Strict lockstep over-reported: the operand hook misses any op whose operands aren't fetched via vm_operand_fetch (comment 0x1a7, set-string 0x192, the 0x1c7/0x1cc/0x131/... string-op cluster) — the engine executes them (they sit after non-branching ops) but they're absent from its trace. New align() resyncs over such one-sided insertions and reports only NON-realignable forks; it separates VM-only blind spots (artifacts) from engine-only detours (real, reconverging branch/state gaps, surfaced honestly). +2 tests (7/7). Result: with G[0x6c1] seeded the SC0000 opening has NO non-realignable fork across all 539 VM ops (was: false 'diverge at 0x8d'); residual = a 2-op engine-only color detour (0x202/0x203 @ 0x122d0). Cold's first real fork is a later G[0x6c1] gate. Validates the pre-scene-state theory end-to-end. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
