[AAASM-2642] ✅ (python-sdk): Verify AAASM-2561 thin pyo3 shim acceptance criteria

[Chisanan232]

Description

Verification subtask for Story AAASM-2561 (Python thin pyo3 shim over aa-sdk-client). Adds verification-reports/verification-report-AAASM-2561.md. Stacked on #79 and #80 (base master).

Verified the acceptance criteria end-to-end:

• Thin shim: RuntimeClient.connect/send_event/close delegate to aa_sdk_client::AssemblyClient; no local UDS transport / codec / policy round-trip remains.
• uv sync + pytest green: 418 passed, 10 skipped (pure-Python install / CI path).
• PyO3 extension builds: maturin develop builds + installs agent_assembly._core; cargo build is warning-free.
• No duplicate runtime-client logic; no security authority in the shim (advisory preflight via aa-sdk-client).
• Native built run: AAASM_RUN_NATIVE_CORE_TESTS=1 pytest → 426 passed, 4 skipped — gated native runtime tests (real UDS mock runtime) and FFI benchmarks pass.

Two findings were fixed during verification (folded into the impl PRs):

1. GIL deadlock under aa-sdk-client's bounded/blocking channel → release the GIL in send_event ([AAASM-2640] ♻️ (aa-ffi-python): Delegate RuntimeClient transport to aa-sdk-client #79, 12fe563).
2. Pre-existing benchmark bug — invalid AuditEntry payload → valid payload so the bench exercises the FFI path ([AAASM-2641] ♻️ (python-sdk): Align _core exports + native tests to the thin shim #80, c0972d1).

• Gated native runtime tests + FFI benchmarks pass against the aa-sdk-client delegation.

🤖 Claude Code — review result

CI: ✅ green (21 pass / 4 skip; SonarCloud finished green). BLOCKED is solely REVIEW_REQUIRED. Stacked on #79/#80.

Scope vs AAASM-2642: ✅ complete — adds verification-reports/verification-report-AAASM-2561.md recording end-to-end AC verification:

• cargo build 0 warnings; maturin develop builds + installs agent_assembly._core → PyO3 extension builds.
• pytest green without native (418 passed) and with native built (426 passed) — gated native runtime tests (real UDS mock runtime) + FFI benchmarks pass against the aa-sdk-client delegation.
• Confirms no duplicate transport remains and the shim holds no security authority.

Story AAASM-2561 acceptance criteria — all met. (AC's "no duplicate in agent-assembly" is Story 9 / AAASM-2562 scope — removing the fat monorepo aa-ffi-* — and is out of this Story.)

Verdict: ✅ Ready to approve & merge last (after #79 and #80).
