commit dffa821c38dfe049482962748ef1458a9e01a5e43ce049cc343ce14337b76949

    feat: Guildhouse MCP server + multi-agent governed dev pipeline
    
    MCP server connecting Claude Code to the Guildhouse ecosystem.
    
    Tools (23):
      Forgejo: repos, files, branches, PRs, CI status
      Chronicle: events, epochs, verify, emit
      GSAP proxy: request_ac, check_operation, get_posture, delegate
      Capstone: agents, tenants
      Tasks: list, get, create, update_status, submit_for_review, submit_review
    
    Multi-agent topology:
      Lead Agent — plans work, delegates, reviews proposals
      Worker Agents — implement in parallel, submit PRs with confidence
      Reviewer Agent — QA's worker output, submits review confidence
      Confidence Gate — auto-merge/flag/propose/reject based on combined score
    
    Confidence thresholds (configurable):
      >= 85: auto-merge (no human needed)
      >= 70: flag-merge (merged, flagged for post-review)
      >= 50: proposal (Tyler reviews)
      < 50: reject (worker revises)
    
    Reviewer can override: 'reject' always rejects, 'request_changes'
    caps at propose.
    
    Task definitions (TOML) with phased prompts, success criteria,
    and delegation scopes.
    
    Every tool call emits Chronicle MCP_TOOL_CALL (0x3020).
    Every gate decision emits Chronicle events (0x4010-0x4013).

+# CLAUDE.md — Guildhouse MCP Server
+
+## What is this?
+
+MCP server connecting Claude Code to the Guildhouse ecosystem: Forgejo, Capstone, GSAP governance, Chronicle audit, and K8s/Flux.
+
+## Structure
+
+- `src/guildhouse_mcp/server.py` — FastMCP server with 25+ tools
+- `src/guildhouse_mcp/tools/` — Backend implementations (forgejo, chronicle, capstone, gsap_proxy, tasks)
+- `src/guildhouse_mcp/agents/` — Multi-agent orchestration (confidence gate, topology)
+- `tasks/` — TOML task definitions with phased prompts
+
+## Commands
+
+```bash
+pip install -e ".[dev]"
+python -m guildhouse_mcp              # Run MCP server (stdio)
+python -m pytest tests/               # Run tests
+```
+
+## Key Concepts
+
+- **Confidence gate**: Combined worker (40%) + reviewer (60%) score decides auto-merge/flag/propose/reject
+- **Chronicle recording**: Every tool call emits MCP_TOOL_CALL (0x3020) event
+- **GSAP proxy**: Forwards governance tool calls to existing GSAP MCP broker
+- **Task definitions**: TOML files with phases, success criteria, delegation scopes
+
+## Thresholds (configurable via env)
+
+- `GUILDHOUSE_AUTO_MERGE_THRESHOLD=85` — No human needed
+- `GUILDHOUSE_FLAG_MERGE_THRESHOLD=70` — Merged, flagged for post-review
+- `GUILDHOUSE_PROPOSAL_THRESHOLD=50` — Tyler reviews
+- Below 50 — Rejected, worker revises
