/**
|
|
* Path B kill switch.
|
|
*
|
|
* GET /api/admin/path-b → returns { disabled: boolean }
|
|
* POST /api/admin/path-b/disable → sets disabled=true (handled below)
|
|
* POST /api/admin/path-b/enable → sets disabled=false
|
|
*
|
|
* Auth: Bearer NEXTAUTH_SECRET (ops bootstrap), same pattern as the
|
|
* /api/admin/backfill-isolation endpoint. We deliberately do NOT accept
|
|
* workspace API keys here — flipping a global feature flag is a
|
|
* platform-level action.
|
|
*
|
|
* When `path_b_disabled = true`:
|
|
* - shell.exec, fs.*, devcontainer.* return 503 from /api/mcp
|
|
* - the chat system prompt falls back to Path A (Gitea-write) guidance
|
|
* - existing dev containers keep running until they idle-suspend
|
|
* (no force-kill — graceful drain)
|
|
*
|
|
* Reverting is a single POST. Cache TTL is 10s, so the flip propagates
|
|
* to every Vibn pod within ~10s of the SQL update.
