Actor journeys

Who is trying to achieve what, and which actions and handoffs lead to the outcome?

This view recovers one bounded journey: a notification owner tries to share a notification with external users. The owner role is inferred from the sharing controller’s notification-owner filter; the filter’s effective enforcement is not established by the supplied analysis. E0017

The evidenced order is email entry, eligibility checks and staging of selected users, then confirmation and issuance of an AddSharedUser request. The model ends at Sharing request issued, not at verified access for the recipient. The controller analysis establishes this orchestration, while separate handler analysis reports applying shared-user operations and saving changes without establishing the complete authorization or duplicate-handling policy. E0017 E0460

Read starts as actor initiation, next as the reported order within this controller flow, and achieves as reaching the bounded outcome. Action ownership distinguishes the inferred human participant from the named controller performing checks. These are published source analyses, not live verification of successful execution.

Elements

Notification owner

Kind: actor Basis: inferred Description: The intended initiating user is inferred from the notification-owner filter attached to the sharing controller. The supplied evidence does not establish which authenticated users that filter actually permits. E0017 Evidence: E0017 Goal: Share a notification with selected external users; this goal is inferred from the sharing flow and its external-user eligibility checks. E0017

Submit sharing email

Kind: action Basis: reported Description: The sharing flow accepts an email address for a prospective shared user and performs email validation before progressing through user-selection checks. E0017 Evidence: E0017 Owner: Notification owner, inferred from the controller’s owner filter; exact runtime initiating role remains unverified. E0017

Check and stage shared users

Kind: action Basis: reported Description: The controller rejects self-sharing, resolves the supplied email to a user, requires an external user, and rejects already-shared users. Selected users are staged in TempData for the confirmation flow. Checks against persisted shared users and the in-memory selection are separate; final duplicate handling is delegated beyond the controller. E0017 Evidence: E0017 Owner: ShareNotificationController. E0017

Confirm sharing

Kind: action Basis: reported Description: The confirmation flow reads the staged shared-user list and its POST sends an AddSharedUser request. The visible POST does not establish model validation or protection against an absent TempData list. E0017 Evidence: E0017 Owner: Notification owner for confirmation, inferred; ShareNotificationController for reading staged users and sending the request. E0017

Sharing request issued

Kind: outcome Basis: reported Description: The bounded controller outcome is issuance of the AddSharedUser request for selected users. This is not proof that recipients can subsequently access the notification. Separate analysis reports that AddSharedUserHandler applies the shared-user operation for each supplied user, saves once, and returns true, but runtime binding and complete access-control behavior remain unestablished. E0017 E0460 Evidence: E0017 E0460

Relationships

Owner initiates sharing

From: Notification owner To: Submit sharing email Relation: starts Basis: inferred Description: Initiation by a notification owner is inferred from the owner-filtered sharing controller and its email-entry flow, rather than from an established actor-to-permission matrix. E0017 Evidence: E0017

Email enters eligibility checks

From: Submit sharing email To: Check and stage shared users Relation: next Basis: reported Description: After accepting and validating the email, the controller proceeds through self-sharing, user resolution, external-user eligibility and already-shared checks before staging the selection. E0017 Evidence: E0017

Staged selection proceeds to confirmation

From: Check and stage shared users To: Confirm sharing Relation: next Basis: reported Description: Selected users are placed in TempData, which the confirmation flow subsequently reads. This relationship depends on the staged list remaining available; the supplied analysis identifies missing or expired TempData as an unresolved failure boundary. E0017 Evidence: E0017

Confirmation issues sharing request

From: Confirm sharing To: Sharing request issued Relation: achieves Basis: reported Description: The confirmation POST sends AddSharedUser using the selected users. The evidenced outcome is the request call, not independently verified persistence, recipient notification or effective access. E0017 Evidence: E0017

Gaps

• Human ownership and authorization: The notification-owner and activity-authorization hooks are visible, but their implementations and effective permissions are not supplied. Follow-up should establish who may initiate and confirm sharing and how notification ownership is checked at execution time. E0017
• Controller-to-handler handoff: The controller sends AddSharedUser, and the corresponding named handler is reported to apply sharing operations and save. Registration and runtime invocation are not established, so no connected handler-execution relationship is asserted here. Follow-up requires dispatch registrations and an integration test spanning confirmation and persistence. E0017 E0460
• Workflow-state failure: Confirmation depends on TempData and may encounter null-dependent behavior when its list is missing or expired. State lifetime, repeated requests and concurrent journeys remain unresolved; these need controller and TempData-provider tests. E0017
• Error meaning: User resolution catches all exceptions and reports an invalid-email error. The visible flow therefore does not distinguish an unknown user from an outage or programming failure. Follow-up should establish the intended error contract and logging behavior. E0017
• Final access and recipient handoff: Persistence is reported in the handler, but complete mutation authorization, duplicate behavior and recipient-visible access are not established. No recipient acknowledgment or notification step is evidenced for this journey, and controller-level audit calls are not visible for confirmation; unseen handlers may provide additional behavior. E0017 E0460

Recovery limitations

• Ownership, mechanism or boundary controls remain explicitly unverified.
• The view includes explicitly marked inference.
