102 Full Sweep Improvement Coverage Delta Report

Date: 2026-04-19 Roadmap: docs/superpowers/plans/2026-04-19-102-full-sweep-improvement-roadmap-plan.md Baseline: tests/fixtures/generated_scene/full_sweep_dry_run_2026-04-19.json Follow-Up: tests/fixtures/generated_scene/full_sweep_improvement_followup_2026-04-19.json

Headline Delta

Metric	Baseline	Follow-up	Delta
Dry-run auto-pass	40	48	+8
Dry-run actionable coverage	66	96	+30
Timeout / source-unreadable	31	2	-29
Misclassified	5	4	-1
Fail-closed-known	26	48	+22

The increase in fail-closed-known is expected. The roadmap converted many timeout/no-report cases into structured fail-closed outputs instead of process-level failures.

Follow-Up Status Counts

Status	Count
`auto-pass`	48
`fail-closed-known`	48
`misclassified`	4
`source-unreadable`	2
`missing-source`	0
`unsupported-family`	0
Total	102

Remaining Timeout Cases

Only 2 timeout cases remain:

任务报表
力禾动环系统巡视记录

These are not known-family samples.

Remaining Misclassification Cases

4 route conflicts remain:

Scene	Expected group	Inferred archetype
`95598报修工单日管控`	`G3`	`host_bridge_workflow`
`95598重要服务事项报备统计表`	`G3`	`host_bridge_workflow`
`台区线损台区月度高负损预测`	`G2`	`host_bridge_workflow`
`配网支撑月报(95598抢修统计报表)`	`G3`	`host_bridge_workflow`

One previous G1-E conflict, 高低压新增报装容量月度统计表, now returns to single_request_enrichment and auto-passes.

用电报装信息统计列表 now returns to single_request_enrichment but remains fail-closed, so it is no longer a route-overpreference case.

Structured Fail-Closed Result

The baseline had 25 no-report failures. The follow-up emits structured fail-closed reports for these paths, with:

inferred archetype
generationStatus = fail-closed
failureStage = readiness-before-report
blocker reason
readiness missing pieces and risks

This makes failures machine-readable without weakening gates.

Interpretation

The roadmap delivered measurable improvement:

timeout noise was reduced from 31 to 2
auto-pass increased from 40 to 48
actionable coverage increased from 66 to 96
no-report failures were converted into structured fail-closed results

Remaining work is no longer the same broad ambiguity. The next blocker is the smaller route-conflict set, especially G3/G2 vs host_bridge_workflow.

Stop Statement
