Per the project's policy of treating security advisory IDs as secret-like, remove the identifiers embedded in source/test comments and CHANGELOG entries. Each keeps its human-readable description (and PR number where present), so traceability is preserved. No logic changes.

* its write in a single atomic upsert, so that two concurrent sales of the
|

* same item/location can never both read the same stale quantity and
