+# Whole-future memory companion
+
+Research candidate, not yet independently accepted or compiler verified. Based on
+the accepted finite-block trajectory recovery at PR #990, `a958bc54`.
+
+## Exact object and entropy convention
+
+Let the finite initial sample space be Ω = V × H, with arbitrary normalized law μ,
+and let φ permute Ω. Define F(s)(j) = πV φ^(j+1)(s), for every natural j. The
+codomain FutureTrace is **the image of F**, a finite set of entire sequences. It
+is finite because F has finite domain. It can have fewer elements than Ω.
+
+At time t the whole-future random variable is Y_t(q) = F(φ^t(q)). Its j-th decoded
+coordinate is exactly X_(t+j+1)(q), not a finite-prefix approximation. Two codes
+are equal exactly when their decoded sequences agree at every future time.
+Every finite future block is a deterministic truncation of this same variable.
+
+The entropy convention here is ordinary discrete Shannon entropy of Y_t on its
+finite image, and similarly for its finite joint laws with X_<t and X_t. This is
+the literal entire-future variable for this finite deterministic realization.
+No infinite-product measure, sigma-algebra conditional entropy, limit theorem,
+or identification with a separate measure-theoretic convention is formalized.
+
+## Written proof
+
+Y_t is a deterministic function of (X_t,H_t), while the time-t joint law is the
+pushforward of μ along q ↦ (X_<t(q),φ^t(q)). Therefore the existing finite Shannon
+data-processing theorem applies to the actual entire-future variable:
+
+Iμ(X_<t;Y_t | X_t) ≤ Iμ(X_<t;H_t | X_t) ≤ log₂|H|.
+
+The bound holds for every natural t. The range of these conditional information
+values is nonempty and uniformly bounded above. Hence its genuine real supremum
+I*whole satisfies I*whole ≤ log₂|H|, and exponentiation gives 2^I*whole ≤ |H|.
+No replacement of a supremum by a finite maximum is made.
+
+This argument needs neither a period bound nor a claimed N−1 distinguishing
+horizon. It does not prove that a chosen finite prefix already determines the
+entire future. It does not derive a physical preparation, measurement or retained
+record, hidden-state opacity, or information accumulation without hidden reuse.
+
+## Relation to the manuscripts
+
+Main §3.4's C3 proof explicitly treats X_>t as a function of (X_t,H_t), but does
+not specify an infinite-product entropy convention. Under the finite-image
+discrete convention stated above, the companion matches that whole-future
+argument and the supremum over natural times. Any broader stochastic-process or
+measure-theoretic reading remains a separate dependency, not a silent promotion.
+No manuscript, coverage grade or prior accepted source is changed here.
+
+## Verification path
+
+The new module is imported by OIBridge's normal CI build and has a kernel-only
+research entry before the preserved final KTOKEN census family. Eight endpoint
+axiom reports are printed. No local Lean/Mathlib build or full suite is run under
+AGENTS A.40. The bounded independent controls use complete permutation-period
+words to encode entire traces in finite examples, with nonuniform/correlated
+initial laws, a short-prefix countercontrol, and sharp cyclic-register examples.
+These examples are controls, not universal proof certificates.
