Two PRs from dev, both verified on staging.

#88  a new SKU's first staged release reaches in-bucket devices
#89  new releases register at 0% and a 0% row never displaces a rollout in progress
 sync registers a new stable version
-  → row @10%, 10% of devices update on their next check
+  → row @0%, nobody updates until an operator raises it

 Retrieve(deviceId, sku)
-  latest   = newest version
+  latest   = newest version with percentage > 0
   fallback = newest version at 100%, or null when none ships this SKU

Staging, with 0.5.3 @50 and 0.5.4 @0:

bucket 8   → 0.5.3     (old code: 0.5.2)
bucket 95  → 0.5.2

Compare script against production before the staging rows were changed: 216 cases, 216 pass.

Operator change

A new release is now invisible until its rollout is raised. The next mini or v2 release: register (tick or workflow), check the row, set the percentage.

No migration.


Note

Medium Risk
Changes device OTA version selection and default rollout behavior for all stable update checks; misconfiguration could delay or mis-route firmware until operators adjust percentages.

Overview
New releases stay dark until an operator raises rollout. Sync now registers stable versions at 0% instead of 10%, so devices do not pick up a build on the next check until rollout is increased manually.

Retrieve rollout logic is tightened. The “latest” candidate ignores rows at 0%, so registering a newer version no longer interrupts an in-progress staged rollout. The 100% fallback only considers releases that actually ship a binary for the requested SKU; when none qualify it returns null (same as “nothing fully rolled out for this SKU”) instead of erroring, which lets first staged builds for a new SKU reach in-bucket devices even when older 100% rows lack that SKU’s artifact.

Tests cover 0% sync defaults, mid-rollout stability when a newer 0% row exists, and staged SDMMC releases.

…78)

A prefix with no release at 100% made the default lookup throw a 500
before eligibility was checked, so no device got the staged build. That
is every device for a new prefix until its first release is fully
rolled out, and every JetKVM device the day no app or system row sits
at 100%.

The default lookup now returns null when nothing is at 100%. A device
inside the rollout bucket gets the staged release as before; a device
outside it gets a 404 saying no release is rolled out yet for its SKU,
instead of a 500.

Found by Bugbot on the release PR (#77).
* feat(releases): sync new R2 releases from the API every 30 minutes

The release sync only ran when an operator invoked scripts/sync-releases.ts
by hand, so a firmware upload sat in R2 until someone remembered to run it.
The API process now runs the same sync on start and every 30 minutes,
registering each new stable version at the default 10% rollout.

The non-interactive core (bucket listing, artifact collection, DB insert)
moves from the script into src/release-sync.ts so the API can import it;
the script keeps the GPG check and the confirmation prompt and passes them
in as the release decider. Both entry points share one R2 client via src/s3.ts.

Scheduled runs skip a tick while the previous run is still going, log and
survive a failed run, and treat a unique-constraint hit on insert as
"already synced" so several API instances can race without an error.
The existence check now precedes the R2 artifact walk, so a tick over an
already-synced bucket costs one list call per prefix plus one DB lookup per
version.

* fix(release-sync): defer versions whose upload is still settling

A scheduled tick can land while a version is still being uploaded and
register it with a partial SKU set or a hash that changes afterwards. Sync
never rewrites a row, so that snapshot would be permanent.

Before collecting artifacts, list every object under the version folder
and skip the version when the newest object changed in the last 10
minutes. The window is shorter than the schedule interval, so a real
upload costs at most one extra tick.

* refactor(release-sync): share R2 config, paginate via SDK, probe SKUs concurrently

* src/s3.ts now exports bucketName and baseUrl next to the client, so the
  request handlers, the scheduler and the script read R2 config from one
  place instead of three.
* The upload settle window moves into SyncConfig.uploadSettleMs. The
  scheduler sets it; the one-shot operator script leaves it unset because an
  operator sees the artifact list before confirming and has no next run.
* newestUploadTime uses the SDK's paginateListObjectsV2 instead of a
  hand-rolled continuation loop.
* collectReleaseArtifacts probes SKUs concurrently and folds the results in
  SKU order, so artifact order and the primary artifact are unchanged.
* Tests drop empty per-prefix listing stubs that the file-level default
  already covers.

* fix(release-sync): take the settle listing after the artifact scan

Listing the version folder before the scan left a gap: an upload that
started between the listing and the scan passed the check and was captured
partially. Listing after the scan closes it, because any upload active
during the scan leaves an object newer than the window and the snapshot
is discarded instead of registered.

* fix(release-sync): paginate the version listing

ListObjectsV2 returns at most 1,000 common prefixes per page. Once a
release prefix grows past that, versions on later pages were never seen
on any tick. listStableVersions now walks every page with the SDK
paginator, as newestUploadTime already does, and the mock in the sync
tests can serve a truncated listing.

* fix(release-sync): only treat a unique violation as a race when the row exists

Sync caught every P2002 from the release insert as "created concurrently
elsewhere". On staging the id sequences were behind the rows after a data
import, so each insert failed on the primary key, was logged as a race, and
left nothing in the table.

After a unique violation, createRelease now looks the (version, type) row
up. Present means another instance registered it first; absent means the
insert really failed, and the error is rethrown with the type and version
in its message so the scheduled run log names the release.

* fix(release-sync): name the release in every per-version failure

Wrapping only the insert error left the row lookup, and the S3 scan
before it, free to escape without the type and version. syncReleases now
wraps whatever createRelease throws for a version.
The scheduled tick found a new version at most 30 minutes plus the settle
window after upload. The upload script knows when its last object is
written, so it can trigger the sync itself.

One runner now owns the in-progress flag and serves both the timer and
the endpoint. The endpoint is guarded by RELEASE_SYNC_TOKEN as a bearer
token, compared in constant time, and is not registered without it. It
runs with the settle window off and answers with the per-outcome counts,
or 409 while a run is in progress.
Scheme names are case-insensitive (RFC 9110). The token is still
compared exactly.
…#84)

The endpoint turned the settle window off for every version in the
bucket. A call made while a different upload was still running
registered that upload half done, and sync never revisits a row.

The body now names the version the caller finished, and only that
version skips the window. Without a body the call is a normal tick.
getDefaultRelease threw when 100% releases existed for the prefix but
none shipped a binary for the SKU. Retrieve awaits that fallback before
it checks whether the device is in the staged release's bucket, so the
first staged release for a new SKU on a shared prefix answered 404 to
every device of that SKU. It now returns null, like a prefix with no
100% release at all, and the caller's bucket check decides.
* feat(releases): register new releases at 0% rollout

A newly registered release went to 10% of devices at once. It now
starts at 0%: registered, but served to no device until an operator
raises it. Existing rows keep their percentage.

* fix(releases): a 0% release does not displace a rollout in progress

Selection took the single newest release as the rollout candidate, so
registering the next version at 0% pushed every device off an older
release still mid-rollout and onto the last 100% one. The latest lookup
now ignores rows at 0%. Version-constrained requests, which skip
rollout, still see them.
