Why: The three libraries cannot be reused or recovered independently, and the tested dependency combination is not the one the product builds.
Evidence: Read-only audit at native c6d867c, squad 590fd86, intent 1dbbe81, recorded with file references in docs/records/2026-10-02-agent-stack-audit.md.
Impact: Documents only. No library code or gitlinks change in this commit. Later stages stay separate tasks.

Why: Tool-call history is flattened into assistant text, so the model imitates calls and invents artifact ids. The fix belongs to a shared harness, not another prompt tweak.
Evidence: Proposal 2026-10-01-agent-harness.md records the 2026-10-01 session evidence, the ZCode and Claude Code patterns, and the P0-P4 acceptance.
Impact: Documents only. P0 code lands in the backend on the same branch name. P1-P4 are not implemented here.

Why: The base must stay unmodified by downstream products, so the roadmap, compatibility window, and plugin contract need a written proposal before further forks.
Evidence: Three proposals under docs/proposals and a short pointer in the plugin development guide.
Impact: Downstream work follows extension-point requests and a published base version. Tag commands in the compat proposal are not executed.
