- mxf: read_pcm bounds a request by the sample frames the file actually stores (plus 16M
samples of zero padding) instead of a fixed 16,777,216-sample cap, so whole-clip reads of
long stereo MXF (transcription) work again; PCM/AES3 chunk buffers are clamped to the source
length instead of a 256 MiB cap; decode_pcm's output is bounded by its input, so its
fixed cap goes (the AES3 >8-channel refusal stays; a request is also bounded by the source
length divided by the channel count). read_sample keeps only the source-length bound.
- mxf: index_entries no longer fails open() past 1,048,576 entries (the sparse BTreeMap
already bounds memory by real entries); long recordings open.
- project/format: new Sequence/Track/CaptionTrack::check_bounds() hold only the hostile-value
bounds (settings, marks, overflowing time ranges); project load and export ranges use it, so
projects that break only structural rules (overlap, zero duration) still open and export.
check() = check_bounds() + the structural rules, as before.
- project: frame-size cap raised to 268,435,456 pixels, 32768 per side (16K, 16384x8192).
- engine: checked_u32_p accepts integer-valued floats (1920.0); renderable_sequence returns
an EngineError (new Session::try_render_program_at, used by automation render) instead of
eprintln.

Premiere Pro 26.5.2 reopens a project with the same sequence tabs, in the
same order, the same one shown, each at the zoom it was left at. FilmCraft
opened every project on its first sequence; the "Restore open sequences when
opening projects" preference existed and nothing read it.
A saved project file now has a `view` beside `project`: the open sequences in
tab order, the active one, and each sequence's view from NEST12. It is not
part of the project: no undo step, no "edited" mark, and no schema bump (older
builds ignore it). `file.open` restores it when the preference is on.
Nothing in the view is trusted. Ids that are not sequences of the project and
repeats are dropped, numbers are clamped, and a view that cannot be read is
ignored instead of failing the open. A view with no open sequence leaves the
project on its first sequence, so a project saved by a script or the CLI does
not open on an empty Timeline.
Opening or recovering a project now tells the frontend which sequence is
shown, so the Timeline takes that sequence's view.

Problem: a Final Cut 7 XML whose Basic Motion filter sets only `scale`
makes the importer add the Motion effect with its defaults, where
`position` and `anchor` are the NaN "auto" sentinel. Placing a clip
resolves those with `resolve_auto_points`; the interchange import did
not (any format: the clips are built with the effect defaults).
serde_json writes NaN as `null`, and the reader then refused the file:
"project file is damaged: invalid type: null, expected f64". The project
could be saved but never opened again.
Solution:
- project: a point parameter's value (`ParamValue::Vec2`) reads a `null`
coordinate back as NaN, so "auto" survives a save. Only there: `Vec2`
itself is unchanged, and a `null` in a mask vertex or any other point
is still a damaged file.
- project: `Project::resolve_placed_auto_points` resolves the points of
the clips in chosen sequences. Points measured in the frame use the
sequence size. `anchor` is measured in the clip's source
(`Project::source_size`, a subclip through its parent, as the renderer
resolves it) and is resolved only for sources the caller says have
their final size.
- engine: the import resolves in the edits it already makes, so the undo
steps are what they were. In "Import ...": everything but the anchors
of file media, whose size is only what the document says so far (an
EDL says nothing and the importer assumes the sequence size). In each
"Link Media": the anchors of that file's clips, from the probed size.
A clip whose file is not found keeps an "auto" anchor, which the
renderer centres in whatever size the media has, as before this
change.
- engine: a later Link Media (relink.rs `apply`, behind `media.relink`
and `media.autoRelink`) resolves those waiting anchors in its own undo
step, when it has read the file. Nothing else resolves them: a file
that merely comes back at its old path, or a forced relink that does
not read the file, leaves the anchor "auto" (still rendered centred).
Why no schema step and no repair on load: the file's shape is not
changed. Files with `null` points were written by every build before
this one, at the current schema version, so a migration (keyed on the
version) cannot select them, and a bump would only make every new
project unreadable to those builds. They open now and their points are
"auto", exactly as in the session that wrote them; resolving them on
load would mean guessing the size of media that was never linked.
docs/project-files.md describes `null` points.
Tests: project
`point_params_keep_auto_through_json_and_no_other_point_reads_null` and
`placed_auto_points_resolve_once_the_source_size_is_final`; format
`auto_points_written_as_null_open_again`; engine
(interchange_auto_points_tests.rs): import with the media missing, save,
reopen, undo, redo; a linked file whose real size differs from the
declared and the sequence size (undo of Link Media and of the import,
redo); an EDL clip smaller than its sequence; import with the media
missing, save, reopen, relink (anchor becomes a number, undo, redo, a
second relink leaves it). All fail without the change.

aac, bitstream, cfb, color, format, frame, geom, isobmff, media, scopes, speech, the desktop
app and the web app have no production unwrap/expect/panic/unreachable (the web app's two
`expect`s — frame-cache eviction and chunked file reads — become `let … else`); each now
carries `#![deny(clippy::unwrap_used, …)]` outside tests so it stays that way.

- crates/speech (L2): Transcriber trait, FixedTranscriber, Whisper model catalogue (pinned,
SHA-256 verified) with optional downloader (feature `download`: ureq + rustls + RustCrypto),
pure-Rust Whisper inference on candle with word timestamps (feature `whisper`), log-mel, VAD
word tightening, MFCC speaker clustering. Both features off by default and for wasm.
- project: per-media-item transcripts (Project::transcripts); schema v9 with a no-op v8->v9
migration and a v8 fixture.
- edit::transcript: sequence transcript derived from clip transcripts, search, paragraphs,
word ranges, pause/filler detection, ripple delete of many ranges, caption layout.
- engine: transcript.* commands (generate, set, delete, inspect, search, select, extract, lift,
renameSpeaker, removeFillers, removePauses, createCaptions, models, downloadModel);
Session::transcriber for hosts/tests; features `whisper` / `speech-download` (also on the
desktop and CLI apps). Without whisper, transcript.generate fails with a clear error.
- ui: Text panel Transcript tab (Transcribe button, speaker paragraphs of clickable words,
Shift+click selection -> In/Out, extract/lift/remove fillers/create captions, search) with
text.transcript.* automation ids; headless UI test.
- docs/transcripts.md, crates/speech/README.md, architecture and project-files updates.
whisper-tiny measures 12.2% WER over 797 words on local samples.

- filmcraft-media: ByteReader/ReaderOpener (open containers without reading the whole
file) and the pending flag for asynchronous (web Blob) reads.
- filmcraft-codecs: MP4/MOV and Matroska open from a ByteReader; registry of reader
openers (platform sources first).
- filmcraft-engine: Services::reader / export_in_memory; streamed imports; media pool
never caches a still-loading file as offline; Session::pump_jobs advances stepped
exports on hosts without threads.
- filmcraft-export: Exporter (one batch per step, re-renders on pending reads) used by
export(); OutputSink for in-memory output.
- filmcraft-ui-egui: FrameServer::pump (time-budgeted cooperative frame jobs on wasm,
retries jobs whose media is loading); screenshots as base64 on wasm; web-time.

- New crate filmcraft-format (L3): files are an envelope {format, schema_version, generator,
project}; a chain of single-step JSON migrations (v1 bare Project → v2 envelope) upgrades old
files on load; newer-than-supported files are refused with a clear "update FilmCraft" error;
damaged/foreign files report as such.
- atomic_write: temp file in the same dir + fsync + rename + dir fsync; used for every project
write (FsServices), so a crash mid-save never corrupts the project.
- Engine: file.save/saveAs/open go through the format crate; new file.saveCopy (Save a Copy…,
Cmd+Alt+S) and file.revert; the first save over an upgraded file keeps
"<name> (schema vN backup).fcproj". Project.version dropped (the envelope carries it).
- Hand-made v1 fixtures (minimal + edit without later serde-default fields) in
crates/format/tests/fixtures; 2,000-clip encode/decode timing test.
- docs/project-files.md.
