What the mounted story proves
  1. 01
    SubagentCard
    Representative 120×40 terminal state.
  2. 02
    Passive paint
    No keyboard or pointer action is claimed by this representative story.
  3. 03
    Evidence stays explicit
    0 covered · 9 partial · 5 missing axes.
03 · Implement
Install, then start from exact code
Install
cargo add termrock --git https://github.com/tailrocks/termrock.git --rev 5283c2acf9154d0cfcd37b1ffe821c00faf90ea2
Add TermRock once. Keep domain effects in the host application.

Advanced guidance
Authored implementation guidance
Card/row for nested agent runs. Shows role, task, provenance, status, model/mode,
context, progress, summary, and preview. Active cards use a host-ticked quiet
pulse and expanded actor rail; completed cards use semantic outcome marks.
Outcomes request steer/message/cancel/… — TermRock never runs agents.

Ownership boundary
TermRock owns reusable terminal rendering and interaction state. The host owns domain data, policy, persistence, authorization, and side effects.
Evidence status
0 covered, 9 partial, and 5 missing contract axes. Missing evidence is not a behavior claim.
