A world lived from within a complete history

The world does not need an outside projector

A complete history and a lived temporal world answer different questions. The history contains a note's emission, propagation, reception, retention and interpretation. The listener never receives that entire description. Placing two notes on a spacetime diagram does not explain hearing one as following the other. The task is to follow the relevant physical relation into the organization that actually uses it.

Shadow Theory gives this task a definite architecture. Source and readout name complementary structural and presentation roles within one reality. Readout includes instruments, bodies and records; it is not an image delivered to a witness outside the world. The source–readout mathematics asks which relations descend to a representation, what distinctions a sufficient completion must preserve, and when projected dynamics close. The philosophical account distinguishes the unknown Ground and unsplit unity from every working source model. The enacted-experience account identifies complete qualifying organization with the experience, without adding a recipient beyond it. The references identify the canonical mathematics [24–26,28,29] and experiential sources [21,36,37].

A block interpretation supplies a temporal setting for this architecture. Events occupy causal and temporal locations without a universal present advancing through the world. An organization within that history still changes, learns and acts. Its stages genuinely differ in what they receive, retain and can do. Those differences belong to the history. Relativity supplies causal restrictions and no invariant inertial simultaneity convention; the further interpretation of all actual events as equally real requires an ontological argument [17,43,44].

The integration works in both directions. Relativistic history makes physical realization demanding: a local readout needs communication routes, clocks, preparation, storage and a deadline. Shadow Theory identifies the precise distinction that must reach a participant, the completion needed to support a task, and the constitutive account under which its actual use is experienced. Its target-relative completion theory also gives explanatory economy an exact meaning: an extra actuality selector supplies no needed distinction when it preserves the declared predictions, records and complete qualifying enactments.

A retained predecessor, live contribution and anticipated continuation can participate together without representing their sources as simultaneous. Interpretation can begin before a sequence ends. This is explanatory integration and a physical realization programme. Neither the block interpretation nor the unknown Ground receives experimental confirmation merely because the two descriptions fit together.

The physical argument goes beyond saying that memory is limited. Two independently prepared source features pass through a solved delivery and memory programme. Exact optimization identifies the attainable accuracy for a directed relation. Binding interventions preserve stored information while changing the relation actually executed. A separate coherent-completion benchmark asks a stronger quantum question under different preparations. These supply quantitative constraints on how a source becomes usable organization.

Two distinctions remain decisive. Global co-reality is different from causal access or temporal interpretation. A reciprocal-pair theorem has strong geometric consequences, but an actuality interpretation requires its own witness. Local information loss is different from loss in the source-to-entire-history map. A complete physical history may itself be a sufficient working source. The following chapters preserve those distinctions while developing the positive construction.

The full argument connects whole-field constitution, experienced temporal passage and constituted agency. Each connection concerns a specified explanatory role rather than an exchange of names.
