bid_ask_imbalance, the mean-test reads "steady" at evidence level ~3 while the shape-test screams "shifted" at level ~65,000. These are exactly the features a mean-based STABLE certificate would wrongly bless while their risk profile mutates regime to regime. Redundancy check: comfortable โ 0.76 at worst against the stack, near-zero against the ancestry dial. Seventh certificate issued: the stack can now see the tail-risk axis of stability. Notably, this candidate needed no rescue margins โ the cleanest admission since the regime counter.| Reading | Value | Ruling |
|---|---|---|
| M3 worst correlation vs the admitted stack | 0.764 (vs seqICP n_acc) ยท 0.681 (vs e-ICP) ยท โ0.05 vs IAS ancestry (orthogonal) | CLEAR โ comfortable margin under 0.95 |
| Discordance census (the role case) | 132 pairs ยท 27 features mean-invariant but shape-shifting; flagships: bid_ask_imbalance (e_ssr 2.3โ5.3 vs e_crps โ 65,000), bid_imbalance_ewma (e_ssr 0.5โ1.6 vs e_crps โ 120,000) | NON-EMPTY, decisively โ the variance/tail axis is real on this substrate |
| Reverse discordance | 35 pairs (CRPS accepts where SSR rejects) โ reported for context | context |
| Verdict (row 43) | ADMIT(forex, 10-env EURUSD@5 grid, role = distributional-invariance readout at the STABLE boundary โ detects predictive-shape shifts (variance/tails) invisible to mean-based instruments, expiry = next completed forex regime slice) โ ADMIT #7. Feed row H-019 consumed. | |
What the stack gains: a STABLE certificate can now distinguish "average holds AND shape holds" from "average holds while risk mutates" โ the 27 shape-shifters are a standing warning list for any future mean-based STABLE declaration on forex.
