epistemic-gardening

Use when the user says '/epistemic-gardening', 'garden the graph', 'de-weed', 'prune artifacts', 'epistemic hygiene', 'clean up findings/goals/sources', 'graph hygiene pass', or 'pre-release cleanup'. A PRAXIC pass that de-weeds a practice's epistemic graph — resolve stale/superseded findings, close answered unknowns, verify or drop assumptions, archive done goals and stale sources, prune dangling edges — so retrieval surfaces what's live, not what's rotted. Includes the mesh-wide propagation pattern for getting every practice to garden.
