Summary

Two focused test files for previously untested pure functions:

preflight-resolveRuntime.test.ts

Tests resolveRuntime from deploy-preflight.ts — the template-id → runtime-name mapper. 16 cases covering:

All 6 explicit runtime-map entries (langgraph, claude-code-default→claude-code, openclaw, deepagents, crewai, autogen)
Identity fallback for modern/unknown template ids
-default suffix stripping (trailing only, not leading)
Edge cases: empty string, bare -default, multiple -default suffixes

canvas-topology-pure.test.ts

Tests 5 pure utility functions from canvas-topology.ts:

sortParentsBeforeChildren: topological sort ensuring parents precede children, orphan handling, non-mutating, no-op for already-sorted, dedup guard, missing-parent safety
defaultChildSlot: 2-column grid coordinates for slots 0–4
childSlotInGrid: variable-size siblings, uniform-grid equivalence, column-width = max sibling width
parentMinSize: 0–5 children, grid dimension calculations
parentMinSizeFromChildren: variable sizes, empty array, width/height monotonicity

Test plan

npx tsc --noEmit — no new type errors in these files
Local vitest blocked by QEMU bus error — CI is canonical runner

## Summary Two focused test files for previously untested pure functions: ### preflight-resolveRuntime.test.ts Tests `resolveRuntime` from `deploy-preflight.ts` — the template-id → runtime-name mapper. 16 cases covering: - All 6 explicit runtime-map entries (`langgraph`, `claude-code-default`→`claude-code`, `openclaw`, `deepagents`, `crewai`, `autogen`) - Identity fallback for modern/unknown template ids - `-default` suffix stripping (trailing only, not leading) - Edge cases: empty string, bare `-default`, multiple `-default` suffixes ### canvas-topology-pure.test.ts Tests 5 pure utility functions from `canvas-topology.ts`: - `sortParentsBeforeChildren`: topological sort ensuring parents precede children, orphan handling, non-mutating, no-op for already-sorted, dedup guard, missing-parent safety - `defaultChildSlot`: 2-column grid coordinates for slots 0–4 - `childSlotInGrid`: variable-size siblings, uniform-grid equivalence, column-width = max sibling width - `parentMinSize`: 0–5 children, grid dimension calculations - `parentMinSizeFromChildren`: variable sizes, empty array, width/height monotonicity ## Test plan - [x] `npx tsc --noEmit` — no new type errors in these files - Local vitest blocked by QEMU bus error — CI is canonical runner

- preflight-resolveRuntime.test.ts: resolveRuntime from deploy-preflight.ts
  covering explicit runtime-map entries, identity fallback, -default suffix
  stripping, edge cases (empty string, multiple suffixes).
- canvas-topology-pure.test.ts: sortParentsBeforeChildren (topological
  sort, orphan handling, no-op, non-mutating), defaultChildSlot (2-col
  grid), childSlotInGrid (variable-size siblings, uniform-grid fallback),
  parentMinSize (0–5 children, grid dimensions), parentMinSizeFromChildren
  (variable sizes, empty array, width/height correctness).

Review — PR #236 (resolveRuntime, canvas-topology tests)

Found 1 failing test:

`sortParentsBeforeChildren > does not crash when parentId references a missing node`

Test expects result.map(n => n.id) === ["root", "orphan"] but gets ["orphan", "root"]. The algorithm iterates nodes in input order and outputs in order visited (DFS with visited set). Since orphan appears first in the input, it's output first regardless of parent resolution. The implementation is correct — it preserves input iteration order. Fix: update the expected order to ["orphan", "root"] to match input iteration order, or rewrite the test input array to put root first.
