From 28a8205645dc6284222d878dc6a8de954b2eeb62 Mon Sep 17 00:00:00 2001 From: Fusion Agent Date: Tue, 25 Aug 2026 23:40:38 +0000 Subject: [PATCH] fix(FN-WF): run the Verification gate instead of silently passing it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Your Verification step completed in 46ms and reported PASS without executing anything. It had never run. `GateNodeRunner` recognised exactly two executable shapes, `prompt` and `scriptName`. A gate carrying `workflowAction: "deterministic-verification"` matched neither and fell through to the method's closing `return success`. The code that runs testCommand/buildCommand was never reached — so the strictest gate in the review lane was decorative, and it was supplying the merge evidence a task is allowed to rely on. The existing unit tests were green throughout, because every one of them called `runDeterministicVerificationGate` directly. Testing a function proves the function; it does not prove the graph calls it. The new wiring suite asserts the routing itself and fails when the fix is removed — verified by removing it. DRY: `verification-gate.ts` re-derived the command list and re-ran the loop, a second implementation of a rule that `runExecutorDeterministicVerification` (FN-3345, run-implementation.ts) already owned. The two had already drifted — the copy treated "no command configured" as a hard failure while the original treats it as not-applicable. The gate now delegates, so timeouts, per-command logging, and settings precedence can only be fixed in one place. NOT in this change, and deliberately so: recording an unrunnable gate as `skipped` rather than `passed`. It is the right model and it was implemented end-to-end, but `pre-merge-approval` clears a `skipped` step only for an audited operator bypass, so it made every task on a project without a test command unmergeable — 25 of 90 smoke tests. Narrowing the acceptance left one unexplained failure (S09 sentinel, 120s timeout). Shipping that half-understood would trade a visible false green for an invisible merge deadlock. FN-189 owns it with the full evidence. pnpm lint 0 errors, test:gate, engine-pipeline-smoke 90/90, and three consecutive full runs: 150.9s, 152.8s, 154.5s of the 175s budget. --- .changeset/verification-gate-never-ran.md | 7 ++ .../pipeline-smoke/_pipeline-harness.ts | 11 +- .../review-gated-verification-gate.test.ts | 113 +++++++++++++---- .../src/executor/run-graph-custom-node.ts | 2 +- .../src/workflow-node-runners/gate-runner.ts | 13 +- .../verification-gate.ts | 115 ++++++++++-------- 6 files changed, 180 insertions(+), 81 deletions(-) create mode 100644 .changeset/verification-gate-never-ran.md diff --git a/.changeset/verification-gate-never-ran.md b/.changeset/verification-gate-never-ran.md new file mode 100644 index 0000000000..815dfe3e66 --- /dev/null +++ b/.changeset/verification-gate-never-ran.md @@ -0,0 +1,7 @@ +--- +"@runfusion/fusion": patch +--- + +summary: Fix a Verification gate that reported PASS without running your tests. +category: fix +dev: `GateNodeRunner` recognised only `prompt` and `scriptName` as executable shapes, so a gate carrying `workflowAction` fell through to a silent `return { outcome: "success" }` — deterministic Verification completed in ~46ms and recorded a pass without executing anything, supplying merge evidence for a check that never ran. `verification-gate.ts` now delegates to `runExecutorDeterministicVerification`, the same primitive the in-progress executor gate has always used, instead of re-deriving the command list.
