Status: Accepted

Context
=======

Blacksite is evolving from a game-specific editor scaffold into a reusable
Bevy editor sandbox for future game work. The Jackdaw editor provides useful
public reference material for editor workflows such as brush geometry, material
browser organization, terrain tools, physics placement, project launchers, and
extension boundaries.

The roadmap should use those references as product and workflow inspiration
without accidentally turning Blacksite into a fork, importing code without
attribution, or overriding Blacksite's existing authoring/hydration model.

Decision
========

Treat Jackdaw as an inspiration source, not as an architecture or format
authority. Blacksite keeps its current foundations: Bevy DynamicScene RON,
schema stamping and migration, authoring-only validation, hydration into runtime
components, in-process PIE, and the unified viewport.

Each Jackdaw-inspired ticket must identify whether the work is:

- Design-inspired: adapted from public behavior, screenshots, docs, or workflow
  descriptions.
- API-inspired: adapted from public API shape or concepts without copied code.
- Code-derived: containing copied or closely translated source code.

Code-derived work requires a source URL, upstream commit or release reference,
compatible license confirmation, and preserved file-level notices when required
by the source license. Prefer clean-room implementation for geometry, terrain,
operators, and extension APIs because Blacksite's scene and runtime ownership
model differs from Jackdaw's.

Consequences
============

The Jackdaw roadmap can be used for planning and prioritization while keeping
Blacksite's architecture coherent and auditable.

M0-M5 planning details live in `.cursor/plans/` until implemented. Durable
decisions move into `docs/adr/` or `docs/editor/`; user-visible workflows move
into the root README. The Gitea issue tracker is the production task board, but
docs remain the long-term source for accepted policy and architecture.

Reviewers should reject Jackdaw-inspired changes that do not declare their
inspiration level or that copy source without license and source attribution.
