Evan JarrettandClaude Fable 5.1 9dbc53b670 appview: stop serving service tokens past their expiry, and challenge the client when the hold rejects one
Seen in production on 2026-09-11: three cold pulls of a 22-layer image failed
with BLOB_UNKNOWN for layers that exist. The hold had answered 403 "service
token authentication failed: token has expired", and the same blobs served
fine a minute later.

Three things lined up. The registry middleware's validation cache kept a
fetched service token for a flat 45 seconds regardless of its real remaining
life, so a token fetched with 12 seconds left was still handed to the hold
half a minute after it died. The registry JWT is stamped from the auth cache's
expiry, which trailed the real exp by only 10 seconds, while distribution
accepts a JWT for 60 seconds past its exp, so a client could hold an accepted
JWT for most of a minute after the credential behind it was gone. And the
hold's 403 was flattened to BLOB_UNKNOWN, so the client failed instead of
re-authenticating.

Now the validation cache bounds an entry by the token's exp minus a shared
ServiceTokenSafetyMargin of 60 seconds, the same margin the auth cache and the
JWT stamp use, chosen to equal distribution's leeway so the last instant a JWT
is accepted is the service token's real exp. A PDS that grants less than the
margin gets half its remaining life instead of an already-past deadline. When
the hold rejects the service token as expired or missing, the appview drops
both cached copies and returns a 401 challenge so Docker and crane re-run the
token dance and retry; a genuine permission denial stays a 403, and a hold
that is down still maps to blob unknown.

Evan JarrettandClaude Opus 4.8 2a94f924af appview: memoize blob presigns within a request
A blob GET cost three hold calls, not two. distribution's blob handler
calls Stat then ServeBlob, and its notifications listener (installed
unconditionally, endpoints or not) calls Stat a third time after ServeBlob
to build the pull event. Each Stat presigned method=HEAD and ServeBlob
presigned the request method, so a p90 pull of 22 layers was 66 hold
getBlob calls, 44 of them HEAD presigns whose URL was discarded.

ProxyBlobStore is built once per request (the sync.Once in
RoutingRepository.Blobs), so a per-instance memo keyed by digest+method is
request-scoped. Stat reads the request method from the context and presigns
for GET or HEAD accordingly (anything else, including the push existence
check and manifest verification, still presigns HEAD, which the hold's read
path requires). ServeBlob and the listener's second Stat then hit the memo.
S3 signs the HTTP verb, so the key includes the method: a HEAD URL cannot
serve a GET. Only successful presigns are cached, so error semantics are
unchanged.

The missing-size fallback (older hold) now probes with a HEAD-signed URL
rather than GETting the blob body when Stat presigned for GET.

Measured with TestBenchRealImages: p90 pull drops from 67 hold calls to 23,
one per blob, and wall time at PDS 50ms / hold 5ms / S3 20ms drops 23%.
Push counts are unchanged.

Evan JarrettandClaude Fable 5.1 bf4e63e810 test: production-shaped push/pull benchmark with per-backend request counts
TestBenchRealImages pushes and pulls three images whose layer sizes are
copied from real manifests in the production appview database (the median,
p75 and p90 images by layer count) and reports, per operation, wall time and
the number of requests to the registry, the fake PDS, the hold and S3, broken
down by endpoint. Skipped unless BENCH_PROFILES is set, so the integration
target does not run it. BENCH_LAT_{PDS,HOLD,S3} inject per-request latency,
which is what makes byte-path changes visible in-process; request counts are
the reliable signal either way.

internal/reqcount counts and delays requests through a handler wrapper and a
client-side RoundTripper. testharness.WithBackendTap wraps the PDS and S3
handlers and puts a counting reverse proxy in front of the hold;
testpds.WithMiddleware is the hook that makes the PDS side possible.

The bench showed a pull costs three hold calls per blob, not two: distribution
installs its notifications listener unconditionally and it re-Stats every blob
after ServeBlob to build the pull event. The backlog's presign memoization
item is rewritten with the measured numbers.

Evan JarrettandClaude Fable 5.1 65db7945b2 appview: drop the testmode fall-back-to-default-hold probe
The registry middleware used to GET the user's hold's /.well-known/did.json
on every registry request in testmode builds, and fall back to the appview
default hold if it did not answer. The fallback only ever changed anything
when the user's chosen hold differed from the default AND was down; in local
development and in the integration harness the two are the same hold, so the
probe's answer was discarded every time. In the production-shaped benchmark
it was 94 of 150 hold requests per p90 push and 23 of 90 per pull, hiding
the real hold traffic behind a testmode artifact.

Remove isHoldReachable, the fallbackUnreachable field, and the probe branch.
An empty choice still means the default hold. Testmode and production now
take the same path here.

Evan JarrettandClaude Fable 5.1 dcee8f6a62 deps: upgrade every module; gate loopback OAuth tests on testmode
go get -u across the root, scanner, and deploy modules, then tidy. The
credential helpers pin atcr.io v0.1.4 for standalone go install and are
left alone (go work sync tried to strip that pin; reverted). Direct
upgrades in the root: indigo 20260901 to 20260903, aws-sdk-go-v2 core
1.45.1 to 1.47.0 with config, credentials, and s3 alongside, x/crypto
0.55 to 0.57, x/net, x/sync, x/sys, x/image, klauspost/compress 1.20,
go-containerregistry 0.22.1, goldmark 1.8.6, regclient 0.11.6 (pinned
only by the integration-tagged package, so the bulk upgrade skipped it).
Scanner and deploy had no direct updates; their indirect sets moved.

The indigo delta is a hardening series: identity.DefaultDirectory and
oauth.NewClientApp now carry an SSRF-guarded transport that refuses
loopback and private ranges, did:web and well-known bodies are size
capped, all auth-server endpoints must be HTTPS URLs, and MST decoding
validates PrefixLen on untrusted nodes. Production is unaffected. The
testmode seam in pkg/atproto absorbs the rest: a probe confirmed an
untagged build now refuses 127.0.0.1 with indigo's unsafe-address error
and a tagged build dials through.

Two OAuth tests drove the real client against httptest servers on
loopback and failed untagged after the bump; three siblings in the same
fixtures passed only because the refused dial happened to satisfy a
"transient error" assertion. All five, with their fixtures and fake
stores, move under //go:build testmode in sibling files.

Evan JarrettandClaude Fable 5.1 0080957a21 remove the runtime test_mode switch; the testmode build tag is the only one
server.test_mode survived the build-tag refactor only to feed five
behavioral branches: the registry's fall-back to the default hold when
the user's hold is unreachable, backfill warning suppression for
external holds, the appview listener close on shutdown, the hold's
relay-crawl skip, and the hold's appview-issuer tolerance. Every one of
them is a "this is a local development build" decision, which is what
the tag already says, and local development has to build with the tag
or nothing resolves. So they read atproto.TestModeBuild now, and the
flag, SetTestMode, IsTestMode, the middleware option, the backfill
constructor parameter, the never-read field on RemoteHoldAuthorizer,
the example and template YAML lines, and the docker-compose env vars
are gone. The registry keeps the fallback as a field seeded from the
constant so the production-path tests can pin it off under the tag.

The 24 SetTestMode calls in tests were dead already: stripping them and
running the affected packages tagged changed nothing.

Tests that resolve a loopback did:web used to t.Fatal naming the tag,
which left a bare `go test ./...` permanently red in five packages.
They now live under `//go:build testmode`: whole-file constraints where
every test needs it, and sibling *_testmode_test.go files holding the
moved tests plus their fixtures where a file mixed. The harness carries
the constraint too, with its package doc in an untagged doc.go so the
package still exists without it. An untagged run compiles those tests
out and passes; make test keeps the tag and runs everything.

Evan JarrettandClaude Fable 5.1 d8643ee03a config: describe what test_mode still controls
The comments on server.test_mode predated the testmode build tag and
still claimed the flag allows HTTP DID resolution (appview) or changes
OAuth redirects (hold). Neither is true: DID resolution is decided at
build time now, and the hold's OAuth redirect never read the flag. Say
what remains behind the runtime switch on each side and point at the
build tag for the rest.

Only the comment lines in the example YAMLs are updated; the examples
carry hand-edited values and are not regenerated.

Evan JarrettandClaude Fable 5.1 a01b08b924 atproto: gate local indigo behavior behind a testmode build tag
indigo's identity directory refuses HTTP and IP-hosted did:web, and its
OAuth client is growing an SSRF-guarded transport that refuses loopback
and private addresses. Local development and the test suites need both,
and the workarounds were scattered: two did:web fallbacks in the
resolver, a hand-rolled appview key fetch on the hold, and the OAuth
client left on indigo's defaults so any test driving it against an
httptest server depended on the transport staying permissive.

Move every departure from indigo's defaults into one file pair in
pkg/atproto: indigo_prod.go (!testmode) returns indigo's directory and
OAuth client unchanged; indigo_local.go (testmode) wraps the directory
so a did:web naming an IP, localhost, or a host with a port resolves
over plain HTTP, and gives the OAuth client plain HTTP clients. All six
identity and OAuth constructor call sites go through NewDirectory and
NewOAuthClientApp. The resolver fallbacks, DIDWebToURL, and the hold's
scheme-guessing key fetch are gone; the hold resolves the appview key
through the directory, preferring #appview, and purges and retries once
on a signature failure so a re-keyed appview is not masked by the
24-hour cache.

There is no runtime switch for this: a production binary cannot be
configured to resolve local DIDs. The runtime test_mode flag still
gates the remaining behavioral branches only.

Tests, the harness, make dev, Air, Dockerfile.dev, and docker-compose
build with the tag; fixtures that need loopback did:web fail fast
naming it. Test hold servers now serve a did.json via pkg/testpds so
they resolve as real holds under the tag.

Evan JarrettandClaude Fable 5.1 7b67b3b383 appview: mark repo cards translate="no"
Repository cards hold user-written handles, names, descriptions and
image references. Browser translators (Chrome, Edge, Safari, and
Firefox once a translation is accepted) honor the translate attribute
on elements below the root, so the card contents stay as written while
the rest of the page translates. This does not suppress the browser's
translate offer, which is a page-level decision driven by language
detection.

Evan JarrettandClaude Fable 5.1 16375ce302 appview: name uploads with a UUID, not the nanosecond clock
ProxyBlobStore.Create named every writer fmt.Sprintf("upload-%d",
time.Now().UnixNano()) and used that as its key in globalUploads. The
nanosecond clock is not a unique source: Go's wall clock is coarser than
the spacing between goroutines, so two uploads opened at the same instant
read the same value. On this box, two goroutines released together
collided about 18% of the time (tsc clocksource).

That is reachable on every multi blob push, because Docker and crane POST
the config blob and several layers concurrently. When it happened the
second writer silently replaced the first in the map, both clients' PATCHes
resumed the same writer, and distribution rejected the second with a 416
"upload resumed at wrong offset: N != 0", which the client surfaces as
RANGE_INVALID: invalid content range. It showed up in 3 of 8 benchmark runs
with an instrumented Create: identical IDs, startedAt values 10 to 60ns
apart. The line predates the recent upload path work.

Writer IDs now come from newWriterID(), a package level func var returning
"upload-" + uuid.NewString(). google/uuid is already a direct dependency of
the module, so no new one is added, and the UUID's hex and hyphens keep the
ID URL safe: it travels in the upload URL and inside distribution's _state
token. The "upload-" prefix is kept because the existing ID test asserts it.

Create now also refuses to overwrite an occupied key, under globalUploadsMu,
rather than evicting the sitting writer. With a UUID a hit cannot be chance,
so failing loudly beats stranding a client that is midway through a layer.

The mock hold server's test upload ID moves to a UUID for the same reason.

Tests: TestCreate_ConcurrentIDsAreUnique releases three Creates from a
shared barrier over 300 rounds and asserts every ID is distinct and every
Create lands its own entry in globalUploads. That one does not reliably
fail against the old code, since the mock path desynchronises the
goroutines, so TestCreate_RefusesDuplicateID covers the guard directly by
overriding newWriterID to hand back an ID that is already taken, and
asserts Create errors and leaves the original writer in the map. Confirmed
it fails with the guard removed.

Evan JarrettandClaude Fable 5.1 831b7757bf appview: never block a writer on budget for its second buffer
Since 56bde61 a large writer keeps one part in flight while the next
buffer fills, and it charged that second buffer to the process-wide
upload budget as the buffer grew. Nothing is released before Commit, so
enough writers mid-growth could hold the whole budget between them while
none of them had reached its peak: no writer could get the bytes it
needed to fill a buffer, so none could reach the Commit that would have
released any. Every Write then sat out the five minute wait cap and
failed. That is a wedge, not backpressure.

The invariant now is that a writer only ever waits for its first buffer.
One full buffer is all a blob needs to finish: the writer can upload each
part where it stands and refill the same buffer. So the second buffer is
taken only when the budget can spare it without waiting, through a
TryAcquire that also leaves a buffer's worth free for a writer that has
not got its first one yet. A writer that cannot have one falls back to
the serial upload it did before 56bde61, and tries again at the next
hand-off, so pipelining comes back as soon as memory does. The second
buffer is charged and allocated whole at hand-off rather than grown into,
which keeps w.charged exactly equal to the arrays the writer holds and
means no later write in the upload asks the budget for anything.

Repro, now a regression test: three writers sharing a budget sized for
two, each filling its whole first buffer before any of them goes on.
Before, 0 of 3 made progress with 64MB of 64MB held; now all three stream
32MB and commit, and the budget comes back whole. The other two new tests
pin both sides of the opportunistic charge: a writer with a free budget
carries on into a second buffer while its part is held on its way to S3,
and a writer given a budget of exactly one buffer still pushes a 48MB
blob as three parts without ever holding more than 16MB.

Evan JarrettandClaude Fable 5.1 56bde61555 appview: keep one part upload in flight while the next buffer fills
A large layer went up strictly one step at a time: fill 16MB from the
client, stop reading, fetch a part URL and PUT the part to S3, reset,
resume reading. While the part was in flight Docker sat on a full TCP
window; while the buffer filled S3 sat idle. Wall clock was receive
time plus send time.

The writer now hands a full buffer to a goroutine that does the hold
call and the PUT, and keeps filling a second buffer from the client.
When that one fills it waits for the previous part, takes its buffer
back, and hands the new one off. At most one part is in flight, so part
numbers and ETags stay ordered, and a blob that never fills a buffer
never allocates the second one. No network runs under the writer lock
on the happy path.

Peak memory for a large upload is now two buffers, 32MB. Both are
charged to the process budget through the existing accounting, the
second as it grows, and the budget floor rises to match so a large
upload can never be refused outright. The 512MB default holds sixteen.

A failed part records a sticky error, closes the writer, and aborts the
multipart from the goroutine that still holds the upload ID; the next
Write, hand-off, or Commit reports the cause. Commit verifies the digest
first, then waits for the flight, sends the final part, and completes.
Cancel waits for the flight, bounded, before aborting so the abort
cannot overtake a PUT that has not yet been issued its upload ID. The
sweeper refuses to reap a writer with a part in flight, since last
activity is only stamped when a part lands.

Tests observe the overlap directly: the fake S3 blocks the first PUT and
the second buffer's writes are asserted to return before it is released,
while the third buffer's writes block. Also covered: the one-part-late
error, Commit waiting, Cancel during flight, peak budget, the sweeper,
and concurrent Cancel and Write under the race detector. The
integration suite passed with a 72MB layer pushed through the pipeline
by three clients.

Evan JarrettandClaude Fable 5.1 7045e84c00 appview: read the sailor profile from the local users row, not the PDS, per request
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.

Evan JarrettandClaude Fable 5.1 47a107058d appview: bound upload buffer memory, reap abandoned uploads, and pin the flush boundary
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.

Evan JarrettandClaude Fable 5.1 f4343d7956 appview: upload small blobs with one presigned PUT, and verify every digest
Every blob went through the multipart machinery: an S3 multipart started
on Docker's initial POST, a hold round trip per part, and a complete on
the hold that finished the multipart, HEADed the temp object, copied it
to its final key, and deleted the temp. For a 2KB config blob that was
three hold calls and six S3 operations. On production data 86% of
distinct layers and every config blob fit in a 16MB buffer, and 49% of
image manifests have no layer larger than that.

The writer now buffers up to 16MB (also the multipart part size) and
makes no hold call until it has to. A blob that never overflows the
buffer is written at Commit with a single presigned PUT to its final
key, via the hold's existing method=PUT presign; the multipart only
starts on the first flush. The hold's completeUpload does nothing the
direct path skips: quota, layer records, stats and scan dispatch all
hang off notifyManifest, which is unchanged.

The buffer starts empty and grows on demand, with the doubling capped so
capacity never overshoots 16MB: a config blob costs kilobytes, and only
layers that approach the threshold fill it.

Bytes are hashed as they arrive. Commit compares the computed sha256 to
the digest the client claimed before any network call, and returns
DIGEST_INVALID on mismatch, aborting a multipart if one was started.
Previously nothing verified the content, so a pusher could store wrong
bytes under a digest in the shared content-addressed space.

Tests observe request counts on a fake hold and fake S3 rather than
return values. The growth test streams in 24KB chunks because
power-of-two chunks land on 16MB by luck and hid an earlier weaker guard.

Evan JarrettandClaude Fable 5.1 034ea5988b hold: report blob size on read presigns so the appview can skip its S3 HEAD
distribution calls Stat before every blob GET and HEAD. The appview's
Stat asked the hold for a presigned HEAD URL and then HEADed S3 with it
purely to read Content-Length for the descriptor: two round trips to
learn one number.

The hold's getBlob response for OCI digests on GET and HEAD now carries
"size". It comes from the records index when a layer record exists (a
SQLite lookup on a new digest index, no network) and from a HeadObject
otherwise, which is where config blobs land. If storage says the object
does not exist the hold answers 404 instead of signing a URL that can
only fail. The PUT and ATProto CID paths are untouched.

The appview builds the descriptor from the reported size and makes no
S3 request. When the field is absent it HEADs the presigned URL as
before, so a new appview works against a hold that has not been
upgraded, and an old appview ignores the extra field. A hold 404 maps
to ErrBlobUnknown.

Tests prove the index answered by leaving the mock bucket empty and
counting zero HeadObject calls, prove the fallback with exactly one, and
count requests reaching the fake S3 origin on the appview side rather
than trusting the returned size.

Evan JarrettandClaude Fable 5.1 61a934debb hold: look crew members up by rkey instead of walking the collection
ValidateBlobWriteAccess, ValidateBlobReadAccess, ValidateOwnerOrCrewAdmin
and getCrewTier each listed every crew record to find one member: open a
carstore session, walk the MST, CBOR-decode each record, compare DIDs.
That ran on every multipart call from the appview, including the part
URL request for every 10MB, and on every getBlob presign, so on a hold
with hundreds of crew each part cost hundreds of decodes.

lookupCrewMember tries the deterministic rkey first (one record read)
and only falls back to the walk on a not-found miss. The fallback is
required: records created before the hash-rkey scheme sit at a TID rkey,
and the boot-time migration that rekeyed them only existed between
e0a2dda and b2d6842, so a hold that upgraded across that window still
has them. Members hit the O(1) path; only genuine non-members pay for
the walk, and they are denied anyway.

Every authorization decision and error string is unchanged. Tests cover
the deterministic hit, a legacy TID-keyed member found only through the
fallback, a non-member, and a storage error surfacing as an error rather
than a silent denial.

Evan JarrettandClaude Fable 5.1 9228579b07 appview: share one HTTP transport across blob proxy requests
NewProxyBlobStore built a fresh http.Client and http.Transport on every
call, and it is called once per registry request because the routing
repository is created per request. So no connection to the hold or to a
presigned S3 URL was ever reused: every XRPC call and every part upload
paid a TCP and TLS handshake, HTTP/2 was never negotiated, the idle pool
settings were dead config, and each discarded transport kept its idle
sockets open for the full 90s timeout.

One package-level transport and client now back every store. Settings
are unchanged; ForceAttemptHTTP2 is explicit to document intent. The
load balancer negotiates h2 on the frontend (416ba4a) but reaches the
hold over HTTP/1.1, so multiplexing stops at the LB. The win is the
handshake and socket churn, not multiplexing.

The struct field stays per-instance so tests can substitute a client.

Evan JarrettandClaude Opus 5 788b9e1053 hold/admin: bound the crew tab's identity lookups, and drop backend HTTP/2
Two corrections to the HTTP/2 change, both found by running it.

UpCloud refuses http2_enabled on a backend that is not TLS:

  invalid_params_properties.http2_enabled='Tls must be enabled to enable HTTP2.'

This load balancer reaches both origins over the private network in cleartext,
so the option is not available here at all, and asking for it failed the whole
provision run with a 400 after the frontend had already been changed. Backend
HTTP/2 is removed rather than made conditional: it would need TLS terminated at
the origins, which is a much larger change than it earns. The frontend is the
leg that mattered, and it is enabled and confirmed live — all three domains now
negotiate h2 by ALPN.

The second correction is more interesting: enabling HTTP/2 did not fix the
symptom it was aimed at, and briefly made it look worse. With the browser no
longer rationing itself to ~6 connections, every row of the crew tab now reaches
the server at once, and the 504s went from a flat 10s to a climbing ladder:

  [HTTP/2 504 10026ms] ... [HTTP/2 504 15230ms] ... [HTTP/2 504 25976ms]

HTTP/1.1 had been hiding a server-side limit by throttling the client. The queue
moved; it did not disappear. What is actually slow is resolveHandle, which calls
live identity resolution per row with no bound of its own, so a DID whose
resolution hangs — a did:web on a host that stopped answering, a PDS that
accepts and then stalls — holds its request open until the proxy gives up. The
crew tab issues one request per member, so a hold with hundreds of crew gets
hundreds of chances to hit one.

resolveHandle now bounds each lookup at 2s. A handle is decoration on a row
whose DID is already rendered beside it, so waiting seconds for one and failing
the row when it does not arrive trades something load-bearing for something
cosmetic. Two seconds is far above a warm cached lookup and far below the
proxy's 10s cut, so a slow DID costs its own row a handle and costs the page
nothing.

The quota lookup on the same handler was the other suspect and was measured out:
records(collection, did) is indexed and the aggregation returns immediately on
the production database.

This does not remove the N+1 — the tab still issues one request per member, and
a batch endpoint is the real fix. It removes the failure.

Verified: the guard is covered by a test using a directory that hangs until its
context is cancelled, asserting both that the call returns near the bound and
that it did not return suspiciously early. make lint 0 issues, make test green
across 44 packages.

Evan JarrettandClaude Opus 5 8d7ccd7cb7 apply go fix modernizations across the workspace
`go fix` carries the modernize analyzers now, and the tree had drifted behind
them. This is the mechanical result, reviewed rather than trusted: the tool is
capable of rewriting code into something that no longer tests or does what it
did, so every non-test change was read individually and the concurrency-bearing
packages were re-run under -race.

Production code, four changes, all semantics-preserving:

  - leases/manager.go: wg.Add(1) + go + defer wg.Done() becomes wg.Go. The
    comment above that function turns on Add happening before the goroutine
    starts, so that a Wait cannot return before the worker has run. wg.Go does
    the Add synchronously on the calling goroutine, so the invariant it
    describes still holds.
  - auth/token/handler.go: strings.Fields -> strings.FieldsSeq, same splitting,
    iterated rather than allocated.
  - hold/gc/gc.go: a hand-written map copy -> maps.Copy.
  - hold/pds/scan_broadcaster.go: three-clause loop -> range over int.

The rest are tests. The one worth naming is carstore_contention_test.go, where a
careless rewrite could have quietly stopped exercising contention: go fix
converted the reader and side-table goroutines to loopWG.Go but correctly
declined to touch the writer loop, which passes its index as a parameter. The
writer/reader/side-table shape and the stop channel are unchanged, so the test
still contends over the same carstore transactions.

Verified: go build for hold and appview, `make lint` 0 issues, the deploy and
credential-helper modules 0 issues, `make test` green across all 43 packages,
and -race green on leases, hold/pds, hold/gc and auth/token. The scanner module's
two lint findings are unchanged from HEAD and are in files go fix never touched.

Kept separate from the HTTP/2 commit so that one stays readable, and so this can
be reverted on its own if a modernization turns out to matter.

Evan JarrettandClaude Opus 5 416ba4a2eb serve HTTP/2, and reach it through the load balancer
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.

Evan JarrettandClaude Opus 5 96b48f4b3d hold: gate presigned PUT behind write access, and validate blob identifiers
com.atproto.sync.getBlob took its S3 operation straight from ?method= with no
allowlist and passed it to GetPresignedURL, whose switch mints a presigned PUT.
The ATProto sub-handler is public per the ATProto spec, and the OCI one gates
on ValidateBlobReadAccess, which passes anonymous callers on a public hold by
design. So an anonymous caller could obtain a fifteen-minute presigned PUT into
the hold's own bucket, over the avatar, the OG-card thumbnails, stored SBOMs
and vulnerability reports, or the OCI layer space. Holds sharing a bucket
widened it.

The defect is that a read check was gating a write. PUT now requires captain or
crew with blob:write via the existing ValidateBlobWriteAccess, rather than a
new parallel gate. Reads are untouched: ATProto GET and HEAD stay public,
OCI GET and HEAD keep the read check. An unknown method is a 400 rather than
falling through to a 500 from the presign switch.

The identifiers reached object storage keys unvalidated, which the tests showed
was not theoretical: cid=../../../../etc/passwd presigned a key containing that
path, and an OCI digest of sha256:aa/bb presigned across a shard boundary. A
digest is now sha256 plus exactly 64 lowercase hex, shaped after the scanner's
ParseDigest, and a CID must decode and round-trip to its canonical encoding.
Validation runs before the auth gate, so a malformed identifier is a 400 even
for an authorised caller.

Verified before changing anything that no legitimate caller reaches PUT
presigning. Pushes upload through the multipart endpoints, which live inside
requireBlobWriteAccess and use PresignUploadPart; every getBlob caller in the
appview, the scanner and the handlers sends GET, HEAD or nothing, and the
distribution route can only produce GET or HEAD.

One existing test asserted that an unauthenticated PUT returns a presigned URL.
It was pinning the vulnerability as intended behaviour and is replaced by
coverage of both the refused and the authorised cases.

Evan JarrettandClaude Opus 5 c44a874090 hold: set busy_timeout on every pooled connection, not just the first
A PRAGMA is per-connection, and database/sql opens one connection per
concurrent caller. hold_db.go and scan_broadcaster.go each set
busy_timeout = 5000 with a one-shot query against the pool, which configures
whichever connection happened to serve it and leaves every other writer at
zero. Probing the live pools showed exactly that: conn 0 at 5000, conns 1 and 2
at 0. That is the database is locked on COMMIT, and the carstore had no
busy_timeout and no WAL on any connection at all.

Opening a database now goes through a connector that runs the PRAGMA on every
connection the pool creates, ported from the appview, which had already solved
this. Applied to the carstore, the shared hold DB, the records index, the event
broadcaster and the scan broadcaster. In-memory databases are left unwrapped,
since libsql gives each connection its own, and the embedded replica path still
skips PRAGMAs because a remote rejects them.

WAL is not a new risk: production was already WAL, because journal mode is a
persistent property of the file and OpenHoldDB has been setting it. This makes
the carstore's own opener agree rather than leaving standalone and test
databases in rollback-journal mode. A database that refuses WAL logs a warning
instead of failing boot, so a network mount cannot stop the hold starting.

NewHoldPDS's file mode opened the same file a second time for the records
index; it now shares the carstore's pool. Two pools on one file buy nothing,
since SQLite's write lock is per database, so the second only adds contenders.
Production already shared a pool and was unaffected by that half.

Note for anyone reading OpenHoldDB: its foreign_keys pragma has the same
one-connection scope, but libsql reports foreign_keys on for every fresh
connection anyway, so it is decorative rather than broken.

Evan JarrettandClaude Opus 5 3ceedc8bb5 hold/gc: time an orphaned record from when it was seen, not when it was written
The aux-record sweep decided whether a record was old enough to collect from a
timestamp inside the record body, which for scan records is scannedAt. Every
rescan rewrites that, so the grace clock reset continuously and a hold with a
rescan_interval shorter than the grace period could never collect an orphaned
scan record at all.

Grace now measures how long a slot has been continuously observed orphaned
across analysis passes. The key deliberately excludes the CID so a rescan
rewriting the record in place does not restart the clock, and the check runs
last, after the manifest, reachability and co-ownership tests, so a record
judged live never accrues orphan age. A pass that errors partway commits
nothing rather than resetting the clock on slots it never reached.

The clock is in memory, so a restart forgets every observation and each
surviving orphan starts its grace again. That delays collection and can never
advance it, which is the safe direction, but it does mean a hold restarting
more often than the grace period will not collect aux orphans. Persisting it
wants a table in pkg/hold/db and is left for later.

Applied to both aux collections rather than only to scan records. For image
configs the new rule is strictly more conservative, since a record cannot be
observed before it is written, and a per-collection table of which timestamps
are safe to trust is a thing to maintain and to get quietly wrong.

One widening beyond the reported bug, called out rather than left to be found:
a record whose body timestamp is unparseable used to be kept forever, because
the zero time read as in-grace. It is now collected on the normal schedule,
having cleared every other guard plus a full grace period.

Also corrects the comment claiming these records hold no blob references. Scan
records carry sbomBlob and vulnReportBlob; they live under a prefix the blob
sweep never walks, so deleting the record frees nothing, and a future sweep for
that space must read those fields before the record goes.

Evan JarrettandClaude Opus 5 61deadc124 hold: reuse stored scan blobs when a rescan finds nothing new
The stale-scan loop rescans an image on a schedule and handleResult uploaded
both artifacts every time, so each pass wrote a fresh SBOM blob and orphaned
the one before it. Nothing reclaims those, because GC walks only the OCI blob
prefix and scan artifacts live under /repos.

Keep the stored blobs when the record already on file was written by this same
scanner version and carries a vulnerability-report reference equal to the one
this report would be stored under, then keep each blob individually and only if
it is still in S3.

The report reference alone is not quite enough evidence on its own: the report
lists matched packages, not every package, so an SBOM could gain a package with
no known CVEs and leave the report byte-identical. Content is pinned by the
manifest digest, so that can only happen across a scanner or Syft change, which
is what the version clause closes. It is inert until that constant moves, and
one comparison is cheaper than remembering to add it at the moment it first
matters.

Every failure path declines to reuse, which costs an upload and never costs
correctness, including the reuse check's own timeout, which is carved out of
the upload budget rather than given its own so a slow read cannot eat the
deadline it stands in for. A record whose earlier upload failed heals on the
next rescan, keeping the report and rewriting only the missing SBOM.

scannedAt still advances. runStalePass selects on it, so freezing it would make
every deduplicated record permanently stale and rescanned forever, which costs
far more than the bytes saved.

A scanner running with vulnerability scanning off sends no report, so there is
no stable digest to compare and its SBOM still churns. Closing that means
either parsing SPDX in the hold to normalise a timestamp and a UUID, or a
lexicon change; a test pins the gap rather than leaving it to be rediscovered.

Note for anyone extending GC to /repos later: a live SBOM object used to be
rewritten on every rescan and so was always young. It now keeps its original
mtime for the life of the content, so an age-based rule there would delete
referenced blobs.

Evan JarrettandClaude Opus 5 1853c0c1d3 hold/scanner: detect dead connections and get storage off the reader
Three defects that all turn on whether the hold knows what a scanner is doing.

Neither end had a keepalive, a read deadline, or a read limit, so a half-open
connection was invisible until some other timeout fired. That got worse with
capacity-aware dispatch: a dead-but-connected scanner holds its advertised
worker count out of the budget and keeps winning jobs. Both ends now ping every
30s against a 90s read deadline, so three unanswered pings condemn a
connection. Detection takes about 90 seconds, after which the existing
reconnect grace reclaims the rows, against the 60-minute queueing timeout that
was previously the only escape. Liveness decides when a scanner is gone; the
grace window decides when its work is reassignable.

Read limits are asymmetric and deliberately generous, because exceeding one
closes the connection rather than truncating, which would turn a large but
legitimate result into a permanent retry loop. Write deadlines were absent
everywhere; the scanner in particular held a mutex across an unbounded write,
so a wedged write silenced it without disconnecting it.

handleResult did two S3 uploads and a CAR commit inline on the reader
goroutine, so a slow S3 looked exactly like a dead scanner. Terminal messages
now go to a per-subscriber storage goroutine while acks and starts stay on the
reader. One goroutine, not a pool: every path ends in CreateScanRecord, which
serialises on the repo lock anyway, and ordering is worth more than parallelism
that cannot be used. Uploads and the record write get separate budgets, so a
stalled upload cannot spend the time the record needs and the record write
stays unconditional.

checkPredecessor cached an inconclusive answer as a definitive negative in a
map that is never reset, so one unreachable hold meant its manifests were never
scanned again for the life of the process. gc.go already carried the corrected
logic for the same problem; this follows it rather than inventing a second
approach, and also stops treating an unparseable captain record as definitive.

The test PDS had to move off ":memory:", which go-libsql scopes per connection:
writing a scan record from any goroutine but the caller's got a connection with
no tables. That was invisible while every record write happened inline.

Evan JarrettandClaude Opus 5 a63f668de0 scanner: fix five crash and halt classes found by a pipeline audit
An audit of the scan pipeline and the hold side of scanning found several
ways scanning stops without saying so. Each fix here was written test-first:
a test expressing the wanted behaviour, confirmed failing for the right
reason, then the change.

A summary-less result crash-looped both processes. worker.go dereferenced
result.Summary unconditionally, but processJob only sets it when Grype runs,
and SendResult puts the nil on the wire before the scanner dies on it, so
handleResult's unguarded log killed the hold too. A nil Summary now means
"not scanned for vulnerabilities", deliberately distinct from "scanned, found
zero" — inventing a zeroed summary would report every image as clean when
Grype never ran. The hold writes a record rather than orphaning the uploaded
SBOM, and the appview renders an "SBOM only" state instead of a green Clean
badge.

The Grype database could wedge with no way back short of a restart. All three
throttles in loadVulnDatabase were guarded by vulnDB != nil, so a scanner
holding no provider retried a full download on every scan under the exclusive
lock. Two earlier attempts at this bug each added one more condition to the
same chain; this replaces the chain with a single decision function over a
state snapshot, consulted by both call sites so they cannot disagree. That
disagreement was itself a bug: the 50-scan reload had never once executed.

Two independent halts. An unparseable frame was dropped in silence, stranding
a row that held the hold's only dispatch slot forever; it is now answered
"skipped" on first delivery. The 10-minute sweep leaked the in-flight digest
and wrote no record, permanently retiring one image per timeout.

A digest went unvalidated into filepath.Join and os.Create, so a layer digest
of sha256:../../../x wrote outside the scan directory, and nothing verified
that downloaded bytes hashed to the digest naming them. Digests come from
records in a user's own PDS. Both are fixed together: verification is what
makes an escaping write self-defeating.

Concurrency did not work on either axis. The proactive capacity gate was
depth-one hold-wide, so neither extra workers nor extra scanner processes
received work. Depth is now the sum of the worker counts scanners advertise on
connect, the gate is scoped to proactive work, and dispatch prefers the
least-loaded scanner. Disconnects no longer hand a running scan to someone
else: a scanner keeps a stable per-process identity and reclaims its own rows
within a grace window, while a process that truly restarted returns with a new
identity and has its work reclaimed, which is correct because the restart did
lose it.

The hold's scanning deadline measured queueing rather than scanning, because
the scanner acks on receipt and handleAck never refreshed assigned_at. A new
"started" message, sent by the worker that dequeues the job, separates the two
budgets. An older scanner never sends it and falls under the queueing budget,
which is more forgiving than the deadline it gets today.

Adds an in-process mock hold and an e2e harness that runs the real client,
queue and worker pool, seeded with 84 real manifest records fetched from a
live PDS. Real image layouts and the Grype database are fetched by scripts and
gitignored; suites needing them skip cleanly, so the default run stays offline
and fast.

Evan JarrettandClaude Opus 5 f16a8eaa82 appview: warn about a deprecated chart on the tab people actually land on
8487258 added the deprecation notice to the shared helm metadata partial, on
the understanding that both the Overview and Chart tabs rendered it. Only the
Chart tab does. The Overview panel renders the README and never touches chart
metadata, so a deprecated chart carried no warning on the default landing tab.

The notice is extracted into a shared helm-deprecation-notice block, so the
copy lives in one place, and the Overview panel renders it server-side as the
first element in the panel. Deprecation decides whether you should use the
chart at all, so it belongs in the first paint rather than arriving a beat
later from a lazy fetch.

Getting the data there costs nothing extra. The page already made a blocking
hold call for layer count, and for a chart that call was wasted: a helm config
blob is Chart.yaml, which has no history key, so the count always came back 0
and fell through to the database. That call is now FetchHelmChartMeta instead,
against the same XRPC endpoint, so a chart page makes one hold call rather than
two and the displayed layer count is unchanged. A container image never fetches
chart metadata and its path is byte-for-byte the old code.

Failure follows the layer-count precedent: log at warn, leave the metadata nil,
render the page. An unreachable hold means no notice, not a broken repository
page. The tradeoff against the lazy version is that a slow-but-up hold now
delays the whole page, bounded by the same 10s the page already accepted.

A container image emits no element at all rather than an empty one, so the
space-y-4 stack spacing is untouched.

Evan JarrettandClaude Opus 5 e542dd12f6 appview: keep the port in the registry host printed to users
On the dev stack (registry_domains: ["127.0.0.1:5000"]) the /auth/token failure
guidance said `docker login 127.0.0.1`, dropping the port docker needs. The
message exists to tell a stuck developer what to run, so a command that cannot
work is the whole defect. Production is unaffected, both registry domains being
port-free.

The stripping itself is deliberate and stays: NormalizeService removes the port
so JWT audiences match the port-stripped routing host. Removing it would
desynchronize the service key from the routing key.

The unstripped form turned out to survive in only one place. resolveService
returns a key from h.services, which SetServices normalizes, and cfg.Auth.Services
is normalized too by deriveServices, so neither holds the original. Only
cfg.Server.RegistryDomains, straight off the YAML, does, and it was never
reaching the token package.

Adds a display-only map keyed by the same NormalizeService function the other
two key on, so a resolved service always maps back to the entry it came from,
and a multi-domain deployment prints the domain the client is authenticating
against rather than the primary. Collisions take the first configured entry,
matching deriveServices' own first-wins dedupe. A miss falls through to the
normalized name, which is today's behaviour.

Audiences and routing are untouched, proven by a test that mints a real token,
parses the JWT and asserts aud is still the normalized host.

The wiring line landed in the previous commit, both changes having been made in
server.go at the same time.

Evan JarrettandClaude Opus 5 3589473feb appview: run the hold purge on a worker pool, not the request context
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.

Evan JarrettandClaude Opus 5 b4fccce4d1 hold: actually send subject, so the attestation scan guard can fire
The hold declines to enqueue a scan when a pushed manifest has a subject, which
is how it means to skip attestations, signatures and other referrer artifacts.
The AppView never sent one: notifyHoldAboutManifest built mediaType, config,
layers and manifests, and #manifestInfo defined only those four. So the
condition was always true, the guard never fired, and every referrer artifact
was enqueued for scanning.

The AppView already parsed subject. NewManifestRecord unmarshals it into
ManifestRecord.Subject, and Put hands that same pointer to
notifyHoldAboutManifest. The value was in scope and simply never serialized, so
this is one missing marshal step rather than a missing parse.

Adds subject to the lexicon as a #blobInfo ref, and mediaType to #blobInfo,
which config has always sent and the hold has always parsed. That only makes the
schema honest about what is already on the wire.

Hoists the hold's anonymous request struct to a named type with IsMultiArch,
IsReferrer and HasScannableContent, so the predicate is written once and
testable without standing up a HoldPDS.

Both directions degrade safely. An older hold ignores the unknown key and
behaves exactly as today, so shipping the appview alone is harmless but achieves
nothing until the hold catches up. An older appview sends no subject, leaving
the manifest enqueued as before.

Complements dfd604b rather than duplicating it. That guard lives in the scanner
after a job is created and dispatched, and catches unscannable work from any
source including the hold's proactive discovery pass. This one stops the row
being created at all, which matters because the row that froze all scanning for
nine days was exactly such an attestation. One gap neither closes: an
attestation with tar-shaped layers pushed by an old appview.

Evan JarrettandClaude Opus 5 9566201377 appview: give the confirm modal an accessible name and a focus trap
The modal guards tag deletion, device revocation and webhook deletion, so it is
the wrong control to leave unlabelled and escapable.

Note the original report was half wrong: role="dialog" and aria-modal="true"
were already set on the outer element, and are in the deployed bundle. The
observation was most likely taken against the inner .modal-box. Neither was
added here.

What was actually missing: the h2 existed but nothing pointed at it, so a screen
reader announced a dialog with no name; and the only focus management was
focusing Cancel on open, so Tab walked straight out into the skip link and page
header behind the backdrop.

Adds aria-labelledby and aria-describedby with sequence-suffixed ids so two
modals cannot cross-reference. aria-describedby matters more than usual here:
none of the three call sites' messages contain ". ", so the title is always the
generic "Are you sure?" and the specific text is the body.

The trap re-queries on each keypress rather than caching at open, and handles
three cases: focus escaping to body gets pulled back, first plus Shift+Tab wraps
to last, last plus Tab wraps to first. Focus is restored to the opener on every
close path, guarded by document.contains, because confirming a tag deletion
fires an htmx swap that can remove the button that opened the modal. Restoration
happens before onConfirm so htmx sees a sane focus state.

Native <dialog> would give the trap and Escape for free, but it renders in the
top layer while this is styled entirely with daisyUI .modal classes that assume
a positioned div, so converting means CSS work plus the seamark theme fork.
Worth doing as its own change, not smuggled into this one.

Includes the bundle rebuild, since nothing in the dev loop keeps that artifact
current.

Evan JarrettandClaude Opus 5 dbb195a4ab appview: process daily stats, and drop the dead README branch fallback
io.atcr.hold.stats.daily was handled in the backfill collection list and in
processor.go's dispatch, but missing from isRelevantCollection, which gates
events before ProcessRecord ever sees them. So daily stats records arrived over
the socket and were discarded at the worker, and the trend charts that read them
got nothing live. This is the "present in one list, missing from the other"
shape CLAUDE.md's firehose checklist warns about. Checked the whole class: this
was the only gap. LayerCollection and ImageConfigCollection are absent
deliberately, having no processor handler, and the test now pins that intent.

Note this is currently masked by the relay outage, so fixing the relay alone
would not have restored the charts.

Separately, the README resolution tried "main" and fell back to "master", but
DeriveReadmeURL never fetches: it parses the source URL and interpolates the
branch, returning empty only for an unsupported platform, which is
branch-independent. So if the main call returned empty the master call returned
empty for the same reason, and the fallback could never fire. Removed, with a
comment recording that a branch fallback has to happen at fetch time after a
404. The other two call sites already do exactly that.

Evan JarrettandClaude Opus 5 7a0769d8e4 appview: three small UI fixes, empty state, icon sizing, aria-selected
Artifacts filter had no empty state: filtering to zero matches left a blank
panel, indistinguishable from something being broken. It now uses the existing
state-empty partial, with no CTA since the filter input is right there. Rows
appended by Load More now also obey the active filter, which is a change to
existing behaviour but is required for the empty state to be truthful.

The tag icon beside the tag selector computed to 5.44px by 24px on every repo
page: the class was right, the flex parent was shrinking it. Adds shrink-0 to
that instance only. 31 other icons are direct flex children without shrink-0
and are left alone, since a site-wide sweep found only this one squeezed.

Digest-page scan tabs set role="tab" but never aria-selected, while the
repo-page tabs do. Both are now set server-side so first paint is correct, with
JS keeping them in sync afterwards, following switchRepoTab's pattern. The
diff-content tabs had the identical defect and are fixed too, since the handler
is generic over radio tabs and leaving them out would have meant attributes set
by JS but never by the server.

Includes the bundle rebuild for these and the two /auth/token-adjacent JS
changes, since nothing in the dev loop keeps that artifact current on its own.

Evan JarrettandClaude Opus 5 9d8bd513da appview: render the install scripts from config instead of shipping ATCR's
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.

Evan JarrettandClaude Opus 5 2743445e65 appview: fix two /auth/token defects, wrong login host and dropped scopes
Both are pre-existing and were found while working on finding 27.

sendAuthError built its "docker login <host>" line from r.Host. /auth/token is
served on the UI domain as well as on every registry domain, and the
WWW-Authenticate realm points at the UI domain's copy, so a client following
the realm was told to run "docker login seamark.dev" - the one host that
deliberately refuses /v2/* with an OCI UNSUPPORTED error pointing at
seamark.cr. It now uses the service resolved for the token, which is the
registry domain, falling back to the deployment's primary rather than to
r.Host. The single-domain case still prints a host that serves /v2/, and an
unconfigured service supplied by the client cannot steer it.

Separately, the scope parameter was read with .Get, taking the first value
only. The Docker token spec allows scope to be repeated, so a client asking for
two repositories was issued a token covering one and got a 401 on the other.
Both wire forms are now flattened, on the GET query string and on the OAuth2
POST body, which had the same defect via PostFormValue.

Empty and whitespace-only values are dropped. Exact duplicate scope strings
collapse, but two entries naming the same repository with different actions are
left alone: merging them would union the action sets, and every gate downstream
is written only to narrow.

More entries now reach the anonymous gate added in af7522b, which is the
intended effect. Its per-entry verdict is unchanged: public entries survive,
private ones are dropped, and an all-private request still gets the challenge.

Evan JarrettandClaude Opus 5 84872580a3 appview: show a chart's deprecation where people actually look
digest.html rendered a Deprecated chip, but the shared helm-metadata partial
never read .Deprecated, so the repo page carried no deprecation signal at all.
The data was already on the struct; this was a display omission.

The notice leads the metadata card, above the description: deprecation decides
whether you use the chart at all, so it has to be read before the prose that
sells it. It uses the alert/alert-warning callout the codebase already uses for
this kind of thing, including in the adjacent helm-digest-content partial,
rather than a bare badge. A lone small badge reads as a stray tag once it is
outside the digest page's row of status chips, and leaves no room to say why it
matters.

The digest page now shows deprecation twice, deliberately: its header chip is
the scannable signal above the fold, and this carries the explanation further
down. Removing the chip would push the only signal below the install command,
which is the burial this fix is meant to undo.

Note the repo page's Overview tab, which is where most people land, still shows
nothing: it renders the README and never touches chart metadata. Only the Chart
tab gains the notice here.

Evan JarrettandClaude Opus 5 0490278fb8 appview: don't report a failed README guess as an error
Four of the twelve home-page repos showed "We couldn't load the README, it may
be rate-limited or private". The URL in those cases was not configured by
anyone: it was derived from org.opencontainers.image.source, a label images
inherit from their base image, so the raw URL named an unrelated project and
404ed. A 404 on a URL the appview guessed is an expected outcome the owner
cannot act on.

The failure flag is now set only when the owner actually pointed us at the URL,
via the io.atcr.readme annotation. A derived URL that fails renders as if there
were no README. Both paths keep their debug log, now carrying an "explicit"
field so the two cases stay distinguishable.

Render failures are suppressed for derived URLs too. The panel's copy and its
"Edit README" action address an owner who configured a source; on a derived URL
there is no configured source, and content that failed to render is very likely
another project's README anyway.

This is the alarming half of the finding. Rendering the wrong project's README
when the fetch succeeds is the larger half and is untouched: there is no
reliable way to detect an inherited label, since the only signal is
org.opencontainers.image.base.name, which is not always set.

Evan JarrettandClaude Opus 5 44a17cbcdc appview: stop the upgrade banner inventing an improvement across arch mismatch
On a public repo, to anonymous visitors, the digest banner read "2 fixes, 12
Critical / 27 High / 26 Medium vulns, -22 layers, -53.6 MB" while the same page
showed 244 vulnerabilities and Layers (22), and its own "View diff" link landed
on "Layers 22 -> 22, every layer Unchanged".

Platform matching only ran when both sides were manifest lists. The comment
after that block said the mismatched case would "fall through and show a basic
banner without layer/vuln details", but no such branch was ever written and
nothing guarded the fallthrough, so execution continued into the layer and vuln
computation with the unresolved originals still in place. The newer side was
the multi-arch index, which carries no layers of its own and is not scanned, so
all 22 layers of the other side read as removed and the vuln delta was computed
against an absent scan.

Returns 204 for either mismatch direction, as the no-common-platform path
already does.

The promised "basic banner" is not implementable as the function stands, which
is presumably why it never appeared: the template renders only NewerTag,
DiffURL and Summary, and DiffSummary is nothing but deltas, so a delta-less
banner collapses to the tag name and would be suppressed by the existing
"nothing meaningful changed" guard anyway. The comment is replaced with one
that says what is actually true.

Showing a real banner here would mean resolving the index to the child matching
the single-arch side's platform, and that side's os/arch is not in the appview
DB at all: Platforms is populated only for manifest lists and the manifests
table has no os/arch columns. It would need either a config fetch from the hold
at render time or denormalising os/arch during ingest. Not attempted.

Evan JarrettandClaude Opus 5 39919cc832 appview: stop webhooks reaching private addresses
The URL check accepted http:// while telling the user "must be https", and
guarded no addresses at all. POST /api/webhooks with http://127.0.0.1:9/hook
returned 200 and created the webhook, so both scheduled deliveries and the
synchronous Test button would dial arbitrary destinations from the appview
host, on demand, for any authenticated user. Loopback, link-local (including
the cloud metadata endpoint at 169.254.169.254) and RFC1918 were all reachable.

Enforces https, and refuses non-public destinations.

The load-bearing half is the dial-time check, not the creation-time one. An
attacker controls their own DNS, so a hostname that resolves publicly when the
webhook is created can resolve to loopback when it is delivered, and a
creation-time check cannot see a redirect either. The guard is therefore a
net.Dialer Control hook on the delivery client, which inspects the resolved
address on every connection attempt. Transport.Proxy is explicitly nil:
honouring HTTP(S)_PROXY would route around the Control hook and hand the
bypass straight back. Redirects are re-validated per hop and capped at 3.

The creation-time check stays so the user gets an immediate, comprehensible
error instead of a silent delivery failure later.

IPv4-mapped IPv6 is unmapped before every check, so ::ffff:127.0.0.1 and
friends hit the IPv4 rules. Ranges with no net.IP helper are listed explicitly:
CGNAT, NAT64, ::/96, TEST-NET and reserved space.

Both outbound paths are covered, since the scheduled dispatcher and the Test
button both funnel through attemptDelivery. The dispatcher's other client is
deliberately left unguarded: it fetches quota stats from holds, which
legitimately live on private addresses, and those URLs are not user-supplied.

Note this removes the ability to point a webhook at a localhost receiver in
local development. There is deliberately no environment-variable escape hatch,
since a security toggle read from the environment is the same bypass wearing a
nicer coat.

Evan JarrettandClaude Opus 5 dfd604b106 hold/scanner: stop one undispatchable job freezing all scanning
Vulnerability scanning produced nothing across the whole deployment for
nine days, from 2026-08-25 01:20:48 until a scanner restart on 2026-09-03.
The scanner was connected and idle, the hold's discovery pass kept
reporting unscannedFound=15 every four hours, and no scan_jobs row was
created in that entire window.

hasActiveJobs counted pending, assigned and processing rows globally with
no age bound, and waitForCapacity spins while it is true. dispatchLoop
calls it before popping any candidate, so a single pending row that never
reached a terminal state reported "busy" forever: discovery kept pushing
candidates into unscannedQueue and nothing ever popped them. That is why
the symptom was an empty queue rather than a growing one.

Nothing papered over it because push-triggered enqueue only fires for
owner or a tier with scan_on_push, which in production means pro alone.
All 210 manifests pushed to this hold in that window came from free,
supporter, or accounts with no crew row, so the frozen proactive loop was
the only source of jobs.

Nor could it recover on its own. Only Enqueue and drainPendingJobs
dispatch a pending row, and drainPendingJobs runs only when a scanner
newly connects; reDispatchTimedOut considered assigned rows only. The
hold had been up since Aug 14 and the scanner since Aug 21 on the same
websocket, so the drain path had not run since the row appeared.

So bound the capacity gate to pending rows younger than pendingStaleAfter,
give reDispatchTimedOut a pending reclaim, and check RowsAffected on the
assign UPDATE now that two dispatchers can race for a row. waitForCapacity
warns and names the blocking jobs after ten minutes without capacity,
because the failure mode above was completely silent.

Two adjacent fixes for the same outage. The scanner never called
InitLogger, so log_level and log_shipper were dead config and an idle
scanner was mute, which is what made nine days invisible. And skipReason
now also skips a job whose layers contain nothing tar-shaped: the job that
wedged this queue was an in-toto attestation whose config mediaType is an
ordinary image config, so the existing config-type check missed it and
buildOCILayout would have handed Syft an empty image.

The regression tests were verified against the old logic first: three of
them fail on it and pass on the fix.

Evan JarrettandClaude Opus 5 af7522b154 appview: stop /auth/token granting anonymous pull the registry will refuse
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.

Picks up the two JS changes in this batch: the crane destination argument in
updatePullCommand (app.js) and syncDiffMenu (repository.js).

The bundle is a committed build artifact, and nothing in the dev loop keeps it
current on its own. Air's pre_cmd is go generate and its cmd is a Go build; it
never invokes esbuild. Bundling happens in npm run js:watch, a separate
process. So a src-only change leaves the committed bundle stale until someone
runs npm run js:build by hand, which is how cbd0c5f came about.

Without this both fixes are invisible in a served page, and the crane one is
half-live in the worst way: first paint carries the destination because that
comes from the Go template helper, while the dropdown re-render does not.

Evan JarrettandClaude Opus 5 85f312f953 appview: refuse /v2/_catalog with UNSUPPORTED, and send Allow on every 405
/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.

Evan JarrettandClaude Opus 5 8bc6d65e1e appview: emit crane's mandatory destination in the pull command switcher
The client switcher built every command as "<client> pull <ref>". That is
valid for docker, podman, buildah and nerdctl, but crane requires a
destination:

  $ crane pull seamark.cr/user/bench8x1:v2
  Error: requires at least 2 arg(s), only received 1

So selecting crane handed the user a command that cannot run. pullPrefix is a
prefix-only helper, which is precisely why it could not express this; add a
matching pullPostfix that returns " <image>.tar" for crane and "" for
everything else, including "none" (image reference only), which must get
neither prefix nor postfix.

Both render paths change together, since fixing one leaves the bug visible in
the other: the Go template helper paints first, and updatePullCommand in
app.js re-renders when the dropdown changes.

Repository names may contain slashes, so only the last path segment is used —
otherwise the destination would name a subdirectory that does not exist. A
name ending in "/" yields no destination at all rather than a bare ".tar",
on the grounds that a visibly wrong-arity command beats silently writing a
hidden file. That input is not reachable through the real repo-name path.

The test asserts the whole command string rather than just the postfix, so it
covers the prefix/postfix interaction and the "none" case where both vanish.

Evan JarrettandClaude Opus 5 3158460298 appview: hide the current tag from the repository Diff dropdown
The Diff menu listed every tag including the one being viewed, and clicking
that entry did nothing: diffToTag returns early on to === currentTag, with no
navigation, no toast, no feedback.

Fixed in JS rather than in the template, which is the part that is easy to
get wrong. #diff-dropdown sits outside #tag-content, and the tag selector
block is marked "stays in DOM, never swapped" — so a {{ range }} filter would
be correct on first paint and stale after the first htmx tag swap, omitting
the originally loaded tag and re-including the newly current one. Same dead
entry, harder to see.

syncDiffMenu() reads the live value from #tag-selector and is called from
initTabs(), which already runs on load and again from the htmx:afterSettle
handler for #tag-content, so it stays correct across swaps.

Hidden rather than disabled: a disabled row still takes space and still reads
as an item to a screen reader, and "diff against the tag you are already on"
is meaningless rather than temporarily unavailable. Uses style.display to
match filterTags() in the same file, since daisyUI's .menu li rules outrank
Tailwind's .hidden.

The template guards the dropdown with {{ if gt (len .AllTags) 1 }} and tag
names are unique per repo (tags PK is did+repository+tag), so exactly one
entry is ever hidden and the menu can never end up empty. The early return in
diffToTag stays as a backstop.

Pre-existing, not a deploy regression. The baseline missed it because the
test repo had one tag, so the check skipped.

Evan JarrettandClaude Opus 5 1631898005 appview: give every Repository() error an OCI code instead of 500 {}
A user with an unresolvable defaultHold (did:web:localhost%3A8080) got HTTP
500 with a body of literally {} on every request in their namespace, and
crane retried it three times because 500 is retryable.

The cause is in the distribution library. handlers/app.go:755 switches on the
error type returned by Repository() with cases for ErrRepositoryUnknown,
ErrRepositoryNameInvalid and errcode.Error, and no default. A bare fmt.Errorf
matches none of them, so context.Errors stays empty; ServeJSON then finds no
ErrorCoder, leaves sc == 0, falls through to 500, and Errors.MarshalJSON
renders the nil slice as {} via omitempty.

So every error leaving Repository() must be coded. Four were not:

  hold URL unresolvable  -> 404 NAME_UNKNOWN when errors.Is
                            atproto.ErrHoldDIDPermanent, else 503 UNAVAILABLE
  no hold DID configured -> 500 UNKNOWN, but with a body and a log line
  invalid image name     -> 400 NAME_INVALID
  name missing an owner  -> 400 NAME_INVALID

The permanent/transient split is the point: a DNS blip must stay retryable,
but a did:web that can never resolve must not be retried at all. Stored user
data that cannot resolve is a 4xx condition, not a server fault, and the
NAME_UNKNOWN message now names the hold so the owner can fix their profile.
The hold DID is already world-readable in their sailor profile record.

Tests assert through a helper that replays distribution's exact type switch,
so an uncoded error still surfaces as 500 {} and the assertions bind to the
real behaviour rather than to the constructors.

Does not address the logrus line at app.go:757, which fires unconditionally
before the type switch and cannot be avoided by any returned error type.

Evan JarrettandClaude Opus 5 2ee5a35525 appview: stop the schema-drift check reporting phantom index differences
reportSchemaDrift logged 76 differences on every boot, all false positives:
38 indexes each reported twice, once as missing from the database and once
as present but undeclared. The only difference was a single space before the
column list.

The two sides of the comparison are built differently. referenceSnapshot()
applies schema.sql to a local in-memory libsql, which stores the CREATE text
verbatim as "ON t(col)". Production is an embedded replica syncing to Bunny,
whose parser re-emits normalized DDL as "ON t (col)". describeIndexes
collapsed whitespace runs but could not normalize a space that exists on one
side only, and SchemaDrift compares by exact string.

Normalize whitespace adjacent to ( ) and , so both spellings converge. Space
after ) is deliberately left alone, and the space before DESC is untouched,
so column order and direction still have to match.

This mattered because the check exists to catch a migration recorded but not
executed (0004 was, which is why 0009 exists). At 76 phantom findings, real
drift would have been one line among 77, under a hint telling the operator to
write a corrective migration that is not needed. The first boot after this
lands is the first honest reading of that warning.

The existing tests all passed because they run local-only, which is exactly
how this shipped.

Evan JarrettandClaude Opus 5 a63b839613 appview: gzip UI and static responses, leaving /v2 alone
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.

Evan JarrettandClaude Opus 5 cbd0c5f05c appview: rebuild the JS bundle so the committed asset matches src
The tracked bundle predated a219df9, so it carried neither the
alert-error match in testWebhook nor plainTextReason's 400 branch. Any
deploy that copied the committed asset without regenerating would have
shipped the old JS and findings 13, 15 and 17 would have looked unfixed.
