Separate connected-pocket volume from the %V_bur complement.
The flood fill excludes empty voxels that are disconnected from the centre. --exclude-self --vbur counts all occupied points in the sphere and defines free volume as tot_vol - occ_vol, so disconnected empty voxels remain included. Describe the flood-fill result as connected-pocket volume, or remove the connectivity restriction if equivalence is required.
Suggested wording fix
-- **Sphere-bounded (consistent with %V_bur):** empty voxels within radius R that are connected
+- **Sphere-bounded connected-pocket volume:** empty voxels within radius R that are connected
to the centre by a flood fill through empty space (`scipy.ndimage.label`). Disconnected gaps
- behind residues are excluded. Free volume is the complement of what `--exclude-self --vbur`

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

docs/plans/void-featurization.mdcollects the design discussion on describing pockets and active sites with DBSTEP: how a void gets a centre, a boundary and an orientation from the existing occupancy grid; three families of vector/tensor representations (aligned free-space tensors with residue-class channels, rotation-invariant spherical-harmonic and radial × angular power spectra plus Zernike invariants, and an interpretable slice matrix along the mouth axis); design constraints (normalisation, grid resolution vs harmonic degree, ensembles, hydrogens, waters); where each piece would live in the code with no new dependencies; a validation plan built on synthetic cavities with exact answers, rotation tests and the bound-ligand fit check; and a suggested order of work.Summary by CodeRabbit
