Posts External Link Status — Phase 4 Baseline (auto-generated)
This document records known broken or flaky external links in pages/_posts/
after the Phase 4 link-repair pass. Internal links: 282/282 OK when validated
against the built _site/ (run lychee --offline --base "$PWD/_site").
External link rot is an ongoing maintenance burden — these entries are acknowledged and tracked, not necessarily considered actionable in the cleanup PR.
Validation command
lychee --no-progress --format json --base "$PWD/_site" \
--max-concurrency 10 --timeout 15 --max-retries 1 \
--accept '200..=299,403' \
pages/_posts/**/*.md

Recommended follow-ups (post-merge, not blocking)
-
creative-experimental/2025-07-03-music-resources-free-sheet-music.md: 12 of 19 broken links live in this single “list of resources” post that is heavily decayed. Recommended action: prepend an editor’s note linking to a Wayback Machine snapshot, OR mark the post as archived/historical, OR replace each URL with itshttps://web.archive.org/web/*/<url>mirror. -
Azure timeouts: Consider switching to canonical short URLs (
https://azure.microsoft.com/en-us/products/devops/) which sometimes respond faster under automated probes. -
Other dead links: One-by-one review against current vendor docs (jekyllrb.com URLs change with releases; YouTube videos disappear).
