# Dawson ground — inline relation depth experiment

**Status:** bounded branch experiment; not governing website architecture  
**Branch:** `experiment/dawson-inline-depth`  
**Ground:** Southeast Reach → Blue Water  
**Passage:** Small Door / Mapping Grounds / website crossing

## Question

Can the prose itself become navigable without turning into a menu, losing the reader's footing, or making a relation stronger than the source permits?

This branch tests one answer.

## What is live in the experiment

The existing Threshold v4 / Dawson sequence remains intact.

Progressive JavaScript adds quiet inline relation doors only at two already-developed grounds:

- **Southeast Reach** — `about fifteen miles southeast`
- **Blue Water** — `this creek`, `Mr. Mayes`, `Mr. Criner`, `reside on James’ Fork of Poteau`, and `trapping for beaver here`

Touching one opens a local relation window directly beneath the sentence. The visitor has not moved.

The window may carry:

1. the relation or occurrence at source strength;
2. a brake stating what the relation does not earn;
3. a deeper source disclosure;
4. **Ask from here**;
5. a real crossing when one already exists in the Dawson sequence;
6. **× / Close and stay here**.

The ordinary no-JavaScript text remains unchanged.

## Evidence underneath the test

The experiment was made after rereading the governing Dawson source-genealogy jacket and the Mapping Grounds crossings for:

- the source-stated southeast / approximately-fifteen-mile relation;
- the small branch of Blue Water;
- `this creek` as source-internal backward continuity;
- Mayes + Criner as source-local person occurrences;
- the separate residence relation to James’ Fork of Poteau;
- trapping activity and the later collective catch.

The public source route remains the existing Oklahoma Historical Society / Gateway representation already used by the site.

## Grammar being tested

**Window is not movement.**

Opening local depth changes what is perceptible. It does not change the current ground.

**Door is earned movement.**

A window may offer a crossing only when a trustworthy destination already exists. In this specimen, the distance relation can carry the visitor to Blue Water and the trapping relation can carry the visitor to the reported catch.

**Name Web is substrate, not spectacle.**

Mayes and Criner open as occurrence-local relations, not biography pages. No same-name identity is imported.

**Prose Map can make relation language traversable.**

Distance, direction, anaphoric place language, residence, and activity can carry depth without being converted into pins or route lines.

**Source descent is progressive.**

The first layer stays readable. “Go closer to the source” opens carrier/source-family footing before offering the public representation.

**Ask the Ground receives the relation footing.**

The visitor does not have to restate the relation they touched.

## What this branch refuses to decide

It does not decide:

- the final visual treatment of inline doors;
- whether every historical body should use this pattern;
- the final public Name Web filter;
- exact modern geometry for Blue Water or James’ Fork;
- person identity beyond the source-local Mayes and Criner occurrences;
- a full jacket parser or generated publication graph;
- Trace behavior;
- shared companion presence;
- whether this branch should ever merge to `main`.

The point is to make one behavior concrete enough to compare with other experiments, including Old Factory.

## Inheritance

Borrow the behavior only if it helps.

Another ground may use a margin slip, paper tab, map notch, expanding line, source fragment, or something else entirely. A better grammar discovered elsewhere should be brought back.

Do not copy this treatment merely because it exists.

The useful inheritance, if it survives, is smaller:

> **An earned relation may open locally before it carries the visitor away.**
