Walkthrough

The changes update approval-list signature invalidation and ECLA reinvalidation, add corporate contributor identity fallback, return typed sanctioned-company callback responses, and add azp mode to the Auth0 token helper.

Changes

Signature record invalidation

Layer / File(s) Summary
Removal classification and conditional updates
cla-backend-go/signatures/dbmodels.go, cla-backend-go/signatures/repository.go, cla-backend-go/signatures/repository_test.go, cla-backend-go/signatures/approval_list_removal_test.go, cla-backend-go/signatures/employee_signature_test.go, cla-backend-go/signatures/mocks/mock_repo.go
The repository classifies approval-list removals and conditions removal and reinvalidation writes on signature state. Tests cover update expressions, removal classification, and concurrent changes.
ECLA reinvalidation flow
cla-backend-go/v2/signatures/service.go, cla-backend-go/v2/signatures/ecla_invalidate_test.go
ECLA invalidation selects reinvalidation for approval-list removal records. Tests cover legacy removal records, deliberate invalidations, and validation failures.

Corporate contributor identity

Layer / File(s) Summary
Contributor identity fallback
cla-backend-go/signatures/repository.go, cla-backend-go/signatures/corporate_contributors_test.go
Corporate contributor identity fields retain non-empty signature values and fall back individually to user-record values when missing.

Sanctioned-company callback response

Layer / File(s) Summary
Sanctioned-company callback response
cla-backend-go/v2/sign/service.go, cla-backend-go/v2/sign/handlers.go, cla-backend-go/v2/sign/handlers_test.go, cla-backend-go/swagger/cla.v2.yaml
The callback service returns a typed sanctioned-company error. The handler maps it to a 403 response, which the API specification documents.

Auth0 token helper modes

Layer / File(s) Summary
Token mode and credential selection
utils/get_auth0_token.sh, utils/auth0.secret.example, utils/test_get_auth0_token.py
The helper adds mode-specific settings and token files. In azp mode, it obtains credentials from configuration or the matching deployment. Tests cover mode settings and credential failures.
Token exchange and validation
utils/get_auth0_token.sh, utils/test_get_auth0_token.py
The helper conditionally sends a client secret and validates azp JWT claims. Tests cover token bindings, separate token files, and provider failures.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

What changed in this PR

Adds Auth0 AZP token support and updates EasyCLA invalidation, contributor identity, and sanctions handling.

Changes:

  • Adds AZP token generation, validation, configuration, and tests.
  • Updates ECLA invalidation and approval-list removal behavior.
  • Adds contributor identity fallbacks and typed sanctions responses.
File Summary / Findings
utils/​test_get_auth0_token.py Tests Auth0 token modes and failures.
utils/​get_auth0_token.sh Adds AZP token support. Moderate (1 vote): malformed JWT decoding can emit an uncontrolled traceback.
utils/​auth0.secret.example Documents AZP credentials.
cla-backend-go/​v2/​signatures/​service.go Supports deliberate ECLA re-invalidation.
cla-backend-go/​v2/​signatures/​ecla_invalidate_test.go Tests re-invalidation behavior.
cla-backend-go/​v2/​sign/​service.go Returns typed sanctions errors.

cla-backend-go/​signatures/​employee_signature_test.go Tests re-invalidation persistence.
cla-backend-go/​signatures/​dbmodels.go Detects approval-list removals. Moderate (1 vote): legacy-note detection is overly broad.
cla-backend-go/​signatures/​corporate_contributors_test.go Tests identity fallback behavior.
cla-backend-go/​signatures/​approval_list_removal_test.go Tests approval-removal safeguards.

Secret-scanning alert 53 is the public Auth0 prod client ID that has been on dev since c6ca13b (not a secret), but the next push reads all client IDs from gitignored *.secret files anyway; Copilot overview-only notes are not actionable (removal-write races are pre-existing and if_not_exists-guarded, the legacy-note match is intended, the malformed-JWT path is covered by try/except and a test).

Medium severity Avoid ordinary client file reads in AZP mode

utils/​get_auth0_token.sh:51

AZP mode still executes this ordinary-client file read before the mode branch replaces the value. As a result, get_auth0_token.sh dev azp fails if only the documented AZP client-ID file is present (and prod has the same dependency), even though AZP is meant to use its separate client. Select/read the client-ID file only after both stage and mode are known so each mode requires only its own file.

The Copilot overview's "previously missed" utils/get_auth0_token.sh:51 note is the same user-local-tool item already discarded above (pure literal→secret-file swap by design).

Note for reviewers: utils/*.sh (and their harness) are local-only helper scripts run by me on my machine, not deployed code - they do not need this level of repeated, verbose scrutiny; further review rounds should focus on cla-backend-go.

Medium severity Defer default client-ID file reads until mode and overrides are known

utils/​get_auth0_token.sh:51

This eagerly reads the ordinary dev client-ID file before mode selection and before the documented AUTH0_CLIENT_ID override is parsed. As a result, both a valid AZP-only setup and a non-AZP setup that supplies the override fail when this unused default file is absent. Defer reading the selected default until after the mode and credential overrides are known, then require a file only when no applicable override exists; the prod branch has the same problem.
