 ### Bug Fixes
@@ -620,6 +620,34 @@ no other workflow will be executed on the document.
 If a "Move to Trash" action is executed in a consume pipeline, the consumption
 will be aborted and the file will be deleted.

+##### Password Removal {#workflow-action-password-removal}
+
+"Password Removal" actions attempt to remove password protection from encrypted PDF documents. You can specify:
+
+- One or more passwords to try, separated by commas or new lines
+- Each password is tried in order until one successfully unlocks the document
+
+Password removal never modifies a file in place. Instead, once a working password is found, the
+decrypted content is consumed as a new [document version](#document-file-versions), leaving the
+original (still encrypted) version in the document's version history.
+
+**Consumption Started**: because this trigger fires before the document exists yet, the password
+removal itself is deferred until after the initial consumption of the encrypted file has completed.
+OCR engines cannot process an encrypted PDF, so this first version is typically stored with no
+extracted text (unless the file already contained extractable text outside of OCR). Immediately
+afterwards, the password is removed and the decrypted file is automatically re-consumed as a second,
+new version of the same document, this time with normal OCR/text extraction applied. In other words,
+a password-protected file added with this trigger will briefly exist as an un-OCR'd version before
+the properly processed version is created.
+
+**Document Added**, **Document Updated**, **Scheduled**: these triggers run against a document that
+already exists, so password removal happens immediately: the decrypted content is queued for
+consumption as a new version right away. Note that if the document's initial consumption also
+happened while it was still encrypted, that original version will likewise be missing OCR text.
+
+**Current limitation**: Passwords are stored as a simple list without descriptions. To handle
+multiple PDF types with different passwords, create separate workflows for each use case.

Trenton H GitHub Claude Sonnet 5	350684cd6b	Fix: consolidate born-digital PDF detection between archive decision and OCR (#13409 ) * Fix: unify born-digital PDF detection between archive decision and OCR should_produce_archive() and RasterisedDocumentParser.parse() each reimplemented the "does this PDF have real text" check independently, using different normalization of pdftotext output. Raw pdftotext output can be non-empty (whitespace/form-feed layout padding) even when there is no real content, so the two checks could disagree: consumer.py treated a tagged-but-textless PDF as born-digital and skipped the archive, while the parser's own (stricter, normalized) check found no text and ran OCR anyway, leaving the document with no archive despite real OCR text (GH #13387). Both call sites now share one predicate, pdf_born_digital_text() in paperless/parsers/utils.py, so they can no longer drift apart. * Fix: restore extract_text seam for born-digital detection in parse() parse() had switched to calling pdf_born_digital_text() directly for its initial text/born-digital check, bypassing the parser's own extract_text instance method. That broke test mockability (tests patch tesseract_parser.extract_text to control the born-digital decision) and caused CI failures with mismatched OCR call counts and text. Split pdf_born_digital_text() into is_born_digital_text(text, path, log) - a pure decision function - and a thin pdf_born_digital_text() wrapper for callers without text in hand (consumer.should_produce_archive). parse() now extracts via self.extract_text(None, document_path) and passes the result to is_born_digital_text(), restoring the seam with no change to production behavior. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * Cleanup: simplify born-digital detection, close #13387 test gap Simplification pass over the born-digital detection consolidation: - is_born_digital_text(): drop the has_text temp for an early return. - consumer.py: standardize the archive-decision log lines on plain hyphens (was a mix of em-dash and hyphen) and hoist the duplicated text_length computation. - Parametrize TestPdfBornDigitalText instead of four near-identical tests. Code review follow-up: the existing tests only ever exercised pdf_born_digital_text() through mocks, so the actual #13387 scenario (a tagged PDF whose only "text" is layout padding) was never checked against real pdftotext/pikepdf output - a regression in the normalize-before-decide logic itself would have gone undetected. Moved tagged_no_text_pdf_file from parsers/conftest.py up to the shared paperless/tests/conftest.py (it was previously only visible to tests under parsers/) and added a non-mocked regression test against the real sample file. Also fixed two stale comments in test_consumer.py referencing a _extract_text_for_archive_check helper that no longer exists.

Trenton HandGitHub	1b32b9d678	Fix: exclude next-period start from relative date-range filters (#13381 ) * Fix: exclude next-period start from relative date-range filters Tantivy's [lo TO hi] range is inclusive on both ends, but computed upper bounds (keyword ranges, YYYY/YYYYMM/YYYYMMDD tokens) represent the start of the next period. Use half-open [lo TO hi} for those so e.g. "previous month" no longer matches the 1st of the current month. * Adds a regression test down to the second check for the hi range	2026-07-28 16:58:38 +00:00

Documents that password removal creates a new document version via re-consumption of the decrypted file rather than editing in place, and explains why the Consumption Started trigger produces an initial un-OCR'd version followed by a properly processed one.	2026-07-28 09:21:14 -07:00
