"""Phase 90 story E2E (Playwright): upload → (no scan) → edit ignores →
Sync sources.

Source: ``TODO.md`` L3 — "Uploading a source archive should not trigger a
scan — that should be left to the sync button on the RAG page. Right now
the sync starts right away which doesn't give the user time to edit the
ignore list."
Run in isolation (DB must be up: ``podman compose up -d db``):

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

The story gate for the whole **deferred-scan loop** end-to-end against the
real pipeline: an upload indexes **nothing** (phase 90 A1 — unpack +
register only, the button reads "Upload"), the owner edits the new
source's ignore list in the phase-89 per-row editor while the scan is
still owed, and the RAG page's **Sync sources** button performs the scan
and honors the edited ignores (phase 90 A4 — the sync's existing
``kind='local'`` + prune + ``ignore_paths`` path is the proof, no sync
change in this phase).

**Timing (the task's note):** the upload leg needs NO ``slow_llm`` proxy
— the upload makes **zero LLM calls** now (phase 90 removed the model
check + import), so its background run settles in milliseconds and the
2 s status poll settles one tick after the 202. The sync leg is short
(2 files + 1 ignored → a handful of mock-LLM requests), so instead of
racing a timer the suite polls the RAG page's settled sync UI
(``#sync-label`` "Synced HH:MM" + ``#sync-result`` counts) with generous
timeouts — the live "Syncing… <file> (n/m)" label is the
``test_sync_upload_progress.py`` suite's subject, not this one's.

The archive is **built in-test** with Python's ``tarfile``:
``e2e-upload-no-scan.tar.gz`` (source name ``e2e-upload-no-scan``) holds
``alpha.md`` + ``beta.md`` + ``notes/skipme.md`` with markdown sentinels
(``ALPHA-…`` / ``BETA-…`` / ``SKIPME-…``); the v2 archive (test 3, same
basename) modifies ``beta.md``, adds ``gamma.md`` (``GAMMA-…``), and
drops ``alpha.md`` — the in-place-replace subject. ``notes`` is the
phase-89 ignore entry: the pure prefix rule
(``is_ignored("notes/skipme.md", ("notes",))``) excludes the skipme file
from the sync's walk — and from its ``files_total`` (the pre-walk uses
the same ignore tuple), so a 3-file upload imports exactly 2 documents.

Per-module app env (the conftest pattern, module-scoped — mirroring
``test_archive_upload_sources.py``'s local helpers, NOT importing that
module): ``BOR_UPLOAD_DIR`` points at a scratch dir the host-side
assertions inspect (the app runs on the same machine), ``BOR_GIT_SOURCES``
is forced empty (the dev ``.env``'s fallback URL must never render as an
env row or become a second sync source), ``BOR_LLM_BASE_URL`` is the mock
LLM (the sync leg's model check + embeds + overview), and the autouse
``_clean`` truncates the shared Postgres (plus waits for no running
background job — this suite's sync must never leak into the next test).

Contract under test:

* **test 1 — upload does not scan**: the "Upload" button (phase 90 A3)
  → the archive → the 202 "Successfully uploaded — <source>" toast →
  the settled result line "Uploaded <source> — press Sync sources to
  import it." with the terminal no-count status payload
  (``{"message": "uploaded"}``, null/0/0 progress — phase 90 A2); the
  source row is present (Local badge + the phase-89 "Ignore paths"
  control) and its folder exists on the host under ``BOR_UPLOAD_DIR``
  with all three files — but **zero documents are indexed**:
  ``GET /api/docs`` is empty and the RAG catalog (``/sources.html``)
  settles on its empty state;
* **test 2 — ignore list, then Sync scans**: fresh state → upload →
  success line → the row's phase-89 "Ignore paths" editor: type
  ``notes``, Save → the row shows the "1 ignored" count tag (the A5
  round-trip through ``GET``) and the stored row carries
  ``ignore_paths == ["notes"]``; navigate to the RAG page → click
  **Sync sources** (``#sync-btn``) → the sync settles ("Synced HH:MM",
  "2 added", counts on the status endpoint) and the catalog lists
  ``alpha.md`` + ``beta.md`` for the source and **not**
  ``notes/skipme.md`` — the edit made BEFORE the sync is honored;
* **test 3 — re-upload replaces without a scan**: fresh state → upload
  v1, success → upload v2 (same basename: the in-place identity) →
  success again with exactly ONE source row (phase-49 contract — one
  folder, one row) whose on-disk contents are ONLY v2's files — and
  still **zero** documents indexed from it.

Test → story mapping (Playwright Mapping Rule):
1. ``test_upload_does_not_scan``
2. ``test_ignore_list_then_sync_scans``
3. ``test_reupload_replaces_without_scan``
