- snapshot: depth limit (stack overflow in exporters), decompressed-size
limit (gzip bombs), per-node size cap and saturating aggregation
- export: sanitise exclusion patterns from snapshot metadata
- tui: drop duplicate/trash/filter results that belong to a replaced
tree; cancel duplicate search on rescan
- trash: refuse symlinked or foreign shared-filesystem trash dirs; never
overwrite an existing trashed item
- scan: no symlink following without inode identity; correct unscanned
count and keep real read errors after cancellation
--compare opens the TUI with growth/shrink colouring unless a report is
requested. treegen builds deterministic synthetic trees (Unicode,
hostile names, sparse files). MAPSIZE_DEBUG_PANIC verifies terminal
restoration on UI and scanner panics.
