Summary

Ports upstream CodexBar v0.75.0 cost CLI changes: identified-request subtotals (steipete#4447; fa2b14e, d3724b2) and the project-report partial-history notice (steipete#4472; 8ec6033). Flag names and help match upstream CLICostCommand.swift / CLIHelp.swift.

  • cost --provider codex --format json --identified-only [--days N] [--identified-end <unix-ms>] [--remote <host>]: opt-in native Codex identified-request subtotal. It uses upstream's versioned ledger fields, length-framed SHA-256 request IDs, a UTC-midnight window, a 50,000-record cap and overflow checks. Merging removes duplicates and keeps conflicting requests excluded. costUSD is always null (no estimated combined price). It rejects non-JSON output, a non-codex provider, period flags, --group-by, --summary-only and a day count outside 1–365.
    • Local scan covers sessions and archived_sessions. A request counts only in the session file that owns it, and copies of the parent's requests in a forked file are not double-counted. Malformed lines or a file that changes during the scan mark the result partial.
    • --remote runs the same export over the existing SSH safeguards (32 MiB output cap). If the remote fails, the explicitly partial local subtotal is kept, and the exit code is nonzero.
  • cost --group-by project (text): lists projects from the Codex workspaces index and respects hide-personal-info. When history coverage is incomplete, the coverage notice comes first, including when the project list is empty. If project history can't be loaded, it prints "Project history unavailable: …".
  • docs/CLI.md updated.

Not ported: upstream's cancellation handling during export, and the parser-hash/cache hooks (the identified scan is a standalone module). Fork ownership is decided by session ID only. The desktop UI is unchanged.

Tests

  • cargo test --manifest-path rust/Cargo.toml: 4634 passed, 0 failed (after merging main)
  • clippy -D warnings on both manifests: clean
  • New codex_costs::identified_requests tests (ledger validation, dedupe/conflicts, ownership, forks, partial cases) plus CLI argument tests.
  • Smoke on real local history: --identified-only --days 7 → 1007 records, 0 excluded, not partial, exit 0; non-JSON --identified-only → argument error; --group-by project --days 7 → coverage notice + projects.

Summary by CodeRabbit

  • New Features
    • Added project-grouped cost reports for Codex, including token usage and available project paths.
    • Added an experimental --identified-only option to export a versioned ledger of identified Codex requests for a UTC time window, with optional separate SSH-host results and a subtotal.
  • Improvements
    • Identified-request exports deduplicate matching requests across sources, retain available results when a source is incomplete, and do not estimate combined pricing.
    • Cost reports indicate when history or project coverage is incomplete, including when no projects are listed.
    • Project reports can hide project names and paths.

📝 Walkthrough

The cost command adds Codex project-grouped text reports and an identified-request JSON mode. Identified usage can include local and optional SSH history, with deduplication, validation, and partial-result reporting. The CLI documentation and Windows changelog describe these options.

Project-grouped cost reports now handle other providers correctly. They also warn about incomplete workspace history before the project list, even when no projects are listed. No outstanding merge-blocking issues were identified.

Full details: Provider Data Stays Siloed

Explanation

The prior failure remains unresolved. The PR adds Codex-specific branching in shared rust/src/cli/cost.rs, outside rust/src/providers/&lt;name&gt;/ and rust/src/core/provider_factory.rs: identified usage dispatch matches the raw "codex" provider at lines 127-143, and project output selects result.provider == "codex" at lines 376-379. The base revision has neither new branch. These branches match one provider in shared code and meet the explicit failure condition.

Resolution

Move identified-usage dispatch and project-report rendering behind a provider-specific Codex adapter or factory capability. Remove the direct "codex" checks from shared rust/src/cli/cost.rs; use typed provider capabilities or provider-owned handlers instead.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Handle project grouping before token-history output.

If the selected provider is Antigravity or Muse, token_history is present and the earlier branch prints token history instead of this not-available line. The requested project grouping is silently ignored. Check project grouping before token_history, so every non-Codex provider receives the documented response.

Report partial workspace history before the project list.

If snapshot.source_status.is_partial() but the cost scan has established coverage, this branch emits no partial-history notice. The project list can then appear complete even though workspace indexing omitted history. Check source_status before rendering the list, including when snapshot.projects is empty. The session renderer already checks this status.

🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Skip session files whose modification time is before the window start.

load_ledger_from_roots reads every *.jsonl file under sessions and archived_sessions from start to end. The --days window does not affect this, and the maximum window is 365 days. A record can enter the ledger only when its timestamp is at or after start_unix_ms. A file's modification time is at or after the time of its last write. So a file last modified before start_unix_ms cannot contribute a record, a conflict, or a legacy exclusion.

This matters most on the remote path. codex_cli_options sets a fixed 60-second SSH timeout. A full history scan on a large remote host can exceed that timeout. The remote source then reports "unavailable", even when the window is short.

To fix this, skip files with an old modification time before calling scan_file. Keep a margin for clock skew.

Addressed all three findings:

  1. cost.rs:381 (project grouping vs token history): project grouping is now checked before token history, so Antigravity/Muse with --group-by project get the "only available for Codex" line instead of silently printing token history.
  2. cost.rs:600 (partial workspace history): the partial-history notice now also appears when the workspace catalog's source_status is partial (catalog missing/locked/corrupt/incompatible), even if cost coverage is established and the list is empty. It is printed once. Added a test with a locked catalog.
  3. identified_requests.rs:419 (mtime skip): files whose modification time is more than one day (clock-skew margin) before the window start are skipped before scan_file. Unreadable metadata keeps the file. Added a test for skip outside the margin and scan inside it.

identified_requests 19 passed, cli::cost 30 passed, clippy clean. After merging main: full cargo test 4647 passed, 1 failed. The failure is token_activity::codex_activity_leaves_the_shared_cost_coverage_alone, which also fails on main (time-zone bug in the test only, unrelated to this PR); fixed separately.

On the "Provider Data Stays Siloed" pre-merge check: the cost CLI is Codex-centric by design, matching upstream's CostCommand. rust/src/cli/cost.rs on main already branches on "codex" for session grouping, coverage notices, and the JSON contract fields. This PR follows that same pattern for --group-by project and identified-request subtotals.

No provider data crosses between providers here. Project and identified-request output only render for Codex results, and other providers get the explicit "only available for Codex" notice. Moving cost-report dispatch behind a typed provider capability would touch the whole command, so it is out of scope for this port. I'm tracking it as a follow-up refactor.
