FA-24691 / Client state / Open access

Client preference layer resolution: Session only reset · case 01

Session only reset.

Verified by executionVariant 1 · 60 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The session-only-reset client decision evaluates `defaults` instead of `{**defaults,**device,**workspace}`.

VERIFIED REPAIR

Apply the modeled session-only-reset rule: `{**defaults,**device,**workspace}`.

Unsuccessful approach: The partial repair `{**defaults,**device}` still violates the explicit fixture contract.

Case contract

Client preferences overlay defaults, device, workspace and session in that order. Workspace locks exclude session writes. Removing an override reveals the lower layer; serialization preserves its own layer and explicit null/falsy values. Operation session-only-reset has the six explicit input/output oracles below.

Why this case matters

An offline client lifecycle model that isolates a state-management defect without DOM rendering or network services.

Verification & scope

Only the explicitly specified operations and finite deterministic records are modeled; no browser or framework conformance is claimed. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.

Observations recorded using Python 3.12.14 at 2026-09-29T14:40:59.906158+00:00.
