The vault sync re-escaped CLIENT_JWT_PRIVATE_KEY, Compose turned it into lines ending in a backslash, and /.well-known/jwks.json 500d after the 2026-10-10 deploy, breaking MyChart token exchange. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

/.well-known/jwks.json and jwks-sandbox.json returned 500 (ERR_OSSL_PEM_NO_START_LINE) after the 2026-10-10 deploy recreated the container. app.env held CLIENT_JWT_PRIVATE_KEY with one escape level too many, so Compose produced lines ending in a backslash. Epic fetches this JWKS on every private_key_jwt token exchange, so the bug broke MyChart connects.
Hotfixed on dev2 by correcting app.env. This change collapses any run of backslashes before
nor a newline, so the next vault sync can't break it again. Verified that a raw PEM and three escaped variants all parse.🤖 Generated with Claude Code
