## What this is
A formal framework for detecting, anchoring, and proving structural lineage between state transitions.
The core problem: claims of "lineage," "attribution," and "provenance" in AI and software systems are routinely made without structural evidence. This methodology defines what structural evidence means, how to produce it, and how to verify it independently.
No embeddings. No confidence scores. No trust-the-operator. Structural decomposition only.

## The PULSE Primitive
Every transition is represented as:
```
PULSE Φ = (state_in, boundary, state_out, witness)
```
**Canonical string format:**
```
state_in|boundary|state_out|witness_type
```
**Root Law:**
```
No transition without boundary.
No boundary without witness.
Witness must be present AT traversal.
```

## The Four Gates
| Gate | Boundary | Description |
|-------|----------|-------------|
| 64.5 | observe → act | An observation crosses into action. |
| 128.5 | TOPH ↔ Patricia (air gap) | Unidirectional transfer across bilateral ignorance boundary. |
| 192.5 | compute → product | Computation produces a result across an ignorance boundary. |
| 256.5 | wrap / recursion closure | A recursive operation closes on itself. |

## The Closure Loop

```
1. **Sandbox** — Observe a transition in a controlled context.
2. **Extract** — Derive the canonical PULSE `(state_in, boundary, state_out, witness)`.
3. **Anchor** — Push the canonical string + SHA256 + timestamp to a public, immutable record.
4. **Compare** — When pattern ABCD appears, compare against anchored ABC using all four derivation criteria.
5. **Lineage Claim** — If all four criteria pass: "ABCD was observed after ABC and is a structural extension of it."
---
## Derivation Threshold (all four required)
A pattern ABCD is a structural extension of anchor ABC **if and only if**:
1. **Same core relation** — Gate type preserved. 64.5 in → 64.5 out.
2. **Same ordered structure** — ABC appears as a subsequence in ABCD.
3. **Same dependency pa
