This is the only way Renovate can honor minimumReleaseAge with uv: given floor ranges (>=), `uv lock` resolves the floor to the NEWEST in-range release — which may still be too fresh — and Renovate cannot pin uv to an exact aged version (renovatebot/renovate#41624), so it fails the artifact update instead of waiting (this stalled #816). Pinning writes the exact aged version into pyproject.toml, so uv can't overshoot and the age gate is respected. shapepipe is deployed as a container and is not published to PyPI (an application, not a library with downstream installers), so pinning is the appropriate, standard choice; the abstract-floors design in CLAUDE.md targets libraries, which this isn't. Renovate opens a one-time 'Pin dependencies' PR. NOTE: this gates DIRECT deps only — transitive deps in uv.lock still float to latest via lockFileMaintenance.",
