Shallow clones were never a Gitea packing bug. An intruder had set
uploadpack.packObjectsHook in Gitea's HOME gitconfig, pointing at a
non-executable dropper, so every upload-pack died mid-pack. That hook is
gone and --depth=1 clones are verified working, so fetch-depth: 0 buys
nothing but slower CI. See INCIDENT-2026-08-11.md.
infra/Caddyfile was dead: ansible templates Caddyfile.j2 to
/etc/caddy/Caddyfile, and nothing ever deployed the static copy.

actions/checkout defaults to depth=1, and Gitea aborted generating that pack
with a bad pack header protocol error on all three retries, failing the build
before any image was pushed. A full fetch avoids the shallow-pack path.

Edge nodes are deployed to arbitrary locations by arbitrary people, so the
broker has to be reachable from the internet and secured on its own merits
rather than by a VPN.
Three defects made that impossible. The broker only had a plaintext 1883
listener; every node shared one drb-node password; and the ACL pattern used
%c, the client-supplied client id, so any holder of that shared password
could set client_id to another node and take over its namespace. The comment
claiming this cryptographically prevented cross-node access was wrong and is
gone.
Authentication now uses mosquitto 2.x's built-in dynamic-security plugin on
the stock eclipse-mosquitto image. c2-core administers it over the control
topic, creating each node's client on approval with username=<node_id> and
password=<its node_keys api_key>, attached to a role whose ACL is nodes/%u/#
against the authenticated username. One credential, one revocation point.
An HTTP-callback plugin was implemented first and rejected: that project is
archived upstream, which is not an acceptable dependency on an
internet-facing broker.
Because dynsec state is a second source of truth alongside Firestore,
approve/reissue/delete now write to the broker first and surface a 502
rather than drifting, and c2-core reconciles every approved node into dynsec
on startup.
Adds node self-enrollment (POST /nodes/enroll, GET /nodes/{id}/credentials)
so a new node can obtain its key over HTTPS without an operator handling
secrets by hand. Enrolling an already-approved node_id is refused on the
fleet token alone — otherwise a leaked token plus a guessable id would let
an attacker steal a live node's key before the real node asked for it.
Pickup secrets are stored hashed and returned once, and the endpoint is rate
limited per source IP.
Infrastructure: an 8883 TLS listener fed by Caddy's certificate via a
systemd path unit, a firewall rule for it, and Caddy now 404s /internal/*
so the api vhost cannot proxy internal routes.
Also fixes CORS, which allowed https://app.<domain> while the frontend is
served on the bare domain — every call from the portal would have failed —
and widens the vault gitignore to a glob, since ansible-vault leaves
backup siblings that the exact-name rule left committable.

- Terraform: e2-micro VM (us-east1-b, free tier), static IP, SSH/web
firewall rules, IAM bindings for Firestore + GCS; imports existing
drb-calls bucket and c2-server Firestore database into state
- Gitea CI: build c2-core, discord-bot, frontend images and push to
git.vpn.cusano.net registry; SSH deploy pulls pre-built images (no
build on VM)
- Ansible: first-time setup only — git clone, env files from vault,
Caddyfile, docker login + compose pull + up; no rsync or on-VM builds
- docker-compose: add image: ${REGISTRY}/name:latest alongside build:
so local dev and CI registry both work
- gitignore: add Terraform state, lock, tfvars, ansible secrets
