fix(antigravity): group Claude 5.5 usage and derive reference prices

[lidge-jun]

Summary

Group known Antigravity Claude Sonnet/Opus 5.5 tier usage under their base model and show derived Anthropic reference cost estimates. Preserve discovered routing, saved selections and historical Claude 4.6 identity.

Selectively adapts #6497 (742bd6fa33f89fc66d112bafc93bf6753c62a52f) after #6501 landed. Static catalog replacement, inferred metadata and automatic 4.6 migration are excluded; source #6497 remains open. Relates to #6502: a bounded current-adapter request succeeded on one account, but the original Windows/multi-account cause is unproven. Shared JSON-equivalent registry normalization from 29a9e91f400d24ac746a18dfe3af357f5da6dec3 is carried with provenance; no other lane's auth runtime is included.

Verification

Current head: 8e963485612c5e90280f50cf059f1e51580ac189, including the reviewed prose-only follow-up.

• Cross-platform CI run 37132498856, attempt 1, event pull_request: success, including aggregate ci, all four test shards, gates, storage policy, API usage, Docker smoke, keyring Ubuntu/Windows, npm-global Ubuntu/Windows, docs and structure. Checkout log confirms tested merge SHA 7dd362385cce672735dbcb6b96d017de4453d5e6 = this head into dev e77bfb4901d405724edc4295caf5d9f0675a672e. Other applicable policy checks also succeeded; no unresolved review threads or maintainer change requests were observed at readiness.
• Platform test lanes, desktop/widget, setup-action/remote-helper, macOS-control and the separate privacy-only producer were deliberately skipped by workflow scope. These are not passing platform evidence; the runtime gates executed the privacy scan.
• Local: 368 pass / 0 fail across 13 focused files. New regression failed four cases before the fix and passed all five afterward. Both registry-only follow-ups preserved parsed mappings and passed 27 layout/file-size tests; no cap increased. Typecheck, structure, privacy and diff checks passed using the direct installed-Bun package-script entrypoints (bun node_modules/typescript/bin/tsc --noEmit, bun scripts/structure-ssot.ts, bun scripts/privacy-scan.ts) because the local npm Bun shim was not initialized by a scripts-disabled frozen install.
• Docs build: 561 pages / 77,929 internal links, passed.
• Independent implementation/security review PASS at runtime head 5d21f20f6e4cdf003c8d3a3833f76c109b445e02, including 5 new tests, 4 Google tests and 62 extra assertions for explicit tier/base prices, pooled providers, summary/day totals, zero overrides and immutability. Later deltas are JSON-equivalent registry changes only.
• Live baseline: official configured discovery returned all six Claude 5.5 tier IDs; the existing adapter returned HTTP 200/candidates for saved Sonnet 5.5-high with conflicting low effort while retaining the high wire. One account only; no account/config writes or installed-app replacement. No original Windows/multi-account issue-resolution claim.

Full-local-suite exception: concurrent stabilization worktrees share this workstation. An unrestricted import-graph run expanded to 1,490 files and ended 29,537 pass / 104 skip / 21 fail / 1 error, so it is not passing evidence. Five affected files pass independently. Baseline test bodies plus 12 byte-identical owning files reproduce an installed-Codex fixture EISDIR and test-wrapper service-authority mismatch; a complete baseline checkout was not tested and later lease timeouts remain untraced. No unrelated runtime patch was made. Applicable hosted current-head CI above passed independently.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Late planning-doc review: superseded publication prerequisites were removed, and the embedded original Ollama patch is clearly distinguished from the implemented deep-frozen regression linked in separate #6519 at commit917fa41229, test line589. Threads4173655800/4173655806 are resolved. No runtime/test changes; no product-test rerun for prose. Independent doc-interdiff review passed, both threads are resolved, and fresh exact-head CI37132498856 passed.

📝 Walkthrough

Walkthrough

The PR adds usage identity mappings and derived reference-price overlays for Antigravity Claude Sonnet and Opus 5.5 models. It adds tests and documentation, updates test-layout mappings, and records release coordination and an Ollama replay proposal.

Changes

Lane C release and usage work

Layer / File(s)	Summary
Release coordination and Ollama proposal devlog/_plan/261003_release_lane_c/000_plan.md, devlog/_plan/261003_release_lane_c/020_ollama.md, devlog/_plan/261003_release_lane_c/030_handoff.md	The Lane C plan and handoff define independent slice publication, verification requirements, and integrated review before deployment. The Ollama plan describes deferred assistant commentary while tool results remain outstanding and settlement of missing results. It does not change Ollama runtime code.
Antigravity Claude 5.5 usage accounting devlog/_plan/261003_release_lane_c/010_antigravity.md, src/providers/antigravity-models.ts, src/usage/expected-prices.ts	Known Claude Sonnet and Opus 5.5 base and tier IDs map to base usage identities. Eight expected-price overlays use Anthropic reference prices and are marked verified-derived. The plan records the scope and verification constraints.
Antigravity tests and documentation tests/usage/usage-antigravity-55.test.ts, tests/usage/usage-cost.test.ts, docs-site/src/content/docs/guides/providers.md, structure/dashboard-and-usage.md, structure/providers-and-adapters.md, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json	Tests cover canonical identities, estimated costs, aggregation, and unchanged historical or unknown identities. Documentation describes the usage identities and reference-price estimates. Test-layout mappings register the new test and revise other listed mappings.

Before / after behavior

• observed — Modified behavior in devlog/_plan/261003_release_lane_c/010_antigravity.md: The plan limits the runtime change to Antigravity usage identity mapping, retaining discovered-wire precedence, snapshot and partial-family behavior, and existing 4.6 identities. It specifies eight derived-price rows, cost-test membership and coverage updates, documentation edits, and a separate test file if the existing usage-summary file-size cap prevents additions.
• observed — Modified behavior in devlog/_plan/261003_release_lane_c/010_antigravity.md: The plan requires bounded discovery and, if available, a minimal request for the saved Sonnet 5.5-high selection; absent credentials or failed discovery/request leave #6502 unresolved. It excludes static fallback and routing migrations, defines normalization and isolation acceptance checks, lists focused tests and verification commands, and records source credit and the open status of #6497.
• observed — Modified behavior in devlog/_plan/261003_release_lane_c/010_antigravity.md: Execution notes record the prior roadmap decision to preserve routing, baseline verification results, and the usage-summary file-size constraint. They direct adding a sibling test with both layout registrations, record architect acceptance and additional cost/aggregation assertions, and specify literal totals for four requests per family while keeping historical and unknown IDs separate.
• observed — Modified behavior in devlog/_plan/261003_release_lane_c/010_antigravity.md: Adds the planned sibling test fixture for Sonnet and Opus 5.5. It checks deterministic base/tier identity, derived reference-price provenance and estimates across two provider IDs, model/day aggregation for tier and resolved IDs, and unchanged identities and prices for historical 4.6 and unknown suffixes.

Owner-authorized progressive maintainer integration into dev for the release stabilization train; this is an integration decision, not a self-approval.

I reviewed the scoped runtime delta and its consumers: only known Claude 5.5 usage identities and derived Anthropic reference estimates are added. Routing, saved selections, historical 4.6 identities and custom-price precedence are retained; these rows do not claim Antigravity billing prices or introduce a credential destination. Independent implementation/security review found no blocker and exercised the new aggregation cases plus additional synthetic assertions. The source author's pricing intent is credited. Static roster replacement and automatic 4.6 migration were deliberately not carried, so source #6497 is PARTIAL and remains open.

The broader local import-graph run was not green and is not represented as passing. Its isolated diagnostics are retained; required current-head hosted coverage is successful. Scoped local type, structure/privacy, docs and regression evidence is recorded in the PR. Live routing observation covers one existing account only, not the reporter's entire Windows/multi-account setup.

I reviewed the current integration base, including the native-upload, Ollama replay and Messages context-error changes. The pricing/usage identity runtime delta has no source overlap with those implementations; no routing, replay or error owner is replaced. The current merged tree passes the actual repository line-cap evaluator and parity of both test-layout maps. Its existing registrations are retained alongside the new usage regression. The conflict-free union check is bounded integration evidence, not a claim that an older CI run tested a newer base. Final independent integrated regression and full cross-platform CI still precede publication.

Live actor/dev target/head, required checks and unresolved review threads are checked immediately before landing. No unresolved maintainer objection is accepted.
