This page is the entry point for WorldMonitor’s China data. It describes the launched and explicitly blocked source contracts; it is not a claim that every upstream source is healthy at this moment. Current transport and content health remain visible through the China projection in /api/health. /api/seed-health reports whether the China coverage evaluator itself ran recently; a fresh evaluator heartbeat does not prove healthy China content.

Coverage inventory

Health projection registry

The China health projection tracks these stable contracts. launched means the lane is admitted to the China projection; it does not override the lane’s live freshness or content status. JODI remains available to existing global energy products. Its China oil and gas contracts stay blocked because the reviewed upstream country index does not currently publish substantive CN rows. A healthy global JODI heartbeat therefore cannot be presented as China coverage. Detailed method and source contracts:

​
Status and missingness

Source arrival is not the same as usable content. China health evaluates transport freshness and content freshness separately. A successful request can still publish stale, partial, empty, or timestamp-unknown content. The public contracts use explicit states:
  • available or healthy means the required payload passed its domain validation and freshness rules;
  • partial or degraded means some reviewed coverage is missing, stale, or invalid while other evidence remains usable;
  • stale means the last valid observation is outside its content budget;
  • unavailable means no usable observation can be published; and
  • blocked means a source was deliberately not launched, normally because robots, terms, transport, or source-substance review did not pass.
Missing categories are never converted to zero, normal, unchanged, or current. Last-good preservation keeps its original observation time and reports the current transport failure.

Bilateral HS4 import baskets

The bilateral store covers the 20 reviewed bilateralHs4Code entries in scripts/shared/comtrade-strategic-products.json. Each country shard contains annual imports by HS4 product and the leading exporter partners. It supports country exposure, route impact, multi-sector shock, and the PRO get-country-products route. Detailed bilateral rows are not part of the anonymous China summary. The authenticated Comtrade route sends one four-year period window, Y-2 through Y-5, for each of the two HS4 batches. The normalizer keeps the newest year per product-and-partner pair, so a response cannot silently mix annual values. When COMTRADE_API_KEYS is absent, the public preview route cannot accept a period list and instead tries Y-2 followed by Y-3. The scheduled production contract is deliberately quota-bound: A run below the 110-shard floor writes partial seed metadata rather than claiming full success. Failed reporters preserve an existing shard for at most two consecutive runs; after that, the shard may expire so the on-demand public fallback can probe it again. Rate limits, quota exhaustion, and request-budget exhaustion publish partial coverage and stop the run instead of overwriting last-good country data with empty payloads.

Access boundaries

  • Country summary, corridor conditions, decision-signal summaries, provenance, and aggregate health are available through bounded public surfaces.
  • Detailed corridor control towers and activity-nowcast evidence are REST/UI surfaces. MCP does not expose dedicated tools for either route; Pro MCP receives their bounded summaries through get_china_decision_signals.
  • Pro MCP reads the canonical macro and release-calendar caches through get_economic_data with dataset china-macro or china-release-calendar.
  • Detailed bilateral HS4 product rows and route exposure are PRO-only.
  • The Pro MCP decision-signal tool receives the same bounded items and provenance as the public composition, not raw exchange documents or unrestricted source expansion.
  • Proxy credentials, raw per-attempt request diagnostics, cache names, and detailed freshness thresholds remain operator-only. Public documentation names the configuration keys and selection semantics, not their values.
No China surface should be interpreted as independent verification merely because its publisher is official. Publisher identity, extraction confidence, classification confidence, corroboration, and freshness remain separate claims.
