Both 2026-05-29 (10 chars) and 2026-05-29.png (sliced to 10) resolve to the same date. Consistent.

The PR is well-implemented. The core logic correctly merges binding overrides via inputBindings precedence in getBindings, the overrides only apply to configPath workers (sensible), and tests cover the override, reset, and missing-target cases. The fixtures and types are consistent.

I reviewed PR #14446 thoroughly: the binding override mechanism (bindingOverrides → service bindings → inputBindings taking precedence in getBindings), the new getExport() API, the merge ordering against vars/secrets/config bindings, the reset flow, the fixture changes, and the date-slice change in the web worker. I found no logic bugs, security issues, backward-compatibility violations, or incorrect API behavior. The changes are well-tested (override, reset reload, missing-target error) and internally consistent.

LGTM
