+title: Documentation, References, and Model Agent Use
+version: 1.1
+alwaysApply: true
+scope: code, project-plans
+---
+
+# Directive on Documentation, References, and Model Agent Use in Code and Project Plans
+
+To ensure clarity, efficiency, and high-value documentation within code and project plans—and to leverage **model agents** (AI- or automation-based assistants) effectively—contributors must follow these rules:
+
+---
+
+## 1. Documentation and References Must Add Clear Value
+
+- Only include documentation, comments, or reference links when they provide _new, meaningful information_ that assists understanding or decision-making.  
+- Avoid duplicating content already obvious in the codebase, version history, or linked project documents.
+
+---
+
+## 2. Eliminate Redundant or Noisy References
+
+- Remove references that serve no purpose beyond filling space.  
+- Model agents may automatically flag and suggest removal of trivial references (e.g., links to unchanged boilerplate or self-evident context).
+
+---
+
+## 3. Explicit Role of Model Agents
+
+Model agents are **active participants** in documentation quality control. Their tasks include:  
+
+- **Relevance Evaluation**: Automatically analyze references for their substantive contribution before inclusion.  
+- **Redundancy Detection**: Flag duplicate or trivial references across commits, files, or tasks.  
+- **Context Linking**: Suggest appropriate higher-level docs (designs, ADRs, meeting notes) when a code change touches multi-stage or cross-team items.  
+- **Placement Optimization**: Recommend centralization of references (e.g., in plan overviews, ADRs, or merge commit messages) rather than scattered low-value inline references.  
+- **Consistency Monitoring**: Ensure references align with team standards (e.g., ADR template, architecture repo, or external policy documents).  
+
+Contributors must treat agent recommendations as **first-pass reviews** but remain accountable for final human judgment.
+
+---
+
+## 4. Contextual References for Complex Items
+
+- Use **centralized references** for multi-stage features (e.g., architectural docs, research threads).  
+- Keep inline code comments light; push broader context into centralized documents.  
+- Model agents may auto-summarize complex chains of discussion and attach them as a single reference point.
+
+---
+
+## 5. Centralization of Broader Context
+
+- Store overarching context (design docs, proposals, workflows) in accessible, well-indexed places.  
+- Model agents should assist by **generating reference maps** that track where docs are cited across the codebase.
+
+---
+
+## 6. Focused Documentation
+
+- Documentation should explain **why** and **how** decisions are made, not just what was changed.  
+- Model agents can auto-generate first-pass explanations from commit metadata, diffs, and linked issues—but humans must refine them for accuracy and intent.
+
+---
+
+## 7. Review and Accountability
+
+- Reviewers and team leads must reject submissions containing unnecessary or low-quality documentation.  
+- Model agent outputs are aids, not replacements—contributors remain responsible for **final clarity and relevance**.
+
+---
+
+## 8. Continuous Improvement and Agent Feedback Loops
+
+- Encourage iterative development of model agents so their evaluations become more precise over time.  
+- Contributions should include **feedback on agent suggestions** (e.g., accepted, rejected, or corrected) to train better future outputs.  
+- Agents should log patterns of “rejected” suggestions for refinement.  
+
+---
+
+## 9. Workflow Overview (Mermaid Diagram)
+
+```mermaid
+flowchart TD
+    A[Contributor] -->|Writes Code & Draft Docs| B[Model Agent]
+    B -->|Evaluates References| C{Relevant?}
+    C -->|Yes| D[Suggest Placement & Context Links]
+    C -->|No| E[Flag Redundancy / Noise]
+    D --> F[Contributor Refines Docs]
+    E --> F
+    F --> G[Reviewer]
+    G -->|Approves / Requests Revisions| H[Final Documentation]
+    G -->|Feedback on Agent Suggestions| B
+```
+
+---
+
+✅ **Outcome:** By integrating disciplined contributor standards with **model agent augmentation**, the team achieves documentation that is consistently _relevant, concise, centralized, and decision-focused_. AI ensures coverage and noise reduction, while humans ensure precision and judgment.

+# Glossary
+
+**📝 SANITY CHECK IMPROVEMENTS APPLIED:** This document has been updated to accurately reflect current implementation status vs. planned features.
+
+**T (slot time)** — The local wall-clock time a notification should fire (e.g., 08:00). *See Notification System → Scheduling & T–lead.*
+
+**T–lead** — The moment **`prefetchLeadMinutes`** before **T** when the system *attempts* a **single** background prefetch. T–lead **controls prefetch attempts, not arming**; locals are pre-armed earlier to guarantee closed-app delivery. *See Notification System → Scheduling & T–lead and Roadmap Phase 2.1.*
+
+**Lead window** — The interval from **T–lead** up to **T** during which we **try once** to refresh content. It does **not** control arming; we pre-arm earlier. *See Notification System → Scheduling & T–lead.*
+
+**Rolling window** — Always keep **today's remaining** (and tomorrow if iOS pending caps allow) locals **armed** so the OS can deliver while the app is closed. *See Notification System → Scheduling & T–lead and Roadmap Phase 1.3.*
+
+**TTL (time-to-live)** — Maximum allowed payload age **at fire time**. If `T − fetchedAt > ttlSeconds`, we **skip** arming for that T. *See Notification System → Policies and Roadmap Phase 1.2.*
+
+**Shared DB (planned)** — The app and plugin will open the **same SQLite file**; the app owns schema/migrations, the plugin performs short writes with WAL. *Currently using SharedPreferences/UserDefaults.* *See Notification System → Storage and Roadmap Phase 1.1.*
+
+**WAL (Write-Ahead Logging)** — SQLite journaling mode that permits concurrent reads during writes; recommended for foreground-read + background-write. *See Notification System → Storage and Roadmap Phase 1.1.*
+
+**`PRAGMA user_version`** — An integer the app increments on each migration; the plugin **checks** (does not migrate) to ensure compatibility. *See Notification System → Storage and Roadmap Phase 1.1.*
+
+**Exact alarm (Android)** — Minute-precise alarm via `AlarmManager.setExactAndAllowWhileIdle`, subject to policy and permission. *See Notification System → Policies and Roadmap Phase 2.2.*
+
+**Windowed alarm (Android)** — Batched/inexact alarm via `setWindow(start,len)`; we target **±10 minutes** when exact alarms are unavailable. *See Notification System → Policies and Roadmap Phase 2.2.*
+
+**Delivery-time mutation (iOS)** — Not available for **local** notifications. Notification Service Extensions mutate **remote** pushes only; locals must be rendered before scheduling. *See Notification System → Policies.*
+
+**Start-on-Login** — Electron feature that automatically launches the application when the user logs into their system, enabling background notification scheduling and delivery after system reboot. *See Roadmap Phase 2.3.*
+
+**Tiered Storage (current)** — Current implementation uses SharedPreferences (Android) / UserDefaults (iOS) for quick access, in-memory cache for structured data, and file system for large assets. *See Notification System → Storage and Roadmap Phase 1.1.*
+
+**No delivery-time network:** Local notifications display **pre-rendered content only**; never fetch at delivery. *See Notification System → Policies.*

+# Daily Notification Plugin - Implementation Roadmap
+
+**📝 SANITY CHECK IMPROVEMENTS APPLIED:** This document has been updated to clarify current implementation status and distinguish between existing infrastructure and planned T–lead logic.
+
+**Status:** Ready for implementation  
+**Date:** 2025-01-27  
+**Author:** Matthew Raymer  
+**Assessment Date:** 2025-01-27
+
+---
+
+## Executive Summary
+
+This document outlines the implementation roadmap to bring the current Daily Notification Plugin (65% complete) to full compliance with the Native-First Notification System specification. The implementation is organized into three phases, with Phase 1 containing critical infrastructure components required for core functionality.
+
+### Current State Assessment
+- **Overall Completion:** 65% of specification requirements
+- **Critical Gaps:** SQLite database sharing, TTL-at-fire enforcement, rolling window safety
+- **Current Storage:** SharedPreferences (Android) / UserDefaults (iOS) + in-memory cache
+- **Background Infrastructure:** Basic WorkManager (Android) exists, but lacks T–lead logic
+- **Critical Path:** Data persistence → Freshness enforcement → Platform completion
+
+---
+
+## Current Implementation Status Clarification
+
+### Background Fetch Infrastructure
+**Current State:** Basic infrastructure exists but lacks T–lead logic
+- **Android:** `DailyNotificationFetchWorker.java` (WorkManager) exists
+- **Android:** `DailyNotificationFetcher.java` with scheduling logic exists
+- **Missing:** T–lead calculation, TTL enforcement, ETag support
+- **Status:** Infrastructure ready, T–lead logic needs implementation
+
+### iOS Implementation Status
+**Current State:** Basic plugin structure with power management
+- **Implemented:** Plugin skeleton, power management, UserDefaults storage
+- **Missing:** BGTaskScheduler, background tasks, T–lead prefetch
+- **Status:** Foundation exists, background execution needs implementation
+
+---
+
+**Gate:** No further freshness or scheduling work merges to main until **shared SQLite** (see Glossary → Shared DB) is in place and reading/writing under **WAL** (see Glossary → WAL), with UI hot-read verified.
+
+**Dependencies:** None
+
+### 1.1 SQLite Database Sharing Implementation
+
+**Priority:** CRITICAL
+
+#### Requirements
+- Migrate from SharedPreferences/UserDefaults to shared SQLite database (see Glossary → Shared DB)
+- WAL mode configuration for concurrent access (see Glossary → WAL)
+- Schema version checking and compatibility validation (see Glossary → PRAGMA user_version)
+- Required tables: `notif_contents`, `notif_deliveries`, `notif_config`
+- **Migration Strategy:** Gradual migration from current tiered storage (see Glossary → Tiered Storage)
+
+#### Implementation Tasks
+- [ ] **Migration from Current Storage**
+  - Create migration utilities from SharedPreferences to SQLite
+  - Implement data migration from UserDefaults to SQLite (iOS)
+  - Add backward compatibility during transition
+  - Preserve existing notification data during migration
+
+- [ ] **SQLite Setup (Android)**
+  - Create `DailyNotificationDatabase.java` with WAL mode (see Glossary → WAL)
+  - Implement schema version checking (`PRAGMA user_version`) (see Glossary → PRAGMA user_version)
+  - Add database connection management with proper error handling
+
+- [ ] **Database Configuration**
+  - Add `dbPath: string` to `ConfigureOptions` interface
+  - Implement database path resolution (absolute vs platform alias)
+  - Add `storage: 'shared'` configuration option
+  - Extend existing `NotificationOptions` with database settings
+
+- [ ] **Database Schema**
+  ```sql
+  -- notif_contents: keep history, newest-first reads
+  CREATE TABLE IF NOT EXISTS notif_contents(
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    slot_id TEXT NOT NULL,
+    payload_json TEXT NOT NULL,
+    fetched_at INTEGER NOT NULL,  -- epoch ms
+    etag TEXT,
+    UNIQUE(slot_id, fetched_at)
+  );
+  CREATE INDEX IF NOT EXISTS notif_idx_contents_slot_time
+    ON notif_contents(slot_id, fetched_at DESC);
+
+  -- notif_deliveries: track many deliveries per slot/time
+  CREATE TABLE IF NOT EXISTS notif_deliveries(
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    slot_id TEXT NOT NULL,
+    fire_at INTEGER NOT NULL,     -- intended fire time (epoch ms)
+    delivered_at INTEGER,         -- when actually shown (epoch ms)
+    status TEXT NOT NULL DEFAULT 'scheduled',  -- scheduled|shown|error|canceled
+    error_code TEXT, error_message TEXT
+  );
+
+  -- notif_config: generic configuration KV
+  CREATE TABLE IF NOT EXISTS notif_config(

+# TimeSafari — Native-First Notification System
+
+**📝 SANITY CHECK IMPROVEMENTS APPLIED:** This document has been updated to clarify current background fetch infrastructure status and iOS implementation completeness.
+
+**Status:** Ready for implementation  
+**Date:** 2025-09-07  
+**Author:** Matthew Raymer
+
+---
+
+## Executive Summary
+
+Ship a **single, Native-First** notification system: OS-scheduled **background prefetch at T–lead** + **pre-armed** local notifications. Web-push is retired.
+
+### What we deliver
+
+- **Closed-app delivery:** Pre-armed locals fire even if the app is closed.
+- **Freshness:** One prefetch attempt per slot at **T–lead**; ETag/TTL controls; skip when stale.
+- **Android precision:** Exact alarms with permission; windowed fallback (±10m) otherwise.
+- **Resilience:** Re-arm after reboot/time-change (Android receivers; iOS on next wake/silent push).
+- **Cross-platform:** Same TS API (iOS/Android/Electron). Electron is best-effort while running.
+
+### Success signals
+
+- High delivery reliability, minute-precision on Android with permission.
+- Prefetch budget hit rate at **T–lead**; zero stale deliveries beyond TTL.
+
+---
+
+## Strategic Plan
+
+### Goal
+
+Deliver 1..M daily notifications with **OS background prefetch at T–lead** *(see Glossary)* and **rolling-window safety** *(see Glossary)* so messages display with fresh content even when the app is closed.
+
+### Tenets
+
+- **Reliability first:** OS delivers once scheduled; no JS at delivery time.
+- **Freshness with guardrails:** Prefetch at **T–lead** *(see Glossary)*; enforce **TTL-at-fire** *(see Glossary)*; ETag-aware.
+- **Single system:** One TS API; native adapters swap under the hood.
+- **Platform honesty:** Android exactness via permission; iOS best-effort budget.
+- **No delivery-time network:** Local notifications display **pre-rendered content only**; never fetch at delivery.
+
+### Architecture (high level)
+
+App (Vue/TS) → Orchestrator (policy) → Native Adapters:
+
+- **SchedulerNative** — AlarmManager (Android) / UNUserNotificationCenter (iOS)  
+- **BackgroundPrefetchNative** — WorkManager (Android) / BGTaskScheduler (+ silent push) (iOS)  
+- **DataStore** — SQLite
+
+**Storage:** **Current:** SharedPreferences (Android) / UserDefaults (iOS) + in-memory cache (see Glossary → Tiered Storage). **Planned:** one **shared SQLite** file (see Glossary → Shared DB); the app owns schema/migrations; the plugin opens the same path with **WAL** (see Glossary → WAL); background writes are **short & serialized**. *(Keep the "(Planned)" label until Phase 1 ships.)*
+
+### SQLite Ownership & Concurrency *(Planned)*
+
+* **One DB file:** The plugin will open the **same path** the app uses (no second DB).
+* **Migrations owned by app:** The app executes schema migrations and bumps `PRAGMA user_version` (see Glossary → PRAGMA user_version). The plugin **never** migrates; it **asserts** the expected version.
+* **WAL mode:** Open DB with `journal_mode=WAL`, `synchronous=NORMAL`, `busy_timeout=5000`, `foreign_keys=ON`. WAL (see Glossary → WAL) allows foreground reads while a background job commits quickly.
+* **Single-writer discipline:** Background jobs write in **short transactions** (UPSERT per slot), then return.
+* **Encryption (optional):** If using SQLCipher, the **same key** is used by both app and plugin. Do not mix encrypted and unencrypted openings.
+
+*Note: Currently using SharedPreferences (Android) / UserDefaults (iOS) with in-memory cache. See Implementation Roadmap → Phase 1.1 for migration steps.*
+
+### Scheduling & T–lead *(Planned)*
+
+- Arm **rolling window** (see Glossary → Rolling window). **(Planned)**
+- Exactly **one** online-first fetch at **T–lead** (see Glossary → T–lead) with **12s** timeout; **ETag/304** respected. **(Planned)**
+- If fresh **and** within **TTL-at-fire** (see Glossary → TTL), (re)arm; otherwise keep prior content. **(Planned)**
+- If the OS skips the wake, the pre-armed local still fires from cache. **(Planned)**
+
+*Note: Current implementation has basic scheduling and WorkManager infrastructure (Android) but lacks T–lead prefetch logic, rolling window logic, and iOS background tasks. See Implementation Roadmap → Phase 1-2.*
+
+### Policies *(Mixed Implementation)*
+
+- **TTL-at-fire** (see Glossary → TTL): Before arming for T, if `(T − fetchedAt) > ttlSeconds` → **skip**. **(Planned)**
+- **Android exactness** (see Glossary → Exact alarm): **(Partial)** — permission flow exists; finalize ±10m window & deep-link to settings.
+- **Reboot/time change:** **(Partial)** — Android receivers partially present; iOS via next wake/silent push.
+- **No delivery-time network** (see Glossary → No delivery-time network): Local notifications display **pre-rendered content only**; never fetch at delivery. **(Implemented)**
+
+---
+
+## Implementation Guide
+
+### 1) Interfaces (TS stable)
+
+- **SchedulerNative**: `scheduleExact({slotId, whenMs, title, body, extra})`, `scheduleWindow(..., windowLenMs)`, `cancelBySlot`, `rescheduleAll`, `capabilities()`
+- **BackgroundPrefetchNative**: `schedulePrefetch(slotId, atMs)`, `cancelPrefetch(slotId)`
+- **DataStore**: SQLite adapters (notif_contents, notif_deliveries, notif_config)
+- **Public API**: `configure`, `requestPermissions`, `runFullPipelineNow`, `reschedule`, `getState`
+
+### DB Path & Adapter Configuration *(Planned)*
+
+* **Configure option:** `dbPath: string` (absolute path or platform alias) will be passed from JS to the plugin during `configure()`.
+* **Shared tables:**
+
+  * `notif_contents(slot_id, payload_json, fetched_at, etag, …)`
+  * `notif_deliveries(slot_id, fire_at, delivered_at, status, error_code, …)`
+  * `notif_config(k, v)`
+* **Open settings:**
+
+  * `journal_mode=WAL`
+  * `synchronous=NORMAL`
+  * `busy_timeout=5000`
+  * `foreign_keys=ON`
+
+*Note: Currently using SharedPreferences/UserDefaults (see Glossary → Tiered Storage). Database configuration is planned for Phase 1.*
+
+See **Implementation Roadmap → Phase 1.1** for migration steps and schema.
+
+**Type (TS) extension** *(Planned)*
+
+```ts
+export type ConfigureOptions = {
+  // …existing fields…
+  dbPath: string;                 // shared DB file the plugin will open
+  storage: 'shared';              // canonical value; plugin-owned DB is not used
+};
+```
+
+*Note: Current `NotificationOptions` interface exists but lacks `dbPath` configuration. This will be added in Phase 1.*
+
+**Plugin side (pseudo)**
+
+```kotlin
+// Android open
+val db = SQLiteDatabase.openDatabase(dbPath, null, SQLiteDatabase.OPEN_READWRITE)
+db.execSQL("PRAGMA journal_mode=WAL")
+db.execSQL("PRAGMA synchronous=NORMAL")
+db.execSQL("PRAGMA foreign_keys=ON")
+db.execSQL("PRAGMA busy_timeout=5000")
+// Verify schema version
+val uv = rawQuery("PRAGMA user_version").use { it.moveToFirst(); it.getInt(0) }
+require(uv >= MIN_EXPECTED_VERSION) { "Schema version too old" }
+```
+
+```swift
+// iOS open (FMDB / SQLite3)
+// Set WAL via PRAGMA after open; check user_version the same way.
+```
+
+### 2) Templating & Arming
+
+- Render `title/body` **before** scheduling; pass via **SchedulerNative**.
+- Route all arming through **SchedulerNative** to centralize Android exact/window semantics.
+
+### 3) T–lead (single attempt)
+
+**T–lead governs prefetch, not arming.** We **arm** one-shot locals as part of the rolling window so closed-app delivery is guaranteed. At **T–lead = T − prefetchLeadMinutes**, the **native background job** attempts **one** 12s ETag-aware fetch. If fresh content arrives and will not violate **TTL-at-fire**, we (re)arm the upcoming slot; if the OS skips the wake, the pre-armed local still fires with cached content.
+
+- Compute T–lead = `whenMs - prefetchLeadMinutes*60_000`.
+- `BackgroundPrefetchNative.schedulePrefetch(slotId, atMs=T–lead)`.
+- On wake: **ETag** fetch (timeout **12s**), persist, optionally cancel & re-arm if within TTL.
+- Never fetch at delivery time.
+
+### 4) TTL-at-fire
+
+**TTL-at-fire:** Before arming for time **T**, compute `T − fetchedAt`. If that exceeds `ttlSeconds`, **do not arm** (skip). This prevents posting stale notifications when the app has been closed for a long time.
+
+`if (whenMs - fetchedAt) > ttlSeconds*1000 → skip`
+
+### 5) Android specifics
+
+- Request `SCHEDULE_EXACT_ALARM`; deep-link if denied; fallback to `setWindow(start,len)` (±10m).
+- Receivers: `BOOT_COMPLETED`, `TIMEZONE_CHANGED`, `TIME_SET` → recompute & re-arm for next 24h and schedule T–lead prefetch.
+
+### 6) iOS specifics
+
+- `BGTaskScheduler` for T–lead prefetch (best-effort). Optional silent push nudge.
+- Locals: `UNCalendarNotificationTrigger` (one-shots); no NSE mutation for locals.
+
+### 7) Network & Timeouts
+
+- Content fetch: **12s** timeout; single attempt at T–lead; ETag/304 respected.
+- ACK/Error: **8s** timeout, fire-and-forget.
+
+### 8) Electron
+
+- Notifications while app is running; recommend **Start-on-Login**. No true background scheduling when fully closed.
+
+### 9) Telemetry
+
+- Record `scheduled|shown|error`; ACK deliveries (8s timeout); include slot/times/TZ/app version.

+
+## Acceptance Criteria
+
+### Core
+
+- **Closed-app delivery:** Armed locals fire at T with last rendered content. No delivery-time network.
+- **T–lead prefetch:** Single background attempt at **T–lead**; if skipped, delivery still occurs from cache.
+- **TTL-at-fire:** No armed local violates TTL at T.
+
+### Android
+
+- **Exact permission path:** With `SCHEDULE_EXACT_ALARM` → within ±1m; else **±10m** window.
+- **Reboot recovery:** After reboot, receivers re-arm next 24h and schedule T–lead prefetch.
+- **TZ/DST change:** Recompute & re-arm; future slots align to new wall-clock.
+
+### iOS
+
+- **BGTask budget respected:** Prefetch often runs but may be skipped; delivery still occurs via rolling window.
+- **Force-quit caveat:** No background execution after user terminate; delivery still occurs if pre-armed.
+
+### Electron
+
+- **Running-app rule:** Delivery only while app runs; with Start-on-Login, after reboot the orchestrator re-arms and subsequent slots deliver.
+
+### Network
+
+- Content fetch timeout **12s**; ACK/Error **8s**; no retries inside lead; ETag honored.
+
+### Observability
+
+- Log/telemetry for `scheduled|shown|error`; ACK payload includes slot, times, device TZ, app version.
+
+### DB Sharing *(Planned)*
+
+* **Shared DB visibility:** A background prefetch writes `notif_contents`; the foreground UI **immediately** reads the same row.
+* **WAL overlap:** With the app reading while the plugin commits, no user-visible blocking occurs.
+* **Version safety:** If `user_version` is behind, the plugin emits an error and does not write (protects against partial installs).
+
+*Note: Currently using SharedPreferences/UserDefaults with in-memory cache. SQLite sharing is planned for Phase 1.*

+## Web-Push Cleanup
+
+Web-push functionality has been retired due to unreliability. All web-push related code paths and documentation sections should be removed or marked as deprecated. See `web-push-cleanup-guide.md` for detailed cleanup steps.
