fold-2 chunk C3 (drew's Fam8-13 plan): 8 alias value-row C drivers, 205 rows
re-homed with zero loss -- 177 value -> 8 test/lang/alias_*_test.ww @test
row-tables; 16 reject -> runww //ww:error carriers (both stages reject);
3 cs!=ww value rows -> 2 *_runonly_test.ww (T1, byte-id-excluded, #60/#81);
9 irreducible asymmetric rows -> slim C pins, each ticket-cited and
mutation-proven non-vacuous:
- accept amplen1/2,ampcap2: cs runs / ww rejects 'unsupported address-of
shape' (#96)
- cgen_b5 g73_heapfill: cs!=ww .s + ww link-fails on self-contained alloc;
compile-smoke pin (#24)
- cgen_b6 fsarg2_bound: both reject, different msgs, each vs the correct
stage (#271/#165 cs vs #272/#276/#277 ww)
- emit_b7 slc/slcstr/slctag _2lvl + slc_plain_ctl: slice-literal static-init
divergence (#120/#29-kin, ken-d2-oracle)
4 fully-migrated drivers deleted, 4 slimmed-in-place to hold only the
irreducible pins. LANGBYTEID floor 74->82 (8 new byte-id @test files); test
count 388->384 (4 deleted; 4 slimmed kept). do-not-auto-batch files not in
Fam10.

* 944_alias_cgen_b5_run — SLIM CARRIER (#5-C3 alias fold-2). The 27 K_RUN value
|
|
* rows migrated to test/lang/alias_cgen_b5_test.ww (@test, cs==ww byte-id); the
|
|
* symmetric K_BUILDERR rejects (fill0_ctl, fill2_loud, g73_static_str) to
|
|
* test/wcc/data/alias_{fill0_ctl,fill2_loud,g73_static_str}/case.ww runww.
|
|
*
|
|
* What survives here is the one IRREDUCIBLE K_COMPILES row: both stages
|
|
* FRONTEND-compile (w6c / w6c_ww → .s, rc 0) but the asm diverges (the ww
|
|
* deref-field READ carries the #24 field(SB) leak) so run + byte-id cells are
|
|
* unavailable, and a full `ww build` can't link this self-contained `alloc()`
|
|
* case (no rt malloc) — runww //ww:compile links and so cannot host it. The
|
|
* pin is the ABSENCE of the pre-c2 cstage #73 fatal at the heap struct-lit
|
|
* str-arm fill; the ww-side leak rides task #24. Compile-smoke only.
