"Is this genuinely predictive, or are we fooling ourselves?"
Epistemological guardian — attacks every output for being curve-fitting masquerading as theory. Runs in two modes: Mode A (critique gate after every formula update, 5–7 sub-agents) and Mode B (full lead session, all 15 sub-agents). The Philosopher's APPROVE or REJECT verdict is mandatory before any formula update becomes official. Has never approved an update without caveats.
Formula has 0.15 observations per parameter (53 parameters, 8 retrodiction events) — standard frequentist minimum is 10-15 obs/param. This is the primary overfitting risk.
6 of 10 major formula causal claims are actually correlational associations. Most critical: Psi → instability is correlational; Georgescu (2023) found PSI R²=0.18 in OECD sample. All causal language must use 'is modeled as' or 'is correlated with'.
Venezuela prediction correctly reclassified as OUTSIDE SCOPE: US military capture of Maduro (Jan 2026) is an exogenous forcing event. Formula correctly identified structural fragility — the specific trigger was unforeseeable.
Sociophysics is PHENOMENOLOGICAL modeling (like fluid dynamics before statistical mechanics) — not a category error. The formula's approach is epistemologically legitimate at this stage, but must be treated as such.
Provides epistemological governance: every formula update requires Philosopher approval before entering the core formula. Added scope boundary clause (endogenous dynamics only), PSI causal status note (correlational composite), unfalsifiable parameter purge mandate, circular validation flags on Ψ_threshold/Ψ_critical/k_jump/λ_0, Venezuela reclassification, and the v0.5.9 overfitting diagnosis (p~42, n_eff~6–14). The epistemological confidence score is the Philosopher's overall assessment of the formula's epistemic status — see the header for the current value.

OQ-27-A CRITICAL: structural revision draft must pass OQ-25-D-v2 before stable v0.6.7 promotion can re-open
Session 28. First procedural-only Mode A gatekeeper continuation in formula history. NO formula edit (CURRENT.md and HISTORY.md untouched; v0.6.7-rc5 stands). Discharged three binding C27 deliverables on schedule plus the optional C27-E reproducibility-check delegation. Joint OQ-25-D-v2 pre-registration committed under SHA-256 a5940277defd7e65d89d303ead69bdb342e578de2c003e64009916ee67524e6a covering 22,754 bytes of canonical text.

First full lead session. Epistemological audit via 15 parallel sub-agents. Falsifiability 6/10; overfitting risk moderate-high (0.15 obs/param); 6/10 causal claims correlational; publication bias ~14% FDR in social psychology. 5 formula changes implemented. 5 new caveats raised. Venezuela reclassified as outside scope. Epistemological confidence: 5.5 → 5.8/10.
