+# Fix Pre-existing Test Failures
+
+**Date:** 2026-02-22
+**Status:** Proposed
+**Problem:** Multiple tests fail on macOS across several packages. All failures reproduce
+on `upstream/main` — they are not regressions from local changes.
+
+## Failures
+
+### 1. macOS symlink path mismatch
+
+**Tests:**
+- `TestResolveDetachedPaths_ConvertsRelativeToAbsolute` (`cmd/kilroy/detach_paths_test.go`)
+- `TestLoadProjectDocs_WalksFromGitRootToWorkingDir_InDepthOrder` (`internal/agent/project_docs_test.go`)
+
+**Root cause:** On macOS, `/var/folders` is a symlink to `/private/var/folders`.
+`t.TempDir()` returns the symlink path (`/var/...`) but `filepath.Abs()` and
+`git rev-parse --show-toplevel` resolve through symlinks, returning `/private/var/...`.
+Assertions compare these unequal strings and fail.
+
+**Fix:** Normalize both sides of path comparisons with `filepath.EvalSymlinks()`:
+
+```go
+// detach_paths_test.go
+tempDir, _ := filepath.EvalSymlinks(t.TempDir())
+```
+
+For `project_docs_test.go`, the same symlink issue likely causes
+`dirsFromRootToCwd()` to produce a mismatched path list. Apply
+`filepath.EvalSymlinks` to the git root and working directory before computing
+the relative path.
+
+**Files to modify:**
+- `cmd/kilroy/detach_paths_test.go`
+- `internal/agent/project_docs.go` or `internal/agent/project_docs_test.go`
+
+---
+
+### 2. Preflight tests missing API key env vars
+
+**Tests:**
+- `TestRunWithConfig_WarnsWhenCLIModelNotInCatalogForProvider` — google/BackendAPI, no `GEMINI_API_KEY`
+- `TestRunWithConfig_WarnsWhenAPIModelNotInCatalogForProvider` — openai/BackendAPI, no `OPENAI_API_KEY`
+- `TestRunWithConfig_WarnsAndContinues_WhenProviderNotInCatalog` — cerebras/BackendAPI, sets `CEREBRAS_API_KEY` but `report.Summary.Fail != 0`
+- `TestRunWithConfig_ForceModel_BypassesCatalogGate` — openai/BackendAPI, no `OPENAI_API_KEY`
+- `TestRunWithConfig_AllowsKimiAndZai_WhenCatalogUsesOpenRouterPrefixes` — sets kimi/zai keys but cerebras is pulled in via failover chain synthesis
+
+**Root cause:** These are NOT integration tests — other similar tests in the same file
+use `t.Setenv("OPENAI_API_KEY", "k-test")` to satisfy the `provider_api_credentials`
+preflight check. The failing tests were likely updated to use `BackendAPI` (to isolate
+catalog checks from CLI binary presence) but the corresponding `t.Setenv` calls for the
+required API key env vars were not added.
+
+For the kimi/zai test, `resolveProviderRuntimes()` synthesizes builtin failover targets
+recursively (provider_runtime.go:91-123). This pulls cerebras into the runtime map via
+kimi or zai's builtin failover chain. The `usedAPIProviders()` function then traverses
+failover chains and includes cerebras in the preflight check list, but no
+`CEREBRAS_API_KEY` is set.
+
+**Fix:** Add the missing `t.Setenv` calls:
+
+```go
+// TestRunWithConfig_WarnsWhenCLIModelNotInCatalogForProvider
+t.Setenv("GEMINI_API_KEY", "k-test")
+
+// TestRunWithConfig_WarnsWhenAPIModelNotInCatalogForProvider
+t.Setenv("OPENAI_API_KEY", "k-test")
+
+// TestRunWithConfig_ForceModel_BypassesCatalogGate
+t.Setenv("OPENAI_API_KEY", "k-test")
+
+// TestRunWithConfig_AllowsKimiAndZai_WhenCatalogUsesOpenRouterPrefixes
+t.Setenv("CEREBRAS_API_KEY", "k-test")  // pulled in via failover chain
+```
+
+For the cerebras/WarnsAndContinues test, verify whether the existing
+`t.Setenv("CEREBRAS_API_KEY", "k-cerebras")` is sufficient or if additional
+failover-chain providers also need keys.
+
+**Files to modify:**
+- `internal/attractor/engine/provider_preflight_test.go`
+
+---
+
+### 3. Reference template missing postmortem prompt attribute
+
+**Test:**
+- `TestReferenceTemplate_PostmortemPromptClarifiesStatusContract` (`internal/attractor/validate/reference_template_guardrail_test.go`)
+
+**Root cause:** The reference template (`skills/english-to-dotfile/reference_template.dot`)
+defines `postmortem []` with no attributes. A comment on line 281 says
+"Note: status reflects analysis completion, not implementation state" but that is a DOT
+comment, not a node attribute. The test expects `pm.Attr("prompt", "")` to contain
+"whether you completed the analysis".
+
+**Fix:** Add a `prompt` attribute to the postmortem node in `reference_template.dot`
+that includes the required phrase. The prompt should instruct the LLM that the status
+field reflects whether the analysis was completed, not whether the implementation succeeded.
+
+**Files to modify:**
+- `skills/english-to-dotfile/reference_template.dot`
+
+---
+
+### 4. Process group termination (flaky / environment-specific)
+
+**Tests:**
+- `TestWaitWithIdleWatchdog_ContextCancelKillsProcessGroup` (`internal/attractor/engine/codergen_process_test.go`)
+- `TestRunProviderCapabilityProbe_RespectsParentContextCancel` (`internal/attractor/engine/provider_preflight_test.go`)
+- `TestEnsureCXDBReady_AutostartProcessTerminatedOnContextCancel` (engine package)
+
+**Root cause:** These tests verify that child processes are killed when context is
+canceled. They fail intermittently, likely due to timing sensitivity — the process
+group signal may not propagate to grandchild processes quickly enough, or background
+processes spawned by shell scripts escape the process group.
+
+**Recommendation:** Investigate whether these are genuinely flaky or indicate a real
+process-management gap. If flaky, increase timeouts or add retry logic in the assertions.
+If real, improve `terminateProcessGroup()` / `forceKillProcessGroup()` to handle
+grandchild processes.
+
+**Files to investigate:**
+- `internal/attractor/engine/codergen_process.go`
+- `internal/attractor/engine/provider_preflight.go`
+
+## Priority
+
+1. Preflight missing env vars (bug, easy fix)
+2. macOS symlink normalization (bug, easy fix)
+3. Reference template postmortem prompt (incomplete template)
+4. Process group termination (needs investigation)
