π WalkthroughWalkthroughThe PR adds opt-in durable execution for agent chats. It journals tool-loop events, restores completed steps during resume, prevents duplicate tool execution, propagates idempotency keys, and manages run completion across synchronous, asynchronous, custom-LLM, and streaming paths. ChangesDurable execution
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: π High Β· up to Durable resume can currently repeat side effects, lose failed-run state, ignore configured tool limits, or execute tools with the wrong configuration. These behaviors can corrupt replay semantics and exceed safety bounds, so the PR is not ready to merge until the affected paths are corrected. Sequence Diagram(s)sequenceDiagram

Greptile SummaryThe PR adds opt-in durable agent turns backed by RunJournal, including tool-result replay, explicit resume, stable idempotency keys, and sync/async/streaming lifecycle handling. The latest lifecycle fix preserves fatal and retryable tool-error semantics, but currently classifies handled None-returning failures as successful durable runs.
Confidence Score: 4/5The PR is not yet safe to merge because handled chat failures can be permanently recorded as successful durable runs. Removing the result-is-not-None guard causes sync and async durable lifecycles to finalize ordinary failure returns as succeeded and clear their resume pointer, losing the failed run while reporting a false terminal outcome.

- Around line 2648-2663: Ensure interrupted durable runs are finalized as
cancelled before cleanup: in
src/praisonai-agents/praisonaiagents/agent/chat_mixin.py lines 2648-2663, update
the synchronous _chat_impl flow to catch InterruptedError and call
durable_context.finalize("cancelled"); in the same file lines 3306-3329, apply
equivalent handling to the asynchronous _achat_impl flow for InterruptedError
and task cancellation. Preserve the existing cleanup and successful finalization
behavior.
- Around line 4240-4242: Update iter_stream and _start_stream to create a
durable context for the generatorβs full lifetime, finalizing it when streaming
completes or exits. Ensure begin_durable_run is invoked before tool execution so
_durable_sync_tool_executor receives the active context, and route both
streaming branches, including the OpenAI branch, through that wrapper instead of
calling execute_tool directly. Preserve durable run IDs, journaling, and replay
behavior.
In `@src/praisonai-agents/praisonaiagents/agent/durable.py`:
- Around line 72-78: Update completed_steps to count outer model-iteration
events rather than KIND_TOOL_RESULT entries, including the iteration event
emitted by the replay-writing logic around lines 174-180. Ensure ChatMixin
passes max_steps minus completed_steps to every resumed dispatcher path so
resumed runs consume only the remaining iteration budget, including when
parallel tool calls occur.
- Around line 124-162: Update the tool execution flow around execute_tool_fn to
propagate the stable idempotency_key created in the decision/journal path, and
ensure the tool implementation uses it for external side effects and retries.
Preserve the same key across replay so a crash before recording the tool result
cannot cause duplicate writes.
- Around line 214-236: Move synchronous RunJournal I/O off the event loop: in
durable.py, add awaitable allocation and result-recording operations that
preserve sequence ordering, and update wrap_async to await them while retaining
cached-result and tool-execution behavior. In chat_mixin.py, await durable-run
creation, finalization, and journal closure in achat; apply the required changes
at src/praisonai-agents/praisonaiagents/agent/durable.py lines 214-236 and
src/praisonai-agents/praisonaiagents/agent/chat_mixin.py lines 3297-3329.

When a durable sync or async chat handles a guardrail or LLM failure by returning None, this block finalizes the run as succeeded and clears resume_run_id, causing a failed turn to report success and become unavailable for resume.

Fixed in 8173e59. A handled sync or async turn that returns None is now finalized as failed rather than succeeded; the durable run is terminalized and the stale resume pointer is still cleared. I updated both lifecycle regression tests and reran the durable-run suite: 91 passed, 1 skipped.

In `@src/praisonai-agents/praisonaiagents/agent/chat_mixin.py`:
- Around line 4541-4557: Update the direct OpenAI streaming tool-call loop
around _durable_sync_tool_executor to apply _resolve_max_tool_calls() and the
replay-adjusted step budget before invoking each tool, or route execution
through the shared dispatcher. Stop processing additional entries once either
configured limit is reached while preserving existing tool-result handling.
- Around line 4212-4246: The streaming fallback in _start_stream_impl must not
call the public chat() method while _start_stream owns an active durable
context. Replace the fallback at both chat() call sites with failure propagation
or retry logic that reuses the existing durable context, preserving non-durable
behavior and avoiding nested durable lifecycle ownership or repeated side
effects.
- Around line 2268-2270: Update the exception handling in _chat_completion(),
_execute_unified_achat_completion(), and the corresponding handlers near the
additional affected locations so ToolExecutionError is caught and immediately
re-raised before any generic LLM recovery handler. Preserve propagation through
chat() and achat() so failed durable runs remain resumable instead of returning
None or being finalized successfully.
- Around line 2122-2124: Update the exception handling around the durable tool
executor created by _durable_sync_tool_executor so ToolExecutionError and
journal/replay errors are re-raised before the broad non-streaming provider
fallback at the surrounding chat flow. Preserve the existing fallback only for
provider/request errors that are safe to retry, preventing side-effecting
durable tools from executing twice.
- Around line 4541-4557: Update the durable streaming execution around
self._durable_sync_tool_executor and wrap_sync() to thread
tools_override=tool_param through the sync callback, ensuring self.execute_tool
receives the streaming tool configuration instead of resolving only from
self.tools.
- Around line 4581-4582: Update the exception handling around the tool execution
and streaming flow so RunJournal replay-divergence RuntimeError and SQLite
journal-write failures are re-raised before the generic tool-error handler,
rather than converted into tool results. Preserve existing ToolExecutionError
handling while ensuring durable failures reach the outer failure path and
prevent successful finalization or clearing resume_run_id.
- Around line 4344-4346: Update get_response_stream to initialize and increment
iteration_count for streamed tool-call handling, pass
max_iterations=self._resolve_max_steps() to the follow-up execution, and check
the replay-adjusted budget before each model or tool call so processing stops
