Twenty-one new headless tests covering the GPU-side acceptance items of
docs/gpu-set-font-framing.md (9-14, 16-19):
- 9: size route re-derives metrics; (None, None) reset reproduces
the never-set frame byte-for-byte
- 10: 600/7200 bounds render; minibuffer dropdown windows its rows
above the band at the derived row height; context menu keeps
the clipped route with coherent hit geometry
- 11: wrapped caret survives 16->72->6 px; an optimistic insertion
that wraps a new bottom row follows immediately and its
confirming CursorByte needs no second repair; overscan caret
never snaps the viewport; narrowing resize re-follows via the
coarse + visual-run + fold pipeline; adornment projection
shifts the caret past injected text with left gravity at the
anchor; the CursorByte arm follows into a wrapped run as a
normalized sub-line residual; explicit scrolls clear the
residual (including wheel-up at the clamp edge); the
minibuffer suspends the follow decision
- 4 (GPU half): BufferSnapshot resets the residual while the font
preference/metrics survive -- the replacement buffer wraps
too, so the EOF clamp cannot mask a leaked residual
- 12: unknown + proportional families fall back; the four-style
gate rejects a proportional BOLD sibling the normal-only
query would accept; a valid second monospace family resolves,
changes the ink, and resets cleanly; the parameterized
sanitizer removes exactly the same-family proportional
collision
- 13: the "\0" sentinel defeats the status string-equality gates
- 14: a shrinking visible slice re-declares the scoped viewport
- 16: 0/599/7201/u32::MAX reject the whole message, state untouched
- 17: metrics + drawable dimensions atomic on all seven buffers,
resize symmetric via Buffer::size()
- 18: popup rows never wrap (Wrap::None + unique line_i per run)
- 19: with line numbers and a context menu open over an EMPTY
buffer, the measured probe advance drives gutter reservation
and menu hit width (fixture ratio exactly 1.2 vs the bundled
default); reset restores the exact geometry and frame
Family routing is hermetic: four generated fixture faces under
pmacs-gpu/fonts/test/ (second monospace at 720/1000, a proportional,
and a "Pmacs Test Family" whose NORMAL face is monospaced but whose
BOLD face is proportional), built by the committed generate.py --
provenance and license in LICENSE.txt beside them. fontdb requires a
PostScript name (nameID 6), which the generator sets explicitly.
assemble() now routes construction through sync_buffer_dimensions
too: shape_until_cursor and wrapping must use the painter's clip
from the first frame -- a v16 daemon never sends the FontFacts that
would sync them later (found by the CursorByte-follow test: the
caret parked in the status band at surface-height dims).
Every protection was bitten (temporarily reverted, its test observed
failing, then restored): wire validation, CursorByte visual-run
follow, painted-before gate, projection inversion, Wrap::None,
four-style gate, sanitizer, status sentinel, normalize fold,
scroll_by_lines residual clear, BufferSnapshot residual reset, the
all-seven dimension helper, and the optimistic-completion follow.
The snapshot-reset test was strengthened after its first bite did
NOT fail (a short replacement buffer let cosmic's EOF clamp zero the
residual anyway).
PMACS_REQUIRE_GPU suite 90/90; clippy -D warnings and fmt clean.
