Architecture decisions

NovaFabric records every architectural decision as a numbered ADR (Architecture Decision Record). This page is the canonical index: whenever the documentation cites ADR-0123, this table is what it refers to.

Why only an index? ADR bodies are internal design records — they carry in-progress research, competitive analysis, and commercial reasoning alongside the technical decision, so the project publishes the decision ledger rather than the deliberation. Everything an ADR decides that affects you as a user or contributor is reflected in the code, the CHANGELOG, the ROADMAP, and the docs in this directory. If a decision here matters to something you are building and the public docs do not explain it, open a Discussion and ask — we will write it up.

Proposing a change to a decision is the RFC process, not an ADR. RFCs are public and live in docs/rfcs/.

Status Meaning
accepted Decided and in force.
proposed Written, not yet decided.
superseded Replaced by a later ADR.
rejected Considered and declined; kept as provenance.
