# Validation Proof Slot — H-POC-VALIDATE

When the **Dynamic Update Proof Loop** completes, this directory holds the proof that returned **into** the sealed bundle — so assessors receive context, update record, and confirmation in one offline-verifiable package.

**Provenance brief (scenarios, dynamism, significance):** [`../../executive-summaries/Dynamic_Update_Provenance_Brief.md`](../../executive-summaries/Dynamic_Update_Provenance_Brief.md)

## Expected files (when loop runs)

| File | Produced by | What it proves |
|------|-------------|----------------|
| `context-anchor-descriptor.json` | Cryptographic Context Anchor | Which sealed context authorized the update |
| `model-update-pathway-run.json` | Model Update Apply | Before/after state, authorizer, execution audit |
| `dynamic-update-proof.json` | Dynamic Update Proof Loop | Aggregate proof that the loop closed |
| `sole-signatory-confirmation.json` | Sole Signatory Confirm | Policy validation (human acceptance criteria) |

## Current status

**Design encoded; loop not executed.** Hypothesis **H-POC-VALIDATE** remains `design_pending`.

Sole signatory policy: [`../../collaboration-pathways/meta/bundle-validation-policy.v1.yaml`](../../collaboration-pathways/meta/bundle-validation-policy.v1.yaml) — **Tricia Wang** (mutable only via recorded PathwayRun).

## After proof is written

Re-seal the bundle so new files enter the content manifest:

```bash
python3 tools/collaboration-bundle/sign_bundle.py sign collaboration/20260602-160000
python3 tools/collaboration-bundle/sign_bundle.py verify collaboration/20260602-160000
```

Success of H-POC-VALIDATE demonstrates that this collaboration-bundle format can serve as a **cryptographic context anchor** for dynamic model updates — a proposed extension to PoC Provenance, not part of AAIS v0.1.0 unless adopted.
