Phase 03 Plan 05: Frontend Presigned Upload + Quota Bar Summary

Three-step presigned upload (XHR PUT to MinIO with progress events) + sidebar QuotaBar + inline 413 quota rejection error block wired to authStore.quota reactive state

Performance

• Duration: 7 min
• Started: 2026-05-23T18:42:50Z
• Completed: 2026-05-23T18:49:24Z
• Tasks: 2 (+ 1 checkpoint awaiting human verification)
• Files modified: 5 modified, 1 created

Accomplishments

• 3-step upload flow (STORE-03): stores/documents.js replaces the legacy api.uploadDocument() multipart call with: (1) api.getUploadUrl() → (2) uploadToMinIO() XHR PUT with xhr.upload.addEventListener('progress', ...) → (3) api.confirmUpload(). Progress mapped 0%→5%→90%→92%→100% per UI-SPEC. No Authorization header on MinIO PUT (T-03-22). uploadProgress ref map keyed by ${file.name}__${Date.now()} (T-03-25).

• Quota state in auth store (STORE-04): stores/auth.js adds quota = ref({used_bytes:0, limit_bytes:0}) and fetchQuota() async action. Called after every successful upload and every document delete. Silent catch keeps last-known values intact on error.

• QuotaBar.vue sidebar widget (STORE-04): New component at frontend/src/components/layout/QuotaBar.vue. onMounted triggers fetchQuota. Computed pct/barColor/labelColor/label from authStore.quota. Color thresholds: bg-indigo-500 (<80%), bg-amber-500 (80-95%), bg-red-500 (>=95%). Skeleton loading state; v-if hides entirely on loadFailed. Embedded in AppSidebar between </nav> and footer div.

• Quota rejection error block (STORE-05): UploadProgress.vue renders inline red error block (role="alert") when item.quotaError is set — populated from err.payload on 413. Shows rejected_bytes, used_bytes, limit_bytes from server response (T-03-23 — never from client-side file.size). "Manage storage →" uses plain <a href="/settings">.

• api/client.js structured 413: request() extended — if (!res.ok) block detects typeof body.detail === 'object', attaches err.status = res.status and err.payload = body.detail. Legacy uploadDocument() multipart function removed.

Task Commits

1. Task 1: Refactor stores + api/client + UploadProgress — eb18428 (feat)
2. Task 2: Create QuotaBar.vue + embed in AppSidebar — 23c568a (feat)

Files Created/Modified

• frontend/src/api/client.js — Extended request() error handling; removed uploadDocument legacy multipart
• frontend/src/stores/auth.js — Added quota ref + fetchQuota action
• frontend/src/stores/documents.js — 3-step upload with XHR, uploadProgress map, fetchQuota calls
• frontend/src/components/upload/UploadProgress.vue — Progress bar per row, quota rejection error block
• frontend/src/components/layout/QuotaBar.vue — New: sidebar quota widget
• frontend/src/components/layout/AppSidebar.vue — Import + embed QuotaBar

Decisions Made

• Plain <a href="/settings"> in quota error block rather than <router-link> — avoids router-link import dependency in an upload component that may not have router context in all test scenarios. Functional equivalence for the Phase 3 use case.
• uploadProgress entries not cleared by the store — DropZone/parent component owns row lifecycle and clears on dismiss. Keeps progress bar/error visible until user action.

Deviations from Plan

None — plan executed exactly as written. All implementation notes from the plan prompt were followed precisely.

UI-SPEC Deviations

Element	UI-SPEC	Implemented	Reason
Manage storage → link	<router-link to="/settings"> or plain <a>	Plain <a href="/settings">	Plan explicitly notes "use plain <a href='/settings'> to avoid router-link import complexity"
Upload progress track bg	bg-gray-100	bg-gray-100	Matches
QuotaBar track bg	bg-gray-200	bg-gray-200	Matches

No functional UI-SPEC deviations.

Issues Encountered

None.

Known Stubs

None — all data flows are wired to real API responses. QuotaBar reads from authStore.quota which is populated by /api/auth/me/quota. UploadProgress quota error block reads from 413 response body (not client-side file.size).

Threat Flags

No new threat surface introduced — this plan modifies only frontend JavaScript files. All security mitigations from the threat register implemented:

Threat ID	Status
T-03-22	MITIGATED — uploadToMinIO helper uses bare XMLHttpRequest with NO Authorization header
T-03-23	MITIGATED — Quota rejection error block populates used_bytes/limit_bytes/rejected_bytes from 413 response body only
T-03-25	MITIGATED — uploadProgress key = ${file.name}__${Date.now()} composite
T-03-26	MITIGATED — authStore.fetchQuota wraps in try/catch; QuotaBar hides on loadFailed

Next Phase Readiness

• Phase 3 is now feature-complete pending human checkpoint (Task 3) approval
• Task 3 human checkpoint requires: docker compose running, dev server at localhost:5173, logged-in non-admin user with quota row
• After checkpoint approval: Phase 3 verification (/gsd:verify-work 3) can begin
• Phase 4 (folder navigation, PDF preview, sharing) has no blockers from Phase 3

Self-Check: PASSED

• frontend/src/components/layout/QuotaBar.vue exists
• frontend/src/api/client.js contains getMyQuota (grep count: 1) and does NOT contain uploadDocument
• frontend/src/stores/documents.js contains uploadToMinIO, XMLHttpRequest, getUploadUrl, confirmUpload, fetchQuota
• frontend/src/stores/auth.js contains fetchQuota (count: 2)
• frontend/src/components/upload/UploadProgress.vue contains role="progressbar" and Not enough storage
• frontend/src/components/layout/QuotaBar.vue contains role="progressbar" and useAuthStore
• frontend/src/components/layout/AppSidebar.vue contains <QuotaBar and QuotaBar from './QuotaBar.vue'
• Frontend build exits 0 (npm run build — verified)
• No legacy uploadDocument references in frontend/src/ (grep clean)
• Task 1 commit eb18428 exists
• Task 2 commit 23c568a exists
