From 218b2af6ab513ab2fd50a255b4b628255bb65d48 Mon Sep 17 00:00:00 2001 From: hyperpolymath <6759885+hyperpolymath@users.noreply.github.com> Date: Mon, 1 Jun 2026 18:54:31 +0100 Subject: [PATCH 01/13] docs(handover): declare prover/corpus saturation lane Parallel work alongside wave3/161-162 (chapel bench/telemetry). Hard exclusion list pins what this lane will NOT touch; lane scope declares the new corpus adapters, synonyms, exchange bridges, arbiter trio, and E-R schema formalisation work.

Timeouts contribute LR=1.0. 5 tests. - dempster_shafer.rs: belief-mass combination via Dempster's rule with explicit Empty conflict set. ArbiterError::HighConflict trip at k>0.95. Helper proven_mass(t,timeout) ramps mass from 0.95→0.50 as runtime approaches timeout. 6 tests. - pareto_arbiter.rs: multi-objective Pareto frontier over (confidence↑, latency↓, axiom_cost↓, certificate_size↓) with Tiebreak {MinAxiom, MinLatency, MaxConfidence, MinCertificate}. 6 tests. mod.rs registers the three new modules (additive only).

False positives inside string literals are acceptable; flag in `axiom_usage.other` for human review. +5. **Register in `src/rust/corpus/mod.rs`.** Add `pub mod your_adapter;` to the module list. +6. **Add the per-prover synonyms TOML** at `data/synonyms/.toml` with schema `[[synonym]]` rows (`canonical`, `aliases`, optional `tactic_class`, `semantic_class`).

mathlib4 / stdlib / +AFP / mizar-mml content. The detector returns whatever markers fire, +so a `partial`-marked cell can still produce real tags when the +specific declaration uses the relevant idiom; the matrix only +documents expected hit frequency for triage. + +## 5. Crosswalk to TypeLL / Katagoria / VCL-UT / Panll + +### 5.1 TypeLL + +Each `TypeDiscipline` variant has a Sigma parameter name returned by +`src/rust/disciplines/disciplines.rs::typell_sigma()`. The Sigma names are +single-token strings (`"HM"`, `"SF"`, `"Lin"`, `"Aff"`, `"Dep"`, +`"QTT"`, `"Echo"`, `"Cub"`, `"Trop"`, `"Cer"`, …) and exactly match +the discipline tag passed to `typell --discipline=` by +`src/rust/provers/hp_ecosystem.rs:63-126`. The Sigma table is the +single source of truth for the discipline ↔ CLI mapping; this +document does not re-list it. + +### 5.2 Katagoria + +Katagoria (`hyperpolymath/katagoria`, dispatched as +`ProverKind::KatagoriaVerifier` at +`src/rust/provers/hp_ecosystem.rs:66`) reserves invariant slots +keyed by discipline tag. The intended mapping — which tags populate +which Katagoria invariant slots — is **TBD — needs Katagoria spec +audit**. Until then, the detector emits the tag and Katagoria +consumers ignore unknown tags. + +### 5.3 VCL-UT + +VCL-UT (`src/rust/vcl_ut.rs:1-1083`) already exposes a 10-level +`TypeLevel` safety annotation. Discipline tags are orthogonal: a +VCL-UT query can additionally constrain by discipline, e.g. + +```text +select octad +where_discipline(TypeDiscipline::Linear) +where type_level >= TypeLevel::L7 +``` + +The VCL-UT planner pushes the discipline filter down to the +`octads_semantic` materialised view (E2 in `VERISIM-ER-SCHEMA.md`), +which indexes on the new `type_discipline_tags` array column. + +### 5.4 Panll + +Panll's type system is the union of all 39 disciplines plus +cross-discipline composition operators (per the +`panll/docs/type-system/` design notes). Discipline tags are +**pre-Panll annotation**: they are computed by adapters that pre-date +the Panll compiler, stored in VeriSimDB, and consumed downstream once +Panll lands. The contract is: + +- adapters MUST emit tags they detect, even if Panll cannot yet + consume them; +- Panll's compiler, when it ships, MUST read `type_discipline_tags` + as hints (not authoritative) and may refine or extend the set. + +## 6. Wire schema impact + +The `SemanticPayload` struct in `src/rust/verisim_bridge.rs` gains a +new field: + +```rust +pub struct SemanticPayload { + // ...existing fields... + pub type_discipline_tags: Vec, // kebab-case slugs +} +``` + +The slugs are the canonical discipline names from §2 (e.g. +`"hindley-milner"`, `"linear"`, `"echo"`, `"tropical"`). + +The Cap'n Proto schema at +`crates/echidna-wire/schemas/verisim_er.capnp` adds field 11 on the +`Semantic` struct: + +```capnp +struct Semantic { + # ...fields @0..@10 unchanged... + typeDisciplineTags @11 :List(Text); +} +``` + +VeriSimDB stores this as an `Array(LowCardinality(String))` column on +the `octads_semantic` table, with a secondary skip index for +discipline-filtered queries. The drift-detection SHA in §"Drift +detection" of `VERISIM-ER-SCHEMA.md` MUST be re-computed when this +field lands. + +## 7. Detection confidence + +The detector is heuristic; tags are emitted when cumulative marker +score for a discipline exceeds 0.7. Marker entries in +`MarkerRegistry` have shape: + +```rust +pub struct Marker { + pub pattern: String, // literal string or regex (compiled lazily) + pub discipline: TypeDiscipline, + pub weight: f64, // 0.0..1.0 + pub adapters: &'static [&'static str], // empty == language-agnostic +} +``` + +- **HIGH-confidence markers** like `@[ceremony]` are unambiguous — + weight 0.95. A single occurrence crosses the 0.7 threshold. +- **MEDIUM-confidence markers** like `forall` need corroborating + evidence (e.g. a type variable in scope) before they tag + System F or Rank-N. Typical weight 0.45–0.6. +- **LOW-confidence markers** like `!` (which could be linear-logic + exponential, boolean negation, factorial, or Haskell strictness) + carry weight 0.2 and require multiple co-occurring markers to fire. + +The `adapters` slice scopes a marker: `adapters: &[]` (empty) means +the marker is language-agnostic; `adapters: &["lean"]` restricts it +to Lean sources only. This matters because `!` means "linear bang" in +Linear Logic encodings but "decide" in Lean tactic scripts. + +## 8. Per-discipline owner-direction status + +Status of the nine disciplines the owner explicitly called out during +campaign scoping: + +- **linear**: ✓ detector + markers + synonyms shipped + (`data/synonyms/_disciplines.toml::[linear]`). +- **affine**: ✓ ditto. Cross-references the Rust borrow-checker + vocabulary (`move`, `Copy`, `Drop`) used in `idaptik` corpus. +- **dependent**: ✓ ditto. Routes through `DependentTypeChecker` + (`src/rust/provers/hp_ecosystem.rs:75`). +- **equality**: ✓ as part of subtyping/dependent; markers `=`, `≡`, + `==`, propositional-equality (`Path`, `Id`, `eq`). Not a standalone + Sigma; surfaces under `Dep` or `Hom` depending on context. +- **ceremonial**: ✓ markers shipped (`@[ceremony]`, `ritual`, + ceremonial-obligation slugs). Detector may need expansion as Panll's + ceremonial sub-language stabilises. +- **dyadic**: ✓ from echo-types (`hyperpolymath/echo-types`); routes + through `DyadicTypeChecker` + (`src/rust/provers/hp_ecosystem.rs:111`). +- **tropical**: ✓ from tropical-resource-typing repo; routes through + `TropicalTypeChecker` (`src/rust/provers/hp_ecosystem.rs:67`). +- **choreographic**: ✓ markers shipped (global-protocol syntax, + multi-role declarations); routes through + `ChoreographicTypeChecker` (`src/rust/provers/hp_ecosystem.rs:68`). +- **epistemic**: ✓ markers shipped (`K`, `K_i`, `knows`); routes + through `EpistemicTypeChecker` + (`src/rust/provers/hp_ecosystem.rs:69`). + +## 9.

Disciplines + that imply harder goals (Dep, QTT, Cub) shift the value prior down; + the model learns the offsets. +- **Policy head**: discipline tags constrain candidate tactics. For a + `Linear`-tagged goal, the policy head prefers tactics that respect + linearity (no duplication, no discarding). The constraint is a soft + prior implemented as a logit bias in the tactic-ranking softmax — + see the GNN service in `src/julia/server/gnn_api.jl`. + +## 10. Open follow-ups + +- **T1** — wire `type_discipline_tags` into `CorpusEntry` serde so + every adapter's emit path populates the field. +- **T2** — each per-language detector gets adapter-aware refinement + beyond plain text-matching (e.g. AST-walking the Coq term for + `Π`-binders rather than regexing the source). +- **T3** — Cap'n Proto schema delta on `Semantic @11`. +- **T4** — `src/julia/training/corpus_loader.jl` pass-through of the + 39-dim feature. +- **T5** — cross-reference echo-types repo + (`hyperpolymath/echo-types`) for the canonical Echo / Dyadic marker + set; audit pending.

Subsequent requests will surface any underlying transport problem explicitly. - verisim_bridge.rs: document the two `.unwrap_or(0)` zero-pad bytes in the base64 encoder as RFC 4648 §4-compliant; the `chunk.len()` guards below already mask them out of significant output. Verification: `cargo check --lib` clean; `cargo test --lib` = 1174 passed, 0 failed, 3 ignored (unchanged from pre-fix).
