dimensional-analysis

Use when code mixes units, fixed-point precisions, scaling factors, rates, prices, shares, or conversions. Not for type-level unit modeling: use type-driven.

# Dimensional analysis

## Contract

| Field | Bound contract |
|---|---|
| Trigger | A financial, scientific, DeFi, blockchain, or off-chain codebase contains mixed units, fixed-point precisions, scaling factors, rates, prices, shares, or conversions and needs full annotation plus validation. |
| Authority | Reversible local: writes only comment-only dimensional annotations in in-scope source files plus DIMENSIONAL_SCOPE.json, DIMENSIONAL_UNITS.md, and a findings report in the project root; rollback is version control (revert comments) or undo (delete the three generated artifacts). No remote mutation. |
| Side effect | Comment-only annotations in all in-scope source files; DIMENSIONAL_SCOPE.json, DIMENSIONAL_UNITS.md, and a final findings/coverage report in the project root. No executable code, types, or logic are changed. |
| Done | Every in-scope file has terminal annotation, propagation, and validation status; no PENDING entries remain; blocked files reconcile exactly; only comments changed; confirmed and refuted mismatches are separated. |

## Inputs

- Project root path (required).
