-# This Plugin carries three review rounds of confidentiality, containment and
-# bounding fixes, and each round ended with the same finding from the reviewer:
-# "current tests do not cover the reproduced cases". The three fixtures that should
-# have caught them existed and were green.
-#
-# So this workflow does not re-run the repository's own `npm run check`, which
-# already covers `scripts/validate.mjs` and the whole test tree on ubuntu. It adds
-# the evidence that has been *claimed* rather than checked for this Plugin:
-#
-#   contract   The plugin-scoped gates: the release gates, then the egress contract
-#              suite that drives every tool and every route against the real
-#              projection instead of a stub store. The `/api/overview` 500 survived
-#              two rounds precisely because only stub stores exercised that path, so
-#              the stub-free suite is run as its own named step rather than folded
-#              into a count.
-#   suite      The full Plugin suite on ubuntu, macos and windows. Cross-platform
-#              evidence was previously a hand-run claim; the previous hand-run had
-#              not covered three platform assumptions in the tests themselves.
-#   engines    `tools/compat-matrix.mjs` under the documented Node floor, the lowest
-#              verified release and the current line, so the manifest's floor and
-#              verified range are asserted rather than described. On a release
-#              outside the verified range the only permitted skip is the FTS5 search
-#              test, and the tool fails if anything else is skipped.
-#
-# Scope is deliberately narrow: `paths:` filters this workflow to the Plugin plus
-# this file, so it can never block an unrelated PR. See the note in ci.yml about
-# why an unscoped "validate everything" job was removed there.
