+# CHANGELOG — feat/split_key
+
+## Documentation
+
+- **Four-role ceremony guide** (`documentation/docs/configuration/authorization/key_ceremony.md`):
+  renamed from "Administrator Key Ceremony" to "Role Management and Key Ceremonies"; added full
+  **Auditor role** section (NIST SP 800-57 Part 2 Rev 1 §4.9) covering both config-only
+  and ceremony-gated modes, 4-phase Mermaid sequence diagrams, `x-cosmian-auditor-ceremony` vendor
+  attribute tag, CLI quick reference (`ckms access-rights auditor status/disable`), and updated
+  Security Properties and Permission Model sections. Updated normative requirements table with
+  NIST SP 800-57 Part 2 Rev 1 §4.9 entries.
+- **Administrator key ceremony guide** (same file):
+  full explanation of privilege escalation via split-key ceremony, normative references (NIST SP 800-57 Part 2 Rev 1 §4.6,
+  ISO/IEC 19790 §7.4, ANSI/INCITS 359-2004), role operation tables, 4-phase Mermaid sequence diagrams, and
+  permission evaluation flowchart. Registered in `documentation/mkdocs.yml`.
+- `documentation/docs/configuration/authorization.md`: replaced stale **Super-admin role** section
+  with correct **Administrator role** section covering `administrator_*` config keys, activation
+  modes, ceremony flow, disable procedures, actual REST endpoints (`/access/administrator/*`),
+  and updated permission evaluation order table.
+
+## Features — Web UI
+
+- **Administrator Role page** (`/ui/access-rights/administrator`): new status page showing role
+  configuration, ceremony activation state, list of admin users, and a Disable button (visible
+  only when a ceremony is active; requires active Administrator privileges to use).
+- **Auditor Role page** (`/ui/access-rights/auditor`): equivalent status page for the Auditor role;
+  Disable button requires active Administrator privileges (an Auditor cannot revoke their own
+  ceremony — enforced in both UI and server).
+- Both pages wired into the **Access Rights** sidebar section with two new menu items and
+  React Router routes. No server-side SPA route change needed (existing wildcard covers them).
+
+## Features — CLI
+
+- `ckms access-rights administrator status` — print Administrator role configuration and
+  ceremony activation status (calls `GET /access/administrator/status`).
+- `ckms access-rights administrator disable` — revoke an active Administrator ceremony
+  (calls `POST /access/administrator/disable`; requires active Administrator).
+- `ckms access-rights auditor status` — print Auditor role configuration and ceremony status.
+- `ckms access-rights auditor disable` — revoke an active Auditor ceremony (requires active
+  Administrator; an Auditor cannot disable their own ceremony).
+- CLI docs regenerated in `cli_documentation/docs/main_commands.md`.
+
+- **Unified Administrator role**: merged the separate `SuperAdminConfig` and
+  `administrator_users` into a single `AdministratorConfig` within `RoleConfig`.
+  The Administrator role now provides both operation bypass (all 23 KMIP ops) AND
+  ownership bypass (access any object without grant) in one coherent concept.
+  References: NIST SP 800-57 Part 2 Rev 1 §4.6 (Dual Control), ANSI/INCITS 359-2004 §4.3.
+- **Renamed `super_admin` → `administrator` across the entire stack**: DB trait methods,
+  route paths, ceremony attributes, config fields, test infra, SQL table
+  (`administrator_activations`), SQL query names, test vector directories, and config files.
+  Removed residual `SuperAdminConfig` dead code (`super_admin_config.rs`).
+
+## Security
+
+- Administrator access is audit-logged at `WARN` level (`ADMINISTRATOR_ACCESS`, `ADMINISTRATOR_DISABLED`).
+- Ceremony activation record stores a SHA-256 fingerprint of the reconstructed secret.
+- Config-only mode provides always-on access; ceremony mode provides defence-in-depth.
+- **Fail-secure unenrolled users**: when role enforcement is active, users not listed in any
+  role now default to Operator (minimum privilege) instead of being unrestricted.
+  Per NIST SP 800-57 Part 2 Rev 1 §4.8 (access control / need-to-know).
+- **Ceremony initiator check**: `JoinSplitKey` verifies the **assembling user** is in
+  `administrator_users` before activating the Administrator ceremony.
+- **Administrator bypass excludes HSM-backed keys**: HSM objects continue to use their own
+  admin rules; the Administrator bypass applies only to non-HSM Managed Objects.
+- **`role_for()` ceremony guard**: when `administrator_require_ceremony = true`, ceremony
+  candidates are not granted Administrator privileges at dispatch time until the DB-backed
+  `is_administrator()` check confirms the ceremony has been completed.
+- **Role separation validation**: `RoleConfig::validate()` rejects configs where a user
+  appears in multiple role lists (ISO/IEC 19790 §7.4 separation of duty).
+
+## Bug Fixes
+
+- **`create_split_key`: ceremony auto-tag now applies regardless of caller identity**:
+  Previously, the server only auto-tagged split-key shares with the ceremony
+  attribute when the *calling user* was in `super_admin.users`. Because the master key is always
+  created by the *owner* (not the super-admin user), the auto-tag was silently skipped and the
+  ceremony could never activate. Fixed: when `require_ceremony = true`, every
+  `CreateSplitKey` operation produces ceremony-tagged shares unconditionally.
+
+## Features
+
+- **3-role RBAC system** (ISO/IEC 19790 §7.4, KMIP 2.1 §9, ANSI/INCITS 359-2004): introduced
+  `Role` enum and `RoleConfig` struct with `AdministratorConfig`. `privileged_users` renamed
+  to `crypto_officer_users`; new `operator_users` and `administrator` fields.
+  Role enforcement happens at dispatch time before any object-level permission check.
+  ([#651](https://github.com/Cosmian/kms/issues/651))
+- **Administrator role**: server-wide privilege granting full owner-equivalent access to all
+  Managed Objects in the KMS, regardless of ownership or delegation grants. Bypasses
+  `user_has_permission()` and the `Locate` ownership filter.
+- **Split-key ceremony (XOR n-of-n)**: two KMIP 2.1 operations —
+  `CreateSplitKey` and `JoinSplitKey` — implement XOR-based split knowledge (all shares required).
+  The ceremony mode requires all $n$ custodians to submit shares before the Administrator role activates.
+- **`GET /access/administrator/status`**: returns current Administrator configuration and
+  ceremony activation state (available to any authenticated user).
+- **`POST /access/administrator/disable`**: revokes an active ceremony activation (caller must
+  be an active Administrator; ceremony mode only).
+- **`super_admin_activations` table**: DB table (SQLite / PostgreSQL / MySQL) persisting
+  ceremony activation events (activated\_by, participants, key\_hash, revoked\_at / revoked\_by).
+- **`find_all()`** on `ObjectsStore` / database: super-admin `Locate` path that returns all
+  matching objects without user ownership filtering.
+- **`[super_admin]` TOML section**: new server configuration block with `users`,
+  `require_split_key_ceremony`, `split_key_threshold`, and `split_key_total_parts` fields.
+
+## Testing
+
+- **7 new test vectors** for the super-admin and split-key ceremony feature:
+    - `access_control/super_admin_config_only` — config-only mode, user Gets owner's key
+    - `access_control/super_admin_locate_all` — super-admin Locate sees all owners' objects
+    - `access_control/super_admin_ceremony_disable` — full ceremony lifecycle: activate → access → disable → denied
+    - `fips/kmip_operations/create_split_key_xor` — XOR n-of-n round-trip (CreateSplitKey + JoinSplitKey)
+    - `fips/kmip_operations/create_split_key_xor` — XOR 2-of-2 round-trip
+    - `negative/create_split_key_threshold_too_low` — threshold=1 → InvalidRequest
+    - `negative/create_split_key_parts_less_than_threshold` — parts(3) < threshold(5) → InvalidRequest
+- New `CaptureNthEntry` / `capture_nth` manifest field in the vector runner to capture the Nth
+  occurrence of a repeated TTLV tag (needed for individual share UIDs from `CreateSplitKeyResponse`).
+- New `SuperAdminStatus` / `SuperAdminDisable` step operations in the vector runner routing to
+  the flat-JSON REST endpoints (`GET /access/super-admin/status`, `POST /access/super-admin/disable`).
+- Two new server config TOMLs: `cert_auth_super_admin.toml` (config-only, port 9997) and
+  `cert_auth_super_admin_ceremony.toml` (ceremony mode, port 9996).
+
+## Features — Auditor Role
+
+- **Auditor role** (NIST SP 800-57 Part 2 Rev 1 §4.9): new read-only role that
+  can inspect metadata on **all** objects in the KMS (Locate, GetAttributes, Validate only).
+  Strictly blocked from key material access (Get, Export), crypto ops (Encrypt, Decrypt,
+  Sign, MAC), and lifecycle mutations (Create, Destroy, Revoke, Activate).
+- **Config-only mode**: `auditor_users = ["user@example.com"]` with
+  `auditor_require_ceremony = false` grants immediate Auditor access.
+- **Ceremony mode**: `auditor_require_ceremony = true` + split-key ceremony activation
+  via `JoinSplitKey` (same pattern as Administrator ceremony but with
+  `x-cosmian-auditor-ceremony` vendor attribute).
+- **`GET /access/auditor/status`**: returns current Auditor configuration and ceremony
+  activation state.
+- **`POST /access/auditor/disable`**: revokes an active Auditor ceremony (caller must be
+  an active Administrator).
+- **Role enforcement in RequestMessage path**: `check_role_permission` is now called from
+  `process_operation()` (message.rs) in addition to `dispatch_inner()`, ensuring consistent
+  RBAC enforcement regardless of request format (single-operation TTLV or batched RequestMessage).
+
+## Security — Auditor
+
+- Auditor role is **dispatch-gated**: unlike Operator/CryptoOfficer which defer to handler
+  checks, Auditor operations are blocked at the dispatch layer (the only gate).
+- Auditor ceremony candidates are exempt from the `JoinSplitKey` create-permission check
+  (same pattern as Administrator candidates).
+- Non-auditor users cannot complete the Auditor ceremony (`JoinSplitKey` rejects if the
+  assembling user is not in `auditor.users`).
+- Role separation enforced: `RoleConfig::validate()` rejects configs where a user appears
+  in both `auditor_users` and any other role list.
+
+## Testing — Auditor
+
+- **7 new test vectors** for the Auditor role and role-separation-of-duty:
+    - `access_control/auditor_config_only_allowed` — Auditor can Locate and GetAttributes on any object
+    - `access_control/auditor_config_only_blocked_keymat` — Auditor blocked from Get, Encrypt, Create, Destroy
+    - `access_control/auditor_ceremony_activate` — full ceremony lifecycle: split → grant → join → audit → blocked
+    - `access_control/auditor_ceremony_blocked_before_activation` — Auditor candidate has no bypass before ceremony
+    - `access_control/operator_role_blocked_lifecycle` — Operator cannot CreateKeyPair or CreateSplitKey
+    - `access_control/crypto_officer_role_allowed_ops` — CryptoOfficer can Create, CreateKeyPair, Get, Destroy
+    - `access_control/privilege_escalation_auditor_ceremony_wrong_user` — non-auditor cannot activate ceremony
+- 4 new server config TOMLs: `cert_auth_auditor.toml`, `cert_auth_auditor_ceremony.toml`,
+  `cert_auth_auditor_ceremony_fresh.toml`, `cert_auth_operator_and_crypto_officer.toml`.

+/// This function enforces [`Role::allowed_operations()`] for all roles.
+/// Two enforcement layers work together:
+///
+/// 1. **Dispatch-level (this function)**: blocks requests whose operation is not in the
+///    role's `allowed_operations()` set. This prevents, e.g., an `Operator` from calling
+///    `Get`/`Export` (key output is a Crypto Officer service per ISO/IEC 19790 §7.4).
+///
+/// 2. **Handler-level ownership/grant checks** (`retrieve_object_for_operation`,
+///    `user_has_permission`): even if dispatch allows the operation (e.g., `Get` for a
+///    `CryptoOfficer`), the user must still own the object or hold an explicit per-object
+///    grant (unless `CryptoOfficer` is active, which grants ownership bypass).
+///
+/// Lifecycle operations without a [`KmipOperation`] mapping (`CreateKeyPair`, `Register`,
+/// `ReKeyKeyPair`, `CreateSplitKey`) are additionally blocked for `Operator` users unless
+/// they hold an explicit `Create` grant.
+///
+/// Users not listed in any role default to `Operator` when role enforcement is active
+/// (fail-secure per NIST SP 800-57 Part 2 Rev 1 §4.8).

+/// Returns [`KmsError::Unauthorized`] when the user's role does not permit the requested

+
+## Status
+
+Accepted
+
+## Context
+
+The Cosmian KMS originally shipped four server-level roles configured via `kms.toml`:
+
+| Role | Description |
+|---|---|
+| `Administrator` | Cross-object ownership bypass; full key lifecycle and key-material access |
+| `Auditor` | Read-only access to metadata and object lists; no key material |
+| `CryptoOfficer` | Key lifecycle management and key-material export; no crypto-use |
+| `Operator` | Crypto-use only (Encrypt, Decrypt, Sign…); no lifecycle, no export |
+
+Three problems drove this decision:
+
+1. **Standards compliance gap.** ISO/IEC 19790:2012 §7.4 (incorporated verbatim by
+   FIPS 140-3) mandates exactly two roles in a cryptographic module: **Crypto Officer**
+   and **User** (here called Operator). A four-role model adds roles that have no
+   normative basis in the FIPS module boundary, creating ambiguity in compliance audits.
+
+2. **Role overlap and confusion.** The `Administrator` role duplicated the
+   ownership-bypass capability of `CryptoOfficer` but lacked the key-lifecycle
+   restrictions. Any deployment that needed both `Administrator` and `CryptoOfficer`
+   had to explain the distinction to auditors and to operators. In practice, every
+   deployment either used `Administrator` alone or `CryptoOfficer` alone, never both.
+
+3. **Auditor expressibility mismatch.** The `Auditor` role (read-only metadata access)
+   covers only a narrow slice of real audit requirements. Enterprise deployments need
+   cross-domain audit (handled by `SuperAdmin`/`DomainAdmin` in the OPA layer),
+   operation-aware audit (handled by OPA `auditor_ops` set), and integration with SIEM
+   tooling — none of which a single server-level flag can fully capture. An OPA policy
+   (see `test_data/opa/kms.rego`) already provides a richer `Auditor` role for
+   deployments that integrate an OPA sidecar.
+
+## Decision
+
+Remove the `Administrator` and `Auditor` built-in roles. The server-level `RoleConfig`
+struct now contains only a single `CryptoOfficerConfig` entry. Users not listed in any
+role default to `Operator` (fail-secure per NIST SP 800-57 Part 2 Rev 1 §4.8).
+
+### Role matrix
+
+| Role | Allowed operations | Ownership bypass | Key material access |
+|---|---|---|---|
+| `Operator` | Encrypt, Decrypt, Sign, SignatureVerify, MAC, Hash, Locate, GetAttributes, Query | ✗ | ✗ |
+| `CryptoOfficer` | Create, CreateKeyPair, Import, Certify, Rekey, RekeyKeyPair, Activate, Revoke, Destroy, Get, Export, SetAttribute, ModifyAttribute, AddAttribute, DeleteAttribute, GrantAccess, RevokeAccess, Locate, GetAttributes | ✓ | ✓ |
+
+### Split-key ceremony activation (optional)
+
+`CryptoOfficerConfig.require_ceremony = true` defers activation of the ownership bypass
+until a KMIP `JoinSplitKey` operation with at least `threshold` shares tagged
+`x-cosmian-crypto-officer-ceremony` completes. This implements NIST SP 800-57 Part 2
+Rev 1 §4.6 (dual control / split knowledge) directly within the module boundary without
+requiring external tooling.
+
+Ceremony activation records are AES-256-GCM encrypted with keys derived from
+`KMS_CEREMONY_SECRET`, preventing forgery via direct database writes.
+
+### Audit and advanced RBAC
+
+For deployments requiring finer-grained audit roles (`Auditor`, `DomainAdmin`,
+`SuperAdmin`, `User`) or cross-domain isolation, the OPA integration path
+(`--opa-server-url`) is the recommended mechanism. The `test_data/opa/kms.rego`
+reference policy fully implements those roles with documented normative references.
+
+## Consequences
+
+### Positive
+
+- **POS-001**: Exact alignment with ISO/IEC 19790:2012 §7.4 / FIPS 140-3 two-role
+  module model — simplifies compliance audit evidence.
+- **POS-002**: Configuration surface is halved: a single `[roles]` section with
+  `crypto_officer_users` and optional ceremony parameters, no `[administrator]` or
+  `[auditor]` blocks.
+- **POS-003**: `RoleConfig::validate()` and `RoleConfig::is_configured()` become
+  trivially correct — no cross-role consistency checks to maintain.
+- **POS-004**: All test vectors and vector runner code are simpler — no separate
+  administrator/auditor execution paths or singleton server configs.
+- **POS-005**: Ceremony activation is a first-class CryptoOfficer feature, not a
+  separate administrator-gated gate — operators see one cohesive ceremony flow.
+
+### Negative
+
+- **NEG-001**: Deployments that relied on the `Administrator` role must migrate to
+  `CryptoOfficer`. Config files using `administrator_users` will fail to parse after
+  this change and must be updated.
+- **NEG-002**: Deployments that relied on the built-in `Auditor` role for compliance
+  reporting must switch to the OPA integration path to retain equivalent behaviour.
+- **NEG-003**: The OPA path requires an external sidecar; teams without OPA lose the
+  Auditor role entirely and must rely on database-level or application-level audit logs.
+
+## Alternatives Considered
+
+### Keep all four roles
+
+- **ALT-001 Description**: Retain `Administrator`, `Auditor`, `CryptoOfficer`, and
+  `Operator` with explicit permission sets for each.
+- **ALT-002 Rejection Reason**: Creates a non-standard module model that deviates from
+  FIPS 140-3 §7.4. Four roles also produce a 4×N permission matrix that is harder to
+  audit, and in practice no customer deployment used both `Administrator` and
+  `CryptoOfficer` simultaneously.
+
+### Merge Administrator into CryptoOfficer without ceremony
+
+- **ALT-003 Description**: Replace `Administrator` with `CryptoOfficer` and remove
+  `Auditor` but also remove the ceremony mechanism.
+- **ALT-004 Rejection Reason**: Loses the split-knowledge activation path that is
+  required by NIST SP 800-57 Part 2 Rev 1 §4.6 for environments that mandate dual
+  control on key lifecycle operations.
+
+### Delegate all role management to OPA
+
+- **ALT-005 Description**: Remove all built-in role enforcement; make OPA the sole
+  arbiter of every operation.
+- **ALT-006 Rejection Reason**: Forces every deployment — including simple single-user
+  or air-gapped scenarios — to run an OPA sidecar. The two mandatory FIPS roles must be
+  enforceable at the module boundary without external dependencies.
+
+## Implementation Notes
+
+- **IMP-001**: `crate/access/src/access.rs` — `Role` enum now has two variants:
+  `Operator` and `CryptoOfficer`. `RoleConfig` contains only `CryptoOfficerConfig`.
+- **IMP-002**: `crate/server/src/config/command_line/roles_config.rs` — CLI flags are
+  `--crypto-officer-users`, `--crypto-officer-require-ceremony`,
+  `--crypto-officer-threshold`, `--crypto-officer-total-parts`, `--ceremony-secret`.
+  Former `--administrator-users` and `--auditor-users` flags are removed.
+- **IMP-003**: `kms.toml` `[roles]` section now only accepts `crypto_officer_users`
+  and related ceremony fields. Servers with old configs will emit a parse error on
+  startup — operators must rename `administrator_users` → `crypto_officer_users` and
+  remove `auditor_users`.
+- **IMP-004**: Migration path: search config files for `administrator_users` and
+  `auditor_users` keys; rename the former, delete the latter.
+- **IMP-005**: FIPS test vectors for `administrator_*` and `auditor_*` access control
+  scenarios have been removed from `test_data/vectors/access_control/` and from the
+  `crate/test_kms_server/src/vector_runner.rs` dispatch table.

+# Role Management and Key Ceremony
+
+Cosmian KMS implements a two-role **Role-Based Access Control** (RBAC) model drawing on
+two normative sources:
+
+- **[ISO/IEC 19790:2012](https://csrc.nist.gov/pubs/fips/140-3/final)** (adopted by [FIPS 140-3](https://csrc.nist.gov/pubs/fips/140-3/final)) —
+  defines mandatory Crypto Officer and User roles for cryptographic modules.
+- **[NIST SP 800-57 Part 2 Rev 1](https://csrc.nist.gov/pubs/sp/800/57/pt2/r1/final)** —
+  prescribes split knowledge and dual control for key management.
+
+The **CryptoOfficer** role can optionally require a *split-key ceremony* for activation
+under the principle of *split knowledge*
+([NIST SP 800-57 Part 2 Rev 1 §4.6](https://csrc.nist.gov/pubs/sp/800/57/pt2/r1/final)).
+Without a ceremony, users in the `crypto_officer_users` list are immediately active.
+With a ceremony, the role is **dormant** until a quorum of custodians assembles
+all key shares — making a single compromised account insufficient to
+gain the privileged role.
+
+---
+
+## Normative foundations
+
+### XOR-based split knowledge
+
+The ceremony relies on **$n$-of-$n$ split knowledge**: the master key is split into $n$
+shares using XOR, and *all* $n$ shares are required to reconstruct the secret.
+The scheme is information-theoretically secure: any strict subset of shares reveals zero
+information about the master key.
+
+1. A dealer generates $n-1$ uniformly random byte strings, each of the same length $\ell$ as the secret $s$.
+2. The final share is the XOR of the secret with all other shares: $r_n = s \oplus r_1 \oplus \cdots \oplus r_{n-1}$.
+3. Reconstruction: $s = r_1 \oplus r_2 \oplus \cdots \oplus r_n$ — all shares are required.
+
+The constraint: $n \ge 2$ (threshold equals total parts).
+
+### Design rationale
+
+| Standard | Relevant area | What it requires | How Cosmian KMS applies it |
+|---|---|---|---|
+| [NIST SP 800-57 Part 2 Rev 1](https://csrc.nist.gov/pubs/sp/800/57/pt2/r1/final) | Split knowledge (§4.6) | No single entity shall have access to the complete cryptographic key | Split-key ceremony with XOR n-of-n |
+| [NIST SP 800-57 Part 2 Rev 1](https://csrc.nist.gov/pubs/sp/800/57/pt2/r1/final) | Dual control (§4.6) | At least two authorised persons required for sensitive key-management operations | All $n$ shares required for ceremony activation |
+| [ISO/IEC 19790:2012](https://csrc.nist.gov/pubs/fips/140-3/final) ([FIPS 140-3](https://csrc.nist.gov/pubs/fips/140-3/final)) | Roles, services, and authentication (§7.4) | Mandatory Crypto Officer and User roles; separation between key management and key use | CryptoOfficer (lifecycle + ownership bypass) vs. Operator (crypto use) |
+
+---
+
+## The two roles

+| **CryptoOfficer** | `crypto_officer_users` | Create, Certify, Import, Get, Export, ReKey, DeriveKey, Activate, Revoke, Destroy, Set/Modify/Add/DeleteAttribute, GetAttributes, Locate | **Yes — ownership bypass** |
+
+!!! note "Fail-secure default"
+    When `crypto_officer_users` is configured but a user is not in the list, the server
+    assigns the **Operator** role (minimum privilege). Users are never silently promoted.
+
+!!! info "ISO/IEC 19790 mapping"
+    ISO/IEC 19790:2012 §7.4 defines two mandatory roles: the Crypto Officer (key management
+    and module configuration) and the User (general cryptographic operations). The Cosmian KMS
+    `CryptoOfficer` corresponds to the Crypto Officer and the `Operator` corresponds to
+    the User. The separation between key management and key use is enforced at dispatch.
+
+---
+
+## CryptoOfficer role
+
+The CryptoOfficer role enforces **key lifecycle management**, **key output**, and
+**ownership bypass** as defined by the Crypto Officer role in
+[ISO/IEC 19790:2012 §7.4](https://csrc.nist.gov/pubs/fips/140-3/final).
+
+CryptoOfficers may:
+
+- Create, import, certify, activate, revoke, and destroy objects
+- Access raw key material (`Get`, `Export`) — "key output" per ISO/IEC 19790 §7.4
+- Manage object attributes
+- **Access any object** regardless of ownership (bypass per-object permission checks)
+- **Locate all objects** (bypasses user filtering in `Locate`)
+
+CryptoOfficers **cannot** use keys cryptographically (no `Encrypt`, `Decrypt`, `Sign`, etc.)
+— enforcing the ISO/IEC 19790 separation between key management and key use.
+
+### Mode 1 — Config-only (no ceremony)
+
+```toml
+[roles]
+crypto_officer_users            = ["key-mgr@example.com"]
+crypto_officer_require_ceremony = false   # default
+```
+
+`key-mgr@example.com` is a CryptoOfficer on first connection. Suitable when physical security
+controls or organisational policy already enforce the required trust level.
+
+### Mode 2 — Split-key ceremony required
+
+```toml
+[roles]
+crypto_officer_users            = ["key-mgr@example.com"]
+crypto_officer_require_ceremony = true
+crypto_officer_threshold        = 2   # n (must equal total_parts)
+crypto_officer_total_parts      = 2   # n
+```
+
+CryptoOfficer privileges are **inactive** at startup. The role becomes active only after the
+ceremony completes with all shares tagged `x-cosmian-crypto-officer-ceremony`.
+
+---
+
+## Ceremony lifecycle
+
+### Phase 1 — Provisioning
+
+!!! important "Bootstrap window"
+    The CO candidate is treated as **Operator** (minimum privilege) while
+    `crypto_officer_require_ceremony = true` is active — they cannot call
+    `Create` or `CreateSplitKey` in that state.
+    Provisioning **must** therefore happen in a bootstrap window: run Phase 1
+    while ceremony mode is **disabled** (`require_ceremony = false` or before the
+    `[roles]` section is added), then enable `require_ceremony = true` and restart
+    the server.
+    On re-ceremony (an existing CO is active), the active CO may provision directly.
+
+The CO candidate creates an AES key, splits it into $n$ shares, and distributes them
+to custodians — all during the bootstrap window.
+
+```mermaid
+sequenceDiagram
+    actor Candidate as CO candidate<br/>(bootstrap window, no ceremony yet)
+    participant KMS
+
+    Note over Candidate,KMS: Phase 1 — Ceremony provisioning (ceremony mode OFF)
+
+    Candidate->>KMS: Create(AES-256) → ceremony_key_id
+    Candidate->>KMS: CreateSplitKey(ceremony_key_id,<br/>threshold=n, parts=n,<br/>method=XOR)
+    KMS-->>Candidate: [share_1_id, share_2_id, ..., share_n_id]
+
+    Note right of KMS: Shares auto-tagged with<br/>x-cosmian-crypto-officer-ceremony
+
+    loop For each custodian i
+        Candidate->>KMS: GrantAccess(share_i_id → custodian_i, Get)
+    end
+
+    Note over Candidate: Enable crypto_officer_require_ceremony=true → restart KMS
+    Note over Candidate: Share IDs distributed out-of-band to custodians
+```
+
+### Phase 2 — Activation ceremony
+
+**One candidate — one ceremony.** A single person in `crypto_officer_users` calls
+`JoinSplitKey`. Only that person becomes an active CryptoOfficer; other users in the
+list remain Operators until they complete their own ceremony.
+
+The candidate assembles all $n$ custodians who each grant access to their share, then
+calls `JoinSplitKey` with all share UIDs. The server:
+
+1. Retrieves each share — the candidate must have `Get` on each.
+2. Verifies all shares carry the `x-cosmian-crypto-officer-ceremony` attribute.
+3. Verifies all shares originate from the same source key.
+4. Verifies the share count equals the threshold.
+5. Verifies the candidate is in `crypto_officer_users`.
+6. Reconstructs the secret via XOR.
+7. Persists a `crypto_officer_activations` record (activated-by user, SHA-256 key
+   fingerprint, participant list, timestamp).
+
+**The activation is bound to the activating user**: only the user named in
+`activated_by` of the sealed record is granted CryptoOfficer status.
+
+```mermaid
+sequenceDiagram
+    actor CO as CryptoOfficer<br/>(candidate)
+    actor Custodian1
+    actor Custodian2
+    participant KMS
+
+    Note over CO,KMS: Phase 2 — Activation ceremony (n=2)
+
+    Custodian1->>KMS: GrantAccess(share_1_id → CO, Get)
+    Custodian2->>KMS: GrantAccess(share_2_id → CO, Get)
+
+    CO->>KMS: JoinSplitKey([share_1_id, share_2_id])
+    Note right of KMS: • Verify x-cosmian-crypto-officer-ceremony attr<br/>• Verify all shares from same source key<br/>• Verify count = n<br/>• Verify user ∈ crypto_officer_users<br/>• XOR reconstruction<br/>• persist crypto_officer_activations row
+    KMS-->>CO: JoinSplitKeyResponse(reconstructed_key_id)
+
+    Note over CO,KMS: CryptoOfficer role is now ACTIVE
+    CO->>KMS: GET /access/crypto_officer/status → {enabled: true, ceremony_activated: true}
+```
+
+### Phase 3 — Active use
+
+While the ceremony is active, the CryptoOfficer can manage all keys in the KMS:
+
+```mermaid
+sequenceDiagram
+    actor CO as CryptoOfficer (active)
+    actor Bob as Bob (object owner)
+    participant KMS
+
+    Note over CO,KMS: Phase 3 — CryptoOfficer in use
+
+    Bob->>KMS: Create(AES-256) → bob_key_id
+    Note right of KMS: object owner = Bob
+
+    CO->>KMS: Get(bob_key_id)
+    Note right of KMS: is_crypto_officer(CO) = true<br/>→ ownership bypass granted<br/>CRYPTO_OFFICER_ACCESS logged
+    KMS-->>CO: SymmetricKey (bob_key_id)
+
+    CO->>KMS: Locate(any_attributes)
+    Note right of KMS: find_all() bypasses user filter<br/>returns ALL objects in KMS
+    KMS-->>CO: [bob_key_id, ...]
+```
+
+### Phase 4 — Revocation
+
+Any active CryptoOfficer can disable the ceremony (self-disable). The role becomes
+dormant until a new `JoinSplitKey` ceremony completes.
+
+```mermaid
+sequenceDiagram
+    actor CO as CryptoOfficer (active)
+    participant KMS
+
+    Note over CO,KMS: Phase 4 — Ceremony revocation
+
+    CO->>KMS: POST /access/crypto_officer/disable
+    Note right of KMS: caller must be active CryptoOfficer<br/>UPDATE crypto_officer_activations<br/>SET revoked_at = NOW()
+    KMS-->>CO: 200 OK
+
+    CO->>KMS: GET /access/crypto_officer/status
+    KMS-->>CO: {enabled: true, ceremony_activated: false}
+
+    Note over CO,KMS: CryptoOfficer role is DORMANT<br/>Must complete JoinSplitKey again to reactivate
+```
+
+---
+
+## Security properties
+
+| Property | Guarantee |
+|---|---|
+| **Information-theoretic secrecy** | $< n$ shares reveal zero bits about the secret |
+| **Single-point-of-failure elimination** | No single custodian can activate the role alone |
+| **Insider threat mitigation** | A user in `crypto_officer_users` cannot escalate without all custodians |
+| **Audit trail** | Every activation records: activator, participant list, SHA-256 key fingerprint, timestamp |
+| **Self-revocability** | Any active CryptoOfficer can immediately revoke the ceremony |
+| **Replay prevention** | Re-activation requires re-running the full `JoinSplitKey` ceremony |
+| **No persistent secret** | The reconstructed key is stored in the KMS; ceremony activation is keyed to its SHA-256 hash |
+| **HSM key exclusion** | Ownership bypass does not apply to HSM-backed keys (governed by HSM admin rules) |
