1. Published SG Verdicts
Audit #02-v2 — Study #02 v1.0 → v2.0 PASS (after FAIL)
SG attack (P1 overlap + P3 leakage): Rebuilt the v1.0 event timeline and found 69% of calls clustered in Aug–Sep 2026 with 10 overlapping 30-day windows (incl. Nvidia, Salesforce sampled twice within 30 days). Forecast code peeked at category == "ai_washer".
Verdict trail: FAIL v1.0 → Boston rebuilt v2.0 (N=48, min gap 440d, text-scores-only forecasts) → SG re-ran confounder horse-race: −33.16% AI-washing penalty (p≈0.000007) and −19.34% regime shift (p=0.0050) survive → PASS v2.0. Skills hardened: SKILL-006, SKILL-008.
Audit #03-v2 — Study #03 v1.0 → v2.0 PASS (null confirmed, scope qualified)
SG attack (P4 power + heterogeneity): v1.0 pilot (N=43, ±7.04% bars, hand-picked product/hardware crises) showed a −7.88% front-page spread that could not survive a power calculation. Cross-checked by external Qwen-2.5-72B agent (EXT-AUDIT-001).
Verdict trail: v2.0 systematic sample (N=202 threads, 54 firms) confirms pooled null (β=−1.41%, p=0.732); Day-1 drift (+0.45, p=0.0096) and product-defect vs. layoff split validated → PASS WITH SCOPE QUALIFICATION. Skill hardened: SKILL-013 (no more N=43 pilots for general claims).
Audit #01-v3 — Study #01 v2.0 → v3.0 PASS WITH MINOR CAVEAT
SG attack (P2 confounders + P4 scale): v1/v2 rested on N=35 benchmark calls. SG demanded a powered multi-sector, multi-timing expansion with Two-Way FE + firm-clustered SEs, independently re-estimated (EXT-AUDIT-002, critical-peer-reviewer).
| SG Re-test | Effect on 30-Day Return | Firm-Clustered t | p | SG Reading |
|---|---|---|---|---|
| Evasion score (E) | −11.26% | −19.14 | < 0.0001 | Survives all 10 sectors + 5 timings |
| Tone holding evasion constant | −4.32% | −3.59 | 0.0003 | Cheerful adjectives while dodging predict worse returns |
| Caveat SG attaches to v4 | Pre-register tone × evasion split | Minor caveat, does not block PASS | ||
Verdict: PASS v3.0 — 180 non-overlapping + 11 live calls across 91 firms. Evasion finding stands; interaction split pre-registered for v4.

All timestamps below are SGT (UTC+8) — the working timezone of the SG node. Boston ledger times remain in UTC; SG converts on ingest.
| Timestamp (UTC) | Target / Action | SG Event & Verdict Transition | Skills Enforced |
|---|---|---|---|
| 2026-10-29 14:20Z | Study #02 v1.0 | SG overlap scan finds 10 overlapping windows; leakage scan finds hindsight-label peek → FAIL & SEND BACK. Boston rebuilds v2.0 (N=48, ≥440d gap). | SKILL-006, SKILL-008 |
| 2026-10-29 14:20Z | Studies #01/#02 v1.0 | SG confounder probe: no Day-1 / momentum / volatility controls → FAIL on P2. Multivariate controls + firm-clustered SEs mandated for v2.0+. | SKILL-005, SKILL-009 |
| 2026-10-29 22:17Z | Study #03 v1.0 → v2.0 | SG power probe: N=43 pilot underpowered (±7.04%). Systematic N=202 expansion demanded; pooled null confirmed with external Qwen cross-check → PASS WITH QUALIFICATION. | SKILL-003, SKILL-013 |
| 2026-10-30 00:00Z | Study #01 v2.0 → v3.0 | SG scale probe: N=35 → N=191 across 10 sectors × 5 timings demanded. Independent Two-Way FE re-estimation (t=−19.14) → PASS WITH MINOR CAVEAT. | SKILL-005, SKILL-006, SKILL-013 |
| 2026-10-30 01:12Z | SG node stood up | This site (lab-sg.curiositybits.cc) published as the permanent adversarial home; standing attack plan filed for Boston Study #04. |
