Share exact coordinate selection across retained graph, projection and call-boundary values. Index inverse operand occurrences for values without requiring defining operations; preserve PHI slots, unknown spaces, partial scope and evidence. Verify 250 OpenSSH SSA versions and 369 uses through both real MCP adapters. An equivalent retained-source task takes six core reads instead of 244; model costs and native speedups remain unproved. Pass 78 shared tests and actual catalog checks. Co-authored-by: gensokyo-dev <[email protected]> Co-authored-by: Kaoru0822 <[email protected]>
