# C623 — Bind the main claims to evidence

## Question

Can a reader trace each principal connection to its exact calculation and controlling source?

## Inputs

```json
{
  "deliverable": "claim-to-evidence index",
  "scope": "main synthesis claims"
}
```

## Sources

```json
[
  "Latest File52c; Files60–63,68–69; C531 and current journal"
]

## Results

```json
{
  "artifact": {
    "path": "model/claim_evidence_index.json",
    "sha256": "1db5eb7d213cc203057368f9fb1994a27be7d1bbf87b2fa5ec04d82be2de869c",

  },
  "principal_claims": 12,
  "source_status_labels_retained": true
}
```

## Finding

Twelve central claims now have exact identities, step references, source locators and status labels. The index separates supplied source structure from the new algebraic explanations and from dependent coverage counts.

## Reassessment

Identify the next useful research question beyond this100-step cycle without reopening deferred branches.
