"""Phase 121 story E2E (Playwright): private git sources — a token that
never reaches the UI or the API (LOCKED A2/A6).

Source: ``TODO.md:5`` — "Need a way to add private repos without exposing
the token in the UI (like when adding an https repo
``https://myuser:ghp_xxx@github.com/myuser/my-private-repo.git``)".

Run in isolation (DB must be up: ``podman compose up -d db``):

    uv run pytest tests/e2e/test_git_source_tokens.py -v --no-cov

**No git, no network** — nothing in this suite triggers a sync (the
clone-time credential injection is pinned at the integration level with a
mocked ``clone_or_pull``); this suite drives the real Sources page and
the real admin-only CRUD API and asserts the credential contract on every
surface the owner can see: the rendered row, the page text, every
``title`` attribute, the page HTML, and the raw JSON of
``GET /api/git-sources`` (via the logged-in page context's request
client — the same cookie as the UI).

Per-module app env (the conftest pattern, module-scoped — as in
``test_git_sources_admin.py``): this story's app boots on its own port
(a same-port second uvicorn would die on bind and drive the wrong
server) with ``BOR_GIT_SOURCES`` pinned EMPTY (the phase-61 leak guard —
the operator's local gitignored ``.env`` carries the owner's real source
list, and process env ranks above the ``.env`` file; a leaked env list
would flip the empty-after-removal assertions) and ``BOR_SOURCES_DIR`` /
``BOR_UPLOAD_DIR`` pinned to fresh tmp dirs (the cleanup DELETE must
never aim a rmtree at the operator's real checkouts — the integration
``_settings`` pattern). The mock-calibrated lexical floor is pinned
like the conftest (the 0.30 mock threshold + the code-default 0.35 floor
violate the startup validator).

Contract under test (the phase's completion criteria, UI side):

* add a private repo through the Sources UI (bare URL + the masked
  ``#git-source-token`` field) → 201 → the row renders the BARE URL
  (mono cell + the cell's ``title`` attribute), the token is absent from
  ``document.body.innerText``, every ``title`` attribute, the page HTML,
  and the ``GET /api/git-sources`` raw JSON; the DB row stores the bare
  URL + the token column (the DB is the trusted store); both inputs
  clear and the button re-enables (§7.4 never-stale);
* pasting the old-style embedded-token URL (``user:token@``, no token
  field — the TODO L5 shape) is accepted and normalized server-side
  (LOCKED A6): stored bare + the token column populated, and the token
  (and the username) is nowhere in the UI or the API;
* the per-row editor's ``#ignore-editor-token`` is ``type=password`` and
  opens BLANK (a password is never echoed back — there is no token
  field to prefill from); saving it blank sends a PATCH that OMITS the
  key (the tri-state no-change), gets 200, and the row's stored token is
  KEPT (DB assertion) — the row is intact;
* removing the source (the phase-69 confirmation modal) → 204, the list
  is empty again, and the token is gone from every surface.

Test → mapping:

1. ``test_admin_add_private_repo_token_stays_out_of_ui_and_api``
2. ``test_admin_embedded_token_url_paste_is_normalized_and_hidden``
3. ``test_admin_editor_token_opens_blank_and_save_keeps_token``
4. ``test_admin_remove_private_repo_leaves_empty_list``
