Context Resolvers

What are Context Resolvers?

Context Resolvers populate Request.Context.* during planning using read-only provider capabilities.

They run during plan build
They execute before step Condition evaluation
They enrich the request with stable, pre-resolved associated data
They are strictly validated and fail fast on invalid configuration

Context Resolvers allow Conditions, Preconditions, and Template Substitution to rely on data that was resolved once during planning.

⚠️ Context Resolvers vs Templates vs Conditions vs Preconditions

Do not confuse these concepts

Context Resolvers populate Request.Context.* during planning.
Template Substitution consumes Request.* values to build strings.
Conditions decide step applicability during planning (NotApplicable).
Preconditions guard step behavior during execution (Blocked / Fail / Continue).

Context Namespace Structure

Each resolver writes its output to a provider/auth-scoped source-of-truth path and updates engine-defined Views.

Source of truth (scoped path)

Request.Context.Providers.<ProviderAlias>.<AuthSessionKey>.<CapabilitySubPath>

<ProviderAlias> — the provider alias from With.Provider (or the auto-selected alias).
<AuthSessionKey> — Default when With.AuthSessionName is not specified; otherwise the exact name.
<CapabilitySubPath> — the capability-defined sub-path:
- IdLE.Entitlement.List → Identity.Entitlements
- IdLE.Identity.Read → Identity.Profile

Examples:

Request.Context.Providers.Entra.Default.Identity.Entitlements
Request.Context.Providers.Entra.CorpAdmin.Identity.Entitlements
Request.Context.Providers.AD.Default.Identity.Entitlements
Request.Context.Providers.Identity.Default.Identity.Profile

Views (engine-defined aggregations)

For capabilities with defined view semantics, the engine builds deterministic Views after each resolver:

View	Path	Description
All providers, all sessions	`Request.Context.Views.<CapabilitySubPath>`	Aggregated from all providers and all auth sessions.
One provider, all sessions	`Request.Context.Views.Providers.<ProviderAlias>.<CapabilitySubPath>`	Aggregated for one provider across all its auth sessions.
All providers, one session	`Request.Context.Views.Sessions.<AuthSessionKey>.<CapabilitySubPath>`	Aggregated across all providers that ran with the given auth session key.
One provider, one session	`Request.Context.Views.Providers.<ProviderAlias>.Sessions.<AuthSessionKey>.<CapabilitySubPath>`	Exactly one provider + one auth session.

IdLE.Entitlement.List — list merge (all entries preserved across all contributing providers/sessions):

Request.Context.Views.Identity.Entitlements — all providers, all sessions merged
Request.Context.Views.Providers.Entra.Identity.Entitlements — Entra only, all sessions
Request.Context.Views.Sessions.Default.Identity.Entitlements — all providers, Default session only
Request.Context.Views.Providers.Entra.Sessions.CorpAdmin.Identity.Entitlements — Entra + CorpAdmin session only

IdLE.Identity.Read — single-object view (last writer wins with deterministic sort order: provider alias asc, then auth key asc):

Request.Context.Views.Identity.Profile — last profile across all providers and sessions
Request.Context.Views.Providers.Entra.Identity.Profile — last profile from Entra (across all sessions)
Request.Context.Views.Sessions.Default.Identity.Profile — last profile from any provider using the Default session
Request.Context.Views.Providers.Entra.Sessions.CorpAdmin.Identity.Profile — exact profile for Entra + CorpAdmin

All profile and entitlement entries include SourceProvider and SourceAuthSessionName metadata for auditing.

Profile Views are convenience views, not mirrors

Profile Views are deterministic convenience aggregations, not direct copies of a specific provider result.
When multiple IdLE.Identity.Read resolvers run (different providers or auth sessions), the aggregated Views reflect the last profile after a stable alphabetical sort (first by provider alias ascending, then by auth session key ascending).

This means Request.Context.Views.Identity.Profile may differ from (or be a different object than) Request.Context.Providers.<ProviderAlias>.<AuthKey>.Identity.Profile — that is by design.

When to use which path:

Use Request.Context.Views.* when you do not care which provider returned the profile (e.g., "does any profile exist").
Use Request.Context.Providers.<ProviderAlias>.<AuthKey>.Identity.Profile when you need the exact result from a specific provider and session.

Step-relative Current alias (execution-time only)

During precondition evaluation (execution time), you may use Request.Context.Current.* to refer to the scoped context of the step's own provider and auth session:

Request.Context.Current.<CapabilitySubPath>

Resolved from Step.With.Provider + Step.With.AuthSessionName (or Default).

Restriction: Request.Context.Current.* MUST NOT be used in plan-time Condition fields. It is only valid in Precondition and other execution-time evaluations.

Full Example

@{
  Name           = 'Joiner - Context Resolver Demo'
  LifecycleEvent = 'Joiner'

  ContextResolvers = @(
    @{
      Capability = 'IdLE.Identity.Read'
      With = @{
        IdentityKey     = '{{Request.IdentityKeys.EmployeeId}}'
        Provider        = 'Identity'        # optional; auto-selected if omitted
        AuthSessionName = 'Tier0'           # optional; requires AuthSessionBroker in Providers
      }
      # Writes to: Request.Context.Providers.Identity.Tier0.Identity.Profile
    }

    @{
      Capability = 'IdLE.Entitlement.List'
      With = @{
        IdentityKey = '{{Request.IdentityKeys.EmployeeId}}'
        Provider    = 'Identity'
      }
      # Writes to: Request.Context.Providers.Identity.Default.Identity.Entitlements
      # View:      Request.Context.Views.Identity.Entitlements
    }
  )

  Steps = @(

    @{
      Name = 'Disable only if identity exists'
      Type = 'IdLE.Step.DisableIdentity'

      # Reference the scoped source-of-truth path:
      Condition = @{
        Exists = 'Request.Context.Providers.Identity.Tier0.Identity.Profile'
      }
    }

    @{
      Name = 'Emit audit event'
      Type = 'IdLE.Step.EmitEvent'

      With = @{
        Message = 'Disabled identity {{Request.Context.Providers.Identity.Tier0.Identity.Profile.Attributes.DisplayName}}'
      }
    }
  )
}

Keys

Capability (required)
A permitted read-only capability.

With (hashtable, optional — required in practice, as capabilities need at least IdentityKey)
Inputs required by the capability. Template substitution is supported.

`With` key	Type	Required	Description
`IdentityKey`	`string`	Per capability	Required by `IdLE.Identity.Read` and `IdLE.Entitlement.List`.
`Provider`	`string`	No	Provider alias. If omitted, IdLE auto-selects a provider advertising the capability. Ambiguity (multiple providers matching) is a fail-fast error. Also used to determine `<ProviderAlias>` in the scoped path.
`AuthSessionName`	`string`	No	Named auth session key. Becomes `<AuthSessionKey>` in the scoped path. If omitted, `Default` is used. Requires an `AuthSessionBroker` entry in `Providers`. Must be a valid path segment (no dots).
`AuthSessionOptions`	`hashtable`	No	Options passed to `AuthSessionBroker.AcquireAuthSession`. Must be a hashtable. ScriptBlocks are rejected.

Common Patterns

Use the global View for "don't care about source"

The most common pattern for entitlements: check or reference entitlements regardless of which provider returned them:

# In a Condition:
Condition = @{ Exists = 'Request.Context.Views.Identity.Entitlements' }

# In a NotContains check (member-access enumeration across all providers):
Condition = @{
  NotContains = @{
    Path  = 'Request.Context.Views.Identity.Entitlements.Id'
    Value = 'CN=BreakGlass-Users,OU=Groups,DC=example,DC=com'
  }
}

Use scoped paths for provider-specific checks

When you need to check entitlements only from a specific provider:

Condition = @{
  Exists = 'Request.Context.Providers.Entra.Default.Identity.Entitlements'
}

Multi-provider entitlements (no collision)

Use the same capability for multiple providers. Results are kept isolated:

ContextResolvers = @(
  @{ Capability = 'IdLE.Entitlement.List'; With = @{ IdentityKey = 'user1'; Provider = 'Entra' } }
  @{ Capability = 'IdLE.Entitlement.List'; With = @{ IdentityKey = 'user1'; Provider = 'AD' } }
)
# Result: Providers.Entra.Default.Identity.Entitlements (Entra-specific)
#         Providers.AD.Default.Identity.Entitlements     (AD-specific)
#         Views.Identity.Entitlements                     (merged, both providers)

Step-relative precondition using Current

Use Request.Context.Current.* in a step's Precondition to check the scoped context for that step's own provider without hard-coding the provider alias:

@{
  Name         = 'EnsureEntitlement'
  Type         = 'IdLE.Step.EnsureEntitlement'
  With         = @{
    Provider    = 'Entra'
    IdentityKey = '{{Request.IdentityKeys.Id}}'
    Entitlement = @{ Kind = 'Group'; Id = 'sg-all-staff' }
    State       = 'Present'
  }
  # Current resolves to Providers.Entra.Default at execution time (derived from With.Provider)
  Precondition = @{ Exists = 'Request.Context.Current.Identity.Entitlements' }
}

Guard destructive steps

Only perform destructive actions if identity exists:

Condition = @{
    Exists = 'Request.Context.Providers.Identity.Default.Identity.Profile'
}

Entitlement Source Metadata

Every entitlement entry in a resolved list includes source metadata automatically added by the engine:

Property	Description
`SourceProvider`	The provider alias that returned this entitlement.
`SourceAuthSessionName`	The auth session key used (`Default` if no session was specified).

This enables auditing and per-source filtering when working with merged views.

Troubleshooting

Inspecting resolved context data

When working with complex resolver outputs (entitlements, profiles), inspect the plan object directly after calling New-IdlePlan. This is the recommended approach during authoring and debugging. Do not rely on template substitution for this purpose — template substitution only resolves scalar values and cannot serialize whole objects or lists.

Inspect the complete context tree:

# Assume you have already built a plan:
# $request   = ...     # build a valid IdLE request
# $providers = @{ ... } # configured provider map
# $plan = New-IdlePlan -WorkflowPath ./workflow.psd1 -Request $request -Providers $providers

# Full context structure (use Depth 8 for deeply nested Views)
$plan.Request.Context | ConvertTo-Json -Depth 8

# Scoped source-of-truth namespace only
$plan.Request.Context.Providers | ConvertTo-Json -Depth 8

# Engine-defined Views only
$plan.Request.Context.Views | ConvertTo-Json -Depth 8

Inspect a specific scoped path:

# Entitlements from one provider
$plan.Request.Context.Providers.Identity.Default.Identity.Entitlements | ConvertTo-Json -Depth 2

# Profile from one provider
$plan.Request.Context.Providers.Identity.Default.Identity.Profile | ConvertTo-Json -Depth 4

# Global merged View
$plan.Request.Context.Views.Identity.Entitlements | ConvertTo-Json -Depth 2

Quick tabular view:

$plan.Request.Context.Views.Identity.Entitlements | Format-Table -AutoSize

Inspect individual properties to understand the path structure:

# Check available properties on the profile object
$plan.Request.Context.Providers.Identity.Default.Identity.Profile | Get-Member

# Access profile attributes — attributes are nested under the Attributes key
$plan.Request.Context.Providers.Identity.Default.Identity.Profile.Attributes

# Check a specific attribute
$plan.Request.Context.Providers.Identity.Default.Identity.Profile.Attributes.DisplayName

# Check an entitlement entry and its source metadata
$plan.Request.Context.Views.Identity.Entitlements[0] | Get-Member
$plan.Request.Context.Views.Identity.Entitlements[0].Id
$plan.Request.Context.Views.Identity.Entitlements[0].SourceProvider

Translating discovered structure to Condition paths:

# Profile attribute — path must include Attributes
Condition = @{
  Like = @{
    Path    = 'Request.Context.Providers.Identity.Default.Identity.Profile.Attributes.DisplayName'
    Pattern = '* (Contractor)'
  }
}

# Entitlement IDs — member-access enumeration extracts all Id values from the list
Condition = @{
  NotContains = @{
    Path  = 'Request.Context.Views.Identity.Entitlements.Id'
    Value = 'CN=BreakGlass-Users,OU=Groups,DC=example,DC=com'
  }
}

Ambiguous provider

If multiple providers advertise a capability, specify With.Provider explicitly.

Context value missing

Verify required With parameters.
Ensure template placeholders resolve correctly.
Remember: scoped path uses Providers.<Alias>.<AuthKey>.<SubPath>. Views are only available for IdLE.Entitlement.List and IdLE.Identity.Read.

Profile path not found in Condition

Profile attributes are nested under the Attributes key, not promoted to top-level. Use ...Identity.Profile.Attributes.DisplayName not ...Identity.Profile.DisplayName.
Check the actual structure at plan time: $plan.Request.Context.Providers.<Alias>.<AuthKey>.Identity.Profile | ConvertTo-Json -Depth 4

View differs from source-of-truth path

For IdLE.Identity.Read, profile Views are built by last-writer-wins with a deterministic sort order (provider alias ascending, then auth session key ascending). This means:

Request.Context.Views.Identity.Profile may contain a profile from a different provider/session than a specific scoped path.
This is expected and intentional — Views are convenience aggregations, not direct copies.

If the View contains an unexpected profile, check SourceProvider and SourceAuthSessionName on the profile object to identify its origin:

$plan.Request.Context.Views.Identity.Profile.SourceProvider
$plan.Request.Context.Views.Identity.Profile.SourceAuthSessionName

To get the profile from a specific provider, use the scoped source-of-truth path instead:

$plan.Request.Context.Providers.Entra.Default.Identity.Profile

Type conflict in context path

A resolver cannot overwrite an existing path with incompatible type.
Pre-existing context keys like Providers or Views must be hashtables.

Invalid provider alias or AuthSessionName

Provider alias and AuthSessionName must be valid path segments: ^[A-Za-z0-9][A-Za-z0-9_-]{0,63}$
Dots (.) are not allowed as they are used as path separators.

# Check a specific attribute
$plan.Request.Context.Providers.Identity.Default.Identity.Profile.Attributes.DisplayName

# Check an entitlement entry and its source metadata
$plan.Request.Context.Views.Identity.Entitlements[0] | Get-Member
$plan.Request.Context.Views.Identity.Entitlements[0].Id
$plan.Request.Context.Views.Identity.Entitlements[0].SourceProvider

  NotContains = @{
    Path  = 'Request.Context.Views.Identity.Entitlements.Id'
    Value = 'CN=BreakGlass-Users,OU=Groups,DC=example,DC=com'
