- api-reference: the new `displayModel` session field, its sources in order
(custom-endpoint, statusline, screen, launch) and that it is untrusted
display text, persisted and restored when the CLI reported it.
- cli-registry: `capabilities.modelDetect` (one capture group, the last rows
of the probe's capture, anchored on chrome only that CLI draws), the two
stock patterns (dsh-TUI, codex) and the fifth config regex.
- architecture-invariants (tile grid): the header painter, the id as data, the
untrusted model text, no writes for an unchanged session, the truncation
order, Pane A's strip and its fits through syncTerminalGeometry.
- tile-grid-plan "as built", the wiki's Tile Grid page (logo and model rows,
Split's strips), and CLAUDE.md's tile grid and CLI registry paragraphs.
