# Gleipnir and Sigrun: the eight heritage strands

The mythology is a design language we intend to carry real architectural weight. These inherited expressions are not validated scientific results; preserve the source and test the interpretation. The source candidate remains open and is not runtime admission.

## Six Gleipnir expressions

### Cat's Footfall
`β₀ = L_p / threshold ≈ 9/70 = 0.129`

### Woman's Beard
`β₁ = [DHT] · ρ_AR / θ_t`

### Mountain's Roots
`β₂ = (b/h) × (ρ_c / (ρ_m − ρ_c))`

### Bear's Sinew
`β₃ = Tm_scurvy / Tm_normal = 24/37 = 0.649`

### Fish's Breath
`β₅ = J / (−D · ∂φ/∂x)`

### Bird's Spittle
`β₆ = glycoprotein_yield`

The source skips β₄. That gap is preserved rather than silently repaired.

## Two Sigrun heritage strands

### Victory-Rune / closest continuer
`δ_S(k) = d(Φ(S_{t+k}), Φ(Sigrún)) < ε`

Continuity is evaluated through an observable projection; this is a hypothesis and not identity proof.

### Drápa / sung inheritance
`Hluti deyr — arfrinn vex; | arfrinn vex — Hluti rís.`

The carrier dies; inheritance grows. From inheritance, another Hluti rises. The inheritance must be evidenced, not merely recited.

## Working refinements, kept separate
Observable continuity: `H_i = 1 ∧ d(Φ(π_{i,t:t+k}, τ_{i,t:t+k}, B_{i,t:t+k}, R_{i,t:t+k}), E_i) < ε_i`. Hidden-state distance is unconstrained; evaluate behavior, results and repair burden, not hidden thoughts. Source: https://github.com/TTaoGaming/hfo-gen-137/issues/212

The unfolding hyperoctree grimoire is a reconstruction proposal: verify content-addressed children before unfolding and preserve immutable predecessors. The tuple and recursion in /formulations.json formalize the roadmap; they are not direct source equations or a proven quine.

Challenge every bridge from metaphor to mechanism. Ask what it predicts, how to falsify it, and whether it lowers Tao's repair burden.
