450d4fc9a8 feat(pdf): default output date format to YYYY-MM-DD
User asked to flip the default from YYYYMMDD to YYYY-MM-DD.
ISO is the better default for an accountant CSV workflow:

- Lexicographic sort = chronological sort (no parsing needed).
- Every spreadsheet tool the user might import into recognises
  it as a real date with no ambiguity (US vs EU readers can't
  disagree on the order).
- Hyphens make the year/month/day boundaries scan-able by eye.

Concrete changes:

- New module constant ``DEFAULT_DATE_FORMAT = "%Y-%m-%d"``,
  used as the default for ``format_date()`` and the
  ``output_date_format`` keyword on
  ``scan_pdf_for_transactions``.
- Page's ``_DATE_FORMAT_CHOICES`` reordered so the ISO entry
  is first (index 0 = default Streamlit selection); YYYYMMDD
  drops to second.
- Custom-strftime input default also flips to ``%Y-%m-%d``.

Tests updated to reflect the new default (``test_dates_formatted_iso_by_default``,
``test_short_dates_get_year_from_period``,
``test_compact_format_round_trip``, plus a new
``test_default_is_iso`` for the format_date helper).

34b56b404a fix(pdf): drop statement_period_start/end columns from output
User asked to remove them — the two columns repeated the same
value on every row from a given statement, took up screen space
in the editor, and offered limited value once the date column
already carries the inferred full date.

What's kept:
- ``account_number`` — still stamped onto every row so multi-
  statement CSVs are self-attributing
- ``extract_statement_metadata`` — still runs every scan because
  ``period_end`` is the source of the year inference that binds
  Chase-style short ``01/13`` dates to ``20250113``
- ``_extract_statement_period`` and its tests — period
  detection itself isn't going anywhere, just its appearance in
  the output rows

What's removed:
- ``record["statement_period_start"]`` / ``record["statement_period_end"]``
  assignments in ``scan_pdf_for_transactions``
- The two columns from the page's column-ordering setup
- Tests pinning their presence; replaced with assertions that
  they're explicitly absent

6f2ad57490 fix(pdf): require non-empty description; tighten multi-line merge
User reported "Daily Ledger Balances" entries leaking into
output. Three correlated bugs in the row qualifier:

**1. Empty description is now disqualifying.** A row like
``01/13/2025  $1,000.00`` has a date and an amount but no text
between them — that's a daily-balance entry, a period-summary,
or page furniture. Drop these. New filter sits after
``_description_from_row`` returns: if the description string is
empty (or whitespace-only), continue past the row.

**2. ``prev`` resets per page.** The state that drives multi-
line description merging (the "previous transaction this
continuation might attach to") used to persist across page
boundaries. A no-date no-amount line at the top of page 2
could silently attach to the last transaction on page 1. Fixed
by moving the ``prev`` / ``prev_y_bottom`` declarations into
the outer page loop so each page starts clean.

**3. Multi-line merges now check y-distance.** Before this fix,
ANY no-date no-amount line attached to the previous
transaction's description. A "Daily Ledger Balances" section
header several rows below the last transaction would silently
fold into it. Now the merge only happens when the gap
``current_top - prev_y_bottom <= 25.0`` PDF points — generous
enough for one blank-line gap between wrapped descriptions,
tight enough to reject section headers across paragraph
breaks. The threshold is a module constant
(``_MULTILINE_MERGE_MAX_GAP``) for future tuning if real
statements call for it.

Three new test classes:

- ``TestRequiresDescription.test_empty_description_row_dropped``
  — date+amount-no-text row filtered, real transaction kept.
- ``TestPrevTransactionResetsPerPage.test_no_cross_page_merge``
  — page-1 transaction + page-2 section header = no merge.
- ``TestMultilineMergeYGap`` — close continuation merges
  (10-pt gap), far section header doesn't (100-pt gap).

The original ``TestMultilineDescription.test_continuation_line_merges``
still passes — its setup has a 10-pt gap which is within the
new threshold.

155dd30746 feat(pdf): extract statement header (account + period) + date format
Two related additions for the accountant workflow:

**1. Statement header extraction.** New
``extract_statement_metadata(pages)`` pulls the account number
and statement period out of the first page (falls back to
page 1+2 if either is missing on page 1 — Wells Fargo business
accounts put header info on page 2). Detected fields are
stamped onto EVERY transaction row so a multi-statement CSV is
self-attributing per row::

    {
      "date": "20250113",
      "description": "Coffee Shop",
      "amount_1": -4.50,
      "account_number": "****5678",
      "statement_period_start": "20250101",
      "statement_period_end": "20250131",
      ...
    }

Account-number regex is tolerant of masks (``****1234``),
hyphens (``1234-5678-9012``), and spaces. Period regex looks
for "Statement Period" / "From" / "Period Covered" labels plus
the first 1-2 full-year dates that follow. If only one date is
present near the label, it's used for both start and end (some
statements show only the closing date).

**2. Year inference for short dates.** When the row date is a
short ``01/13`` or ``Jan 13`` without a year, the scanner now
binds the year from the statement period's end date BEFORE
formatting. Doesn't handle the December-in-January-statement
cross-year case (rare; user can edit in the table).

**3. Configurable output date format.** New
``output_date_format`` parameter on ``scan_pdf_for_transactions``
defaults to ``%Y%m%d``. Applied to: the transaction date column
AND the statement period start/end fields. The page surfaces a
dropdown in Scan options with common presets (YYYYMMDD,
YYYY-MM-DD, MM/DD/YYYY, DD/MM/YYYY, ``Mon DD, YYYY``) plus a
Custom option that accepts a raw strftime string.

New helper: ``format_date(iso_str, fmt)`` converts ISO
``YYYY-MM-DD`` to any strftime; passes invalid input through
unchanged so the user can see what was actually there rather
than getting silent empties.

20 new tests cover: format_date, account-number extraction
(masked / hyphenated / spaced / no-label / short), period
extraction (standard / from-to / single-date / no-label),
metadata orchestrator (full header / no pages / page-2
fallback), year inference (US / dash / month-name / no-period /
unparseable), plus an end-to-end class that builds a header'd
PDF with short-date transactions and confirms metadata
attribution + year inference + format round-trip.

3cf935c999 fix(pdf): drop zero-amount rows; multi-date rows clean description
Two corrections from real-statement feedback:

**1. Drop rows where the transaction amount is exactly 0.**
Bank statements include date+amount-shaped noise like
"INTEREST EARNED 0.00", "PAGE TOTAL 0.00", "BALANCE FORWARD
0.00 1,234.56" — all match the date+amount heuristic but
aren't transactions. New filter in
``scan_pdf_for_transactions``: drop rows whose ``amount_1``
parses to exactly 0. Non-zero balances in ``amount_2`` don't
rescue a zero amount_1 — leftmost amount is the canonical
transaction amount. Unparsed-but-non-empty amount strings are
kept (user verifies in the editor).

**2. Multi-date rows: first date wins for the column, every
date excluded from the description.** Chase / BofA / Wells
commonly show both a transaction date and a posting date per
row:

    01/13  01/14  COFFEE SHOP  $4.50

Before this fix, ``_find_dates_in_words`` returned the first
date only and the second date leaked into description as
"01/14 COFFEE SHOP". Now it returns ALL dates with their word
ranges; the scanner uses ``dates[0]`` as the canonical date
and passes every range to the description builder for
exclusion.

The detector's two-pass strategy now also guards against
mixing full-year and short-date matches on the same row.
Previously, a header line like ``Page 1/2 of 3 ... Statement
Date 01/13/2026`` would return both ``1/2`` and ``01/13/2026``,
and ``1/2`` (being leftmost) would have won the date column.
Now: if any full-year date is found on the row, short patterns
are NOT also collected — full year anchors interpretation. A
row with no full-year date (Chase short-date case) still falls
back to short patterns and collects all of them.

New tests:
- ``test_multiple_dates_returned_in_position_order`` —
  ``01/13`` + ``01/14`` both returned, in order
- ``TestMultiDateRow.test_first_date_wins_second_excluded_from_description``
  — end-to-end through ``scan_pdf_for_transactions``
- ``TestZeroAmountRowsAreDropped.test_zero_amount_row_dropped``
  — "INTEREST EARNED 0.00" row dropped while real txn kept
- ``test_negative_amount_kept`` — pin that -40.00 is not
  treated as zero by the filter

bece2b4030 refactor(pdf): rip out templates; heuristic scan + selectable table
User feedback: the template / visual-picker / mode-dispatch
implementation was too complex for the actual workflow.
Statements drift between months, the canvas state didn't survive
multi-page navigation, and accountants don't want to maintain
per-bank configuration just to convert PDFs to CSV.

Start-over design — one public function, one page, no
persistence:

  ``scan_pdf_for_transactions(pdf_bytes) → (rows, warnings)``

A row is "any text line with a date pattern AND at least one
amount pattern." Each detected row is a dict shaped::

    {
      "date": "2026-01-15",
      "description": "Coffee Shop",
      "amount_1": -4.50,
      "amount_2": 1000.00,   # if a second amount was found
      "page": 1,
      "raw": "01/15/2026 Coffee Shop (4.50) 1,000.00",
      "source_file": "chase-jan-2026.pdf",
    }

Multi-line descriptions still merge (no-date no-amount lines
attach to the previous transaction). Multi-PDF batches share a
single combined table with a ``source_file`` column.

**Page UX:**

- Upload PDF(s) → optional Options expander (parens-negative,
  use-OCR) → click Scan → see all detected rows in an
  ``st.data_editor``.
- The editor has an ``Include`` checkbox column (default on),
  plus user-editable date / description / amount cells and a
  read-only ``raw`` column showing the original PDF text for
  verification.
- A ``Columns to include in CSV`` multiselect hides
  ``page`` / ``raw`` from the download by default; user can
  re-add either.
- Download CSV gets only the checked rows.

No template save/load. No visual picker. No mode dispatch. No
column boundaries. No schema migration. No per-bank
configuration files.

**Deletions:**

- ``src/pdf_templates.py`` — template storage layer
- ``src/gui/_drawable_canvas_compat.py`` — Streamlit compat shim
  for the canvas (no canvas now)
- ``tests/test_pdf_templates.py``, ``test_pdf_row_heuristic.py``,
  ``test_drawable_canvas_compat.py`` — covered the removed APIs
- ``build/hooks/hook-streamlit_drawable_canvas.py`` — hook for
  the removed dep
- ``streamlit-drawable-canvas==0.9.3`` from ``requirements.txt``
- The drawable-canvas references in ``build/datatools.spec``

**``src/pdf_extract.py``** shrinks from ~30 helper functions to
~10. Keeps: value parsers, row clusterer, date/amount token
finders, OCR pipeline, dependency guards. The one new public
function ``scan_pdf_for_transactions`` glues them together.

**Tests** (59 passing): the unit layer keeps full coverage of
the building blocks; the smoke layer pins the end-to-end PDF
roundtrip, OCR discovery, dependency-import behavior, and the
multi-line-description merge. The fpdf2-generated fixture PDF
still drives the real-PDF test.

Rollback: ``git revert HEAD`` brings back the template system if
needed — but the simpler model should make that unlikely.

e6ee2e3481 feat(pdf): robust Tesseract discovery + OS-aware install copy
User tried ``brew install tesseract`` in PowerShell after seeing
all three OSes listed inline in the OCR banner — easy mistake
when the install commands are crammed on one line with ``·``
separators. Two changes pre-empt this:

**OS-aware OCR banner.** The expander now detects the user's
platform via ``platform.system()`` and shows only the relevant
install instructions:

- **Windows**: UB-Mannheim installer link, numbered steps,
  explicit "keep the Add to PATH checkbox on" callout, plus a
  fallback paragraph telling the user how to set
  ``DATATOOLS_TESSERACT_PATH`` if they already installed
  without PATH and don't want to reinstall.
- **macOS**: ``brew install tesseract`` with a Homebrew link.
- **Linux**: ``apt install tesseract-ocr`` with a "or your
  distro's equivalent" hedge.

**Robust binary discovery in ``ocr_available()``.** Three-stage:

1. Honor ``DATATOOLS_TESSERACT_PATH`` env var if set — explicit
   override for portable installs or non-default locations.
2. Try ``pytesseract``'s default PATH-based lookup.
3. If PATH lookup fails, probe known Windows install paths
   (``C:\Program Files\Tesseract-OCR\tesseract.exe``,
   the x86 variant, and ``%LOCALAPPDATA%\Programs\Tesseract-OCR\``)
   via the new ``_autodetect_tesseract_path``. On hit, set
   ``pytesseract.pytesseract.tesseract_cmd`` so all subsequent
   ``image_to_data`` calls use the same binary without
   re-discovering.

This means a user who runs the UB-Mannheim installer with
default options but forgets the PATH checkbox will still get
OCR working after a launcher restart, without env-var
gymnastics.

Tests (4 new, 85 total in the suite):

- Auto-detect returns None on non-Windows (no false positives
  on dev laptops).
- Auto-detect finds the binary at a mocked
  ``C:\Program Files\Tesseract-OCR\tesseract.exe``.
- Auto-detect returns None when no candidate exists.
- ``DATATOOLS_TESSERACT_PATH`` env var beats both PATH lookup
  and auto-detect (sets ``tesseract_cmd`` even when the path
  doesn't resolve, so a real binary at a custom location works).

538e23d219 build(pdf): bundle PDF deps in installers + pin versions + smoke tests
Three changes prepare the next tagged release so end users get
the PDF Extractor without ever touching pip.

**Exact-pin the new deps** (``requirements.txt``):

  pdfplumber==0.11.9
  pypdfium2==5.8.0
  pytesseract==0.3.13
  streamlit-drawable-canvas==0.9.3

Tight pins are the right call for these because the GUI's
visual-picker geometry + the parsing-pipeline word positions
depend on stable internal behavior — a quiet upstream tweak to
``extract_words`` or ``page.render`` would re-break the tool on
the next CI build. Bumping requires a deliberate edit + a CI
run, not a transient ``pip install`` resolving to whatever
``setup.py`` pulled.

Existing deps stay on their current ``>=X.Y,<X+1`` ranges; the
user's "tight pin" concern is specifically about the PDF stack.

**Wire the new deps into the PyInstaller bundle** (``build/``):

- ``datatools.spec`` — add ``collect_submodules`` for pdfplumber,
  pdfminer, pypdfium2, streamlit_drawable_canvas, PIL,
  pytesseract; add ``collect_data_files`` for pypdfium2 (PDFium
  native ``.dll``/``.so``/``.dylib``), streamlit_drawable_canvas
  (frontend JS bundle), pdfminer (Adobe CMap tables).
- ``hooks/hook-pypdfium2.py`` — belt-and-braces hook that uses
  ``collect_dynamic_libs`` to force-include the PDFium binary.
  Without this the visual picker silently fails on installed
  builds with a ``FileNotFoundError`` for the shared library.
- ``hooks/hook-streamlit_drawable_canvas.py`` — collects the
  built JS frontend so the canvas iframe loads under the bundled
  Streamlit server instead of rendering blank.

**Tesseract is intentionally NOT bundled** (option A from the
design discussion). Modern bank statements are text-based;
bundling Tesseract would ~triple installer size for a long-tail
case. The in-app banner directs users to install it from
``UB-Mannheim/tesseract`` if they need OCR. Decision is captured
in the ``project-pdf-installer-pending`` memory note.

**Smoke tests** (``tests/test_pdf_extract_smoke.py``, 17 tests)
add the layer above the pure unit tests:

- ``TestDependencyImports`` — each dep imports cleanly
- ``TestRealPdfRoundTrip`` — generates a tiny statement PDF in
  memory with ``fpdf2`` (test-only dep in
  ``requirements-dev.txt``), runs ``extract_pages`` +
  ``apply_template``, asserts 3 rows out with the right signed
  amounts. Catches "the build succeeded but pdfplumber breaks at
  runtime."
- ``TestRenderPageImage`` — exercises ``pypdfium2.render`` so the
  hook-bundled native lib gets a real call. This is the most
  common installer-bug signature (missing .dll) and the test
  catches it before users do.
- ``TestPdfDependencyMissing`` — monkeypatches ``__import__`` to
  simulate a stripped install; confirms the typed exception +
  actionable hint round-trip.
- ``TestPinnedVersionsMatchInstalled`` — parametrized over all
  four pinned dists; uses ``importlib.metadata`` rather than
  ``__version__`` because pypdfium2 doesn't expose it directly.
  Trips if someone bumps the pin without reinstalling.
- ``TestOcrAvailability`` — confirms ``ocr_available()`` returns
  ``(bool, str)`` and ``extract_pages_auto(allow_ocr=False)``
  skips OCR cleanly.

All 81 PDF + audit tests still pass.
