## Log
- **2026-10-08:** H.265 (HEVC Main, 8-bit 4:2:0, SDR) export on Windows through NVENC (#30): the NVENC session, ring and NV12 path of the H.264 encoder now serve both codecs (the H.264 export is byte-for-byte unchanged); the format is available where the GPU has an HEVC encoder, choosing it is the opt-in, and `hvcC` is built from the SPS the encoder wrote. ffprobe reads `hevc` / `Main` / `hvc1` / `yuv420p` / BT.709; our own HEVC decoder decodes it at 48.9 dB luma PSNR (RTX 5060). Main 10 and HDR remain.
+- **2026-10-08 (#285):** `filmcraft-cli` no longer panics with "Broken pipe" when its stdout is closed early (`filmcraft-cli commands | head`): later output is dropped, the rest of the work (script lines, `--save`, `--save-as`) still runs, and the exit status still reports failures. Other stdout write errors are reported and make the exit status 1. No change to the checklist or estimates.
- **2026-10-06:** 21 community PRs landed (#19, #28, #38, #39, #41–#60). Highlights: hardware decoding is now actually on in the desktop app (#41: `register()` sat inside a `log::info!` that never ran, so #33's VideoToolbox path only worked in the CLI and benchmarks); decode memory on long timelines cut sharply (frame pool, shared GOP-cache budget, positional file reads); exports are byte-identical across machines (#19); crash fix for odd track names over MCP (#44); ripple trim, ripple delete and speed changes move split-edit clips once (#56–#58); Japanese interface using an installed system font (#38; no fonts bundled); MCP annotations, resources, export progress and cancellation (#28).

+//! The desktop app's logger: `log::` records go to standard error and to a log file.
+//!
+//! Without a logger every `log::warn!`/`log::error!` in the workspace (GPU compositor fallbacks,
+//! audio output problems, a panicked frame job or audio mixer, container warnings) vanished. A
+//! launch from a desktop menu has no terminal, so the file is what a bug report can attach:
+//! `/Logs/filmcraft.log`, next to the crash logs (`--data-dir`, `FILMCRAFT_DATA_DIR` or
+//! `filmcraft_engine::autosave::default_data_dir`; Help ▸ Reveal Log Files opens the folder). Each
+//! start moves the previous log to `filmcraft.1.log` (and that one to `.2`), so the log of a run
+//! that crashed survives the next launch.
+//!
+//! Levels: `info` for FilmCraft's own crates, `warn` for everything else (wgpu and naga are
+//! chatty). `RUST_LOG` replaces that with env_logger-style directives: `debug`,
+//! `warn,filmcraft_codecs=trace`, `wgpu_core=info`. A directive ending in `*` matches every target
+//! that starts with it (`filmcraft*=debug`).
+//!
+//! Records logged before the data directory is known are kept (up to [`MAX_PENDING`]) and written
+//! once the file is attached. Writing never panics: a file that can't be created or written leaves
+//! standard error as the only sink.
+//!
+//! Realtime audio: the cpal callbacks (`audio.rs`, `audio_in.rs`, the play-ahead reader) do not
+//! log; they report through flags and a one-time `eprintln!`. A record takes the sink lock only for
+//! one `write_all` of an already formatted line (standard error is written outside the lock), so a
+//! logging thread such as the audio mixer never waits on more than one other line being written.
