# Architectural Decision: Phase 2.1 Blocking Issue

**Date**: 2026-02-06
**Status**: DECISION REQUIRED
**Impact**: Phase 2.1 cannot proceed to Task 8 without resolution

## Issue

Phase 2.1 (napi-rs Node.js Bindings) Tasks 6-7 depend on Phase 1.3 (Gossip Overlay Integration) which is not yet complete. 

**Current State**:
- Phase 1.1 & 1.2: COMPLETE (Identity, Network Transport)
- Phase 1.3: PENDING (Gossip Overlay Integration) ← BLOCKING
- Phase 1.4: PENDING (CRDT Task Lists)
- Phase 1.5: COMPLETE (MLS Group Encryption)
- Phase 2.1: BLOCKED (cannot proceed without 1.3 & 1.4)

## Blocking Tasks

**Task 6**: TaskList creation and join bindings
- Requires: TaskListHandle from Phase 1.4 (CRDT Task Lists)
- Current: Agent::createTaskList() and Agent::joinTaskList() not yet implemented in Rust core
- Status: PARTIALLY COMPLETE (only TaskList operations exposed, not creation/join)

**Task 7**: TaskList operations bindings
- Requires: Same as Task 6
- Status: WAITING

## Available Options

### Option A: Skip to Task 8 (Recommended)
- Continue with WASM Fallback build (Task 8) which doesn't depend on Phase 1.3/1.4
- Return to Tasks 6-7 after Phase 1.3 & 1.4 are complete
- **Pros**: Unblocks progress, maintains momentum
- **Cons**: Creates dependency ordering complexity

### Option B: Implement Stubs
- Create mock/stub TaskList::create() and TaskList::join() that return errors
- Allows Task 6-7 to be marked complete
- Replace with real implementation later
- **Pros**: Sequential task progression
- **Cons**: Spreads work across multiple commits, pollutes codebase with test code

### Option C: Pause Phase 2.1
- Wait for Phase 1.3 & 1.4 to complete before resuming
- **Pros**: Clean dependency ordering
- **Cons**: Blocks entire phase, extends timeline

## Recommendation

**OPTION A: Skip to Task 8**

Rationale:
1. Task 8 (WASM Fallback) is independent and unblocked
2. Maintaining momentum across different task types reduces cognitive overhead
3. Tasks 6-7 can be revisited once Phase 1.3-1.4 are complete
4. This is consistent with GSD practices of working around blockers

## Next Action

To proceed with GSD autonomous execution:
1. Move to Task 8 (WASM Fallback Target Build)
2. Complete Tasks 8-12 which are unblocked
3. Return to Tasks 6-7 after Phase 1.3-1.4 are complete
4. Phase 2.1 completion requires all 12 tasks

## Impact on Timeline

- **Current Blocked**: Tasks 6-7 (2 tasks)
- **Unblocked Ready**: Tasks 8-12 (5 tasks)
- **Estimated Rework**: 4-6 hours for Tasks 6-7 once dependencies available

---

**Awaiting Human Confirmation**: Proceed with Option A (continue with Task 8)?
