T862 — sweep funnel counters and api

Status: done（2026-08-11） Milestone: M6 Est. change: ~180 lines

Goal

完成後 Sweep／Explore API 與列表可回傳完整 funnel、credit breakdown、failure／deferred reason，且數量語意可對帳。

Depends on

• T860、T861、T800

Inputs

• apps/backend/internal/module/radar/domain/sweep.go
• apps/backend/internal/logic/radar/list_sweeps_logic.go
• apps/backend/internal/logic/radar/explore_opportunities_logic.go
• Spec §7.2、§7.6、驗收 #14、#15、#19

Outputs

程式變更（預期路徑）

路徑	動作	說明
apps/backend/internal/module/radar/domain/sweep.go	edit	counters／breakdown serialization
apps/backend/internal/logic/radar/list_sweeps_logic.go	edit	owner list mapping
apps/backend/internal/logic/radar/explore_opportunities_logic.go	edit	preview、ceiling、result stats
apps/web/src/data/live/radarRepos.ts	edit	Sweep／Explore mapper

行為變更

• created 不含 merged；prefilter_rejected 不含 AI judge；credits 分 search／demand_map／judge／reply。

API / 契約（若有）

• list 維持 pagination/list、UTC ns、102000 success envelope。

Out of scope

• 不做新前端 funnel 視覺（T823 已完成 mock）。

Acceptance

• API counters 與 repository domain 同數值。
• 失敗／partial 不回成功空 Sweep。
• 指令：

cd apps/backend && go test ./internal/logic/radar ./internal/module/radar -run 'Sweep|Explore' -count=1

Notes

所有 credits_used 必須能回指既有 usage event source。
