Part of #9

Docs only, for the merged #41 and #42.

  • docs/parity.md: Images.interpolate gets its own row, partial (method "fft", both normalizations, pinned at rtol 1e-7 by tools/pins/image-interpolate; "spline" not offered); DiffractionPatterns.interpolate stays missing. integrate_disc names interpolate:. The Grid row says lengths off vDSP that factor into 2, 3, 5 and 7 run the mixed-radix FFT. Totals recounted from the table: 129 rows, 38 present, 40 partial, 51 missing; the study split was stale and is now 12, 7, 8.
  • docs/open-items.md: the FFT item names what is left (a prime factor above 7, 506 squared, 1.6x NumPy); the Detector and noise follow-ups from 0.4.0 #9 item drops integrate_disc(interpolate:) and adds the spline method.
  • tools/README.md: the pins/image-interpolate generator row.

Remains: the azimuthal_average (#39) and LineScan defaults (#40) parity rows and their tools rows, once those PRs merge.

Test evidence: docs only; the CI gate staying green is the test.

…he mixed-radix FFT

parity.md: Images.interpolate gets its own row, partial (method fft, both normalizations, pinned at rtol 1e-7 by
tools/pins/image-interpolate); DiffractionPatterns.interpolate stays missing. integrate_disc names interpolate:. The Grid
row says lengths off vDSP that factor into 2, 3, 5 and 7 run the mixed-radix FFT (#42). Totals recounted from the table:
129 rows, 38 present, 40 partial, 51 missing; the study split was stale (now 12, 7, 8).

open-items.md: the FFT item names what is left after #42 (a prime factor above 7, 506 squared); the #9 item drops
integrate_disc(interpolate:) and adds the spline method.

tools/README.md: the image-interpolate generator row.

The azimuthal_average (#39) and LineScan defaults (#40) rows wait for those PRs to merge.

Done: rows for #41 and #42. Next: rows for #39 and #40 when they merge.
