#1537 shipped with a manual test checklist only. Add automated tests that corrupt a graph.json and assert the actionable RuntimeError at all three load paths (build_merge, affected.load_graph, diagnostics._read_json_file) plus a happy-path guard. Also record the six merged small fixes in the changelog. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

"""Corrupt graph.json produces an actionable error, not a raw traceback (#1536/#1537).
|
|
|
|
Three load paths call json.loads on graph.json — build_merge (`--update`),
|
|
affected.load_graph (`graphify prs`), and diagnostics._read_json_file
|
|
(`graphify diagnose`). A truncated / invalid file (incomplete write, power loss,
|
|
manual edit) must raise a clear RuntimeError with recovery guidance at each.
