Episode 9 — Retrospective Ritual (Tecnmont SKIKDA)
What Worked (SEA)
- Streamline: CSV SoT created immediately; EP items staged as Parked and mirrored across manifests + CSV Decision_Notes.
- Enrich: Locked variant (hazardous‑area config), power (heater 240 V 1Φ), with precise offer/spec citations; hazards matrix computed with weakest_link_flag.
- Accelerate: Spec Cross‑walk built with Section_Title + Page/Line; CPQ list pre‑grouped by subsystem (alarms 24 VDC, Ex e JB, optional Ex d chiller).
What Didn’t / Friction Observed
- EMC declaration and Ex/IP certificates not attached; reliance on references in the codes index and Vendor Data Book slowed gate confidence.
- IP minima ambiguity (spec IP65 vs potential outdoor IP66 expectation) needs explicit confirmation or upgrade path.
Standards Deltas (Implemented)
- CSV coupling: Decision_Notes now consistently mirror EP Item_IDs; kept CSV schema intact.
- Cross‑walk discipline: Added explicit Section_Title + Page/Line for IP minima (spec), area class minimums, variant/power, and chiller IP/power.
- Hazards table: Added explicit Ex e JB vs Ex d chiller differentiation; weakest_link_flag set by evidence posture.
Metrics & Signals (qualitative)
- Evidence completeness: EP items Parked; RFI issued for EMC and ATEX/JB/IP certificates.
- Gates: variant_locked true; power_decided true; environmental minima cited; regulatory declarations → RFI.
- CPQ readiness: subsystem mapping covers alarms 24 VDC, Ex e JB, optional Ex d chiller.
Hypotheses for Episode 10
- If EMC and Ex/IP certificates arrive early, weakest_link_flag can be cleared and statuses flipped to Compliant without rework.
- Explicit outdoor IP66 confirmation (or upgrade) will preempt TBE queries and stabilize the hazards matrix.
Next Actions (feed to Episode 10 Onramp)
- Attach vendor EMC declaration (IEC 61000/61326/NAMUR) and ATEX/IECEx certs; update EP statuses from Parked→Attached.
- Confirm IP target (IP66 vs IP65) and JB/signage Ex/IP specifics; update hazards matrix and Decision Table accordingly.
- Finalize CPQ mapping with any chiller selection and corresponding power variant.
