Summary

The IdP now sends entraObjectId on each access-snapshot subject (PoliNetworkOrg/auth#84, implemented in PoliNetworkOrg/auth#86). This exposes it to consumers so the backend can tell which Microsoft 365 account a signed-in person is, and show a socio their own register entry and fee in My area (People Phase 2, PoliNetworkOrg/admin#144).

  • AccessSubject.entraObjectId: string | null: the Entra object ID (oid) of the PoliNetwork Microsoft 365 account, null when not linked or ambiguous.
  • The consumer schema accepts it as optional, so snapshots from older IdPs (including persisted ones) still parse, with null. An empty string is rejected.
  • AccessSubjectV1 (producer type), the snapshot-v1.json fixture and docs/contract.md document the field.

feat: → semantic-release publishes the next minor version on merge. The backend then bumps @polinetwork/auth-kit and reads snapshot.subjectBySub(actor.sub)?.entraObjectId.

Test plan

  • pnpm typecheck, pnpm test (97 passed), pnpm check
  • New tests: the field is read from the fixture, null when unlinked or from an older IdP, and an empty value is rejected

The IdP now sends `entraObjectId` on each snapshot subject: the Entra object
ID of the PoliNetwork Microsoft 365 account the person signs in with, or null
when there is none or the link is ambiguous (PoliNetworkOrg/auth#84). The
backend uses it to show a socio their own register entry and fee.

AccessSubject gains `entraObjectId: string | null`. The field is optional in
the consumer schema, so snapshots from older IdPs, including persisted ones,
still parse, with null.

Walkthrough

The snapshot subject contract and access index now include an Entra object ID. The consumer accepts an optional nullable field, while the producer type requires it. Missing values default to null, and duplicate non-null IDs are rejected. Fixtures, tests, and documentation cover the field.

Changes

Snapshot subject identity

Layer / File(s) Summary
Define and project the subject field
src/contract/snapshot.ts, src/snapshot/access-index.ts
The consumer schema accepts an optional, nullable entraObjectId, and the producer type requires it. AccessIndex.from defaults missing values to null and rejects duplicate non-null IDs.
Update examples and validation
fixtures/snapshot-v1.json, tests/snapshot.test.ts, docs/contract.md
The fixtures include null and populated object IDs. Tests cover present, missing, null, undefined, duplicate, and empty values. The contract documentation describes the field and its null cases.

46-46: Minor · Data Integrity & Integration · Low value

Validate entraObjectId as a GUID.

A snapshot containing "not-a-guid" passes validation and exposes that value to consumers, although the documented Microsoft oid is a GUID. Keep accepting null and omitted values.

Review comment at @src/contract/snapshot.ts at line 46:
Update the entraObjectId validator in the snapshot schema to accept only valid
GUID values when present, while continuing to accept null and omitted values;
use the schema library’s established GUID validation rather than a
non-empty-string check.
tests/snapshot.test.ts: 1

39-39: Trivial · Maintainability & Code Quality · Low value

Test missing IDs with roles present.

A parser that requires entraObjectId when roles are present could pass these tests while rejecting older snapshots. Add a case that removes only entraObjectId.

Suggested test

     expect(parseAccessSnapshot(withoutRoles(), "backend").bySub("usr_direttivo")?.entraObjectId).toBeNull()
+    const body = JSON.parse(fixture("snapshot-v1.json"))
+    for (const subject of body.subjects) delete subject.entraObjectId
+    expect(parseAccessSnapshot(JSON.stringify(body), "backend").bySub("usr_direttivo")?.entraObjectId).toBeNull()

- Line 91: Update the snapshot acceptance flow in access-index.ts to reject
snapshots where the same non-null Entra object ID is assigned to more than one
subject. Validate uniqueness before building or accepting the lookup index,
while allowing null IDs and preserving existing behavior for unique IDs.
