This run moved Gantry's visible stop experience into the assistant pane while leaving the engine stop model alone. The work mattered because the old full-screen surface hid the transcript at the moment an operator most needed the stopped run's context, and it carried its own rendering, input, selection, and replay rules.
The decomposition treated that as a front-end routing change with follow-through. A new transcript entry contract came first, the obsolete overlay path was deleted after that contract existed, demo and filming behavior were taught to show the new surface, and the documentation inventory was refreshed to match the shipped interface.
How this walkthrough is structured
Feature
What did the run build and ship?
The current tree still shows stopped and paused runs as durable assistant transcript entries, while replay, demo, recent-events, status, and documentation describe the non-modal surface.
Build
How did Gantry structure the work?
The run used one milestone to move stop handling from modal ownership to transcript routing, with the only red gate landing where the new assistant entry contract was established.
Milestone 1
Transcript Stop Flow
4 tasks 12 agents 54m 2s wall time 175k peak context
The front-end now has one live stop presentation: an assistant-pane entry with the resolved title, body, report text, and paused versus stopped state. Recent-events still reopen a past stop as read-only history, while the status bar and durable records continue to carry the stopped state. The old overlay's live responsibilities are gone from the current interface.
This milestone carried the whole front-end change as a single route from stop event to assistant transcript. Its brief was broad but still bounded for a fresh agent because it excluded engine semantics, headless output, status records, and generated stop content from the design problem. The milestone-level review stayed green after the nested sprints landed, so the final integration work was cleanup of obsolete assertions rather than a new design pass.
Route Stop Entry
3 agents 14m 58s wall time 175k peak context 1 fix
`src/tui/state.rs` still resolves stop titles and bodies when the event is folded, reads diagnosis reports into the stored body, and pushes a stop-role chat message. Tests still cover generated cards, missing report fallback, read-once report behavior, pane restoration, and the recent-events snapshot. `src/tui/render.rs` renders that body through the transcript markdown path rather than modal chrome.
This sprint was the contract slice for everything that followed. It had to fold stopped and paused run events into an engine-originated transcript entry, resolve report text once, preserve recent-events history, and bring the assistant pane to the new entry without stealing composer focus. The gate went red here and then repaired, which locates the difficult boundary at the first moment the stop model crossed into chat state and rendering.
Remove Stop Overlay
2 agents 15m 4s wall time 164k peak context
Live stops no longer open a frontmost stop overlay in the TUI. The surviving code routes stop events through the assistant entry, leaves ordinary global quit handling in place, and keeps only the read-only recent-events modal snapshot for historical lookup. Documentation and tests no longer describe the deleted overlay as the live stop path.
With the transcript entry available, this sprint could be a deletion boundary instead of another routing experiment. Its brief asked for the full-screen stop surface to stop owning draw, input, mouse, scrolling, selection, help text, overlay ordering, and replay suppression, while keeping recent-events history intact. It passed through review and gate without recorded repair, which fits a bounded removal over a proven replacement.
Update Demo Replay
2 agents 8m 5s wall time 114k peak context
The demo now writes a diagnosis report that exercises the same read-once stop body path as a live run and describes the assistant-pane stop entry on screen. Screencast-enabled tests assert that filmed replay carries the stop text in the transcript, records the event, and does not place a blocking overlay over the frame. The replay handover also names the removed overlay as a reason clips needed regeneration.
This sprint followed the UI change into recorded and scripted surfaces. The brief was deliberately narrower than the core routing work: the demo stop had to narrate the transcript entry, and filmed replay had to show that entry while continuing past it. The run stayed green, so the replay consequence was handled as expected behavior rather than as a compatibility failure to suppress.
Update Overlay Docs
2 agents 4m 45s wall time 100k peak context
The current docs say stopped runs surface in the in-run assistant pane with title, diagnosis body, and report text, and that they no longer open a full-screen blocking overlay. The assistant follow-up notes mark the old selection defect as spent because the overlay was removed. The archived plan remains available as the historical source for the change, while the live plan queue no longer treats it as pending work.
The final sprint waited until the behavior had landed, then made the written inventory match it. Its scope was documentation and plan bookkeeping: stop overlays should disappear from live modal inventories, assistant-pane docs should describe the transcript entry, and unrelated runtime or engine behavior should stay out of the edit. It completed cleanly, showing the implementation had already settled enough for a factual docs pass.
