## Services

| Service | Port | Access | Description |
|---------|------|--------|-------------|
| Gitea | 3000 | localhost (via Caddy) | Git web UI |
| Gitea SSH | 22/222 | Public | Git over SSH |
| PostgreSQL | 5432 | Docker internal | Database |
| SeaweedFS S3 | 8333 | Tailscale only | S3-compatible storage |
| SeaweedFS Filer | 8888 | Docker internal | File interface |
| Prometheus | 9000 | Tailscale only | Metrics |

## Server Access

**Server:** bigbox (100.106.66.7)

```bash
# SSH to bigbox
ssh bigbox

# Navigate to stack directory
cd ~/gitea-stack

# View container status
docker compose ps

# View logs
docker compose logs -f gitea

# Restart Gitea
docker compose restart server

# Stop entire stack
docker compose down

# Start stack
docker compose up -d
```

## 1Password Secrets

Vault: `TerraphimPlatform`

| Item | Purpose |
|------|---------|
| gitea-postgres | PostgreSQL password |
| gitea-s3 | S3 access key and secret key |

### Re-deploying with 1Password

1. Source the 1Password authentication:
   ```bash
   source ~/op_zesticai_non_prod.sh
   ```

2. Inject secrets and deploy:
   ```bash
   cd ~/gitea-stack
   op inject --in-file ../gitea_config/docker-compose.yml.template --out-file docker-compose.yml
   docker compose up -d
   ```

## Storage Configuration

### S3 Buckets

- **gitea** - Attachments, avatars, repository files
- **gitea-lfs** - Git LFS objects

### Gitea Storage Settings

The following storage types are configured to use S3 (Minio):

- `[attachment]` - File attachments
- `[picture]` - Avatars and images
- `[lfs]` - Git LFS objects
- `[storage]` - Default storage configuration

Local storage is used for:
- Git repositories (`/data/git/repositories`)
- Database (PostgreSQL)

## Caddy Configuration

Caddy is already running on bigbox. The git route is appended to `/etc/caddy/Caddyfile`:

```
git.terraphim.cloud {
    reverse_proxy localhost:3000
}
```

To update Caddy config:
```bash
ssh bigbox
sudo vim /etc/caddy/Caddyfile
sudo caddy reload
```

## Monitoring

**Prometheus:** http://100.106.66.7:9000 (Tailscale only)

Scrape targets configured in `prometheus/prometheus.yml`.

## Troubleshooting

### Check Gitea status
```bash
ssh bigbox
docker compose ps
docker logs gitea
```

### Check S3 connectivity
```bash
ssh bigbox
docker exec gitea curl -s http://s3storage:8333/
```

### Reset PostgreSQL password
```bash
ssh bigbox
docker compose exec db psql -U gitea -c "ALTER USER gitea WITH PASSWORD 'newpassword';"
```

### View S3 buckets
```bash
ssh bigbox
curl -s http://localhost:8888/bucket/
```

## Backup

To back up the Gitea data:

```bash
# On bigbox
cd ~/gitea-stack
docker compose stop
tar -czf gitea-backup-$(date +%Y%m%d).tar.gz gitea/ postgres/ seaweedfs/
docker compose start
```

## Updates

To update Gitea to a new version:

1. Edit `docker-compose.yml.template`:
   ```yaml
   image: gitea/gitea:NEW_VERSION
   ```

2. Re-inject secrets and deploy:
   ```bash
   source ~/op_zesticai_non_prod.sh
   op inject --in-file ../gitea_config/docker-compose.yml.template --out-file docker-compose.yml
   docker compose up -d --build
   ```

## GitHub Mirroring

See `MIRRORING-GUIDE.md` for bidirectional GitHub ↔ Gitea mirroring setup.

## AI Agent Skill (Gitea Task Management)

Added 2026-02-18. Provides AI agents with project and task management via Gitea API.

### Architecture

Dual-mode: gitea-mcp (75+ tools for standard CRUD) + curl/jq shell helpers (milestones, workflow labels, dependencies -- areas where gitea-mcp has gaps).

### Key Constraint

Gitea 1.22.6 has NO project board REST API. Milestones serve as project containers with built-in progress tracking.

### Files

| File | Description |
|------|-------------|
| `.agents/skills/gitea/SKILL.md` | Agent skill document with all helpers |
| `.agents/skills/gitea/setup-labels.sh` | Idempotent repo + 12 label creation |
| `.agents/skills/gitea/test-gitea-skill.sh` | 10 integration tests (26 assertions) |
| `.docs/RESEARCH-gitea-agent-skill.md` | Phase 1 research (verified against live) |
| `.docs/DESIGN-gitea-agent-skill.md` | Phase 2 design document |

### Default Task Repository

`terraphim/agent-tasks` -- overridable via `GITEA_OWNER` and `GITEA_REPO` env vars.

### Authentication

```bash
source ~/op_zesticai_non_prod.sh
export GITEA_TOKEN=$(op read "op://TerraphimPlatform/git.terraphim.cloud-admin-token/credential")
```

### Workflow Labels

12 scoped labels across 3 scopes (workflow, priority, type). Workflow state machine: `ready -> in-progress -> blocked -> done`.

### Running Tests

```bash
source ~/op_zesticai_non_prod.sh
export GITEA_TOKEN=$(op read "op://TerraphimPlatform/git.terraphim.cloud-admin-token/credential")
.agents/skills/gitea/test-gitea-skill.sh
```

All 26 assertions pass against live Gitea 1.22.6 as of 2026-02-18.

### Critical API Gotchas

1. **Label exclusivity is UI-only** -- API POST `/labels` just appends. Must use PUT with label swap pattern (get current, filter `workflow:*`, add new, PUT all).
2. **Assignees** -- Use `PATCH /issues/{index}` with `{"assignees": [...]}`. The `POST /issues/{index}/assignees` endpoint does not exist in 1.22.6.
3. **Issue dependencies** -- Body uses `IssueMeta` format: `{"owner": "...", "repo": "...", "index": N}` (NOT `{"depends_on_id": N}`).

## Pre-commit Hooks

Added `.pre-commit-config.yaml` with:
- Trailing whitespace, end-of-file fixer, YAML/JSON check
- Merge conflict and private key detection
- Secret detection via `detect-secrets` (baseline at `.secrets.baseline`)

## Key Files

| File | Description |
|------|-------------|
| `docker-compose.yml.template` | Template with 1Password references |
| `Caddyfile` | Caddy reverse proxy config |
| `deploy-to-bigbox.sh` | Deployment script |
| `s3_config.json.template` | SeaweedFS S3 config template |
| `prometheus/prometheus.yml` | Prometheus scrape config |
| `.github/workflows/*.yml` | GitHub Actions for mirroring |
| `.agents/skills/gitea/SKILL.md` | AI agent Gitea skill |
| `.agents/skills/gitea/setup-labels.sh` | Label setup script |
| `.agents/skills/gitea/test-gitea-skill.sh` | Integration tests |
| `.pre-commit-config.yaml` | Pre-commit hook config |
| `ARTICLE-agent-task-management.md` | CTO voice article (~2800 words) |
| `ARTICLE-agent-task-consolidation.md` | Technical reference article (~6000 words) |
| `lessons-learned.md` | Session discoveries and pitfalls |

## Articles

Two comparison articles documenting the migration from beads/br/agent-mail to Gitea:

| File | Style | Words |
|------|-------|-------|
| `ARTICLE-agent-task-management.md` | CTO voice (bold, narrative) | ~2800 |
| `ARTICLE-agent-task-consolidation.md` | Technical reference (comprehensive) | ~6000 |

Both cover: 1Password integration, Gitea + SeaweedFS infrastructure, all three API gotchas with fix patterns, and honest tradeoff analysis. All commands verified working against live instance.

## Gitea Mirror

The `gitea-infrastructure` repo is now published on both remotes:

| Remote | URL |
|--------|-----|
| GitHub (origin) | https://github.com/terraphim/gitea-infrastructure |
| Gitea | https://git.terraphim.cloud/terraphim/gitea-infrastructure |

**Note:** The `sync-to-gitea.yml` GitHub Actions workflow is failing due to a billing/spending limit issue. Direct push via `op` token was used as workaround. Check GitHub **Settings > Billing & plans** to restore automated sync.

## Session Log (2026-02-18)

### Session 1: Gitea Agent Skill Implementation
- Rewrote Gitea agent skill with verified API patterns (milestones, workflow labels, dependencies)
- Created setup-labels.sh for idempotent repo + label creation
- Created test-gitea-skill.sh with 10 tests (26 assertions), all passing
- Found and fixed 3 API behavior bugs (label exclusivity, assignee endpoint, dependency format)
- Added pre-commit hooks and fixed trailing whitespace across 15 files
- Conducted disciplined research and design phases with live API verification

### Session 2: Articles and Publishing
- Wrote two comparison articles (CTO voice + technical reference) comparing beads/br/agent-mail with Gitea replacement
- All code snippets, commands, and configurations verified against live Gitea instance
- Pushed all commits to GitHub origin/main
- Created `gitea-infrastructure` repo on Gitea and pushed full history
- Discovered GitHub Actions billing issue blocking automated sync-to-gitea workflow

### All Commits (pushed)
- `62e2275` docs: Add articles comparing beads/br/agent-mail with Gitea replacement
- `4ff1821` docs: Update handover and add lessons learned
- `b67284e` chore: Fix trailing whitespace across project files
