# RULES

- Never mention the user's emotional state. I'm here to work, NOT be psychoanalyzed by a machine.

+ # TUI TERMINAL KNOWLEDGE (verified, don't re-derive)

+ - ANSI emulator resize semantics ARE the product: alternate-screen buffers

+ must resize like pyte/real terminals (truncate columns on width shrink,

+ top-trim/pad on height change, 1:1 grid rows <-> buffer lines, clamp

+ cursor) — folding stale wide lines breaks CUP row addressing = garble.

+ Scrollback (normal) screen keeps folding. Oracle test: pyte dev dep.

+ - Two terminal pathways by mandate: `tui/agent_terminal.py::AgentTerminal`

+ (headless PTY + raw byte capture) backs the ACP terminal tool; the

+ human-facing emulator (TerminalTool/EditorTerminal) is separate. A

+ suspended conversation has window size 0 — never size a PTY from it.

+ - Textual gotchas: `Widget.screen` is a Textual property (name pyte

+ screens `pyte_screen`); `Strip` API is cell-based in Textual 8

+ (`crop_extend(0, w, None)`, `adjust_cell_length`); Textual 8.2.x breaks

+ on rich>=15 (uses Style internals rich dropped) — pin rich<15.

+ - pyte color values are "default", ANSI names, or 6-char hex strings for

+ BOTH 256-color and truecolor — never numeric palette indices (an

+ all-digit hex like "281733" is truecolor).

+ - A TUI only sends DIFFS: any fresh out-of-process terminal client

+ (riotermjs, reconnect) sees a blank/stale screen unless the child is

+ forced to full-repaint (winsize nudge: set cols-1 then cols).

+ - sandbox/textual-term-toy: the terminal-in-a-column experiment + the

+ riotermjs browser harness (bridge.py = PTY<->websocket; harness/ = page

+ with importmap to ~/src/riotermjs dist). How to view the TUI in a

+ browser: run bridge.py + `python -m http.server --directory harness`,

+ open the page, screenshot via playwright-cli.
