Document notification architecture limits for stakeholder review
The launch plan describes exactly-once delivery and confirmed readership even though the provider contract supports neither.

Field percentages are editorial estimates of the ticket's engineering focus. They total 100%; they are not measured time, proficiency scores, or ownership evidence.

The board opens an editable draft; nothing is saved until you confirm it. Sign-in and workspace permissions apply, and Demo boards remain ephemeral.
Project context
A fictional collaboration tool sends email and in-app notifications. Duplicate alerts and preference changes reveal that the design has no single definition of delivery.
Setup prerequisites
- Create synthetic recipients, events and fake delivery providers.
- Do not send real email or messages.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- ANOTIFY-101 · Separate notification intent from channel delivery and human receipt
- ANOTIFY-102 · Specify recipient resolution without copying event payloads broadly
- ANOTIFY-103 · Choose when notification preferences are evaluated
- ANOTIFY-104 · Model notification intent and dispatch in one durable transaction
- ANOTIFY-105 · Design per-channel attempt identity and provider reconciliation
- ANOTIFY-106 · Bound notification fan-out without creating one huge transaction
- ANOTIFY-108 · Calculate notification drain time under a channel rate limit
- ANOTIFY-109 · Exercise preference revocation during a notification backlog
Acceptance criteria
- List supported guarantees and unresolved provider dependencies.
- Link each guarantee to a contract or local probe.
- Include retry suspension and backlog recovery decisions.
Implementation constraints
- State that local tests do not prove real provider delivery.
Verification to include
- Trace an accepted guarantee to its executable probe.
- Identify an unsupported receipt claim and replace it with the observed state.
Deliverables
- Notification design review packet
Rollout and recovery
Review the packet before provider rollout; revise claims when adapter evidence changes.
Value of the work
For the engineer: Practice asynchronous contracts, preference timing and delivery uncertainty.
For the team: Review a notification design that controls nuisance, disclosure and recovery.
Evidence boundaries
Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.
Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
