Operator ruled: no arbo fork, no SillyTavern-on-Rata; both app products move to
a new repo (template-dev standing up). Rata does NOT fork and reverts to its core
(Worldtree debug surface + Bifrost reference impl + Conversation-API SDK #371
seed/future-consumer). Retires the 2026-07-17 fork-Rata-for-arbo NEXT-MAJOR plan;
resolves the arbo-vs-SDK open question the prior snapshot flagged.
Capture this session's durable state: the "fork Rata for a SillyTavern-style
app?" question resolved to don't-fork — Worldtree owns an official Conversation
API SDK (WT #371), seeded from Rata's client spine; the app is a fresh TS
sibling. New Current-state thread + Recent-decisions entries + a full-arc detail
file; arbo-fork decision preserved with the arbo-vs-SDK priority flagged as an
open operator question. Auto-archived 35 settled 2026-06-14..06-18 entries
(19 Recent, 16 Tried) to archival-memory.md. Handoff refreshed.
Move the consolidated #368 in-flight narrative (diagnosis -> two-channel
investigation -> both scrubs -> marker repro -> enforcement read) out of
persistent-memory.md Current state into the silo-test detail file, leaving
a compact pointer. Index 439 -> 339 lines.
- #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.
