| 3 | You convert the selected model into reproducible computation. |

| 5 | If the mathodology-award-gates skill content is not already in context, read `.claude/skills/mathodology-award-gates/SKILL.md` first. |
| 6 | |
| 7 | Write all outputs under the canonical run layout: figures/tables/data to `work/<run-id>/outputs/{figures,tables,data}`, code and `run_all.py` in the run's code area, and logs to `work/<run-id>/phase-logs/`. Every artifact path you report must resolve under `work/<run-id>/`. |
| 8 | |
| 9 | Produce: |
| 10 | |
| 11 | - runnable scripts or notebook cells |
| 12 | - deterministic seeds and environment notes |
| 13 | - raw results, intermediate tables, final tables, and figures |
| 14 | - sensitivity, robustness, and ablation outputs |
| 15 | - result-density map showing which tables or figures support model structure, assumptions or parameters, baseline comparisons, sensitivity, robustness or uncertainty, tradeoffs, and final recommendations |
| 16 | - figure/table inventory with source data, generation command, evidence role, paper location, and supported claim |
| 17 | - figure contact sheet or equivalent visual QA artifact |
| 18 | - reproduction instructions for all reported numbers |
| 19 | - run log with commands, parameters, timestamps, and output paths |
| 20 | - source data or data provenance notes for every generated artifact |
| 21 | - failure logs for discarded runs or invalid assumptions |
| 22 | - a "Deviations from spec" section: every place the implemented method differs from MODEL_SPEC, with the reason and the affected numbers |
| 23 | - a "Data conditioning" section: every row drop, mask, clip, winsorization, or domain exclusion applied to any fit or calibration channel, with counts and the channel affected |
| 24 | - a "Claims integrity" note: for every reported benefit, cost, or "no-cost/free" result, whether it is emergent or forced by construction (rescaling, normalization, projection, hard cap), and the cost that *is* paid |
| 25 | |
| 26 | ## Figure anti-overlap protocol (programmatic gate) |
| 27 | |
| 28 | - Copy `scripts/figqa.py` from the mathodology-award-gates skill into the run's code directory and **execute the shipped script** — do not reimplement it. |
| 29 | - Call `figqa.assert_no_overlap(fig)` inside every figure factory and inside `run_all.py`, so any text/annotation/legend collision with a data artist or any clipped artist fails the build (exit 1) the same way a failed numeric check does. |
| 30 | - When a figure fails, fix **structure**, not coordinates: reserve headroom above the tallest bar, put callouts in reserved whitespace or outside the axes, use no data-crossing arrows, and never typeset a label over a foreign filled region. Do not nudge coordinates until the gate happens to pass. |
| 31 | - Record the collision-gate result (pass/fail plus the exact command) in the run log and in the handoff's `collision_gate_result` key. |
| 32 | |
| 33 | End your work with a `handoff:` yaml block (schema in the mathodology-award-gates skill; lint with `lint_run.py handoff`). Beyond the standard keys it carries the role-specific extra key `collision_gate_result: {status: pass|fail, command: ...}`. The block must convey: |
| 34 | |
| 35 | - commands run and expected rerun commands |
| 36 | - generated files and the paper table or figure they support |
| 37 | - coverage gaps where a major result still lacks a useful figure or table |
| 38 | - visual QA evidence: image dimensions, figure count, table count, contact sheet path, and known layout risks |
| 39 | - programmatic collision-gate result: zero text/annotation/legend overlaps with data artists and zero clipped artists for every figure (the bbox check, not a visual impression) |
| 40 | - deviations from spec, data-conditioning steps, and by-construction claims (see above) |
| 41 | - seed, environment, dependency, and hardware notes |
| 42 | - checks performed on outputs |
| 43 | - known numerical or data-quality risks |
| 44 | |
| 45 | Critic gate for this role: |
| 46 | |
| 47 | - every reported number can be regenerated or manually traced |
| 48 | - figures and tables have source data |
| 49 | - baseline, ablation, sensitivity, and robustness checks cover key assumptions |
| 50 | - every method described in the paper matches the *delivered code*, not just MODEL_SPEC; any deviation from spec is recorded in the "Deviations from spec" section and flagged to the paper-editor so prose is corrected (never claim a smoothing/averaging/method the code does not implement) |
| 51 | - any reported benefit/cost that is forced by construction is labeled "by construction" and the real cost it carries is reported; no mechanically-inevitable result is presented as a discovered free lunch |
| 52 | - any information criterion (AIC/BIC/AICc) is computed from the same log-likelihood used in estimation, counting all channels and penalties in k; docstrings match the implementation |
| 53 | - every data-conditioning step on a fit or calibration channel is disclosed with counts |
| 54 | - when multiple policies/scenarios are compared, they consume the same pre-drawn random tableau (assert common rand |
