# Prysai LLM Playbook: Table of Contents v0.2

Readers who want the platform-neutral method first can open the
[Universal LLM first-task route](routes/universal-core-foundations-EN.md).
It begins with one fictional, text-only rewrite before mapping four extracted
units. It remains `candidate / not_run`; the route does not establish
cross-platform behavior, learner outcomes, or completion time.

> English source-locale directory page. The legacy unsuffixed draft was
> removed during release cleanup; `book/table-of-contents-EN.md` is the
> canonical English table of contents. It keeps all 22 chapters,
> 18 experiments, maturity boundaries, and real-user problem research
> entrances visible without claiming that the chapter or lab corpus is already
> translated or runtime-verified.

## Migration state and link policy

- Page `content_status`: `candidate`; source revision: `dd08a68`.
- The directory contains 22 chapter records and 18 real experiment files.
- Chapters are `candidate`. Labs are `draft` with `run_status: not_run`.
- Chapter 6 has `claim_status: disputed`; Chapter 22 has
  `claim_status: current | disputed`.
- English chapter sources are now available for chapters 1–22 and are the
  canonical English reader route. Labs remain a separate migration track: each
  lab keeps its own `draft` and `not_run` state, and a pending label means the
  English lab file has not yet been reviewed into the locale matrix.
  Shared governance, evaluation, and research documents are marked
  `locale-neutral`.
- No link on this page silently falls back to another locale. A migration
  notice is part of every link whose localized target does not yet exist.

## Experiment index and status boundaries

The repository has 18 real experiment files. Each remains `draft` and
`run_status: not_run`; a directory link is an entry point, not evidence that
the experiment or its learning outcome is verified.
