Codex Project Takeover Guide (superseded)

This in-repo document is superseded and no longer maintained. It was written 2026-08-11 at the conclusion of an early implementation slice (HANDOFF_SHA = 48a93862f95981c7c97b47ae94cc8467196b92c5, 2288 tests, Tier 1 execution-authorization work in progress). The project has moved substantially since then — v0.4.0/v0.4.1/v0.4.2 shipped, the first live WRITE capability was verified (ADR-026), an offline Nexus research track ran to completion (ADR-030–032), and ADR-033's privilege-derivation and provisioning-engine work landed — so nothing in the original body of this file (SHA, test counts, slice status) should be treated as current. It is intentionally not linked from this site's navigation.

The current, authoritative Codex handover lives outside this repository, in the project's external reports-ai/ directory (a local, Git-ignored symlink — see reports-ai/AI_CONTEXT.md's own "External AI handoff reports" note for why it is kept external):

  • reports-ai/CODEX_TAKEOVER.md — the full handover document.
  • reports-ai/CODEX_START_PROMPT.md — a short, copy-paste-ready starting prompt.
  • reports-ai/latest.md — current project status at a glance.
  • reports-ai/AI_CONTEXT.md — durable architecture/roadmap context.
  • reports-ai/NEXT_TASKS.md — the current outstanding-work queue.

If you are a fresh agent and do not have access to reports-ai/, ask the project owner for it before relying on anything below this notice — those files are the ones kept current after every phase, this one is not.

This page is left in place (rather than deleted) only because ADR-025 links to it as further reading, so the link keeps resolving — its retained presence here is a historical courtesy, not a claim that its original content remains architecturally relevant.
