# C1203 — Calculate the SP composite fibre thresholds

## Question

How far below each exact cap can an uncapped life imitate its rounded clipped output?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1202",
  "C1143"
]
```

## Results

```json
{
  "thresholds": {
    "path": "model/SP_cap_round_fibre_thresholds.json",
    "sha256": "0e5375ce43907dc1ce63d0b6d0786a30ed3ddaa91d3fbf3682294d53aea30dbb",
    "bytes": 752
  },
  "minimum_inputs": [
    843,
    718,
    653
  ]
}
```

## Finding

Jared’s845 output permits any life at least843; Methuselah’s720 permits at least718; Lamech’s655 permits at least653. Rounded output alone does not recover the original962/969/777 ledger or generally the clipping status.

## Reassessment

Determine how a known clipping branch changes the information needed for reconstruction.

## Checks

```json
{
  "thresholds": true,
  "uncapped_counts": true
}
```
