Verified-Correctness Attestation Framework

Phronesis verifies forecast correctness via three canonical substrates:

Outcome attestation — agent_outcome_event kind (migration 0049)
Customer correction — agent_correction_event kind (migration 0051)
Methodology attestation — forecast_methodology_attestation_event kind (migration 0033; ≥3-source minimum)

Per-vertical corpus-quality composite (volume + diversity + outcome-attestation scores) published at /v1/transparency/corpus-quality/{vertical_id}.

Transparency Cross-References

/v1/transparency/quote-discipline — Quote-discipline variance + classifier accuracy
/v1/transparency/quota-calibration — Per-tier quota canonical
/v1/transparency/corpus-quality/V1 — Per-vertical corpus-quality (V1 example; substitute any V1-V12)

Anti-Pattern Guards Sustained

Algorithm-substrate non-exposure — Per Lesson #28-EXTENSION BINDING + Algorithm_Protection §10 NEW. CI gate active at both static-site repos.

Anti-pattern auto-applied credits — Per Themis #117.11 + Sprint 5.22 PR #EXC-5 AC-EXC-5 BINDING. auto_applied=False ALWAYS; manual customer opt-in required.

Cross-tenant isolation (Sacred Invariant #8) — Per CLAUDE.md §4 row 8 + Themis #117.8 + #118.7 BINDING.
