Multi-Contour Semantics ​

Within the current architectural core of Realith, it is already defined that contour is a strong environmental boundary.

The key line at present is this:

Cross-contour significance in Realith must not be read as automatic same-object semantics. If an object acquires a canonically significant form in another contour, this must occur through an explicit contour-relative artifact in the target contour, with a typed relation to the source object and with a separate recognition basis in that target contour.

Boundary rules of this hypothesis ​

The following rules are already retained as a mandatory boundary line of the current hypothesis:

• Contour remains a strong environmental boundary, not a visibility flag;
• canonical recognition is always contour-relative;
• one and the same object must not silently be treated as the same thing across several contours at once;
• cross-contour significance is admissible only through an explicit contour-relative artifact in the target contour;
• such an artifact must have a typed relation to the source object;
• the target artifact requires its own recognition basis in the target contour;
• visibility change, publication, published outcome, gateway, bridge, external compatible view, and operator service do not create identity by themselves;
• projection, copy, derived representation, derived object, and the same object are not identical by default.

This hypothesis:

• preserves contour as a strong architectural boundary;
• is compatible with the current stack object / relation / transition / recognition basis / canonical recognition / canonical current state;
• does not make visibility, publication, compatibility, or the operator layer a hidden source of identity;
• does not require a premature same-object doctrine at the level of a finished specification.

What remains deferred ​

After this line is accepted, the following remain deferred:

• the final vocabulary split between projection, derived representation, and derived object;
• the precise admissibility rules for the cross-contour step;
• target-side structure and lifecycle mechanics, including own structure, own active version, and own transition line;
• the publication / proof profile of such an artifact;
• implementation, operator, and conformance mechanics.

If the question is not retained explicitly, false expectations arise:

• as if any object were automatically transferable between contours;
• as if contour were just visibility rather than a strong environmental boundary;
• as if projection, copy, and the same object were the same thing.

What this does not mean ​

Even after adopting this hypothesis, one still cannot assert that:

• the final vocabulary is already fixed;
• the exact admissibility rules are already fixed;
• same-object doctrine across contours is already completed;
• target-side lifecycle mechanics are already fixed;
• the final proof/publication mechanics for the cross-contour artifact are already defined;
• implementation, operator, and conformance mechanics are already defined definitively.

In Realith, cross-contour significance must be read not as automatic same-object semantics, but as contour-relative artifact semantics. Vocabulary split, admissibility rules, target-side lifecycle, publication/proof profile, and implementation/conformance mechanics remain deferred.
