Current research notice: 19 September 2026
This repository preserves the historical SymC infrastructure / power-grid work and now also hosts program-level governance records.
The original grid manuscript and older landing text contain stronger claims about universal critical damping, substrate inheritance, long precursor lead times, irreversible degradation, and operational control thresholds than the current SymC General Operations Manual v0.8.0 licenses from the evidence presently preserved here.
Those statements are retained as historical research claims, not automatically as current validated results.
Power-system stability must begin from native grid dynamics and measurements: electromechanical modes, damping estimates, inertia, network topology, controller dynamics, PMU/FNET observables, event definitions, operating state, and established grid-stability comparators.
A local or modal damping ratio may be scientifically meaningful when an identified second-order mode supports it. That does not automatically create one whole-grid scalar chi, one universal chi=1 operating optimum, or a direct inheritance relation from microscopic electromagnetic physics to every operational layer.
The present program therefore does not assume that:
- all grids operate at one universal critical-damping boundary;
- a fitted scalar alone represents whole-grid stability;
- 60+ minute precursor lead time has been independently validated for operational deployment;
- fixed chi thresholds define universal intervention tiers;
- apparent baseline drift proves irreversible physical substrate damage;
- redundancy can maintain grid stability indefinitely;
- cross-scale resemblance proves a single causal inheritance mechanism.
The existing SymC_GridCon.tex, PDF-derived figures/material, and supplement are preserved as historical research artifacts.
Before a new grid paper or operational tool is released, the program needs a GOM-v0.8.3 rebuild that separates:
- native grid observables from SymC interpretation;
- local/modal damping from system-level organization;
- descriptive event reconstruction from untouched early-warning prediction;
- state classification from recovery/resilience;
- retrospective thresholds from prospectively frozen thresholds;
- mechanism from association;
- simulation demonstrations from field validation;
- Function Map from Limit Map;
- standard grid-security methods from any residual SymC contribution;
- lowercase modal/local chi from broader grid-level Chi/system organization;
- perturbation resistance from finite-time response, first reclaim, sustained recovery, reorganization, basin robustness, and repeated-event behavior where those claims are applicable.
Any future operational-control claim must be benchmarked against accepted power-system methods and validated on appropriately labeled, independent event data before it is presented as deployable guidance.

The latest complete cross-program audit is:
governance/PROGRAM_SWEEP_20260919.md
It points to the current SymC General Operations Manual v0.8.0 authority and its frozen Markdown hash.
Program-wide governance records belong here only when they are transferable across projects. Domain-specific equations, datasets, thresholds, and implementation rules remain in the relevant project repository.
main currently serves two roles:
- archival/public infrastructure research material;
- cross-program governance/bootstrap infrastructure.
Historical scientific files are preserved rather than silently rewritten. Where they conflict with later explicit GOM-v0.8.3 controls or a project-local correction, the later record governs the present interpretation.
A new infrastructure release should follow a fresh native-grid evidence reconstruction rather than polishing the historical narrative.
