• Callers stop being offered as hosts, and a broadcast refuses one. GET /personas answers with the whole roster, hosts and callers together, because the personas page draws both — so narrowing it is each surface's own job, and three of them had never done it: the on-air "Presented by" menu, "Hosted by" on a slot or a briefing box, and a production's presenter. Picking a caller there was not cosmetic. DirectorConsoleService.recast checked only that the persona existed, so the caller presented the show and SegmentRepository.recast rewrote every break in the tail in the character of somebody whose whole premise is that they are phoning in. recast now refuses a caller with the sentence PersonasService.setDefaultHost already used, and every console surface that offers a host narrows through one presents predicate rather than four copies of kind !== 'caller'. putOnAir still takes a persona id on trust, deliberately and for its own reason, so the endpoint half of that path is unchanged.
• "Hosted by" says the station's own host with an apostrophe. Its description carried ’ as six literal characters, and a JSX string attribute is HTML-like: it processes HTML entities but no backslash escapes, so every surface that draws this field — the slot editor, the briefing box and the sustaining panel — read "Empty means the station’s own host."
• The deadpan wisecracking host's checkable words are re-measured over 694 of her own scripts, after three auditions of the same playlist. that was a choice becomes was a choice, which catches the "That indeed was a choice" form that was being refused without being loose enough to insert as a noun; somebody was paid to, which fired on none of the 694, and marvellous, which fired on four, give their places to one might and perhaps. Her avoid list gains the critic's vocabulary the first pass missed — merely, exercise, substance, spectacle — and a persona's avoid cap rises from 12 to 16 so a sheet can forbid a whole register rather than a handful of phrases, which is what slacker and this character both need it for. Her diction now caps the number of her own phrases per break as well as the number of asides, since one audition break carried three.
