 # 2026-06-18: fixed assertLoggingTrace() failure in test-api-integrations (branch fix/post-sync-137-followup): ReloadProvider in server.go did not call RegisterKnownProvider, so the custom provider name was unknown to ParseModelString at request time → request routed to HuggingFace (wildcard key) → failed → logged status="error" under original request-id; companion test patch changes OTEL-metrics and Prometheus strict label assertions in run-observability-local.mjs from requestedModel to modelName (correct after split routing). plugins/logging go test passes; local observability check prints "passed".
 # 2026-06-18: fixed test-plugins semanticcache flake (branch fix/redis-createnamespace-race): TestSemanticCache_AllVectorStores_ParameterFiltering/Redis intermittently failed with "Index already exists" — a TOCTOU race in framework/vectorstore/redis.go CreateNamespace (FT.INFO check then FT.CREATE not atomic; parallel Plugin.Init calls both create the shared BifrostSemanticCachePluginTest index). Fix treats the benign FT.CREATE "Index already exists" error as idempotent success; added TestRedisStore_CreateNamespace_ConcurrentIsIdempotent regression (fails without the fix, passes with). No workflow files changed.
 # 2026-06-19: disabled PR Test Notifier via `gh workflow disable` — upstream bug: it triggers on push to main but its only step runs `gh pr comment ${{ github.event.pull_request.number }}`, which is empty on a push event → "argument required when using the --repo flag", failing the Post Test Instructions job on every push to main. Meaningless on push-to-main (no PR). Can't fix trigger in-file (no workflow scope); disabled via gh like release-cli/npx-publish. State-only change; file stays vanilla.
