Checked ADR-002 part 2's deferred question against the two observability
additions that landed since (rein-aharness's tool-event stream,
glas-harness's own gateway hub event) -- both turned out simpler as
direct implementations, neither needed a wrapping middleware layer.
Still zero real candidates for that shape. docs/harness-contract.md
gains the Middleware ABC as a documented, unimplemented sketch for if a
real third case ever appears -- no code written now.
Also flagged GLAS-WP-0002-T02 (live OpenBao verification) as blocked:
`bao token lookup` from this workstation returns 403, no usable vault
session to provision a new AppRole with. Needs the operator.
