Developer User Stories

This document contains user stories for the Developer stakeholder role — engineers extending, maintaining, or contributing to the firmware and documentation.

User Story: Modular Firmware Extensibility US_DEV_1

status: implemented tags: developer, firmware, extensibility links outgoing: REQ_SYS_ARCH_1 links incoming: SPEC_DEV_OV_INDEX_WHO

Role: Developer Story: As a developer, I want a modular component structure so that I can add a new sensor or display type without modifying the core application logic. Value: The component-based architecture allows extending the firmware by adding or replacing components. Existing components serve as reference implementations. The developer is not required to understand the full system to add a new peripheral.

User Story: Traceable Supporting Documentation US_DEV_2

status: implemented tags: developer, documentation, traceability links outgoing: REQ_DEV_DOC_1 links incoming: REQ_DEV_DOC_1, REQ_DEV_README_1, REQ_DEV_OV_INDEX_1, REQ_DEV_OV_HW_1, REQ_DEV_OV_QS_1, REQ_DEV_GUIDE_QEMU_1, REQ_DEV_GUIDE_MODES_1, REQ_DEV_GUIDE_DEBUG_1, REQ_DEV_GUIDE_FLASH_1, REQ_DEV_ENV_1, REQ_DEV_LIMITS_1, SPEC_DEV_OV_INDEX_WHO

Role: Developer Story: As a developer, I want README, overview pages and guides to be linked to the specs they describe, so that when a spec changes, supporting docs are automatically in the change impact scope — including which development environments are supported and what known limitations exist. Value: Without traceability, supporting documentation silently goes stale when specs change. A developer setting up for the first time needs to know which environments are supported (devcontainer / Codespaces — not Windows) and where to find known limitations, without discovering them by trial and error.
