The graph grows automatically with every completed node analysis. Every correction the chair makes is logged separately as a fine-tuning signal — export via the toolbar once enough corrections accumulate (50+ recommended).

✕

High-confidence, P&ID-grounded, corroborated facts proceed automatically. Everything else routes here for mandatory chair sign-off before it can appear in a client export. This is the human-in-the-loop checkpoint — not a suggestion, a gate.

✕

Auto-generated from alarm-type safeguards (PAH, PAHH, TAH, LAL etc.) already identified in your HAZOP studies. Vendor-agnostic — compatible with DeltaV, Experion, 800xA, EcoStruxure, or any DCS. This is a starting point for formal ISA-18.2 rationalization, not a substitute for it.

KEY POINTS: The P&ID is read ONCE per study (via Claude vision) and its instruments are injected into every subsequent HAZOP call — safeguards should reference actual tags. The Expert Archive feeds the Knowledge Graph permanently, raising corroboration scores for future AI output. The correction loop captures every cell edit silently and injects the most relevant past corrections into subsequent prompts so the AI learns from Anil's judgment in real time.

✓ CHAIR REVIEW & SIGN-OFF

You are about to sign off on this worksheet as the HAZOP Chair. This marks the output as human-reviewed and professional-grade, enabling export to client-facing deliverables. Only approve if you have reviewed every cause, consequence, safeguard, and recommendation in this worksheet and are satisfied they are accurate and complete.

Every completed HAZOP study you have ever chaired is ground truth — produced with zero AI involvement, validated against real facilities. Uploading these here gives every fact EXPERT_ARCHIVE provenance, the highest trust tier in the system — outranking even live chair-corrected output. One archive study can instantly raise confidence on every future AI-generated fact that matches its patterns, before a single new study is run. This is the single most valuable thing that can be added to BlackSky.
