`msmu.dt.drop`

Delete a metadata entry or table column in place, recording its location for replay.

target is uns, obsm, varm, a modality-specific equivalent, or a table path accepted by map. A mapping target deletes its key; a table target deletes a column, so <modality>.decoy removes a decoy-table column while <modality>.uns with key="decoy" removes the whole table. Missing keys raise KeyError. Returns the same MuData; provenance and global modality masks cannot be deleted.

Parameters:

Name	Type	Description	Default
`mdata`	`MuData`	`MuData` to modify.	required
`target`	`str`	Metadata mapping or table path.	required
`key`	`str`	Entry or column to delete. Missing keys raise `KeyError`; `_log` and global modality masks are protected.	required

Returns:

Type	Description
`MuData`	The same `MuData`, modified in place.

Examples:

import msmu as mm
mdata.uns["temporary_note"] = "reviewed"
mm.dt.drop(mdata, target="uns", key="temporary_note")
