Chisel slice install errors are swallowed when log level is info or higher, so users see no chisel output or error message. Triaged bug with an internal Jira ticket (CRAFT-4872); no fix or maintainer response yet.

Suggested action: keep open

Reason: The issue is labeled Status: Triaged and Type: Bug, and a maintainer (lengau) filed it with a reproducible part yaml, so it is a valid, acknowledged bug that should stay open. The only activity is the Jira sync bot (CRAFT-4872), with no fix or further discussion in ~10 months, making it moderately stale but still relevant. The code path in craft_parts/packages/deb.py _unpack_stage_slices captures chisel output via a logger StreamHandler and raises ChiselError, so the fix is likely localized to how that output is surfaced at info+ log levels.
