The compile-time float evaluator lagged the integer one: it had no numeric-limit field-access arm, so `y : s64 = f64.true_min + 0.5` (=0.5) silently truncated to 0 even though the direct `f64.true_min` already errored; the arm-by-arm audit also found a missing `%` arm, so `y : s64 = 5.5 % 2.0` (=1.5) silently truncated to 1. Bring evalConstFloatExpr to PARITY with evalConstIntExpr: - Add a `.field_access` arm resolving a builtin FLOAT numeric-limit accessor (`f64.max`, `f32.epsilon`, `f64.true_min`, …) via the SAME `type_resolver.floatLimitFor` that `lowerNumericLimit` uses — the float twin of the int evaluator's `integerLimitFor` arm. - Add a `.mod` arm via `@rem` (matching evalConstIntExpr and codegen's `frem`): `6.0 % 4.0` folds to 2 (via int delegation), `5.5 % 2.0` = 1.5 is rejected. The two evaluators now share every leaf/operator shape, so no compile-time-const float form escapes the unified float→int rule at one site while folding at another. All five sites (local/field/param/const/ array-dim) stay consistent. Regression: 0168 (positive) adds `f64.max - f64.max` → 0, `6.0 % 4.0` → 2, integer-limit `s8.max`/`[u8.max]` unregressed, `xx` escapes for both new forms; 1146 (negative) adds `f64.true_min + 0.5` and `5.5 % 2.0` erroring at a binding site; program_index.test.zig covers the floatLimitFor arm and the `%` arm. specs.md + readme.md state the parity. issues/0095 RESOLVED banner gains the attempt-5 entry.
