**Overall Verdict:** Strong Accept — The revision is complete, professionally scoped, objectively evaluable, and supported by coherent executable, source, trace, transform, and visual evidence without material risk.

**Completeness Check:**
- Instruction: Complete — Defines the professional objective, scene behavior, event semantics, timing tolerances, recovery rules, deliverables, and success conditions precisely.
- Inputs: Complete — The solver archive contains the contract, environment specification, task, 18 acceptance cases, three exact 4/17/21-step scenarios, and six valid replay fixtures without evaluator-only leakage.
- Toolchain: Complete — Unity, URP, C#, macOS build support, licensing expectations, package versions, offline runtime behavior, and the standard-library evaluation environment are specified.
- Reference output: Complete — Includes an editable saved project, universal macOS player, 50 indexed sessions, raw JSONL events, independent transform observations, rendered evidence, build/reopen records, and operating and validation guides.
- Rubric: Complete — Allocates 100 points across six objective groups, defines partial-credit boundaries, evidence requirements, a 90-point threshold, and mandatory executable/scenario conditions.

**File and Task Reachability:**
Attachment classification: reachable. Task classification: reachable. Both `input_materials_r2.zip` and `reference_evaluation_r2.zip` were inspected. The input archive was inspected in full. The reference archive’s complete 1,703-entry directory and safety metadata were inventoried, followed by inspection of `ARCHIVE_MANIFEST.json`, `REVIEW_RESPONSE.md`, reference status/readme/validation/visual-review documents, run and check indexes, rubric and checker source, Unity manifests and runtime source, the serialized scene, build metadata and logs, 20 representative event traces, three transform logs, nine PNGs, and three MP4 containers. The archives are valid, unencrypted ZIPs with no unsafe paths or special entries; selected members passed CRC and submitted-manifest hash checks. Remaining Unity runtime libraries, five video payloads, most repeated-run logs, and the bulk captured-frame set were inventory and manifest reviewed but not individually decoded. The reviewer environment could not launch the macOS player or Unity and lacked a video decoder, so executable behavior was cross-checked through bundle structure, static source, raw traces, independent transforms, build/reopen evidence, and rendered frames. An ordinary evaluator with the declared macOS Unity environment has a complete build, execution, and scoring path. License keys, accounts, tokens, and other credentials are not required from the contributor. Confidential, proprietary, or internal material may be evaluated as submitted evidence without requiring additional disclosure.

**Special Screening:**
None. Public provenance was not externally searched because it falls outside the permitted evidence boundary, and no affirmative evidence supports a screening label.

**Recommended Changes:**
The revision resolves the prior executable-reference and authentic-evidence gaps comprehensively. No material changes are required.
