vega/surfaces/screen.c, branch masterSurface runtime projecting Pure views across pixel, terminal, CLI, and web.

vega_text reads an i64 view or column as an integer and prints all of
its digits, so an ID past 2^53 shows as it is on the CLI, the TUI,
speech and the web surface, where a number would round.
Show a bool as true or false, and make the examples' flags bools2026-09-30T14:29:20Zeunhhunecpition205@gmail.com2026-09-30T14:29:20Zurn:sha1:72ecae6b6eb1365e722bd6d45acae8a5ccb74b23
aup and Pure now have a bool (Pure 016): a view or column may be one.
vega_text writes it as true or false, as a string's interpolation does, so
every surface shows the same words: the CLI, the TUI's cells, speech and
the web surface's JSON (a value's text) and page. An app that wants other
words picks them with a conditional (if t.done { "done" } else { "" }).
The flags of the examples are bools: todo's done and urgent, today's done,
the stopwatch's running. vega.when takes the bool as it took the number.
bools checks a bool field and a bool column on the CLI, the TUI, speech
and the web surface: true and false, never 1 and 0.
Wait for timers on the monotonic clock; events still see the wall clock2026-09-29T17:12:23Zeunhhunecpition205@gmail.com2026-09-29T17:12:23Zurn:sha1:c919b5f81ad6cad55935fa7a22bfda9539dd584f
The terminal, the pixel surfaces and the web page reckoned when a timer
was due on the wall clock: set back, a timer waited until the clock came
again to the tick it had waited for (Pure's review 004). vega_clock is
the monotonic clock; timers are due on it, and a tick sets the time its
event sees from the wall clock (vega_now), as before.
check.py's clock_set_back runs a timer of 20 ms in the terminal with the
wall clock set back an hour 0.2 s in (Pure's build/clock-back.so, an
LD_PRELOAD of clock_gettime): 40 ticks in 0.8 s, where Vega before this
stops at 9. make check passes it --clock-back.
Name Vega's parts: lib/, surfaces/ and symbols/2026-09-27T12:45:31Zeunhhunecpition205@gmail.com2026-09-27T12:45:31Zurn:sha1:2920e389f624263efe515d9a5f33f6b822efff5e
src/ held two parts, the surfaces that show modules to people and the
symbol format with its CPU and GPU drawing. As in Pure (design 009), top
level directories are now the parts, and the README says what each builds.
