Implements the learned adapter hints layer with governance guardrails: - HintFeatureExtractor: extract features from decision ledgers (step 859) - HintModelInterface: pair-specific hint query interface (step 860) - DeterministicFallback: safe fallback when hints unavailable (step 861) - HintConfidencePacket: confidence bands and escalation logic (step 862) - HintABHarness: A/B harness to measure hint effectiveness (step 863) - HintRollbackControl: suppress and lift hint suppression per pair (step 864) - whetstone_get_adapter_hints MCP tool (step 865) - whetstone_set_hint_policy MCP tool (step 866) - HintSafetyGuardrails: non-authoritative enforcement + audit (step 867) - Sprint63IntegrationSummary (step 868) All 10 steps passing (94 tests). Governance rule: learned hints may suggest; deterministic policy decides. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
