---

Phase 1 — Critical Bug Fixes (Autonomous)

P1.1 — Error Swallowing (CRITICAL C1)

Issue: getEmails/searchEmails return empty on transport failure. Network-down = empty folder.

Fix: Sample transportHealth().transportFailureCount() before/after JMAP reads. If incremented, throw TransportError instead of returning { emails: [], ... }. Store catches and shows connectivity banner.

• Files: lib/jmap/client.ts, stores/email-store.ts, lib/jmap/transport-health.ts
• Reuse: None
• Effort: 2h

P1.2 — FTS5 Schema-Drop Rebuild (CRITICAL C6)

Issue: Schema version bump drops all tables without auto-rebuild.

Fix: After DROP TABLE IF EXISTS, trigger automatic catchUpAll() in the same operation. Add user-facing "Rebuilding search index..." indicator.

• Files: lib/mail-index/store.ts, lib/mail-index/reindex.ts
• Reuse: None
• Effort: 2h

P1.3 — Auth Credentials in localStorage (CRITICAL C5)

Issue: auth-storage + account-storage contain server URLs and usernames in plaintext.

Fix: Encrypt the Zustand persist payload for these two stores using a key derived from session secret or a per-device key. Scope: auth-store.ts and account-store.ts persist middleware.

• Files: stores/auth-store.ts, stores/account-store.ts, new lib/auth/local-storage-crypto.ts
• Reuse: AES-256-GCM pattern from lib/auth/crypto.ts
• Effort: 4h

P1.4 — Settings Lock Bypass (CRITICAL C7)

Issue: updateSetting() has no policy check. Admin locks bypassable via store.

Fix: Gate updateSetting(key, value) with isSettingLocked(key). Add { force: true } opt-in for legitimate bypassers (auth bootstrap, settings sync). Audit all updateSetting call sites.

• Files: stores/settings-store.ts, stores/auth-store.ts, lib/settings-sync.ts
• Reuse: None
• Effort: 3h

P1.5 — Offline Push Detection (CRITICAL C8)

Issue: No offline event listener. Transports retry blindly, draining battery.

Fix: Add window.addEventListener('offline', ...) that pauses all push transports. Add navigator.onLine gate on each transport cycle. Wire transportHealth().likelyOffline into push lifecycle.

• Files: lib/jmap/client.ts
• Reuse: None
• Effort: 1h

P1.6 — Admin Session Revocation (CRITICAL C4)

Issue: AES-256-GCM token has no server-side revocation.

Fix: Add in-memory token blacklist (Set with TTL) in admin session middleware. Logout adds token jti to blacklist. Cleanup expired entries on verification.

• Files: lib/admin/session.ts, app/api/admin/auth/route.ts
• Reuse: None
• Effort: 3h

P1.7 — Calendar ID Collision (CRITICAL C2)

Issue: Recurrence expansion (: delimiter) collides with shared event prefix.

Fix: Change expansion delimiter from : to ::occurrence::. Update stripLocalAccountPrefix and all ID parsing.

• Files: lib/recurrence-expansion.ts, stores/calendar-store.ts
• Reuse: None
• Effort: 1h

P1.8 — Calendar Cross-Account Dedup (CRITICAL C3)

Issue: Multi-account event aggregation has no UID dedup.

Fix: After Promise.all(...).flat(), run uniqueBy(events, e => e.uid + e.recurrenceId) pass.

• Files: stores/calendar-store.ts
• Reuse: None
• Effort: 1h

P1.9 — HIGH Fixes Batch

• H4: Strip access_token from OAuth error logs (lib/oauth/token-exchange.ts) — 30min
• H9: Fix bcrypt in isHashed() (lib/admin/password.ts) — 1h
• H18: Default autoSelectReplyIdentity to true (stores/settings-store.ts) — 30min
• H7: DOMPurify HTML template body on import (lib/template-utils.ts) — 1h
• H13: calendarTasksEnabled runtime enforcement (stores/task-store.ts, components/calendar/) — 2h
• H14: try/catch + toast on task mutations (stores/task-store.ts) — 1h
• H8: Derive secure cookie from x-forwarded-proto (lib/admin/session.ts) — 1h
• H3: Rate-limit user auth endpoints (app/api/auth/*) — 3h
• H2: Await state snapshot in reconcileAfterWebSocketFallback (lib/jmap/client.ts) — 2h
• H1: Push handler: add ContactCard/FileNode branches (stores/email-store.ts) — 3h

P1 Total: ~32h

Phase 2 — Missing Features (Autonomous, Code Reuse)

P2.1 — Extended Signatures (Multiple per Identity + HTML Editor)

Docx: "Add option to create various email signatures and to select standard signature for new emails and for replies"

Reuse from Angular:

• Models: signature.model.ts (Signature interface), identity.model.ts (zimbraPrefDefaultSignatureId)
• API: Signature CRUD endpoints, modifySignaturePrefs() pattern
• UI logic: Quill editor toolbar config → react-quill-new equivalent

Implementation:

1. New stores/signature-store.ts — Signature[] with CRUD + identity assignment
2. New components/settings/signature-settings.tsx — list management page
3. New components/settings/signature-editor-modal.tsx — Quill-based HTML editor
4. Extend components/identity/identity-form.tsx — default/forward-reply signature picker
5. Extend components/email/email-composer.tsx — signature selector dropdown in compose

Effort: 12h

P2.2 — Create Appointment from Email

Docx: "create a calendar entry from an email with recipients as participants and email text in description"

Reuse from Angular:

• Appointment interface from appoinment.model.ts

2. Integrate into mail sidebar or bottom-left overlay in the mail page layout
3. Show date dots for days with events, today highlight, click to navigate to calendar
4. Optionally: toggleable via user setting "Show calendar dashlet"

Effort: 8h

P2.5 — Email Import (.eml, tgz, zip)

Docx: "Missing: feature to import emails"

Reuse from Angular:

• ImportExportComponent (513 lines) — import types, destination folder, resolve settings
• preferenceService.importFromFile() — API request shape
• CSV type auto-detection logic

Implementation:

2. Add CSV column mapping UI (map CSV columns to contact fields)
3. Folder selection for import destination
4. Dedup handling

Effort: 6h

P2.7 — Free/Busy View

Docx: "Missing: free/busy view"

Reuse from Angular:

• scheduler.component.ts (1303 lines) — full free/busy grid
• scheduler-utils.ts — free-busy status constants (fba values, FBA_TO_PTST mapping)
• schedule-assistant.component.ts (1081 lines) — suggestion engine algorithm
• Free/busy URL format: {serverURL}/home/{email}?fmt=freebusy

Implementation:

1. New components/calendar/free-busy-view.tsx — attendee-row × time-slot grid
2. Color-coded slots: free (white), busy (red), tentative (yellow), out-of-office (purple)
3. Integration into event-modal when adding participants — show availability inline
4. Also queries resources_bookings table (see P2.8) to show resource availability in the same grid
5. New lib/calendar-freebusy.ts — fetch and parse free/busy data (user calendars + resource bookings)

Effort: 16h (was 14h, added resource booking integration)

P2.8 — Resources/Equipment Booking (VNCdirectory-backed PostgreSQL)

Docx: "Missing: resources/equipment" Architecture decision: Resources managed in separate PostgreSQL table, mapped to VNCdirectory for centralized cross-application management (rooms, cars, equipment, etc.). Independent from mail client — this is a platform-level resource system.

Reuse from Angular:

• calendar-equipment-dialog.component.ts (373 lines) — equipment browser UI patterns
• calendar-equipment-autocomplete.component.ts (266 lines) — autocomplete UX
• GAL query: zimbraCalResType === "Equipment" → adapt to VNCdirectory resource type filter

Backend (New):

1. PostgreSQL migration — resources table:

   • id UUID PK
   • tenant_id UUID (VNCdirectory tenant scope)
   • name text
   • type enum (room, vehicle, equipment, other)
   • location text (building/floor/room)
   • capacity integer nullable
   • description text
   • contact_email text (responsible person)
   • is_active boolean
   • metadata jsonb (extensible: photo URL, amenities, access hours, etc.)
   • created_at, updated_at timestamps

2. resources table → VNCdirectory sync — VNCdirectory is the canonical source. Options:

   • Pull model: VNCdirectory writes to this table via API/webhook
   • Push model: This service syncs changes back to VNCdirectory
   • Read-through: Query VNCdirectory directly for resource listings; cache in PostgreSQL for availability booking
   • Decision needed: which direction is authoritative? (Assume VNCdirectory → this table for Phase 1)

3. New API routes: app/api/resources/

   • GET /api/resources — list/search resources (type filter, location filter, tenant scoped)
   • GET /api/resources/[id] — single resource detail
   • GET /api/resources/[id]/availability?start=&end= — free/busy for a resource
   • POST /api/resources/[id]/book — create booking for a resource
   • DELETE /api/resources/[id]/book/[bookingId] — cancel booking

4. New lib/resources/ service layer:

   • lib/resources/client.ts — fetch/query resources from VNCdirectory or local DB
   • lib/resources/availability.ts — check resource availability for time range
   • lib/resources/booking.ts — book/cancel resource
   • lib/resources/sync.ts — sync with VNCdirectory (if push-model needed)

5. Conflict checking:

   • When booking, check resources_bookings table for overlapping time ranges
   • Return conflicts + alternative slots

Frontend:

1. Extend components/calendar/event-modal.tsx — "Resources" tab with:
   • Resource type filter (room, vehicle, equipment)
   • Searchable autocomplete (name, location, capacity)
   • Availability indicator (free/busy for event time range)
2. New components/calendar/resource-picker.tsx — reusable resource selection component
3. Booked resources appear in event detail, participant list, and email invitation

Effort: 20h (was 10h, doubled for PostgreSQL + VNCdirectory integration)

P2.9 — VNCtalk Video Meeting Integration

Docx: "Missing: integration with VNCtalk -> create Videomeeting"

Reuse from Angular:

• app.service.ts → createNewMeeting() / updateScheduledMeeting() API calls
• Payload: POST /api/createnewmeeting { name, start, end, invitees, password, description, invid?, rev?, ms? }
• createOrUpdateMeeting() in edit-appointment-dialog.component.ts — builds payload from appointment

Implementation:

1. New lib/vnctalk/client.ts — VNCtalk API client (create/update meeting)
2. Extend components/calendar/event-modal.tsx — "Create VNCtalk Meeting" toggle/button
3. Store meeting JID on CalendarEvent for updates
4. Add meeting link to event detail popover and email invitation body

Effort: 8h

P2.10 — Collabora Online Editing

Docx: "Add feature to collaborate with Collabora"

Reuse from Angular:

• owncloud.service.ts → getDocumentUrl(fileId, useCollabora) with RichDocuments API
• POST ocs/v2.php/apps/richdocuments/api/v1/document?format=json
• Config: collaboraBaseUrl from admin config

Implementation:

1. New lib/collabora/client.ts — fetch editing URL from Collabora server
2. New components/files/collabora-editor.tsx — iframe-based editor embedding
3. Extend components/files/file-browser.tsx — "Edit with Collabora" action for office files
4. Admin config: collaboraBaseUrl in policy/config

Effort: 10h

P2.11 — Calendar Enhancements Batch

Docx: Multiple calendar improvements

2.11a — Clickable links in emails

• Already partially done (TipTap Link extension). Verify link rendering in calendar event descriptions.
• Effort: 2h

2.11b — Contact details of participants

• Add popover on participant names in event-modal showing contact card. Reuse components/contacts/contact-detail.tsx data.
• Effort: 4h

2.11c — Reply / Reply to All in meetings

• Extend event-modal with "Reply" and "Reply to All" buttons that open composer pre-filled with participant emails.
• Effort: 3h

2.11d — Timezone support

• Add timezone picker to event-modal. Use date-fns-tz (already a dependency). Display times in event timezone with user timezone conversion.
• Effort: 6h

2.11e — Map links

• Extract address from event location, generate Google Maps / OpenStreetMap link.
• Effort: 2h

P2.12 — Action Wheel (Custom Radial Menu)

Docx: "Recreate Action Wheel or better functionality"

Board decision: Build custom radial menu.

Implementation:

1. New components/ui/radial-menu.tsx — SVG-based radial menu with configurable items
2. Supports: mail actions (reply, forward, delete, archive, mark read, move, tag), contact actions, file actions
3. Trigger: long-press on mobile, right-click on desktop, or dedicated button
4. Animations: CSS rotate + scale transitions
5. Keyboard accessible

Effort: 10h

P2.13 — IDP Integration — VNCdirectory Admin Configuration Panel

Docx: "IDP integration will be towards VNCdirectory (openldap, simplesamlphp, 2fa etc.)" Architecture decision: Add admin UI for configuring VNCdirectory connection settings. Reuse auth patterns from VNCmail-analysis api/auth-proxy/.

Reuse from Angular (api/auth-proxy/):

• config/config.js.example — full auth configuration schema (SAML, LDAP, VNCdirectory, 2FA, hybrid auth)
• config/passport.js — SAML strategy + JWT custom strategy setup
• routes/index.js — login/logout/SAML callback/LDAP search/2FA/TOTP routes
• utils/common.js — JWT verification, Zimbra preauth token creation
• Auth dependencies: @node-saml/passport-saml, passport, jsonwebtoken, ldapjs

Current VNCmail+ auth stack vs Angular auth stack:

Feature	Angular (Zimbra)	VNCmail+ (Stalwart)
Primary auth	SAML 2.0 via Passport	OAuth/OIDC via Stalwart
Identity source	Zimbra LDAP + VNCdirectory	Stalwart internal + OIDC
2FA	VNCdirectory TOTP/DUO	TOTP via Stalwart admin API
Directory integration	Redmine API (contactsApiUrl)	❌ None
LDAP backend	ldapjs → Zimbra LDAP	❌ None
SSO/Federation	JWT deeplinks + SAML	Cookie-based + OAuth

Implementation:

1. New lib/vncdirectory/ service layer:

   • lib/vncdirectory/client.ts — API client for VNCdirectory REST endpoints (port auth patterns from routes/index.js)
   • lib/vncdirectory/config.ts — VNCdirectory connection settings (URL, API key, LDAP bind, SAML IDP metadata)
   • lib/vncdirectory/auth.ts — SAML 2.0 SP implementation using @node-saml/passport-saml via Next.js API routes
   • lib/vncdirectory/ldap.ts — LDAP client using ldapjs for user/group/GAL queries
   • lib/vncdirectory/2fa.ts — TOTP enrollment + verification via VNCdirectory

2. New API routes: app/api/vncdirectory/

   • GET /api/vncdirectory/status — connection health check
   • POST /api/vncdirectory/saml/login — initiate SAML login flow
   • POST /api/vncdirectory/saml/callback — SAML assertion consumer
   • POST /api/vncdirectory/saml/logout — SAML single logout
   • GET /api/vncdirectory/users — search users (LDAP + VNCdirectory)
   • POST /api/vncdirectory/2fa/enroll — generate TOTP secret
   • POST /api/vncdirectory/2fa/verify — verify TOTP code
   • GET /api/vncdirectory/2fa/status — check 2FA enrollment status
   • GET /api/vncdirectory/tags — directory contact tags
   • POST /api/vncdirectory/tags — create/update directory tags

3. New admin configuration page:

   • app/(main)/admin/vncdirectory/page.tsx — VNCdirectory settings panel
   • Sections:
     • Connection: VNCdirectory URL, API key, LDAP URI, bind credentials
     • SAML/IDP: Identity Provider URL (SimpleSAMLphp), SP certificate, issuer
     • Authentication: Toggle SAML login, toggle 2FA enforcement, OIDC settings
     • Directory sync: LDAP type (OpenLDAP/MS-AD), search base, attribute mapping
     • Federated apps: Configure SSO URLs for VNCtalk, VNCtask, VNCcontacts
   • Add to admin navigation sidebar

4. New stores/vncdirectory-store.ts — client-side config state

5. Extend existing auth:

   • Add SAML login as alternative to existing Basic/OAuth flows
   • Add VNCdirectory as identity source alongside Stalwart
   • Wire 2FA through VNCdirectory (currently uses Stalwart admin API)

Effort: 24h

P2.14 — Share Files by Email as Attachment

Docx: "share by email as attachment"

Implementation:

1. Extend components/files/file-browser.tsx — "Send as Email Attachment" action
2. Opens composer with selected files attached (reuse existing attachment upload in composer)
3. Effort: 4h

P2 Total: ~127h

---

Phase 3 — Security Hardening (Autonomous)

P3.1 — Feature Gate Server-Side Enforcement

Issue: Feature gates are UI-only. Disabled features remain accessible via direct API calls.

Fix: Add policy checks to API routes. For each feature-gated route, add isFeatureEnabled() check returning 403.

• Routes: app/api/smime/*, app/api/calendar-agenda/*, app/api/offline/*, app/api/plugins/* (plugin disabled)
• Effort: 4h

P3.2 — Unified Auth Error Interceptor

Issue: 401/403 errors silently swallowed in data fetches.

Fix: Create lib/auth-error-handler.ts — global fetch wrapper that detects 401 and triggers re-auth flow. Wire into JMAP client authenticatedFetch.

• Effort: 6h

P3.3 — Store-Level State Isolation on Account Switch

Issue: Manual clearAllStores() misses new fields and stores.

Fix: Define per-store snapshot(): Partial<S> and clear(): Partial<S> contract. Auto-discover registered stores via a registry.

• Effort: 8h

P3.4 — Push Event Bus Extraction

Issue: Email store is the push dispatch hub for 5+ stores.

Fix: Extract lib/push-event-bus.ts — stores subscribe to JMAP type names. Email store stops importing calendar/filter/task stores.

• Effort: 8h

P3 Total: ~26h

---

Phase 4 — Polish & Remaining HIGH Items

P4.1 — Offline Write Queue

Issue: No offline write capability. Cannot compose/send while offline.

Fix: Add replica_pending_ops table. Stage mutations offline, replay on connectivity return. Start with email send only, then extend.

• Effort: 16h

P4.2 — Identity Spoofing Protection

Issue: From override accepts arbitrary addresses.

Fix: Client-side validation — restrict fromOverrideEmail to domains matching user's identities.

• Effort: 2h

P4.3 — WebSocket Push for Electron

Issue: Browser WebSocket push permanently disabled.

Fix: Implement main-process WebSocket bridge in Electron via IPC. Renderer sends token, main process connects WS with auth header.

• Effort: 8h

P4.4 — Remaining MEDIUM audit findings

• Calendar: recurrence cap warning, prefix scheme unification, read-only calendar filter, bulk delete batching
• Contacts: cross-account move race, autocomplete indexing, import dedup
• Files: folder tree cache reuse, upload parallelism
• Search: toWildcardQuery quote handling, searchEmails AbortController
• Effort: ~20h

P4 Total: ~46h

---

Summary

Phase	Hours	Description
P1	32h	Critical + HIGH bug fixes (18 items)
P2	167h	Missing features from docx (14 features)
P3	26h	Security hardening (4 items)
P4	46h	Polish + remaining fixes (4 items)
Total	~271h

New Infrastructure Dependencies (P2)

• PostgreSQL database — resources + resources_bookings tables for VNCdirectory-backed resource management
• VNCdirectory — canonical source for resources + IDP identity provider (SAML 2.0, LDAP, 2FA/TOTP, directory tags)
• SimpleSAMLphp — SAML 2.0 Identity Provider (vncidp.dev.vnc.de) for web SSO
• OpenLDAP — LDAP directory for user/group queries and GAL (via ldapjs)
• Collabora server — collaboraBaseUrl admin config for online document editing
• VNCtalk API — /api/createnewmeeting endpoint for video meeting integration

Autonomy Level

• 100% autonomous — No further board decisions needed.
• Sync direction (VNCdirectory ↔ PostgreSQL): Assumed VNCdirectory → PostgreSQL (pull) for Phase 1. Can be swapped if VNCdirectory expects push updates.
• Code reuse: 12 areas from VNCmail-analysis Angular codebase (models, API patterns, business logic). Must be adapted from Angular DI/services to plain TS functions + React hooks.
• Repository access: brvncde-dotcom/vncmail-plus (target), brvncde-dotcom/VNCmail-analysis (reuse).

Deploy Flow

Per policy: P1 → deploy to dev → QA → fix → promote to main. Then P2 → dev → QA → main. Repeat for P3, P4.

Phase 1 — COMPLETED 2026-08-07

Shipped as v1.7.9. 17 of 18 fixes deployed to main. All 2527 tests pass (161 test files). One item deferred: P1.3 (C5 auth localStorage encryption) — requires custom Zustand persist adapter, planned for Phase 3.
