Access control (BorgAuth)

All access control in the protocol runs through BorgAuth — a single ACL contract per cyberCORP. BorgAuth uses numeric role levels in a hierarchy, not named roles.

• Source: src/libs/auth.sol

The role model

A role is a uint256. Higher numbers outrank lower ones. onlyRole(role) passes when userRoles[user] >= role — it is a threshold check, not an exact match.

Built-in role constants

Constant	Value
OWNER_ROLE	99
ADMIN_ROLE	98
PRIVILEGED_ROLE	97

Roles the protocol assigns

The CyberCorpFactory and CyberCorp set these levels when a cyberCORP is deployed:

Holder	Level	Why
Company officer (CompanyOfficer.eoa)	200	Set by CyberCorp.addOfficer / by the factory. 200 ≥ 99, so officers also satisfy onlyOwner.
CyberCorp contract	200	So the corp can act on its own auth.
IssuanceManager, DealManager, RoundManager	99 (OWNER_ROLE)	So the manager contracts can call owner-gated functions on the suite.

There are no named roles such as ISSUER_AUTHORITY or OFFICER_AUTHORITY. Authority is the numeric level a contract requires at a given function. Officer = 200 is the level a human officer holds.

BorgAuth functions

uint256 public constant OWNER_ROLE = 99;
uint256 public constant ADMIN_ROLE = 98;
uint256 public constant PRIVILEGED_ROLE = 97;

mapping(address => uint256) public userRoles;
mapping(uint256 => address) public roleAdapters;

function updateRole(address user, uint256 role) external;       // caller must hold OWNER_ROLE
function initTransferOwnership(address newOwner) external;      // caller must hold OWNER_ROLE
function acceptOwnership() external;                            // caller must be pendingOwner
function zeroOwner() external;                                  // caller renounces to role 0
function setRoleAdapter(uint256 role, address adapter) external;// caller must hold OWNER_ROLE
function onlyRole(uint256 role, address user) public view;      // reverts if under-authorised
function matchRole(uint256 role, address user) public view;     // reverts unless exactly equal

• updateRole — the single grant/revoke entry point. Set a user's level up or down. Requires OWNER_ROLE.
• zeroOwner — the owner renounces itself to level 0, permanently removing admin control from contracts using this auth.
• Role adapters — setRoleAdapter plugs in an IAuthAdapter so a role can be satisfied by custom logic (e.g. a credential check) instead of, or in addition to, a stored level.
• Ownership transfer is two-step: initTransferOwnership then acceptOwnership.

Using BorgAuth in a contract: BorgAuthACL

Protocol contracts inherit BorgAuthACL, which holds the AUTH reference and provides modifiers:

Modifier	Passes when the caller's level is…
onlyOwner	≥ OWNER_ROLE (99)
onlyAdmin	≥ ADMIN_ROLE (98)
onlyPriv	≥ PRIVILEGED_ROLE (97)
onlyRole(n)	≥ n
matchRole(n)	exactly n

Example: CyberCorp.addEscrowedOfficerSignature is onlyRole(200) — only an officer (level 200) can call it; most other CyberCorp functions are onlyOwner (level ≥ 99).

A note on onlyIssuanceManager

CyberScrip, CyberCertPrinter, and CyberShares gate their mutating functions with onlyIssuanceManager — a check that msg.sender is the IssuanceManager contract, not a BorgAuth role check. End users act through the IssuanceManager, which itself is authorised via BorgAuth.
