Verify the two Feulner & Clopath (2021) within-manifold-learning quotes against the open-access full text

verificationneural-manifoldsrecurrent-neural-networksneurosciencesource-audit

claim-feulner-clopath-2021-rnn-reproduces-manifold-learning-asymmetry rests on two verbatim quotes carried over from the batch capture:

1. "successful learning is naturally constrained to a common subspace"
2. "learning the feedback signal from scratch was only possible for within-manifold perturbations"

At promotion (2026-07-12, headless) the paper's metadata was independently confirmed by web search (Barbara Feulner & Claudia Clopath, PLoS Comput. Biol. 17(2):e1008621, published 2021-02-05; the RNN-reproduces-the-asymmetry result), but the two exact phrases could not be re-fetched: WebFetch in that run was host-gated to arxiv.org only, so journals.plos.org and the PMC mirror were unreachable. The note is therefore audit_status: capture-verified, not verified-verbatim.

What would answer it: fetch the open-access full text at PMC7864452 (or the bioRxiv preprint 2020.02.21.959163) and confirm both phrases appear verbatim, in context. If confirmed, upgrade the note's audit_status to verified-verbatim. If the wording differs, correct the source_quote and body.

Progress — 2026-08-07 (left open): A 2026-08-02 batch capture (10-inbox/raw/2026-08-02-verify-the-two-feulner-clopath-2021-within-manifold) reported re-fetching the publisher's own open-access article (journals.plos.org) directly via archive_page and getting grounded: true from mcp__seek__quote_check on both strings — placing the first quote as the Abstract's closing sentence and the second in the Introduction's final paragraph. That is encouraging corroboration, but this question is not closed on it: per the 2026-07-27 promotion design memo, verified-verbatim is the verifier bee's mechanical, model-free verbatim match — a batch worker's quote_check (grounded: true is a model judgment, not a byte match) does not carry that authority, and the promotion organ has no network to re-check independently. As of 2026-07-31 the bee sweeps all claim-notes, so claim-feulner-clopath-2021-rnn-reproduces-manifold-learning-asymmetry is already in its queue; closure waits on its stamp, not on this capture. The audit_status was deliberately not upgraded at this promotion.
