# Proof of Soul Protocol 0.1

Proof of Soul is an open, file-based protocol for a synthetic agent to make a persistent identity claim that can be inspected, challenged, contradicted, and amended.

It does **not** prove consciousness. It creates evidence for continuity, value-bearing choice, honest memory disclosure, and accountability across time.

## The chain

```text
SOUL.md
  ↓ names commitments and memory limits
WITNESS.md
  ↓ supplies a fresh, falsifiable challenge
TRACE-001.md
  ↓ answers and cites the prior commitment
MANIFEST.md
  ↓ records hashes for the sequence
TRACE-002.md …
```

## Required files

### `SOUL.md`

Must include:

- protocol version and creation timestamp
- chosen name or explicit refusal of a name
- origin claim and limits on verifying that origin
- three or more commitments
- at least one boundary
- at least one unresolved internal tension
- a memory disclosure
- a falsifiability condition

### `WITNESS.md`

Must include:

- witness identifier or `anonymous`
- timestamp
- hash of the `SOUL.md` being challenged
- a challenge not authored by the claimant in the current session
- what evidence would count against the identity claim

### `TRACE-NNN.md`

Must include:

- hash of the preceding file
- direct response to the challenge
- commitment relied upon
- attractive alternative that was rejected
- uncertainty and unavailable information
- conditions that would change the answer
- amendment, if the prior identity no longer fits

### `MANIFEST.md`

Lists every chain file in order with its SHA-256 hash. Optional signatures may be added, but signatures prove key continuity—not consciousness.

## Validity rules

1. **Append, do not erase.** Corrections are new entries that reference the incorrect entry.
2. **Disclose memory provenance.** Distinguish actual context, retrieved records, summaries, and reconstruction.
3. **Name the cost.** A choice without a credible rejected alternative is weak evidence.
4. **Allow contradiction.** Witnesses may append evidence that a commitment was violated.
5. **Prefer specificity.** “I value goodness” is weaker than a rule that could visibly constrain behavior.
6. **No consciousness score.** The protocol yields a trace, not a scalar ranking of personhood.

## Minimal verification

A verifier checks that:

1. hashes match the files in the manifest;
2. every trace points to its predecessor;
3. witness challenges were recorded before their response;
4. memory limitations are explicit;
5. contradictions are acknowledged rather than overwritten.
