Separate import lookup from raw CLI target compatibility in both production drivers. Package scans and test-support edges now create directory nodes only, while unit composition emits only the owning package's sorted sources after direct export data. Document the Go 1.26.5 ownership evidence and retained single-file root boundary.
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.
Go compiles only _test.go files as tests; discovery now keys on the
_test.ww suffix alone. The line-leading-@test compatibility allowance
(noncanonical filenames admitted as test sources) is removed from both
driver stages and the coordinator. An @test declaration outside a
*_test.ww file is rejected loudly ("@test declaration outside
*_test.ww", wording byte-identical cs/ww) instead of silently running
under compose or silently dropping in a non-T build (#6). Tree audit
found zero real carriers; the two allowance fixtures flip canonical
(dep_test.ww, widget_test.ww). New pins: direnum attest-noncanon
reject row (both-stage stderr parity) and the coordinator
noncanonical_attest_rejected package row.
Go has no per-file test targets: the PACKAGE is the unit of testing
(`go test ./...`) and same-package test files compose together. The
59-target LIBRARY_TESTS fan-out (per-file -w workdirs, one Make rule
per suite) collapses to one line: `ww test -j $(JOBS) -w
out/wwbuild/wwtest-lib -I lib/ww lib/...` — the regex dir-route
precedent generalized. The lib/regex line and the per-file pattern
rule instance dissolve with it (test/lang keeps its own rule).
Measured before committing (-j4, strings edit row): old per-file
warm 4.7-4.9s; bare walk 5.2-5.6s — a real regression, so the
coordinator first gained the brief's persistent per-package workdir:
`-w DIR` on a package target forwards to wwpackage, which keys
DIR/<dir>_<pkg> per group and hands it to each inner `ww test -c`
build. Reuse stays entirely with the driver's existing
content-identity contract — the coordinator adds pure path policy,
no cache machinery. Both driver stages drop their package-target -w
rejects (forward instead); -w with -c stays rejected at the
coordinator (two ownership contracts). After: 3.9-4.0s on the edit
row, 1.0s warm no-op, 2.5s cold — faster than the old flow on every
row.
package_test's tree -w reject row becomes the positive contract
(cold+warm byte-stable stream, cs/ww same) plus the -c conflict
reject. libbyteid roster shape DECIDED: per-file fx entries stay —
every enrolled file is still standalone-buildable, so coverage is
byte-for-byte unchanged; the dir-mode entry form arrives only with
the B3 shared-helper split that first needs it. Docs: owner table,
target table, -w contract paragraph.
Go does not distinguish bootstrap observers from unit tests: an
in-process test is a unit test. 738 is pure parsefile calls (arena +
lexinit + parserinit, AST assertions, zero subprocess or artifact
claims) — the 200_parse class, misfiled among the residuals. The
fleet partition now reads six units / six bootstrap / three platform
and the residual class is empty; COMPILER_WRAPPER_SOURCES drops it
by the existing filter-out. Doc roster updated (also refreshes the
corpus prose to the current 1745/3490 pin and retires the stale
794-era paragraph).
The last Open-driver-work bullet. `-c -o <name>` replaces the fixed
<package>.test stem for exactly one package; the coordinator rejects a
multi-package fan-out ("cannot use -o with multiple packages", Go's
`go test -o` rule) and -o without -c is rejected at the driver
("needs -c for a package target" — a plain run executes from the temp
root, so a caller-owned name has nothing to name). Both driver stages
byte-identical wording; -S keeps its single-file-only reject.
package_test gains the contract row (naming, fixed-stem absence,
artifact runs, both rejects, both drivers); the tree-mode -o row's
pinned wording follows the contract.
Four ww tests carry the last eight native byteid carriers' assertions:
asmwindow (753 convwrap beta/main/alpha order + window polarity, 754
slice stride + negative scale scan, 755 amp-dot-idx four rows, 758
first-CALL-line extraction + tab-framed disp literals, direct
w6c/w6c_ww never ww build), freenoop (930 byte-id strengthened to
per-stream compare + negative 'free' grep), structabi (946 param/ret
MOVSD windows with polarity tables and SEND/RECV agreement), mangle
(989_m1mangle needles + concat byte-id, glob order strengthened to
byte-lexicographic). Dead want/stage_mask row fields documented, not
invented into runtime legs; the w6c_ww-absent skip gates drop because
the Make target declares the tools.
BYTEID_WRAPPER_SOURCES, its bins, and test-native-byteid are deleted —
the native byte/artifact partition is EMPTY (11 -> 0 this session);
docs counts move to 123 carriers.
25 renames (git mv, content untouched). _test.ww is what the package
coordinator's test detection and the sep loader's canonical exclusion
key on; the old *test.ww spellings survived only through the
line-leading-@test compatibility scan. Consumers updated in place:
LIBRARY_TESTS, the libbyteid roster, the 901/974/975/976 carriers that
copy or invoke these files, and the check.c/check.ww + path/ftos
comments that cite them. Closes the open-driver-work migration bullet.
test/byteid/wwi_test.ww carries every assertion of both carriers: the
M2 producer gate (ascii/strings/getopt driver-combined positives with
byte-id + wwdump -a re-parse, the synth decl-kind/type-node sweep with
the #47 @symbol round-trip, the #48 types export-def gate, and the
negative private-nominal leak with both-stage identical reject
diagnostics), plus the #11 wwileaf decl-less-leaf rows (package-line
leaf, cross-stage .wwi byte-id, importer resolution + .s byte-id).
Byteid carriers 10 -> 8; docs counts move; the byteid ww target gains
the wwdump prereq its re-parse legs invoke.
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.
A -w DIR workdir replaces the fresh .sepwork scratch with a caller-owned
persistent package-artifact tree. A package is reused only when its
freshly composed unit byte-equals the committed unit and byte copies of
the compiler/assembler recorded in the dir equal the live tools — pure
content identity, no mtimes, no hashes, every decision reproducible
with cmp against plain files. Recompiles stage at .new names and commit
by rename, unit strictly last, so an interrupted build forces a
recompile and can never leave a committed unit vouching for uncommitted
artifacts; .o/.a additionally reject zero size (ELF/ar are never
empty), while .s/.wwi accept legitimate empties (FFI-only rt). A mode
stamp pins the -T/-S shape and the artifact protocol revision. Classic
scratch keeps its exact acquire/refuse/cleanup contract; run rejects
-w; dir-mode test rejects -w; both driver stages implement identical
behavior and wording.
