graphitron-tree-sitter-natives keeps the maven-archiver 3.6.4 hard-fail: it is deliberately not a child of the parent pom, so the pluginManagement override does not reach it

The root pom’s pluginManagement entry for maven-javadoc-plugin overrides the plugin’s bundled maven-archiver to 3.6.5, because 3.6.4 range-checks project.build.outputTimestamp against a 1980-01-01T00:00:02Z floor and throws on SOURCE_DATE_EPOCH=315532800, the ZIP epoch NixOS exports from stdenv. graphitron-tree-sitter-natives/pom.xml is deliberately not a child of graphitron-rewrite-parent (its header comment gives the reason: inheriting a 10-SNAPSHOT parent with no <snapshotRepository> would publish a natives jar whose parent reference no Central consumer can resolve, and would lock the natives release cadence to the next 10.x rewrite release). It therefore inlines its own maven-javadoc-plugin 3.12.0 declaration with an attach-javadocs jar execution, and the override does not reach it: that goal makes the same MavenArchiver.parseBuildOutputTimestamp call and still hard-fails. failOnError=false on that declaration does not help, because the throw happens before javadoc is invoked.

Latent rather than live: GitHub-hosted runners do not export SOURCE_DATE_EPOCH, and tree-sitter-natives-release.yml does not set it, so CI is unaffected. The exposure is a maintainer cutting a natives release from a shell that exports the variable, where mvn -f graphitron-tree-sitter-natives/pom.xml deploy dies on the javadoc jar. The fix is to copy the same <dependencies> block onto that module’s own plugin declaration, or to set an in-range outputTimestamp there (this module publishes to Central, so unlike the reactor it plausibly wants a reproducible-builds timestamp, which would make the choice a policy decision rather than a workaround). Either way it retires when the plugin version on both declarations moves to a release pinning maven-archiver >= 3.6.5, so whoever does that bump should be the one to notice; the two declarations drifting is itself part of the problem.
