Walkthrough

The changes update parent-company matching, organization approval removal, CLA Manager request decisions and conflict responses, and legacy company ordering by creation date.

Changes

Parent-company lookup

Layer / File(s) Summary
Parent row matching
cla-backend-go/company/repository_external_id.go, cla-backend-go/company/repository_external_id_test.go
Parent-company lookup reuses a row only when its canonical signing entity is empty. A test covers creating a parent row when only a row with a different signing entity exists.

Organization approval removal

Layer / File(s) Summary
Removal with no repositories
cla-backend-go/signatures/repository.go, cla-backend-go/signatures/approval_list_removal_test.go
Both repository lookup paths treat GitHubRepositoryNotFound as an empty repository set. A test checks that organization removal succeeds, updates the approval state, and does not look up members or invalidate signatures.

CLA Manager request decisions

Layer / File(s) Summary
Decision rules and approval ACL handling
cla-backend-go/v2/cla_manager/service.go, cla-backend-go/v2/cla_manager/requests.go, cla-backend-go/v2/cla_manager/requests_test.go
Approval and denial return an already-decided error when a request is not pending. Approval checks whether the requester is in the signature ACL, reconciles ACL update errors with a signature read, and attempts to restore pending status when approval cannot continue. Tests cover decision conflicts, ACL results, and recovery behavior.
Conflict responses and API contract
cla-backend-go/v2/cla_manager/handlers.go, cla-backend-go/swagger/cla.v2.yaml, docs/M3_ORG_LENS_API.md
The approve and deny handlers return conflict responses for already-decided requests. The API specification and lifecycle documentation describe the 409 response.

Legacy company ordering

Layer / File(s) Summary
Creation-date ordering
cla-backend-legacy/internal/store/companies.go, cla-backend-legacy/internal/store/companies_test.go
The company comparator orders parsed creation dates chronologically and uses the smaller company ID when the dates represent the same instant. Tests cover mixed formats and equal instants.

Merge Risk: 🟡 Moderate · up to 11ca6

Concurrent decisions can leave request status and manager access inconsistent, and parent lookup can create a duplicate record. These risks should be fixed or explicitly accepted before merging.

Review comments at @cla-backend-go/company/repository_external_id.go:
- Line 96: Update the converter used by GetCompaniesByExternalID to classify
parent candidates with canonicalSigningEntity instead of raw string equality, so
case and surrounding whitespace differences are treated consistently with the
lookup-result guard.

Review comments at @cla-backend-go/v2/cla_manager/requests.go:
- Line 82: Update the status guard in the ApproveRequest flow so a retry can
complete AddCLAManager when the request is already approved but the requester is
missing from the signature ACL; alternatively, ensure a failed AddCLAManager
does not finalize the request status.
- Line 183: Update the v1 DynamoDB status update used by the v2 approval and
denial methods to atomically require the stored status to be pending, so
concurrent decisions cannot overwrite each other. Leave PendingRequest
unchanged.

In code that hasn't changed since last review

Low severity Clarify 409 behavior under eventually consistent request reads

docs/​M3_ORG_LENS_API.md:211

This wording overstates the pending-only check: GetRequest reads eventually consistent data, and updateRequestStatus writes unconditionally (cla-backend-go/cla_manager/repository.go:285-292, 380-384). Given the accepted stale-read and concurrent-decision limits, document that 409 applies when the lookup observes a decided request, rather than promising it for every decided request. No change to the shared write behavior is needed for this documentation correction.
