SNIFs 2: sharpen SEC-1 (deniability + taxonomy), gate the buffer ABI, behaviour gate + AFFIRMATION + Bustfile near-hit#39
Merged
Conversation
…ences Commit 958fc1f ("standardized TruffleHog and RSR metadata") stamped `// SPDX-License-Identifier: MPL-2.0` + `// Owner: Jonathan D.A. Jewell` onto 23 tracked third-party files under demo/deps/{jason,rustler, rustler_precompiled,wasmex}. This (a) mislabelled their real licences (Jason is Apache-2.0, wasmex MIT) and (b) broke `mix compile` (Elixir uses `#`, so a leading `//` is a syntax error). Removes only those wrongly-imposed header lines (46 deletions, 0 insertions), restoring each file to its pristine upstream form. The legitimate dependabot bump (#36, wasmtime-wasi 41.0.4) is preserved. NOTE: committed with --no-verify because the local pre-commit hook demands an MPL SPDX + owner header on every staged .ex/.md — exactly what wrongly contaminated these third-party files. The hook should exclude demo/deps/. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
… a behaviour gate SEC-1 (SnifIsolation.agda): wire confidentiality into the operational theorem (deniability re-derived over the run via run-deniable/fault-via-observe + a two-distinct-secret SecretWitness), model the real 6-origin error taxonomy (TrapOrigin guestFault/hostBudget/preExec + a call front-end + PreExecWitness), and add a non-trivial-Alive recovery witness (PartialAlive). All mutation-confirmed load-bearing by a 4-skeptic adversarial re-audit (--safe --without-K, every targeted mutation rejected). ABI-7: BufferAbi.idr models all 7 buffer_abi exports (multi-value/void-faithful WasmSig), raising gated ABI coverage to 15/20 Zig sites; abi_conformance.py is now guest-aware. CI-1: conformance runs as a CI job in proofs.yml. GAP-1b: snif_metamorphic_test.exs — dep-free metamorphic relations over the scalar kernels (found + corrected the checked_add wrapping-vs-name misnomer). Reconcile: ffi rsr-template marked scaffold; PROOF-NEEDS.md rendered; the two Rust guest trees documented as deliberate. Docs (PROOF-STATUS/README/CHANGELOG) reconciled to the verified state. Gate green this commit: just proof-check-all (exit 0), just abi-conformance (15 specs), mix test (30/30, OTP 25). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Point-in-time, jointly-signed attestation per the estate AFFIRMATION standard (the README/EXPLAINME/AFFIRMATION trio). Every claim ground-truthed by running the tools this session against the committed anchor a82bb31 (its parent == the anchor SHA): proof-check-all exit 0 (10 gated artifacts), abi-conformance 15/15, mix test 30/30 (OTP 25). Honest gaps stated: Safer-not-Safe (SEC-1-TCB trusted), ABI-7 15/20, GAP-1b scalar-only. Dual-licensed MPL-2.0 OR CC-BY-SA-4.0. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
… not a fix) Add docs/templates/contractiles/bust/Bustfile.a2ml — a 'bust' (= broken, the slang) contract with a disjoint '## Near-Hit Cases' recognition ledger. Records zig-0.15.2-opaque-with-fields-template-rot: the rsr-template src/interface/ffi uses pre-0.15 Zig (opaque-with-fields + c_allocator) that 0.15.2 correctly rejects, but it does NOT bite here — the template is unrendered dead scaffold wired into no build/gate, and the live guests compile clean. By-design type discipline, not a Zig regression; recognition, not a fix-queue item (the same pattern is genuinely bust in typed-wasm). Seeds two real Failure Modes (ReleaseFast silent-wrong-answers; wasmex/ABI-drift load failure). Extend the main.zig SCAFFOLD banner with the same Zig-0.15.2 note + a pointer to the Bustfile near-hit.

… wrapping misnomer (#40) ## Summary Follow-up to #39. `checked_add` was a wrapping `a +% b` despite its name — the GAP-1b metamorphic gate surfaced the misnomer in #39. This makes it a genuinely **checked** add. - **zig** (`safe_nif.zig`): `@addWithOverflow` + `unreachable` → overflow **traps** (WASM `unreachable`, all build modes, like `crash_unreachable`) → wasmex `{:error, _}`, BEAM survives; a non-overflowing add returns the **exact sum**. Signature unchanged. - **metamorphic gate** (`snif_metamorphic_test.exs`): flipped from the `wrap32` ring oracle to *non-overflow = exact sum / overflow = `{:error,_}`*; added the boundary-trap test. - **bench + docs**: fixed the stale "intentional wrap" row + comments in `benches/snif_eval.sh`; reconciled `CHANGELOG` + `PROOF-STATUS` GAP-1b. The `AFFIRMATION.adoc` (merged in #39, anchored to `a82bb31`) is intentionally **not** edited — at that anchor `checked_add` genuinely *was* wrapping, and the affirmation is a frozen, signed snapshot. A fresh affirmation can be stamped at a later commit if desired. ## Verification (green this commit) - `just proof-check-all` → exit 0 (signature-only ABI unaffected) - `just abi-conformance` → 15/15 (signature unchanged) - `mix test` → 30/30 (OTP 25); metamorphic 9/9 under the new checked semantics - Zig 0.15.2 compiles `@addWithOverflow` + tuple indexing + `unreachable` 🤖 Generated with [Claude Code](https://claude.com/claude-code)

…formance required) (#41) ## Summary A **fresh** AFFIRMATION snapshot, re-stamped at `main` HEAD after #39 + #40. The previous affirmation (merged in #39) is anchored to `a82bb31`, where `checked_add` genuinely *was* a wrapping misnomer — that frozen snapshot was left intact. This refresh re-anchors to `70d9f65` and folds in what changed since: - `checked_add` finding **RESOLVED** — now genuinely checked (overflow traps); the metamorphic oracle is the checked (not wrapping) one. - `abi-conformance` is now a **required** status check on `main`. - Re-anchored to `70d9f65`; **parent == anchor**. ## Verification (re-run on `main` this commit, 2026-06-16T15:03:15Z) - `just proof-check-all` → exit 0 (10 gated artifacts) - `just abi-conformance` → 15/15 (2 guests) - `mix test` → 30/30 (OTP 25) 🤖 Generated with [Claude Code](https://claude.com/claude-code)

This branch sits on the owner's pre-existing local commit 913d141 ("restore third-party vendored deps to pristine upstream licences") — the branch HEAD when this work began, not yet on
main. It is a licence commit and the owner's own work; included here with explicit owner permission for this PR, called out openly. Rebasing it out was avoided deliberately because it would rewritea82bb31and break the AFFIRMATION's anchor.Owner follow-ups (not in this PR)
