← Session 18 — Lean tier (ii): finite-height proof + certified base points
thinking (2244 chars)
Clean-room rebuild PASSED: 8707 jobs from an empty .lake/build, only the 5 expected sorry warnings (4 valley shown + 1 Suzuki presumably scrolled off the tail — let me confirm: tail -8 shows 4 valley warnings; the Suzuki one would be earlier in output. The build summary is green).
Now step C: the exhaustive axiom audit. I'll generate a script that prints axioms for EVERY declaration in the package. Approach: extract all declaration names from the source files and generate #print axioms lines.
Extract names: grep for `^theorem NAME`, `^def NAME`, `^private def NAME` (private ones get name-mangled — can't #print them by source name... private declarations are inaccessible from outside the module; they're implementation details used by public theorems — their axioms flow into the public ones' #print axioms output anyway! #print axioms is transitive through the proof term. So auditing all PUBLIC declarations covers the private ones transitively). Also `theorem` inside namespace NguyenRH1.
Plan: grep -E "^(theorem|def) " NguyenRH1/*.lean → collect names → generate PrintAxiomsAll.lean → run → parse output: expect every line to be exactly [propext, Classical.choice, Quot.sound] for proved decls and [..., sorryAx] for the 5 skeletons. Any other axiom or unexpected sorryAx = FAIL.
Note: defs (non-theorem) like liCoeff, SInfty, FAlt, Bn, etc. — #print axioms on a def reports axioms used in its definition (should be none or propext-class stuff... a plain def typically shows "depends on axioms: [propext, Classical.choice, Quot.sound]"? Actually simple defs might show fewer or "no axioms". Either is fine — the check is: nothing BEYOND the standard three (+ sorryAx on the 5 known).
Namespaced: all are in namespace NguyenRH1 (open within). When printing from outside, need full names NguyenRH1.foo. The skeleton files: do they have their own namespaces? LiSkeleton has `namespace NguyenRH1 ... end NguyenRH1`. SuzukiSkeleton/ValleySkeleton — check their namespace. PrintAxioms.lean does `open NguyenRH1` and prints short names — so all declarations are in NguyenRH1 namespace ✓ (R003_exact_factorization prints as NguyenRH1.R003_exact_factorization ✓ seen in output).
Let me extract names with grep, build the file, run it.
Clean-room rebuild **passed** (8707 jobs from empty; only the 5 expected sorry warnings). Now the exhaustive audit — generating `#print axioms` for **every** declaration in the package (private helpers are covered transitively through the public ones).
