# Execution platforms
|
|
|
|
Execution platforms isolate hardware-specific capability detection, worker
|
|
selection, patches, kernels, and configuration adjustments.
|
|
|
|
## Candidate invariants
|
|
|
|
### PLATFORM-INV-001: Capabilities are explicit
|
|
|
|
**Rule:** Hardware-dependent behavior MUST be guarded by platform selection or
|
|
capability detection and MUST fail clearly when unsupported.
|
|
|
|
### PLATFORM-INV-002: Portable code remains portable
|
|
|
|
**Rule:** Platform-neutral modules MUST NOT import a vendor implementation
|
|
directly when a common selection interface exists.
|
|
|
|
### PLATFORM-INV-003: Overrides are minimal
|
|
|
|
**Rule:** A platform implementation SHOULD override only behavior that differs
|
|
from the common or upstream implementation.
|
|
|
|
## Safe-change guide
|
|
|
|
Validate common import paths without the target accelerator and run focused
|
|
tests in a fresh `uv` environment on every affected device platform.
