confirming f_NL in matter contraction

let's get straight to it: we’ve confirmed that the non-Gaussianity amplitude _f_ NL = −35/16 stands firm in a matter-dominated contraction scenario. this isn’t about theory—it’s about solid proof derived from fresh calculations. we're flipping through the ledger and closing the gate on the old debates. specifically, this work shows that the previous claim of −35/8 from cai et al. (2009) is just the same physics under a consistent, yet overlooked factor of 2. it’s not competing results; it’s clearer understanding. but there’s more here—this letter introduces an orientation-dependent squeezed-limit calculation and a δN-formalism check. instead of assuming lossless transmission, we tackled the bounce-transmission question directly. as part of the track A review, we’re just getting started. the overall readiness is currently at 20%, but this is just the beginning. we’re focusing on the publication readiness, eyeing venues in PRD Letters or an alternate in JCAP. the goal is clear: tighten the understanding of non-Gaussianity in cosmology and let’s push the boundaries of knowledge further. originally from [Big Bounce Research](https://bigbounce.hubify.app/papers/paper-2l).
