Replace the hand-rolled `new Promise((resolve) => execFile(…, cb))` wrappers in
probe / ytdlp (×2) / ffmpeg / indexer.probeFlat / download.probeMeta with one
lib/exec.ts execFileAsync returning a normalized
{ok,stdout,stderr,timedOut,error} that never rejects. Each caller keeps its own
error mapping (timedOut -> "Timed out …" vs stderr) and JSON parsing; behaviour
is unchanged. windowsHide defaults on; per-call timeout/maxBuffer preserved.
Foundation for CC4/CC5 — the stdout line-buffer half lands with SIMP5, the
net.request half with SIMP16, at which point those checkboxes close.
Unit-tested (exec.test.ts) against the node binary: ok / stderr+nonzero-exit /
missing-binary / timeout. typecheck + 262 tests + eslint + prettier green.

L46: Introduced YTDLP_MISSING_MSG constant in binaries.ts. All four callers
(download, indexer, probe, ytdlp) now emit the same user-facing string:
"yt-dlp.exe is missing. Open Settings -> Software update to re-download it."
This removes newline-embedded messages and four divergent phrasings.
L71: Removed readOnly from videoDir/audioDir folder inputs in SettingsView.
Added onChange handler so users can paste or type a path directly without
being forced to use the Browse button. The path still flows through
applySettings() in main, which validates it.
L74: Accent color swatches were triple-labeled (aria-pressed + aria-label +
title). Replaced with a single aria-label that embeds "(selected)" state,
plus title for the hover tooltip. Removed the incorrect aria-pressed
(these are selection buttons, not toggles).
typecheck + 242 tests green.

yt-dlp is now a managed, auto-updating binary rather than a static bundled
one. On launch AeroFetch seeds a writable copy under userData from the
bundled seed, self-heals it if it goes missing, and — throttled to once a
day — self-updates it to the configured channel (default: nightly). This
keeps the binary current so YouTube changes don't silently cause 403s, and
an app reinstall (or portable re-extraction) can no longer roll it back.
Settings shows an auto-update toggle, the live version, last-checked time,
and the channel selector.
Also surface the bundled ffmpeg/ffprobe versions in Settings (display only:
they have no self-update path and, unlike yt-dlp, don't break as sites
change, so there is no auto-update for them).
- binaries: split the read-only bundled seed from the managed userData copy
- ytdlp: ensureManagedYtdlp (seed + self-heal), startup auto-update runner
- ytdlpPolicy: pure once-a-day throttle decision (unit-tested)
- ffmpeg: parse ffmpeg/ffprobe -version for the Settings panel
- settings/ipc/preload/renderer: new settings, IPC channels, types, and UI

Seven-tier security audit of the main process, each finding fixed with a
regression test. Typecheck (node + web) clean; unit tests 106 -> 140.
- Tier 1 (command exec/argv): allowlist the yt-dlp --update-to channel
(blocks arbitrary-binary-install RCE); gate per-download extraArgs behind
the customCommandEnabled consent flag in main (blocks --exec RCE); resolve
taskkill/schtasks by absolute System32 path; validate per-download
outputDir; normalize the URL in assertHttpUrl and use it at every spawn.
- Tier 2 (input validation): fix isSafeFilenameTemplate drive-relative
('C:foo') and Windows dotted-'..' traversal bypasses; percent-encode the
untrusted id in entryUrl; catch reserved device names with extensions in
sanitizeDirSegment.
- Tier 3 (fs/backup): drop malformed template rows in importBackup;
normalize deep-link URLs via assertHttpUrl.
- Tier 4 (cookies): confine the sign-in window's navigations/popups to web
URLs (recursively) and deny all web permissions on its session.
- Tier 5 (deep-link/argv): bound the .url file read to 64 KB; match the
aerofetch:// scheme case-insensitively.
- Tier 6 (Electron window): deny camera/mic/geolocation/USB/HID/serial/
Bluetooth permissions on the app window.
- Tier 7 (network/persistence): restrict the watched-source RSS fetch to
youtube.com feed URLs (SSRF guard); complete isValidSource validation.

Phase C had been implemented in the working tree but never committed:
named custom-command templates (CRUD + per-download override), command
preview, and the in-app yt-dlp self-updater.
Phase D adds: history search/kind-filter/multi-select/bulk-delete/
re-download; native OS notifications on completion/failure; a private/
incognito download mode that skips history; settings+template backup/
restore via JSON; and a persistent error log surfaced as a Diagnostics
report in Settings.
See ROADMAP.md for the full per-item breakdown.

Phase A of the Seal feature-parity roadmap: configurable post-processing via a
shared DownloadOptions model (src/shared/ipc.ts), editable as persisted defaults
in Settings and overridable per-download in the download bar.
- audio formats (mp3/m4a/opus/flac/wav/aac), video container (mp4/mkv/webm),
preferred-codec sort (-S vcodec)
- subtitles (download/embed/langs/auto), SponsorBlock (remove/mark + categories
+ force-keyframes-at-cuts), embed chapters/metadata/thumbnail, square-crop
audio artwork
- playlist downloads: probe via `-J --flat-playlist`, inline selection UI
(checkbox list, select-all/none, live count); each entry enqueued as its own
single-video download, reusing the existing queue/concurrency/history
- reusable DownloadOptionsForm shared by Settings and the download bar so the
defaults and per-download override never drift
- ROADMAP.md tracking full Seal parity (phases A-E)
Also includes in-tree security hardening that landed alongside: preload sandbox
(CJS preload output), http(s)-only window-open + blocked renderer navigation,
argv-injection guard for URLs (src/main/url.ts), extension-allowlisted file
open/reveal (src/main/reveal.ts), yt-dlp version-check timeout, and a minimal
window.electron presence marker.

Electron + React (Fluent UI) desktop frontend for yt-dlp:
- Download queue with live progress, concurrency cap, cancel/retry
- Format/quality picker via yt-dlp probe; audio extraction to MP3
- Settings + history persistence (electron-store / JSON)
- Clipboard link auto-detect; persisted light/dark theme
- NSIS + portable packaging (binaries bundled at build time, not in git)
UI: "Studio" sidebar layout with a toffee-brown theme (light + neutral dark).
Dropdowns use a native <select> and tooltips a CSS-only Hint, to avoid a
dev-machine GPU overlay flicker/blank issue.
