app/: - bootstrap.ts 277 -> 145 lines: config guard, DB connect, client debug logging and startup order are now named steps with a comment header - lifecycle.ts (new): everything wired on the Discord 'ready' hook, in explicit order (inject broadcaster -> register listeners -> start workers) - process-guards.ts (new): SIGINT/SIGTERM/uncaughtException/unhandledRejection in ONE place, using isTransientStreamError() instead of two duplicated inline code lists - metrics-collector.ts (new): AI pipeline Prometheus gauges modules/: - ai-moderation/index.ts + message-capture/index.ts (new): public facades so app/ never reaches into internal files - aiAnalyzer.ts 317 -> 146 lines: pure entry API; skip-verdict recording extracted into recordSkip() - recovery-worker.ts (new): stranded-message recovery + stale lane/CB pruning - cache-prune.ts (new): 6h expired-verdict sweep, throttled + resettable - drop 3 dead re-exports (pickBatchWithinBudget/onCircuitBreakerAlert/ getConversationKey) whose consumers import the origin files directly No behavior change. typecheck + lint + 138 tests green; nix build OK.

/**

* Process-level signal + error guards.
|
|
*
|
|
* Extracted from bootstrap so the "what keeps the gateway alive vs what
|
|
* shuts it down" policy lives in exactly one place.
|
|
*
|
|
* Policy: transient stream-teardown failures (EPIPE / ERR_STREAM_DESTROYED /
|
|
* ERR_STREAM_WRITE_AFTER_END / ECONNRESET) are logged and IGNORED — crashing
|
|
* the gateway on them (voice stop/disconnect races, a child process stdin
|
|
* closed while we still write) takes the whole bot offline mid-operation.
|
|
* Anything else is a real bug: log with stack and shut down cleanly.
