Goal

Replace the seed data product catalog with real TFGrid node listings from hero_ledger. The dev gateway already has 6 compute node listings with real resource specs and pricing.

Depends on

mycelium_code/home#50 (hero_ledger integration — wallet done)
lhumina_code/hero_ledger#41 (generic listing type — for non-compute categories)

What works today

marketplace.listListings returns real TFGrid v3 nodes:

{"listing_id": 3, "node_id": 82, "country": "United States",
 "total_resources": {"cru": 8, "mru": 33541128192, "sru": 500107862016},
 "available_slices": 2, "pricing": {"on_demand_hourly": 1}}

No authentication needed — call_public method.

Tasks

P1 Create src/services/impl_ledger/product_catalog.rs implementing ProductCatalog trait
P2 Map hero_ledger listing fields to marketplace Product model
P3 Wire into ServiceProvider (when APP_WALLET_BACKEND=ledger, use ledger catalog for compute)
P4 Fallback: non-compute categories still read from OSIS until generic listing type is ready
P5 Add ledger integration test (tests/ledger_integration.sh) — verify real listings appear
P6 Deploy to dev with ledger mode, verify SPA shows real TFGrid nodes

Live and working — real TFGrid nodes in marketplace

Deployed with APP_WALLET_BACKEND=ledger on dev. The marketplace now displays real TFGrid v3 node listings from hero_ledger:

ledger_3: TFGrid Node 82 — 8 vCPU, 31GB RAM [compute] 1.0 USDH/hr (US)
ledger_4: TFGrid Node 390 — 4 vCPU, 8GB RAM [compute] 1.0 USDH/hr (Belgium)
ledger_5: TFGrid Node 391 — 4 vCPU, 8GB RAM [compute] 1.0 USDH/hr (Belgium)

6 real listings from marketplace.listListings (public method, no auth).

Done

P1: LedgerProductCatalog implemented
P2: Listing JSON → Product model mapping (CPU, RAM, SSD, country, slices, pricing)
P3: Wired into ServiceProvider (ledger mode uses LedgerProductCatalog)
P4: Non-compute categories fall back to OSIS
P6: Deployed to dev, verified real nodes show up

Remaining

P5: Ledger integration test suite
