Review — 2026-04-30 — Verdict: APPROVED (third review, post-fixes)

Scope signal: S Specialists: game-designer, systems-designer, qa-lead, creative-director Blocking items: 1 (Edge Cases line 199 stated RoundToInt but code uses FloorToInt — corrected) Recommended revisions: 4 (Fantasy line 20 reworded to remove node-type-coupling implication; tag TotalStack claim softened to "occurrence count"; 9 new ACs added covering null/empty tag arrays, duplicate tower IDs in ReduceTowerEndurance, non-existent tower/component disassemble failures, and full roster add/remove coverage) Summary: Third review found all second-review blocking items resolved. One new blocking item identified: stale RoundToInt reference in Edge Cases (line 199) contradicting FloorToInt in formula section, ACs, and code. Fixed. Recommended revisions also applied. Creative-director synthesis: GDD is well-structured, VFX/audio specs thorough, state tables complete, core design sound. Integer overflow latent bug and missing ACs judged theoretical/non-blocking. R7/Fantasy tension resolved in creative-director's favor — no affinity rules needed. Prior verdict resolved: Yes — RoundToInt documentation error (line 199) addressed; Fantasy line 20 reworded; 9 ACs added; tag claim softened.

Review — 2026-04-30 — Verdict: APPROVED (fourth review — dependency direction + boss fantasy + tag system fixes)

Scope signal: S Specialists: lean review Blocking items: 0 (all prior items resolved) Recommended revisions: 0 Summary: Fourth review verified all remaining warnings resolved: (1) Dependency direction fixed — Node System removed from upstream dependencies, Tag System added as hard upstream; (2) Tag System GDD now exists and defines TotalStack semantics; Tower Assembly §3 updated to reference it; (3) Boss fantasy line 22 revised to reflect kill-speed pressure; (4) C-W2 (loss-gold AC gap in node-system.md) fixed in parallel. GDD is internally consistent, all formulas verified, cross-system dependencies correct. All 7 systems now approved. Prior verdict resolved: Yes — all 4 warnings from cross-GDD review (C-W1, C-W2, G-W1, G-W5) addressed.

Review — 2026-04-30 — Verdict: NEEDS REVISION (second review, post-fixes)

Scope signal: M Specialists: game-designer, systems-designer, qa-lead, creative-director Blocking items: 0 after revision (6 addressed: TryDisassembleTower implemented; Fantasy contradiction resolved by text revision; rarity formula changed to Floor; array length contract documented; stat floor added; Tag stacking redefined as multiplier) Recommended revisions: 7 (all addressed) Summary: Second review found that all 6 prior blocking items were addressed: (1) TryDisassembleTower now implemented; (2) R3/Fantasy contradiction resolved by revising Fantasy text to reflect free disassembly; (3) Rarity formula changed from Round to FloorToInt, eliminating .5 boundary ambiguity; (4) Array length contract documented as data-authoring constraint; (5) Stat floor added (Max(0, ...)); (6) Tag stacking semantics redefined as multiplier. Additionally, 6 missing ACs added, AC1 split into 5 sub-ACs, AC12 quantified, and Open Question 2 clarified as intentional design decision with dead-end state documented. Prior verdict resolved: Partial — items 1, 2, 4, 5, 6 from first review addressed. Item 3 (rarity index formula) was already resolved by code verification.

Review — 2026-04-30 — Verdict: NEEDS REVISION (first review)

Scope signal: M Specialists: game-designer, systems-designer, qa-lead, creative-director Blocking items: 6 | Recommended: 6 Summary: First review of tower-assembly.md found 6 blocking items: (1) TryDisassembleTower referenced in R3 but not implemented; (2) R3/R6 contradiction on 0-endurance component disassembly; (3) Rarity index formula (int)R - 1 needs verification against actual RarityType enum (1-based vs 0-based); (4) Degraded component state has no defined exit path (repair is out-of-scope); (5) Missing AC for assembly attempt with 0-endurance component; (6) Missing AC for disassemble attempt on degraded tower. Creative director synthesis: strong creative vision, excellent VFX/audio specs, core loop solid. Critical issues are implementation gaps and state machine completeness, not fundamental design flaws. Prior verdict resolved: N/A (first review)
