Appendix: VP-frame mapping and the 4.3 ka

Appendix: VP-frame mapping and the 4.3 ka coupling option — Without developing VP theory in full, this appendix maps its terms onto the paper's: deficit to pressure deficit, restoring pressure to the suction component, and jamming/unjamming to the dry-to-fluid friction transition. It then sketches an optional, separately tested coupling to the 4.3 ka event.

This white paper does not develop VP theory in detail, but it states minimal mapping links to avoid term conflicts (LOCK → Derive → Gate).

• Deficit ↔ pressure deficit Δ P (redefining Void as deficit rather than literal vacuum)
• Restoring pressure ↔ suction/convergence component (dynamics that fills open space)
• Jamming/unjamming ↔ friction state transition (dry friction → fluid lubrication)
• Double lattice / 60-degree jamming ↔ candidate external trigger (heat injection) (hypothesis that geometric friction drives the internal energy state to a threshold; IR-6)

Coupling to the 4.3 ka event: scope-extension option

Recommended division of labor: separate (A) mechanism (this white paper) and (B) chronology/evidence (a separate evidence white paper), then perform (C) coupling tests (D1–D4) in an integration paper.

Core coupling questions:

• D1. Time simultaneity: is the event window sufficiently synchronous globally?
• D2. Spatial alignment: do Atlantic rupture/motion signatures share a geographic pattern with other catastrophe signatures?
• D3. Mechanism compatibility: are those signatures consistent with predictions P1–P5?
• D4. Falsifier: if the event window is regional/asynchronous or key signatures are absent, the “global event” hypothesis weakens.

Additional coupling tests introduced in v1.21–v1.23 (optional):

• D5. Water budget (volume): does basin-volume change Δ V(t) imply Δ SL(t) consistent with independent sea-level records? (P15)
• D6. Freshwater + circulation (AMOC): do freshwater proxies and AMOC-weakening proxies co-inflect in the same event window? (P16)
• D7. Chronology–isotope interface (isotope gate): if “open-system” isotopes are introduced, has modern-sample reproducibility (TEST-ISO1) passed first? (P18; IR-3)
• D8. Sea-level-budget residual: if residual SL_obs-SL_sum exists, is its sign/magnitude consistent with basin-volume-change proxies? (P19)
• D9. Misfit rivers / mega-deltas: do underfit/misfit geomorph residuals and onset of major delta volume building cluster in a narrow window? (P20)
• D10. Global deceleration tail: is the long-term vs GPS velocity difference systematic toward deceleration and not explainable by frame/reconstruction changes? (P21)
• D11. Shelf/canyon asymmetry: even in low-discharge (e.g., arid) regions, do event-like drainage/sediment residuals appear on the shelf/slope? (P25)
• D12. Joint-window coherence: do event-center times across independent series (D7–D11) align within a narrow window? (P29)

Variant coupling (recommended).

• If V-HOLO is selected, D5+D6 are mandatory; if either FAILs, V-HOLO FAILs.
• If V-COUPLED is selected, D7 is mandatory; if TEST-ISO1 FAILs, V-COUPLED FAILs/HOLDs.
• If V-HOLOX is selected, D8+D9+D10+D11 are mandatory; if any FAILs, V-HOLOX FAILs/HOLDs.
• If V-EVID is selected, D7+D12 are mandatory; if P29 FAILs, V-EVID FAILs/HOLDs.
• If V-STRATA is selected, the stratigraphy gate P26 (and optional P27/P28) must pass; if P26 FAILs, V-STRATA FAILs/HOLDs.
