From d94a8cedc0cc1b5567fc282b44f8a16257fd5ad5 Mon Sep 17 00:00:00 2001 From: "SentryAgent.ai Developer" Date: Sat, 28 Mar 2026 14:28:55 +0000 Subject: [PATCH] =?UTF-8?q?docs:=20DevOps=20documentation=20=E2=80=94=20co?= =?UTF-8?q?mplete=20docs/devops/=20set?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the full devops-documentation OpenSpec change implementation. Separate from docs/developers/ — serves a different audience (operators, not API consumers). docs/devops/: - README.md — index and system overview - architecture.md — components, ports, data flow, Redis key patterns - environment-variables.md — all 7 env vars (required + optional, formats, .env example) - database.md — 4-table schema, indexes, constraints, migration runner - local-development.md — docker-compose setup, health checks, startup, Dockerfile gap noted - security.md — RSA key generation/rotation, CORS, bcrypt, secret storage guidance - operations.md — startup order, graceful shutdown, log reference, troubleshooting QA gates: 48/48 tasks complete. All env vars verified against source. All table names verified against migrations. All ports verified against docker-compose.yml. All internal links resolve.
