Implementation details (AI-generated)

Fixes from a documentation-vs-behavior audit of the public API:

  • characters().categories(...).excludeCategories(...) now throws — the engine accepts both keys but ignores the exclusion, so the combination silently did nothing.
  • Negative maxSize is always rejected; the -1 unbounded sentinel of the engine ABI no longer leaks through the public API.
  • Default @HegelTest database keys are qualified by declaring class, so same-named test methods in different classes no longer share replay state (changelog notes the one-time invalidation of existing keys).
  • fromRegex documented as unanchored, Python-dialect; added a working fullmatch overload (default remains unanchored).
  • durations() now generates negative durations by default — the engine supports the full signed range, and the docs promised it.
  • Javadoc corrections for datetimes(), forType(), and characters(); README updated to 0.3.0.
  • RELEASE.md (RELEASE_TYPE: minor) for the release automation.

Verification: 220 tests plus the invoker integration test pass, jacoco 100% instruction and branch coverage, spotless and javadoc clean (built on JDK 25, matching the CI matrix).

The engine schema honors only one of the two keys (verified against the
real engine: with both sent, the exclusion is silently ignored), so
TextGenerator emitted categories and dropped exclude_categories whenever
both were configured. Throw IllegalArgumentException at configuration
time instead of silently generating excluded characters.

maxSize(-1) silently meant "unbounded" because -1 is the C ABI's
internal UNBOUNDED sentinel; any other negative value already threw.
The public fluent setters now reject all negative values with an
IllegalArgumentException telling the user to omit the call for no
bound. The sentinel stays internal (factory methods still use it).

The default Settings name (which derives the example-database key) was
the bare method name, so same-named test methods in different classes
shared replay-database entries. The default is now the fully-qualified
declaring class name plus the method name. Existing database entries
stored under bare-method-name keys will no longer be found (a one-time
invalidation); explicit name overrides are unaffected.

…tion

Rebased remnant of "Document fromRegex's unanchored semantics and add a
fullmatch overload": main's regex-fullmatch-default change (PR #9) has
since made fromRegex generate whole-string matches by default with a
fullmatch(boolean) opt-out, superseding the overload and the unanchored
documentation. What remains from the original commit: document that
patterns use the engine's Python re dialect (which differs from
java.util.regex.Pattern in some constructs), and strengthen the
previously-vacuous GeneratorSmokeTest assertion (length() >= 0) to pin
the fullmatch semantics.

durations() silently clamped its range to [0, Long.MAX_VALUE]
nanoseconds even though java.time.Duration is signed (and Hypothesis's
timedeltas covers negatives). The engine's integer schema accepts
negative bounds (verified against the real engine), so the default
range is now the full signed nanosecond range [Long.MIN_VALUE,
Long.MAX_VALUE] (~±292 years) and min()/max() accept negative bounds.
Use durations().min(Duration.ZERO) for the old non-negative behavior.

The javadoc said "single-character strings", but size is measured in
codepoints: a supplementary-plane draw has String.length() == 2, which
breaks naive charAt(0) use. Say so, recommend codePointAt(0), and note
that further size calls replace the one-codepoint contract. Add a
conformance test demonstrating length-2 single-codepoint values.

- datetimes() swapped the two zone methods: timezones(Generator<? extends
  ZoneId>) produces ZonedDateTime and offsets(Generator<ZoneOffset>)
  produces OffsetDateTime, not the other way round.
- forType(Class) advertised List/Set/Optional/Map support that the
  Class-based signature cannot express (those work only as record
  components, where the declared element types are known), and omitted
  the supported java.time scalars. Document the actual supported set,
  the record-component restriction, and the thrown HegelException; pin
  forType(List.class) throwing in DerivationTest.

The Maven and Gradle snippets still said 0.1.0; the latest release per
the CHANGELOG (and the pom) is 0.4.0.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
RELEASE_TYPE is minor per the zerover guidance (breaking changes only):
the durations() range change, the categories()/excludeCategories()
conflict now throwing, the negative-maxSize rejection, and the
example-database key qualification can all break existing usage. The
fromRegex bullet from the pre-rebase entry is gone: main's 0.4.0
release already shipped fullmatch-by-default fromRegex, superseding it;
only the Python-re dialect documentation remains from that commit.
