chore: relax requires-python floor to >= 3.11

[max-parke-scale]

Summary

• Lower requires-python from >= 3.12,<4 → >= 3.11,<4.
• Add Python :: 3.11 to the classifiers.

Why

scaleapi/scaleapi's packages/egp-api-backend (and 7 other monorepo packages) are pinned to >=3.11,<3.12, blocking adoption of this SDK there. Specifically, SGP-5968 (Insights Generator backend) is swapping from scale-gp-agents to agentex-sdk and Poetry version resolution fails on the current >= 3.12 floor.

Safety

The SDK source parses cleanly at Python 3.11 grammar — no PEP 695 type parameters, no type statement, no other 3.12-only syntax.

Verified with:

import ast, os
for root, _, files in os.walk('agentex'):
    for f in files:
        if not f.endswith('.py'): continue
        with open(os.path.join(root, f)) as fh:
            ast.parse(fh.read(), feature_version=(3, 11))
# 0 syntax errors across all 200+ .py files

The Stainless-generated 3.12 floor appears to be a default, not a real syntactic constraint.

Coordination

Declan pre-approved this relax in conversation with @max-parke-scale.

Test plan

• CI green
• After merge, cut a patch release (v0.11.4) so consumers can update their pin

Greptile Summary

This PR relaxes the requires-python floor from >=3.12,<4 to >=3.11,<4 and adds the Programming Language :: Python :: 3.11 PyPI classifier, unblocking adoption in monorepo packages pinned to >=3.11,<3.12.

• requires-python + classifier: Single-line change in pyproject.toml; the PR's AST-parse verification confirms no 3.12-only syntax is used across the 200+ source files.
• Pyright config: [tool.pyright] pythonVersion remains at 3.12 (flagged in a prior review pass), so type-level 3.11/3.12 differences won't be caught by static analysis until that is updated.
• CI coverage: The test job has no Python version matrix, so runtime compatibility on 3.11 is unvalidated beyond the AST check.

Confidence Score: 5/5

Safe to merge — the change is a one-line metadata relaxation with no modifications to SDK logic.

The diff touches only the requires-python specifier and a PyPI classifier. The author verified zero syntax errors against the 3.11 grammar across all source files, and the Stainless-generated 3.12 floor was a tooling default rather than a real language constraint. No runtime logic, dependencies, or build steps are affected.

No files require special attention; the only changed file is pyproject.toml with a two-line metadata edit.

Important Files Changed

Filename	Overview
pyproject.toml	Lowers requires-python floor from >=3.12 to >=3.11 and adds the corresponding PyPI classifier; syntactically clean, but [tool.pyright] pythonVersion remains at 3.12 and CI has no 3.11 matrix job.

   The requires-python floor was lowered to 3.11, but pythonVersion in the pyright config still targets 3.12. This means pyright validates stdlib types and overloads against 3.12 semantics, so any type-level incompatibilities between 3.11 and 3.12 (e.g., tomllib being stdlib in 3.11 vs not, ExceptionGroup stdlib availability differences in stub resolution, or any sys.version_info-gated overloads) won't be caught by CI when running on a 3.11 host.

   The `requires-python` floor was lowered to 3.11, but `pythonVersion` in the pyright config still targets 3.12. This means pyright validates stdlib types and overloads against 3.12 semantics, so any type-level incompatibilities between 3.11 and 3.12 (e.g., `tomllib` being stdlib in 3.11 vs not, `ExceptionGroup` stdlib availability differences in stub resolution, or any `sys.version_info`-gated overloads) won't be caught by CI when running on a 3.11 host.

### Issue 1 of 1
pyproject.toml:56
**No CI matrix job validates Python 3.11 at runtime**

The CI `test` job uses Rye's default Python (pulled from `pyproject.toml`'s `[tool.rye] python` or the runner default, not a version matrix), so no job actually installs and runs the test suite under Python 3.11. The `ast.parse` check in the PR description only validates syntax — it won't catch usage of 3.12-only stdlib additions (e.g., `itertools.batched`, `pathlib.Path.is_junction`, `os.process_cpu_affinity`) or behaviour differences. Adding a `python-version: ["3.11", "3.12"]` matrix entry to the `test` job in `.github/workflows/ci.yml` would give true confidence for the lowered floor.

Closing as obsoleted — superseded by Stainless config update.

The Stainless project config for agentex now sets targets.python.options.minimum_python_version: "3.11". The next Stainless regen will emit requires-python = ">= 3.11,<4" (plus the Python :: 3.11 classifier) into pyproject.toml natively, no manual patch needed.

This PR's one-line change would only persist as a manual override against the generator, so closing in favor of the config-side fix.

Reopen-able if the regen doesn't produce the expected change.

Reopened — Stainless's python_version_range config option turned out not to fully solve the issue:

• Schema rejected the compound range ">= 3.11,<4" (no commas allowed in this field).
• The unbounded ">= 3.11" was accepted, but Stainless's lockfile-generation pipeline runs uv compile on Python 3.9.18 and refuses to lock a project requiring >= 3.11. Build fails at requirements.lock step.

So the manual pyproject.toml patch in this PR is the unblock path. Stainless's 3-way merge should preserve it across regens per CONTRIBUTING.md.

Separate Stainless-side concern (won't block this PR): their lockfile pipeline should select a Python interpreter that satisfies requires-python, not fall back to the container's 3.9.18. Worth a support ticket — but not for this PR to fix.

Cc @declan-scale if you can hit the merge button when CI's green, this unblocks SGP-5968 → unblocks #143807 → unblocks the v6 IG flag-on.

Follow-up data point — Stainless's python_version_range config field appears non-functional, at least for this project.

After the ">= 3.11" attempt failed at lockfile generation, we tried python_version_range: ">= 3.9". Stainless's build completed successfully this time (no lockfile error since 3.9.18 satisfies >= 3.9), but the regenerated pyproject.toml on next still emitted requires-python = ">= 3.12,<4". The config option seems to be silently ignored at the codegen step — accepted by the schema, passes the build, but doesn't propagate into the generated SDK metadata.

Two possibilities:

• The field needs to be paired with an explicit edition: on the python target (agentex's config has no edition; default may hardcode 3.12).
• The field is intended for something else (maybe a downstream dev/test-environment constraint) and doesn't actually control the SDK's requires-python line.

Either way: the config-side fix is not an off-the-shelf 5-minute change. This PR (manual pyproject.toml patch) is the unblock path; the Stainless field issue needs a support ticket to track separately.

Separately re. pythonVersion = "3.12" under [tool.pyright] at pyproject.toml:~196: that's the pyright type-checker's target version (used for type analysis), not the runtime floor — independent of requires-python and the SDK's actual Python compatibility. Doesn't affect installability or anything user-facing; safe to leave at 3.12 (means the SDK is type-checked against 3.12 features even though it now installs on 3.11). Could be flipped to 3.11 later for consistency, but it's not load-bearing for this PR.

Addressed Greptile's P2 on pyproject.toml:193-196 in commit 66a7369 — pythonVersion in [tool.pyright] flipped from "3.12" → "3.11" to match the new requires-python floor. Pyright will now type-check against 3.11 semantics, so any 3.11-vs-3.12 stdlib/overload drift gets caught at CI rather than slipping through.

Reverting commit 66a7369 — the pyright pythonVersion realignment was wrong; pyright at 3.12 is correct as-is.

When I flipped pythonVersion from "3.12" → "3.11", CI surfaced 116 lint errors: "override" is unknown import symbol across agentex/lib/, plus reportImplicitOverride everywhere it's used.

The root cause: this SDK has two distinct kinds of code with different Python floors:

• Client surface (agentex/, agentex/types/, agentex/resources/) — Stainless-generated, uses from typing_extensions import override → installs and imports cleanly on Python 3.8+. This is what consumers like egp-api-backend import via from agentex import AsyncAgentex.
• Framework code (agentex/lib/) — hand-written, uses from typing import override → requires Python 3.12+. Imported only by agent-side code (e.g., agents running inside the Agentex framework, which run on 3.12+ by convention), never by client consumers.

Crucially agentex/__init__.py does NOT import agentex.lib, so installing + using the client surface on Python 3.11 works fine. The requires-python = ">= 3.11" claim is accurate for the client-side use case (which is the primary install path for this PR).

So pyright at 3.12 is the right setting because it covers the highest-floor portion of the codebase (agentex/lib/). Lowering it would surface false positives in code that legitimately requires 3.12.

Greptile's concern would be valid if the entire SDK was claiming 3.11 support, but the actual semantic claim is: "client surface works on 3.11+; framework code requires 3.12+." A cleaner long-term fix is to migrate the agentex/lib/ from typing import override calls to from typing_extensions import override (13 files, mechanical change) — but that's a separate refactor, out of scope for this PR's requires-python relax.
