Definition
The Relativistic Transactional Interpretation is Kastner's development of the transactional account of quantum mechanics. It treats offers and confirmations as physically real possibilities outside ordinary spacetime; a completed transaction actualizes one outcome and establishes spacetime events. The books adopt it as an account of becoming while retaining its minority, contested status and distinguishing its physical interpretation from mathematical probability structure.
Explanation
AB chooses RTI for its account of relational actualization and emergent spacetime, but calls the choice a wager. Its notes distinguish interpreting the amplitude–conjugate pairing from deriving the Born rule merely from two participants. Convergence with Simondon is suggestive, not independent proof. PB likewise acknowledges philosophical attraction and labels its categorical treatment an interpretive graft: the mathematics neither selects an outcome nor derives relativistic interaction or spacetime emergence.
RB1 distinguishes Kastner's development from earlier TI and records the local PTI designation. Offers and confirmations are not energy signals travelling along a timeline before completion. Its discussion preserves empirical equivalence at the level of predicted probabilities while treating absorption criteria and coherent storage as research questions, not established experimental discrimination.
RB2 uses RTI to illuminate the interface of actualization and growing spacetime record; its emergent-gravity application is explicitly speculative and unnecessary to Law 8. RB3 uses RTI as a physical analogue for constrained indeterminacy, with compatible absorbers and conservation conditions limiting actualization. It says the philosophical grammar does not depend on RTI being correct, although its physical formulation would require revision under another interpretation.
Scope and attribution
All five books own treatments. RTI and PTI are local names for Kastner's development; unqualified TI retains its separately identified historical scope. Mathematical models, empirical illustrations and philosophical analogies are not proof of RTI.
AB — The Actual Book
AB adopts RTI as a relational account of one outcome and emergent spacetime. Its notes retain Cramer's ancestry and explain that the conjugate pairing is interpreted, not derived from mere two-sidedness. The Simondon convergence is acknowledged as partly selected for, not independent confirmation.

PB — The Possible Book
PB names its attraction to RTI and admits that the resemblance to Simondon is not evidence. Its Tractatus uses the handshake, while the categorical module explicitly supplies probability structure without outcome selection, relativistic dynamics or proof of spacetime emergence.

RB1 — The Real Book, Volume I: The Possible Is Real
RB1 explains RTI/PTI as Kastner's development of TI, with pre-spacetime offers and confirmations rather than travelling energy signals. It records empirical equivalence in predicted probabilities, objections concerning quantitative absorption criteria and the absence of an established discriminator. The coherent-storage application is explicitly an authorial inference.

RB2 — The Real Book, Volume II: Becoming Is Being
RB2 uses transactions to articulate the active present and the growing spacetime record. Its emergent-gravity discussion is illustrative, contested and empirically unsettled; neither Law 8 nor the broader argument depends on its truth.

RB3 — The Real Book, Volume III: Murmurations
RB3 enlists RTI as a physical analogue, not proof of Simondon or an established interpretation. Its transaction account combines chance with eligible absorbers and conservation constraints. The philosophical grammar is separable from this physical implementation, which would need regrounding under a no-collapse interpretation.

Background used in the editorial explanation
Domain-specific mechanisms and wider analogies remain distinguished. Original definitions retain their scope; local cross-references do not rewrite them. Named theories and mechanisms are distinguished from neighboring background, homonyms and the author’s own synthesis. Reproduced AI passages retain their separate voice.
