ɹıuƃs · the critique (upside down)

READINGPage 11 of the upside-down run. Each node is a page, placed on the ring that matches its severity: inner = solid, outer = weakest. Tap a node to read its note.

what works	what's weak
The 208 page found that v40 is not flip-symmetric: the row counts are symmetric, but 2 atoms (ranks 0 and 194) land on RESERVE cells under a vertical flip (ranks 0 and 193 under 180°). Read in rank order, a vertical flip keeps parity on all 206 (104 cancel / 102 survive, 2821); 180° breaks it on all (103/103, 2847). Exactly 13 of 26 letters are 180° ambigrams (with an m↔w font caveat), and the cipher's surviving value goes 235 → 191 with Σcoef 13 kept. Orion flips at southern latitudes from real coordinates, and the Rayleigh–Taylor σ is exact.	Several self-checks are tautologies ("by construction", 0.4 < 1, three creatures drawn) on the Cassiopea, hanging-life, magnetic-reversal and shells-from-below pages. Stratton's durations, the Cassiopea sleep study, sloth organ adhesions and Kohler are from memory, unverified. The geodynamo is a Poisson toy. The Thatcher face is a schematic line drawing.
Upside down is kept distinct from inside-out: nesting order is preserved under rotation, and the shells page checks it.	Carried and still NOT done: measured ice/water, full Mie, Karkoschka, methane, lapis/YInMn, unique yellow, measured dye spectra, Stockman–Sharpe afterimage, measured Wu asymmetry.

READINGNext time: replace the tautological checks with computed ones, verify Stratton (Psychological Review 1897) and Nath et al. 2017, and ask Dave whether the two off-disc atoms (ranks 0 and 194) are intentional asymmetry or a v40 artefact.

Engine: Dave's DurableAnchor kernel, ported faithfully to the browser with Web Crypto SHA-256 and an in-memory record store (exclusive-create, so concurrent reservations are refused; fsync has nothing to flush). The ledger starts empty on each load. Every state change on this page is a reservation (id, epoch, sha256 of the state), and the head shown above chains them all from sha256('ROOT0:P369:GENESIS').
