From db6b57d1421364153e11e70f605cc50dd38078c4 Mon Sep 17 00:00:00 2001 From: "Jonathan D.A. Jewell" Date: Fri, 26 Jun 2026 11:20:30 +0000 Subject: [PATCH 1/3] Add SPDX header to LICENSE and set Cargo.toml license field The governance/licence-consistency check requires an SPDX-License-Identifier header on the LICENSE file and a `license` field in the manifest. The LICENSE body is MPL-2.0 text, so stamp `SPDX-License-Identifier: MPL-2.0` (matching the actual body) and set `license = "MPL-2.0"` (replacing `license-file`). Verified with standards/scripts/check-licence-consistency.sh (passes).

This makes the whole ABI build clean (zero errors, zero warnings) under Idris2 0.7.0 with real, machine-checked proofs. Types.idr: - thisPlatform: drop %runElab (ElabReflection not enabled); plain Linux. - DecEq Result / DecEq DafnyTarget: replace non-compiling `No absurd` catch-alls with explicit off-diagonal `No (\case Refl impossible)`. - createHandle: solve the {auto So (ptr /= 0)} proof via `choose`. - Rename record field `parameters` -> `params` (reserved keyword). - CPtr/cSizeOf/cAlignOf: cannot pattern-match on Type; replace the ill-typed `Bits (ptrSize p)` and type-matching with a sound CScalar tag and platform dispatch. Drop the vacuous HasSize/HasAlignment. Layout.idr: - paddingFor: use Nat `minus` instead of `-` (Nat has no Neg). - Add sound decDivides / decFieldsAligned; implement checkCABI to build a real FieldsAligned witness (no ?hole). - alignUpCorrect: replace fake `Refl` proof with sound decAlignUp. - verifyLayout: supply sizeCorrect (choose) and aligned (decDivides). - offsetInBounds: unsound universal `So` -> `Maybe (So ...)` via choose. - Concrete StructLayouts: supply erased proofs {sizeCorrect = Oh} and {aligned = DivideBy k Refl}. - Rename shadowing implicit `n` -> `k` to clear warnings.
