-3. Phase 3 timing: wait for net-kingdom/key-cape agent tokens, and enforce or only observe?
-4. Backfill of legacy authors: map via reviewed file, or leave unmapped?

+1. **Decided:** Option A is phase 1 (claimed tier) with the header names above. No `hub_core`
+   schema change; only the sidecar `write_attribution` table. Revisit `hub_core` if a per-record
+   actor column is ever wanted.
+2. **Decided:** correlation with commits by equal session id and run id only. The asynchronous
+   commit verifier and `commit_ref` (Option B) are deferred; revisit if signed commits are
+   introduced.
+3. **Decided:** phase 3 verifies key-cape agent tokens (KEY-WP-0043) in OBSERVE mode only:
+   record `assurance=token`, never reject. Enforcement is a separate later founder decision.
+4. **Decided:** existing free-text authors are not backfilled. A read-only count of distinct
