Repin bifrost 0.7.0→0.8.0 and reimplement the memory store's search scope
filter to the v0.6 split (#11): scope_all (AND/intersection) + scope_any
(OR/union over a list of conjunctive scopes), at parity with the v0.6
reference _matches_scope / _validate_scope. No-compat: scope_filter removed.
scope_any is the union-visibility primitive that resolves the #295/#297
silent-zero AND foot-gun — a subset-scoped chunk now recalls via an OR
member. End-to-end cold recall now gated only on Worldtree emitting
scope_any on its recall path (#297, upstream).
- store: search(scope_all, scope_any); _scope_subset + _matches_scope + _validate_scope
- contract v1.2: search FN sig, INV-005 recomposed, PRE-003 both fields, scope_any_union test
- tests: scope_any union, scope_all∧scope_any compose, both-empty match-all; parity vs real 0.8.0 dispatch (433 green)
- #17 contract: sync stale scope_filter/_scope_matches-AND refs to scope_all/scope_any
- runbook + persistent-memory updated; provider bounced onto 0.8.0 (fresh empty db)
v0.17.6
bifrost 0.7.0 (wire v0.5) makes agent_self canonical: the scope lattice is
now {end_user, group, tenant, agent_self}. Our store was MORE permissive than
bifrost's reference (no _validate_scope_filter), which silently 0-zeroed the
#295 cold recall instead of a loud 400. Now matched: search rejects an
out-of-lattice axis with InvalidFilter (-> memory.invalid_filter 400), agent_self
admitted. Purely additive — everything that validated before still validates.
Closes the parity gap our own foot-gun flag opened (bifrost-dev shipped the
lattice add #10 off it). Pin bumped bifrost>=0.6.1 -> >=0.7.0. Contract
search PRE-003 + lattice_axes test; 2 new store tests; full suite 429 green.
The 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)
green; ruff clean. Deps: +sqlite-vec.
