# v2.4 Full Review Report

Packet reviewed: `Substrate_Mesh_Runtime_Selected_Route_Runner_Final_Release_v2_4_OSF_READY.zip`

## Review verdict

**Decision:** `ACCEPT_FOR_LOCAL_USE`

**Release posture:** `FINAL_RELEASE_PACKET_HELD_WITH_HUMAN_USE_REVIEW_REQUIRED`

No repair patch is required from this review. The packet is suitable as the final OSF-ready release packet for a local/static selected-route runner, provided the published/readme language preserves the included boundaries and known limitations.

## Integrity review

| Gate | Result |
|---|---:|
| Outer ZIP opens | PASS |
| SHA-256 sidecar matches | PASS |
| Computed ZIP SHA-256 | `f4bf4e244b78185ec85e0f16e14f736f84c7246ab0916b6550297068d5b0b06b` |
| Internal `SHA256SUMS.txt` | PASS |
| Internal checksum entries | 129/129 |
| Required top-level files present | PASS |

## Runtime review

The selected-route runner was executed from a disposable copy of the final packet contents.

```text
Selected Route Runner v2.1: PASS
Selected source nodes loaded: 12
OAM pressure status: PASS
```

| Runtime gate | Result |
|---|---:|
| Runner command works | PASS |
| Selected route resolves | PASS |
| Selected source nodes loaded | 12/12 |
| OAM pressure status | PASS |
| Source-return status | PASS |
| Human review required | TRUE |
| Final validation claim | FALSE |

## Validation harness review

The bundled validation harness was executed from a disposable copy of the final packet contents.

```text
Selected Route Runner Validation Harness v2.2.1: PASS
Runner execution: PASS
Failure count: 0
```

| Harness gate | Result |
|---|---:|
| Immutable input verification | PASS |
| Disposable workspace execution | PASS |
| Deterministic output comparison | PASS |
| Schema validation | PASS |
| Source binding validation | PASS |
| OAM receipt validation | PASS |
| Cockpit overlay validation | PASS |
| Human review validation | PASS |
| Boundary compliance validation | PASS |
| Failure count | 0 |
| Warning count | 0 |

## Evidence/source-binding review

| Evidence gate | Result |
|---|---:|
| Selected route evidence index rows | 12 |
| Runner source evidence binding rows | 12 |
| Normalized source evidence output rows | 12 |
| Source-return status | PASS |
| Human review requirement | present |
| Source-use boundary | present on rows |

Noted limitation already recorded by the packet: one or more evidence rows are hydrated but truncated. This is visible in the runner summary and does not break source-return status.

## OAM / route receipt review

| Field | Observed |
|---|---:|
| H | 1.0 |
| I | 1.0 |
| R | 1.0 |
| A | 1.0 |
| P | 0.0 |
| S_effective | 1.0 |
| Boundary status | HELD |
| Claim limit | route-integrity pressure read only; not final validation |
| Human review required | TRUE |

## Cockpit review

The cockpit preview is a single static `index.html` with embedded JSON. Static inspection found:

| Cockpit gate | Result |
|---|---:|
| Static HTML present | PASS |
| Embedded overlay JSON parses | PASS |
| Evidence rows in overlay | 12 |
| Route summary present | PASS |
| OAM receipt present | PASS |
| Human review gate present | PASS |
| External `<script src>` references | none found |
| `fetch()` calls | none found |
| External network intent | none found |

Note: headless Chromium `file://` rendering in this sandbox failed due container/browser environment errors (`dbus`, `inotify`, `crashpad`) and returned no DOM. The HTML itself was statically validated, the embedded JSON parsed cleanly, and the bundled validation harness reports cockpit overlay validation as PASS.

## Boundary and claims review

The release documents preserve the required boundaries:

- local/static only;
- source artifacts remain read-only;
- deterministic selected-route runner;
- no arbitrary artifact code execution;
- no external calls;
- no publication authority;
- no final validation claims;
- human review required.

## Documentation review

| Document | Review result |
|---|---:|
| `README.md` | PASS |
| `FINAL_LOCAL_RUN_INSTRUCTIONS_v2_4.md` | PASS |
| `V2_4_FINAL_VALIDATION_RECEIPT_BUNDLE.md` | PASS |
| `V2_4_HUMAN_REVIEW_CHECKLIST.md` | PASS |
| `V2_4_KNOWN_LIMITATIONS.md` | PASS |
| `V2_4_BOUNDARY_AND_CLAIMS_LIMIT.md` | PASS |
| `RELEASE_MANIFEST.json` | PASS |

## Findings

### Strengths

1. The final package integrity holds: outer ZIP hash, sidecar, and internal checksums all pass.
2. The runnable selected-route runner works from a disposable copy.
3. The repaired mutation-isolated validation harness works and reports zero failures.
4. The selected route remains bounded to one route and 12 source evidence rows.
5. The source/synthesis boundary is clear in the packet, cockpit overlay data, route packet, and review docs.
6. The packet preserves the no-execution/no-external-call/no-publication/no-final-validation posture.

### Warnings / limitations

1. Human review remains required before downstream use or public claims.
2. The runner is single-route only.
3. At least one evidence row is hydrated but truncated; the row remains visible and source-return still passes.
4. The cockpit is static/local and was not successfully browser-rendered in this sandbox due environment-level Chromium failure, not a packet-level HTML parsing failure.

## Final decision

```text
ACCEPT_FOR_LOCAL_USE
```

This is acceptable as the final local/static selected-route runner release packet. No v2.4.1 repair is required from this review.

## Clean lock

```text
v2.3 packaged the runnable runner and clean validation harness as a release candidate.
v2.4 final packaging holds.
Full review finds no blocking repair issue.
Human use review remains required for downstream claims, publication, deployment, or external validation.
