GPT Review — G6 Codex Executor Readiness

Date: 2026-04-27
Scope: Final review before user authorizes G6 execution, including whether Codex may be used instead of Claude CLI/Claude Code.

Verdict

PASS. G6 may be executed by Codex if Codex has the required VPS/DB shell access and can follow the OFFICIAL v0.2 prompt without scope expansion.

The prompt text currently names Claude CLI / Claude Code as executor, but the governance requirement is capability and controlled execution path, not the brand of the coding agent. Codex is acceptable if Opus remains the orchestrator and Codex is given an executor-adapter instruction stating it is replacing the named Claude CLI role.

Law / constitutional check

Rule	Result	Finding
Hiến pháp / Zero Trust	PASS	Executor substitution is acceptable only if Codex follows the same source-of-truth prompt and fail-stop rules.
Đ33 DB governance	PASS	Isolated schema only; no production business schema mutation.
Đ35 DOT governance	PASS	No dot_tools/dot_action_log mutation.
Đ32 gate discipline	PASS	User authorization still required before execution.
Đ24	PASS	No taxonomy/entity label mutation.

Conditions for Codex execution

1. Codex must read and follow P9-G6-execution-prompt.md OFFICIAL v0.2.
2. Codex is executor only; Opus remains orchestrator.
3. Codex must not reinterpret scope or skip pre-flight.
4. If any pre-flight fails, Codex must STOP and report.
5. If p9_g6_dryrun already exists, Codex must STOP and must not auto-DROP.
6. Codex must compute SHA-256 for seed files during execution and record raw output in the action log.
7. Codex must upload the action log and stop; no G8/G11/P9 continuation.

Effort recommendation

Use high effort / maximum reasoning for Codex. This task involves production DB instance access, DDL/DML in isolated schema, rollback verification, and strict governance constraints. Lower effort risks skipping pre-flight or mishandling expected-error tests.
