Board minutes #62 Decision 2 (server-26#64), due 2026-08-31. CTO draft #60
finding 1 and CISO draft #61 finding 3 reached this independently.
GET/PUT /admin/features accepted only a Firebase admin token, so the unattended
runbook had no headless path and SSHed into the c2-core container to write
config/ai_features with the admin SDK. Moving a platform-wide AI cost switch
required a full container shell, and set_flags() wrote no audit entry either
way, so a flag flip was unattributable however it happened.
- New agent_service_key (AGENT_SERVICE_KEY), deliberately separate from the
Discord bot's service_key. Sharing one key would collapse two principals into
a single unattributable identity in every log line, and the bot has no
business flipping AI flags regardless.
- require_agent_key_or_admin accepts the agent key or a Firebase admin, and
rejects the Discord key. The "key is configured" guard is load-bearing:
compare_digest("", "") is a match, so a deployment that never set the key
would otherwise accept an empty credential.
- set_flags() writes an audit_log entry with before/after values and the actor,
wrapped so an audit failure cannot lose the flag write or 500 the route.
- Cascade helper sets the global doc and every system carrying an ai_flags
override in one call. A global False already beats everything, but a system
False beats a global True, so turning AI *on* could half-apply and leave a
radio system hot after shutoff. It scans for the override rather than
hardcoding the two known system IDs, so a new system cannot silently defeat
it.
- cascade defaults to False. PUT /systems/{id}/ai-flags and the AiFlagsPanel
toggle mean a per-system override is deliberate operator intent; cascading by
default would erase it on any unrelated global flip. The runbook opts in.
Issue items 5 and 6 (retiring the SSH path from drb-worksession.md) are NOT
done here and the runbook is untouched. The credential does not exist in
production yet, so the SSH path is still the only one that works; retiring it
now would break the next unattended run. Owner activation is recorded on #64.
Tests 273 -> 289.

Google sign-in fails in production: the popup opens, flashes, closes, and the
page shows a generic failure with nothing in the console or the network tab.
The app is served from drb.cusano.net while signInWithPopup opens its handler on
the project's firebaseapp.com origin. Chrome partitions third-party storage, so
the popup cannot read back the state its opener wrote and dies immediately.
Visiting the handler directly says so: "missing initial state ... a
storage-partitioned browser environment". Nothing about authorised domains or
the build was wrong -- the shipped bundle carries the correct apiKey and
authDomain, which is exactly what made this look like a code bug.
Caddy now proxies /__/auth/* on the bare domain to the Firebase Hosting origin,
rewriting Host so Firebase recognises the request. Same-site again, which is
Google's documented fix. The vhost becomes a `route` so the handler matches
before the catch-all proxy to Next.
The upstream host is a jinja default rather than a group_vars entry because
group_vars/all.yml is gitignored; override it there if the project ever moves.
Two manual steps remain, and all three parts are required or nothing changes:
the CI secret FIREBASE_AUTH_DOMAIN must become drb.cusano.net with a frontend
rebuild, and drb.cusano.net must be an authorised domain in the Firebase
console. This template also needs an ansible run -- CI alone will not deploy it.

upload_audio() could only sign a URL when GCP_CREDENTIALS_PATH pointed at a
service-account key file. The deployed VM runs on Application Default
Credentials with no key file, so every upload silently took the fallback
branch and returned a bare gs:// URI. That broke two things at once:
* Browsers cannot fetch a gs:// URI, so no recording was ever playable.
* _public_url_to_gcs_uri() only matched https://storage.googleapis.com/ and
returned None for it, so `if gcs_uri:` in the upload path was always false
and transcription never ran. Nothing was logged, which is why this looked
like an OpenAI credits problem rather than a storage one.
The fallback also interpolated the client-supplied filename instead of the
call_id-derived safe name, so the URI did not even name the object written.
Calls now store only the canonical gs:// location. A short-lived playback link
is minted per read as an HMAC over (call_id, expiry) keyed by SERVICE_KEY, and
audio is served from the private bucket by the new /media route. An <audio src>
cannot carry an Authorization header, so the link has to be the credential;
that router is therefore public with the check done inline, as enrollment.py
already does. Signing GCS URLs from the VM would have needed a
serviceAccountTokenCreator grant on its own service account — this avoids the
IAM change entirely and keeps the bucket private.
gcs_uri_for_call() reconstructs the object name from call_id, so recordings
made before this fix are reachable again without a data migration.
Frontend rows come straight from Firestore via onSnapshot and never see a
server-minted field, so CallRow fetches the link lazily on expand.
Also removes the last long-lived (1 year) signed URL and the log line that
printed it.
The broker crash-looped on every deploy: "Unable to load server certificate
/mosquitto/certs/mqtt.crt ... Permission denied". The cert-sync script wrote
600 root:root into a 0700 root:root directory, on the assumption that
mosquitto runs as root inside its container. It does not — the stock
eclipse-mosquitto entrypoint drops privileges to the in-image mosquitto
user, confirmed on the server as uid=1883(mosquitto) gid=1883(mosquitto),
and the broker's own log says so on every start.
Certs dir is now root:1883 0750 with the cert 0644 and the key 0640, and
the data dir is 1883:1883 recursively — recursively because mosquitto
WRITES dynamic-security.json there, and a root-owned file left by an
earlier deploy would still be unwritable after a directory-only chown.
Also drops the "unverified Caddy cert path" note: a real issuance confirmed
the path, producing CN=mqtt.drb.cusano.net signed by Let's Encrypt.

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.

Only drb.cusano.net and api.drb.cusano.net have public A records, so the
app.<domain> vhost had no cert to present and the bare domain — the record
that actually exists — matched no site at all, producing
ERR_SSL_PROTOCOL_ERROR in the browser.

Compose interpolates the top-level .env, so a password containing "$fP" was
read as the variable $fP and replaced with an empty string — hence the
repeated "The \"fP\" variable is not set" warnings on every compose command.
The env_file templates are not interpolated, so c2-core kept the literal
password while mosquitto's entrypoint received the mangled one. The two sides
disagreed and c2-core could not authenticate to the broker. Escaping $ as $$
here (and only here) makes compose collapse it back to the real value.

- 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
Provisions e2-micro VM (us-east1-b, free tier) with static IP, SSH and
web firewall rules, Docker + Caddy startup script, and IAM bindings for
Firestore and GCS access via ADC. Imports existing drb-calls bucket and
c2-server Firestore database into state. Ansible roles handle first-time
setup (swap, docker group) and all subsequent deploys via rsync + docker
compose, with secrets managed via Ansible Vault. DNS stays on AWS Route 53.
