docs(alarms): unify and enhance alarm directive documentation stack

Create unified alarm documentation system with strict role separation: - Doc A: Platform capability reference (canonical OS facts) - Doc B: Plugin behavior exploration (executable test harness) - Doc C: Plugin requirements (guarantees, JS/TS contract, traceability) Changes: - Add canonical rule to Doc A preventing platform fact duplication - Convert Doc B to pure executable test spec with scenario tables - Complete Doc C with guarantees matrix, JS/TS API contract, recovery contract, unsupported behaviors, and traceability matrix - Remove implementation details from unified directive - Add compliance milestone tracking and iOS parity gates - Add deprecation banners to legacy platform docs All documents now enforce strict role separation with cross-references to prevent duplication and ensure single source of truth.

+# Platform Capability Reference: Android & iOS Alarm/Notification Behavior
+
+**Author**: Matthew Raymer  
+**Date**: November 2025  
+**Status**: Platform Reference - Stable  
+**Version**: 1.1.0  
+**Last Synced With Plugin Version**: v1.1.0
+
+## Purpose
+
+This document provides **pure OS-level facts** about alarm and notification capabilities on Android and iOS. It contains **no plugin-specific logic**—only platform mechanics that affect plugin design.
+
+**This is a reference document** to be consulted when designing plugin behavior, not an implementation guide.
+
+**⚠️ CANONICAL RULE**: No other document may contain OS-level behavior. All platform facts **MUST** reference this file. If platform behavior is described elsewhere, it **MUST** be moved here and replaced with a reference.
+
+**⚠️ DEPRECATED**: The following documents are superseded by this reference:
+- `platform-capability-reference.md` - Merged into this document
+- `android-alarm-persistence-directive.md` - Merged into this document
+
+**See**: [Unified Alarm Directive](./000-UNIFIED-ALARM-DIRECTIVE.md) for document structure.
+
+---
+
+## 1. Core Principles
+
+### Android
+
+Android does **not** guarantee persistence of alarms across process death, swipes, or reboot.
+
+It is the app's responsibility to **persist alarm definitions** and **re-schedule them** under allowed system conditions.
+
+### iOS
+
+iOS **does** persist scheduled local notifications across app termination and device reboot, but:
+
+* App code does **not** run when notifications fire (unless user interacts)
+* Background execution is severely limited
+* Apps must persist their own state if they need to track or recover missed notifications
+
+---

+| **App silently killed by OS**           | ✅ Yes                                   | AlarmManager still holds scheduled alarms                            | None (OS handles)                                     | OS-guaranteed |
+| **Device Reboot**                       | ❌ No (auto) / ✅ Yes (if app reschedules) | All alarms wiped on reboot                                           | Apps may reschedule from persistent storage on boot       | Plugin-required |
+| **Doze Mode**                           | ⚠️ Only "exact" alarms                  | Inexact alarms deferred; exact alarms allowed                       | Apps must use `setExactAndAllowWhileIdle`                  | Plugin-required |
+| **Force Stop**                          | ❌ Never                                 | Android blocks all callbacks + receivers until next user launch     | Cannot bypass; apps may detect on app restart             | Forbidden     |
+| **User reopens app**                    | ✅ Apps may reschedule & recover          | App process restarted                                                | Apps may detect missed alarms and reschedule future ones   | Plugin-required |
+| **PendingIntent from user interaction** | ✅ If triggered by user                  | User action unlocks the app                                          | None (OS handles)                                     | OS-guaranteed |
+
+### 2.1 Android Allowed Behaviors
+
+#### 2.1.1 Alarms survive UI kills (swipe from recents)
+
+**OS-guaranteed**: `AlarmManager.setExactAndAllowWhileIdle(...)` alarms **will fire** even after:
+* App is swiped away
+* App process is killed by the OS
+
+The OS recreates your app's process to deliver the `PendingIntent`.
+
+**Required API**: `setExactAndAllowWhileIdle()` or `setAlarmClock()`
+
+#### 2.1.2 Alarms can be preserved across device reboot
+
+**Plugin-required**: Android wipes all alarms on reboot, but **apps may recreate them**.
+
+**OS Behavior**: All alarms are cleared on device reboot. No alarms persist automatically.
+
+**App Capability**: Apps may recreate alarms after reboot by:
+1. Persisting alarm definitions in durable storage (Room DB, SharedPreferences, etc.)
+2. Registering a `BOOT_COMPLETED` / `LOCKED_BOOT_COMPLETED` broadcast receiver
+3. Rescheduling alarms from storage after boot completes
+
+**Required Permission**: `RECEIVE_BOOT_COMPLETED`
+
+**OS Condition**: User must have launched the app at least once before reboot for boot receiver to execute
+
+#### 2.1.3 Alarms can fire full-screen notifications and wake the device
+
+**OS-guaranteed**: **Required API**: `setFullScreenIntent(...)`, use an IMPORTANCE_HIGH channel with `CATEGORY_ALARM`
+
+This allows Clock-app–style alarms even when the app is not foregrounded.
+
+#### 2.1.4 Alarms can be restored after app restart
+
+**Plugin-required**: If the user re-opens the app (direct user action), apps may:
+* Access persistent storage (database, files, etc.)
+* Query alarm definitions
+* Reschedule alarms using AlarmManager
+* Reconstruct WorkManager/JobScheduler tasks that were cleared
+
+**OS Behavior**: When user opens app, app code can execute. AlarmManager and WorkManager APIs are available for rescheduling.
+
+**Note**: This is an app capability, not OS-guaranteed behavior. Apps must implement this logic.
+
+### 2.2 Android Forbidden Behaviors
+
+#### 2.2.1 You cannot survive "Force Stop"
+
+**Forbidden**: **Settings → Apps → YourApp → Force Stop** triggers:
+* Removal of all alarms
+* Removal of WorkManager tasks
+* Blocking of all broadcast receivers (including BOOT_COMPLETED)
+* Blocking of all JobScheduler jobs
+* Blocking of AlarmManager callbacks
+* Your app will NOT run until the user manually launches it again
+
+**Directive**: Accept that FORCE STOP is a hard kill. No scheduling, alarms, jobs, or receivers may execute afterward.
+
+#### 2.2.2 You cannot auto-resume after "Force Stop"
+
+**Forbidden**: You may only resume tasks when:
+* The user opens your app
+* The user taps a notification belonging to your app
+* The user interacts with a widget/deep link
+* Another app explicitly targets your component
+
+**OS Behavior**: Apps may only resume tasks when user opens app, taps notification, interacts with widget/deep link, or another app explicitly targets the component.
+
+#### 2.2.3 Alarms cannot be preserved solely in RAM
+
+**Forbidden**: Android can kill your app's RAM state at any time.
+
+**OS Behavior**: All alarm data must be persisted in durable storage. RAM-only storage is not reliable.
+
+#### 2.2.4 You cannot bypass Doze or battery optimization restrictions without permission
+
+**Conditional**: Doze may defer inexact alarms; exact alarms with `setExactAndAllowWhileIdle` are allowed.
+
+**Required Permission**: `SCHEDULE_EXACT_ALARM` on Android 12+ (API 31+)

+| **Device Reboot**                       | ✅ Yes (for calendar/time triggers) | iOS persists scheduled local notifications across reboot             | None for notifications; must persist own state if needed | OS-guaranteed |
+| **App Force Quit (swipe away)**          | ✅ Yes                   | UNUserNotificationCenter persists and fires notifications             | None (OS handles)                                     | OS-guaranteed |

+
+### 3.1 iOS Allowed Behaviors
+
+#### 3.1.1 Notifications survive app termination
+
+**OS-guaranteed**: `UNUserNotificationCenter` scheduled notifications **will fire** even after:
+* App is swiped away from app switcher
+* App is terminated by system
+* Device reboots (for calendar/time-based triggers)
+
+**Required API**: `UNUserNotificationCenter.add()` with `UNCalendarNotificationTrigger` or `UNTimeIntervalNotificationTrigger`
+
+#### 3.1.2 Notifications persist across device reboot
+
+**OS-guaranteed**: iOS **automatically** persists scheduled local notifications across reboot.
+
+**No app code required** for basic notification persistence.
+
+**Limitation**: Only calendar and time-based triggers persist. Location-based triggers do not.
+
+#### 3.1.3 Background tasks for prefetching
+
+**Conditional**: **Required API**: `BGTaskScheduler` with `BGAppRefreshTaskRequest`
+
+**Limitations**:
+* Minimum interval between tasks (system-controlled, typically hours)
+* System decides when to execute (not guaranteed)
+* Cannot rely on background execution for alarm recovery
+* Must schedule next task immediately after current one completes
+
+### 3.2 iOS Forbidden Behaviors
+
+#### 3.2.1 App code does not run when notification fires
+
+**Forbidden**: When a scheduled notification fires:
+* Notification is displayed to user
+* **No app code executes** unless user taps the notification
+* Cannot run arbitrary code at notification time
+
+**Workaround**: Use notification actions or handle missed notifications on next app launch.
+
+#### 3.2.2 No repeating background execution
+
+**Forbidden**: iOS does not provide repeating background execution APIs except:
+* `BGTaskScheduler` (system-controlled, not guaranteed)
+* Background fetch (deprecated, unreliable)
+
+**OS Behavior**: Apps cannot rely on background execution to reconstruct alarms. Apps must persist state and recover on app launch.
+
+#### 3.2.3 No arbitrary code on notification trigger
+
+**Forbidden**: Unlike Android's `PendingIntent` which can execute code, iOS notifications only:
+* Display to user
+* Launch app if user taps
+* Execute notification action handlers (if configured)
+
+**OS Behavior**: All recovery logic must run on app launch, not at notification time.
+
+#### 3.2.4 Background execution limits
+
+**Forbidden**: **BGTaskScheduler Limitations**:
+* Minimum intervals between tasks (system-controlled)
+* System may defer or skip tasks
+* Tasks have time budgets (typically 30 seconds)
+* Cannot guarantee execution timing
+
+**Directive**: Use BGTaskScheduler for prefetching only, not for critical scheduling.

+    ├─ Not granted → Must request permission
+    │   ├─ User grants → Can schedule exact alarms
+    │   └─ User denies → Cannot schedule exact alarms (use inexact or show error)
+    └─ Revoked → Cannot schedule exact alarms (user must re-enable in Settings)
+```
+
+**Label**: Conditional (requires user permission on Android 12+)
+

+
+## 9. Label Definitions
+
+**Required Labels** (every platform behavior MUST be tagged):
+
+| Label | Definition | Usage |
+| ----- | ---------- | ----- |
+| **OS-Guaranteed** | The operating system provides this behavior automatically. No plugin code required. | Use when OS handles behavior without app intervention |
+| **OS-Permitted but not guaranteed** | The OS allows this behavior, but timing/execution is not guaranteed. Plugin may need fallbacks. | Use for background execution, system-controlled timing |
+| **Forbidden** | This behavior is not possible on this platform. Plugin must not attempt it. | Use for hard OS limitations (e.g., Force Stop bypass) |
+| **Undefined / OEM-variant** | Behavior varies by device manufacturer or OS version. Not universal. | Use when behavior differs across OEMs or OS versions |
+
+**Legacy Labels** (maintained for backward compatibility):
+- **Plugin-required**: The plugin must implement this behavior. The OS does not provide it automatically.
+- **Conditional**: This behavior is possible but requires specific conditions (permissions, APIs, etc.).
+
+---
+
+## 10. OEM Variation Policy
+
+**Android is not monolithic** — behavior may vary by OEM (Samsung, Xiaomi, Huawei, etc.).
+
+**Policy**:
+* **Do not document** until reproduced in testing
+* **Mark as "Observed-variant (not universal)"** if behavior differs from AOSP
+* **Test on multiple devices** before claiming universal behavior
+* **Document OEM-specific workarounds** in Doc C (Requirements), not Doc A (Platform Facts)
+
+**Example**:
+* ❌ **Wrong**: "All Android devices wipe alarms on reboot"
+* ✅ **Correct**: "AOSP Android wipes alarms on reboot. Observed on: Samsung, Pixel, OnePlus. Not tested on: Xiaomi, Huawei."
+
+---
+
+## 11. Citation Rule
+
+**Platform facts must come from authoritative sources**:
+
+**Allowed Sources**:
+1. **AOSP source code** - Direct inspection of Android Open Source Project
+2. **Official Android/iOS documentation** - developer.android.com, developer.apple.com
+3. **Reproducible test results** (Doc B) - Empirical evidence from testing
+
+**Prohibited Sources**:
+* Stack Overflow answers (unless verified)
+* Blog posts (unless citing official docs)
+* Assumptions or "common knowledge"
+* Unverified OEM-specific claims
+
+**Citation Format**:
+* For AOSP: `[AOSP: AlarmManager.java:123]`
+* For official docs: `[Android Docs: AlarmManager]`
+* For test results: `[Doc B: Test 4 - Device Reboot]`
+
+**If source is unclear**: Mark as "Unverified" or "Needs citation" until verified.

+# Plugin Behavior Exploration: Alarm/Schedule/Notification Testing
+
+**Author**: Matthew Raymer  
+**Date**: November 2025  
+**Status**: Active Exploration Template  
+**Version**: 1.1.0  
+**Last Synced With Plugin Version**: v1.1.0
+
+## Purpose
+
+This document provides an **executable test harness** for exploring and documenting the current plugin's alarm/schedule/notification behavior on Android and iOS.
+
+**This is a test specification document** - it contains only test scenarios, expected results, and actual results. It does NOT contain platform explanations or requirements.
+
+**Use this document to**:
+1. Execute test scenarios
+2. Document actual vs expected results
+3. Identify gaps between current behavior and requirements
+4. Generate findings for the Plugin Requirements document
+
+**⚠️ RULE**: This document contains NO platform explanations. All expected OS behavior must reference [Doc A](./01-platform-capability-reference.md). All expected plugin behavior must reference [Doc C](./03-plugin-requirements.md).
+
+**Reference**: 
+- [Platform Capability Reference](./01-platform-capability-reference.md) - OS-level facts (Doc A)
+- [Plugin Requirements](./03-plugin-requirements.md) - Plugin guarantees and requirements (Doc C)
+
+---
+
+## 0. Reproducibility Protocol
+
+**Each scenario MUST define**:
+
+1. **Device model & OS version**: e.g., "Pixel 7, Android 14", "iPhone 15, iOS 17"
+2. **App build hash**: Git commit hash or build number
+3. **Preconditions**: State before test (alarms scheduled, app state, etc.)
+4. **Steps**: Exact sequence of actions
+5. **Expected vs Actual**: Clear comparison of expected vs observed behavior
+
+**Reproducibility Requirements**:
+* Test must be repeatable by another engineer
+* All steps must be executable without special setup
+* Results must be verifiable (logs, UI state, database state)
+* Timing-sensitive tests must specify wait times
+
+**Failure Documentation**:
+* Capture logs immediately
+* Screenshot UI state if relevant
+* Record exact error messages
+* Note any non-deterministic behavior

+
+## 5. Findings & Gaps
+
+### 4.1 Android Gaps
+
+| Gap | Severity | Description | Recommendation |
+| --- | -------- | ----------- | -------------- |
+| Boot recovery | ☐ Critical/Major/Minor/Expected | Does plugin reschedule on boot? | Implement if missing |
+| Missed alarm detection | ☐ Critical/Major/Minor/Expected | Does plugin detect missed alarms? | Implement if missing |
+| Force stop recovery | ☐ Critical/Major/Minor/Expected | Does plugin recover after force stop? | Implement if missing |
+| Persistence completeness | ☐ Critical/Major/Minor/Expected | Are all required fields persisted? | Verify and add if missing |
+
+**Severity Classification**:
+- **Critical**: Breaks plugin guarantee (see [Doc C §1.1](./03-plugin-requirements.md#11-guarantees-by-platform))
+- **Major**: Unexpected but recoverable (plugin works but behavior differs from expected)
+- **Minor**: Non-blocking deviation (cosmetic or edge case)
+- **Expected**: Platform limitation (documented in [Doc A](./01-platform-capability-reference.md))
+
+### 4.2 iOS Gaps
+
+| Gap | Severity | Description | Recommendation |
+| --- | -------- | ----------- | -------------- |
+| Missed notification detection | ☐ Critical/Major/Minor/Expected | Does plugin detect missed notifications? | Implement if missing |
+| Plugin-side persistence | ☐ Critical/Major/Minor/Expected | Does plugin persist state separately? | Consider if needed |
+| Background task reliability | ☐ Critical/Major/Minor/Expected | Can plugin rely on BGTaskScheduler? | Document limitations |
+
+**Severity Classification**: Same as Android (see above).
