[Bug] Anthropic API Error: Auto mode classifier unavailable blocks Bash/Edit calls

Bug Description
Bug — Auto mode classifier unavailable (server-side) blocks all Bash and Edit calls; read-only tools still work · area: permissions / auto mode
▎
▎ What happened: Every Bash and Edit call began failing with The server-side auto mode classifier is temporarily unavailable (error)…. Read-only tools continued to work. Four consecutive retries of the same Edit over several minutes all failed identically. Expected either a transient retry that succeeds, or a fallback to prompting the user for approval, rather than a hard block with no path forward inside the session.
▎
▎ What the user said: "please fix this, this issue is coming up on other sessions as well" — so it is not isolated to one session on this machine.
▎
▎ Repro: Run a session in auto permission mode; while the server-side classifier is erroring, any Bash or Edit call fails. Read is unaffected. No in-session workaround is offered by the error text; the user must change permission mode.
▎
▎ Evidence: working directory ~/Documents/GitHub; blocked calls were an Edit to CLAUDE.md and a node -e walk via Bash. Failures 2026-09-28.
▎
▎ Suggestion: the error should name the workaround (switch off auto mode), since the classifier isn't reachable from the session — and a classifier outage arguably ought to degrade to "ask the user" rather than "refuse", which is the safe and available option.
