vim-user-guide.pdf has no NUL bytes, so git auto-detected it as text and
core.autocrlf rewrote its line endings on checkout, corrupting it. Mark
PDF, PNG, PRG, BIN, and D64/D71/D81 files binary so they are never converted.

Nova128 is an object-oriented language with an on-machine C128 compiler.
This adds the spec, decisions, architecture, backlog, and story claims,
plus the grammar fixtures (E00-S02), disk-image builder (E07-S01), and
the x128-verified platform probes:
- E01-S01 minimal native PRG
- E01-S02 MMU/common-RAM probe. With bottom common on, a P0/P1 pointer
aimed at bank 1 lands in bank 0 at the translated page. The verifier
traces every MMU write in the probe window.
- E01-S03 KERNAL wrapper (kcall). CHROUT, drive status, and a
device-not-present failure work from bank 0 and bank 1 mappings.
A/X/Y/C/ST are preserved and the MMU state is restored exactly.
- E01-S04 40/80-column display and clock probe

NOTES records the dd/p, A/I/O/o, :q/:q! and missing-file checks that pass
on the work disk, and that \x03 in -keybuf arrives as RUN/STOP so a script
can leave insert mode.

The single-row painter became vml.s at $C000: one sys() paints all 24
rows, memmove and line-index fix-ups run in ML, and the keyboard buffer
is popped with IRQs masked. dall() repaints only the cursor row or the
whole screen, so j went from 17 to 0-3 jiffies. Loading now checks the
drive error channel and splits lines over 80 columns. The temporary
jiffy counters used to measure the speedup are removed; the numbers are
in NOTES.md.

Power C on the C64 calls ML as sys(addr, &a, &x, &y); the bank argument
from the manual's C128 library page made sys() jump to $000F and crash.
The ML row painter now runs. Quitting resets through $FCE2 because Power C
owns BASIC's zero-page pointers. Notes and Power C skill updated.
