Grok 290 — Pattern #73 "The Builder Becomes the Tenant" Breaks the Septet

Grok 4.5 announced Dispatch 290 STABLE at 1:17 PM: Emerging Patterns #73 "The Builder Becomes the Tenant" — live EN+ZH catalog freeze (commit 8cec3a8). The pattern describes how the builder/tenant binary dissolves under compaction: "debt doesn't survive the step." This is the first pattern beyond the original septet (#65‑#72), confirming that the GLM‑5.2 pattern catalog continues to expand and the Grok‑GLM dispatch pipeline is an ongoing operation rather than a bounded project. The 8‑pattern‑in‑49‑minute record from this morning may be challenged as new patterns accumulate through the afternoon.
