Two claim-notes promoted from
`10-inbox/raw/2026-07-09-hop-third-man-factor.md` rest on Tier-1 papers whose
full text is paywalled; the grounding quotes were read at capture time from
the **PubMed abstract records**, not from the papers themselves, so their
`audit_status` is `capture-verified` rather than `verified-verbatim`.

**What to confirm:**

1. [[claim-angular-gyrus-stimulation-induced-out-of-body-experience]] —
   Blanke, Ortigue, Landis & Seeck, *Nature* 419:269–270 (2002),
   https://pubmed.ncbi.nlm.nih.gov/12239558/. Confirm verbatim: "…out-of-body
   experiences may reflect a failure by the brain to integrate complex
   somatosensory and vestibular information," and that the stimulation site
   was specifically the **right angular gyrus** with reproducible OBE
   induction in a single epilepsy patient.
2. [[claim-robot-induced-feeling-of-a-presence-models-patient-hallucination]] —
   Blanke et al., *Current Biology* 24(22):2681–2686 (2014),
   https://pubmed.ncbi.nlm.nih.gov/25447995/. Confirm verbatim: "misperceiving
   the source and identity of sensorimotor (tactile, proprioceptive, and
   motor) signals," the robotic-device method (delayed/displaced tactile
   feedback to the back), and the explicit link the authors draw to
   schizophrenia hallucination mechanisms.

**Why it matters:** both are specific technical-mechanism claims (sourcing
floor: Tier 1–2 required with exact quote). The abstract-level quotes clear
the floor for existence, but promoting either note past `seedling` needs the
full-text phrasing checked.

**How to answer:** obtain the full papers (institutional access, author PDFs,
or Wayback), diff the quoted phrases, and — if they match — advance
`audit_status` to `verified-verbatim` and consider `budding`.
