Run a launch tabletop with explicit stop conditions
Operators lack a shared decision point for pausing registration during a surge.

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 course platform expects a registration deadline spike. Capacity assumptions, escalation ownership, and degradation decisions are scattered across old documents.
Setup prerequisites
- Create synthetic registration traces and local dependency doubles with finite connection and request limits.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- BREADINESS-101 · Turn the registration forecast into a workload envelope
- BREADINESS-102 · Inventory dependency quotas and exhaustion behavior
- BREADINESS-103 · Add connection-pool wait time to registration diagnostics
- BREADINESS-104 · Exercise registration idempotency during client reconnects
- BREADINESS-105 · Decouple confirmation delivery from accepted registration
- BREADINESS-106 · Test read-only degradation when enrollment writes are unavailable
- BREADINESS-107 · Review cache warmup without creating a database stampede
- BREADINESS-108 · Decide launch capacity with cost and failure headroom
Acceptance criteria
- Define measurable pause and resume conditions.
- Assign incident and product decision roles.
- Rehearse notification outage and database saturation scenarios.
Implementation constraints
- Record decisions as simulation outcomes.
Verification to include
- Walk through a recoverable surge.
- Keep writes paused when integrity is uncertain.
Deliverables
- Tabletop record.
Rollout and recovery
Review open actions before the hypothetical launch.
Value of the work
For the engineer: Practice readiness reviews, capacity reasoning, and cross-functional operational handoffs.
For the team: Produce a concrete launch-readiness assessment with measurable risks and recovery actions.
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.
