## Objective

Integrate the following editorial evolutions into the manuscript, without changing the underlying mathematical claims:

- expand the formal framing of **selection without optimization** (Chapter 14) by making explicit what is (and is not) assumed when one talks about “optimization”;
- improve navigation across layers and chapters using **dependency maps** at the beginning of each chapter;
- clarify, in Chapter 11, the distinction between **signal** (what circulates) and **structure** (what constrains), and define a minimal criterion for “information support”;
- add a **glossary** for redefined technical terms used in a precise sense.

## Impacts

- Readers can identify, at chapter entry, what prerequisites are used and which layer(s) are activated ([E]/[M]/[P]/[D]).
- Chapter 14 makes the separation explicit between:
  - elimination/filtration under constraints,
  - conditioning / renormalization under a declared probabilistic layer,
  - and decision/optimization when an objective and a choice rule are introduced.
- Chapter 11 states, in-model, when a stable/transmissible structure becomes an information-bearing variable relative to an horizon \(\tau\) (ensemblist or probabilistic).
- A glossary is available as a reference point for terms such as “futur accessible”, “verrouillage”, “compatibilité”, “signal”, “structure”.

## Changes

- **Chapter 14**
  - add a “Critique formelle des modèles d’optimisation” subsection (separating comparability, objective, and choice rule);
  - add a “Persistance par nécessité structurelle” subsection (persistence defined as existence of compatible continuations, not as maximization).

- **Navigation**
  - add a “Carte de dépendances” (Mermaid diagram) at the beginning of chapters 1–16.

- **Chapter 11**
  - add a “Signal, support et structure” section with minimal definitions and an explicit criterion (stability/transmissibility + discriminative power on futures).

- **Glossary**
  - add a `## Glossaire {#glossaire}` section before the annexes;
  - update the table of contents to include a “Glossaire” entry.

## Deployment notes

- No runtime deployment. This is a documentation/manuscript change.
- Ensure Mermaid rendering is available in the target Markdown renderer; otherwise, keep the diagrams as plain text blocks.

## Analysis / verification

- Search for anchors and ensure the table of contents includes `#glossaire` and the corresponding `## Glossaire {#glossaire}` anchor exists.
- Ensure each chapter contains exactly one “Carte de dépendances — Ch. N”.
- Validate that Chapter 14 still uses the declared-layer discipline:
  - ensemblist statements do not assume a probabilistic kernel,
  - probabilistic statements are indexed by a declared \(P\).
