Canon Registry

The CDD canon hierarchy — eight tiers from MASTER CANON (TIER 0) to STORY HOOK (TIER 7). Low-tier content is never auto-promoted. The four Canonical Mysteries sit at TIER 5 and are permanently unresolved.

Tier Hierarchy

MASTER CANON

TIER 0

CDD_World_Master.md (L0–L17 / SUPP / 正式变更记录). The absolutely unmodifiable foundation of the entire universe.

HISTORICAL EXPANSION CANON

TIER 1

Unified Chronology, Historical / Institutional / Civilization / Social / Modern archives, and Wave 1–4 NEW HISTORICAL CANON.

SCIENTIFIC EXPANSION CANON

TIER 2

Φ量纲 / k,λ,D 系数 / Φ-能量唯象关系 (Wave 1 §III). Formal scientific expansion of the master framework.

RECONSTRUCTED

TIER 3

Reasonable structural reconstruction (RECONSTRUCTED CANON / RECONSTRUCTED SYSTEM). NOT equivalent to established canon.

INFERENCE

TIER 4

Inferred judgement — not established fact.

OPEN / GAP / CONFLICT

TIER 5

Unresolved questions, missing data, or canon conflicts (includes the four Canonical Mysteries).

PROPOSED

TIER 6

Candidate content that may be added later (e.g. PIN-001 玄枢会). NOT established.

STORY HOOK

TIER 7

Pure fiction interface. Does NOT constitute worldbuilding fact. Must never be promoted to canon.

Integrity Rules

Low-tier content must NEVER be auto-promoted to high-tier canon.
RECONSTRUCTED ≠ CANON. INFERENCE ≠ FACT. STORY HOOK ≠ CANON. PROPOSED ≠ ESTABLISHED. OPEN QUESTION ≠ ERROR.
The four Canonical Mysteries are permanently unresolved. The encyclopedia must not auto-generate, infer, or settle them.
