Module scan 

Package dependency scanning and resolution.

This module provides the Scan struct for discovering package dependencies and building a directed acyclic graph (DAG) for build ordering.

Scan Process

1. Create a scan sandbox
2. Run make pbulk-index on each package to discover dependencies
3. Recursively discover all transitive dependencies
4. Resolve dependency patterns to specific package versions
5. Verify no circular dependencies exist
6. Return buildable and skipped package lists

Skip Reasons

Packages may be skipped for several reasons:

• PKG_SKIP_REASON - Package explicitly marked to skip on this platform
• PKG_FAIL_REASON - Package expected to fail on this platform
• Unresolved dependencies - Required dependency not found
• Circular dependencies - Package has a dependency cycle

Structs

ResolvedPackage

A successfully resolved package that is ready to build.

Scan

Package dependency scanner.

ScanCounts

Counts of packages by outcome category.

ScanSummary

Result of scanning and resolving packages.

SkippedCounts

Counts of skipped packages by SkipReason category.

Enums

ScanResult

Result of scanning/resolving a single package.

SkipReason

Reason why a package was skipped (not built).
