  1. 01
    EventStream
    Representative 120×40 terminal state.

    Passive paint
    No keyboard or pointer action is claimed by this representative story.

Purpose. Structured event consoles (k8s events, agent activity, observability)
where rows are typed, not freeform log lines. Distinct from
LogStream (text+level) and
Timeline (presentation recipes).

Live + unread


    

  • Follow tail by default (ScrollAreaState authority).
    • 

  • Scroll/move up detaches; chip shows ↓ N new.
    • 

  • Host calls on_append(total, viewport) after each project.
    • 

  • report_backpressure(dropped, batched) for drop/batch chrome.
    • 



Pluggable summary / detail


    

  • summary — one-line host-formatted row body.
    • 

  • fields — optional k=v chrome (dropped when narrow).
    • 

  • detail — inspector body when selected (i / Enter).
    • 

Ownership boundary
TermRock owns reusable terminal rendering and interaction state. The host owns domain data, policy, persistence, authorization, and side effects.
Evidence status
1 covered, 10 partial, and 5 missing contract axes. Missing evidence is not a behavior claim.
Diff View
A vertically scrollable, syntax-neutral presentation of projected diff lines.
File Tree
FileTree is the exact public paint owner for data terminal UI.
