The Claude Agent SDK loop (agent/hotpath_agent/loop.py, model claude-fable-5) drives the seven harness tools over a standalone stdio MCP server (mcp_server.py) and runs the full profile -> hypothesize -> patch -> gated-verdict cycle on comrak with no human in the loop. Three audited attempts, all honest rejections, ZERO false accepts: - phase2-comrak-001 class 3: syntect buffer with_capacity, [0.971,1.007] - phase2-comrak-002 class 5: gate dead VecDeque build, [0.982,1.026] - phase2-comrak-003 class 6: hoist find_special_char check, [0.970,1.007] The agent picked the cheapest untried class each time (3->5->6) and TWICE refused to fabricate a verdict it couldn't read back, verifying ledger integrity instead — the anti-reward-hacking behavior SPEC §10 targets. Harness changes surfaced by the loop: - run_verdict is now async: launches the multi-minute build+bench detached (past the 60s MCP transport cap) and returns immediately; new read_verdict op polls the append-only ledger row (ledger verdict_summary). Fixes attempt 001's unreadable-verdict gap. - read_target_source takes offset/limit line windows so 100KB+ files page instead of overflowing — removes the agent's reason to reach for a shell (attempt 003 paged a 2400-line file cleanly, no shell). Honest boundary note (case study + code comments): in THIS dev container the SDK tool allow/deny layer is defense-in-depth, not the trust boundary — a nested CLI as root under a parent session doesn't reliably gate built-ins. SPEC §10's boundary is OS process/user isolation; that hardening is the remaining Phase 2 exit item (docs/infra.md). What holds regardless: propose_patch is the only mediated write path (path-allowlist + git apply) and the ledger is append-only.
