NPC-scoped line ID scheme (D-035) works for hand-authored content but
will produce slug collisions with auto-generated populations (D-029).
Tracked as open question with ticket #544.

Re-scope #501 hub teleport as Gauntlet-only dev tool. Production
travel must be diegetic: local gate → system gate → target menu →
destination, gated by region safety, with asymmetric information
exposure (NPCs observe arrivals/departures).

Add Albert Ford's symmetric shadowcasting algorithm using rational
fraction slopes. Benchmarked 1.2-10.5x faster than recursive with
guaranteed symmetry (if A sees B, B sees A). Resolves Q-018 as D-035.

Six new open questions identified by the Tyre/Troblum architecture
review: shadowcasting algorithm selection, entity ID stability,

Replace monolithic 474-line DECISIONS.md with 7 domain files under
decisions/: architecture, perception, content, scope, process,
questions, rejected. Each file owns its decisions with cross-reference
hyperlinks. Root DECISIONS.md becomes a redirect with domain index.
Reduces per-agent context load by ~70-80% (80-150 lines vs 474).
Taxonomy: architecture (D-008..D-031), perception (D-011..D-019),
content (D-023..D-029), scope (D-001..D-027), process (D-004..D-022),
questions (Q-001..Q-011), rejected (R-001..R-010).
Restores D-002 original text (was a tombstone referencing D-005).
