Drew T 2f7e06564b feat(phase-30 S50): the stale seed symbol — A-prop's 57% was ours, not the lane's (§171)
- REFUTES §170's open hypothesis (batched cards concentrate members into one TU ⇒ §169
  collision): 5-draft groups banked 5/5; 11 of 35 unbanked drafts were already one-per-TU;
  and the two "concentrated" groups banked 12/12 and 10/10 once the real defect was fixed.
- The cause: a per-location data symbol carried out of the seed body unrebased. match_one
  compares instruction ENCODINGS and is blind to a relocation's target NAME, so it scores
  MATCH standalone and dies at link in the host TU. 24 of 24 concentrated failures, all 1:1
  rewritable at one constant vram delta (0x4128).
- tools/aprop_symfix.py: audit + --fix, emits a gate_lane-shaped slate; deterministic and
  build-free, so it runs BEFORE the gate. The R34 second oracle for the class match_one
  cannot see.
- family_cousins.py --aprop-cards: members now carry sym_map, the explicit {seed -> member}
  renames, read from the seed's C BODY (a matched seed has no .s of its own) vs the member's
  .s. Two case-mismatch defects fixed while wiring it (sig lowercase vs splat uppercase).
- 23/24 banked. Stubs 12,468 -> 12,445. Fleet 95.2% instr / 89.9% distinct / 96.57% fn.
  R22 clean rebuild: check-all 213 passed, 0 failed of 213. dedup 2,043/0.
- A-prop's true conversion is 87% (79/91); the 320 batched members are unblocked.
- Cookbook §171 + §170 struck in place; SETUP row; decision-log (R31).
