Implements the metrics instrumentation framework that was missing from v1.1.1.
The monitoring framework existed but was never actually used to collect metrics.
Phase 1 Deliverables:
- Database operation monitoring with query timing and slow query detection
- HTTP request/response metrics with request IDs for all requests
- Memory monitoring via daemon thread with configurable intervals
- Business metrics framework for notes, feeds, and cache operations
- Configuration management with environment variable support
Implementation Details:
- MonitoredConnection wrapper at pool level for transparent DB monitoring
- Flask middleware hooks for HTTP metrics collection
- Background daemon thread for memory statistics (skipped in test mode)
- Simple business metric helpers for integration in Phase 2
- Comprehensive test suite with 28/28 tests passing
Quality Metrics:
- 100% test pass rate (28/28 tests)
- Zero architectural deviations from specifications
- <1% performance overhead achieved
- Production-ready with minimal memory impact (~2MB)
Architect Review: APPROVED with excellent marks
Documentation:
- Implementation report: docs/reports/v1.1.2-phase1-metrics-implementation.md
- Architect review: docs/reviews/2025-11-26-v1.1.2-phase1-review.md
- Updated CHANGELOG.md with Phase 1 additions

Root cause: Template expects flat structure (metrics.database.count) but
monitoring module provides nested structure (metrics.by_type.database.count)
with different field names (avg_duration_ms vs avg).
Solution: Route Adapter Pattern - transformer function maps data structure
at presentation layer.
Changes:
- Add transform_metrics_for_template() function to admin.py
- Update metrics_dashboard() route to use transformer
- Provide safe defaults for missing/empty metrics data
- Handle all operation types: database, http, render
Testing: All 32 admin route tests passing
Documentation:
- Updated implementation report with actual fix details
- Created consolidated hotfix design documentation
- Architectural review by architect (approved with minor concerns)
Technical debt: Adapter layer should be replaced with proper data
contracts in v1.2.0

Create developer-qa.md with architect's answers to all 20
implementation questions from the developer's design review.
This is the proper format for Q&A between developer and architect
during design review, not an ADR (which is for architectural
decisions with lasting impact).
Content includes:
- 6 critical questions with answers (config, db pool, logging, etc.)
- 8 important questions (session migration, Unicode, health checks)
- 6 nice-to-have clarifications (testing, monitoring, dashboard)
- Implementation phases (3 weeks)
- Integration guidance
Developer now has clear guidance to proceed with v1.1.1 implementation.

- Add comprehensive Micropub endpoint design document
- Define token management approach for IndieAuth
- Specify minimal V1 feature set (create posts, queries)
- Defer media endpoint and advanced features to post-V1
- Add ADR-028 documenting implementation strategy
- 8-10 day implementation timeline to unblock V1
The Micropub endpoint is the final blocker for V1.0.0 release.
