feat(provider): memory plane — SQLite+sqlite-vec store + dev shell
vh released this
2026-06-15 21:39:42 -07:00 | 219 commits to main since this releaseThe second plane of ratatoskr's Tier-3 Bifrost consumer: a durable memory
store Worldtree writes agent memory chunks into (upsert_many) and recalls
by vector similarity (search), with point reads + deletes. Implements
bifrost's own MemoryDataStore Protocol; conformance is #195 parity vs
InMemoryMemoryStore through the real dispatch_memory_call.Store (memory_store.py): open_memory_store, describe_store, upsert_many
(replay/conflict idempotency, optimistic locking, injection rule, atomic
batch), search (cosine over sqlite-vec vec0, scope isolation INV-005,
over-fetch-then-filter so top_k counts in-scope), get/get_many,
delete_many, build_memory_provider_app. Dev shell (serve_memory.py):
ratatoskr-memory-provider entrypoint, port 8391.TDD + heid-code-review (panel Groa/Hulda/Regin, zero true drift). Adopted
fixups: scope_filter dict guard, top_k<=0 -> [], stronger scope-isolation- delete-hit-search + handshake-POST tests. Partial-map optimistic-lock
semantics pinned against the reference via a new expected_revisions
parity test.
26 memory + 4 serve tests; #195 parity (upsert/search/expected_revisions)
