Some checks failed
lakehouse/auditor 14 blocking issues: cloud: claim not backed — "Verified end-to-end:"
The post-fix audit on commit 454da15 produced a fresh BLOCK and
re-flagged the dead tree-split as still dead. This commit lands the
BLOCK fix and the deletion.
LANDED:
1. kimi_architect.ts:113 BLOCK — MAX_TOKENS=128_000 exceeds Anthropic
Opus 4.x's 32K output cap. Worked silently (Anthropic clamps
server-side) but was technically invalid. Replaced single-default
with `maxTokensFor(model)` returning per-model caps:
claude-opus-* -> 32_000 (Opus extended-output)
claude-haiku-* -> 8_192 (Haiku/Sonnet default)
claude-sonnet-* -> 8_192
kimi-* -> 128_000 (reasoning_content needs headroom)
gpt-5*/o-series -> 32_000
default -> 16_000 (conservative)
LH_AUDITOR_KIMI_MAX_TOKENS env override still works (forces value
regardless of model).
2. inference.ts dead-code removal — Opus flagged tree-split as still
dead post-2026-04-27 mode-runner rebuild. Removed 156 lines:
runCloudInference (lines 464-503) legacy /v1/chat caller
treeSplitDiff (lines 547-619) shard-and-summarize fn
callCloud (lines 621-651) helper for treeSplitDiff
SHARD_MODEL const qwen3-coder:480b
SHARD_CONCURRENCY const 6
DIFF_SHARD_SIZE const 4500
CURATION_THRESHOLD const 30000
No live callers — verified by grep before deletion. The mode
runner's matrix retrieval against lakehouse_answers_v1 supplies
the cross-PR context that tree-split was synthesizing from scratch.
3. inference.ts:38-49 stale comment about "curate via tree-split"
replaced with current "matrix retrieval supplies cross-PR context"
semantics. Block was already physically gone but the comment
describing it remained, contradicting the actual code path.
SKIPPED (defensible / minor):
- WARN: outage sentinel TTL refresh on continued failure — intentional
(refresh keeps cache valid while upstream is still down)
- WARN: enrichment counts use Math.max — defensible (consensus
enrichment IS the max of the three runs)
- WARN: parseFindings regex eats severity into rationale on multi-
paragraph inputs — minor, hasn't affected grounding rate
- WARN: selectModel uses pre-truncation diff.length — defensible
(promotion is "is this audit worth Opus", not "what does the model
see")
- INFO×3: static.ts state reset, parentStruct walk bound,
appendMetrics 0-finding rows — all defensible per current intent
Verification:
bun build auditor/checks/{inference,kimi_architect}.ts compiles
systemctl restart lakehouse-auditor.service active
Net: -184 lines, +29 lines (155 net deletion).
