Half of this binary's js.Publish calls were bound to no stream at all.
The streams were declared only by an external Python script on another
machine (Birock/doormile-bookings/setup_jetstream.py) and had drifted
from the code: booking.cancelled, booking.outcome and
booking.assignment_failed had no stream, and CHAT declared the literal
"chat.room.closed" while chat.go publishes "chat.room.closed.<id>",
which it does not match. Every publish site is best-effort
(`if db.Js != nil` + warn-log), so those events were failing and being
dropped silently — every cancellation, delivery outcome and assignment
failure since the streams were created.
db.EnsureStreams now declares the streams at startup from a map that
sits next to the code that publishes, so the contract cannot drift
again. It only ever adds: existing streams keep their storage type,
retention, limits and every subject they already have. Nothing is
deleted. Losing the create race against a sibling replica is expected
and reconciles rather than erroring.
Alongside that, /internal/miler/* ingests rider telemetry still arriving
over the jupiter NATS chain. The forwarding worker holds no rider JWT —
the rider app is still jupiter-shaped — so LegacyMilerIdentity resolves
an identity from a header into c.Locals("userid") behind the existing
X-Internal-Key guard. That lets the routes reuse the miler handlers
unchanged instead of growing a parallel set that would drift.
Identity comes from a header, never the body: the telemetry handlers
overwrite a body-supplied userid precisely so one rider cannot write
another's GPS trail, and reading it from the body here would reopen that
from behind the internal key. MilerProfile.Legacyuserid (nullable,
indexed) maps a jupiter userid to a Doormile one.
Only fire-and-forget telemetry is exposed. Transactional actions stay
synchronous — a rider needs a real answer from pickup-complete, which a
queue in front of it cannot give.
