The build/ pattern matched every directory of that name, not just our
build output at the root -- so vendor/libghostty-vt/src/build/ (the
library's own build.zig helpers) never made it into git, and make
vendor broke on fresh clones. Anchor the ignore to /build/ and restore
the 284 files it had silently dropped.
sl0ptty: M0 — libghostty-vt vendored, one pane, compositor, diff renderer2026-08-13T20:00:03Zsl0psl0p@sl0p.foo2026-08-13T20:00:03Zurn:sha1:2c1b855c3cf8cf8841bf25cd939e478a7f0bfac8
Design contract in DESIGN.md. libghostty-vt vendored fresh from ghostty
main@bedb6f2 (zig 0.16), built to a 14MB static lib.
M0: pty spawn (no libutil), a lib-vt terminal per pane, a screen cell buffer,
a diff emitter that repaints only what changed, raw mode, SIGWINCH, and a
~120Hz frame cap that coalesces pty reads.
Also the seed of the headless harness: --headless dumps the composited screen
without a tty, so composition is testable in milliseconds.
tests/live_m0.py covers what headless cannot: raw mode, the diff emitter,
resize propagation, and the quit path. 6/6 green.
