- redownload now ALWAYS rebuilds into a fresh private asset instead of ever reusing a shared
cached file: the cache sig is salted with job_id + current asset_id, so the fork is distinct
from both the dedup pool and the job's own current asset. This resolves the co-held silent
no-op (finding #1) — a shared asset is left intact for its other holders while THIS job
re-fetches its own copy. Resolving the fork BEFORE releasing the old hold (and the unique
salted key) also removes the IntegrityError-rollback-after-file-delete window (finding #2).
- format_sig gains an optional `salt` for that fork identity.
- titles: don't consume the space after `|`, so a "stats | #hashtags" remainder keeps the
leading whitespace _TRAILING_HASHTAGS needs — and fall back to the prefix+hashtag-stripped
text, so neither the stats nor the SEO hashtags are resurrected when a title empties (#3).
- worker: early-fill asset.title falls back to the video id so a title that cleaned to empty
doesn't show a blank card while downloading (#5).
- Tests for the salt fork and the hashtag-remainder case.
(Finding #4 — quota on re-download — intentionally not changed: a re-download reuses the
existing job and re-fetches ~the same bytes, so calling check_enqueue would wrongly reject on
the job-count cap while footprint is unchanged.)
