The second string I deleted myself

The release build for AudiobookMaker (a Windows app that turns PDFs and EPUBs into audiobooks with text to speech) died on a 404 and no release went out. The build downloads ffmpeg from a third-party build repo, pinned to the exact filename ffmpeg-n7.1-latest-win64-gpl-7.1.zip. That project deletes a stable line once it moves on, and one day it moved on. A comment right above the step asked whoever passed by to bump the pin. Nobody ever did.

The fix downloads the checksum file first, since it is both the integrity check and the list of what actually exists. If the pinned name is missing, the build takes the newest stable Windows build the manifest does list, and warns loudly to update the pin. Verification against the published hash is unchanged. I tested both paths against the live manifest: the pin resolves, and without it the fallback picks the next version up.

The second break was mine. The release notes used to be hardcoded inside the CI workflow, so every release after the first shipped notes for the wrong release. I moved them into a file in the repo, and the move dropped a literal ### What's new heading. Existing users update through an in-app button, beside a “what changed” panel built from the release notes. Its reader began at that exact heading and stopped at the next heading of any kind. Heading gone, panel empty. On GitHub the notes looked perfect. Only the app saw nothing. I found it by checking what the app renders instead of what GitHub shows.

It got worse three more times, each time in the fix for the last one. I made the reader stop at any heading beginning “Installation” or “CLI”. This project ships a CLI. A section honestly titled “CLI gets a resume flag” would count as the install section, and everything after it would vanish. I added an end marker but left the old guesswork running beside it. An ordinary --- line still cut the notes off mid-way. I made the marker the only terminator, and a release whose marker went missing showed the user install instructions and a SHA-256 hash as news. The version that survived: install headings always end the notes, and the weaker markers count only when no explicit marker exists. Each round I re-read all ten published release bodies, the ones installed apps parse. For users on an older build the panel went from 0 characters to 372.

Both fixes have the same shape. Something quietly depended on an exact string, and one day the string was gone. A stranger deleted the first. The second I deleted myself, from my own app.
