Diagrams:
- asm-architecture.dot: adds GC_NAIVE memory cluster (bump, free
list, conservative stack scan) + meta-GC (with-arena) cluster
showing the reset path; updates line count (4968 -> 6645),
builtin count (91 -> 95+), mentions native hash-table-* /
hash-set-* and the GC-build primitives (with-arena, gc-collect,
gc-stats, arena-stats).
- benchmark-binary-size.dot: adds second asm bar for the GC_NAIVE
build (27 KB stripped vs 23 KB bump-only); updated asm bump
size from 22 KB (stale) to actual 23 KB.
- benchmark-gc.dot (new): side-by-side peak RSS for asm bump-only
(134 MB), naive GC (1.1 MB), meta-GC arena (1.2 MB, 2000/2000
resets); embedded in §6.6.
- meta-gc-policy.dot (new): three-way decision tree at
(with-arena) exit — implicit-GC-fired / mark-in-arena-range /
no-mark-in-range -> skip / sweep / bulk-reset; embedded in
§6.6.1.
Stats:
- 975 verified assertions -> 980 (asm gained 5 via hash-table &
hash-set tests; 571 Python + 137 asm + 83 C + 189 shared).
- asm test count 132 -> 137 in the summary list, intro abstract,
and §11 tier table. Notes that the optional GC build passes
the same 137 independently (1,117 assertions total when both
asm binaries are exercised).
- Stale 4,968 LOC -> 6,645 already fixed in the prior commit;
the new asm-architecture diagram now matches.
PDF rebuilt, 2.58 MB (was 2.40 MB). All test suites green.
