- #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.
