Release v0.3.0

Title: Embedded firmware foundation and project UX

Status: Completed

Milestone: V0 software companion foundation

Version architecture: Architecture for v0.3.0

Archived records

The release delivered seven epics, E17 through E23, and twenty-two PBIs, PBI-064 through PBI-085. The bug register closed empty again. LIM-005 and LIM-010 were resolved during the release and remain only in this archive, LIM-003 and LIM-012 were narrowed, LIM-013 was opened, and eight limitations carry forward.

Identifier continuity

Identifiers do not restart after this release. The next active epic, PBI, bug, and ADR identifiers continue from the highest identifiers used before or during this release.

Release evidence

Evidence for the release claims is recorded in evidence.md and in section 10.5 of the version architecture. The verified toolchain is recorded in both places. The exit criteria are ticked in section 6.4 of the milestones document.

The hosted claim is build and runtime evidence on Linux under GCC and Clang. The embedded claim is cross-compile evidence for the classic LILYGO T-Display as ESP-IDF esp32, and it is not a hardware runtime claim.

Notes

• ADRs remain in docs/adr/. ADR-008 through ADR-011 were accepted during this release.
• Version architecture remains in docs/arch/arch-v0.3.0.md.
• Active planning continues in the root planning documents, which continue at E24 and PBI-086.
• These files are historical records. Edit them only under the rules in section 9 of the release process.
• The archived files keep their rollover content unchanged. Only their relative link paths were re-pointed so they resolve from this directory, which section 9 permits as a broken link fix.
• No git tag or frozen branch was created when this archive was written. Tagging v0.3.0 and creating release-v0.3.0 remain maintainer steps under section 7 of the release process.
