System-component lifecycle-hook registry (Layer L0 — shared).
|
|
|
|
Higher-layer system components (e.g. workflowAutomation) register their
|
|
lifecycle hooks here at boot time via ``app.py`` (Composition Root, L7).
|
|
Interface modules read the registry generically — no upward imports needed.
|
|
|
|
Supported events: ``onBootstrap``, ``onMandateDelete``, ``onMandateProvision``,
|
|
``onInstanceCreate``, ``onUserMandateCreate``, ``onUserMandateDelete``,
|
|
``onUserBudgetAdjust``, ``onStorageChanged``.
|
|
|
|
This is the same inversion pattern used by
|
|
``serviceAgent/externalToolRegistry.py`` for agent tools.
