Closes deferred Phase-9 item 1 (testcontainers full-flow test) and
exercises the Phase 10 dedup gate, retention loop, and notify writeback
end to end.
internal/event/integration_test.go (build tag integration):
- TestIntegration_FullCreateAndTriggerFlow: spins up testcontainers
Postgres + miniredis, builds the same chi router shape main.go uses
(RequestID + Recovery + tokenH.RegisterTriggerRoutes + /api subrouter
with /tokens POST). POSTs a webbug create, then GETs /c/{id} twice
from the same CF-Connecting-IP. Asserts: only one notification fires
(capturingSender callCount == 1), both events recorded (CountByToken
== 2), one event marked NotifySent + one NotifyDeduped, dedup INCR
bumped the Redis counter to "2", trigger_count == 2 on the token.
- TestIntegration_DifferentIPsBothNotify: same setup, three different
IPs each fire their own notification (no cross-IP dedup).
- TestIntegration_DedupTTLExpiry: builds an event.Service with 50ms
DedupTTL, records two events (second deduped), miniredis.FastForward
past TTL, third record notifies again — proves the SetNX TTL is the
authoritative window boundary.
- TestIntegration_RetentionLoopPrunes: inserts 7 events, runs
RunRetentionLoop with limit=3, asserts the table converges to 3
rows (newest kept) and the loop exits cleanly on context cancel.
The capturingSender is a notify.Sender impl; this lets us assert
on whether the dispatch goroutine actually called Send() without
mocking the HTTP layer of the real telegram/webhook senders.
