WorldMonitor’s China decision-signal surface is a composition boundary, not a new source or scoring method. It publishes the reviewed outputs of six existing domain lanes in one stable order:
  1. macro
  2. policy-enforcement
  3. cross-strait-activity
  4. corporate-disclosures
  5. corridor-conditions
  6. activity-nowcast
Every group reports available, partial, stale, or unavailable. An outage or invalid provenance envelope fails closed inside that group without hiding unrelated healthy groups. Public responses include at most four items per group and state how many additional valid items were omitted. Those group states are not source-health verdicts. Three separate questions must stay distinct:
  • Source coverage asks whether the launched upstream lanes are reachable, fresh, and producing contract-valid snapshots.
  • Decision-group population asks whether a reviewed source snapshot contains at least one qualifying, provenance-valid decision item. A healthy corporate-disclosure query can therefore be an unpopulated healthy_quiet_window without being an incident.
  • Contract parity asks whether the RPC and bootstrap projections both satisfy the same ordered six-group schema. Parity can be healthy while one or more groups are quiet, insufficient, stale, or unavailable.
Unavailable groups carry a bounded metadata.unavailableCause. Known causes include healthy_quiet_window, insufficient_data, provenance_rejected, and upstream_unavailable; the generic reason is used only when composition cannot determine a more specific truthful cause. Insufficient activity-nowcast groups retain their exact bounded missingInputs and missingInputFamilies diagnostics rather than discarding them with the absent derived item.

One contract across surfaces

The same china-decision-signals/v1 JSON contract backs:
  • the China country brief;
  • GET /api/intelligence/v1/get-china-decision-signals;
  • the Pro MCP tool get_china_decision_signals;
  • the on-demand bootstrap key chinaDecisionSignals;
  • the Railway canonical cache key intelligence:china-decision-signals:v1; and
  • the operator-only freshness entries in /api/health and /api/seed-health.
Anonymous dashboard and public-RPC readers receive the bounded summary. Pro MCP readers receive the same items and provenance rather than a higher-risk source expansion. Detailed cache names, request health, and freshness thresholds remain operator-only.

​
Provenance and missingness

Each item carries the complete decision-signal provenance envelope: publisher class, evidence URL or explicit non-applicability, original reference, language and translation state, distinct observation/publication/effective/ retrieval times, revision and supersession, extraction and classification confidence, corroboration, transport/content freshness, and derivation. Government ministries, state-controlled media, exchanges, independent observations, market publishers, and derived outputs remain distinct. Official publication is not treated as independent corroboration. The activity nowcast is a deterministic directional comparison with named input signal IDs; it is not an opaque China risk score. The public surface does not expose detailed bilateral trade rows, broad military identity ranges, raw ADS-B/AIS arrivals, or source-health internals. Missing values remain explicit instead of being converted to zero, normal, or current.

​
Alert policy

Alerts are narrower than the snapshot:
  • the first canonical snapshot never fans out historical records;
  • consultation drafts, guidance, unknown policy classifications, and raw cross-Strait arrivals do not alert;
  • reviewed policy/enforcement and corporate events alert only for a new stable lineage;
  • revisions, corrections, and repeat ingests retain that lineage and dedupe;
  • cross-Strait alerts require a transition between transparent 30/90-day median bands; and
  • activity-nowcast alerts require a deterministic comparison-state transition.
This surface emits only low or medium severity. Typed events use a 24-hour dedupe cooldown; baseline and nowcast transitions use 12 hours. High or critical escalation remains the responsibility of a separately reviewed alert policy, not source arrival volume.

​
Deployment audit

The derived-signals Railway bundle refreshes the canonical composition every 15 minutes. The seeder reads the public RPC, validates the six ordered groups, publishes the canonical key, and then writes seed-meta:intelligence:china-decision-signals. Alert delivery runs only after canonical publication. Failed deliveries remain in a durable deduplicated outbox for the next seed run; they never roll back the published snapshot. The audit has two halves, and each one is enforced somewhere different. The static half runs on every pull request through tests/china-decision-parity-audit.test.mjs under npm run test:data. It confirms the six-domain composition is still registered across the API, MCP, bootstrap, health, alert, Railway, and documentation surfaces. Most of those registrations are checked by token presence, which proves a surface was not deleted or renamed. For the surfaces where a silent unwiring costs the most — gateway cache tier, anonymous gateway reachability, and the three access tiers — the audit instead reads the real container and asks whether the value is a member of it, so a commented-out entry or a dead duplicate reads as a failure rather than a pass. The access-tier gate is additionally proven by executing the published-snapshot validator against downgraded tiers. Run it locally before release:
The live half runs against a deployment, so no pull request can exercise it. It is enforced by the china-decision-parity-live.yml workflow, which probes production every six hours, on pushes to main that touch the audit, and on demand. Run it manually against a freshly deployed staging environment with the public base URL:
--require-live makes the command fail when no URL reaches the probe, so an automated caller cannot report a staging audit it never performed. The base URL must be https on a public host — loopback, link-local, and private ranges are rejected, because the probe reports reachability and latency for whatever it is pointed at. The live probe validates both the composition RPC and the public chinaDecisionSignals bootstrap projection, including a one-hour maximum canonical age. It prints only route status, latency, generation time, group states, and the prominent populated, partial, stale, and unavailable group counts. It never prints environment variables, API keys, Redis values, source documents, or detailed trade records. Ordinary parity remains schema-only and accepts legitimately unpopulated groups. A release or operator audit that requires specific populated groups can opt into an explicit assertion:
The operator-only /api/seed-health entry and seed log expose the same bounded per-group states and counts. Anonymous compact /api/health?compact=1 continues to omit chinaDecisionSignals entirely.
