giles	b80871ac4f	kernel: $let* sequential let + multi-body $let + 8 tests [nothing] ... $let* nests env-extensions one per binding — each binding sees earlier ones. $let now also accepts multi-expression bodies. 260 tests total.	2026-05-11 21:11:01 +00:00
giles	9ff5d1b464	kernel: $and? / $or? short-circuit + 10 tests [shapes-reflective] ... Operatives (not applicatives) so untaken args are not evaluated. Empty $and? = true, empty $or? = false (Kernel identity convention). Returns last evaluated value, not bool-coerced. Sketched reflective short- circuit API: identical protocol across reflective Lisps because operative semantics are forced — an applicative variant defeats the purpose. 252 tests total.	2026-05-11 21:09:20 +00:00
giles	5fa6c6ecc1	kernel: $cond/$when/$unless + 12 tests [nothing] ... Standard Kernel control flow. $cond walks clauses in order with `else` catch-all; clauses past the first match are NOT evaluated. $when/$unless are simple guards. 12 tests, 242 total.	2026-05-11 21:08:08 +00:00
giles	a4a7753314	kernel: $quasiquote runtime + reflective/quoting.sx sketch [shapes-reflective] ... kernel-quasiquote-operative walks the template via mutually-recursive knl-quasi-walk ↔ knl-quasi-walk-list. $unquote forms eval in dyn-env; $unquote-splicing splices list-valued results. No depth tracking (nested quasiquotes flatten). 8 new tests, 230 total. Sketched the universal reflective quoting kit API for the eventual Phase 7 extraction.	2026-05-11 21:06:35 +00:00
giles	af8d10a717	kernel: multi-expression body for $vau/$lambda + 5 tests [nothing] ... :body slot holds a LIST of forms now (was single expression). New knl-eval-body in eval.sx evaluates each form in sequence, returning the last. $vau and $lambda accept (formals env-param body...) / (formals body...). No $sequence dependency. 223 tests total.	2026-05-11 21:04:19 +00:00
giles	c21eb9d5ad	kernel: reader macros + 8 tests (Phase 1 closure) [consumes-lex] ... Parser now reads 'expr, \`expr, ,expr, ,@expr as the four standard shorthands. Quote uses existing $quote operative; quasiquote / unquote / unquote-splicing recognised but not yet expanded at runtime (left for first consumer to drive). 218 tests total across six suites.	2026-05-11 21:01:01 +00:00
giles	d896685555	kernel: Phase 7 reflective API proposal — partial [proposes-reflective-extraction] ... Two-consumer rule blocks actual extraction. API surface fully documented across four candidate files: env.sx (Phase 2), combiner.sx (Phase 3), evaluator.sx (Phase 4), hygiene.sx (Phase 6). ~25 functions, ~500 LoC estimate when second consumer materialises. Candidates listed in priority order: metacircular Scheme, CL macro evaluator, Maru. Loop complete: 210 tests, 7 commits, one feature per commit.	2026-05-11 20:58:41 +00:00
giles	bf7ec55e92	kernel: Phase 6 hygiene — $let + $define-in! + 18 tests [shapes-reflective] ... Hygiene-by-default was already present: user operatives close over static-env and bind formals + body $define!s in (extend STATIC-ENV), caller's env untouched. $let evaluates values in caller env, binds in fresh child env, runs body there. $define-in! explicitly targets an env. Full scope-set / frame-stamp hygiene is research-grade and documented as deferred future work in the reflective API notes.	2026-05-11 20:57:47 +00:00
giles	45789520ce	kernel: Phase 5 encapsulations + promise demo + 19 tests [nothing] ... make-encapsulation-type returns (encapsulator predicate decapsulator). Fresh empty dict per call as family identity — SX dict reference equality gives unique per-family opacity. Encap/decap/pred close over the family marker; foreign values fail both predicate and decap. Classic promise demo: (force (delay (lambda () (+ 19 23)))) → 42.	2026-05-11 20:54:31 +00:00
giles	b91d8cf72e	kernel: Phase 4 standard env + factorial + 49 tests [shapes-reflective] ... kernel-standard-env extends kernel-base-env with $if/$define!/$sequence/ $quote, reflection (eval/make-environment/get-current-environment), binary arithmetic, comparison, list/pair, boolean primitives. Headline test is recursive factorial (5! = 120, 10! = 3628800). Recursive sum, length, map-add1, closures, curried arithmetic, and a $vau-using-$define! demo also covered.	2026-05-11 20:50:34 +00:00
giles	0da39de68a	kernel: Phase 3 $vau/$lambda/wrap/unwrap + 34 tests [shapes-reflective] ... User-defined operatives via $vau; applicatives via $lambda (wrap ∘ $vau). wrap/unwrap as Kernel-level applicatives. kernel-call-operative forks on :impl (primitive) vs :body (user) tag. kernel-base-env wires the four combiners + operative?/applicative? predicates. Env-param sentinel `_` / `#ignore` → :knl-ignore (skip dyn-env bind). Flat parameter list only; destructuring later. Headline test: custom applicative + custom operative composed from user code.	2026-05-11 07:43:45 +00:00
giles	7e57e0b215	kernel: Phase 2 evaluator — lookup-and-combine + 36 tests [shapes-reflective] ... kernel-eval/kernel-combine dispatch on tagged values: operatives see un-evaluated args + dynamic env; applicatives evaluate args then recurse. No hardcoded special forms — $if/$quote tested as ordinary operatives built on the fly. Pure-SX env representation {:knl-tag :env :bindings DICT :parent P}, surfaced as a candidate lib/guest/reflective/env.sx API since SX make-env is HTTP-mode only.	2026-05-10 20:50:42 +00:00
giles	cbba642d7f	kernel: Phase 1 parser — s-expr reader + 54 tests [consumes-lex] ... R-1RK lexical syntax: numbers, strings, symbols, #t/#f, (), nested lists, ; comments. Strings wrap as {:knl-string ...} to distinguish from symbols (bare SX strings). Reader macros deferred to Phase 6 per plan. Consumes lib/guest/lex.sx character predicates.	2026-05-10 20:42:53 +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).
