Folds Filbert's N1 per Sage's comment 28355: the envelope test sends a role cap with a tester proof. The narrowing mutant at server.mjs:50 survives the full bus suite on round 1 and is killed on round 2. Full gate passed with the real bwrap tester case running.

# Row 110 round 2 (#1604), Sage's ask in comment 28355: the narrowing mutant.
|
||
# server.mjs:50 refuses an envelope that carries more than one of cap, human and
|
||
# tester. The mutant narrows the conflict check so a cap counts only when it is
|
||
# alone or is a reader cap (role null, not human). A role cap sent with a tester
|
||
# proof then passes the envelope and the request runs as the tester.
|
||
# Runs the FULL bus suite (node --test tests/*.test.mjs in packages/bus), not
|
||
# one named test. Restores server.mjs from the .orig copy whatever happens.
