Summary

• Prepare genkit_llamadart 3.6.0: version 3.5.0 → 3.6.0, and ## Unreleased → ## 3.6.0 - 2026-10-29. Both bullets come from #1574. The parse bullet now also names Qwen3.5 with thinking off.
• Why 3.6.0: this follows the adapter's own precedent for core-minor moves: 3.4.0 for llamadart 0.15, 3.5.0 for 0.16 (#1364). The ^0.17.0 floor is a new core minor, and the parse fix makes the plugin match the engine and llama-server. The public API is unchanged, so this is not a patch, and nothing calls for a major.
• Two files only, as release_genkit_on_prep_merge.yml requires. The Parse genkit structured output with ChatTemplateEngine.parseRendered #1574 audit doc and test follow-ups are in #1587, which merges first. Core llamadart 0.17.0 is already on pub.dev, so the #922 "core first" order holds.

What merging this PR does

Merging publishes. The branch matches release/genkit_llamadart-vX.Y.Z and changes only the two prep files. So release_genkit_on_prep_merge.yml tags the merge commit genkit_llamadart-v3.6.0 and dispatches publish_genkit_pubdev.yml. That publishes genkit_llamadart 3.6.0 to pub.dev and creates its GitHub Release with --latest=false. Core and companion publishers do not run. pub.dev versions cannot be unpublished, so hold the merge until the release is approved. If the merge lands on a later day, fix the changelog date first.

Production-readiness scope

• User-facing scope: after merge, genkit_llamadart 3.6.0 (llamadart: ^0.17.0) is on pub.dev.
• Supported platforms/paths: unchanged from main.
• Unsupported or intentionally unavailable paths: unchanged from main.
• Out of scope / follow-ups: after publication, update the published-pairing snippets in website/docs/integrations/genkit.md and choosing-an-api.md to 3.6.0 / llamadart 0.17.0, as #1368 did after 3.5.0.

Completeness checklist

• Declared scope is fully implemented, or explicitly reduced above.
• Unsupported platform/option combinations fail loudly with actionable diagnostics or are clearly documented as unavailable. N/A: version and changelog only.
• Public API docs, README/website docs, examples, support matrices, and changelog entries are updated where relevant. Website pairings follow publication, as noted above.
• Regression coverage covers the original issue plus key negative/version-skew paths where relevant. N/A: no code change.
• Public capability changes update the validation coverage registry with a pack or a reasoned, issue-linked exemption; inventory checks pass (or N/A with scope). N/A: no capability change.
• Security/privacy review completed: version and changelog text only.
• Follow-up work that is useful but not required for this PR is tracked in GitHub Issues, or explicitly marked "None" above.

PR type guidance

• Feature PR: N/A, release prep.
• Bugfix PR: N/A, release prep.
• Docs-only PR: N/A. A version changes and the merge publishes.

Test Plan

Pinned Flutter 3.47.1, macOS arm64, head 20bb87fffd69f7e907cb34e5ccab687118e9059c.

• dart run tool/prepare_workspace.dart: no tracked changes.
• dart format --output=none --set-exit-if-changed .: 0 changed.
• dart analyze: no issues.
• dart test -p vm -j 1 --exclude-tags local-only: N/A, no core change; dart test -p vm test/unit/tooling/ +1240 passed (~5 skipped), which includes genkit_release_routing_test.dart and genkit_package_staging_test.dart.
• dart test -p chrome --exclude-tags local-only: N/A, no core change.
• Other targeted/local-only validation:
  • From packages/genkit_llamadart against hosted llamadart 0.17.0: dart format, dart analyze --fatal-infos, python3 .github/check_docs.py: pass. dart test -x real-model: +467 passed.
  • stage_genkit_package.py to a fresh directory, then dart pub publish --dry-run: staged version 3.6.0, 0 warnings.
  • python3 -B -m unittest discover -s test/ci -p 'test_*.py': OK.
  • verify_release_docs_versions.dart in a full clone (151 tags): pass. With --release-prep it reports only core conditions: root CHANGELOG.md and recent-releases.md keep the empty ## Unreleased heading after the core 0.17.0 cut. That applies to core release prep, not to this genkit-only PR. The companion-floor check needs no further tag history.
