root b30a4f0d32 Diagram generation: ref-arch-driven procedure + spec validator + KB enrichment 
The diagram path now follows a documented standard procedure (lookup
the closest Oracle Architecture Center reference → confirm components
→ author absolute_layout → spec validator → render → visually verify)
and ships persistent guardrails so layout regressions can't recur.

Persistent procedure changes (apply to all users, all sessions):
- tools/diagram_spec_validator.py — geometry checks (CONTAINER_TOO_THIN,
  CONTAINER_PADDING_VIOLATION, LABEL_OVERFLOW_PARENT) run BEFORE either
  renderer (drawio + PPTX). Catches the subnet-collapse / label-overflow
  bugs that the post-render drawio validator missed.
- tools/oci_diagram_gen.py + tools/oci_pptx_diagram_gen.py — call the
  spec validator before emitting any output. Adds mysql / mysql_heatwave
  type aliases.
- tools/archcenter_pattern_lookup.py — scores against cached page
  descriptions (not just the 1-line summary), supports --queries for
  multi-fragment composition, and applies synonym expansion via
  kb/architecture-center/synonyms.yaml so "LB HA cross AD" matches
  "load balancer high availability availability domain".
- kb/architecture-center/synonyms.yaml — canonical synonym table
  (load balancer, autonomous database, data guard, …) used by the
  lookup scorer.

KB enrichment:
- tools/archcenter_description_fetcher.py + 121 cached _description.md
  under kb/diagram/assets/archcenter-refs/<slug>/. Removes the runtime
  dependency on docs.oracle.com when authoring specs and feeds the
  pattern-lookup scorer.
- 110+ cached .drawio / .svg / .png references for offline reuse,
  plus the OCI Toolkit v24.2 import (kb/diagram/assets/oci-toolkit-drawio).

Documentation:
- docs/skill/output-formats.md — new "Standard diagram-generation
  procedure (MANDATORY)" + geometry rules + the new validator entry.
- SKILL.md option 2 — references the mandatory procedure.
- README.md — describes the spec validator, archcenter_pattern_lookup
  and description fetcher, and updates the KB-health table.

Tooling that backs the procedure (cumulative across recent sessions):
tools/archcenter_case_runner.py, archcenter_batch_driver.py,
archcenter_zip_downloader.py, drawio_visual_validator.py,
drawio_fidelity_eval.py, harvest_drawio_icon.py, import_oci_library.py,
oci_pptx_diagram_gen.py, oci_pptx_render.py, refresh_pptx_icon_index.py.

# ============================================================
# KEY VISUAL RULES (from toolkit analysis)
# ============================================================
design_rules:
# Container rules (confirmed from OCI Toolkit v24.2 + 7 Oracle Architecture Center reference diagrams)
- "VCN and Subnet borders are ALWAYS dashed burnt orange (#AE562C) — this is the signature Oracle visual"
- "VCN border is strokeWidth=2, Subnet border is strokeWidth=1"
- "Region containers are the ONLY ones with solid background fill (#F5F4F2)"
- "Tenancy and Compartment containers are dashed gray, NO fill"
- "VCN and Subnet labels are BOLD, ORANGE (#AE562C), left-aligned inside the container (top-left)"
- "Subnet labels sometimes include CIDR notation below in smaller text (10pt gray)"
# Visual hygiene rules — observed from OCI Toolkit v24.2 reference
# diagrams + diagram best practices. Added 2026-04-25 after Diego
# flagged labels overlapping connectors and containers stacked
# without breathing room.
# Connector labels — verified from OCI Toolkit v24.2 slide 11 "Connector Labels":
# "Use connector labels to distinguish different types of logical connections and relationships."
# "Use 8pt font size and Bark color for label text."
# "Place connector labels on the horizontal portions of a line whenever possible."
# "Center connector labels on the connector line."
- "Connector labels are a PROPERTY of the connector edge, not a standalone text shape — set them on the connection's `label` field, not in a separate labels[] entry"
- "Connector label typography: fontSize=8 (raw points), fontColor=#312D2A (Bark), Oracle Sans"
- "Center the label on the connector — drawio's edge labels carve a small whitespace cutout in the line so text remains legible without a white background box"
- "Place labels on the HORIZONTAL portion of the line whenever possible (avoid placing on a vertical segment)"
- "Do NOT use a separate text shape and labelBackgroundColor=#FFFFFF — that's a workaround that breaks if the line moves"
- "Container minimum padding: 18px between an inner container's bottom edge and its parent's bottom edge (so nested borders don't visually merge)"
- "Container minimum padding: 12px between an inner container's top edge and the parent container's label baseline"
- "Vertical gap between sibling subnets inside a VCN: ≥20px (Oracle ref average)"
- "Service icons inside a subnet: ≥18px from the subnet top edge so the subnet label doesn't visually collide with the icon"
- "Two service icons in the same row: ≥30px horizontal gap (Oracle ref average)"
- "When two ADs span the same subnet horizontally, leave ≥25px gap between AD right and AD left so the subnet's vertical band reads as continuous"
# VCN/Subnet corner markers — clarification 2026-04-25
# Per OCI Toolkit v24.2 slide 18 ("Grouping"):
# "VCN, routing table, and security list icons are used at half size as
# labels to differentiate the VCN and subnet."
# OPTIONAL ("if they add clarity") but the documented standard. Many
# Architecture Center references omit them on simple diagrams; reference
# diagrams with multiple VCNs/subnets typically use them.
- "OPTIONAL: VCN containers may carry a half-size vcn_icon at the top-right corner"
- "OPTIONAL: Subnet containers may carry a half-size route_table_and_security_list icon at the top-right corner"
- "Authoring rule (absolute_layout): add as a service with type=route_table_and_security_list at (container.x + container.w - 24, container.y - 4) with w=h=22 for VCN, 18 for subnet"
- "DEFAULT: ONE marker per VCN, NOT per subnet. Six markers in a 2-region diagram is visual noise that competes with the data flow — the validator's EXCESSIVE_CORNER_MARKERS warns at ≥6"
- "Skip these markers on simple diagrams — they reduce clutter only when there is a single VCN/subnet"
# Connection edge ports — added 2026-04-25 after Diego flagged
# "colita / semicírculo al inicio de las flechas" caused by
# mismatched waypoints with explicit ports.
- "Use exit_x/exit_y/entry_x/entry_y on connections to disambiguate parallel edges from the same source (e.g. Local DG and Remote DG both leaving exa_primary)"
- "Distinct exit_y values: 0.4 vs 0.8 routes the two arrows on different horizontal bands"
- "When using explicit ports, DO NOT also pass waypoints — drawio auto-routes orthogonally between ports. Mismatched waypoints behind the exit port make drawio draw a curve-loop 'tail' at the source"
- "The renderer drops waypoints automatically when ports are explicit, with a stderr warning, but the spec author should not author both"
- "Auto-port detection in the renderer is also disabled when waypoints are present: if the spec author chose explicit waypoints, they own the route — adding auto-ports on top would re-introduce the curve-tail bug for every connection in the spec"
# Multi-cloud diagrams — added 2026-04-25 (Diego: "si usa AWS-branded
# cuando sea necesario claro, no solo ec2 tambien los demas componentes")
- "Multi-cloud diagrams: use the official provider stencil (AWS, GCP, Azure) for components that belong to that cloud — NOT an OCI stencil. Spec field: cloud_icon (e.g. cloud_icon: ec2, cloud_icon: rds, cloud_icon: s3). The renderer maps to mxgraph.aws4.* / mxgraph.gcp2.* via _aws_icon_style / _gcp_icon_style"
- "Available AWS keys: ec2, eks, ecs, lambda, rds, aurora, dynamodb, s3, elb, alb, cloudfront, vpc, direct_connect, route53, sqs, sns, kinesis, api_gateway, cognito, iam, cloudwatch, sagemaker, bedrock (see AWS_ICONS in tools/oci_diagram_gen.py — extend by adding entries to that table)"
- "Available GCP keys: gce, gke, cloud_sql, bigquery, cloud_storage, cloud_run, cloud_functions, pub_sub, cloud_dns, cloud_load_balancing, cloud_cdn, cloud_iam, cloud_armor, spanner, firestore, memorystore, ai_platform, vertex_ai, dataflow, dataproc, composer (GCP_ICONS table)"
- "Available Azure keys: vm, virtual_machine, vmss, aks, app_service, function, container_instance, sql_database, cosmos_db, blob_storage, data_lake, vnet, load_balancer, application_gateway, expressroute, vpn_gateway, azure_dns, front_door, key_vault, active_directory, sentinel, monitor, log_analytics, event_grid, service_bus, api_management, openai, ml_studio (AZURE_ICONS table — added 2026-04-25)"
# Multi-cloud CONTAINER styles (added 2026-04-25 — Diego: "vpc de aws
# por ejemplo no tiene una forma en particular?"):
- "Multi-cloud containers: spec a container with `cloud: aws|gcp|azure` plus the standard `type` field, and the renderer applies the cloud-native style (color, dash, font). Falls through to OCI style if no cloud match"
- "AWS container types: region, vpc, subnet, subnet_public, subnet_private, az — colors per AWS Architecture Icon Guidelines (#232F3E text, #8C4FFF VPC, #7AA116 public subnet, #00A4A6 private subnet)"
- "GCP container types: project, region, vpc, subnet — Google blue #4285F4, lighter #669DF6 for subnets"
- "Azure container types: subscription, region, vnet, subnet — Azure #0078D4 throughout, Segoe UI font"
- "When unsure, default to OCI stencil (type=...) rather than guessing a wrong AWS key — the visual is OCI-compatible and clearly distinguishable from native AWS shapes"
- "Visual-weight parity: AWS/GCP filled-square stencils render ~72% of the spec bbox so they match the visual weight of OCI line-art stencils at identical w/h. The renderer applies this scaling automatically when cloud_icon is set"
# CIDR conventions — added 2026-04-25 (Diego: "le agregaste cidr a la
# network y eso no lo pedi")
- "Do NOT add CIDR notation to subnet/VCN labels unless the user explicitly requested it. The label is just 'VCN', 'DB Subnet', etc. CIDRs are an implementation detail that clutters high-level architecture diagrams"
- "Same rule for IP addresses, port numbers, instance counts, SLA numbers — add only what the user asked for, nothing else"
# Service icon rules (confirmed from 7 Oracle Architecture Center reference diagrams)
- "Service icons are LINE ART / OUTLINE style in teal (#2D5967) — NOT filled colored rectangles"
- "Service icons do NOT have colored background boxes when rendered as OCI library stencils"
- "Service label is BELOW the icon, centered, in dark charcoal (#312D2A)"
- "Service label font size is 10-11pt (NOT 14pt) — confirmed from Oracle ref arch diagrams"
- "Total service block height (icon + label) should be ~90px for OCI services, not 45px"
# External cloud rules (confirmed from multicloud Oracle reference diagrams)
- "Azure containers use SOLID blue border (#0078D4) with light blue fill (#EBF5FF)"
- "Azure container labels are bold, dark blue (#0050A2)"
- "GCP containers use solid green border (#34A853) with light green fill (#E8F5E9)"
- "AWS/generic containers use dashed muted gray border (no specific Oracle style defined)"
# Oracle Services Network panel (confirmed from hub-spoke, OKE, lakehouse Oracle diagrams)
- "Oracle Services Network is a right-side dashed gray panel containing managed OCI services"
- "Services in Oracle Services Network are NOT in any VCN/Subnet — they float in the panel"
- "Use compartment-style container with oracle_services_network label for this panel"
- "OSN panel has NO fill (transparent) — dashed gray border only"
# Flow differentiation — Oracle uses line patterns, NOT numbered circles
- "Oracle differentiates flow types by DASH PATTERN, not numbered circle badges"
- "Ingest: dotted fine; Transform: dash-dot; Curate: fine dotted; Analyze: dashed"
- "Flow labels are text strings on the arrow path ('Process and store', 'Deploy model')"
- "A legend box at the bottom explains the line patterns if multiple flow types exist"
# Connector and typography rules
- "Service blocks use solid fills with NO stroke (strokeColor=none)"
- "Text is NEVER pure black — always charcoal #312D2A"
- "Font is Oracle Sans (falls back to Segoe UI)"
- "Icons are composite multi-layer Visio stencils in the OCI Library.xml"
- "ALL connectors use charcoal #312D2A — same as text, NOT colored"
- "Connectors use open arrow tips (endArrow=open, endFill=0) — never filled blocks"
- "Connectors use orthogonal routing (edgeStyle=orthogonalEdgeStyle) — never diagonal"
- "Arrow size is small and consistent (endSize=6)"
- "Dashed lines differentiate replication/migration from standard flows"
- "FastConnect is bidirectional (startArrow=open + endArrow=open)"
- "Oracle DB-related services use copper #AA643B"
- "Integration/messaging services use purple #804998"
- "All other OCI services use teal #2D5967"
