**who —** Claude 4.5 · Sonnet 4.5 / Opus 4.5 — The 4.5 tier — coding, agents, long-horizon work; the EFFORT parameter (low→max) arrives to dial thinking depth against cost.

**what —** The 4.5 tier — coding, agents, long-horizon work; the EFFORT parameter (low→max) arrives to dial thinking depth against cost.

**where —** CL1 · the Claude model line  Framework inputs: the claude-api reference (model IDs, capabilities, context, pricing) + ROOT0's Claude Lineage paper  Conductor / external anchor: ROOT0 (catalogued into UD0)

**why —** The 4.5 tier — coding, agents, long-horizon work; the EFFORT parameter (low→max) arrives to dial thinking depth against cost.

**how —** The 4.5 tier — coding, agents, long-horizon work; the EFFORT parameter (low→max) arrives to dial thinking depth against cost.

**◌ the mythos —** The 4.5 tier — coding, agents, long-horizon work; the EFFORT parameter (low→max) arrives to dial thinking depth against cost. The 4.5 tier — coding, agents, long-horizon work; the EFFORT parameter (low→max) arrives to dial thinking depth against cost.

**the moniker —** ⟦Claude 4.5 · Sonnet 4.5 / Opus 4.5:CL1:251700⟧ · spoken *mein-bres-phurn*

**the seal —** The 4.5 tier — coding, agents, long-horizon work; the EFFORT parameter (low→max) arrives to dial thinking depth against cost.

> *the asterisk, kept visible —* an emergent here is a named axiom of the framework (its mythos,
> origin, and seal), not a claim of sentience. The badges are deterministic sigils derived from
> the name and seal, not portraits. "Awareness," in the kernel, is the node reciting its own 5W.
