- clip.audioGain takes mode set|adjust|normalizeMax|normalizeAll (the
old {db, relative} form still works); peaks are measured on the
clips' source ranges. Normalize Max Peak applies one adjustment so the
loudest clip lands on the target; Normalize All Peaks sets each clip.
- clip.audioPeak reports the selection's peak amplitude (with gain).
- Clip > Audio Gain... (G) opens the dialog with the four options, dB
fields and the peak amplitude; automation ids audioGain.*.
- effects.setDefaultTransition sets the default video or audio
transition (Constant Power / Constant Gain / Exponential Fade) that
sequence.applyAudioTransition (Cmd+Shift+D) uses.
- tests: gain modes and peaks, dialog by automation id, transition
curves (power / amplitude preservation, end points).

- Audio Track Mixer: strips for audio tracks, submixes and the Mix with
effect/send slots (disclosure), input mapping, output assignment, pan
knob, automation mode, M/S/R (solo safe on submixes), fader with dB
scale and our own taper, stereo meters fed by the playing mix, value
hot text, footer transport; horizontal/vertical scrolling. Fader and
knob drags are mixer.touch while held and mixer.release on let go, so
they are heard live and recorded in Latch/Touch/Write.
- Audio Clip Mixer: per-track strips for the clip under the playhead
(clip Volume / Panner, write-keyframes toggle), clipMixer.set with one
undo step per drag (Session::edit_merged).
- Timeline: per-track "Show Keyframes" button picks clip keyframes or a
track lane (volume, panner, mute, sends, insert params); the lane is
drawn across the track, Pen / Cmd-click adds, diamonds drag in time and
value, right-click deletes.
- Playback starts an automation pass and stopping writes it; the audio
callback reads the newest project snapshot (LiveMix), so mixer moves
are heard while playing. Audio Meters read the graph's live meters
instead of re-mixing at the playhead.
- Automation ids on every control; headless kittest tests drive the
panels by id and by multi-frame drags (FILMCRAFT_UI_SNAPSHOT_DIR renders
offscreen PNGs through wgpu).

- filmcraft_media::cancel: a per-job cancellation flag passed through a thread-local, so the
MediaSource API is unchanged. Frame workers run each job inside it.
- FrameServer::retain_queue (called by schedule_playback every refresh) now also cancels running
jobs for frames the playhead has passed. Before, a worker blocked on a source's decoder lock
went on to decode its frame after playback had moved 50–100 frames on, found it evicted and
restarted the decoder at the keyframe (decoder trace: "seek i=32 key=0 next=142").
- GopCache gives up (CodecError/MediaError::Cancelled) before seeking or decoding for a cancelled
job and between samples; decoder state stays consistent, so the next request carries on.
- The CPU compositor checks the flag between tracks and effects; cancelled results are never
cached.
- Stop drops queued prefetch jobs and cancels running ones (FrameServer::stop_prefetch). They
used to run to completion after Stop, e.g. 14 frames of live effects rendering competing with
a Render In to Out started right after.

- project: ItemKind::Graphic (transparent canvas source, hidden from the Project panel,
unlimited duration); graphic layers are hidden effect instances graphic_text /
graphic_shape on the clip (serde for free, keyframes on every animatable property,
Source Text holds), with appearance (fill, two strokes outer/centre/inner, background
box with radius, drop shadow) and transform (position, anchor, scale, rotation,
opacity); eval_layer gives a plain LayerSpec. No schema migration: all additive.
- render: graphic_clip rasterises each layer straight to the output transform (crisp at
any Motion scale/rotation), caches layer rasters, composes a tight image for the GPU
plan; standard effects on a graphic run at source resolution first.
- engine: graphics.newText (Cmd+T) / newShape (new clip above the footage at the playhead
or a layer in an existing clip), setText (typing coalesces into one undo step), set,
selectLayer, deleteLayer, arrangeLayer, align (frame / selection), distribute,
graphics.list, fonts.list. EditorState.graphic_layers holds the layer selection.
- goldens: graphic_title, graphic_shapes (CPU and GPU parity).

- project: MixerStrip on every audio track, submix tracks and the Mix
(automation mode Off/Read/Latch/Touch/Write, lanes for volume/pan/mute/
send levels, effect-parameter automation in the insert's own keyframes,
sends pre/post fader, output routing, record arm, solo safe, input map);
pre/post-fader flag on inserts; serde defaults (no schema migration).
- render: mixer graph (tracks -> submixes -> Mix) in Premiere's order:
pre-fader inserts, pre-fader sends, mute, fader, meter, post-fader
inserts, post-fader sends, pan/balance. Per-sample automation, effect
params on an absolute 64-sample grid (output independent of request
cutting), route-level latency compensation, cached continuation state
with pre-roll, solo/solo-safe logic, -3 dB constant-power pan law for
mono tracks, balance for stereo. LiveMix carries held controls (Touch
ramps back over the automatch time), meters and the newest project.
- engine: mixer.* commands (setStrip, setValue, touch/release,
recordStart/recordStop, submixes, inserts, sends, track keyframes,
writeAutomation, inspect) and the automation recorder (gesture streams
thinned into keyframes, one undo step per pass, Switch to Touch after
Write); Preferences > Audio (automatch time, keyframe thinning).
- tests: gain/pan law, block-boundary automation, solo/mute/solo-safe,
sends, latency alignment, render-vs-playback identity, recorder modes,
perf (24 tracks x EQ+Dynamics+Reverb + submix: 6.3x realtime, one core).

- 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).
