The platform now has `scope: 'shared'` for a dependency every account must be able to run, and the
check that goes with it — world-executable, and every parent directory traversable.
iris cannot use it yet, for a reason worth writing down rather than rediscovering: it BUILDS its
binary in the sidecar rather than declaring it as a dependency, so there is nothing for the probe to
judge. The remaining half is this sidecar installing into /usr/local/bin.
Also corrected open item 3, which said a member's agent "cannot read it there". On alpha it can —
/home/<owner> is mode 751, so an absolute path traverses. That is an accident, not a design, and 750
would break it silently. Stated that way so nobody concludes it already works.

Designed 2026-08-20 in conversation; PLUGIN.md is the decision record. Nothing here has
run yet: no live install, no build, no capture. The wrapper's two launch branches and the
cookie-seeding are written against documented behaviour, not observed behaviour.
