Debcraft snap FTBFS on riscv64: pydantic-core lacks a riscv64 wheel, forcing a source build that needs rustc. Triaged as a bug; fix expected once pydantic ships riscv64 wheels (pydantic/pydantic#12723). Lock file still pins pydantic 2.11.9.

Suggested action: keep open

Reason: The issue is labelled Status: Triaged / Type: Bug and has a clear root cause: pydantic-core has no riscv64 wheel, so the build falls back to a rustc source build that fails. The last comment (166 days ago) points to pydantic PR #12723 adding riscv64 wheels in the next release, making this blocked on an external dependency rather than stale or unactionable; uv.lock still pins pydantic 2.11.9, so nothing has been fixed in-repo yet.
