Summary

Adds knowledge/gradient_witness_evaluation_point.md: a decision rule for reading a gradient.json FD verdict when the evaluation point sits on a symmetry of the problem. It covers:

• the border-relocator tie gradient (PyAutoArray#672);
• the Isothermal core at an odd-grid point at the prior medians;
• why the phase-6 campaign cells are clear of both;
• the point mislabel on the standard cells;
• the smallest-step autodiff-vs-FD check.

It cites the autolens_profiling#515 research note at its pinned commit (9af783c9).

Scripts Changed

• None. Documentation only: knowledge/gradient_witness_evaluation_point.md. It is listed automatically in the setup browser's knowledge links.

Test Plan

• python -m pytest tests -q (380 passed) and bin/pyauto-pulse check --offline pass locally.
