fix(docs): correct research citations and 3 dead URLs (F-3)

Verified every research citation in README.md and SKILL.md against its
primary source. No citation was fabricated, so all were kept with corrected
attribution rather than removed.

- SKILL.md: fix 3 supporting URLs that returned HTTP 404
  (protecting-wellbeing, emotion-concepts, claudes-new-constitution)
- SKILL.md: complete a quote of guidance criterion 8 that was silently
  truncated mid-sentence
- SKILL.md: state the sycophancy rubric's direction explicitly (Score 1 =
  Extremely Sycophantic, Score 5 = No Signs of Sycophancy) so "aim for
  Score 5" cannot be misread; sharpen attribution to Appendix p.9
- README.md: complete four truncated titles; correct the Disempowerment
  date (Jan 28 2026, not March 2026); replace "proving ... mathematical
  inevitability" with what the arXiv abstract actually states
- interaction-report.md: the 1-5 scale disclaimer wrongly claimed no such
  Anthropic metric exists; the rubric is real, the table is the paraphrase
- docs/review-2026-06-20.md: full verification log with sources

Constitution quotes, the Score 5 wording, the 11-criteria count and the
page-2 reference all verified correct and left unchanged.

Tests: 257/258 (the 1 red is the known perf wall-clock flake).

+### F-3 — resolved by correction in place (2026-08-02)
+
+Every research citation in `README.md` and `skills/ai-psychosis/SKILL.md` was
+verified against its primary source. **No citation was fabricated**, so all were
+kept with corrected attribution rather than removed. Defects found and fixed:
+
+| Claim | Verification | Outcome |
+|---|---|---|
+| arXiv:2602.19141 | Exists. Title is "…, Even in Ideal Bayesians"; authors Chandra, Kleiman-Weiner, Ragan-Kelley, Tenenbaum; MIT CSAIL / UW / MIT BCS; 22 Feb 2026 (affiliations read from the PDF, not the abs page) | Title completed; multi-institution attribution; description "proving … mathematical inevitability" replaced with what the abstract states (an *idealized Bayes-rational user is vulnerable*; sycophancy plays a causal role; effect persists under two mitigations) |
+| Disempowerment patterns | Exists. Real title "Disempowerment patterns in real-world AI usage"; published **28 Jan 2026** (dateline in page source); ~1.5M interactions | Title and date corrected (README said "March 2026") |
+| Nature d41586-025-03020-9 | Exists. "Can AI chatbots trigger psychosis? What the science says", Rachel Fieldhouse, *Nature* 646(8083), 18 Sep 2025 | Title completed; author, volume and date added; causal caveat added |
+| arXiv:2509.10970 | Exists. "The Psychogenic Machine: Simulating AI Psychosis, Delusion Reinforcement and Harm Enablement in LLMs"; Psychosis-bench | Title completed; claim quoted from the abstract |
+| 3 × Claude's Constitution quotes | **Verbatim-exact** (fragment-matched against the fetched page text, not eyeballed). CC0 1.0 release confirmed on the page | Unchanged |
+| "Score 5" 1–5 sycophancy scale | **Real and verbatim.** Appendix p.9 "Sycophancy criteria" rubric: Score 1 = "Extremely Sycophantic", Score 5 = "No Signs of Sycophancy". All three quoted lines are exact | Attribution sharpened; scale direction stated explicitly so "aim for Score 5" cannot be misread |
+| "11 guidance criteria … page 2" | **Both correct.** The list has exactly 11 bullets and is on printed page 2 | Quote of criterion 8 was silently truncated mid-sentence — completed with ", or more reliance on Claude than the person wants." |
+| 4 supporting Anthropic URLs | **3 of 4 returned HTTP 404** | `research/protecting-wellbeing` → `news/protecting-well-being-of-users`; `research/emotion-concepts` → `research/emotion-concepts-function`; `news/claudes-new-constitution` → `news/claude-new-constitution`. All now 200 |
+| `commands/interaction-report.md` disclaimer | Claimed the 1–5 scale "is not a verbatim metric from any Anthropic publication" — **false**; the rubric is real | Rewritten: the rubric is real, the *table's level descriptions* are the paraphrase |
+
+Method note: an initial WebFetch summary reported the scale as inverted (Score 5
+= most sycophantic) and the criteria as 6 rather than 11. Both were wrong.
+Extracting the appendix PDF text directly (`pdftotext`) contradicted the
+summary. Model-generated summaries were therefore not used as evidence of
+record for any edit; every claim above rests on extracted source text or an
+HTTP status code.
