test(tui): headless session history reconstructed on hydration#206
Merged
Conversation
Adds a regression test exercising the full restart/reconnect hydration path (load_session_hydration → apply_transcript_to_local_state, including the SessionHydrationRequest.is_headless plumbing) against a mock daemon serving a PTY-less transcript of Message/Reasoning events. Asserts the headless prose + reasoning are folded back into the rebuilt ItemHistory when is_headless, and that a PTY-backed session does NOT re-render that transcript prose (it lives in the PTY stream).

Follow-up to #195 (render headless conversation in the TUI). That PR has rendering coverage, but no test asserting headless history is reconstructed on restart/reconnect. This adds one.
What it covers
Exercises the real hydration path —
load_session_hydration→apply_transcript_to_local_state— including theSessionHydrationRequest.is_headlessplumbing, against a mock daemon serving a PTY-less transcript ofMessage+Reasoningevents (what a headless session persists).is_headless: true): the rebuiltItemHistoryrenders the assistant prose ("Hello from headless") and reasoning ("considering options") — i.e. the conversation is restored on relaunch / after/agentd restart.is_headless: false): the same transcript'sMessageprose is not re-rendered (a PTY-backed session keeps its prose in the PTY stream, so replaying it would double it up).This guards the restart-reconstruction wiring that the rendering-only test (
transcript_replay_renders_messages_only_when_headless) doesn't reach.Verification
