This run turned the terminal monitor's large source modules into directories without changing their intended behaviour. Its milestones established a code-motion check, divided the TUI root, separated rendering by pane, and grouped state by surface.
How this walkthrough is structured
Feature
What did the run build and ship?
The current tree retains the TUI directory roots, pane-owned rendering modules, surface-owned state modules, and the checker that supports later code motion.
Build
How did Gantry structure the work?
The cut used stable module boundaries and a code-motion check to divide the terminal monitor without making a broad behaviour change.
Milestone 1
Motion Proof And Tests
4 tasks 13 agents 1h 29m wall time 177k peak context
The code-motion neutrality checker and its reference documentation are present in the current tree. The TUI tests now live in a subject-based tests directory beside the TUI production modules. Those files retain the verification tool and test layout the milestone required.
The first milestone established the proof instrument before production modules moved. Its brief kept the scope to the checker and subject-based TUI tests, so later extractions had a defined comparison boundary. The ledger records the milestone green, while the run facts do not attribute gate or review events to this milestone.
Milestone 2
Tui Directory Core
6 tasks 20 agents 2h 4m wall time 188k peak context
The current `src/tui/mod.rs` describes a directory organized by role and declares the modules that carry it. Its re-exports still provide the TUI surface used outside the directory. The directory is present, although the available git facts do not isolate every extracted module from later work.
Tui Directory Core isolated the top-level TUI split from the later render and state work. The brief used the existing banner chapters as module boundaries and required the public `tui::` surface to remain available. The ledger marks the milestone green, but the run facts supply no milestone-local account of stress or recovery.
Milestone 3
Render Pane Split
5 tasks 15 agents 1h 31m wall time 126k peak context
The render root imports separate activity, chat, git activity, overlays, pattern, sidebar, stage log, stats panel, and text modules. The current sidebar implementation remains under `src/tui/render/sidebar.rs`, matching the pane-owned layout. The render split is still visible in the tree.
Render Pane Split gave visible panes and overlays their own boundary, leaving shared formatting in a render-local module. That cut let the rendering change be assessed apart from the root and state reorganizations. The ledger records completion, and the run facts do not identify which render work, if any, encountered the recorded gate failures.
Milestone 4
State Surface Split
6 tasks 20 agents 2h 40m wall time 244k peak context
The current state root declares modules for blocker, chat, event, feed, git activity, layout, overlays, pager, pattern, settings, stage log, stats panel, and stop state. The structural-liabilities record identifies the intentionally whole dispatch functions after the TUI directory split. The archived plan also remains in the tree as the record of the closeout.
State Surface Split completed the directory conversion by grouping application-state code with the surfaces it serves. Its brief reserved shared application state, root enums, and dispatch for the state root while moving surface details outward. The ledger is green, and the run facts contain no milestone-local stage attribution for this boundary.
