refactor(cursor): canonical Claude-id normalizer replaces the three Fable 5.1 seeds - #3275
Conversation
…able 5.1 seeds Every Claude spelling Cursor has used (claude-fable-5-1, claude-fable-5.1, claude-5.1-fable, with -thinking/-fast/effort suffixes) resolves to one capability base; wire ids are composed back in the spelling the live GetUsableModels roster exposed, else the spelling the saved config used.

When Cursor discovery is in flight and clearModelCache(name) revokes its authority after a credential or configuration change, this call publishes the old roster before setCached(..., cacheGeneration) rejects it below. If a newer discovery finishes first, the stale request can even overwrite its spelling and leave requests emitting the previous account's Fable wire ID while the new catalog remains cached. Publish the spelling map only after the same generation check succeeds, or make it part of the generation-guarded cache update.
Useful? React with 👍 / 👎.

Fixed: both recordLiveCursorClaudeModels and recordLiveCursorMaxModeModels now run after setCached(..., cacheGeneration) accepts the capture, so a generation-revoked in-flight discovery cannot overwrite the newer roster's spelling.

When a configuration contains two named providers using adapter: "cursor", every successful discovery replaces this process-global map with its own roster, while resolveCursorSelection reads it without knowing which provider is handling the request. If the accounts expose different Fable spellings or marker orders, whichever discovery finishes last causes requests through the other provider to use an unsupported wire ID and receive ERROR_BAD_MODEL_NAME. Store the identities per provider/account and select the corresponding map in the request path.

Not changed here: a single process has one cursor adapter roster today, matching the existing liveCursorMaxModeBases precedent. Keying by provider name is recorded as the follow-up if a second Cursor-adapter provider ever ships (050 §risks).
