# C630 — Run the pre-closure verification gate

## Question

Do all98 completed records replay exactly with current source identity and scope checks intact?

## Inputs

```json
{
  "through": 629,
  "required_steps": 98,
  "required_snapshots": 28
}
```

## Sources

```json
[
  "Sequential journal; exact step scripts; current originals; verifier"
]
```

## Opened utc

## Results

```json
{
  "verification": {
    "status": "PASS",
    "sequential_steps": 98,
    "step_checks_replayed": 241,
    "source_snapshot_hashes_verified": 28,
    "current_source_copies_checked": 29,
    "journal_hash_chain_verified": true,
    "second_inverse_guard_violations": 0,
    "replay_writes_blocked": true
  },
  "report_sha256": "2ad1c3cae47304c9f4eca8f1ea581f4250b8cc78f61668653878c64f25e93f4e"
}
```

## Finding

All98 completed records replay exactly with241 named checks,28 source snapshots and29 current copies verified. The hash chain and predecessor match; replay is read-only and no second-inversion guard violation occurred.

## Reassessment

Close the100-step cycle and bind the deliverables, then execute the final100-record verification.

## Checks

```json
{
  "passed": true,
  "sources": true,
  "scope": true
}
```
