From 2631766ff7d95f10d1cafa2615782b62cdfe44e8 Mon Sep 17 00:00:00 2001 From: Parfii-bot Date: Wed, 13 May 2026 22:44:00 +0800 Subject: [PATCH] fix(kei-model-router): close 2 HIGH regressions from re-audit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Re-audit (codex + critic-bug) on commit 3b03fb7b confirmed all 10 original findings closed, but flagged 2 HIGH regressions the fix itself introduced. NEW-1 fix — non-Claude profile no longer falls back to Opus - main.rs::build_select_input: when Model::from_slug returns None (any non-Anthropic provider — codex/xai/deepseek/google/local), cmd_select bypasses posterior+kernel entirely and prints (provider, model_id) directly with reason="profile_default_non_claude". - Posterior machinery stays Claude-only by design — RULE 0.20 escalation ladder operates on Anthropic family. Cross-provider routing is registry-driven, not enum-driven. - Test non_claude_profile_triggers_provider_bypass: pick("codex-reviewer") = ("codex","gpt-5-codex"); Model::from_slug("gpt-5-codex") = None — assertion locks behaviour. NEW-2 fix — no-ledger path preserves profile-resolved fallback - print_decision_no_ledger signature changed from (dna, prompt) to (input: &DecisionInput, dna). Uses input.fallback.slug() so the Sonnet/Haiku selected by profile resolution survives instead of being overwritten with constructor-default Opus. - Test decision_input_preserves_set_fallback verifies the round-trip. Verification (orchestrator-side): - cargo check → clean - cargo test --release → 65 passed / 0 failed (was 63 → +2 regression tests) - Constructor Pattern → all files ≤ 200 LOC (main.rs 197 at limit) DNA-INDEX.md regenerated by kei-registry hook (cosmetic). === STATUS-TRUTH MARKER === shipped: functional stubs: 0 cargo-check: PASS behaviour-verified: yes follow-up-required: - CLI stdout for non-Claude profiles gains a "reason: profile_default_non_claude" line; downstream parsers must handle the new variant. --- .../_rust/kei-model-router/src/main.rs | 76 ++++++++++++------- .../_rust/kei-model-router/src/select.rs | 33 ++++++++ docs/DNA-INDEX.md | 2 +- 3 files changed, 81 insertions(+), 30 deletions(-) diff --git a/_primitives/_rust/kei-model-router/src/main.rs b/_primitives/_rust/kei-model-router/src/main.rs index efa112c..78ee7ef 100644 --- a/_primitives/_rust/kei-model-router/src/main.rs +++ b/_primitives/_rust/kei-model-router/src/main.rs @@ -1,11 +1,5 @@ -//! kei-model-router CLI. -//! -//!
