The AMECO vintage catalogue becomes data in its own right
catalogues the vintages displayed by the European Commission’s official AMECO archive since 2011. The goal is not to accumulate dates: it is to identify which structural-balance estimate was actually available when a fiscal decision was made and then compare it with later revisions.
Why this step is necessary
One metadata anomaly is preserved as-is: the archive page currently displays “3 June 2025” next to an entry labelled “AMECO - Autumn 2025”. Delta-Sierra does not silently correct this contradiction; the date is flagged for source-file verification.
2. Import the source package
Compute the SHA-256 fingerprint before extraction.
3. Extract only FRA + UBLGAPS
The parser stops if the target series cannot be identified unambiguously.
4. Preserve two time perspectives
The real-time value and the ex-post revised value remain separate fields.

The public catalogue contains vintage metadata, not annual observations until source packages have been imported and hashed.
