* feat(gold): richer Gold Intelligence panel with positioning, returns, drivers
* fix(gold): restore leveragedFunds fields and derive P/S netPct in legacy fallback
Review catch on PR #3034:
1. seed-cot.mjs stopped emitting leveragedFundsLong/Short during the v2
refactor, which would zero out the Leveraged Funds bars in the existing
CotPositioningPanel on the next seed run. Re-read lev_money_* from the
TFF rows and keep the fields on the output (commodity rows don't have
this breakdown, stay at 0).
2. get-gold-intelligence legacy fallback hardcoded producerSwap.netPct to 0,
meaning a pre-v2 COT snapshot rendered a neutral 0% Producer/Swap bar
on deploy until seed-cot reran. Derive netPct from dealerLong/dealerShort
(same formula as the v2 seeder). OI share stays 0 because open_interest
wasn't captured pre-migration; clearly documented now.
Tests: added two regression guards (leveragedFunds preserved for TFF,
commodity rows emit 0 for those fields).
* fix(gold): make enrichment layer monitored and honest about freshness
Review catch on PR #3034:
- seed-commodity-quotes now writes seed-meta:market:gold-extended via
writeExtraKeyWithMeta on every successful run. Partial / failed fetches
skip BOTH the data write and the meta bump, so health correctly reports
STALE_SEED instead of masking a broken Yahoo fetch with a green check.
- Require both gold (core) AND at least one driver/silver before writing,
so a half-successful run doesn't overwrite healthy prior data with a
degraded payload.
- Handler no longer stamps updatedAt with new Date() when the enrichment
key is missing. Emits empty string so the panel's freshness indicator
shows "Updated —" with a dim dot, matching reality — enrichment is
missing, not fresh.
- Health: goldExtended entry in STANDALONE_KEYS + SEED_META (maxStaleMin
30, matching commodity quotes), and seed-health.js advertises the
domain so upstream monitors pick it up.
The panel already gates session/returns/drivers sections on presence, so
legacy panels without the enrichment layer stay fully functional.
