What this is
V4's edge value T(π) was an additive sum over edges:
T_v4(π) = 1 + β · Σ_e∈π f(e) · g(n_e)
This assumed independence between sequential transitions. BRAID's structured reasoning graphs show that edges are not independent — they form verification checkpoints, feedback loops, and structured flows.
V5 replaces the additive sum with a path integral:
T_∫(π) = 1 + β · ∫_π F(γ) dγ
Why Path Integral?
The Independence Assumption Fails
The additive form assumes that edge e₃ contributes the same value regardless of whether you traversed e₁ and e₂ before it. This is often false:
Verification checkpoints: Some edges gate later traversal. If you haven't proven identity at e₂, the value of e₇ is inaccessible.
Feedback loops: Paths can revisit vertices with changed meaning. The second visit to a node carries different value than the first.
Non-local correlations: A choice at step 3 affects value at step 7. The edges are coupled through the path history.
BRAID Evidence
BRAID's structured reasoning graphs exhibit all three patterns:
- Some reasoning steps validate preconditions for later steps (checkpoints)
- The Solver may revisit parts of the graph with updated context (loops)
- Early reasoning choices constrain later possibilities (correlations)
The additive form can't capture these structures. The path integral can.
The Path Integral Form
T_∫(π) = 1 + β · ∫_π F(γ) dγ
| Symbol | Definition | Domain |
|---|---|---|
| π | Path through sovereignty lattice | Continuous or discrete path |
| γ | Path parameter | [0, 1] |
| F(γ) | Path density function | ℝ⁺ |
| β | Scaling coefficient | ℝ⁺ |
The Density Function F(γ)
F(γ) captures the value density at each point along the path. It can encode:
- Local value: What is this edge worth at this point in the path?
- Context dependence: How does path history affect this edge's contribution?
- Checkpoint gating: Is this edge accessible given prior traversals?
- Loop adjustment: How does revisitation change value?
V4 Reduction
When edges are truly independent:
∫_π F(γ) dγ = Σ_e∈π f(e) · g(n_e)
The path integral reduces to the additive sum. V4 is a special case of V5.
Connection to BRAID
Generator-Solver Split
The path integral naturally handles the BRAID architecture:
- Generator proposes: Creates a reasoning graph = proposes a path π
- Solver executes: Traverses the path = computes ∫_π F(γ) dγ
- Value accumulates: The integral measures actual traversal value
Structured Graphs
BRAID graphs have:
- Defined entry and exit points
- Conditional branches based on intermediate results
- Verification steps that must pass before continuation
These are exactly the patterns the path integral captures.
Mapping to PVM-V5
| Concept | V5 Term |
|---|---|
| Additive edge sum | T_v4(π) (V4, special case) |
| Path integral | T_∫(π) (V5, general case) |
| Path density | F(γ) |
| Verification checkpoints | Gating in F(γ) |
| Feedback loops | Loop contributions in integral |
| Non-local correlations | Context dependence in F(γ) |
| Generator-Solver | Path proposal / path execution |
Implications
For Path Design
Paths should be designed with integral value in mind:
- Verification checkpoints should be placed where they maximise downstream value
- Loops should only occur when they add value (not just cycles)
- Correlations should be explicit, not accidental
For Value Estimation
Estimating T_∫(π) requires understanding the full path, not just summing edges:
- Path history matters
- Context propagates
- Checkpoints can gate large value regions
For Privacy
The path integral provides more accurate value measurement:
- Surveillance that interrupts checkpoints loses access to downstream value
- Loop structures can confuse adversarial path analysis
- Non-local correlations mean partial path observation is less informative
Conjecture Status
C3 (V4: edge value additivity): Challenged. The path integral form better captures observed structure in BRAID reasoning graphs. The additive form is retained as a special case for uncorrelated paths.
Proverb
"The path is not the sum of its steps. Each step changes what the next step means. The integral remembers what the sum forgets."
