Round 4 was targeted at the surfaces rounds 2 and 3 changed. 29 findings raised, 26 survived deduplication, 12 survived three adversarial readings each. `set_delivery` renewed the claim but never checked it was still ours, while its sibling `release_send` always did. `expire_on_commit` is off, so the token it re-stamped came from the caller's own memory, not the row: a send that outlived its 600 s lease came back, overwrote the take-over send's committed links with a full-column write, and put its own dead token back. It now takes the token, reads the row's claim with a targeted scalar (not a refresh, which would discard the `issue_url` assigned one line earlier) and raises `SendClaimLost` rather than writing. An issue created by a send that had already lost its claim is logged with its number — that record is the only one that will exist. The tracker's settings are read above the pre-call checkpoint instead of inside `_client`. Reading them there was a SELECT one line after the commit that was meant to end the transaction, and held it — idle, snapshot pinned — across the repository check and the create. The comment and the module docstring said otherwise; measuring it in pg_stat_activity is what settled it. Two more comments were saying things the code had stopped doing: the `**state` spread does not carry the claim (`set_delivery` strips and re-stamps it), and react-query does not debounce the preview — the editor being unmounted is what paces it. The composer stopped stranding the focus on `<body>`: a send that creates the issue and then fails on an attachment unmounts the button that was just pressed, and only the success path handed the focus on. Export no longer saves into a refusal it does not need — the zip is the way out of a stuck send, and its pre-save was the one step that could not survive one. The delivery banner announces through a role instead of an `aria-live` created with its own message. `historyState` returns a union, so `chipTone` matching on the same keys is checked by tsc rather than by hope. PlexPlayer was the only full-screen overlay in the tree with no focus containment at all — Tab walked out of an opaque player into a page nobody can see. It now carries the shared trap. Closing that hole exposed the one underneath it: `useDismiss` registered as a layer that traps the Tab while installing no trap, so the player stood its own down for its own menus. Measured in a real browser: 30 Tabs with the settings panel open, 9 escapes into the nav rail, and 0 after. Escape ordering is unchanged — the panel first, then the player. Three tests that did not hold their line: the advisory lock's call site (deleting it left the suite green), the trail assertion whose `all()` was vacuous over an empty filter, and a `layerStack` assertion the stand-in dialog already forced. All eleven executable fixes mutation-checked red for the right reason; the two comment corrections have nothing to pin.
Siftlode
Your YouTube subscriptions, the way a feed should work. Siftlode pulls every upload from the channels you follow into one clean, filterable feed — no algorithm deciding what you see, and no Shorts or livestream noise unless you want it. Self-hosted, multi-user, and private: your data stays on your own server.
Everything expensive (channels, videos, metadata) is fetched from YouTube once and stored locally, so filtering, searching and sorting are instant and don't burn API quota. Click a video to watch it in an in-app player that resumes where you left off — or open it on youtube.com so your own ad blocker and SponsorBlock keep working.
Features
- A readable subscription feed — sort and filter by channel, tag, language, topic, length, upload date or watch state; hide channels without unsubscribing; save filter setups as named views.
- Search all of YouTube from the feed — live results you can play, save or add to playlists like any other video; they stay temporary and out of your catalog unless you keep one.
- Channel pages & a channel manager — per-channel stats and uploads, priorities, and your own tags to slice the feed by.
- Playlists with two-way YouTube sync — build them locally, keep them in sync in both directions.
- In-app player with resume, plus keyboard/scroll controls.
- Download Center — save videos to the server with yt-dlp in a Plex-friendly layout (format presets, per-user storage quota), trim / crop / split & join them in a built-in editor, then save to your device, share with another user, or hand out a public watch link.
- Plex library (optional) — point Siftlode at your own Plex server to browse and play its movies and shows alongside your feed, with watch state kept in sync.
- Multi-user with per-user private state, a shared catalog, and a fair daily API-quota guard.
- Self-hosted & private, with a first-run web setup wizard and the interface in English and Hungarian.
Quick start (self-hosting)
You don't need to build anything — Siftlode runs from a prebuilt public image, and all configuration (your admin account, Google sign-in, email) happens in a first-run web wizard. You need Docker with the Compose plugin.
1. Get the files and run the installer:
git clone https://git.b1fr0st.eu/peter/siftlode.git
cd siftlode
./install.sh # Windows (PowerShell): ./install.ps1
The installer generates a private .env (secrets), pulls the image, starts the app + database, and
prints a one-time setup URL like http://localhost:8080/setup?token=….
2. Finish in your browser. Open that URL and follow the wizard:
- Admin account — the email + password you'll sign in with.
- Google sign-in (optional) — paste a Google OAuth client to enable "Sign in with Google" and pulling your YouTube subscriptions. Skip it to use email + password only.
- Email / SMTP (optional) — for verification/notification emails. Skip it and you (the admin) simply approve new accounts yourself.
Then sign in with your admin account. That's it. See docs/self-hosting.md for the full walkthrough.
Just trying it out? Press Enter at the installer's URL prompt to run on
http://localhost:8080.
Build from source (alternative)
Prefer to build the image yourself instead of pulling it:
git clone https://git.b1fr0st.eu/peter/siftlode.git
cd siftlode
cp .env.example .env
# generate the two secrets and paste them into .env:
python -c "import secrets;print('SECRET_KEY='+secrets.token_urlsafe(48))"
python -c "import base64,os;print('TOKEN_ENCRYPTION_KEY='+base64.urlsafe_b64encode(os.urandom(32)).decode())"
docker compose up --build -d # builds from the included Dockerfile
Open http://localhost:8080 and finish in the setup wizard as above. (Set a POSTGRES_PASSWORD in
.env too.)
HTTPS / public access
Port 8080 over plain HTTP is fine for a LAN or a quick trial. For public access put a reverse
proxy (Caddy, Nginx, Traefik…) in front to terminate TLS, and set the public URL (the installer
prompt, or OAUTH_REDIRECT_URL in .env) to your https://… address — this also marks the session
cookie secure. Add that same …/auth/callback URL to your Google OAuth client's authorized redirect
URIs. Behind a proxy, also set TRUSTED_PROXY_IPS so the rate limiters see the real client IP and
can't be bypassed via a forged X-Forwarded-For — see docs/self-hosting.md.
Updating & backups
docker compose -f docker-compose.selfhost.yml pull # or: docker compose pull
docker compose -f docker-compose.selfhost.yml up -d
That follows latest, which moves with every release. Set IMAGE_TAG=0.80.0 in .env to pin a
version and upgrade on your own schedule; released versions are listed in CHANGELOG.md
and in the app's Release Notes. The registry keeps only the newest few of those, so a pin decides
when you take the next hop rather than letting you stay put forever — see
docs/self-hosting.md.
Back up before upgrading. Migrations run automatically on startup and are not undone by pulling
the old image back. A backup is the database dump plus your .env — TOKEN_ENCRYPTION_KEY is
what decrypts the Google, SMTP and Plex secrets stored in that database, so a dump restored without it
is only half an instance. Use scripts/backup.sh (or backup.ps1 on Windows) and scripts/restore.sh;
the equivalent one-liners, the pinning recipe and the rollback steps are in
docs/self-hosting.md.
How it works
- Shared catalog, private state. Channels and videos are stored once and shared; each user's subscriptions, tags, playlists and watch/save/hide state are private.
- Cheap by design. Public reads are cached locally; a shared daily quota budget and a background scheduler keep unattended syncing within YouTube's free API limits. An optional API key lets backfill run without depending on a user's OAuth token.
