Changelog

All notable changes to ECHIDNA will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Added — structural cross-prover identity keys, 2026-10-22

• src/rust/corpus/canonical.rs — normalises a declaration’s type into a nameless prefix term (variables renamed v0, v1, …, module qualifiers dropped, operator spellings and binder keywords canonicalised, sorts mapped to NAT/INT/TYPE/…, ascriptions unwrapped) and hashes it with SHA-256 under scheme dk-shape-v1. No dictionary and no per-prover naming convention is consulted.

• DeclGraph gains cross_prover_identity_key, cross_prover_skeleton_key (binders and sorts erased — the tier-2 join for Isabelle and Why3), identity_scheme and canonical_type. All are #[serde(default)], so existing octad files still load; cross_prover_id (the name-tail hash) is still emitted for compatibility.

• GraphPayload (VeriSim bridge) and QueryResultEntry (VCL-UT) carry the structural key through to consumers.

• echidna corpus identity <pattern> — groups declarations by structural key, with --skeleton (print the tier-2 key) and --cross-only (only groups spanning several adapters).

Changed — structural 256-dim Vector octad, 2026-10-22

• The default embedder is now StructuralEmbedder: 1–3-grams of the canonical type atoms hashed into 256 buckets (L2-normalised, model echidna-corpus-structural-v2). corpus near canonicalises the query first, so a query written in one prover’s syntax retrieves entries written in another’s.

• HashEmbedder (32-dim, echidna-corpus-hash-v1) remains available as Corpus::compute_embeddings_legacy for GNN FEATURE_DIM parity and for replaying octads written before this change. The capnp embedder / embedder_dim fields carry both, and consumers must compare them before comparing vectors.

• Supersedes the embedder half of D6 in docs/decisions/2026-04-28-corpus-and-design-search.adoc; the decision record is annotated in place.

Added — corpus adapters for the estate’s own TCB languages, 2026-10-22

• src/rust/corpus/spark_ada.rs — Ada/SPARK adapter (*.ads / *.adb). Extracts packages, with/use clauses, subprograms with their Pre/Post/Contract_Cases/Global/Depends aspects, and the GNATprove escape hatches: pragma Assume (and the old --# assume form) is reported as a postulate, plus pragma Annotate proof disabling, pragma Suppress, Unchecked_Conversion, pragma Import and SPARK_Mode => Off. Recognises the sparklib Lemma_* + Ghost lemma convention as sparklib:lemma so reusable lemmas are separable from executable subprograms. Spec and body are paired across files into one entry (unambiguous pairs only).

• src/rust/corpus/creusot.rs — Rust/Creusot adapter (*.rs). Folds #[requires], #[ensures], #[invariant], #[variant], #[logic], #[predicate] and #[cfg(creusot)] into the entry’s statement, and tags pearlite!, proof_assert!, snapshot!, unsafe, transmute and extern "C". #[trusted] is reported as a postulate, because Creusot accepts the contract and skips the body. #[test] / #[cfg(test)] items are excluded: a corpus of proofs should not be dominated by test functions.

• src/rust/corpus/profile.rs + data/corpus-profiles/hyperpolymath-estate.toml — the hyperpolymath_estate profile: every repository’s src/abi Idris2 tree (a name = "*" rule, so new repos are picked up without a manifest change) plus the five Agda type libraries (echo-types, epistemic-types, secret-types, tropical-types, choreographic-types). Sub-trees are indexed by their own adapters, then merged with repo:: name prefixes and repo: / layer: module tags. ECHIDNA_ESTATE_MANIFEST overrides the manifest path.

• Corpus::reindex_links() — split out of reindex() so a merge can rebuild the lookup maps without re-running discipline detection under the merging adapter’s name.

• crates/echidna-core-creusot/src/estate_layers.rs — Creusot-annotated layer classification (PO-L1..L5): totality, partition, and the checkable form of "every ABI is Idris2". Stated, not proved, like the rest of that crate; the stable-Rust tests mirror every obligation.

• _verification_systems.toml 8 rows for the syntax the new adapters detect (`+pragma_assume, `contract_cases, spark_mode, ghost_lemma, trusted_attribute, pearlite, proof_assert, variant_clause), so the semantic layer can resolve what the indexer reports.

• Corpus adapters: 17 → 20. Open backlog re-ordered: iris.rs and tlaps.rs to the top (separation logic for the Zig/Rust layers; temporal proofs for the Elixir/OTP and SNIF layers), alphaproof.rs and naproche.rs to the bottom (no published corpus or file format, and no estate vocabulary).

Added — verification vocabulary 2026-10-22

• data/synonyms/_verification_systems.toml (665 rows): the first cross-prover dictionary aimed at program verification rather than undergraduate pure mathematics. Sections: bitvectors and machine integers, memory layout and ABI, ownership and slicing, separation logic and region framing, contracts and proof obligations, termination measures, refinement and semantics, resource algebras (dioid / tropical / antichain / fixpoint), information flow and epistemic vocabulary, concurrency, and the estate layer boundaries. Loaded as CrossProverDicts::verification_systems (Rust) and SaturationSynonyms.load_verification_systems (Julia).

• _msc2020.toml 87 → 181 codes. 68Qxx (26 codes) and 68Nxx (10 codes) are now complete; 03B/03C/03D/03F cover logic, computability and proof theory; 68M/68P/68T/68V/68W and 06B35 cover the systems and proof assistant ring. Nineteen pre-existing rows had MSC2010 or transferred wording and are repaired in place, with a note naming the MSC2020 code (03B15 → 03B16/03B38, 68T15 → 68V15, 68V05/68V25/ 68V30/68V35 re-pointed to their current meanings).

• Consumer wiring: corpus crossquery now searches the cross-prover dictionaries as well as the per-prover tables, so crossquery frame-rule, crossquery estate-snif or crossquery 68Q60 resolve; --provers-only restores the old scope. CrossProverDicts::tables()/len() and SynonymTable::merge_cross_prover_dicts() added. The Julia training launcher pre-loads all five dictionaries at launch.

• idris2.toml 6 → 26 rows: Fin, Bits8/16/32/64, Int8..64, Vect, So, LTE, Dec, cast, totality annotations, %foreign, export, Prim__, Ptr, IO, Ref, multiplicities and erasure — the vocabulary the Idris2 ABI layer is written in.

• More MSC repairs: 18N40, 18G80, 18D05 and 14F08 corrected against zbMATH (18N40 is model categories, not HoTT; 18G80 is derived categories, not infinity-categories; 18D05 is MSC2010-only and moved to 18N10). Added 18G35, 18M05, 18N45 and 18N60; MSC total 181.

• Doc mirrors: the wiki pages named a SynonymTable::with_msc2020() API that never existed; they now use the real loader. Wiki/architecture pages updated to the five-dictionary reality.

• Estate language policy recorded in data/synonyms/README.adoc: ABIs in Idris2, APIs and FFIs in Zig, BEAM native boundaries as SNIFs (not bare NIFs), Rust/Creusot for the Rust layer, Julia and Chapel for their layers, and no Python anywhere in the tree.

Added — arbitration 2026-10-14 (ECH-05)

• Fidelity-levelled arbitration: ProverAttempt carries FidelityEvidence (KernelTranslation / DeclaredCorrespondence / None) and ArbitratedVerdict gains level (belief / epi / sound), retracted and warranted_term. sound needs every fused attempt to be a kernel-checked translation to one exchange-layer term (exchange::term_hash); a synonym collision stays belief however many backends agree. ResultArbiter::retract marks a backend unsound and lowers every verdict that rested on it. Numeric fusion is unchanged: tests/arbitration_regression_test.rs replays the pre-change numbers. Dispatch attaches no evidence yet, so dispatched verdicts are belief.

• EchidnaABI.Arbitration (Idris2): the three-level verdict as a closed sum whose Sound constructor carries the hash-equality proofs, with the classifier and its properties; tests/abi/{accept,reject} fixtures checked by scripts/abi-fixtures.sh in idris2-abi-ci.yml.

Added — integrations 2026-10-05

• echidna prove --output json: prints exactly one echidna.prove.result/1 object (JCS-canonical I-JSON) on stdout, logs to stderr. Statuses verified / failed / error / timeout / unknown, mapped from ProverOutcome; trust.confidence is null unless receipt-backed. Human output stays the default. See docs/PROVE-RESULT-CONTRACT.adoc.

• echidna-core 0.2.0 is consumable by clients (echidnabot, proof-burrower): adds ProverKind (moved from echidna::provers, re-exported there, no source change for ECHIDNA), the echidna.prove.result/1 type with a strict parser, and the trust kernel as echidna_core::trust. Git-dependency recipe and stability policy in crates/echidna-core/README.adoc.

• ffi/zig builds and is tested in CI (zig-ffi-ci.yml, Zig 0.15.2): it previously compiled on no Zig release. Pure Zig (page allocator, no libc); the estate unified-api-adapter purity check (hyperpolymath/cicd-suite) runs on every PR.

Fixed — integrations 2026-10-05

• ci(chapel): build the Zig FFI with -Dcpu=baseline; the artifact runs on a different runner, and native-CPU code crashed there with SIGILL in "Rust Build with Chapel Feature".

• ci(rust): check, clippy and test now run with --workspace; before, only the root package was tested, so echidna-core and the trust kernel tests never ran in CI.

• abi: EchidnaABI.Gnn and EchidnaABI.TacticRecord now declare %default total (both already type-check total).

• docs(creusot): CREUSOT-SETUP.adoc no longer claims the Creusot job is a hard gate or that milestones 8c-M1..M3 are done; it records why Creusot does not run in CI.

Added — governance 2026-10-09

• echidna_chora.deed at the repo root: the first deed under the estate one-deed-per-repo doctrine (standards#837), translated from CLADE.a2ml (family 1) and ECOSYSTEM.a2ml (family 2) per the standards 1-formats/deed/mappings/ frame, following the proof-burrower_chora.deed precedent; clade names verbatim from the gv-clade-index taxonomy seed; passes the normative deed.abnf validator. The .a2ml descriptiles stay until their consumers move; identity/status edits touch both surfaces until then (noted in the deed header).

Fixed — governance 2026-10-09

• 0-AI-MANIFEST.a2ml: full-version was frozen at a stale 1.x value; it now tracks Cargo.toml. The UI runtime line reads Bun (Deno was banned estate-wide 2026-09-22; JS-RUNTIME-POLICY), and the deed is listed under [canonical-locations].

• .machine_readable/descriptiles/STATE.a2ml: refreshed past the 2026-10-05 integrations wave and recorded the deed baseline (session protocol).

Changed

• Licence: AGPL-3.0-or-later → MPL-2.0 for code and the specification surface, CC-BY-SA-4.0 for documentation (owner ruling D262, 2026-10-01). echidna-playground/ stays MPL-2.0, untouched. LICENSE is now the verbatim Mozilla text; NOTICE, .reuse/dep5, the crate manifests, build/guix.scm, README, CLAUDE.md, the wiki and docs/DEBT.adoc record the re-ruling. The .a2ml manifests keep their AGPL headers until their .deed conversion, so LICENSES/AGPL-3.0-or-later.txt stays until then.

Fixed

• ci(chapel): pin runs-on to ubuntu-22.04 for Chapel 2.8.0 libclang-cpp.so.14 ABI compatibility (#183). Chapel 2.8.0’s debian package is built against LLVM-14 / Ubuntu 22.04; on Ubuntu 24.04 (ubuntu-latest) apt resolves the unmet dependency with libclang-cpp-18, leaving chpl unable to load. Also switched install to apt-get install -y /tmp/chapel.deb so libclang-cpp14 / libllvm14 are resolved declaratively in one pass.

Added — Saturation campaign 2026-06-01

Branch prover-corpus-saturation (commits f73ee00..cb8caff). Owner-directed marginal-benefit push across corpus, vocabulary, arbitration, exchange, and wire-schema surfaces. See docs/decisions/2026-06-01-saturation-campaign.adoc.

• 13 new corpus adapters under src/rust/corpus/ (isabelle, metamath, mizar, hol_light, hol4, dafny, why3, fstar, acl2_books, tptp, smtlib, proofnet, minif2f). Total corpus adapter coverage: 4 → 17 (4.25×). See docs/CORPUS-ADAPTERS.adoc.

• 9 new per-prover synonym TOMLs (isabelle_afp, metamath, mizar, hol_light, hol4, dafny, why3, fstar, acl2). Total: 5 → 14 per-prover tables.

• 3 cross-prover taxonomic dictionaries (underscore-prefix): _msc2020.toml (87 codes), _wordnet_math.toml (~80 lemmas), _conceptnet_seed.toml (~55 edges, offline-resilient).

• 3 new arbitration mechanisms under src/rust/verification/: bayesian_arbiter (log-odds posterior), dempster_shafer (HighConflict trip at k > 0.95), pareto_arbiter (4-axis Pareto frontier).

• 4 new exchange bridges under src/rust/exchange/: tptp, smtlib, smtcoq (stub bridge), lambdapi.

• Formal VeriSim E-R schema at docs/architecture/VERISIM-ER-SCHEMA.adoc (12 entities + 7 relationships, crosswalk Rust↔Cap’n Proto↔ClickHouse) + Cap’n Proto wire schema crates/echidna-wire/schemas/verisim_er.capnp (@0xe4dc7b1f01a06001).

• Chapel + Julia integration hooks at docs/architecture/CHAPEL-SATURATION-HOOKS.adoc
docs/architecture/JULIA-SATURATION-HOOKS.adoc (specifications only — wave3 chapel + GNN-training-trigger files deliberately untouched).

• New Julia helper modules src/julia/corpus_loader.jl
src/julia/saturation_synonyms.jl (bridge Rust corpus JSON
  saturation synonym TOMLs into the GNN training pipeline).

• Saturation campaign ADR at docs/decisions/2026-06-01-saturation-campaign.adoc.

• Handover lane doc at docs/handover/PROVER-CORPUS-SATURATION-LANE.adoc (collision-avoidance contract with wave3/161-162-bench-telemetry-corpus).

• Corpus adapter index at docs/CORPUS-ADAPTERS.adoc.

• Justfile recipes: corpus-ingest-saturation, corpus-stats-all, synonym-load-test, test-saturation, arbiter-smoke, er-schema-drift-check.

• 139 new unit tests across the saturation modules (1 ignored heuristic-limit).

Changed

• src/rust/suggest/synonyms.rs: load_all extended to 14 provers; new CrossProverDicts + load_cross_prover_dicts()
SynonymTable::merge_external().

• src/rust/corpus/mod.rs, verification/mod.rs, exchange/mod.rs: register new modules (additive).

• Module-level doc comments on corpus/mod.rs, verification/mod.rs, verisim_bridge.rs cite the new schemas
  arbiters.

Documentation

• Wiki updated (Home, Architecture, Getting-Started, Guides, FAQ, Troubleshooting) to reflect the new surface.

• README.adoc + EXPLAINME.adoc updated with new headline counts
  per-module references.

• Machine-readable metadata under .machine_readable/6a2/ (STATE / META / ECOSYSTEM / NEUROSYM) updated additively.

• 9 RSR-template substitution gaps closed in CODE_OF_CONDUCT.adoc / SECURITY.md / AUTHORS.adoc.

Verification

• cargo check --lib clean (~24s).

• cargo test --lib -- corpus:: verification::{bayesian,dempster_shafer,pareto}_arbiter exchange::{tptp,smtlib,smtcoq,lambdapi}: 139 passed, 0 failed, 1 ignored (corpus::dafny::tests::detects_datatype_and_extern — heuristic body-less-extern-method limitation).

• Zero collisions with wave3/161-162-bench-telemetry-corpus.

---

[2.3.0] - 2026-06-01

Added

• 105 ProverKind variants (exhaustive HP type-checker ecosystem).

• Updated ProverKindInjectivity.idr to prove injectivity for all 105 variants.

• Expanded Isabelle synthetic proof corpus (105 entries).

• Resolved security alerts: Binary-Artifacts (#13), rand (#11, #10), rustls-webpki (#13, #12).

• Atomic repush consolidating corpus expansion and security hardening.

[2.2.0] - 2026-04-05

Changed

• VQL → VCL + verisimdb → verisim rename (ecosystem-wide, 2026-04-05). Internal code, docs, module names, and machine-readable manifests adopt the new ecosystem terminology. verisim_bridge.rs (was verisimdb_bridge.rs), vcl_ut.rs and vcl_ut.zig (were vql_ut.*), verisim.a2ml integration manifest (was verisimdb.a2ml). GitHub URL hyperpolymath/verisimdb preserved.

Added

• F corpus* (proofs/fstar/): 5 arithmetic lemmas (AddComm, AddAssoc, MulZero, NonNeg, Refl) discharged by F*’s SMT backend.

• TPTP corpus (proofs/tptp/): 8 first-order problems for Vampire
  E Prover, with known SZS statuses.

• DIMACS corpus (proofs/dimacs/): 5 SAT/UNSAT problems for CaDiCaL + Kissat.

• Metamath seeds (proofs/metamath/tiny.mm, broken.mm): smallest valid + deliberate-fail for the run_metamath runner.

• Agda witness (proofs/agda/IdentityLaws.agda): known-good natural-number identity proofs against agda-stdlib v2.3.

• BasicTotality.idr: small totality proofs that pass idris2 --check with no external dependencies.

Fixed

• Three broken Idris2 proofs repaired (5/5 now type-check):

  • AxiomCompleteness.idr: 23× prf = impossible (invalid RHS) rewritten to Refl impossible.

  • DispatchOrdering.idr: rewritten as a minimal working proof (6-stage dispatch pipeline with LT witnesses for adjacent stages). Original had invalid constructor signatures with named args in return-type position.

  • ProverKindInjectivity.idr: replaced 48× lteSuccRight $ ... $ LTERefl chains (unification failed) with direct LTESucc (...) constructor nesting. Type signature switched from maxDiscriminant alias to literal 48 so Idris2 can unfold S ?right. Added import Data.Nat.

• Agda scoping bugs in Basic.agda, List.agda, Nat.agda, Propositional.agda: files defined datatypes inside where clauses, putting them out of scope for outer signatures. All four rewritten as clean agda-stdlib-backed proofs (5/6 .agda files now compile).

• TPTP precedence in proofs/tptp/transitivity.p: added explicit parens around (lt(X,Y) & lt(Y,Z)) before => so E Prover parses it. Now Theorem-certified by both Vampire and E Prover.

• /api/verify false-positive guard: server-level check in prove_handler and verify_handler now returns valid: false when parse_string produces an empty ProofState (no goals, theorems, definitions, axioms, or variables) on non-empty input. Partial fix for the parse+export round-trip bug documented in TEST-NEEDS.adoc. Verified live: garbage to Coq/Lean now returns valid: false (was true); real proofs unaffected.

• Isabelle prover backend de-stubbed (src/rust/provers/isabelle.rs). parse_string previously discarded its content argument and always emitted a single Term::Const("True") goal, which verify_proof then short-circuited to Ok(true) — Isabelle was never actually invoked. It now extracts the theory name and top-level theorem|lemma|corollary declarations with nested-comment-aware scanning, stashes the raw .thy content in ProofState.metadata["raw_thy_content"], and verify_proof writes that content to a unique per-invocation temp directory under the correct filename (Isabelle requires <theory_name>.thy) before invoking isabelle process -l Main -e 'use_thys ["<path>"]'.

• Stale scaffolded temp-file path in Isabelle’s fallback verification path: previously wrote echidna_verify.thy containing theory GeneratedProof, causing filename/theory-name mismatch rejection by isabelle build. Now writes GeneratedProof.thy in a unique temp dir.

Added

• strip_isabelle_comments helper for the Isabelle backend (handles nested (* ... *) blocks).

• 9 new unit tests for the Isabelle theory-header parsers (test_strip_*, test_extract_theory_name_*, test_extract_lemma_names_*) and the parse_string contract (metadata populated, goals non-trivial, context theorems enumerated, empty-theory fallback goal).

• Parser verified against a real 788-line Tropical.thy (tropical semiring formalisation): extracts theory name and all 55 theorems/lemmas.

Notes

• Deployment of this fix to echidna-nesy on Fly.io requires rebuilding the container with the isabelle binary on $PATH. Without it, verify_proof returns Ok(false) with a "Failed to run Isabelle process" context error.

• Audit of all 50 prover backends confirmed Isabelle was the only truly stubbed one. metamath.rs and typed_wasm.rs are intentionally pure-Rust in-process verifiers (no subprocess needed by design). The remaining 47 external-solver backends all spawn real solver subprocesses via Command::new.
