+# Changelog
+
+## 0.3.6
+
+### Features
+- **10 quality & automation enhancements**
+  - Sensitive word detection (dim 27): built-in political/sexual/violence word lists
+  - Multi-model routing: `modelOverrides` config maps agent roles to different models
+  - Spot-fix revise mode: targeted minimal changes with half token budget
+  - Character dialogue fingerprinting: extracts per-character speaking style from recent chapters
+  - Entity-based context retrieval: lightweight relevant-summary matching from chapter summaries
+  - Post-write constraint validation: regex-based prohibition checks (zero LLM cost)
+  - Temperature retry threading: scheduler→runner→writer for quality gate retries
+  - Failure clustering: per-dimension failure tracking with diagnostic webhook alerts
+  - Auto-detection loop in daemon: audit pass → detect → anti-detect rewrite
+  - Analytics CLI: `inkos analytics [book-id]` for chapter/word/audit statistics
+- Word count control via `--words` flag
+
+### Fixes
+- Align capability declarations with actual implementation (genre enum, audit dimensions, truth file count, revise modes)
+
+## 0.3.5
+
+### Features
+- **12-feature enhancement** (Phases 1–12 from plan)
+  - Chapter summaries for cross-chapter coherence
+  - Structural AI-tells detection (paragraph uniformity, cliche density, formulaic transitions)
+  - Webhook notifications with HMAC signing
+  - Subplot progress board
+  - Emotional arc tracking
+  - Character interaction matrix with information boundaries
+  - Pacing health scoring
+  - AIGC detection API integration (`inkos detect`)

+
+### Fixes
+- Shared prepack/postpack scripts prevent `workspace:*` leaking into npm tarballs

+- CLI UX improvements: auto-detect book-id, `--json` output everywhere, `inkos update` command
+- Variadic args for `review approve/reject`
+
+## 0.3.2

+- API key security: key stored in `.env` only, not in `inkos.json`
+- Optional LLM params (temperature, maxTokens)
+- Global LLM config via `~/.inkos/.env`
+- `inkos init` works without arguments (uses current directory)
+- Friendly LLM error messages + `inkos doctor` API connectivity test
+
+## 0.3.0
+
+### Features
+- Three-layer rule architecture: platform → genre → book
+- Genre profiles: xuanhuan, xianxia, urban, horror
+- Genre-aware architect, 19-dimension auditor, reviser modes (polish/rewrite/rework)

+# Contributing to InkOS
+
+## Setup
+
+```bash
+git clone https://github.com/Narcooo/inkos.git
+cd inkos
+pnpm install
+pnpm build
+```
+
+## Development
+
+```bash
+pnpm dev          # Watch mode (core + cli)
+pnpm typecheck    # Type checking
+pnpm test         # Run all tests
+```
+
+### Project Structure
+
+```
+packages/
+  core/     # Agents, pipeline, state, models — the engine
+  cli/      # Commander.js CLI — thin wrapper over core
+  studio/   # Web UI (future)
+```
+
+### Key conventions
+
+- **TypeScript strict mode** — no `any` unless unavoidable
+- **Immutable patterns** — create new objects, never mutate
+- **Small files** — 200–400 lines typical, 800 max
+- **Zod schemas** — all external data validated at boundaries
+- **Tests** — `vitest`, co-located in `__tests__/`
+
+## Submitting changes
+
+1. Fork and create a feature branch
+2. Write tests for new functionality
+3. Ensure `pnpm typecheck && pnpm test` passes
+4. Open a PR with a clear description
