Context

The current TimeShield release is v2.0.0, whose CMake package uses SameMinorVersion compatibility. Consumers may provide dependency targets from a parent project or sibling build instead of installing another package configuration.

Decision

Pin the bundled submodule to the v2.0.0 release and request TimeShield 2.0.0, which expresses the supported 2.0.x line. Before package discovery, reuse an existing time_shield::time_shield target; installed dependency discovery follows the same target-reuse rule for optional packages.

Consequences

Build-tree and installed-package consumers remain composable, while the minimum supported TimeShield API is explicit. Moving to another minor line or changing the compatibility policy requires a new compatibility review and release note.
