Current evaluation

SNAPCRAFT_BUILD_ENVIRONMENT was overriding the --use-lxd CLI flag; CRAFT_MANAGED_MODE precedence is intended per maintainer. Fixed by merged PR #4329 (commit 7f8d4cff9) which prioritizes the flag; issue remains open and can be closed.

Suggested action: close stale

Reason: The bug portion is fixed: merged PR #4329 (commit 7f8d4cff9, 'cli: prioritize --use-lxd over SNAPCRAFT_BUILD_ENVIRONMENT') is in current HEAD, and get_provider() now checks the CLI-provided provider before the env var. The maintainer also confirmed in a comment that CRAFT_MANAGED_MODE behavior is correct, so the original problem is no longer reproducible and the issue has been inactive for ~7 months.

#1841892 snapcraft options are position-dependent snapcraft (launchpad) open Reports snapcraft CLI flags are position-dependent: `snapcraft --use-lxd build` silently ignores the flag while `snapcraft build --use-lxd` works. Unanswered for ~7 years; `--use-lxd` was later removed from snapcraft, making the example obsolete.
