### Completeness

| Metric | Value |
|---|---:|
| Tasks total | 9 |
| Tasks complete in tasks.md | 9 |
| Tasks incomplete in tasks.md | 0 |

All tasks in `openspec/changes/startup-staged-image-reaper/tasks.md` are marked complete, including the focused verification/lint artifact items.

### Static Correctness

| Requirement | Status | Evidence |
|---|---|---|
| REQ-8 Configuration Contract | ✅ Implemented | `MultimodalConfig` includes `staged_image_reaper_threshold_minutes: Option<u64>` and resolves the effective threshold through `effective_staged_image_reaper_threshold_minutes()` in `clients/agent-runtime/src/config/schema.rs:283-306`; validation rejects `0` in `clients/agent-runtime/src/config/schema.rs:3402-3408`. |
| REQ-7 File Staging and Cleanup | ✅ Implemented | Startup-only reaper logic lives in `clients/agent-runtime/src/channels/media.rs:17-163`; request-path `StagedImageGuard` cleanup remains intact in the same module; startup wiring exists in `clients/agent-runtime/src/main.rs:780-782,1453-1519`. |

### Design Coherence

| Decision | Followed? | Notes |
|---|---|---|
| Reaper owned by `channels/media.rs` | ✅ Yes | Matching, age checks, reporting, and deletion behavior are all kept in `media.rs`. |
| Strict filename parsing | ✅ Yes | `is_corvus_staged_image_file_name()` accepts only exact current and legacy filename shapes with allowed extensions and lowercase hex constraints. |
| Conservative `mtime` checks, fail closed | ✅ Yes | Files are skipped when `read_dir`, `file_type`, `metadata`, `modified()`, or `duration_since()` cannot be resolved safely; `NotFound` delete races are ignored. |
| Optional threshold with default 30 | ✅ Yes | Default constant remains 30 and explicit overrides flow through config + startup threshold resolution. |
| Thin command-level startup wiring | ✅ Yes | Reaper hook is invoked only from gateway, daemon, channel start, and onboarding autostart helpers; no background/per-message loop was introduced. |

### Real Execution Evidence

Commands run:

```bash
cargo test --manifest-path clients/agent-runtime/Cargo.toml staged_image_reaper_
cargo test --manifest-path clients/agent-runtime/Cargo.toml onboard_autostart_reaper
cargo test --manifest-path clients/agent-runtime/Cargo.toml config_defaults_multimodal_when_section_missing
cargo test --manifest-path clients/agent-runtime/Cargo.toml multimodal_config_deserializes_full_section
cargo test --manifest-path clients/agent-runtime/Cargo.toml multimodal_reaper_threshold_zero_rejected
cargo clippy --manifest-path clients/agent-runtime/Cargo.toml --all-targets -- -D warnings
cargo fmt --manifest-path clients/agent-runtime/Cargo.toml --all -- --check
```

Execution result summary:
- All executed commands exited 0.
- Targeted passing tests observed included:
  - `channels::media::tests::staged_image_reaper_matches_current_and_legacy_names`
  - `channels::media::tests::staged_image_reaper_rejects_near_miss_names`
  - `channels::media::tests::staged_image_reaper_deletes_only_stale_matching_files`
  - `channels::media::tests::staged_image_reaper_skips_future_timestamp_and_duplicate_execution`
  - `channels::media::tests::staged_image_reaper_treats_not_found_delete_race_as_non_fatal`
  - `tests::startup_staged_image_reaper_uses_default_and_override_thresholds`
  - `tests::startup_staged_image_reaper_routes_only_required_command_paths`
  - `tests::onboard_autostart_reaper_runs_only_when_env_guard_is_enabled`
  - `tests::onboard_autostart_reaper_stays_idle_without_env_guard`
  - `tests::startup_staged_image_reaper_logs_cleaned_file_count`
  - `config::schema::tests::config_defaults_multimodal_when_section_missing`
  - `config::schema::tests::multimodal_config_deserializes_full_section`
  - `config::schema::tests::multimodal_reaper_threshold_zero_rejected`
- `cargo clippy` passed with `-D warnings`.
- `cargo fmt --check` passed.
- Coverage threshold is not configured in `openspec/config.yaml`.
- No dedicated build command is configured in `openspec/config.yaml`; no separate build step was required beyond the passing Rust test/lint verification above.

### Spec Compliance Matrix

| Requirement | Scenario | Evidence | Result |
|---|---|---|---|
| REQ-8 | Default reaper threshold is applied | `config::schema::tests::config_defaults_multimodal_when_section_missing` + `tests::startup_staged_image_reaper_uses_default_and_override_thresholds` | ✅ COMPLIANT |
| REQ-8 | Config override changes the reaper threshold | `config::schema::tests::multimodal_config_deserializes_full_section` + `tests::startup_staged_image_reaper_uses_default_and_override_thresholds` | ✅ COMPLIANT |
| REQ-8 | Invalid reaper threshold fails startup validation | `config::schema::tests::multimodal_reaper_threshold_zero_rejected` | ✅ COMPLIANT |
| REQ-7 | Startup reaper removes stale staged images | `channels::media::tests::staged_image_reaper_deletes_only_stale_matching_files` + `tests::startup_staged_image_reaper_logs_cleaned_file_count` | ✅ COMPLIANT |
| REQ-7 | Fresh or non-matching temp files are preserved | `channels::media::tests::staged_image_reaper_deletes_only_stale_matching_files` | ✅ COMPLIANT |
| REQ-7 | Legacy Telegram staged-image filenames are still reaped | `channels::media::tests::staged_image_reaper_matches_current_and_legacy_names` + `channels::media::tests::staged_image_reaper_deletes_only_stale_matching_files` | ✅ COMPLIANT |
| REQ-7 | Duplicate startup execution remains safe | `channels::media::tests::staged_image_reaper_skips_future_timestamp_and_duplicate_execution` + `channels::media::tests::staged_image_reaper_treats_not_found_delete_race_as_non_fatal` + `tests::onboard_autostart_reaper_runs_only_when_env_guard_is_enabled` | ✅ COMPLIANT |

Compliance summary: 7/7 scenarios compliant.

### Issues Found

**CRITICAL**
- None.

**WARNING**
- None.

**SUGGESTIONS**
- None.

### Verdict

PASS

The change now satisfies the proposal, spec, design, and tasks with runtime-backed evidence for startup-only cleanup, strict filename matching, threshold behavior, startup wiring including onboarding autostart, info-level cleaned-file-count logging, and delete-race safety.
