/**
 * ACCEPTANCE TEST for #3671: org-published LLM providers never finish syncing
 * to member desktops — the settings row sits on "Syncing" forever (suspect:
 * commit 316d364d0's engine-reload guard deferring reloads indefinitely).
 *
 * EXPECTED RED on dev as of 2026-08-11, at claim 1 or claim 2. Every failure
 * message embeds the per-provider /cloud-provider-sync/status payload so a red
 * run discriminates the three failure modes on its own:
 *   - stuck-syncing            -> claim 1 times out; the payload shows which
 *                                 provider never reached a terminal outcome.
 *   - applied-but-engine-empty -> claim 1 green, claim 2 red; status lists the
 *                                 provider (fingerprint recorded as done) but
 *                                 the engine never served its model — the
 *                                 settings row derives "Syncing" from exactly
 *                                 this gap (entitled && !available).
 *   - silent-skip              -> a published provider is absent from status
 *                                 with no failure message anywhere (claims 1/3).
 *
 * Terminal per-provider outcome, derived from the real schema
 * (apps/server/src/cloud-provider-sync.ts:33-69): CloudProviderSyncStatus has
 * hasSession, lastRun { at, status: "applied"|"noop"|"failed", message?,
 * detail? } and providers[] (CloudProviderSyncStatusProvider: cloudProviderId,
 * providerId, sourceProviderId, name, source, updatedAt, modelIds, importedAt).
 * A provider entry only materializes after a successful pass
 * (updateProviderStatus, cloud-provider-sync.ts:781-801), so "terminal" here
 * means: the provider's cloudProviderId is listed AND lastRun settled as
 * applied|noop. Repeated "failed" (or absence) is permanently non-terminal.
