📝 WalkthroughWalkthroughThe migration adds ChangesOTA version locking
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The change prevents linked r2-direct bundles from having delivery-critical metadata rewritten, while preserving finalization for unlinked uploads. The PR is mergeable with owner awareness: the new lookup should be profiled for update-time overhead, and one metadata-update test should be corrected so it verifies a real change.

check_encrypted_bundle_on_insert(), including expected workload, executing role,
table/index cardinality, and a worst-case EXPLAIN (ANALYZE, BUFFERS) result
covering both version and rollout_version predicates. Keep the existing lookup
behavior unchanged and add the profile documentation in the migration.

- Around line 184-192: Update the test setup and assertion around the
app_versions metadata update so comment is initialized to one value during
insertion, then change comment to a different value in the final UPDATE. Keep
the existing app_id, version name, and lives_ok coverage unchanged while
ensuring the UPDATE performs a real metadata change.

OTA-selectable r2-direct rows stayed mutable because the content-lock trigger treated storage_provider = r2-direct as not ready. Upload keys could then change checksum/session_key on a channel-linked bundle via PostgREST (GHSA-5rg9-rhwj-wj76). Unlinked in-progress uploads can still finalize r2-direct to r2.
Full content-lock on channel-linked r2-direct broke CLI finalize metadata writes (native_packages). Deny only checksum/session_key/key_id while the row is still r2-direct and OTA-selectable.

Summary (AI generated)
app_versionsfields (checksum, session_key, and the rest of the existing content-lock set) when a version is channel-linked viachannels.versionorchannels.rollout_version, even ifstorage_provideris stillr2-direct.r2-directuploads can still finalize tor2.r2-directrow through PostgREST because the trigger treatedr2-directas not ready.Motivation (AI generated)
/updatesalready serves channel-linkedr2-directversions (deleted = falseonly). The content-lock trigger exempted those rows, so a caller with upload rights could rewrite checksum or session_key on a live OTA target without uploading a new bundle.Business Impact (AI generated)
Stops a content-integrity bypass on live OTA channels. Devices keep receiving the checksum and encryption material that were set when the bundle was linked, instead of a later PostgREST rewrite.
