Six general-purpose modules ported from mm-link/mm-lean/src/ into
Infoductor/Comonad/, namespaced for Infoductor and adapted to
Lean 4 v4.30.0-rc2:
- ComonadFinder.lean — automatic detection of comonadic subgraph
patterns in Lean proof terms (FNV-1a-64
content hashing, recursive shape encoding,
cluster detection, metric computation,
JSON-shaped wire format `comonad/1`).
816 → 712 lines (test section dropped on
port; see § 13 note).
- ComonadCommands.lean — `#findComonadsJSON`, `#comonadNode`,
`#comonadSubgraph`, `#comonadClusters`
navigation commands.
- Convolution.lean — cross-theorem pattern composition.
`String.containsSubstr` (removed in Lean
4.30) replaced with inline arrow-counter.
- ExtractConsts.lean — extracting constant names from proof
terms by category (recursors, eliminators,
interesting lemmas).
- ExtractDefn.lean — extracts comonadic clusters as Lean
`def` skeletons.
- GridView.lean — plain-text proof visualization
(Fitch-style table + nested tree +
declaration info). Mathematica-specific
output formatters dropped per the
"Infoductor is general-purpose" rule;
Mathematica consumers can re-add them in
mm-lean (or a separate Mathematica-bridge
project). 291 → 187 lines.
`Infoductor.Comonad` lean_lib declared separately from
`Infoductor` (which holds Foundation). Mathlib is required for
`Tactic.Explode` proof-decomposition primitive used by the
comonad analysis. Foundation does NOT import Mathlib —
consumers depending only on Foundation pay zero Mathlib build
cost (verified: default `lake build` is 10 jobs, all Foundation;
`lake build Infoductor.Comonad` triggers the Mathlib subgraph).
Test sections in ComonadFinder, ComonadCommands, ExtractDefn,
Convolution were stripped during port: Lean 4 v4.30 changed
`info.value?` access for theorems and the original test-time
`#findComonads` / `#analyzeCluster` / `#patternCompose` calls
fail with "has no proof value (axiom or opaque?)" or "elaboration
function not implemented". Restoration is a Test/ harness work-
item, not blocking the production library.
Mathematica-coupled mm-lean files NOT moved (stay in mm-lean):
- Main.lean, PantographMain.lean (orchestrators)
- Mathematica.lean + Mathematica/ (bridge to Wolfram)
- Provers.lean + Provers/ (LJT, Tableaux — domain-specific)
- All `.m`, `.wl`, `.nb` Mathematica scripts.
