Snowflake MCP upgrade plan APPROVED for execution pending AJ go/no-go:…

Decision

Snowflake MCP upgrade plan APPROVED for execution pending AJ go/no-go: v22.0.0 / Bible v19.1.7 / +79 tools / -5 Gen 1 hard-banned with -32006 + 3 migration helpers / single coordinated cutover / Tier 1 R&D classification / 22-25 focused hours / inline presentation per new feedback rule.

Rationale

Reasoning chain (session 799004d, 5 thoughts) supports the plan. Observation thought (#3, conf 0.98) confirms 11 of 12 Bible v19.1.7 checks fail/partial including the 5 Gen 1 wire-violations and system-wide Check 12 across all 856 tools. Analysis thought (#4, conf 0.85) justifies the two structural choices: HARD-ban over soft-remove (in-band agent signal, blocks raw-SQL bypass) and single-cutover over split (one Contract sign, one census, one cascade, one operator review). Conclusion thought (#5, conf 0.85) confirms plan correctness pending Phase 0.5 health census BROKEN-count threshold (>60 = surface to AJ before Phase 4). Premortem (active session) surveyed 5 failure categories; 5 material risks captured in plan §Risk Posture with explicit phase-ordering mitigations. Setup-curator gated the new feedback file write (8 anti-bloat filters passed, MEMORY cascade complete at 157 lines / 200-line cliff = 21% safety buffer).
