- MongoDB replaced by InfluxDB 2 (one bucket, installationId tag).
Consumption is stored per chunk at its recordedAt and summed on read,
so a chunk the car re-sends from its cache overwrites itself instead
of being counted twice ($inc did count it twice). Lifetime is a
running total derived on read.
- POST /v1/telemetry takes batches of samples in ABRP's tlm fields; every
field is bounded, unknown fields are dropped, unread signals stay absent.
- After a successful write the newest fresh sample is forwarded to ABRP
with ABRP_API_KEY / ABRP_USER_TOKEN from the server environment; rate
limited, never queued. The car no longer needs ABRP credentials.
- Self-hosting: standalone output, Dockerfile (tests run in the build,
runs as UID 10001), .env.example and README for the new setup.
- Dev shell gains Node 22 and InfluxDB 2.
Verified locally against InfluxDB 2.7.12: all endpoints, retry
idempotency, and the dashboard pages. Unit tests: 17 pass.

The standalone service in server/ was never deployed anywhere, and keeping it
alongside a Vercel app would mean maintaining two implementations of the same
validation rules. It is deleted; web/ is the only ingest path now. Its routes
live at /v1/... rather than under /api, so the Android client's URL building is
unchanged and CONSUMPTION_API_URL stays a bare origin.
Credentials are split in two. INGEST_TOKEN is baked into the published APK and
must be assumed extractable — anyone can unzip an APK and read its strings — so
it opens the PUT endpoints and nothing else. Reading the history needs the
dashboard password, which is never compiled into anything and reaches the
browser as an HMAC-signed httpOnly cookie. The MongoDB URI stays a server-side
environment variable; the car has never held one and still does not.
The dashboard is a phone-shaped reader for the same data: totals for energy
taken and paid, a daily energy chart, an efficiency trend, and every DC session
with its power/SOC curve. It reuses the head unit's OLED palette so the two read
as one app. Every page is a server component and the charts are hand-rolled SVG,
so the whole thing renders without shipping client JavaScript.
MongoClient is cached on globalThis: a fresh client per request means a fresh
pool per request, and Atlas starts refusing connections long before the traffic
would justify it. Index creation moved to the first write of each warm lambda,
since a serverless deployment has no boot step to hang it on.
