secrets: vault dev and Centralis; render dev without common.yaml
Brings the last two credential stores under SOPS, so all three environments and
the control plane are managed the same way.

dev.yaml — dev was not "intentionally not wired in", it was broken

The vault README claimed dev had no real secrets. Both halves were false.

Dev needed secrets it did not have: thermograph-dev-daemon-1 has been in a crash
loop, restarting every ~60s with "neither THERMOGRAPH_INTERNAL_TOKEN nor
THERMOGRAPH_AUTH_SECRET is set; refusing to start" — so dev has had no Discord
gateway and no job timers. With THERMOGRAPH_BASE_URL unset the app also falls
back to https://thermograph.org, so dev's IndexNow pings and verification links
claimed to be prod. dev.yaml gives it its own generated AUTH_SECRET and a real
base URL, and 12 values total.

And dev already held production credentials: backend-deploy-dev.yml injects
S3_ACCESS_KEY/S3_SECRET_KEY into every dev deploy, and the only provisioned
keypair for that bucket is read-write — on the bucket holding prod's backups.
Dev does not need them; without bucket creds the lake service 503s and history
falls through to the archive. Those workflow lines still need removing.

dev renders dev.yaml ALONE, via THERMOGRAPH_SECRETS_SKIP_COMMON=1. Eleven of
common.yaml's sixteen values are live production credentials, the render is a
plaintext concatenation consumed through env_file:, and dev is the operator's
desktop AND the Forgejo runner executing unreviewed dev-branch code with the
docker socket mounted. An override in dev.yaml would not help — last-wins
governs consumers, but prod's value is still physically a line in the file.
Verified: current renderer leaks 28 lines onto dev including both S3 keypairs
and the VAPID private key; patched gives exactly 12 keys and no prod credential.
Beta's render is byte-identical either way.

centralis.prod.yaml — its own file, its own renderer

/etc/centralis.env was hand-edited, which is how a JSON registry got written
unquoted into a shell-sourced file tonight and silently collapsed three
identities to one. The renderer now owns the file.

It is service- AND environment-scoped, not folded into prod.yaml, because
/etc/thermograph.env is loaded into every container in the app stack. Folding
these in would put CENTRALIS_AUTH_TOKEN and CENTRALIS_TOKENS — which
authenticate an endpoint carrying run_on_host and sql_query(write) — into the
web backend's environment, turning a read-anything bug in the app into a
foothold on the control plane.

Quoting is guaranteed three ways rather than assumed. Critically, `sops -d
--output-type dotenv` emits values verbatim, so reusing the existing render path
would have reproduced tonight's bug exactly. The new function decrypts to JSON
and emits POSIX single-quoted assignments; it then sources its own output in a
clean shell and compares every value before touching /etc; and it refuses to
write unless CENTRALIS_TOKENS parses as a non-empty subject->token object after
sourcing. Tested against 16 hostile values including embedded quotes, newlines
and ;rm -rf /.

Value-identity proven, not asserted: rendered vs live compared as *effective*
values on prod (a textual diff would report a false difference, and would report
a false match if the vault had captured quote characters as part of the value),
plus both env files producing a byte-identical `docker compose config` digest.
9 keys, both token subjects preserved. Nothing deployed.

Note for later: /etc/thermograph.env is also shell-sourced, and survives on raw
dotenv only because none of its 32 current values contains a shell-special
character. It is one quoted secret away from the same bug.

thermograph-infra

Infrastructure for Thermograph: Terraform host provisioning, the SOPS+age secrets vault, Docker Swarm/WireGuard networking, Forgejo, Caddy, and the deploy scripts that run the already-built app image on each host. Extracted from the app monorepo (emi/thermograph) — the app repo owns building and testing the app; this repo owns running it.

  • terraform/ — provisions/configures hosts (SSH-driven by default; an optional GCP-creating module is scaffolded, no live resources yet) and triggers each deploy. See terraform/README.md.
  • deploy/secrets/ — the git-native SOPS+age secrets vault (every app secret, encrypted at rest, rendered at deploy time). See deploy/secrets/README.md.
  • deploy/swarm/, deploy/forgejo/ — the 3-node WireGuard/Swarm cluster that hosts Forgejo (git + CI + registry); does not run the app itself. See ACCESS.md and the READMEs under each directory.
  • deploy/deploy.sh — pulls the pinned app image (IMAGE_TAG) and rolls the compose stack; invoked by Terraform and by the app repo's .forgejo/workflows/deploy.yml over SSH.
  • docker-compose*.yml, docker-stack.yml — how the app image runs (compose in production today; docker-stack.yml is a design record for a possible future Swarm-based app deploy, not currently live).

The app's own source, Dockerfile, and build/test CI stay in the app repo — this repo never checks out app source; hosts only pull tagged images from the registry. See ACCESS.md for host access and the Swarm/Forgejo topology, and terraform/README.md for the day-to-day plan/apply workflow.

Branches & how changes reach each environment

  • main — what prod and beta run: their /opt/thermograph checkouts git reset --hard origin/main at the start of every deploy (deploy/deploy.sh). A merge to main reaches those hosts on the next app deploy (or a by-hand deploy.sh run); there is no separate infra deploy trigger.
  • dev — what LAN dev runs: ~/thermograph-dev resets to it via deploy/deploy-dev.sh. Keep it fast-forwarded to main (infra changes are not environment-staged today; the branches exist so LAN dev can trail or lead when needed).
  • release — currently consumed by nothing (prod tracks main, not release). It exists to mirror the app repos' dev→main→release promotion shape if per-environment infra staging is ever wanted; until then, treat main as live-everywhere.

Note the asymmetry with the app repos: app code IS environment-staged (dev→main→release maps to LAN→beta→prod via image tags), infra is not.
