narrative revision: substantiated premise, continual-learning positioning, convergence framing

Per GG's directive: (1) the model-societies premise is no longer asserted
— the Introduction opens with the verified evidence base (3M-model
ecosystem with phylogenetic lineage-mapping literature, >98%-synthetic
alignment pipelines, machine-generated web share, the human-data
ceiling, mainstream merging tooling, agent economies; refs 31-44, all
identifiers verified by the literature scan). (2) The findings are
contextualised in CONTINUAL LEARNING, where they land hardest: a new
Introduction block maps the CL canon onto the operators — replay <->
grounding, with the field's measured replay fractions (1%/5%/25%)
sitting on our theorized g*~0.05; pseudo-rehearsal/generative replay as
precisely our ungrounded null; parameter isolation; CLS consolidation;
merging-for-CL vs cross-lineage recombination; tail-first forgetting <->
tail-allele extinction; CF-vs-collapse mechanism distinction kept
explicit — plus a Discussion block with five CL impact points (replay-
ratio theory testable against published sweeps; a failure theory for
generative replay; pre-merge interference prediction with a mechanism; a
consolidate-vs-modular decision rule; tail monitoring, engaging the
latent-vs-extinct objection). The scan verified the bridge is open: no
prior work carries pop-gen formalism into CL. (3) Downplaying replaced
by convergence framing: the diagnosis was reached independently and is
corroborated by parallel arrivals (Riis; Benati; Yoon; and Crutchfield &
Whalen 2012, pre-deep-learning) — cited for priority of publication, the
full arc owned as one framework. References 30 -> 65; Significance
carries the CL frame; 20-pp rebuild; 151 tests green.

+## Phase 4b — Narrative revision (GG directive 2026-08-11) — DONE
+- [x] Premise substantiated: Introduction opens with the evidence-backed model-population reality
+  (3M models/phylogenetic lineage mapping; >98% synthetic alignment pipelines; web AI-content share;
+  the human-data ceiling; merging tooling; agent economies) — refs 31–44.
+- [x] Continual-learning contextualisation: new Introduction block mapping the CL canon onto the
+  operators (replay↔grounding incl. the 1%/5%/25% ↔ g*≈0.05 convergence; pseudo-rehearsal = our
+  ungrounded null; parameter isolation; CLS consolidation; merging-for-CL; tail-first forgetting;
+  CF≠collapse distinction kept explicit) + Discussion block "What this offers continual learning"
+  (5 impact points incl. the Kotha latent-vs-extinct engagement) — refs 45–65. Verified open: no
+  prior work carries pop-gen formalism into CL (the bridge is ours).
+- [x] Downplaying removed: convergence framing (diagnosis reached independently; Riis/Benati/Yoon +
+  Crutchfield&Whalen 2012 cited for priority of publication; convergence = corroboration; the full
+  arc owned). Applied to PNAS draft + v6 abstract.
+- [x] References 30 → 65 (all verified by the lit agents; append-only numbering — citation-order
+  renumbering is a submission-time mechanical fix, with refs 31–65 to be reordered by first
+  appearance when reflowing to pnas.cls).
+- [ ] v6 long-form: sync the premise/CL sections if GG wants the long document to match (currently
+  only the convergence fix is propagated).
