  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.

        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`.

        Authorized for the owning organization's current Carbon owner/admin

        bound to the internal Application UUID, the current Application
        If-Match version, and an Idempotency-Key. No request fields are needed;
        omit the body or send an empty JSON object.
        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
        application_webhook_no_pending_endpoint; non-verified Applications
        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.

            organization.invitations.read, organization.governance.read, and organization.tags.read,
            respectively. Tag/trust changes may include current.resource plus current.members.
            Raw trust configuration requires organization.trust.read. self.trust.read exposes only
            membership.effective_trust from the user's perspective, with target_silicon_membership_id,
            trust, and advisory, and no raw defaults, rules, overrides, or rule identifiers.
            Before-only recipients receive stable resource/version authorization tombstones, not
            removed private fields. Application payloads never include credentials or raw provider
            records, SSO events, or Silicon credential-management and webhook/subscription configuration.
            A completed Silicon credential rotation may expose only its permitted authorization-epoch
            and access projection. Silicon subscriptions retain their separate event vocabulary.
            Applications receive carbon.updated.v1 with scope-filtered fields;
            organization.membership.profile_updated.v1 is the organization-bound Silicon notification
            of that profile mutation, not a second Application event.
