minSdk 26 makes AGP default the v1 (JAR) signature off, so the release APK is
v2-only. Some MDM-managed commercial signage (MAXHUB via the Pivot MDM) silently
removes a v2-only app on the next reboot because its boot integrity check expects
a v1 signature — screens that power-cycle nightly lose the app and fall back to
the setup screen.
`enableV1Signing = true` has no effect at minSdk >= 24 (verified: still v2-only).
Instead, finalize assembleRelease with a `resignReleaseV1` task that re-signs via
apksigner with --v1-signing-enabled true and a low --min-sdk-version, emitting v1
alongside v2/v3. Verified: v1+v2+v3 at min-sdk 19, verifies at API 36, and the
re-signed APK installs and runs on a live API 36 emulator.

Each playlist item can carry schedule blocks (active days, start/end
time-of-day, optional start/end dates). An item plays when the screen's
local "now" matches at least one block; an item with no blocks always
plays. #74 covers time-of-day/day-of-week windows including overnight
wrap; #75 covers inclusive date ranges (auto-expiry). Evaluation is
on-device, so dayparting and expiry work offline.
- Shared evaluator contract: shared/schedule-vectors.json (39 vectors —
DST US+AU, overnight-wrap anchoring, timezone correctness, date
boundaries). Canonical JS evaluator in server/lib/schedule-eval.js;
Kotlin and Tizen ports kept in lockstep by drift guards (Tizen byte-diff
test, Kotlin JUnit reads the shared JSON, new android-test CI job).
- All three players (web, Android, Tizen) filter by schedule against their
own clock, idle with a "Nothing scheduled" message + 30s re-check when
everything is filtered, and fail open on any evaluator error.
- Editor: per-item schedule modal + row badge in the playlist editor;
client validation mirrors the server; editing marks the playlist draft.
- Part B (behaviour change): device/group schedule overrides now evaluate
in each device's effective timezone instead of server-local time.
- Device detail shows the reported timezone + a clock-skew warning.
- i18n for en/es/fr/de/pt across all new strings (namespaced itemsched.*
to avoid colliding with the device-schedule calendar's schedule.*).
- CHANGELOG documents the feature, the Part B change, the fail-open
guarantee, and the scheduled-single-video re-render tradeoff.
