+# Developer & Agent Guide: Fadocx Optimization
+
+## Workflow Orchestration
+
+### 1. Plan Node Default
+- Enter plan mode for ANY non-trivial task (3+ steps or architectural decisions)
+- If something goes sideways, STOP and re-plan immediately - don't keep pushing
+- Use plan mode for verification steps, not just building
+- Write detailed specs upfront to reduce ambiguity
+
+### 2. Subagent Strategy
+- Use subagents liberally to keep main context window clean
+- Offload research, exploration, and parallel analysis to subagents
+- For complex problems, throw more compute at it via subagents
+- One tack per subagent for focused execution
+
+### 3. Self-Improvement Loop
+- After ANY correction from the user: update `tasks/lessons.md` with the pattern
+-Write rules for yourself that prevent the same mistake
+- Ruthlessly iterate on these lessons until mistake rate drops
+- Review lessons at session start for relevant project
+
+### 4. Verification Before Done
+- Never mark a task complete without proving it works
+- Diff behavior between main and your changes when relevant
+- Ask yourself: "Would a staff engineer approve this?"
+- Run tests, check logs, demonstrate correctness
+
+### 5. Demand Elegance (Balanced)
+- For non-trivial changes: pause and ask "is there a more elegant way?"
+- If a fix feels hacky: "Knowing everything I know now, implement the elegant solution"
+- Skip this for simple, obvious fixes - don't over-engineer
+- Challenge your own work before presenting it
+
+#### 6. Autonomous Bug Fixing
+- When given a bug report: just fix it. Don't ask for hand-holding
+- Point at logs, errors, failing tests - then resolve them
+- Zero context switching required from the user
+- Go fix failing CI tests without being told how
+
+## Task Management
+1. **Plan First**: Write plan to `tasks/todo.md` with checkable items
+2. **Verify Plan**: Check in before starting implementation
+3. **Track Progress**: Mark items complete as you go
+4. **Explain Changes**: High-level summary at each step
+5. **Document Results**: Add review section to `tasks/todo.md`
+6. **Capture Lessons**: Update `tasks/lessons.md` after corrections
+
+## Core Principles
+- **Simplicity First**: Make every change as simple as possible. Impact minimal code.
+- **No Laziness**: Find root causes. No temporary fixes. Senior developer standards.
+- **Minimal Impact**: Changes should only touch what's necessary. Avoid introducing bugs.
+
+---
+
+## Wasted App 2026 Revival - Mandatory Rules
+
+### Backward Compatibility Guarantee
+- **NEVER remove features**. Deprecated ≠ broken.
+- Device Admin API stays. If fixing Android 13+ issues, ADD permissions, don't replace.
+- minSdk 23 (Android 6) support MUST be maintained.
+- Old devices (Android 6-12): Device Admin only, no P2P.
+- New devices (Android 13+): Device Admin + P2P both available.
+
+### Execution Discipline
+- **Phase order is SACRED**. Do not parallelize or skip.
+ - Phase 1: API update + permissions (build foundation first)
+ - Phase 2: P2P networking (core system)
+ - Phase 3: UI + control (user-facing)
+ - Phase 4: Testing (integration + compat)
+- Each phase must PASS testing before next begins.
+- If Phase N breaks Phase N-1, STOP and re-plan.
+
+### Code Quality Standards
+- All networking code: Use TLS 1.2+ (OkHttp 4.11+)
+- All device communication: Encrypt with Tink (Google recommended)
+- All device data: EncryptedSharedPreferences + Room with encryption
+- No HTTP for control commands (TLS only).
+- No plain text device secrets.
+
+### Library Selection Principle
+- **Support maximum span**: Pick libs that work Android 6-16.
+- Prefer: OkHttp (API 21+), Gson (pure Java), Room (AndroidX), Tink (API 19+).
+- Avoid: Jetpack Compose (API 21+), experimental/alpha libs.
+- If adding a lib, verify minSdk support in official docs.
+
+### Testing Before Commit
+- Phase 1: Build + ForegroundService notification check.
+- Phase 2: Two real devices discover + pairing works.
+- Phase 3: Settings sync in < 500ms.
+- Phase 4: Full matrix tested (Android 6, 13, 15 minimum).
+- No feature commit without passing test on target API.
+
+### Documentation Requirements
+- Keep ROADMAP_2026_REVIVAL.md updated with actual progress.
+- If changing timeline, update roadmap with reason.
+- Lessons learned → /memories/session/lessons.md (for next session).
+- No silent pivots; document deviations.
+
+### Deprecation Handling (Critical)
+- Device Admin deprecated in Android 9 (2018) → Still use it, it works.
+- Respect the original code intent: lock device, wipe data, USB detection, inactivity timeout.
+- Treat P2P as ADDITION, not replacement.
+- When Device Admin is replaced (future), it's done AFTER P2P is stable.
+
+### Logging Standards (Extensive Tracking)
+
+**Log Levels:**
+- `VERBOSE`: Entry/exit of methods, variable state
+- `DEBUG`: Flow checkpoints, decision branches, API calls
+- `INFO`: User actions (lock triggered, wipe started, device paired)
+- `WARN`: Recoverable errors (retry pending, fallback activated)
+- `ERROR`: Failures requiring intervention (TLS failure, peer timeout)
+
+**Key Flows to Log:**
+
+1. **Device Admin Flow:**
+ ```
+ DEBUG: "lockNow() called"
+ DEBUG: "DevicePolicyManager.lockNow() invoked"
+ INFO: "Device lock triggered"
+ ERROR: "Device Admin not active" (if applicable)
+ ```
+
+2. **P2P Discovery Flow:**
+ ```
+ DEBUG: "mDNS discovery started"
+ DEBUG: "Searching for _wasted._tcp.local"
+ DEBUG: "Peer found: [device-name]"
+ INFO: "Pairing dialog shown"
+ DEBUG: "PIN validation: [status]"
+ INFO: "Pairing successful"
+ ```
+
+3. **Settings Sync Flow:**
+ ```
+ DEBUG: "Settings change detected: [key]=[value]"
+ DEBUG: "Broadcasting to [N] peers via TLS"
+ DEBUG: "ACK received from [peer-name]"
+ INFO: "Settings synced (latency: [ms])"
+ ERROR: "Sync failed for peer [name]"
+ ```
+
+4. **Reset Flow:**
+ ```
+ DEBUG: "Reset button clicked (local/remote)"
+ INFO: "Reset confirmation shown"
+ DEBUG: "User confirmed reset"
+ INFO: "wipeData() called" OR "Reset command sent to [peer]"
+ VERBOSE: "wipeData flags: [flags]"
+ ```
+
+**Log Tags:**
+- Use TAG constants: `DeviceAdminManager`, `P2PNetwork`, `SettingsSync`, `PairingManager`, `MessageQueue`, `SecurityManager`
+- One tag per class for easy filtering: `adb logcat DeviceAdminManager:* | grep -v VERBOSE`
+
+**Filtering on Device:**
+```bash
+# Watch all Wasted logs
+adb logcat | grep "Wasted"
+
+# Watch P2P discovery only
+adb logcat | grep "P2PNetwork"
+
+# Watch errors
+adb logcat *:E | grep -i wasted
+```
+
+**Testing Verification:**
+- Screenshot or save logcat when verifying flows
+- Document expected vs actual log sequences in test reports
+- Use logs to prove timing (latency <500ms for settings sync)
+- Archive logs per device for cross-device comparison
