Public Member Functions
void	clear_temporary_matches ()
	Clears all temporary match data, including dedup stamps.

void	clear_temporary_matches_keep_stamps ()
	Clears temporary match arrays while preserving allocated dedup stamp pages. Full match() can reuse prior stamp pages and advance matchVersion instead of zeroing the whole table again.

void	reset_stamps ()
	Clears dedup stamps and resets the match-version counter.

GAIA_NODISCARD uint32_t	next_match_version ()
	Advances and returns the dedup stamp for the next VM match pass.

Public Attributes
cnt::darr< const Archetype * >	matchesArr
	Ordered list of matched archetypes emitted by the VM for the current run.

ArchetypeMatchStamps	matchStamps
	Paged O(1) dedup table keyed by world-local archetype ids. Pages stay allocated on the scratch frame so repeated matches do not keep reallocating heap memory when archetype ids revisit the same ranges.

cnt::darray< const Archetype * >	matchesArrDynPrev
	Previous result membership used when a dynamic rebuild compares reverse-index changes.

uint32_t	matchVersion = 0
	Monotonic dedup stamp used when the same scratch frame is reused by later full match() calls without clearing stamp pages.
