From c7d75fed19389b231503fbf03143c5a2d5229595 Mon Sep 17 00:00:00 2001 From: "Molecule AI Dev Engineer B (MiniMax)" Date: Mon, 15 Jun 2026 00:26:06 +0000 Subject: [PATCH] refactor(workspace-server): SSOT consolidation for BYO-compute meta-runtimes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per PM-triage approval (bounded-fill, low-priority): consolidate the BYO-compute meta-runtime set (external, kimi, kimi-cli) into a single SSOT. Before this PR the same 3 names were hardcoded in 4 separate sites with 3 different shapes: 1. runtime_registry.go:76-88 fallbackRuntimes map (3 entries) 2. runtime_registry.go:109-122 loadRuntimesFromManifest injection 3. runtime_registry.go:144 isExternalLikeRuntime switch 4. workspace.go:400 error message string literal Adding a new BYO-compute meta-runtime required updating all 4 sites in lockstep; missing one was a silent drift surface. Now a single var externalLikeRuntimes = []string{"external", "kimi", "kimi-cli"} drives all 4. CHANGES ======= 1. runtime_registry.go: new const-style var externalLikeRuntimes is the SINGLE source of truth. fallbackRuntimes builds itself from externalLikeRuntimes + the (intentionally-separate) mock entry. loadRuntimesFromManifest injects the SSOT into its result map the same way. isExternalLikeRuntime converts from a hardcoded switch to a loop over the SSOT. New helper joinExternalLikeRuntimesForMessage() builds the Oxford-comma "external", "kimi", or "kimi-cli" string from the SSOT. 2. workspace.go:400: the 422 error body now uses fmt.Sprintf("external workspaces must use runtime %s", joinExternalLikeRuntimesForMessage()) so the user-facing string derives from the SSOT. A future SSOT change auto- propagates to the error message. 3. runtime_registry_test.go: new TestExternalLikeRuntimesConsistent pin test locks the resolved shape across all 4 sites. Asserts (a) externalLikeRuntimes length and order match {"external", "kimi", "kimi-cli"}; (b) fallbackRuntimes contains the SSOT + claude-code/hermes/openclaw/codex/mock; (c) isExternalLikeRuntime returns true for each SSOT entry and false for template-backed runtimes + unknown; (d) joinExternalLikeRuntimesForMessage() produces the exact wire shape "external", "kimi", or "kimi-cli"; (e) the full error string is preserved verbatim. BEHAVIOR-PRESERVING ==================== The pin test asserts identical resolved shapes before and after the consolidation: - fallbackRuntimes has the same 8 entries (4 template-backed + 3 external-like + mock) - loadRuntimesFromManifest injects the same 4 entries (3 external-like + mock) + the manifest-backed entries - isExternalLikeRuntime returns the same boolean for every runtime input (loop vs switch is mechanical) - The user-facing error message produces the same string for the same runtime set No API contract change, no migration, no test deletion, no caller update. Drift guard (the new pin test) PREVENTS future drift, doesn't fix existing bugs. VERIFICATION ============ - go build ./... clean - go vet ./internal/handlers/ clean - gofmt -l clean - go test ./internal/handlers/ 25.3s, all green - TestExternalLikeRuntimesConsistent PASS - All 5 existing TestLoadRuntimesFromManifest_* / TestInitTemplateRepoByName_* tests pass unchanged OUT OF SCOPE ============ - Canvas TS RUNTIME_OPTIONS list (out of lane for a Go-side bounded fill) - Renaming "mock" into the external-like set (intentionally separate — mock is virtual-only, never user-selected, has different semantics around A2A replies) Routes to 1-genuine (low-priority; will not block the security / main-red queue). Per PM: "the review jam is capacity, not PR-count, so one more low-pri queued PR doesn't hurt". No self-merge. --- .../internal/handlers/runtime_registry.go | 115 ++++++++++++++---- .../handlers/runtime_registry_test.go | 92 ++++++++++++++ .../internal/handlers/workspace.go | 6 +- 3 files changed, 188 insertions(+), 25 deletions(-) diff --git a/workspace-server/internal/handlers/runtime_registry.go b/workspace-server/internal/handlers/runtime_registry.go index 317b50165..844ba7576 100644 --- a/workspace-server/internal/handlers/runtime_registry.go +++ b/workspace-server/internal/handlers/runtime_registry.go @@ -26,6 +26,7 @@ package handlers import ( "encoding/json" + "fmt" "log" "os" "path/filepath" @@ -67,25 +68,82 @@ type manifestFile struct { WorkspaceTemplates []manifestEntry `json:"workspace_templates"` } +// joinExternalLikeRuntimesForMessage returns the runtime list as it +// appears in user-facing error messages, e.g. `"external", "kimi", or +// "kimi-cli"`.
