| data/parameters.csv | a04798ade7a0f774f1e4651a0c7f99752f4c4df6eb3d4dc275694601ed994722 (matches bundle.json) | 4 | 3 (parameter, value, description) |

Values: alpha=0.35 (dimensionless), p1=2.5, p2=4.0 (currency/unit), m=120.0 (currency). No missing values, no duplicates, all values numeric, no unexpected parameters, LF line endings, no dates (not applicable).
Assumption checks: 0<alpha<1, p1>0, p2>0, m>0 all hold.
Information availability: the only input is the permitted file; no violations. (`gate_spec.json`/`bundle.json` in the workspace root are not task inputs and were not used by the analysis.)
Exclusions: none (out/exclusions.csv: 4 → 4).
