After an exploration session closes, the platform samples up to 3
conversation rounds and runs an independent judge-role review through
the v0.7 ChatClient seam, persisting quality-dimension conclusions
(attitude, professionalism, hallucination) into the session's
judge_review. The review runs as a background task: failures are
recorded without touching session state or the first-hand experience
record, and a missing model config skips silently.
v0.9 ticket 02. Campaigns now carry an exploration seed set (seed
personas × seed goals — the comparability unit for exploratory
evaluation) and an optional budget override, stored as JSON columns
isomorphic to plan. Empty seeds normalize to null, marking the campaign
as opted out of exploration. resolve_budget merges per-field overrides
into platform defaults; enforcement stays server-side. The create form
gains seed lists and budget inputs (minutes → seconds), submitting null
when left empty.
v0.9 ticket 01. Independent exploration_sessions/exploration_messages
entities (never merged into EvalRun, keeping ADR-0001/0002 semantics
intact): create/message/close APIs forward virtual-user messages through
the target's real channel, persist both parties' rows with latency, and
close with a whitelist-normalized experience record. Budget enforcement
is a platform ledger — sessions per window, turns per session, and
session interval overruns return 409 with readable reasons; accelerated
lines accept manual sessions only. Messages delivered but unanswered
still consume a turn so timeouts cannot bypass the budget.
