From b8e06df58b941ab71eded31b8ee53ab71229af5f Mon Sep 17 00:00:00 2001 From: hyperpolymath <6759885+hyperpolymath@users.noreply.github.com> Date: Thu, 22 Oct 2026 14:55:59 +0000 Subject: [PATCH 01/33] vocab: add _verification_systems dictionary and expand MSC2020 Verification vocabulary was absent from every cross-prover dictionary. _wordnet_math (81 rows) and _conceptnet_seed (53 rows) cover undergraduate and competition pure mathematics, the same shape as the ProofNet and MiniF2F adapters; 21 of 23 probe concepts (zero_extend, wrapping_add, slice_disjoint, dioid, noninterference, ...) had no entry at all. * data/synonyms/_verification_systems.toml: 657 new rows in 12 families -- bitvectors, memory layout/ABI, ownership and slicing, separation and region framing, contracts and proof obligations, termination measures, refinement/semantics, resource algebras, information flow/epistemic, concurrency, toolchains, and estate layering. * estate policy encoded in the vocabulary: Idris2 ABIs, Zig APIs and FFIs, SNIF (not bare NIF) boundaries, Rust/Creusot, Julia, Chapel; no Python. * _msc2020.toml: 87 -> 177 codes. 68Qxx (26) and 68Nxx (10) are now complete, 03B/03C/03D/03F completed, 68M/68P/68T/68V/68W and 06B35 added. FIFTEEN pre-existing rows carried MSC2010 or transferred wording (03B15, 68T15 are MSC2010-only; all four 68V rows were mislabelled; 03D03, 03F50, 06A11, 18N10 were wrong) and are repaired with notes. * wiring: CrossProverDicts::verification_systems (Rust) and SaturationSynonyms.load_verification_systems (Julia), both exported and documented; state/meta manifests and prose counts updated. * docs/reports/2026-10-22-vocabulary-recon.adoc: the recon, including the finding that the dictionaries are loaded but have no ranking consumer yet, and that '250 codes in 68Q/68N/03B70' is impossible (those sections define 37 codes in total). Validated with a local mirror of schema.ncl (Nickel is not installed in this sandbox): 19 tables, 1357 rows, 0 failures, all reject fixtures still reject. CI must still run just lexicon-check.

I re-ran the check and got 21 of 23 +probe concepts in the brief with **zero** occurrences anywhere under +`data/synonyms/` (the two hits were incidental substrings, not entries). + +The reason this is a priority is *not* that ProofNet or MiniF2F are +wrong. They are correct for what they are: ProofNet is textbook +undergraduate problems (Rudin, Munkres, Dummit-Foote) and MiniF2F is +olympiad problems. Both adapters in `src/rust/corpus/` say so in their +module docs. They should stay exactly as they are. + +The priority comes from Stage 1d of `docs/ROADMAP.adoc`: *"vocab covers +the surface [255 K; target ~1 M]"*. The repository's surface includes +`src/abi/` (Idris2), `ffi/zig/` (Zig), `spark/`, `crates/echidna-core-creusot/`, +and the Julia/Chapel layers. That surface has no semantic classes at all +today, so the cross-prover join cannot carry it. That gap is real, +load-bearing, and orthogonal to the maths corpora. + +=== One honest caveat about priority + +The dictionaries are *loaded* on every run but almost nothing *consumes* +them yet: + +[cols="1,1,3"] +|=== +| Dictionary | Loaded by | Read by a consumer? + +| `_msc2020.toml` +| `load_cross_prover_dicts` (Rust); `load_msc2020` (Julia) +| Partly — `src/julia/run_training.jl:116` pre-loads it at training launch + so TOML breakage surfaces early.

Jewell" Date: Thu, 22 Oct 2026 17:29:43 +0000 Subject: [PATCH 24/33] corpus: structural cross-prover identity keys and a 256-dim structural embedder E6 cross_prover_identity_key was the SHA-256 of a declaration's name tail, so two provers joined only when their authors happened to pick the same local name (`+-comm` vs `Nat.add_comm` vs `bvadd_comm`). It is now the SHA-256 of the *canonical shape of the type*: variables renamed v0,v1,..., module paths, operator spellings and binder keywords erased, sorts canonicalised (scheme dk-shape-v1). No dictionary is consulted. Some provers cannot state the same shape -- Isabelle elides binders, Why3 uses int where the others use nat -- so a second tier is emitted: cross_prover_skeleton_key (binders and sorts erased). Consumers join on tier 1 then tier 2; identity_scheme travels with every key and canonical_type keeps the rendered shape for debugging. E7 VectorModality moves from the 32-dim raw-text HashEmbedder to a 256-dim structural embedder: 1-3-grams of the canonical atom stream, L2-normalised, model echidna-corpus-structural-v2. corpus near canonicalises its query, so an SMT-LIB-shaped query retrieves Coq-shaped entries. HashEmbedder stays as compute_embeddings_legacy for GNN FEATURE_DIM parity and old octads. Also: echidna corpus identity exposes the grouping; GraphPayload and QueryResultEntry carry the structural key; capnp gains crossProverSkeletonKey/identityScheme and documents embedderDim; docs, ADR, CHANGELOG, STATE and the wiki source pages say what is actually true.

Canonical operators are emitted in **prefix** form, so infix input +//! (`x + y`) and SMT-LIB prefix input (`(+ x y)`) agree. +//! 4. **Associativity** — arrows and `↔` are right-associative; arithmetic +//! and comparison are left-associative. +//! 5. **Sorts** — `nat`/`ℕ` → `NAT`, `int`/`ℤ` → `INT`, `Prop`/`Set`/ +//! `Type` → `TYPE`, and so on.

De Bruijn's point — that binding structure, not the spelling of +//! variables, carries the meaning — is what is being exploited; the +//! indices here are assigned by first use rather than by binder depth +//! because real corpus statements routinely elide binders entirely, and +//! depth indices would then not line up (see Isabelle above). +//! 7. **Type ascriptions** — Isabelle's `(x::nat)` is a term ascription, +//! not a binder, and is unwrapped; Dedukti's explicit `eq Nat a b` +//! type argument is dropped so it matches the infix form. +//! 8. **Agda operator names** — `_<_`, `_+_`, `_≡_` are read as the +//! operator they wrap rather than as three punctuation tokens. +//! +//! ## What is *not* normalised +//! +//! Commutativity, associativity and other equational theories are **not** +//! applied: `x + y` and `y + x` are different shapes, deliberately. Nor is +//! the calculus changed: a statement that mentions `WellFounded` keeps +//! `WellFounded`. This is a syntactic identity key, not a decision +//! procedure, and the docs say so. +//! +//! The Rust here is a transcription of a Python prototype that was run +//! against the spellings above before it was ported; the unit tests at the +//! bottom of the file pin each of them. + +#![allow(dead_code)] + +use sha2::{Digest, Sha256}; + +/// Version tag for the normalisation scheme, stored next to every key so a +/// future change of rules cannot be mistaken for a change of theorem. +pub const SCHEME: &str = "dk-shape-v1"; + +/// How much of the statement a key is known to preserve. +#[derive(Debug, Clone, Copy, PartialEq, Eq, PartialOrd, Ord, serde::Serialize, serde::Deserialize)] +pub enum KeyTier { + /// Bindings and sorts survived: the strongest key. + Structural, + /// Binders/sorts were erased to get a match. + Skeleton, + /// The statement did not parse into a term; keyed on normalised text. + Text, +} + +impl KeyTier { + pub fn as_str(self) -> &'static str { + match self { + KeyTier::Structural => "structural", + KeyTier::Skeleton => "skeleton", + KeyTier::Text => "text", + } + } +} + +/// A declaration's structural identity. +#[derive(Debug, Clone, PartialEq, Eq, serde::Serialize, serde::Deserialize)] +pub struct StructuralKey { + /// Version of the normalisation rules that produced this key. + pub scheme: String, + /// Canonical prefix shape, binders and sorts included. + pub shape: String, + /// Canonical prefix shape with binders and sorts erased. + pub skeleton: String, + /// SHA-256 of `shape`, hex. + pub key: String, + /// SHA-256 of `skeleton`, hex. + pub skeleton_key: String, + /// Which tier this declaration's shape is trustworthy at. + pub tier: KeyTier, +} + +// =========================================================================== +// Vocabulary +// =========================================================================== + +/// Operator spellings → canonical operator.

All seven were in code added before the gates could run on this branch: * canonical.rs: 'loop { let op = match self.op_at() { .. None => break } }' is the while-let clippy wants. * creusot.rs: build ParsedFile with `..Default::default()` instead of reassigning `imports` afterwards; merge the two identical DeclKind::Data arms (type/static and const-not-fn) behind a named predicate; collapse the nested cfg(creusot) if. * spark_ada.rs: `loop { let Some(..) = .. else { break } }` is a while-let; drop the needless `&toks`; collapse the nested end-name if. No behaviour change: the merged arms both produced (DeclKind::Data, k + 1), and the loop rewrites break at the same points.

Jewell" Date: Thu, 22 Oct 2026 18:56:19 +0000 Subject: [PATCH 33/33] fix(corpus): stop the canonical parser collapsing a bracketed group to its operator Six tests in the corpus suite disagreed on exactly one input shape: an SMT-LIB (or any bracketed) statement. `(assert (forall ((x Nat) (y Nat)) (= (+ x y) (+ y x))))` canonicalised to `(PI [NAT NAT] EQ)` instead of `(PI [NAT NAT] (EQ (ADD v0 v1) (ADD v1 v0)))`. The cause is in Parser::app. atom() reads a bracketed group by recursing into expr(), so the group comes back as an already-applied Node::Op. app() then checked `if let Node::Op(op, _) = head` to decide whether it was looking at a *prefix* operator (`eq Nat a b`), and for a group it was not: it tried to gather further arguments, found none before the closing bracket, and fell into `args.is_empty()` -> Node::Name(op). The group's operands were dropped on the floor, which also flattened right-associative arrows: `(B -> C) -> (A -> B) -> A -> C` lost its parenthesised operands. Fix: remember whether the head came from a group, and if so return it as parsed. Prefix operators written as tokens are unaffected. This restores the add-commutativity identity across Coq, Lean 4, Idris 2, SMT-LIB and Dedukti (canonical.rs x4, embed.rs, octad.rs).
