# URL-addressable State
|
||
|
|
|
||
|
|
Context: readers need to share, bookmark and revisit a resource or selected view.
|
||
|
|
Problem: an address change can conceal state that only exists in the current tab.
|
||
|
|
Addressability competes with private/transient state and URL/schema stability.
|
||
|
|
|
||
|
|
Proposed solution: encode the public, stable resource identity and relevant view
|
||
|
|
selection in path/query parameters. Define parameter validation, defaults and route
|
||
|
|
resolution so direct entry and reload reconstruct that selection under current
|
||
|
|
authorization. A URL identifies a view, not necessarily immutable bytes or guaranteed
|
||
|
|
future availability. Use an explicit version if a stable historical snapshot matters.
|
||
|
|
|
||
|
|
Do not place secrets, private draft content, focus or every transient interaction
|
||
|
|
in the address. An identifier confers no authorization. Server-visible query/path
|
||
|
|
state and fragment-only state have different resolution contracts. If history is
|
||
|
|
enhanced, back/forward, cache misses and direct loads must resolve coherently;
|
||
|
|
pushState success alone is insufficient.
|
||
|
|
|
||
|
|
Consequences: views become independently reachable, but parameter compatibility,
|
||
|
|
invalid/deleted resources and full-versus-fragment cache behavior need contracts.
|
||
|
|
Alternatives: ephemeral in-tab selection when sharing is unnecessary; authenticated
|
||
|
|
saved-view identifiers when the selection is too large or private for the URL.
|
||
|
|
|
||
|
|
Evidence: [navigation review](../reviews/NavigationRenderingEvidence.md) N01/N02/N06
|
||
|
|
locates documentation mechanisms, not verified deployments of this whole proposal.
|
||
|
|
Full-pattern known uses and recurrence remain unknown. Refines the existing URL as
|
||
|
|
Application State seed; no canonical identity or admitted relations.
|
||
|
|
|
||
|
|
Proposed connection: [Progressive Enhancement](ProgressiveEnhancement.md) can preserve
|
||
|
|
native navigation while adding faster transitions; it is optional, not required by
|
||
|
|
addressability. [VC-03](../walkthroughs/VC03-ContentPublication.md) is a synthetic trace.
