- CI installs the backend requirements from docsgpt/; the old cd into
application/ silently installed nothing.
- The root .dockerignore re-admits only application/__init__.py. An upgraded
checkout may still hold gitignored application/{inputs,indexes,vectors,.env}
from the old layout, and the directory rule shipped them into the image.
- The compose files keep the host bind mounts on application/{indexes,inputs,
vectors}, so an upgrade does not start with empty data. The move comes with
the packaging work, together with an upgrade note.
- The alias loader puts the real docsgpt spec back on the shared module object
after import (the import machinery stamped the alias spec on it, which made
importlib.reload rename the module and skip re-execution) and delegates
get_code/get_source/get_filename to the target loader, so
python -m application.<name> runs.
- Each legacy application.* task name is registered as its own task object,
a subclass carrying the old name. Registering the same object under two
keys made Celery's tracer log every run under whichever name it built last.
- The redbeat key prefix stays redbeat:docsgpt:; the three schedule_syncs
entries get stable names instead. redbeat tracks its static entries and
deletes the ones that vanish from beat_schedule at start-up, and rewrites the
task path of named entries in place, so neither a prefix bump nor a cleanup
pass is needed (checked against redbeat 2.4.2 with a seeded Redis).

"""``application`` is now ``docsgpt``; this alias keeps the old name importable for one release.

Every ``import application.x.y`` resolves to the already-imported ``docsgpt.x.y``

module object, so there is exactly one settings object, one Celery app and one

Flask app however a process refers to them. Entry points such as

``celery -A application.app.celery``, ``uvicorn application.asgi:asgi_app`` and
