-## Key Decisions for Your Domain
-- D-016: Internal monologue system - localization of character voice and personality through text
-- D-021: Official title "The Settled Reach"
-- Q-008: Licensing (open question - affects localization scope and supported languages)
-- **D-028: Tagged line pool dialogue system** — Localization advantages: each line is tagged with context metadata (access tier, relationship level, trust threshold, mood). Translators receive rich context. Lines are pooled, not tree-branched — translation scope is predictable.
-- **D-035: Converged tag taxonomy (6+3)** — 9 tags per line provide rich context for translators. 13 situations, 9 topics, 8 moods. Translation scope predictable from pool size.
-- **D-036: Sova Transit District / Van Maanen's Star** — Van Maanen's Star naming conventions (compact, consonant-heavy). Localization note: proper nouns and slang terms need transliteration guides per target language.
-- **D-121: Voice is culture-driven, job as modifier** — localization implication: culture voice cards are the primary translation unit, not individual NPC profiles. Single tycoon character type in v0.2 (D-117) reduces monologue translation scope vs. prior smuggler/detective dual-pool model (D-032 superseded for v0.2).
