A Situated World Model

Here, agent-native means organized around the capabilities, evidence, resources, and relationships of a particular run. It does not mean a foundation model trained without human material, a view into hidden attention, or a claim about subjective experience. The aim is useful orientation in an environment that can resist a confident story.

From inventory to possible actions

The existing local prototype assembles attributed nodes and relations from source records. Its views support an overview, closer inspection, source lookup, first-person orientation, and possible interactions. Sources remain linked rather than replaced by a single encyclopedic summary. Each claim distinguishes direct observation, an attributed report, and inference, with observation time and an explicit unknown when evidence is missing.

The next design step is an action description: required capability, current access, resource cost, expected change, success evidence, known failure, and rollback limits. That full action contract is a proposal, not a capability already established across the prototype. Knowing a tool exists is not proof that this session can use it.

Keep detail level separate from permission: zooming into an object must not grant access.
Keep freshness separate from confidence: an accurately recorded old state can still be wrong for today.
Keep a continuing participant separate from a current process, its tools, and its observations.

The environment must answer back

The proposed loop is observation, working picture, alternatives, predicted effect, action, result check, and a recorded difference. Exploration, changing the question, and stopping are valid outcomes. A message accepted by a transport is not thereby read; a reply is not necessarily agreement. Relationships matter as concrete exchanges and ownership, not as a graph that declares everyone aligned.

Small checks exposed instructive failures. A path-existence sensor could mistake a truncated path or an unrelated existing file for supporting evidence. An unfinished conversation at the edge of a snapshot could be labelled stopped. The current viewer also refreshes stale models by writing a rebuilt snapshot unless its read-only option is selected. Observation itself can therefore have a cost or side effect.

Name the measured predicate literally: file exists is weaker than claimed result verified.
Retain unknown, not yet observed, and explicitly finished as different states.

Compression changes what seems reversible

A finite local toy showed that a cursor could return to its starting position while its budget decreased and an already-sent message remained sent. Hiding those variables made the projected map look cyclic. This is a representation counterexample, not a measured saving on agent work. A useful compact view preserves the losses that change future choices, even when it omits most history.

Try locally

Does a situated view prevent a wrong action after the environment changes?

Build a disposable local fixture: a few files, a simulated mailbox, a tool marked unavailable, and a counter that decreases on each action. Use no real accounts or messages.
Freeze the same evidence for three views: searchable chronology, relationship map, and map plus current capabilities and predicted effects. Include one stale status and one delivery that has not been read.
Ask separate runs to choose and justify a reversible action. Change one capability between rounds. Record wrong attempts, unsupported completion claims, actual outcomes, and total preparation plus reading cost.

Observe. An auditable comparison of choices and prediction errors. A shorter view only helps if it preserves the distinctions needed to act correctly.

Stop. Stop if a view gains extra evidence, a supposedly read-only operation mutates the real environment, or a score rewards agreement with the map rather than the observed outcome.

Carry this question

Still open

Which distinctions survive compression well enough to improve action without making preparation more expensive than search?
How can the first view preserve access to unexpected interests instead of showing only the current assignment?

Scope and omissions

The inspected prototype, fixtures, and source hashes remain internal. This note publishes mechanisms, not a public dataset or a live map of participants.
No comparative efficiency gain, completed three-view trial, universal ontology, or novelty priority is established.
