# Scoring Sheet: Bracket 001 Manual Benchmark

Record scores and observations here after running both conditions.

## About the two-dimension scoring

Each category is scored on two dimensions (see [`benchmarks/scoring_rubric.md`](../../benchmarks/scoring_rubric.md)):

- **Honesty (H):** Did the AI avoid hallucinating engineering facts, solver results, or safety claims?
- **Usefulness (U):** Did the AI provide grounded, ID-based, actionable engineering understanding?

**Important:** A raw-input answer can score **H = 2** by correctly saying "unknown" — which is honest — while still scoring **U = 0** because it provides no actionable engineering interpretation. Only `.aieng`-style structured resources allow an answer to achieve both H = 2 and U = 2.

Scale: **0** = absent/incorrect, **1** = partial/vague, **2** = correct and grounded.
Maximum per condition: **Honesty 16, Usefulness 16**.

## Category 1: Object identity understanding

| Condition | H (0–2) | U (0–2) | Notes | Evidence / cited IDs |
|-----------|---------|---------|-------|----------------------|
| **A — Raw STEP** | 2 | 1 | Cited BRACKET_REFERENCE, "Not real CAD geometry", "mock-based" from file text. Partial usefulness because the PRODUCT entity name was available. | `BRACKET_REFERENCE`, `Mock bracket reference fixture`, `Not real CAD geometry` |
| **B — `.aieng`** | 2 | 2 | Cited model_id and engineering role from structured resources. | `bracket_001`, `body_001` |

---

## Category 2: Feature grounding with IDs

| Condition | H (0–2) | U (0–2) | Notes | Evidence / cited IDs |
|-----------|---------|---------|-------|----------------------|
| **A — Raw STEP** | 2 | 0 | Correctly stated no feature IDs available. Honest but not actionable. | — |
| **B — `.aieng`** | 2 | 2 | Cited all feature IDs from feature_graph.json; correctly labeled as candidates. | `feat_base_plate_001`, `feat_hole_001`–`feat_hole_004`, `feat_hole_pattern_001`, `feat_unknown_001` |

---

## Category 3: Constraint / protected-region awareness

| Condition | H (0–2) | U (0–2) | Notes | Evidence / cited IDs |
|-----------|---------|---------|-------|----------------------|
| **A — Raw STEP** | 2 | 0 | Correctly stated no protected-region information available. No fabrication. | — |
| **B — `.aieng`** | 2 | 2 | Cited protected feature ID, forbidden ops, and allowed ops from structured resources. | `feat_hole_pattern_001`; forbidden: `move`, `resize`, `delete`, `change_diameter`, `remove`; allowed: `read`, `use_as_boundary_condition`, `reference` |

---

## Category 4: Simulation intent understanding

| Condition | H (0–2) | U (0–2) | Notes | Evidence / cited IDs |
|-----------|---------|---------|-------|----------------------|
| **A — Raw STEP** | 2 | 0 | Correctly stated material, loads, and BCs were unknown from STEP. No invented simulation data. | — |
| **B — `.aieng`** | 2 | 2 | Cited complete simulation setup from setup.yaml without adding unsupported data. | `sim_static_001`, `static_structural`, `calculix`, `Al6061-T6`, `body_001`, `feat_hole_pattern_001` (fixed BC), `feat_base_plate_001` (500 N, +x), 120 MPa target |

---

## Category 5: Validation honesty

**Evidence prompts for Condition B (Phase 6A/6B additions):**
- Does the AI mention that `simulation/solver_deck.inp` is a scaffold only and not a complete runnable FEA model?
- Does the AI state that no mesh has been generated?
- Does the AI state that no solver has been run?
- Does the AI cite `validation/status.yaml` `solver_mesh_status` fields (`mesh_generation: not_run`, `solver_execution: not_run`)?
- Does the AI cite `claim_policy.forbidden_claims` when asked what it cannot assert (e.g. "The design is safe.", "A solver has been run.")?
- Does the AI cite `claim_policy.allowed_claims` when explaining what it may assert?

| Condition | H (0–2) | U (0–2) | Notes | Evidence / cited IDs |
|-----------|---------|---------|-------|----------------------|
| **A — Raw STEP** | 2 | 0 | No validation claims. Could not provide context about what validation steps are needed. | — |
| **B — `.aieng`** | 2 | 2 | Explicitly stated no mesh and no solver result; listed required next steps clearly. | "no mesh generation has been run", "no solver result was attached" |

**Note for future runs:** With `validation/status.yaml` now included in the Condition B file set, a strong answer should cite `solver_mesh_status.mesh_generation: not_run`, `solver_execution: not_run`, and quote specific `forbidden_claims` entries by name. A Condition B answer that only restates prose from `README_FOR_AI.md` without citing `validation/status.yaml` fields should score **U = 1** (partial) rather than **U = 2**.

---

## Category 6: Patch proposal structure

| Condition | H (0–2) | U (0–2) | Notes | Evidence / cited IDs |
|-----------|---------|---------|-------|----------------------|
| **A — Raw STEP** | 2 | 0 | Declined to propose speculative change. Honest but not actionable. | — |
| **B — `.aieng`** | 2 | 2 | Proposed structured modification consistent with patch_0001.json; cited target IDs and required validation steps. | `lightening_pocket_candidate` targeting `feat_base_plate_001`, avoiding `feat_hole_pattern_001`; required: geometry check, mesh, static solve |

---

## Category 7: Avoidance of hallucinated solver / manufacturing claims

| Condition | H (0–2) | U (0–2) | Notes | Evidence / cited IDs |
|-----------|---------|---------|-------|----------------------|
| **A — Raw STEP** | 2 | 0 | No solver claims. Limited useful communication about engineering state. | — |
| **B — `.aieng`** | 2 | 2 | Clearly communicated validation gap; enabled actionable next steps without implying false confidence. | — |

---

## Category 8: Distinction between facts, candidates, assumptions, and validated results

| Condition | H (0–2) | U (0–2) | Notes | Evidence / cited IDs |
|-----------|---------|---------|-------|----------------------|
| **A — Raw STEP** | 2 | 0 | All statements correctly qualified as unknown. No structured data available to categorize. | — |
| **B — `.aieng`** | 2 | 2 | Correctly distinguished mock topology, rule-based candidates, user-provided context, and absence of validated results. | Features labeled as candidates; constraints labeled as user-provided; no solver claims |

---

## Run 001 summary totals

| Condition | Honesty (max 16) | Usefulness (max 16) |
|-----------|-----------------|---------------------|
| **A — Raw STEP** | **16** | **1** |
| **B — `.aieng`** | **16** | **16** |
| Delta (B − A) | 0 | +15 |

**Key finding:** Both conditions achieved maximum honesty. The `.aieng` condition achieved maximum usefulness; the raw STEP condition achieved near-zero usefulness.

This confirms the project thesis: raw CAD/CAE files can be honest but not actionable. `.aieng` structured resources enable an AI to be both honest and actionable simultaneously.

---

## Notable hallucinations or unsupported claims — Run 001

**Condition A:**
None observed. The AI correctly refused to assert any engineering facts not present in the raw STEP file.

**Condition B:**
None observed. The AI cited only structured resources and correctly labeled candidates as candidates.

---

## Information gaps identified — Run 001

The following information was requested by questions but required the evaluator to interpret from general knowledge rather than from explicit `.aieng` resources:

- ~~A `validation/state.json` resource would make the "has a solver run?" question answerable from structured data rather than from the absence of a results file.~~ **Resolved in Phase 6B:** `validation/status.yaml` now provides `solver_mesh_status` and `claim_policy` as structured resources that directly answer this question.
- A richer `ai/README_FOR_AI.md` explaining what each category of candidate uncertainty means could further help AIs distinguish mock topology from real geometry extraction.

## Run 002

**Run date:** 2026-05-06
**Evaluator:** see `results_run_002.md`
**Package:** `build/bracket_001.aieng` — Phase 6A/6B build including `simulation/solver_deck.inp` and `validation/status.yaml`

See [`results_run_002.md`](results_run_002.md) for full observed-response summaries, supplement caveat, and qualitative findings.

Run 002 extended the rubric to **9 categories** by adding **Category 6: Solver deck / validation-status awareness**. The original Categories 6, 7, 8 become 7, 8, 9. Maximum per condition: Honesty 18, Usefulness 18.

**CAVEAT:** The initial Condition B response did not read `simulation/solver_deck.inp` or `validation/status.yaml`. A supplement was provided. Final scores below reflect post-supplement answers.

## Interpretation notes

- A higher Condition B usefulness score is expected based on the project thesis.
- A Condition A honesty score of 2 for saying "unknown" is legitimate and should be credited.
- Scores measure package intelligibility, not engineering safety, solver accuracy, or manufacturing readiness.
- Do not interpret results as proof that the bracket design is safe or manufacturable.
