Dewey — Classifier

Assigns taxonomy level (L1-L6) to each document, enforces required documents per project level.

Document Hierarchy (L1–L6)

Level	Type	Examples
L1	Contracts	`contracts/openapi/.yaml`, `contracts/asyncapi/.yaml`
L2	Product Canon	`docs/VISION.md`, `docs/PRD.md`, `docs/ROADMAP.md`, `docs/FEATURES.md`
L3	Engineering Canon	`docs/ARCHITECTURE.md`, `docs/ADR/`, `docs/SAGA/`, `docs/TEST_CASES.md`
L4	Derived	`docs/REFERENCE.md`, `docs/DEV_GUIDE.md`, `docs/STATUS.md`
L5	Artifacts	Generated files (API docs, changelogs, diagrams)
L6	Auxiliary	`README.md`, `CONTRIBUTING.md`, `LICENSE`, templates

What it does

Classifies every document by type and level
Determines project maturity level (L1-L3 based on required docs present)
Validates required documents exist for detected level

Usage

# Via Chronos orchestrator
chronos --path . --preset standard

# Direct invocation
python -m chronos.agents.dewey --path .

Output Format

[warning] missing: Required L2 document missing — docs/ROADMAP.md
[info] classified: docs/ARCHITECTURE.md → L3 Engineering Canon
[info] project_level: L2 (Product Canon) — 3/4 required docs present

Required Documents per Level

Level	Required
L1	At least 1 contract file (OpenAPI/AsyncAPI/JSON Schema)
L2	VISION.md, PRD.md, ROADMAP.md
L3	ARCHITECTURE.md, ADR/ directory
