Applying /code-review high findings on the review-follow-up stack:
- expeditionCmdStart: the resumable-extraction guard swallowed a partySize
error and fell open, starting a new expedition on top of a still-seated
party — the exact orphaning it exists to prevent. Now checks
extractionLapsed first (no DB call on the reap path) and treats a
roster-read error as "assume occupied → refuse".
- Lapsed reap on !expedition start silently unseated members. Extracted a
shared reapLapsedExtraction helper (reap + notify the roster) and routed
both the hourly sweeper and the start-path reap through it.
- stepRoundEnd: moved Misty's crowd/heal seat-loop after the concentration
tick so a caster whose lingering aura would kill the enemy that round wins
before the end-of-round crowd swing, honoring the concentration block's
"a lethal pulse settles the fight" intent.
- Promoted the misty_heal event-log scan to a shared hasAction helper.
- Renamed the new sweep test off the dnd_ prefix.
