Scoring, pass/fail judgment, evaluator execution, approval claims, automatic discovery, overwrite behavior, and existing-bundle integrity validation remain out of scope and external scoring remains authoritative. - Implemented CR-126 (Preflight Privacy Before Ledger Persistence): Moved `tc run` packet verification ahead of ledger construction and task-event creation, so privacy-blocked input exits before a ledger event is written. Successful runs now persist fixed content-withheld task metadata plus prompt/data lengths rather than raw input. Extended the persistent-artifact invariant and its audit command to reject forbidden raw-content keys and high-confidence PII, credential, and precise-location value patterns without echoing detected values. Historical records are not rewritten, and arbitrary free-text classification remains out of scope. - Implemented CR-125 (Honor Terminal Resilience Routes): Made `human_handoff` and the currently unimplemented `deterministic` route terminal at the governed `TriageClient.run_task` boundary. Each now records the route decision plus a `worker_result` with `worker_result_status=not_attempted`, returns `handoff_required`, and reaches the existing `tc run` exit-3 contract without invoking a local or cloud backend. This slice does not add approval-and-resume behavior, change the broader `human_review_required` semantics, or alter cloud gating, signatures, reducer behavior, or other execution surfaces. - Implemented CR-124 (Eval Handoff Hygiene, Bug, and Drift Slice): Fixed `write_actual_outcomes()` so generator and other single-pass iterable inputs still write all actual outcome files after duplicate checks, updated stale eval fixture/taxonomy sequencing docs so they no longer imply internal TriageCore scoring, and added focused regression/drift coverage. No evaluator execution, scoring, score interpretation, model/backend calls, routing/admission integration, ledger writes, schema changes, bundle builder, or result import/display were added. diff --git a/docs/change/requests/CR-127-evaluation-handoff-bundle-builder.md b/docs/change/requests/CR-127-evaluation-handoff-bundle-builder.md new file mode 100644 index 0000000..ab33236 --- /dev/null +++ b/docs/change/requests/CR-127-evaluation-handoff-bundle-builder.md @@ -0,0 +1,41 @@ +# CR-127 — Evaluation Handoff Bundle Builder + +## Status + +Implemented + +## Purpose + +Add a deterministic file-only builder that packages an explicit validated +fixture and explicit actual-outcome directory for an external evaluator while +preserving the CR-123 boundary that TriageCore does not score or interpret +evaluation results. + +## Scope + +- Add `triage_core/evaluation_handoff_bundle.py`. +- Add `tc eval build-handoff --fixture --actuals-dir --out-dir `. +- Emit the fixed fixture, actuals, and manifest layout documented by + `evaluation_handoff_manifest.v0`. +- Copy source evidence byte-for-byte and record deterministic SHA-256 hashes. +- Validate all inputs before staging, enforce persistent privacy invariants, + and publish with a sibling atomic rename. +- Add focused pure-module and CLI coverage. + +## Non-Goals + +- No scoring, pass/fail judgment, score interpretation, or approval claim. +- No evaluator, model, backend, endpoint, or network invocation. +- No automatic file discovery, defaults, overwrite, or `--force`. +- No routing, admission, ledger, approval, or worker integration. +- No new fixture, decision, or boundary-family vocabulary. +- No validation of an already-created bundle; integrity validation is a + separate future CR. + +## Validation + +- Focused: + `python -m pytest -q tests/test_evaluation_handoff_bundle.py tests/test_evaluation_handoff_bundle_cli.py tests/test_eval_handoff_contract.py tests/test_eval_outcome_contract.py tests/test_eval_fixture_validator.py tests/test_eval_fixture_cli.py` + -> 60 passed +- Full suite: `python -m pytest -q` -> 971 passed, 2 skipped +- `git diff --check` diff --git a/docs/current_backlog.md b/docs/current_backlog.md index 966d2d9..290052f 100644 --- a/docs/current_backlog.md +++ b/docs/current_backlog.md @@ -2,10 +2,14 @@ ## Status -This document summarizes the active TriageCore backlog after CR-126. +This document summarizes the active TriageCore backlog after CR-127. ## Active GitHub Backlog +- CR-127: Evaluation Handoff Bundle Builder + - Status: complete via CR-127 + - Purpose: Package an explicit validated fixture and explicit actual-outcome directory into a deterministic, privacy-checked, unscored handoff bundle with byte-preserving copies and a SHA-256 manifest.
