From ffc53296e315bed1d4437de1cfc536196377e864 Mon Sep 17 00:00:00 2001 From: "Jonathan D.A. Jewell" Date: Fri, 26 Jun 2026 11:20:29 +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 all four modules typecheck cleanly under Idris2 0.7.0 with zero errors and zero warnings, and adds real machine-checked theorems. Types.idr: - thisPlatform: replaced unenabled %runElab with plain value (Linux). - DecEq BQNPrimitive: replaced "No absurd" catch-all with explicit off-diagonal cases for every ordered distinct constructor pair; Arith/Compare diagonals decided via their Char field's decEq. - DecEq Result: same explicit off-diagonal expansion. - createHandle: solve the {auto So (ptr/=0)} obligation via Data.So.choose instead of leaving MkHandle's proof unsolved. - rankNonNeg: prove r>=0 by casing on r (compare-based >= does not reduce symbolically). Layout.idr: - paddingFor: use Data.Nat.minus instead of Nat subtraction (no Neg). - arraySizeMinHeader: discharge the ?hole with a genuine So proof via a geEight lemma over the reassociated header sum. - Divides/decDivides: sound divisibility decision procedure. - alignUpCorrect (unsound Refl) replaced by alignUpDivides via decDivides. - StructLayout concrete value cbqnArrayDescLayout: supply erased proofs {sizeCorrect = Oh} and {aligned = DivideBy 2 Refl}. - CABICompliant upgraded to carry a FieldsAligned witness; added decFieldsAligned and a sound checkCABI returning Either. - offsetInBounds: honest Maybe (So ...) via choose instead of an unsound universally-quantified So. Proofs.idr (new): export-level machine-checked theorems — cbqnArrayDescCompliant (direct DivideBy witnesses), okIsZero, nullPointerIsFour, numberTagIsZero, arrayTagIsSix, scalarSingleElement. Build: added src/interface/abi/bqniser-abi.ipkg; moved flat modules into src/interface/abi/Bqniser/ABI/ so paths match namespaces. .gitignore now ignores **/build/, *.ttc, *.ttm. No believe_me/assert_total/idris_crash/postulate/%hint/holes anywhere.
