//! End-to-end coverage of `ngit send --force-pr --git-server <url>` where the
//! supplied git server is a **plain vanilla** (non-grasp) HTTP git server whose
//! URL is not listed in the repo's kind-30617 announcement.
//!
//! ## What this test covers
//!
//! `select_servers_push_refs_and_generate_pr_or_pr_update_event`
//! (push.rs:422-448) accepts an optional `git_server` argument. When the value
//! ends with `.git` (or starts with `git@`) `user_server_is_direct_url` is set
//! and the URL is prepended to `to_try` verbatim — ahead of all the repo's own
//! announcement-listed servers. That first URL then drives two outcomes:
//!
//! 1. The unsigned PR event is generated with that URL in the `clone` tag
//!    (push.rs:648-655 — generated on the first server in `to_try`, reused for
//!    all subsequent ones).
//! 2. Git data is pushed to the vanilla server via `push_to_remote`
//!    (push.rs:687-695 — the `!is_grasp_server_clone_url` branch of
//!    push.rs:664).
//!
//! The test then verifies that the announcement-listed grasp servers ALSO
//! receive the same PR ref (push.rs:465-472 appends them to `to_try` after the
//! user-supplied server, and the inner loop at push.rs:637 iterates every entry
//! so all servers receive the push).
//!
//! ## Arrangement
//!
//! Steps 1–6 mirror `send_pr.rs` exactly so the two tests can be read side by
//! side; the only departure is the `--git-server` flag in step 7.
//!
//! 1. Harness: one vanilla relay (`"default"`), two grasp servers (`"repo"` and
//!    `"repo_secondary"`), one vanilla git server (`"extra"`).
//! 2. Maintainer publishes the repo with **both** grasps in the announcement.
//!    The vanilla git server is **not** mentioned in the announcement.
//! 3. A fresh contributor clones and checks out the `"feature"` branch.
//! 4. Contributor commits `t3.md` — establishes the fork point.
//! 5. **Maintainer advances `main`** so `merge_base_oid ≠
//!    main_tip_at_send_time`.
//! 6. Contributor commits `t4.md`.
//! 7. Contributor runs `ngit send HEAD~2 --force-pr --title … --description …
//!    --git-server http://127.0.0.1:<port>/test-repo.git`.
//! 8. [`capture_snapshot`] reads all events and git refs; harness drops.
//!
//! ## Coverage (one `#[rstest]` per bullet)
//!
//! 1. Exactly one KIND_PULL_REQUEST event is published.
//! 2. The `a` tag is the canonical 30617 coordinate for the maintainer's repo.
//! 3. The `c` tag equals the contributor's feature-branch tip OID.
//! 4. The `merge-base` tag equals the fork point.
//! 5. The `branch-name` tag equals `"feature"`.
//! 6. The PR event's `clone` tag has exactly one URL equal to the vanilla
//!    server's URL (not any grasp URL).
//! 7. All three servers — both grasps and the vanilla git server — have a
//!    `refs/nostr/<event_id>` ref resolving to the contributor's tip OID.
//! 8. The vanilla server's URL does NOT appear in the repo announcement's
//!    `clone` tag (the server was bypassed at push time, not registered).
//! 9. No KIND_PULL_REQUEST_UPDATE event was emitted on any surface.
