The metrics INFRA is already deployed (VictoriaMetrics scraping docmost:9464,
Grafana dashboards, alerts) with a target `gitmost-app` that is red because the
app half didn't exist. This is that half. The contract (metric names, port,
table, endpoint) is FIXED by the deployed infra and matched exactly.
Server (prom-client):
- A bare node:http `/metrics` server on METRICS_PORT (default 9464), SEPARATE
from the Fastify :3000 listener so /metrics never exists publicly; the whole
subsystem is OFF when METRICS_PORT is unset.
- collectDefaultMetrics() + http_request_duration_seconds{method,route,status}
via a Fastify onResponse hook using the ROUTE TEMPLATE (req.routeOptions.url,
never the raw URL — bounded cardinality; 404 -> "unknown"), EXCLUDING SSE/
streaming responses (would record the connection lifetime and poison p95).
- db_query_duration_seconds (Kysely log callback, labelled by the leading SQL
token), bullmq_queue_depth{queue} (getJobCounts every 15s) +
bullmq_job_duration_seconds{queue} (worker completed/failed),
collab_store_duration_seconds (around onStoreDocument).
- POST /api/telemetry/vitals — PUBLIC (sendBeacon) but IP-throttled; ~16KB body
cap, <=50 events/batch, metric-name + rating whitelist, attr truncated to 120
chars, batch insert; malformed/foreign/oversized silently dropped and 200'd (no
browser retry). New migration `client_metrics` (schema byte-identical to the
contract, both indexes, conditional grafana_ro GRANT; no app-side retention —
the maintenance container prunes >90d).
Client (web-vitals):
- initVitals() decides sampling ONCE per session (25%, sessionStorage) BEFORE
subscribing; onINP/onLCP/onCLS/onTTFB (attribution) buffered + flushed via
navigator.sendBeacon on visibilitychange:hidden and a timer (not fetch-per-
metric). Custom: editor_tx_ms (dispatchTransaction sync-part timer, >8ms, with
doc_size), page_open_ms, longtask_ms. Route labels are templates only; no
titles/slugs/text.
Gate: server + client tsc 0, frozen install 0 (added prom-client + web-vitals +
regenerated the lock), server metrics/vitals tests 11, client route-template 5,
and the migration verified valid against real Postgres.

The full-AppModule e2e (apps/server/test/app.e2e-spec.ts) passed but jest
never exited, burning CI to its timeout. Diagnosis (process._getActiveHandles
after app.close()) showed exactly two ioredis sockets to :6379 still open after
shutdown; everything else (BullMQ queues/workers, @nestjs/schedule intervals,
nestjs-ioredis, nestjs-kysely pg pool, @nestjs/cache-manager Keyv store,
hocuspocus pub/sub) already closes on app.close().
The two leaks were owned-but-never-closed clients:
1. ThrottleModule passed a pre-built `new Redis(...)` instance to
ThrottlerStorageRedisService. With an instance, the lib sets
disconnectRequired=false, so its onModuleDestroy never disconnects.
Pass ioredis options instead so the service owns + disconnects the client.
2. CollaborationGateway created a source `new RedisClient(...)` that
RedisSyncExtension only duplicates into pub/sub; the extension's onDestroy
disconnects those duplicates but not the source. Keep a reference and
disconnect it after the hocuspocus onDestroy hook in destroy().
Both are real lifecycle fixes (production shutdown is now clean too), so no
--forceExit is needed. Verified against real Postgres+Redis:
- test:e2e (no forceExit, --runInBand) exits 0 in ~18s (was: hung forever)
- --detectOpenHandles exits 0 with no open-handle report
- active handles after app.close(): none
CI timeout-minutes safety nets left untouched.

Release-cycle review: POST /pages/template/lookup had only JwtAuthGuard and the
embed depth cap was client-only, so a scripted client could drive heavy
full-content fan-out (access control holds per-id, but a cost/DoS gap). And
page_template_references rows were written for any sourcePageId with no
workspace check at sync time (no leak today since lookup re-checks access, but
the graph could accumulate cross-space rows).
- Apply the standard per-user throttler (PAGE_TEMPLATE_THROTTLER, 30/min) to
/pages/template/lookup and /pages/toggle-template (mirrors ai-chat); auth +
the toggle's validateCanEdit CASL are unchanged.
- syncPageTemplateReferences / insertTemplateReferencesForPages now restrict
inserts to in-workspace source ids (filterInWorkspaceSourceIds, workspace +
not-deleted scoped, trx-aware) and still delete stale out-of-workspace rows
(self-heal). SECURITY comment: the ref table is NOT access-filtered; every
consumer must permission-filter at read time (as lookupTemplate does).
- Tests: lookup access exercises the REAL filterViewerAccessiblePageIds
(no_access / cross-workspace excluded / accessible+comment-stripped / <=50);
toggle controller CASL (cannot-edit -> Forbidden, flag not flipped); ref-sync
excludes cross-workspace and keeps in-workspace.

Lets an unauthenticated viewer of a published share ask an AI scoped strictly
to that share's page tree. The authenticated agent is untouched; the security
boundary is the tool scope (no identity), and nothing is persisted.
Server:
- workspace toggle settings.ai.publicShareAssistant (default off) +
optional settings.ai.provider.publicShareChatModel (cheap model id; reuses
the chat driver/baseUrl/key). getChatModel(workspaceId, override) substitutes
only the model id, falling back to chatModel.
- POST /api/shares/ai/stream (@Public, SSE). Guardrail funnel, each failing
before streaming: toggle off -> 404; share missing/wrong-workspace/sharing
off -> 404; pageId not in share tree -> 404; provider unconfigured -> 503;
per-IP (5/min) and per-workspace (300/h, IP-independent) rate limits -> 429.
Uniform 404s never confirm a private page's existence.
- forShare read-only in-process toolset: searchSharePages (existing shareId
FTS branch, no spaceId/userId), getSharePage (getShareForPage gate +
share.id check, content via the public sanitizer), listSharePages. No write/
comment/history/cross-space/external-MCP tools.
- Locked share system prompt + immutable safety block; stepCountIs(5).
- /shares/page-info exposes an aiAssistant flag (gated behind isSharingAllowed).
Client: an ephemeral, text-only Ask-AI widget on the public shared page,
shown only when the flag is set; useChat -> /api/shares/ai/stream,
credentials omit. Admin toggle + model field in Settings -> AI.
Also adds a jest moduleNameMapper for src/-rooted imports (fixes pre-existing
unresolvable specs; additive).
Implements docs/public-share-assistant-plan.md.
