v0.1.0-alpha.17 — Brick: NFC tap-to-block app blocking (Foqos-style), 3s vault hold, fixes

[codebooo]

1. Brick — new module

Foqos-style tap-to-block, built on the only mechanism Android gives a sideloaded app (Family Link's supervision APIs are restricted to Google's own package): an accessibility service that watches which app comes to the front and replaces blocked ones with a full-screen wall.

• Modes (profiles) — name, blocked app list (installed-app picker w/ search + system-app toggle), optional per-app daily allowances (15/30/60 min or hard block).
• Activators — NFC tag, time window, or manual. Independent on/off triggers: e.g. tag-on, time-off.
• NFC — pair any tag/card in the editor via reader mode; tapping it later opens a no-history activity that flips the matching mode and closes. Tag id is the tag's hardware UID, so no writing to the tag is needed. Foil for the intended flow: keep the tag far away, and it's the only key.
• Strict mode — refuses the in-app end button, so only the real condition unlocks.
• Block wall — full-screen "Blocked" screen with the unlock hint; Back is swallowed and only leads Home. Blocked-attempt counter per session.
• Allowances — the service accounts foreground seconds per app per day itself (no Usage Access needed) and walls the app once the allowance is spent.
• Time windows — AlarmManager (setAndAllowWhileIdle) arms the next start/end edge per profile; re-armed on every refresh, so reboots are covered when the service reconnects.

Verification: the rules that must never be wrong were extracted into a pure BrickPolicy and covered by 12 JVM unit tests, all passing — blocked vs allowed vs allowance-spent, zero-minute allowance is a hard block, allowances don't leak between apps, LifeOS itself is never blockable (or you couldn't unlock), NFC-only modes reject manual/time exits, strict modes reject everything but their condition, force-stop still works if a running profile is deleted. Debug + minified release builds pass.

Honest caveat: a determined user can still disable the accessibility service in system settings — no non-privileged Android app can prevent that. Everything short of that is enforced.

2. Vault reveal

Hold on the Home "LifeOS" title reduced from 5s to 3s.

3. General fixes

• Brick state reloads at app start, so a live mode and its time alarms survive reboots.
• Screen Time sync no longer re-queries all 45 days on every refresh — stored days are skipped (today/yesterday still refresh), which removes a multi-second stall on opening the module.
• Settings gains an "App blocking (Brick)" accessibility shortcut next to the other system grants.

Room v14 (4 Brick tables, auto-migration). versionCode 17.
