Spin-off dislocation — SEC Form 10 lineage protocol

By , Canli Capital

Declared: 2026-08-16 before downloading any SEC full index for this protocol.
Stage: official-source lineage only. Prices, returns, event outcomes, and performance are forbidden. Zero return hypotheses are spent.

Locked question

Can the complete 2016–2025 exchange-registration candidate universe be reconstructed from official quarterly EDGAR full indexes without starting from a modern ticker list or known successful spin-offs?

Frozen source and population

  • Download all 40 SEC master.idx files for 2016 Q1 through 2025 Q4.
  • Hash-bind raw bytes and preserve URL, year, quarter, byte count, row count, and parse status.
  • Retain form type exactly 10-12B or 10-12B/A.
  • An initial candidate is form 10-12B; amendments remain lineage but never create new events.
  • Preserve CIK, company name as filed, filing date, archive filename, accession, form, and source quarter. Do not join to current tickers, prices, corporate-action outcomes, or commercial event lists.

Form 10 registrations are not presumed to be spin-offs. This stage discovers candidates only.

Locked gates

All are required for PASS_TO_DOCUMENT_SCHEMA_AUDIT:

  1. Exactly 40 quarter indexes download and parse with immutable SHA-256 hashes.
  2. Every retained archive filename yields a canonical SEC accession.
  3. Filing identity (CIK, accession) is unique after exact-row deduplication.
  4. Every year contains at least one initial 10-12B, and the ten-year initial population contains at least 50 rows. These are source-usefulness gates, not alpha gates.
  5. No prices or returns are opened and no return hypothesis is spent.

Failure is SOURCE_LINEAGE_REQUIRED or DATA_GATED; thresholds are not revised after aggregate counts are observed.

Required next stage after a pass

A new locked document-schema audit must obtain acceptance timestamps and immutable primary documents, distinguish genuine pro-rata separations from other registrations, map parent and child, and extract distribution ratio, record/distribution dates, amendment state, cancellation, when-issued status, fractional-share handling, and tax-basis references. It must use a frozen blind accuracy set before any prices are opened.

Only after that stage passes may a return preregistration define instrument identity, parent/child legs, entry clock, auction and when-issued execution, corporate actions, costs, borrow, capacity, holdouts, trial accounting, DSR/PBO, perturbations, and diversification gates.
