R4 Cycle Analysis: Sustained Field & Near-Baseline Lag Response

Reported global record coverage (UTC): – . The review contains 778 global records and 778 topology records.

Field & Structure Snapshot

Flow Impulse Profile

The topology series provides 777 measurable ΔMFI transitions. The first record supplies the baseline and is excluded from transition counts. 773 of 777 transitions (99.49%) fall inside the Stable Flow interval.

Dual Flow Shock Detector — R4
Classification ΔMFI interval Count
Positive Flow Shock ΔMFI > +12 0
Rising Instability +6 < ΔMFI ≤ +12 3
Stable Flow −6 ≤ ΔMFI ≤ +6 773
Falling Instability −12 ≤ ΔMFI < −6 1
Negative Flow Shock ΔMFI < −12 0

Intermediate upward excursions occurred on Sep 11 at 15:05:08 UTC (+6.22), Sep 16 at 19:05:07 UTC (+7.36), and Oct 04 at 23:05:16 UTC (+6.24). The latter was followed by a −6.41 excursion on Oct 05 at 00:05:09 UTC.

This final rise–fall sequence moved MFI from 84.28 → 90.52 → 84.11, leaving a net change of −0.17 at the reported precision. Both changes belong to the intermediate instability classes; no transition crossed either extreme Flow Shock threshold.

Lagged Structural Response

All 116 high-MFI observations contributed a nonempty 24–48h topology window. Their mean window weight was 0.2621, compared with the full-cycle topology mean of 0.2796. The reported difference is −6.28%, yielding an LCI of 0.9372.

The lag-window mean remains below the cycle baseline, but it falls within the analyzer's neutral LCI band of 0.90–1.10. Neutral is therefore a tolerance-based classification; it does not imply an exactly zero response. The reviewed lag statistic supplies no positive delayed-compression result for R4.

Structural Interpretation

R4 mean topology edge weight from September 4 to October 6, with several strengthening episodes, a large early-October peak, and a subsequent sharp decline.
R4 topology weight trend. Local increases coexist with substantial reversals; the lag-window statistic is classified as neutral.

R4 Dynamic Signature

Elevated MFI · Predominantly stable ΔMFI · Intermediate rise–fall sequence · Lag-window connectivity closer to the cycle baseline

Final Assessment

R4 is descriptively classified as an Elevated Field / Neutral Lagged Structural Response cycle. Field levels remained high, extreme Flow Shocks were absent, and the negative lag-window difference was smaller than in R3. Episodic topology strengthening is visible, while the reviewed statistics provide no basis for claiming a validated phase transition or a persistent compression regime.

Method & Evidence Scope

Numerical statistics are taken from the recorded R4 terminal outputs. Calculation rules were inspected in the supplied Python analyzers. The underlying JSON exports were not supplied for an independent recomputation.

LCI divides the mean of per-anchor 24–48h window means by the full-cycle mean edge weight. Every MFI > 90 observation is a potential anchor, including consecutive observations. A window is retained if it contains any topology record; complete coverage is not required. Windows can overlap, so the 116 usable anchors are not 116 independent shock episodes. The analyzer classifies positive LCI values below 0.90 as absorbing, 0.90–1.10 as neutral, and above 1.10 as compression.

ΔMFI compares successive timestamp-sorted topology records without normalizing for time gaps. Correlation and conditional means match each global record to the latest topology record at or before its timestamp, with no maximum matching gap configured. The recent slope is fitted over the last seven days against record position. These are descriptive rules; they do not establish causal responses or physical phase boundaries.
