Native clock and private accessibility prerequisites

These are finite harness/environment prerequisites, not packaged browser, physical-device or soak acceptance. All commands ran serially through the recorded outer driver and tools/resource_group.py, with DATA-only scratch and strict census; all three outer receipts confirm stopped descendants.

browser-expiry-native-clock-01

Exact inner command (outer driver adds the required launcher):

browser-announcement-native-headless-01

Exact inner command (outer driver adds the required launcher):

python3 -B tools/ui/announcement_probe.py --mode headless --output /run/media/kmosoti/data/FabricO11y/results/browser-announcement-native-headless-01

Outer exit 1, finished 2026-10-16T02:57:20.689084+00:00.

Exact signer fingerprint/packet and read-only keyring inventory were checked; no host installation or trust modification. Owned cache/state/RPM database scratch was removed, signed package/tool/manuals/raw logs retained. Actual display/AT success is not established.

The headless AT source f90c4be failed before browser/Orca startup: private PID/network/mount/IPC namespaces were observed, but ip link set lo up exited2 with RTNETLINK answers: Operation not permitted. This is an environment/setup failure, not a detected announcement defect. Namespace leader was reaped and outer stop confirmed; all raw evidence and DATA/scratch/announcement retained for the corrective investigation. The exact signal/event/speech/backend assertions remain unchanged and unestablished.
