ahmido da18d3cb14 feat/042-inventory-dependencies-graph (#50)
Dieses PR liefert den Inventory Dependencies Graph end-to-end: Abhängigkeiten (Edges) werden aus Inventory-Sync-Daten extrahiert, tenant-sicher gespeichert und in der Inventory Item Detailansicht angezeigt.

Ziel: Admins können Prerequisites + Blast Radius (direct) schnell erkennen, ohne Snapshot/Restore anzufassen.

Was ist drin?

Dependency Graph (Edges)
	•	inventory_links Schema + Indizes + idempotentes Upsert (Unique Key)
	•	Relationship Types (u.a.):
	•	assigned_to_include, assigned_to_exclude
	•	uses_assignment_filter
	•	scoped_by_scope_tag
	•	UI: Inventory Item → Dependencies Section
	•	Direction Filter: All / Inbound / Outbound
	•	Relationship Filter: All + spezifische Relationship Types
	•	Missing-Badge + sicheres Tooltip (safe subset)

Safety / Observability
	•	Unknown/unsupported Shapes erzeugen keine Edges, sondern:
	•	Warning in InventorySyncRun.error_context.warnings[]
	•	optional info-log (ohne Secrets)
	•	Limit-only Semantik (MVP): bis zu 50 Edges pro Richtung (max 100 bei “All”)
	•	Blast Radius in MVP = direct only (kein depth>1 traversal)

Name Resolution (lokal, ohne Entra Calls)
	•	Resolver/DTO Layer für deterministische Labels (kein “Unknown” mehr)
	•	Auflösung aus lokaler DB nur für Foundations, wenn vorhanden:
	•	scope_tag → roleScopeTag
	•	assignment_filter → assignmentFilter
	•	aad_group bleibt bewusst external ref: “Group (external): …” (keine Graph/Entra Lookups im UI)
	•	Zentraler FoundationTypeMap als Source-of-Truth (keine Hardcodings)

⸻

Out of Scope / Follow-up
	•	Entra Group Name Resolution (braucht eigenes “Group Inventory” Modul + Permissions)
	•	Foundations als Inventory Items / Coverage Tab (Scope Tags / Assignment Filters sichtbar & syncbar)
→ folgt als separater PR (Inventory Core/UI), damit 042 sauber “Edges-only” bleibt.

⸻

Tests / Verifikation
	•	Targeted Pest Tests (Unit + Feature + UI smoke) für:
	•	deterministische Edge-Erzeugung + idempotent upsert
	•	tenant isolation (UI/Query)
	•	warnings auf Run Record
	•	resolver/name rendering + links (wo möglich)
	•	pint --dirty ausgeführt

⸻

Manual QA (UI)
	1.	Inventory Sync Run mit include_dependencies=true starten
	2.	Inventory Item öffnen → Dependencies prüfen:
	•	include/exclude + filter + scoped_by sichtbar (wenn vorhanden)
	•	Relationship/Direction Filter funktionieren
	•	keine “Unknown” Labels mehr, sondern deterministische Labels

# Data Model — Inventory Dependencies Graph (042)
## Entities
### InventoryItem
Existing entity (Spec 040).
Key fields used by this feature:
- `tenant_id` (FK)
- `external_id` (string; stable identifier used as edge endpoint)
- `policy_type` (string)
- `display_name` (nullable string)
- `meta_jsonb` (array/jsonb; safe subset)
### InventorySyncRun
Existing entity used for observability of sync operations.
Key fields used by this feature:
- `tenant_id`
- `selection_hash`
- `selection_payload` (array)
- `status` (running/success/partial/failed/skipped)
- `had_errors` (bool)
- `error_codes` (array)
- `error_context` (array)
For MVP warnings persistence:
- `error_context.warnings[]` (array of warning objects)
- Warning object shape (stable): `{type: 'unsupported_reference', policy_id, raw_ref, reason}`
### InventoryLink
Dependency edge storage.
Fields:
- `tenant_id`
- `source_type` (string; MVP uses `inventory_item`)
- `source_id` (string; stores `InventoryItem.external_id`)
- `target_type` (string; `inventory_item` | `foundation_object` | `missing`)
- `target_id` (nullable string; null when missing)
- `relationship_type` (string; values from RelationshipType enum)
- `metadata` (jsonb)
- timestamps
Unique key (idempotency):
- `(tenant_id, source_type, source_id, target_type, target_id, relationship_type)`
#### InventoryLink.metadata
Common keys:
- `last_known_name` (nullable string)
- `raw_ref` (mixed/array; only when safe)
Required when `target_type='foundation_object'`:
- `foundation_type` (string enum-like): `aad_group` | `scope_tag` | `device_category` | `assignment_filter`
Additional metadata (when applicable):
- `filter_mode` (string enum-like): `include` | `exclude` (for `foundation_type='assignment_filter'`)
## Enums
### RelationshipType
- `assigned_to`
- `assigned_to_include`
- `assigned_to_exclude`
- `uses_assignment_filter`
- `scoped_by`
- `targets`
- `depends_on`
## Relationships
- InventoryItem (source) has many outbound InventoryLinks via `source_id` + `tenant_id`.
- InventoryItem (target) has many inbound InventoryLinks via `target_id` + `tenant_id` where `target_type='inventory_item'`.
## Constraints / Limits
- Query: limit-only, ordered by `created_at DESC`.
- UI: max 50 per direction (<=100 combined).
- Extraction: max 50 outbound edges per item; unknown shapes are warning-only.
