Subject: paper v2.30: fix layer-0 cosine numbers + add per-seed appendix M
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Found a numerical error in §4 ¶3: the layer-0 vanilla DFA cosines were
listed as +0.42, +0.45, +0.39 across seeds 42/123/456 but the actual
re-measurement on the saved early-epoch checkpoints gives +0.421, +0.436,
+0.418 (the s456 value was off by 0.03). The deep-mean numbers in
Table 2 (-0.008 ± 0.013) were already correct.

Changes:
- §4 ¶3: layer-0 trio updated to +0.42, +0.44, +0.42 across seeds and
  cite now points to a new per-seed appendix.
- New Appendix M (Layer-0 Dominance): 6-row table of per-seed per-layer
  cosines on vanilla DFA early checkpoints (3 seeds × ep 1, 2), with
  per-layer ||g||. Documents the layer-0 dominance pattern that drives
  the headline aggregate Γ on these checkpoints.
- results/vanilla_dfa_early_ckpts/per_layer_cos_3seed.json: machine-
  readable dump of all 6 measurements for future audit.
- §7 compressed (~30 words trimmed across the closing paragraph) and
  Figure 3 width 0.92 → 0.82 to keep main content at exactly 9 pages
  after the appendix addition.

Verified: 9 pages main + refs on p10, 18 total, 0 overfull boxes.
