Three different Flutter versions were in play and none was the bench:
build.yml channel: stable (floating, resolving to 3.44.6)
flutter_dart.yml channel: stable (floating)
deploy.yml pinned 3.41.2, with a comment claiming it matched
local development, which had not been true for months
bench 3.44.1 / Dart 3.12.1
A floating toolchain is tolerable for a compile check and not tolerable
once CI produces signed release artifacts (#330), so this lands first.
Pinned all 8 flutter-action usages to 3.44.1, matching the bench exactly,
so "works locally" and "works in CI" mean the same thing. Verified against
Flutter's release index that 3.44.1 is a published stable release
(2026-06-01, Dart 3.12.1) rather than assuming a locally-installed
version was publicly fetchable.
Corrected deploy.yml's misleading local-parity comment rather than
leaving it to mislead the next reader.
Note: CI's green history is on 3.44.6 or later, so pinning DOWN may
surface a break the newer toolchain masked. That is the intent. If it
breaks, fix the break or move the bench up deliberately; do not re-float
the pin.
GIPHY_API_KEY as a CI secret was the third item of Phase 3 in #321. It
is deliberately NOT included here, is not dropped, and is flagged on
#331 for the owner's decision, since it is a credential only they can
create.
Part of epic #312, plan #321 (Phase 3).
