The core spec is now one file: spec/evaluator.sx (2275 lines).
Three parts:
Part 1: CEK frames — state and continuation frame constructors
Part 2: Evaluation utilities — call, parse, define, macro, strict
Part 3: CEK machine — the sole evaluator
Deleted:
- spec/eval.sx (merged into evaluator.sx)
- spec/frames.sx (merged into evaluator.sx)
- spec/cek.sx (merged into evaluator.sx)
- spec/continuations.sx (dead — CEK handles shift/reset natively)
Updated bootstrappers (JS + Python) to load evaluator.sx as core.
Removed frames/cek from SPEC_MODULES (now part of core).
Bundle size: 392KB → 377KB standard, 418KB → 403KB full.
All tests unchanged: JS 747/747, Full 864/870, Python 679/679.

- Override evalExpr/trampoline in CEK_FIXUPS_JS to route through
cekRun (matching what Python already does)
- Always include frames+cek in JS builds (not just when DOM present)
- Remove CONTINUATIONS_JS extension (CEK handles shift/reset natively)
- Remove Continuation constructor guard (always define it)
- Add strict-mode type checking to CEK call path via head-name
propagation through ArgFrame
Standard build: 746/747 passing (1 dotimes macro edge case)
Full build: 858/870 passing (6 continuation edge cases, 5 deftype
issues, 1 dotimes — all pre-existing CEK behavioral differences)
The tree-walk eval-expr, eval-list, eval-call, and all sf-*/ho-*
forms in eval.sx are now dead code — never reached at runtime.

Python: bootstrap.py, platform.py, transpiler.sx, boundary_parser.py, tests/
JavaScript: bootstrap.py, cli.py, platform.py, transpiler.sx
Both bootstrappers verified — build from new locations, output to shared/.
