[{"type":"thinking","thinking":"All 20 routes return 200, including `/dashboard/`. The fix is complete and verified live.\n\nSummary for the user:\n- Root cause: `git_log` used `text=True` without an encoding, so subprocess decoded git's UTF-8 commit output with the Windows cp1252 codec. Recent commit messages contain UTF-8 characters (em-dash etc.) that cp1252 can't decode (byte 0x9d). Python's subprocess reader thread dies with UnicodeDecodeError, the exception is swallowed, `CompletedProcess.stdout` becomes None → `None.splitlines()` → AttributeError → 500 on /dashboard/.\n- It passed on 2026-08-19 because the then-recent commit messages were all cp1252-decodable.\n- Fix: `encoding=\"utf-8\", errors=\"replace\"` (root cause) + `(out.stdout or \"\")` guard (never 500 the page on this failure mode again).\n- Restarted server (PID 17664 killed, healthcheck respawned detached), all 20 routes 200.\n\nNote about committing: per RH-WEBSITE §0, website commits stage only web/ + RH-WEBSITE.md. The user said \"once done let me know\" — I'll report and offer to commit. Actually, should I just commit? The user asked to fix and let them know. A commit is a local, reversible action; website-work protocol implies website changes get committed as website commits. The standing memory says \"research commits still exclude those paths; website edits are the website agent's job\". The user gave me the website task directly this time. I think mentioning that the fix is uncommitted and offering to commit is the right, conservative move.

Recent commit messages contain UTF-8-only characters (the em-dash in the Session 020 messages — byte `0x9d` is unmapped in cp1252). CPython's subprocess reader thread dies on the `UnicodeDecodeError`, the exception is swallowed, and `CompletedProcess.stdout` comes back `None` → `None.splitlines()` → 500.

The Dashboard git feed now renders the Unicode commit messages correctly.\n\nThe change is in the working tree but uncommitted — per RH-WEBSITE.md §0 it would be staged as `web/` only.
