kevinveenbirkenbachandClaude Opus 4.7 2a023ca6a1 chore(lint): autoformat strict-failure semantics + claude.sh rename
* scripts/lint/autoformat.sh:
  - rename run_sort_claude_settings worker to run_claude (matches the
    renamed scripts/lint/claude.sh).
  - drop the EXIT trap that wiped status_dir; cleanup happens explicitly
    after `wait` returns, so a parallel worker that interrupts the
    parent never races a vanished status dir.
  - each worker now captures its tool's exit code and writes one of
    OK / SKIP / FAIL. Tolerated `expected violations remain`-style exits
    (markdownlint-cli2 rc≤1, ansible-lint rc≤2) still count as OK; only
    real failures count as FAIL.
  - all workers run to completion regardless of individual tool failures
    (so the user always sees the full picture); after the summary, the
    script exits 1 if any worker reported FAIL.
* scripts/lint/sort_claude_settings.sh -> scripts/lint/claude.sh
  (history preserved via git mv); update test_claude_settings_sorted.py
  fix-hint accordingly.

Plus working-tree drift across roles/, group_vars/, inventories/,
requirements/, and .pre-commit-config.yaml accumulated from the
make-test setup phase regenerating generated artefacts during recent
test runs.

System Utility: Git Pull (Shallow & Pinned)

Description

This Ansible role provides a robust, reusable Git pull utility for system automation. It performs shallow clones or updates of Git repositories and optionally pins the working tree to a specific tag (e.g. stable) in a detached HEAD state.

The role is designed to solve common automation pitfalls such as:

  • conflicting local tags (would clobber existing tag)
  • detached HEAD updates
  • annotated vs. lightweight tags
  • reliable change detection for Ansible

Internally, the role delegates complex Git logic to a small, well-tested Python helper script, keeping the Ansible YAML concise and readable.


Overview

This role:

  • Ensures a repository exists at a given destination
  • Clones the repository shallowly if it does not exist
  • Updates an existing repository in a detached-safe manner
  • Optionally removes conflicting local tags before fetching
  • Optionally pins the checkout to a specific tag (e.g. stable)
  • Marks the Ansible task as changed if:
    • the repository was cloned
    • tags were removed
    • the pinned tag appeared for the first time
    • the pinned tag moved on the remote (optional)

Purpose

The purpose of this role is to provide a generic, reusable Git pull primitive for other roles in the Infinito.Nexus ecosystem.

Typical use cases include:

  • installing tools pinned to a stable tag
  • reproducible system deployments
  • CI/CD-friendly shallow clones
  • avoiding fragile inline Git shell logic in roles

Features

  • Shallow Clone & Update (--depth)
  • Detached-safe Branch Updates
  • Optional Tag Pinning (e.g. stable)
  • Annotated Tag Support (tag^{})
  • Local Tag Conflict Healing
  • Deterministic changed_when Semantics
  • Verbose Debug Logging (stderr-only)

Design Notes

  • All human-readable logs go to stderr
  • Machine-readable state (CHANGED=…) is written to stdout
  • This guarantees reliable changed_when behavior in Ansible
  • The Python helper is intentionally self-contained and unit-testable
