Session detail loading and validation rust/src/codex_workspaces/*, rust/src/core/jsonl_scanner/* |
The Rust loader reads matching rollout files within request and size limits, groups request usage by turn, and checks the results against a summary checkpoint. The Codex scanner supports an optional record limit. Tests cover grouping, limits, unavailable sessions, and changed sources. |
Session detail command and bridge apps/desktop-tauri/src-tauri/src/commands/codex_workspaces.rs, apps/desktop-tauri/src-tauri/src/main.rs, apps/desktop-tauri/src/types/bridge/settings.ts, apps/desktop-tauri/src/lib/tauri.ts, apps/desktop-tauri/src/proof/* |
The Tauri command accepts a session ID, checkpoint, and optional history window. The bridge and proof routes expose the command and provide synthetic detail fixtures. |
Sessions search, sorting, and details apps/desktop-tauri/src/lib/sessionInspector*, apps/desktop-tauri/src/surfaces/settings/tabs/*, apps/desktop-tauri/src/i18n/keyGroups/providerText.ts, apps/desktop-tauri/scripts/proof-scenarios.json, rust/src/locale/*, docs/CONFIGURATION.md |
The Sessions view filters and sorts conversation summaries, then requests and displays selected-session details. Tests and proof scenarios cover selection, detail errors, stale responses, and tool activity. Documentation and locale strings describe the view. |

Explanation
PASS. The PR adds Codex-only session inspection.
UsageSpendTabpassescodex_period_contract.conversations, which is populated fromCodexWorkspacesIndexdata. The new Tauri command and Rust loader read only Codex rollout files. The added bridge payloads contain session usage and request details, not provider identity, account labels, plans, or email. No new cross-providerProviderIdbranching appears in shared code.
Full details: Secrets Handled Safely
-
Explanation
The changed code does not send credential material to logs, user errors, snapshots, or plain-text files. The new detail path returns usage counts, pricing, model names, timestamps, and session IDs; its errors are fixed codes (
unavailable,sourceChanged, andlimitExceeded). The only added file writes are synthetic test fixtures. No changed code deletes or overwrites credential files or keyring entries.
Full details: No Unapproved Dependencies
-
Explanation
The pull-request diff changes no Cargo.toml or package.json file, adds no npm, Yarn, or pnpm lockfile, and does not change a packageManager pin. The existing apps/desktop-tauri/pnpm-lock.yaml is unchanged. Maintainer approval is therefore not required.

-
Explanation
The PR changes visible Settings UI in
SessionInspector.tsxand replaces the Sessions view inUsageSpendTab.tsx. The PR description includes proof checks reporting 3 screenshots for the new session-inspector scenario and 3 screenshots for tool activity. The changed proof scenario defines list, detail, and unavailable screenshots.

@coderabbitai Fixed. The loader now passes its remaining request budget to the parser and stops early instead of buffering the whole file.
Checks: fmt clean; clippy clean on both manifests; |

Summary
Ports upstream CodexBar steipete#4730 (commit bf00709, "feat(spend): add session inspection with bounded selected-request loading") to Settings > Usage & Spend > Sessions.
get_codex_session_details(sessionId, historyDays, checkpoint), backed byCodexWorkspacesIndex::load_session_detailsinrust/src/codex_workspaces/session_details.rs. It reads only the rollout files that belong to the selected session, inside the same history window as the summary. Nothing is read until a session is selected.limitExceededbeyond 5,000 requests or 256 MiB of rollout data (checked from file sizes before parsing), and the pane shows "Request details exceed the limit." It compares the result with the session summary (the checkpoint). If the logs changed since the summary was built, it fails withsourceChanged, and the pane shows "Request details are unavailable. Refresh usage and try again." An unknown session fails withunavailable.docs/CONFIGURATION.mddescribes the Sessions view.Differences from upstream:
