name: E2E (real DeepSeek API)

# Real-API end-to-end suite (`pnpm run test:e2e`). Unlike ci.yml this job
# consumes the DEEPSEEK_API_KEY_EXTERNAL secret (mapped to the env var
# DEEPSEEK_API_KEY the tests read) and hits the external API at
# https://api.deepseek.com (DEEPSEEK_BASE_URL is pinned to it explicitly so a
# stray repo-root .env can't redirect the run).
#
# pull_request IS a trigger, but GitHub withholds repo secrets from BOTH forked
# PRs and Dependabot PRs (the latter are same-repo, fork==false, but still
# keyless). The job-level `if:` below skips the whole job for those untrusted
# PRs. The Dependabot test keys on the PR AUTHOR (pull_request.user.login), not
# github.actor (the run trigger) — a maintainer reopening a Dependabot PR would
# make github.actor human while the PR is still keyless. When the job runs, the
# secret is expected, so the preflight hard-fails if it's missing (a missing
# secret would otherwise make the self-skipping suite report a false green). A
# job skipped by a job-level `if:` reports as a SUCCESSFUL check, so this
# workflow is safe to use as a required status check if desired.
#
# SECURITY — NEVER change this trigger to `pull_request_target`. `pull_request`
# checks out and runs the PR's HEAD code WITHOUT secrets for forks, which is what
# keeps an untrusted fork from exfiltrating the key. `pull_request_target` runs
# in the BASE repo's context WITH secrets while still able to check out untrusted
# fork code — a textbook key-leak vector, especially once this repo is public.
# The fork/secret model and its public-repo implications are recorded in
# .agents/notes/implemented/testing/2026-06-19-real-api-e2e-ci.md.
#
# Note: scheduled triggers are auto-disabled after 60 days of repo inactivity;
# push/pull_request/workflow_dispatch act as backstops.
