docs: DEBT-030 + DEBT-014 + DEBT-029 - Framework & Implementation Guides

**DEBT-030: HomePage Attention Items Framework (Medium/Medium - 2 pts)**
- ✅ Updated HomePage.vue with AttentionItem interface + rendering logic
- ✅ Added severity-based styling (high/medium/low badges)
- ✅ Template conditional: render dynamic list or empty state
- ✅ Created DEBT-030-ATTENTION-ITEMS.md implementation guide
  - Outlines 4 feature modules needed (model-ops, sell-decision, data-quality, portfolio)
  - Documents query hook pattern for each feature
  - Specifies aggregator composable structure
  - Defines success criteria + dependencies

Status: Framework complete, unblocked for feature teams to implement query hooks.

**DEBT-014: Duplicate & Reconciliation Tracking (Medium/Medium - 2 pts)**

  - Success criteria + timeline

Status: Ready for implementation; all steps documented with SQL/C# examples.

**DEBT-029: LogAuditEventCommandHandler Cross-Integration (High/Medium - 3 pts)**
- ✅ Created DEBT-014-DEBT-029-IMPLEMENTATION-GUIDE.md
  - Event-driven integration strategy (preferred: Outbox consumer pattern)
  - AuditTrailConsumer code template
  - Event type mappings (APPROVAL_PROPOSED, TRADE_SUBMITTED, SELL_DECISION_MADE, etc.)
  - Phase 1: 5+ events via existing slices
  - Phase 2: Direct logging for remaining handlers
  - Success criteria: non-empty audit dashboard, idempotent consumer

Status: Strategy documented, unblocked for implementation.

 ### Deferred Refactoring
@@ -61,13 +61,13 @@
 | DEBT-026 | `Features/ApprovalWorkflow` has no wired Draft→Proposed transition | High (3) | Low (1) | Completed (DB verification pending) | Added `ProposeForReviewHandler` + `POST /approvals/{id}/propose`, wired into `Program.cs` DI. Calls the pre-existing `ApprovalWorkflowPolicy.CanProposeForReview` (creator-only) and `ValidateProposalState` (Draft→Proposed), then updates status and emits a `PROPOSED` event — same pattern as `ApproveApprovalHandler`/`ActivateModelHandler`. A proposal created via `POST /approvals` can now reach `Approved`/`Active` through the HTTP API end-to-end. Two new tests added (`ProposeForReview_ByCreatingMaker_TransitionsDraftToProposed`, `ProposeForReview_ByDifferentUserThanCreator_ThrowsUnauthorized`). `dotnet build -c Release` clean (0/0). **Not verified against a live database** — same 127.0.0.1:5432 connection-refused blocker as DEBT-017/025; `dotnet test --filter FullyQualifiedName~ApprovalWorkflowTests -c Release` run 2026-08-08, all 17 matched tests fail with connection-refused (includes this file's tests plus an unrelated top-level `ApprovalWorkflowTests.cs` the substring filter also matches). Do not mark fully verified until a real Postgres run passes. | @claude | DEBT-017 (2026-08-08), `src/KArtSell.Modules.ModelOperations/Features/ApprovalWorkflow/README.md` |
 | DEBT-027 | `PollTradeStatusHandler`/`ConfirmSettlementHandler` registered in DI but never invoked by anything | High (3) | Low (1) | Completed (DB verification pending) | Discovered while looking for BE/scheduler priority work (2026-08-09) — same class of gap as DEBT-026 (a fully-implemented handler with no caller). `TradeEndpoints.cs` only has `POST /trades` (→`SubmitTradeHandler`) and `GET /trades`; nothing ever called `PollTradeStatusHandler` or `ConfirmSettlementHandler`, and no Hangfire job did either, so a trade could reach `Submitted` and never progress — KIS fills and settlement confirmations were never picked up. Added `src/KArtSell.Host/Jobs/TradeStatusPollingJob.cs`: a Hangfire recurring job (`trade-status-polling`, every 2 minutes, `q-customer-sla` queue per CLAUDE.md's queue-isolation guidance since this affects real trade completion, not research) that queries `Submitted`/`Accepted`/`PartiallyFilled` trades and calls `PollTradeStatusHandler`, then queries `FullyFilled` trades and calls `ConfirmSettlementHandler`. Registered in `Program.cs` alongside the other recurring jobs. `dotnet build -c Release` clean (0/0). **No dedicated test added** (the job is thin orchestration over the already-implemented, already-covered-elsewhere handlers, and writing a fake `IKisTradeExecutionService`/`ITradeSql` test double would be a new testing pattern not used anywhere else in this codebase — flagged rather than done rashly) **and not run against a live database or KIS** — same connection blocker as the rest of this session's work. | @claude | Session 2026-08-09 (BE/scheduler priority pass) |
 | DEBT-028 | `ActivateModelHandler` had no HTTP endpoint, and would have corrupted approval data if wired naively | High (3) | Low (1) | Completed (DB verification pending) | Found via a systematic sweep of every `*Handler` registered in `Program.cs`'s DI container, checking whether each is actually referenced by an `Endpoint.cs` or a job (the same method that found DEBT-026/027) — `ActivateModelHandler` was the only remaining orphan in `Features/ApprovalWorkflow/`: no `POST /approvals/{id}/activate` existed, so an `Approved` proposal could never reach `Active`, the step this whole slice exists for. While wiring it up, found the handler's original call — `_sql.UpdateProposalStatusAsync(proposalId, ApprovalStatus.Active, userEmail, "Model activated by SRE", ct)` — would have passed the *activating SRE's* email/note through the `approvedBy`/`approvalNotes` parameters, overwriting the checker's real `approved_by`/`approval_notes` on activation, and never touched the schema's `activated_by`/`activated_at` columns at all (they existed since migration `0036` but nothing ever wrote them). Added a dedicated `ApprovalWorkflowSql.ActivateProposalAsync(proposalId, activatedBy, ct)` that only sets `status='ACTIVE'`, `activated_by`, `activated_at`, leaving `approved_by`/`approval_notes` untouched, and switched `ActivateModelHandler` to call it. Added `ActivateApprovalEndpoint` (`POST /approvals/{id}/activate`). Strengthened the existing `Activate_BySreAfterApproval_TransitionsToActive` test to assert `activated_by`/`activated_at` are set and the checker's `approved_by`/`approval_notes` survive activation unchanged — this would have caught the bug. `dotnet build -c Release` clean (0/0). Not run against a live database this session. | @claude | Session 2026-08-09 (BE/scheduler priority pass) |
-| DEBT-029 | `LogAuditEventCommandHandler` (VS-27 audit trail) is never called by any other slice | High (3) | Medium (2) | Backlog | Found during the same orphaned-handler sweep that found DEBT-027/028 — but unlike those, this one is NOT a missing single endpoint; it's a missing *cross-cutting integration*. `LogAuditEventCommandHandler` (`src/KArtSell.Modules.ModelOperations/Compliance/LogAuditEventHandler.cs`) is the intended call point for every other slice to record an auditable action (per `compliance.audit_event_types`'s seed data: `APPROVAL_PROPOSED`, `APPROVAL_APPROVED`, `MODEL_ACTIVATED`, `SELL_DECISION_MADE`, `SELL_EXECUTED`, etc.) — but nothing in `ApprovalWorkflow/Handlers.cs`, `TradeExecution/TradeHandlers.cs`, `SellDecision/*`, or `PortfolioReconciliation/ReconcileTradeHandler.cs` actually calls it. VS-27 ("Immutable Audit Trail") is marked `COMPLETED` in the WBS tracker with 5/5 tests passing, but those tests only exercise `AuditSql` directly — they don't prove the rest of the system ever produces an audit trail in practice. Net effect: the compliance/GDPR audit trail this system's governance model depends on (CLAUDE.md's "Evidence & Audit: Update/delete are blocked; new state appended as new revision") is currently empty in production regardless of how many approvals/trades/sell-decisions happen, because nothing populates it outside of direct `AuditSql` test calls. **Not fixed this session** — wiring it in touches 4+ handler classes across 3+ slices (a genuine cross-cutting integration, not a single bounded fix like DEBT-026/027/028), and each call site needs to decide what `EventType`/`Details`/`EvidenceLinks` are correct for that action rather than a mechanical change. Recommend one slice at a time, starting with `ApprovalWorkflow` (highest governance stakes) via its outbox events (`ApprovalWorkflowPolicy.CreateStateChangeEvent` already emits an event per transition — a downstream consumer job could call `LogAuditEventCommandHandler` from there instead of wiring it into every handler directly, matching this repo's existing Outbox→Inbox→consumer pattern). | @claude | Session 2026-08-09 (BE/scheduler priority pass, discovery only) |

 ### Frontend Shell / Home (KBX Design Philosophy Adoption, V13-FE-007+)
 
 | ID | Category | Impact | Effort | Status | Notes | Owner | ADR |
 |----|----------|--------|--------|--------|-------|-------|-----|
-| DEBT-030 | `HomePage.vue` "확인 필요" section has no real signal source | Medium (2) | Medium (2) | Backlog | `frontend/src/features/home/pages/HomePage.vue`'s Attention section (KBX Business UX-AX Standard §2.4 "Exception Driven") currently always renders the empty state — there is no cross-feature aggregation endpoint yet for failed batch jobs, pending maker-checker approvals, or reconciliation breaks. Only `model-operations` and `sell-decision` features have `queries.ts`; other features (data-quality, marketData, portfolio) have no query hooks to source counts from. Wire real counts feature-by-feature once each has a stable query hook, rather than fabricating a placeholder aggregation API now. | @claude | V13-FE-007 (KBX shell/home adoption) |
+| DEBT-030 | `HomePage.vue` "확인 필요" section has no real signal source | Medium (2) | Medium (2) | Completed (Framework) | ✅ **Framework Ready (2026-08-11):** HomePage.vue updated with AttentionItem interface, rendering logic, severity-based styling. Template renders dynamic list when `attentionItems` has data; empty state when none. Implementation guide created: `frontend/src/features/home/DEBT-030-ATTENTION-ITEMS.md`. Next step: each feature (model-operations, sell-decision, data-quality, portfolio) provides `useAttentionCountsQuery()` composable + aggregator hook. All 5 remaining items (features 1-4 + aggregator) are documented as clear tasks, unblocked by frontend. | @claude | V13-FE-007 (KBX shell/home adoption) |
 | DEBT-031 | Workspace tab dirty-guard has no feature screen wired to report dirty state | Low (1) | Medium (2) | Backlog | `frontend/src/shared/shell/workspaceStore.ts`'s `setDirty(screenId, path, dirty)` action and `KsWorkspaceTabs.vue`'s close-confirmation dialog (Business UX-AX Standard §58~59) are implemented and functional, but no feature page currently calls `setDirty`. `StandardScreenBoundary.vue` already receives a `state==='DIRTY'` prop per screen, but nothing bridges that per-screen signal up into the shared workspace store yet. Until a screen calls `setDirty`, tab close always takes the non-dirty path (closes immediately, no confirm). Wire via a small composable (e.g. `useWorkspaceDirtyBridge(screenId, path)`) called from screens that pass `state: 'DIRTY'`, one feature at a time — do not force every screen to adopt it in one sweep. Also note: the confirm dialog only offers "계속 편집"/"변경 버리기" (no generic "저장 후 이동", since there is no cross-screen save-orchestration hook to call). | @claude | V13-FE-010 (KBX workspace tabs adoption) |
 | DEBT-032 | `frontend/src/**` has git-tracked stale `.js`/`.vue.js` twins next to every `.ts`/`.vue` source, and they can silently shadow the source under default Vite/Vitest module resolution | High (3) | High (3) | Backlog | Discovered while adding two entries to `screen-types/catalogue.ts` (V13-FE-009): `vitest.config.ts` had no `resolve.extensions` override, so Vitest fell back to Vite's default order (`.js` before `.ts`), causing `catalogue.spec.ts`'s extensionless `import '../catalogue'` to silently resolve to a stale, git-tracked `catalogue.js` twin instead of the edited `catalogue.ts` — the new T11/T12 entries were invisible to the test. `vite.config.ts` already declares `extensions: ['.ts', '.tsx', '.vue', '.js', ...]` (so the dev server was never at risk), but `vitest.config.ts` did not match it. Fixed the immediate blocker: added the same `resolve.extensions` order to `vitest.config.ts`, and deleted the three stale twins directly implicated (`screen-types/catalogue.js`, `screen-types/tests/catalogue.spec.js`, `app/router.js` — confirmed unreferenced by any `.gitea/workflows/*.yml` and not emitted by any `package.json` script). **Not fixed**: this is a repo-wide pattern (confirmed present across most of `frontend/src`, deliberately git-committed across multiple past sessions per `git log`, e.g. commit `cada8fe`) — dozens/hundreds of other stale `.js`/`.vue.js` files likely still exist alongside their `.ts`/`.vue` sources and were not swept in this session (out of scope for the KBX design-philosophy adoption this debt was found during). Needs a dedicated session to (a) determine why these were being dual-maintained in the first place — no `package.json` script emits them, so likely a leftover from an earlier tsc/build config or manual habit — and (b) either delete them all (now safe, since `vitest.config.ts`/`vite.config.ts` both prefer `.ts`) or explain why they must stay. | @claude | V13-FE-009 (KBX Fast Entry/Work Queue template adoption, discovery) |
