# Changelog
## [6.0.0] - 2026-01-29
### Breaking Changes
- Legacy individual MCP tools removed from registration — all capabilities flow through 8 workflow tools + 3 cognitive tools
- Server decomposed from monolithic `server.py` (6,467 lines) into 149-line composition root + 15 tool modules under `daem0nmcp/tools/`
### Added
- **Auto-Zoom Retrieval Router**: Query-aware search dispatch (SIMPLE → vector, MEDIUM → hybrid, COMPLEX → GraphRAG) with shadow mode and fallback guarantees
- **JIT Compression**: Tiered automatic compression of retrieval results (soft >4K, hard >8K, emergency >16K tokens)
- **Background Dreaming**: Idle-triggered `FailedDecisionReview` with cooperative yielding and dream insight persistence
- **Cognitive Tools**: 3 new standalone MCP tools — `simulate_decision` (temporal scrying), `evolve_rule` (rule entropy), `debate_internal` (adversarial council)
- **Code-Augmented Reflexion**: Python assertion generation and sandboxed execution with failure classification
## [5.1.0] - 2026-01-26
### Breaking Changes

- Visual tools no longer standalone — accessed via `visual=True` parameter on workflow tools
### Changed
- All capabilities accessed through `commune`, `consult`, `inscribe`, `reflect`, `understand`, `govern`, `explore`, `maintain` workflow tools
- Each workflow tool accepts an `action` parameter to select the operation
- 60 total actions across 8 workflows

- **Metacognitive Architecture (Reflexion)**: Actor-Evaluator-Reflector loop via LangGraph, `verify_facts` tool, chain of verification
- **Context Engineering**: LLMLingua-2 integration (3x-6x compression), code entity preservation, `compress_context` tool
- **Dynamic Agency**: Ritual phase tracking, tool masking, `execute_python` sandboxed execution via E2B
- 7 new tools: `verify_facts`, `compress_context`, `execute_python`, `trace_chain`, `trace_evolution`, `get_related_memories`, `get_graph_stats`
