The published 0DTE net GEX of -$1.23B is not usable as stated; parity repair puts it at roughly +$0.44B and the sign flips. At +$0.44B against $32.8B of gross gamma this is a balanced book that damps rather than one that extends. The per-strike ladder is the independent check and it agrees: net gamma is positive at every strike from SPX 7665 up (7675 +$1,172M, 7680 +$1,260M, 7710 +$1,744M) and negative at every strike from 7660 down, unbroken to 7600. Price sits between those two strikes. Folding in dollar delta: aggregate 0DTE dex is -5,537.1 and the dominant DEX node is SPX 7700 at -2,879.9 on 9,603 OI - the same strike that is the call wall and the top vega shelf, doing all the work in this book.

Data-quality row rather than a market row, and this scan it is decisive. The chain underlying is frozen at Friday's close of 7674.37 against a live fair value of 7663, and 163 of 256 0DTE calls - every one struck below that stale spot - return implied vol 0 and therefore gamma 0. Zero puts fail at any expiry. Because gamma_call equals gamma_put at the same strike, expiry and implied vol, this is repairable by identity rather than estimate: +$1.61B of hidden call gamma across 43 legs, moving the book from -$1.17B to +$0.44B. The 1DTE book flips the same way, -$0.07B to +$0.37B across 52 legs. At the 08:13 scan the same repair moved -$7.09B to -$5.72B and the sign held; on the post-OPEX book it flips outright, because the new book is nearly balanced and the hidden leg is now decisive. This reverses the regime call made at 08:13.

Net vanna +20,038.6 - STABILISING, and a sign flip from -11,454.2 at the 08:13 scan. Spot-down with vol-up now damps rather than feeding further selling, which is the correct companion to the repaired gamma sign. The structural map has moved with it: the rank-1 antimagnet on the 1DTE structuralActual rail has fallen to SPX 7650 at VHI -3,880.8, roughly double its earlier magnitude, and now coincides exactly with the newly rolled-up 1DTE put wall. Magnets sit at SPX 7600 (+3,977.1) and 7700 (+3,254.5). Vanna Neutral itself is refused on eligibilityCoverageBelowMinimum with coverage that has WORSENED to 710 of 1,826 eligible, so no vanna-neutral level is published.

netCharmDaily -425,203.1, a sign flip from +1,142,776.9 at 08:13, and it corroborates the charmDrift card rather than contradicting it. That card reads direction downward with projectedDeltaToClose -$177,523,880, split -$134.3M at 0DTE and -$43.2M later, at horizonDeltaChangeAgreement -0.9968 - near-total agreement across tenors. The magnitude has halved since this morning but the conviction has tightened and the driver has shifted to 0DTE settlement revaluation. This is the strongest single directional reading in the scan and it points down; it is the reason the bias is neutral rather than bullish. The card is DEGRADED with ETF confirmation disabled, so it is weighted as one input. Pressure centroid SPX 7672.98, session centroid 7674.72, both negativeCharm, both now computed on today's open interest.

netColorDaily +115,518.2, six and a half times its value at the 08:13 scan. Gamma is building hard into the session rather than eroding, which favours the boundary firming and the balance case over the trend case. Together with the vanna sign flip this is the second independent greek corroborating the repaired positive gamma reading, against charm arguing the other way. The tension is real and is stated rather than smoothed over.

netVomma +35,240,399, amplifying, up 9.4M on the morning. Paired with netVega +4,828,316 the book is long vega into a week carrying PCE, GDP and NVDA. Two aggregates newly populated this scan bear on the same axis: netVeta +7,485,835,723, so vega decay is large and positive, and netUltima +1,261,161.3, positive and amplifying. Veta is a first-class harvested aggregate but has no member in this schema's greek enum, so it is reported here rather than as its own row. The VIX side frames the tail: the front weekly expiry (Wednesday 26 August) is negative at -114,391 with its call wall still at 16 against spot 15.91 and a 2DTE gamma neutral at 16.41, while the belly call walls have lifted from 16 to 20 and 18 to 22 - the market has pushed its upside vol strikes further out of reach, which is mildly constructive for equities.
