"""Phase 47 E2E (Playwright): quadlet unit files + Jinja templates ride the
A9 import path end to end (A9 revised 2026-08-27, owner permission).

Story: ``.agents/user_stories/quadlet-jinja-import.md``
Run in isolation (DB must be up: ``podman compose up -d db``):

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

Seeding reuses the real import function against ``tests/fixtures/docs/``
with the deterministic mock embeddings — the ``test_import_documents.py``
pattern (truncate the KB, ``import_sources`` in a worker thread). This
suite's re-import changes the KB for the session; it is run in isolation
(A16), so there is no cross-suite interference.

Test → story mapping (Playwright Mapping Rule):
1. ``test_quadlet_and_jinja_indexed`` — ``GET /api/docs`` (admin session)
   lists the four new-format fixtures with non-zero chunk counts and the
   file stem as title — no env configuration needed (default set).
2. ``test_sources_table_shows_them`` (admin) — the Sources table renders
   a row per new file, each with its ``.doc-link`` path link.
3. ``test_container_content_viewable`` — the phase-26 modal shows the
   ``.container`` file's TOML content (``[Container]`` section + sentinel)
   with the stem as title.
4. ``test_jinja_retrievable_not_deflected`` — a question carrying the
   ``.j2`` sentinel FTS-matches the chunk (A8: LOW requires best cosine
   below threshold **and** zero FTS hits) → honest-positive: the answer
   bubble is not ``.is-deflected`` — and (phase 119, LOCKED A1) the
   zero-read turn chips NOTHING (the ``templates/deploy.j2`` retrieval
   doc is suggested context, not a chip; the retired phase-118 A4
   union is gone).

Phase 97 adaptation: the Sources table is the DRILL-DOWN TREE — the
rows live at their folder levels (``docs`` → ``homelab`` → ``quadlet``
/ ``templates``); the drill is the only change, the asserted
rows/links are unchanged.
