First env edit not being applied (thanks @17307)

Editor assessment

`fix: first env edit not being applied (thanks @17307)` states the symptom — the first edit silently dropped — and credits a reporter; the parenthetical thanks is an acceptable stylistic touch. A variables scope would have localized it, minor. Fix fits a missed-update bug. No body explains the stale-state cause — the instructive mechanism — but the subject identifies exactly when the bug manifests. No junk footers. Imperative-equivalent noun phrase, no trailing period. Clear, correct, and publishable with a minor mechanism gap.
