Robert Allan JamesandClaude Sonnet 5 859381640b FABRIC.md: insert 4.4e/4.4f/4.4g (found verifying 4.4c/4.4d), renumber 4.4e-4.4p to 4.4h-4.4s ...

4.4c/4.4d's fix was screendump-verified on amd64: the framebuffer console
mechanism works and [VMName] genuinely reaches the screen for the first
time. Verifying that screendump surfaced three more issues, each given its
own item per SS25.0 rule 3 rather than folded in silently:

- 4.4e (fixed this session, see prior commit): console_putc() forwarded raw
  '\n' to vt100_putc() without '\r', corrupting line-start columns.
- 4.4f (open, not root-caused): character glyphs render vertically flipped.
- 4.4g (open, not root-caused): most of the framebuffer stays blank despite
  hundreds of lines of boot output that should have scrolled through it.

Confirmed via a second screendump after the 4.4e fix that 4.4f and 4.4g are
both independent of the \r/\n bug -- unchanged before and after.

Added evidence/ as a new tracked location for durable proof screenshots,
distinct from the existing gitignored fb/ (disposable local eyeballing,
per the 2026-08-07 decision to stop tracking it). Linked from the relevant
4.4c/4.4d/4.4e/4.4f/4.4g entries.

4.4c and 4.4d remain unchecked -- their Done-when criteria require a
three-arch screendump match against the serial log, not yet attempted on
aarch64/riscv64.
