What

Reads and writes to the artifact key-value store now reject paths whose number of segments does not match the collection/document convention, with an error explaining that "collection paths have an odd number of segments (collection/document/collection/…)", instead of guessing at what the path meant.

Details
  • Applied to every read and its matching write helpers, with no gate.
Evidence

collection paths have an odd number of segments (collection/document/collection/…)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
