A deep-dive panel for a run's stats and git history

This sprint moved existing pager keys into the action registry before any new reader behavior was added. That was a small enough task for one agent because it preserved current scrolling and closing semantics while introducing only the overlay scoping the registry needed. Its review led to a re-plan of later pager work, so the boundary exposed a real dependency issue early without producing a red gate.

Search was layered after registry integration so its keys could join the same scoped surface instead of extending the old inline dispatch. The brief also had to stabilize an upstream menu-crate change that the prior sprint had left outside Gantry's managed worktree. Review again re-planned the remaining pager work, which is consistent with this sprint turning the pager from a scroller into an interactive reader.

This sprint was a rendering cut: long-line presentation, horizontal offset, and key registration, without changing where pager content came from. Search already existed, so the agent had to keep line addressing stable across both wrapped and unwrapped views. The run record shows a clean boundary here after the preceding re-plan settled the shape.

Follow mode required the pager to know whether its text came from a file, so the sprint was scoped around source threading and refresh behavior. That made the task larger than a key binding but still local: generated views kept no source, while file-backed views could be reread. It passed without recorded repair, leaving the next sprint with filename context for classification.

The last pager sprint took the source information from follow mode and added cheap content and filename heuristics. Its brief kept the work bounded by rejecting a highlighting engine or parser-heavy design. With search, wrap, and follow already present, the sprint's main boundary was preserving line identity while a single JSON record could expand in place.

The first stats sprint deliberately carried no UI. Its job was to extend the existing fold over run events with the data the panel would later read, including absent-versus-zero token handling and separate park or retry buckets. That made the correctness burden testable in one place before any modal code depended on it.

This sprint turned the data layer into an overlay while keeping the visible scope to the timeline and shared bar helper. The cut was fit for one agent because modal state, input precedence, collapse behavior, and timeline rendering were all one TUI surface. It depended on the stats projection already being exact, so the panel did not need to rescan history.

After the modal shell existed, this sprint was intentionally a rendering pass. It filled the remaining panel sections from the already-extended projection and reused the same proportional bar helper. With no new interaction model or stats model promised, the boundary stayed narrow and the gate remained green.

The final stats sprint connected panel rows back to artifacts and expanded the demo run so the surface could be smoked manually. Its scope was the boundary between a selected stats row and the shared pager, not a new stats calculation. That was possible because the panel already had navigable rows and the pager already had file-backed reading behavior.

The first git sprint isolated correctness in a parser and runner before any view existed. The brief asked the agent to derive the commit range, attribute commits from ledgers, and make unreadable worktrees a data outcome rather than an exception. The run facts show this unit started more than once after surrounding support trouble, but its own recorded stages completed green.

With the data layer in place, this sprint was overlay plumbing and background loading. The agent could mirror the stats panel's surface shape while adding the channel handoff needed to keep git calls off the render thread. Its boundary ended at a navigable list, leaving diffstat and patch behavior for the next sprint.

The last git sprint completed the interaction path from commit row to diffstat to full patch. It reused the existing off-thread git plumbing and the shared pager, so the sprint did not need a second diff renderer. The demo requirement stayed scoped to mock engine metadata, keeping real run behavior unchanged.
