fixtures: golden data dir — real records, production read paths
Owner-manufactured teach master (chat_mv27rrra: compaction, subagent-abort, every teach tool) + practice lifecycle (chat_mv293wv5: the full marker cycle including the first-ever problem-dismissed), the real graph ledgers, five jobs across the kind x status matrix, and settings. tests/golden-fixtures reads all of it through the stores via the LH_DATA_DIR seam and pins the fixture law: real data parses, flattens to a legal LLM wire, derives the graph, covers every custom-marker kind, and reads never write. Fixture law: an intentional format change updates these files in the same commit; an unintentional one fails the suite.
