Unblocked by the package-mode ruling: same-package test files now
compose everywhere (coordinator dir-mode owns test-library and the
libbyteid dir entry owns byte identity), so the per-file standalone
constraint is gone and Go's stdlib layout applies directly. The
15-banner strings_test.ww monolith dissolves into per-ref-file
family files — dup, concat, trim, sub, utf8, iter, tokenize
(tokenize+splitn+cut, all of ref tokenize.ha), pad, replace — plus
helpers_test.ww holding exactly the one cross-family helper (streq),
Go's shared test-helper idiom. Pure moves; family-local helpers
(expect_str_token et al.) stay in their family file. Leading banners
that merely restated the filename dropped; 6 interior sub-family
boundaries remain. lib/ census 141 -> 132.
libbyteid gains the dx() dir-mode entry form decided in B2: compose
every *_test.ww under moddir exactly as pkgcombined does
(module-reset separators, byte-lex order) and byte-id the composed
root through both driver stages. The five per-file strings fx
entries retire into one dx("lib/strings") — every source line they
covered is inside the composed unit, and the completeness scan still
keys the module. NENTEXPECT 60 -> 56.
Recorded, not split: fmt_test's 13 banners are scenario groups over
the one fprint surface and ref/hare/fmt itself keeps a single
+test.ha — a print/wrappers split would fight the ref; memio stays
per the standing ruling (everything ww ports lives in ref
stream.ha).
