Harden production deploy: prune .env backups, document ENV source-of-truth - #40
Conversation
…truth The workflow ENV-sync now keeps only the 10 most recent /opt/smartsht/.env.bak-gha-* backups instead of accumulating them unbounded. Also documents that the GitHub ENV secret is authoritative (every auto-deploy overwrites the server .env from it), warns against hand-editing the live file, and notes how to verify the loaded env via /health or the boot log.

Hey - I've reviewed your changes and they look great!
Sourcery assessment
Needs a human reviewer. Each deploy now irreversibly deletes older production .env backups, so a mistaken prune or an unanticipated need to recover an older configuration cannot be undone by reverting the workflow. The loss is bounded to matching backup copies, but the deleted files are not restored by a subsequent deploy.

Prune backups when .env is absent.
The pruning command remains inside the [ -f /opt/smartsht/.env ] block. If the live file is missing but stale .env.bak-gha-* files already exceed 10, this sync creates the new file without pruning them. Move the pruning block after fi so every sync enforces the documented limit.

Move the keep-last-10 prune outside the [ -f /opt/smartsht/.env ] guard so stale backups are pruned on every sync, including runs where the live .env file does not exist. Pruning depends only on the .bak-gha-* files, not the live file.
Summary
Hardening for the GitHub Actions production deploy pipeline. No runtime code changes — workflow + docs only.
Changes
Sync ENVstep now keeps only the 10 most recent/opt/smartsht/.env.bak-gha-*backups instead of accumulating them unbounded on the server across deploys.ENVsecret is authoritative: every auto-deploy (merge tomain) overwrites/opt/smartsht/.envfrom it. Added a header warning in the workflow and a stronger note indocs/DEPLOY.mdcautioning against hand-editing the live file (silently reverted next merge) and describing how to verify the loaded env via authenticated/health(runtime.envFile.path) or the boot log.Context
While reviewing the deploy setup we confirmed the server env-loading path is already correct: the workflow symlinks
/opt/smartsht/.env→current/server/dist/server/.env, which is exactly the second candidateloadEnv.tsresolves in the compiled build. No code fix was needed there — this PR only hardens operations and documentation around it.Testing

Harden production environment synchronization by bounding backup retention and documenting the GitHub secret as the deployment source of truth.
