search_bot conflated MAXTHREADS into two jobs at once - how many chunk files to
read (files 0..MAXTHREADS-1) AND how many producer sentinels to wait for - so
the two had to match exactly. Set too low it silently skipped trailing chunks;
set too high (or with any chunk missing/unreadable) a producer crashed before
emitting its sentinel, the consumers' count never reached the threshold, and
search_for_doi hung on join() forever. The idle-timeout failsafe that was meant
to break a starved consumer was dead code: `if empty_counter > 5: ... elif
empty_counter > 10: break` - >10 implies >5, so the elif never ran.
Fix, three layers:
* auto-discover the chunk files present (discover_chunk_files: <n>_chunk.txt in
numeric order) instead of range(0, MAXTHREADS). All files are read regardless
of count, and no producer is ever pointed at a missing file;
* the sentinel threshold is now the number of producers actually started, so it
can't drift from what's emitted;
* producers emit their sentinel in a finally, so even a crash (missing/unreadable
chunk) can't starve the count; and the idle backstop is reordered so it can
actually fire (>EMPTY_LIMIT seconds) as a last resort.
MAXTHREADS is deprecated and unused (kept only so old env files don't break);
docs/env updated to say chunk files are auto-discovered.
For the reported case (MAXTHREADS=40, files 0..43): before, files 40-43 were
silently never searched, and any run that referenced a missing chunk hung
forever. After, all 44 are searched and it always terminates.
Verified in a pytest-only venv (tests/unit/test_search_bot.py): DOI in a
trailing chunk is found; an unreadable chunk still terminates; empty dir returns
at once; discovery is numeric-sorted. Full unit job 27 passed.

(Re-applied cleanly on top of main: PR #18 was rebase-merged, so the branch
that became #19 conflicted on the already-landed commits. This carries ONLY
the librarian state fix - the sole content difference between that branch
and main - so nothing else is touched or lost.)
The worker threads open cr_results/rr_results/not_in_db/s_results.json in
place ('r+'), crashing with FileNotFoundError in a fresh container. New
conjurer_librarian/lib_paths.py resolves all four under a persistent dir
(CONJURER_LIBRARIAN_STATE_DIR, default /lib_temp_files) and seeds missing
ones with '{}' on import; shared by conjurer_librarian.py and scrape_bot.py
(no circular import). ndb_database/database initialised to {} before load so
a corrupt persisted file degrades to empty instead of NameError. search_bot
/search_bot2 open the DOI DB 'r' not 'r+' so /doi can stay read-only. Docker:
STATE_DIR env + VOLUME, compose mounts /srv/librarian/state:/lib_temp_files.

Containerises the three services (each intended for its own Proxmox VM)
and adds the code changes needed to run cleanly on Linux/Docker.
Code fixes:
- constants.py: CONJURER_DATA_DIR roots all writable bot state under one
mounted volume (per-variable overrides still win; native Pi unaffected)
- conjurer_librarian/search_bot.py + scrape_bot.py: the hardcoded Windows
DOI database path (C:\Database\chunks\) is now CONJURER_LIBRARIAN_DB_PATH,
with CONJURER_LIBRARIAN_MAXTHREADS / _CHUNK also env-overridable
Docker:
- docker/Dockerfile.{bot,librarian,musician} + compose.{bot,librarian,musician}.yaml
- docker/env/*.env.example (force-added; real *.env stays gitignored)
- docker/entrypoint.bot.sh seeds default JSON state into /data only when
absent, so preserved history is never overwritten
- .dockerignore
- docs/deployment/DOCKER_PROXMOX.md: step-by-step runbook incl. preserving
the existing command/conversation history and cross-VM auth
The bot image uses the vendored yt_dlp/spotify_dl forks (they win on
sys.path over the pip packages), dropping the old sed patching.
