name: Claude Code Compatibility Matrix (daily cron)

# Slice 4 of the Claude Code Compatibility Matrix (PRD #26476, issue #26480).
#
# Three triggers per the PRD's "Daily Cron" section:
#   - Daily cron (06:00 UTC) — picks up newly-published Claude Code releases.
#   - `release` of a `v*-stable` tag on this repo — re-runs the matrix the
#     moment a new stable LiteLLM ships.
#   - Manual dispatch — operators can re-run the publisher on demand.
#
# The job runs on a GitHub-hosted ubuntu-latest runner, which gives us a
# fresh VM per run and is "isolated from the main CI environment" in the
# sense that nothing else on this runner survives the run. Since the
# always-latest Claude Code CLI is only installed inside this ephemeral
# VM, a malicious or broken Claude Code release cannot affect the trusted
# build infrastructure used by the PR gate (which lives in CircleCI and
# uses a `latest minus 3 days` Claude Code pin).
#
# Cross-repo authentication (per "Cross-repo authentication" in the PRD):
# A GitHub App installed on `BerriAI/litellm-docs` only, scoped to
# `contents: write`, mints an installation token at job-start. The token
# is only ever used by the publisher, which only ever writes
# `compatibility-matrix.json` (enforced by `select_files_to_commit`).
