Awareness would be any form of agency, goal seeking, or loss minimizing.
As Briggs–Rauscher reactions can eventually lead to Belousov–Zhabotinsky reactions, the system can maintain homeostasis with its environment (and continuing to oscillate) by varying reactants in a loss minimizing fashion.
This loss minimizing would be done during scarcity to limp towards an abundance phase.
This is the mechanism that hypothetical tidal pools batteries would had exhibited to continue between periods of sunlight/darkness/acidity that eventually gets stratified as a resilency trait.
I'm not sure what your argument is here, except stating an opinion that loss minimization is equivalent to agency. But even if that was accepted, which is a huge stretch, it doesn't stretch all the way to awareness.
I'm not sure if you're familiar with the work from the lab of Mike Levin at Tufts but I'm betting you'll find it interesting if not. Here's a taste https://pmc.ncbi.nlm.nih.gov/articles/PMC6923654/
While I disagree with your notion that this is explicity due to gravity, the rest of your argument seems to align with some of this lab's work. Learning can be demonstrated on scales as low as a few molecules, way below what we would normally call "life".
