From 187661714fd5e0185ca6818d3ee8ab306a30e399 Mon Sep 17 00:00:00 2001 From: Parfii-bot Date: Wed, 13 May 2026 22:09:19 +0800 Subject: [PATCH] fix(kei-model-router): close 10 audit-blocker findings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Codex CRITICAL + 4 HIGH + 5 MEDIUM/LOW from RULE 0.23 dual-review and RULE 0.25 multi-critic swarm — all closed. CRITICAL fix - Model::slug() ledger compatibility: posterior.rs + select_kernel.rs query `WHERE model = ?2 OR model = ?3`, binding canonical + legacy slug pair via new `Model::legacy_slug()`. Production ledger rows written under "haiku"/"sonnet"/"opus" remain visible to posterior aggregation. Regression test ledger_legacy_slug_counted. HIGH fixes - cmd_select(): no longer early-returns on profile match. Profile's default_model_ref now becomes DecisionInput.fallback; select() always runs, posterior/kernel evidence wins if present. RULE 0.20 cost optimisation restored for all 18 registered agents. - Registry pricing SSoT: DecisionInput now carries Option>. estimated_cost() tries registry first; hardcoded match is documented fallback only. select_posterior.rs no longer duplicates models.toml constants. - registry.rs portability: include_str!() embeds the three TOMLs at compile time. load_embedded() new; disk path tried first via KEI_REGISTRIES_DIR, embedded as fallback. `cargo install`d binaries now find registries unconditionally. embedded_registry_matches_disk test ensures embedded ≡ disk source. - next_model() ambiguity: replaced Option<&Model> with EscalationResult enum (Next(&Model) / AtTop / NotFound). Callers can distinguish typo from ceiling. 5 new tests. MEDIUM fixes - posterior.rs u32 overflow: `(n_plus + n_minus) as u32` → `u32::try_from(n_plus.saturating_add(n_minus)).unwrap_or(u32::MAX)`. overflow_guard_on_huge_n test with i64::MAX. - pick() unknown-model: now returns None when default_model_ref's model is absent from registry. Inverted the deprecation guard. - HOME unset: disk_registries_dir() returns None on empty HOME and falls through to embedded registries. open_ledger() logs warning and returns None instead of opening at malformed path. - SQLite WAL + busy_timeout: applied to ledger connection in open_ledger() — concurrent CLI invocations no longer SQLITE_BUSY. LOW fixes - impl Model consolidation: next_tier() moved to pricing.rs. escalate.rs uses current.next_tier() instead of duplicating logic. - complexity.rs: removed duplicate "ml-implementer" in HEAVY_ROLES. - dna_class.rs: role("") now returns None instead of Some("").
