Signal layer telemetry.
Runtime view of the live aggregation system behind toddwatts.dev: source health, coverage, latency, ranking policy, API contract posture, snapshot posture, and publishing configuration.
Ranked source fabric.
source-weighted score with recency decay and source diversity caps
prefer source diversity until 36 selected items, then allow up to 6 per source
History writer is available but disabled. Set OPS_HISTORY_PROVIDER=vercel-blob with BLOB_READ_WRITE_TOKEN for durable production history.
no BLOB_READ_WRITE_TOKEN and local history writes are disabled
MONITOR_ALERT_WEBHOOK_URL is missing in production
OpenAPI 3.1 documents 8 API paths and 46 schemas. Local release gates fetch `/api/openapi` before exercising the live route handlers.

Operator recommendations prioritize failed fetches, stale inputs, slow sources, and low-selection signal before any source-weight changes are made.
Source fetcher failed during the current aggregation run.
Inspect the upstream URL, parser contract, and timeout behavior before trusting this source in the ranker.

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.
Every input, visible.
Category mix and history.
No local snapshots yet. This is expected unless FEED_SNAPSHOT_WRITE=1 is configured.
Provider is disabled; durable storage needs Vercel Blob credentials.
Blog publishing is guarded by bearer auth, schema validation, CORS allow-listing, rate limiting, and attempt history.
Set MONITOR_ALERT_WEBHOOK_URL to route degraded/error monitor runs to Slack, email automation, or incident tooling.
`/api/openapi` publishes 8 documented paths, 46 schemas, and bearer-auth schemes for publish and monitor operations.
