Methodology Version Register

The single source of truth for every publicly released BCI Lab methodology document — one place where every version number, and every “which document currently governs which fact” question, has one unambiguous answer.

This register is the single source of truth mapping every publicly released BCI Lab methodology document to its version number, status, effective date, and relationship to every other document in the corpus. No defined term, threshold, or formula element should be independently redefined, with a different value, in more than one place. Where a document needs to state a version history, a threshold, or a formula, it references this register rather than restating the history itself.

This register does not merge documents or change their editorial independence. The White Paper and BSIP continue to be written, reviewed, and published on their own schedules, for different readers. What this register fixes is a single place where every version number and every “which document currently governs which fact” question has one unambiguous answer.

Scope. This register covers externally published documents only: the White Paper, BSIP (and its predecessor names), the Independence & Conflict Policy, the Public Protocol Annex — including the retired “Institutional Methodology Disclosure” name under which parts of this lineage were previously published — and, as of this update, the ten documents comprising The BCI Protocol governance stack (its index page and nine constituent protocols). Internal working documents — Core Definitions and its amendments, the Sector-Specific Calibration Governance Protocol, the M&A Backtest Registry, and the Action-series working papers — remain out of scope. They continue to version independently, under their own file-based numbering, for internal use.

Rows 11–20 are new in v1.1 of this register. Full detail for this batch is not repeated as ten individual cards — unlike Rows 1–10, all ten share one simple lineage (an unregistered internal working draft, superseded by this Version 1.0), so the differentiated facts worth recording are gathered in one section below instead of restated ten times.

Ten documents entered the register in this update: the index page of The BCI Protocol and its nine constituent protocols (Rows 11–20). Full narrative treatment for this batch is not repeated as ten separate cards — every one of the ten shares the same simple lineage, an unregistered internal working draft superseded by this Version 1.0 — but three facts are differentiated enough to record here rather than leave for a reader to discover independently.

Each of the nine protocols carries its own Institutional Footer, Known Limitations section, and Citation Standard. This register tracks version, status, and lineage only; each protocol's own page remains the authoritative source for its substantive content.

Gaps are marked, not filled. Rows 1–3's exact release dates and the White Paper's v1.0/v2.0 dates (Row 8) are not reconstructed here. They should be filled in from BCI Lab's internal records before this register is treated as complete, rather than estimated for the sake of a tidy table — the same standard this project applies to every other unverifiable historical claim.

“BSIP” is the sole active name going forward. Effective with v4.0, “Institutional Methodology Disclosure” is retired as an active document title. Both of its archived versions (Rows 1 and 5) are preserved here for historical reference only and are not authoritative for current operations. Any page, report footer, or piece of metadata still citing “BSIP v3.0” or “Institutional Methodology Disclosure” should be updated to cite BSIP v4.0.

This register is updated at every future version change to the White Paper or BSIP, and at every future expansion of its scope to a new document family — as this update does for The BCI Protocol. It is the authoritative cross-reference and should be consulted before restating version history in a report, footer, or page metadata, rather than each surface maintaining its own copy of that history.
