+# finance_saa memory integration status
+
+Date: 2026-04-24
+Repository: `SocioProphet/memory-mesh`
+
+## Purpose
+
+This document records the current integration state of the `finance_saa` runtime work inside `memory-mesh`, including what is merged, what is tested, what remains unproven, and where the work should integrate next across the wider SocioProphet estate.
+
+## Current merged state
+
+`main` now contains the first memory-backed finance committee vertical slice:
+
+- `memoryd` runtime alignment toward the draft `memory.mesh.v1` contract.
+- `finance_saa` bootstrap runtime.
+- finance artifact persistence into `memoryd`.
+- finance session snapshot persistence.
+- snapshot-backed session recovery from `memoryd`.
+- runtime validation workflow.
+- focused finance source-of-truth test workflow.
+
+## Relevant merged PRs
+
+- PR #6 — draft `memory.mesh.v1` and `finance.saa.v1` contracts plus runtime alignment work.
+- PR #8 — finance source-of-truth remediation, moving finance session recovery toward snapshot-backed memory semantics.
+- PR #9 — runtime validation workflow for `memoryd` and `finance_saa`.
+- PR #10 — focused finance source-of-truth tests and dedicated test workflow.
+
+## Runtime surfaces now present
+
+### `memoryd`
+
+`memoryd` now exposes and/or supports the runtime semantics needed by the current bootstrap slice:
+
+- scoped `ScopeEnvelope` context
+- compiled workload configuration
+- `config_hash` support
+- local memory write IDs
+- typed memory events
+- workload/workspace-aware recall filtering
+- policy-gated raw event and relation recall access
+
+### `finance_saa`
+
+`finance_saa` currently provides an HTTP/FastAPI bootstrap service for:
+
+- session start
+- assumptions submit
+- proposal submit
+- proposal critique
+- risk check
+- vote record
+- decision select
+
+The service persists finance artifacts to `memoryd` and now persists `session_snapshot` artifacts after state mutations. On session lookup, it prefers snapshot-backed recovery from `memoryd` when `FINANCE_SAA_MEMORYD_SOURCE_OF_TRUTH=true`.
+
+## Validation surfaces now present
+
+### Runtime validation
+
+Workflow: `.github/workflows/validate-runtime.yml`
+
+Covers:
+
+- dependency installation for `memoryd` and `finance_saa`
+- Python module compilation for runtime services and scripts
+- upstream lock validation
+- deploy asset validation
+
+### Finance source-of-truth tests
+
+Workflow: `.github/workflows/test-finance-source-of-truth.yml`
+
+Covers:
+
+- snapshot round-trip via `build_session_snapshot()` and `hydrate_snapshot()`
+- session recovery from a `memoryd` snapshot
+- fallback to local cache when memory is disabled
+- memory receipt recording when persisting artifacts
+
+## Known limitations
+
+1. **No confirmed workflow result captured here.** The workflows are present on `main`, but a pass/fail status has not yet been recorded in this status document.
+2. **HTTP-first bootstrap remains.** `finance_saa` and `memoryd` are still HTTP/FastAPI surfaces, not TriTRPC-native services.
+3. **Snapshot recovery is not full replay.** `finance_saa` recovers session state from snapshots, not from a deterministic event-sourced replay stream.
+4. **Typed artifact API is incomplete.** Finance artifacts are still persisted through memory write semantics, not through first-class `Artifact.Write`, `Artifact.Latest`, or `Artifact.ReplaySession` APIs.
+5. **Policy is not yet externalized.** Decision gating is still local runtime behavior rather than compiled policy from `policy-fabric`.
+6. **Ontology semantics are not yet integrated.** Finance artifacts do not yet have RDF/OWL/JSON-LD classes and SHACL gates in `ontogenesis`.
+7. **AgentPlane evidence is not yet wired.** Finance sessions do not yet emit AgentPlane `ValidationArtifact`, `RunArtifact`, `ReplayArtifact`, or promotion/reversal artifacts.
+8. **Platform deployment is not yet wired.** `prophet-platform` does not yet carry the deployment profile, platform contract, or eval-fabric receipt surface for this capability.
+
+## Cross-repo ownership map
+
+| Concern | Owning repo | Current status |
+|---|---|---|
+| Memory substrate and bootstrap finance slice | `SocioProphet/memory-mesh` | Active, merged vertical slice |
+| Deterministic RPC and fixtures | `SocioProphet/TriTRPC` | Not yet integrated for this capability |
+| Runtime/deployment hub | `SocioProphet/prophet-platform` | Not yet wired |
+| Execution/evidence/replay | `SocioProphet/agentplane` | Not yet wired |
+| Policy-as-code gates | `SocioProphet/policy-fabric` | Not yet wired |
+| Ontology/SHACL semantics | `SocioProphet/ontogenesis` | Not yet wired |
+| Human/approval/promotion-adjacent intelligence surface | `SocioProphet/human-digital-twin` | Pattern exists; not yet integrated |
+
+## Recommended next implementation phase
+
+Phase 1 should harden `memoryd` as a typed artifact substrate:
+
+- add `Artifact.Write`
+- add `Artifact.Get`
+- add `Artifact.List`
+- add `Artifact.Latest`
+- add `Artifact.ReplaySession`
+- add idempotency keys
+- add parent artifact hashes
+- add monotonic sequence numbers per session
+- add tests for deterministic latest-snapshot selection and stale-snapshot rejection
+
+## Completion definition for Phase 1
+
+Phase 1 is complete when `finance_saa` no longer recovers snapshots via free-text recall and instead uses typed artifact APIs for deterministic session reconstruction.
+
+## Follow-on phases
+
+1. Add typed artifact APIs in `memoryd` and migrate `finance_saa` onto them.
+2. Add `memory.mesh.v1` and `finance.saa.v1` TriTRPC contract fixtures.
+3. Add platform-facing service/deployment contracts in `prophet-platform`.
+4. Add ontology modules and SHACL gates in `ontogenesis`.
+5. Add policy examples and compiled decision gates in `policy-fabric`.
+6. Add AgentPlane bundle/evidence/replay integration.
+7. Add estate-level ADR documenting ownership boundaries and integration flow.
