The archy content latch was global and permanent: once mount-time content
latched archyContentActive, no extracted [[film_ext:…]] recommendation card
could ever render again, and an empty tool result kept the latch — so a
'recommend me films' turn beside an empty catalogue showed prose only, with
'Nothing found' overwriting nothing. The chat had lost its rich previews.
- setArchyContent records which buckets the node actually supplied
(archySupplied) and latches active only on a non-empty delivery
- updatePanelFromText's no-overwrite guard is now per-bucket: node truth
wins buckets it filled; empty buckets stay writable for extracted previews
- the extraction fallback title no longer clobbers 'Nothing found'/'Loading…'
Regression tests: previews render in an empty bucket, node truth survives
tags in a filled bucket, 'Nothing found' survives a both-empty turn.
