Four cuts, none touching what the loader can do. The entry stub stops re-doing the reset logic's own SP write where the datasheet guarantees RAMEND (stack::hardware — the classic megas keep theirs). The autobaud unit moves into GPIOR2:GPIOR1 wherever the chip has the pair: one-word accesses, no RAM object, and the host's measured-clock peek follows it by version and geometry. 'J' rides the unified decode, carrying a selector it ignores so its address is the same two reads as every other command — the tool sends the bare form to older residents. run_app stops insisting on a body of its own. The fleet lands at 358–410 B stock and 438–474 B autobaud; the tightest image in the space — the 1284s' autobaud on a USART's own pins with the OSCCAL trim — drops from 510 to 484 of its 512. Every chip's suite is green on the wire that changed, and the README's table is machine-checked against the built images. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
