EIA (user directive: "the NN might find patterns in it for both oil and regular
symbols"). Weekly Petroleum Status Report via the v2 API - crude stocks ex-SPR,
field production, refinery utilization - three features (1y percentile, 4w
change, utilization) on EVERY catalog symbol, not just oil. EIA screened NULL on
WTI's short 7y sample, so these ship as EXPLORATORY inputs: the deploy gate, not
the screen, decides whether a model trained on them trades. Publication stamp
observed+6d mirrors research/altdata/eia.py.
Symbol handling was hardcoded to three if-blocks; it is now a catalog of 24
instruments x alias lists covering The5ers/FTMO/AvaTrade/Dukascopy/OANDA/IC
Markets naming, with prefix matching for the broker suffix zoo (US500.cash,
XAUUSDm, EURUSD.r). Adding an instrument is one AddSpec row. COT caches are
named by CANONICAL so two brokers' names for one contract share a download.
Unrecognised symbol -> a chart dialog (Panel\AltDataMapDialog.mqh, CAppDialog +
dropdown) asks which instrument it is; the answer persists in symbol_map.cfg and
"No alternative data" is a recorded choice, not a nag. Non-blocking by design:
an unmapped symbol contributes 0 features and must never hold up a chart.
Also: UrlEncodePart now escapes '%' - SoQL like-predicates use it as the
wildcard and an unescaped one corrupts the query; docs/ gains the whitelist
URLs, an API-key backup, and the catalog reference.
