Roadmap item 6: Add inactive Codex CLI producer normalizer payload

[yihanzhu]

Summary

• Roadmap item 6, first alternative harness. adapters/codex-cli-producer/v1/normalize.jq is the Claude Code producer normalizer with only the harness identity swapped: snapshot kind and content id, manifest id, recorded snapshot fact, adapter id, and the model provider the binding must name (openai). Every trust relation, snapshot relation, state, reason, and the generic observation are the same, so a profile can select either harness under one core contract.
• The test proves it: the Claude program with those six tokens substituted is byte-identical to this one; the full producer contract suite passes against the new identity; a snapshot, recorded fact, or provider from the other harness is refused.
• Payload only, no manifest. Branches from main; not stacked.

Inactive boundary

No Codex or model call, credential, network, target write, publish, or profile activation. Pure jq over the core modules.

Exact candidate

• Head: 7d4a0e4
• Base: main at a637451
• Roadmap: item 6, Alternative adapters, unit 2 (alternative harness payload; eval wiring for both alternatives follows once Roadmap item 6: Add inactive GitLab forge normalizer payload #239 and this land)
• Owned paths (4): adapters/codex-cli-producer/v1/normalize.jq (new), scripts/test/default-codex-cli-producer-adapter.test.sh (new), README.md, ci/required-files.txt

Current-head local proof

• bash scripts/test/default-codex-cli-producer-adapter.test.sh — 46/46 checks passed
• ShellCheck 0.11.0 — clean
• Schema activation guard and rename gate — clean on the committed tree

Fresh CI and a fresh independent review are required for this head.

The new inactive Codex CLI producer normalizer mirrors the existing Claude producer contract with the intended identity substitutions, is covered by a focused test, and is included in the required-files manifest. I did not find a discrete correctness issue introduced by this patch.

The added Codex CLI producer normalizer mirrors the existing Claude Code producer contract with the intended identity substitutions, and the new test covers the adapter states, provenance, stale/malformed inputs, and cross-harness rejection. I did not identify a discrete correctness issue in the changed files.
