Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds read-only Codex log diagnostics, but current error handling may expose private filesystem paths and altered database schemas may be reported as compatible, which could lead to unsafe protection or reclaim decisions later. Merge should wait until diagnostic failures are sanitized and schema objects are fully validated; localized status guidance also remains a follow-up. Possibly related PRs

Triage note (2026-08-15): substance is close (CI green at head except gates below), but staying draft on three items: (1) the unresolved security/privacy thread — the inspection report serializes sqliteHome/databasePath/codexHome through the API/CLI/UI; keep the serializable surface to safe metadata and return fixed error codes (e.g. inspect_failed) instead of raw error.message at both boundaries; (2) the hygiene gate fails on the deliberate empty_catch blocks; (3) the GUI screenshot is still pending for enforce-target. The i18n nit on the new Storage panel strings also needs locale keys. |

- Around line 117-135: Update the shared formatBytes formatter in
format-bytes.ts to retain the existing 1024-based scaling while emitting the
locale-invariant binary symbols B, KiB, MiB, GiB, and TiB. Then update the
corresponding Log Guard rendering expectations in storage-log-guard.test.tsx to
match the new symbols.
- Line 69: Update the StorageWorkspace rendering branch around codexLogs and
codexLogsError to show a localized unavailable panel when codexLogs is null and
the error matches a recognized fixed code; do not display arbitrary error
strings, and preserve the existing rendering for available logs. Add the
required user-facing text to the i18n locale files and create a rendering test
covering this inspection-failure branch.
In `@src/cli/codex-log-guard-doctor.ts`:
- Around line 14-25: The formatter should report file metadata for every schema
state, including unreadable databases, and include the SHM size alongside DB and
WAL sizes. Update the logic around the unreadable early return in the doctor
formatter to preserve the status line but continue emitting location, database,
WAL, and SHM sizes before optional metrics. Add formatter tests covering
unreadable reports and SHM output.
In `@src/codex/log-guard/inspect.ts`:
- Around line 113-118: Update sameColumns and the schema-validation flow to
require logs to be a table, not a view, and compare the pinned PRAGMA
table_info(logs) attributes—including types and constraints—rather than only
column names. Ensure protection and reclaim are marked supported only after this
full compatibility check, and add regression tests covering a same-name view and
a changed column definition.

other stat failures become database_unreadable at the canonical-target handling

a regression test for a path- or token-like logs.target and assert the

and topTargets query: map levels to a fixed known enum with all unrecognized
values grouped as OTHER, and remove target names in favor of non-identifying
aggregate counts. Update the report contract and all API, CLI, GUI, and
regression-test consumers so no raw database values are serialized or exposed.

- Around line 244-247: Update the inspection flow around resolveCodexSqliteHome
and resolveCodexLogsDbPath to resolve sqlite_home once, derive the canonical
database path from that resolved value, and catch resolution failures before the
existing try boundary. Return a fixed inspect_failed/unavailable result without
serializing the caught error or path, and adjust the result contract so unknown
location metadata is represented as unknown rather than a false concrete value.

logs-owned indexes and triggers in addition to the table columns and schema SQL.
Compare normalized sqlite_schema DDL for each expected named object, returning
compatibility only when all required objects match; add regression coverage for
a missing known index and an unexpected trigger.

Approving after an independent adversarial audit (gpt-5.6-sol explorer) plus a re-audit of the fixes.
Round 1 returned FAIL on three blockers. All are now closed:
- Storage inspection blocked the proxy thread. readMetrics runs four unbounded aggregates and bun:sqlite is synchronous; measured 48.8s on a real 15.6 GB / 302k-row database, on a path both /api/storage and /api/storage/codex-logs call inline. Inspection is now memoized on file identity, so repeat scans are free (60k-row fixture: 14.3ms cold, 0.1ms warm). The remaining cold-scan cost is explicitly disclosed in the source comment and left for a Worker-based follow-up rather than claimed as fixed.
- Cache identity was unsound. Re-audit showed size+mtime lets an atomic replace go unnoticed, serving a stale schema verdict indefinitely. Key now includes dev+ino and nanosecond mtime/ctime; regression drives the exact replace-at-identical-size case.
- Missing focused regressions. Added for memoization, write invalidation, explicit reset, and atomic replacement.
Verified at 3307261 on an isolated Linux checkout: tests/codex-log-guard-inspect.test.ts 17 pass / 0 fail, bun x tsc --noEmit exit 0, all GitHub checks green.
Approving as the stack parent so #1729 and #1732 can follow.

Upstream registers these filters with First fix used The #1729 — a concurrent Repair could undo a completed Disable (High). Repair read the desired mode before acquiring the cross-process lock, so a Disable landing in that gap completed successfully and was then silently reinstalled. The caller saw "off" and got "compat".

… proxy
readMetrics runs four unbounded aggregates over the whole logs table -
count(*), two GROUP BYs, and a sum. bun:sqlite is synchronous, so that work
occupies the proxy thread for its full duration. Measured on a real 15.6 GB /
302k-row database:
{"elapsedMs":48848.1,"totalRows":302726,"databaseBytes":15602388992}
Both /api/storage and /api/storage/codex-logs call inspectCodexLogs inline, so
opening or refreshing the Storage page could stall routing and health responses
for tens of seconds - on exactly the large fragmented database this feature
exists to diagnose.
Inspection is now memoized on the identity of the database, WAL, and shm files
(size + mtime). A dashboard refresh, a page rendering both panels, and a poll
loop all repeat an identical scan; those repeats are now free. Any Codex write
changes the WAL stamp and invalidates the entry, so a cached answer is never
staler than "nothing has been written since", and generatedAt is part of the
memoized value so it reports when the numbers were measured rather than served.
Measured on a 60k-row fixture: cold 14.3ms, warm 0.1ms, and 13.9ms again after
resetCodexLogGuardInspectionCache().
Scope, stated honestly: this bounds the REPEAT cost, not the first one. A cold
inspection of a very large database still blocks the thread. Moving that work
onto a Worker is the real fix and is left for its own change; this removes the
repeated stalls that make the page unusable in practice.
Regressions cover memoization, write invalidation, and the explicit reset.
…time
Re-review showed size:mtimeMs is not an identity: an atomic replace (write a
new file, rename over the old) can preserve both, and the cache then served the
previous schema/capability verdict indefinitely. That trades a repeated-scan
cost for a persistent wrong answer, which is the worse failure.
The key now includes dev+ino (a replaced file is a different inode) and
nanosecond mtime/ctime (an in-place rewrite inside one millisecond still
invalidates), via statSync(path, { bigint: true }).
Regression drives the exact case: replace the database with a same-size
non-database file, restore the original mtime, and assert the next inspection
is neither the cached object nor still 'compatible'.
