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 update records a two-document amendment dated September 20, 2026. The Independence & Conflict of Interest Policy moves to v1.3 and the Legal Disclaimer & Risk Governance Framework to v1.1, with their predecessors (Rows 22 and 24) marked Superseded.
Unlike the September 10 release, this is not a correction of drift. It is a deliberate change to a public commitment. Policy v1.2 stated that BCI Lab's sole commercial model was research access purchased by buy-side parties, and Section I of that Policy said that changing this would require a public amendment recorded here. Policy v1.3 adds a second, narrowly defined arrangement, the Self-Assessment Engagement, and states the safeguards that fence it from every public reading. Legal Disclaimer v1.1 conforms the one section of that document that described the same commitment in narrower terms. Documents that summarize the earlier wording have not yet been conformed; see Notes on This Register.

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 methodology and governance documents: the White Paper, BSIP (and its predecessor names, including the retired “Institutional Methodology Disclosure” title), the BCI Lab Institutional Charter, the Independence & Conflict of Interest Policy, the Public Protocol Annex, the Legal Disclaimer & Risk Governance Framework, and the ten documents comprising The BCI Protocol governance stack.
Deliberately out of scope. Two documents revised in the September 10 cycle are not tracked here: the Terms of Service and the Privacy Policy. Both govern use of this website and the handling of visitor data rather than the methodology itself, and neither makes a methodological representation. They are version-controlled on their own pages. This exclusion is recorded rather than left implicit, so their absence is read as a scope decision and not an omission. 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 — likewise remain out of scope and version independently for internal use.

Rows 21–24 entered at v1.2; Rows 25–26 are new in v1.3 of this register. Rows 22 and 24 move from Current to Superseded in the same update; their cards are preserved below rather than replaced, since a superseded version remains the governing reference for any report published under it.
Ten documents entered the register at v1.1: the index page of The BCI Protocol and its nine constituent protocols. 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.
Protocol numbering in this stack runs continuously from BCI-FIN-2026-003 through BCI-GOV-2026-012. BCI-*-2026-010 is reserved for an internal document — covering weighting coefficients and risk-factor detail — never intended for external publication. The gap is recorded here, not filled, consistent with how this register already treats the “v3.0” gap in Row 6.
| Protocol ID | Name | Predecessor | Notes |
|---|---|---|---|
| — | The BCI Protocol (index) | — new | Groups the nine protocols into Evidentiary Discipline, Calibration & Data Governance, Application, and Institutional Legitimacy. |
| FIN-2026-003 | Capital Loading Stress Standards | Working draft, Jan 17, 2026 | Rediscovered alongside FIN-2026-004 after the rest of the stack was already underway. Removed a Decision Binding Interface-pattern conflict with its own §04. |
| FIN-2026-004 | Decentralized Interpretation Protocol | Working draft, Jan 17, 2026 | Rediscovered alongside FIN-2026-003. Replaced an undefined term (“BCI Premium Stability”) with the Premium Quality Grade framework already defined in FIN-2026-009. |
| MOD-2026-005 | Structural Blind-spot Backtesting Protocol | Working draft, undated | First protocol in the stack to reach the register. |
| MOD-2026-006 | Structural Failure Mode Monitoring Protocol | Working draft, undated | Renamed one failure mode (Systemic Parasitism → Systemic Extraction Cascade) and removed a “Forecast statement” mechanism that conflicted with BSIP v4.0 §6. |
| MOD-2026-007 | Algorithmic Autonomy Protocol | Working draft, undated | — |
| TEC-2026-008 | Data Provenance & Sensor Protocol | Working draft, Jan 2026 | Carried the retired “Brand Climate Index” name; see disclosure below. |
| FIN-2026-009 | Balance Sheet Integration Manual | Working draft, Jan 17, 2026 | Carried the retired name; see disclosure below. Most substantially revised document in the stack, alongside MOD-2026-006. |
| GOV-2026-011 | Trust Origination & Epistemic Legitimacy | Part I of a combined working draft | Split from one draft into two independently addressable protocols (011–012). |
| GOV-2026-012 | Misuse Prevention & Interpretive Safeguards | Part II of the same draft | Split counterpart to GOV-2026-011. |
Earlier updates to this register recorded first registrations and corrections: language that had drifted out of step with the document above it. Rows 25 and 26 are different in kind. Independence & Conflict of Interest Policy v1.3 narrows a commitment that v1.2 stated without qualification, and does so by decision. The reason is recorded in the Policy's Version Note and repeated here so that it is not left to be inferred: a structural diagnostic is most useful to the people accountable for the brand it describes, and BCI Lab now offers it to them on a confidential, fixed-fee basis, fenced from all public research.
The change is recorded as a change. Nothing in Row 25 is presented as a clarification, and the v1.2 statement it replaces remains preserved at Row 22.
Three published documents summarize the earlier commercial model and have not yet been conformed to Policy v1.3: BSIP v4.0 §7.2 and its Independence footer line; White Paper v4.0, Section V (Independence); and the About page's statement that BCI Lab does not accept compensation from the entities it evaluates. Each will be conformed at its next revision, and each conformance will be entered here.
Until then, Independence Policy v1.3 governs the commercial-model commitment, as its opening paragraph provides, and where those documents describe it more narrowly, Policy v1.3 is the reference. This register records the gap rather than leaving it to be found.
Core Definitions v1.0 recorded the retired “Brand Climate Index” name as appearing in exactly one place: the Hermès scorecard copyright notice. Preparing the v1.1 update surfaced two further instances, in the January 2026 working drafts of BCI-TEC-2026-008 and BCI-FIN-2026-009, and the count was corrected from one to three.
Preparing the v1.2 update surfaced two more: the unregistered Charter draft superseded at Row 23, and the previously published institutional overview page. The count of confirmed historical instances is corrected here from three to five. Each was removed at the point it was found. That this count has now been revised upward twice is itself the record: a retired name does not disappear on the day it is retired, and the only way to know how far it spread is to keep counting in public.
Rows 23 and 24 each supersede a document that existed, circulated internally, and carried a version label, but was never formally reviewed or entered in this register. One carried two different version numbers within the same text; the other was labeled v2.0 with no registered v1.0 behind it. This is the same failure pattern recorded at Row 6, where a version label circulated in public metadata with no approved document behind it, and at Rows 11–20, where ten protocols existed only as unregistered drafts. The pattern is recorded rather than tidied away: a version number carries no authority until the document behind it has been reviewed and registered here.
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.
The Institutional Methodology Disclosure v2.0 update (Row 5) is the one place in the record where the Decision Binding Interface and the confidence-band DRG mechanism are both traceable to a single event: an April 2026 update that explicitly aligned itself to draft “BSIP v3.0” content that was never itself finalized or formally approved. This is not two unrelated bugs found separately — it is one update whose source material didn't clear governance before being built on. The two further confidence-band references corrected at Rows 21 and 22 trace to the same origin.
“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.
When this register is updated. At every version change to any document within its scope, and at every expansion of that scope to a new document family. The v1.1 update tested the second trigger for the first time; the v1.2 update was the first to test the first, with four documents revised or first registered without any change to the White Paper or BSIP; the v1.3 update is the first to record a deliberate amendment to a public commitment rather than a correction. 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.
