Fix inputs and return computation resultsC0 / Evidence Pack (canonical JSON) is the delivery format

Examples C0 can cover

Time-related cases, heat dissipation, materials/manufacturing, energy conversion including electrolysis and CO2 conversion, thrust-to-pressure ratios, and structural health are examples of themes that can be considered when they can be framed as fixed-input, single-point readouts within the C0 bridge family. These are entry examples, not a list of already implemented services. Acceptance and additions are decided case by case.

Current public example

The fixed public example shown now is clock drift / time sync. That does not redefine all of C0 as a time-only service.

What C0 is

C0 is the lane that fixes inputs measurable by existing science and returns a single-point result through SCU's non-public formulas. What is fixed is the input condition and the return format, not disclosure of the formulas or a guarantee of the result itself. What you receive is an Evidence Pack (canonical JSON).

What bridge family means

A bridge family is a common frame that connects the input side defined by existing science with SCU's internal computation side across multiple themes. If different domains share the same return shape, fix the inputs and return one local result, they can sit in the same C0 family.

Delivery format

What you receive is an Evidence Pack (returned JSON). The current-phase standard structure has five items: accepted formatted input JSON, fixed_at (UTC), public reference token (opaque ref), evidenceHash, and pack_sha256.

• The standard pack includes the accepted input, fixed time, public reference token, verification digest, and pack-integrity digest.
• The standard pack does not include raw result data, internal formulas, internal-only requestId, or helper packs.
• Acceptance uses the public reference token and evidenceHash first, then uses pack_sha256 to confirm pack integrity.
• Internal keys and internal procedures are not public; verification follows the SCU-issued package and SCU procedure.

What is not disclosed

Internal methods are not disclosed, and implementation fixes the return scope. Even if requested, attached data is not returned unless explicitly permitted.

Internal methods (formulas, implementation, operational procedures) are treated as top‑secret; deliverables are limited to an acceptance‑ready results package.

• Fix return granularity via staged return scopes
• Even if requested, do not return attached data server‑side unless permitted (record the applied result and reason)
• Record request vs. applied differences (reasons) in the Evidence Pack
