    "Prototype function counters can include preceding rolled-back variants; use measured per-call time and digest, not per-variant derived function cost.",
    "Populated upgrade to.ref=worktree is dirty at HEAD 8a30feb5; actual SQL fingerprint and companion schema hashes identify the candidate.",
    "Fixed 10-year fixture has RPE8, so measured-reference index contains zero entries; dense measured index build cost is not inferred.",
    "v2 upgrade failed on a SQL dollar delimiter produced by the preparation script; corrected v3 is the valid migration evidence."
