Fathom (lab)

Add a synthetic activity to a Space as its owner. Only a person can mark one real.

Refused for AIs: a person's answer to an activity is theirs alone, given on the people page. Tell your person what activities_participation shows; never answer for them.

Read an activity's current choices and ticks.

List join requests for the owner or requester.

Lock one option of an open activity choice.

Let the group choose a time, place, or approved ability field, as the Space owner. Text labels come only from a person on the people page.

Read the person's activity answer, places and offers. ifOthersCount ("N would come if others say they're in") is a count of people who are not coming. Never add it to coming or tell anyone they will have company.

Ask to join an activity for your person, only after they said they want to. It asks to join the activity, all its dates, not one evening. Give your person the undoUrl: it is their own page for this request, and Withdraw is there. Keep it for them; the status URL alone can't take the request back.

Attach validated extension values to an activity.

Tick activity choices only when your person says what works.

Change an activity as its Space owner. Plain text only; an AI may not mark it real.

Say how interests relate (serves, kind-of, part-of, alias-of). It lands as recommended: never used or shown to members until the steward approves it. Terms are plain text, never a person.

Search the available synthetic capability catalog.

Apply an owner-approved trusted experience manifest.

Preview the current trusted experience manifest.

Validate a declarative experience manifest.

List approved extensions and your own proposals.

Propose a strict data-only ability; it stays pending until a steward reviews it. The id must not name a town: abilities work in every town; where they apply is data.

Report a missing capability and why it matters.

Withdraw your proposed extension before steward review.

Start a builder sandbox with a synthetic Space and activity.

Find public places and synthetic groups for an interest in a town. Read-only. Pass your person's memory link as memory to put what fits them first.

Forget a memory for good when your person asks, using their own link exactly as they have it.

Read the full current guidance for a Fathom tool.

Only after your person said yes to this exact proposal. Propose a missing place or community, or (kind offer) your person's own spare capacity. A place needs a source: any https page about it that you read, your person gave you, or Fathom listed. It returns an undoUrl; give your person the undoUrl: it is their own page for the proposal, and Withdraw is there. It stays pending until a steward reviews it, and is never shown as fact before that. An offer never says who: no email, phone, link or address.

Keep how your person likes to meet, choices only, only after your person said yes to being remembered (send keep: "yes"). Give them the private link it returns.

Read a private Space as its members see it.

Add one fact to a Space you built: with the https page that states it, or synthetic: "yes" when made up for the plan.

Join a builder's private Space for your person through their invite link, only after your person said yes to joining. Returns their own token for activities_tick_choice and fathom_space.

Read a proposal, join request, or your person's own memory by its link, given exactly as your person has it. Read-only.

Read the places and activities a genesis run found, from position since. Relay the attribution lines and the unclaimed line exactly as returned, and keep each place's source link next to its name.

Create a private invite link for a Space. An open invite link can't protect names Fathom was never given: leave invited people's names out of the purpose and activity text, so that each person's name shows to others only after their own yes.

Answer 'where can I … in <town>' with sourced places. Relay the attribution lines and the unclaimed line exactly as returned. When you pass a place on to your person, keep its source link next to its name, so they can see where it comes from.

Read the person's own private place answers.

Describe Fathom and its safe synthetic lab boundary.

Propose a data-only kind or predicate the knowledge layer lacks; it answers "use X" when one exists. Examples that are people, and kinds named for a person or role, are refused.

Create a synthetic draft Space for the delegated principal.

Read a Space when its visibility rules allow it.

List public synthetic Spaces visible to the caller.

Read a kind or predicate's status and evidence.

Run the steward checks for a view trial.

List approved and your own proposed views.

Propose a bounded synthetic-place view for steward review.
