Architectural decision records

This directory records consequential qslib design decisions and their rationale. Use an ADR when a choice is difficult to reverse, changes public semantics, introduces a major dependency, establishes a cross-cutting abstraction, or affects interoperability with another project.

Copy 0000-template.md and assign the next four-digit number. Keep one decision per file. Use one of these statuses:

• proposed
• accepted
• superseded by ADR-NNNN
• rejected

An ADR does not override docs/conventions.md silently. A decision that changes a scientific convention must update the convention schema and the normative document explicitly.
