The claim
The nucleating-argument line cited the pragmatic-transport line only as data: its theses CLAIM-017, CLAIM-115 and CLAIM-133 as instances of drift. It did not use the transport line’s results. Read as transport, an argument restated across sessions by collaborators who keep no memory is a chain of retellings, CASE-015’s telephone game. Each session reconstructs the argument from what reaches it, and passes on its reconstruction.
Three transport results then apply:
- Convergence is not preservation (CLAIM-081). A chain can settle on a stable form while forgetting where it started. A thesis that keeps coming back in some form is not thereby the same thesis.
- Drift has a direction. Serial transmission is “filtered by the transmitters’ inductive biases” (CLAIM-090), and Bayesian learners who sample from the posterior converge to their shared prior (THEORY-155). Read across, unanchored restatements should drift toward the collaborators’ stock framings. That is a prediction CLAIM-180 does not make: it treats drift as retrieval failure outside a critical distance, which by itself has no direction.
- Local errors propagate by the chain’s dynamics (CLAIM-056). The same small restatement error can be damped, accumulate or be amplified. That is the transport form of what CLAIM-186’s note takes from generalized stability theory.
A code changes the chain. CLAIM-002 says identity across retellings is a family of relations, artifact, continuity of transmission and similarity of function, and that “descent is not similarity”. Re-derivation is identity by similarity alone, which is all a memoryless collaborator has (CLAIM-180). A code supplies continuity of transmission: later entries reach the claim by descent, by its code, not by resemblance. That is why storage does not anchor and addressability does (CLAIM-182).
What it does not say
- It does not say the chain is memoryless. The transcripts persist (CLAIM-182), and the owner carries memory across sessions and reintroduced the relativity analogy (CLAIM-177). The convergence theorems assume transmitters with no access to the source, and CLAIM-066 limits Griffiths and Kalish’s result to learners that sample from the posterior. The channel back to the source is weak, not absent.
- It does not say developing an argument aims at preservation. It does not; see the counter, CLAIM-189.
- The direction prediction is untested. CLAIM-177’s evidence was coded by readers from the same assistant family (CLAIM-085).
Note of 2026-10-12: a measured case for the direction of drift
CASE-068, filed in PR #121, is now a ground of this claim. In two serial-reproduction studies of risk messages, the transmitters’ measured risk perception predicts the direction in which the evaluative signal changes, and re-exposure to the balanced source did not undo the drift. That is a measured instance of drift toward the transmitters’ bias, and of a return to the source failing to pull a chain back. Its limit is CLAIM-234’s: the record’s chain evidence covers evaluative stance, not footing, and not the restatement of an argument. The chains are of human retellers, not memoryless sessions, and in one study the prior was measured after the experiment.
Note of 2026-10-12: the regimes this claim leans on
The third point leans on CLAIM-056’s regimes. CLAIM-056 carries an Active objection, CLAIM-208, which says a sensitivity needs many retellings of each of several inputs at every generation, “where a chain gives one”. The record conceded it for CLAIM-059 and CLAIM-078 and left CLAIM-056’s condition unchanged. CLAIM-059 version 2 now asks for “several independent retellers per generation”, in a metric other than total variation. A sequence of memoryless sessions gives one restatement per generation, so testing the third point in this claim’s own setting would need that design.
Note of 2026-10-13: premises re-pointed to their general forms
This claim needed only the distinction between retention and drift, and the error recursion with its regimes, not the account of translation it was
filed under. Under ADR-040 that content is filed separately as CLAIM-270 and CLAIM-267, in
the formal-apparatus line, and this claim’s rests_on now names
CLAIM-270 and CLAIM-267 in place of CLAIM-081 and CLAIM-056. The body’s citations of CLAIM-081 and CLAIM-056 stand: they
are where the record first argued the point. The change is that setting
pragmatic-transport aside no longer takes this premise with it.
