Add Ephapaxiser.ABI.Semantics: a faithful model of single-use token state with the headline linearity property machine-checked. - Token (Fresh|Spent) with explicit consumed-state index. - Consumable t: proposition with NO constructor for the Spent (bad) case; Uninhabited (Consumable (spent token)) discharged by impossible clause. - Consumed before after: certificate of the unique Fresh -> Spent step. - consume: advances a Fresh token to Spent given Consumable evidence. - decConsumable: total, sound + complete Dec. - certifyConsume into the shared Result codes (Ok / AlreadyConsumed), with certifyConsumeSound (no believe_me) and certifySpentRejected. - Positive controls: freshTokenConsumable, consumeFreshSeven. - Negative control: spentTokenNotConsumable : Not (Consumable spent). Builds clean (exit 0, zero warnings). A deliberately false proof that a spent token is Consumable is rejected by idris2, confirming the property is non-vacuous.

Adds Ephapaxiser.ABI.Invariants over the existing Layer-2 Semantics model
(reuses Token/Consumable/Consumed/consume; no redefinition). Proves two
deeper, distinct properties of the single-use transition itself:
1. NO-RESURRECTION (irreversibility): the spent post-state of any Consumed
certificate is never Consumable (postStateNotConsumable). Transition
soundness — every reachable post-state is dead.
2. DETERMINISM (uniqueness): the certificate is unique for a given source/
target (consumedUnique), the result identity is single-valued
(consumeResultDeterministic), with a sound+complete Dec (decConsumedEq)
and identity-preservation round-trip lemmas.
Includes positive controls (concrete inhabited witnesses) and negative/
non-vacuity controls (no-resurrection refutation; distinct ids stay distinct).
No axioms: no believe_me/idris_crash/assert_total/postulate/asserted equalities.
Builds clean (exit 0, zero warnings); both deliberately-false adversarial
proofs rejected. Registered last in ephapaxiser-abi.ipkg.

Prove the FFI result-code encoding resultToInt : Result -> Bits32 is sound: - intToResult decoder + resultRoundTrip (lossless/faithful encoding) - resultToIntInjective derived from the round-trip via justInj + cong - positive controls (concrete decodes = Refl) - non-vacuity controls (distinct codes have provably distinct ints) No ProofStatus/statusToInt enum exists in this repo, so only Result is sealed. Genuine total proof: no believe_me/postulate/assert_total/sorry. Builds clean with zero warnings; adversarial false claims (Ok=Error) rejected.

Add Ephapaxiser.ABI.Capstone assembling the existing proof layers into one
inhabited certificate:
- ABISound record: flagship single-use witness (Semantics.freshTokenConsumable),
Layer-3 NO-RESURRECTION invariant (Invariants.noResurrectionThree), and
FFI-seam injectivity (FfiSeam.resultToIntInjective).
- abiContractDischarged : ABISound built solely from those real exported
witnesses — typechecks iff every prior layer is sound.
- Two positive-control projections + doc comment tying manifest -> ABI proofs
-> FFI seam into one end-to-end soundness statement.
Genuine composition only: no believe_me/postulate/assert_total/%hint. Build is
clean with zero warnings; an adversarial false certificate (positive Consumable
witness in the Not(Resurrection) field) is rejected by the type checker.

…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
