Implements process_pdf and extract_bank_statement on Provider::Anthropic
using the native `document` content block — no rasterization, no text
pre-extraction.
- Provider::Anthropic::PdfProcessor classifies the document, summarizes
it, and extracts statement metadata via a forced report_document_analysis
tool whose input_schema mirrors the existing Provider::Openai output
(document_type from Import::DOCUMENT_TYPES, summary, extracted_data).
- Provider::Anthropic::BankStatementExtractor returns the same
{ transactions, period, account_holder, account_number, bank_name,
opening_balance, closing_balance } shape via report_bank_statement so
downstream pdf_import code is provider-agnostic.
- Both attach the PDF as
{ type: "document", source: { type: "base64", media_type: "application/pdf", data: <b64> } }
— Claude 3.5+ / 4.x accept this natively (up to 32MB / 100 pages).
No pdf-reader, no pdftoppm, no chunking for typical statements.
- supports_pdf_processing? (introduced in PR 1) already returns true for
claude-* models, gating process_pdf with a clear error otherwise.
- Cost ledger rows are persisted via the shared UsageRecorder concern,
including cache_creation/cache_read tokens.
Tests verify the document block shape, tool_choice forcing, normalized
document_type for unknown classifications, transaction normalization
(date / amount / reference → notes), and the missing-tool_use error
path. Blank pdf_content raises before any client call.
Stacked on #1984 (PR 2/5). 4/5 pgvector RAG next.
