Hold discovery in the registry middleware called getRecord on the
repository owner's PDS for every request under /v2/: every HEAD, POST,
PATCH, PUT and GET. A 10-layer push was 40 or more PDS round trips, and
it was the last per-request network call on the push path that had
nothing to do with moving bytes. Only two profile fields are used
there: the default hold and the auto-remove-untagged flag.
The users row already caches the default hold, written by the Jetstream
processor on every profile event and prefilled by the backfill, and the
auth gate already reads it from there. This makes the row a faithful
copy of what the registry needs and switches the middleware to it.
The auto-remove flag gets a nullable users column. NULL means the value
has never been learned; the processor writes 0 or 1 on every profile
event and never NULL. On a request whose row is missing or still NULL,
the middleware does one live fetch, uses it, and writes both fields
back, including a 0 for a user with no profile at all, so the fallback
runs at most once per user. A failed fetch writes nothing and uses the
appview default for that request, so a network error is never cached.
That single mechanism covers the minutes after a deploy while the
startup backfill fills the column, a brand-new user, and a user the
backfill has not reached.
The processor also stops returning early on an empty default hold,
which left a user who removed their custom hold pushing to it forever.
Empty is now written through and means the appview default, matching
what the auth gate already reads.
Tests count PDS requests with a test server: a populated row makes
none, a NULL row makes exactly one and then none, a missing profile is
cached as known, and a failed fetch degrades without writing. The
migration was applied to a fresh database and to one built from the
previous schema.

Each in-flight blob upload buffers up to 16MB, Docker pushes five layers
at once per client, and nothing bounded the total. Writers also lived in
the package-level map forever: a client that died mid-push left its
writer, its buffer, and any hold-side S3 multipart session behind with
no expiry.
A process-wide budget (golang.org/x/sync semaphore, default 512MB,
server.upload_buffer_budget_mb) now caps memory held in upload buffers.
A writer charges its buffer's projected backing capacity before growing,
so a config blob costs kilobytes and a full writer costs exactly one
buffer, and releases once, on Commit, Cancel, or reap. A write that
needs budget waits on the request's context with a five minute cap,
outside the writer's lock so Cancel and the sweeper cannot queue behind
it; that wait is backpressure on the client. The budget is clamped to
at least one buffer so a single upload can never deadlock.
A sweeper started with the other appview workers reaps writers idle
past server.upload_idle_timeout (default 1h), aborting the hold-side
multipart on a detached context and releasing the budget. It measures
inactivity, not age, so a slow push is never reaped, and it skips a
writer whose lock is held so it cannot race a live part upload.
Write also gains a fix the budget made visible. It appended a whole
chunk and checked afterwards, so the last chunk before a flush could
land a few bytes past 16MB, which did not fit the backing array;
bytes.Buffer doubled it to 32MB and Reset kept that for the rest of the
upload. Only chunk sizes that tile 16MB exactly avoided it, and the
network read loop promises no such thing. Every large layer could hold
32MB while the budget charged 16. Write now fills to exactly the
threshold, flushes, and continues with the remainder, so capacity is
pinned at 16MB for any chunk size, every part is exactly one buffer,
and a single oversized Write streams through as parts instead of
buffering whole. The test streams 24KB chunks across the boundary and
fails against the old code with cap 33554432.

The admin crew tab renders one row per crew member and gives each row its own
hx-get, so opening it on a hold with 551 crew issues 551 requests. Over
HTTP/1.1 a browser runs at most ~6 per origin, so they queue six at a time and
every other request to the same host queues behind them — which is why loading
the relay page stalls while the crew rows are still resolving, and why the rows
that lose the race come back as "Server error" toasts. The 504 behind that toast
is the load balancer's, not the hold's: the hold logs those requests as 200.
HTTP/2 multiplexes them over one connection and the queue disappears. It does
not make the slow rows fast — that is a separate fix to the per-row identity
lookup — but it stops one slow surface from blocking the rest of the panel.
Two halves, because neither works alone.
The load balancer terminates TLS and speaks cleartext to the origin, so ALPN
never runs on the backend leg and net/http can only answer HTTP/1.1 there. Both
servers now wrap their handler in h2c. The wrapper is opt-in per connection: it
upgrades only for a client sending the h2c preface or "Upgrade: h2c", and passes
everything else through untouched, so an HTTP/1.1 WebSocket upgrade is
unaffected. Verified both directions against this wiring — HTTP/1.1 for a plain
client, HTTP/2.0 with --http2-prior-knowledge.
The frontend's http2_enabled was never set, so it sat at the UpCloud default of
off. That is the half the browser actually sees. timeout_client is now stated
explicitly at its current 10s rather than left implicit: it is the boundary that
produces the 504s above, so it belongs somewhere visible. It is deliberately
unchanged — raising it without fixing the slow lookup would only make a stalled
row stall longer.
The hold's *backend* stays on HTTP/1.1. It serves subscribeRepos over WebSocket
to external relays and to the scanner, and WebSocket over HTTP/2 needs the RFC
8441 Extended CONNECT that Go's http2 server does not implement for Upgrade:.
Routing that backend over h2 would break the firehose. The appview accepts no
inbound WebSocket and has no such constraint. Both origins carry h2c regardless,
so enabling it for the hold later is a config change, not a code change.
createLoadBalancer only runs when there is no LB yet, so properties set there
would reach a new deployment and never an existing one. ensureLBHTTP2 reconciles
them onto an LB that already exists, following ensureLBForwardedHeaders: read
what is there, change only what differs, report what it did, and no-op on a
second run. Backend modifies carry the existing health check back, since
Properties replaces the object wholesale.
Also gofmt: provision.go was not gofmt-clean at HEAD, unrelated to this change.

Deleting a tag while over quota could leave the user in the worst available
state. DeleteTagHandler deleted the tag and manifest rows first, then called
PurgeOnHold, which bounded itself at 10s against the *request* context. The
UpCloud load balancer in front of the appview cuts at its default backend
timeout at about the same moment, wins the race, hands the client a 504 and
cancels that context, killing the purge partway. The appview logged a warning
and returned 200.
So: gateway error, nothing freed, still locked out, the image gone from the UI
so the purge cannot be retried through it, blobs orphaned until the hold's GC,
and the appview considering it a success. Measured on production at
10.002367218s.
Purges now go to a fixed pool of 4 workers rooted at context.Background(), so
they survive the request ending. Following the shape of the hold's startJob
helper, minus the progress fragment, since nobody is watching a purge.
The buffer is bounded at 256 and sheds with an ERROR rather than growing: an
unbounded queue turns a slow hold into an appview memory leak. Submissions are
deduplicated on holdDID|manifestURI so a double-clicked delete does one purge
and one service-token fetch. The channel send happens under the mutex that
guards close, so a concurrent drain cannot send on a closed channel, and the
drain is wired into both exit paths before logging shuts down.
Failures are now classified and surfaced instead of swallowed: transient ones
retry three times under a 90s budget (the hold's purge is idempotent), an
unauthorized third-party hold logs at DEBUG since it is expected, and anything
else that exhausts its retries logs at ERROR naming the manifest and hold, which
is enough to re-drive by hand.
Deliberately not reordered. Purge-first-then-delete requires waiting for the
purge to know whether to delete, which puts the 10s call straight back on the
request. So the orphaned-blob window remains, materially narrower but real: a
purge that exhausts its retries still leaves blobs referenced by nothing until
the hold's GC, and there is no row left to say so. Closing that needs a durable
pending-purge record, which was judged out of proportion here.
server.go in this commit also carries one line belonging to the next one, the
token handler's display-name wiring, since the two changes landed in the same
file concurrently.

seamark.dev's /install and /settings/devices told users to pipe
seamark.dev/static/install.sh into bash. That file was the unmodified ATCR
script: it announced itself as the "ATCR Credential Helper Installer",
installed docker-credential-atcr, and finished by telling the user to configure
credHelpers for atcr.io, the wrong registry for that deployment. Anyone
following the documented setup ended up pointed at another service. The
templates hardcoded docker-credential-atcr, "atcr" and ~/.atcr/device.json
alongside a correctly themed {{ .RegistryURL }}.
The scripts are now rendered from config by a handler, rather than forked per
brand. A theme overlay was the alternative and was worse: it needed a full copy
of both install.sh and install.ps1 per brand, four scripts to keep in sync, and
the operator asked for these values to come from config.
credential_helper.name is the single knob. Docker resolves a credHelpers value
x by exec'ing docker-credential-x, so the credHelpers value, the binary suffix
and the config directory are genuinely one word, not three that can drift. It
is validated against a strict pattern because it is interpolated into a shell
script.
install.sh renders byte-identical to the deleted static file under the atcr
default, so existing installs are unaffected. install.ps1 differs by one line,
where a stale usage comment named a path the script is not served at.
Two behaviour changes worth noting: these two URLs drop from a one-year
Cache-Control to five minutes, since the body now depends on deployment config;
and credential_helper.tangled_repo becomes a real overridable default. It was
previously assigned over unconditionally and read by nothing, while the shipped
script used a different URL form.

An unauthenticated token request for a repo on a private hold came back with a
signed token granting pull, and /v2/ then 401ed that exact token. The
authorization server and the resource server disagreed about the same request.
The old behaviour was deliberate — "minting a pull-only token is not a grant",
with the hold owning the decision via captain.Public — but a token spec expects
the server to issue the subset it will authorize, so granting pull and then
refusing it is the wrong shape.
Adds an optional AnonymousAuthorizer, kept separate from Authorizer because the
anonymous path has no DID and no auth method (three of Authorize's four
arguments are meaningless) and because it must drop whole entries rather than
narrow actions in place, where entries can belong to different owners. Denied
entries are dropped; if nothing granting survives, the caller gets the standard
401 challenge rather than a token with an empty access list, so docker prompts
for credentials instead of proceeding to a second 401.
The scope-less /v2/ ping and the actionless entry NarrowToPullOnly preserves on
purpose both bypass the gate entirely — no identity resolution, no hold lookup —
since anonymous discovery depends on them.
Fails open on any lookup error, matching the /v2/ check, which states the
reason: the hold is the enforcing authority and a transient failure must not
break anonymous pulls of public images. /v2/ still enforces; this is a
correctness and UX fix, not a security fix, and nothing was exposed.
Also closes the successor asymmetry documented under finding 3: /v2/ applies a
single-hop migration redirect before checking read access, so judging the
pre-migration identity here would have reintroduced the disagreement this gate
removes. It was one extra local read of hold_captain_records. Tests pin both
directions and prove the chain is not followed past one hop.
Costs one directory-cached identity resolution plus two local SQL reads per
granting entry, and no call to the hold.

/v2/_catalog answered a bare request with 200 {"repositories":[]} but 400ed
any n, because buildDistributionConfig leaves Catalog.MaxEntries at 0 and the
library rejects n > max. crane catalog sends n=1000, so it always failed. The
same endpoint both worked and rejected a legal parameter.
Setting MaxEntries was the obvious fix and is the wrong one. This registry has
no global catalog and will not grow one: repositories live in per-user ATProto
PDS namespaces, and buildStorageConfig hands the library a placeholder
inmemory driver, so its enumeration is empty by construction. An empty 200
asserts that this registry contains no repositories, which is false and
silently so. UNSUPPORTED says the true thing, and matches the vocabulary
DomainRoutingMiddleware already uses to refuse /v2/* on the UI domain.
There is no conformance cost: _catalog is not in the OCI distribution spec at
all. It is a Docker Registry HTTP API V2 extension, and the spec places
repository discovery out of scope. Docker Hub and GHCR both refuse it outright
and Quay returns an unconditional empty list; none of them 400s a legal n.
The path had three distinct behaviours, not two, and all three now collapse to
one: GET varied by parameter, HEAD was answered by gorilla's MethodHandler
with a bare 405, and the trailing-slash form 301-redirected because
distribution sets StrictSlash(true). Both path forms are registered, and chi
prefers a static pattern over the /v2/* wildcard regardless of declaration
order (verified against the pinned chi version, and pinned by a test that
fails if a request reaches the distribution stand-in).
Also adds the Allow header that RFC 9110 requires on any 405 — a MUST in both
15.5.6 and 10.2.1, not a SHOULD. The value is empty, which 10.2.1 defines as
"the resource allows no methods": true for the catalog, and true for /v2/* on
the UI domain, so the pre-existing gap in DomainRoutingMiddleware is closed
too. Naming a method there would advertise something that does not work.

Go's net/http compresses nothing by default and the appview is served by a
raw Go server behind a load balancer that does not compress either, so
everything went out uncompressed: style.css at 180 KB, bundle.min.js at
105 KB, and the homepage HTML at 95 KB. Lighthouse put style.css alone at
1,768 ms of blocked first paint, and mobile Performance measured 77 against
98 on desktop, entirely on paint metrics (TBT 10ms, CLS 0).
klauspost/compress is already a direct dependency and ships gzhttp, so this
costs no new one. Brotli would save roughly 11 KB more across the three
largest assets in exchange for a runtime dependency, which is not worth it.
The /v2 skip is the part that needs care. The OCI registry API is mounted on
the same chi router as the UI (server.go:561), and container layers are
already gzipped tarballs, so compressing that path burns CPU for no gain.
The content-type allowlist would catch most of it, but /v2/* also serves
application/json for tag listings and errors, so the path check keeps the
registry out of the compression path entirely. The predicate matches the one
the domain-routing middleware already uses.
Measured against a local build, gzip vs identity:
/ 14,526 -> 4,298 71%
/css/style.css 183,990 -> 31,596 83%
/js/bundle.min.js 107,781 -> 32,648 70%
/icons.svg 26,360 -> 8,403 69%
total 332,657 -> 76,945 77%
Verified end to end against a running binary: UI and static responses carry
Content-Encoding: gzip with Vary: Accept-Encoding, /v2/ and /v2/*/tags/list
carry neither, and woff2 stays untouched. Tests cover both directions plus
the under-1 KB and no-Accept-Encoding cases.
HTTP/2 is the remaining half and cannot be fixed here: the load balancer
terminates TLS and negotiates no ALPN at all, which pins every request to
HTTP/1.1. That is an LB setting.

6a7ddb8 moved RefreshHoldTiers under a lease with the comment "one-shot; the
lease is released when it returns". It never returns: past the startup retries
it sits on a 30-minute ticker forever. Three consequences, all observed on a
two-instance run against one database:
The billing-tiers lease is never released on a clean stop, so it survives to
its TTL and the replacement instance waits a full minute for a worker the old
one is no longer running. Worse, the goroutine stays in the shutdown WaitGroup,
so "Timed out waiting for leased workers to stop" now fires on EVERY clean
shutdown. The other four leases released in 12ms and the warning fired anyway.
A warning that is always present cannot report the case it exists for, which is
the jetstream lease genuinely failing to release.
And the lease was the wrong tool regardless. The commit justified it as
"RefreshHoldTiers writes tier state derived from Stripe" that instances would
race on. It writes holdTierCache, a per-process map, from read-only ListTiers
calls; there is no shared state anywhere in the path. Electing one refresher
means every other instance keeps an empty cache forever, so
aggregateHoldFeatures reports "no hold data" on all but one — a regression that
only appears at the scale the lease was added to support. This is the hold
health worker's situation exactly, and that one was deliberately left unleased
in the same commit.
So it runs on every instance again, with a context. The retry backoff was
time.Sleep for up to 45s total against an unreachable hold; it and the ticker
now select on ctx.Done, and ListTiers gets the context instead of
context.Background. LeaseBillingTiers is gone rather than left as a dead name.
Verified: with the backoff restored to time.Sleep the new test fails on its own
2s deadline rather than hanging, which is how a shutdown regression here should
present.

The link was hardcoded before fa34da0 too — it pointed at
bsky.app/profile/atcr.io. That commit was right to switch to a DID, since
handles change and a stale handle link breaks silently, but the DID went into
components/footer.html, a shared template. Every self-hoster's footer therefore
links to the project's Bluesky account.
Now ui.bluesky_profile, following source_url in the same footer exactly:
config field with a default, plumbed through UIDependencies and PageData, and
guarded with {{ with }} so an unset value omits the link rather than rendering
something wrong. It takes a handle or a DID; the comment says to prefer a DID
for the reason fa34da0 changed it.
Defaulting to the project account matches source_url's logic — both name the
upstream project rather than the operator — and self-hosters who want their own
or none set one line.
The aria-label switched to $.ClientShortName: `with` rebinds the dot, so the
label would otherwise have silently rendered empty.
Two things worth recording:
* `{{ with }}` hides the link on an empty value, but you cannot get an empty
value from the environment. Viper runs with AllowEmptyEnv(false), so an
empty env var reads as unset and the default wins. Only "" in YAML works.
That applies to every string field in this config, not just this one, and
the comment now says so.
* config-appview.example.yaml must NOT be regenerated with `config init`,
despite what the checklist in CLAUDE.md says. The file is hand-curated well
past the defaults, and regenerating replaces real Stripe price IDs with
price_xxx placeholders and blanks registry_domains, managed_holds, theme
and the tier names. Added by hand instead.
Verified live both ways: the configured value renders, and `bluesky_profile: ""`
in YAML drops the link while leaving the Source link intact.

DomainRoutingMiddleware normalized the request Host to a bare hostname but
matched server.registry_domains verbatim, so any configured domain carrying a
port could never match. config-appview.example.yaml ships
`registry_domains: [127.0.0.1:5000, atcr.io]`, which means that entry has been
inert since it was written.
It fails closed in the worst way. That same host is also the auto-detected UI
host, and `host == uiHost` was evaluated first, so /v2/* was answered with
"registry API is not available on this domain, use 127.0.0.1:5000" — naming the
exact host the client had just used. The registry API is unreachable on the dev
stack, and any single-host deployment hits the same wall: listing a host in
registry_domains does nothing if it is also the UI host.
Both sides are now normalized through hostWithoutPort, and a registry domain
takes /v2/* even when it doubles as the UI host, which is a legitimate
single-domain deployment. Everything else is unchanged: a UI-only host still
refuses /v2/, registry domains still redirect non-/v2 traffic to the UI, and
/auth/token and /auth/device/* are still served directly so a cross-host 307
cannot strip the Authorization header.
hostWithoutPort uses net.SplitHostPort instead of the previous LastIndex(":")
scan, which mangled bracketed IPv6 literals into "[::1" and could never match
the "::1" that url.URL.Hostname() yields for the UI host.
The middleware had no tests at all. The two failing cases are pinned first, and
the four pre-existing behaviours are pinned alongside them so the reorder
cannot quietly widen what /v2/ is served on.
Pre-existing at efabb677 rather than introduced by this range, but it blocks
every registry-facing batch in the stack, so it lands at the base.

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.

ClearAllDenials ran unconditionally at startup, and its database half is
"DELETE FROM hold_crew_denials" with no scoping at all. One instance, that is a
clean slate on deploy. Several instances, and a rolling deploy wipes the shared
table once per instance while every scale-out event wipes it again, so the
backoff that exists to stop a denied client hammering a hold's PDS keeps getting
reset out from under it.
The intent is worth keeping: a restart usually means a fix shipped, and someone
sitting on a backoff of up to an hour should get to retry rather than wait it
out. So it moves under the cleanup lease instead of being deleted, and now
happens once per deploy rather than once per instance.
Worth noting the in-memory half was always a no-op here. recentDenials belongs
to the process, and a process that has just started has an empty one, so the
table-wide DELETE was the only thing the startup call ever really did.
The cleanup worker moved down past the hold authorizer's construction, since it
now needs a handle on it. Reading s.HoldAuthorizer from the worker goroutine
while the constructor was still assigning it would have been a data race.

The Jetstream consumer, backfill, labeler subscriber, cleanup sweep and billing
tier refresh all started unconditionally in every process. That is correct for
one instance and wrong for two.
The consumer is the case with teeth. StatsCache is per-process in-memory state,
and the aggregate it produces is written to repository_stats as an absolute
value rather than an increment, so two consumers each hold a partial view of the
holds and each write their partial sum as though it were the whole truth,
overwriting one another indefinitely. The webhook dispatcher hangs off the same
processor, so a second consumer also doubles every delivery.
Each now runs under a named lease, so exactly one instance runs it and a
replacement takes over when that instance goes away. The health worker is
deliberately not leased: it refreshes a cache each instance needs locally, so
running it everywhere is correct.
Two structural changes came with it. The cleanup loop moved out of
InitializeDatabase, where it was a bare goroutine with no way to reach the lease
manager, into RunPeriodicCleanup called from the server. And backfill's startup
run and periodic schedule became one leased worker instead of two goroutines on
context.Background(), so shutdown actually stops a backfill in flight rather
than letting it run on against a closing database. With interval=0 that worker
holds its lease instead of returning, since releasing would let another instance
acquire and run its own startup backfill, turning "once" into "once per
instance".
Verified with two instances against one database: exactly one acquired, the
other contended without starting a worker; SIGTERM handed over in 13ms via the
release, SIGKILL handed over in ~12s via TTL expiry.
That first number only holds because of Manager.Go and Manager.Wait, which this
commit adds. The first cut used `go m.Run(...)` and cancelled the worker context
during shutdown without waiting, so the process exited before the release landed
and the lease survived to its TTL — a rolling deploy would have paused indexing
for a minute rather than a second. Nothing in the unit tests caught it; the
two-instance run did. TestWaitBlocksUntilLeaseReleased covers it now.
leases.enabled defaults to true. A single instance is unaffected, since it
always wins its own leases, while an operator who scales out without reading the
docs still gets correct behavior instead of silent stats corruption.

a7569a7 added credential-less pulls of public images. Three things about it
were wrong, all of them in how the appview handled the decision that belongs
to the hold.
**Scope handling was all-or-nothing.** IsPullOnlyScope required every
requested action to already be "pull", but clients routinely ask for more
than the operation needs — pull,push is common for a plain read, and some
ask for pull,push,delete up front. Those were rejected and challenged,
leaving a credential-less client no way to pull even a public image, which
is the entire feature. NarrowToPullOnly drops the write actions and issues a
token carrying "pull" and nothing else. Granting a subset is what the
distribution token spec expects. The allowlist property is preserved: "pull"
is the only action that survives, and "*" is deliberately not expanded into
it, since a wildcard request is not evidence the caller wants a read.
**The appview-side read gate was inert.** checkReadAccess passed p.ctx.DID,
the DID of the repository *owner*, not the requester. Any non-empty DID
satisfies a private hold's check, and the owner's is never empty, so it asked
"may the owner read their own hold", answered yes, and admitted everyone.
Worse, CheckReadAccessWithCaptain admitted any authenticated DID to a private
hold at all, on an explicitly-MVP assumption that holding a DID was close
enough to being a sailor. Every doc says otherwise (docs/hold.md:109 "Crew
with blob:read", CLAUDE.md:140, docs/BYOS.md:280) and so does the hold
(ValidateBlobReadAccess: owner, or crew carrying blob:read/blob:write). It
now takes isCrew and requires owner-or-crew, and callers only pay for the
crew lookup when it can change the answer — a public hold or an anonymous
caller is decided by the captain record alone. Nothing here loosens access;
it brings the local gate into agreement with the authority.
**Denials could not reach the client.** distribution's blobHandler.GetBlob
maps everything except ErrBlobUnknown to ErrorCodeUnknown, so a 401 raised
in the blob store left as a 500 — misreporting an auth failure as a server
fault, and giving BearerChallenge no 401 to attach WWW-Authenticate to, so
Docker was told "server error" instead of being prompted for credentials.
Clients that retry 5xx looped: 4.1s per case in the matrix, now 0.01s. The
check moves to Repository(), where an errcode.Error is passed through
verbatim by the registry app — the same mechanism a7569a7 used for
NAME_UNKNOWN. It fails open on a lookup error, since the hold is the
authority and a transient failure should not break public pulls.
Removes auth.allow_anonymous_pull. It could only ever withhold — captain.Public
is what grants — so it was a second flag for a decision the hold already owns,
and gating it appview-side was never the intent. Layer bytes 307 straight to
S3, so the appview is not even in the path whose cost might have justified an
operator-side lever.
Tests: TestAuthMatrix only ever ran against a public hold, and its pull cases
never fetched a layer — crane.Pull is lazy and img.Digest() needs only the
manifest, which ATCR serves from the user's PDS where it is world-readable, so
no pull row in the matrix touched blob authorization at all. Pulls now
materialize layer bytes, and testharness.WithPrivateHold plus
TestAuthMatrixPrivateHold cover public:false + allow_all_crew:true — the
production shape, where anyone with an account pulls and pushes and anonymous
gets nothing.

Credential-less pulls of public images. /auth/token issues a pull-only
token with an empty subject when no Basic auth is present; the
destination hold still enforces captain.Public, and push or delete always
challenges.
- token.IsPullOnlyScope and AuthMethodAnonymous;
Handler.issueAnonymousToken skips the authorizer gate and the
service-auth pre-mint, since there is no identity to reconcile and no
AppView-to-hold service token to bind. The token is still stamped
with the resolved registry domain, so anonymous pull works on
secondary front doors whose access controller demands their own
audience.
- auth.allow_anonymous_pull (default true) turns it fully off, restoring
the previous always-challenge behavior. Mirrored into the deploy
template, since the default means existing deploys pick this up.
- RegistryContext.Anonymous is plumbed from the middleware.
- ProxyBlobStore sends no Authorization header when the service token is
empty, and returns 401 rather than 403 for anonymous denials so Docker
prompts for credentials, including when a stale captain cache lets the
request through and the hold says private.
- BearerChallenge wraps the /v2/ subtree so a 401 raised deep in the
stack via errcode.ServeJSON still carries WWW-Authenticate.
Distribution's own scoped challenges are left alone.
IsPullOnlyScope allowlists the pull action instead of denylisting push and
delete. Distribution's actionSet.contains treats "*" as *every* action, so
a scope of `repository:victim/img:*` names neither denied string and would
have handed an unauthenticated caller a token valid for push and delete on
someone else's repository — clearing the authgate entirely, since anonymous
tokens deliberately skip it. Writes would still have failed further down
(no PDS credential), but the gate itself was bypassable. Now every
requested action must be exactly "pull". Covered by new claims tests.
Unresolvable identities return NAME_UNKNOWN instead of a bare error that
distribution renders as 500. This path was previously unreachable without
credentials; anonymous pull opens it to the internet, and a 5xx on
arbitrary input both misreports a bad request as a server fault and sends
clients that retry 5xx into a retry loop. That loop was real: in the auth
matrix, regclient spent 83s on a single case before this fix, and the
suite now runs in 5s.
Stat preserves an authorization verdict from getPresignedURL rather than
flattening it to ErrBlobUnknown. Distribution calls Stat before ServeBlob
on GET and HEAD, so without this an anonymous pull from a private hold
answered 404 and BearerChallenge had no 401 to annotate — the 401 path
above could never actually reach a client.
The auth matrix is updated to match: anonymous pull of the seeded public
repo now succeeds, anonymous push is denied against a real identity's
namespace (rather than an unresolvable one, which was testing name
resolution rather than authorization), and a new case pins the
NAME_UNKNOWN behavior for an unknown identity.

The webhook limit was only checked at creation, so losing entitlement (a
hold switch or a plan downgrade) left previously-created webhooks firing
paid behavior forever.
- Dispatcher takes a WebhookLimiter, consulted on every dispatch. It
caps the list to the current allowance, keeping the oldest N to match
what the creation gate would have permitted, and masks paid trigger
bits.
- GetWebhooksForUser orders by created_at ASC, id ASC so that cap is
deterministic. ListWebhooks gets the same tiebreak: it feeds the
settings UI, and without it the list a user sees could disagree with
the one the dispatcher truncates.
- webhooks.FreeTriggerMask is shared by the creation gate and the
dispatch backstop so the two cannot drift.
Capping is logged when it actually truncates. The webhooks stay visible in
settings, so from the user's side delivery would otherwise just stop with
no signal — and the same line is the only evidence if the limiter itself
degraded, since a billing lookup failure falls back to free-tier limits
and would quietly demote a paying user mid-dispatch.
Two cost fixes, both because this puts the entitlement lookup on a hot
path it was never on before:
findCustomerByDID now consults the customer cache instead of always
issuing a Stripe customer search. GetWebhookLimits reaches it via
GetSubscriptionInfo on every delivery, so uncached it meant a
rate-limited Search API call for every push and every scan record of
every user with a webhook configured.
DispatchForQuota checks whether the user has any quota webhook at all
before fetching the allowance. The original code filtered first precisely
so the common path (no quota webhooks) did no work; taking the allowance
up front would have spent the expensive lookup on every push. The cap
itself is still computed over the full list, since the count limit spans
all webhook types.
Note DeliverTest is deliberately not capped: it is an explicit,
user-initiated "send test" from the settings page, not automatic delivery.

Entitlements were keyed on the Stripe subscription alone, so a subscriber
who switched to a self-hosted hold kept paying for features the appview
cannot deliver, and could still reach checkout.
- billing.ActiveHoldChecker and Manager.onManagedHold gate every
entitlement. An empty default hold counts as managed: the user has no
explicit preference and falls back to the operator's primary managed
hold.
- The checker reads the primary DB, not the read replica. A hold switch
writes default_hold_did to the primary, and replica lag would keep
paid features alive after a switch away.
- db.GetUserDefaultHoldDID is the clean default-hold signal, unlike
GetUserHoldDID which falls back to a manifest hold_endpoint (a URL,
not a DID).
- Jetstream fails closed: an unresolvable hold reference is cached raw
rather than left empty, since an empty value reads as managed.
- UI: the billing tab is hidden on self-hosted, a cancel/manage banner
appears when a self-hosted user still has an active plan, the image
advisor returns managed_hold_required instead of upgrade_required,
and the checkout route returns 403. The portal stays open so existing
subscribers can still cancel.
Two consistency fixes fall out of wiring this up:
The settings UI reads the resolved default_hold_did rather than the raw
profile.DefaultHold. The profile field is the record value as written and
may be a URL-form reference; jetstream resolves it to a DID on the way
into the DB, and the server-side gate reads that resolved value. Comparing
the raw form against managed DIDs would show the "you are self-hosted"
banner and hide billing from a user whose entitlements say otherwise.
HasAIAdvisor falls back to the free tier's AIAdvisor setting when
off-managed instead of a hard false, matching GetWebhookLimits. Losing a
managed hold should drop a user to free-tier entitlements, not below them.
BEHAVIOR CHANGE for existing paying users on self-hosted holds: they lose
the AI advisor, supporter badge and paid webhook limits as soon as this
deploys, while Stripe keeps charging them. The only notice is the banner
on /settings/storage, which they have to visit to see. Decide on a
migration (notification, or a one-time reconciliation over active
subscriptions) before shipping this.

Webhook delivery was neither idempotent nor order-safe, and every failure
returned 400, which Stripe does not retry. A transient DB or hold error
therefore dropped a subscription change silently and permanently.
- New stripe_processed_events table: event_id as primary key dedups
redelivery, and event_created per customer drops stale out-of-order
deliveries.
- HandleWebhook distinguishes ErrWebhookSignature (400, no retry) from
ErrWebhookProcessing (500, Stripe redelivers). The event handlers
return errors instead of swallowing them. ErrBillingDisabled maps to
400: the route is mounted but billing is off, so redelivery can never
succeed and Stripe should stop rather than retry to exhaustion.
- Refuse to boot when billing is enabled with an empty
STRIPE_WEBHOOK_SECRET. Stripe HMACs with the empty key, so an
attacker can reproduce the signature and the endpoint is forgeable.
- UpdateCrewTierOnAllHolds retries each hold (3 attempts, linear
backoff, 5s per request) and returns a joined error so the webhook
can fail and let Stripe redeliver.
The fan-out contacts holds concurrently rather than in sequence. Serially,
one unreachable hold burns the caller's entire 10s budget on its own
retries (3 x 5s plus backoff) and the holds after it are never contacted;
because Stripe redelivers in the same order, a persistently-down first
hold means the rest are never updated at all.
On the hold, the signature-validated sub claim is now the source of truth
for updateCrewTier: a mismatched body userDid is rejected with 403 rather
than retargeting the grant to another DID. "Not crew on this hold" is a
200 no-op, since the appview fans updates out to every managed hold and a
subscriber is not crew everywhere.
That no-op has to be told apart from a storage failure. GetCrewMember
collapsed both into one generic error, so a CAR-store failure read as
"not a member", answered 200, and let the appview record the event as
processed — losing the tier grant permanently, which is exactly the
failure mode this commit exists to prevent. Missing records now carry an
ErrCrewMemberNotFound sentinel, and anything else returns 500 so Stripe
redelivers.

The route was registered GET-only, so containerd and Docker, which try the
OAuth2 POST endpoint first whenever they hold a secret, ate a 405 and retried
on the GET form. Every authenticated pull paid two auth round trips, and in the
production logs the POST share of token traffic grew from 0.5% to 38% over six
weeks as more clients pulled from k8s with basic-auth imagePullSecrets.
Serve both specs on the same path. After credentials and scope are extracted
the two paths are identical, so this is an extraction branch plus a form-shaped
error writer.
Only grant_type=password is supported and no refresh token is issued: the
registry JWT's lifetime is pinned to the AppView<->hold service-auth, so a
refresh token would be a fourth long-lived credential with its own storage and
revocation. Clients handle its absence by continuing to use the credential they
already hold.
The refresh grant is refused with 401 rather than the 400 that RFC 6749 5.2
prescribes. containerd sends that grant only when it has no username, which is
the same condition that disables its 405 fallback, so a 400 would hard-fail
those clients. 401 is on its retry list and routes them to the GET form, where
a device secret authenticates off the password alone. That shape previously had
no working path at all.
resolveService now takes the requested service as an argument, since it arrives
in the query string on GET and in the form body on POST.

An AppView can front several registry domains that all reach the same
backend (seamark.dev serving buoy.cr, seamark.cr, and soon atcr.io).
Distribution's token access controller holds `service` as a single string
and uses it twice: as the value advertised in the WWW-Authenticate
challenge, and as the sole accepted JWT audience. So it announced one
domain's name on every domain, and honoured one domain's tokens
everywhere. A push to seamark.cr was challenged with service="buoy.cr".
Both uses sit inside Authorized, which already has the request, but the
value is fixed at construction and reachable through no hook — autoredirect
only templates the realm. So register an "atcr-token" controller that
builds one upstream controller per domain and dispatches on r.Host. Each
front door now advertises its own name and demands its own audience. All
signature, certificate and claim verification stays in upstream code; this
only routes.
The token handler stops discarding ?service= and stamps the audience with
the front door the client used, allowlist-checked against the configured
domains so the value stays server-determined despite arriving from the
client. It has to come from the query param because the realm lives on the
UI host, where r.Host names no registry domain.
This is token hygiene and spec conformance, not a privilege boundary: every
domain fronts the same backend, so a client can obtain a token for any of
them just by handshaking there. What it buys is a truthful challenge and
the decoupling needed to later split a domain onto its own AppView.
Also unify the domain list. DomainRoutingMiddleware keyed its map on the
raw config while matching a port-stripped host, so a domain configured with
a port could never match its own requests. It now shares the normalized
cfg.Auth.Services, so routing and authorization agree on one set of names.
cfg.Auth.ServiceName was an exact alias for Services[0] and is replaced by
PrimaryService(), which also removes an empty-slice index.
Rollout: the audience for seamark.cr and bouy.cr changes, so a token minted
just before the restart draws one 401 and Docker re-handshakes into a valid
one. buoy.cr is unchanged (it stays primary), and atcr.io keeps the service
name it already has today. The challenge and the accepted audience come
from the same delegate, so the retry converges by construction. Deploy as a
single flip, not a canary: an old instance ignores ?service= and would keep
minting the primary audience while a new one rejects it.

- 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.
