+
+## Execution Plan
+
+### Phase 1: Specification (Day 1 Morning)
+```bash
+npx claude-flow@alpha sparc run specification "Analyze BrowserAdapter requirements based on NodeAdapter implementation and wa-sqlite documentation"
+```
+
+**Deliverable:** Complete specification of browser adapter requirements
+
+### Phase 2: Architecture (Day 1 Afternoon)
+```bash
+npx claude-flow@alpha sparc run architecture "Design BrowserAdapter implementation with OPFS persistence and IndexedDB fallback"
+```
+
+**Deliverable:** Architecture design document with implementation plan
+
+### Phase 3: TDD Implementation (Day 2)
+```bash
+npx claude-flow@alpha sparc tdd "Implement BrowserAdapter following the same interface as NodeAdapter, passing all 19 existing tests"
+```
+
+**Deliverable:** Working BrowserAdapter implementation with tests passing
+
+### Phase 4: Browser Testing (Day 2-3)
+```bash
+npx claude-flow@alpha sparc run testing "Setup Playwright and test BrowserAdapter in Chrome, Firefox, Safari with OPFS persistence"
+```
+
+**Deliverable:** Browser test suite with cross-browser validation
+
+### Phase 5: Review & Polish (Day 3)
+```bash
+npx claude-flow@alpha sparc run review "Review BrowserAdapter implementation, test coverage, and browser compatibility"
+```
+
+**Deliverable:** Final review report with any optimizations
+
+---
+
+## Parallel Execution Strategy
+
+Use claude-flow swarm coordination for parallel work:
+
+```bash
+# Initialize hierarchical swarm
+npx claude-flow@alpha swarm init --topology hierarchical --max-agents 5
+
+# Spawn specialized agents in parallel
+npx claude-flow@alpha swarm spawn specification "Analyze requirements"
+npx claude-flow@alpha swarm spawn architecture "Design implementation"
+npx claude-flow@alpha swarm spawn coder "Implement BrowserAdapter"
+npx claude-flow@alpha swarm spawn tester "Create test suite"
+npx claude-flow@alpha swarm spawn reviewer "Review quality"
+
+# Orchestrate tasks with dependencies
+npx claude-flow@alpha task orchestrate "Complete BrowserAdapter POC" \
+  --strategy adaptive \
+  --priority critical
+```
+
+---
+

+
+## Memory Coordination
+
+Each agent stores findings in shared memory:
+
+```bash
+# Specification agent stores requirements
+npx claude-flow@alpha memory store \
+  --key "browser-adapter/requirements" \
+  --value "<specification>"
+
+# Architecture agent reads requirements
+npx claude-flow@alpha memory retrieve \
+  --key "browser-adapter/requirements"
+
+# Coder agent stores implementation notes
+npx claude-flow@alpha memory store \
+  --key "browser-adapter/implementation" \
+  --value "<code-notes>"
+```
+
+---
+
+## Hooks Integration
+
+Use pre/post hooks for coordination:
+
+```bash
+# Before each agent task
+npx claude-flow@alpha hooks pre-task \
+  --description "Starting BrowserAdapter implementation"
+
+# After code changes
+npx claude-flow@alpha hooks post-edit \
+  --file "browser-adapter.ts" \
+  --memory-key "swarm/browser/implementation"
+
+# After task completion
+npx claude-flow@alpha hooks post-task \
+  --task-id "browser-adapter-poc"
+```
+
+---
+
+## Risk Mitigation
+
+### If OPFS doesn't work:
+- Fallback to IndexedDB (already planned)
+- Document browser compatibility matrix
+- Provide clear error messages
+
+### If performance is too slow:
+- Profile bottlenecks with benchmarking agent
+- Optimize hot paths
+- Document acceptable performance ranges
+
+### If tests fail in browser:
+- Use Playwright debugger
+- Add detailed error logging
+- Test each browser individually
+
+---
