Price ChatGPT Auto-review requests at zero

[Finesssee]

Summary

Port of upstream steipete#4452 / steipete#4453 (v0.75.0). ChatGPT-plan codex-auto-review requests at or after 2026-10-06T07:00Z are included in the plan and priced at $0; tokens stay in totals.

• Rule: request on/after the cutoff, in a rollout whose session_meta has a non-blank payload.creator_account_id → $0. Pre-cutoff and API-key rollouts stay unpriced (Partial). An explicit custom price for codex-auto-review wins; models.dev/bundled prices never apply.
• core/codex_included_pricing.rs (new): cutoff, eligibility, mark_included_records (re-keys to codex-auto-review-included at parse time, since Windows aggregates per day/model).
• Applied on resumed-append, full-parse, and source-row paths; priced at Some(0.0) in the Codex pricing core; summary shows it as codex-auto-review at $0 without Partial.
• CODEX_CACHE_SCHEMA_VERSION 6 → 7 so caches rebuild.
• CHANGELOG line.

Known gap: codex_workspaces/indexer.rs sidecar has no creator info, so included requests there remain unpriced.

Commands

• cargo test --manifest-path rust/Cargo.toml (4499 lib pass after merging main)
• cargo test --manifest-path apps/desktop-tauri/src-tauri/Cargo.toml (721 pass)
• cargo clippy both manifests --all-targets -- -D warnings, cargo fmt --all -- --check

UI proof

Backend pricing only; no frontend change. Covered by scanner/pricing tests; no CUA run.

Summary by CodeRabbit

📝 Walkthrough

Codex Auto-review requests from eligible ChatGPT-created sessions are classified as included from the 2026-10-06 cutoff. Their tokens remain in totals, and their cost is zero unless explicit custom pricing applies.

Changes: Codex Auto-review pricing

Layer / File(s)	Summary
Eligibility and included-record classification rust/src/core/jsonl_scanner.rs, rust/src/core/jsonl_scanner/codex.rs, rust/src/core/codex_included_pricing.rs, rust/src/core/jsonl_scanner/codex/source_rows.rs, rust/src/core/jsonl_scanner/tests.rs, rust/src/core/jsonl_scanner/tests/codex_metadata.rs, rust/src/core/mod.rs	Session metadata records whether creator_account_id is a non-blank string. Eligible Auto-review requests receive the codex-auto-review-included key. The Codex cache schema version increases to 7.
Codex scanner integration rust/src/cost_scanner/codex.rs, rust/src/cost_scanner/tests.rs, rust/src/cost_scanner/tests/codex_auto_review.rs	Both scanner parse paths mark records using creator-account metadata. Tests cover eligible and ineligible sessions, cutoff timing, token totals, and pricing completeness.
Zero-cost pricing and summary output rust/src/core/cost_pricing/codex.rs, rust/src/codex_costs.rs, rust/src/spend_contract/tests.rs, CHANGELOG.md	Included model keys receive zero-cost pricing and their tokens remain in summaries. Custom model pricing remains applicable. The changelog records the pricing rule.

Merge Risk: 🔵 Low · up to 5e4c2

Codex Auto-review requests from ChatGPT-created sessions are now priced at zero from the cutoff. The changelog does not state the 07:00 UTC boundary. No functional risk remains, so this is safe to merge after a small wording fix.

Full details: Ui Changes Include Windows Proof

Explanation

The PR changes user-visible spend output. The diff makes eligible Auto-review usage appear as $0, retains its tokens, and removes the Partial/unpriced state in rust/src/codex_costs.rs; the spend contract exposes these values to the desktop Usage & Spend views. The description reports backend tests and explicitly says “no CUA run,” but it includes no screenshot or proof note from a fresh Windows build.
