WorldMonitor maintains two independent official-document lanes: revision-aware numeric macro observations and typed policy/enforcement events. They share the decision-signal provenance contract, but they do not share fetchers, scoring, or freshness rules.

​
Official macro observations

The launched macro snapshot requires five series: NBS is collected from www.stats.gov.cn/english/PressRelease/; SAFE is collected from www.safe.gov.cn/safe/. Both sources have bounded request budgets, manual redirect handling, response-size limits, robots preflight, source-host allowlists, and reviewed attribution requirements. The macro seeder does not use a proxy to bypass a rejected source decision. The following reviewed candidates remain explicit unavailable observations instead of being silently omitted:
  • pboc_aggregate_financing_flow
  • pboc_new_rmb_loans
  • pboc_m2_yoy
  • pboc_policy_liquidity_operation
  • gacc_exports
  • gacc_imports
  • gacc_trade_balance
PBoC candidates remain blocked when www.pbc.gov.cn robots policy disallows the reviewed paths or terms review is incomplete. GACC candidates remain blocked when english.customs.gov.cn cannot pass the TLS/source preflight. Their pillars therefore remain unavailable; another publisher is not substituted.

​
Revisions and direction

Each official observation retains its observation period, publication time, retrieval time, source URL, vintage ID, revision sequence, and supersession state. A correction creates or updates a traceable vintage; it does not rewrite the historical point-in-time record. Direction is calculated only when the published series contract supplies a valid comparison. Missing comparison values remain unavailable. The snapshot is launch-ready only when all five required observations are valid and within their individual age budgets. Transport freshness and snapshot completeness are written as separate seed metadata. GET /api/economic/v1/get-china-macro-snapshot reads the canonical economic:china:macro:v2 seed and never fans out to upstream publishers on a cache miss. The macro Railway member runs every 36 hours.

​
Release calendar

The release calendar reads the current NBS calendar from www.stats.gov.cn. Loan Prime Rate dates are generated from the reviewed Chinese business-day calendar and marked provisional, then promoted to verified only when the corresponding ChinaMoney/CFETS notice is found on www.chinamoney.com.cn. Failure of the required NBS calendar fails the calendar build. Failure of ChinaMoney verification leaves LPR dates provisional and records the source decision; it does not relabel them as verified.

​
Policy and enforcement events

The policy lane polls six official agencies: Each agency is limited to one listing request and at most three reviewed document fetches per run, with a 400 ms same-host cadence. Listing responses are capped at 750 KB and documents at 2 MB. URLs must match the reviewed host and path contract. The deterministic taxonomy emits:
  • consultation_draft
  • announcement_guidance
  • final_rule
  • administrative_approval_restriction
  • investigation
  • enforcement_penalty
  • effective_date_change
  • amendment_correction_repeal_supersession
  • unknown
The published event keeps the original Chinese title and text, translation state, document number, publication and effective dates, reviewed sector/entity links, content hash, classification evidence, lineage, revisions, and full provenance. Unknown classification is retained as unknown; it is not promoted to enforcement. The Railway macro bundle refreshes this lane every 6 hours. It retains at most 120 events across complete lineages for 180 days. A failed agency preserves still-valid last-good events with transport freshness changed to error; healthy agencies continue independently.

​
Alert boundary

Consultation drafts, guidance, and unknown policy classifications do not alert. Reviewed policy/enforcement alerts require a new stable lineage. Corrections and repeat ingestion retain the same lineage for deduplication. The bounded China decision-signal composition publishes at most four valid items from this lane.
