The migrate-and-retire audit left the surviving carriers as the only
files still describing the retired combined.ww amalgamator as live:
m2wwi/m3sep headers claimed .wwi was dead code, four byteid carriers
carried dead cleanup of never-written .combined.ww intermediates, and
sepbuild's enumeration mirror plus lib_byteid's completeness scan
still skipped the retired artifact form (the same silent
accommodation just removed from both drivers — dropping it here
surfaced and flushed 39 stale untracked amalgamator outputs across
lib/, which the gates now reject loudly). Remaining mentions are
past-tense history or quoted diagnostics.
Every surviving carrier now owns its artifacts: checked mkdir/mkdtemp/
fopen acquisition, one all-exit cleanup funnel per carrier, ENOENT-
tolerant checked unlinks, exact-path deletion (rm -rf only for an
owned pid-keyed dir or a .sepwork beneath one), and cleanup failure
fails a passing carrier without overwriting its diagnostic. In the
same pass the carriers adapt to the driver contract this branch lands:
--sep and WW_PKGCACHE are gone, -S and the /tmp/ww_run_<pid> scratch
contract are asserted, and rows whose runtime or reject coverage moved
to test/wcc/data fixtures or test/lang @test owners are trimmed to the
byte/artifact/diagnostic observations only they can make.
Repair and adaptation ride together because most files interleave both
in the same hunks; splitting would manufacture intermediate carrier
states that never existed and cannot run against either driver.
94a of the C-mig2 split (rob rule-11): 13 Pattern-A gates that fed a
.combined.ww to w6c/w6c_ww now drive two --sep builds (ww / ww_ww) and
byte-diff the concatenated per-package .sepwork/*.s, mirroring #93's
convention. Lands pre-flip while combined.ww still exists as the
reversible safety net. Test-only; all 5 binary pins HOLD.
989_enumcap_run deferred to 94b (its decisive assertion is a combined.ww
content diff, not a .s diff).
The parser folded a qualified type pkg.Type into two different node shapes by position: declaration position collapsed it into one N_TNAME (resolved via the strrchr-leaf path), but literal position left an N_DOT chain that the struct-literal typeref handoff had no resolver arm for, so pkg.Type{...} rejected with "expected type expression".
Normalize the literal-position N_DOT chain into the same source-order N_TNAME the declaration path emits, reusing the existing resolver; no new checker arm. cstage flattens at parseprimary struct-lit handoff; wwstage (no token peek) folds dots in parsepostfix and normalizes there, guarding numeric tuple components and staying in the postfix loop so trailing ops still chain. Both stages emit identical N_STRUCTLIT(N_TNAME). Prereq for qualifying wcc syntax refs (#75).
