### Verification summary

This re-run clears the previous blockers.

- **Legacy webhook preview compatibility**: fixed. `legacy_webhook_preview_intercepts_slash_session_commands` now passes.
- **Rustfmt**: clean. `cargo fmt --all -- --check` passed.
- **Clippy**: clean. `cargo clippy --manifest-path Cargo.toml --all-targets -- -D warnings` passed.
- **#540 contract scope/compliance**: still aligned with the proposal/spec/design. The implementation remains confined to the shared slash-command seam (`session_commands`, `pre_execution`, targeted transport adapters, and narrow memory support) without redesigning external envelopes or introducing new command families.

### Static compliance review

| Requirement / intent | Status | Evidence |
|---|---|---|
| Typed command context exists | ✅ | `clients/agent-runtime/src/session_commands/types.rs` defines owned `CommandContext`, typed caller/ingress/session/facts models, and transport-specific builders. |
| Typed requirement metadata exists | ✅ | `types.rs` defines `SlashCommandRequirements`, `CommandCapability`, `CommandPermission`, and `CommandBackend`; `registry.rs` uses them for built-ins. |
| Registry remains descriptive, not authoritative | ✅ | `registry.rs` exposes metadata and dispatches; requirement/backend/caller enforcement remains in `service.rs`. |
| Non-lossy internal outcomes exist | ✅ | `SessionCommandOutcome::{Success, Failure}` and `IngressDecision::SessionCommand { outcome }` preserve machine-readable internal success/failure kinds. |
| `/resume` caller-scope enforcement is correct | ✅ | `service.rs` requires caller scope, uses `get_resumable_session_for_scope(...)`, denies unauthorized targets, and avoids denied-state mutation. |
| Narrow storage boundary supports `/resume {target}` visibility | ✅ | `crates/corvus-traits/src/memory.rs` adds `get_resumable_session_for_scope`; `src/memory/sqlite.rs` implements scoped suspended/resume-capable lookup. |
| Transport adapters preserve existing envelopes | ✅ | `main.rs`, `gateway/mod.rs`, `gateway/webhook_dispatch.rs`, and `channels/mod.rs` adapt typed internal outcomes back into existing CLI/HTTP/SSE/webhook/channel envelopes. |
| Scope stayed tight to #540 | ✅ | Modified runtime code stays inside the proposal/design file set and does not expand into #541-style envelope redesign. |

### Spec compliance conclusion

The change now satisfies the requested verification focus:

- typed command context and typed requirement metadata are present;
- internal outcomes remain non-lossy and machine-readable;
- `/resume` caller-scope enforcement is fixed and regression-covered;
- transport adapters preserve external envelopes without redesigning them;
- prior blockers from the first verification pass are resolved.

---

### Remaining note

I still did not find a dedicated executed test that isolates **webhook unavailable caller identity** as a runtime-distinct case from other caller forms. The code structure supports the distinction, and this is no longer a release blocker, but it remains a worthwhile follow-up regression test.

---

### Verdict

**PASS**

The implementation now passes verification for #540-focused scope and contract compliance, with previous transport compatibility and Rust quality gate blockers resolved.
