Overview

GoDepResolver handler - second-pass resolver that patches dependsOn relations onto ApplicationComponents generated by GoGrapher.

Runs after all GoGraphers complete (iteration 2 of the executor loop) so the database contains the full set of freshly-generated ApplicationComponents. Output goes to a single shared generated/relationships.yaml file (all repos combined), loaded after modules.yaml alphabetically so its version of each component — with dependsOn — takes precedence.

One Import:GoDepResolver:* resource is emitted by each GoGrapher run; this handler is registered as a child of GoGrapher via the generates relation so the executor knows to wait until GoGrapher has completed.

Configuration:

import/config/path - Path to the Go repository root (same as GoGrapher)
