fold-2 chunk C5 (drew's Fam8-13 plan), the highest-risk chunk: 21 match/tagged
value-row C drivers re-homed. 20 -> test/lang/*_test.ww @test row-tables + 12
runww //ww:error carriers (both stages reject). The global-tag cluster
(globtag*/globstructwiden/taggedderefstore/...), which sits on the #15/#17
global-ptr fix, was empirically probed byte-id CLEAN -- the predicted hotspot
surfaced ZERO fresh cs!=ww. Carves: variant_chain_b95 #81 -> _runonly (genuinely
diverges at HEAD); callret_bound277 #277 -> slim C pin (cs-runs/ww-rejects),
mutation-gated. 929_tagged_memarg kept whole (SSE-ABI asm conformance). 19
drivers deleted, 944_variant_chain slimmed to the #277 pin.
The match-on-tagged-struct-field divergence (former #26) probed RESOLVED for all
its cited shapes (938 voidstr_field/recursion_torture, tagnorm dedup_match all
byte-id cs==ww + value-correct) -- closed no-reproducer-at-HEAD, attribution to
#15/#17 INFERRED. Those rows migrate as normal byte-id @test and serve as the
REGRESSION SENTINEL for the inferred close (a resurgence trips the gate).
LANGBYTEID floor 93->113; test count 374->355 (19 deleted; 929 + 944_variant_chain
kept). do-not-auto-batch (926_tagscr/940_global_sret/940_str_forrange) untouched.
fold-2 chunk C2 (drew's Fam8-13 plan): 14 tuple value-row C drivers migrate to
15 test/lang/*_test.ww @test row-tables (the +1 is 954_tuprecv, slimmed not
deleted -- its value rows split out while the asserttyped-stamp dimension stays
as a carrier-split C pin, mutation-proven non-vacuous). Reject rows move to 32
test/wcc/data/*/case.ww //ww:error carriers (runww asserts the substring in
BOTH stages). The test-lang byte-id (LANGBYTEID) gate gives cs==ww automatically
and is strictly more sensitive than re-running the wwstage leg; floor 59->74.
Tuple surfaced zero cs!=ww as the plan predicted -- no value-only carve. The 945
trio folds in here; 940_global_sret / 940_str_forrange / 926_tagscr untouched
(routed to drew per-file). Test count 402->388 = the 14 retired drivers.
fold-2 chunk C1 (drew's Fam8-13 plan): 960_opaque_decl_run.c and
962_opaque_assign_cast_run.c were value-row C drivers. Migrate their 3+3
cases to test/lang/opaque_decl_test.ww and opaque_assign_cast_test.ww as
@test row-tables. The test-lang byte-id (LANGBYTEID) gate gives cs==ww
automatically -- 960 was cstage-only-run before, so this strengthens it.
Both byte-id clean, no cs!=ww carve. Retire the 2 C drivers (LANGBYTEID floor
57->59) and repoint a dead comment ref in lib/sort/sort.ww. 961_opaque_guards
(reject/guards) stays in C -- fold-3 territory, not in the Fam12 fold-2
worklist.
Reading gp.f through a module-global pointer miscompiled in BOTH stages,
differently: cstage classified gp as a local at boff 0 and derefed BP
(MOVQ (BP),BX), wwstage collapsed gp.f to an undefined global symbol f
(MOVQ f(SB)). Both now load the pointer value from the global's data slot
before the field offset, converging on MOVQ gp(SB),BX; MOVQ off(BX),AX.
cstage mirrors the #6 store decline; wwstage gains a global-ptr arm and
shares a cgptrfieldload helper with the local arm.
Fused, not split: the two stages must emit byte-identical asm, so a
one-stage commit would fail the byte-id gate. Sibling byte-divergences
filed: #16 (chained-spine gp.x.y), #17 (>32B tagged word-order).
Test: table-driven 689_globptr_field_read_run (24 rows, runtime + byte-id).
A module-global pointer's field store/compound (`let gp:*S=nil; gp.f += 5`,
`gp.in = Inner{...}`) SEGV'd in cstage: the enumerated N_DOT-lhs arms load
the base pointer with `MOVQ boff(BP),BX`, valid only for a LOCAL ptr slot,
but a module-global ptr has no local slot (localfind=0) so it dereferenced
the saved BP. wwstage was correct -- it routes these through its F6
cgplaceaddr resolver (its dedicated arm is scalar-`=`-only by design,
#60/#61). The byte-id gate was blind (no global-ptr compound in the
bootstrap corpus) and the deferral note was stale: this is a live cs!=ww
divergence with wwstage as the oracle.
cstage already has an equivalent assign-resolver (cgen.c ~7488) that emits
byte-identically to wwstage's F6 route, but the enumerated arms intercepted
the global case first. Fix (align cstage UP, cstage-only): two precondition
entry-guards decline a module-global `*struct` base for the compound +
non-scalar-field cases so they fall through to the resolver. Plain-scalar
`=` stays in the enumerated arm (its #47 fix already matches wwstage). The
decline and resolver accept-sets exactly partition the global-base
N_DOT-lhs space (no gap, no overlap); tagged/float field stores now both
loud-stop symmetrically (were SEGV'ing). The discriminant keys on
localfind-presence + let_islet, so a param at offset 0 stays local.
New both-stage + byte-id test 689_globptr_field_store_run covers offset-0/8,
compound, struct/str field, chained gp.x.y, indexed gp.a[i].f, with local +
offset-0-param controls. The field-READ path is independently broken in
both stages (filed #15). make clean && make test: all 403 passed, byte-id
990-996 green.
The 9 Makefile recipes that build selfhost/cmd/<tool>/main.ww (5 primary
$(BIN)/*_ww + 4 nocc bootstrap) passed no -o, so the compiler's scratch
followed the SOURCE stem and left selfhost/cmd/<tool>/main.sepwork in the
tracked tree (the binary was mv'd out; the .sepwork dir stayed behind).
Each recipe already cd's into a gitignored out-of-tree dir before building,
so a uniform `-o main` makes the scratch follow the OUTPUT stem (cwd) out
of the source tree; the binary still lands at cwd `main` and the existing
`mv` lines are unchanged. Same intermediates-follow-output principle as the
T3 -o redirect (rule 14).
Carved from #8 by unanimous advisor ruling as its own bisect-clean commit.
make clean && make test: all 402 passed, zero in-repo .sepwork, zero /tmp
scratch.
wwi_emit took the .wwi `package` leaf from the first primary decl's module tag;
a fully empty primary module body (zero decls) had none, so the leaf stayed the
literal default "main" and the importer rejected it ("package main does not
match import path <leaf>"). The module identity is only available at parse time
(curmod is overwritten by imported //ww:module sections before emit), so stamp
the primary path onto the N_FILE node (TK_MODULE and TK_MODRESET rp!=NULL sites,
only-if-empty so a bare-reset `package main` root stays "main") and, when the
decl-scan finds no leaf, fall back to that stamped path. Symmetric cstage+
selfhost; both detect scan-miss via the same found-flag so the emitted .wwi
stays byte-identical.
Regression: test/wcc/989_wwileaf_run.c, table-driven over {empty body,
comment-only, nested a.b.c} decl-less shapes, non-vacuity proven.
A torn producer write (e.g. disk-full mid-copy) could leave a 0-byte P.wwi or
P.o in out/.pkgcache under a self-consistent key; cache_lookup checked only
existence, so every later build HIT and served the empty artifact forever
(silent serve-wrong). Reject size==0 on both sides, symmetric across stages:
store refuses to commit a 0-byte temp before the key write, lookup treats a
0-byte cached artifact as a MISS so existing poison self-heals on re-derive.
A valid .wwi/.o is never 0 bytes, so the guard cannot misfire.
Regression: test/wcc/989_pkgcache_poison_run.c, table-driven over
{poison P.wwi | P.o | both}, non-vacuity proven by guard-neuter.
BUG-A #9: when an empty/export-less inlined module body produces `//ww:module <p>` immediately followed by `//ww:module-reset` in one skipws run, lexnext drained TK_MODRESET first then emitted the STALE TK_MODPATH past the reset boundary, re-binding pathmod=<p> so the root `package main` was validated against <p> -> wrong reject. Fix clears the pending modpath at the reset-RECOGNITION site in skipws (NOT lexnext drain): cstage l->modpath=NULL after both l->modreset=1 (cmd/wcc/lex.c); selfhost l.modpathset=0 after all three l.modreset=1 (lib/ww/syntax/lex.ww). Symmetric (rule-10): identical token streams, bootstrap byte-id holds. The normal RESET-then-PATH boundary is unaffected (clear is a no-op when no path is pending). Pin: test/wcc/989_modresetadj_run.c feeds the raw composed adjacency to w6c+w6c_ww (accept + byte-id), red-path-proven (reverting a clear reddens it). A separate wwi-producer defect surfaced (decl-less .wwi defaults to 'package main') filed as #11; not touched here.
#152 link-the-let-before-its-init miscompile (miscompiled IDENTICALLY on both stages, so byte-id 990-997 was blind; only a runtime value check catches it). Lifted the run fixture into test/lang/letshadow_test.ww (primitive @test value pin; byteid-eligible — symmetric, cs==ww). byteid floor 56->57. Closes the fold-3 #7 umbrella (last C test twin retired).
#154 cstage-only str== global-header miscompile (str== fast-path read the global str header off BP+0 instead of name(SB); byte-id 990-997 blind to a runtime-value miscompile). Lifted the run fixture into test/lang/strglobeq_test.ww (primitive @test value pin; byteid-eligible — post-fix cs==ww). byteid floor 55->56.
949_dotfield_compound + 949_idxfield_compound are one bug class (#133-lineage compound-assign load-op-store on field lvalues; #34/#33, #263 carve-out) sharing the combine + hard-error path, so the two C carriers fuse into one commit: 26 value rows -> test/lang @test row-tables (primitive-only asserts), 8 reject rows -> runww //ww:error dual-stage carriers. byteid floor 50->52.
#133 indexed-scalar compound-assign. The 21 rows split by observability:
18 value rows -> test/lang/idx_compound_test.ww (one @test fn each,
primitive-only asserts, slot-poison + neighbor-unchanged read-back);
3 reject rows -> test/wcc/data/idx_compound_{float_indexed,str_indexed,
chained_ptr_float}/case.ww as //ww:error, asserting BOTH stages reject on
the shared diagnostic body (cstage's leading prefix excluded). The C twin
is retired; its coverage is a strict superset of the original rows.
First reject-bearing fold-3 migration -- validates the runww dual-stage
home end to end. LANGBYTEID_EXPECTED_MIN 49 -> 50.
test-run drives runww.ww over the test/wcc/data/*/case.ww behavior and
//ww:error cases, but was not a prerequisite of any aggregate, so the
reject surface was ungated. With runww's arm now dual-stage, gate it.
Added to the pre-push `test` target only -- not test-unit, not the
test-commit content-key tier. runww execve's its children with nil envp,
so a WW_PKGCACHE override cannot reach them; they fall back to the default
out/.pkgcache that $(TESTS) and the byte-id gates also use. A normal
prereq would let make -j overlap test-run with those writers, so test-run
carries an order-only prereq (| $(TESTS) test-lang test-lang-byteid) and
is scheduled strictly after every default-cache writer. No cache
isolation is added: it would be inert under nil envp, and the ordering
prevents the race.
True per-run cache isolation stays blocked on an os envp() forwarder.
Continue fold-2: migrate the struct-by-value / sret round-trip family from
bespoke build+run C twins to test/lang @test, retiring each twin in the same
commit. Runtime coverage MOVES from $(TESTS) to test-lang (T1 runs+asserts via
`ww test`) + test-lang-byteid (T2 keeps cs==ww .s byte-id); the $(TESTS)
headline drops 6. Every assert is a primitive int/u8/bool comparison (no
fmt/strconv in the assert path); each returned struct/tuple FIELD is asserted
individually so a dropped/mis-offset/over-wide word FAILS. 46 @test cases, a

all 6 new files are byte-id cs==ww (no fold-5 divergence surfaced). Bump

Continue fold-2: migrate the pointer-deref / narrow-load / pointer-array-stride

asserts via `ww test`) + test-lang-byteid (T2 keeps cs==ww .s byte-id); the
$(TESTS) headline drops 5. Every assert is a primitive int/bool comparison with
a width-preserving (`==`) sink so a stale high half or wrong stride FAILS; the
narrow-signed rows route through an `: i32` cast against a 64B-widened literal
to force sign-extension onto the load. Each .c row maps to one inline @test fn
(50 cases total, strict superset of the C rows):

The two sibling .c (949_dotbase_addr_slice_run, 944_alias_def_addr_run) stay in
$(TESTS): the first is run-only byteid=0 (#254 cs!=ww rows), the second carries
a LOUD rule-7 reject row — both routed to fold-3 (task #7). Bump

glob_ptr_field keeps only the .c's offset-0 row: an added non-zero-offset row
(gp.g=9) surfaced a cs!=ww divergence (cstage folds the offset into the store
displacement `MOVQ AX,8(BX)`; wwstage emits `ADDQ $8,BX; MOVQ AX,(BX)`) — a
latent global-*struct-pointer field-store divergence beyond the .c's coverage,
reported for the backlog, not carried here. Bump LANGBYTEID_EXPECTED_MIN 35->38.
Continue fold-2: migrate the #73 whole-struct field-copy ragged-tail test from a

preserved, the $(TESTS) headline drops 1 (422->421). All four rows are pure
value-rows (no reject rows): each poisons `mark` at the inner struct's natural
offset, copies, then asserts every field back with primitive int comparisons, so
an 8-byte MOVQ that over-writes the ragged-tail successor FAILS.
989_structcopytail_run.c -> structcopytail_test.ww (tail2/tail6/tail7 ragged-tail copy preserves mark; ctl8 8-aligned control)

each .c proved, so the C twins are pure-deletion redundant. Each retired
family below names the T1 twin that now carries its value obligation; every
twin was verified to READ the value/slot and ASSERT it (not merely compile),
including the pre-zeroed-slot families (it poisons cap!=len / spoils the base

make test and test-commit the runtime value coverage that the test/wcc
.c twins currently provide, the precondition for retiring those twins.
Kept out of test-unit (inner loop stays fast) and run-always in
test-commit (NOT in the content-key skip set — caching a value gate
reintroduces silent-skip-of-value). Isolated WW_PKGCACHE=$(OUT)/langcache
so concurrent make -j cannot corrupt the default cache.
Compiles every test/lang/*_test.ww twice through the same cstage ww
orchestrator swapping only the frontend (WW_W6C = w6c vs w6c_ww) and
asserts every per-package <pkg>.s (incl the synth-main __root.s) is
byte-identical. This is the rule-10 stage-symmetry gate test/runww.ww
reserves as T2. .s-only (Q3); .o/.wwi are 991/992's surface. Distinct
WW_PKGCACHE per leg, both caches+sepworks wiped per file. Recipe is
parameterized over an input-class (file-list + build-verb); only the
test/lang class ships now, fold-6 slots in build --sep for selfhost/data.
Wired into make test (pre-push) only, not test-commit/test-unit.
