Adds the Mailpit HTTP API client used by BDD scenarios to assert on
emails sent during a test. Implements the per-recipient query/await/
purge pattern from ADR-0030.
Build-tag-gated integration tests run against the live Mailpit at
localhost:8025 (started via docker compose up -d mailpit).
Three operations on the client:
- MessagesTo(ctx, to) — list message IDs for a recipient
- Get(ctx, id) — fetch full message content (text, html,
headers, subject, etc.)
- AwaitMessageTo(ctx, to, — poll until a message arrives or timeout
timeout) (50ms polls, fail-fast on ctx cancel)
- PurgeMessagesTo(ctx, to) — delete all messages for a recipient
Tests in client_integration_test.go (build tag `integration`):
- RoundTrip: SMTP submit → list → get → assert subject/text — proves
the BDD-helper contract end-to-end via real SMTP
- AwaitTimeoutWhenNoMessage: bounded wait when no email arrives
- PurgeIsolation: per-recipient delete does NOT affect other recipients
Mailpit API quirk discovered + documented (Q-NNN candidate):
- /api/v1/messages?query=... is for PAGINATION, not filtering — the
`query` param there is silently ignored for filtering
- /api/v1/search?query=to:<addr> is the correct endpoint for filtering
AND the matching DELETE
- ADR-0030 + EMAIL.md updated with the correct endpoint
Run integration tests:
docker compose up -d mailpit
go test -tags integration -race ./pkg/bdd/mailpit/...

🐛 fix(bdd): shouldEnableV2 wrongly matched ~@v2 as @v2 substring + new gate regression scenario (#57)
