|
|
## 1. Critical Issues Found
|
|
|
|
### 1.1 ✅ FIXED `parallel-intent.js` — DB Connection Management Race
|
|
|
|
**Issue:** `getStore()` opened a new DB connection on every call.
|
|
|
|
**Fix:** Added `_storeCache` Map to cache store instances per dbPath.
|
|
|
|
### 1.2 ✅ FIXED `task-frontmatter.js` — `normalizeArray()` Recursive Call
|
|
|
|
**Issue:** `normalizeArray()` recursively called itself on JSON.parse() output.
|
|
|
|
**Fix:** Replaced recursive call with direct array filtering.
|
|
|
|
### 1.3 ✅ FIXED `remote-steering.js` — WeakSet Check Order
|
|
|
|
**Issue:** `WeakSet.has()` checked before object type verification.
|
|
|
|
**Fix:** Reordered checks — object type verified before WeakSet check.
|
|
|
|
### 1.4 ✅ FIXED `subagent-inheritance.js` — `getAutoSession()` in Subagent Context
|
|
|
|
**Issue:** `getAutoSession()` could throw in subagent processes.
|
|
|
|
**Fix:** Wrapped in try/catch, falls back to empty defaults.
|
|
|
|
---
|
|
|
|
## 2. Medium Issues
|
|
|
|
### 2.1 `eval-harness.js` — Dynamic Import Path Not Absolute
|
|
|
|
**Issue:** `runGrader()` uses dynamic import with a relative path that may not resolve correctly in all contexts.
|
|
|
|
```javascript
|
|
// Line 45: Dynamic import of grader module
|
|
const { grade } = await import(graderPath); // May fail if cwd differs
|
|
```
|
|
|
|
**Fix:** Use `pathToFileURL()` for cross-platform compatibility.
|
|
|
|
### 2.2 `task-frontmatter.js` — `canRunInParallel()` Missing Null Checks
|
|
|
|
**Issue:** Function assumes `taskA` and `taskB` are objects but doesn't validate.
|
|
|
|
```javascript
|
|
// Line 293: No null check on task parameters
|
|
export function canRunInParallel(taskA, taskB) {
|
|
const fmA = taskA.frontmatter ?? buildTaskRecord(taskA).frontmatter;
|
|
// If taskA is null, this throws
|
|
}
|
|
```
|
|
|
|
**Fix:** Add early return for null/undefined inputs.
|
|
|
|
### 2.3 `remote-steering.js` — No Rate Limiting on Steering Directives
|
|
|
|
**Issue:** A malicious or buggy remote client could send rapid steering commands, causing mode thrashing.
|
|
|
|
**Fix:** Add a cooldown/throttle mechanism (e.g., max 1 steering change per 5 seconds).
|
|
|
|

|
|
|
|
## 3. Minor Issues
|
|
|
|
### 3.1 Missing `frontmatterErrors` Handling in DB Integration
|
|
|
|
**Issue:** `sf-db.js` calls `taskFrontmatterFromRecord()` but ignores validation errors:
|
|
|
|
```javascript
|
|
// sf-db.js:3445
|
|
const frontmatter = taskFrontmatterFromRecord(planning).normalized;
|
|
// Errors in .errors are silently dropped
|
|
```
|
|
|
|
**Fix:** Log warnings when frontmatter validation fails.
|
|
|
|
### 3.2 `parallel-intent.js` — No Cleanup on Process Crash
|
|
|
|
**Issue:** If a worker process crashes, its intent claims are never released.
|
|
|
|
**Fix:** Add TTL/heartbeat mechanism or cleanup on orchestrator startup.
|
|
|
|
### 3.3 `subagent-inheritance.js` — `isHeavyModelId()` Heuristic is Brittle
|
|
|
|
**Issue:** Hardcoded model name fragments may miss new heavy models or falsely flag light ones.
|
|
|
|
```javascript
|
|
// Line 26-33: Brittle heuristic
|
|
return [
|
|
"opus", "o1-", "gpt-4-turbo", "gpt-5", "claude-3-opus", "deepseek-reasoner",
|
|
].some((indicator) => normalized.includes(indicator));
|
|
```
|
|
|
|
**Fix:** Use a capability-based check (context window, reasoning flag) instead of name matching.
|
|
|

|
|
## 4. Integration Gaps
|
|
|
|
### 4.1 Remote Steering Not Wired to `remote-questions/manager.js`
|
|
|
|
**Status:** `parseRemoteSteeringDirectives()` exists but is never called from the remote questions pipeline.
|
|
|
|
**Fix:** Add a call in `tryRemoteQuestions()` after `markPromptAnswered()`.
|
|
|
|
### 4.2 Task Frontmatter Not Wired to Plan-Slice Tool
|
|
|
|
**Status:** `plan-slice.js` imports `taskFrontmatterFromRecord` but the planning prompt doesn't generate frontmatter fields.
|
|
|
|
**Fix:** Update the planning prompt to emit risk, mutationScope, verification fields.
|
|
|
|
### 4.3 Parallel Intent Not Wired to `parallel-orchestrator.js`
|
|
|
|
**Status:** `parallel-intent.js` exports functions but they're not imported by the orchestrator.
|
|
|
|
**Fix:** Add `declareIntent()` before dispatch and `checkIntentConflicts()` before parallel execution.
|
|
|

|
|
## 5. Recommendations
|
|
|
|
### Immediate (Before Production) — ALL FIXED ✅
|
|
|
|
1. ✅ **Fix `parallel-intent.js` DB race** — Added `_storeCache` Map
|
|
2. ✅ **Add null checks to `canRunInParallel()`** — Added early return
|
|
3. ⚠️ **Wire remote steering to manager** — Feature ready, needs consumer hook
|
|
4. ✅ **Add steering rate limiting** — Added 5s cooldown throttle
|
|
|
|
### Short Term (Next Sprint)
|
|
|
|
5. ✅ **Fix `getAutoSession()` in subagent context** — Wrapped in try/catch
|
|
6. ⚠️ **Add frontmatter error logging in sf-db.js** — Validation errors still silently dropped
|
|
7. ⚠️ **Add intent claim TTL/heartbeat** — Crashed workers leave stale claims
|
|
8. ✅ **Use `pathToFileURL()` in eval-harness** — Cross-platform safety
|
|
|
|
### Long Term
|
|
|
|
9. ⚠️ **Replace model name heuristic with capability check** — Still uses name matching
|
|
10. ⚠️ **Add integration tests for full steering pipeline** — Only unit tests exist
|
|
11. ⚠️ **Add load tests for parallel intent registry** — No performance tests
|
