Follow-up to agentflare item #751 (NOT GitHub PR #751), from a review against docs/audits/2026-10-18-harness2-integration.md.

Changes

• A timed-out acceptance check now yields accepted = None (unknown) instead of Some(false). The audit requires that a failed evaluator never becomes a zero score; previously a slow or flaky check could eliminate a good candidate or make the baseline look bad. Logic is in check_verdict, covered by timed_out_check_is_unknown_not_failed.
• Session telemetry attached to receipt evidence is capped at 64K chars (tail kept, truncation noted), so long sessions no longer fan out into hundreds of evidence files for the proposer.

Verification

• cargo test --bin agentflare refinement:: : 27 passed (plain cargo, as in the branch ledger; mbx not used)
• cargo fmt --check clean
• Not run: full workspace, Linux

Not addressed (follow-ups)

• harness-experience observations are written directly via observations::save, bypassing the evidence-gated memory action=promote path from fix: Fix pending_corrections' redispatch-boundary gap: persist the comment cursor on the item, not the ephemeral run #757. Worth rerouting once chore: agent-browser auto-install resolves a dead mise shim instead of the mise-managed binary #751 merges.
• The Unix symlink staging test (staging_rejects_linked_skill_ancestor) has never executed on Linux; confirm CI covers it before merging.

Summary by CodeRabbit

• Bug Fixes
  • Timed-out acceptance checks are now reported as unknown rather than failed. Successful and non-timeout failed checks retain their results, and processing stops at the first check that does not succeed.
• Improvements
  • Solver session telemetry is limited to the most recent 64 KiB of text. When earlier content is omitted, the telemetry includes a notice that it was truncated.

📝 Walkthrough

Acceptance-check processing now treats timed-out checks as unknown and stops at the first non-success verdict. Session telemetry now includes at most the final 64 KiB of characters, with a truncation notice when needed.

Changes: Refinement backend updates

Layer / File(s)	Summary
Acceptance-check verdicts src/refinement/backend.rs, src/refinement/tests.rs	check_verdict returns None for timed-out checks and Some(success) otherwise. Processing stops at the first non-success verdict. Tests cover successful, failed, and timed-out checks.
Session telemetry cap src/refinement/backend.rs	Session telemetry includes only the final 64 KiB of characters. Evidence includes a truncation notice when the original text exceeds the cap.

The description explains the purpose, implementation, verification results, known test limitations, risks, and follow-up items. It uses equivalent sections instead of the exact template headings and does not report a clippy run, but it is mostly complete.
