ww: lib tests run via -T test mode; bare mains retired (closes @test conversion)
'ww test' gains the istest build path (-T injection in build_one/ buildone) and do_test/dotest accept -I, mirroring do_run - both twins. The 35 converted lib tests drop their interim bare mains (-T synthesizes the entry from @test fns and rejects a user main); their 35 C run-drivers flip 'ww run' -> 'ww test'; 989_lib_byteid compiles lib tests under -T (8 user-main probe fixtures stay non-T, gated on the fixture field). Abort-on-first-failure stands until the deferred record-and-continue harness lands with the multi-package arc. |

cmd+selfhost+lib+test: directory-as-module enumeration in driver (#22)
Replace the cmd/ww + selfhost driver's file-walk import resolver with true directory enumeration. `import encoding.utf8;` now finds the lib/encoding/utf8/ directory and concatenates every *.ww file in it (excluding *test.ww and the driver's *.combined.ww artifacts) in byte-wise sorted order, instead of just finding the single lib/encoding/utf8/utf8.ww file. Mirrors Hare's hare/module/srcs.ha:183 _findsrcs minus tag handling. Lookup order in both stages: (1) <dir>/<dot-as-slash>/ as directory → enumerate. (2) <dir>/<dot-as-slash>.ww as file. The legacy <dir>/<name>/<name>.ww shape from #18's retained divergence is dropped per rule-9 Hare-fidelity — Hare has no foo/foo.ha fallback; a module IS the directory. Symmetric across cstage (cmd/ww/main.c via opendir+qsort+stat) and wwstage (selfhost/cmd/ww/main.ww via existing lib/os.getdents64 + os.stat — no new lib/os surface needed; the rundirtests() walker in main.ww from #18 was the model). Bootstrap ww2.s==ww3.s==ww4.s byte-identical post-change. Bundling justification (rule 11): strict-same-package validation is bundled because the failure mode is dir-enum's own (a non-dir-enum compilation unit cannot trigger mismatch across enumerated files). The natural enforcement site is the driver — the parser can't distinguish dir-enum concat from file-walk concat. Both stages peek each file's first `package <name>;` line in expand_dir / expanddir and exit(1) on mismatch with a precise error pointing at the offending file. Hare's hare/module/srcs.ha:131 has the same constraint via its README gate. Other half of #23 (strict missing-package error tightening — 63 inline-source test wrappers blocker) stays deferred per its filing. Parser side (cmd/wcc/parse.c parseuse + lib/ww/parse/decl.ww parseuse): n->str now carries only the LEAF identifier from a dotted import. With the driver translating the full dotted path to a directory walk, the checker only needs the package bareword (last component) for the N_USE → decl disambiguation walk in check.c's src_imports / decl_mod. Mirrors Hare's `use encoding::utf8;` → `utf8::name` semantics (ref/hare/hare/ast/import.ha:7). Migration: lib/ww/sym.ww drops `import typ; import ast;`; lib/ww/parse/parse.ww drops `import expr; import stmt; import decl;`; lib/ww/lex/lex.ww drops `import tok;` — all sibling imports auto-resolve via the new dir-enum when callers import the package directory. lib/strings/, lib/encoding/utf8/utf8test.ww migrate `import utf8;` → `import encoding.utf8;`. Makefile drops -I lib/encoding/utf8 stopgap from wwdump_ww + w6c_ww. Seven test wrappers (700_e2e, 966_strings_run, 970_fmt_run, 971_log_run, 972_fnmatch_run, 982_getopt_run, 990_selfhost) and 995_self_rebuild drop the -I lib/encoding/utf8 runtime stopgap. Tests: new 737_direnum C wrapper + test/wcc/data/direnum/ fixtures pin (a) cross-pkg multi-file dir-enum build at runtime (both stages must succeed) and (b) strict-same-package mismatch error (both stages must surface "differs from" + exit non-zero). 738_module_decl gains row 6 pinning the n_use->str leaf-only storage post-parser change. Retained workaround at selfhost/cmd/ww/main.ww expanddir loop: `names[i][k]` nested-deref-then-index split into `let nm: *u8 = names[i]; nm[k]` because wwstage cgen miscompiles the chained form (treats inner u8 element as 8B sizeof *u8 instead of 1B sizeof u8: extra MOVQ $8 + IMULQ on the inner index, MOVQ instead of MOVZBQ load). Inline rule-8 WHY comment cites task #24 (wwstage cgen chained-index inner element size on **T). Two-step form routes through the bare-pointer index path which both stages handle byte-identically. Class A wwstage cgen UNDER (chained-index inner element size on **T) surfaced first time the codebase exercises the **T[i][k] shape via enumeratedir() — corpus-coverage-blind landmine pattern, same family as the trio (#27/#28/#31) from STATUS-5. 112/112 ok. ww2 == ww3 == ww4 byte-id holds. |

lib/strings+test: Hare port (dup/concat/trim/index/contains/has{pre,suf}fix/compare/utf8)
Hare-faithful index/predicate family per ref/hare/strings/{dup,
concat,trim,index,suffix,contains,compare,utf8}.ha. Non-variadic
subset (concat 2-arg, trim single-rune, contains single-needle)
pending task #16 — cstage variadic-pack drops .len on multi-field
element types; ship the Hare-faithful single-arg shape now, file
the variadic upgrade as follow-up. `sub` follow-up filed as #29
(commit 2 with iterator + utf8.chars relocation).
Surface: dup, concat, trim/trimprefix/trimsuffix (single rune),
hasprefix, hassuffix (both with (str|rune) sum needle),
byteindex, rbyteindex (both with (str|rune) sum needle),
contains (single str needle), compare, toutf8, fromutf8_unsafe,
runebytes helper. (str|rune) match arms route the rune via
utf8.encoderune into a [4]u8 scratch then bytes.index/rindex —
drew-devault's directive for clean Hare-fidelity over invented
ASCII-only rune-byte arms.
byteindex / rbyteindex rune-arm semantic correction —
corpus-coverage-blind unmask. Pre-existing impl scanned for
`r: u8` (broken for all rune values >0x7F since strings.ww first
landed; no caller exercised it). Replaced with utf8.encoderune-
based scan via runebytes helper. Severity-marker: silent
wrong-result for any non-ASCII rune needle, masked by zero
in-tree callers until lib/strings + utf8 chain pulled the shape
in.
Build-system propagation: lib/strings depends transitively on
lib/encoding/utf8 (via byteindex's rune arm). cmd/ww driver's
locate_import_in (cmd/ww/main.c:85) walks `<dir>/<name>.ww` and
`<dir>/<name>/<name>.ww` only — `use utf8;` doesn't find
lib/encoding/utf8/utf8.ww without explicit `-I lib/encoding/utf8`.
Propagated through 5 wwstage-tool Makefile targets + 7 test
wrappers + test/wcc/995_self_rebuild.c sprintf lines. Task #17
filed for the principled resolver fix (subdir walk vs Hare's
qualified `use encoding::utf8;` notation).
This commit chain (#15 strings) surfaced 7 cgen bugs during
landing: #16 cstage variadic-pack, #17 resolver nested-paths,
#27 aliaslookup leaf-collision, #22 zero-init !void/void-alias
let-decl, #15-cstage retscr SSoT name, #24 composite CALL return
as composite arg, #28 N_DOT calleeparams. All blocking ones
fixed (#16/#17 deferred-with-stopgap, others fixed in their
respective commits). Pre-flight + stop-and-surface discipline
held throughout — no workarounds shipped in stdlib.
Tests:
- 966_strings_run drives lib/strings/stringstest.ww via ww run.
15 @test fns: dup (alloc, multibyte), concat (empty, lopsided,
multibyte), trim/ltrim/rtrim incl. 4-byte rune U+1D68A,
hasprefix/hassuffix with (str|rune) incl. multibyte,
byteindex/rbyteindex both arms 1/2/3/4-byte rune coverage,
compare. Cited from ref/hare/strings/+test.ha where vectors
apply.
100/100 ok. 995_self_rebuild stays green (ww2==ww3==ww4 byte-id).

lib+test: add fnmatch over Hare sea-of-stars
Port of ref/hare/fnmatch/fnmatch.ha. Public surface mirrors Hare:
`flag` enum (NONE/PATHNAME/NOESCAPE/PERIOD) and `fnmatch(pattern,
string, flags) bool`.
Algorithm is the three-phase sea-of-stars (also used in musl):
exact-match the prefix before the first `*`, exact-match the tail
after the last `*`, then greedily match each star-delimited middle
segment with backtrack on inner failure. No exponential corner —
each star anchors a "match found" at strictly increasing positions.
Bracket expressions: Hare-strict — `!` for negation, `^` rejected
as invalid; `]` as first member legal, trailing `-` literal, all
12 POSIX classes ([:alnum:] … [:xdigit:]) via direct streq + the
ascii.is* predicates.
Divergences from Hare (documented in fnmatch.ww docblock):
- byte-indexed cursors in place of strings::iterator (no UTF-8
rune iter yet); ASCII-only meaningful, multibyte matches
byte-identically. Graduates "in one go" per lib/CLAUDE.md
when the language stack grows rune iteration.
- invalid pattern collapses to `false` at the public boundary
(Hare's `b is bool && b: bool;`); a try-shaped diagnostic
entry can be added later without churning the surface.
- tail-match uses a forward cursor at `string.len - cnt`
instead of riter/prev — same byte sequence either way.
Test fixture follows the project's helper-per-row table-driven
shape (precedent: lib/encoding/base32/base32_test.ww). 8 @test
fns clustered by feature (basic / brackets / ctype / period /
noescape / musl_basic / pathname / combined), ~95 rows total
adapted from Hare's +test.ha plus musl-derived edge cases.
Wired as 972_fnmatch_run alongside 970_fmt_run / 971_log_run in
the stdlib-runtime band.
