A loop started by a far/early car would (a) give up before the REAL car settled at the barrier, and (b) swallow the real car's pushes (the #polling guard dropped them). So a confident-but-wrong far-car plate could win, or the intended car get debounced out after the loop ended — wrong car acted on, right car blocked. Fix: a push that JOINS a running loop now EXTENDS the deadline (lastPush + ANPR_POLL_WINDOW_MS) instead of being dropped, capped at start + ANPR_POLL_MAX_MS (30s) so a continuously-busy lane can't slide forever. Each tick still pulls a FRESH frame, so the loop tracks whoever is at the barrier NOW, not the car that started it. Per-camera sliding deadline in #pollDeadline (cleared with #polling in finally). +1 test (push mid-poll keeps the loop alive past the initial deadline); 171 server tests green. New knob ANPR_POLL_MAX_MS documented in the komodo env reference + the two concurrency guards written up in lane-presence-and-anpr-entry.

komodo/ — fleet deployment as code
Infra-as-code for the Komodo Core control plane that deploys the parking appliance to the
booth fleet over the NetBird mesh. See wiki/decisions/fleet-deployment-komodo.md for the
rationale, threat-model analysis, and the three settled choices (many/growing fleet · deploys
are manual + pinned · secrets are Komodo-managed, per-booth).
This directory does not change how images are built or how the app runs — it's only the
control plane. The booth still runs the same docker-compose.yml + docker-compose.prod.yml
(container-deployment); Komodo just drives them remotely instead of someone SSH-ing in to
run booth.sh.
Files
resources.toml— the Komodo resource definitions (Servers, Stacks, optional Builders/ Procedures), synced into Core via a ResourceSync. This is the reviewable, version- controlled source of truth for which booth runs what..env.komodo.example— the variables a Stack expects, documenting what comes from Core's secret store (per-boothJWT_SECRET/EVENT_SIGNING_KEY) vs. plain Stack env.
How Core consumes this (one-time)
In Komodo Core, create a ResourceSync pointing at this repo + path (komodo/resources.toml),
on the branch you manage from (e.g. main). Core reads the file and reconciles Servers/Stacks to
match. Thereafter, a PR to this directory + a sync is how you change the fleet — no clicking.
Komodo's TOML schema evolves across releases. Treat
resources.tomlas a starting sketch:resources.tomlmirrors the workingpark-buziStack (built by hand in the Core UI, then exported to TOML — so field names match the running Komodo version, v2.2). Import it into the sync Unmanaged first and review the diff; it should be ~empty against the live Stack.
How servers get created — NOT here
There is no [[server]] block in resources.toml. Servers are created by the Periphery
agent onboarding outbound: in Core, create a one-time Onboarding Key (Settings →
Onboarding), then install Periphery on the booth passing --onboarding-key + --core-address
(Core's reverse-proxy URL, reached over the NetBird mesh) + --connect-as=<booth-name>. The
agent self-registers, generates its own auto-rotating key pair (private key never leaves the
booth), and connects outbound — the booth opens no inbound port. The sync owns only the
Stack, which references the server by the name it onboarded as (server = "park-buzi"). See
wiki/decisions/fleet-deployment-komodo.md.
Adding booth N
Copy the [[stack]] block, change name, server (its onboarded name), and the per-booth
secret references ([[park_<site>_jwt_secret]], [[park_<site>_event_signing_key]]). Create
those secrets in Core's store first.
Hard rules encoded here (do not relax without updating the decision page)
- No deploy webhook on a booth Stack. Deploys are a human action; pin
TAG=dev-<sha>before a production booth goes live. A moving:devon a production booth is the non-determinism we rejected. (TAG=devhere is fine while staging.) - Onboarding, outbound, mesh-only. Servers self-register via an onboarding key; Periphery connects outbound to Core's mesh URL and exposes no inbound port. Never a LAN/WAN address.
- Secrets are per-booth and unique.
EVENT_SIGNING_KEYsigns the anti-fraud ledger — one leak must taint one booth, never the fleet. Reference Core secrets by name; never inline a real value in this file (it's in git). - Volumes preserved. The Stack must never run
compose down -v— that would wipe theparking-datavolume (the signed ledger). Komodo's "destroy" is gated for the same reason.
