Short Description

Tightens instance auth so an inbound api_key is only ever treated as a client credential, never forwarded to Anthropic. Drops the old sk-ant- bring-your-own-key path.

Fixes #

Implementation Details

Previously an unknown sk-ant--shaped key was forwarded to the LLM as a bring-your-own key. That path is gone. An api_key now resolves one of four ways:

  • known client → swap in their stored Anthropic key
  • known client with a NULL stored key → 500 (server misconfig, reported to Sentry)
  • unknown key → 401, or 503 if the client store is unreachable (can't verify, so don't guess)
  • no api_key → global ANTHROPIC_API_KEY, else 401

Removed the forward KeyResolution tag and the shape check that went with it. Also trimmed a couple of log lines that were either routine or not actionable: the internal-token mismatch no longer reports to Sentry (it's a config/forgery signal, not a bug), and a max-staleness cache eviction no longer warns (happens whenever the DB lags). Tidied the comments in instance-auth.ts while I was in there.

An inbound api_key is now only ever a client credential, never forwarded
to the LLM:

- known client          -> swap in its stored Anthropic key
- known client, NULL key -> 500 (server misconfig, reported to Sentry)
- unknown key            -> 401 (verified unknown) / 503 (store unreachable)
- no api_key             -> global ANTHROPIC_API_KEY, else 401

Drops the sk-ant- shape check and the `forward` KeyResolution tag. Also
trims unactionable logging (internal-token mismatch and max-staleness
eviction no longer warn/report) and tidies comments in instance-auth.ts.
