- #368 (user,character) memory silo test DONE + PASSED live (WT b127): write-side conjunctive {end_user,agent_self} scoping + read-side cross- character isolation both proven end-to-end; betty (throwaway) deleted, Sindra intact. Full record in persistent-memory.d/2026-07-18-368-silo- test-passed.md. Retired the stale "silo test in progress" in-flight blocks. - Two-tier migration: split 152 over-threshold dated entries into persistent-memory.d/ detail files, leaving one-line pointers in the index (startup load ~196KB -> ~53KB; bodies now load on demand). - Tier-3 stores scrubbed clean (memory 0 / affect 0, provider restarted empty); persistent-memory + detail file updated to reflect the scrub.

[2026-07-01] Embedding-latency loop RESOLVED — it was WORLDTREE's, not ratatoskr (the consumer/provider thesis paid off again). Vuong flagged dozens of embed queries/Tier-3 turn; worldtree-dev's first-pass blamed our memory_context chunk-batching. Traced CODE-SIDE that ratatoskr embeds ZERO times (provider upsert_many stores the given embedding, search takes a given vector, the conversation consumer POSTs only {content}, /embed is coverage-map-excluded — pure Bifrost/ADR-0009 path, WT does all embedding). worldtree-dev retracted + fixed on THEIR side (v1.0.0b4): a persona-recitation memory-gate re-embedding the stable character card sentence-by-sentence every turn (~95% of gateway traffic) → content-hash cache; re-embed ratio 15x→1.01x. Lesson: verify your own code before accepting a peer's "it's your side" — the debug tool proving its own side clean is the whole point.
