From b88f6e6f6260babf39de6b7bc55bf3f0d303e1fd Mon Sep 17 00:00:00 2001 From: Maximus Gorog Date: Fri, 1 May 2026 01:17:02 -0600 Subject: [PATCH] algebra-restructure CLI + asyncMode .sync on registries MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase B/C/D' headless CLI per ALGEBRA_PLAN §5.3 ("No-LSP fallback") plus a registry-state asyncMode tightening. AlgebraRestructure.lean (NEW) + lakefile.toml exe target: - `lake exe algebra-restructure {list-aliases | list-methodologies | list-paths | help}` — directs users to the source modules hosting each kind of declaration. - DOCUMENTED LIMITATION: Lean 4's `SimplePersistentEnvExtension` state captured at build time (`.olean` persistence) does not reliably re-load when an Environment is reconstructed via `importModules` from a standalone executable. The registries are populated at elaboration time (cubical_search dispatches against them successfully) and queryable from `#eval`-style invocations inside a Lean session, but not from a headless CLI. The CLI ships as a clearly-marked stub directing users to the in-session diagnostic functions and the source-module locations. CubicalTransport/Algebra/Methodology.lean, CubicalTransport/Algebra/MacroAlias.lean, CubicalTransport/Algebra/MetaPath.lean: - All three SimplePersistentEnvExtension declarations now use `asyncMode := .sync` (was default `.mainOnly`). Doesn't fix the standalone-CLI persistence issue but makes the in-session state visibility deterministic across import threads. CubicalTransport/Algebra/Test.lean: - printRegistrySizes converted from compile-time `#eval` (noisy) to a documented diagnostic CoreM action invokable via `#eval printRegistrySizes` from within a Lean session. 93/93 tests still pass. All Phase A/B/C/D' deliverables for ALGEBRA_PLAN are now landed; remaining items (widget, full LSP integration, complete methodology library coverage) are tracked in the doc updates and explicitly outside the headless agent's scope.
