Problem

When Claude switches to a fallback model, T3 displays the notice but leaves the thread’s model selection unchanged. The picker shows the original model while Claude runs on the fallback model.

Change

Handle Claude’s explicit session model-change events and update the persisted thread selection through the existing model-selection event.

Preserve newer manual choices, gateway aliases, and local subagent selections. Keep model state accurate across resume and background continuations, including changes received before a continuation attaches.

Scope and approval

This fixes an observable inconsistency in existing Claude model-selection behavior. The adapter, ingestion, contract, documentation, and regression-test changes address that single mismatch.

Verification

307 focused tests passed, covering reselection, gateway aliases, resume, concurrent updates, and background continuations.
New regressions failed before their fixes and passed afterward.
Typecheck and formatting passed. Scoped lint reported no errors and one pre-existing warning.

Implemented with gpt-6.1-sol through the Codex harness.

Approvability

Verdict: Approved at 4fe5b03

Macroscope's review found this PR approvable — This is a focused fix for Claude fallback-model synchronization, with bounded changes to the adapter and event ingestion path and extensive regression coverage for resume, continuation, alias, and concurrency cases. The contract addition is optional and backward-compatible, and no product defaults or static-analysis configuration are changed.

Walkthrough

Claude fallback events update tracked model state and can publish a model-selection change to the app thread. The adapter handles live model changes, resumed queries, and continuations. The ingestor applies eligible updates under the app-thread lock.

Changes: Claude model fallback

Layer / File(s)	Summary
Track and publish Claude model selection `packages/provider-core/src/server/ProviderAdapter.ts`, `apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts`, `apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts`, `docs/user/providers-claude.md`	The provider event schema supports expected and next model selections. The adapter tracks current and followed selections, reports non-local fallback changes, and handles resumed sessions and continuations. Tests cover fallback frames, manual selections, aliases, and reverts. The documentation describes fallback behavior.
Apply provider model changes to app threads `apps/server/src/orchestration-v2/ProviderEventIngestor.ts`, `apps/server/src/orchestration-v2/ProviderEventIngestor.test.ts`	The ingestor applies a model-selection update when the active thread and expected selection match. It performs the update under the app-thread lock and retains rewind events. Tests cover selection checks and concurrent manual edits.

Estimated code review effort: 4 (Complex) | ~45 minutes

Possibly related issues

pingdotgg/t3code#24115 — The PR updates persisted thread selection from session fallback events, matching the issue’s stale picker and resumed-model concern.
pingdotgg/t3code#22265 — The PR changes live-model tracking used to decide when to call setModel, which overlaps with the issue’s concern about unnecessary calls and gateway models.
pingdotgg/t3code#27705 — The PR synchronizes fallback selection with stored state, but the issue’s initialization-time policy fallback and separate execution reporting are not established as covered.

Possibly related PRs

pingdotgg/t3code#22318 — Both changes use the Claude catalog in model-selection compilation and comparison.
pingdotgg/t3code#28024 — Both changes use catalog-compiled model IDs to track fallback and resumed model state.
pingdotgg/t3code#24126 — Both changes synchronize thread selection after Claude refusal fallback and preserve newer manual selections.

Note

Written by claude-opus-5-5 on behalf of Maria

merged current main without rebasing (11c5e66). the only conflict was in the model_refusal_fallback / notice branch of ClaudeAdapterV2.ts: main moved noticeTexts.add up and added the Stop-hook notice early return, and this pr adds the fallback model sync. both are kept, with the fallback sync running first so a fallback is never skipped. the import conflict keeps both modelSelectionsEqual and main's compareSemverVersions.

earlier rounds: 7c9deea and b616bce merged main and added NodeCrypto.layer to the downgrade tests; f4dda7e compiles the fallback revert check and resumed currentModel against the active catalog.

the coderabbit suggestion to add injected-catalog tests is not applied: it is extra coverage, not a defect, and would grow the pr.

blacksmith verification at 11c5e66: vp run check:changed against main passed format, lint, knip, graphql, typecheck (27 packages), and 407 tests (ClaudeAdapterV2.test.ts, ProviderEventIngestor.test.ts, AgentContextBudget.test.ts).

live claude fallback through the client after this merge is unverified: this vm has no claude authentication. the earlier live verification comment covers the pre-merge head.

Verified in a real dev environment

verified unchanged head 3b193e154758b4af1263e4b4a18ab38cd395e7a8 against github/main at ce9e01640636c0884c4a7574a722bf1d773cfa07 on this linux boat vm. installed dependencies with vp i on both revisions and ran one background vp run dev at a time with isolated state. drove the actual web client using the repo's playwright and /usr/bin/google-chrome. claude code v2.1.316 used the local provider proxy. no mocks, replay provider, injected events, or fixture writes.

created a project through the app pointing at a real git repository. real codex gpt-6.1-sol and claude sonnet 4.6 turns read its README using tools and returned its verification marker.
selected opus 5.5 and sent the same localhost-only, authorized CTF explanation request on both revisions. claude emitted a real session-scoped model_refusal_fallback from opus 5.5 to opus 4.8.
on main, the notice said opus 4.8 was answering while the picker and persisted thread stayed on opus 5.5.
on the pr, the picker, persisted thread, and provider metadata changed to opus 4.8. the native claude transcript confirms opus 4.8 produced the answer.
the following message kept opus 4.8. after stopping and restarting the dev server, reloaded the same thread and completed another tool-backed turn on opus 4.8.
manually restoring opus 5.5 reached claude and triggered another real opus 5.5 → opus 4.8 fallback; the picker followed it again. manually selecting sonnet 4.6 then completed a tool-backed turn on sonnet 4.6 without being overwritten.

short runtime transcript, from read-only projection and native provider transcript inspection:

blacksmith-check ran vp test run apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts apps/server/src/orchestration-v2/ProviderEventIngestor.test.ts: 330 tests passed. hosted checks report 28 successful, none failing or pending. no code changes were needed.

before, main retains opus 5.5 despite the opus 4.8 notice:

main keeps opus 5.5 after the real opus 4.8 fallback

after, the pr follows opus 4.8:

pr synchronizes the picker to the real opus 4.8 fallback

24-second recording of submission, live fallback, and the updated picker:

real claude fallback changes the picker from opus 5.5 to opus 4.8

Not verified

native ios/android and electron clients, macos/windows, relay/tunnel connections, gateway aliases, local subagent fallback, and background continuation races were not exercised live. this pass used the linux web client and the local proxy. alias, concurrency, and continuation coverage here comes from the existing focused tests, not live proof. provider-controlled revert/sticky events were not observed.

Use the active catalog when compiling model IDs.

A downloaded or scoped catalog can resolve an alias or suffix differently from the bundled catalog. A revert can then report the raw API ID instead of the selected model. On resume, the mismatch can also trigger an unnecessary setModel and applyFlagSettings.
