# Fix: Align `futur accessible` canonical lexicon across `v0/livre.md`

## Problem

Corrective chapters 30/32 request a canonical lexicon for the core text, in particular:

- use `futur accessible`,
- avoid rejected synonyms such as `cône de futur`, `espace des futurs`, `futur possible`.

In `v0/livre.md`, rejected synonyms still appeared in multiple places (definitions/headings and some summary statements), creating internal inconsistency with the canonical lexicon.

## Impacts

- Terminology drift for the same concept, breaking the “one concept, one term” policy.
- Mixed naming across definitions, headings, and later references.

## Cause

Lexicon alignment was applied locally in some chapters but not propagated to the Chapter 13/14 definitions and related summary statements.

## Root cause

No global audit/enforcement step was applied to remove rejected synonyms across the full `v0/livre.md`.

## Fix applied

Applied the correction **only** in `v0/livre.md`:

- Replaced `cône de futur` / `cônes de futur` with `futur accessible` / `futurs accessibles` where applicable in Chapters 13–14.
- Replaced `espace des futurs` / `futur(s) possible(s)` phrasings with `ensemble des futurs accessibles` (or equivalent phrasing consistent with `futur accessible`).
- Updated headings and explanatory lines to keep the wording consistent.
- Updated summary statements to avoid rejected synonyms.

## Affected pages

- `v0/livre.md`

## Deployment / regeneration considerations

- If `v0/livre.md` is regenerated from `v0/chapitre*.md`, this fix can be overwritten. The generating pipeline should be checked if rejected synonyms reappear.

## Analysis / verification steps

- Search in `v0/livre.md` for `cône de futur` / `cônes de futur` and ensure no matches remain.
- Search in `v0/livre.md` for `espace des futurs` and `futur possible` / `futurs possibles` and ensure no matches remain.
- Check that Chapter 13/14 definitions using \(\mathcal{F}(x)\) are named consistently as `futur accessible`.
