description	Implement one phase of ./specs/91-impl-plan.md end-to-end, matching the specs and project quality bars, then review the diff and fix valid findings before declaring done. Use when the user asks to build a phase, milestone, next phase, or roadmap slice.

Impl

Use this Codex skill for phase-shaped implementation from specs/91-impl-plan.md. The canonical workflow is the Claude impl skill at .claude/skills/impl/SKILL.md; follow it, with the Codex-specific adjustments below.

Codex Adjustments

• Read AGENTS.md, CLAUDE.md, specs/91-impl-plan.md, cited specs, and relevant docs/research/ memos before editing.
• Use Codex's normal task tracking and local review. Use subagents only when the user explicitly asks for delegated or parallel agent work.
• Preserve user changes. Check git status --short before edits and avoid broad staging commands.
• Keep implementation scoped to the requested phase. Defer out-of-phase findings to specs/93-improvements-review.md.

Workflow

1. Bind the exact phase or milestone from specs/91-impl-plan.md.
2. Read every cited spec section and relevant research memo.
3. Identify exit criteria before writing code.
4. Implement tasks in dependency order.
5. Run local tests after meaningful changes and all standard gates before done.
6. Review the diff against the specs and CLAUDE.md; fix valid in-phase findings.
7. Report changed files, quality gates, residual risk, and the next unlocked phase.

Required Gates

cargo build --workspace --all-targets
cargo test --workspace --all-targets
cargo +nightly fmt -- --check
cargo clippy --workspace --all-targets -- -D warnings
RUSTDOCFLAGS="-D warnings" cargo doc --workspace --no-deps

For boundary modules and external-input paths, also run the stricter Clippy command from AGENTS.md. Run cargo deny check and cargo audit if dependencies change.

Quality Bar

No TODOs, placeholders, dead-code suppressions, unsafe, unwrap, or expect in production paths. Public surfaces need docs and tests. Spec adherence is binary: if implementation and spec disagree, stop and reconcile the mismatch in writing before continuing.
