test: migrate Fam10 alias value tests to @test, carve divergences to pins (#5-C3)

Browse Source 
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 — #5 alias arc F2b (B5 train): cstage cgen
* helper + funnel internalization through type_chase_named (c1), the
* #73 tripwire graduation (c2), the #89 cgreturn return-position widen
* (c3) and the #93 deref-index pointee chase (c4). All cs-only: every
* graduation is a DIVERGE→byte-id flip (cs aligns UP to ww's already-
* chasing asm); zero selfhost/lib bytes move across the train, so the
* _ww binaries stay bit-identical (the crossing detector).
* 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.
*
* Row sources are ken's B5 oracle probes (/tmp/ken_b5/src,
* .ai/ken-b5-oracle.md + its c1-BOUNDARY ADDENDUM) and the c3/c4
* seeds (/tmp/ken_na, kb4).

* g93_l2_local | `(*p)[2]` over *arr2 (arr2=arr= |

* g93_def | def twin: `(*p)[2]` over &D, D a |
* | 2-lvl alias def array (kb5_def93) | 0/0
* g93_1lvl_ctl | 1-level pointee control — held 0/0 |
* | byte-id throughout | 0/0
*
* K_RUN rows build+run BOTH drivers (cs exit==cswant, ww exit==wwwant)
* and assert cstage/wwstage asm byte-id. K_RUN_NOID asserts both run
* cells but waives byte-id — cite the blocking task/commit at the row.
* K_CSERR_WWRUN is the dual-cell bound kind (the inverse of
* 944_alias_accept_run's K_RUN_CS_WWERR): the cstage build must FAIL
* with experr AND the wwstage build+run must exit wwwant — both cells
* asserted so neither the cs loudness nor the ww behavior can drift
* silently while the cited task is parked. NNN<950, self-contained
* /tmp sources, no imports (944 precedent).
* 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.

* 944_alias_decl_order_size_run — #62 rider (alias arc pre-F1): type-

* to resolve typedecl bodies in file order with an eager under->size
* copy, so any body referencing a typedecl declared LATER read its
* size-0 placeholder and baked it in: alias size 0, tagged-union
* maxsz 0 (the F0 m5_match $48-frame under-allocated box), struct
* field offsets collapsed, array element stride 0. wwstage (demand-
* driven tinfofornode) was order-independent on every row — the
* measured-sound side cstage now mirrors via resolve_typedecl's
* resolve-on-first-reference. Oracle: ken /tmp/ken_62_oracle.md
* (size((void|ali)) = 8B tag + roundup8(chased member size); every
* behavior indistinguishable from the (void|base) spelling).

/*
* 944_alias_global_decl_run — g-fold (#77 + #78 fused): alias-typed
* GLOBAL declarations, both stages. The decl/emit dispatch was
* alias-blind on both sides:
*
* cs (#78): the let_* helper family (let_emit_size + the five kind
* predicates, cgen.c) single-peeled — a 2-level alias chain (or ONE
* user alias over a named struct) left the type TY_NAMED, so the
* global was never registered, no DATA was emitted, and reads fell
* to the frame-local path at offset 0: silent saved-BP reads (garr2
* exit-wrong, gst1 SEGV, gstr2/gsl2 silent-wrong). The routed-to
* DATA emitters re-peeled at entry and return-0'd into the silent
* skip (condition-3 members, enrollment ruling in
* .ai/rob-gfold-spec.md).
*
* ww (#77): emitletdataw's array gates + letpreintern's array leg
* keyed on the UNCHASED N_TARRAY tnode — an alias-typed global's
* N_TNAME matched no arm and the skip-policy ate the decl: loud
* `w6l: undefined reference to main.g` on every alias-global ARRAY
* row. Fix: ONE tichase at the dispatch entry (dti), array gates +
* emitarraydata read it.
*
* THIS TABLE IS THE PERMANENT GUARD, not scaffolding: the global decl
* path is lint-invisible to the future peellint — the ww side was a
* NO-PEEL consumer (zero `.under` tokens; nothing for a peel-shape
* lint to flag), and the cs helpers now spell the one chased accessor.
* Only a runtime+byte-id row pins this behavior.
*
* Train trajectory (two commits, one gated train; per-leg states were
* probe-verified, banked /tmp/implG_probes.md):
* pre-G1: garr2 cs EXIT-WRONG / gst1 cs SEGV / gstr2+gsl2+gstlit cs
* silent-wrong / gsc2+gflt2 cs loud / ww array rows link-ERR
* post-G1 (cs half): every cs row runs 0; ww array rows STILL
* link-ERR (loud, documented)
* post-G2 (ww half): every row 0/0 byte-id — this file's assertion.
*
* Probe-OUT, documented NOT pinned (failed at a DIFFERENT site, filed):
* named-tuple global init — cs checker loud-reject, ww accepts (#86)
* plain tagged global — cs silent-wrong, ww loud-reject (#87, not
* alias-family; control row fails)

* 944_alias_idx_family_run — #5 alias arc F2a batch 1 (task #60 +
* the #79 init-store rider): wwstage INDEX / SLICE / FOR-RANGE /
* LITERAL-INIT over an alias-NAMED base type. The tnode-keyed cgen
* walks saw only the N_TNAME leaf — esz fell to the 1-sentinel (8 on
* the init-store side) and the base classified as a POINTER (MOVQ of
* array words + no IMULQ): m8b_idx1/range1 SEGV 139, m8b_slice1
* silent-wrong past prefix-luck (m8c_slice1big exit 2), alias-[4]u32
* literal-init MOVQ stride-8 over a stride-4 slot = saved-BP/RIP
* smash (#79, masked when esz==8). cstage reads everything off the
* chased stamped type (type_chase_named/idx_eff, post-F1), so it is
* the runtime-correct reference; the fix re-keys the ww sites off
* tichase'd stamped tinfos (cgindex/cgassign-N_INDEX/cgslice/
* cgbasecap in cgenexpr.ww, cgforrange + cgarrlitfillbp + bare-let
* classify in cgenstmt.ww, pusharg N_SLICE in cgenutil.ww) and every

/*
* 944_alias_structlit_init_run — #63: let-init from an alias-NAMED
* struct LITERAL. wwstage's cglet N_STRUCTLIT arm resolved the struct
* by a BARE structlookup(c, sname): for an alias `type rep2 = rep`
* only the base `rep` is registered, so the lookup returned nil and
* the field-fill never fired. The nil then split by slot size —
* • <=8B: the small-let scalar default zeroed the slot and DROPPED
* the literal (SILENT wrong: `let r = rep2{id=6}` read 0), and
* • >8B: no fill arm matched -> the cglet "unhandled rhs shape"
* LOUD (task #7/rule-7).
* Same root, two symptoms. The fix routes the arm through
* structlookupchain (the #92/W2 SSoT already used at cgenstmt:1974 /
* :2687), which chases the alias chain to the base struct. cstage
* operates on the resolved Type* via type_chase_named and was always
* correct, so this is ww-only align-UP; cs UNTOUCHED. Oracle: ken
* .ai/ken-63-oracle.md.
*
* The N_IDENT-copy (cgenstmt:2625) and N_CALL-recv (:2511) sibling
* arms are also bare-structlookup but are NOT in scope: the copy
* falls through to a generic path byte-identical with cstage (both
* stages run correct), and the recv is blocked upstream by the
* aggregate-return shape (#272/#277), and the ≤24B return (:1363)
* likewise louds via the scalar-default catch. The >24B sret RETURN
* (:1250) had NO such catch — it was silently wrong (returned an
* uninitialised sret buffer); reviewer-63 routed it through
* structlookupchain in the same commit (see sret_return_alias32).
* The N_IDENT struct-copy (:2625) falls through to a generic path
* both stages run correct (asm divergence is the #81/#65 alias
* field-READ class). See the #63 ledger.
*
* row | shape | want
* -------------------+---------------------------------------+-----
* letinit_typed | type rep2=rep(8B); let r: rep2 = |
* | rep2{id=6}; read r.id (was silent 0) | 6
* letinit_untyped | inferred: let r = rep2{id=6}; r.id | 6
* letlit_alias16 | type row=st(16B); let a: row = |
* | row{a=3,b=4}; read a.a+a.b (was LOUD) | 7
* control_direct | non-alias pt2{...} 16B let-init — the |
* | no-regress control (alias hop is the |
