### Build & Tests Execution

**Verification commands from `openspec/config.yaml`**

| Command | Scope | Result | Evidence |
|---|---|---|---|
| `cargo fmt --all -- --check` | `clients/agent-runtime` | ✅ Passed | Previously verified; exit 0 |
| `cargo clippy --all-targets -- -D warnings` | `clients/agent-runtime` | ✅ Passed | Previously verified; exit 0 |
| `cargo test` | `clients/agent-runtime` | ✅ Passed | Updated evidence: fresh full run now passes completely |
| `make web-test-all` | repo root | ✅ Passed | Previously verified; `BUILD SUCCESSFUL` |
| `pnpm --dir clients/web check` | `clients/web` | ✅ Passed | Previously verified; workspace checks completed successfully |

**Additional updated evidence**

- The previously reported failing test `channels::tests::transcription_semaphore_enforces_serial_execution` now passes in isolation.
- A fresh full `cargo test` run in `clients/agent-runtime` now passes completely.
- This removes the prior blocking verification failure from the Rust workspace baseline.

**Build / static quality gates**

- `cargo fmt --all -- --check`: passed.
- `cargo clippy --all-targets -- -D warnings`: passed.

**Tests**

- `cargo test`: ✅ passed on refreshed verification evidence
  - Prior single-test failure is no longer reproducible from the new evidence set.
  - Exact aggregate pass counts were not included in the refreshed evidence bundle, so only overall pass status is recorded here.
- `make web-test-all`: ✅ passed
- `pnpm --dir clients/web check`: ✅ passed

**Coverage**: ➖ Not configured in `openspec/config.yaml`

**Compliance summary**: 10/17 scenarios compliant, 6 partial, 0 failing, 0 untested.

**Remaining partial scenarios**

1. Distilled-memory quality is evidenced, but not by a scenario-named end-to-end assertion that inspects artifact content for a completed session across backends.
2. Transcript-omission is implied by the artifact format and current test behavior, but not asserted directly against a preserved multi-turn transcript fixture.
3. Snapshot coverage restores Dream replay metadata, but the current runtime evidence is lighter on export→hydrate→retrigger end-to-end artifact parity.
4. Restore-time idempotency is indirectly covered by retry/recovery semantics, but not by a dedicated export/shutdown/restore/retrigger scenario.
5. Gateway trigger-only behavior is structurally evident and indirectly exercised, but there is no dedicated test asserting the absence of a new Dream-specific public HTTP contract.
6. Duplicate completion without prior Dream result is partially covered through lock/busy handling rather than an explicit duplicate completion-record retry case.

### Correctness (Static — Structural Evidence)

| Requirement | Status | Notes |
|---|---|---|
| Dream Eligibility for Completed Sessions | ✅ Implemented | `dream_eligibility`, `record_session_completion`, and tests in `memory/dream.rs` enforce completed-session gating and deterministic session-based identity. |
| Dream Consolidation Output Contract | ✅ Implemented | `run_now` writes distilled `Dream summary for completed session {session_id}` entries into `MEMORY.md`, using deterministic artifact refs rather than transcript persistence. |
| Dream Persistence Across Supported Backends | ✅ Implemented | SQLite adds `dream_sessions`; snapshot exports `DREAM_STATE_SNAPSHOT.json`; state sidecar `dream_state.json` is restored on hydrate. |
| Dream Idempotency per Completed Session | ✅ Implemented | Session state machine `pending\|running\|completed\|failed` plus `artifact_ref_for_session` and repeated-trigger suppression are present. |
| Gateway Dream Integration Is Trigger-Only | ✅ Implemented | Gateway finalization path ends session, records completion, then invokes Dream; no gateway-side eligibility logic or Dream-specific persistence logic was found. |
| Gateway Completion Hooks MUST Preserve Runtime Ordering and Idempotency | ✅ Implemented | `finalize_generated_session_if_needed` calls `end_session` before `record_session_completion` before `run_dream_if_triggered`. |
| SESS-5: Stale Session Auto-Close | ✅ Implemented | `close_stale_sessions` updates sessions, then calls `memory::record_session_completion` for each affected stale session. |
| Session Completion Must Produce a Deterministic Dream Trigger Input | ✅ Implemented | Missing completion yields `DreamEligibility::NotCompleted`; recorded completion is the prerequisite for Dream eligibility and trigger evaluation. |
| Session Completion and Dream Triggering Must Be Idempotent Together | ✅ Implemented | Repeated completion recording returns stable session records, and pending/busy/completed behavior preserves one logical Dream outcome. |

### Coherence (Design)

| Decision | Followed? | Notes |
|---|---|---|
| ADR-1: Dream belongs to memory/runtime domain, not gateway | ✅ Yes | Ownership remains in `memory/`; gateway only triggers runtime hooks. |
| ADR-2: Dream is keyed by completed session identity | ✅ Yes | `DreamSessionStateRecord.session_id` and deterministic `dream/session/{session_id}` refs match the decision. |
| ADR-3: Consolidation output is distilled memory plus replay metadata | ✅ Yes | Distilled memory goes to `MEMORY.md`; replay metadata persists in Dream state / `dream_sessions`. |
| ADR-4: Completion-recorded-first, Dream-evaluated-second | ✅ Yes | Gateway and hygiene flows both record completion before Dream evaluation. |
| ADR-5: Two-level locking (global runner lock plus per-session durable status) | ✅ Yes | `dream.lock` plus durable session status markers are both present. |
| ADR-6: Backend parity preserves artifacts and replay state, not identical format | ✅ Yes | SQLite, sidecar JSON, and snapshot JSON preserve semantics while using different storage formats. |
| File changes likely needed | ⚠️ Partial deviation | `memory/markdown.rs` appears less directly involved than design suggested; persistence is more centralized in `memory/dream.rs`. This is coherent with runtime ownership but should be noted. |

### Issues Found

**CRITICAL** (must fix before archive):

None.

**WARNING** (should fix):

1. Several scenarios remain only partially proven at runtime, especially export→hydrate→retrigger idempotency, transcript-omission as a direct assertion, and gateway non-expansion of public Dream HTTP surface.
2. Markdown parity is implemented mainly through Dream-side state management rather than a richer `markdown.rs` backend contract, which may be acceptable but is less explicit than the design text implied.
3. The previously observed `channels::tests::transcription_semaphore_enforces_serial_execution` failure is no longer reproducible in the refreshed evidence, but because it was previously observed, it remains a regression-monitoring concern rather than an active blocker.

**SUGGESTION** (nice to have):

1. Add direct scenario-named tests for the remaining partial matrix rows, especially export→hydrate→retrigger idempotency and public-surface non-expansion.
2. Add a focused end-to-end snapshot test that performs export, cold restore, and repeated trigger for the same `session_id` in one runtime test.
3. Add a gateway-facing test or assertion set that explicitly proves Dream integration does not introduce a new public HTTP contract.
4. If intended, document in design or implementation notes that markdown backend Dream persistence is intentionally centralized in `memory/dream.rs` + sidecar state.

### Verdict

**PASS WITH WARNINGS**

The Dream change now clears the configured verification command baseline with the refreshed Rust test evidence, and the implementation remains complete, structurally correct, and design-coherent; however, several spec scenarios still have only partial runtime proof and should receive more explicit end-to-end coverage before archive confidence is considered maximized.
