Install Controls
This page covers intent enforcement settings that apply when inventory is installed into an assembly
Install Intent Match
Setting key: require_install_intent_match
What it does
Install Intent Match enforces that inventory meets the intent requirement of the parent assembly when it is installed to the aBOM. If the installed inventory's intent does not meet the parent's intent, the installation is blocked with an error.
When it runs
On aBOM install - when inventory is installed into an assembly via the as-built BOM.
Configuration options
enabled
true / false
Turns the check on or off. Default: false
mode
hierarchical, exact
How the intent comparison is evaluated.
Mode values
hierarchical
The inventory's intent must be equal or higher rank than the assembly's intent. Lower-grade inventory is blocked from installation into higher-grade assemblies.
exact
The inventory's intent must exactly match the assembly's intent. Only exact-match intent is accepted.
Example scenario
A technician attempts to install a Development-grade sensor into a Flight-grade assembly during a run. With require_install_intent_match enabled and mode: hierarchical, the installation is blocked and the technician sees an error. They must either source a Flight-grade sensor or reclassify the inventory before proceeding.
Downgrade on Install
Setting key: downgrade_on_install
What it does
Downgrade on Install automatically lowers the intent of inventory to match the parent assembly's intent when the inventory is installed. For Made on Assembly (MOA) installs, the child's intent is synced to the parent assembly's intent.
This setting reflects the principle that an installed component takes on the quality level of what it becomes part of. A Flight-grade component installed into a Development assembly effectively becomes a Development component, because the resulting assembly is Development.
When it runs
At the moment of aBOM installation - when inventory is installed into an assembly.
The downgrade happens only when the assembly's intent is lower than the inventory's current intent. If the assembly's intent is equal or higher, no change is made. It is recommended to enabled this setting in combination with Install Intent Match above.
Configuration options
enabled
boolean
true / false
Turns the automatic downgrade on or off. Default: false
Example scenario
A Flight-grade actuator is in stock. A technician installs it into a Development assembly. With downgrade_on_install enabled, the actuator's intent is automatically changed to Development at the moment of installation — because it is now part of a Development assembly and can no longer be treated as Flight-grade inventory.
If the technician instead installed the same actuator into a Flight-grade assembly, no downgrade would occur.
