Title

Standards Scope Segmentation — Universal, Work, Personal

Requested By

Evan Rosado

Date Submitted

2026-04-10

Priority

P1 — framework architecture

All 20 standards applied uniformly with no distinction between CHLA work (hospital infrastructure, CAB processes, iTrack, compliance) and personal (Domus Digitalis home lab, self-managed systems). These are fundamentally different environments with different constraints, risk tolerances, and operational processes.

Projects already had clean separation (pages/projects/chla/ vs pages/projects/personal/). Case studies already used :context: work | personal. Standards needed to follow — they were the last gap in the scope segmentation model.

What Changed

New Attribute: `:std-scope:`

Added to every standard page file alongside existing :std-id:, :std-status:, :std-domain:.

Scope Value Meaning

Scope Value	Meaning
`universal`	Applies to both work and personal — foundational practices
`work`	CHLA-specific — compliance, team processes, CAB, hospital infrastructure
`personal`	Domus Digitalis — home lab, self-managed infrastructure

universal

Applies to both work and personal — foundational practices

work

CHLA-specific — compliance, team processes, CAB, hospital infrastructure

personal

Domus Digitalis — home lab, self-managed infrastructure

Existing Standards Tagged

All 20 existing standards tagged :std-scope: universal — they define how to work, not where. The work/personal distinction comes from new scoped standards.

Three New Standards Created

ID	Standard	Scope	Content
STD-021	Change Advisory Board (CAB)	work	iTrack fields, approval workflow, change lifecycle, personnel roles, scheduling
STD-022	CHLA Network Operations	work	ISE policy changes, VLAN provisioning, trunk config, 802.1X closed mode, verification commands
STD-023	Home Lab Infrastructure	personal	LUKS, AppArmor, UFW, kernel hardening (8 sysctl checks), systemd sandboxing, key management, security dashboard

Scope

In Scope

:std-scope: attribute added to all 23 standards (20 existing + 3 new)
STD-021, STD-022, STD-023 created with full content
Registry updated with Scope column
Nav entries added with scope labels
