Summary

• Prepare genkit_llamadart 3.7.0: version 3.6.0 → 3.7.0, and ## Unreleased → ## 3.7.0 - 2026-11-08. The one bullet comes from #1780 (llamadart: ^0.18.0).
• Why 3.7.0: adapter minors track core minors (3.5/0.16, 3.6/0.17), and ^0.18.0 is a new core minor. Public API unchanged.
• Two files only, as release_genkit_on_prep_merge.yml requires. Core llamadart 0.18.0 and the 0.18 Apple companions are on pub.dev, so "core first" holds. Release approved by the maintainer on #1747 ("Go").

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-v3.7.0 and dispatches publish_genkit_pubdev.yml, which publishes genkit_llamadart 3.7.0 and creates its GitHub Release with --latest=false. Core and companion publishers do not run. pub.dev versions cannot be unpublished. If the merge lands on a later day, fix the changelog date first.

Production-readiness scope

• User-facing scope: after merge, genkit_llamadart 3.7.0 (llamadart: ^0.18.0) 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 3.7.0 / llamadart 0.18.0, as #1589 did after 3.6.0. The Genkit ## Unreleased heading returns with the next adapter change, as Move genkit_llamadart to llamadart 0.18 #1780 did after 3.6.0.

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 (Dart 3.13.1), macOS arm64, head 94344434e1397324286fc818b149cfe08c7d60a1.

• 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/: +1576 ~5, including genkit_release_routing_test.dart and genkit_package_staging_test.dart; the only 6 failures are windows_registry_qualification_test.dart, which needs pwsh (not installed on this host).
• dart test -p chrome --exclude-tags local-only: N/A, no core change.
• coverage-lib: N/A, no lib/ change.
• Other targeted/local-only validation:
  • From packages/genkit_llamadart, hosted llamadart 0.18.0: dart format, dart analyze --fatal-infos, python3 .github/check_docs.py, .github unittests: pass. dart test -x real-model: +471.
  • Lower-bound pins ([email protected] [email protected] [email protected] [email protected] [email protected]), in-tree then restored: analyze clean, +471. Local SDK is 3.13.1; CI's lower-bound leg runs exact Dart 3.12.0.
  • stage_genkit_package.py to a fresh directory, dart pub get && dart pub publish --dry-run: 3.7.0, 0 warnings, 584 KB.
  • python3 -B -m unittest discover -s test/ci -p 'test_*.py': OK.
  • verify_release_docs_versions.dart: pass. --release-prep reports only core 0.19 conditions (root ## Unreleased, pending companion native pins), not this Genkit-only release.

Matrix Evidence

Matrix row	Scope covered	Platform / model / backend	Result	Evidence / notes
genkit-release	release isolation, two-file prep scope, tag/version guards, staging	macOS arm64	PASS	routing and staging tests pass; dry-run 0 warnings
genkit-contracts	adapter tests, docs, archive, lower bounds	macOS arm64, hosted llamadart 0.18.0	PASS	+471 published and minimum pins
release-companion-pub-gate	pub.dev version availability	pub.dev API	PASS (pre-merge)	genkit_llamadart 3.7.0 returns 404; latest is 3.6.0; tag genkit_llamadart-v3.7.0 absent

Review Notes

• Independent review status: ACCEPT at exact head 94344434e1397324286fc818b149cfe08c7d60a1 vs base a468360f5c826b01d7d7bea4de442b03df997145 by a fresh Claude Opus auditor session uninvolved in the implementation (operator-owned); 0 blocking findings. Reproduced the staged archive dry-run (file list identical to 3.6.0), lower bounds on Dart 3.12.0 (+471), hosted core (+471) and Genkit tooling tests; confirmed core/companion/docs-cut publishers cannot match genkit_llamadart-v3.7.0. Non-blocking: keep the 2026-11-08 date (merge today); website pins follow publication; the real-model leg runs in the publisher's verify job.
• CI status / head SHA: green at 94344434e1397324286fc818b149cfe08c7d60a1 (CI: Genkit lower bounds and published, Genkit local core, Markdown Tests, Linux & Web pass; 9 success, 21 skipped, 0 failed).
