Sprint 127 Plan: Deterministic Debug Assist Packets

Context

Sprint 126 added checkpointing/resume/export for campaigns. Sprint 127 focuses on making debugging guidance more explicit and machine-friendly so smaller agents can follow constrained steps reliably.

---

Goals

1. Add deterministic hint and triage models
2. Add bounded repro reduction and patch risk labeling models
3. Add MCP tools for hinting/triage/repro/risk
4. Preserve deterministic outputs and machine-readable packets

Steps

Step 1509: Debug hint template model (10 tests)

Step 1510: Failure triage score model (10 tests)

Step 1511: Minimal repro reducer model (8 tests)

Step 1512: Patch risk labeler model (8 tests)

Step 1513: whetstone_generate_debug_hints MCP tool (8 tests)

Step 1514: whetstone_score_failure_triage MCP tool (8 tests)

Step 1515: whetstone_reduce_repro_command MCP tool (8 tests)

Step 1516: whetstone_label_patch_risk MCP tool (8 tests)

Step 1517: Debug assist packet bundle model (8 tests)

Step 1518: Sprint 127 integration summary + regression (8 tests)

Architecture Gate

• Hints and scores must be deterministic for identical inputs
• Repro reduction must be bounded and machine-readable
• Risk labels must include explicit rationale and level
• Max 600 lines per header
