Classes
struct	wowlib::fs::detail::ChainEntry
	One base-tier row. More...
struct	wowlib::fs::detail::MpqChainSpec
	A client version's archive chain: the fixed base tier plus how its patch tier is found. More...
struct	wowlib::fs::detail::ChainMember
	One resolved member of a chain, in load order. More...

Namespaces
namespace	wowlib
namespace	wowlib::fs
namespace	wowlib::fs::detail

Enumerations
enum class	wowlib::fs::detail::ChainEntryKind { wowlib::fs::detail::Fixed , wowlib::fs::detail::LocaleFixed }
	How one base-tier row produces its archive path. More...
enum class	wowlib::fs::detail::PatchScheme { wowlib::fs::detail::None , wowlib::fs::detail::ClassicWildcard , wowlib::fs::detail::UpdateChain }
	How a version's patch tier is discovered on disk. More...

Functions
const MpqChainSpec *	wowlib::fs::detail::findChainSpec (const ClientVersion &version)
	The chain spec for version: exact build match first, then major.minor.patch.
Result< std::vector< ChainMember > >	wowlib::fs::detail::expandChain (const MpqChainSpec &spec, const std::filesystem::path &dataDir, Locale locale)
	Expand a chain spec against a Data directory into concrete members in load order (lowest -> highest priority): the base tier in table order, then the patch tier as ONE list sorted by the client's case-insensitive, extension-stripped filename order (so patch < patch-2 < ..., with base and locale patches interleaved — a high base letter-patch like patch-Z outranks the locale patches).

Detailed Description

Per-version MPQ archive chain tables and their expansion against a real or fake Data/ directory.

Implementation detail of MpqStorage — pure (no StormLib types), so ordering rules are unit-testable without a client.
