The test/object observers parse assembler/linker artifacts; the
readers reinterpret readfile's byte str and route through endian's
canonical legetu* instead of re-deriving the bit math.
test/testenv (package testenv) is the shared plumbing for ww-native
test drivers — subprocess launch with captured output, file IO, string
search, byte-sorted directory listing, scratch ownership — lifted from
the proven package_test.ww idiom; a utility, not a framework.
test/byteid/libbyteid_test.ww carries every assertion of the retired C
carrier: the 44-entry roster (fixtures + sentinel-guarded import probes
+ the zero-dep root-only build), both-stage sep builds with the
resolved-unit proof, per-package .s concat compare with the empty-concat
guard, the ID/DIVERGE/WWREJECT pin discipline, and the lib/ corpus
completeness scan (negative-verified against a planted un-enrolled
module). Concat order strengthened from shell-glob to explicit
byte-lexicographic. The roster fills by cursor-driven field writes
because append() rejects struct-call-result sources (#34).
Byteid carriers 11 -> 10; docs counts move; test-byteid runs the ww
test via the wwtest/ pattern with WW_TEST_REPO.
