docs(kiro): head-to-head with kiro-lb from the landed tree - #6004
Conversation
Row-by-row comparison of the 35 inventory rows against merged dev (54ed02b) and kiro-lb bee73b3, each with its proving test. Every adopted row reaches parity or better; eight axes where kiro-lb still leads are listed with the reason, along with the behaviours verified only against fixtures.

There was a problem hiding this comment.
When a pool has multiple live accounts and only one reports the 1M GPT-5.6 limit, the observed catalog does not raise the effective window as stated. kiroObservedContextWindow marks the roster unknown if any live account lacks that model limit, adds the 272k static fallback, and returns the minimum, so it remains 272k until every live account reports a higher limit. Qualify this row accordingly so the C3 comparison does not overstate when parity is reached.

"채택한 20줄은 전부 동률 이상"인데 표의 C3와 E6는 일부만 동률이다. C3는 목록 증거가 있을 때 동률이고, 정적 272k는 kiro-lb가 앞선다. E6는 헤더 시간 초과를 504로 바꾸는 쪽만 동률이고, 연결 시간과 읽기 시간을 나누는 쪽은 아직 뒤다. 19줄은 목표 문장을 그대로 두면 못 맞춘다고 이미 적었다. 11줄을 그 범위에 맞춰라. 메인테이너의 판단이 필요한 지점

The projection test captured its clock before writing the exhaustion verdict, so a write in a later millisecond looked future-dated and the account read as not exhausted. It failed once in a batched dev CI run. The evaluation clock now follows every write.

- C3 uses a 272k static fallback when catalogue evidence is unavailable, versus kiro-lb’s 1M.

These qualifications support parity only for the adopted portions covered by the tests. The blanket statement can mislead readers about current full-axis capability.

The

Records the result of the second head-to-head with minpeter/kiro-lb, written from the merged tree after the seven Kiro layers landed (#5967, #5981, #5991, #5994, #5996, #6001, #6002).
devlog/_plan/260926_kiro_lb_parity2/081_head_to_head_result.mdcompares all 35 rows of the research inventory againstdevat54ed02be17and kiro-lb atbee73b3, each with the regression test that proves the opencodex side. Every adopted row reaches parity or better. Eight axes where kiro-lb still leads are listed with the reason we did not follow (IDE wire fingerprint, extra endpoint dialects, paid endpoint probe, MCP web search, per-model credit estimates, dashboard device-login UI, operations dashboard, connect/read timeout split), plus the static context-window fallback, and the behaviours verified only against fixtures rather than a live Kiro account.Docs only; no code change.

Summary by CodeRabbit
Also in this PR
test(kiro): evaluate auto-selection after setup— the 070 projection test captured its clock before writing the exhaustion verdict, so under load the verdict looked future-dated and the account read as not exhausted. It failed once in a manually dispatched dev CI run (run 36273574652, shard 2/4, batch 27); the evaluation clock now follows every write, and the test passed 8/8 when run in the same file batch locally.
