Add Iseriser.ABI.Semantics proving the headline domain property: a generated -iser scaffold is Conformant exactly when all five required components (Manifest, Idris2 ABI, Zig FFI, Codegen, Rust CLI) are present. Conformant is built from genuine Data.List.Elem membership obligations with no catch-all constructor, so a scaffold missing any component has no witness. Includes a sound+complete decConformant : (s) -> Dec (Conformant s), a soundness fact certifyConformantSound, a positive control (completeIsConformant via explicit Elem positions), and a negative control (ffiMissingNotConformant : Not (Conformant ffiMissing)). Non-vacuity confirmed: a deliberately-false Has Ffi witness for the FFI-missing scaffold is rejected by idris2.

Add Iseriser.ABI.Invariants over the existing Layer-2 Semantics model
(Component/Scaffold/Has/Conformant). Two new, deeper, distinct theorems:
1. Generation soundness (correct-by-construction): genScaffold provably
emits (s ** Conformant s) for any LanguageModel, with a corollary
tying it back to the Layer-2 certifier (conformantCertifies).
2. Upward-closure / monotonicity: conformantStable proves Conformance is
preserved under extension, via a genuine Elem-weakening lemma
(elemAppendRight) — an algebraic closure law, not the Layer-2 decision.
Includes a sound+complete Dec (decExtendConformant), a positive control
(extendedGeneratedConformant) and a non-vacuity negative control
(extendedBrokenNotConformant : Not ...). Builds clean with zero warnings;
adversarial false proof rejected. No believe_me/postulate/assert_total.

Add Iseriser.ABI.FfiSeam proving the resultToInt encoding is sound: - intToResult decoder + resultRoundTrip (lossless/faithful encoding) - resultToIntInjective derived from round-trip (distinct outcomes never collide on the wire) - positive controls (concrete decodes by Refl) and a machine-checked non-vacuity control (resultToInt Ok /= resultToInt Error) Genuine total proof: no believe_me/postulate/assert_total/etc. Registered in iseriser-abi.ipkg; package builds clean with zero warnings.

Assemble the existing Layer-2/3/4 ABI proofs into one inhabited value,
Iseriser.ABI.Capstone.abiContractDischarged : ABISound, with fields:
- flagship : Conformant Semantics.completeScaffold
(reuses Semantics.completeIsConformant)
- invariant : Conformant (extend [Manifest] generatedScaffold)
(reuses Invariants.extendedGeneratedConformant)
- ffiInjective : resultToInt injectivity
(reuses FfiSeam.resultToIntInjective)
Pure composition of already-exported witnesses: if any prior layer were
unsound the capstone would not typecheck. Adversarial check confirms a
wrong-type witness in the flagship slot is rejected. %default total, SPDX,
zero warnings. ipkg updated (Capstone listed last).

…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. Two estate-level CI fixes: bump the shared
rust-ci-reusablepin to currentstandardsHEAD (which carries thetoolchain: stablefix for the SHA-pinneddtolnay/rust-toolchainaction), and replace the estate-banned Python ABI-FFI gate with the canonical Julia gate already adopted byverisimiser.Changes
rust-ci-reusable.ymlpind135b05→8dc2bf0.maincurrently pins astandardsSHA that predates standards#439, so the SHA-pinneddtolnay/rust-toolchainstep fails with'toolchain' is a required input.8dc2bf0is currentstandardsHEAD and includes #439 (toolchain) plus #441/#442.scripts/abi-ffi-gate.py(Python is banned estate-wide) and addscripts/abi-ffi-gate.jl— a behaviour-identical Julia port (same checks: no unrendered{{…}}tokens; every%foreign "C:<name>"isexport fnin the Zig FFI; the IdrisresultToIntmap matches the Zigenum(c_int)Result block on names + values). The workflow now installs Julia 1.11.5 and runs the Julia gate. Matches the canonical gate already inverisimiser.RSR Quality Checklist

Testing
ABI-FFI gate verdict verified locally against an algorithm-identical reference port:
ABI-FFI GATE: OK. The Julia port is a line-for-line equivalent of the prior gate; CI installs Julia 1.11.5 to run it.🤖 Generated with Claude Code
