menzeljandClaude Opus 5 9247ff9621 Deploy stacks from a Git repository (0.58.0)
CI / check (push) Successful in 13m10s
CI / build-and-push (push) Successful in 3m50s
StackPilot's stacks were already plain folders on disk, which makes GitOps less
of an architectural change than it would be elsewhere: a sync is "make these
files match that repo, then compose up". Almost all of the design effort went
into the word "these", because getting it wrong destroys data.

A stack folder is not just the compose file. Compose creates bind-mount
directories in it — ./config, ./data — and those hold the live state of whatever
is running. So the obvious implementation, clone into the stack folder and
git reset --hard, is a data-loss bug waiting for its first `git clean`. Instead
the clone lives in a cache under ${DATA_DIR}/git/<stack> where reset and clean
are safe, and the configured subtree is copied across. No .git ends up in the
stack folder, so backups and the file browser are unaffected too.

Deletion is the other half. Making a folder "match" a repo naively means
removing what the repo does not have, which is exactly the application data
above. So each sync records the paths it wrote, and the next sync may delete
only those — a file the repository never provided cannot be touched by any code
path here. Tested directly: a database file and a hand-written .env survive a
sync that replaces the compose file and removes a file the repo dropped.

What the repo does provide is overwritten, hand edits included. That is the
point of GitOps rather than a wart, but it is a surprise if you attach a repo to
a stack you have been editing, so the connect form says it before the first sync
and the first sync is never automatic.

The webhook is the only route in StackPilot with no bearer token, because a Git
forge has none to present. It authenticates with an HMAC over the body —
X-Hub-Signature-256 for GitHub/Gitea/Forgejo, X-Gitlab-Token for GitLab, both
compared in constant time — and answers 404, not 403, to anything unsigned. A
403 would confirm that a given stack exists and is connected to a repository,
which an unauthenticated caller has not earned. The authorization matrix test
caught this route being public and made me write that reasoning down in it,
which is exactly what that test is for.

Credentials never reach a command line: ps is readable by every process on the
host, and this runs in a container next to everything else. The HTTPS token goes
to git through GIT_ASKPASS and the environment, the SSH key through a 0600 file
kept outside the working tree, and everything git prints is scrubbed of both —
plus any credential-carrying URL — before it is stored in last_error or shown.

Auto-deploy takes the same per-stack lock as every other lifecycle action, so a
webhook firing mid-deploy reports "files synced, stack busy" instead of racing a
second compose run at the same project.

The image needed git and openssh-client, which is the only reason this release
touches the Dockerfile.

26 tests against real repositories created with the real git binary, none of
them touching the network — mocking git would mostly test the mock. Verified end
to end as well: connect, sync, a push that changes one file and deletes another,
a wrongly signed webhook, a correctly signed one, and the live data still there
afterwards.

menzeljandClaude Opus 5 54c835b032 Close the read-side privilege escalation and fix proxy-aware IPs (0.44.0)
CI / build-and-push (push) Successful in 3m53s
F1 — Any authenticated user could read any file the backend could see.
/api/files/read and /download hung on get_current_user, and the sandbox that
should have caught that was open by default: ALLOWED_BROWSE_ROOTS contained
"/", for which _is_allowed() waves through every path. So the `user` role could
download stackpilot.db (password hashes, agent tokens, backup credentials),
every stack's .env and every .secrets/* file — with no audit trail, because
only mutations were logged.

Implementing that turned up three more doors into the same room, all fixed
here since closing only the first would have made the fix cosmetic:
GET /api/stacks/{id} handed the .env to any user, /export tarred the whole
stack dir including .secrets/*, and both the agent file proxies and
/api/agents/{id}/stacks/{id} repeated the leak for every remote host. All 24
filesystem-touching routes are now admin-only; reads and downloads are audited
(listing is not — the Files page polls it). DATA_DIR is refused outright, since
the API deliberately masks agent tokens and destination secrets and the browser
would otherwise be the way around that. "/" is out of the default browse roots.

F2 — Backup destination credentials were plaintext JSON in the DB, which is
what made F1 worth exploiting. They are now Fernet-encrypted at rest behind
parse_config/dump_config, with existing rows migrated at startup.

This needed a prerequisite from F6: the key is derived from SECRET_KEY, which
was regenerated on every boot when unset. Encrypting against a key that changes
per restart would be worse than plaintext, so an auto-generated SECRET_KEY is
now persisted to ${DATA_DIR}/secret_key at mode 0600. Sessions surviving a
restart is a welcome side effect.

F3 — /api/audit is admin-only. Also hidden from the dashboard and the nav for
non-admins, so nobody polls into a 403.

F4 — uvicorn now runs with --proxy-headers, so nginx's X-Forwarded-For is
honoured. Without it request.client.host was the frontend container's IP for
every request, which made the login rate limit global instead of per-IP (10
failures locked out everyone) and filled the audit log's IP column with one
useless value.

Verified: encrypt/decrypt round-trip incl. plaintext passthrough, idempotent
re-encryption and wrong-key handling; sandbox denial for DATA_DIR, traversal
into it, and paths outside the roots, with the allowed roots still reachable.
Both against stubbed settings — there is no Docker here, so nothing was run
end to end.
