Module error 

Error type for pack-manifest parsing.

All Stage-A parse failures surface as PackParseError. Variants carry enough context (offending key, value, depth, etc.) to produce actionable messages without the caller needing to re-read the YAML.

Enums

PackParseError

Errors produced by crate::pack::parse and related entry points.

Constants

MAX_REQUIRE_DEPTH

Maximum nesting depth for require / when predicate trees. Exceeding this limit yields PackParseError::RequireDepthExceeded; the cap exists to bound recursive evaluation cost at execute time.
