• Event log panel — the board's history as a readable feed, docked beside it behind a Log checkbox, folded by day, with commits carried inline and every line marked by kind.
• History playback — the board's past plays as a movie, the player docked as a drawer, with the scrubber standing down while it runs.
• Timeline narrowing — Ticket only scopes the chart to one ticket and the stretch it has lived; Scope only and Ticket only now named alike, and a dragged-out window survives opening a ticket.
• Scope row folds into a select where the bar has no room for it.
• Filter the board by actor, not just assignee.
• Agents take a provider/name identity, announce it, and can assume a board name mid-session.
• Commit diffs — a file's header pins while you scroll, files open the way you left the last one, and diff code sits at the app's own text size.
• Built for scale — a 20-person decade (960k events) now replays in ~1.8s instead of hours; filing a ticket is 0.21s and the read after it 0.29s
• Boards send the tickets a reader is looking at rather than every ticket ever closed — an 88.7 MB payload down to 8.8 MB.
• Timeline derived once per state of the log instead of once per request.
• Fixed: a comment with no author could take the whole board down.
• Fixed: an event was applied to the board under one id and written to the log under another, so log rows could not be matched to the chart or checked out.
• Fixed: TUI descriptions overflowing their box, and line numbers drifting.
• Opt-in stress harness — generates and replays a team's decade of history in a container; never part of any pipeline.
• The GUI can be told which port to bind.
