feat(L): all 57 regimes rewritten to canonical IDENTITY template

[LeoLin990405]

What

Full rewrite of every regime's IDENTITY.md to a canonical structure so each civilization's Agent Team authentically mirrors its historical governance.

How

Parallel delegation across 9 AI workers (7 CN backends + Codex + Gemini). Each worker was given:

• The canonical template (docs/IDENTITY-TEMPLATE.md)
• Tang as gold exemplar
• Regime metadata.json + existing IDENTITY.md for reference

Wall time: ~15 min for 56 regimes + 2 retry rounds.

Canonical structure

Every IDENTITY.md now has:

1. 制度简介 (System Overview) — era, duration, significance
2. 组织架构图 (Organization Chart) — ASCII hierarchy, 3–10 organs
3. 角色映射表 (Role Mapping Table) — ≥5 rows with canonical AI roles
4. 决策流程 / 协作流程 (Decision Flow) — step-by-step governance flow
5. 制度特点 (Characteristics) — mechanism-level bullets
6. Pattern 映射 — orchestration pattern from 6 canonical options
7. 历史参考 (Historical Sources) — 3–5 references

Attribution by worker

Worker	Regimes	Notes
cc-mimo	byzantine, persian, ottoman, mongol, russian, soviet, ming, qing, north-south, western-xia, napoleon, us-federal	1M ctx, archive-heavy civs + retries
cc-glm	song, yuan, han, sui, five-dynasties, three-kingdoms	Chinese reasoning
cc-qwen	xia, shang, zhou, qin, jin	Early Chinese dynasties
cc-doubao	taiping, liao, jin-jurchen, roc, viking	General coding
cc-stepfun	sparta, prussia, zulu, meiji, maurya, inca	Discipline/logic civs
cc-minimax	carthage, venice, swiss, aztec, mali, sumeria	Fast inference, smaller polities
codex	roman-republic, roman-empire, british	European structures
gemini	athens, caliphate, egypt, shogunate, habsburg, khmer, safavid, hre, joseon, mughal, polish	Cross-continental + retries

Rejection incidents

• cc-kimi returned {"error":{"type":"invalid_request_error","message":"The request was rejected because it was considered high risk"}} for all 6 assigned regimes (ming/qing/joseon/polish/hre/mughal). Content filter triggered by political governance topics. Reassigned to cc-mimo + gemini.
• codex timed out mid-write on napoleon/us-federal. Reassigned to cc-mimo.

Test plan

• npm run validate:regimes — 0 errors, 40 alias warnings (expected)
• All 57 regimes have required canonical H2 sections
• Role mapping tables have ≥5 rows each
• npm test — 9/9 unit tests pass
• Deferred: historical accuracy review (sample 5-10 regimes with a human historian)
• Deferred: end-to-end tournament run to verify agent counts match new tables

Risks

• AI-authored historical content may have inaccuracies. The provenance is recorded in commit message; future corrections can target specific regimes.
• All 7 CN backends' outputs vary in style/depth. Visual consistency is not guaranteed.
• No single human reviewed all 57 files; quality varies by worker and by regime.
