Gap analysis of docs/architecture.md against openspec/ and docs/ideas/
found the envisioned-but-uncaptured remainder. This commit captures it:
New OpenSpec change (validated):
- route-federation — the collaboration half of the federation vision:
routes as dereferenceable trails:Route objects, Create/Update
fan-out, Invite/Accept collaboration mirroring (arch decision #2),
cross-instance Planner edits via HTTP-Signature-requested scoped
tokens (decisions #3/#12), mirror sync healing (#16). Depends on
social-federation §6 + route-sharing; carries the 2026-06-07 soak
lessons as design constraints.
New docs/ideas/ explorations:
- instance-administration — registration toggle, suspend/ban,
federation blocklists, reports (moderation now gates the federated
comments idea)
- social-interactions — local likes + comments (don't exist even
locally; the foundation federated kudos/comments attach to)
- activity-participants — group tagging with confirm/decline +
federated mentions (the participants jsonb column is an untyped stub)
- multi-day-collections — architecture open question #1, directions
evaluated
architecture.md cleanup:
- Mastodon-compat section annotated with shipped/captured state + the
live-soak interop lessons (attachment arrays, tombstones, 10s
timeout, no backfill)
- api.trails.cool removed (contradicted resolved decision #18)
- Phase 1 ticked (shipped); Phase 2/3 items annotated with where each
is tracked; specs/ → openspec/, activity.* → journal.*, cx21 → cx23
- brouter-web open question marked resolved-in-practice; new section
pointing to where the unshipped vision is tracked

The 2026-06-07 disk-full outage (flagship 100%, postgres crash-looping
on its pidfile, prod + staging down): cd-apps DOES prune images after
deploys, but it had been failing early all day (migration bug), so its
prune never ran — while ~10 staging/preview deploys kept pulling fresh
images with no prune of their own.
- cd-staging: prune superseded layers (until=1h guard against racing
in-flight pulls) after persistent staging and preview deploys.
- disk-maintenance.yml: NEW daily scheduled prune (04:30 UTC) that
also FAILS when the disk is still ≥85% after pruning — a redundant
alert channel for exactly the case where the Grafana disk alert
drowns in other noise, as it did during the incident.

countFollowers counts every accepted follow row, but listFollowers
inner-joined users on follower_id — so a federated follower (NULL
follower_id, follower_actor_iri set) bumped the count while never
appearing in the list. Observed live: profile said '1 follower', list
below was empty. listFollowing had the same latent bug for outbound
trails-to-trails follows.
Both lists now left-join users + remote_actors: local entries link to
the local profile as before; remote entries display cached actor data
(IRI parsing as fallback) and link out to the remote profile.
Integration test pins count/list consistency for a remote follower.

The 0002 migration's allowed list predates the Komoot public-profile
connection mode (api.sync.komoot.verify.ts writes credentialKind
'public'). Against production data — which has such a connection —
the drop-then-add CHECK failed at ATRewriteTable and blocked every
cd-apps deploy since 2026-06-07 06:25 UTC.
Also documents 'public' in the schema comment with a pointer to keep
the two lists in sync.

Mastodon's PropertyValue parser requires the actor's attachment to be
a JSON *array* and silently ignores a bare object — and Fedify
compacts single-element arrays to bare objects, so the 🥾 trails.cool
field shipped in #464 never rendered (verified: Mastodon stored
fields = {} after a forced actor refresh on the soak instance).
Ship two fields so the array survives serialization: the 🥾 profile
link (rel=me) plus an Instance link — the latter is genuinely useful
for self-hosted instances anyway. Test now asserts the array shape
explicitly.

Caddy 2.9 deprecated the nested `servers { metrics }` form; every
deploy logs a deprecation warning. The global `metrics` option is the
replacement and emits the same Prometheus metrics on the admin
endpoint, so the existing scrape config is unaffected.
Validated with `caddy validate` against the caddy:2 image — config
valid, no deprecation warnings.

Hardening from two incidents on 2026-06-06/07:
Schema drift (morning): drizzle-kit push exits 0 even when it aborts
on an interactive prompt it can't render in CI, so cd-staging's
set -euo pipefail never fired and a month of staging schema drift
accumulated silently until new code hit missing columns. All three
drizzle push call sites now tee output and fail the deploy on any
'Error:' line.
Production outage (overnight, ~9h): cd-infra and cd-apps had no
failure handling at all. A network-option change stopped postgres for
a network recreation that then deadlocked on containers from other
compose projects holding trails-shared; the script carried on, the
stack stayed down. Both scripts now run set -euo pipefail and gate on
container health at the end (postgres+journal for cd-infra,
journal+planner for cd-apps) so a deploy that leaves the stack down
is a red X, not a shrug.
docs/deployment.md gains the cross-project manual procedure for
network-changing deploys — the CD workflows only manage their own
compose project and cannot apply those safely.

In production there are two copies of boss.server.ts in the process:
server.ts imports the TypeScript source directly (node
--experimental-strip-types) while route handlers live in the bundled
build/server/index.js with its own module instance. setBoss() from
server.ts wrote a module-local variable the bundle never saw, so EVERY
request-path enqueue failed with 'pg-boss not initialized' and was
swallowed by enqueueOptional's best-effort catch:
- notifications fan-out on activity publish: silently dropped
- komoot bulk-import kick-off: silently dropped
- federation activity push delivery: silently dropped (how we found
it — flipping an activity public on staging delivered nothing)
Dev never reproduces this: vite serves one module graph. Caught live
during the social-federation staging soak.
Fix: store the instance on globalThis under a Symbol.for() key so both
module copies resolve the same boss.

Follow-up to #466: staging and preview services attach only to the
externally-named trails-shared network (created by the production
compose project) — they have no per-project default network, so the
enable_ipv6 added to the staging file was dead config. Move the flag
to trails-shared where it takes effect.
Rollout requires recreating trails-shared on the flagship: detach
staging, previews, and production postgres, remove the network, re-up.
Production journal/planner are unaffected (they use the default
network).

The Notes we emit (outbox + push delivery) use /activities/{id} as
their id, but that URL only served HTML — so Mastodon's search-fetch
of an activity URL failed, and strict instances that re-fetch pushed
objects to verify them would drop our deliveries.
- Fedify object dispatcher for Note at /activities/{id}: serves the
same activityToNote mapping used everywhere else; 404 unless the
activity is public AND the owner's profile is public (private owners
don't federate, mirroring the actor).
- Content-negotiation middleware on the activity detail route, same
pattern as the actor route: AP Accept headers short-circuit to
Fedify, browsers get HTML.
Found during the staging soak (Mastodon showed the outbox post count
but couldn't fetch the posts).

The journal container could not reach v6-only fediverse instances
(e.g. social.ullrich.is) because the compose project network was
IPv4-only. The flagship host has working IPv6, and Docker >= 27
auto-allocates a ULA subnet with NAT66 masquerading when a network
sets enable_ipv6, so the fix is a one-line opt-in per network.
Applying it to an existing deployment requires recreating the
network (docker compose down && up -d) — a brief full-stack
restart on the flagship and the persistent staging project.
PR-preview networks are created fresh per PR and need nothing.

Mastodon gives inbox deliveries a 10s read timeout; without a queue,
Fedify runs inbox listeners AND outbound deliveries (the Accept we
push back after a Follow) inside the inbound request. A slow or
unreachable remote then blows the budget, the sender times out and
its circuit breaker (Stoplight on Mastodon) cuts us off — observed
live during the staging soak.
InProcessMessageQueue + manuallyStartQueue: the queue consumer starts
explicitly on first federation use (skipped under vitest so tests
don't leak timers). In-process queueing is acceptable for the
single-process journal: queued work lost on restart is recoverable
(remotes retry Follows; activity push delivery is owned by our own
pg-boss jobs). Revisit with a Postgres-backed MessageQueue if that
changes.

Mastodon renders PropertyValue attachments as the profile metadata
table — adds a '🥾 trails.cool' field linking to the user's canonical
profile, so it's human-visible that an account is a trails profile.
(The machine-readable signal stays NodeInfo; this is flair.) The link
carries rel=me so Mastodon can verify it once our HTML profile links
back.

Inbound Mastodon Follows are being rejected 401 (signature
verification) on staging and Fedify's diagnostics were invisible:
it logs through LogTape, which is silent until configured.
- Configure LogTape with a console sink for the 'fedify' category when
the federation instance is built; level via FEDERATION_LOG_LEVEL
(default info).
- Staging deploy sets FEDERATION_LOG_LEVEL=debug for the soak —
signature-verification detail per request; dial down once proven.

social-federation rollout step 12.2 — inbound soak. Persistent staging
gets FEDERATION_ENABLED=true; PR previews keep the flag empty so
preview journals never emit federation traffic.
- docker-compose.staging.yml: journal accepts FEDERATION_ENABLED +
FEDERATION_KEY_ENCRYPTION_KEY (both default empty).
- cd-staging.yml: persistent staging env sets FEDERATION_ENABLED=true;
the encryption key arrives via the existing SOPS decryption.
- secrets.app.env: new FEDERATION_KEY_ENCRYPTION_KEY (SOPS-encrypted,
generated with openssl rand -hex 32).
Production is unaffected: the flagship compose doesn't pass these vars
and the flag defaults off in code.

social-federation tasks 5.1–5.6. Completes the inbound-federation
story: a Mastodon follower now receives a trails user's new public
activities in their home timeline.
Outbox (5.1/5.2):
- /users/:username/outbox — paginated OrderedCollection of public
activities as Create(Note), newest first; unlisted/private never
federate. Private-user 404 enforced at the route layer because
Fedify builds collection-level responses from counter/cursors
without consulting the page dispatcher.
- Note shape: HTML content (escaped name/description/stats + link to
the activity page) with structured PropertyValue attachments
(distance-m, elevation-gain-m, duration-s) — Mastodon renders the
text, trails consumers read the structured fields. Resolves the
design open question toward Create(Note).
- Authorized Fetch: signed and unsigned outbox fetches deliberately
see the same (public-only) content until locked accounts exist.
Push delivery (5.3–5.6):
- createActivity / updateActivityVisibility(→public) enqueue one
deliver-activity job per accepted remote follower; flips away from
public and hard deletes enqueue Delete(Tombstone) retractions
(enqueued before the row disappears).
- deliver-activity job: re-reads the row at delivery time (skips if
gone or no longer public), resolves the recipient inbox via the
remote_actors cache with actor-document fetch fallback (priming the
cache), HTTP-signs via the owner's key, and POSTs. retryLimit 8 +
exponential backoff at enqueue time; outbound paced at 1 req/s per
remote host.
- Actor objects now advertise the outbox IRI.
- @js-temporal/polyfill added (same range Fedify uses) for published
timestamps; Fedify's types want the global esnext.temporal namespace,
bridged with a documented cast.
Tests: 9 unit tests for the AS mapping (escaping, stats, attachments,
published fallback, stable ids, tombstones), 4 outbox integration
tests (collection count, page shape/visibility filtering, private-404,
delivery audience query).

social-federation tasks 3.1–3.4, 4.1–4.8. With this, a Mastodon user
can follow a public trails user: WebFinger → actor fetch → signed
Follow → recorded + Accept(Follow) pushed back.
Identity surface (section 3):
- Actor objects now carry the user's public key (publicKey +
assertionMethods via Fedify key pairs dispatcher; keys generated
lazily as a fallback to the backfill) and an inbox IRI; url uses
localActorIri (3.1).
- Software discovery shipped as standard NodeInfo
(/.well-known/nodeinfo + /nodeinfo/2.1, software.name trails-cool)
instead of the originally-sketched custom AS actor field — Fedify's
typed vocab can't emit arbitrary actor props and NodeInfo is what
the fediverse reads. Artifacts updated accordingly (3.4).
Inbox (section 4):
- /users/:username/inbox resource route; HTTP Signatures verified by
Fedify before any listener runs (4.1). Rate-limited 60 req/5 min per
source instance (host from Signature keyId) BEFORE verification so
hostile instances can't burn CPU on key fetches (4.8).
- Listeners: Follow → auto-accept for public profiles + Accept pushed
back (4.2); Undo(Follow) → row removed (4.3); Accept(Follow) →
Pending settled + first outbox poll enqueued (4.4); Reject(Follow) →
Pending dropped (4.5; UI notice deferred to 6.6). Unhandled types
are acknowledged + dropped by Fedify (4.6).
- Replay protection via Fedify's KvStore, now Postgres-backed
(journal.federation_kv + daily sweep job) so dedupe survives
restarts (4.7).
Schema (discovered requirement):
- follows.follower_id relaxed to nullable + follows.follower_actor_iri
for inbound remote followers — the proposal's 'follows is already
federation-ready' only held for outbound. Check constraint enforces
exactly one follower identity; partial unique index dedupes remote
follows. Notification fan-out + approve flow now filter local
followers explicitly. Design/proposal updated.
Tests: 7 inbox integration tests (accept/refuse/idempotence/undo/
settle/reject/check-constraint), 6 KvStore integration tests, 2 unit
tests for source-host extraction. All against real Postgres, gated on
FEDERATION_INTEGRATION=1.

social-federation tasks 2.1–2.5:
- users.public_key / users.private_key_encrypted (TEXT NULL): RSA 2048
keypairs as JWK JSON; private key AES-256-GCM encrypted at rest with
FEDERATION_KEY_ENCRYPTION_KEY.
- remote_actors table: cache of remote AP actors (display fields,
inbox/outbox URLs, public key, software discovery field, poll cursor).
- activities.remote_origin_iri (UNIQUE) / remote_actor_iri / audience:
provenance + audience tagging for rows ingested from remote outboxes.
Replay-safe ingestion keys off the unique origin IRI.
- crypto.server.ts: generalized into createAesCipher(envVar, salt)
factory; existing INTEGRATION_SECRET surface unchanged.
- federation-keys.server.ts: generate/ensure/load keypairs.
RSASSA-PKCS1-v1_5 because that's what Mastodon interops on.
- backfill-user-keypairs pg-boss job: enqueued once per server startup
when FEDERATION_ENABLED=true; only touches users with NULL keys, so
re-runs are no-ops. New users get keys at registration (both passkey
and magic-link paths), best-effort with the backfill as safety net.
- design.md: noted open question — activities.owner_id is NOT NULL but
remote-ingested rows have no local owner; decide in task 7.2.
Schema is additive; zero behavior change while FEDERATION_ENABLED is
off. db:push verified clean against local Postgres.

social-federation tasks 1.1–1.3:
- Add @fedify/fedify pinned to exactly 2.1.16: every 2.2.x release
depends on @fedify/webfinger@2.2.x which was never published to npm,
so 2.1.16 is the newest installable version.
- app/lib/federation.server.ts: Federation instance with an actor
dispatcher serving Person objects for public users; private and
unknown users 404 (no existence leak). MemoryKvStore for now.
- /.well-known/webfinger resource route delegating to federation.fetch.
- ActivityPub content negotiation on /users/:username via route
middleware (future.v8_middleware — no loader uses the context arg,
so the flag is a no-op for existing code).
- FEDERATION_ENABLED env flag (default off) gating every federation
surface.
- Unit tests exercise the Fedify dispatcher as a remote AP client:
WebFinger resolution, actor fetch with Mastodon's Accept header,
private-user 404s, flag-off 404s.
Spike verdict: Fedify fits — URL dispatch, JRD/AP serialization, and
visibility gating all work through framework routes without a custom
server layer.

The roadmap claimed social-federation depends on route-sharing for
public routes, but that prerequisite shipped independently via
public-content-visibility (2026-04-24) and social-feed (2026-04-25):
visibility columns, public profiles, and IRI-keyed follows are all in
place. Reorder Phase 1 to reflect that federation can start now.
Also flag route-sharing's proposal as needing re-scoping: tasks
1.1-1.3 and 3.1 duplicate already-shipped visibility work, and the
proposed enum contradicts the shipped text-column design.
