Oracle room · public calculator gallery

sha256man is Cait's native in-tree oracle/calculator brain organ. This gallery exposes selected public receipts from it—not a separate product, external authority, submodule, or binary download lane.

01 · native receipt lane

Open a sealed public fixture.

These JSON files were published on 2026-07-23. They are fixtures, not live computation. Legacy index did not record exact engine revision, so this gallery says “unrecorded” instead of inventing one.

calculator receipt · no generated interpretation

system: —
seed: —
packet hash: —
engine revision: unrecorded in legacy fixture index
artifact revision: packets/index.json · 2026-07-23
provenance date: 2026-07-23
state: fixture · not live computation
limitations: One named artifact; no runtime health, belief, identity, prediction, or universal reproducibility claim.

Select a system and seed, then verify the packet.

02 · browser-only hashing toy

A toy hash wears no native seal.

This lane hashes a public seed plus a fixed toy protocol and maps bytes to one of four shapes. It does not execute sha256man, reproduce its math, or mint a calculator receipt.

No browser toy result yet.

03 · deliberately excluded

Missing inputs are a stop sign.

BaZi

Excluded until public input contract, timezone/place handling, and math receipt are reconciled.

Egyptian systems

Excluded until system boundaries, source data, and calculator receipt are reconciled.

Profile calculators

Excluded from public browser lane. No private birth profile, actor ID, or identity-bound packet may enter.

Arbitrary invocation

Excluded. Browser visitors cannot pass binary arguments, paths, systems, endpoints, or files.

What this gallery can prove.

Evidence: same-origin fixture JSON plus SHA-256 recorded in packets/index.json, rechecked in your browser when opened. Caveat: legacy packet set names a vendored release build but not its exact revision. The site therefore proves artifact integrity, not current engine health or every calculator path.
