+

+
+This project ships `.codex/config.toml` which enables `network_access = true`
+for the workspace-write sandbox. This is required so `make venv` can reach
+PyPI. If you see `No matching distribution found for pyyaml`, the config file

+Codex loads `.codex/config.toml`.

-## Running Tools
+## Environment Setup
+
+Before running ANY Python tool, ensure dependencies are installed:
 
 ```bash
-# Generate slide deck (default output)
+make venv && source .venv/bin/activate
+```
+
+The Makefile auto-detects the best available Python (3.12 > 3.11 > 3.10 > python3).
+**Always use `make <target>` to run tools** — this guarantees the correct Python with all dependencies.
+
+## Running Tools
+
+Prefer `make` targets. For custom specs, activate the venv first (`source .venv/bin/activate`), then use `python`:
+
+```bash
+# Standard targets (recommended)
+make deck                    # slide deck with sample spec
+make diagram                 # architecture diagram

+## Coding Guidelines
+
+### 1. Think Before Coding
+Don't assume. Don't hide confusion. Surface tradeoffs.
+- State your assumptions explicitly. If uncertain, ask.
+- If multiple interpretations exist, present them — don't pick silently.
+- If a simpler approach exists, say so. Push back when warranted.
+- If something is unclear, stop. Name what's confusing. Ask.
+
+### 2. Simplicity First
+Minimum code that solves the problem. Nothing speculative.
+- No features beyond what was asked.
+- No abstractions for single-use code.
+- No "flexibility" or "configurability" that wasn't requested.
+- No error handling for impossible scenarios.
+- If you write 200 lines and it could be 50, rewrite it.
+
+### 3. Surgical Changes
+Touch only what you must. Clean up only your own mess.
+- Don't "improve" adjacent code, comments, or formatting.
+- Don't refactor things that aren't broken.
+- Match existing style, even if you'd do it differently.
+- If you notice unrelated dead code, mention it — don't delete it.
+- Remove imports/variables/functions that YOUR changes made unused.
+- Every changed line should trace directly to the user's request.
+
+### 4. Goal-Driven Execution
+Define success criteria. Loop until verified.
+- "Add validation" → write tests for invalid inputs, then make them pass.
+- "Fix the bug" → write a test that reproduces it, then make it pass.
+- "Refactor X" → ensure tests pass before and after.
+- For multi-step tasks, state a brief plan with verification steps.
+
 ## Welcome Flow
 
 When the user starts a conversation without providing discovery notes or a specific request (e.g., a greeting like "hola", "hey", or empty context):
 
 **MANDATORY:** Use the `Read` tool to open `SKILL.md` and read the entire `## Welcome Flow` section **before** showing anything to the user. Reproduce the welcome banner and the 14-option capability menu **verbatim** from that file. Do NOT paraphrase, reorder, summarize, translate, or reconstruct the menu from memory, folder structure, or prior conversations. If `SKILL.md` cannot be read for any reason, tell the user instead of improvising a menu.
 
-**Pre-flight check (also defined in SKILL.md):** Before showing the welcome message, run `python tools/kb_freshness.py --check --json`. If `stale_count > 0`, follow the banner-and-prompt logic in SKILL.md § Welcome Flow → Pre-flight. If the tool errors, silently skip the banner — never block the user.
+**Pre-flight check (also defined in SKILL.md):** Before showing the welcome message, run `make kb-check 2>/dev/null`. If `stale_count > 0`, follow the banner-and-prompt logic in SKILL.md § Welcome Flow → Pre-flight. If the tool errors, silently skip the banner — never block the user.

+
+**When it matches:** "ExaCS X11M BYOL, N ECPUs, M TB storage, no DR" — customer-managed
+Oracle Database on dedicated Exadata hardware, BYOL licensing.
+
+**SKUs:**
+
+| SKU | Component | Typical qty |
+|-----|-----------|-------------|
+| `B90777` | Exadata Infrastructure — Base System | `1` per rack |
+| `B110627` | Exadata Database Server — X11M | `2` (Base/Quarter) — adjust per rack config |

+
+**When it matches:** "ADB Dedicated, N ECPUs, M TB, BYOL" — Autonomous Database running
+on dedicated Exadata infrastructure.
+
+**⚠️ Gotcha that burns tool calls:** ADB-Dedicated has **no separate infrastructure
+SKUs** in the catalog. It reuses the same Exadata dedicated infra SKUs as ExaCS
+(`B90777`, `B110627`, `B110629`) plus the same Exadata ECPU SKU (`B110631`/`B110632`).
+The Autonomous-vs-customer-managed distinction is a tenancy-level configuration,
+not a billing line item. Do not search for `autonomous_dedicated` SKUs — they do
+not exist.
+
+**SKUs:** identical to Recipe 1.

+## Recipe 3 — Autonomous Database Serverless (ADB-S) + Block Volume + FastConnect
+
+**When it matches:** "ADB-S ATP, N ECPUs, M TB data + block storage for app tier +
+FastConnect to on-prem" — the typical "app on OCI Compute, DB on ADB-S" pattern.
+
+**SKUs:**
+
+| SKU | Component | Metric |
+|-----|-----------|--------|
+| `B95701` | ADB ECPU (ATP or ADW) — license-included | ECPU/hour |

+## Recipe 4 — Big Data Service + Data Science + Data Flow (analytics stack)
+
+**When it matches:** "HDFS-managed cluster for ETL", "notebooks + model deployment",
+"managed Spark pipelines" — typical OCI analytics/AI workload mix.
+
+**SKUs:**
+
+| SKU | Component | Metric |
+|-----|-----------|--------|

+| `EST-DF-SPARK` | **[Estimate]** Data Flow managed Spark runtime — priced as underlying VM.Standard OCPU | OCPU/hour |
+
+OCI Data Science and OCI Data Flow have no dedicated SKUs in the Oracle public
+pricing API — both are billed via the underlying Compute shape + Block/Object
+Storage consumed. The `EST-*` entries are placeholder estimates (VM.Standard3.Flex

+
+## When a recipe doesn't fit
+
+1. Grep the catalog: `grep -n "<product keyword>" kb/pricing/oci-sku-catalog.yaml`
+2. Check service docs under `kb/services/` for deployment-specific guidance.
+3. Check `kb/field-knowledge/` for known sizing/pricing gotchas.
+4. If a SKU still cannot be located, surface the gap to the user rather than guessing — fabricated SKUs break the BOM silently.

-    PharmaCorp Mexico operates 3 mission-critical Oracle databases (EBS R12, SAP, DW)
-    on aging Exadata X6 hardware. The hardware refresh quote is $1.8M and locks the
-    company into 5 more years of on-prem operations with no DR capability. Migration
-    to OCI ExaCS X11M reduces annual infrastructure costs by 61% ($1.75M over 3 years),

-  recommendation:
-    summary: >
-      Proceed with OCI ExaCS migration. 61% cost reduction over 3 years ($1.75M saved),
-      cross-region DR capability, and SOX compliance resolution. The alternative
-      (HW refresh at $1.8M) costs more and leaves DR + compliance gaps unresolved.

-# OCI Deal Accelerator — Proposal Spec
-# Demo: Pharma Mexico — ExaCS migration from on-prem Exadata X6
-# Prompt 1: Full proposal
-
-metadata:
-  customer: "PharmaCorp Mexico"
-  project: "Oracle Database Migration to OCI"
-  subtitle: "ExaCS Migration — Exadata X6 to OCI"
-  architect: "Carlos Mendoza"
-  firm: "Oracle Cloud Infrastructure"
-  date: "2026-04-12"
-
-summary:
-  why: >
-    PharmaCorp Mexico operates 3 Oracle databases (EBS R12, SAP, DW) on on-premises
-    Exadata X6 hardware approaching end-of-life. Hardware refresh costs $1.8M and
-    locks into 5 more years of on-prem operations. Migration to OCI ExaCS provides
-    30%+ cost reduction, eliminates hardware lifecycle management, improves DR posture
-    (RPO<15min, RTO<1h), and enables SOX compliance alignment with Oracle-managed
-    infrastructure patching.
-  current_state:
-    - "3 Oracle DBs on Exadata X6 (EBS R12 prod, SAP, Data Warehouse)"
-    - "200 concurrent users, peak during fiscal close"
-    - "2TB total data across all databases"
-    - "No DR — single site in Mexico City data center"
-    - "Manual patching quarterly — SOX audit finding pending"
-    - "HW refresh due in 6 months ($1.8M quote)"
-  target_state: >
-    OCI ExaCS X11M in Queretaro (prod) with Data Guard standby in Sao Paulo for
-    cross-region DR. Hub-spoke networking via DRG, dual FastConnect 10Gbps for
-    redundancy, WAF for web applications, OCI Vault for TDE key management.
-    SOX compliance via automated patching and audit logging.

-      rationale: "EBS is Platinum tier — needs cross-region DR"
-    - id: "D-06"
-      name: "Defense in Depth"
-      summary: "Multiple security layers, not single perimeter"

-    Dual-region ExaCS deployment: Queretaro (primary) + Sao Paulo (DR standby).
-    Hub-spoke networking with DRG provides segmented VCNs for each workload tier.

-    Key components:
-    - ExaCS X11M Quarter Rack in Queretaro (3 databases)
-    - Data Guard to ExaCS standby in Sao Paulo (EBS + SAP)
-    - Hub VCN with DRG for inter-spoke routing

-decisions:
-  - title: "ExaCS over ADB-S"
-    decision: "Use ExaCS instead of ADB-S for all 3 databases"
-    rationale: >
-      EBS R12 requires OS-level access for patches and customizations.
-      SAP on Oracle requires specific Oracle features not available on ADB-S.
-      DW benefits from ExaCS storage performance. All 3 share the same
-      Exadata infrastructure for cost efficiency.
-    alternatives: "ADB-S (rejected — EBS needs OS access), DBCS (rejected — no Exadata performance)"
-
-  - title: "Cross-Region DR with Data Guard"
-    decision: "Active Data Guard from Queretaro to Sao Paulo"
-    rationale: >
-      RPO<15min requires real-time redo shipping. Sao Paulo provides geographic
-      separation for disaster scenarios. Data Guard supports automatic failover
-      with FSDR for RTO<1h.
-    alternatives: "Backup/restore (rejected — RPO 24h), Same-region standby (no geo separation)"
-
-  - title: "Hub-Spoke Networking"
-    decision: "Hub VCN with DRG for inter-spoke routing and segmentation"
-    rationale: >
-      SOX requires network segmentation between environments. Hub-spoke with DRG
-      provides centralized security controls (WAF, NSG) while isolating workloads.
-    alternatives: "Flat VCN (rejected — no segmentation for SOX)"
-
-  - title: "Dual FastConnect"
-    decision: "Two 10Gbps FastConnect circuits from Mexico City"
-    rationale: >
-      Single FastConnect is a documented single point of failure. Dual circuits
-      provide redundancy for the EBS production workload.
-    alternatives: "Single FastConnect + IPSec VPN backup (acceptable for lower tiers)"
-
-  - title: "OCI Vault for TDE Keys"
-    decision: "External key management via OCI Vault instead of Oracle Wallet"
-    rationale: >
-      SOX requires separation of duties for encryption key management.
-      OCI Vault provides FIPS 140-2 Level 3 HSM-backed key storage.
-    alternatives: "Oracle Wallet on ExaCS (simpler but no separation of duties)"

+
+## 6. Spacing Rules
+
+### 6.1 Vertical Spacing
+| Measurement | Value |
+|-------------|-------|
+| Region label Y offset | 7px from region top |
+| VCN/Subnet label Y offset | 8px from container top |
+| VCN top to first subnet | 50px |
+| Subnet-to-subnet gap | 28px |
+| VCN-to-VCN gap | 26px |
+| Workload row gap | 23-27px (~25px) |
+| Gateway Y within VCN | 29px from VCN top |
+
+### 6.2 Horizontal Spacing
+| Measurement | Value |
+|-------------|-------|
+| VCN to subnet left indent | 42-44px |
+| Service icon X within subnet | 80px from subnet left |
+| Gateway X from VCN left | 168px |
+| AD-to-AD gap | 18-28px (~25px) |
+| Inter-region gap (Essbase) | 263px |
+
+### 6.3 Label Spacing
+| Measurement | Value |
+|-------------|-------|
+| Label box height | 20px (standard) |
+| Annotation box height | 17px |
+| Line-to-line spacing | 17px |
+
+---
+
+## 7. Connector Styles
+
+Oracle Visio-exported .drawio files do NOT use draw.io native edges. Connectors are thin rectangles:
+- Horizontal: Wx1 rectangles, stroke=#312d2a
+- Vertical: 2xH or 1xH rectangles
+- Cross-region (Essbase): stroke=#161513
+- Examples:
+  - Internet-to-Gateway: 350x1 at (80,153)
+  - Mid-connections: 156x1 at (98,524)
+  - DR replication: 549x1 at (391,1045)
+  - Vertical link: 1x65 at (1128,365)
+
+---
+
+## 8. Border/Stroke Styles
+
+| Element | strokeColor | strokeWidth | dashed | dashPattern |
+|---------|------------|-------------|--------|-------------|
+| Region | #9e9892 | 1 | No | - |
+| VCN | #aa643b | 2 | Yes | 4.00 2.00 |
+| Subnet | #aa643b | 2 | Yes | 4.00 2.00 |
+| AD | #9e9892 | 1 | No | - |
+| Solid grouping | #312d2a | 2 | No | - |
+| Connector | #312d2a/#161513 | 1 | No | - |
+
+---
+
+## 9. Double-Layer Container Rendering
+
+Oracle renders each container as TWO overlapping shapes:
+1. Fill layer: fillColor=<color>, strokeColor=none
+2. Stroke layer: fillColor=none, strokeColor=<color>
+
+This pattern applies to Region, VCN, Subnet, and AD containers.
+
+---
+
+## 10. Key Proportional Ratios
+
+| Ratio | Value | Description |
+|-------|-------|-------------|
+| Gateway:Service icon | 42:63 = 0.67 | Gateways 2/3 size of service icons |
+| VCN:Subnet width | 226:176 = 1.28 | VCN ~28% wider than subnet |
+| VCN left padding | 42-44px | Subnet indent |
+| VCN top padding | 50px | To first subnet |
+| VCN bottom padding | ~22-26px | After last subnet |
+| Region aspect (hub-spoke) | 456:845 = 0.54 | Portrait |
+| AD aspect (multi-AD) | 188:815 = 0.23 | Very tall/narrow |
+| Workload row aspect | 807:111 = 7.27 | Very wide/short |

+## 12. Layout Patterns
+
+### Single-Region Hub-Spoke
+- VCNs stacked vertically
+- External icons (Internet, On-Prem) at far left
+- Gateways between external and VCN
+- DRG centered with route table
+- Service icons right-aligned within subnets
+
+### Dual-Region DR
+- Regions side by side horizontally
+- On-Premises box centered above/between regions
+- ADs as vertical columns within each region
+- Workload tiers as horizontal rows crossing all ADs
+- Compartment boxes at AD-row intersections
+- DR arrows as horizontal lines between matching rows
