Implementer notes (P9 steer)

  1. One component, three hosts. PlanTimeline is presentational; pure lane/bar/cursor math in *_helpers.ts (Vitest). Hosts supply {tasks, hHour, cursor, taskStates, editable}. Orders editor (P8) is the editable host; COP and Replay render read-only with a cursor.
  2. Placement. Collapsible bottom panel in the same slot family as the comms panel — never a map overlay, never a COP view toggle. Collapsed state = one-line strip: plan name, version, now-position, past-due count.
  3. COP host. Tasks from the operation's current plan tree (latest seq per plan id). Now-line ticks live. Task state derives from reports: complete (report received covering the task window), in-window, past due + unreported = red — the visual sibling of the silent-unit rule in the compliance matrix. Click bar = task detail + that unit's latest report. Unit lanes by default; expand a unit for callsign lanes.
  4. Replay host. Plan folded from the plan NDJSON layer: at cursor T render the highest seq ≤ T per plan id (same fold-forward as orbat_change / target_transition). Version chip shows which seq is active and when superseded. Task states computed from reports ≤ T only — no future knowledge leaks. Plan-publish moments render as marks on the replay scrubber.
  5. No compat. sync_task export layer removed in the same storm; plan layer replaces it outright.
  6. ORBAT at T. Replay lanes use ORBAT as at cursor (fold orbat_change), so a provisional team formed mid-op appears in lanes only after its formation moment.
  7. Not pixel spec. daisyUI + waypoint tokens; state colours map to NATO-aligned status tokens already in the theme.
