build(deps): drop unused runtime deps; support Python 3.10 and declare >=3.10

[ravibits]

Summary

Two related packaging fixes:

1. Unused runtime dependencies. Five packages in install_requires are never imported by the SDK. Four are removed, one test-only package moves to a dev extra, and python-dotenv is deliberately kept.
2. Python 3.10 support. The SDK couldn't be imported on Python 3.10, and setup.py declared no minimum Python. This PR fixes the import error and declares python_requires=">=3.10".

Dependencies

Package	Where it's actually used	Change
setuptools>=82.0.1,<83.0	Only setup.py (build time). pip supplies it in the build environment	Removed. The <83.0 cap blocked the fix for CVE-2026-59890 / GHSA-h35f-9h28-mq5c (fixed in setuptools 83.0.0) for every project that depends on the SDK
google>=3.0	Nowhere. On PyPI, google is an unofficial Google search-scraper package. google.protobuf comes from protobuf, google.rpc/google.api from googleapis-common-protos, google.adk from google-adk	Removed. It also pulled in beautifulsoup4 and soupsieve
cffi>=1.15.1	Never imported (cryptography still requires it)	Removed
deprecation>=2.1.0	Never imported	Removed
Faker>=33,<41	tests/ only	Moved to the dev extra
python-dotenv>=1.2.2,<2.0	Not imported by the SDK, but docs pages (AgentKit troubleshooting, authorize, bring-your-own-connector) and customer code call load_dotenv() relying on the SDK to install it	Kept in install_requires for backward compatibility

make setup now installs .[flask,fastapi,django,dev], so CI and local test runs still get Faker.

Python 3.10

Before: import scalekit raised TypeError: typing.Optional requires a single type on Python 3.10.

• OrganizationClient.update_organization_session_policy annotates parameters as Optional[TimeUnit].
• TimeUnit is a protobuf EnumTypeWrapper instance, not a class. On 3.10, typing.Optional rejects it when the class is defined, which happens on import. Python 3.11 relaxed that check.
• scalekit/__init__.py imports the client, which imports OrganizationClient, so the whole package failed to import.

Fixes:

• from __future__ import annotations in scalekit/organization.py, so annotations aren't evaluated on import. Nothing in the SDK reads type hints back at runtime. This was the only failing spot, and nothing else in the SDK needs Python 3.11 or newer.
• python_requires=">=3.10" plus 3.10–3.14 classifiers. 3.10 is the real minimum, because grpcio, protobuf and mcp all require it. pip and uv now refuse Python 3.9 with "requires a different Python".
• README.md (said 3.8+, with a tip recommending 3.9) and tests/TEST_README.md (said 3.8) now say 3.10+. The scalekit / scalekit-sdk alias packages already declare requires-python = ">=3.10".

Testing

I built a wheel from this branch. Its metadata has Requires-Python: >=3.10 and the expected dependencies.

Python	Install	All modules import*	Read-only product calls (live env)	Unit tests without credentials
3.9	Refused by pip and uv (requires a different Python)	n/a	n/a	n/a
3.10	✅ (failed on main)	✅	13/13 ✅	185 pass; 34 error with KeyError: 'SCALEKIT_ENV_URL' (needs credentials; same on main)
3.11	✅	✅	13/13 ✅	(CI)
3.12	✅	✅	13/13 ✅
3.13	✅	✅	13/13 ✅	185 pass; same 34 credential-only errors as main
3.14	✅	✅	13/13 ✅

*Every module under scalekit imports except the optional framework integrations, which need their own packages.

• What the product calls cover:

  • SaaSKit: organizations, users, roles, permissions, domains
  • Modular SSO: app and org connections
  • Modular SCIM: directories
  • M2M: organization clients
  • AgentKit: tools, connected accounts, MCP configs
  • Auth: client-credentials token

  Results match the released 2.20.0.

• Session-policy method: update_organization_session_policy's signature loads correctly on 3.10.

• Removed packages: none of them are installed by a clean install.

• make lint passes, and compileall passes on 3.10.

• release.py verify --labels skip-release passes against the current main.

Release

No release (skip-release). Three notes wait in .changes/unreleased for the next release:

• Fixed: import scalekit no longer fails on Python 3.10.
• Changed: the SDK declares Python 3.10 as its minimum (python_requires=">=3.10"). Working installs are unaffected, because the previous release's dependencies already required 3.10.
• Changed: installing the SDK no longer installs setuptools, google, deprecation or Faker, or their dependencies beautifulsoup4, soupsieve and packaging. The SDK no longer pins your environment to setuptools 82.x. Code that imports one of these without declaring it should add it to its own dependencies.

These are a fix and two changes, so they make a patch release.

  • Fixed an import error affecting Python 3.10.
• Documentation
  • Updated the minimum supported Python version to 3.10 in the README and test setup guidance.
  • Package metadata now lists Python 3.10–3.14 as supported versions.
• Setup
  • The setup command now installs the development dependency group alongside the Flask, FastAPI, and Django extras.
  • Some packages are no longer installed as runtime dependencies; add them to your own dependencies if your code requires them.

Walkthrough

The package removes several runtime dependencies and adds Faker to a development extra. The setup target installs that extra. Package metadata and documentation specify Python 3.10 or newer. The organization module enables postponed annotation evaluation.

Changes

Development Dependency Setup

Layer / File(s)	Summary
Dependency declarations and setup setup.py, Makefile, .changes/unreleased/*fewer-runtime-dependencies.yaml	Runtime requirements no longer include google, cffi, setuptools, deprecation, or Faker. setup.py retains python-dotenv as a runtime dependency and adds Faker to the dev extra. The setup target installs dev alongside the existing framework extras. The changelog describes the removed dependencies and the setuptools pin.
Python support declarations setup.py, scalekit/organization.py, README.md, tests/TEST_README.md, .changes/unreleased/*python-3-10*.yaml	Package metadata and documentation specify Python 3.10 or newer. The organization module enables postponed annotation evaluation. Test instructions use editable installation with framework and development extras, or make setup. Changelog entries describe the Python support update and the Python 3.10 import fix.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 6c764

PyPy users whose code imports cffi may need to declare it directly after upgrading. The release notice should explain this narrow dependency change before merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 6c764

The dependency and Python support changes affect SDK installations, but the review found no introduced authorization bypass, new privilege, or changed network authority. Downstream installation environments remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The changed requirements can affect any installation of this SDK, but the reviewed changes do not add a tenant-facing entrypoint or grant the SDK additional authority.

Trust Boundaries and Controls

• observed — Authentication’s protobuf imports are supplied by retained runtime requirements, rather than the removed generic google requirement. No changed authentication control or attacker-input path was identified.

Hardening Proposals

• proposed — Projects seeking a newer setuptools version should verify their build environments independently; removal of the SDK’s runtime version ceiling does not verify already-installed tooling.

While Python ten becomes the one.
