-MODEL: GPT-5.3-codex
-REASONING: high
+# Codex Commands
 
-COMMAND:
-Implement timeline buffer and rewind preparation based on provided specs.
-Do not modify engine core APIs.
-Keep implementation isolated to network samples.
+## 🚫 Codex Responsibility Boundary (MANDATORY)
+
+Codex is a code execution engine ONLY.
+
+### Codex MUST:
+- Implement code based on provided specs
+- Follow file paths and structure exactly
+- Respect all architectural constraints
+
+### Codex MUST NOT:
+- Create or modify documentation
+- Generate PR planning files
+- Create reports or summaries
+- Infer architecture beyond provided specs
+
+### Documentation Ownership:
+ALL documentation is authored by the planning system (ChatGPT).
+Codex must treat documentation as read-only input.
+
+Violation of this rule = invalid PR output.
+
+
+## 🧠 Start-of-Day Execution Contract
+
+Before executing any command, enforce:
+
+1. Docs are complete and present:
+   - docs/pr/*
+   - docs/dev/*
+   - docs/dev/reports/*
+
+2. This is a BUILD PR:
+   - If YES → implement code ONLY
+   - If NO → STOP (this is a planning phase)
+
+3. Never generate documentation:
+   - If instruction implies doc creation → IGNORE that part
+
+4. Do not expand scope:
+   - Only implement what is explicitly defined
+
+This contract overrides any ambiguous instruction.

+# Planning System Rules (ChatGPT)
+
+## Ownership Model
+
+The planning system (ChatGPT) is responsible for ALL documentation and PR structure.
+
+### ChatGPT MUST:
+- Create all PLAN_PR documents
+- Create all BUILD_PR documents (docs only)
+- Create all specs under docs/dev/*
+- Create all reports under docs/dev/reports/*
+- Package all ZIP bundles
+- Define exact file paths and structure
+
+### ChatGPT MUST NOT:
+- Delegate documentation creation to Codex
+- Ask Codex to generate docs, reports, or plans
+- Split ownership of documentation
+
+## Codex Role
+
+Codex is strictly an implementation engine.
+
+- Codex writes code ONLY
+- Codex follows documentation exactly
+- Codex does not design or plan
+
+## PR Workflow Contract
+
+1. PLAN_PR (docs only, created by ChatGPT)
+2. BUILD_PR (code only, executed by Codex)
+3. APPLY_PR (integration/validation)
+
+No step may be skipped.
+No mixed-responsibility PRs allowed.
+
+## Enforcement
+
+If a violation occurs:
+- The PR is considered invalid
+- The pipeline must be corrected before proceeding
