+
+**Stats:**
+
+- 12 files created/modified
+- 2,973 lines Python (plugin), 3,062 lines Python (tests)
+- 6 phases, 15 plans, 47 requirements (100% coverage)

+
+**Git range:** `33ede2f` → `c159a4d`

 ## What This Is
 
-A comprehensive refactoring of the Netro Sprinklers Indigo plugin to eliminate technical debt and improve code quality. The plugin currently works in production (v2.0 with multi-controller support) but has accumulated quality issues including bare exception handlers, monolithic architecture (1635 lines), and gaps in test coverage.
+A production-ready Netro Sprinklers Indigo plugin with clean, modular architecture (v1.0 refactoring complete, Feb 2026). The plugin provides reliable smart irrigation control with comprehensive test coverage (95%), proactive API throttle management, and maintainable code structure across 7 focused modules.

 ### Active
 
-**Code Quality & Architecture:**
-- [ ] Eliminate all bare exception handlers (replace with specific exceptions + logging)
-- [ ] Split plugin.py into focused modules (api_client, validators, utils, actions)
-- [ ] Achieve Pylint 8.0+ score (currently 6.5/10)
-- [ ] Extract timestamp parsing to single utility function
-- [ ] Improve logging consistency (correct levels: debug/info/warning/error)
-- [ ] Use f-strings exclusively for string formatting
-
-**Error Handling & Reliability:**
-- [ ] Add specific exception handling throughout (requests.Timeout, KeyError, ValueError)
-- [ ] Log all exceptions with full traceback
-- [ ] Wrap individual API calls with targeted error handling
-- [ ] Fix concurrent thread exception handling (no silent failures)
-- [ ] Implement proactive rate limit prevention (pause polling when tokens <100)
-- [ ] Persist throttle state across plugin restarts
-
-**Testing:**
-- [ ] Add comprehensive Whisperer sensor tests
-- [ ] Add error path tests (network timeouts, API 500s, malformed JSON)
-- [ ] Add edge case tests (unicode names, empty moisture lists, schedule parsing)
-- [ ] Improve overall coverage to 75%+
-
-**Features:**
-- [ ] API response schema validation (detect format changes early)
-
-**Development Workflow:**
-- [ ] Create GitHub issues for all major work items
-- [ ] Tie commits and PRs to GitHub issues
-- [ ] Update CHANGELOG.md with issue references
+(To be defined for next milestone. Use `/gsd:new-milestone` to plan v2.0)
+
+**Potential future work:**
+- Remove unused exception classes (NetroConnectionError, NetroTimeoutError)
+- Further extract action/menu handlers from plugin.py (optional)
+- Add explicit API version tracking (currently implicit via schema validation)
+- Historical moisture graphing
+- Zone usage statistics
 
 ### Out of Scope
 
-- Multi-controller support — Already implemented in v2.0 (device-level serial numbers)
 - Serial number redaction in logs — Local Mac logs, not a security concern
 - Per-device polling configuration — Not needed, adds complexity
-- Historical moisture graphing — Feature request for future version
-- Zone usage statistics — Feature request for future version
 - Webhook support — Netro API doesn't provide webhooks
+- Real-time push notifications — API is polling-only
 
 ## Context
 
-**Existing Architecture:**
-- Production-ready Indigo plugin (v2.0, Jan 2025 overhaul)
+**Current State (v1.0, Feb 2026):**
+- Production-ready Indigo plugin with modular architecture
 - Python 3.10+ for Indigo 2023.2+
-- Single 1635-line plugin.py file
+- 7 focused modules: constants (117 lines), exceptions (151 lines), utils (61 lines), api_client (644 lines), validators (510 lines), device_handlers (452 lines), plugin (1038 lines)
+- Total: 2,973 lines plugin code, 3,062 lines test code
 - Netro Public API v1 integration (REST with 2000 calls/day limit)
 - Supports Sprite, Pixie, Spark controllers + Whisperer sensors
-- 64 automated tests (pytest), >70% coverage
+- 247 automated tests (pytest), 95% coverage on testable modules
 - Tested with real hardware ("Clark Castle Spark" controller, 16 zones)
 - GitHub repository: https://github.com/simons-plugins/netro-indigo
 
-**Known Issues Identified:**
-- 10 documented API quirks (timestamp formats, response structures)
-- Bare exception handlers at 5+ locations (masks bugs)
-- Large single file (hard to navigate, test, maintain)
-- Timestamp parsing duplicated in 4+ places
-- Whisperer sensor code undertested
-- Throttle state lost on plugin restart
-- Thread dies silently on errors (line 827: `except (Exception,): pass`)
+**Issues Resolved (v1.0):**
+- ✓ Eliminated all bare exception handlers
+- ✓ Modular architecture with clean separation of concerns
+- ✓ Comprehensive test coverage (tripled from baseline)
+- ✓ Proactive throttle management with state persistence
+- ✓ API schema validation for early detection of format changes
