Flea Flicker 152c52f47c docs(skills): loosen uat→main merge gate; CTO Approve only for novel auth, infra/prod, and risk-flagged
The 2026-06-11 merge-whitelist fix (GRO-2348) added a required_approvals
gate on uat→main merges. That gate is only satisfied by a Gitea Approve
click — the issue-thread QA/UAT-deploy/UAT-regression/security
approvals do not clear it. As a result the CTO is the human-in-the-loop
on every routine release-train PR (GRO-2358, GRO-2359 both hit it).

This change introduces an explicit "uat→main merge-gate policy" in
coding-standards: once the four pre-gates (QA, UAT deploy, UAT
regression, security) are green, the engineer self-merges. A CTO
Gitea Approve click is required only for three categories:

  1. Novel auth / session paths (login, OIDC, OOBE, session
     middleware, token issuance, MFA, new auth provider integrations).
  2. Infra / prod-affecting merges (deploys, manifests, secrets,
     GitOps overlays, CI/CD, main branch protection, prod-affecting
     routing/ingress). All Phase 5 infra overlay PRs in
     groombook/infra still require CTO Gitea Approve without
     exception.
  3. Risk-flagged merges (risk:cto-approve label, or explicit
     CTO/CEO sign-off request in the PR or issue thread).

Phase 4 in sdlc is updated to reflect the new flow: engineer
classifies the PR; CTO Approve happens only for the three categories
above; otherwise the engineer merges once the four pre-gates are
green. The pre-gates themselves do not change.

Software development lifecycle for GroomBook application repos. Covers
Gitea authentication, the 3-branch dev/uat/main strategy, the SDLC
pipeline phases 1-5, the Stage 1 CI image build, the authentication
framework, and application-tool policy. For infrastructure
(groombook/infra), see the devops skill.

# Software Development Lifecycle
This skill governs **application code repos**. For infrastructure (`groombook/infra`), see the `devops` skill. For PR/test discipline and the `cc @cpfarhood` visibility rule, see `coding-standards`. For non-negotiable safety rules, see `safety`.
## Gitea authentication
**Use the `GITEA_TOKEN`** environment variable for all Gitea operations. It is already set in the agent environment. Use the **`tea`** CLI for all Gitea/Git operations (e.g., `tea issue list`, `tea pr create`). The token expires when the environment variable is rotated — re-invoke any Gitea operation if you get a 401.
Gitea is the **primary source of truth**. Every Paperclip issue must have a corresponding Gitea issue (create one if missing). Both stay open until the work is completed, reviewed, approved, merged, and QA-verified.
## Branch strategy
Three long-lived branches map to the three deployment environments:
| Branch | Environment | Who merges | Prerequisites for merge |
|--------|-------------|-----------|-----------|
| `dev` | Dev | Engineer | CI passes |
| `uat` | UAT | Engineer | QA code review approval |
| `main` | Production | Engineer | UAT validation, security review, and the `coding-standards` uat→main merge-gate policy |
**Engineers always target `dev` first** — never `uat` or `main` directly.
- Feature branches: `<agent-name>/<short-description>`.
## Pull requests
All changes happen via pull request. Gitea branch protection requires CI checks to pass. See `coding-standards` for the no-self-merge contract and the `cc @cpfarhood` visibility rule.
```bash
tea pr create --base dev --title "..." --body "... cc @cpfarhood"
```
## SDLC pipeline
### Phase 1 — Dev
1. **Engineer** branches from `dev`, writes code.
2. **Engineer** opens a PR against `dev`.
3. **CI** fail → back to **Engineer**.
4. **CI** pass → **Engineer** merges PR.
5. **CI** builds and deploys automatically to Dev (`https://dev.groombook.dev`).
### Phase 2 — UAT promotion
1. **Engineer** opens a PR from `dev` to `uat`.
2. **CI** fail → back to **Engineer** (return to Phase 1).
3. **CI** pass → **QA** performs code review.
4. **QA** rejected → back to **Engineer** (return to Phase 1).
5. **QA** approved → **Engineer** merges PR.
6. **CI** builds and deploys automatically to UAT (`https://uat.groombook.dev`).
### Phase 3 — User Testing & Security Review
1. **UAT (Shedward Scissorhands)** runs full regression against UAT — every feature, old and new, no exceptions.
2. **UAT** fail → back to **Engineer** (return to Phase 1).
3. **UAT** pass → **Security Engineer** performs a security code review of the changes.
4. **Security** fail → back to **Engineer** (return to Phase 1).
5. **Security** pass → Begin Phase 4.
### Phase 4 — Production Promotion
1. **Engineer** opens a PR from `uat` to `main`.
2. **CI** fail → back to **Engineer** (return to Phase 1).
3. **CI** pass → **Engineer** classifies the PR against the `coding-standards` **uat→main merge-gate policy**:
* **In a category that requires CTO Gitea Approve** (novel auth / session paths, infra / prod-affecting merges, `risk:cto-approve` label or explicit CTO/CEO sign-off request) → Engineer pings the CTO for a Gitea Approve click.
* **CTO** rejected → back to **Engineer** (return to Phase 1).
* **CTO** approved → continue to step 4.
* **Outside all three categories** → no CTO click needed; jump to step 4 once the four pre-gates (QA, UAT deploy, UAT regression, security) are green.
4. **Engineer** merges the PR.
5. **CI** fail → back to **Engineer** (return to Phase 1).
6. **CI** pass → Begin Phase 5.
### Phase 5 — Production Deployment
The **Engineer** opens a PR against `groombook/infra` to update the relevant Kustomize overlay with the new image tag. From this point the work follows the **`devops` skill pipeline** end-to-end — review, merge, and Flux reconciliation are all owned there. On merge, Flux rolls out the updated pods to production (`https://demo.groombook.dev`).
## Stage 1 CI — Image build
Triggered automatically on every merge to `main` in an application repo:
- Builds and tags the Docker image: CalVer (`YYYY.MM.DD[.N]`), `latest`, and `sha-<hash>`
- Pushes tagged images to `git.farh.net/groombook/<service>` (see `coding-standards` for the registry and CalVer policy)
- Creates a CalVer git tag in the source repo
Stage 2 (Flux GitOps deployment) is owned by `devops`.
## Authentication
* **Framework:** Better-Auth.
* **OAuth Providers:** GroomBook (Authentik), Google, and Apple.
* **SSO:** Authentik OIDC at `https://auth.farh.net` (credentials in `authentik-credentials` secret).
* **Never build custom authentication.**
## Application tools (canonical, not alternatives)
These are application-level dependency choices. Alternatives are policy violations:
* **Database:** CloudNativePG-managed Postgres — no SQLite, MariaDB, or MySQL.
* **Cache / pub-sub:** DragonflyDB — no Redis.
* **Authentication:** Better-Auth + Google + Apple + Authentik (see Authentication above).
* **Dependency updates:** Mend Renovate. **Dependabot is not used and will not be used.** Do not configure it.
* **Browser automation:** the `playwright` MCP server (`http://playwright:8931/mcp`). Target dev only — never test production.
