Ranking policy

source-weighted score with recency decay and source diversity caps

Diversity policy

prefer source diversity until 36 selected items, then allow up to 6 per source

Snapshot policy

History writer is available but disabled. Set OPS_HISTORY_PROVIDER=vercel-blob with BLOB_READ_WRITE_TOKEN for durable production history.

History provider

no BLOB_READ_WRITE_TOKEN and local history writes are disabled

Alert routing

MONITOR_ALERT_WEBHOOK_URL is missing in production

Interface contract

OpenAPI 3.1 documents 8 API paths and 46 schemas. Local release gates fetch `/api/openapi` before exercising the live route handlers.

Source tuning queue6 recommendations

Operator recommendations prioritize failed fetches, stale inputs, slow sources, and low-selection signal before any source-weight changes are made.

No retained feed snapshot is available for comparison yet.

Enable OPS_HISTORY_WRITE=1 locally or Vercel Blob in production to build a tuning window.

The current run is still analyzed so low-quality sources remain visible.

No local snapshots yet. This is expected unless FEED_SNAPSHOT_WRITE=1 is configured.

History store
disabled

Provider is disabled; durable storage needs Vercel Blob credentials.

Publish posture
locked

Blog publishing is guarded by bearer auth, schema validation, CORS allow-listing, rate limiting, and attempt history.

Alert routing
disabled

Set MONITOR_ALERT_WEBHOOK_URL to route degraded/error monitor runs to Slack, email automation, or incident tooling.

API contract
OpenAPI 3.1

`/api/openapi` publishes 8 documented paths, 46 schemas, and bearer-auth schemes for publish and monitor operations.
