Platform/viewport	Phone Chromium/Android and Safari/iPhone where applicable; project matrix320x568,390x844,844x390;1280px at400%zoom and200%text enlargement. OS-native installation is a separate physical-device dependency.
Preconditions/roles	Full waiting roster Alice, Bob, Cara; observers Eve then Finn; countdown not started.
Test data	Observer arrival order Eve older; equal-arrival variant resolves by stable profile ID.
Synchronization	Await the explicit observable conditions and source-defined deadlines below; no fixed sleeps. Harness timeouts do not create a product response-time SLA.
Cleanup	Close case-owned contexts and reset only isolated fixture accounts, rooms or content, including after failure. Preserve shared catalog and real profile data.
Automation readiness	Ready for automation once isolated UI fixture seeding and observations are available; documentation only.
Basis	Specified by cited designs/QBrain; new gap behavior is specified by UI-DEC-01..08. Synthetic fixture identities/data are test configurations.
Execution	Not run here. Existing historical status/evidence remains unchanged; new obligations remain pending/unsatisfied.

Ordered actions and observable results

Step	Action / condition	Observable expected result
1	Have Bob leave before countdown.	Remaining players Alice/Cara keep relative order; Eve is promoted to the last player position.
2	Inspect observers.	Finn remains an observer; player capacity is not exceeded.

Scenario

Feature: AC-30: Pre-countdown observer promotion
  Scenario: TEST-PRECOUNTDOWNOBSERVERPROMOTION-030 design verification
    Given Full waiting roster Alice, Bob, Cara; observers Eve then Finn; countdown not started.
    And the fixture data is Observer arrival order Eve older; equal-arrival variant resolves by stable profile ID.
    When Have Bob leave before countdown.
    Then Remaining players Alice/Cara keep relative order; Eve is promoted to the last player position.
    When Inspect observers.
    Then Finn remains an observer; player capacity is not exceeded.

Boundaries

Criterion references identify intended verification. Non-UI transaction, distribution, release/deployment and native OS guarantees retain separate technical/operational tests; this document is not a claim that a compound criterion passed.
