Add Mylangiser.ABI.Semantics, a machine-checked flagship proof for the
headline domain property: progressive-disclosure interfaces only ever ADD
revealed items across steps, never remove a previously-shown one.
Model: a disclosure run is a sequence of revealed-item sets (List (List Nat)).
A valid step Reveal before after exists only when Subset before after holds
(every item visible before is still visible after) — there is no constructor
that drops a revealed item. MonotoneRun is the transitive closure over steps.
Includes a sound+complete decision procedure (decSubset, decReveal, decRun),
a certifier into the ABI Result type with a soundness lemma (certifyRunSound),
a positive control (goodRunMonotone: {1}->{1,2}->{1,2,3}) and a negative
control (hidingStepInvalid / hidingRunNotMonotone: {1,2}->{1} has no valid
transition proof). No believe_me/postulate/assert — fully total.

Adds a second, deeper, distinct machine-checked theorem over the existing Semantics model. Where Layer 2 proves single-step monotonicity (one Reveal step may only add items), Layer 3 proves the multi-step disclosure relation Reaches is transitive (reachesTrans) and that reachability implies a global Subset (reachesImpliesSubset) — revealed sets only grow across many steps, a fact not implied by the local theorem. Includes the load-bearing algebraic laws subsetElem/subsetTrans/subsetRefl, a sound+complete decision procedure, a Result certifier with soundness extraction, a positive control (concrete two-hop reachability witness whose growth is machine-derived), a composed-path witness via transitivity, and negative/non-vacuity controls (hidingNotSubset, hidingNotReachable, hidingCertifyRejected). Builds clean with zero warnings; adversarial false claims are rejected by the checker.

Seals the proof side of the ABI<->FFI seam: the FFI result-code encoding resultToInt : Result -> Bits32 is proven SOUND. - intToResult decoder + resultRoundTrip: encoding is lossless/faithful - resultToIntInjective: distinct ABI outcomes never collide on the wire, derived from the round-trip via cong + Just-injectivity - same round-trip + injectivity for disclosureLevelToInt (the other FFI enum encoder in this ABI) - positive controls (concrete decode = Refl) and a machine-checked non-vacuity control (distinct codes have distinct ints) Genuine proof only: no believe_me/idris_crash/assert_total/postulate. %default total throughout. Builds clean with zero warnings; a false seam claim (resultToInt Ok = resultToInt Error) is rejected by the checker.

Assemble the existing Layer-2/3/4 ABI proofs into one inhabited end-to-end certificate, Mylangiser.ABI.Capstone: - ABISound record whose fields are the key proven ABI facts: flagship single-step monotonicity (Semantics.goodRunMonotone), the Layer-3 global invariant (Invariants.goodReachGrows), and the FFI-seam injectivity theorem (FfiSeam.resultToIntInjective). - abiContractDischarged : ABISound, the single inhabitant built entirely from those real exported witnesses. It type-checks iff every prior layer is sound, tying manifest -> ABI -> FFI seam into one soundness statement. Genuine composition only: no believe_me / idris_crash / assert_total / postulate / sorry. Adversarial check confirmed a bogus globalInvariant field (Subset [2] [1,2,3] vs required Subset [1] [1,2,3]) is rejected. Build is clean with zero warnings; %default total; SPDX header.

…ble fix); port ABI-FFI gate Python->Bash (Python is estate-banned) Resolves the standing baseline CI reds (rust-ci toolchain error, governance Language/anti-pattern, governance workflow-lint) without altering the proven ABI. The Bash gate reproduces the former Python gate's verdict verbatim (validated across all -iser repos) and catches the same drift classes.

Summary
Make CI genuinely green. The shared rust-ci pin on
mainpredates standards#439, so the SHA-pinneddtolnay/rust-toolchainstep errors out before the job runs. This bumps the pin so rust-ci actually runs and replaces the estate-banned Python ABI-FFI gate with the canonical Julia gate (matchesverisimiser). The Rust sources are already fmt + clippy(-D warnings) clean.Changes
rust-ci-reusable.ymlpind135b05→8dc2bf0(currentstandardsHEAD; includes #439 toolchain fix + #441/#442).scripts/abi-ffi-gate.py(Python banned estate-wide); addscripts/abi-ffi-gate.jl(behaviour-identical Julia port); workflow installs Julia 1.11.5. Matchesverisimiser's canonical gate.RSR Quality Checklist
