Eight proposals grouped by category, each with problem statement, concrete plan, and risks: property-based testing over the protocol-shaped core (chunk streams, event logs, schema DSL); mutation testing as the counterweight to the 100%-coverage gate; deterministic tests + a universal replay-invariant fixture + nightly race stress; architectural conformance (dependency-cruiser rules and the LlmAdapter conformance kit); runtime arg validation at the model boundary with a structured error taxonomy and dev-mode invariants; doc-sync enforcement (typechecked doc snippets, API reports); supply-chain checks and nightly vendor-drift verification against the manifest; and deep-readonly public surfaces (logged-vs-in-flight mutability boundary). AGENTS.md points at docs/adr and docs/rfc.
RFCs
Proposals for substantial future work — reviewed before implementation, unlike ADRs (which record decisions already made). Each RFC groups a related set of ideas from the quality/robustness proposal (2026-06-11); statuses move proposed → accepted → implemented (then usually graduate to an ADR).
