Summary

Per Lucy's #1055 review (item 1): the bare except Exception: on read-quota.py:26 masked a path off-by-one for half a day — any unexpected error set _canonical = None and printed the misleading "not found" message instead of surfacing the real failure.

The only anticipated failure at this call site is ImportError (workspace_default not importable because sys.path is wrong). Narrowing to ImportError:

• Lets AttributeError, TypeError, disk errors, and any other unexpected exceptions propagate to the caller
• Makes silent fallback failures visible instead of swallowing them

Change

# Before
except Exception:
    _canonical = None

# After
except ImportError:
    _canonical = None

One line changed. No behavior change for the normal path or for missing-module installs.

Test plan

• python3 skills/quota-tracker/scripts/read-quota.py on a machine with workspace_default importable → same output as before
• On a machine where the import fails → same "not found" message (ImportError still caught)
