Part of #122: everything but retiring azure.members.create and azure.members.setAssocNumber, which waits for the dashboard to switch (PoliNetworkOrg/admin#155). Design: docs/people/soci.md. The permissions are already in the production IdP (PoliNetworkOrg/auth#85).

Data

Migration 0033_soci_register adds three tables. None of them is ever deleted from.

• soci_members: one row per admission.
  • Keyed on number and entra_object_id, both unique.
  • Snapshots of the mailbox and display name.
  • Legal name and an optional alias.
  • Codice fiscale, birth date and place, and residence (the province only in Italy).
  • admitted_on, plus the end and account-state columns that the lapse issue ([People · Phase 2] End a socio's status, automatic lapse and account deletion #124) will set.
• soci_numbers: every number a record has ever held. Its primary key is what makes "never reused" hold at the database level, also after setNumber.
• soci_activity: append-only history.
• Constraints: a partial unique index allows only one active record per codice fiscale. Checks keep the end date and reason together and match the account state to its deletion date.

Procedures (soci.members.*)

Procedure	Policy
list, get, unregistered	admin:access + soci:read
admit, register, update, setNumber	admin:access + soci:write

The policy carries the soci:* permission, so the router walk shows it. A middleware also requires admin:access.

• admit:
  • Runs today's Microsoft 365 create workflow (account with employeeId, licences, Soci group, cleanup on failure), then writes the record. Every detail is required except the alias.
  • If the record can't be written, the account is deleted and the number stays free. If that deletion also fails, the call says to contact IT and the number stays reserved.
  • The welcome email goes to the typed address, which isn't stored.
• register: writes a record for an account already in Soci, with its current number. Only the legal name is required. An account without an employeeId gets the number given, if it's free. A number other than the account's is refused.
• list: each row has inSoci and mismatch (not_in_soci for an active record, still_in_soci for an ended one). If Graph can't be read, it still answers, with directoryAvailable: false.
• get: the record, its activity and the account's current employeeId.
• unregistered: Soci group members without a record, with employeeId and createdDateTime (the suggested admission date).
• update: replaces the details and the admission date, and logs which fields changed.
• setNumber: changes the number on the account and on the record, optionally emailing it as today. If the record write fails, the account goes back to its old number.
• Numbers: a number is free only if no record has ever held it and no Microsoft 365 user has it as employeeId. A record may go back to a number it held itself. Writes share serializeMemberWrite and the pending-number cache with azure.members.*.
• Codice fiscale:
  • Normalized, then validated: format, omocodia letters, check character, and a day that exists.
  • Checked against the birth date.
  • A code held by an active socio is refused. A former socio's code is allowed, and list rows carry the code so the dashboard can warn.

Directory (Graph + mock)

• getSociMembers() reads the Soci group, including createdDateTime.
• addToSoci, removeFromSoci and deleteUser are idempotent, for the lapse issue. createMember's cleanup now uses deleteUser.
• The mock directory implements all four and keeps the group in sync with isMember.

npm package

Exports the soci contract types: SociList, SocioRow, SocioRecord, SocioDetails, SociUnregistered and the inputs and results.

Tests

• tests/soci.test.ts:
  • codice fiscale validation, including omocodia, women's days and the birth-date match;
  • refusing a reused number: from a record, from an ended record, from a number changed away, and an Entra-only one;
  • refusing two active records with one code, while a former socio's code is allowed;
  • a failed record write deleting the new account (and the double-failure message);
  • register for an existing Soci account (with and without a number);
  • mismatches, and the register when Graph is down;
  • update and setNumber, including the rollback.
• tests/soci-router.test.ts: policies, admin:access, input validation before Microsoft 365, and the author taken from the token.
• tests/soci-postgres.test.ts: round-trip and constraints in real PostgreSQL.

Validation:

• bun run check, bun run typecheck and bun run build:npm pass.
• vitest run gives 344 passed and 2 skipped, with a disposable PostgreSQL.

Walkthrough

The pull request adds a Soci register backed by PostgreSQL and Microsoft 365 group membership. It adds validation contracts, register operations, protected router procedures, directory integrations, and tests for persistence, authorization, and service workflows.

Soci Register

Layer / File(s)	Summary
Register contracts and schema src/soci/contract.ts, src/soci/codice-fiscale.ts, src/soci/types.ts, src/db/schema/soci/index.ts, drizzle/0033_soci_register.sql, drizzle/meta/_journal.json, src/db/schema/create-table.ts, src/db/schema/index.ts, src/index.ts, tests/soci.test.ts	Defines request and response schemas, codice fiscale validation, Soci member and activity tables, number-assignment records, uniqueness and state constraints, and exported types.
Microsoft 365 directory operations src/azure/types.ts, src/azure/functions/members.ts, src/azure/directory.ts, src/azure/mock-directory.ts	Adds Soci group listing and membership operations, user deletion, creation timestamps in the mock directory, and failed-account-creation cleanup through the shared deletion helper.
PostgreSQL store src/soci/store-pg.ts, tests/soci-postgres.fixture.ts, tests/soci-postgres.test.ts	Adds PostgreSQL record queries and transactional writes for members, number assignments, and activity. The integration fixture checks persistence and uniqueness behavior.
Register service workflows src/soci/service.ts, tests/soci-fixtures.ts, tests/soci.test.ts	Implements member listing, admission, registration, updates, and number changes. The service coordinates directory operations and record persistence, and handles cleanup, rollback, and email outcomes.
Protected router and application wiring src/soci/router.ts, src/soci/index.ts, src/routers/soci.ts, src/routers/index.ts, tests/soci-router.test.ts, tests/idp-router.test.ts, README.md	Adds the Soci router with read and write permissions plus an admin:access check. Registers the router in the application and documents the register operations and permissions.

Change: Feature

Merge Risk: Low · previous review f0c26

If a number change fails to save and the attempt to restore the old number in Microsoft 365 also fails, the operator is told the account kept its old number when it did not. The register and Microsoft 365 then disagree without any signal. This is a narrow failure-path issue with a small fix. The rest of the Soci register change looks sound.

- Around line 401-407: Update the rollback around directory.setMemberNumber so
both a returned error and a thrown error are treated as restore failures; log
the failure with the actor and member context, then report that Microsoft 365
may still have input.newNumber and instruct the operator to contact IT. When
restoration succeeds, preserve the existing writes.rememberNumber behavior and
message that the account keeps the old number.
