11 improvements across 4 priority tiers, all integrated into production
code paths with 416 new tests across 33 test files. Each wave passed
a brutal honesty audit with all findings resolved.
Wave 0-2 (P0/P1): Middleware chain, microcompact, tool concurrency,
retry engine, session durability, prompt cache latch, startup fast
paths, hook security hardening.
Wave 3 (P2): 4-tier context compaction pipeline, plugin architecture
with local/GitHub/npm sources.
Wave 4 (P3): QE Quality Daemon — priority queue, git watcher (with
Linux polling fallback), coverage delta analyzer, CI monitor, test
suggester, nightly consolidation, notification service with SSRF guard,
persistent SQLite-backed memory, CLI commands, MCP startup integration.
