Four distinct tasks make up the work: (1) remove nine dead private methods from `BankStatementProcessor` (the IBAN grouper, all filter helpers, and both CSV writing helpers); (2) inline `PDFProcessingOrchestrator._process_single_pdf` — a 3-line passthrough that adds no value; (3) redirect the two named production importers (`extraction_orchestrator.py`, `pdf_extractor.py`) off the backward-compat shim to the real facades; and (4) add a `DeprecationWarning` to the shim and a pytest guard that will catch any future accidental shim imports in production code. + +The codebase is already well-prepared for every change. `TransactionFilterService` already has `filter_empty_rows`, `filter_header_rows`, and `filter_invalid_dates` — none of the private methods on `BankStatementProcessor` need to be moved anywhere. `OutputOrchestrator.write_output_files()` already owns CSV-with-totals logic. `extraction_facade.py` and `validation_facade.py` already export exactly the symbols that the shim currently re-exports, and `pdf_extractor.py` already uses inline local imports, so the replacement style is already established. + +The shim guard pytest test is the only net-new code (aside from the `warnings.warn` call and dead-code deletions). The existing test for `extraction_orchestrator.py` patches `bankstatements_core.services.extraction_orchestrator.extract_tables_from_pdf` — that patch target string must be updated when the import moves from the shim to `extraction_facade`. Three test files (`test_pdf_table_extractor.py`, `test_env_parsing_logging.py`, `tests/templates/test_template_integration.py`) currently import from the shim and will trigger the new `DeprecationWarning`; those test-level shim imports are legitimate and must be exempted from the guard (or the guard must search only `src/`, not `tests/`). + +**Primary recommendation:** Work in five atomic commits — dead-code removal, `_process_single_pdf` inline, `extraction_orchestrator.py` import switch, `pdf_extractor.py` import switch, then shim deprecation + guard — so each commit is independently green and revertable. + +--- + +## Standard Stack + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| Python `warnings` stdlib | 3.11+ | Runtime deprecation notices | Built-in; no dependency needed | +| `pytest` | >=7.0.0 (project) | Test suite | Already the project's test framework | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| `pytest-cov` | >=4.0.0 (project) | Coverage enforcement (91% threshold) | Runs with every `pytest` invocation via pyproject addopts | + +No new libraries required.

Since all three callers are being deleted, `_filter_rows` itself is deleted too. No move to `TransactionFilterService` needed. + +### Pattern 2: Method Inlining +**What:** Replace a single-line method call with its body, then delete the method. +**When to use:** When a method contains nothing but a delegation to another object with no pre/post logic. + +`PDFProcessingOrchestrator._process_single_pdf` (lines 185-200): +```python +# BEFORE — in process_all_pdfs: +result = self._process_single_pdf(pdf) + +# _process_single_pdf body: +rows, page_count, iban = self.extraction_orchestrator.extract_from_pdf(pdf) +return rows, page_count, iban + +# AFTER — inlined at the call site: +rows, page_count, iban = self.extraction_orchestrator.extract_from_pdf(pdf) +``` +The `result = self._process_single_pdf(pdf)` line plus the subsequent `rows, page_count, iban = result` unpack collapse to a single direct call. + +### Pattern 3: Import Target Redirect (extraction_orchestrator.py) +**What:** Replace the shim import with the direct facade import. + +```python +# BEFORE (line 16): +from bankstatements_core.pdf_table_extractor import extract_tables_from_pdf + +# AFTER: +from bankstatements_core.extraction.extraction_facade import extract_tables_from_pdf +``` + +The function signature and behaviour are identical — `extraction_facade.extract_tables_from_pdf` is exactly what the shim re-exports. The existing test patches `bankstatements_core.services.extraction_orchestrator.extract_tables_from_pdf` — this patch target remains valid after the redirect because it patches the name in the module's namespace, which is what changes. + +### Pattern 4: Inline Import Redirect (pdf_extractor.py) +**What:** Replace 5 separate inline (inside-method) shim imports with direct facade imports. + +Current shim imports in `pdf_extractor.py` and their direct replacements: + +| Shim import | Direct import | +|-------------|---------------| +| `from bankstatements_core.pdf_table_extractor import validate_page_structure` | `from bankstatements_core.extraction.validation_facade import validate_page_structure` | +| `from bankstatements_core.pdf_table_extractor import merge_continuation_lines` | `from bankstatements_core.extraction.validation_facade import merge_continuation_lines` | +| `from bankstatements_core.pdf_table_extractor import detect_table_headers` (×2 occurrences) | `from bankstatements_core.extraction.validation_facade import detect_table_headers` | +| `from bankstatements_core.pdf_table_extractor import detect_table_end_boundary_smart` | `from bankstatements_core.extraction.extraction_facade import detect_table_end_boundary_smart` | + +Decision: keep them as inline imports (matching existing style) OR hoist all five to top-level. Either is acceptable — the existing code already uses inline imports, so matching that style is lower risk. This is within Claude's Discretion. + +### Pattern 5: Module-Level DeprecationWarning +**What:** Emit a warning when the shim module is imported. + +```python +# Add near the top of pdf_table_extractor.py, after the existing imports: +import warnings +warnings.warn( + "bankstatements_core.pdf_table_extractor is a backward-compatibility shim " + "and will be removed in a future version. " + "Import directly from bankstatements_core.extraction.extraction_facade, " + "bankstatements_core.extraction.validation_facade, or " + "bankstatements_core.extraction.row_classification_facade instead.", + DeprecationWarning, + stacklevel=2, +) +``` + +`stacklevel=2` is correct for a module-level `warnings.warn` call — it causes the warning to point to the caller's import statement rather than to this file. + +**Impact on existing tests:** Three test files import from the shim: +- `tests/test_pdf_table_extractor.py` +- `tests/test_env_parsing_logging.py` +- `tests/templates/test_template_integration.py` + +These will now emit `DeprecationWarning` during test collection. The project's `pyproject.toml` `filterwarnings` section currently only silences one `RuntimeWarning`. Options: +1. Add `"ignore::DeprecationWarning:bankstatements_core.pdf_table_extractor"` to `filterwarnings` in `pyproject.toml` — keeps test output clean. +2. Add `pytestmark = pytest.mark.filterwarnings("ignore::DeprecationWarning")` in each affected test file. +3. Do nothing — the warning will appear in test output but tests will still pass. + +Recommended: add to `pyproject.toml` filterwarnings so the warning is suppressed for the test files that legitimately use the shim. The shim guard (see below) will catch production code separately. + +### Pattern 6: CI Shim Import Guard (pytest test) +**What:** A pytest test that scans `packages/*/src/` for import statements referencing `bankstatements_core.pdf_table_extractor` and fails if any are found. This enforces the contract that the shim is external-use-only. + +```python +# Placement recommendation: tests/test_architecture.py (new file) or +# append to an existing architecture/style test such as tests/test_logging_style.py + +import re +from pathlib import Path + + +def test_no_production_shim_imports(): + """Production source must not import from pdf_table_extractor shim.""" + src_root = Path(__file__).parent.parent / "src" + pattern = re.compile( + r"from\s+bankstatements_core\.pdf_table_extractor\s+import" + r"|import\s+bankstatements_core\.pdf_table_extractor" + ) + violations = [] + for py_file in src_root.rglob("*.py"): + # Skip the shim itself + if py_file.name == "pdf_table_extractor.py": + continue + text = py_file.read_text(encoding="utf-8") + for i, line in enumerate(text.splitlines(), 1): + if pattern.search(line): + violations.append(f"{py_file.relative_to(src_root)}:{i}: {line.strip()}") + assert not violations, ( + "Production source imports from deprecated shim:\n" + "\n".join(violations) + ) +``` + +**Placement decision (Claude's Discretion):** Either a new `tests/test_architecture.py` file (clear intent, easy to find) or appended to the existing `tests/test_logging_style.py` (which already tests code style properties). A new `test_architecture.py` is preferred for discoverability. + +### Anti-Patterns to Avoid +- **Grepping tests/ as well as src/:** The guard must exclude `tests/` — test files that exercise shim backward compatibility are legitimate. +- **Moving `_filter_rows` to `TransactionFilterService`:** It is used nowhere except the three callers being deleted. Deleting it is simpler and cleaner. +- **Hoisting inline imports in pdf_extractor.py to top-level in the same commit as the redirect:** These are two independent concerns. If hoisting is desired, do it in a separate follow-up commit so diffs are clear. +- **Deleting shim:** Out of scope — external callers must not be broken. + +--- + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Import-scanning guard | Custom AST parser | `Path.rglob` + `re.compile` | Simple regex on text is sufficient for import-pattern detection; no AST overhead needed | +| DeprecationWarning emission | Custom warning class | `warnings.warn(..., DeprecationWarning, stacklevel=2)` | Standard Python pattern; `stacklevel=2` correctly attributes the warning to the caller | + +**Key insight:** Every capability needed for this phase already exists in the stdlib or the project's existing services. The phase is entirely deletions + redirects + a small new test. + +--- + +## Common Pitfalls + +### Pitfall 1: Stale Patch Targets in Tests +**What goes wrong:** After redirecting `extraction_orchestrator.py` to import from `extraction_facade`, the mock patch `@patch("bankstatements_core.services.extraction_orchestrator.extract_tables_from_pdf")` may appear to still work — but actually it already patches the name in the module namespace, which is correct. The patch target string does NOT need to change. +**Why it happens:** Confusion between "where the function is defined" vs "where the name lives at patch time." +**How to avoid:** Run `tests/services/test_extraction_orchestrator.py` immediately after the import switch — all 9 tests should pass without modification. +**Warning signs:** If `mock_extract.assert_called_once()` fails, the patch target is wrong. + +### Pitfall 2: DeprecationWarning Breaks Test Collection +**What goes wrong:** Adding `warnings.warn(..., DeprecationWarning)` at module import time will cause pytest to emit warnings during collection for any test that imports from the shim. With `--strict-config` enabled (which is set), this does NOT cause failures unless `filterwarnings = "error"` is also set (it is not). +**Why it happens:** Module-level code runs at import time; pytest imports all test modules during collection. +**How to avoid:** Add `"ignore::DeprecationWarning:bankstatements_core"` to the `filterwarnings` list in `pyproject.toml`. Check the three affected test files after adding the warning. +**Warning signs:** Test output suddenly shows many `DeprecationWarning` lines during collection. + +### Pitfall 3: Guard Test Fires on the Shim Itself +**What goes wrong:** The regex that scans `src/` for shim imports will match `pdf_table_extractor.py`'s own `__all__` docstring or comments. +**Why it happens:** The shim file itself contains the string `bankstatements_core.pdf_table_extractor` in its module docstring. +**How to avoid:** The guard must `continue` / skip the file `pdf_table_extractor.py` explicitly. Shown in the code example above. + +### Pitfall 4: Coverage Drop Below 91% After Deletion +**What goes wrong:** Removing methods that had test coverage lowers the numerator; if the removed methods were well-covered (they are, in `test_processor.py` and `test_processor_refactored_methods.py`) the percentage could change. However since the tests that exercised these methods via the public `run()` path will still exercise the service equivalents, coverage should remain stable. +**Why it happens:** Coverage tool counts lines per file; fewer lines means each uncovered line matters more. +**How to avoid:** Run `python -m pytest tests/ --cov-fail-under=91` after each commit. The project currently has 91.1% coverage. +**Warning signs:** Coverage drops below 91.1%. If it does, check whether any test directly calls the deleted private methods and needs updating. + +### Pitfall 5: Inline Import Style Inconsistency +**What goes wrong:** `pdf_extractor.py` currently uses inline (inside-method) imports from the shim. If replacements are made as top-level imports while other imports remain inline, the file becomes inconsistent. +**Why it happens:** Mechanical find-replace without reading the surrounding context. +**How to avoid:** Either replace all five inline imports with inline equivalents (safest, minimal diff) or hoist all of them to top-level in one consistent pass. Do not mix styles in the same commit. + +--- + +## Code Examples + +### Example 1: DeprecationWarning at module level (standard Python pattern) +```python +# Source: Python stdlib docs - warnings module +# In pdf_table_extractor.py, after existing imports: +import warnings +warnings.warn( + "bankstatements_core.pdf_table_extractor is a backward-compatibility shim " + "and will be removed in a future version. " + "Import directly from bankstatements_core.extraction.extraction_facade, " + "bankstatements_core.extraction.validation_facade, or " + "bankstatements_core.extraction.row_classification_facade instead.", + DeprecationWarning, + stacklevel=2, +) +``` + +### Example 2: pyproject.toml filterwarnings addition +```toml +# In [tool.pytest.ini_options] filterwarnings list: +filterwarnings = [ + "ignore:TestResult has no addDuration method:RuntimeWarning", + "ignore::DeprecationWarning:bankstatements_core.pdf_table_extractor", +] +``` + +### Example 3: extraction_orchestrator.py import switch +```python +# BEFORE (line 16): +from bankstatements_core.pdf_table_extractor import extract_tables_from_pdf + +# AFTER: +from bankstatements_core.extraction.extraction_facade import extract_tables_from_pdf +``` + +### Example 4: pdf_extractor.py inline import replacements +```python +# _extract_page method — BEFORE: +from bankstatements_core.pdf_table_extractor import validate_page_structure +from bankstatements_core.pdf_table_extractor import merge_continuation_lines + +# _extract_page method — AFTER: +from bankstatements_core.extraction.validation_facade import validate_page_structure +from bankstatements_core.extraction.validation_facade import merge_continuation_lines + +# _determine_boundaries_and_extract method — BEFORE: +from bankstatements_core.pdf_table_extractor import detect_table_headers +from bankstatements_core.pdf_table_extractor import detect_table_end_boundary_smart + +# _determine_boundaries_and_extract method — AFTER: +from bankstatements_core.extraction.validation_facade import detect_table_headers +from bankstatements_core.extraction.extraction_facade import detect_table_end_boundary_smart +``` +Note: `detect_table_headers` appears at two call sites (lines 187 and 228).

The project has no explicit style rule mandating inline or top-level. + - What's unclear: Whether the team prefers to keep them inline (minimal diff) or hoist them to top-level (cleaner, more conventional). + - Recommendation: Keep inline to minimise diff noise in this refactoring phase. Hoisting can be a separate cosmetic commit. + +2. **Guard test file placement** + - What we know: `tests/test_logging_style.py` already houses style-enforcement tests. Alternatively, `tests/test_architecture.py` is a new file. + - What's unclear: Team preference. + - Recommendation: New `tests/test_architecture.py` — architecture guards are distinct from logging-style guards and deserve a clearly-named home. + +3. **TransactionFilterService — `filter_invalid_date_rows` alias** + - What we know: The RFC mentioned adding `filter_invalid_date_rows` and `has_valid_transaction_date` to `TransactionFilterService`. These names do NOT exist on the service (it has `filter_invalid_dates`, which does the same job). + - What's unclear: Whether new aliases are needed for the RFC to be complete. + - Recommendation: No aliases needed. The private methods on `BankStatementProcessor` being deleted are not replaced by anything — they are dead code. `TransactionFilterService.filter_invalid_dates` already exists and already covers this behaviour.
