giles	858d35a68c	maude: Phase 5 system modules + rewrite rules (21 tests, 159 total) ... lib/maude/rewrite.sx: rl/crl transitions interleaved with eq normalisation. mau/rewrite = default strategy (top-down, leftmost-outermost, first rule); mau/rew bounded; mau/search = BFS reachability over all successors. lib/maude/fire.sx: short-circuiting matcher (mau/fire-eq) — finds the first productive match instead of enumerating the whole solution set. Fixes the exponential blowup of AC rewriting on many identical elements (8 coins: 60s+ to <1s). Eager match-multiset kept only for match-all / search. Verified on AC coin-change, traffic light, branching search, crl clock. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-07 15:23:06 +00:00
giles	1747bbd944	maude: Phase 4 conditional equations (19 tests, 138 total) ... lib/maude/conditional.sx — condition-aware reducer. ceq fires only when its guard holds: equational guards (l=r reduce to same normal form) and boolean guards (term reduces to true), evaluated by recursing through the same reducer. Verified on gcd, insertion sort, max, even. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-07 15:06:00 +00:00
giles	2378056cb3	maude: Phase 3 — equational matching modulo assoc/comm/id (28 tests, 119 total) ... The chisel. lib/maude/matching.sx: multi-valued matcher mau/mm returning ALL substitutions, dispatching on op theory (free/comm/assoc/AC). Identity lets variables grab empty blocks. AC-canonical form (mau/canon) powers ac-equal? and deterministic printout. AC rewriting extends f-AC equations with rest vars so a rule fires on any sub-multiset/subword; mau/first-change only commits rewrites that change the canonical form (idempotency/identity terminate). Verified on multiset rewriting, set theory, group equations. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-07 15:01:07 +00:00
giles	10906d4ffc	maude: Phase 2 syntactic equational reduction (26 tests, 91 total) ... lib/maude/reduce.sx — one-sided syntactic matching (non-linear patterns via bound-var equality), immutable substitutions, innermost fixpoint normalisation. Tested on Peano arithmetic, list ops, a propositional logic simplifier, and non-linear matching. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-07 14:46:02 +00:00
giles	9f87206949	maude: Phase 1 parser — fmod/mod modules, signatures, mixfix terms (65 tests) ... Term representation (lib/maude/term.sx) plus a module parser (lib/maude/parser.sx) consuming lib/guest/lex + pratt: - whitespace+bracket tokenizer (--- / *** comments) - mixfix classification (split op names on _): infix/prefix/postfix/const - precedence-climbing term parser over a pratt table built from op decls - fmod/mod ... endfm/endm with sort/subsort/op/var/eq/ceq/rl/crl - transitive subsort hierarchy + operator overloading queries Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-07 14:43:02 +00:00
giles	9dd9fb9c37	plans: layered-stack framing + chisel sequence + loop scaffolding ... Design + ops scaffolding for the next phase of work, none of it touching substrate or guest code. lib-guest.md: rewrites Architectural framing as a 5-layer stack (substrate → lib/guest → languages → shared/ → applications), recursive dependency-direction rule, scaled two-consumer rule. Adds Phase B (long-running stratification) with sub-layer matrix (core/typed/relational/effects/layout/lazy/oo), language profiles, and the long-running-discipline section. Preserves existing Phase A progress log and rules. ocaml-on-sx.md: scope reduced to substrate validation + HM + reference oracle. Phases 1-5 + minimal stdlib slice + vendored testsuite slice. Dream carved out into dream-on-sx.md; Phase 8 (ReasonML) deferred. Records lib-guest sequencing dependency. datalog-on-sx.md: adds Phase 4 built-in predicates + body arithmetic, Phase 6 magic sets, safety analysis in Phase 3, Non-goals section. New chisel plans (forward-looking, not yet launchable): kernel-on-sx.md — first-class everything, env-as-value endgame idris-on-sx.md — dependent types, evidence chisel probabilistic-on-sx.md — weighted nondeterminism + traces maude-on-sx.md — rewriting as primitive linear-on-sx.md — resource model, artdag-relevant Loop briefings (4 active, 1 cold): minikanren-loop.md, ocaml-loop.md, datalog-loop.md, elm-loop.md, koka-loop.md Restore scripts mirror the loop pattern: restore-{minikanren,ocaml,datalog,jit-perf,lib-guest}.sh Each captures worktree state, plan progress, MCP health, tmux status. Includes the .mcp.json absolute-path patch instruction (fresh worktrees have no _build/, so the relative mcp_tree path fails on first launch).
