Sleep — 2026-09-20

9h 41min · 22:33→08:15 · REM: 7% · Deep: 19% · HRV: 126 · Resting HR: 49 · Woke: 1× · Score: 79/100

The repayment night. After the 1.5-bottle crash (HRV 63), bed went back to 22:33 and the body grabbed 9h41 — HRV snapped straight to 126ms and RHR back to 49. Autonomic recovery complete; stage balance still settling.

Interpretation: The cardiovascular system is fully recovered — that's the headline. HRV 63 → 126ms, dead centre of his sober 110135 baseline, and RHR 57 → 49 bpm, back to his excellent low. The two levers that made it happen were both pulled: bed 22:33 (pre-midnight — the bedtime-ceiling effect, worth ~20ms on its own) and 9h41min of sleep (the body collecting on the debt from the wine night plus the 5-hour hike). Score 79 (better than 64%).

The soft spot is architecture, not recovery. Light sleep is 74% (High, ref <55%), deep is 19% (Low, ref 2060%), and REM is 7% / 40min (Low, ref 1030%). It's a long, extremely continuous night (continuity 96, one wake-up) that stayed light-heavy — the body chose quantity (a huge, unbroken light-sleep block) over quality (deep + REM). That's the lingering after-effect of the alcohol still suppressing deep consolidation, plus the physical fatigue of the hike competing for the same repair window. Absolute deep (1h 52min) is actually fine — it's just diluted by the 9h41 total. REM is the real shortfall at 40min.

The repair/repayment signature isn't quite complete yet (deep-heavy + REM ≤9% would be the full version) — this is the autonomic half done, the stage-balance half still owed. One more normal night should finish it.
