# Dependencies Checklist: Inventory Dependencies Graph
**Purpose**: Validate that Spec 042’s dependency-graph requirements are complete, unambiguous, and testable ("unit tests for English").
**Created**: 2026-01-07
**Feature**: `specs/042-inventory-dependencies-graph/spec.md`
**Note**: This checklist is generated by the `/speckit.checklist` command based on feature context and requirements.
## Requirement Completeness
- [x] CHK001 Are relationship types fully enumerated with definitions and at least one example per type? [Completeness, Spec §FR1]
- [x] CHK002 Are the minimum required fields for a dependency edge explicitly specified (e.g., source, target, type, directionality, timestamps, provenance)? [Gap, Spec §FR2]
- [x] CHK003 Are the categories of “other objects” (non-inventory foundations) explicitly enumerated and bounded (what is in-scope vs out-of-scope)? [Completeness, Spec §FR2]
- [x] CHK004 Are the identifiers/keys used to reference inventory items and foundational objects clearly specified (stable IDs vs display names)? [Gap, Plan §Dependencies]
- [x] CHK005 Are inbound and outbound edge queries both explicitly required for all supported relationship types (or are exceptions called out)? [Completeness, Spec §FR3]
- [x] CHK006 Are “missing prerequisites” criteria specified (what counts as missing, and how missing is detected)? [Completeness, Spec §Scenario 2, FR4]
- [x] CHK007 Are access control requirements defined beyond “access-controlled” (roles/permissions, tenant admin vs read-only, etc.)? [Gap, Spec §FR5]
## Requirement Clarity
- [x] CHK008 Is the meaning of “inbound” vs “outbound” relationships defined unambiguously (especially for asymmetric relations like “assigned to”)? [Clarity, Spec §Scenario 1, FR3]
- [x] CHK009 Are relationship labels (“uses”, “assigned to”, “scoped by”) defined as a taxonomy with consistent naming, directionality, and semantics? [Clarity, Spec §Scenario 1, FR1]
- [x] CHK010 Is “blast radius” translated into concrete, observable dependency-graph concepts (e.g., outbound edges only, both directions, depth)? [Ambiguity, Spec §Purpose]
- [x] CHK011 Is “prerequisite” defined precisely (e.g., hard prerequisite vs informational dependency; required vs optional)? [Ambiguity, Spec §Purpose, Scenario 2]
- [x] CHK012 Is the filter behavior for relationship types specified (single vs multi-select, default selection, empty selection meaning)? [Gap, Spec §Scenario 3]
- [x] CHK013 Are “safe warning” requirements specified with a format/fields and where they surface (sync logs, UI banner, audit log)? [Clarity, Spec §NFR2]
## Requirement Consistency
- [x] CHK014 Do “missing prerequisites” requirements align with “no separate deleted state in core inventory” without introducing contradictory states or terminology? [Consistency, Spec §FR4]
- [x] CHK015 Are the relationship examples in scenarios consistent with the relationship taxonomy required by FR1 (no scenario-only types)? [Consistency, Spec §Scenario 1, FR1]
- [x] CHK016 Do idempotency requirements (NFR1) align with determinism requirements (SC2) without ambiguity about ordering, deduplication, or normalization? [Consistency, Spec §NFR1, SC2]
- [x] CHK017 Are tenant-scoping requirements consistent across storage, querying, and UI exposure (no implied cross-tenant joins)? [Consistency, Spec §FR5, Out of Scope]
## Acceptance Criteria Quality
- [x] CHK018 Is SC1 (“under 2 minutes”) made measurable with a defined starting point, scope (single item, depth), and success signal (what the admin must be able to conclude)? [Measurability, Spec §SC1]
- [x] CHK019 Is SC2 (“deterministic output”) made measurable by defining what equivalence means (edge set equality, stable IDs, normalized relationship types)? [Measurability, Spec §SC2]
- [x] CHK020 Are acceptance criteria mapped to each Functional Requirement (FR1–FR5) so each requirement has an objective pass/fail definition? [Gap, Spec §Functional Requirements]
## Scenario Coverage
- [x] CHK021 Do scenarios cover both inbound and outbound viewing requirements explicitly (or is one direction implicitly assumed)? [Coverage, Spec §Scenario 1, FR3]
- [x] CHK022 Are scenarios defined for “no dependencies” (zero edges) and how that is communicated to the user? [Gap, Spec §User Scenarios & Testing]
- [x] CHK023 Are scenarios defined for “only missing prerequisites” (all targets missing) and how that impacts filtering or display? [Gap, Spec §Scenario 2]
- [x] CHK024 Are scenarios defined for mixed object types (inventory item → foundation object, foundation → inventory item) if both are supported? [Gap, Spec §FR2]
## Edge Case Coverage
- [x] CHK025 Are requirements specified for unknown/unsupported references beyond “record a safe warning” (e.g., whether an edge is skipped, recorded as unknown node, or preserved as raw ref)? [Coverage, Spec §NFR2]
- [x] CHK026 Are requirements defined for duplicate references within a single item (e.g., same target referenced multiple times) and expected edge deduplication rules? [Gap, Spec §NFR1, SC2]
- [x] CHK027 Are cyclic dependencies explicitly addressed (allow, detect, show, and/or bound traversal depth)? [Gap, Spec §Purpose]
- [x] CHK028 Are requirements defined for very large graphs (pagination, depth limits, maximum edges returned) given the stated “edge explosion” risk? [Gap, Plan §Risks]
## Non-Functional Requirements
- [x] CHK029 Does NFR1 define idempotency scope and mechanism expectations (e.g., uniqueness keys, replace-all vs upsert, run-scoped vs global)? [Clarity, Spec §NFR1]
- [x] CHK030 Does NFR2 define what constitutes “must not fail an inventory sync run” (soft-fail boundary, error severity classes, retries)? [Clarity, Spec §NFR2]
- [x] CHK031 Are performance requirements (latency, memory, query limits) specified for dependency extraction and for dependency viewing queries? [Gap, Plan §Risks]
- [x] CHK032 Are security/privacy requirements specified for what dependency data may expose (e.g., names/IDs of foundation objects) and who can see it? [Gap, Spec §FR5]
## Dependencies & Assumptions
- [x] CHK033 Are dependencies on Spec 040 identifiers and Spec 041 UI explicitly stated as hard requirements vs optional integration points? [Clarity, Plan §Dependencies]
- [x] CHK034 Are assumptions documented about which Intune object types contain references and the reference shapes expected (“heterogeneous reference shapes” risk)? [Assumption, Plan §Risks]
- [x] CHK035 Are assumptions documented about data freshness (when edges are extracted relative to inventory sync, and how stale edges are handled)? [Gap, Spec §NFR1]
## Ambiguities & Conflicts
- [x] CHK036 Is “foundation object not present in inventory” terminology consistent with “not requiring a deleted state” (missing vs absent vs excluded)? [Ambiguity, Spec §FR4]
- [x] CHK037 Is it explicitly defined whether cross-item dependencies are limited to within a policy type or across all inventory types? [Gap, Spec §Purpose, FR2]
- [x] CHK038 Is it clear whether relationship filtering applies only to edge types, or also to node/object types (inventory vs foundations)? [Gap, Spec §Scenario 3]
## Notes
- Check items off as completed: `[x]`
- Add findings inline under the relevant checklist item
- Each `/speckit.checklist` run creates a new checklist file

# PR Gate Checklist: Inventory Dependencies Graph
**Purpose**: PR-Review-Checklist zur Bewertung der Anforderungsqualität für Spec 042 (50% Daten/Pipeline, 50% Darstellung). Fokus: messbar, deterministisch reviewbar, scope-stabil durch „Enumerate now“.
**Created**: 2026-01-07
**Feature**: `specs/042-inventory-dependencies-graph/spec.md`
**Note**: This checklist is generated by the `/speckit.checklist` command based on feature context and requirements.
## Requirement Completeness
- [x] CHK001 Ist die Relationship-Taxonomie vollständig enumeriert (Set an Typen) und pro Typ mit Definition + Richtung + Beispiel beschrieben? [Completeness, Spec §FR1]
- [x] CHK002 Sind alle in-scope „foundational Intune objects“ explizit aufgelistet (Enumerate now) inkl. klarer Exclusions, um Scope zu binden? [Gap, Spec §FR2, Plan §Risks]
- [x] CHK003 Sind Mindestfelder einer Dependency-Edge als Requirement beschrieben (source, target, relationship_type, directionality, provenance/derived_from, timestamps/created_at, optional metadata)? [Gap, Spec §FR2]
- [x] CHK004 Ist klar spezifiziert, wie „inventory item“ eindeutig referenziert wird (stable identifier), und wie foundation objects referenziert werden (ID/uri/type tuple)? [Gap, Plan §Dependencies]
- [x] CHK005 Sind inbound UND outbound Abfragen als explizite Requirements beschrieben (inkl. erwarteter Sortierung/Limitierung oder bewusst „unspecified“)? [Completeness, Spec §FR3]
- [x] CHK006 Sind Missing-Prerequisites als eigene Requirement-Klasse beschrieben (Erkennung, Darstellung, und welche Daten minimal gezeigt werden dürfen)? [Completeness, Spec §FR4, Scenario 2]
- [x] CHK007 Ist Relationship-Type-Filtering vollständig spezifiziert (Scope, Default, Mehrfachauswahl ja/nein, Verhalten bei „none selected“)? [Completeness, Spec §Scenario 3]
- [x] CHK008 Sind Tenant-Scoping und Access Control Requirements konkretisiert (welche Rollen/Capabilities; Read vs View Details; ggf. audit expectations)? [Gap, Spec §FR5]
## Requirement Clarity
- [x] CHK009 Ist „inbound“ vs „outbound“ formal definiert pro Relationship-Type (nicht nur im Textbeispiel), um Interpretationsspielraum zu vermeiden? [Clarity, Spec §Scenario 1, FR3]
- [x] CHK010 Sind Relationship-Namen und Semantik konsistent (z.B. „assigned to“ ist eindeutig Richtung A→B) und nicht synonym/überlappend? [Clarity, Spec §FR1]
- [x] CHK011 Ist „blast radius“ in messbare Graph-Konzepte übersetzt (z.B. „outbound edges bis Tiefe N“, „both directions“, oder explizit „only direct neighbors“)? [Ambiguity, Spec §Purpose]
- [x] CHK012 Ist „prerequisite“ eindeutig definiert (hard vs informational, required vs optional) und ist diese Definition in Missing-Prerequisites konsistent wiederverwendet? [Ambiguity, Spec §Purpose, Scenario 2]
- [x] CHK013 Ist „safe warning“ (NFR2) klar operationalisiert: Inhalt/Felder, Severity, Persistenz, und wo es sichtbar wird (Run-Log vs UI vs Audit)? [Clarity, Spec §NFR2]
## Requirement Consistency
- [x] CHK014 Sind Scenario-Beispiele („uses“, „assigned to“, „scoped by“) vollständig Teil der FR1-Taxonomie (keine scenario-only Typen)? [Consistency, Spec §Scenario 1, FR1]
- [x] CHK015 Ist FR4 („missing prerequisites“) konsistent mit „ohne deleted state in core inventory“ beschrieben (kein implizites soft-delete/archived eingeführt)? [Consistency, Spec §FR4]
- [x] CHK016 Sind NFR1 (idempotent) und SC2 (deterministic output) konfliktfrei und eindeutig, was Gleichheit bedeutet (Edge-Set, Normalisierung, Sortierung)? [Consistency, Spec §NFR1, SC2]
- [x] CHK017 Ist der Tenant-Scope konsistent in Storage, Query und UI (keine impliziten cross-tenant Graphs; Out-of-scope ist explizit)? [Consistency, Spec §FR5, Out of Scope]
## Acceptance Criteria Quality
- [x] CHK018 Ist SC1 („unter 2 Minuten“) so definiert, dass Reviewer objektiv prüfen können, was „determine prerequisites and blast radius“ konkret bedeutet (Tiefe, Umfang, Informationsumfang)? [Measurability, Spec §SC1]
- [x] CHK019 Ist SC2 so messbar formuliert, dass deterministische Output-Gleichheit ohne Interpretationsspielraum prüfbar ist (z.B. canonical ordering + uniqueness rules)? [Measurability, Spec §SC2]
- [x] CHK020 Gibt es eine klare Traceability zwischen FR1–FR5 und Success Criteria (jedes FR hat mindestens ein objektives Akzeptanzkriterium oder ist bewusst als „non-testable“ markiert)? [Gap, Spec §Functional Requirements, Success Criteria]
## Scenario Coverage
- [x] CHK021 Deckt die Spec explizit den Zero-State ab („no edges“ / „no deps“), inkl. erwarteter UI-Messaging-Requirement? [Gap, Spec §User Scenarios & Testing]
- [x] CHK022 Deckt die Spec explizit Mixed-Targets ab (Inventory→Foundation, Inventory→Inventory) und ob Foundation→Inventory als inbound dargestellt werden soll? [Gap, Spec §FR2, FR3]
- [x] CHK023 Gibt es definierte Requirements für „only missing prerequisites“ (alle Targets missing) und wie Filter/Display damit umgehen? [Gap, Spec §Scenario 2]
## Edge Case Coverage
- [x] CHK024 Sind Unknown/Unsupported References (NFR2) vollständig als Requirements abgedeckt: ob Edge erzeugt wird, ob Node „unknown“ erlaubt ist, ob raw reference gespeichert wird? [Coverage, Spec §NFR2]
- [x] CHK025 Sind Duplicate References innerhalb eines Items geregelt (Dedup-Key, Merge Rules), um NFR1/SC2 deterministisch einzuhalten? [Gap, Spec §NFR1, SC2]
- [x] CHK026 Sind zyklische Dependencies als Requirement adressiert (Erkennung/Handling/Traversal-Limits), damit „blast radius“ nicht unendlich wird? [Gap, Spec §Purpose, Plan §Risks]
- [x] CHK027 Sind Grenzen für Edge-Explosion als Requirements spezifiziert (Limits, pagination, depth caps, server-side constraints), nicht nur als Risiko erwähnt? [Gap, Plan §Risks]
## Non-Functional Requirements
- [x] CHK028 Ist Idempotenz (NFR1) präzisiert: Scope (per-run vs global), Unique Keys, Upsert vs Replace-All, und ob Deletions/Orphan-Edges geregelt sind? [Clarity, Spec §NFR1]
- [x] CHK029 Ist „must not fail an inventory sync run“ präzisiert: welche Fehler sind soft-fail, welche sind hard-fail, und wie wird das für Reviewer nachvollziehbar? [Clarity, Spec §NFR2]
- [x] CHK030 Sind Performance-/Skalierungsanforderungen spezifiziert (UI Query Latency, max edges returned, extraction time budget) statt nur „Risiko“? [Gap, Plan §Risks]
- [x] CHK031 Sind Security/Privacy-Anforderungen spezifiziert, welche foundation-object Daten sichtbar sein dürfen (IDs vs Names) und ob das tenant- & permission-scoped ist? [Gap, Spec §FR5]
## Dependencies & Assumptions
- [x] CHK032 Sind Abhängigkeiten zu Spec 040 (stable identifiers) und Spec 041 (UI navigation/detail pages) als Requirements eindeutig dokumentiert (hard requirement vs optional)? [Clarity, Plan §Dependencies]
- [x] CHK033 Sind Annahmen über heterogene Reference-Shapes explizit dokumentiert und ist klar, wie neue Shapes in Scope aufgenommen werden (Change control / taxonomy update)? [Assumption, Plan §Risks]
- [x] CHK034 Ist explizit dokumentiert, wann Edges extrahiert werden (im sync run vs post-processing), und wie Staleness/Refresh geregelt ist? [Gap, Spec §NFR1]
## Ambiguities & Conflicts
- [x] CHK035 Sind Begriffe „missing“, „not present“, „excluded“, „out-of-scope“ sauber definiert und konsistent verwendet (kein Vermischen von Datenzustand und Scope)? [Ambiguity, Spec §FR4, Out of Scope]
- [x] CHK036 Ist klar, ob Filtering nur Relationship-Types betrifft oder auch Node-Types (Inventory vs Foundation) und ob beides kombinierbar sein soll? [Gap, Spec §Scenario 3]
## Notes
- Check items off as completed: `[x]`
- Findings als kurze Stichpunkte direkt unter dem jeweiligen Item ergänzen
- Jede `/speckit.checklist` Ausführung erzeugt eine neue Datei (kein Overwrite)

## Deliverables ## Deliverables
- Relationship taxonomy - Relationship taxonomy (enum + metadata)
- Persisted dependency edges - Persisted dependency edges (`inventory_links` table)
- Query and rendering in UI - Extraction pipeline (integrated into inventory sync)
- Query service methods (inbound/outbound)

## Risks ## Risks
- Heterogeneous reference shapes across policy types - Heterogeneous reference shapes across policy types → **Mitigation**: Normalize references early; unsupported shapes → soft warning, skip edge creation
- Edge explosion for large tenants - Edge explosion for large tenants → **Mitigation**: Hard limit ≤50 edges per item per direction (enforced at extraction); pagination UI for future
---
## 1. Extraction Pipeline
### Timing & Integration
- **When**: Dependencies extracted **during inventory sync run** (not on-demand)
- **Hook**: After `InventorySyncService` creates/updates `InventoryItem`, call `DependencyExtractionService`
- **Idempotency**: Each sync run reconciles edges for synced items (upsert based on unique key)
### Inputs
1. **InventoryItem** (`raw`, `meta`, `resource_type`, `external_id`)
2. **Assignments payload** (if available): AAD Group IDs
3. **Scope tags** (from item `meta->scopeTags` or raw payload)
4. **Device categories** (from conditional logic in raw payload, if applicable)
### Extraction Logic
```php
DependencyExtractionService::extractForItem(InventoryItem $item): array
```
- Parse `$item->raw` and `$item->meta` for known reference shapes
- For each reference:
- Normalize to `{type, external_id, display_name?}`
- Determine `relationship_type` (assigned_to, scoped_by, targets, depends_on)
- Resolve target:
- If `InventoryItem` exists with matching `external_id` → `target_type='inventory_item'`
- If foundation object (AAD Group, Scope Tag, Device Category) → `target_type='foundation_object'`
- If unresolvable → `target_type='missing'`, `target_id=null`, store `metadata.last_known_name`
- Create/update edge
### Error & Warning Logic
- **Unsupported reference shape**: Log warning (`info` severity), record in sync run metadata, skip edge creation
- **Low confidence**: If reference parsing heuristic uncertain, create edge with `metadata.confidence='low'`
- **Unresolved target**: Create edge with `target_type='missing'` (not an error)
- **All targets missing**: Extraction still emits `missing` edges; UI must handle zero resolvable targets without error
### Hard Limits
- **Max 50 edges per item per direction** (outbound/inbound)
- Enforced at extraction: sort by priority (assigned_to > scoped_by > targets > depends_on), keep top 50, log truncation warning
---
## 2. Storage & Upsert Details
### Schema: `inventory_links` Table
```php
Schema::create('inventory_links', function (Blueprint $table) {
$table->id();
$table->foreignId('tenant_id')->constrained()->cascadeOnDelete();
$table->string('source_type'); // 'inventory_item', 'foundation_object'
$table->uuid('source_id'); // InventoryItem.id or foundation stable ID
$table->string('target_type'); // 'inventory_item', 'foundation_object', 'missing'
$table->uuid('target_id')->nullable(); // null if target_type='missing'
$table->string('relationship_type'); // 'assigned_to', 'scoped_by', etc.
$table->jsonb('metadata')->nullable(); // {last_known_name, raw_ref, confidence, ...}
$table->timestamps();
// Unique key (idempotency)
$table->unique([
'tenant_id',
'source_type',
'source_id',
'target_type',
'target_id',
'relationship_type'
], 'inventory_links_unique');
$table->index(['tenant_id', 'source_type', 'source_id']);
$table->index(['tenant_id', 'target_type', 'target_id']);
});
```
### Upsert Strategy
- **On extraction**: `InventoryLink::upsert($edges, uniqueBy: ['tenant_id', 'source_type', 'source_id', 'target_type', 'target_id', 'relationship_type'], update: ['metadata', 'updated_at'])`
- **On item deletion**: Edges **NOT** auto-deleted (orphan cleanup is manual or scheduled job)
- **On re-run**: Existing edges updated (`updated_at` bumped), new edges created
### Hard Limit Enforcement
- Extraction service limits to 50 edges per direction before upserting
- Query methods (`getOutboundEdges`, `getInboundEdges`) have default `limit=50` parameter
---
## 3. UI Components (Filament)
### Location
- **InventoryItemResource → ViewInventoryItem page**
- New section: "Dependencies" (below "Details" section)
### Component Structure
```php
// app/Filament/Resources/InventoryItemResource.php (or dedicated Infolist)
Section::make('Dependencies')
->schema([
// Filter: Inbound / Outbound / All (default: All)
Forms\Components\Select::make('direction')
->options(['all' => 'All', 'inbound' => 'Inbound', 'outbound' => 'Outbound'])
->default('all')
->live(),
// Edges table (or custom Blade component)
ViewEntry::make('edges')
->view('filament.components.dependency-edges')
->state(fn (InventoryItem $record) =>
DependencyService::getEdges($record, request('direction', 'all'))
),
])
```
### Blade View: `resources/views/filament/components/dependency-edges.blade.php`
- **Zero-state**: If `$edges->isEmpty()`: "No dependencies found"
- **Edge rendering**:
- Group by `relationship_type` (collapsible groups or headings)
- Each edge: icon + target name + link (if resolvable) + "Missing" red badge (if target_type='missing') + tooltip (metadata.last_known_name)
- **Performance**: Load edges synchronously (≤50 per direction, fast query with indexes)
- **Privacy**: If display name unavailable, render masked identifier (e.g., `ID: abcd12…`), no cross-tenant lookups
### Filter Behavior
- Single-select dropdown (not multi-select)
- Default: "All" (both inbound + outbound shown)
- Empty/null selection → treated as "All"
---
## 4. Tests
### Unit Tests
- `DependencyExtractionServiceTest.php`:
- `test_normalizes_references_deterministically()`: same raw input → same edges (order-independent)
- `test_respects_unique_key()`: re-extraction → no duplicate edges
- `test_handles_unsupported_references()`: logs warning, skips edge
- `InventoryLinkTest.php`:
- `test_unique_constraint_enforced()`: duplicate insert → exception or upsert
- `test_tenant_scoping()`: edges filtered by tenant_id
### Feature Tests
- `DependencyExtractionFeatureTest.php`:
- `test_extraction_creates_expected_edges()`: fixture item → assert edges created (assigned_to, scoped_by)
- `test_extraction_marks_missing_targets()`: item references non-existent group → edge with target_type='missing'
- `test_extraction_respects_50_edge_limit()`: item with 60 refs → only 50 edges created
- `test_only_missing_prerequisites_scenario()`: item whose all targets are unresolved → only `missing` edges, UI renders badges
- `DependencyQueryServiceTest.php`:
- `test_get_outbound_edges_filters_by_tenant()`: cannot see other tenant's edges
- `test_get_inbound_edges_returns_correct_direction()`
### UI Smoke Tests
- `InventoryItemDependenciesTest.php`:
- `test_dependencies_section_renders()`: view page → see "Dependencies" section
- `test_filter_works()`: select "Inbound" → only inbound edges shown
- `test_zero_state_shown()`: item with no edges → "No dependencies found"
- `test_missing_badge_shown()`: edge with target_type='missing' → red badge visible
- `test_masks_identifier_when_name_unavailable()`: foundation object without display name → masked ID shown
### Security Tests
- `DependencyTenantIsolationTest.php`:
- `test_cannot_see_other_tenant_edges()`: tenant A user → cannot query tenant B edges
- `test_edges_scoped_by_tenant()`: all query methods enforce tenant_id filter
- `test_no_cross_tenant_enrichment()`: service never fetches/display names across tenants

Represent and surface dependency relationships between inventory items and foundational Intune objects so admins can understand blast radius and prerequisites. Represent and surface dependency relationships between inventory items and foundational Intune objects so admins can understand blast radius and prerequisites.
**Definitions**:
- **Blast radius**: All resources directly or transitively affected by a change to a given item (outbound edges up to depth 2).
- **Prerequisite**: A hard dependency required for an item to function; missing prerequisites are explicitly surfaced.
- **Inbound edge**: A relationship pointing TO this item (e.g., "Policy A is assigned to Group X" → Group X has inbound edge from Policy A).
- **Outbound edge**: A relationship pointing FROM this item (e.g., "Policy A is scoped by ScopeTag Y" → Policy A has outbound edge to ScopeTag Y).

- When the user views dependencies - When the user views dependencies
- Then missing prerequisites are clearly indicated - Then missing prerequisites are clearly indicated (red badge, "Missing" label, tooltip with last-known displayName if available)
### Scenario 3: Filter dependencies by relationship type ### Scenario 3: Zero dependencies

- When the user opens dependencies view
- Then a "No dependencies found" message is shown

- Given multiple relationship types exist - Given multiple relationship types exist
- When the user filters by relationship type - When the user filters by relationship type (single-select dropdown, default: "All")
- Then only matching edges are shown - Then only matching edges are shown (empty selection = all edges visible)
### Scenario 5: Only missing prerequisites
- Given an item where all referenced targets are unresolved (no matching inventory or foundation objects)
- When the user opens the dependencies view and selects "Outbound" or "All"
- Then all shown edges are annotated as "Missing" with a red badge and tooltip; filtering still works and zero resolvable targets do not error
## Functional Requirements ## Functional Requirements
- FR1: Define a normalized set of relationship types. - **FR1: Relationship taxonomy**
- FR2: Store dependency edges between inventory items and other objects (including non-inventory foundations when applicable). Define a normalized set of relationship types covering inventory→inventory and inventory→foundation edges.
- FR3: Allow querying inbound/outbound edges for a given item. Supported types (MVP):
- FR4: Show missing prerequisites without requiring a separate “deleted” state in core inventory. - `assigned_to` (Policy → AAD Group)
- FR5: All dependency data is tenant-scoped and access-controlled. - `scoped_by` (Policy → Scope Tag)
- `targets` (Update Policy → Device Category, conditional logic)
- `depends_on` (Generic prerequisite, e.g., Compliance Policy referenced by Conditional Access)
Each type has:
- `name` (string, e.g., "assigned_to")
- `display_label` (string, e.g., "Assigned to")
- `directionality` (enum: `outbound`, `inbound`, `bidirectional`)
- `description` (brief explanation)
- **FR2: Dependency edge storage**
Store edges in an `inventory_links` table with fields:
- `id` (PK)
- `tenant_id` (FK, indexed)
- `source_type` (string: `inventory_item`, `foundation_object`)
- `source_id` (UUID or stable ref)
- `target_type` (string: `inventory_item`, `foundation_object`, `missing`)
- `target_id` (UUID or stable ref, nullable if missing)
- `relationship_type` (FK to taxonomy or enum)
- `metadata` (JSONB, optional: last_known_name, raw_ref, etc.)
- `created_at`, `updated_at`
**In-scope foundation object types (MVP)**:
- AAD Groups (`aad_group`)
- Scope Tags (`scope_tag`)
- Device Categories (`device_category`)
**Out-of-scope foundation types** (for this iteration): Conditional Access Policies, Compliance Policies as foundation nodes (only as inventory items).
- **FR3: Query inbound/outbound edges**
Provide service methods:
- `getOutboundEdges(item_id, relationship_type?, limit=50)` → returns edges where item is source
- `getInboundEdges(item_id, relationship_type?, limit=50)` → returns edges where item is target
Both return paginated, ordered by `created_at DESC`.
- **FR4: Missing prerequisites**
When a target reference cannot be resolved:
- Create edge with `target_type='missing'`, `target_id=null`
- Store `metadata.last_known_name` and `metadata.raw_ref` if available
- UI displays "Missing" badge + tooltip
No separate "deleted" or "archived" state in core inventory; missing is purely an edge property.
- **FR5: Tenant scoping and access control**
- All edges filtered by `tenant_id` matching `Tenant::current()`
- Read access: any authenticated tenant user
- No cross-tenant queries allowed (enforced at query builder level)
## Non-Functional Requirements ## Non-Functional Requirements
- NFR1: Dependency extraction must be idempotent (re-runnable without duplicating edges). - **NFR1: Idempotency**
- NFR2: Dependency extraction must not fail an inventory sync run if an unknown/unsupported reference is encountered; it should record a safe warning. Dependency extraction must be idempotent:
- Unique key: `(tenant_id, source_type, source_id, target_type, target_id, relationship_type)`
- On re-run: upsert (update `updated_at`, replace `metadata` if changed)
- Orphan edges (source/target no longer in inventory) are NOT auto-deleted; cleanup is manual or scheduled separately
- **NFR2: Graceful unknown-reference handling**
If an unknown/unsupported reference shape is encountered:
- Log warning with severity `info` (not `error`)
- Do NOT create an edge for unsupported types
- Record warning in sync run metadata: `{type: 'unsupported_reference', policy_id, raw_ref, reason}`
- Sync run continues without failure
## Graph Traversal & Cycles
- UI blast radius view is limited to depth ≤ 2 (direct neighbors and their neighbors).
- Traversal uses visited-node tracking to prevent revisiting nodes (cycle break); cycles are implicitly handled by not re-visiting.
- No special UI cycle annotation in MVP; future work may visualize cycles explicitly.
## Success Criteria ## Success Criteria
- SC1: Admins can determine prerequisites and blast radius for an item in under 2 minutes. - **SC1: Blast radius determination**
- SC2: For supported relationship types, dependency edges are consistent across re-runs (deterministic output). Admins can determine prerequisites (inbound edges) and blast radius (outbound edges, depth ≤2) for any item in under 2 minutes:
- Measured from: clicking "View Dependencies" on an item detail page
- To: able to answer "What would break if I delete this?" and "What does this depend on?"
- Acceptance: <2s page load, ≤50 edges per direction shown initially, clear visual grouping by relationship type
- **SC2: Deterministic output**
For supported relationship types, dependency edges are consistent across re-runs:
- Given identical inventory state (same items, same Graph API responses)
- Edge set equality: same `(source, target, relationship_type)` tuples (order-independent)
- Acceptance: automated test re-runs extraction twice on fixed test data; assert edge sets match (ignoring `updated_at`)
## Security & Privacy
- All data is tenant-scoped; no cross-tenant queries or joins.
- Foundation object visibility:
- Display name shown only if available from tenant-authorized sources (inventory metadata or prior sync payloads).
- If not available, show a masked or abbreviated identifier (e.g., first 6 characters of ID) with no external lookup.
- Stored metadata for edges must avoid PII beyond display names surfaced by Graph within the tenant; raw references may be stored but not enriched from outside the tenant scope.
## Traceability
- FR1 (taxonomy) → SC2 (deterministic types), tests: unit taxonomy load/assert
- FR2 (storage) → SC2 (edge equality), tests: feature upsert and equality
- FR3 (queries) → SC1 (answer in <2 min), tests: service returns inbound/outbound within limits
- FR4 (missing) → SC1 (clear prerequisite view), tests: feature missing badge/tooltip
- FR5 (tenant scope) → SC1/SC2 (correct data, deterministic set), tests: tenant isolation
