DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.228

Bootstrap responses are thrown away if the credential changed mid-flight

You'll notice
Useful3 Signal3
Auth

Startup config from an old account is discarded if you switched credentials mid-request.

What

After the startup configuration fetch returns, Claude Code re-checks which credential is active; if it changed while the request was in flight, the response is discarded instead of applied, so a stale account's settings cannot land on the new one.

Details
  • Logs [Bootstrap] Discarding response fetched under a superseded credential.
  • Records the reason superseded_credential on the bootstrap fetch event.
Evidence

superseded_credential

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
