What building it taught us

The connector's own docstring, verbatim. It lives beside the code so it cannot drift from it.

Spanish INE CPI from complete, immutable bilingual source cohorts.

Source responses stay byte-for-byte intact. A generated, value-free manifest freezes vocabulary and source membership for replay and selects one complete resource owner per native series after checking every overlapping value.
