when a provider transcript disappears, the usage page drops its saved tokens, costs, and sessions, then erases its cache entry. retain saved usage within the existing 90-day window and persist source identities so deleting a symlinked directory does not hide history or double-count pre/post-cleanup environment summaries. match moved codex rollouts while preserving repeated equal events within one rollout.

verification: 72 scoped usage and client-merge tests, server typecheck, and scoped lint passed on blacksmith. the deletion regression fails on the original code. a copied real codex transcript retained 76,767 tokens, $0.1015192, and one session through the websocket endpoint and client merge after deletion, directory removal, restart, and a move; alias-only root deletion, recreation with a different inode, restart, and merging pre/post-cleanup snapshots also preserved totals and source identity. browser rendering is unverified because preview automation is unavailable.

this fix cannot reconstruct pruned records whose transcripts are gone, or directory identities never saved by older versions. source identity is learned by scanning an existing root. separate follow-up: the existing newest-environment ownership policy can hide older saved history when environments have different caches for the same source.

model: gpt-6; harness: codex.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR changes production usage accounting and durable cache identity so token totals, costs, and sessions persist across transcript cleanup and restarts. The added cross-file deduplication and source-recovery logic has a broader behavioral and metering impact than a routine bug fix.

📝 Walkthrough

Walkthrough

Usage scanning now persists transcript source identities, preserves repeated equal Codex events, retains cached records during source recreation, and prunes scan-cache entries by retention cutoff. Tests cover cleanup, symlinked directories, recreated sources, merged environments, and Codex totals.

Changes

Usage cache identity and deduplication

Layer / File(s) Summary
Retention-only cache pruning
apps/server/src/usage/usageScanCache.ts, apps/server/src/usage/usageScanCache.test.ts
pruneScanCache now removes entries only when they are older than the retention cutoff. The PruneOptions interface and window/path checks were removed.
Stable transcript source identities
apps/server/src/usage/UsageService.ts
UsageService caches directory and volume identities, restores them from the scan cache, falls back to cached values when resolution fails, preserves retained cached records, and reuses the cached volume identity during collection.
Codex event occurrence validation
apps/server/src/usage/UsageService.ts, apps/server/src/usage/UsageService.test.ts
Tests preserve repeated equal Codex events and validate cleanup, recreated sources, merged summaries, and updated totals.

In `@apps/server/src/usage/UsageService.ts`:
- Around line 513-520: Update the transcript cache retention logic around
listTranscriptFiles and resolveTranscriptDirs to preserve the configured source
identity when a symlink target is unavailable. Store or reuse a stable
source-root identity in each cache entry, and use it for the containment check
instead of comparing resolved cache paths lexically against the fallback symlink
path; retain the existing age and live-path filtering behavior.
- Around line 546-552: Update the dedupeKey construction in UsageService so
Codex event identity does not rely on equality of provider, sessionId,
timestampMs, model, and totals; use a stable Codex event discriminator when
available, otherwise restrict deduplication to confirmed moved-rollout copies.
Add a regression test covering an A–B–A last_token_usage sequence and ensure
both A records are preserved.

Merges `pingdotgg/t3code` `6d1d549441..9946541` (50 commits) into the
fork.

Landed 304 files against 303 in the upstream range — the extra one is
`docs/fork/inventory.json`. Fork delta is 777 files, unchanged from the
last
merge. Everything upstream changed landed.

Six conflicts, each resolved with the verdict `preflight.mjs` printed;
five were
a single hunk. Details and reasoning are in
[the merge tracker](docs/fork/upstream-merge-log.md). The two worth
reading here:

- **`ChatView.tsx`** — pingdotgg#12306 added `activeWorktreePath !== null` to the
"Revert
  files too" button, on the line the fork gates with
`FEATURES.checkpointFileRestore`. Kept both as a conjunction: upstream's
condition is about a shared workspace, the fork's is about what Moatless
  serves, and they answer different questions.
- **`FilePreviewPanel.tsx`** (the one `decide`) — pingdotgg#10909 restructured
the file
read so a folder is knowable as a folder, adding `isDirectory` /
`previewPath`.
Took that whole and re-stated the fork's `onRetargetFile` effect on top.

`apps/web/src/routeTree.gen.ts` was regenerated rather than
hand-resolved.

One judgement call: pingdotgg#11598's new `/settings/storage` page is
deliberately **not**
given a `FEATURES` gate. It self-gates on two new capability booleans
Moatless
does not report and renders an explanatory notice, so a fork flag would
duplicate
a decision the wire already makes — and would have to be deleted again
the day
the capability is reported.

## Usable as-is

- Diff files open from a right-click context menu (pingdotgg#11842).
- Sidebar filtering from the thread menu (pingdotgg#8719).
- Command palette matches thread IDs (pingdotgg#11185).
- Mobile settings are easier to navigate and scope (pingdotgg#12272); favorites
in the
  mobile model picker (pingdotgg#12231).
- Thoughts collapse within tool groups (pingdotgg#12302); thoughts and failed
tool calls
  stay in one activity row (pingdotgg#12270).
- Folder links from chat open the file tree instead of a broken preview
(pingdotgg#10909).
- Chat no longer jumps when the scroll-to-end pill mounts (pingdotgg#12317);
numbered
jumps no longer steal browser tabs (pingdotgg#12315); composer banners stay
compact
  (pingdotgg#12166).
- A large batch of shared-component refactors across web and mobile
(pingdotgg#12353pingdotgg#12371).

## Unsupported in Moatless / needs implementation

- **Pull request files marked as viewed** (pingdotgg#7721) — adds
`pullRequests.filesViewed` and `pullRequests.setFilesViewed`, which
record
which files a reviewer has checked off, persisted server-side. Both
declare
  `PullRequestRpcError` and so arrived already refusing;
`unsupported-methods.mjs` reported ADD 0 / DROP 0 as a result. Closes
with the
  rest of the `pullRequests.*` group, not separately.
- **Multi-model threads in separate worktrees** (pingdotgg#12179) — one prompt
starts a
thread per selected model, each in its own worktree. The model picker is
the
same `worktree` send-mode control `FEATURES.worktreeSelection` already
gates,
  so the fan-out is simply not offered. The same commit adds a
  `requiredWorktreeBootstrap` capability the backend does not report.
- **Automatic storage cleanup settings** (pingdotgg#11598) — the
`/settings/storage` page,
gated by the backend's absent `storageCleanup` and
`projectWorktreeCleanup`
  capabilities. Needs the sweeper below before the page means anything.
- **Command palette entries for the pull requests and usage pages**
(pingdotgg#12211) —
  the PR half is covered by `FEATURES.pullRequestSurface`.

## Backend behavior to consider reproducing in Moatless

Eight items, recorded in full in [the gaps register](docs/fork/gaps.md)
under
_Runtime fixes upstream made to its own server_. Five are on the
checkpoint and
usage paths the previous merge already opened:

- **Reject a file rewind on a shared or nested-owner cwd** (pingdotgg#12306,
`CheckpointReactor.ts`) — a checkpoint holds the whole checkout, so
restoring
one erases a sibling's uncommitted work. Moatless isolates by sandbox,
but a
workspace with nested repositories has the same overlap inside one task.
- **Capture a checkpoint when the baseline lookup fails** (pingdotgg#12307) — the
case
  that silently leaves a turn with no restore point.
- **Move the file-search refresh off the checkpoint path** (pingdotgg#12308) — it
  extended every capture by an index walk.
- **Survive an empty nested repository, and clear a stale index lock**
(pingdotgg#12181,
`GitVcsDriver.ts`) — git cannot stage an embedded repository until it
has a
commit. The lock half matters most here: forced termination is the
normal end
  of a sandboxed task.
- **Bound the provider event log before serialization** (pingdotgg#12305,
`EventNdjsonLogger.ts`) — otherwise it grows proportionally to tokens
streamed.
- **Keep usage totals across transcript cleanup** (pingdotgg#12304,
`UsageService.ts`) and
  **resolve a contested fingerprint to the newest scan** (pingdotgg#10315,
  `usageMerge.ts`). Moatless serves `server.getUsageSummary` itself.
- **Pass provider image attachments by path** (pingdotgg#11050,
`CodexAdapter.ts`) — the
turn/start request stops scaling with attachment size. A sandbox adds a
hop, so
  an oversized request costs more there.
- **Sweep stale worktrees and transcripts against retention rules**
(pingdotgg#11598,
`storageCleanup.ts`, with a workspace lease so two servers cannot sweep
the
same directory). A sandbox per task bounds the worktree half;
transcripts
  outlive the sandbox.

## Verification

`verify.mjs` — all 9 checks green on the first full pass, tests included
(333 test files, 5071 tests). No flaky retries and no caveats.

Contract drift: ADD 0 / DROP 0, so `packages/contracts/src/rpc.ts`
needed no
change. The `orchestration-decode-boilerplate` duplicate-add exception
went stale
— the colliding line is gone — and was deleted from `inventory.json` in
this
merge.

Owned-concern sweep: the three new
`apps/mobile/src/features/connection/` files
are false positives, all upstream extracting shared mobile components
out of
files it already owned, with no fork delta in any of them.
