Plan 1 / C0

Monthly path (C0 / Evidence Pack delivery)

This page covers terms, reference pricing, and next steps when Plan 1 becomes a candidate after eligibility review. Use `/c0` as the authority for the meaning and return boundary of C0; this page handles only transaction style and process conditions.

Plan 1 / C0 / Sealed Bid / Buyout

  • Monthly capacity (per availability calendar)
  • Method: sealed bid or buyout
  • Deliverable: Evidence Pack (canonical JSON)

C0 framework details at /c0.

Pricing includes capacity, fixing the I/O specification, generating the Evidence Pack, acceptance readiness, and confidentiality operations.

✓ Fit check
  • You can fix objectives/constraints/conditions in writing (inputs can be defined).
  • Acceptance criteria can be decided in advance.
  • Outputs can be delivered as KPIs / summary / comparative metrics.

Not a fit: substituting the experiment itself / inputs cannot be defined / acceptance criteria cannot be set.

The specific target is finalized after eligibility confirmation.

Good fit examples

The following are general examples and are not intended as naming, endorsement, involvement, or implied track record for any specific organization or individual. Suitability is determined case-by-case after eligibility confirmation.

  • Operators with a monthly decision cycle (regular KPI/log submissions).
  • Organizations expecting third-party submission/audit (want a fixed acceptance record using a public reference, `evidenceHash`, and `pack_sha256`).
  • You need one deliverable per case ID (rather than sweeps or bulk comparisons).
  • You must keep internal methods undisclosed and only fix acceptance criteria and evidence.

Pricing assumptions & revision rules

Prices are revised annually (base year 2025). Blank/non-numeric annual rates are treated as the same as the previous year. Final terms are fixed by individual contract.

Reference pricing includes: monthly capacity (defined by the availability calendar), fixing I/O spec, generating the Evidence Pack (audit trail) and acceptance readiness (verification info/procedure), and confidentiality operations.

Operating Model

Intake: monthly (capacity defined by the availability calendar)

Bid window: day 2 00:00 to month-end 23:59 (JST)

Submit via bid form (sealed bid)

Tally & notify: day 1 00:00–23:59 (JST)

Notify highest bid of previous month

Tie at top bid: first-come tie-break

Submission reaching our servers first is prioritized (announced if changed)

Eligibility: primarily B2B

Companies, research institutions, public institutions. Verification and usage limits are fixed by contract.

External delivery: one result set per engagement ID

No comparisons/sweeps

Example: Jan bid window (Jan 2–Jan 31) → tally & notify on Feb 1 (JST)

Execution flow (individual contract)

Phase 1: Contract

  1. Winner notification (day 1 each month)
  2. Execute contract → invoice deposit (30% of bid) → accept after payment confirmation.

Phase 2: Execution

  1. Submit input package (within 30 days after deposit confirmation)
  2. Validate input → lock-in notice (no changes afterward)
  3. Compute in private environment (re-run as needed)
  4. Provide Evidence Pack via access-controlled, time-limited URL

Phase 3: Acceptance

  1. Acceptance: if no notice is received within 14 days after delivery, it is deemed received (use `opaque_ref + evidenceHash` as the primary verification pair and confirm pack integrity with `pack_sha256` when needed; terms can be adjusted by contract).
  2. Invoice remaining balance (70%) → payment
  3. Delete data per retention policy

Delivery timeline (estimate): ~30 days from input lock-in (varies by engagement; contract terms prevail if separately agreed).

Bank details are stated on the invoice.

Deliverable

The core deliverable is an Evidence Pack (canonical JSON). It includes integrity verification and summary information required for acceptance.

Standard structure (TOC-level example)

  • Metadata (identifiers/protocol version, etc.)
  • Input conditions record (including hashes for reproducibility)
  • Computation results (KPIs/summary tables, etc.)
  • Integrity metrics (SHA-256)
  • Acceptance criteria compliance record and acceptance procedure

Internal key names and detailed procedures are not disclosed publicly.

  • Document integrity decision criteria (iterations/conditions, etc.)
  • Tolerance can be fixed by individual contract.
  • If a No-Go (no external delivery) condition applies, record the reason in the Evidence Pack.

Data Handling

We separate retention of work data (inputs/attachments/intermediates) from the Evidence Pack (audit trail) and fix it via retention policy.

Next step

Check the C0 guide for the return boundary, and if needed review the fixed demo for acceptance behavior before submitting your bid.

Standard Track

If you can accept publication of usage records and anti-exploration conditions, consider the Standard Track for the normal price range under public-use conditions. No slot limit. Current-year reference pricing is governed by /pricing with annual revision support.
