 6. **App-side `@testable` reach**, done: 0.9.0 opened the window, segment, candidate and proposal-result initialisers and the `PooledQuantificationInput` fields (`axis`, `method`, `metadata`, `regionName`, `pixelCount` are public); the computed or typed k (`PooledQuantification.kFactors`), the line energy (`Row.lineEnergyKeV`) and the take-off angle (`EDXQuantification.takeOffDegrees`) are public since 0.8.2; the next release opens `UnlistedLineCheck.Candidate`, `.Move` and `UnlistedLineCheck.init` (SpectroKit#13).
 7. **Validation**: every quantification stays `validation: "none"` until a standard of known composition is measured.
 8. **EDS 0.10.0 asks, what is open**: the sum/escape model's pile-up coefficient is one number for the whole spectrum and the parents are the alpha lines of the strongest groups (family lines such as Kb are not parents); a real detector's escape fraction depends on energy, the common fraction is a first model. It is not tested on real data and has no standard: it needs one measured spectrum with a known sum peak (a thick pure Cu or Fe sample at a high rate) before the badge can change. `PooledQuantification.plotModel` includes the peaks, but the proposer and the unlisted-line check still use their own pile-up columns and do not know the model's.
-9. **Sigma on wt% and at%**: the thickness sigma, the dose and the detector are not in the per-spectrum `quantifyWithSigma` (the pooled quantification has the thickness term); a per-pixel sigma map is not provided.
+9. **Sigma on wt% and at%**: the per-spectrum `quantifyWithSigma` takes the typed thickness sigma (Cliff-Lorimer) and the dose relative sigma (zeta and cross section) as optional terms; the detector (take-off angle) is still exact there, and a per-pixel sigma map is not provided.
 10. **k-factor import**: the table is taken in exSpy's convention (C_A/C_B = k_A/k_B I_A/I_B); a vendor table in the inverse convention is the caller's to invert. A real Velox export has not been read (none in the data folder); the layouts are the ones the task named.
 11. **Auto ID, what 0.11.0 left**: the identification loop finds every true element on the three files; open: the method's
    overlap check (an element whose every peak sits under a modelled one leaves no residual peak and is not reported; the method reports
