From 5c1a88d9f7be8ab354f61898d21b86aa757ec092 Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Tue, 4 Aug 2026 12:44:08 +0300 Subject: [PATCH 1/2] fix(kernel): guard the three unenforced DomainGroup consumers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `DomainGroup` has three consumers the compiler does not check for coverage: `tool_group()` (tools/ops.rs), `StoreInitPlan` (runtime/context.rs) and `DomainSubscriberPlan` (core/jsonrpc.rs). Adding a variant compiles cleanly while leaving a tool ungated or a store unkeyed — and both failure modes have now shipped: - `harness_init` sat in `Platform`, so `DomainSet::harness()` never registered it: an agent harness that does not run harness init (fixed in #5332). - `tool_group`'s `Inference` rule matched `tokenjuice_`, but that is a migration alias — the live tool is `tinyjuice_retrieve` (vendor/tinyjuice/src/cache/marker.rs:11). CCR retrieval was therefore falling through to `Platform`, staying callable under `DomainSet { platform: true, inference: false }` and vanishing under `harness()`. Shipped by me in #5332 and found by this guard while writing it. The Inference rule now matches against the crate's own `RECOVERY_TOOL_NAMES` constant instead of a guessed prefix, so it cannot drift to a stale alias again. Enforcement chain, rooted so the lists cannot silently rot: `DomainGroup::index()` is an exhaustive match, so a new variant is a compile error there first; `domain_group_all_lists_every_variant` then fails until `ALL` and `COUNT` catch up. The three guards iterate `ALL` and force every variant into exactly one of two lists (owns-a-store / storeless, registers-subscribers / none, owns-tools / tool-less), so adding a family cannot compile-and-forget. The tool guard deliberately tests the FUNCTION, not a built registry. My first version asserted over `default_tools()`, which returns three tools, and then over the widest registry — but registry contents depend on config flags, security tier and enabled integrations, so it passed or failed for reasons unrelated to group mapping. It now checks one representative name per family, with `representative_tool_names_are_real` keeping that table honest against the real registry. Verified the guard is not vacuous by reintroducing the `tokenjuice_` bug and confirming it fails with the expected message, then restoring. Verified: default, --all-targets, gates-off, Tauri-shell builds clean; clippy -D warnings clean in both Cargo worlds; fmt clean; core:: 684 gates-on / 564 gates-off; tools 868 passed with --test-threads=1. Noted while here, not fixed: `default_tools_omits_flows_tools_when_feature_off` asserts absence from the three-tool `default_tools()` list, so it is trivially true and proves less than it appears to.

It asserted "at least half the representative names are registered" — an arbitrary threshold that is feature-dependent by construction. Gates-off only 8 of 18 resolve (the rest belong to compiled-out families), so it failed for a reason that has nothing to do with drift. 2. Worse, building a registry via `integration_tools_for_config` mutates process-global state, which broke a NEIGHBOURING test: `all_tools_executes_google_places_family_against_fake_backend` started failing with "tool `google_places_search` not registered" in the gates-off build. Verified as my regression, not pre-existing — it passes on clean `origin/main` gates-off and failed on this branch. Removed. The main guard already catches table rot for every non-`Platform` entry by construction: rename a tool and `tool_group` stops matching it, returns `Platform`, and the `assert_eq!` fails. The one blind spot is the `("shell", Platform)` row, where a rename still "matches" the fallthrough — documented in the guard's doc comment along with why building a real registry to close it is not worth the global-state pollution. Verified in BOTH feature configurations this time: default → tools 867, core 684; gates-off → tools 767 (serial and parallel), core 564. Builds, clippy -D warnings, and fmt clean.
