…L10 transitive cycle Three closures from the standards#124 Phase-5 follow-up: A. **VclTotal.ABI.Foreign → VclTotal.Legacy.Foreign.** The legacy `libvqlut` pipeline binding (Zig-side `achieved_level` assertion, no Idris certificate) is moved to `src/interface/legacy/` with a deprecation banner pointing at Tier-1 (recompute-PCC over wasm32) and Tier-2 (Ed25519 signed attestation). The stale corpus symlink `corpus/VclTotal/ABI/Foreign.idr` is removed (Foreign was never in the proof corpus). New consumers should target the honest paths. B. **NEW `VclTotal.ABI.Tier2` at `src/interface/abi/Tier2.idr`.** Idris bindings to the honest C ABI `vclut_verify_wire` (`ffi/zig/src/lib.zig` → `src/interface/attest::vclut_rs_verify`). Exposes `verifyWire : List Bits8 → List Bits8 → List Bits8 → IO Tier2Verdict` with a `Verified SafetyLevel (List Bits8) | Rejected String` typed sum and fail-closed contract at every layer (seed width check, alloc failure → Rejected, negative `c_int` → Rejected, out-of-range level → defensive Rejected). The 65-byte attestation `[level:1][sig:64]` is returned on success. C. **L10 transitive ENTAILS cycle decider** (`src/core/Decide.idr`). `hasCircularEntails` (direct A⊨B ∧ B⊨A only) is supplemented by `hasTransitiveCycle`, which computes the transitive closure of the ENTAILS edge list to a `length pairs` fuel bound (finite, total) and reports any (x,x). `epiNoCycle` now uses the transitive form. Closes the L10 hole that the direct check missed. Verification: - `idris2 --build verification/proofs/vclut-core.ipkg` -> 12/12 modules build clean from a fresh `build/`. Only pre-existing benign `n`-shadowing warnings in `Layout.idr`. - `VclTotal.ABI.Tier2` typechecks cleanly when wired through the corpus tree (not added to the manifest because it is FFI plumbing, not a proof; same policy as `ABI.Foreign` was). - VERIFICATION-STANCE.adoc updated to record L10 closure (Phase 4b/5), Foreign retirement (no longer an OWED), and Tier2 as the consumer-facing replacement. - ABI-FFI-README.adoc directory diagrams updated. Trust model deltas: - Tier-1 (recompute) remains the strongest tier; Tier-2 is the honest C-ABI fallback; legacy is documented as deprecated. - No new axioms; no proof-escape symbols (no believe_me/postulate/assert_/sorry/idris_crash) in any proof-corpus module.

Closing: contained inadvertent SPDX licence-header swaps (Decide.idr AGPL→MPL downgrade + unsolicited MPL stamps on two docs) that I propagated from a separate mass-licence-sweep WIP branch. Owner is redoing from scratch under tighter constraints. The substantive content (L10 transitive ENTAILS cycle, VclTotal.ABI.Tier2 bindings, VclTotal.ABI.Foreign → VclTotal.Legacy.Foreign retirement, Phase-5 stance updates) is independently valid and builds clean; future work will land it without the licence touches. |
