## 1. Purpose

This Project Manual is the entry point to the demo-epb project. It answers:

- What is being built?
- Which documents exist, in what reading order?
- Who is responsible for what?
- How does the development and release cycle work?

## 2. What is demo-epb?

A complete demo of the **slohmaier Dev Process** using an EPB ECU software. The goal is **not** the productive software, but evidence of ASPICE 4.0 / ISO 26262-compliant development.

Detail: `docs/plans/PID.docx`.

## 3. Reading order for new project members

| Day | Document                              | Why                                    |

## 5. Roles and responsibilities

| Role               | Responsibility                                       | Person (demo)            |
|--------------------|-------------------------------------------------------|--------------------------|
| Project Owner      | Strategic decisions, release approval                | Stefan Lohmaier          |
| Technical Lead     | Architecture, code reviews, technical decisions      | Stefan Lohmaier          |
| Safety Manager     | HARA, Safety Case, ASIL conformance                  | Stefan Lohmaier (demo)   |
| QA Officer         | QA Plan maintenance, audit preparation               | Stefan Lohmaier (demo)   |
| Configuration Mgr  | Baselines, releases, git repo hygiene                | Stefan Lohmaier (demo)   |
| Developer          | Implementation per architecture + tests              | Stefan Lohmaier (demo)   |
| Reviewer           | Code and document reviews                            | External reviewer (TBD)  |

In this demo one person fills all roles; in a real project with ASIL-C/D these are to be separated personnel-wise (developer ≠ reviewer for safety-critical code).

## 6. Development lifecycle

```
Requirement
  │
  ▼
Architecture (Markdown + PlantUML)
  │
  ▼
Implementation (C, with @arch + @reqs)
  │
  ▼
Unit test (CppUTest-like framework, with @reqs)
  │
  ▼
Pull request (branch → main)
  │
  ▼
CI: build + test + coverage + MISRA + traceability check
  │
  ▼
Code review (approval required per ASIL)
  │
  ▼
Merge to main
  │
  ▼ (at release point)
Tag v*.*.*
  │
  ▼
CI release workflow: bundle + Gitea release
```

## 7. Release strategy

- **Pull requests** need at least 1 approval (more for ASIL-C/D, see SWE Plan)
- **Tags** of the form `vMAJOR.MINOR.PATCH` trigger the release workflow
- **Release bundle** contains source + all reports + all Word documents
- **Audit readiness** is maintained continuously (git history + document lifecycle)

## 8. Where to report problems

| Problem type         | Where to document                              |
|----------------------|------------------------------------------------|
| Bug                  | Gitea issue (tag `bug`)                        |
| Requirement change   | Gitea issue (tag `requirement`) + Doorstop update |
| Non-conformity       | `docs/non-conformities-md/NC-XXX.md` → Word    |
| MISRA deviation      | `misra/records-md/MISRA-REC-XXX.md` → Word     |
| Safety problem       | Escalate to Safety Manager + NC                |

## 9. Tools

See `infrastructure/` in the iCloud workspace for setup details. Short list:

- **Gitea** (gitea.slohmaier.com) — source control + CI + releases
- **Doorstop-style** Markdown — requirements + architecture
- **PlantUML** — diagrams (embedded)
- **Cppcheck** + **GCC -Werror** — static analysis + MISRA
- **gcov/lcov** — coverage
- **Doxygen** — API doc
- **pandoc** — Markdown → Word/PDF
- **Python** (stdlib) — traceability + report generators
