[Unreleased]

[2.5.5] — 2026-06-02

Release of the v2.5.5 cohort that landed across 11 PRs in panic-attack + wiki + gitbot-fleet on 2026-06-02 PM. Tagged 2026-06-02 PM-evening.

Added (2026-06-02 PM) — v2.5.5 context-awareness cohort + v3.0.0 Chapel→VeriSimDB push + PROOF-PROGRAMME

Eight PRs landed in one cohort closing the v2.5.5 ROADMAP section, a v3.0.0 item, and opening the first proof slice of the new PROOF-PROGRAMME.

v2.5.5 — Attack Surface Widening (false-positive reduction)

• test_context foundation (#102): new src/test_context.rs module with cross-language test-path classification (Rust / Python / Go / JavaScript / Julia / Zig / Elixir / docs-examples). New WeakPoint.test_context: Option<TestContext> field (Production / TestOnly / Doc) plumbed through 137 construction sites. Content-based promotion via use ExUnit.Case / unittest.TestCase / pytest.fixture / @testset markers.
• comment_marker inline suppression (#105): new src/comment_marker.rs module recognising // panic-attack: accepted [- reason] on the same or preceding line. Cross-language comment leaders: // mid-line for C-family; # / -- / ; / % / /// / //! start-of-line for Python/Haskell/Lisp/Erlang/Rust-doc/Rust-inner-doc. String-literal aware. Shebang #! excluded.
• ffi_kind subtyping (#106): new src/ffi_kind.rs module subtyping WeakPointCategory::UnsafeFFI (PA013) into BuildSystem / RuntimeAbi / TestMock / Unknown. classify_by_path distinguishes build.zig / build.rs (BuildSystem, audit-accepted by default) from bindings/ / ffi/ / sys/ / cdef.zig (RuntimeAbi, audit-significant) from tests/mocks/ / tests/stubs/ (TestMock, also audit-accepted). New is_audited_boundary(audit_text, file_path) parses audits/audit-ffi-unsafe.md ## Approved boundaries markdown.
• jit_context classifier (#107): new src/jit_context.rs module classifying JIT frameworks — Cranelift / Llvm / Wasm / Javascript / None. Factors existing inline Cranelift detection at analyzer.rs:1117..1129 into reusable surface. transmute_targets_fn_ptr made tolerant of = unsafe { ... transmute(..) } wrappers.
• Phase 2 analyzer wire-up (#110): new apply_v255_context_suppression(&mut report) runs after the kanren-based rule pass and (a) marker-flips WeakPoint.suppressed = true when panic-attack: accepted is on or above the line, (b) auto-suppresses PanicPath in TestOnly/Doc context, (c) auto-suppresses UnsafeFFI in BuildSystem/TestMock context. Sets test_context metadata on every finding with a known file path.

v3.0.0 — Distributed Scanning (HTTP push from Chapel)

• panic-attack verisim-push <hexad> subcommand (#108): new Commands::VerisimPush gated on the http Cargo feature. Reads a JSON hexad (typically what Chapel takeSnapshot just wrote), POSTs to $VERISIMDB_URL (default http://localhost:8080) via the existing storage::push_hexad_http_with_retry. --fallback-dir writes a JSON copy on HTTP failure for offline replay.
• Chapel takeSnapshot overload (#108): new 6-arg form accepting verisimPushUrl + panicAttackBin parameters. Spawns panic-attack verisim-push --url <url> --retry <hexad> after local hexad write. Local writes remain authoritative; push is additive. Closes the [ ] ROADMAP item.

PROOF-PROGRAMME — first-principles soundness

• PROOF-PROGRAMME.md (#104): 3-layer landscape (Surface / Engine / Persistence) covering all 25 PA-code soundness proofs + miniKanren correctness + bridge reachability + attestation chain unforgeability. 9-phase sequencing (~16 weeks). Identifies proven cross-fit candidates: only SafePath + SafeUrl qualify as port-to-Rust (perf-neutral, semantic-equivalent); SafeJson / SafeRegex / SafeDateTime / SafeCommand / SafeEnv / SafeUUID marked skip (already total / semantic mismatch).
• Layer 1.0 partial (#111): new src/abi/Stripping.idr Qed-closing the foundation lemmas for line-comment stripping — stripBodyProducesStrippedShape (every body output satisfies IsStrippedBody) + base cases of stripLineCommentsIdempotent (empty + non-slash-headed input). Open: the slash-slash inductive closure stripIsIdentityOnStrippedBody (recorded as the next Layer-1.0 slice in PROOF-NEEDS.md).

Changed (2026-06-02) — truthfulness audit (humans + machines)

• README badge + Status block corrected: 402 → 782 runnable tests (per cargo test --release -- --list; the underlying 539 #[test] annotations expand via doctests + integration tiers). The badge had not tracked actual count for several releases. Wiki Home was 282+.
• chapel-ci chapel-multilocale gate robustified (#100 collateral): pinned CHPL_UNWIND=system explicitly + moved libunwind-dev install to always-run (not gated on cache-hit). On cache-hit runs without libunwind-dev, chpl auto-inferred CHPL_UNWIND=bundled and aborted with "no runtime for bundled" because the cached runtime was built with system. Cache-gen counter bumped v1 → v2 to discard the inconsistent cache. Fifth Chapel-2.8.0 sharp edge from #99 Wave 2.
• ROADMAP v2.2.0: downgraded "Per-project VeriSimDB instance: deploy/panic-attack/fly.toml for verisim-panic-api" from [x] to [~] — the API runs but the toml file is NOT in this repo (lives in the verisimdb deployment tree). The [x] checkbox previously pointed at a path that didn't exist on main.
• ROADMAP front matter + Wiki Home: "500+ repositories" replaced with the empirically verifiable "303-repo hyperpolymath estate (2026-04-12)" — the number that appears in docs/mass-panic-fnirs-paper.adoc Table I.
• chapel/README.md: 5× softening of "~5–15% slower" to "(UNMEASURED ESTIMATE)" with explicit link to panic-attack#87 Wave-3 followup for the actual benchmark.
• README Status block + Wiki Home: noted that the 25 canonical PA codes correspond to 26 WeakPointCategory enum variants — PA001 ⇒ UncheckedAllocation and PA001b ⇒ UnboundedAllocation share the same canonical SARIF rule for taxonomy purposes (see src/report/sarif.rs).

Added (2026-06-01) — Chapel Wave 2: single-host multilocale gate

• chapel-multilocale CI gate (#99, closes #87 option A): adds a 7th strict chapel-ci job that builds Chapel 2.8.0 from source with CHPL_COMM=gasnet + CHPL_COMM_SUBSTRATE=smp + CHPL_LAUNCHER=smp, caches $CHPL_HOME (actions/cache@v4, stable key with manual CHAPEL_MULTILOCALE_CACHE_GEN invalidation counter; cold build ~30-40 min, warm restore ~30s for 7 days), runs mass-panic --numLocales=2 against a synthetic 2-repo corpus, and greps the emitted system-image-*.json for both repo names to prove cross-locale aggregation actually executed. The Wave 1 binary .deb install path is single-locale only; this gate closes the gap.
• Aggregator chapel-ci-gate updated to wait on the 7th job and to surface it as multilocale=<result> in the gate summary.
• Wave 3 (gasnet/ofi over a real NIC across cluster nodes) and the ~50-repo "~5-15% slower" benchmark from chapel/README.md remain parked — both need a beefier or self-hosted runner to be meaningful.

Fixed (2026-06-01) — baseline-red corrective maintenance

• Dogfood Gate A2ML validation restored (#94, #97): bumped hyperpolymath/a2ml-validate-action from 59145c7d to 6bff6ec to pick up s-expression-form identity/version recognition (upstream PR #26); relocated docs/campaigns/2026-05-26.a2ml to .machine_readable/campaigns/ so it inherits the structural-identity exemption (the file's own header describes it as "machine-readable A2ML form").
• Governance Trusted-base reduction policy restored (#94): added .trusted-base-ignore exemption for src/assail/analyzer.rs — the file IS the scanner that defines the escape-hatch patterns, so its literal references to them are by design.
• Secret Scanner rust-secrets false-positive cleared (#94): refactored RE_HARDCODED_SECRET regex construction via concat! to split detector keywords across source-string boundaries (the literal password keyword in the source was self-flagging).
• Rust CI reusable SHA bumped past standards#334 (#97) — caller now resolves the ${{ }}-wrapped job-level if: fix and unblocks the rust-ci.yml wrapper that was reporting 0-second parse failures (root cause documented at standards#322).
• rsr-template scaffolding gaps filled (#96): LICENSE flipped from AGPL-3.0 body to MPL-2.0 (matching SPDX headers + Cargo.toml + README.adoc); CODE_OF_CONDUCT.md placeholders instantiated ({{CONDUCT_EMAIL}} → j.d.a.jewell@open.ac.uk, {{CONDUCT_TEAM}} → panic-attack maintainers, {{RESPONSE_TIME}} → 48 hours, language-bridges → panic-attack); bug_report/feature_request issue templates Rust-toolchain-aware; empty custom.md removed; SECURITY.md version table updated from 0.2.x to 2.5.x.

Changed (2026-06-01)

• Dependabot rust-minor group bumps (#93): log 0.4.29 → 0.4.30, eframe minor update.

Added (2026-05-30) — issue #33 closure

• VeriSimDB hexad persistence complete (issue #33 S1–S3) — per-finding hexads, campaign state lifecycle, and S-expression query DSL all shipped:
  • S1: per-finding hexad emission gated by PANIC_ATTACK_STORE_FINDING_HEXADS=1 (src/storage/mod.rs :: build_finding_hexads, subject format finding:<repo>:<file>:<line>:<category>).
  • S2: panic-attack campaign subcommand (register-pr, dismiss, status, poll) drives finding lifecycle with state transitions persisted as campaign hexads. poll performs GitHub PR state transitions (open → pr-filed → pr-merged / pr-closed).
  • S3: panic-attack query <expr> evaluates a small S-expression language over the persisted hexads. Heads: category, rule-id, severity, repo, file, pr-state, since, crosslang, diff, and, or, not.
• Query parser: (diff :since :category ...) head + inline :keyword VALUE kwargs on every unary head (src/query/mod.rs). The issue body's three literal example expressions now parse verbatim:
  • (crosslang :from FFI :to ProofDrift) — already worked.
  • (category PA001 :severity Critical :pr-state nil) — now parses as (and (rule-id PA001) (severity Critical) (pr-state nil)), with PA-prefixed values on category auto-routed to rule-id so the query actually matches findings.
  • (diff :since 2026-04-12 :category PA022) — new diff head is keyword-only sugar for an (and ...) over its kwarg pairs. Inline kwargs are accepted on category, rule-id, severity, repo, file, pr-state, and since — adding a :keyword VALUE after the positional value desugars to (and (head positional) (kw value) ...). Behaviour unchanged for existing query expressions; 12 new unit tests.

Added (2026-04-18)

• User-classification registry (assail::UserClassification, load_user_classifications, apply_user_classifications): panic-attack now reads an optional project-local classification file at every assail pass and flips matching findings to suppressed = true after the kanren structural-suppression pass. Two lookup paths:
  • <project_root>/audits/assail-classifications.a2ml (preferred)
  • <project_root>/.panic-attack-classifications.a2ml (fallback) File format is a simple A2ML S-expression with (classification (file …) (category …) (audit …) (rationale …)) blocks; ;; line comments ignored. The registry pattern lets repositories record audited findings out-of-band from the source under scan so a PR adding a new unsafe block cannot self-suppress without a reviewable companion edit to the registry.
• Rocq scaffold classifier (analyze_coq + count_rocq_unverified_postulates + is_rocq_abstraction_parameter): the Rocq detector no longer counts Section-scoped Variable / Hypothesis / Parameter declarations (they discharge at End Section) and classifies module-level Parameter declarations by stated type: carrier types (Type, Set), decidability witnesses (forall _, { _ = _ } + { _ <> _ }), and function types with a concrete non-Prop codomain are treated as abstraction parameters. Prop-valued declarations (classical excluded-middle, choice, unresolved theorem statements) remain counted. Removes the false-positive stream that surfaced on every canonical-proof-suite scaffold.

Changed

• Suppression pipeline: analyze() and analyze_verbose() now chain apply_suppression → apply_user_classifications in that order; the explicit post-analyze calls in assail::analyze and assail::analyze_verbose at the module boundary are retained for API-contract clarity but are no-ops when an Analyzer pass has already run.
• Rocq test coverage: 12 new unit tests across analyzer.rs (Section-scoped Variables / module-level Type carriers / decidable equality / concrete-codomain functions / Prop-valued axioms / missing type annotation / full scaffold shape — 7 tests) and mod.rs (missing-registry / single-entry / multiple-entry / comment handling / end-to-end suppression-flip — 5 tests).

Verified

• 007 canonical-proof-suite scan: active finding count 8 → 0 (the 6 scaffold ProofDrifts via the detector enhancement, the 2 zig_bridge.rs UnsafeCode findings via the classification registry pointing at audits/audit-ffi-unsafe.md §1). No in-source suppression markers added to either repo.

[2.5.0] - 2026-04-12

Added

• InputBoundary category (PA024): New weak point category detecting unguarded structured-data parsing at trust boundaries.
  • Rust: serde_cbor::from_slice/from_reader, ciborium::de::from_reader, rmp_serde::from_slice/from_read — CBOR/MessagePack deserialization without a validation layer (Medium). All five crate patterns flagged.
  • JavaScript/ReScript: JSON.parse( in files without any try/catch context (High). Files that do wrap their JSON.parse in try/catch are not flagged.
  • Julia: JSON3.read( and JSON.parse( without error handling context (High).
  • Taint tracking from external reads to trust-sensitive sinks deferred to kanren phase.
  • A2ML boundary detection deferred — requires cross-file analysis.
• PA024 → panicbot: InputBoundary mapped to static-analysis/input-boundary, 0.72 confidence, Control tier, Partial fixability.
• MutationGap category (PA025): New weak point category detecting mutation and chaos coverage gaps in test suites.
  • Rust (project-level): Tests present (mod tests / #[cfg(test)]) but no cargo-mutants config in Cargo.toml or mutants.toml — mutation tooling absent (Low).
  • Julia (per-file): @testset blocks where every @test is a type-check assertion (@test … isa …) with no value assertions — no assertion diversity (Medium).
  • Elixir (per-file): Test files using ExUnit.Case without importing ExUnitProperties or StreamData for property-based testing (Low).
  • Coverage-plus-mutation-score check deferred — requires runtime coverage data.
• PA025 → panicbot: MutationGap mapped to static-analysis/mutation-gap, 0.80 confidence, Substitute tier, Partial fixability.
• Idris2 ABI completeness: PatternCompleteness.idr updated — InputBoundary (Rust/JS/Julia) and MutationGap (Rust/Julia/Elixir) added to WPCategory with detectorsFor entries.

Changed

• Category count: 23 → 25 (added InputBoundary, MutationGap)
• v2.5.0 milestone: All tractable items complete. Two deferred items each for input_boundary (taint+A2ML) and mutation (coverage-score), and three for crypto_misuse (key-reuse, nonce-reuse, sig-verify) marked as statically undetectable or requiring runtime data.

[2.3.0] - 2026-04-12

Added

• CryptoMisuse category (PA022): New weak point category detecting cryptographic primitive misuse across five languages. Context-window heuristic (±200 chars) restricts MD5/SHA-1 findings to security-sensitive usage — MD5 for file checksums is not flagged.
  • Rust: md5::compute/Md5::new and sha1::Sha1/Sha1::new in security context (High); == comparison on secret/password/token/key variables (Critical — timing attack).
  • Python: hashlib.md5()/hashlib.sha1() in security context (High); == on secret-named variables — use hmac.compare_digest() instead (Critical).
  • JavaScript: crypto.createHash('md5') and crypto.createHash('sha1') (High); crypto.createHash('sha256') is fine and not flagged.
  • Go: md5.New()/md5.Sum() and sha1.New()/sha1.Sum() in security context (High).
  • Elixir: :crypto.hash(:md5, ...) and :crypto.hash(:sha, ...) (High); :crypto.mac(:hmac, :sha, ...) is acceptable (HMAC-SHA1 is not broken) and not flagged.
  • Key-reuse and nonce-reuse deferred — not reliably detectable statically.
• has_security_context() helper: Module-level helper function checks ±200 char window around a pattern match for security vocabulary (password, secret, token, auth, key, credential, hash, sign, verify, encrypt) to reduce false positives on benign MD5/SHA-1 use.
• PA022 → panicbot: CryptoMisuse mapped to fleet category static-analysis/crypto-misuse with 0.75 confidence, Eliminate tier, Partial fixability. Confidence is honest — the context window has a modest false-positive rate when security vocabulary appears for unrelated reasons.
• Idris2 ABI completeness: PatternCompleteness.idr updated — CryptoMisuse added to WPCategory with detectorsFor covering Rust, Python, JavaScript, Go, Elixir.

[2.2.0] - 2026-04-12

Added

• SupplyChain category (PA023): New weak point category detecting dependency and build integrity gaps: Cargo.toml git dependencies without rev =, absent Cargo.lock for library/binary crates, Julia Manifest.toml without git-tree-sha1 hash entries, flake.nix inputs without narHash, and deno.json import map entries without a version pin. Project-level manifest checks run as a synthesis stage after file analysis. Confidence 0.85 — these are explicit manifest/config patterns with low false-positive rate.
• PA023 → panicbot: SupplyChain mapped to fleet category static-analysis/supply-chain with 0.85 confidence, Eliminate tier, fixable (adding pins resolves the finding).
• Idris2 ABI completeness: PatternCompleteness.idr updated — SupplyChain added to WPCategory with detectorsFor covering Rust, Julia, Nix, JavaScript.

Changed

• Category count: 22 → 23 (added SupplyChain)

[2.1.0] - 2026-04-12

Added

• ProofDrift category (PA021): New weak point category detecting formal verification drift across all proof assistant languages. Catches banned proof escape hatches (sorry, Admitted, believe_me, oops, trustMe, assert_total, %partial, {-# TERMINATING #-}) and Julia mirror files substituting @test x isa Y or # sorry comments for formal proofs. Confidence 0.92 — proof escape hatches have essentially no false positives in their file types.
• Isabelle/HOL language support: .thy files parsed with analyze_isabelle() detecting sorry, oops, and axiomatization as ProofDrift findings.
• Coq/Rocq language support: .v files parsed with analyze_coq() detecting Admitted, admit tactic, Axiom/Parameter declarations, and Obj.magic in extraction artifacts.
• Isabelle + Coq dispatch: Both new languages wired into analyze_inner() dispatch.
• Lean4 ProofDrift upgrade: sorry upgraded from UnsafeCode → ProofDrift (Critical). Added unsafeNativeIO/unsafeBaseIO as ProofDrift (IO discipline bypass).
• Agda ProofDrift upgrade: trustMe/primTrustMe upgraded to ProofDrift (Critical). Added {-# TERMINATING #-}, {-# NON_TERMINATING #-}, bare postulate as ProofDrift.
• Idris2 ProofDrift upgrade: believe_me already ProofDrift; added assert_total (High) and %partial (Medium) as ProofDrift findings.
• Julia mirror detection: # sorry, # TODO: prove, # admitted comments and @test x isa Y patterns (no value check) flagged as ProofDrift in Julia files.
• FP suppression wiring: apply_suppression() now runs on every scan, marking weak points suppressed: true when logic engine finds defensive-pattern context. Suppressed items stay in report for audit transparency; filtered by panicbot and CI gates.
• PA021 → panicbot: ProofDrift mapped to fleet category static-analysis/proof-drift with 0.92 confidence and Control tier.
• Idris2 ABI completeness: PatternCompleteness.idr updated — Isabelle, Coq added to Lang enum; ProofDrift added to WPCategory with detectorsFor covering all new languages.
• Hypatia integration: JSON AssailReport consumed by Hypatia Elixir rules. Logtalk export removed 2026-04-12.

Changed

• Language count: 47 → 49 (added Isabelle, Coq)
• Category count: 20 → 21 (added ProofDrift)
• Verbose output: Two views — filtered (active, what CI sees) and unfiltered (total, audit transparency) with explicit labelling of what each count means.

[2.0.0+] - 2026-03-23

Fixed

• A2ML parser: Now handles TOML-like format (key = "value") in addition to S-expression format
• Manifest lookup: Tries 0-AI-MANIFEST.a2ml first before falling back to AI.a2ml
• Language detection: Skips external_corpora/, third_party/, and corpus/ directories to avoid false positives from vendored or reference text

• Justfile: build, test, readiness, readiness-summary, clean, install, dogfood, lint recipes
• Manifest-first framework detection: Detects frameworks from Cargo.toml, mix.exs, package.json etc. instead of source scanning (eliminates false positives)

Fixed

• All compiler warnings: 0 warnings in both release and test builds
• Test count: 269 tests (up from ~30), 0 failures

Changed
