Phase 0 of the pql migration: the decision markdown had two genuine canonical-ID integrity bugs that pql decisions sync silently LWW-collapses. - D-035 was defined twice: a content.md tag-taxonomy record and a perception.md shadowcasting/LOS record, both dated the same day. The tag-taxonomy record keeps D-035; the shadowcasting record is renumbered to D-238 (freshly claimed) with a Renumbered note preserving the history. Inbound refs repointed in architecture.md (x4), questions-architecture.md, and the README perception index row. - R-011 (single currency for Phase 2) was defined three times: once canonically in rejected.md and twice identically in economics.md. The two economics.md copies are removed; rejected.md absorbs the Proposal/Raised-by lines and gains a dedupe note. The economics.md dissent link now points at rejected.md and the footer count drops the rejected-alternative clause. Verified: tooling/db/decision check-dupes reports 0 duplicates; pql decisions validate returns ok. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Rejected Alternatives
Alternatives considered and rejected, with rationale preserved for future reference.
R-001: Stellaris mod
- Rejected: 2026-02-08
- Reason: Character system too shallow, multi-empire assumption conflicts with the Settled Reach's single-civilization focus, wormhole-as-infrastructure not achievable within Stellaris modding. Team Leader's experience with Star Trek: New Horizons confirmed that even well-suited IPs struggle with character connection in Stellaris.
R-002: CK3 total conversion
- Rejected: 2026-02-08
- Reason: Would require building a space map from scratch within CK3's framework - essentially building a game inside a game. The map system fundamentally doesn't support the complexity needed.
R-003: Other existing games (Distant Worlds 2, GalCiv IV, Sins of a Solar Empire II, Victoria 3)
- Rejected: 2026-02-08
- Reason: Each captures at most 40% of what's needed. Smaller modding communities, less mature tools, and none solve the core CK3+Stellaris hybrid requirement.
R-004: Pure Bevy (Rust) — no Godot
- Rejected: 2026-02-09
- Reason: No visual editor (level design is code-only). UI framework in flux. API breaks significantly between versions. For a solo developer who needs visual tools for hand-crafted buildings (D-014), Godot's editor is a massive productivity advantage. Bevy's ECS is used — just not its renderer.
R-005: Pure Godot (GDScript or C#)
- Rejected: 2026-02-09
- Reason: Scene tree paradigm fights ECS-style simulation. Perception queries (D-017) and information boundaries (D-010) map naturally to ECS component queries, not scene tree traversal. Multi-core scaling for expanded content impossible in GDScript. Kept as kill-switch fallback if Rust architecture exceeds time budget.
R-006: Godot + Rust via GDExtension
- Rejected: 2026-02-09
- Reason: gdext is pre-1.0 with breaking API changes. Godot version upgrades break GDExtension ABI. Thread safety at FFI boundary is CRITICAL risk (
Gd<T>is!Send/!Sync). Couples Rust and Godot learning curves. Subprocess/IPC achieves the same architecture without the FFI risk surface, and maps directly to D-010 client-server. Seedocs/architecture/risk-godot-rust-bridge.mdfor full analysis.
R-007: Godot + C++ via GDExtension
- Rejected: 2026-02-09
- Reason: More mature bindings than gdext, but trades Rust's safety guarantees for C++ memory unsafety. No advantage over subprocess/IPC approach. Developer not experienced in C++.
R-008: Fyrox (pure Rust engine)
- Rejected: 2026-02-09
- Reason: Single maintainer. ~1/50th of Godot's community. Less documentation, fewer tutorials, weaker AI training data for Claude Code. Single-maintainer risk unacceptable for multi-year project.
R-009: Custom framework (Rust + raylib/macroquad)
- Rejected: 2026-02-09
- Reason: Maximum control but you build everything — tilemap rendering, camera, UI, audio, input, asset pipeline. Months before testing a mechanic. The game's hard problems are simulation, not rendering — don't reinvent the rendering wheel.
R-010: protobuf for client-server serialization
- Rejected: 2026-02-09
- Reason: Schema evolution across independent deployments is a problem we don't have (one developer, client and server ship together). Poor GDScript support. Rigid schema fights dynamic HUD composition driven by perception modes (D-017). MessagePack's schema-optional nature fits better.
R-011: Single currency for Phase 2 economics
- Rejected: 2026-04-05
- Proposed by: Burnelli-Sheldon (economist), Sprint 32 Workshop #796 Round 1
- Proposal: Use a single currency for the Phase 2 economics simulation to reduce model complexity; exchange-rate mechanics could be added in a later phase.
- Reason: Three currencies create structural economic bloc tension as an emergent property of initialization, requiring no event generation. The Tractus/Mark divide maps directly to the canonical Assembly vs. Compact political divide. Deferring to a later phase would require retrofitting political geography into a running simulation. Complexity cost low; design value high.
- Raised by: Lead directive overruling the recommendation.
- Cross-reference: D-171 (economics.md)
- Note: Canonical location is
rejected.md. Two duplicate copies ineconomics.mdwere removed 2026-06-06 (id-collision cleanup).
R-012: Overheard NPC conversation system (D-078) — scrapped
- Rejected: 2026-04-10
- Reason: The entire NPC ambient interaction model (overheard conversations, room grammar, zone-type NPC population, behavior engine for physical spaces) is scrapped. These systems were designed speculatively before a walkable environment exists. The NPC interaction model will be designed and built from scratch after Phase 5 (world generation at tile level) is complete. All content authored against these systems (overheard.ron, zone-type conversation pools) is orphaned. Related content pattern note in content.md and D-078 in perception.md are superseded.
- Cross-reference: D-078 (perception.md), content pattern note (content.md #664)
