Companion to website#171.
ENGAGEMENT.md gains an "As built - 4b" section: the four decisions the org lead
settled, the correctness argument behind the standalone enable route, the three
honesty fields on the reach preview, and the two defects the live walk found in
Phase 4a's own code (a rule pointing at a dormant segment reading as healthy,
and the delete refusal's "1 rule still use"). It also records the throwaway
module rig that made the whole segment half walkable at all - core declares no
audiences, so on a stock local stack none of the §5.1a arithmetic can be
exercised without one.
§5.1a gains the composition UI it was owed: its own nav entry rather than a tab,
"exclude" offered only under "all of", the stored ceiling displayed and never
chosen, and a tree nested deeper than the composer renders shown read-only
rather than flattened.
BACKEND_DESIGN.md's route table gains the twelve routes, including why the
enable switch is a PATCH of one column and why deleting a segment in use is a
409 rather than a cascade.
