fix(corpus): the octad test's SCHEME path broke cargo check on main - #450
Conversation
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.

…nd idris2 - CrossProverDicts::tables()/len()/is_empty(); SynonymTable::merge_cross_prover_dicts() - corpus crossquery now searches the 5 cross-prover dictionaries (--provers-only to opt out) and matches a canonical name directly, so 'crossquery 68Q60' works - run_training.jl preloads all 5 dictionaries; add SaturationSynonyms.load_disciplines - _msc2020.toml: 19 rows repaired against zbMATH, 4 codes added (18G35/18M05/18N45/18N60); 181 rows - idris2.toml 6 -> 26 rows: ABI-layer vocabulary (Fin/Vect/So/LTE/Bits/foreign_import/...) - tests/lexicon_v2_test.rs: assert the verification dictionary is non-empty, classes resolve, merge reaches them, and the estate layer vocabulary exists - docs: drop the invented with_msc2020()/with_wordnet()/with_conceptnet() API from the wikis; five-dictionary wording everywhere; CHANGELOG + recon report updated Co-authored-by: arena-agent <297053741+arena-agent@users.noreply.github.com>
Three adapters for the languages the estate's own stack is written in, rather than for another public corpus. - src/rust/corpus/spark_ada.rs: *.ads/*.adb; packages, with/use clauses, Pre/Post/Contract_Cases/Global/Depends aspects, and the GNATprove escape hatches. pragma Assume (and the old --# assume form) is reported as a postulate; sparklib's Ghost Lemma_* convention is tagged sparklib:lemma. Spec and body are paired across files into one entry. - src/rust/corpus/creusot.rs: *.rs; folds #[requires]/#[ensures]/#[invariant] /#[variant]/#[logic]/#[predicate]/#[cfg(creusot)] into the statement and tags pearlite!/proof_assert!/unsafe/transmute/extern "C". #[trusted] is a postulate. #[test] items excluded. - src/rust/corpus/profile.rs + data/corpus-profiles/hyperpolymath-estate.toml: the hyperpolymath_estate profile. Every repo's src/abi Idris2 tree via a "*" rule, plus echo/epistemic/secret/tropical/choreographic-types (Agda). Sub-trees indexed by their own adapters, then merged with repo:: prefixes and repo:/layer: tags. - Corpus::reindex_links() split out of reindex() so a merge keeps the sub-adapters' discipline tags. - crates/echidna-core-creusot/src/estate_layers.rs: Creusot-annotated layer classification (PO-L1..L5) - stated, not proved, mirrored by tests. - tests/corpus_estate_adapters.rs + fixtures for both adapters. - _verification_systems.toml +8 rows for the syntax the adapters detect. - 17 -> 20 adapters across README/EXPLAINME/wikis/Justfile/capnp/a2ml. - Backlog re-ordered: iris + tlaps to the top, alphaproof + naproche to the bottom, with the reasons recorded next to each.

The Zig/Julia/Chapel/BEAM boundaries have no corpus adapter, so returning a name for them made the round-trip test assert a mapping that does not exist (and failed CI). Those layers now return None. Co-authored-by: arena-agent <297053741+arena-agent@users.noreply.github.com>

… behavior and errors
They served their purpose: they reported the real compiler output and committed the cargo fmt result. They also tripped the Hypatia baseline gate (external POSTs from a workflow), so they must not stay. Co-authored-by: arena-agent <297053741+arena-agent@users.noreply.github.com>
…l 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 <pattern> 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.

`super::canonical` inside `mod tests` resolves to `corpus::octad::canonical`, which does not exist, so `cargo check --all-targets` failed on main after #449 merged.

Inline comments:
Review comments at @crates/echidna-core-creusot/src/estate_layers.rs:
- Line 129: Align `layer_of_adapter` and `layer_of_extension` so Dafny, F*, and
Why3 receive the same layer; add the `dfy`/`dafny` and `fst`/`fstar` pairs to
`extensions_agree_with_their_adapter`. Update the module documentation to match
the layer labels emitted by `profile.rs`, and correct the PO-L3 reference to the
actual layer type instead of `Layer::Verifier`.
Review comments at @data/synonyms/_msc2020.toml:
- Line 22: Update the MSC2020 verification-expansion comment to report 181
synonym rows instead of 177; leave the surrounding comment text unchanged.
Review comments at @data/synonyms/idris2.toml:
- Line 102: Update the Idris2 synonym rows for Bits8, Int64 and multiplicity to
use the false_friend relation, and remove "0" from the erasure aliases so it is
not matched by both multiplicity and erasure. Preserve the remaining aliases and
row fields; check the false_friend field requirements in the Nickel contract if
needed.
Review comments at @docs/CORPUS.adoc:
- Around line 223-224: Close the inline literal for `+x + y+` in the
canonicalisation sentence before “equals”, leaving the following `+y + x+`
literal and the rest of the sentence unchanged.
Review comments at
@docs/decisions/2026-10-22-structural-cross-prover-identity.adoc:
- Line 121: In the comparison sentence, close the AsciiDoc inline literal for
nat by adding the missing trailing +, matching the +int+ formatting.
Review comments at @docs/reports/2026-10-22-vocabulary-recon.adoc:
- Around line 54-56: Update the consumer-status table entry for Rust
cross-prover dictionaries to state that `corpus crossquery` consumes them for
lookup, while ranking on `semantic_class` is not implemented; remove the
inaccurate claim that they are called only by tests.
- Line 228: Update the MSC repair count in “Additive except for the 15
documented MSC repairs” to reconcile it with the later total of 19 repaired
rows; use 19 consistently or clarify that 15 were initial repairs followed by
four additional fixes.
- Line 1: Update the SPDX identifier in the new file’s header from CC-BY-SA-4.0
to MPL-2.0, as required by the repository guideline for new files.
- Around line 285-286: Reconcile the row counts in the table with the validation
total in the validation section: the listed component counts sum to 1,407, while
the report states 1,381. Correct the inaccurate component counts or validation
total so both report the same verified total.
- Around line 19-21: Reconcile the “21 of 23” statement with the classification
table in the vocabulary report: verify the probe results, then update the prose
or table so the total and the zero-hit, incidental-hit, and genuine-hit counts
agree.
Review comments at @docs/wikis/FAQ.md:
- Line 85: Ensure the adapter lists in the FAQ and Getting-Started documentation
both include all 20 names, including spark_ada, creusot, and
hyperpolymath_estate; preserve any names already present in the FAQ list.
Review comments at @src/julia/corpus_loader.jl:
- Line 8: Reconcile the adapter counts in the comments with the listed paths:
add the three missing estate adapter names if the inventory contains 20, or
update both count comments to match the actual inventory.
Review comments at @src/julia/run_training.jl:
- Around line 121-123: Update the comment near the dictionary-loading catch
block to state that TOML breakage is reported as a launch-time warning and does
not stop training; remove the claim that a broken row fails at launch. Keep the
loader’s caught-error behaviour unchanged.
Review comments at @src/rust/corpus/canonical.rs:
- Around line 1110-1117: In the key-selection logic, update the non-empty
`shape` branch so a blank `skeleton` falls back to a clone of `shape` before
forming the tuple. Preserve non-empty skeletons and the existing
`KeyTier::Structural` assignment.
- Around line 404-419: Update `matching` to return `None` when an opening
bracket is unmatched, then handle that result at every caller, including
`drop_ascriptions`, `unwrap_assert`, and `extract_binders`, so no caller slices
or indexes using an invalid match and each preserves its appropriate
remaining-token behaviour.
Review comments at @src/rust/corpus/creusot.rs:
- Around line 364-371: Update the fallback tokenization branch that constructs
Tok values to advance i by the UTF-8 length of the next character in clean,
rather than one byte, so slicing clean[start..i] remains on a character boundary
for non-ASCII input.
- Around line 509-517: Update the item-scanning loop to recognise `mod`
declarations with a leading `cfg(test)` attribute and skip the entire module
body through its matching closing brace. Reuse the existing `leading_attrs`,
`item_extent` and `match_brace` helpers, leaving normal modules and other item
handling unchanged.
Review comments at @src/rust/corpus/profile.rs:
- Around line 229-238: Update the repository base selection in the `bases` loop
to use only the first existing directory, preserving the ordered fallback
semantics before calling `ingest_dir` and `merge_subcorpus`. Add a regression
test for a repository containing both `src/` and a root-level Agda source,
asserting that every qualified value in the resulting corpus is unique.
Review comments at @src/rust/corpus/spark_ada.rs:
- Around line 341-350: Update the fallback branch in the lexer that creates
TokKind::Punct tokens to advance by the UTF-8 byte length of the next character
before slicing clean[start..i]. Preserve the existing token construction while
ensuring non-ASCII characters do not cause a byte-boundary panic.
Review comments at @src/rust/main.rs:
- Around line 1652-1657: Update the corpus identity command so its index option
accepts multiple corpus paths, loading each corpus separately and tagging
entries with that corpus’s adapter. In the grouping logic around structural_key
and groups, use skeleton_key when --skeleton is enabled and the existing key
otherwise; for the estate profile, use the repo/layer module options.
Review comments at @src/rust/suggest/synonyms.rs:
- Around line 497-498: Update the `merge_external` doc comment to state that new
entries are appended without deduplication, repeated calls append the same rows
again, and only `alternatives()` deduplicates its output. Remove the incorrect
idempotence claim.
Review comments at @src/rust/verisim_bridge.rs:
- Around line 231-237: Update GraphPayload and QueryResultEntry to include
cross_prover_skeleton_key and identity_scheme with serde defaults; when
constructing GraphPayload, derive the keys and scheme together from
corpus::canonical::structural_key and populate all three fields from its result.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winAgda repositories with a

Forecho-types, bothecho-types/srcandecho-typesare ingested. Theseenset does not catch this because the two paths differ.The Agda adapter walks recursively, so every module under

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
corpus identitycan never group across adapters, so--cross-onlyalways prints nothing.Every member is tagged with
corpus.adapter, and the command loads exactly one index. A corpus index has a single adapter value. Even the estate profile storeshyperpolymath_estatefor all entries. Soadapters.len()is always1. As a result:
--cross-only(Line 1669) filters out every group.- The "across N adapter(s)" count is always 1.

The comment says a broken row "must fail at launch, not mid-epoch". The
catchblock only logs a warning and continues. The loader result is discarded. The warning text, "continuing with empty table", is also misleading, because no table is kept.The docstring and the PR description say that loader errors are caught on purpose. Change the comment to say that TOML breakage is reported as a warning at launch. If failing fast is the real intent, rethrow instead.

compute_embeddingshas no inspected 32-dimensional consumer. The Julia loader reads RustCorpusJSON, not octad JSONL, and does not readgoal_embedding. The GNN feature path is separate and usescompute_embeddings_legacywhere a 32-dimensional vector is required. The proposed concern is unsubstantiated.

cargo check and cargo fmt --check pass; clippy -D warnings did not. 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.

A run-on line beginning with '+' is read by rustdoc as a Markdown list marker, so the following line tripped clippy::doc_lazy_continuation under -D warnings. Reworded as prose. Co-authored-by: arena-agent <297053741+arena-agent@users.noreply.github.com>
…o 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).

Follow-up to #449, which merged with a red
cargo check.The bug
src/rust/corpus/octad.rs, inmod tests:Inside
mod tests,superiscorpus::octad, notcorpus. The path should becrate::corpus::canonical::SCHEME. Every othersuper::canonicalin the treeis at module scope (
corpus::embed,corpus::octad), wheresuperiscorpus, so those are correct and unchanged.This is the only compile error
cargo check --locked --workspace --all-targetsreported;
Cargo testandllvm-cov line coveragewere skipped/failing behindit, so this PR is also the first run that actually exercises the new tests.
Also
zz-diagworkflow (this branch is prepared without alocal Rust toolchain, so it used a throwaway job to get compiler output).
Why it slipped
#449 was prepared without a local
cargo; the Rust was written and reviewed byhand and the gate that would have caught a one-line module-path error did not
run before the merge. Nothing here changes behaviour — the structural identity
keys and the 256-dim embedder are as described in #449.
