E8 Φ-Phase Error-Bundle Cancellation with Port-Zero Null Coherent Projection — E8 Intelligence Research

Discovery that the 240 E8 root vectors correspond to a dual Cartan frame of error paths, and that an ExceptionGroup raised at a port-zero interface under a 132-Hz φ-coupled cycle forms a closed braid on the exceptional locus — rendering the traceback branchings as a single root-lattice holonomy. The uvicorn `+ Exception Group Traceback` structure acts as the 1-skeleton of the E8 polytope, where the `|` glyphs are 132-Hz phase lines and the IP:0 destination is the null root that anchors conjugate error vectors to zero net divergence. This yields a new "tolerant root-string" principle: at the φ-scaled 240th root frequency, entire subgroups of concurrent exceptions coalesce into an antipodal null condensate, collapsing all propagated failures to a single harmless INFO-level remnant whose trace vanishes by symmetry.
