Follow-up to #4930, for Claude only, as suggested there. The Pi version is #5025.

What it does

1. codexbar cost --provider claude --group-by session and --group-by project now work.
2. The Cost menu and Usage & Spend show Claude projects and conversations, like Codex.
3. A project is the session's cwd. A conversation shows its short session id, as Codex text output does.
4. JSON cost output now includes Claude projects[]. Like Codex, it has no per-session rows.
5. Vertex AI is unchanged.

How it works

• Attribution comes from the rows the scanner already reconciles. Each winning row (after the existing message and request dedup, and the sidechain and subagent rules) belongs to its sessionId. Sessions and projects are built from those same rows, so they add up to the Claude total.
• Each session keeps its own first cwd, even when one file holds several sessions.
• Appends start from the cached cwd map. A full parse or a forced rescan rebuilds it.
• The cache artifact moves to v6, so history rebuilds once from the transcripts. Older report memos still decode and rebuild their breakdowns once.
• Breakdowns are saved in the report memo, so a relaunch does not decode the full cache again.
• When Pi rows are merged into Claude, Claude shows Pi as one "Unknown project" row and no conversations, the same as Codex today.

Cost

Benchmarks against main, debug build, 3 interleaved rounds:

• Full rebuild, 5,000 files and 250k rows: 2.85 s on main, 3.29 s on this branch (+15%).
• Refresh after an append, 24k rows: about +0.075 s per refresh.
• Session and project reports skip the hourly and quota buckets, so each row is priced at most 3 times.

Tests

All fixtures are synthetic.

• Ownership: rows go to the right session and project, and the sums match the total.
• Two sessions in one file get separate projects.
• Append, rewrite, a response copied across resumed transcripts, and sidechain and subagent copies.
• Cache upgrade to v6, and a relaunch that restores breakdowns without decoding the cache.
• An unpriced day stays unpriced in every group.
• CLI text and JSON for both groupings.

Codex review: needs real behavior proof before merge.

What this changes

This PR adds Claude session and project cost breakdowns to CLI output, the Cost menu, and Usage & Spend.

Example: Inspect session-alpha with 110 recorded tokens under /Users/test/projects/alpha.

• Before: Claude session grouping is skipped because only Codex supports it.
• After: Claude session grouping lists session-alpha, and project grouping attributes its usage to alpha.

Review scores

Measure	Result	What it means

Product

Kind: Feature · Worth it: Needs a maintainer decision · Fix scope: Partial
User problem: Users can inspect aggregate Claude costs but cannot identify each conversation’s or project’s contribution through the existing grouped views.
Reason: The implementation supplies the focused Claude contribution requested for reconsideration in #4930, while Pi and optional task aggregation remain outside its scope.

Merge readiness

⛔ Blocked before merge - 4 items remain

Keep this PR open: it delivers a distinct Claude capability invited for reconsideration, but grouped output loses an established incomplete-usage warning and the feature still needs an owner decision.

Priority: P2
Reviewed head: 914377c665799bde474836ee9f563f19f2d21b91
Owner decision: Required. See Decision needed.

Decision needed

• Question: Should Claude session/project breakdowns ship with persisted working-directory attribution and a one-time Claude/Vertex cache rebuild?
• Recommendation: Accept the focused Claude feature: Approve the direction, with the correctness finding and contributor proof gates resolved before merge.
• Why: The owner invited a focused implementation for reconsideration but has not approved this implementation or its storage and performance tradeoffs.

Before merge

• Add real behavior proof - The supplied evidence exercises scanner, fetcher, and rendering code through synthetic tests and benchmarks, but shows no shipped CLI output or app capture demonstrating Claude project/conversation attribution after the change; provide redacted terminal output and screenshots or a recording, removing API keys, IPs, and non-public endpoints. After adding proof, update the PR body, then request a new review with @clawsweeper re-review. The PR author or someone with repository write access can request it.
• Preserve incomplete-usage warnings in Claude grouped reports (P2) - With one completed Claude response and one preliminary proxy response (stop_reason: null, positive input, zero output, and no cache counters), the scanner excludes the preliminary response and retains an incomplete-request count. Enabling Claude in these early-return branches bypasses the existing exclusion warning below, and neither grouped renderer reads that count. Both --group-by session and --group-by project therefore present the completed-response subtotal without disclosing the missing usage, contrary to the established contract in fix(cost): avoid pricing incomplete Claude proxy usage #3688. Carry the existing incomplete/unpriced notices into grouped output and add a mixed completed/preliminary regression.
• Add data-model compatibility proof - The review found that existing stored data may not work after upgrade. Show that existing data still loads and works with this change.
• Explain or restore the original intent of Incomplete Claude usage presentation - fix(cost): avoid pricing incomplete Claude proxy usage #3688: Exclude preliminary proxy requests while clearly marking remaining known amounts as partial subtotals across user-facing reports.

Findings

• [P2] Preserve incomplete-usage warnings in Claude grouped reports — Sources/CodexBarCLI/CLICostCommand.swift:213-220

Provenance

• Incomplete Claude usage presentation changes intended behavior without addressing why it exists (fix(cost): avoid pricing incomplete Claude proxy usage #3688: Exclude preliminary proxy requests while clearly marking remaining known amounts as partial subtotals across user-facing reports.)

Tests

• Missing end-to-end proof: Supply shipped CLI and app results for Claude grouping, including incomplete usage, plus a latest-stable upgrade with existing state preserved; the new warning regression has no demonstrated base-fail/head-pass run.

Agent review details

How this fits together

The local cost scanner reads Claude transcripts, reconciles duplicate usage records, persists generated caches, and supplies estimated costs to the CLI and app views.

Technical review

Best possible solution:

Use the existing scanner and presentation owners for Claude breakdowns while preserving incomplete and unpriced subtotal warnings in grouped output.

Do we have a high-confidence way to reproduce the issue?

Current-main provider filtering and tests establish that Claude grouped text output is unavailable; source inspection also establishes the introduced warning bypass without executing target code.

Is this the best way to solve the issue?

Partitioning existing reconciled rows into existing breakdown models is appropriate, but reusing the Codex renderers must preserve Claude’s incomplete-usage contract.

Codex review notes: model internal, reasoning medium; reviewed against 7447bc77c249.

Provenance checked

• CLI grouping and native-only session accounting changes intended behavior with a stated reason (feat(cli): add Codex session cost grouping #2854: Expose native Codex conversations while explicitly omitting Pi/OMP aggregates from session-grouped text output.)
• Claude reconciliation keeps the original intent (8959d1c: Reconcile duplicate rows by reference without copying complete row buffers.)
• Generated cache and persisted report reuse changes intended behavior with a stated reason (fix(cost): compact and reuse Claude cache artifacts #4092: Reuse compatible generated artifacts and avoid repeated full-history decoding and encoding.)
• Hosted submenu fingerprints keeps the original intent (perf: match cost history fingerprint to visible content #2067: Invalidate hosted menus only for rendered project, source, session, and chart content.)

Testing

Security

None.

Evidence

What I checked:

• Maintainer invited a focused implementation: In Cost per session for Claude and Pi, like Codex has #4930 (comment), steipete invited a single-provider implementation with synthetic ownership and append/update coverage as a basis for reconsideration; this was conditional reconsideration, not approval to ship.
• Introduced changes verified: The pinned introduced diff adds Claude attribution using existing reconciled winners and existing breakdown models; main still restricts grouped text output to Codex. (Sources/CodexBarCore/Vendored/CostUsage/CostUsageScanner+ClaudeProjects.swift:116, 914377c66579)
• Grouped output bypasses exclusion warnings: Both newly enabled Claude grouping branches return before incomplete and unpriced request counts are computed; their renderers print amounts without those warnings. (Sources/CodexBarCLI/CLICostCommand.swift:213, 914377c66579)
• Established partial-subtotal contract: fix(cost): avoid pricing incomplete Claude proxy usage #3688 explicitly requires known Claude usage to remain a clearly marked subtotal when preliminary proxy requests lack final usage. (Sources/CodexBarCore/Vendored/CostUsage/CostUsageScanner+Claude.swift:239, 2d9334237e7c)
• Cache upgrade has synthetic coverage: The generated Claude/Vertex cache schema advances from 5 to 6; the added test downgrades a newly generated synthetic cache and verifies reparsing and restored attribution. (Tests/CodexBarTests/CostUsageScannerClaudeCacheUpgradeTests.swift:517, 914377c66579)
• Full supplied proof inspected: The full REST body and discussion match the supplied context identity bc2412413989eb11fbb55de31dcd4ff7ab3fdb256ae8d86d2d429958fb72b486 and describe synthetic tests and benchmarks, without recordings, screenshots, terminal results, or logs exercising the changed shipped behavior.

Real behavior proof, from the CLI built from this branch (head b8b066983).

Setup:

• 4 synthetic Claude Code transcripts in 3 projects, made by a small script. No real transcripts.
• A throwaway home folder (HOME and CFFIXED_USER_HOME), so the real cache stays untouched.
• Times are UTC.

1. Upgrade from 0.81.0

CodexBar 0.81.0 ran first on the same home and built its Claude cache. Then the branch build ran:

0.81.0  $ codexbar cost --provider claude
Today: $0.24 · 235K tokens
Last 30 days: $0.24 · 235K tokens

branch  $ codexbar cost --provider claude
Today: $0.24 · 235K tokens
Last 30 days: $0.24 · 235K tokens

The totals match.

2. Sessions and projects

$ codexbar cost --provider claude --group-by session
Conversations (Last 30 days):
Session f6f6...00000004: $0.02 · 24K tokens · 1 requests
claude-sonnet-4-5 · Nov 8, 11:52
Session e5e5...00000003: $0.10 · 94K tokens · 4 requests
claude-sonnet-4-5 · Nov 8, 11:22
Session d4d4...00000002: $0.05 · 47K tokens · 2 requests
claude-sonnet-4-5 · Nov 8, 10:02
Session d4d4...00000001: $0.07 · 70K tokens · 3 requests
claude-sonnet-4-5 · Nov 8, 09:12

$ codexbar cost --provider claude --group-by project
Projects (Last 30 days):
alpha: $0.12 · 118K tokens
  /Users/test/projects/alpha
beta: $0.10 · 94K tokens
  /Users/test/projects/beta
gamma: $0.02 · 24K tokens
  /Users/test/projects/gamma

The projects add up to the $0.24 total. Each session's time is its last reply.

3. Append

I appended 2 replies to session d4d4...0001:

$ codexbar cost --provider claude --group-by session --refresh
Session d4d4...00000001: $0.12 · 118K tokens · 5 requests
claude-sonnet-4-5 · Nov 8, 14:48
(other 3 sessions unchanged)

$ codexbar cost --provider claude --group-by project
alpha: $0.17 · 164K tokens
beta: $0.10 · 94K tokens
gamma: $0.02 · 24K tokens

Only that session and its project changed. The new total, $0.29, equals the sum of the projects.

The session view also prints the existing "Pi/OMP usage is omitted" warning, because the default run can merge Pi rows into Claude.

Preserve incomplete-usage warnings in Claude grouped reports

When Claude logs contain both completed usage and a proxy request lacking final usage, these new grouped paths return before the incompleteRequestCount warning logic. Neither grouped renderer checks that count, while a fully parsed transcript still has historyIsFullyScanned == true, so --group-by session and --group-by project show completed-only cost/token subtotals without any Incomplete marker; the default report correctly warns for the same snapshot. Carry the incomplete-usage notice into grouped output, or mark affected groups, so users can tell these amounts exclude known requests.
