CARD K1-05  (pre-registered 2026-09-26 02:17:17 -0700)  DIAGNOSTIC ONLY - never a landing shape (house rule "Do not tune declaration
counts, symbol/name counts ... with filler declarations")
Base: k04 (held lab: k01 + uninit play_type + header normalize2d): [size 8096!=8064, sha], frame 0x1274, 36 hunks.
Question: are the remaining held-lab residuals (frame +8 from a different byte/dword packing order; register
  choices eax/edx at 0x8b7, 0x91c; x87 fmul [esi+0x10] position 0x17b5; normalize2d fmul st(1) at 0x1d7d;
  look_secondary movsx) keyed to TU declaration counts (C1 symbol numbering / hash ties) or to source reference
  counts?
Probe: insert K filler "extern long k1_probe_N;" declarations immediately before ai_communication_event (after
  talk_weight's definition, so talk_weight's inputs are untouched), K in {1,2,3,4,8,16,32,64}.
Prediction: frame stays 0x1274 for every K (frame packing is keyed by refs/size, ties aside); some register/x87
  hunks may change with K (hash-keyed ties). If some K gives frame 0x126c the frame residual is a tie-order effect.
Decisive test: frame line and hunk count per K; talk_weight row unchanged.
