Tracks #266 and #267; it does not close them until the complete matched evaluation passes.

Root cause: an earlier live run used the repository checkout worker instead of the exact candidate worker, and its ledger cap did not match the then-approved US$10 limit. The partial reports cannot support a V2/V3 comparison.

Approach: run the frozen 30-fixture × 3-repeat cohort against immutable V2 v2.0.8 and one final V3 candidate. Both arms use the candidate worker, identical Responses request normalization, isolated workspaces, independent effect verification, and a worst-case reservation before every provider request. Unknown usage remains held.

Budget: the approved cumulative Panstar cap is now US$20. Prior exposure is conservatively carried as a US$10.20 hold, leaving at most US$9.80 for all new requests. The runner rejects higher limits and stops when reservations cannot fit.

Validation: 44 focused benchmark tests pass; the full suite passes (1,093 tests, 2 skipped). make check, make lint, make docs-check, wheel smoke, agent/sub-agent acceptance, and TUI acceptance pass. Commit 985f725 is GPG-signed and verified; CI for this head is running.

Evaluation status: earlier partial campaigns used about US$10.20 of cumulative exposure, including held unknown usage. They remain incomplete and inconclusive, with no quality or statistical gate claimed. A fresh run is required after the final candidate SHA is set; its pre-call reservations remain within the new US$20 cap.

Risks and follow-up: #266/#267 remain open. This PR stays in draft until the matched cohort has complete usage and passes every safety, outcome, cost, latency, and regression gate.

📝 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 · up to 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.

Review comments at @benchmarks/v3_matched.py:
- Around line 280-282: Convert `token_savings` to a JSON-serializable float when
populating `token_savings_fraction` in `summarize()`, preserving `None` when the
value is unavailable. Leave the other comparison fields unchanged.
