Jackson 3.2.1 -> 3.2.3. Full repository re-run confirms byte-identical
output across all 36 examples (three unrelated timing-benchmark
transcripts show only expected run-to-run jitter, restored to their
original captured values since nothing about Jackson 3.2.3 changed
their behavior). jackson-annotations stays pinned at 2.22, confirmed
against jackson-databind 3.2.3's own POM.
37 runnable examples covering the eight feature posts on ankurm.com, verified
against Jackson 3.2.1 on Temurin 21.0.5. Every output committed under docs/ was
produced by run-all.sh.
Also documents 11 places where the published snippets do not compile or do not
behave as printed against a real Jackson 3 build - most notably that
writeValueAsString(List<Base>) silently drops the polymorphic type discriminator,
so the post's serialised output cannot be read back.
