- Remove stale kVOffset (-0.15) from zone_highlight_layer hover detection;
the offset was removed from rendering but left in the hit-test path,
shifting hover ~15% vertically
- Add null guard for cachedGameHandler_ in ChatPanel::inputTextCallback
to prevent dereference before first render frame
- Zero WindowBorderSize in world map ImGui window to eliminate gap
between window edge and map content
- Replace hardcoded cosmic highlight multipliers with displayH×displayH
square rendering, preserving 1:1 aspect ratio at any resolution
- Skip transport waypoints where serverToCanonical zeroes nonzero input
instead of silently building paths with broken (0,0,0) coordinates
- Use length-squared check (posLenSq > 1.0) for spline endpoint
validation instead of per-component != 0 comparison, so entities
near the world origin are no longer skipped
- Fix off-by-one in ChatPanel::insertChatLink buffer capacity check
Extract CatmullRomSpline (include/math/spline.hpp, src/math/spline.cpp) as a
standalone, immutable, thread-safe spline module with O(log n) binary segment
search and fused position+tangent evaluation — replacing the duplicated O(n)
evalTimedCatmullRom/orientationFromTangent pair in TransportManager.
Consolidate 7 copies of spline packet parsing into shared functions in
game/spline_packet.{hpp,cpp}: parseMonsterMoveSplineBody (WotLK/TBC),
parseMonsterMoveSplineBodyVanilla, parseClassicMoveUpdateSpline,
parseWotlkMoveUpdateSpline, and decodePackedDelta. Named SplineFlag constants
replace magic hex literals throughout.
Extract TransportPathRepository (game/transport_path_repository.{hpp,cpp}) from
TransportManager — owns path data, DBC loading, and path inference. Paths stored
as PathEntry wrapping CatmullRomSpline + metadata (zOnly, fromDBC, worldCoords).
TransportManager reduced from ~1200 to ~500 lines, focused on transport lifecycle
and server sync.
