Twelve sessions · Stripe-shaped staff loop · 24 days out
Tracking Approaching for a Stripe-shaped staff system-design loop. Strongest on Recovery; the one gap left is Framing.
The trend on Recovery is your most reliable signal — you have crossed the bar in five of your last seven sessions. Framing is the dimension to close: every session where you missed the bar, you went architecture-first. Two prescribed framing drills are queued for tomorrow. Loop in
24days.

What changed this week · written from your last three scorecards
Recovery is now your strongest dimension — you crossed Above bar on session 042 by restating the thundering-herd failure mode in your own words before the room had to suggest a bound. The remaining gap is Framing. Every session where you missed the bar, you drew architecture before quantifying load. Two prescribed framing drills should close it inside a week.
The prescription engine queued "Restate the read/write ratio inside ninety seconds" for tomorrow and "Quantify three numbers before the first box" for Friday.

Progress is a competence chart, not a casino. No streaks, no XP, no badges. The only number that matters is whether your framing improved from session to session.
