A milestone whose target is in one month and whose forecast is in a later one showed no forecast marker in the later month: the marker was drawn only from entries already in the response, and a schedule with no occurrence in the window is never admitted.

• GET /workspaces/{ws}/agenda, GET /me/agenda and the collection calendar now return forecasts (with forecasts_complete): every visible live schedule whose forecast falls in the window, at most 500, earliest first. Visibility uses the same scope as the entries read. The list never counts toward entry caps, truncated, next_from or window_complete.
• The collection Month and the agenda Week draw these rows as forecast markers, deduplicated against a forecast already shown inline.
• docs/api.md updated in the three agenda sections.

Tests: store window edges and exclusions; forecast-only admission, a guest granted one item, an OAuth workspace allow-list and a pinned token on each endpoint; paging unchanged with 600 extra forecast-only schedules; vitest for both merges.
