 only in our store = channel 2 is just the feedback loop + agent-axis hardening. Post-scrub our #368 backfill is
 a NO-OP (born-conjunctive once the fix ships); contract keeps migration machinery for other consumers. DO NOT
 re-ask Lofn the name meanwhile (re-seeds the loop). Awaiting WT infra-ops server-side-scrub confirm to run it.
+**RAN 2026-07-18 (both scrubs confirmed clean):** marker repro executed — fresh Sindra session 822c3af7
+(combined :8392), user introduced "my favorite mineral is rhodochrosite", 5 more turns drove the idle-scan
+promotion at ~6 turns. RESULT: marker promoted to OUR store scoped **{end_user}-only** (chunk 647aeac6;
+record.agent_id "ratatoskr:sindra" metadata; worldtree_scope "end_user"; verbatim "Favorite mineral is
+rhodochrosite") = **channel-1 baseline exhibit** (pre-fix shape; agent_self absent, to be backfilled from the
+agent_id metadata). **KEY WT CORRECTION:** consumer-defined agents (ratatoskr:sindra) have NO server-side
+chroma — they write ONLY to our store via Bifrost; only FOUNDATIONAL agents (lofn/forseti/mimir) get
+server-side collections. Confirmed on the wire: Sindra IS Bifrost-attached (queried us scan+search) UNLIKE
+foundational Lofn (handshake-only, no memory-call). DECISIVE channel-2 grep (marker must be in ZERO
+server-side stores; ANY server-side hit = cross-plane bug, no benign reading) still PENDING infra-ops.
+**ETA (WT): rev 1.2 amended contract reaches us TODAY 2026-07-18 for the consumer-side enforcement read;
+ship-ready LIKELY 2026-07-19; our integration risk LOW** (born-fresh store won't exercise the backfill
+machinery, which is the bulk of the impl). ratatoskr is the enforcement half; INV-368-9 blocks WT preflight.
