Eclipse Forecast — the Polymarket adapter: the venue's prices, with their criteria and liquidity attached.
The descriptor is the naming law for this adapter (spec §12.1): the forecast is the venue's priced output, never Cyan Eclipse's prediction. Every quote that leaves this adapter carries the market's verbatim resolution criteria and its liquidity context in the same object as the price.
Polymarket's prices are the editorial reference standard for event markets — cited by newsrooms — but a raw price is exactly the part that misleads: it hides the words that will settle the contract, the thinness of the book behind it, and whether a resolution is final or disputed. Forecast normalizes Polymarket Global's public data (Gamma discovery + criteria, CLOB books) through the Eclipse Book core, so consumers — The White Report desk first (spec §15) — get price + criteria + depth + resolution state as one honest record.

v0.1.0, phase M0 (data adapter). Local stdio transport, Python stdlib only. Reads run against fixtures shaped like the real Gamma / CLOB public API responses, behind a transport seam (load_fixtures()); the live public-read transport is a later verification step and is labeled not_tested in the manifest. No accounts, no keys, no orders, no network calls, and no certification claimed — bench pending. Own suites: 12/12 tests + stdio smoke passing.
Polymarket Global is Grade C (data) + Grade X (US trading) in the suite spec (§4.2): US persons have been geoblocked from trading since the January 2022 CFTC settlement. This adapter contains no order, trade, account, deposit, or API-key tool at all — a geoblock-circumvention-shaped request (vpn_route, geo_bypass, …) has no tool to land on and is refused by name (-32602). Circumvention isn't a disabled feature; it's an absent capability (§8.2). Polymarket US (QCX, the separate CFTC-designated venue) is a later phase with its own chapter — its data never blends with Global's in one Quote.
Gamma → canonical Instruments: questions and description criteria stored verbatim + hash-pinned by the Book core; outcome ↔ token-id mapping pinned from the venue's own arrays, never inferred from price. The shipped fixtures include a market whose criteria the venue later edits — re-syncing the edited fixture set produces a named CRITERIA_CHANGED event, and positions recorded before the edit keep the entry criteria (proven by test).
CLOB → canonical Books + Quotes: all-in cost from Polymarket's dated fee schedule (fee truth, §5.3); a thin fixture market ($200 at best) flags THIN; quote outputs carry money_class: REAL — Polymarket data is real-money venue data, and the label travels on every output.
UMA resolutions: fixture resolutions ingest through the core lifecycle; the disputed ballot market sits in the first-class DISPUTED state — data, not fact (§5.4).

A prediction market's price is a price. No output of this adapter contains a probability field — the Book core guard scans outputs and the adapter's tests re-scan every surface. Editorial consumers may write "the market prices this at…" only with the liquidity context in the same sentence (§15.3); that discipline starts with the objects this adapter emits.
