docs: correct claims that do not match the code (#178)
Each item below was checked against the repository, not just reworded.
Wrong symbols and paths:
- CollectionService lives in collection/, not metadata/ (AGENTS.md,
ARCHITECTURE.md).
- DEVELOPMENT.md named @McpToolParameter; the annotation is @McpToolParam.
- DEVELOPMENT.md had the document-creator roles inverted: formats implement
SolrDocumentCreator and register with the IndexingDocumentCreator.
- .github/workflows/publish-mcp.yml does not exist; the MCP Registry is
published by the publish-mcp-registry job in release-publish.yml.
- The observability test README documented InMemorySpanExporter and
ObservabilityTestConfiguration.java, neither of which exists anywhere
except that README. The tests use SimpleTracer from
micrometer-tracing-test via OpenTelemetryTestConfiguration.
- ARCHITECTURE.md listed a test tree of *DirectTest files that do not exist,
described record DTOs as POJOs, and still listed implemented OAuth2
support under Future Considerations.
- FAQ.md claimed 27 tools; there are 11. It also said every tool returns the
same record while naming two different ones.
Commands that do not work as written:
- TROUBLESHOOTING.md piped STDIO logs with 2>&1, merging diagnostics into
the stdout JSON-RPC stream, and called `gradlew clean --no-build-cache` a
cache purge.
- ATR_TESTING_GUIDE.md ran `ls -lh build/distributions/` after cd-ing into
that directory, and referenced trstringer/manual-approval@v1 - ASF's
Actions allow-list matches by exact SHA, so a mutable tag fails at
startup.
- DEPLOYMENT.md showed an unauthenticated curl of /actuator/info; only
/actuator/health is permitAll.
- DOCKER_PUBLISHING.md passed registry credentials via -Djib.to.auth.*,
putting tokens in the process argument list.
- WORKFLOWS.md advertised a pull_request trigger build-and-publish.yml does
not have - it publishes images, so it must not run on PRs - and described
signing without noting that publication is not gated on it.
- init-solr.sh declared "add-field" twice in one JSON object; the duplicate
key silently won, so the "name" field was never created.
- get-auth0-token.sh sourced .env, executing whatever it contained. Parse
only AUTH0_* assignments instead.
- benchmark-native.sh guarded against premature exit with
`docker inspect >/dev/null`, which also succeeds for an exited container;
check .State.Running. Added -i, without which the stdio profile hits EOF
on stdin and exits immediately.
Stale statements and data:
- docs/security/stdio.md described the trust boundary as the direct parent
process; a descriptor can be inherited or passed on.
- DEVELOPMENT.md called `books` a collection with sample data; init-solr.sh
creates it but the download and post are commented out, so it is empty.
- .run/SolrMcpServerHttp.run.xml shipped a contributor's real Auth0 tenant
URL.
- mydata/devnexus-2026.json carried Atlanta local times with a Z suffix. The
conference runs 4-6 March 2026, before the 8 March DST switch, so all 116
records are UTC-5; converted to real UTC instants, keeping the Z that
Solr's date parsing requires. ConferenceEndToEndIntegrationTest, which
indexes this file, still passes.
Not applied: the correction to docs/specs/graalvm-native-image.md, since
that file was pruned from main by #156.
