New module K9iser.ABI.Semantics proves the repo's headline property
("Wrap configs into self-validating K9 contracts"): a config that
SATISFIES a "must"-contract (a required key present whose value lies
within an inclusive numeric range) provably validates, and a config that
VIOLATES it (missing key OR out-of-range value) provably does not.
- Faithful model: Config = assoc list (Key, Nat); Contract = key + [lo,hi].
- Headline proposition `Validates c cfg` has constructors only for the
satisfying case (resolver equation + InRange via propositional LTE);
no constructor exists for a missing key or out-of-range value.
- Sound + complete `decValidates : Dec (Validates c cfg)` and `decInRange`.
- Certifier `certify` into the ABI Result code, with `certifySound` and
`certifyComplete`.
- Positive control `goodValidates` (replicas=5 in [1,10]) and two negative
controls: `badRangeNotValidates` (replicas=0) and `missingNotValidates`.
ABI builds clean (exit 0, zero warnings). A deliberately false witness
for the out-of-range config is rejected by idris2 (non-vacuity verified).

Add a second, deeper machine-checked theorem over the existing Layer-2
Semantics model, raising the Idris2 ABI to Layer 3. Proves how config
validation behaves under CONJUNCTION of K9 contracts, distinct from the
Layer-2 single-contract soundness/completeness:
- ValidatesBoth / ValidatesAll: binary and n-ary conjunction over the
existing Validates proposition.
- validatesAndIff / validatesAllConsIff: decomposition isomorphisms
(real witness round-trips, = Refl).
- validatesBothSym: commutativity of conjunction.
- decValidatesAll: sound + complete decision, built compositionally
from the Layer-2 decValidates.
- validatesAllAppend{Fwd,Bwd}: distribution of conjunction over list
append (induction on the bundle).
- validatesAllWeaken: monotonicity / downward-closure.
- certifyAll{,Sound,Complete}: certifier into the ABI Result code.
- Positive controls (twoValidatesBoth / twoValidatesBundle) and
negative / non-vacuity controls (mixedNotBoth / mixedNotBundle),
all machine-checked; resolver equations proved via resolveHead /
resolveSkip lemmas (String decEq does not reduce definitionally).
No believe_me / postulate / assert_total / sorry. %default total.
Registered last in k9iser-abi.ipkg. Clean build, zero warnings;
a deliberately-false ValidatesAll over the out-of-range config is
rejected by the type checker (non-vacuity confirmed).

Prove resultToInt is a sound wire encoding: a faithful decoder intToResult with resultRoundTrip (lossless), injectivity derived from the round-trip, positive decode controls, and a machine-checked non-vacuity control (distinct codes have distinct ints).

Assemble the prior proof layers into a single inhabited certificate value, K9iser.ABI.Capstone.abiContractDischarged : ABISound, tying manifest -> flagship (Layer 2 goodValidates) -> deeper invariant (Layer 3 twoValidatesBundle) -> FFI seam (Layer 4 resultToIntInjective) into one end-to-end soundness statement. Built purely from existing exported witnesses; no new domain theorem, no escape hatches.

…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.
