* Python: Add AG-UI approval state store
Key decisions: introduce a bounded process-local server-side Approval State store for AG-UI agent approvals; scope pending approval validation by AG-UI thread id plus the endpoint's configured server-side scope when present; fail closed when approval-like resume decisions arrive without matching server-owned pending Approval State, covering replayed and wrong-scope attempts without requiring Thread Snapshot persistence.
Files changed: packages/ag-ui/agent_framework_ag_ui/_approval_state.py adds the approval-only in-memory store and scoped thread-key helper; _agent.py owns the default store; _endpoint.py forwards the configured scope to approval handling independently of snapshot persistence; _agent_run.py keys pending approvals by scoped thread id and rejects approval resumes with missing state; tests/ag_ui/test_endpoint.py covers successful default resumes, replay failure, and wrong-scope failure without a snapshot store.
Verification: uv run pytest focused approval resume tests -q; uv run poe test -P ag-ui; uv run poe syntax -P ag-ui -C; uv run poe pyright -P ag-ui; git diff --check; git diff --cached --check. uv run poe typing -P ag-ui and uv run poe check -P ag-ui currently stop in mypy before package checking on .venv/lib/python3.13/site-packages/numpy/__init__.pyi using Python 3.12 type-statement syntax under the configured Python 3.11 target.
Notes: local issue/PRD planning artifacts were not staged. Follow-up slices still own already-approved sibling release, queued/auto-approved approval state preservation, replayable tool result persistence, synthetic-skip tightening, and final security/invariant coverage.
* Python: Release AG-UI approved siblings on resume
Key decisions: preserve core already-approved approval request groups inside AG-UI server-side Approval State for the visible approval interrupt; restore those siblings as server-generated approval responses only after the visible canonical resume passes server-owned validation; keep cancelled visible approvals fail-closed without executing or fabricating sibling results.
Files changed: packages/ag-ui/agent_framework_ag_ui/_agent_run.py stores hidden already-approved sibling approval requests with pending approval entries and rehydrates them during resume; packages/ag-ui/tests/ag_ui/test_endpoint.py adds mixed approval-batch endpoint coverage for approved, rejected, and cancelled visible approvals.
Verification: uv run pytest focused mixed approval sibling tests -q; uv run pytest neighboring approval endpoint tests -q; uv run poe syntax -P ag-ui -C; uv run poe pyright -P ag-ui; uv run poe test -P ag-ui; git diff --check; git diff --cached --check. uv run poe typing -P ag-ui and uv run poe check -P ag-ui pass pyright/pyrefly/ty/zuban for this change but still stop in mypy before package checking on .venv/lib/python3.13/site-packages/numpy/__init__.pyi using Python 3.12 type-statement syntax under the configured Python 3.11 target.
Notes: local .ralph, PRD, and CONTEXT.md planning artifacts were not staged. Follow-up slices still own queued/auto-approved approval state preservation, replayable tool result persistence, synthetic-skip tightening, and final security/invariant coverage.
* Python: Preserve AG-UI queued approval state
Key decisions: persist only the core tool-approval state bag inside the AG-UI server-side Approval State Store, keyed by the scoped AG-UI approval thread id; restore that approval-only state into each per-run AgentSession before approval resolution; pop server-collected auto-approved responses into validated server-generated approval messages so they execute exactly like resumed approvals without trusting client state.
Files changed: packages/ag-ui/agent_framework_ag_ui/_approval_state.py stores bounded tool approval state alongside pending approval entries; _agent.py passes the shared store into agent runs; _agent_run.py restores/saves tool approval state and drains collected auto-approved responses through existing pending-approval validation; packages/ag-ui/tests/ag_ui/test_endpoint.py covers queued approval surfacing and auto-approved response execution through SSE behavior.
Verification: uv run pytest focused queued/auto approval endpoint tests -q; uv run pytest neighboring approval endpoint tests -q; uv run poe syntax -P ag-ui -C; uv run poe pyright -P ag-ui; uv run poe test -P ag-ui; git diff --check; git diff --cached --check. uv run poe check -P ag-ui still stops in mypy before package checking on .venv/lib/python3.13/site-packages/numpy/__init__.pyi using Python 3.12 type-statement syntax under the configured Python 3.11 target; syntax, pyright, pyrefly, ty, and zuban portions completed successfully before that failure.
Notes: local .ralph, PRD, and CONTEXT.md planning artifacts were not staged. Follow-up slices still own replayable tool result persistence, synthetic-skip tightening, and final security/invariant coverage.
* Python: Persist AG-UI approved tool results
Key decisions: fold approval-resolved function_result messages into AG-UI Thread Snapshot history under their original tool call ids; strip server-generated canonical function_approvals resume controls from replayable snapshots; keep live TOOL_CALL_RESULT emission unchanged while preserving next-turn provider history validity.
Files changed: packages/ag-ui/agent_framework_ag_ui/_agent_run.py adds snapshot merge helpers for approval-resolved tool results; packages/ag-ui/tests/ag_ui/test_endpoint.py covers mixed approval batch resume, hydration, and next-turn replay through observable endpoint behavior.
Verification: uv run pytest focused replayable approval endpoint test -q; uv run pytest neighboring approval replay tests and test_approval_result_event.py -q; uv run poe syntax -P ag-ui -F; uv run poe syntax -P ag-ui -C; uv run poe pyright -P ag-ui; uv run poe test -P ag-ui; git diff --check; git diff --cached --check. uv run poe check -P ag-ui still stops in mypy before package checking on .venv/lib/python3.13/site-packages/numpy/__init__.pyi using Python 3.12 type-statement syntax under the configured Python 3.11 target; syntax, pyright, pyrefly, ty, and zuban portions completed successfully before that failure.
Notes: local .ralph, PRD, and CONTEXT.md planning artifacts were not staged. Follow-up slices still own synthetic-skip tightening and final security/invariant coverage.
* Python: Limit AG-UI synthetic skipped results
Key decisions: treat server-owned Approval State, current approval resume decisions, and existing replayable tool results as non-abandoned tool calls for AG-UI sanitizer repair; keep the defensive skipped-result fallback for genuinely abandoned tool calls; reject client-injected tool results as insufficient to satisfy pending server-owned Approval State.
Files changed: packages/ag-ui/agent_framework_ag_ui/_message_adapters.py adds protected tool-call context to synthetic skip injection; packages/ag-ui/agent_framework_ag_ui/_agent_run.py derives protected ids from pending approvals and stored approval-only state; packages/ag-ui/tests/ag_ui/test_message_adapters.py and test_endpoint.py cover protected pending calls, resume decisions, abandoned-call repair, and forged tool-result behavior.
Verification: uv run pytest focused sanitizer red/green tests -q; uv run pytest focused pending-approval endpoint tests -q; uv run pytest package sanitizer plus neighboring approval endpoint tests -q; uv run poe syntax -P ag-ui -C; uv run poe pyright -P ag-ui; uv run poe test -P ag-ui; git diff --check; git diff --cached --check. uv run poe typing -P ag-ui passes pyright/pyrefly/ty/zuban but still stops in mypy before package checking on .venv/lib/python3.13/site-packages/numpy/__init__.pyi using Python 3.12 type-statement syntax under the configured Python 3.11 target.
Notes: local .ralph, PRD, and CONTEXT.md planning artifacts were not staged. Follow-up slice still owns final AG-UI approval repair security and exact-once invariant coverage.
* Python: Verify AG-UI approval invariants
Key decisions: cover final AG-UI approval repair invariants at the FastAPI endpoint seam; treat wrong-thread resumes, client-supplied approval message spoofing, and client-injected approval state as non-executing fail-closed paths; assert exact-once replayable tool results for completed approval batches; document that Approval State is process-local and production authentication, authorization, and deployment/storage durability remain application responsibilities.
Files changed: packages/ag-ui/tests/ag_ui/test_endpoint.py adds endpoint-observable security and exact-once coverage; packages/ag-ui/README.md documents Approval State production responsibilities.
Verification: uv run pytest packages/ag-ui/tests/ag_ui/test_endpoint.py -q -k 'approval_resume_wrong_thread or approval_function_name_mismatch_message or approval_argument_mismatch_message or approval_client_fields_do_not_mutate or approval_resume_persists_replayable_tool_results'; uv run poe syntax -P ag-ui -F; uv run poe syntax -P ag-ui -C; uv run poe pyright -P ag-ui; uv run poe test -P ag-ui; uv run poe test-typing -P ag-ui --checker pyright; git diff --check; git diff --cached --check.
Notes: local .ralph, PRD, and CONTEXT.md planning artifacts were not staged. This completes the final AG-UI approval repair security and invariant coverage slice.
