Summary

Make CI genuinely green. The shared rust-ci pin on main predates standards#439, so the SHA-pinned dtolnay/rust-toolchain step errors out before the job runs. This bumps the pin so rust-ci actually runs, replaces the estate-banned Python ABI-FFI gate with the canonical Julia gate (matches verisimiser), and brings the Rust sources to fmt + clippy(-D warnings) clean.

Changes

  • rust-ci: bump rust-ci-reusable.yml pin d135b05 → 8dc2bf0 (current standards HEAD; includes #439 toolchain fix + #441/#442).
  • ABI-FFI gate: remove scripts/abi-ffi-gate.py (Python banned estate-wide); add scripts/abi-ffi-gate.jl (behaviour-identical Julia port); workflow installs Julia 1.11.5. Matches verisimiser's canonical gate.
  • Rust hygiene: cargo fmt + clippy --fix where the repo had pre-existing drift, so cargo fmt --all -- --check and cargo clippy --locked --all-targets -- -D warnings pass.

RSR Quality Checklist

Required

  • Tests pass (cargo test --locked --all-targets)
  • Code is formatted (cargo fmt --all -- --check)
  • Linter is clean (cargo clippy --locked --all-targets -- -D warnings)
  • No banned language patterns (removes the last Python file from CI)
  • SPDX license headers present on new/modified files
  • No secrets, credentials, or .env files included

As Applicable

  • ABI/FFI changes validated (gate logic preserved; conformance OK)

Testing

Verified locally with the toolchain CI uses (cargo 1.94.1, rustfmt 1.8.0): cargo fmt --check, clippy -D warnings, cargo check --locked, cargo test --locked all pass.

Add Semantics ABI proof: forbidden actions are never certified permitted
6a7e723 
Raises the Phronesiser Idris2 ABI to Layer 2 with a flagship, machine-checked
semantic proof of the repo's headline property ("provably safe ethical
constraints for AI agents").

Model: a deontic policy partitions agent actions into Allow/Deny. The
`ActionPermitted` proposition has NO constructor admitting a `Deny` verdict, so
a forbidden action is structurally uncertifiable.

Proven:
- decActionPermitted: sound + complete `Dec (ActionPermitted a)`.
- certifyPermittedSound: certifier soundness (Ok => ActionPermitted).
- safeInformPermitted: positive control (inhabited permission witness).
- forbiddenNeverPermitted: negative control / core safety theorem
  `Not (ActionPermitted forbiddenDeploy)`.
- forbiddenNeverCertifiedOk: corollary that the forbidden action is never Ok.

Non-vacuity confirmed: a deliberately false witness
`PermitAllow Refl : ActionPermitted forbiddenDeploy` is rejected by idris2
(Allow vs Deny mismatch). Build is clean (exit 0, zero warnings).

Add Layer-3 ABI invariants: monotone safety under policy composition
2448a98 
New module Phronesiser.ABI.Invariants, built over the existing Layer-2
Semantics model (Action / Verdict / verdictOf — nothing redefined). It
proves two properties strictly deeper than the Layer-2 single-action
safety theorem, both quantified over all actions and over policies:

  1. Monotone safety (downward-closure of permission): if policy p2
     tightens p1, every action p1 forbids stays forbidden under p2 —
     tightening never re-permits a previously-forbidden action; the
     permitted set only shrinks. Tightening is a proven preorder
     (reflexive + transitive).
  2. Conjunction composition: an action permitted under andPolicy p1 p2
     is permitted under each conjunct (iff via bothPermitsAnd), and the
     conjunction provably tightens each conjunct.

Includes a sound+complete Dec (Permits p a), sample policies over the
shared model, positive controls (witnesses + a live application of the
monotone-safety theorem) and negative/non-vacuity controls in Not(...)
form. %default total; no believe_me / postulate / assert_total / sorry /
asserted equalities. Builds with zero warnings; an adversarial false
proof (tightened policy permits the forbidden action) is rejected by the
type checker.

Add Layer-4 FfiSeam proof sealing the ABI<->FFI seam
057d422 
Prove the FFI result-code encoding is SOUND, not just structurally
agreed (the abi-ffi-gate.py check): distinct ABI outcomes never collide
on the wire, and the C integer faithfully round-trips back.

New module Phronesiser.ABI.FfiSeam (imports Phronesiser.ABI.Types):
- intToResult decoder + resultRoundTrip (left inverse of resultToInt)
- resultToIntInjective derived from the round-trip via justInj + cong
- same round-trip + injectivity for modalityToInt (DeonticModality)
  and severityToInt (HarmSeverity); no ProofStatus/statusToInt exists
- positive controls (concrete decode = Refl) and non-vacuity controls
  (distinct codes have distinct ints, machine-checked)

Genuine proof only: no believe_me/idris_crash/assert_total/postulate.
%default total, SPDX header, zero warnings. abi package builds clean;
an adversarial false claim (resultToInt Ok = resultToInt Error) is
rejected by the type checker.

Add Layer-5 capstone ABI soundness certificate
eae8ce0 
Assemble the existing Layer-2/3/4 proofs into one inhabited certificate
record (ABISound) and value (abiContractDischarged) in
Phronesiser.ABI.Capstone, tying the flagship safety property, the
monotone-safety invariant, and the FFI-seam injectivity into one
end-to-end soundness statement. Reuses only already-exported witnesses
(safeInformPermitted, noHarmTightensBase, forbiddenStaysForbidden,
resultToIntInjective). No new axioms; %default total; zero warnings.

…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.
