nx_deploy.nx

nx_deploy.nx -- the team's SOVEREIGN deploy-with-rollback capability (operator: pushing site updates with rollback must be a bits-up Nishi capability, layer 8 up, NO 3rd party, S-class-EXCEED practices). The transfer is the sovereign ssh_put_file (proven live on the NAS, no scp); this module encodes the SAFE-DEPLOY decision logic that wraps it, the practices a production deploy must follow: 1. BACKUP the current artifact BEFORE any swap (never deploy without a rollback point) 2. ATOMIC SWAP (write .new, then rename -- never a half-written live file) 3. HEALTH-CHECK after swap (is the service actually up + serving?) 4. ROLLBACK automatically if the health-check fails (restore the backup) 5. SOVEREIGN TRANSFER (ssh_put_file over CHANNEL_DATA, not scp) A deploy NEVER touches production unless a backup exists AND the transfer verified. license_tier: ORIGINAL
