Loop closer documenting what 10 feature commits landed across the
session. Phase-by-phase outcomes captured, including the SX cond
multi-expression bug found and fixed during Phase 4.
Chisel ledger:
- env.sx already EXTRACTED with Scheme as third consumer
- evaluator.sx + quoting.sx second-consumer-ready for follow-on
kit-extraction commits
- hygiene.sx still awaits the deferred Phase 6c (scope-set work)
- combiner.sx and short-circuit.sx don't apply (Scheme has no
fexprs and uses syntactic and/or)
Deferred phases listed: full hygiene, nested quasi-depth, R7RS
module rich features, dotted-pair syntax, full call/cc-wind
interaction.
Loop's defining feature: lib/guest CHISELLING discipline — every
commit had a chisel note, and the cumulative work satisfies the
two-consumer rule for three new kit extractions.
11-phase plan from parser through R7RS conformance. Explicitly maps
which reflective kits Scheme consumes:
- env.sx (Phase 2) — third consumer, no cfg needed
- evaluator.sx (Phase 7) — second consumer, unblocks extraction
- hygiene.sx (Phase 6) — second consumer, drives the deferred
scope-set / lifted-symbol work
- quoting.sx (Phase 10) — second consumer, unblocks extraction
- combiner.sx — N/A (Scheme has no fexprs)
Correction to earlier session claim: a Scheme port unlocks THREE
more reflective kits, not four. combiner.sx stays Kernel-only.
