bifrost 0.10.0's _supports_affect_plane (bifrost/affect.py:75-80) now requires a
callable fetch for the affect capability to advertise/dispatch at all (INV-012
strong-or-absent), so an emit-only store 400s on EVERY affect op — repinning past
the affect.fetch release (#12/#13) breaks our shipped affect plane until fetch
exists. Implement affect.fetch as a thin async wrapper over the existing get()
read seam, conformed verbatim to the reference InMemoryAffectStore.fetch:
{"found": False} or {"found": True, "snapshot": <verbatim>}, AffectInvalidArguments
on empty ids, opaque (INV-001 — never reads pad/valence).
This is the forced prerequisite for the #18 D1 composite (build_combined_app),
and a new Worldtree I/O point consumed (affect read-back over bifrost).
- Repin bifrost>=0.8.0 -> >=0.10.0 (uv lock: 0.8.0 -> 0.10.0)
- affect_store.py: add async fetch() over get()
- contract bifrost_affect_provider v1.2: fetch FN block + INV-010 (cap = supported+emit+fetch)
- tests: 3 fetch unit + parity_vs_reference_fetch through dispatch_affect_call
- suite 482 -> 486 green
The first slice of ratatoskr-as-Tier-3-Bifrost-consumer: a SQLite-backed,
conduit-opaque affect store Worldtree emits Tier-3 persona/affect snapshots
into, plus the thin build_affect_provider_app wiring. The bifrost library
owns the wire; this owns only the store + glue.
- ratatoskr.provider.affect_store: open_affect_store / emit / get /
build_affect_provider_app. Two-table SQLite schema (snapshots + idempotency).
- Conduit-opaque (INV-001): reads only the two addressing keys; whole-blob
hash only. LWW-by-arrival across distinct keys; replay-or-conflict
idempotency (actor-scoped from ctx), raising bifrost's typed exceptions.
- Conformance: #195 parity vs InMemoryAffectStore through the real
dispatch_affect_call engine. 17 provider tests; 395 full suite.
- Contract v1.1: idempotency model corrected to bifrost's actual semantics
(caught by real-lib TDD; the artifact-only review structurally could not).
Heid-panel reviewed (contract + code); idempotency-cache TTL pruning,
memory.* plane, and the combined two-plane server deferred (see Out of scope).
