Annotation

• Immediate include surface: `stdlib.h`, `stddef.h`, `stdio.h`, `unistd.h`, `errno.h`.
• Detected declarations: `function Copyright`, `function policy_to_buffer`, `function write_boot_policy`, `function main`.
• Atlas domain: Support Tooling And Documentation / scripts.
• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
