libavr's calibrate() now bounds its measurement loop, starts the pulse on an observed edge, and re-arms a rejected pulse on the remaining budget instead of one-strike booting the application. The autobaud images pay +16..20 B — every slot still fits, the worst now the 1284s' 502 of 512 — and the stock images are byte-identical, kept so by fitting the loader's flag set per backend: -fno-ivopts stays on the fixed-baud bodies it shrinks and comes off the autobaud body, where it duplicated the calibration countdown into a 9-cycle loop against the contracted seven. One deployed constant moved and its gate caught it: the calibrate wait's budget poll re-laid from ten cycles to nine (the exit branches land where block layout puts them), so pureboot.window.autobaud measured -10 % until AUTOBAUD_POLL_CYCLES and the README's derived seconds were re-measured — the default autobaud window is 36 M cycles, 4.5 s at 8 MHz. Full gate green on all 37 chips; the README's autobaud column carries each chip's rebuilt worst configuration, machine-checked against the built trees.
