Diagrams Created

Diagram 1: squad-architecture

• File : attachments/squad-architecture.html
• Theme : var-clear
• Pattern : hub-tiered-domains (adapted)
• Template source : 4_templates/_diagrams/architecture/hub-tiered-domains.html
• Corrections applied : Correction #1 (white cards on albatre for 3-level contrast per DK-03, DK-05)

Design Rationale (MANDATORY)

Theme choice : Why var-clear? -> var-clear chosen because the article is a news piece targeting DevOps practitioners. Educational/informational tone benefits from light, approachable background. Article.css provides the opaque white-to-albatre gradient card effect, ensuring visibility.

Layout choice : Why vertical hub + grid + shared output? -> The Squad architecture has a natural top-down hierarchy: coordinator distributes to specialists, specialists converge on shared output. Vertical flow (top to bottom) mirrors the data flow described in the article. The 3-column grid for agents reflects their parallel nature (all equal, all independent).

Color decisions :

• Coordinator block: marine bg + chartreuse icon -- marine signals authority/hub role, chartreuse icon draws attention to the central routing function
• Agent cards: white (#FFF) with empire green accent bar (border-top) -- DK-03 (Gestalt Common Region): white cards on albatre canvas create clear grouping. Empire accent bars categorize them as "specialist" tier
• "thin router" tag: chartreuse text on marine bg -- Von Restorff (DK-04) applied subtly to label the coordinator's key characteristic
• Cross-review zone: dragee bg with dashed border -- dashed border signals a protocol/rule (not a container), dragee provides visual differentiation from the solid cards
• Shared output (.squad/decisions.md): marine bg + chartreuse text -- DK-02 (Figure/Ground): dark zone at bottom anchors the conclusion/convergence point
• Amplifier: empire green on albatre -- standard var-clear amplifier pattern

Contrast approach : Which DESIGN_KNOWLEDGE principles applied? -> DK-03 (Common Region): white cards on albatre canvas for agent grouping -> DK-05 (3-level contrast): canvas albatre > white agent cards > marine shared output -> DK-04 (Von Restorff): the "thin router" pill tag in chartreuse isolates the key concept -> DK-06 (Accent bars): empire green border-top on agent cards categorizes without heavy backgrounds -> DK-13 (Text opacity min 0.9): all informative text at opacity 0.9 minimum

What I considered but rejected : -> Considered var-deep (marine) for the full diagram to give it a "technical/premium" feel, but rejected because the article is a news piece -- educational clarity matters more. Also, the 3 agent cards need to be visually distinct from the coordinator, which is harder on a dark background. -> Considered using diagram-flow (horizontal) for the agents, but grid-3 better represents their parallel/independent nature. Flow implies sequential processing. -> Considered a more complex diagram with bidirectional arrows showing cross-review between each pair of agents, but this adds visual noise for a news article. The dashed cross-review bar communicates the concept more cleanly.

QA Instructions

Screenshots to take (for article-qa-tester):

1. Full page desktop (1280px) -- verify diagram renders inside article after the first bullet list
2. squad-architecture -- zoom at .diagram-inline -- verify card effect from article.css (gradient + shadow)
3. squad-architecture mobile (375px) -- verify agents-row collapses to single column
4. Verify includeDiagrams: true in frontmatter loads diagrams.css
