Show Codex turn latency and throughput per conversation - #899
Conversation
Make the bounded JSONL reader and request-usage helpers crate-visible so the Codex workspace turn scanner can reuse them. No behavior change.
Scan completed Codex turns from local rollout logs and summarize first-token latency, turn duration, and output throughput per session. A turn counts only with a successful task_complete, owned usage records that sum to the reported total, and no contradictory copies. Scans reuse the bounded JSONL reader and the indexer merges results by turn id. The sidecar payload version is bumped so stale snapshots rebuild.
Add the Usage & Spend performance labels, help text, and caveats to every locale and the TypeScript key list in parity.
Render turn output rate, first-token and turn duration under each Codex conversation in Usage & Spend, with a Performance details disclosure for P95 latency, the middle-50% rate range, cached input share, and per-model and effort groups. Values appear only once the minimum sample counts are met.

Explanation
The changed path is Codex-specific:
CodexWorkspacesIndexscans rollout files and stores only turn metrics, model, and reasoning-effort groups inSessionUsage.turnPerformance. The sidecar persists this Codex snapshot, andProjectConversationsrenders the same Codex conversation data. The diff adds no identity, plan, account label, or email fields, logs, or exports. It also adds noProviderId-specific branch. Existingload_native_spendgating returns empty native conversations for non-Codex providers and is unchanged by this pull request.
Full details: Secrets Handled Safely
-
Explanation
No credential exposure or cross-application credential mutation was introduced. The new scanner opens rollout files read-only and stores only numeric metrics plus normalized model/reasoning-effort labels; it does not log raw payloads or include credential fields in snapshots. The diff adds no tracing, println, console, or user-error output carrying input data. Sidecar writes remain confined to CodexBar's own
local-usage/codex-workspaces-v1.sqlite; no keyring, credential-file, or Codex login changes were added. Test file writes target temporary rollout fixtures.
Full details: No Unapproved Dependencies
-
Explanation
The reviewed diff changes no Cargo.toml or package.json file. It adds no npm, Yarn, or pnpm lockfile, and it does not change a pinned pnpm packageManager version. The custom check therefore has no failure condition.
Full details: Ui Changes Include Windows Proof
-
Explanation
The pull request changes visible Settings UI in
ProjectConversations.tsxby adding per-conversation performance metrics and expandable details. The description includes Windows proof: a freshpnpm run tauri:build:debug, a Windows executable path, CDP assertions, and named screenshots. The check requirement is satisfied.

Name the output-rate range in both translations. Both strings describe the middle 50% of turns without identifying the throughput statistic.

Summary
Ports upstream Codex turn latency and throughput metrics (steipete#4304, v0.75.0).
codex_workspaces/turn_performance.rs) reads Codex rollout logs and keeps only turns with a successfultask_complete, a positive duration, and ownedtoken_usage_recordrequests that sum to the reported output. Contradictory usage, failed turns, first-token time greater than duration, other threads' usage, and turns outside the date range are dropped. Oversized relevant lines drop the file.SessionUsage.turn_performance(serde defaultNone); sidecar payload version 3 → 4 so cached snapshots rebuild.Differences from upstream:
