internal/source/webhook routes inbound POSTs to inbox events via a
configured table. Each route specifies recipient, type, priority, and
a Go text/template payload renderer that consumes the request body
decoded as JSON.
v1 binds loopback only — New() rejects non-loopback addresses at
construction. Caddy + bearer-token reverse-proxy is the v2 upgrade
path per spec §4.
Behavior:
- POST + matched route + valid JSON body → render template, emit, 202
- Missing route → 404
- Wrong method → 405
- Bad JSON → 400
- Template render failure → 500
- Emit failure → 500 (caller responsible for retry; HTTP source has no
durable staging)
- Empty body → empty data map for template (lets fixed-string templates
work without sending {})
- 1 MiB request body cap
GET /health returns JSON Stats{received, emitted, errors, uptime_sec}
on the same listener for journalctl correlation per spec §3.5.
10 tests passing — non-loopback rejection, bad type/template
rejection, route+template happy path, priority defaulting, empty body,
404/400/405/500, health endpoint counters.
31 tests across the three internal packages, all passing.
