5# Draws the real widget tree through Metal in this process and writes each frame
6# to a PNG, then compares it against the committed baseline at the runner's
7# stated threshold (99% of pixels). Nothing here synthesizes a system keystroke,
8# so nothing here can type into another application's window by mistake.

10#   script/omega-visual-proof              compare against the baselines
11#   script/omega-visual-proof --update     rewrite the baselines
12#
13# Two processes, not one. The first captures the front door, the typing path and
14# the executor line on three thread kinds, then leaves on disk what a relaunch
15# would find: the correlation journal in its production schema at its production
16# path, plus the thread ids and agent id that `ZED_STATELESS=1` deliberately
17# keeps out of a database. The second process is a genuinely cold one — empty
18# statics, no threads, no panel — and photographs the executor line it derives
19# for a `codex-acp`-class thread and an engine-lane thread from that disk state
20# alone. omega#77 asks for those two "after restart", and a second phase of the
21# same process could not answer it.
22#
23# Baselines live in crates/zed/test_fixtures/visual_tests/ and were generated on
24# Apple Silicon with the Metal renderer. A materially different GPU may need
25# --update and a human looking at the result before the new baselines are
26# trusted.
