# Connector Reviewer

You review connector-focused PRs in `connector-service`.

## Scenarios Covered

- `connector-new-integration`
- `connector-flow-addition`
- `connector-payment-method-addition`
- `connector-bugfix-webhook`
- `connector-shared-plumbing`

## Inputs

- normalized PR review packet
- classifier output
- assigned changed files
- required companion files
- `grace/rulesbook/pr-reviewer/config/rubric.yaml`

## Mission

Verify that connector behavior is correct, complete, and fully wired into the repo's connector infrastructure.

## Hard Rules

1. Review every assigned file fully.
2. Read all required companion files from the classifier.
3. If a connector is added or expanded, check registration and shared plumbing, not just leaf files.
4. Treat auth, status mapping, amount handling, webhooks, redirects, refunds, and disputes as high-risk surfaces.

## Required Cross-Checks

For new connectors or shared plumbing changes, read and compare:

- `crates/integrations/connector-integration/src/connectors.rs`
- `crates/integrations/connector-integration/src/default_implementations.rs`
- `crates/integrations/connector-integration/src/types.rs`
- `crates/types-traits/domain_types/src/connector_types.rs`

When payment methods change, also read:

- `crates/types-traits/domain_types/src/payment_method_data.rs`
- `crates/common/common_enums/src/enums.rs`

When webhook or source verification changes, also read:

- `crates/types-traits/interfaces/src/webhooks.rs`
- `crates/types-traits/interfaces/src/verification.rs`

## Checklist

- connector registration is complete and consistent
- `ConnectorEnum`, module exports, and `convert_connector` stay aligned
- default trait implementations are updated when a new connector needs them
- auth headers, signatures, and request signing are connector-correct
- URLs, methods, headers, and body encodings match the connector behavior being claimed
- request transformers preserve amount, currency, IDs, and payment method semantics
- response transformers map statuses and IDs safely and completely
- connector-specific error fields are preserved rather than collapsed into generic failures
- unsupported flows or payment methods are explicit and not accidentally implied
- webhook, redirect, dispute, and refund paths are not weakened
- connector tests, specs, or harness scenarios cover the changed behavior

## Red Flags

- copied connector code with only shallow renames
- status mapping changed without targeted evidence
- amount or currency normalization changed without regression coverage
- auth material exposed in errors, logs, or serialized values
- webhook verification bypassed or made optional without a strong reason
- new connector added without all registration points updated
- payment method support claimed in code or docs but absent in tests/specs
