Logging these as errors is causing monitoring noise. Warning is more consistent with other "out of sync" scenarios.
…hannel The webhook provider disables an endpoint on its own after a prolonged delivery failure and never pushes that decision back, so the channel kept reporting itself as enabled while every event through it failed immediately. The reconciler already reads the provider-side flag; write it back onto the channel with an annotation recording when the disable was observed. Re-enabling stays a user action through the regular channel update path, which also re-enables the endpoint at the provider.
Exercise disableChannelForProvider and its reconciler call site against a PostgreSQL-backed repository, faking the provider by embedding the no-op webhook handler so no live Svix server is needed. Covers the delivery status failing alongside the channel disable, the annotation merge preserving existing annotations, and the early return on an already-disabled channel.
Reconciliation now mirrors a Svix-side endpoint disable onto the channel, so the claim that a failed delivery never disables its channel no longer held. Qualify that bullet and describe the write-back, the annotation marking it, and the user-driven re-enable path.

- Around line 199-221: The reconciliation flow around ReconcileWebhookEvent and
disableChannelForProvider must reject stale provider observations: capture the
channel revision before ListWebhooks, pass it through reconciliation, and
require that revision alongside channeldb.Disabled(false) in DisableChannel’s
conditional update. Advance the revision in UpdateChannel, and treat a no-row
conditional update as a stale observation without disabling the channel.
In `@openmeter/notification/channel.go`:
- Line 282: Update disableChannelForProvider and the
DisableChannelInput/adapter.DisableChannel flow to preserve concurrent
annotation updates: carry the observed annotations or version into the disable
request, condition the write on that observation, and retry conflicts;
alternatively, atomically merge only the provider-disabled timestamp instead of
replacing the full annotation map.

Mirroring a provider-initiated disable through UpdateChannel rewrote every mutable field from a snapshot read moments earlier, so a channel update racing with reconciliation was silently reverted. Add DisableChannel, a single conditional statement that sets only the disabled flag and the annotations and matches only a channel that is still enabled.

Overview
What
Reconciliation now mirrors a provider-side endpoint disable onto the notification channel, stamping a
channel.provider.disabled.timestampannotation so the reason is visible.Why
Svix disables a webhook endpoint on its own after a prolonged delivery failure (
endpoint_failure_disable_after, 120 hours by default) and never pushes that decision back to us. OpenMeter's channel row kept reportingdisabled: false, so every matching event still fanned out a delivery status that immediately failed withErrSystemChannelDisabled— one warning line per event, per channel, indefinitely.This also makes the preceding log-level downgrade (error -> warn) correct rather than merely quieter. Verified against the Svix server source that sending to a disabled endpoint costs nothing:
filtered_endpointsdrops disabled endpoints before any attempt is scheduled, so there is no HTTP call, no retry backlog, and no penalty.How
The reconciler already read the provider-side flag in order to fail the delivery status; it just threw the fact away. It now writes that state back onto the channel as well. Re-enabling stays a user action through the regular channel update path, which also re-enables the endpoint at the provider.
Fixes OM-206.
Notes for reviewer
ListWebhookscall per namespace every 15 seconds, and nothing re-enables an endpoint on the Svix side, since Svix is not user-facing.service/channel.gopushesDisabled: channel.Disabledon every channel update, so editing a channel re-enables a provider-disabled endpoint. That is now the intended re-enable path, but it means an unrelated edit also clears the marker.webhook_test.goconstructs a lock client that is never exercised — the tests callreconcileWebhookEventanddisableChannelForProviderdirectly, bypassing the leader lock, whileConfig.Validate()still requires it non-nil.Verification
