Architecture Decision Records (v0.5.0)

Contiguous ADR sequence for decisions that remain part of the shipped / current v0.5.0 product architecture. Superseded tooling pins and post-0.5.0 roadmap ADRs are not retained in this tree.

Numbering

ADRs are numbered NNNN-slug.md starting at 0001. Accepted ADRs are immutable; a new ADR supersedes an old one rather than rewriting it.

Published Starlight nav: Engineering → Architecture Decision Records (sidebar entries mirror this table). ADR bodies stay under docs/adr/; the public decision log at ../engineering/adrs/ links here and must not duplicate or renumber bodies. Do not fork a second ADR sequence.
