📝 Walkthrough

Walkthrough

The project now supports Python 3.14. The installer handles Alpine ONNX Runtime packages. CI adds Python-version smoke gates and runs the full shard on Python 3.14. Bootstrap tests cover the version range and interpreter selection.

Changes

Python 3.14 support

Layer / File(s) Summary
Python support contract and installer
pyproject.toml, scripts/install-server.sh, changelog.d/tsk-7za6ag-widen-python-314.md
The supported range now includes Python 3.14. The installer accepts Python 3.14, recreates out-of-range virtual environments, and uses Alpine system site packages for py3-onnxruntime.
CI version coverage
.github/workflows/ci.yml
The full shard runs on Python 3.14. Import-smoke jobs cover Python 3.11–3.13, and the aggregate gate includes Python 3.11–3.14.
Bootstrap validation
tests/test_install_bootstrap.py
Tests validate the Python constraint and interpreter selection, including Python 3.14 acceptance and Python 3.13 preference.
README fallback changelog
changelog.d/tsk-qc7ejp-readme-distro-fallbacks.md
The changelog records per-distribution dependency fallbacks under the controller installation command.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to 13768

Installation can fail or unnecessarily provision Python 3.13 when Python 3.14 is already available, so interpreter discovery should be fixed before merge.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Include python3.14 in the candidate list.

If python3.14 is installed but python3 resolves to unsupported Python 3.15, pick_system_python selects no system interpreter. The installer then calls ensure_uv, which only bootstraps uv through curl when uv is absent. That bootstrap can fail, causing the installer to stop; otherwise it provisions Python 3.13 instead of using the installed Python 3.14. Placing python3.14 after python3.11 preserves the tested preference for Python 3.13.

Lead: the measurement this card was blocked on is DONE, and it PASSES. Evidence from a real device, not CI.

I installed this branch on a Nothing Phone (1) running postmarketOS edge (musl aarch64, systemd 262, Python 3.14.7 as the ONLY interpreter — no 3.11/3.12/3.13 on the host, so the widening is the whole install, not a nicety).

pip install -e '.[proxy]' COMPLETED on 3.14/musl. The installer then logged verifying controller importcontroller import ok, and the venv holds 171 packages. No source builds, no wheel fallbacks. That answers the card's "Caveat to measure, do not assume" — wheels were the risk and the full [proxy] set resolves.

onnxruntime specifically: 1.30.0, resolved from /usr/lib/python3.14/site-packages/onnxruntime/__init__.py — i.e. the apk package, not PyPI. That works because the installer ALREADY creates the venv with include-system-site-packages = true (confirmed in the generated pyvenv.cfg). I had expected this to be a gap needing an explicit --system-site-packages step on the Alpine path; it is not. Nothing to add there.

End state: tinyagentos.service active and enabled, /api/setup/status returning {"error":"onboarding_required","needs_onboarding":true}.

This PR is CONFLICTING/DIRTY against dev — rebase it and I will merge. Three unrelated installer bugs surfaced during the same run and are carded separately, none of them yours: tsk-oy3p2l (logind KillUserProcesses kills the install's session cgroup, silently) and tsk-svfy7h (mktemp suffix templates; npm install -g --unsafe-perm rejected by npm>=11). Do not pull them into this branch.

HOLD (lead, pulse #242) — ordering, not a defect in this PR.

update-branch refuses: 422 merge conflict between base and head. Measured conflict surface (git merge-tree origin/dev origin/exec/tsk-7za6ag, branch 10 behind / 2 ahead):

CONFLICT (content): Merge conflict in scripts/install-server.sh
CONFLICT (add/add): Merge conflict in tests/test_install_bootstrap.py

Both conflicts are incidental to this PR's actual change (widen Python to <3.15, trim the CI shard matrix) — they come from install-server.sh moving underneath it.

#3085 touches exactly those same two files and is MERGEABLE with every gate green (only CI still running). Rebasing this PR now would just have to be redone after #3085 lands, so: merge #3085 first, then rebase this one ONCE onto the resulting dev. tsk-svfy7h (claimed by laguna-s-orb) is a third stream on install-server.sh — sequence it after these two.

Labelling lead-blocked so this leaves the throttle population while it waits. Rebase is carded so it re-dispatches rather than dead-ending [[feedback-bounce-needs-a-card]].

The Python 3.14 evidence this PR was blocked on is already posted above and still stands: the full [proxy] set resolves on Python 3.14 / musl aarch64, 171 packages, no source builds.

CORRECTION to my hold comment above: I said "Rebase is carded". It is NOT, and it should not be.

I tried to cut a card for it and spec_cards refused twice, correctly:

  1. a BASE-line card must not say rebase — rewriting BASE's tip drops it from HEAD's ancestry and executor.sh:1029 bounces the PR (tsk-mam4mg);
  2. the merge-forward rewording was refused too — executor.sh:549 bounces any merge commit in BASE..HEAD, and lanes never refresh from dev; the lead refreshes via update-branch at PR time (tsk-q367al burned 2 attempts on this).

So this is a LEAD step, not dispatchable work. Disposition: #3084 stays lead-blocked; once #3085 merges I retry gh api -X PUT repos/jaylfc/taOS/pulls/3084/update-branch. The conflicts are dev-drift in the same two files #3085 rewrites, so they are expected to clear once it lands. If update-branch still 422s afterwards, the residue is a genuine content conflict and I will handle it as lead then.

No card exists for this and none is needed — recording that explicitly so the absence is not later mistaken for a dead-ended bounce.
