## Correctness (Static — Structural Evidence)

| Requirement | Status | Notes |
|------------|--------|-------|
| Slash-session ingress classification | ✅ Implemented | Shared `evaluate_ingress` helper intercepts recognized commands before normal blocking or agent execution and is wired through gateway, webhook dispatch, channels, stream, and CLI paths. |
| Deterministic non-LLM handling path | ✅ Implemented | `SessionCommandService` handles classification outcomes without provider/tool execution; failure responses remain deterministic through `SessionCommandError` mapping. |
| Dedicated SQLite snapshot/state persistence | ✅ Implemented | `session_snapshots` and `session_state` are additive, authoritative tables distinct from generic memory rows. |
| TLDR persistence | ✅ Implemented | `/tldr` persists a dedicated snapshot, updates state, and returns a deterministic summary. |
| Compact / suspend / resume semantics | ✅ Implemented | `/compact` creates resume-capable snapshots, `/suspend` and `/resume` now validate actual snapshot records before mutating state, and ended-session resume is rejected. |
| Resume hydration path | ✅ Implemented | `pending_hydration_snapshot_id` is consumed atomically through `take_pending_resume_hydration`, and the first subsequent turn gets prepended persisted resume context once. |

---

## Coherence (Design)

| Decision | Followed? | Notes |
|----------|-----------|-------|
| Dedicated `session_commands` module | ✅ Yes | Implemented with parser, registry, service, and types. |
| Parse at ingress before autosave/memory enrichment | ✅ Yes | `evaluate_ingress` is called ahead of normal prompt side effects in the touched entrypoints. |
| SQLite-only authoritative backend | ✅ Yes | Service gates on SQLite and non-SQLite backends return explicit unsupported errors. |
| Reuse `sessions` only for identity/listing | ✅ Yes | `sessions` stays the identity/listing source; dedicated state/snapshot tables hold slash-session truth. |
| Resume via persisted pending hydration marker | ✅ Yes | `pending_hydration_snapshot_id` bridges `/resume` and the next normal turn through `DefaultMemoryLoader`. |
| Validate actual resume-capable compact snapshot before suspend/resume mutation | ✅ Yes | `handle_suspend` and `handle_resume` now resolve and verify snapshot existence, kind, ownership, and resume capability before state mutation. |

## Issues Found

**CRITICAL**
- None

**WARNING**
- Verification in this continuation relied on the supplied passing command results plus current code inspection rather than re-running the commands again.

**SUGGESTION**
- Consider adding one future end-to-end persisted resume integration test that covers `/resume {session_id}` followed by the next conversational turn through a single ingress path, even though the current split regression coverage already satisfies the spec.

---

## Verdict

PASS WITH WARNINGS

The previous verification failures are resolved: snapshot validation now guards `/suspend` and `/resume`, the missing regression coverage is present, targeted validation passed, and the implementation now matches the proposal, design, tasks, and delta specs.
