Sonnet 5 had disappeared from every surface: pi-ai 0.79.9 (the installed
version) lacks it, and FN-7374 removed the static row expecting the live
registry to carry it. Live-verified that claude-sonnet-5 returns 200 on
api.anthropic.com/v1 with a raw ANTHROPIC_API_KEY and runs via the Claude
CLI (it 403s on subscription-OAuth /v1 — scope-gated; runtime fallback
applies). Note: pi-ai 0.80.3 ships sonnet-5 natively, so this SUPPLEMENTAL
row dedupes once the install catches up.
- core: re-add claude-sonnet-5 to SUPPLEMENTAL_ANTHROPIC_PROVIDER_REGISTRATION
and restore its static pricing (revert FN-7374); update pricing tests.
- engine/dashboard tests: flip the FN-7374 "withheld" assertions to the
restored "advertised" behavior.
PR feedback:
- Trim the two FNXC comments (auth-storage.ts, pi.ts) to concise
requirement prose per coding guidelines (CodeRabbit).
- Replace the now-inert getApiKey mock in two subscription routing tests
with a clarifying note (Greptile).
