📝 docs(adr): homogenize 23 ADRs + rewrite README (Tâche 7 migration) (#18)

Browse Source 
## Summary

Homogenize all 23 ADRs to a single canonical header format, and rewrite `adr/README.md` to match the actual state of the corpus.

This is **Tâche 7** of the ARCODANGE Phase 1 migration (Claude Code → Mistral Vibe). Independent from PR #17 (Tâche 6 — restructure AGENTS.md) — both can merge in any order. No code changes; only documentation.

## Changes

### 1. Homogenize 21 ADR headers (commit `db09d0a`)

The audit (Tâche 6 Phase A, Mistral intent-router agent, 2026-05-02) had identified **3 inconsistent header formats** :

- **F1** — list bullets (`* Status:` / `* Date:` / `* Deciders:`) : 11 ADRs (0001-0008, 0011, 0014, 0023)
- **F2** — bold fields (`**Status:**` / `**Date:**` / `**Authors:**`) : 9 ADRs (0009, 0010, 0012, 0013, 0015, 0016, 0017, 0018, 0019)
- **F3** — dedicated section (`## Status\n**Value** ✅`) : 5 ADRs (0020, 0021, 0022, 0024, 0025)

Plus mixed metadata names (Authors / Deciders / Decision Date / Implementation Date / Implementation Status / Last Updated) and decorative emojis on status values made the corpus hard to scan or template against.

**Canonical format adopted** (see `adr/README.md` for full template) :

```markdown
# NN. Title

**Status:** <Proposed | Accepted | Implemented | Partially Implemented | Approved | Rejected | Deferred | Deprecated | Superseded by ADR-NNNN>
**Date:** YYYY-MM-DD
**Authors:** Name(s)

[optional **Field:** ... lines]

## Context...
```

**Transformations applied** (via `/tmp/homogenize-adrs.py` script, 23 files scanned, 21 modified — 0010 and 0012 were already conform) :

- F1 list bullets → bold fields
- F2 cleanup : `**Deciders:**` → `**Authors:**`, strip status emojis
- F3 sections : `## Status\n**Value** ✅` → `**Status:** Value` (single line)
- Strip decorative emojis from `**Status:**` and `**Implementation Status:**`
- Convert `* Last Updated:` / `* Implementation Status:` / `* Decision Drivers:` / `* Decision Date:` to bold
- Date typo fix : `2024-04-XX` → `2026-04-XX` for ADRs 0018, 0019 (off-by-2-years in original)
- Normalize multiple blank lines after header (max 1)

**ADR body content is preserved unchanged.** Only headers transformed.

### 2. Rewrite `adr/README.md` (commit `d64ab02`)

Previous README had multiple inconsistencies :

- Index table listed wrong titles for ADRs 0010-0021 (looked like an aspirational forecast that never matched reality — e.g. "0011 = Trunk-Based Development" but real 0011 is absent and Trunk-Based Development is actually 0017)
- Listed entries for ADRs 0011 (validation library) and 0014 (gRPC) but **these files do not exist** in the repo
- 0024 (BDD Test Organization) was missing from the detail list
- Template still showed the obsolete F1 format (`* Status:`)
- Decorative emojis on every status entry

Rewrite :

- Index table **regenerated from actual file contents** (title from H1, status from `**Status:**` line) — emoji-free, accurate
- Notes that 0011 / 0014 are not currently in use (reserved)
- Updated template block matches the canonical format
- Status Legend extended with `Approved`, `Partially Implemented`, `Deferred`
- Added note that 0026 is the next free number for new ADRs

## Test plan

- [x] All 23 ADRs follow `**Status:**` / `**Date:**` / `**Authors:**` (verified via grep)
- [x] No more occurrences of `* Status:` (F1) or `## Status` (F3) in any ADR header
- [x] No more emojis on `**Status:**` lines
- [x] `adr/README.md` index links resolve to existing files (no more 0011 / 0014 dead links)
- [x] Pre-commit hooks pass (`go mod tidy`, `go fmt`, `swag fmt`)

## Migration context

Part of Phase 1 of the ARCODANGE migration from Claude Code to Mistral Vibe. Tâche 7 of the curriculum.

Independent from PR #17 (which restructures `AGENTS.md`). The two PRs touch disjoint files — no merge conflict expected when both are merged.

🤖 Generated with [Claude Code](https://claude.com/claude-code) (Opus 4.7, 1M context). Mistral Vibe (intent-router agent / mistral-medium-3.5) did the original audit identifying the 3 formats during Tâche 6 Phase A.

## What is an ADR?
An ADR is a document that captures an important architectural decision made along with its context and consequences.
An ADR is a document capturing one significant architectural decision: the **context** that motivated it, the **decision** itself, and its **consequences**. ADRs are append-only — once published, an ADR is not edited (except for typo / status updates). New decisions that supersede previous ones are recorded as new ADRs that explicitly link back.
## Format
## Canonical Format
Each ADR follows this structure:
All ADRs follow the canonical format below (homogenized 2026-05-03):

## How to Add a New ADR
1. Create a new file with the next available number (e.g., `0010-new-decision.md`)
2. Follow the template format
3. Update this README.md with the new ADR
4. Commit the changes
## Status Legend
* **Proposed**: Decision is being discussed
* **Accepted**: Decision has been made and implemented
* **Deprecated**: Decision is no longer relevant
* **Superseded**: Decision has been replaced by another ADR
| Status | Meaning |
|---|---|
| **Proposed** | Decision is being discussed; no implementation yet. |
| **Accepted** | Decision has been made; implementation may be pending or in progress. |
| **Approved** | Same as Accepted; alternative term used in some legacy ADRs. |
| **Implemented** | Decision is fully implemented and in production. |
| **Partially Implemented** | Decision is partly implemented; remainder is deferred or pending. |
| **Rejected** | Decision considered and explicitly rejected. The ADR documents why. |
| **Deferred** | Decision postponed; revisit later. |
| **Deprecated** | Decision is no longer relevant; system has moved on. |
| **Superseded by ADR-NNNN** | Decision has been replaced by another ADR. Always include the link. |
## How to Add a New ADR
1. Pick the next available number (currently next would be `0026`).
2. Copy an existing ADR (e.g., `0001-go-1.26.1-standard.md`) as a starting template.
3. Edit the title, status, date, authors, and content.
4. Update this `README.md` index with the new ADR.
5. Commit using gitmoji convention (e.g., `📝 docs(adr): add ADR-0026 about ...`).
6. Open a PR for review.
