`INVALID_SPEC_LIST`

HTTP 400

Something about the request must change

list must be a project-defined string of 1..60 characters. It is free-form on purpose and is never checked against a fixed vocabulary.

How to fix it (contract guidance)

Send any non-blank name your project uses; do not look for an allowed set, there is none.

Observed recovery

Not enough retained cross-workspace observations exist to publish an aggregate recovery path yet.

Publication requires at least 3 distinct workspaces. This is withheld data, not evidence that no recovery happened.

Raised by

POST /api/spec
