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). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DF9CcCuL4YJoqs26eHsYiA
Make the repo's licensing single and consistent, matching the wokelangiser reference policy and the merged iseriser pattern: - Remove contradictory PMPL-1.0-or-later / Palimpsest self-claims from README badges/footers, QUICKSTART, RSR_OUTLINE, STATE-VISUALIZER, and machine-readable governance (META, stapeln, deny.toml allow-list, copilot/AGENTIC SPDX directives, Trust/Must LICENSE-content checks, per-project CLAUDE.md). - Encode the docs split in REUSE dep5: *.adoc/*.md/docs/** -> CC-BY-SA-4.0, everything else -> MPL-2.0. - READMEs show MPL-2.0 (code) + CC-BY-SA-4.0 (docs) badges; full texts live in LICENSES/; root LICENSE stays MPL-2.0 for GitHub's licence chip. Preserves legitimate non-self references: cargo-deny's AGPL deny-list, the "never use AGPL" estate policy, and the Contributor Covenant CoC. Verified: standards/scripts/check-licence-consistency.sh passes; no residual PMPL/Palimpsest self-claims remain.

….7.0 The src/interface/abi Idris2 ABI was scaffolded from a template and never compiler-checked. This makes all three modules typecheck cleanly and adds a machine-checked Proofs module, with zero errors and zero warnings under Idris2 0.7.0 (idris2 --build tlaiser-abi.ipkg). Systemic fixes: - Types: replace the non-compiling `decEq _ _ = No absurd` catch-all in the `DecEq Result` instance with explicit off-diagonal `No (\case Refl impossible)` cases for all 8 constructors. - Types: `createHandle` now derives a real `So (ptr /= 0)` via `choose` instead of leaving the `MkHandle` auto-implicit unsolved. - Types: `thisPlatform` is a plain `Linux` value (the `%runElab` stub required ElabReflection and did not compile). - Layout: `paddingFor` uses `minus` (Nat has no `-`); imports Data.Nat. - Layout: add sound `decDivides`/`decFieldsAligned`; `checkCABI` builds a real `CABICompliant` witness instead of a `?fieldsAlignedProof` hole. - Layout: `offsetInBounds` returns `Maybe (So ...)` via `choose` (the universal `So` return type was unsound); `alignUpDivides` decides divisibility soundly. - Layout: concrete/parameterised StructLayouts supply genuine erased proofs. For the parameterised state-space/trace-step layouts the `sizeCorrect` obligation is discharged by an inductive `foldlSizes8` lemma (no axioms), and `aligned` by `DivideBy` with multiplication that reduces at the type level. Pre-existing template bugs also fixed in Types: - rename local `NonEmpty` (on StateMachine) to `StateMachineNonEmpty` so the trace obligation resolves to the Prelude list `NonEmpty` (import Data.List); - `CPtr` matches on Platform (was `Bits (ptrSize p)`, ill-typed); - `cSizeOf`/`cAlignOf` match on concrete primitive types (could not match on the `CInt`/`CSize` type-level functions). Buildability: - git mv flat files into Tlaiser/ABI/ nested namespace layout; - add src/interface/abi/tlaiser-abi.ipkg; - .gitignore now ignores **/build/, *.ttc, *.ttm. New Tlaiser.ABI.Proofs theorems (export, machine-checked): - modelCheckRequestCompliant : CABICompliant of the concrete FFI struct, built directly from per-field DivideBy witnesses; - okIsZero, stateSpaceExhaustedIsSeven : result-code encoding pins; - okDistinctFromTlcError : the encoding is injective on the switched codes.

Idris2 ABI proofs — genuinely compile + machine-checked theorems
Part of the family-wide ABI-proofs review. The hand-written ABI did not typecheck under Idris2 0.7.0; this makes it real and verified, following the merged iseriser reference.
Systemic fixes:
