The lineup fix and the new characters both land in main.py, so they share a commit rather than being split artificially. Lineup fix — populate_backgrounds() was reachable only through POST /api/session/reset, so taking calls without hitting reset left session.caller_backgrounds empty for a whole show. Every caller got a hollow prompt, collapsed into generic relationship filler, and Silas lost his lore. Now start_call populates on demand, get_caller_prompt raises EmptyCallerBackgroundError instead of emitting an empty prompt, /api/callers reports lineup readiness to a header badge, and cross-episode topic dedup widened from 2 shows to 10. Wellspring callers — Doyle as the anchor defector plus a six-member pool, grouped by new frontmatter fields (group, group_lead, group_weight, register, explicitness). A faction is capped at one caller per show, with a 15% roll for two pairing the lead with one other member. group_weight lets an anchor carrying an arc get slots faster than texture characters. Also detects model refusals, which arrive as ordinary 200s and previously reached air as broken-character text or dead silence. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
