From bcc8bf17c1dca1a9ee3eb589735d493846df1c8e Mon Sep 17 00:00:00 2001 From: gsxdsm Date: Thu, 30 Jul 2026 13:01:54 -0700 Subject: [PATCH] fix(core): brand the unregistered built-in workflow fallback (#2815) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit > **Corrected after opening.** The first version of this PR claimed the id cross-check reported `"default"` for *every* authored workflow and stranded cards in triage recovery forever. That was wrong, and the correction is below in full. The reachable defect is the branding hole; removing the id check is correctness, not a live bug fix. ## The bug (reachable) `resolveWorkflowIrById` has four ways to substitute the default coding IR. Three brand the result via `markFellBack`. The fourth did not: ```ts if (isBuiltinWorkflowId(workflowId)) { const builtin = getBuiltinWorkflow(workflowId); const ir = builtin?.ir ?? defaultCodingWorkflowIr(); // <- unmarked substitution ``` An id that *looks* built-in but is not registered — a workflow removed between releases, a typo'd selection — lands there and silently gets the default coding IR. `resolveWorkflowIrForTaskWithProvenance` then reports **`source: "selection"`** for it, handing a caller the default board's graph under the selected workflow's name. That is precisely the lying signal the API exists to prevent. Found by review on this PR (thanks — see the thread), not by me. ## The correction to my own claim I also deleted an id cross-check that ran after the marker check and reported `"default"` when the resolved IR's `id` differed from the requested workflow id. I justified that by saying it misfired for every authored workflow, because `createWorkflowDefinition` stores an IR verbatim while minting `WF-NNN` separately: ``` store workflow id = WF-001 stored ir.id = custom:prov PROVENANCE source = default resolved ir.id = custom:prov <- the CORRECT IR, called a guess ``` **That measurement is real but it came from this suite's own fixture.** Neither `WorkflowIrV1` nor `WorkflowIrV2` declares an `id` field. An editor-authored workflow carries none, so `resolvedId` is `undefined` and the check passed it as `"selection"` — the misfire never reached `triage.ts`'s post-U11 intake recovery, the one production consumer. My "declined forever, not deferred" claim does not hold. Removing the check is still right: it is **unreliable** (it interrogates a property the IR types do not declare, and when one is present it is the author's id, unrelated to the store-minted row id) and **redundant** (all four substitutions are now branded, and the marker is checked first). But it is a cleanup, not a fix — and saying otherwise is how a narrow change gets backported as a critical one. ## Tests | case | asserts | |---|---| | unregistered **built-in** id | **`source: "default"`** — the reachable defect | | missing definition | still `"default"` | | no selection | still `"default"` | | IR carrying its own id | `"selection"`, with the id mismatch asserted explicitly so it can't pass for the wrong reason | | the resolved IR is the task's own board | contains the renamed hold column, not a default-board id | **Mutation-verified:** removing only the branding fails the unregistered-builtin case and nothing else — which shows it covers that specific hole rather than overlapping the others. Restoring the id check fails only the carries-its-own-id case, leaving both fallback cases green, which shows the deletion did not widen trust. ## Blast radius `triage.ts:1211` is the only production consumer of the provenance result across core, engine, dashboard and CLI. Every other `.source ===` hit is an unrelated field on an unrelated type; the two index hits are re-exports. ## Verification - new suite — **5/5**, mutation-verified in both directions - `pnpm test:gate` — **exit 0** - `pnpm lint` — clean Changeset included (`patch`, category `fix`), rewritten to describe the branding fix rather than the overstated one. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5 (1M context) --- .changeset/provenance-identity-misfire.md | 7 + .../workflow-ir-resolution-provenance.test.ts | 80 +++++++++- packages/core/src/workflow-ir-resolver.ts | 94 ++++++++--- ...workflow-ir-provenance-live-e2e.pg.test.ts | 151 ++++++++++++++++++ 4 files changed, 307 insertions(+), 25 deletions(-) create mode 100644 .changeset/provenance-identity-misfire.md create mode 100644 packages/engine/src/__tests__/workflow-ir-provenance-live-e2e.pg.test.ts diff --git a/.changeset/provenance-identity-misfire.md b/.changeset/provenance-identity-misfire.md new file mode 100644 index 0000000000..bd823babac --- /dev/null +++ b/.changeset/provenance-identity-misfire.md @@ -0,0 +1,7 @@ +--- +"@runfusion/fusion": patch +--- + +summary: Fix an unregistered built-in workflow id being trusted as a real selection. +category: fix +dev: `resolveWorkflowIrById` substituted the default coding IR for an id that looks built-in but is not registered, without branding it as a fallback, so `resolveWorkflowIrForTaskWithProvenance` reported `source: "selection"` for it.
