full-screen vt100 terminal 4.4v -- keyboard-to-REPL bridge, real and tested: Refactored KEY-EVENT's per-arch translation logic (keyboard_words.c) into a shared C function, sk_key_event_poll(), so the REPL bridge reuses item 4.3.5f's already-converged Linux-keycode-namespace event stream instead of building separate amd64/aarch64/riscv64 tables. repl.c's sk_kbd_getc() decodes the standard US-QWERTY printable range plus Enter/Backspace/Shift against that stream; sk_readline() polls it as a second source alongside console_getc(). Verified via QEMU monitor sendkey injection, and by Captain Bob typing directly into the live QEMU window over real emulated PS/2 hardware mid-session (1 1 + . -> 2 ok, then a clean BYE shutdown). 4.4ab -- simplify to a full-screen terminal: Captain Bob's call, reverting the 640x480 CANVAS box + independent REPL strip (4.4o/4.4t/4.4x/4.4z) in favor of the simplest shape: the entire framebuffer is one vt100 terminal, g_vt.cols/rows = fb_width()/fb_height() divided by cell size, no origin offset, no box, no strip, no border drawing. The REPL prompt is just the terminal's last scrolling line. Scrollback, TTF rendering, and SGR color are all box-agnostic and keep working unmodified. 4.4r -- reframed as a text/graphics mode toggle: "Hide/show the scroll box" stopped meaning anything once the box was removed; the underlying need survives as a whole-screen mode switch. vt100_toggle_graphics() is a two-state machine (VISIBLE/HIDDEN) -- hidden mode stops the terminal from touching the framebuffer while its logical state keeps advancing, so direct framebuffer/TTF-TEXT drawing can use the whole screen; showing again wipes and reuses scrollback_redraw() to restore the terminal exactly. Reachable two ways, one transition function: physically via Alt+TAB (4.4y revised from Ctrl+TAB) and programmatically via the new ALT+TAB FORTH word. Verified: three-arch clean QEMU boot + logs; amd64 screendump confirms full-width text with no box/strip artifacts. Punch list §25 items 4.4v/4.4r/4.4ab complete; 4.4y revised.
