tai/taicpp/docs/tui.md

tui parity (tai.py -> taicpp, src/tui)

Scope: every Tui* class and tui_* function of tai.py (framework, VT screen, widgets, themes, chat scene, live block, keys, mouse) and every Grr* class and grr_* function (the grr terminal client). Specs the code follows: ../tui.md, ../grrtui.md (tables copied into tests, see below). The grr client is a client of the grr server: it shows what /api/spec and /locales.json say, no server string, color or limit is copied into the code (GrrConst.h holds only what tai.py itself carries as fallback).

Rules of the port

• Python class TuiFoo is C++ class detz::tui::TuiFoo in TuiFoo.h / TuiFoo.cpp. Small related classes share a file pair and are named in its header comment.
• Module functions become static methods of the class that owns the data (tui_resolve_theme_name is TuiThemes::resolve_name, tui_demo is TuiDemo::demo).
• Module constants become constexpr or static functions; names are kept where C++ allows.
• Text is UStr (std::u32string) so column math is by code point like python. TuiValue is the dynamic JSON-like value (python dict/list/str/float formatting).
• No behaviour was invented: where python has a quirk the port has the same quirk.

Declared differences (all invisible on screen)

python	C++	why
__setattr__ change signals (TuiObserved, TuiList, TuiDict, TuiSet)	explicit setters call relayout, restack or touch	C++ has no attribute hook. A field written without its setter does not repaint; every field python watches has a setter
per-style cell pools (TuiCellPool)	cells are (char32_t, interned style id)	perf only, equal cells still compare by two integers
asyncio loop	one poll() loop with a self-pipe wake, timers and offload threads	same ordering contract: offload work runs on a thread, done(result, error) on the loop
TuiTerminal row memo	not kept	perf only
python exceptions in offload	std::exception_ptr, text through TuiApp::describe	same message as str(exc)
http.client (GrrClient, GrrStream)	libcurl	the repo already links libcurl; error texts for transport failures are mapped by hand (see gaps)
agent / store / vault used by the local chat scene	interfaces TuiChatAgent, TuiChatHost, TuiHistoryBackend, TuiComplete::Sources	the agent module is another port; the integrator writes the adapters (wiring/tui.md)
GrrControl threads	one accept thread, one thread per connection, jobs run on the UI loop	same protocol, same caps

Verification (what was run, not what is believed)

All differential runs compare the C++ binary with tai.py on the same input.

what	how	result
--demo-shot frame	text, per-cell sgr and raw frame bytes at 30x100, 24x80, 10x30, 50x160, 8x20	identical
framework scripts	9 scenarios (keys, mouse, prompt and autocomplete, resize, spawn, shell feed, paste, kitty keys) at 30x100 and 12x40	identical
chat rows, markdown, textwrap	3318 cases, 65553 output lines, every span as <sgr>text	identical
local chat scene	10 scenarios (send, commands, keys, bots, resize, history, completion, scroll, multiline, quit) at 30x100 and 14x50, a fake agent on both sides	identical
grr client against a real grr server	both binaries on a pty, driven by the control socket (screen, key, type, click, goto), server restored from one snapshot before each run	see below
grr spec drift	tests/tui_spec.cpp (routes, keys, caps, shapes, events, flags against grrtui.md)	ok

Grr runs (screen text of every step plus per-cell fg, bg and attributes of the pty stream replayed through python's TuiVtScreen, minute digits ignored):

steps	size	text diffs	style diffs
57 (every bot, computer, screen, chat route)	30x100	0	0
128 (keys, mouse, dialogs, settings, language, composer)	30x100, 24x80, 14x50	0	0
128	40x160	1 (spinner frame)	2 steps (spinner frame)
51 (pane tabs, composer, send, remote terminal)	30x100	0	0
14 login screen, 14 offline screen	30x100	0	0

The only differences ever seen were a wall clock, the database size shown in Advanced, a chat title that the server generates after the fact, a spinner frame, and ids the server creates. Each was traced to the environment, none to the port.

Symbol table

344 python symbols (classes, tui_* / grr_* functions, TUI_* / GRR_* constants) and where they live. Generated by matching names against src/tui; a hit means the name is defined or used there, not that the behaviour is proven (that is the section above).

Gaps (not verified, listed next to what would close them)

• Paths with no differential run: approval cards and question cards answered by a bot, live process cards (GrrProcessItem stream, transcript replay, Type and Expand), file and files messages, the file viewer, the Preview and Files pane against a bot that has files, template sharing. They compile, and the screens that open them match, but need a bot that produces them (a real model call). Closing it: tests/grr_tui.py equivalent driven against the C++ binary.
• The remote terminal (GrrRemoteTerminal) was driven against a bot computer that was not running on the test server for the echo step: the typed text never reached a shell. The two screens matched while it showed the prompt; typing into a live shell and the resize path are not verified.
• Local chat scene threads: the offload, reveal and prompter paths run on the loop in the tests with a fake agent. A real agent adapter is not written here.
• Transport error text: GrrClient::offline_reason maps libcurl results to python's wording for timeout, unresolvable host, empty reply and OS errors (refused matched python on the offline screen). Other curl errors show curl's own text.
• GrrTimezoneView reads /usr/share/zoneinfo (python: zoneinfo.available_timezones()); verified equal on this machine (486 zones), not on a machine with tzdata from pip.
• GrrFormat, GrrText, GrrStrings, GrrRouter::parse and GrrPalette have no direct unit diff; they are covered through the screens above.
• Opening a link or file spawns the desktop opener and does not reap it (same as python, which leaves the child to init).
