BIR - BRIK-64

BIR is the intermediate representation below PCD. It is the layer where a circuit description can be normalized for analysis, execution planning and target generation.

Where BIR Fits

PCD source -> parser -> normalized representation -> BIR -> generated artifact

PCD is the authoring surface. BIR is not the language an agent should invent by hand unless a task explicitly asks for low-level representation work.

What BIR Is For

Making generated structure easier to analyze.
Preserving a lower-level representation of the PCD.
Feeding compiler or runtime workflows.
Supporting artifact comparison when hashes and versions are available.

Agent Guidance

Agents should report BIR only when a command produced it or a source file explicitly contains it. Do not infer BIR content from a high-level explanation. When BIR appears in a report, include:

PCD source:
Command:
BIR artifact:
Artifact hash:
Tool version:
Evidence status:

Evidence Status

BIR can support an engineering statement only under a stated inspected scope. A BIR file by itself does not describe the whole project, the runtime environment, or every generated target.
