Eduard van Valkenburg 28389df805 Python: Move SessionStore to core and persist Foundry Responses sessions (#7306)
* Python: Move session persistence into core

Move SessionStore and durable msgspec-backed storage into core, restore sessions in Foundry Responses hosting with per-user isolation, and document the serialization design.

* Python: Address session persistence review feedback

Harden scoped file paths and corruption recovery, preserve session serialization compatibility, clarify dependency placement, and add reproducible benchmark evidence.

* Python: Preserve session snapshot compatibility

Deep-copy in-memory session writes and retain existing Telegram session keys so stored conversations continue resolving.

* Python: Simplify Foundry session isolation

Add experimental FoundrySessionStore backed by Agent Server request context, remove resolver plumbing, and centralize v2 user isolation for sessions, checkpoints, and approvals.

* Python: Reduce Foundry session helper layering

Inline the single-use request user accessor while keeping separate context validation, fingerprint, and directory helpers for their distinct callers.

* Python: Clarify Foundry request context validation

Separate fail-fast request validation from context retrieval so Responses no longer appears to discard a returned context.

* Python: Share Foundry request context helpers

Move protocol validation and user-scope derivation into a dedicated request-context module, leaving the session-store module focused on storage.

Agent Framework hosting helper samples

End-to-end samples for exposing Agent Framework targets through app-owned hosting routes.

The helper-first hosting packages provide protocol conversion and optional execution state. The application still owns the web framework, native SDK clients, authentication, response construction, and deployment shape.

Sample What it shows Packaging
local_responses/ One agent + one @tool + native FastAPI route + Responses helper functions + hosting AgentState + core SessionStore. Local only. Start here to learn the helper seam.
local_responses_workflow/ A workflow target behind a native FastAPI route using Responses helper functions, WorkflowState, explicit CheckpointStorage, and an app-owned checkpoint cursor. Local only.
local_telegram/ One agent + aiogram polling + Telegram conversion helpers + app-owned commands, media policy, and streaming edits. Local only. Requires a Telegram bot token.

Each sample is self-contained with its own pyproject.toml, executable application code, and storage/ directory. HTTP samples also include calling scripts. Samples use [tool.uv.sources] to wire unreleased hosting packages to the upstream repo while those packages are still pre-PyPI. Once those packages publish, drop the [tool.uv.sources] block and let the declared dependencies resolve from PyPI.

Relationship to ../foundry-hosted-agents/

The sibling ../foundry-hosted-agents/ directory contains samples for agents that run inside the Foundry Hosted Agents platform. Those samples use the Foundry-managed protocol surface with no agent-framework-hosting package involved.

Aspect af-hosting/ (this directory) foundry-hosted-agents/
Server stack App-owned framework/native client + hosting protocol helpers Foundry Hosted Agents runtime
Protocol surface The app exposes the route and calls helpers The platform exposes Responses + Invocations
Run target Local Hypercorn (local_responses/, local_responses_workflow/) or native polling (local_telegram/) Hosted Agents or local container targeting the Hosted Agents contract
When to pick this You need custom hosting code or want to learn the helper seam You want the Foundry-managed hosting surface
