Since #12667, a present error code short-circuits classification: a code that is genuinely transient but missing from `RECOVERABLE_CODES` classifies as FATAL. That is the shape that dead-ends terminal panes — #12650 fixed exactly that for a different error, where a transient failure misclassified as fatal unmounted the Reconnect banner and left recreating the session as the only escape. Today the code and fragment sets agree. Nothing prevented a future code from being added without a matching entry, and the failure would have been silent. This pins that agreement: for every reachable transport error, a code that classifies fatal must not carry a message that would have classified recoverable. 57 coded pairs plus 8 code-less ones, derived by invoking the producers where possible so a reworded message updates the corpus instead of leaving a stale copy silently passing. The failure message names the offending fragment and says what to do about it. Enumeration turned up producers beyond the obvious ones — notably the Tailscale-hinted variants, where `runtime-environment-transport-routing.ts` mutates the message on an already-coded error before it crosses IPC, making those distinct corpus members. Also documented (not asserted, because it is unreachable today): `runtime_rpc_queue_overloaded` is absent from both host passthrough allowlists, so if it ever crossed `mapRuntimeError` it would flatten to `runtime_error` while keeping its "queue is full" message — precisely the dangerous shape. The queue pool is never instantiated on the server dispatcher, so it cannot happen now. The known exception is pinned rather than silently exempted: a dedicated test records WHY the guard cannot see `remote_runtime_busy` (fatal by code, matching no fragment, so the two sides have nothing to disagree about). If someone rewords a busy message into connection wording, that test fails and points at STA-3479. Proven non-vacuous by four separate injections. The only production change is two `const` to `export const`.
