**Overall Verdict:** Accept — The task is professionally substantive, feasible, and objectively evaluable using the supplied full-precision references; ancillary CSV exports have precision defects that do not prevent evaluation.

**Completeness Check:**

- Instruction: Complete — Clearly specifies linked views, continuous composition interpolation, phase selection, crystal inspection, portability, and deliverables.
- Inputs: Complete — Includes 1,062 structure/energy records, matching CIFs, calculation conventions, five boundary states, four interval decompositions, and all nine required phases.
- Toolchain: Complete — The declared open-source Linux tools support the workflow on one ordinary workstation; the reference embeds its scientific data.
- Reference output: Complete — Includes a connected four-view state, workbook, numerical validation records, structure exports, relocation copy, and walkthrough. Full-precision results agree with the inputs; rounded inventory CSVs are unsuitable as numerical scoring references.
- Rubric: Complete — Specifies objective tolerances, required compositions, conservation checks, source matching, interaction tests, and explicit failure conditions.

**File and Task Reachability:**

Attachment classification: `partially_reachable`. Inspected `task_03_inputs.zip`, `task_03_reference.zip`, and `task_03_evidence.zip`, including the nested crystal archive, JSON/CSV data, CIFs, workbook contents, native-state definitions, checklists, logs, screenshots, and video containers. Declared download sizes matched; archive integrity and safety checks passed.

The full-precision reference amounts, energies, and element balances agree within the required tolerances across all 20 recorded compositions. All nine reference crystal records match the supplied originals. However, `inventory_0.300000.csv` rounds reaction energy to −0.67949 rather than approximately −0.67948755625, exceeding tolerance; other CSVs also round scientific record identifiers.

Native interactions and relocated reopening were not independently exercised, and full video playback remains unreviewed because suitable runtime and decoding tools were unavailable. These are review limitations, not demonstrated submission failures.

Task classification: `reachable`. Completion and evaluation can proceed through the supplied structures and equilibrium results, a self-contained native pipeline, workbook/video exports, and direct interaction tests against the full-precision JSON and workbook. The intentionally supplied reaction results do not substitute for the required interactive implementation.

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. No affirmative evidence supports a screening label. Public availability of an identical task or protected solution was not independently verified. The single failed self-test does not establish the claimed below-1% success rate.

**Recommended Changes:**

The supplied scientific records and full-precision reference provide a usable completion and evaluation path. No contributor revision is required. Optionally regenerate the inventory CSVs with full numerical precision and exact integer identifiers; use the existing full-precision JSON/workbook for scoring.
