Description

Removes the old Jenkins test pipeline: the Jenkinsfile, the 13 shell scripts in test/ that it called, and the three model lists those scripts read (test/keras-models.txt, test/onnx-models.txt, test/pytorch-models.txt). Also removes Jenkinsfile from the check-manifest ignore list in pyproject.toml.

The Jenkins pipeline converted the example Keras models with these scripts and built them with Vivado HLS 2019.2 or 2020.1. It no longer runs: pull requests show no Jenkins check, only the GitLab pipeline, the GitHub Actions jobs and pre-commit.ci. All tests now run in the GitLab pipeline. test/pytest/generate_ci_yaml.py creates one job for each group of files in test/pytest, and the synthesis tests and their baselines are part of pytest. The Jenkinsfile was still being updated in dependency changes (#1191, #1518), so removing it also saves that work.

No other file refers to the removed files. Kept: test/board/ (added in #1376) and the example-models submodule, which pytest still uses.

Not in this PR: hls4ml config still sets write_tar=True in hls4ml/cli/__init__.py. Commit 91f8f83 added it for the Jenkins tests. Removing it would change what the command writes, so that can be a separate change if wanted.

Type of change

• Bug fix (non-breaking)
• New feature (non-breaking)
• Breaking change (existing configs, APIs or generated code behave differently)
• New frontend / backend
• New layer / operator support
• New configuration option — a new io_type, Strategy, or config attribute
• Research paper implementation
• Documentation
• Build, CI or tooling
• Refactor / cleanup (no functional change)

Affected areas

Backends: none

Frontends:

• Not related to a frontend

Components:

• IR (layers + model graph) / optimizer passes
• C++ templates / HLS sources under hls4ml/templates/
• Profiling, reporting or the CLI
• Packaging, build or CI

Configurations affected and exercised

Backend	io_type	Strategy	Verified
n/a	n/a	n/a	pre-commit, test_agent_docs.py

Tests

No new tests, because this PR only removes files. I ran pre-commit run --hook-stage manual --all-files. All hooks pass except check-manifest. It fails in the same way on main when the git submodules are not checked out, and lists Coyote, ac_types and ac_simutils as missing. test/pytest/test_agent_docs.py passes.

Test configuration (OS, Python, ML framework version, HLS tool version): Linux (EL9), Python 3.11, no HLS tool needed.

AI assistance disclosure

• None — no AI tool was used.
• Assisted — completion, refactoring, docstrings, tests; design and code are mine.
• Substantial — significant AI-generated portions, reviewed and edited by me.
• Agentic — produced largely end-to-end by an AI agent from my prompts.

Tool(s) and model(s): Claude Code (Claude Opus 5.5)

Where it was used: finding the files the old pipeline used, removing them, and this description.

If anything other than None is ticked, confirm all of the following:

• I am the author of this contribution and take full responsibility for
  it. I have read and understood every line and can explain and defend it
  in review.
• I verified the generated code against real hls4ml and HLS semantics —
  no invented APIs, config keys, pragmas or citations.
• All numbers, logs and test results quoted in this PR come from runs I
  actually performed, not from agent output.
• I have the right to submit this work under the project's licence, and to
  my knowledge it does not reproduce third-party code that would conflict
  with it.
• No AI tool is credited as an author in any commit in this branch.

Checklist

Required:

• I have read the contributing guidelines.
• I installed and ran pre-commit on the files I edited.
• I added tests under test/pytest covering this change (a bug fix should
  add a test that fails on main and passes here). (Not applicable: files removed only.)
• I self-reviewed the full diff and it contains no leftover debug code,
  commented-out blocks or unrelated changes.
• The AI assistance disclosure above is complete and accurate.

If applicable:

• Documentation under docs/ updated.
• No new build or synthesis warnings.
• Public API / config schema changes are documented.

Release note

none
