last_seen means "this user did something recently". The backfill walks every
historical record in the network, so stamping it there recorded when the
backfill ran, not when the user was active — for every user at once, on every
run. That destroys the only signal the column carries, and it is the one column
in users that nothing upstream can rebuild.
It is now written on the two paths that represent real activity: an interactive
login, and a live commit event on the firehose, which does mean the user just
wrote a record. The backfill still corrects handle, PDS endpoint and avatar,
which is why it re-resolves rather than trusting a cache; it just no longer
claims the user was present.
UpsertUser grows an options form rather than a fourth named variant, since the
avatar and last_seen decisions are independent and all four combinations occur.
Anyone computing MAU from this column should know it was unreliable for every
backfill run before this change.
Also corrects docs/HORIZONTAL_SCALING.md, which claimed oci_client and
registry_domain were local-only preferences. They are fields on
io.atcr.sailor.profile: settings writes them to the user's PDS and
ProcessSailorProfile refreshes the local cache. users is fully derived apart
from last_seen.

Completes the swap 0033 set up. layers and manifest_references move onto
manifest_key and manifests.id is gone, which removes the last node-allocated
identifier in the AppView schema.
Statement order in 0034 is load-bearing. With foreign keys on, DROP TABLE
performs an implicit DELETE FROM, so dropping manifests while layers still holds
an ON DELETE CASCADE reference deletes every layer row. Migration 0009 did
exactly that; it went unnoticed because the Jetstream backfill rebuilds layers
from PDS records, so the damage healed itself. PRAGMA foreign_keys is no help:
it is a no-op inside a transaction and migrations run in one. So the new
children are built pointing at manifests_new, the old children are dropped
first, and only then is the old manifests table dropped, by which point nothing
references it. Verified both behaviors before relying on them.
manifest_key is declared NOT NULL as well as PRIMARY KEY, because in SQLite a
PRIMARY KEY column still accepts NULL unless it is INTEGER PRIMARY KEY. That
constraint immediately caught four test helpers inserting manifests without one.
Five queries used MAX(id) as "the newest manifest in this repo", which I had
previously reported as absent after grepping only for ORDER BY. A derived key
has no ordering, so recency now comes from created_at with manifest_key as a
deterministic tiebreak. This is a real behavior change, and a fix: the two
disagree whenever a manifest is indexed out of order, which the backfill does
routinely, and created_at is the push time these queries always wanted. Both
directions are tested, including that ties resolve the same way every run.
InsertManifest and BatchInsertManifests no longer read anything back. The key is
derived from (did, repository, digest), so the writer knows it before the
statement runs: the select-back, its per-DID IN list, and the "manifest missing
id after batch insert" branch all go away, along with the UNIQUE-conflict
fallback that existed only to recover a rowid.

First half of replacing manifests.id with a node-independent identity. Nothing
depends on the column yet: id is still the primary key, and layers and
manifest_references still reference it. Getting the column in place and filled
first means the eventual swap operates on data that is already complete and
already proven unique, instead of doing the fill and three table rebuilds in one
step.
The value cannot be computed by the migration. It is a truncated sha256, SQLite
has no hash builtin, and go-libsql exposes no way to register one. So the fill
uses machinery that already exists: the Jetstream backfill re-upserts every
manifest across the protocol on startup, and both upsert paths now write
manifest_key.
That only works because of one extra clause. Both upserts guard their DO UPDATE
with a WHERE that skips rows where nothing changed, which on a backfill re-run is
nearly every row, so they would have skipped the very manifests that need
filling. Adding "OR manifests.manifest_key IS NULL" is what makes an otherwise
no-op pass populate the column. Verified by removing it: the backfill then fills
zero of three manifests instead of three of three.
The index is UNIQUE even though the column is nullable. SQLite treats NULLs as
distinct, so unfilled rows coexist while every filled row is checked. That makes
production data verify the 16-byte truncation rather than us assuming it: if two
manifests ever derived the same key, it fails loudly at insert instead of
silently attaching one manifest's layers to another after the swap.
AppView logs the unfilled count at startup, since there is no single moment at
which this becomes complete and the follow-up migration is only safe at zero.
ManifestKey replaces the old fat "did|repo|digest" map key rather than sitting
beside it; they were always the same question, answered without asking the
database.
The jetstream tests hand-maintained their own CREATE TABLE statements, which is
the drift problem moved into a test: the copy had already fallen behind (it still
had tags.id) and only failed once a query touched the difference. They use
db.InitDB now, with foreign keys switched off to preserve the behavior the
hand-rolled schema had.

- diff view gains a Packages tab with added/removed/changed/unchanged
package tables and purl-derived type/license/upstream links
- captain records verified against the DID's atcr_hold service before
caching (processor + batch backfill), preventing forged holds
- fix empty-handle updates clobbering cached handles and colliding on
the UNIQUE constraint
- move fillPrevCIDs into repo.go; DirectRepoOperator is now canonical,
repomgr kept as a test oracle
- surface read-only crew status in hold selector
- reconcile docs
1. Multiple registry domains + per-user domain preference
The biggest feature. The appview can serve several registry domains (e.g. buoy.cr, atcr.io),
and users can now pick which one shows up in their pull/push commands.
- Lexicon/record: adds registryDomain (and documents ociClient)
to the sailor profile (lexicons/.../profile.json, pkg/atproto/lexicon.go).
- DB: new registry_domain column on users (schema.sql + migration 0027),
with GetUserByDID/Handle reads, UpdateUserRegistryDomain writer,
and Jetstream caching it on profile updates (writes unconditionally so clearing propagates).
- UI/handlers: new UpdateRegistryDomainHandler + /api/profile/registry-domain route,
a <select> in the user settings panel (only shown when >1 domain configured), and resolveRegistryURL()
which falls back to the primary domain if the user's pref is stale/removed. Tests added for all of it.
2. default_hold_did removed → first managed_holds entry is the default
Consolidates two overlapping config fields into one. ServerConfig.DefaultHoldDID is gone;
PrimaryHoldDID() now returns managed_holds[0]. managed_holds is now REQUIRED.
Updated in config, validation, server wiring, test harness, example YAML, and the deploy template.
3. Admin long-running operations → generic background-job framework
New pkg/hold/admin/jobs.go introduces a reusable startJob/jobRegistry pattern
(a detached context.Background() job + a /admin/api/jobs/{key}/status polling endpoint).
This replaces the bespoke scan-backfill goroutine state machine, and now also wraps crew tier remap and crew import
all three previously looped synchronously on the request context and got 504'd/cancelled mid-run by the reverse proxy.
Forms switched from POST-redirect to htmx fragments (job_progress.html, job_result.html, crew_import_results.html)
the old crew_import_results.html page and scan_backfill_progress.html partial were deleted.
This is also captured as a new rule in CLAUDE.md.
4. Cascade-delete manifest on last-tag deletion
DeleteTagHandler now, after removing the last tag pointing to a digest, cascade-deletes the manifest itself
(PDS + DB + hold blob purge) — but only if it's not a child of a manifest list (multi-arch parent).
New GetTagDigest and ShouldCascadeDeleteManifest queries back it, plus cascade_delete_test.go.
Also switches tag rkey computation to the atproto.RepositoryTagToRKey helper.
5. Billing simplification
Drops the OwnerBadge config option (hold-owner supporter badge).
The user-profile template no longer special-cases an "owner" badge value (only "Captain").
Example tiers renamed to the nautical scheme (deckhand/bosun/quartermaster).
6. Build/deploy: go generate always runs via Make
make generate is now a phony target that always runs go generate ./... (regenerating cbor_gen, icon sprites, etc.),
and build-trixie depends on it. The deploy tooling (provision.go/update.go)
drops its own runGenerate calls since the Makefile handles it.
7. New cmd/firehose-tap tool (untracked)
A standalone CLI that subscribes to a com.atproto.sync.subscribeRepos endpoint and pretty-prints events,
with emphasis on Sync 1.1 compliance fields (per-op prev CIDs, commit prevData) and a --validate CI mode.
Fits with the recent "more sync1.1 compliant" commit.
did:plc Identity Support (pkg/hold/pds/did.go, pkg/hold/config.go, pkg/hold/server.go)
The big feature — holds can now use did:plc identities instead of only did:web. This adds:
- LoadOrCreateDID() — resolves hold DID by priority: config DID > did.txt on disk > create new
- CreatePLCIdentity() — builds a genesis operation, signs with rotation key, submits to PLC directory
- EnsurePLCCurrent() — on boot, compares local signing key + URL against PLC directory and auto-updates if they've drifted (requires rotation key)
- New config fields: did_method (web/plc), did, plc_directory_url, rotation_key_path
- GenerateDIDDocument() now uses the stored DID instead of always deriving did:web from URL
- NewHoldServer wired up to call LoadOrCreateDID instead of GenerateDIDFromURL
CAR Export/Import (pkg/hold/pds/export.go, pkg/hold/pds/import.go, cmd/hold/repo.go)
New CLI subcommands for repo backup/restore:
- atcr-hold repo export — streams the hold's repo as a CAR file to stdout
- atcr-hold repo import <file>... — reads CAR files, upserts all records in a single atomic commit. Uses a bulkImportRecords method that opens a delta session, checks each record for
create vs update, commits once, and fires repo events.
- openHoldPDS() helper to spin up a HoldPDS from config for offline CLI operations
Admin UI Fixes (pkg/hold/admin/)
- Logout changed from GET to POST — nav template now uses a <form method=POST> instead of an <a> link (prevents CSRF on logout)
- Removed return_to parameter from login flow — simplified redirect logic, auth middleware now redirects to /admin/auth/login without query params
Config/Deploy
- config-hold.example.yaml and deploy/upcloud/configs/hold.yaml.tmpl updated with the four new did:plc config fields
- go.mod / go.sum — added github.com/did-method-plc/go-didplc dependency
