# ASSET SHIFT — FX Free Official Raw Connection Specification v0.1

Fixed: 2026-08-26  
Status: PREREGISTERED CONNECTION ONLY  
Model execution / public FX classification: BLOCKED

## Fixed architecture

Reserve = IMF COFER, Banking = BIS LBS, Debt = BIS IDS. The existing 8-quarter formal direction and 4-quarter Transition Risk remain unchanged. Structural, Base and Market remain separate. No score, threshold or result is changed here.

| Domain | Official source | Frequency | Primary Raw route | Rights |
|---|---|---|---|---|
| Reserve | IMF COFER (`IMF.STA:COFER`) | Quarterly from 1999Q1 | IMF SDMX / official download | Conditional |
| Banking | BIS LBS | Quarterly | Full-topic bulk CSV ZIP | Conditional |
| Debt | BIS IDS (BIS-compiled) | Quarterly | Full-topic bulk CSV ZIP | Conditional |

COFER has a material boundary: the 2025Q3 publication revised history back to 2000Q1 and eliminated the former unallocated portion. No silent pre/post splice is allowed.

## Raw / Vintage contract

Keep exact source bytes, original filename, source URL, UTC retrieval time, dataset/flow identity, latest reference period, release date, schema/DSD version, terms capture date and SHA-256. Storage is append-only; earlier Vintages are never overwritten. Schema drift is quarantined and produces `Unknown`.

Only the latest completed quarter shared by all three accepted datasets may enter a later run. Partial quarters, interpolation, carry-forward, proxy substitution, mixed Vintages and methodology splicing are prohibited.

## Rights disposition

IMF statistical-data terms allow reuse with attribution and transformation disclosure, but direct potential commercial reuse to `copyright@imf.org`; third-party material is excluded. BIS use is unrestricted only under its listed conditions, including attribution, non-misleading use and no additional subscriber charge caused by inclusion in a commercial product. Thus free derived display remains conditional and commercial display is blocked pending written IMF disposition and BIS pricing-model review.

## Release gate

Exact official series keys, one untouched Raw Vintage per source, schema-only Cold Start, common-quarter coverage, rights disposition, Forward observation and human approval are required. This document authorizes no result calculation or FX classification.
