Randall Stillwell 820dae6510 docs(plans): split workspace-invites convoy into identity + invites + autocomplete
User pushed back on "strict email match in v1" — the right architectural
answer is multi-email identity (one users row owning multiple verified
emails), not a stopgap. Scaling the convoy accordingly:

1. Task-multi-email-identity (NEW, P1, foundation)
   - user_email_identities table (user_id, email lowercased, verified_at,
     source: primary | oauth:<provider> | manual)
   - Refactor ensureUserIdByEmail -> ensureUserIdByVerifiedEmail against
     the new table.
   - OAuth callback writes a source='oauth:<provider>' identity when the
     provider returns email_verified=true. Cross-user conflict rejects.
   - Profile UI: "Linked emails" section, read-only in v1.
   - Exports userOwnsEmail(userId, emailLower) for invite accept to call.

2. Task-workspace-invites-and-roles (existing, narrowed)
   - All the original spec.
   - Accept procedure calls userOwnsEmail() instead of comparing
     users.email directly. Mismatch renders an explainer page, not a
     silent accept.

3. Task-invite-recipient-autocomplete (NEW, P1, polish)
   - invites.suggestRecipient returns typed suggestions across four
     kinds: member / pending_invite / known_user / new_email.
   - Tenancy fence on known_user is the security-relevant assertion;
     test for it explicitly.
   - Combobox UI renders each kind with its own affordance.

Three follow-ups filed explicitly to keep this convoy PR-sized:
- Task-manual-email-verification (add an email outside OAuth)
- Task-disconnect-linked-email (destructive, needs last-verified guard)
- Task-account-merge (handle the legacy duplicate-users case)

Epic file refreshed with the new task table, follow-up table, and a
phase ordering note. Identity lands first because it touches the
sign-in path; invites and autocomplete can ship in their own PRs.

task disconnect-linked-email Disconnect a linked email from a user's profile multitenant-saas-hardening tenant-lifecycle draft P2 global unassigned null 2026-06-02

Task summary

Let a user remove a linked email from their profile. Sounds simple; isn't. Removing the wrong row can either lock the user out (no verified email = can't be matched on next sign-in) or strand an invite that was bound to that email.

Why deferred from the invites convoy

Task-multi-email-identity ships the "Linked emails" list as read-only. Adding a remove action requires:

  • Server-side guard: cannot remove the user's last verified identity. Cannot remove the source='primary' identity unless another verified identity is promoted to primary in the same transaction.
  • UX for the "this email has 2 pending workspace invites — accept or revoke them first" case.
  • Audit-log entry (overlaps with Task-workspace-soft-delete-and-audit).
  • Confirmation modal with clear "this will affect: pending invites X, Y" copy.

Scope (sketch — refine when scheduled)

  • identity.disconnectEmail({ identityId }) procedure with the guards above.
  • Profile UI: confirmation modal that lists pending-invite impact before the destructive action.
  • If the disconnected identity was source='primary', prompt to choose a new primary from the remaining verified set.

Acceptance criteria (draft)

  • Cannot disconnect the only verified identity on an account.
  • Disconnecting an email that has pending invites surfaces those invites in the confirmation flow.
  • Audit-log row written for every disconnect.
  • Epic: ./Epic-tenant-lifecycle.md
  • Depends on: ./Task-multi-email-identity.md, ./Task-workspace-soft-delete-and-audit.md (for audit log).
