Three rows in ingest_failures were Office lockfile leftovers whose
filename starts with ~� (~ followed by the UTF-8 replacement
character) instead of ~$. Somewhere in the Nextcloud sync chain the $
byte was lost or replaced; the file now lives on disk as a real file
with this corrupted name. The watcher's ("~$", ".") prefix filter
didn't match, so each cycle tried to ingest these as pptx, hit
BadZipFile inside python-pptx (lockfiles aren't real Office documents),
and they ended up permanently in ingest_failures.
Three filter sites in watcher.py applied the lockfile prefix check:
- ingest_file() at :127
- get_changed_files() at :200
- IngestHandler._should_ignore() at :290
All three now match ("~$", "~", ".") — broadened to catch any tilde
prefix, not just ~$. The cross-check against pgvector embeddings and
disk found zero legitimate tilde-prefixed files in the corpus, so the
broader filter has no false-positive risk in this corpus.
Cleanup: 3 ingest_failures rows resolved (filepath LIKE '%/~%').
Unresolved count drops 97 → 94.
If a fourth filter site is ever added, the right shape is consolidating
the lockfile prefix check to a shared function or constant. Three
parallel sites with three different tuple orderings is acceptable for
now but worth normalizing if the surface grows.
