Sprint 153 Plan: Multi-Language Determinism and Replay Qualification

Context

Sprint 153 formalizes replay and determinism qualification across languages so constructive loop behavior can be trusted and audited before GA.

---

Goals

1. Build replay corpus and golden outcomes for multiple languages
2. Detect divergence in AST, text, merge, and diagnostics outputs
3. Classify determinism failures with actionable root causes
4. Publish qualification status consumable by release gates

Steps

Step 1769: Multi-language replay corpus schema (10 tests)

Step 1770: Golden outcome comparator model (10 tests)

Step 1771: Divergence classification and triage model (10 tests)

Step 1772: Determinism gate policy model (10 tests)

Step 1773: whetstone_run_constructive_replay_suite MCP tool (8 tests)

Step 1774: whetstone_compare_constructive_replays MCP tool (8 tests)

Step 1775: whetstone_get_determinism_gate_status MCP tool (8 tests)

Step 1776: Determinism qualification packet model (8 tests)

Step 1777: Replay and determinism report artifact (8 tests)

Step 1778: Sprint 153 integration summary + regression (8 tests)

Architecture Gate

• Replay must be reproducible with explicit environment fingerprinting
• Divergence packets must be structured and field-level traceable
• Determinism gate outcomes must be binary, auditable, and policy-bound
• Max 600 lines per header
