Episode 8 — Closure Ritual (Saipem COMP2)

Context

Project: Q-21699 — Saipem COMP2
Objective: Close open RFIs (IP/EMC/FLP), lock variant/power decisions, finalize BOM/CPQ, refresh annexes for client-ready handoff with strict citation discipline.
Value Pair: Deliver a defensible, evidence‑backed compliance packet with zero approximate citations.
SEA intent: Enrich (citation precision, variant/power lock), Accelerate (annex coherence), Streamline (EP mirroring).

Gate Results (TOTE)

Test: Are EP items Attached/Parked and mirrored in manifests + CSV Decision_Notes?
Operate: Attached EP‑001..EP‑006 under Trial Runs/Q-21699 - Saipem COMP2/CF04/input/EP/; added parked EP‑007 (EMC), EP‑008 (ATEX/IECEx register), EP‑009 (IP certificates). Mirrored in Evidence_Pack_Checklist_Q-21699.md, Attachments_Manifest_Q-21699.md, and CF02/output/Compliance_Matrix_Extended.csv Decision_Notes.
Test: Items enumerated with statuses; referenced‑only disallowed without RFI.
Exit: PASS — Attached/Parked mirrored. EMC/register/IP pending vendor response (RFIs open).

Test: Do High‑Risk rows have Doc_No + Section_Title + precise lines or Missing_Source with RFI link?
Operate: CF02/output/Spec_Crosswalk_Q-21699.md extended with R-HAZ-002 (Ex d default, lines 1771–1780).
Test: Template parity with Section_Title + Page/Line_Range.
Exit: PASS.

Test: each_row_has(status && evidence) && haz_component_matrix_present && weakest_link_flag && variant_locked && power_decided && environmental_minima_met_with_evidence && regulatory_declarations_attached_or_RFI
Operate: Locked variant to FLP Ex d; decided to include step‑down transformer 240→230 Vac for 3 kW heater; updated Hazards Component Matrix and Decision Table; staged EP items; recomputed weakest‑link.
Test: Decision Table and Hazards Matrix updated with evidence and EP links.
Exit: PASS (with RFIs open for IP/EMC/FLP certs).

Test: attachments_manifest_present && quality_docs_manifest_present && reference_list_present && links resolve
Operate: Refreshed manifests; materialized Spec Reference Register; updated Technical Handoff Summary.
Test: Links are repo‑relative and resolve.
Exit: PASS.

CSV Coupling Rubric (SoT)
- Standard: Maintain Compliance_Matrix_Extended.csv as source‑of‑truth; mirror EP Item_IDs in Decision_Notes.
- Rationale: Ensures downstream consistency and auditability across artifacts.
EP Mirroring Policy
- Standard: Every EP item is Attached or Parked; statuses mirrored across Evidence Pack checklist, Attachments Manifest, and CSV Decision_Notes.
- Rationale: Eliminates referenced‑only ambiguity; enforces Evidence Pack gate.
Citation Style Enforcement
- Standard: Doc_No + Section_Title + Page/Line_Range; repo‑relative paths only (Design & Build Workshop/.../Citation_Style.md).
- Rationale: Zero‑approximation citations enable external audit and rapid re‑location.
Variant & Power Gates
- Standard: In CF03, require explicit Variant_Decision per component and Power_Decision per site baseline; block exit if unset.
- Rationale: Prevents late rework; drives CPQ accuracy.
CPQ Mapping Linking
- Standard: Group by subsystem; link each row to Req_ID/Deviation_ID; include implied Ex d ancillaries where variant/power decisions require them.
- Rationale: Speeds CPQ entry and keeps config traceable to requirements.

Status: All Episode 8 gates passed with RFIs tracked; artifacts updated and linked with precise citations.
Handoff: This closure ritual and updated artifacts are sufficient to launch Episode 9 without referring to chat.
