bootstrap: QUOTA_LEFT_HOURS 24.9 from the 11:10Z live read -- session 1 launch card

phase4_bootstrap: REV must be at or after the launcher it sha-pins -- point at c237b478

phase4_bootstrap: repin to the D-018 launcher at c237b478

phase4_bootstrap: E-044 repin (rank-0 stop assertions; memory gate moved onto the training-only leg)

phase4_bootstrap: repin to b6210a29 (per-rank post-train marks + readable probe failures)

phase4_bootstrap: E-042 repin + rehearsal of the launcher's real argv and the prune guard

phase4_bootstrap: pins at a813e5c7 + bounded-readback rehearsal stage / tee-prefix fix

pin 7570b7b2: forced-stop legs skip the collective validation pass; probe expectations split leg1 (skip by design) from leg2 (must run it)

pin 850729d3 (review round 3)

pin 1dd45f80 (E-037 launcher fix)

kernels: pin 91fb319f (argparse help fix)
