  title: Silicon IAM API
  version: 1.0.0
  summary: Secure identity, organization governance, application login, and delegated access.
  description: |
    Normative public and privileged HTTP contract for Silicon IAM. PostgreSQL is
    authoritative; webhook delivery never substitutes for online authorization.
    Timestamps are UTC RFC 3339 values. One-time secret responses can be replayed
    for ten minutes only by the same caller using the same route, request digest,
    and Idempotency-Key.
    IAM-managed six-digit OTPs expire after ten minutes. Signup, Carbon login,
    invitation-join, and verified-channel step-up challenges allow ten failed
    verifications, then enter a 60-second cooldown before the current unexpired
    challenge receives a fresh ten-attempt window. Replacement codes inherit
    the partial failed-attempt count or active cooldown.

    description: >-
      A testing environment is an organization-owned replica of Silicon IAM
      running against a separate database and starting completely empty. Every
      plane-selectable route accepts an `X-Testing-Environment-Key` header; supplying one
      executes that request inside the named environment instead of production,
      against the same contract. OTP delivery is suppressed and verification
      accepts `000000`. Test webhook deliveries are explicitly marked and
      carry their environment key. Organization-prefixed lifecycle routes in
      this section always operate on production; the singular test-only routes
      require the environment header.

        An authenticated direct Carbon submits the invited email. The service
        verifies that it is the exact active verified address immutably bound
        when that Carbon's invitation was created and that a pending unexpired
        invitation exists for this active email-join organization, then creates
        a pending challenge and sends the six-digit Postmark OTP outside the
        database transaction. The challenge becomes deliverable and the
        endpoint succeeds only after provider confirmation. The
        response exposes only the invitation ID needed by the join request and
        the code lifetime, never contact data. Ten attempts per Carbon and
        organization, including misses and varied emails, start a complete
        60-second cooldown. A successful idempotent replay does not consume an
        additional attempt.

      description: >-
        Deletes a tag. Requires `tags.manage`, which owners hold implicitly and
        admins by grant. The tag stops existing for every caller: it leaves
        listings and member projections immediately, stops conferring Silicon
        access, and its name becomes available again. The cascade is atomic --
        assignments are removed from every member who held it, tag-scoped trust
        rules are archived, and the affected members' authorization epochs
        advance so cached authority is invalidated at once. The removal is
        recorded in each affected member's tag history and published as
        `organization.tag_archived.v1`.

        bound to the internal Application UUID, the current Application
        If-Match version, and an Idempotency-Key. No request fields are needed;

        This narrow operation changes neither Application status nor scopes.
        A newly registered verified Application's first pending webhook is
        eligible; an Application itself still under_review requires platform
        application review. Missing pending endpoints return 409

        return 409 application_webhook_approval_state_conflict. Test endpoints
        normally activate immediately and therefore have no pending endpoint
        to approve. IAM revalidates the destination's public HTTPS/DNS safety
        at approval; an unsafe destination returns 422 without activation.

            Event-type-specific authorized projection; never contains credentials or raw provider records.
            For carbon.updated.v1, changed_fields and the complete current state are captured at the
            aggregate version and filtered per Application by its effective after-change profile, email,
            and phone consent scopes. The recipient union is authorized Applications immediately before
            or after the change, so a before-only recipient receives no fields it can no longer read.
            For the closed organization-member Application vocabulary (organization/ownership, tag,
            trust, membership/directory/authorization, and Silicon lifecycle or completed credential
            rotation events), recipient union, complete current state, and exact changed_fields are frozen
            in the domain transaction and filtered by profile, organizations.read, memberships.read,
            roles.read, and Carbon-only email/phone scopes. Member events always use
            current.members as an array; organization.updated uses current.organization and requires
            organizations.read; tag and trust events use current.resource plus current.members so their
            independently versioned aggregate is retained. Before-only recipients keep union-scope-filtered
            changed_fields but receive only stable resource/version authorization tombstones. Workers never
            hydrate these events from later state. An affected resource is an Application-readable principal
            or organization projection with an effective data scope; invitations, SSO/webhook configuration,
            administrative/protocol controls, and an unassigned tag creation have no Application projection.
            organization.membership.profile_updated.v1 and
            rotation-request, configuration, subscription, and protocol/control events are excluded from
            this Application projection vocabulary.
            organization.membership.profile_updated.v1 is the organization-bound Silicon projection of
            that mutation: it contains the changed non-contact profile fields, complete current membership
            state, and before/after affected tags captured at the same Carbon version.
