# Verification Report: cerebro-memory-enhancement-layer

## Verdict

**PASS WITH WARNINGS**

Previously blocking verification failures have been resolved. The change now has clean focused execution evidence for the repaired runtime discovery path, the repaired dashboard composable delete flow, the gateway Cerebro surface, and the targeted dashboard Cerebro UI slice. Remaining gaps are non-critical and mostly about breadth of behavioral coverage and docs completeness rather than current correctness regressions.

## Acceptance Criteria Traceability

| Proposal acceptance criterion | Status | Exact evidence |
|---|---|---|
| Gateway exposes an admin-only Cerebro capability/status API that distinguishes configuration, reachability, and per-tool readiness | **PASS** | `gateway/mod.rs` registers `/web/admin/cerebro/status`; `gateway/cerebro.rs` defines typed status contract; `cargo test ... gateway::cerebro::tests` passed and includes unconfigured + mixed available/not_implemented coverage |
| Gateway exposes typed proxy endpoints for approved Cerebro memory workflows without allowing arbitrary MCP passthrough | **PASS** | typed routes exist for search, observation, timeline, stats, memories, prompts, sessions, context; raw MCP rejection test passed in gateway suite |
| Dashboard memory views support Cerebro semantic search and drill-in when Cerebro is available | **PASS** | `CerebroSearchPanel.spec.ts`, `CerebroObservationDetail.spec.ts`, and `CerebroTimelinePanel.spec.ts` passed; `App.vue` wires search + observation + timeline components |
| Dashboard surfaces remote stats, observation detail, and timeline/history insights from Cerebro without regressing existing local memory visibility | **PASS** | `MemoryStats.spec.ts` passed for separate local/remote stats and unreachable fallback; `CerebroObservationDetail.spec.ts` and `CerebroTimelinePanel.spec.ts` passed; local browser remains intact in `MemoryList.vue` |
| Dashboard session detail exposes Cerebro session/context actions or status for `mem_session_start`, `mem_session_end`, `mem_session_summary`, and `mem_context` | **PASS** | `SessionDetail.spec.ts` and `CerebroSessionActions.spec.ts` both passed; gateway status test now asserts `mem_context` is `available`; `normalize.rs` no longer treats `mem_context` as a planned tool |
| When a planned tool returns `NotImplemented`, gateway and dashboard surface a normalized understandable state | **PASS** | `session_summary_normalizes_not_implemented` passed in gateway suite; `CerebroSessionActions.spec.ts` passed with explicit `not_implemented` rendering |
| Non-Cerebro deployments continue working unchanged with existing local session/memory views | **PASS WITH WARNINGS** | gateway suite covers unconfigured/unreachable responses; `MemoryStats.spec.ts` and `MemoryList.spec.ts` passed; local-first structure preserved in `MemoryList.vue` and `SessionDetail.vue`; still no direct runtime test for local session detail during Cerebro outage |
| All new Cerebro proxy routes require existing admin auth and do not leak Cerebro auth tokens, raw MCP payloads, or sensitive memory data outside intended responses | **PASS** | admin auth test passed in gateway suite; raw MCP passthrough rejection test passed; `tools::mcp::client::tests::list_tools_redacts_auth_token_from_failures` now passes |
| Runtime and dashboard tests cover success, unavailable, unreachable, and not-implemented states for the enhancement layer | **PASS WITH WARNINGS** | clean passing focused test runs now exist across runtime + dashboard; however scenario coverage is still not exhaustive for older-backend `unsupported` and end-user exclusion |

## Spec Scenario Compliance Summary

### Executed passing evidence
- `memory-visibility`: status reports an unconfigured deployment
- `memory-visibility`: status reports mixed ready and planned tools
- `memory-visibility`: typed semantic search succeeds without raw MCP passthrough
- `memory-visibility`: raw tool passthrough is rejected
- `memory-visibility`: planned session summary returns normalized `not_implemented`
- `memory-visibility`: reachability failures return normalized `unreachable`
- `memory-visibility`: Cerebro status response matches typed contract
- `client-surfaces`: admin performs Cerebro semantic search
- `client-surfaces`: dashboard shows local and remote stats separately
- `client-surfaces`: remote stats outage does not hide local stats
- `client-surfaces`: session detail shows planned Cerebro tools explicitly
- `client-surfaces`: session detail invokes available context lookup (dashboard-side mocked/runtime-backed UI proof via `CerebroSessionActions.spec.ts`; gateway capability state now also supports `available`)
- `client-surfaces`: session detail separates local facts from Cerebro enhancements
- `client-surfaces`: dashboard distinguishes configured from truly available Cerebro
- `client-surfaces`: dashboard types support normalized Cerebro states
- `client-surfaces`: admin drills into a Cerebro result
- `client-surfaces`: dashboard renders relationship insights only when present

### Static evidence present, but no direct dedicated passing test mapped yet
- `memory-visibility`: status reports a reachable but older backend (`mem_timeline` => `unsupported`)
- `memory-visibility`: local memory visibility still works without Cerebro
- `memory-visibility`: local session detail remains authoritative during Cerebro outage
- `memory-visibility`: end-user routes do not expose Cerebro capability data
- `client-surfaces`: dashboard shows Cerebro as unavailable without blocking local tools
- `client-surfaces`: dashboard enables Cerebro features only when available
- `client-surfaces`: admin switches between Local Memory and Cerebro Memory modes
- `client-surfaces`: unreachable Cerebro does not regress local session views
- `client-surfaces`: end-user surfaces cannot access Cerebro operator features

## Static Correctness / Design Coherence

### Confirmed improvements since prior report
- `normalize.rs` now tracks only 4 planned tools; `mem_context` is no longer hardcoded as planned.
- `gateway/cerebro.rs` test now verifies `mem_context` reports `available` in the available/planned status mix.
- `client.rs` live discovery tests now run on a multi-threaded Tokio runtime and pass.
- `useAdmin.ts` `fetchJson()` now safely handles `204` and empty response bodies, which resolves the prior delete-path test failure.

### Design alignment
- Dedicated gateway Cerebro module remains in place.
- Typed REST wrappers remain in place; no raw JSON-RPC passthrough was introduced.
- Local Memory and Cerebro Memory remain parallel, clearly segmented views.
- Live HTTP `tools/list` discovery is now both implemented and verified.

## Issues Found

### CRITICAL
- None.

### WARNING
- Docs are still not updated to describe the operator-facing gateway/dashboard Cerebro capability semantics (`clients/web/apps/docs/src/content/docs/cerebro/mcp-tools.md` remains focused on raw MCP inventory).
- Some delta-spec scenarios still lack direct executed proof, especially older-backend `unsupported`, end-user exclusion, and observation/timeline/relationship rendering specifics.
- Dashboard-focused tests still emit missing-i18n warnings; not a blocker for this verify phase, but noisy.

### SUGGESTION
- Add a focused gateway test for the older-backend `unsupported` status path.
- Add one explicit end-user/non-admin regression test proving Cerebro admin capability data does not appear on non-admin routes.

## Rollback Strategy

### Threat / risk notes

- Gateway and runtime changes touch an admin-only surface in `clients/agent-runtime/src/gateway/cerebro.rs`, so rollback must preserve auth/origin boundaries first.
- Normalization changes in `clients/agent-runtime/src/tools/mcp/normalize.rs` affect how degraded Cerebro states are surfaced; rollback should watch for false-positive `unreachable` classification or accidental raw error leakage.
- Client fetch behavior in `clients/web/apps/dashboard/src/composables/useAdmin.ts` now sets JSON headers and validates session-scoped actions earlier; rollback must avoid reintroducing malformed admin requests.

### Ordered rollback runbook

1. Notify the gateway/runtime on-call owner and dashboard owner that Cerebro enhancement rollback is starting.
2. Revert the Cerebro admin gateway module changes in `clients/agent-runtime/src/gateway/cerebro.rs` and the route wiring that exposes `/web/admin/cerebro/*`.
3. Revert the normalization adjustments in `clients/agent-runtime/src/tools/mcp/normalize.rs` if status mapping or redaction behavior is implicated.
4. Revert the dashboard/admin fetch changes in `clients/web/apps/dashboard/src/composables/useAdmin.ts` and the Cerebro-specific dashboard components if the operator UI is the source of the regression.
5. Redeploy the previous known-good branch/commit and confirm local session and memory pages still work without Cerebro enhancement.

### Smoke tests after rollback

1. Confirm `/web/admin/sessions` and `/web/admin/memory` still return healthy local-only responses.
2. Confirm non-admin or invalid-origin access to Cerebro admin routes remains denied.
3. Run focused component tests for `CerebroObservationDetail.vue` and `CerebroTimelinePanel.vue` (or confirm they are removed/disabled as intended).
4. Re-run the focused `useAdmin.spec.ts` and gateway Cerebro tests to ensure the rollback did not leave mixed contracts behind.

### Monitoring / alerts / cleanup

- Watch gateway error rate and 5xx spikes on Cerebro admin routes for 15-30 minutes after rollback.
- Watch dashboard operator reports for missing local session/memory visibility.
- No DB migration or state cleanup is required; rollback is contract/UI level only.
