expD: lead-lag scan — decay on synchronized pairs, splice-invariant ES-SPY, SPX content staleness

- 2006-07: real both-fresh diffusion (SPY->sectors +0.07..+0.148 FDR);
  2014-15: collapse to tiny residuals (a few FDR survivors -> expF;
  H08 expected-negative clause formally falsified, recorded)
- ES->SPY -0.032 both-fresh, identical across all 3 splice variants
- SPX->SPY +0.132 both-fresh (fresh_frac .996): content staleness beats
  print synchronization — H11 confirmed at scan level
- T3 amended: LOCF artifact non-monotone in staleness (inflates mid-stale,
  dilutes ultra-stale)

13 −*To be written after results exist. Must include the seven-field block and the evidence standard of CLAUDE.md §10 (never report an in-sample number as a finding).*
14 +Run: `results/expD_leadlag_scan/20260812T070742Z/results.json` (protocol
15 +pre-specified; alignment primitives §8.1-gated — the gate caught an
16 +interval-freshness bug before real data). All conclusions Level 0.
17 +
18 +## 1. The decay measurement (H07/H08 scan half)
19 +
20 +Both-fresh leads at +1min, 2006-2007 → 2014-2015:
21 +
22 +| Pair family | 2006-2007 | 2014-2015 |
23 +|---|---|---|
24 +| SPY → sector ETFs | +0.07 .. **+0.148** (all FDR) | −0.02 .. +0.028 |
25 +| SPY → mega-caps | +0.01 .. +0.03 (mostly FDR) | −0.015 .. +0.046 |
26 +| SPY → sparse names | +0.09 .. +0.12 | +0.06 .. +0.075 (still FDR) |
27 +
28 +Minute-scale market→component diffusion was REAL and large in 2006-2007 on
29 +synchronized samples, and collapsed by 2014-2015 — direct, open-data
30 +confirmation of the Chordia–Roll–Subrahmanyam convergence story at the 1min
31 +floor. The residual 2014-2015 structure is statistically detectable (huge n)
32 +but an order of magnitude smaller; several cells survive FDR, so the
33 +pre-registered expected-negative clause for H08 is formally falsified —
34 +recorded as such and handed to expF (costs will likely be decisive).
35 +
36 +## 2. ES ↔ SPY (H09 preview)
37 +
38 +corr(SPY_{t−1}, ES_t) = **−0.032** both-fresh, FDR-significant, and
39 +identical to 4 decimals across all three continuous-futures splice variants
40 +— the built-in robustness check held. Sign and size are consistent with
41 +minute-scale basis reversion rather than one-way price discovery (the +1
42 +ES-leads direction is ≈0). A genuine structural candidate for expF/candidate
43 +work; economically tiny.
44 +
45 +## 3. SPX → SPY: content staleness ≠ print staleness (H11 confirmed at scan level)
46 +
47 +SPY leads SPX by **+0.132** on the both-fresh subsample, with artifact share
48 +≈ 0 — SPX "prints" every minute (fresh_frac 0.996), so synchronizing on
49 +print times removes nothing: the staleness lives INSIDE the index
50 +computation (Fisher 1966, measured live). Confirms candidate 03's design:
51 +the correction must model constituent staleness, not print gaps.
52 +
53 +## 4. A T3 refinement for the taxonomy
54 +
55 +expB showed LOCF joins *inflate* leads for mid-stale names (+0.047). expD
56 +adds the other arm: for ultra-stale names the LOCF zero-return mass *dilutes*
57 +the measured lead (HTD: raw +0.048 vs fresh +0.073). The non-synchronicity
58 +artifact is **non-monotone in staleness** — naive joins can hide as well as
59 +manufacture lead-lag. Added to T3.
60 +
61 +## 5. Verdicts
62 +
63 +Clause (ii) falsified (tiny FDR residuals remain in 2014-2015); clauses
64 +(iii), (iv), (v) held. Hand-off to expF: the 2014-2015 FDR survivors, the
65 +ES→SPY basis effect, and the decay curve. expE (calendar) is next; its
66 +budget is pre-counted in research_gaps.md.

59 + remain FDR-significant at tiny magnitudes (XLF +0.028, JPM +0.046,

57 68 Interpretation
58 − <filled after the run — Level 0; survivors go to expF/expH>
69 + (Level 0.) Clause (iii) held: 2006-2007 retained real minute-scale
70 + diffusion — and its 2014-2015 collapse is the cleanest decay measurement
71 + of the project so far (XLK +0.148 -> +0.019). Clause (ii) FALSIFIED as
72 + pre-registered: several liquid/sector pairs survive FDR in 2014-2015 —
73 + statistically nonzero but economically tiny residual structure; to expF.
74 + Clause (iv) held: the ES->SPY effect is splice-invariant, a genuine
75 + basis-reversion-like microstructure candidate. Clause (v) held: the SPX
76 + "lead" is content-staleness, not print-staleness — synchronizing on print
77 + times cannot fix a computed index (H11 candidate confirmed in scan form).
78 + New T3 nuance: LOCF joins INFLATE leads for mid-stale names (expB) but
79 + DILUTE them for ultra-stale names (zero-return mass) — the artifact is
80 + non-monotone in staleness.
