严重级别：主要。将 revoke payload 序列化为字符串。
第 169 行生成对象类型的 payload。governance/evidence_shadow.py 只接受字符串或 null，因此首个过期 grant 会在 append 时失败。sweep 随后不会执行 open-check，也不会写入 revoke 记录。
建议修复
- payload:{elevation_id:$g.elevation_id, capability:$g.capability, cause:"ttl-expired"}}' >event.json
+ payload:({elevation_id:$g.elevation_id, capability:$g.capability, cause:"ttl-expired"}|tojson)}' >event.json同时添加一个包含过期 grant 的 sweep 回归测试，并验证 revoke 追加后 open-check 成功。

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

1. Revoke events fail validation 🐞 Bug ≡ Correctness
The sweep writes payload as an object, but evidence_shadow.py append only accepts a string or null, so the first expired grant terminates the job before open-check, commit, or push. Expired grants therefore remain open and every later sweep fails on the same record.
Agent Prompt
## Issue description
Sweep-generated revoke events use an object-valued payload, which the shadow-ledger writer rejects.
## Issue Context
Adjudication events already serialize their payload; revoke events must use the same schema.

2. Concurrency drops elevation requests 🐞 Bug ☼ Reliability
cancel-in-progress: false protects the running workflow but GitHub still retains only one pending run by default, replacing an older pending /elevate run when another arrives. A burst of comments can therefore be canceled before adjudication, leaving no ledger record or reply for the discarded request.
Agent Prompt
## Issue description
The workflow-level concurrency group can replace pending issue-comment runs, silently dropping elevation requests.
## Issue Context
Each comment is a separate workflow run, while serialization is required for the append-only ledger. Configure the supported multi-run queue if available, or durably enqueue comments and let one writer drain them; ensure overflow cannot silently lose requests.

3. Retry omits adjudication reply 🐞 Bug ☼ Reliability
If the ledger push succeeds but gh issue comment fails, rerunning or redelivering the event hits the ledger idempotency check and exits before posting the missing reply. The request is recorded but the requester never receives the promised grant/deny result, and the retry reports success without repairing it.
Agent Prompt
## Issue description
The ledger-only idempotency shortcut prevents retries from restoring an adjudication reply that previously failed.
## Issue Context
Persist or detect reply completion separately from ledger completion, and on an existing delivery reconstruct/repost the result when its reply is absent.

4. Large ledger silently disappears 🐞 Bug ≡ Correctness
The new elevation source uses the default JSON Contents API response and decodes content; once the append-only ledger exceeds 1 MB, GitHub returns an empty content field with encoding: none, which this code accepts as a successful empty file. Queries then return zero elevation records with exit 0, violating the unified evidence query’s fail-closed behavior.
Agent Prompt
## Issue description
The elevation ledger becomes a silently empty query source after it grows beyond the Contents API's 1 MB JSON-content limit.
## Issue Context
Request the raw media type or detect unsupported encoding/size and fetch through an appropriate endpoint; decoding failures and unexpected empty responses must fail closed.
