* feat: add conversational flows documentation and chat session support
- Introduced a new guide for building multi-turn chat applications using , detailing session management and message handling.
- Added class to facilitate chat interactions, including streaming support and event handling.
- Implemented for class-level defaults and improved input normalization for conversational turns.
- Enhanced event listeners to manage flow events and tracing more effectively, including support for nested crew executions.
- Added tests for conversational flow helpers and kickoff parameters to ensure functionality and reliability.
* linted
* feat: enhance flow event tracing and session management
- Updated TraceCollectionListener to handle nested flows without re-claiming parent session batches.
- Ensured that method execution events are always emitted for tracing, regardless of flow event suppression.
- Improved finalization logic for flow trace batches to respect session deferral flags.
- Added tests to verify that method execution events are emitted correctly when flow events are suppressed and that deferred session finalization is respected in nested flows.
* updated docs
* feat: introduce experimental conversational flow framework
- Added a new module for conversational flow, including classes for managing conversation state, messages, and events.
- Implemented and for structured intent handling and routing.
- Enhanced the class to support turn-oriented conversational applications with built-in routing and message handling.
- Updated to include new classes in the public API.
- Added tests to validate the functionality of the new conversational flow features.
* handled docs
* feat(flow): enhance conversational flow handling and tracing
- Introduced support for deferred multi-turn tracing to maintain continuous event sequences.
- Updated method to delegate to restored checkpoint flows, improving session management.
- Added tests to validate the new tracing behavior and ensure correct event handling in conversational flows.
* fix multimodal test
* better conversational
* adjusted prompt
* drop unused
* fix test
* refactor: rename to and update related documentation
This commit refactors the class to for clarity and consistency across the codebase. The documentation has been updated to reflect this change, ensuring that references to the new class are accurate. Additionally, the alias for legacy imports is maintained for backward compatibility. The changes enhance the overall structure and readability of the conversational flow implementation.
* fix test
* adding experimetnal indicators
* fix test and reloaded cassettes
* cleanup ConversationalFlow class
* addressing double finalization and fixed tests
* improve on emphemeral tracing and adddressing comments
## Summary
- Add a new docs page at `docs/en/guides/flows/inputs-id-deprecation.mdx` that explains the deprecation of `inputs.id` as a `@persist` hydration mechanism and walks users through migrating to `restoreFromStateId` (available in CrewAI **v1.14.5 and later**).
- Wire the page into `docs.json` next to `mastering-flow-state` in all 13 version blocks across all 4 languages (52 nav inserts).
- Add translations for `ar`, `ko`, `pt-BR`
## Summary
- Reverts `b0e2fda` ("fix(flow): add execution_id separate from state.id", COR-48): removes `Flow.execution_id` and points `current_flow_id` / `current_flow_request_id` back at `flow_id` (i.e. `state.id`). The separate per-run tracking id was no longer the right abstraction once `restore_from_state_id` reshapes how `state.id` is assigned;
- Adds an optional `restore_from_state_id` kwarg to `Flow.kickoff` / `Flow.kickoff_async` that hydrates state from a previously-persisted flow's latest snapshot
- Reassigns `state.id` to a fresh value (or `inputs["id"]` if pinned) so the new run's `@persist` writes don't extend the source's history
- Existing `inputs["id"]` resume, `@persist`, and `from_checkpoint` paths are unchanged
## Problem
`@persist` only supports *resume* today: `kickoff(inputs={"id": <uuid>})` hydrates state and continues writing under the same `flow_uuid`. There's no way to **fork** — hydrate from a snapshot but persist under a separate key, leaving the source's history intact. This PR adds that.
| | `state.id` after kickoff | `@persist` writes land under |
|---|---|---|
| `inputs["id"]` (resume) | supplied id | supplied id (extends history) |
| `restore_from_state_id` (fork) | fresh id, or `inputs["id"]` if pinned | new id (source preserved) |
## Behavior
| `inputs.id` | `restore_from_state_id` | Effect |
|---|---|---|
| — | — | Fresh kickoff |
| set | — | Existing resume |
| — | UUID | Fork — new `state.id`, hydrated from source |
| set | UUID | Fork into a pinned `state.id`, hydrated from source |
- Source not found → silent fallback (mirrors existing resume)
- Both `from_checkpoint` and `restore_from_state_id` set → `ValueError`
- `restore_from_state_id=None` → byte-identical to current main
## Design
Fork hydration runs before the existing `inputs` block in `kickoff_async`. On a hit, it calls the same `_restore_state` primitive used by resume, then overwrites `state.id` with a fresh UUID (or `inputs["id"]`). A `fork_succeeded` flag gates the existing `inputs["id"]` path so we don't double-load. `_completed_methods` / `_is_execution_resuming` are intentionally untouched — skip-completed-methods remains the territory of `apply_checkpoint` and `from_pending`.
## Test plan
- [ ] `pytest tests/test_flow_persistence.py` — 5 new tests (four-row matrix, not-found fallback, default no-op, conflict raise) + 6 existing as regression
- [ ] `pytest tests/test_flow.py` — broader flow suite
- [ ] Manual end-to-end against an HITL `@persist` flow
* feat(flow): add optional key param to @persist decorator
Allows users to specify which state attribute to use as the
persistence key instead of always defaulting to state.id.
Usage: @persist(key='conversation_id')
Falls back to state.id when key is not provided (no breaking change).
Raises ValueError if the specified key is missing or falsy on state.
* docs(flow): document @persist key parameter for custom persistence keys
* fix(flow): use explicit None check for persist key to avoid empty-string fallback
