The central `browser.allowAgentBackgroundWorkers` gate defaults false. The
|
|
|
|
|
permission-only `network:background` scope is also explicit in both the agent
|
|
|
|
|
baseline and individual grant; it is not a callable agent RPC. User profiles can
|
|
|
|
|
inherit or deny this feature (`features.agentBackgroundWorkers`); they cannot
|
|
|
|
|
allow it beyond baseline or grant. Applicable denials accumulate.

Development support is restricted to immutable, nonpersistent native browser
|
|
|
|
|
partitions owned by the enrolled device, individual principal and credential
|
|
|
|
|
generation. Human/default shared partitions, legacy callers and unattributed
|
|
|
|
|
worker traffic remain blocked. Enabling this feature is not general human browser
|
|
|
|
|
worker compatibility, persistence or cross-device worker roaming.

|
Before network release the owner registry must prove the worker's partition,
|
|
|
|
|
registration/source and native context; current policy, grant generation/expiry,
|
|
|
|
|
destination and DLP remain mandatory. The foreground tab or a renderer-provided
|
|
|
|
|
identity cannot establish ownership. Revocation must deny existing worker traffic,
|
|
|
|
|
not merely prevent new registrations. No cloud inspection or extra worker scope
|
|
|
|
|
bypasses local mandatory inspection.

## Verification status

The current real Electron admin workflow exercised typed login-rule editing,
|
|
|
|
|
independent signed publication and auditor read-only access. All 193 completed
|
|
|
|
|
API requests had exported traces; one canceled read had no failed mutation.
|
|
|
|
|
The collector reported zero rejected writes. Trace examples:
|
|
|
|
|
`a0f881d3c99650c53bacf547a191b216` and
|
|
|
|
|
`4416533c41ffe3e2adb81af46a30e0d4`.

Focused policy tests verify the disabled default, preservation through signed
|
|
|
|
|
publication, strict boolean validation and rejection of `network:background`
|
|
|
|
|
as an executable RPC. Eleven registry tests cover immutable ownership,
|
|
|
|
|
installation-before-network-use, revocation and retryable failed cleanup.

The central gate/scope controls start unchecked, and profile schema/enforcement
|
|
|
|
|
prove inherit/deny-only behavior. The actual Windows/Electron admin fixture also verifies the worker gate/scope
|
|
|
|
|
start off, auditor controls are disabled, and typed login-rule creation goes
|
|
|
|
|
through exact signed independent review and policy-history restoration. Its 193
|
|
|
|
|
completed API requests export parent-correlated spans; one canceled GET during
|
|
|
|
|
identity reload is recorded separately, with no failed mutation. See
|

Runtime owner-registry migration, actual native worker attribution/revocation
|
|
|
|
|
tests, runtime traces and final Windows/package proof are pending. Do not claim worker support solely from a stored policy flag.
