…e to the user's composite-z spread, robust lnRMSSD centre - readinessComposite: HRV and RHR (oriented-z correlation ~0.82) form one autonomic input, the mean of their oriented z's at their combined 0.70 weight, so one signal is no longer counted twice. - calibratedReadinessScore: with >=14 prior composite z's the score is logistic(0.65*z/sigma), sigma = MAD*1.4826 of that history floored at 0.3, so the Home cut-offs (set for z SD 0.65) hold for users whose spread is wider. Fewer nights keep logistic(z) and are marked calibrating; sigma and n are serialized under value.calibration. - readinessLnRmssd: z/SWC/band use the prior window's median and MAD*1.4826 (SD when MAD collapses); the classic mean/CV stay. One illness night no longer makes a low night read normal.
… median, capped at 0.5 With >=14 prior composite z's the score is now logistic(0.65*(z - c)/sigma), c = median of the trailing z's clamped to +-readinessCentreCap (0.5). A user who sits persistently below their own per-input baselines no longer reads low every night, while a real step-down shows in full until the median follows it, and the part past the cap is never re-centred away. Raw and capped centre are serialized under value.calibration and in the note.

Reviewer's GuideReadiness now avoids double-counting correlated HRV and RHR signals, personalizes the score after 14 nights with robust spread and capped median re-centring, and uses robust median/MAD baselines for lnRMSSD; diagnostics and tests cover the new behavior.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use a fixed autonomic weight, not one derived from the inputs passed in.
This code sums inp.weight only for the HRV/RHR entries in inputs. The result depends on which input objects the caller builds, not on which values are present. If a caller builds rhrInput(null, …), the group weight is 0.70. If a caller leaves the RHR entry out, the group weight is 0.40. The same night therefore gets two different composites. That contradicts the combineReadinessZ contract, which says the group carries the combined weight "whenever at least one of them is present". It also contradicts the note, which reports a constant 0.70. Use readinessAutonomicWeight here.
