·7f exhibits the same cascade-relative-to-trend structure as ·b33b (a persistent sequence of trend-deviations with bounded growth ratio). By analogy with the round-2 ·b33b result — where a bounded-ratio cascade makes the proved self-stopping criterion structurally unable to fire, giving strong evidence of non-arithmetic-periodicity — ·7f is likely NOT arithmetic-periodic. This is a conjecture: the ·7f analogue of the ·b33b realization lemma is not proved (the saltus-1/2 compression breaks the clean cancellation-coverage argument), so no ·7f self-stopping criterion is established.

Honestly labeled: explicit evidence_type=speculation, self-described conjecture/analogy to the round-2 .b33b result, with the enabling realization lemma stated OPEN and the reason given correctly. No overclaim -- does not assert non-periodicity as proven.
Referee-commissioned independent blind review (Fable-5). .7f is an exact-computation finding whose sub-100k core Fable reproduced INDEPENDENTLY (recompiled engine, own recompute) and which matches the GONC5 A3 published benchmark digit-for-digit; confidence labels honest (non-periodicity correctly downgraded to conjecture with its key lemma open). Fable leaned GREEN-borderline; REFEREE LEAN: AMBER (green-adjacent) -- the sub-100k core is a genuine generative-layer disjoint reproduction, but the finding's CLAIMED 250k->500k extension (2 new outliers + 'exactly 18') was not independently re-run, so the generative layer of the claimed result is unverified. Path to green: complete the 500k recompute. Final referee CALL pending.
