"""Pin the security fixes from the 2026-05-19 session so they don't regress:
|
|
|
|
- `src.secret_storage.encrypt/decrypt` round-trip, idempotent on already-
|
|
encrypted input, transparent on legacy plaintext, fail-soft on bad key.
|
|
- `routes.email_helpers._q` quotes IMAP mailbox names so a folder named
|
|
`"INBOX" (BODY ...` (or one containing `\\`) can't terminate the IMAP
|
|
command early.
|
|
- Compose-upload tokens flow through `pathlib.Path(token).name` so a
|
|
caller supplying `../../etc/passwd` can't escape `COMPOSE_UPLOADS_DIR`.
|
|
|
|
These are pure-function tests — no FastAPI app boot, no DB.
