 * Slice C of v2.11.1 — observability hook #7/7. Fire-and-forget per PRD Q4. The
 * synchronous emit never throws and never blocks the prereq check's return
 * value.
 *
 * Split out when `checkPrerequisites` gained the `emitEvents: false` opt-out:
 * the emit and the decision to skip it are one story, and the caller is over its
 * file-size cap. Body moved verbatim.
