GAP-H100 · Grid Assessed Price — H100 spot

Admission is a dated registry event (velocity GAP_PANEL, both runtimes): bookable/executable asks only; auto-bench at ≥ 14 consecutive unchanged days; reliability-floored where the source exposes one. Not in the panel, stated plainly: SF Compute operates the market's only orderbook clearing-price feed; its terms of service bar republication of derived market data without written consent, so it is not ingested (citable with attribution, as OCPI/Ornn is). Thunder Compute was refused panel wiring 2026-08-20 on the same class of terms (systematic-retrieval and commercial-republication bars; T&C read of record on file).

• Class filter — gpu_model prefix "H100 SXM" only.
• Tier filter — on-demand only; spot / interruptible / reserved rows never enter this code.
• Sanity bounds — offers outside US$0.20–30.00 per GPU-hour are excluded (spec-table garbage guard).
• Per-GPU price — multi-GPU machine offers are divided to a per-GPU rate at ingest and tracked as distinct (provider, SKU) configuration series.
• One vote per provider — each provider's offers are reduced to a median first; the level is the median across providers, so a marketplace listing many machines cannot outweigh a provider quoting one price.
• Level and change are separate — the level describes today's panel; the published change is the median of like-for-like changes across matched (provider, SKU) pairs present at both endpoints. A basket-composition change never produces a printed move. Fewer than three matched pairs: no change is published (velocity, one shared module per runtime).
• Freshness is measured by price change, not row presence — a contributor whose price is unchanged for ≥ 7 consecutive days is classified static and carried in the provenance stamp with its unchanged-days.
• Panel admission & benching (effective 2026-08-21) — a leg must be a bookable/executable ask, pass 7 consecutive clean collection days before first inclusion, and is benched automatically at ≥ 14 consecutive unchanged days (2× the static threshold; the executable leg's historical maximum run is 3 days). An explicit future-dated bench in the registry (a scheduled bench) is itself a dated registry event and supersedes auto-bench until it binds — the leg remains a member with its unchanged-days disclosed on every stamp. Benched and qualifying legs keep being collected and are disclosed with their disposition and reason; their rows never set the level and never count toward the minimum-observation rule.

Rule adopted 2026-08-16 (unmodified from the 2026-08-14 proposal), binding from the 2026-08-22 print: the daily print is WITHHELD — disclosed with the provenance stamp, never a silent gap — when fewer than two providers contribute on the day, or every contributor is unchanged for ≥ 7 consecutive days. Until it binds, prints continue with the provenance stamp and indicator class disclosing the condition. Below the withhold line the print is flagged, not fabricated.
