ConsoleView

Remarks

Doc 20 calls the Console "the least built thing in the shell" and the largest single item in its Part A, and both were true: it was a TextBlock saying "Nothing logged yet." What replaces it is doc 20's A7 in full — a virtualised list over the ring the diagnostics layer already keeps, level toggles carrying counts, a category filter, a search box, collapse-duplicates, clear, clear-on-play, and a detail pane showing the whole record and its stack.

⚠ It does not allocate per line. Doc 20 is blunt about why — "a game logging per frame into a panel that keeps strings is a leak with a UI" — and there are two halves to it. ConsoleModel pulls only what is new out of the ring and keeps indices rather than text; VirtualizingPanel keeps about thirty row elements whatever the list holds. A hundred thousand lines is a hundred thousand records the sink had already allocated, and thirty elements.

⚠ Rows are rebuilt from the model on Tick, not from an event. The sink is written from every thread the editor runs work on — a content import logs from the pool — so a subscription would rebuild the panel from a background thread. One pull per frame on the thread that owns the document is the same bargain ContentTasks makes.

⚠ Selecting a row is not the same as it staying selected. The list scrolls as records arrive, and the detail pane is holding a record rather than a row index — so a line selected and then pushed off the top by a burst still has its stack on screen.
