Release v1.3.0 — Parallel Execution Hardening · farshidghyasi/spec-engine

What's New in v1.3.0

Addresses 10 critical parallel execution issues and adds behavioral guardrails inspired by the superpowers plugin methodology.

Import manifest generation — before each wave, scan completed task files and build a manifest of exact export names. Agents use correct imports instead of guessing.
Cross-agent import resolution — after parallel agents complete, verify imports match actual exports before merging.
Auto-commit worktrees — orchestrator auto-commits after each agent using only the task's declared files.
Shared file enforcement — unauthorized modifications to shared files (app.ts, routers, etc.) are automatically reverted before merge.

Integration smoke test — new integration_cmd quality gate runs after each wave. On failure, rolls back the entire wave and re-runs sequentially.
Wired status verification — automatically grep app entry points to verify wired: "yes" claims. Downgrades to pending if no import found.

Diff mode — quality gates compare error counts against a baseline, so pre-existing failures don't mask new errors. New baseline_errors field in state.json.
Post-merge command verification — failures in post-merge commands are now blocking errors.
Wave numbering — Wave: field is now the sole source of truth; removed wave numbers from section headers.

Rationalization prevention tables in spec-loop and spec-exec — every skippable step now has an explicit "you will think X, reality is Y" entry drawn from real production failures.
Verification iron law in spec-implementer and spec-tester — no completion claims without fresh evidence (grep output, test output, wiring chain confirmation). Tester independently verifies wired status instead of trusting implementer.
Structured 4-phase debugging in spec-debugger — replaces "fix it" with: Investigate → Analyze → Hypothesize → Implement. Requires root cause identification before any code changes. Includes red flags list for stopping and re-investigating.
