feat(email-writing): add independent criterion Judge - #1402
Conversation
Add failing Task 7 fixtures and focused tests for criterion subsets, untrusted Judge tasks, strict JSON validation, same-model fail-closed policy, withheld admission, and released-package absence. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>
Add the naruon-owned Task 7 Judge contract: required criterion subsets, untrusted task construction, strict Judge JSON parsing, withheld admission, and fail-closed import of a released fast-mlsirm package. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>
Cover remaining Judge contract branches for empty replacements, non-canonical anchors, injected package importers, and matrix export. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>
Add a contents:read Judge workflow with persist-credentials disabled. Do not restore write-capable promotion or finalize workflows. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>

📝 WalkthroughWalkthroughChangesThe PR adds an independent email-writing Judge service. It defines strict contracts, fail-closed package loading, bounded untrusted payloads, output validation, privacy-preserving hashes, response-matrix export, comprehensive tests, and a dedicated CI workflow. Email Writing Judge
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This PR adds the Judge contract and evaluation plumbing, but the current implementation can skip required checks, misclassify empty replacements, expose runner failure details, corrupt evaluation-column alignment, and let candidate confidence influence judging. It is not merge-ready until these bounded correctness, validation, and data-handling issues are fixed. Sequence Diagram(s)sequenceDiagram

In @.github/workflows/email-writing-judge-tdd.yml:
- Around line 8-13: Add backend/requirements-hashes.txt to the pull_request
paths list in the workflow so changes to the installed dependency lock trigger
all Judge tests, coverage, lint, and compilation checks.
In `@backend/services/email_writing_judge.py`:
- Around line 476-487: Update evaluate around self._runner.judge to enforce a
bounded call deadline and catch all runner failures, including provider,
transport, and JudgeFormatError exceptions. Convert them into the established
EmailWritingJudgeError with a deterministic, payload-redacted error_code,
preserving the exception only for internal logging if supported without exposing
its message.
- Around line 490-502: Update judge_results_to_response_rows to use
EMAIL_WRITING_JUDGE_CRITERION_IDS as the single fixed column order for every
evaluation, rather than sorting each evaluation’s keys independently. Validate
that each evaluation’s criterion set exactly matches the expected set and raise
EmailWritingJudgeError for mismatches before constructing rows; preserve the
existing empty-input error.
- Around line 309-329: The build_email_writing_judge_task flow currently
forwards the full diagnostic, including candidate_confidence, to both the
candidate payload and answer_text. Add an explicit allowlist projection
containing all Judge-evaluable fields, including priority, and use that
projected payload for request_payload["candidate"] and _canonical_json; add a
regression assertion confirming candidate_confidence is absent from both
outputs.

Description
This Draft PR implements Task 7 of the accepted LLM email-writing guidance plan: the naruon-owned independent criterion Judge contract. It is stacked on live #1375 (
feat/llm-email-writing-candidate-task6@fa844bd035ab1f188a28c58e0ed2dc45fa31d0f3).This revision addresses the CodeRabbit

This PR is Judge-contract only. Customers should continue to write and send email with the current editor and send path. No user-facing writing-guidance diagnostics, language profile, or model is available in product. Writing and sending stay on the current path. This slice is not shipped.

Blocker carried forward
Task 7 cannot call the released Judge until fast-mlsirm publishes an immutable hashed package containing
ContextualOrchestratorJudgeand the IRT matrix validator (Task 1). Task 8's published calibration policy is also absent. This slice therefore implements only the naruon-owned contract and fails closed.Local validation
