Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change can still allow an invalidated ICLA to be re-signed in some cases and can record sanction audit events without an actual state transition. These are bounded but concrete correctness and audit-integrity risks, so the PR is not merge-ready until they are fixed or explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

- This checks only the signatures returned by
GetUserSignatures, whose default page size is 10 (signatures/service.go:268) and whose repository stops once that many matches are collected (signatures/repository.go:3124). An older invalidated ICLA beyond that page is therefore ignored, allowing the contributor to sign again despite #5154. Query explicitly for any signed/unapproved ICLA across all pages (for both normal and Gerrit callers) before proceeding.
if signature != nil && signature.SignatureSigned && !signature.SignatureApproved {
return true
cla-backend-go/v2/my_clas/service.go:1111
- This condition backfills
sanctioned_datewhen a legacy company is already sanctioned but has no date, making the first My CLAs page view appear to be the revocation time. #1370 explicitly requires no migration and says pre-M2 sanctions must remain undated because the actual transition time is unknown. Skip persistence for every already-sanctioned company; a cleared company remains eligible for a new timestamp becauseIsSanctionedis false.

docs/MY_CLAS_API.md:479
- The linked lfx-self-serve#1370 acceptance criteria are only partially implemented here. They require revocation timestamp/reason/actor on signature records and writes for both sanctions and CLA-manager removals; this PR exposes only the company-level
sanctioned_date, and no signature revocation fields or manager-removal writes are added. Implement the remaining contract or update the linked ticket/PR scope before treating #1370 as complete.
| `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; `flaggedAt` is omitted when no stored date exists (issue #1370: the revocation date) |
cla-backend-go/v2/sign/helpers.go:155
- The same non-atomic transition check occurs in the ECLA acknowledgement path: concurrent screens can both observe
false, restampsanctioned_date, and log duplicate sanction events. Emit only when an atomic repository update reports that this call performed false→true.
wasSanctioned := companyModel.IsSanctioned
cla-backend-go/v2/my_clas/service.go:1119
newSanctionis derived from a stale read, so concurrent My CLAs requests can both persist an SSS flag, movesanctioned_date, and emit duplicatecompany.sanctionedevents. Have the company update atomically distinguish a false→true transition and return whether this request applied it before setting the response date or logging.
newSanction := !companyModel.IsSanctioned
cla-backend-go/v2/sign/service.go:276
- This pre-read is not an atomic indication that this request created the sanction. Concurrent requests can both load
false;UpdateCompanySanctionStatusallows an already-SSS-sanctioned row (#O = :o), so both calls succeed, overwritesanctioned_date, and emit duplicatecompany.sanctionedevents. This also violates #1370's requirement that the revocation date be the momentis_sanctionedtransitions to true. Make persistence report whether a false→true transition actually occurred, and emit the event/date only for that caller.
wasSanctioned := comp.IsSanctioned
cla-backend-go/v2/sign/service.go:1267
- The same non-atomic transition check occurs here: two callbacks can both load
false, both accept the SSS update, and both restamp the revocation date/log the event. Use the persistence operation's atomic false→true result rather than the pre-write model value.
wasSanctioned := companyModel.IsSanctioned

cla-backend-go/swagger/common/my-cla.yaml:110
- This does not satisfy lfx-self-serve#1370's revocation contract: it exposes a company-level
sanctioned_date, but the issue requires additive revocation timestamp/reason/actor fields on signature records, including CLA-manager removals. Without those fields, revocation is not auditable per signature and cannot durably prevent later Approved-List revalidation. Please implement and expose the signature metadata, or unlink #1370 from this PR if that scope moved elsewhere.
description: The employer's stored sanctioned_date (the revocation date), stamped at the first live detection and refreshed when a cleared employer is flagged again; present only when flagged is true and a stored date exists
docs/MY_CLAS_API.md:408
- The claimed revoked date is still not stable.
checkCompanyCompliancein both signing backends callsUpdateCompanySanctionStatus(..., true, "sss")on every live flagged result, and that update rewritessanctioned_date; therefore later signing checks moveflaggedAt. #1370 defines the date as the false-to-true transition, so the persistence update must stamp it atomically only on that transition (while allowing a cleared company to receive a new date).
A failed write costs that employer only its stored date (the flag is then reported without a
date), and the listing never clears a flag. The first persist of a new sanction also logs a
`company.sanctioned` event.
cla-backend-go/swagger/cla.v2.yaml:3817
- Making the request body optional means PCC callers can still invalidate without any structured reason; the new bodyless test explicitly preserves that path. This conflicts with easycla#5153's acceptance criterion that a branchable reason is captured. Please require the body and
reasonfor the PCC invalidation operation, or provide a compatibility mechanism that cannot be used by the PCC path.
