Post-check: possible forgotten references

A deterministic sweep ran after the LLM's plan was applied in memory; the lines
below still match the previous minor and were not in the skipped list, so
they may have been overlooked. Please verify — these are most often historical
comments or test fixtures, but occasionally indicate a missed bump.

(none — post-check found no leftover references.)
