Adds Chapeliser.ABI.Invariants, a new machine-checked theorem deeper than
and distinct from the Layer-2 Partition tiling proof. Partition.idr proved
the block partition is a gapless, non-overlapping tiling for all n,k but
explicitly left open the arithmetic residual `sumNat (perItemCounts n k) = n`
("the only div/mod obligation"). This module discharges exactly that.
blockCountsComplete : (n,k') -> sumNat (blockCounts n k') = n proves every
item is covered exactly once, for ALL n and all k>0, via the Euclidean
division theorem (contrib Data.Nat.Division) plus a self-contained count of
remainder slots. Counts are expressed with the public-export divNatNZ/modNatNZ
(the reducing form of Prelude div/mod on a positive divisor) so the proof and
its concrete controls reduce at the type level.
Includes: a sound+complete Dec (decCoversExactly), positive controls
(covers10over3, covers12over4 by Refl + via the general theorem), and
non-vacuity/negative controls (notCovers10as9, dec10over3as9No,
remainderCountMatters). Genuine proof: no believe_me/postulate/assert_total/
sorry/admitted. Builds clean (0 warnings); a deliberately false variant is
rejected by the type checker.

…I.FfiSeam) Add a new module proving the Result FFI encoding is sound: - intToResult decoder + resultRoundTrip: the C integer faithfully round-trips back to the ABI Result (lossless/faithful encoding). - resultToIntInjective: distinct ABI outcomes never collide on the wire, derived from the round-trip via justInj . cong intToResult. - Positive controls (concrete decode = Refl) and a machine-checked non-vacuity control: distinct codes have distinct ints. Genuine total proofs, no believe_me/postulate/assert_total/etc. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01A6PSzJWpRxtzGDjUCEh7Mx
Assemble the existing proof layers into one inhabited certificate value in Chapeliser.ABI.Capstone: - ABISound record whose fields reuse real exported witnesses: * flagshipValid -> Proofs.tenAcrossTwoValid (Layer 2, complete+disjoint) * blockComplete -> Invariants.blockPartitionIsComplete 10 2 (Layer 3) * blockCompleteAll -> Invariants.blockCountsComplete (Layer 3, general) * ffiInjective -> FfiSeam.resultToIntInjective (Layer 4 seam) - abiContractDischarged : ABISound — the single inhabited capstone value; ties manifest -> ABI proofs (flagship + invariant) -> FFI seam into one end-to-end soundness statement. Stops typechecking if any layer weakens. No believe_me/postulate/assert_total/sorry/%hint; %default total; SPDX line 1. Build clean (0 warnings); adversarial false-field certificate is rejected.

…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
