How the primary modules compose 1. 1 Validate VAULT Checks the request, command or approval before anything proceeds. https://fire-vault.com/control/modules/validate 2. 2 Relay FIRE Opens a temporary, time-bound window for an approved purpose. https://fire-vault.com/control/modules/relay 3. 3 Lock VAULT Holds the asset behind identity, role and policy controls. https://fire-vault.com/control/modules/lock Supporting modules - Transfer VAULT Governs what moves between protected environments. https://fire-vault.com/control/modules/transfer - Archive VAULT Preserves the records, logs and evidence the control produced. https://fire-vault.com/control/modules/archive - Execute FIRE Fires the control action the moment a signal demands it. https://fire-vault.com/control/modules/execute 03 How it reads end to end ## The Blueprint in full. Validate checks the request before any door opens. Relay creates a controlled, time-bound access window. Lock ensures only approved users, roles or conditions can use it. Transfer governs what moves between environments, Archive preserves the activity for audit and Execute can revoke the path on signal. 04 Sector relevance ## Where CP-03 applies.
