morlutoandCursor Agent 31278c7b5a fix!: qualify call paths by provider discovery (#8443)
* fix!: qualify call paths by provider discovery

* fix: preserve compact call coverage schema guidance

* fix: preserve call discovery reasons in path evidence

* fix(evidence): retain discovery limits in call verification

* test: declare discovery in reconstruction controls

* fix: preserve call discovery across facet limits
