Review Change Stack

Walkthrough

Sanction dates now persist across company models, DynamoDB updates, live screening, legacy handlers, and API responses. Flagged responses use stored dates with fallback handling. Manager contact requests deduplicate email addresses while retaining selected manager usernames.

Changes

Sanction state lifecycle

Layer / File(s) Summary
Company sanction date contracts
cla-backend-go/company/models.go, cla-backend-go/company/projections.go, cla-backend-go/company/repository.go, cla-backend-go/swagger/common/*.yaml
Company storage, projections, conversions, and Swagger schemas now include sanctioned_date and sanctionedDate.
Sanction update persistence
cla-backend-go/company/repository.go, cla-backend-go/company/repository_test.go, cla-backend-legacy/internal/store/companies.go, cla-backend-legacy/internal/store/companies_test.go, utils/update_company_is_sanctioned.sh
Sanction updates now stamp dates, preserve dates when clearing flags, manage origins, and protect manual or admin sanctions from SSS overwrites.
Live screening and response timestamps
cla-backend-go/v2/my_clas/service.go, cla-backend-go/v2/my_clas/sanctions.go, cla-backend-go/v2/my_clas/service_test.go, cla-backend-go/v2/my_clas/cla_managers_test.go, docs/MY_CLAS_API.md
Live screening persists new SSS sanctions. Existing dates remain unchanged. Flagged responses use stored dates and fallback behavior. Tests and API documentation cover these rules.
Legacy sanction entrypoints
cla-backend-legacy/internal/api/handlers.go
Company creation and explicit sanction updates now record sanctioned_date.
Manager email recipient handling
cla-backend-go/v2/my_clas/service.go, cla-backend-go/v2/my_clas/cla_managers_test.go
Contact requests deduplicate email addresses case-insensitively while retaining all selected manager usernames.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 997d4

This PR adds sanctioned-date persistence and exposure, but the current head can remove an administrator’s sanction, mutate the wrong AWS account, or expose an unstable sanctioned timestamp. The safeguards and date semantics should be corrected before merge; the documentation also needs minor clarification.

cla-backend-go/v2/my_clas/service.go:1105

  • The first-detection stamp is not atomic. Two listings can both read the company as unflagged, and the shared repository condition permits an update when sanction_origin = sss (company/repository.go:1333), so the later request overwrites the earlier sanctioned_date; this call also returns no timestamp, so line 1113 invents a separate time that may not equal the stored value. Use a listing-specific conditional update that preserves an existing active stamp and returns the actual persisted date (reading the winning value after a conditional loss).
	if err := s.companyRepo.UpdateCompanySanctionStatus(ctx, companyModel.CompanyID, true, sanctionOriginSSS); err != nil {

cla-backend-go/v2/my_clas/service.go:1097

  • Existing sanctions are left without a durable date. Records flagged before this change necessarily have no sanctioned_date, and an administrator block is returned as stored without a live screen (sanctions.go:87-90), so this live-only path never stamps it; flaggedAt then falls back to the response time on every request. Backfill existing flagged rows or add a one-time stored-block stamp that preserves sanction_origin (for example, using an agreed fallback such as date_modified).
	if !state.flagged || state.check != models.MyClaFlaggedCheckLive || (companyModel.IsSanctioned && companyModel.SanctionedDate != "") {

cla-backend-go/swagger/common/my-cla.yaml:107

  • This API description is inconsistent with the implementation: the signing and legacy SSS flows call the shared update on every flagged result, and that update always rewrites sanctioned_date, so the stored value can be the latest detection rather than the first. Describe the field as the stored/last-set timestamp unless all writers are changed to preserve the initial date.
    description: The employer's stored sanctioned_date, stamped at the first live detection - the response time only when no date is stored and stamping it failed; present only when flagged is true

docs/MY_CLAS_API.md:478

  • The field reference promises a first-detection timestamp, but the signing and legacy flows explicitly restamp on every flagged result (as documented above at lines 403-405). Consequently this value can represent the most recent persisted flag-set, and response time is also used for pre-existing stored flags that have no date, not only failed writes.
| `flagged` / `flaggedAt` | bool / string | ECLA only: the employer is currently flagged by sanctions screening, and the company's stored `sanctioned_date` — stamped at the first live detection, so the response time only when no date is stored and stamping it failed |

cla-backend-go/v2/my_clas/service.go:1105

  • This does not atomically preserve a first-detection timestamp. The repository condition permits updates when sanction_origin is already sss, so concurrent requests or an eventually consistent stale read can overwrite sanctioned_date; it also swallows a concurrent manual-block condition failure as success. The operation should conditionally stamp one sanction episode and return whether it applied plus the actual persisted timestamp.
	if err := s.companyRepo.UpdateCompanySanctionStatus(ctx, companyModel.CompanyID, true, sanctionOriginSSS); err != nil {

cla-backend-go/v2/my_clas/service.go:1113

  • This generates a second timestamp after the repository has already written its own now, so flaggedAt is not guaranteed to equal the stored sanctioned_date (it can even cross a one-second boundary). Return the timestamp used by the update, or read back the stored value, instead of synthesizing another one.
	_, state.date = utils.CurrentTime()

cla-backend-go/swagger/common/company.yaml:53

  • The linked revocation-metadata acceptance criteria require timestamp plus reason/actor on each signature so revocation is durable per ECLA. A company-only sanctionedDate supplies neither per-signature state nor reason/actor, so it cannot back manager removals or keep an individual revoked signature excluded from later revalidation.
  sanctionedDate:
    type: string
    description: "When the sanction flag was last set; kept after it is cleared"
    example: "2026-08-20T10:11:12Z"

cla-backend-go/swagger/common/my-cla.yaml:107

  • This public description says the date is stamped at the first live detection, but both signing paths call UpdateCompanySanctionStatus(..., true, "sss"), which unconditionally replaces sanctioned_date on every flagged result. Either preserve the first timestamp in those paths or describe this as the most recent sanction-status set.
    description: The employer's stored sanctioned_date, stamped at the first live detection - the response time only when no date is stored and stamping it failed; present only when flagged is true

docs/MY_CLAS_API.md:478

  • This field reference also promises a first-detection timestamp, while the signing and legacy SSS paths intentionally restamp on every flagged result (as the paragraph above notes). Align the field contract with the actual last-set semantics unless those writers are changed to preserve the first timestamp.
| `flagged` / `flaggedAt` | bool / string | ECLA only: the employer is currently flagged by sanctions screening, and the company's stored `sanctioned_date` — stamped at the first live detection, so the response time only when no date is stored and stamping it failed |
