What

A shared claim-once registry replaces the assorted booleans and sets that each warn-once site kept for itself, so repeated diagnostics are suppressed the same way everywhere.

Details
  • Callers now include the MCP tree-id tripwire under the key mcp_tree_id_tripwire, bare-primitive tool-result warnings keyed per tool, tool search, ink tree depth, frontmatter shadowing, the advisor unranked-base-model warning and the gateway retention sweep permission warning.
  • One dialog class dropped its own claim and reset pair in favour of a simple marker method.
Evidence

mcp_tree_id_tripwire, advisor_unranked_base_warning

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
