- New L1 crate filmcraft-text: fonts (bundled Inter Regular/Medium/SemiBold/Bold/Italic,
JetBrains Mono, Noto Serif; DirectorySource scans system font folders reading only name/OS2
tables; family/style resolution with synthetic bold/italic; per-char fallback), layout
(harfrust kerning/ligatures, unicode-bidi, unicode-linebreak, alignment incl. justify,
leading, tracking, baseline shift, all/small caps, underline, carets/hit-test/selection,
cached), raster (moved from captions; active-edge list, shapes, emboldening), render
(outline + sub-pixel glyph-mask caches; transformed-outline path for rotation/skew),
mask (distance-transform strokes, blur).
- Captions burn-in now shapes and kerns via the engine (font.rs/raster.rs removed).
- Timecode / Clip Name effects draw real text (full clip names, not seven-segment digits);
text_burnin golden re-blessed.
- UI takes its font bytes from the text crate (no duplicate copies in the binary).
- New fonts: Inter Bold, Inter Italic (OFL-1.1, rsms/inter v4.1), Noto Serif Regular
(OFL-1.1, notofonts) with sidecars, ATTRIBUTION.md rows and licence text.
- Perf: 3-line 96 px title at 1080p ~1.6 ms cold / 0.15 ms warm (release).

crates/golden (test-only, L3): nine procedural 320x180 scenes (transform
and opacity, blend modes, Gaussian Blur, Lumetri basic, Crop, Cross
Dissolve / Dip to Black / Wipe mid-transition, timecode/clip-name text)
rendered on the CPU and compared with committed goldens (PSNR >= 45 dB,
max <= 12, p99 <= 2); FILMCRAFT_BLESS=1 regenerates them with
attribution sidecars. testkit::golden adds PNG I/O, diff metrics and
failure images. The same scenes are composited on the GPU and compared
with the CPU.
GPU parity exposed a real bug: GpuCompositor cached uploads by
pixel-buffer address without owning the buffer, so a new frame
allocated at a freed frame's address was drawn with a stale texture
(whole wrong frames, PSNR ~12 dB). The cache now keeps the buffer
alive; regression test upload_cache_keeps_buffers_alive.

New dev-dependency-only crate crates/testkit (L0, no FilmCraft deps):
FILMCRAFT_FFMPEG/FILMCRAFT_FFPROBE, then PATH (incl. .exe), then known
dirs; SKIPPED lines and FILMCRAFT_REQUIRE_ORACLES=1 to make skips fail;
require_ffmpeg!/require_ffprobe!/require_oracles!; fixtures_dir() under
<workspace>/target/fixtures with per-thread temp names and atomic
generation. Oracle helpers in aac, opus, h264, hevc, h264enc, isobmff,
matroska, prores and export migrated (codecs left on its local lookup).

Public equivalents of the maintainer-local plan/: docs/architecture.md (layers as enforced by
xtask, Tick time base, data model, command system and undo, render/playback/export pipeline,
automation surfaces), docs/contributing.md (+ root CONTRIBUTING.md), docs/testing.md and
docs/agents.md (MCP/control channel usage, agent work loop, decision rules, Definition of Done).
CLAUDE.md points at the public docs wherever it references plan/; AGENTS.md gains a See also list;
README gains a Documentation section.
