## 1. What you'll see

PRs authored by "Gabriel Radureau" with commit messages ending in "Mistral Vibe" references. PR titles start with gitmoji. Branch names follow `vibe/<slug>` pattern.

| PR | Date | Title | Branch | Status |
|----|------|-------|--------|--------|
| #67 | 2026-05-05 | :memo: docs: email infrastructure | `vibe/batch4-task-a-email-infra` | Merged |
| #74 | 2026-05-05 | :robot: feat: BDD Mailpit helper | `vibe/batch5-task-b-bdd-mailpit` | Merged |
| #75 | 2026-05-05 | :elephant: feat: magic_link_tokens table | `vibe/batch5-task-c-db-magic-link` | Merged |
| #76 | 2026-05-05 | :rocket: feat: magic link handlers | `vibe/batch5-task-d-handlers` | Merged |

## 2. The pattern (high-level)

```
Operator Brief → Worktree Setup → Worker Execution → PR Lifecycle → Merge
```

### 2.1 Operator brief
Human or trainer (Claude) writes a `CONTEXT.md` brief in a workspace under `~/Work/Vibe/workspaces/<slug>/`. The brief contains:
- Mission statement
- Goal and constraints
- Process instructions
- Hard rules
- Specification

### 2.2 Worktree setup
A `vibe-workspace.sh --worktree` script creates an isolated git worktree:
- Branches from current `origin/main`
- Creates branch `vibe/<slug>`
- Isolates git state in a dedicated directory
- No race conditions (addresses Q-038)

### 2.3 Worker execution
A Mistral Vibe worker (`vibe -p`) runs end-to-end:
1. Reads the brief from `CONTEXT.md`
2. Executes coding tasks (codes, builds, tests)
3. Commits changes with appropriate messages
4. Pushes to remote branch
5. Opens PR via Gitea API
6. Attempts auto-merge

### 2.4 Parallel operation
- Multiple workers run concurrently (2-4 typical)
- Each worker operates in its own worktree
- No git checkout collisions
- Shared origin main as base

### 2.5 Dispatch orchestration
A `dispatch-batch.sh` script:
- Orchestrates batches of 2-4 workers
- Auto-merges PRs that workers opened but didn't merge
- Ensures all PRs reach merged state
- Handles cross-worker dependencies

---

## 3. Why this works

### 3.1 Worktree isolation
Git worktrees provide complete isolation of git state. Each worker has its own:
- Working directory
- Index (staging area)
- HEAD pointer
- Branch reference

This eliminates race conditions documented in Q-038 of the harness logs.

### 3.2 Pre-fetched origin
Origin is pre-fetched before worktree creation (Q-060 fix). This guarantees:
- All workers branch from current main
- No stale base branches
- Consistent starting point across batch

### 3.3 Full PR lifecycle
Workers handle the complete PR lifecycle:
- Code implementation
- Build and test execution
- Commit with proper conventions
- Push to remote
- PR creation via Gitea API
- Merge via Gitea API (squash merge default)

### 3.4 Trainer takeover
For the rare gaps (~5% of cases):
- Price-cap restrictions
- Broken Mistral tests
- Ambiguous requirements

Trainer (Claude) takeover within ~5 minutes covers these edge cases.

## 4. How to read PR provenance

### 4.1 Commit message markers
Look for these patterns in commit messages:

| Marker | Meaning |
|--------|---------|
| `Mostly Mistral Vibe authored` | Mixed human + AI authorship |
| `100% Mistral autonomous` | Fully autonomous workflow |
| `batch<N>-task-<X>` | Brief slug reference |
| `Q-058 trainer takeover` | Specific quirk reference |
| `Q-062 fix applied` | Quirk mitigation applied |

### 4.2 Branch naming
Branch names encode the workflow:
```
vibe/<batch>-<task>-<description>
```
Examples:
- `vibe/batch4-task-a-email-infra`
- `vibe/batch10-task-mistral-pattern-doc`

### 4.3 PR title conventions
PR titles use gitmoji prefix:
- `:memo:` - Documentation
- `:robot:` - AI/automation
- `:elephant:` - Database
- `:rocket:` - Feature
- `:test_tube:` - Testing
