 ## Historical or version-labelled context
 
-Version-labelled `V*.md` files are retained as historical implementation/audit records. Their version number describes the audited milestone. The current release implementation note is [IMPLEMENTATION_0.31.1.md](IMPLEMENTATION_0.31.1.md); [IMPLEMENTATION_0.31.0.md](IMPLEMENTATION_0.31.0.md) is retained as the previous milestone; [V0.29.1_IMPLEMENTATION.md](V0.29.1_IMPLEMENTATION.md) is retained as historical context, and [V0.29.0_IMPLEMENTATION.md](V0.29.0_IMPLEMENTATION.md) is retained as the prior redirect/health/cache/log milestone; [V0.28.2_IMPLEMENTATION.md](V0.28.2_IMPLEMENTATION.md) is retained as the prior certificate-hardening milestone; [V0.28.1_IMPLEMENTATION.md](V0.28.1_IMPLEMENTATION.md) is retained as the prior external-path milestone; [V0.28.0_IMPLEMENTATION.md](V0.28.0_IMPLEMENTATION.md) is retained as the prior GeoIP/listener/cache milestone, and [V0.27.3_IMPLEMENTATION.md](V0.27.3_IMPLEMENTATION.md) is retained as the prior HTTP/3/cache-maintenance milestone, [V0.27.2_IMPLEMENTATION.md](V0.27.2_IMPLEMENTATION.md) is retained as the prior managed-ACME repair, [V0.27.1_IMPLEMENTATION.md](V0.27.1_IMPLEMENTATION.md) as the prior managed-runtime/list-sorting milestone, and older version notes remain historical evidence. The latest retained audit is [V0.25.5_AUDIT.md](V0.25.5_AUDIT.md); older audit files remain available for traceability.
