## Current focus — modernization

The 20 runnable examples exist in all six languages. The work now is the staged
modernization (runtime, versions, tests, CI) tracked step by step in
`_plans/modernization-plan.md`. Read it before starting a step, and update its status
table when a step lands. Examples are flipped to **verified** (footer in the chapter) only
The 20 runnable examples exist in all six languages. The staged modernization (runtime,
versions, tests, CI) is tracked step by step in `_plans/modernization-plan.md`. S0 to S14 are
done (2026-10-15) and work is paused; the plan's "Open follow-ups" table lists what is left
(F1-F5: cache ageing, ConanCenter catch-up, a candidate S15 pin refresh and full matrix
re-run). Read the plan before starting a step, and update its status table when a step lands. Examples are flipped to **verified** (footer in the chapter) only
after their `verify.sh` runs green.

- S13 (user, 2026-10-12): examples use each framework's idiomatic persistence: Hibernate ORM with Panache in every Quarkus example that touches a database (01, 04, 25 and any others), Spring Data JPA in the Spring Boot examples, EF Core in the .NET examples. Python (asyncpg), Go (pgx) and C++ (libpq) keep their drivers. Every changed example re-runs `verify.sh` green on Docker Engine; slides (via deck edit files) and site codetabs follow the examples, including the caching, outbox, health and write-back slides; CLAUDE.md's locked stacks name the ORMs.
## Open follow-ups (status 2026-10-15; work paused here)

S0 to S14 are done and main is green (f20e612). Nothing is required; these are the items left, none started.

| Item | Kind | What to do | Trigger |
|---|---|---|---|
| F1 | wait | Superseded Conan cache entries (11 of 33 after S14 and the libcurl bump; usage 4.3 GB) age out after 7 days unused; expect about 3.5 GB. Check with `gh api .../actions/cache/usage`. | after 2026-10-22 |
| F2 | wait | ConanCenter lags upstream: librdkafka 2.16.0, opentelemetry-cpp 1.29.0, drogon 1.9.14, trantor 1.5.29. Re-run every lock with `conan lock create . --lockfile="" --update` (the empty `--lockfile` matters) and verify the changed C++ projects. | when the recipes land |
| F3 | wait | Dependency-capped C++ holds: protobuf 7 (grpc needs <7), abseil 20260526.0 (protobuf 6.33.5 caps it), opentelemetry-proto 1.9.0 (opentelemetry-cpp tool-requires 1.7.0), lua 5.5 (sol2), openssl 4 (drogon), taocpp-pegtl 4 (cppgraphqlgen). | newer grpc / opentelemetry-cpp / sol2 / drogon recipes |
| F4 | option | Pin refresh (candidate S15): the target pins were verified 2026-10-09. Re-check Quarkus, Spring Boot, .NET, the OTel Java agent, Python and Go modules, and the infra images for patch releases; update on a branch. | user decision |
| F5 | option | Full 111-target matrix re-run. The last full run was 2026-10-13 (S14); later changes were verified only on the targets they touched (#86: 01, 05, 11 C++; #87: 26 x6, 12 Python). Pair it with F4. | with F4 |
