Make the schema-1 transcription mechanically consistent before the protocol freeze: restore compiler-protocol identity, use the typed native-contract record identity, distinguish encoding and path classes, and close the package artifact kinds. These corrections must land together because one exhaustive IDL cannot encode the prior conflicting rules.
Three same-cluster robustness holes. enumeratedir treated a failed
getdents64 (r<0) as EOF: a mid-walk error silently truncated the
package source list, and a first-read error was misdiagnosed as
"directory contains no WW package sources" -- it now routes the
caller's "cannot read directory" arm. run_test_bin's waitpid had no
EINTR retry and its return was unchecked, so an interrupted wait
left status==0 and reported a false test PASS (the do_run twin
already retried). The coordinator's pkgskipspace now also skips
/* */ before the package clause like the driver's sep_skip_space --
a source opening with a block comment built under ww but failed
coordinator discovery.
The TODO(#11) silent-accept of `for (let (a, a) .. xs)` rested on a
stale premise -- resolvewalk has per-block scopes since #53 and IS
the live w6c_ww checker pass. Bindings now install in a per-LOOP
scope (the N_MCASE pattern), so a duplicate name within one pattern
errs "redeclared in same scope" (cstage parity via stamptuplebinds'
scopedefine-nil check) while sequential same-name loops stay legal.
kwtab restores its stated alphabetical order (`import` before `is`,
both stages, kinds swapped in lockstep with names).
Four seams from one review cluster, all landing on the same checker
files; gates ran on the union (rule 11 body).
?-subset: the wwstage walk compared `...spread` ALIAS nodes on both
sides of the error-subset check, falsely rejecting a spread-carried
error return (`(i64 | ...errs)`, cs-accept/ww-reject) — both sides
now flatten like trycountvariants (cstage Tparams are pre-flattened
at type level).
Multi-let/multi-assign: the tuple gates keyed on the RAW rhs kind,
rejecting a NAMED tuple alias (`type pair = (i64,i64)`; cs clean-
reject, ww asserttyped stop) — both stages chase per #99 alias
transparency, wwstage rettupleof peels the alias so cgmassign keeps
the str element's len/cap stores, and the catA massign-alias error
pin re-rules to a run fixture. The N_MLET diagnostic also printed
its operands swapped (elem/declared reversed vs its wording).
Yield: match_yield_type didn't descend into N_SWITCH, so a yield
inside a switch arm typed the match void and dropped the value
(both stages); and a stray yield outside any match arm reached cgen
unchecked — both stages now gate on a match-arm counter (the
c->loops discipline).
