+# Changelog
+
+## 0.4.0 hardening
+
+- Normalize vertex-only bow-ties after QEM by deterministically duplicating
+  disconnected incident fans without moving geometry or changing face-corner
+  attributes; true edge-non-manifolds remain rejected.
+- Make shrinkwrap projection transactional. Failed or gate-breaking projection
+  restores the validated candidate and records the rollback reason.
+- Add adversarial topology, standalone engine, and Blender projection rollback
+  regressions grounded in multi-shell photogrammetry parts.
+
+## 0.4.0 - 2026-07-16
+
+- Added Atlas-Q scan analysis and solver portfolio.
+- Added target-scale native QEM proxies and deterministic candidate ensembles.
+- Added exact conforming PairClosure with UV-seam/material propagation.
+- Added area/spatial/component-stratified symmetric RMS, p95, and maximum source
+  error with preset-specific hard gates.
+- Added vertex-fan manifold, true boundary-cycle, component, duplicate-face,
+  winding, concave/crossed-quad, Jacobian, aspect, and target-count validation.
+- Added exact-source versus exact-proxy topology proof status in output and UI.
+- Moved area, diagonal, aspect, Jacobian, and fidelity gates into world space so
+  non-uniform object scale cannot hide stretched quads or large error.
+- Added a 60-degree local quad-warpage ceiling and per-component Euler checks.
+- Added target-scale preprocessing to direct PairClosure and mode-specific
+  field/pairing weights; unsafe concave triangle pairs now remain unpaired.
+- Added ParityPath sparse quad transitions and deterministic target-aware
+  selection against the conservative global corner closure.
+- Added a topology-gated edge-rotation/QEM unlock for irreducible low-budget
+  scan proxies; every round is transactional and signature preserving.
+- Fixed the old collinear per-triangle pure-quad workaround.
+- Fixed duplicate candidate recomputation in TRIAD-Q.
+- Fixed boundary edges being reported as non-manifold.
+- Fixed orphaned mesh data in Replace mode.
+- Preserved material-slot order and isolated baked target materials.
+- Made baking transactional: all settings and datablocks roll back on failure.
+- Added real isolated install/enable smoke tests for both release zip layouts.
+- Added algorithm and photogrammetry workflow documentation, unit coverage, and
+  release packaging.
+
+## 0.3.0
+
+- Added TRIAD-Q Lite, standalone OBJ I/O, seed-swept pairing, and Blender smoke
+  coverage.
