Thanks for taking on the cross-runtime suite. The structure is right: marker registered, importorskip in place, three runtimes covered. Two things need fixing before this can merge, plus a handful of polish items.

Blockers

1. Retarget to dev, not main.

All v0.5.0 work goes through dev per release tracker #218 ("Sub-PRs target dev, not main directly"). Both of your PRs target main right now. For this PR: rebase the branch onto origin/dev and update the PR base. (I'll make sure this is louder in the contributing docs so future mentees don't trip on the same thing.)

2. The PocketPaw test doesn't actually test PocketPaw.

Issue #228 says "PocketPaw integration runs at the subprocess level." test_pocketpaw.py currently calls Soul.awaken and soul.export through the soul-protocol library directly. That tests soul-protocol's own round-trip, not whether PocketPaw can consume the file. The test would pass even if PocketPaw was completely broken.

To make it a true cross-runtime test, the PocketPaw side should either:

• Subprocess to the paw CLI and verify it can load the soul, or
• Import the pocketpaw Python runtime (separate package) and verify the persona / memory loads through PocketPaw's APIs

The LangChain and CrewAI tests have the right shape: they go through the target runtime's API. PocketPaw should follow the same pattern.

Smaller items

• soul.remember() in test_pocketpaw.py:18 is being deprecated by #236. Switch to soul.note(...).
• Inconsistent skip pattern. test_langchain.py uses pytest.importorskip, test_crewai.py uses try/except ImportError + pytest.skip(allow_module_level=True). Both work, but importorskip is the canonical pytest pattern. Make them consistent.
• Private API access in test_pocketpaw.py:34: recovered_soul._memory._semantic.facts(). Tests that reach into _underscore members break on internal refactors. The cleaner shape is recovered_soul.recall(query=..., type=...) or whatever public API exists.
• readme.md → README.md per convention (matches what the issue spec uses).
• Missing newline at EOF in readme.md.
• Memory round-trip assertion missing for LangChain and CrewAI. Issue acceptance: "LangChain and CrewAI round-trip passes for at least semantic memory." Your current tests only verify persona persistence in the system prompt string. Add at least one semantic-memory assertion per runtime.

What's working

• Marker registration in conftest.py is exactly right
• pytest.importorskip for the LangChain side is idiomatic
• README explains the optional-dependency story clearly so future contributors know why some tests skip locally
• The round-trip kernel test (export, re-awaken, assert) is the right shape

Once the base retarget + the PocketPaw subprocess test land, plus the small polish, this is solid. Good first pass on the cross-runtime story.

@prakashUXtech Thanks for the review, I'll fix the issues asap, also the with pocket paw I got confused because of our earlier conversation about the memory import and export apis not being available, I'll work to improve the test!
