… ap-southeast-2) The API otherwise runs in the region nearest the caller; from the Philippines that was Singapore, about 3.3s a call against about 1.2s in Sydney, because every database read crossed the sea (measured 2026-09-28). Set once on TP_CFG through the kernel's vendor-neutral extra_headers, so the kernel stays clean; a driver test pins it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

What
Every call the TrustPager driver makes now carries
x-region: ap-southeast-2, so the TrustPager API runs next to its database in Sydney.Why
The API runs in the region nearest whoever calls it. From the Philippines that was Singapore, and every database read inside each call crossed the sea: the app's calls averaged about 3.3 seconds. The same call run in Sydney takes about 1.2 seconds (measured 2026-09-28 through api.trustpager.com: 4.2s forced to us-west-2, 1.2s in ap-southeast-2).
How
drivers/trustpager/__init__.py:HOME_REGION_HEADERSset once onTP_CFGthrough the kernel's existing vendor-neutralextra_headers, which the transport merges into every request. The kernel is untouched (tools/check-kernel-clean.pypasses).tests/test_trustpager_driver.py: a test pins the header so it cannot silently disappear.Checks
