+# Political Event Weekly Producer Artifact
+
+`political-event-weekly-v1` is the producer-owned, complete-UTC-ISO-week artifact
+emitted by the RSS source pipeline.
+
+## Fixed contract
+
+- Scheduled execution is Monday `12:15 UTC` and covers the immediately preceding
+  complete Monday–Sunday UTC ISO week.
+- Manual execution must provide matching `period_start` (Monday) and `as_of`
+  (Sunday). No latest-source or wall-clock fallback is allowed for period identity.
+- `generated_at` is the actual UTC build time and is separate from period identity.
+- `GITHUB_RUN_ATTEMPT` must be exactly `1`; a rerun is fail-closed rather than a
+  new version of the same snapshot.
+- Artifact retention is exactly 30 days.
+
+The dedicated artifact contains exactly:
+
+```text
+period_lock.json
+political_events.csv
+political_watchlist.csv
+political_event_weekly.json
+weekly_manifest.json
+```
+
+The manifest binds the first four files by name, byte length and SHA-256. It also
+records CSV headers/row counts, period/as-of/generated-at, producer SHA,
+workflow ref, run id/attempt, source snapshot digest/provenance, and complete
+feed counters. Any partial/failed/stale/missing feed, source mismatch, unsafe
+wire, or readback mismatch prevents dedicated artifact upload.
+
+This contract is producer-side only. QAR consumer acquisition/readback is a
+separate later slice; no legacy compatibility, identity store, Pages, publisher,
+or workflow permission expansion is implied.
