This replaces the blocked history in PR #3 with one properly attributed, signed/DCO commit. The owner personally reviewed and approved PR #3 in the release session. **No file changes from the approved candidate:** bothbaee14f492ande605df62c4have exact Git treea85912cbad. Original PR #3 and its commits are preserved for review history. Historical commits were locally signed but GitHub reported no_user; protected merge checks those introduced commits even for squash merging. This commit resolves attribution without bypassing or weakening signature rules. The reader, Settings, themes, source highlighting/split, live reload, file associations, Print/PDF, About credits, toolbar/footer/editor fixes, user-first README/screenshots and developer guides are exactly the approved implementation. Stable/dev separation and protected Azure signing caller are unchanged. Evidence: - Approved treebaee14f/ CI38285775463 passes all checks. Downloaded focused29/29, published111/111, stable110/110 and dev110/110 TRXs have zero failures/skips. Core coverage100% lines/98.86% branches; actual update/restart/coexistence/default-preservation receipts verify. - New single-commit hooks, online workflow security, signing and DCO pass. GitHub must rerun all required checks on this commit; results are not copied across SHAs. - Live repository setup validates18 Actions-bound checks, with only fuzzing added and all prior protections preserved. - OpenSSF project15417 is now owner-reviewed and saved at70% under owner-confirmed CDLA-Permissive2.0. This is an in-progress assessment, not a passing badge. - Production CI OIDC and signed1.0/dev publication remain required; local representative signing is not CI proof. Substantial AI assistance: Codex (GPT-6). Supersedes PR #3. Release work remains tracked in #33.

markdownViewr resources, frontmatter and navigation behavior
This Windows application is based on Darin Kelkhoff's macOS markdownViewr. Original project: darinkelkhoff/markdownViewr. Author website: kelkhoff.com. Windows issues and support belong to the Windows repository; this attribution does not imply endorsement.
Per-window reading zoom bounds/steps and native minus/percentage/plus behavior are adapted from ContentView.swift and MarkdownViewrApp.swift. Font-size scaling is adapted from ThemeManager.swift; original theme JSON and line height stay unchanged.
Frontmatter delimiter/metadata display behavior is adapted from MarkdownDocument.swift at the same pinned commit. Raw-HTML highlight/superscript/underline behavior and the metadata/body subscript boundary are also adapted from that file. Windows applies these patterns only to tokenizer-identified visible text, preserving attributes, comments, authored code and original source positions before passive sanitation. Named editor identities, list ordering/removal and file/folder opening semantics are adapted from EditorConfig.swift there; Windows uses bounded .exe choices and one literal process argument. Vim sequence/navigation, nested source folding and heading-anchor scroll interpolation semantics are adapted from Resources/template.html there, with native Windows Ctrl+F, literal source controls and input focus guards. The 20 original JSON themes are copied unchanged from Darin Kelkhoff's markdownViewr at commit 6d08bc9d27d7d7b2c2fa95bb282da330b8cf9021.

The print defaults, Clean Printing palette and print-media layout rules in
Core/Printing/ and the native print adapter are adapted from Darin Kelkhoff's
MIT-licensed markdownViewr (6d08bc9), with original/adaptation copyright headers
retained. Actual PDF acceptance uses the built-in Windows PDF API; no additional
PDF renderer/parser package is shipped.
