1. governance_token authorizes repo operations 📘 Rule violation ⛨ Security
The workflow injects the org-admin GOVERNANCE_TOKEN directly into authenticated git URLs and gh commands for routine cross-repository clone, diff, push, and PR-creation operations instead of limiting it to org-level Project writes or membership checks. By bypassing the required ghcb or gh-app-token.sh identity path, the evaluation job unnecessarily exposes high-privilege credentials where short-lived, repository-scoped GitHub App tokens should be used.
Agent Prompt
## Issue description
The eval workflow uses the org-admin `GOVERNANCE_TOKEN` directly for routine cross-repository git and GitHub CLI operations instead of confining it to org-level Project writes or membership checks and using the repository-standard GitHub App token helper.
## Issue Context
Keep the governance token confined to its permitted CI uses. Acquire short-lived, least-privilege, repository-scoped GitHub App installation tokens through `ghcb` or `gh-app-token.sh`, scope each token to the appropriate target repository for CI-Workflows and archive operations, and avoid embedding `GOVERNANCE_TOKEN` in clone or push URLs or exporting it to `gh`.

2. Exit gate never enforced 🐞 Bug ≡ Correctness
T8 still marks an optimization card done after finding any merged PR that mentions the card; it never reads this registry or verifies a green eval-noninferiority ledger event. Therefore card #422 can close without this workflow running, or after it fails red, contradicting the new fail-closed exit-gate contract.
Agent Prompt
## Issue description
Optimization-wave exit gates are declared but never enforced by the card completion transition.
## Issue Context
T8 currently checks only for a merged PR. It must fail closed unless the configured wave has a bound green ledger event.

3. Candidate revision floats 🐞 Bug ≡ Correctness
The workflow evaluates whatever commit is at the default branch tip of CI-Workflows when dispatched, rather than the candidate introduced by optimization PR #132. Later runs can therefore evaluate unrelated rule changes while still recording the verdict as evidence for W5-OPT-1.
Agent Prompt
## Issue description
The candidate checkout floats with the remote default branch, so the verdict is not bound to the optimization under review.
## Issue Context
Resolve and pin the intended candidate commit, verify it belongs to the configured optimization PR, and evaluate that exact SHA.

4. Baseline missing from clone 🐞 Bug ☼ Reliability
git clone --depth 50 does not guarantee that the fixed pre-optimization commit remains in the shallow history, yet the next command dereferences it without fetching it. Once the baseline is more than 50 commits behind the branch tip, every dispatch fails before evaluation.
Agent Prompt
## Issue description
The depth-limited clone may not contain the policy-pinned baseline object required by `git show`.
## Issue Context
Fetch the exact baseline SHA before dereferencing it, or use a full clone, and verify the fetched object is a commit.

5. Wrong wave entry selected 🐞 Bug ≡ Correctness
Although the workflow declares WAVE=W5-OPT-1, both operational lookups read waves[0], while the assertion and ledger label independently hardcode W5-OPT-1. Reordering or prepending the registry makes the job evaluate another wave's baseline and PR diff but record the result under W5-OPT-1.
Agent Prompt
## Issue description
Operational configuration is selected by list position rather than the declared wave identifier.
## Issue Context
Resolve exactly one registry entry whose `id` equals `$WAVE`, fail on zero or duplicate matches, and use that same object for assertions, evaluation, contamination input, and evidence labeling.

6. Evidence omits decision inputs 🐞 Bug ◔ Observability
The workflow sets the provenance inputs_digest to only cand-report.json, excluding the baseline report, source commits, harness, policy, and corpus that jointly determine the verdict. The resulting ledger record cannot establish which comparison produced the claimed green result, and it also leaves subject.commit unset despite the evidence interface defining it as the judged object.
Agent Prompt
## Issue description
The evidence provenance hash covers only the candidate report rather than all inputs to the gate decision.
## Issue Context
Create a canonical manifest containing baseline and candidate report hashes, baseline and candidate commits, harness commit/path, corpus and diff hashes, policy hash, and optimization PR identity; hash that manifest and record the candidate commit in `subject.commit`.

固定候选版本和评测语料引用。
此 git clone 会使用 dispatch 时的 CIW 默认分支。后续步骤使用该工作区的 rules.yaml、harness 和 corpus，但污染检查只读取 PR #132 的 diff。
如果 CIW 在运行前继续合并，gate 可以对 PR #132 之外的内容生成 green evidence。baseline_quad 也没有绑定到实际使用的 corpus。
在 waves.yaml 中记录候选提交和评测语料的不可变引用或 digest。工作流必须 fetch 并 detached checkout 该候选提交，并在生成报告前验证 corpus digest。还应按 SHA 显式 fetch baseline_commit，避免依赖 --depth 50 的历史窗口。
