This publication introduces the concept of Stream in the Karmil Streams System (KSS) as a foundational conceptual, mathematical, and methodological object. The article defines a Stream as an energetically grounded, phase-dynamical, structurally integral state of an already formed Binary Field. It presents the genetic order of Stream formation, the distinction between pre-stream, stream, and post-stream states, the role of Eₛtr and Bₒrg, the closed SP-12 coordinate kernel, Binary Analysis, the Ledger no-loss principle, bridge-based representability, and the implementation-facing status of SAS (Stream Analyzer System). The article is intended as a foundational reference for KSS as a Stream-based framework for structured dynamic systems and for later proof-route applications. It distinguishes internal KSS verifiability from external mathematical verifiability. Internal verifiability is based on the protected Registry kernel, SP-12, EB Block, Binary Analysis, Ledger preservation, bridge representation, and non-circular route construction. External mathematical verifiability is formulated through the ED-OBS-LED-TE-CC proof-template, where External Domain, Observation, Ledger, Transfer Estimate, and Continuation Criterion must be explicitly defined and closed before any external theorem-level claim can be made. The article also records the historical origin of KSS from musical directed reading, including the global invariant mask Δ = T-T-S-T-T-T-S, the transition from early ascending/descending readings to AS-DS, and the later development from StreamAnalyzer to SAS. It treats 3D Euler, 3D Navier-Stokes, and KSS-Turbulence only as advanced proof-route cases within the broader class of structured dynamic systems. No external global solution of these problems is claimed in this article. This publication does not reproduce the full KSS Registry, does not modify SP-12, does not enlarge EB Block, and does not treat SAS visualization or reporting as proof. It establishes the conceptual and methodological foundation required before later KSS Registry, proof-route, turbulence, external dynamics, and SAS-oriented publications can be read coherently.
