Summary

autonerves.workspace.check_version runs on every import of autofit / autogalaxy / autolens with workspace_root defaulting to the current working directory. Running a plain script from a data directory (no workspace at all) found no version floor and warned "Cannot verify the workspace ...". The no-floor branch now returns silently when the directory has no config/ (new _looks_like_workspace) as well as for package source checkouts. A directory with a config/ but no version keys and no version.txt (a misconfigured workspace) still warns. There is deliberately no walk-up to a parent directory.

Reported by external contributor @HRSAstro in https://github.com/orgs/PyAutoLabs/discussions/13 (comment PyAutoLabs/.github#13 (comment)).

Closes #191.

API Changes

None to the public API. One behaviour change: check_version no longer warns in the no-floor case when workspace_root has no config/ directory.
See full details below.

Test Plan

• New test test_missing_sources_without_config_dir_is_silent fails on unfixed source (red), passes after the fix
• New test test_config_dir_without_general_yaml_or_version_txt_warns passes (the misconfigured workspace still warns)
• test_missing_sources_warns now creates config/ first and still warns
• Full autonerves suite: 241 passed
• Live check: python -W always -c "import autofit" from a bare dir prints no warning; after mkdir config it warns once

Full API Changes (for automation & release notes)

Added

• autonerves.workspace._looks_like_workspace(root) (private): (root / "config").is_dir()

Changed Behaviour

• autonerves.workspace.check_version: when no floor is found (no config/general.yaml version keys, no version.txt), it returns silently if workspace_root is a source checkout or has no config/ directory. Previously only source checkouts were silent.
• Side effect: autofit_workspace_developer and autolens_workspace_developer have no config/ and no floor, so running from their roots no longer emits the warning. Neither repo records a floor, so nothing was being checked there before either. Every other workspace root ships config/ and is unaffected.

Migration

• None. Nothing asserts the warning text: Heart, Hands and PyAutoLens subprocess tests only set PYAUTO_SKIP_WORKSPACE_VERSION_CHECK=1.
