* feat(api-tokens): switch to sen_sk_ prefixed opaque keys
Replace JWT-shaped API tokens with 56-char opaque keys of the form
`sen_sk_<43-char base62 random><6-char base62 checksum>` (256-bit
entropy, sha256-truncated checksum). Node-proxy tokens stay JWTs.
Why:
* The api_token path was already a sha256 DB lookup; the JWT signature
was wasted work and the 400d JWT ceiling vs DB expires_at was a
confusing dual bound.
* Opaque tokens carry a verifiable checksum so malformed/typoed values
are rejected before any SQLite lookup.
* `sen_sk_` prefix is recognizable to GitHub, TruffleHog, GitGuardian
and makes the on-wire shape visually distinct from node_proxy JWTs.
Changes:
* New `utils/apiTokenFormat.ts` (generate + checksum-verify, CSPRNG via
randomInt, timingSafeEqual on the checksum compare).
* `middleware/auth.ts` and `websocket/upgradeHandler.ts` route opaque
tokens before any jwt.verify; 401 messages unified to avoid a
token-existence oracle.
* `middleware/rateLimiters.ts` short-circuits opaque tokens in the
node_proxy detection and keys per-token via a non-reversible sha256
slice so each token keeps its own bucket without a DB hit.
* All six existing tests migrated from jwt.sign({scope:'api_token'})
to generateApiToken(); new format-only test suite covering prefix,
length, alphabet, checksum reject paths, and a 10k-iteration
collision/integrity loop.
* Docs (features/api-tokens.mdx, api-reference/overview.mdx) describe
the shape and drop the obsolete JWT-ceiling note.
* fix(api-tokens): clear CI lint and CodeQL false positives
* Drop unused TEST_USERNAME import in remote-console-session.test.ts;
the migration to generateApiToken() left it orphaned.
* Add a CodeQL barrier model so `generateApiToken`'s ReturnValue does
not flow into the `insufficient-password-hash` query. The function
emits 256-bit CSPRNG opaque keys; sha256 of the raw token is the
correct construction for high-entropy API tokens (bcrypt-class
hashes target low-entropy human passwords). CodeQL's name heuristic
was treating "Token" as a password source and flagging the standard
sha256 wrapping at all 9 call sites.
* ci(codeql): exclude js/insufficient-password-hash for token paths
The previous barrierModel data extension was a no-op for this rule: the
js/insufficient-password-hash query identifies its "password" sources via
SensitiveExpr's name heuristic ("token", "secret", "key" substrings),
which is upstream of the taint-tracking layer where barrierModel applies.
Verified by post-push re-analysis: 9 alerts still open, all undismissed.
Replace the dead extension with a path-scoped query-filter in
codeql-config.yml so the rule no longer fires on apiTokenFormat,
apiTokens, and the test directory. Real user-password hashing code
elsewhere in the repo (auth, users, setup routes) remains analyzed.
The 9 existing alerts on PR #1062 are dismissed via API as false
positives with a justification pointing at this config. Future runs
will not re-flag them because of the path filter.

What Sencho is
Sencho is for homelab operators, small DevOps teams, and platform engineers who run services on Docker Compose, want a graphical interface without giving up file-on-disk workflows, and need to manage more than one machine without SSH gymnastics or a VPN.
It runs as a single container on your hardware and gives you a UI for the work you currently do over SSH on compose stacks: deploying, editing files, watching logs, restarting containers, browsing volumes, and recovering from failures. Your compose files stay on the host filesystem and remain the source of truth.
A Sencho instance is autonomous. To manage another machine, you install a second Sencho on it and connect them with a long-lived API token; the primary dashboard then acts as a transparent HTTPS proxy across your fleet. There is no SSH and no exposed Docker socket. For nodes behind NAT or strict firewalls, the Pilot Agent establishes a single outbound WebSocket tunnel to the primary, so the remote host opens no inbound port at all.
Most capabilities are free in the Community tier. A few advanced automation and fleet-control features ship in paid tiers; pricing lives at sencho.io/pricing.

Quick start
Sencho runs in a single container.
services:
sencho:
image: saelix/sencho:latest
container_name: sencho
restart: unless-stopped
ports:
- "1852:1852"
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- ./data:/app/data
# 1:1 Compose Path Rule: the host path MUST match the container path
- /opt/docker:/opt/docker
environment:
- COMPOSE_DIR=/opt/docker
- DATA_DIR=/app/data
docker compose up -d
Open http://your-server:1852 and create your admin account.
Always front Sencho with a TLS-terminating reverse proxy in production. See the self-hosting guide for hardening, environment variables, and reverse-proxy examples.
Run with docker run instead
docker run -d --name sencho \
-p 1852:1852 \
-v /var/run/docker.sock:/var/run/docker.sock \
-v sencho_data:/app/data \
-e COMPOSE_DIR=/opt/docker \
saelix/sencho:latest
For the full walkthrough, see the quickstart guide.
Adding remote nodes
To manage a second machine, install Sencho on it the same way, then add it from the primary dashboard with its URL and a long-lived API token. The primary proxies authenticated HTTPS and WebSocket requests to the remote instance. No SSH, no exposed Docker socket, no agent process on the remote. Nodes behind NAT or strict firewalls can opt into the Pilot Agent for outbound-only connectivity.
See the multi-node guide for the full token-bearer flow.
