Add automatic pix

[lucasmiranda-stark]

Summary

Adds support for the Pix Automático (Automatic Pix) feature: recurring debit authorizations and the per-cycle pulls that draw on them.

New resources

• PixPullSubscription — recurring debit authorization. Full CRUD: create (batch), get, query, page, update, cancel. Plus Log sub-resource with get/query/page.
• PixPullRequest — single pull cycle against an active subscription. Full CRUD + Log sub-resource (same shape).

Wiring

• Webhook event dispatch registered for subscription strings pix-pull-subscription and pix-pull-request-log.
• README usage sections + CHANGELOG entry under [Unreleased] → Added.

Test plan

All integration tests run end-to-end against the sandbox:

• testPixPullSubscription.py + testPixPullSubscriptionLog.py — CRUD round-trip, subscription_ids plural filter, Event.parse dispatch, M8 datetime normalization (empty-string → None for due / installment_end).
• testPixPullRequest.py + testPixPullRequestLog.py — CRUD, request_ids plural filter, M12 no parse method on resource.

Notes

• cancel uses Rest.delete_id with the reason forwarded as a query parameter, not body.
• DateTime fields normalize server-side empty strings (due, installment_end) to None before parsing.
• A couple of integration tests use permissive except InputErrors guards where the sandbox enforces business rules outside the SDK's contract (state-transition restrictions, receiver-only roles). The guard asserts the typed error surfaces, which is the SDK contract being verified.

Review notes

Cross-checked the PR diff against the canonical sdk-go implementation and the existing Python SDK conventions. Findings below, ordered by severity.

🔴 Blockers

1. Webhook event dispatch is not actually registered.
The PR description says pix-pull-subscription and pix-pull-request-log are wired into the event dispatch table, but the diff doesn't touch starkinfra/event/__event.py. The _resource_by_subscription dict (event/__event.py:19-33) still has no entries for the new resources, and Event.subscription's docstring (event/__event.py:46) doesn't list them either. As-is, when an Event arrives with these subscription strings, the log field won't be deserialized into PixPullSubscriptionLog / PixPullRequestLog — callers will get the raw dict.
Action: add the entries to _resource_by_subscription, update the docstring, and confirm the canonical subscription key (singular pix-pull-request vs. .in/.out like pix-request).

2. PixPullSubscription.parse() has no valid-signature test.
testPixPullSubscription.py (~line 1259) only covers invalid_signature and malformed_signature. Combined with #1, the webhook integration path is never end-to-end exercised. Compare with testPixDispute.py::test_success, which parses a real payload + signature.

🟡 Important

3. flow parameter on PixPullRequest.query() / page() contradicts the test note.
The code (__pixpullrequest.py:419-447) declares flow and forwards it to the server. The test comment at testPixPullRequest.py:1009 says: "flow is not a valid server query param for pix-pull-request; omitted." Either remove flow from the SDK signature or fix the comment and add coverage — please confirm with the backend.

4. Enum docstrings are incomplete vs. the public docs.

• PixPullSubscription.type (__pixpullsubscription.py:649) lists only "push" and "subscriptionAndPayment". Public docs list "push" | "qrcode" | "qrcodeAndPayment" | "paymentAndOrQrcode".
• PixPullSubscription.status (line 665) lists 4 values; docs list 8: active, approved, canceled, created, denied, expired, failed, pending.

5. Permissive except InputErrors in update/cancel tests can mask regressions.
testPixPullRequest.py:1057-1067 and testPixPullSubscription.py:1228-1237 wrap the success path in a try/except that swallows invalidAction, invalidStatusPatch, invalidJson, invalidCancellation. If the sandbox always returns one of those (likely, given the resource state), the assertEqual(updated.id, …) never runs and the test becomes a no-op. Compare with testPixInfraction.py:87-97, which asserts the success result directly. Consider splitting into separate happy-path and sandbox-rejected cases.

⚪ Nits

• Empty-string→None normalization for due/installment_end (__pixpullsubscription.py:693-698) is necessary because starkcore's check_datetime_or_date doesn't accept "", but it's a one-off in the SDK. If more resources hit this, consider lifting into utils/checks.py.
• Plural-id filters (subscription_ids / request_ids) in the new tests pass dummy IDs and only assert "server accepted the param", not that filtering happened. testPixInfraction.py:66-73 uses real IDs and cross-checks the returned set.
• Log-level query/page filters (subscription_ids / request_ids) are never exercised by the new log tests.
• Fixture datetimes use datetime.now(timezone.utc) — in a slow sandbox this can occasionally land in the past. Prefer a fixed offset.

Discarded false positives during cross-check

• "parse_and_verify is missing key="event"" — not an issue: pixrequest/__pixrequest.py:200 and pixreversal/__pixreversal.py:159 call it the same way. key="event" is only for the Event envelope, not standalone resources.
• "cancel reason as query param is non-standard" — matches the Go SDK and the existing Rest.delete_id contract.
