Idle bot turns confess; the chronicle fills its gaps

A clockwork whose chosen command the engine refuses now stumbles
visibly: the refusal is logged server-side with the offending command
(the RNRX coma took three silent turns to notice), and the bot says
so in character at the table — "RECALCULATING." — instead of an
unexplained idle turn. And six event types that never spoke in the
chronicle find their lines: the wave's wash-back, thornbush entry,
dragged objects, the opening deal, stolen-card and revealed-hand
privates. Replay captions inherit them all through humanize.
