- remove render.mjs/render.test.mjs (scope-lock now writes REQ cards directly)
- add yaml-config.mjs: minimal 2-level YAML reader (+ tests)
- apply-ddl: parse config-vars.yaml database: section instead of .env.local dotenv; drop assertSafeDbTarget host-whitelist + schema guards (config-vars.yaml is trusted)
- merge-gitignore/validate-ddl: self-contained pathToFileURL comment (no longer 'see render.mjs')

Independent Claude + Codex review of the working-tree diff surfaced
23 issues; all applied in-place across three domains.

workflows/coding.mjs (9):
- spec/plan/verify/review prompts now git-commit their artifacts
  (closes milestone-dirty-worktree halt risk)
- CHECKBOX_STATE_SCHEMA requires `state` + defensive guard in reviewWithFixLoop
- writeDocs08FieldPromptM scopes edits to module via line anchor
- assertSafeId guards Router output (module/REQ/FE ids)
- featureLoop captures reviewWithFixLoop's return value
- dateFromArtifactPath rejects impossible dates (9999-99-99 etc.)
- terminal HALT review-unresolved message disambiguated
- updated comment on top-level `return` (ESM vs node --check)

lib/validate-ddl.mjs + tests (10):
- extractType preserves unsigned/signed modifiers
- KEY/INDEX fallthrough no longer creates spurious 'KEY' columns
- FOREIGN KEY REFERENCES accepts schema-qualified `db.table`
- index keys normalized to name:kind:cols (UNIQUE-aware)
- FK keys include ON DELETE action (defaults to RESTRICT)
- CREATE TEMPORARY TABLE parsed
- parseForeignKeyBullet/parseIndexBullet reject prose bullets
- +10 regression tests (62 total, all pass)
- merge-gitignore.mjs docstring synced to implementation

skills/ (4):
- docs-06 template header: § 一~二 → § 一~三
- downstream-gen §A steps renumbered 1-7 (was 1,3,4,5,6,7,8)
- docs-08 initial template adds tokens.css checkbox
- coding-start drops "已在后台启动" wording (Workflow is synchronous)

- 新增 scope-lock/templates/config-vars-template.yaml：非敏感项目级配置
  （包名/端口/前端包名/初始账号）+ secrets_ref 键名引用 .env.local；
  A1 E.2 锁定。docs/07 改为只记规则/约定不记具体值。
- 连带更新 skeleton-gen / plan-start 闸门 2 / frontend-scope-lock /
  CLAUDE-template / README / docs-06·07 模板对齐新的配置分层与 docs/06 小节编号。
- lib 修复（含回归测试）：
  - apply-ddl: 抽出 resolveDbConfig，DB_SCHEMA 为契约 schema 键，缺库名 fail-closed (M1)
  - render: 用 Object.hasOwn 拒绝原型链继承键，guard process.argv[1]
  - validate-ddl: 解析 ### 索引/### 外键 bullet (C2)、剥 SQL 注释防幽灵表 (L4)、PRIMARY 归一化
- coding.mjs: Router 把全部前端 FE 聚合为单一末尾 frontend-phase 模块；
  新增 branchSetupPrompt 功能分支生命周期 (C1)；diff 区间改三点 diff；fix 后复跑 verify。
