# Fix: Sync `v0/livre.md` Introduction/Fermeture with sources (`v0/introduction.md`, `v0/fermeture.md`)

## Problem

Compared to the source files:

- `v0/introduction.md`
- `v0/fermeture.md`

the corresponding “Introduction” and “Fermeture” slices in `v0/livre.md` were missing several passages, creating information loss between sources and the compiled book.

## Impacts

- Missing statements about stratification (layers) as a methodological requirement.
- Missing transition sentence introducing the three validity/refutability criteria.
- Missing the “Introduction” conclusion paragraph.
- Missing the opening summary sentence of the closure and the final sentence about preserving the foundational rule when extending the framework.

## Cause

Manual consolidation of `v0/livre.md` diverged from `v0/introduction.md` / `v0/fermeture.md` and did not include all source paragraphs.

## Root cause

No systematic sync pass was applied for Introduction/Fermeture after earlier edits on `v0/livre.md`.

## Fix applied

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

- Reintroduced the missing stratification paragraph in the Introduction.
- Reintroduced a neutral transition sentence introducing the three criteria.
- Restored the Introduction conclusion section.
- Restored the missing opening and final sentences of the closure (Fermeture), while keeping canonical lexicon (`futur accessible`) consistent with corrective chapters 30/32.

## Affected pages

- `v0/livre.md`

## Deployment / regeneration considerations

- If `v0/livre.md` is regenerated from `v0/introduction.md` and `v0/fermeture.md`, verify that the pipeline preserves these restored passages.

## Analysis / verification steps

- Compare the Introduction slice in `v0/livre.md` against `v0/introduction.md` and ensure no missing paragraphs remain.
- Compare the Fermeture slice in `v0/livre.md` against `v0/fermeture.md` and ensure no missing paragraphs remain.
- Check `v0/livre.md` contains no rejected synonyms (`cône de futur`, `espace des futurs`, `futur possible`) in these sections.
