# THE POUR provenance record

- Record date: 2026-07-29
- Public object: Prism Glass optical instrument
- Canonical routes: `lab-gallery.html`, `prism-glass-lab.html`
- Admission authority: owner-approved recovery on 2026-07-29
- Runtime boundary: browser prototype only; no CaitOS state, tools, profiles,
  memories, beliefs, actor identity, or endpoints

## Owner-approved recovered module

The owner explicitly admitted the Discordia-authored, reference-derived prism
module from deployed evidence into the canonical public site for the landing
threshold and prism-only exhibition on 2026-07-29. This admission records
provenance; it does not retroactively establish a permissive license for the
upstream Hugging Face Space.

- Canonical module: `_ds/bw-paper/prism-glass.js`
- Deployed-evidence source: `_ds/bw-paper/prism-glass.js` inside the read-only
  `iamcait-alpha-site-bw` deployed snapshot held in owner-local storage
- Source and canonical SHA-256:
  `a96e117d9d37ca987f563f5fccfd7b28b75b8386c818ad5eee3c130f6d6f5458`
- Three.js import: exact `0.170.0` pin
- Truth label: decorative optical/browser instrument; never sha256man
  computation, interpretation authority, or live cognition/runtime state

## Upstream reference boundary

- Reference URL: `https://huggingface.co/spaces/webml-community/bonsai-webgpu-kernels`
- Reference revision observed through public Space metadata on 2026-07-29:
  `baf1a20b9fc7e12da1787764ede3abd5760ff188`
- Accessed: 2026-07-29
- License status at access: no license metadata or license file was established
  for the Space source; link/reference is not permission
- Use in recovered module: reference-derived optical composition and technique,
  as documented in the module header
- License claim: none. The source is linked and attributed; this record does not
  claim the Space source was permissively licensed or copied under an upstream
  license grant.

## Prior deployed-evidence receipt

The deployed evidence snapshot remains read-only in owner-local storage as
`iamcait-alpha-site-bw`. The hash below is the
receipt used to verify that recovery into canonical source was byte-for-byte.

- `_ds/bw-paper/prism-glass.js` SHA-256:
  `a96e117d9d37ca987f563f5fccfd7b28b75b8386c818ad5eee3c130f6d6f5458`
- `prism-glass-lab.html` SHA-256:
  `a74b1b92f041765947db3f607c92929f5c013efcf271825cd59ff2d66113bb06`

## Receipt Reliquary clean-room boundary remains separate

- `assets/receipt-reliquary.js` remains a separate clean-room Canvas 2D study;
  it is not mounted or listed by the public prism-only gallery.
- Rendering: Canvas 2D, not Three.js shader code
- Geometry: five unequal quadrilateral sealed planes plus central elliptical
  absence; never an equilateral triangular prism
- Motion: small packet-independent viewpoint drift, disabled under
  `prefers-reduced-motion`
- Interaction: pointer/keyboard witness viewpoint plus explicit reseal
- Packet mapping: SHA-256 bytes drive tilt, density, scars, and witness marks;
  no calculator math occurs in rendering code
- Truth label: visual seed hash / toy, never calculator receipt

## Historical clean-room hashes from initial reconciliation

- `assets/receipt-reliquary.js`:
  `b6235bde55f7ce621e6c6e8605242fe8ec8320628bb4fe58dcdabf4e4f6e12da`
- The original Receipt Reliquary page hashes are retained in repository history
  as reconciliation evidence; they are not current prism route hashes.
