Degree of freedom: MIXED. Signature and batch sizing [HIGH freedom]; from-scratch re-search and the zero-hit gate [LOW freedom — run exactly].

How to reason

1. Observe — the old pattern's remaining hits from a fresh search
2. Interpret — planned files vs the real blast radius (tests, barrels, stories)
3. Classify — still-old / already-new / false-positive
4. Severity — leftover production call sites outrank a comment in CHANGELOG

Worked example

Observe: plan listed 8 files; fresh rg Button2 finds 14 (plus a story and a re-export). Interpret: the plan was a hypothesis; barrels were missed. Classify: 6 extra call sites still-old; CHANGELOG mention is false-positive. Done: re-search → 0 real hits; typecheck/lint/tests green.
