Add the Jackdaw-inspired level-blockout workflow: brush schema, draw/edit modes, CSG, per-face materials.
Turn Blacksite from a single editor crate into a future-game editor platform through static extensions and narrow remote prototypes.
Lock in quality: samples, tests, profiling, docs, and first-run guidance.
Future brush architecture beyond the Jackdaw-inspired MVP: first-class concave authored brushes, compiled brush geometry, robust CSG, material/UV preservation, collision output, and diagnostics.
Close the production loop for an indie game team: animation, audio, navigation, build/package profiles, content validation, release diagnostics, and a documented production-readiness acceptance gate.
