Operating practice
Each practice is a question you can ask of any system. The systems listed under one are the systems that answer it concretely, drawn from their own records.
L3D-PRA-001
Observe
What is actually true now, and what evidence supports that conclusion?
Establish actual state through bounded measurement, inspection, or read-only collection, rather than assuming a command or a declared configuration reflects reality.
Demonstrated by Project Feldspar, MachineIQ, RepoLens, HA Light Controller, Control Center, Hardware Radar, ai-spy
L3D-PRA-002
Model
What are the authoritative objects and states, and where are the boundaries?
Represent entities, state, boundaries, dependencies, time, and failure modes explicitly enough to reason about them.
Demonstrated by MachineIQ, RepoLens, Project Standards, Control Center, Hardware Radar, Agent Pseudocode, Star Trek: Alter Course
L3D-PRA-003
Control
Who is allowed to act, through which interface, and on which transition?
Make authority, interfaces, state transitions, and consequential operations explicit and bounded.
Demonstrated by Project Feldspar, Project Standards, docmend, Control Center, Agent Pseudocode, DFBU, Star Trek: Alter Course
L3D-PRA-004
Protect
What is assumed unreliable, and what consequence must stay outside that boundary?
Limit exposure and consequence through least privilege, isolation, safe defaults, bounded input, fail-closed behaviour, and explicit refusal.

L3D-PRA-005
Verify
What counts as success, and how is it proven instead of assumed?
Check that an intended result, invariant, deployment, or state transition is complete and correct, rather than assumed.

L3D-PRA-006
Recover
What state must survive, and can a partial operation be resumed safely?
Preserve a credible path to resume, restore, roll back, or reconstruct after interruption or failure.
