by
MAX_ITERATIONS to assert the precondition that
result.report.before.freelistPages exceeds MAX_ITERATIONS before checking the
stop reason and iteration count, so fixture drift is reported as a fixture
failure. Keep the existing assertions for bounded work unchanged.
- Around line 173-212: Document in the test that the blocking-reader setup
depends on runCompaction reading deps.batchPages after the initial checkpoint,
and track the getter invocation count. Assert it fires exactly once while
preserving the existing partial-success expectations; update the maintenance
dependency seam only if needed to make this ordering contract explicit.

Pre-merge review — four findings, all still openAudited independently at Four findings remain. I have not fixed these — unlike the #1727/#1729 findings, each needs a product decision about what the documented contract should be, and guessing would just move the inconsistency somewhere else. 1. Medium — the implementation does not honor the documented byte budgets.
Either derive page counts from 2. Medium — the documented
3. Medium — two new maintenance errors fall through to a generic dashboard message.
4. Medium — the dashboard discards successful compaction results.
So Also blockingThis is the top of a stack, so #1727 and #1729 must land first. Both are fixed and restacked but blocked on approval from someone other than For context, this batch already landed on |

… surface both new errors and the compaction result Four findings from independent review, all confirmed against the code. 1. Byte budgets were not honored. DEFAULT_BATCH_PAGES/DEFAULT_MAX_PAGES_PER_RUN were fixed page counts while the guide promises ~8 MiB batches and ~256 MiB per run converted with the real page size. At the 4 KiB pages the fixtures use that was 2 MiB/32 MiB - a quarter of the documented budget. Budgets are now expressed in bytes and converted after reading PRAGMA page_size; explicit page-count overrides still win. 2. logicalBytesReclaimed was documented but never existed in the report contract. Now emitted as pagesReclaimed * pageSize, and deliberately distinct from physicalDatabaseBytesReclaimed: an incremental vacuum can reclaim pages without the file shrinking, so logical progress with zero physical shrinkage is normal rather than a failure. 3. auto_vacuum_not_incremental and integrity_check_failed fell through to the generic dashboard message, so a user could not tell an unsupported configuration from a suspect database. Both now have labels in 9 locales and explicit cases in mutationErrorLabel. 4. The dashboard discarded successful compaction results. It checked that the POST succeeded but never read its report, then attempted a best-effort refresh; if that refresh failed the user saw no outcome at all, hiding pagesReclaimed/complete/stopReason and inviting a repeat of a mutation that already worked. The POST report is now parsed and retained independently of the refresh, and rendered in the reclaim section.
…d include pages/stopReason
Re-review found the fourth fix incomplete in two ways, both reproduced.
1. A fully successful compaction drives reclaimableBytes to 0, which retires the
reclaim section - and the result was nested inside it, so the outcome
vanished in exactly the best case:
REFRESHED_RECLAIMABLE=0
RESULT_PRESENT_AFTER_SUCCESSFUL_REFRESH=false
The result now renders in its own section, independent of reclaimAvailable.
2. The summary omitted pagesReclaimed and stopReason, so a user could not tell
page_budget from no_progress from busy:
SHOWS_PAGES=false
SHOWS_STOP_REASON=false
Both are now included. The page unit is a localized label rather than a
hardcoded string, which the i18n lint correctly required.
Regressions: a successful compaction whose refresh fails still shows its report
with the page count and stop reason, and a completed compaction whose refresh
retires the reclaim section still shows its result.
…form in zh-TW Two findings from the final review round. A failed retry left the previous success receipt on screen next to the new error, so the section misreported the latest attempt. The receipt is now cleared when a compaction starts. zh-TW carried the Simplified page unit; it now uses the Traditional form.

Approving after independent audit and three rounds of fixes; the final round returned PASS with zero blockers.
Findings closed:
- Byte budgets were fixed page counts while the guide promised ~8 MiB batches and ~256 MiB per run converted with the real page size (at 4 KiB pages that was 2 MiB/32 MiB). Budgets are now byte-based and converted after reading PRAGMA page_size.
- logicalBytesReclaimed was documented but never existed; now emitted as pagesReclaimed * pageSize, deliberately distinct from the physical figure since an incremental vacuum can reclaim pages without the file shrinking.
- auto_vacuum_not_incremental and integrity_check_failed fell through to the generic message; both now have labels in all 9 locales and explicit routing.
- The dashboard discarded successful compaction results. Follow-up review then found the first fix incomplete twice over: the result was nested inside the reclaim section, which a fully successful compaction retires, and the summary omitted pagesReclaimed/stopReason. Both fixed, plus a stale receipt no longer survives a failed retry, and zh-TW uses the Traditional page unit.
Verified remotely at the audited head: typecheck exit 0, Log Guard 85 pass / 2 skip / 0 fail, GUI 881 pass / 0 fail, gui lint and lint:i18n clean. Every new regression was reproved to fail without its source change.
