hive_contract reads an interior edge to `.` as an ENTRY into the hive and refuses a live add_edges the boot only warns about

[mmeyerlein]

What happens

A live mutation that draws an edge from an interior node of a sealed hive to the hive's own root — add_edges with to: "." and a constant set_hop: {"route": "error"} — is refused by the hive_contract validator:

sends hop.route='error' into hive <member>, which does not accept that lane

The very same edge ships in templates/member (the catch-all ./channels -> . on error, GH #598) and instantiates at boot with a warning at most. So the boot path and the mutation path disagree about one edge: an edge from inside a hive to . is an exit (the message leaves through the hive's rim), but the validator reads it as an entry into the hive and checks the hive's accepts list against it.

Measured (2026-09-06, GH #598 rewire of two running colonies)

• Test agent e20 (meclaw 0.31.0 + apps rim, member marcus) and the demo colony (member demo): the remove_edges half of the Endless loop that costs money: display invalid_view receipt → in_turn (kind receipt) → assistant answers in prose → display refuses again (44 brain calls in 6 min) #598 fix (drop the receipt -> in_turn re-stamp) committed on both; the add_edges half (widen ./channels -> . to carry receipt out on error) was refused with the line above on both.
• Consequence: until those instances are rebuilt, a screen receipt that no app owns is a dead letter there instead of an error message leaving the level. The loop is gone either way (the text-turn proof ran at 3 resp. 4 brain calls), but the two colonies do not carry the shipped topology.

Ask

hive_contract should classify an edge by direction the way the router does: from interior, to == "." (or the hive's own path) is an exit and is checked against emits, not accepts. A regression test: the shipped member catch-all edge, applied as a live add_edges to a grown member, must commit, and the same body must still be refused when it truly enters a hive that does not accept the lane.
