Tracks #266 and #267; this PR closes them only after a complete, passing matched evaluation.

Root cause and approach

The harness rejected its own interrupted-run checkpoint because resume validation looked for the prior budget hold at the report's top level, while the report stores it under budget. A transport interruption therefore prevented safe campaign resumption.

The runner uses a frozen 30-fixture × 3-repeat cohort against immutable V2 v2.0.8 and one exact V3 candidate. Both arms use the same worker, normalized Responses requests, isolated workspaces, and independent effect verification. It reserves worst-case cost before every provider request, requires the prior budget hold, preserves unknown usage as reserved, and reports provider usage from the relay journal. Replanning scenarios include typed update_plan behavior behind its capability and Strategic Plan guards.

Validation

The exact-model regression first failed because the relay sent gemini-3.5-flash-lite, then passed with the approved gemini-3.1-flash-lite pin. Focused benchmark tests passed (63, one sandbox-dependent skip) on earlier head 8f4ba7b2c30c67d5e658657162d3fe9b10a5f435.

Full OpenKyrozen CI passed on that earlier exact head in run 40529864256: full Python and core suites, agent workflow acceptance, syntax/inventory/provider/documentation checks, wheel install and rebuilt TUI acceptance, Docker persistence, installer syntax, and installed-update checks on Linux, macOS, and Windows. Two path-filtered jobs were skipped. The separate site build passed in run 40529864506.

Latest follow-up

Commit 54d17229fb3b101aac75cddb173f62b5d9c2444d fixes a review finding in the Strategic Plan benchmark fixtures. They advertised shell/process authority although the Strategic Plan guard intentionally rejects process effects. The scope-preserving prompt now leaves test execution to the independent evaluator, and both affected plans omit shell/process bounds; the guard remains unchanged.

The branch was then updated to current main via signed merge commit 08d2b06f58849857bf28469b8b301137a5b51a4d (parent 85cbb9f8d37a5d4bdcc0ce664bea2f5a898e9388). It resolves the overlap in tests/test_interaction.py by retaining both the active-plan preservation and stale queued-acceptance regressions. GitHub now reports the PR mergeable against current main.

• The fixture-bound regression failed on the prior bounds and passed after the change.
• make PYTHON=python3.14 lint and git diff --check pass.
• Diagnostic focused benchmark run on Python 3.14 ran 49 tests: two skipped and one V2 worker test failed because rich is unavailable.
• The supported Python 3.12 test module could not import because requests is unavailable locally.
• Fresh checks completed for exact head 08d2b06f58849857bf28469b8b301137a5b51a4d in CI run 40860366925: core-test (Python 3.12 non-browser suite and docs checks), python-test (Python 3.13 full suite and workflow acceptance), wheel install/TUI acceptance, Docker persistence, installer syntax, and Linux/macOS/Windows installed-update jobs passed. full-python-312 and direct tui-test were skipped by the configured selector, so a full Python 3.12 suite and standalone Go TUI test are not evidenced by this run. The associated site build passed; deploy was skipped.

Benchmark and budget

Live model calls are paused as requested. The reported 3.5 attempt stopped at 133/180 rows with incomplete usage; the correctly configured 3.1 attempt stopped after one request with unknown usage. The mislabeled report that sent requests to 3.5 is excluded as 3.1 evidence. The source reports and SQLite budget ledger are unavailable here, so cumulative exposure under the approved US$20 cap cannot be verified. Unknown usage remains reserved. No complete matched result or spend claim is recorded.

Remaining work

#266 and #267 remain open: the matched cohort, reconciled usage, and statistical outcome/efficiency gates have not passed. Keep this PR draft until that evidence is complete. No live calls, PR merge, or public release are authorized by this update.

Walkthrough

This pull request adds a matched V2/V3 evaluation harness with a fixed fixture cohort, worker measurements, budget accounting, a Responses relay, and resumable reporting. It also changes executing-plan task preservation and synchronizes CLI spinner display across concurrent calls.

Changes: V3 matched evaluation

Layer / File(s)	Summary
Fixture catalog and validation benchmarks/v3_fixtures.py, tests/test_v3_fixtures.py	Defines 30 fixtures across ten categories, adds plan-task seeds and verifiers, and validates cohort size, category counts, and required plan scenarios.
Worker configuration and measurements benchmarks/prompt_worker.py	Selects the provider and model, accepts optional plan input, and records runtime events, receipts, process activity, plan state, and timing in the result.
Pricing, budget ledger, and matched summaries benchmarks/v3_matched.py, tests/test_v3_matched_benchmark.py	Adds RMB pricing, persistent budget reservations and settlements, and paired-result summaries with completeness and comparison checks.
Authenticated Responses relay benchmarks/v3_responses_relay.py, tests/test_v3_responses_relay.py, tests/test_delegation.py	Adds authenticated request forwarding, budget reservation and settlement, stream handling, and upstream-error fail-stop behavior. The tests also cover provider access through the relay and accepted Anthropic credential headers.
Matched execution, verification, and reporting benchmarks/v3_matched_live.py, tests/test_v3_matched_live.py, docs/index.md, docs/v3-evaluation.md	Runs both arms in isolated workspaces, verifies fixture outcomes, checkpoints and reconciles reports, and documents the cohort and run requirements.

Executing plan resumption

Layer / File(s)	Summary
Preserve executing plan tasks openkyrozen/agent/loop.py, tests/test_interaction.py	When an executing plan has no mode override, the chat turn does not clear its tasks. A test checks that task IDs remain unchanged.

Spinner synchronization

Layer / File(s)	Summary
Synchronize concurrent spinner display openkyrozen/app/state.py, openkyrozen/interfaces/cli/rendering.py, tests/test_delegation.py	Uses a shared nonblocking lock to guard spinner display and tests concurrent LLM calls.

Possibly related issues

• Issue 267: The V3 evaluation adds replanning, task-change, scope-preservation, material-revision, and plan-churn scenarios that exercise the evaluation objectives described in the issue. The live evaluation remains unverified.

Merge Risk: Moderate · previous review f8268

Two defects in the live evaluation runner can waste the ¥49 budget. A complete matched run would crash while writing its final report, and a host without a working OS sandbox would spend budget on rows that all fail verification. Fix both before running the live evaluation.

_credential(), and stop the campaign with a clear error when no backend is
usable; close any probe invocation. Guard the direct sandbox-dependent unit test
so it does not fail when no backend is available, while preserving
_run_fixture_tests behavior.
