Resident agents call GET /api/exploration/patrol once per cycle to see
every running production-line campaign that opted into exploration
(seed set present), the new results since the last watermark (reusing
campaign report aggregation), and the remaining exploration budget.
The watermark advances after each call so subsequent calls only report
increments; accelerated and terminal campaigns are excluded.
Introduce ModelPurpose.ANALYSIS and a globally-unique is_analysis_default
marker on chat model configs so campaign analysis can resolve its model.
Service rejects disabled or non-chat configs; repo clears the previous
holder on set. Documented the analysis role in CONTEXT.md.
build_campaign_timeline flattens a campaign's child Runs into offset-sorted
per-Run entries (distinct from the report's 12-bucket aggregation), reusing a
shared _run_window_offset口径 so both views place a run identically. Exposes
GET /campaigns/{id}/timeline and the api.ts type/call. (v0.6 ticket 06)
