An intent's blocked_by edges are read by the build gate (internal/core/intent/startcheck.go, startBlockedRow, and the implement loop's check) but no verb writes them: abcd capture link adds and removes blocked_by on an issue, and abcd intent has no counterpart (its link sub-verb links a spec), so a downstream project hand-typed every edge between its intents.

Grounds

• pursued: a person can now link two intents with one command and the build gate refuses the blocked one; shown wrong if an edge written by the verb is not read by startBlockedRow or record-lint refuses a record the verb wrote
