Decision Model

SCS does not decide what to write. It records a human decision and keeps the evidence beside it.

GOS is supporting, not a verdict

scs score computes:

n_sv   = sv / max(sv for the site across all workspaces) * 100
n_kd   = kd
gos    = n_sv * (100 - n_kd) / 100
gos_tier = P1 / P2 / P3 / P4

gos_tier is a band, not a priority. It does not set decision, does not set status, and does not block a keyword. A low-GOS keyword can be go when it fills a cluster gap or carries high business value; a high-GOS keyword can be no when competition, knowledge, experience, or E-E-A-T fit is poor.

note

The old priority column was renamed to gos_tier to stop it being read as a verdict. Existing data is migrated automatically by scripts/migrate_schema.py.

Decision fields

Field	Values	Purpose
decision	go, hold, no	The human verdict
decision_reason	text	Why
decision_factors	pipe-separated	competition, knowledge, experience, eeat, business_value, cluster_gap, existing_page, effort
decided_by	text	Person
decided_on	ISO date	When

Gate

A keyword can move to Selected only when decision=go. scs check enforces this. The decision is recorded before the brief, so the writer does not spend time on a keyword the operator has not approved.

Cluster-first selection

The cluster plan is the primary planning unit. clusters.csv can be populated from Researched onward, before a keyword is Selected. This lets you see the pillar, cluster, and supporting gaps first, then decide which page to produce.

• kc_type: Topic, Pillar Page, Keyword Cluster, Sub Topic, Supporting
• pillar_pid / parent_pid: the cluster structure
• coverage_status: planned, in_progress, covered, gap, not_needed
• cluster_priority: P0–P3
• entity_coverage: pipe-separated entities the page should cover

A cluster gap or a strategic pillar can justify a go even when GOS is low.

What SCS will not do

• It will not auto-select a keyword from GOS.
• It will not auto-approve a brief.
• It will not publish live.
• It will not treat a reviewer name as a QA pass.

Those are human decisions, recorded in the CSV and enforced at the gates.
