EARLY WARNING EW-0001

DE vibration: –

Seal pot > 2.0 barg for 12 h: –

Rule: a 1-of-2 combination, gated on YS1026.RUN ≥ 1, of an ISO-zone child on VT1013.DE (ISO 10816-3 group 1 zones, baseline 2.0 mm/s, alarm 3.125 mm/s held 24 h) and a threshold-sustained child (PT1015 > 2.0 barg for 12 h). One child active raises an advisory (medium); both active escalate it to high (staged alerting, ISA-18.2 priority). In REPLAY the states are precomputed from the seed; in LIVE · UNS the page evaluates the same rule on the live samples' timestamps.

Generated from the synthetic AIM (sample/assets.json, relationships.json FEEDS, tags.json) by docs/pid/build_pid.py. Values are a playback of the synthetic seed's last 30 days (2026-09-06 → 2026-10-06 07:00 UTC), looping; tags marked "proposed" are plan §6 proposals. Symbols follow ISO 10628 / DEXPI TrainingTestCases conventions (CC BY 4.0, reference only). An illustrative refinery, not a real plant. Live mode: open with ?uns=wss://host:port/path to read proto/tags/<tagId> from the UNS (MQTT over WebSocket); without it, or when the UNS is quiet for 30 s, the page replays.
