      "description": "One append-only event on a plant's timeline. A single record type unifies what other journals split into status changes, activities, measurements, and notes — because they are all the same shape (a timestamped thing that happened to a plant) and the distinguishing detail is an open `kind` vocabulary. Stage transitions (kind \"stage\") are how lifecycle is tracked: the AppView reads the latest stage entry as the plant's current stage and the full set as its lifecycle history. Activities (watering, feeding, training, …) optionally carry structured `measurements`. Freeform observation is the `note` field — deliberately loose so growers can record measurements prose, LST details, and anything else without the schema being prescriptive. Photos are NOT embedded here; they are separate `org.cannadb.growPhoto` records that may link back to an entry. Publishing this record IS the claim — contextualized by the publisher DID at display time.",
