📝 WalkthroughWalkthroughThe PR adds five channel update package modes. It stores the selected mode in the database, exposes it through APIs, adds CLI and UI controls, validates bundle compatibility, and changes update responses to return ZIP bundles or delta manifests according to the channel setting. ChangesChannel update package configuration
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This change adds configurable ZIP and delta delivery, but some delta-only channels can still leave devices without a usable update or report no bundle even when a ZIP exists. The settings screen also may not preserve the selected mode for all users, and one test can become order-dependent, so merge should be blocked pending fixes or explicit owner acceptance.

In `@messages/en.json`:
- Around line 2426-2432: Clarify the update-package-help translation by
explicitly restating that the zip-or-delta choice applies only when devices
remain on the store builtin version, replacing the ambiguous “that rule” wording
while preserving the existing options and meaning.
In `@src/components/tables/ChannelHistoryTable.vue`:
- Line 73: Update formatValue() to handle field === 'update_package' before its
String(value) fallback, mapping package-mode values through the existing
localized update-package-* keys so history displays labels instead of raw
values.
In `@src/pages/app/`[app].channel.[channel].vue:
- Around line 1362-1367: Replace the package-mode option anchors in the
update-package list with button elements using type="button", preserving the
existing styling, click handler onSelectUpdatePackage, and label rendering via
getUpdatePackageLabel.
- Around line 809-810: Add update_package to the channel refresh query’s select
list used by getChannel so saveChannelChange('update_package', value) preserves
the refreshed channel.update_package value and the dropdown reflects the
selected package.
In `@supabase/functions/_backend/plugin_runtime/utils/update.ts`:
- Around line 622-623: Update the deferred manifest logic around
needsDeferredManifest so delta delivery always loads manifest entries,
regardless of version.external_url. Ensure the subsequent delta-channel manifest
construction uses those entries independently of the external ZIP URL,
preserving no_bundle_url only when no manifest-backed bundle is available.
- Around line 571-576: Update the serveZip/serveDelta decision in the update
response flow to force ZIP delivery when the plugin version lacks manifest
support, using the existing plugin-version detection and resToVersion manifest
availability. Preserve the current channel-based package selection for
manifest-capable plugins and keep the response fields and fallback behavior
unchanged otherwise.
In `@tests/updates-manifest.test.ts`:
- Line 128: Update the Supabase channel reset query in the test teardown to call
throwOnError() after the existing filters, ensuring teardown fails when the
update cannot be applied.
Apply the same fix in `@tests/channel.test.ts` around lines 84 - 106: Covers the
shared production-channel mutation that can leak package mode across parallel
tests.

cli/src/bundle/upload.ts, eager evaluation of the fallback template meansformatFunctionInvokeError(error)runs even whenchannelUpdatePackageCliErroralready provides the thrown zip/delta mismatch message, which can add avoidable overhead (and any formatter side effects) on every error path—make the fallback lazy so formatting only happens when that branch is actually used.

P3: The fallback template is now evaluated eagerly, so `formatFunctionInvokeError(error)` runs on every error even when `channelUpdatePackageCliError` has already produced the zip/delta mismatch message that gets thrown. Previously that body re-read (`context.json()`) was skipped when the mismatch message was found. Evaluate the fallback lazily, or keep the two-branch shape, so the unused RBAC message (and its response-body read) is not built on the mismatch path.</violation>

Summary (AI generated)
update_packagesetting so/updatescan serve zip only, delta only, zip only from the store builtin, or delta only from the store builtin--update-package), and channel settings UIMotivation (AI generated)
Some apps want a full zip on first install from the store binary, then deltas after that, or they want to disable one payload type entirely. Today every channel always serves both zip and delta when both exist. Assigning a bundle that cannot serve the chosen package would leave devices with no usable update.
Business Impact (AI generated)
Gives customers control over download size and first-update behavior without a plugin change. Default remains zip + delta, so existing channels keep current behavior. Clear errors tell users to upload the missing zip/delta or switch the channel mode.
