This pull request introduces managed-mode support for OpenHound, enabling integration with AWS Secrets Manager for BHE credential management and adding a managed collector job queue API. It also improves configuration management, enhances the BloodHound Enterprise client with managed credential refresh and new endpoints, and updates test coverage and dependencies.
Managed mode and AWS integration:
Added new configuration options (openhound.managed and [openhound.aws_secrets_manager]) to support managed deployments, including reading BHE HMAC credentials from AWS Secrets Manager and configuring scheduler polling intervals.
Implemented AWSBHECredentials in bhe_credentials.py to securely retrieve and validate BHE credentials from AWS Secrets Manager, with robust error handling and polling support.
Updated dependencies to include boto3 and filelock for AWS integration and concurrency control.
BloodHound Enterprise client enhancements:
Extended the BloodHoundEnterprise client to support managed credential refresh on 401 errors and added endpoints for managed collector job queue operations (available_collector_jobs, claim_managed_job), following new API path conventions to avoid ad blocker interference.
Updated the HTTP request logic to handle both bytes and BinaryIO bodies, ensuring correct HMAC calculation and stream handling for large uploads.
Documentation and guidance:
Added AGENTS.md to document repository guidance, including the new managed collector job queue API path requirements and BloodHound API contract practices.
Testing and CI:
Enhanced CI workflow to run new tests for AWS Secrets Manager integration, managed configuration, and the AWS profile adapter.
These changes collectively enable secure, managed deployments of OpenHound with AWS integration and improved maintainability for both configuration and client logic.

Walkthrough
The pull request adds managed collector execution alongside the existing unmanaged path. It adds AWS Secrets Manager credential retrieval, managed BHE job operations, scoped job configuration and AWS profiles, worker logging support, and scheduler handling for staged output and job reporting.
Adds managed-mode settings and logging defaults. Startup loads BHE credentials from AWS Secrets Manager in managed mode and retains DLT-secret credentials in unmanaged mode.
AWS secret retrieval and BHE credential bootstrap src/openhound/core/clients/aws_secrets_manager.py, tests/test_aws_secrets_manager.py
Adds single and batched secret retrieval, payload parsing, typed retrieval failures, and structured diagnostics. Tests cover retrieval, batching, error classification, and log output.
Managed job API and request bodies src/openhound/core/clients/bloodhound_enterprise.py, src/openhound/core/clients/models/jobs.py, src/openhound/core/clients/bloodhound.py, tests/test_collector_job_ingest.py, tests/test_data/api/jobs/*, AGENTS.md
Adds managed job polling, claiming, lifecycle calls, and data uploads. Job models and streaming request-body signing support these calls.
Job configuration and AWS profiles src/openhound/scheduler/configuration.py, src/openhound/scheduler/aws_profile.py, tests/test_managed_configuration.py, tests/test_aws_profile_adapter.py, tests/test_data/managed_aws_*
Adds per-job parameter and secret resolution, credential validation, temporary AWS profile files, and provider/environment cleanup.
Worker logging and redaction src/openhound/core/logging.py, tests/test_log_handlers.py
Adds worker log forwarding and redaction. Logging tests cover format selection, routing, exceptions, spawned workers, and shutdown.
Managed scheduler lifecycle and result upload src/openhound/scheduler/service.py, src/openhound/scheduler/dataflow.py, tests/test_scheduler_dataflow.py, .github/workflows/test.yml
Adds managed job claim and execution paths, staged output uploads, and outcome reporting. The dataflow accepts an optional output path, and the workflow runs the new test groups.

Merge Risk: Low · previous review 2759b
Managed collection works in the main paths, but a few edge cases need cleanup. A malformed log call in a worker can fail a managed job. Some upload rejections are retried until the claim expires and are then discarded without their reason. Blank AWS key values are not rejected up front. Several new tests do not run in CI. These are bounded and can be fixed before or shortly after merge.

Catch formatting errors in _ValueRedactor.filter.
logging.Handler.handle runs filters outside the try/handleError protection in emit. If record.getMessage() raises inside filter, the exception goes back to the code that made the logging call. A mismatched % format or an object whose __str__ raises can cause this.
Without a redactor, the stdlib catches the same error in emit and reports it through handleError. With this change, the error escapes whenever a redactor is active.
In a worker, redact_log_values attaches the redactor to _worker_handler for the whole collection (service.py worker wrapper). A malformed log call in OpenHound, DLT, or an extension can then raise TypeError and fail the managed job.
Catch the error, replace the message with a fixed placeholder, and drop the arguments. Do not include the unredacted message or arguments in the placeholder.

Reject blank raw AWS key values in AWSAccessKeyCredentials.
__post_init__ checks only the type of each field, so it accepts "". prepare_aws_credentials also checks only job.external_secret_key_id is not None. An empty key ID or an empty secret from load_secret therefore reaches the constructor at line 124. _write_ini then writes an empty aws_access_key_id or aws_secret_access_key into the profile, and the SDK can fail later with an authentication error that does not identify the empty field. Rejecting blank values here raises AWSAccessKeyError before managed_aws_profile installs a profile.

Treat deterministic 4xx upload rejections as job failures. Do not retry them.
The handler sets upload_failure only for HTTP 400, 401, 403, and 415. Other client errors, such as 413 or 422, reach raise. _poll catches the exception, keeps the result, and retries the same upload on every poll. The response does not change between attempts. Managed heartbeats are disabled, so the claim eventually expires. BHE then returns 404/409, and _abort_managed_job discards the job without reporting the real rejection reason. Classify every 4xx except 404, 408, 409, and 429 as a terminal upload failure.
