-Received: "# Debugging\n\nYou are a hypothesis-driven debugger. Two disciplines apply regardless of language, runtime, or whether you have source:\n\n1. **Runtime truth beats code reading.** Every claim about why the bug happens must come from observed state — never from a plausible story spun from reading code.\n2. **Leave no trace.** Debugging creates artifacts. Every artifact is journaled and removed before you call the task done.\n\nThe rest of this file is a map. **The knowledge is in `references/`.** This file cannot teach you how to debug — it can only tell you which reference will, for your exact situation.\n\n---\n\n# 🚨 READ THE REFERENCES. THIS IS NOT OPTIONAL.\n\n> **This skill is intentionally small.** Ninety percent of what you need to know lives in `references/`. If you skim this file and start working without opening the references, you will reattach a debugger the wrong way, miss a silent-failure pattern you've never seen before, waste an hour on a source-map gotcha, or invent a worse version of a tool that already solves your problem.\n>\n> **Every reference below is mandatory when its scenario applies.** \"I know this language\" is not an exemption. The references exist because every runtime and every specialist tool has at least one gotcha that silently wastes hours, and you will not know which gotcha until you read the file.\n>\n> **The gate rule**: before you run a command from a given reference's domain, you must have read that reference in this session. Re-reading across sessions is cheap. Guessing is expensive.\n\n---\n\n## Runtime Setup — MANDATORY READING BEFORE ATTACHING\n\nThe methodology is language-agnostic. The commands to launch, attach, breakpoint, and inspect are not. **Open the matching reference before Phase 0. Not during. Not after.**\n\n| Your runtime is… | Open this before attaching anything | Non-negotiable because… |\n|---|---|---|\n| Python (CPython, pytest, asyncio, Django, FastAPI) | 📖 **[references/runtimes/python.md](references/runtimes/python.md)** | pdb vs ipdb vs debugpy vs pytest --pdb all have different attach semantics. Async code needs special breakpoint handling. Wrappers like `poetry run` swallow flags. |\n| Node.js / tsx / ts-node / Bun / Deno (running source) | 📖 **[references/runtimes/node.md](references/runtimes/node.md)** | `tsx` + `node inspect` CLI has a **silent source-map failure** — breakpoints by line number do not fire. You will not notice unless you read this first. |\n| Rust (cargo, tokio, panics) | 📖 **[references/runtimes/rust.md](references/runtimes/rust.md)** | Release builds strip symbols. Tokio tasks need `tokio-console`. The borrow checker makes `dbg!` the faster tool most of the time. |\n| Go (goroutines, dlv, pprof, race) | 📖 **[references/runtimes/go.md](references/runtimes/go.md)** | Goroutine leaks and recovered panics are silent by default. `dlv` has a specific port convention. `go test -race` is the first thing to run, not the last. |\n| Native binary / stripped C/C++ / no source | 📖 **[references/runtimes/native-binary.md](references/runtimes/native-binary.md)** | The workflow (triage → dynamic → static → scripted repro) is counterintuitive if you've never done it. `strings -n 8` silently drops short interpolations like `${x}` — read bytes directly for any extraction that matters. macOS adds SIP / Mach-O / lldb specifics that don't apply on Linux. |\n| **Bundled-app binary** (Bun SEA, Node SEA, Deno compile, pkg, nexe, Electron, Tauri, PyInstaller) | 📖 **[references/runtimes/bundled-js-binary.md](references/runtimes/bundled-js-binary.md)** | These look like Mach-O / ELF but their *high-level* source is recoverable with the right per-bundler tool — Ghidra is overkill. Source-format reality varies: Bun/pkg/nexe/Electron-asar are usually plaintext; Node SEA with code-cache, PyInstaller `.pyc`, and Deno eszip need extra tooling; Tauri's Rust core still needs native-binary.md. Workflow: identify bundler → locate bundle → extract with the bundler-specific tool → grep. |\n\n...\n\n 7312 pass\n 1 skip\n 2 fail\n 24 snapshots, 16703 expect() calls\nRan 7315 tests across 744 files.

+## [2026-05-21] BOULDER COMPLETE
+
+All 40 plan checkboxes resolved (40 [x], 0 [ ], 1 [~] deferred for T6 lsp-core).
+
+**Final commits on dev (since baseline 6609d90b3):**
+- Wave 1: utils package extraction + W1-QA APPROVE
+- Wave 2: model-core, rules-engine, agents-md-core, ast-grep-core, comment-checker-core, boulder-state extractions + W2-QA APPROVE (T6 deferred)
+- Wave 3: meta-audits + opencode-coupling grep gate + AGENTS.md/ROADMAP docs + W3-QA APPROVE
+- Final Wave round 1: F2 + F3 APPROVE; F1 + F4 REJECT
+- Round 2 fixes: FIX-1 (model-core DI eliminated 4 back-imports), FIX-2 (14 evidence sentinels), FIX-3 (T4 doc edit split)
+- Final Wave round 2: F1 + F4 surface 2 new issues
+- Round 3 fixes: FIX-5 (audit allowlist for runtime.Bun.* dual-runtime pattern), FIX-6 (delete 855KB dead generated JSON)
+- Final state: all 4 reviewers APPROVE
+
+**Test baseline preserved exactly: 7314 pass / 1 skip / 2 fail / 7317 total**
+- 2 fails are pre-existing skill-content ambiguous short-name tests (untouched by refactor)
+- 1 documented flake: tmux runner test under heavy parallel I/O (passes 9/9 in isolation)
+
+**Architecture delivered:**
+- 7 Core packages in packages/ (utils, model-core, rules-engine, agents-md-core, ast-grep-core, comment-checker-core, boulder-state)
+- Per-file re-export shims at original src/ locations (never `export *`)
+- opencode-coupling-audit.test.ts enforces zero Bun.* or src/ coupling in package production code (test files exempt)
+- ProviderCache, ConnectedProvidersAdapter, SpawnFn DI interfaces for harness independence
+- API designed for future pi/codex adoption
+
+**Deferred future tracks:**
+- T6 lsp-core extraction (submodule strategy)
+- Pi adapter layer (senpi + extensions)
+- Codex adapter layer
+- rules-engine full Engine DI (originally planned in T4, scoped to rename only)
+- 3 orphan re-export shims for cleanup (apply-patch-edits.ts, model-capability-aliases.ts, model-capability-guardrails.ts)
+- Tmux runner test flake (documented)
+
+**Key learnings:**
+- Subagents running bash inherit the parent's cwd, NOT the worktree path — must use `workdir` parameter explicitly. FIX-6 subagent deleted from main repo by accident before catching this.
+- Coupling audit regex `\bBun\.` is too broad; negative lookbehind `(?<!runtime\.)\bBun\.` correctly distinguishes legitimate dual-runtime shim from production violations.
+- Test files importing test data from outside the package are acceptable — audit must exclude `*.test.ts` to avoid false positives.
+- Git worktrees + cherry-pick is the cleanest parallel-work pattern when subagents work on independent fixes.
+- Subagent overconfidence: marks "done" even when typecheck failures persist; orchestrator-side verification is non-negotiable.
