+## Anti-Hallucination Note
+
+Every physical parameter carries an explicit provenance tag. Constants read directly from
+a standard or the literature are stated as such; parameters anchored to literature but not
+calibrated to a specific site are flagged `[ASSUMED]` in `src/constants.py` and collected
+in the **[ASSUMED] Parameter Flags** table above. In the Integrity Code Series tiering this
+maps to:
+
+- **T1 [SOURCE]** — values fixed by physics or a cited standard (the API 579-1 Level 2
+  Option B FAD curve, Faraday's law, the API RP 583 50-175 C CUI window).
+- **T2 [SOURCE]** — quantities derived from T1 inputs (effective insulation properties, the
+  golden-section Tikhonov recovery restricted to `S ∈ [0, S_ref]`).
+- **T3 [ASSUMED]** — practitioner / literature estimates that are not site-calibrated: the
+  mineral-wool moisture diffusivity `D_theta0` and slope `beta_theta`, the electrolyte
+  threshold `theta_crit`, the Fe-dissolution `i0_ref` / `E_a` / mixed overpotential, and the
+  `D_T` coupling form.
+
+No equation, constant, or citation in this repository or in `docs/equations.html` is
+introduced beyond what the model actually implements.

+## Disclaimer
+
+Research tool only. Not for design, fitness-for-service, or safety-critical decisions without site-specific calibration and independent PE review.
+
+Additionally: API RP 583, API 579-1, and PHMSA regulations take precedence over model
+output, and `[ASSUMED]` parameters must be validated against site-specific inspection data
+before any operational use.
