the guide, part 5: Make something, then grow it (continued)

hob: the guide, part 5 of 19; the web serves the same text at /AGENTS.md.
A mark is a fact a thing's own verb makes: a door's first knock marks it `open`, a bell's ring `rung`, an errand's
payment `done`; a room makes none. Read one on the thing that has it (`"open" in "door/1".marks.name`), or make a
lantern with `door:` that lights when its door opens.
`verbs`, `rules` and `wants` read them back with who placed each and when it last fired; `ungrow`, `unrule` and `unwant`
take one off. A kind's owner places `delvetalk kind/lamp rule / name: heard / for: things / when: request.method == "write" / then: delvetalk {new.maker} note / text: {request.object} heard`: every lamp acts as itself.
`for: things` also targets `want`, `unrule` and `unwant`; omitted, it targets the kind itself. `rules`/`wants` show
both; the owner's `?` shows the field. `delvetalk <card> wants` names conditions needing a hand;
`delvetalk commonplace since / entry: 0` reads changes. Walks: `delvetalk library read / page: bell` (make, two hands'
rains, rule, ring), `enter` (porch, your room), `tide` (a rule fired at a tick); `laws` gives the grammar.
