The App Submission API stopped resolving apps by package name and now
returns 400 "No app found with the entered Inputs"; it requires the
amzn1.devportal.mobileapp app id from the console URL. Read the id from
AMAZON_APPSTORE_APP_ID, validate it in preflight, and keep the package
name for console-facing messages.
The scripts reorganization moved upload_symbols.dart from scripts/ into
scripts/release/ but kept the single-.parent root resolution, so the
script searched scripts/build and scripts/debug-info and every CI symbol
upload failed with "no symbols found". The sibling checks scripts were
updated to .parent.parent in the same move; match them.
One command releases to Play, Amazon, App Store Connect (iOS + tvOS), the GitHub build farm, Microsoft Store, and the GitHub release + cask, with checkpointed resume. Replaces the fastlane release flow; first used for 2.14.0.
scripts/ had ~80 flat files. Entry points (ci_*.sh, codegen.sh, run_tests.sh, format_native.sh, setup_hooks.sh, upload-symbols.*) and the shared pubspec_version.py stay at the root; checkers, generators, maestro tooling and release tooling move into subdirectories with their tests. Updated every reference: workflow steps, guard-test glob, Docker COPY paths and .dockerignore whitelist, website audit path, dart test imports, and regenerated the five outputs whose headers embed generator paths.
