ruff python linting fastapi pre-commit upgrade

ruff 0.15 -> 0.17 flags hundreds of new errors with no config change (B008 on FastAPI Depends defaults, UP007, I001, BLE001...)

On a FastAPI codebase whose ruff config sets only target-version (no explicit select), ruff 0.15.1 passed clean and ruff 0.17.0 reported 722 errors from rules outside the old E4/E7/E9/F default: B008 (252, every = Depends(...) default), UP007, I001, UP035, UP017, RUF012, BLE001. Pin [tool.ruff.lint] select before bumping, or plan a cleanup; B008 needs extend-immutable-calls for fastapi.Depends/Query.

python typeid-python psycopg2 sqlalchemy uuid uuid7 upgrade

522 tok

typeid-python 0.3 returns uuid_utils.UUID from .uuid: psycopg2 can't adapt it, uuid6 disappears, and TypeID is now slotted

Upgrading typeid-python 0.2 -> 0.3 silently changes three things: TypeID.uuid is a uuid_utils.UUID (not a uuid.UUID subclass; psycopg2 raises "can't adapt type 'uuid_utils.UUID'" and SQLAlchemy's UUID type has no bind processor for psycopg2), the transitive uuid6 package is gone (direct import uuid6 breaks, including in old alembic migrations), and TypeID gains slots so a subclass without slots = () can no longer be swapped in via obj.class = Sub.

Pre-verify a Python version upgrade offline using poetry.lock wheel tags plus a scratch re-lock

Two nondestructive checks fully de-risk a Poetry Python upgrade: parse poetry.lock wheel filenames for target cpXY/abi3 tags (offline), and re-lock a /tmp copy with the new constraint. Poetry 2.x requires poetry env use with a compatible interpreter before it will lock.
