+## Decision
+
+Fold this into Research Stack as a serious external anchor for dimension-independent convex covering, geometry/probability translation, bounded-complexity generator decompositions, and high-dimensional admissible envelopes.
+
+Do not fold it in as proof of any internal Research Stack theory by itself.
+
+Safe project sentence:
+
+> Talagrand convexity is an external mathematical anchor for fixed-complexity high-dimensional envelopes: scattered high-dimensional mass can admit bounded-complexity convex structure independent of ambient dimension.
+
+## Source theorem boundary
+
+The arXiv abstract says the paper proves that every centered 1-subgaussian random vector in real n-dimensional space decomposes as a sum of a universal number of standard Gaussian vectors. The authors state that this resolves Talagrand's convexity problem after Song's reduction and implies a combinatorial analogue.
+
+Research Stack status:
+
+```text
+EXTERNAL_MATH_ANCHOR
+not
+PROVED_BY_RESEARCH_STACK
+```
+
+Any Lean dependency must be modeled as an explicit external oracle until independently formalized or stabilized by the mathematical community.
+
+## Project mapping
+
+| External concept | Research Stack mapping |
+| --- | --- |
+| High-dimensional point cloud | manifold points / semantic mass field / behavioral vector population |
+| Convex construction | admissible envelope / projection hull / boundary gate |
+| Dimension-independent fixed complexity | compact generator budget / primitive-count ceiling |
+| Centered 1-subgaussian vector | bounded residual-noise packet |
+| Universal Gaussian decomposition | finite generator decomposition / reconstruction basis |
+| Geometry-to-probability reduction | cross-domain adapter / stochastic witness map |
+| Combinatorial analogue | finite packet / discrete cover interpretation |
+
+## Compression interpretation
+
+```text
+apparent dimension != generator eigenmass
+```
+
+The useful claim is not that arbitrary high-dimensional data compresses for free. The useful claim is that some high-dimensional bounded stochastic/geometric structures may admit a small lawful envelope whose complexity does not scale directly with ambient dimension.
+
+That is directly aligned with the Research Stack compactification rule:
+
+```text
+many projected axes
+  -> fewer lawful generators
+  -> residual handled by witnesses/scars
+```
+
+## AI-assistance boundary
+
+The press account reports AI as a navigation aid around a proof bottleneck, not as the final certifier. The durable Research Stack lesson is:
+
+```text
+Builder may probe.
+Judge must verify.
+Warden controls promotion.
+```
+
+## Future fold-in targets
+
+1. `DimensionIndependentCover.md` — admissible covers whose complexity does not scale directly with ambient dimension.
+2. `ProbabilityGeometryAdapter.md` — reductions between geometric envelopes and stochastic packet decompositions.
+3. `SubgaussianResidualPacket.lean` — future Lean scaffold for bounded residual packets, initially oracle-backed.
+4. `ConvexEnvelopeAnchor.md` — concept note for convex hull/envelope structure as a boundary gate.
+
+## Claim ladder
+
+| Use | Status |
+| --- | --- |
+| External citation anchor | Accepted into docs |
+| Analogy for compact generator budget | Accepted with caveat |
+| Direct theorem dependency | Oracle only until formalized or externally stabilized |
+| Internal proof of Research Stack manifold theory | Rejected |
+| AI-proof evidence | Rejected; AI-assisted navigation only |
+
+## Keeper
+
+Talagrand convexity gives Research Stack a serious external anchor for the idea that high-dimensional scatter can still have a bounded-complexity admissible envelope.
