Two additions for stable-URL access to rotating versioned parquets: 1. Worker alias route: GET /current/<flavor>.parquet reads current/manifest.json from R2 and 302-redirects to the dated file it points to. Redirect response carries short 5-min Cache-Control so rotation propagates quickly; the target (versioned file) keeps its immutable 1-year cache. DuckDB-WASM / curl / browsers all follow 302s transparently, so range requests hit the target directly. 2. scripts/enrich_wide_with_oc_thumbnails.py: DuckDB LEFT-JOIN script that takes the unified Zenodo wide parquet (thumbnail_url all NULL, see isamplesorg#131) and Eric Kansa's oc_isamples_pqg.parquet (48K thumbnails) and produces an enriched wide file with ~47.7K thumbnails populated for MaterialSampleRecord pids that overlap both. Used today to build and ship isamples_202604_wide.parquet via https://data.isamples.org/current/wide.parquet. The older isamples_202601_wide.parquet stays in place, untouched, still immutable. Verified via DuckDB query through the /current/ URL: 47,717 rows with thumbnail_url populated. Closes the "soft-link" piece of isamplesorg#131. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Follow-up to #131. Adds
/current/<flavor>.parquetWorker redirects for stable URLs that point at rotating dated files, and the DuckDB enrichment script used to buildisamples_202604_wide.parquet(47,717 thumbnails recovered from Eric's OC PQG).isamples_202601_wide.parquetstays untouched./current/wide.parquetnow serves the enriched file.Verified live:
duckdbquery through/current/wide.parquetreturns 47,717 rows with populated thumbnails.
