+//   • extensions        — set-union across all three layers (order preserved: user, then repo-extras, then cli-extras)

+//                          layer's "enabled" (disabled wins, per plan)

+//   • `_`-prefixed keys in user/repo/cli config are dropped during merge
+//     (reserved for OPC provenance output: `_source`, `_paths`, future `_*`).
+//   • `__proto__`, `constructor`, `prototype` are dropped at every merge level
+//     to prevent prototype-chain pollution of the returned merged object.
+//
+// Input validation:
+//   • Non-object JSON (array, string, number, null) at any layer is rejected

examples/extensions/_starter/README.md

+# `_starter` — drop-in OPC extension template
+
+> Copy this directory, change one field, run one command, ship.
+
+---
+
+## 1. What this is (30-second pitch)
+
+`_starter/` is the canonical, **zero-dependency**, copy-paste skeleton for a
+new OPC extension. It contains:
+
+- `ext.json` — the manifest
+- `hook.mjs` — all five hooks (`startupCheck`, `promptAppend`,
+  `verdictAppend`, `executeRun`, `artifactEmit`) stubbed to their
+  graceful-empty return values, with `// TODO(starter):` markers at every
+  decision point
+- `README.md` — this file
+
+Every hook is wired to **return cleanly** the moment you copy it, so
+`opc-harness extension-test --all-hooks` exits 0 before you've written a
+line of business logic. You can iterate one hook at a time without
+breaking the rest of the pipeline.
+
+If you're new to OPC extensions, read
+[`docs/extension-authoring.md`](../../../docs/extension-authoring.md) first
+— that doc is the reference; this template is the on-ramp.
+
+---
+
+## 2. Copy + rename recipe
+
+Pick a name in `kebab-case`. **The directory name IS the canonical extension
+name** — it's what the loader reads (`bin/lib/extensions.mjs:366-368,453`),
+and what shows up in logs, failure sidecars, and artifact subdirs as
+`ext-<name>/`. `ext.json.name` is NOT read by the loader; just name the
+directory what you want the extension called.
+
+Locate the starter (pick whichever path exists on your box):
+
+```bash
+# If you installed the skill globally:
+STARTER=~/.claude/skills/opc/examples/extensions/_starter
+# Or from a repo checkout:
+# STARTER=/path/to/opc-checkout/examples/extensions/_starter
+# Or via npm global install:
+# STARTER="$(npm root -g)/@touchskyer/opc/examples/extensions/_starter"
+[ -d "$STARTER" ] || { echo "can't find _starter — clone the opc repo first"; exit 1; }
+
+# Copy into the OPC extensions dir (OPC_EXTENSIONS_DIR overrides ~/.opc/extensions).
+cp -r "$STARTER" "${OPC_EXTENSIONS_DIR:-$HOME/.opc/extensions}/my-ext"
+cd "${OPC_EXTENSIONS_DIR:-$HOME/.opc/extensions}/my-ext"
+```
+
+That's it. The extension is now discoverable as `my-ext`.
+
+> **Pre-flight:** the headline `opc-harness extension-test` command in §4
+> is available on the bundled harness (`node <opc-repo>/bin/opc-harness.mjs`).
+> Globally-installed binaries from brew or older npm tags may predate the
+> extension loader and will silently print a usage banner + exit 0 instead
+> of running the subcommand. If `opc-harness extension-test --help` prints
+> the generic banner, use the bundled path explicitly:
+> `node ~/.claude/skills/opc/bin/opc-harness.mjs extension-test …`.
+
+---
+
+## 3. Edit checklist
+
+Open the two files in this order. Touch only what you need; the defaults
+are safe.
+
+### 3.1 `ext.json`
+
+`ext.json` is **descriptive only** — the loader never parses it (only `hook.mjs`
+is imported). Package indexes and `opc-harness config resolve` may read it for
+human-visible fields.
+
+| Field                          | What to set                                                              |
+|--------------------------------|--------------------------------------------------------------------------|
+| `version`                      | Your extension's version. Informational only.                            |
+| `description`                  | One-line human summary. Shown by tooling; keep `meta.description` in `hook.mjs` in sync. |
+| `meta.provides`                | The capability you provide, in `name@N` format. **Required in `hook.mjs`.** |
+| `meta.compatibleCapabilities`  | Older capability generations you also respond to. Optional.              |
+
+> The loader reads `meta` from `hook.mjs`, not `ext.json`. The table above is
+> for human readers + tooling only; only the values inside `hook.mjs` affect
+> routing. Keep them in sync for hygiene.
+
+`name@N` rules (lifted from `extension-authoring.md` §4.1):
+
+- Lowercase ASCII letter start, then `[a-z0-9-]*`
+- Literal `@`
+- Positive integer (no `@0`, no leading zeros, no semver ranges)
+
+Examples: `visual-check@1`, `a11y-audit@2`. Bare `foo` is auto-upgraded to
+`foo@1` with a one-time stderr WARN — declare `foo@1` explicitly to silence
+it.
+
+> **Why both `provides` and `compatibleCapabilities`?** During capability
+> migrations (say, `visual-check@1` → `visual-check@2`), put the new
+> generation in `provides` and the old one in `compatibleCapabilities` so
+> nodes on either side keep matching.
+
+### 3.2 `hook.mjs`
+
+The file is organised so you can implement hooks one at a time:
+
+1. **`startupCheck`** — fastest win. If your extension needs an env var or
+   an external CLI, probe it here. **Never throw** unless you genuinely
+   want the extension disabled for the whole process.
+2. **`promptAppend`** — most common first hook. Returns markdown to append
+   to the role prompt.
+3. **`verdictAppend`** — evaluator-phase findings. Returns an array.
+4. **`executeRun`** — executor-phase side effects (Playwright, curl, etc.).
+   Return value is ignored.
+5. **`artifactEmit`** — executor-phase file emission. Returns
+   `[{ name, content }]`; each lands at `<runDir>/ext-<name>/<name>`.
+
+**You can delete any hook you don't need.** The loader treats missing
+exports as "not implemented" — there is no runtime cost. Deleting unused
+hooks is the recommended way to trim the file once you know what you're
+shipping.
+
+Search the file for `TODO(starter):` — every marker is a decision point.
+Replace each one with your logic, or delete the surrounding hook.
+
+---
+
+## 4. Test it
+
+From the OPC repo root (or wherever `opc-harness` is on your `PATH`):
+
+```bash
+# Lint manifest + run the three hooks `--all-hooks` covers
+# (startup.check, prompt.append, verdict.append).
+opc-harness extension-test \
+  --ext "${OPC_EXTENSIONS_DIR:-$HOME/.opc/extensions}/my-ext" \
+  --all-hooks
+```
+
+Expected output: a `✅` line per hook. **Exit code must be 0.** `[lint]`
+lines only appear when capability strings fail validation. A non-zero exit
+means the extension failed to load (missing `hook.mjs`, bad JSON in
+`--context`, etc.) — fix that before touching hook bodies.
+
+To exercise `executeRun` or `artifactEmit`, name the hook explicitly and
+provide a writable `runDir`:
+
+```bash
+opc-harness extension-test \
+  --ext "${OPC_EXTENSIONS_DIR:-$HOME/.opc/extensions}/my-ext" \
+  --hook artifact.emit \
+  --context '{"runDir":"/tmp/opc-smoke","nodeCapabilities":["my-capability@1"]}'
+```
+
+(`--all-hooks` deliberately skips `execute.run` / `artifact.emit` because
+they need a real `runDir`. See `docs/extension-authoring.md` §9.)
+
+---
+
+## 5. Common pitfalls — "why isn't my hook firing?"
+
+The four scenarios that account for ~all "silently no-op" reports:
+
+1. **Capability mismatch.** The node's `nodeCapabilities` does not
+   intersect `meta.provides ∪ meta.compatibleCapabilities`. Routing is
+   case-sensitive exact-string after normalization. Verify with
+   `opc-harness config resolve` (lists loaded extensions and their
+   provides) and double-check the node's required capabilities in the
+   flow template.
+
+2. **Wrong export name.** Unknown exports are silently ignored. A typo
+   like `prommptAppend` will load fine and never fire. Cross-check exports
+   against the §1.2 mapping table — the canonical names are
+   `promptAppend`, `verdictAppend`, `executeRun`, `artifactEmit`,
+   `startupCheck`.
+
+3. **Empty / missing `nodeCapabilities` in `ctx`.** When
+   `ctx.nodeCapabilities` is missing, empty, or not an array, **no**
+   extensions fire for that call site. When testing via
+   `extension-test --context '...'`, include
+   `"nodeCapabilities": ["my-capability@1"]`.
+
+4. **Circuit breaker tripped.** Three consecutive failures (throw /
+   timeout / wrong-shape return) in a single process disable the
+   extension for the rest of the run. Look for a `CIRCUIT-BREAKER` line
+   on stderr and an `extension-failures.md` next to the run dir. Fix the
+   root cause; the breaker resets the next time the harness boots.
+
+---
+
+## 6. Next steps
+
+- **Read** [`docs/extension-authoring.md`](../../../docs/extension-authoring.md)
+  end-to-end. It is the source of truth for hook contracts, timeouts,
+  the failure sidecar, and the circuit breaker.
+- **Study** [`examples/extensions/memex-recall/`](../memex-recall/) — the
+  canonical "smallest real extension" with caching, own-timeouts, and
+  graceful degradation.
+- **Borrow** the graceful-degradation template in
+  `extension-authoring.md` §6 the moment you start calling external CLIs
+  or hitting the network.
+
+Ship it.

examples/extensions/README.md

+# OPC Extensions — Starter
+
+This directory used to host 6 reference extensions. Per the original
+extension-system design spec (§1: *"Extensions live in the user's home
+directory, never in OPC source"*), the real extensions now live in a
+private repo and install into `~/.opc/extensions/`.
+
+## What remains here
+
+- [`_starter/`](./_starter/) — the canonical scaffold for authoring a
+  new extension. Copy to `~/.opc/extensions/<your-ext>/` and edit.
+
+## Where the real extensions live
+
+Everything else (design-lint, visual-eval, memex-recall,
+git-changeset-review, session-logex, lint-prompt-length) migrated out of
+this repo in OPC v0.8.x. They live alongside their paired skills in a
+private repo:
+
+```
+git clone [e-mail]:iamtouchskyer/opc-extensions.git ~/Code/opc-extensions
+cd ~/Code/opc-extensions
+./install.sh
+```
+
+If you're an open-source user of OPC and don't have that repo, OPC
+still works — extensions are strictly optional. The core harness has no
+dependency on any extension; activation is pure capability-contract
+intersection (see `docs/specs/2026-04-16-opc-extension-system-design.md`).
+
+## Authoring your own
+
+1. `cp -R examples/extensions/_starter ~/.opc/extensions/my-ext`
+2. Edit `hook.mjs` — declare `meta.provides`, implement whichever hooks
+   you need (`promptAppend`, `verdictAppend`, `executeRun`,
+   `artifactEmit`).
+3. Verify:
+   ```bash
+   opc-harness extension-test --ext ~/.opc/extensions/my-ext --lint-strict
+   opc-harness extension-test --ext ~/.opc/extensions/my-ext --all-hooks \
+     --context '{"nodeCapabilities":["your-capability@1"]}'
+   ```
+4. Done — OPC picks it up on next flow run, gated by capability match.

examples/runbooks/add-feature-replay.md

+# Mental Replay — `/opc loop add a dark-mode toggle`
+
+Dry walkthrough of how the reference runbook fires end-to-end. No code
+was run for this artifact beyond `opc-harness runbook match`; everything
+else is narrative. The goal is to pressure-test the Step 0 wiring added
+in U5.11 by imagining a realistic run.
+
+## Setup
+
+Assume the user has:
+- Cloned OPC at `~/.claude/skills/opc/`
+- Symlinked the reference runbook:
+  ```bash
+  mkdir -p ~/.opc/runbooks
+  ln -s ~/.claude/skills/opc/examples/runbooks/add-feature.md \
+        ~/.opc/runbooks/add-feature.md
+  ```
+- Is in a project repo that already has a test suite + dev server.
+
+Invocation:
+
+```
+/opc loop add a dark-mode toggle
+```
+
+## Tick sequence
+
+### Tick 0 — Runbook lookup + plan seed
+
+The orchestrator reads `skill.md` + `pipeline/loop-protocol.md`. Per
+the new Step 0, before decomposition it shells out to:
+
+```bash
+opc-harness runbook match "add a dark-mode toggle"
+```
+
+Verified output (live, with `~` substituted for the absolute home path
+in the rendered transcript below for portability):
+
+```json
+{
+  "task": "add a dark-mode toggle",
+  "dir": "~/.opc/runbooks",
+  "matched": true,
+  "score": 5,
+  "patterns": ["/\\badd\\s+(a|an|the)\\s+\\w+/i"],
+  "runbook": {
+    "id": "add-feature",
+    "flow": "build-verify",

+    "units": ["spec", "plan", "build", "review", "fix",
+              "test-design", "test-execute", "acceptance", "e2e"],
+    ...
+  }
+}
+```
+
+The orchestrator skips Step 1 (decomposition) and writes
+`.harness/plan.md` directly from the runbook. Header:
+
+```markdown
+# Plan — add a dark-mode toggle
+Seeded from runbook `add-feature` (score 5, pattern:
+`/\badd\s+(a|an|the)\s+\w+/i`).
+
+## Units
+- U1 spec — acceptance criteria, DoD
+- U2 plan — per-unit verify/eval lines
+- U3 build — implementer subagent
+- U4 review — 2 independent reviewers (frontend + a11y)
+- U5 fix — address 🔴/🟡
+- U6 test-design — E2E scenarios + axe scan design
+- U7 test-execute — orchestrator runs the plan
+- U8 acceptance — PM sign-off
+- U9 e2e — new-user + active-user personas
+```
+
+Cron (`*/10 * * * *`, durable) scheduled. First tick executes
+immediately.
+
+### Tick 1 — U1 spec
+
+Orchestrator reads baseline from `pipeline/quality-tiers.md` for tier
+`polished` and writes `.harness/acceptance-criteria.md`:
+
+- [ ] Dark + light theme pass visual review
+- [ ] Theme toggle persists across page reload
+- [ ] Responsive at 375 / 768 / 1280 widths
+- [ ] Loading / error / empty states covered
+- [ ] Focus styles on every interactive element
+- [ ] axe-core clean (no critical/serious)
+- [ ] `prefers-color-scheme` media query honored on first load
+- [ ] Keyboard-accessible toggle (Tab + Space/Enter)
+
+`criteria-lint` passes (all 14 mechanical checks). Commit.
+
+### Tick 2 — U2 plan
+
+Per-unit verify/eval lines added to `plan.md`. E.g.:
+
+```markdown
+- U3 build — implement dark-mode toggle
+  - verify: `npm test -- --grep "theme"` passes; `npm run build` clean
+  - eval: no hardcoded colors in JSX, CSS custom properties used for
+    theme tokens, toggle state persisted in localStorage
+```
+
+### Tick 3 — U3 build
+
+Implementer subagent dispatched via `superpowers:subagent-driven-development`.
+Writes:
+- `src/contexts/ThemeContext.tsx`
+- `src/components/ThemeToggle.tsx`
+- CSS token layer (`:root { --bg: … }`, `[data-theme="dark"] { --bg: … }`)
+- Hooks into root layout
+
+Tests added for `ThemeToggle` + context. Git HEAD changes (required by
+harness).
+
+### Tick 4 — U4 review
+
+Orchestrator dispatches **2 Agent-tool subagents in parallel**:
+- `frontend` role — reviews component structure, CSS token usage
+- `a11y` role — reviews focus styles, contrast ratios, ARIA
+
+Both produce `eval-frontend.md` + `eval-a11y.md` with 🔴/🟡/🔵. Example
+finding: 🟡 "Toggle button missing `aria-pressed`." `synthesize`
+produces verdict `ITERATE`.
+
+### Tick 5 — U5 fix
+
+Direct fix (no subagent). Adds `aria-pressed`, re-runs tests. Git HEAD
+changes.
+
+### Tick 6 — U6 test-design
+
+Different subagent (`tester` role) designs but does NOT run:
+- E2E: toggle click, verify `[data-theme]` attribute flips
+- E2E: reload, verify theme persists
+- E2E: `prefers-color-scheme: dark` system pref honored on first load
+- axe scan at both theme states
+
+### Tick 7 — U7 test-execute
+
+Orchestrator runs the plan using `webapp-testing` + `npx playwright`.
+Captures screenshots at both themes (artifact required for UI units).
+axe scan: 0 critical/serious.
+
+### Tick 8 — U8 acceptance
+
+`pm` + `designer` subagents. Both sign off.
+
+### Tick 9 — U9 e2e
+
+Orchestrator runs `new-user` + `active-user` persona walkthroughs per
+`executor-protocol.md`. Evidence captured.
+
+### Tick 10 — Terminate
+
+`next-tick` returns `terminate: true`. Backlog drain: 1 🔵 suggestion
+from U4 review — "consider honoring `prefers-reduced-motion` for the
+theme-switch CSS transition." Below drain threshold (🔵 only), rolled
+to final summary. Cron cancelled. `.harness/report.html` generated.
+
+## What the walkthrough proves
+
+1. **Step 0 actually fires** — `opc-harness runbook match` returns a
+   match for "add a dark-mode toggle" via the `\badd\s+(a|an|the)\s+\w+\b`
+   regex. Verified live in this session.
+2. **The runbook overrides decomposition** — tick 0 skips Step 1 and
+   adopts the runbook's 9-unit sequence wholesale. Saves one LLM round.
+3. **Tier propagates** — `polished` triggers the baseline a11y /
+   responsive / state-coverage checks automatically, without the user
+   repeating them in the task.
+4. **Review independence is preserved** — the runbook's `units:` list
+   keeps `build` and `review` as separate ticks (the prime directive).
+   The runbook doesn't let a user accidentally flatten them.
+5. **Fall-through works** — if a task like "fix a memory leak" doesn't
+   match any runbook (`runbook match` returns exit 3), Step 1
+   decomposition runs as before. Zero regression for the
+   no-runbook path.
+
+## Known limitations observed
+
+- Score 5 (regex-only match) is low. A runbook with more specific
+  keywords would score higher and win against competing runbooks in a
+  multi-runbook setup. For v1 that's fine — the tie-breakers handle it.
+- The runbook's `match` list is tuned for English. A Chinese task like
+  "添加一个暗色模式" would not match. Future work (U6+): bilingual
+  keyword support or per-project runbook override.
+- `--no-runbook` is documented in loop-protocol but not yet wired into
+  `/opc loop` CLI parsing. The wired escape hatch is the env var
+  `OPC_DISABLE_RUNBOOKS=1`, which `runbook match` honors as of U5.12r
+  (returns exit 3 with `disabled: true` in the payload). Verified live.
+
+## Coherence check
+
+Read `pipeline/loop-protocol.md` top-to-bottom after the Step 0 insert:
+
+- Intro says flows handle single cycles, loop sits above them ✓
+- Terminology block distinguishes Flow vs Runbook ✓
+- Runbook Discovery section now references the CLI discovery order ✓
+- Procedure: Step 0 (new) → Step 1 decompose → Step 2 init state ✓
+- Tick prompt template unchanged (ticks don't care how the plan was
+  seeded) ✓
+
+Reads coherently — the insertion is not a bolt-on paragraph.

+# Add Feature — Reference Runbook
+
+The canonical recipe for "add a feature to an existing codebase." Ship
+this in `.opc/runbooks/` (or `~/.opc/runbooks/`) and any `/opc loop`
+whose task phrase contains `add feature` / `new feature` /
+`implement feature` (or starts with `implement`) will use this unit
+structure instead of decomposing from scratch.
+
+## Why these units
+
+The separation is not cosmetic — each unit enforces the OPC prime
+directive: **the agent that does the work never evaluates it.**
+
+- **spec** — pin acceptance criteria before any code. Tier is
+  `polished` (UI work), so baseline items (dark/light, responsive,
+  loading/error/empty, focus styles) are mandatory.
+- **plan** — decompose the feature into concrete DoD bullets.
+  Verify/eval lines per sub-task written to `.harness/plan.md`.
+- **build** — implementer subagent writes the code.
+- **review** — ≥2 independent reviewers (typically frontend +
+  backend, or frontend + a11y for pure UI). Dispatched via Agent
+  tool, never self-review.
+- **fix** — address 🔴 + 🟡 findings from review. A separate tick so
+  the fix is a standalone commit and git bisect stays useful.
+- **test-design** — a different subagent designs test cases without
+  running them (API tests, E2E UI scenarios, edge cases, a11y).
+- **test-execute** — orchestrator runs the designed plan and captures
+  evidence (test output, screenshots, a11y scan results).
+- **acceptance** — PM/designer sign-off against the spec's DoD.
+- **e2e** — new-user + active-user personas walk the full flow.
+
+## When to deviate
+
+- **Simple UI tweak** → drop `spec` + `e2e`, keep
+  `plan/build/review/fix/test-execute`.
+- **Pure backend feature** → drop `e2e` (executor-protocol handles
+  API verify via test-execute), keep the rest.
+- **Complex subsystem** → insert a `design` unit between `spec` and
+  `plan` to brainstorm architecture.
+
+Override this runbook at invocation time by setting
+`OPC_DISABLE_RUNBOOKS=1` before the harness call (forces match-miss
+without scanning disk). To use a project-local variant, copy this file
+to your project (or any directory) and point `OPC_RUNBOOKS_DIR` at it
+— the CLI resolves `--dir` flag → `OPC_RUNBOOKS_DIR` env var →
+`~/.opc/runbooks/` (default), in that order. There is no automatic
+project-local `.opc/runbooks/` discovery today.
+
+## Match patterns
+
+The `match:` list is case-insensitive whole-word:
+
+- `add feature` — scores 20 (2 words × 10)
+- `new feature` — scores 20
+- `implement feature` — scores 20
+- `add a feature` — scores 30 (3 words × 10) — wins against the
+  2-word phrases when the task is verbose
+- `/^implement /i` — regex for "implement anything" (scores 5). Lower
+  than keyword matches so a more specific phrase wins if both fire.
+
+Tags `build` and `frontend` contribute +3 each if they appear as
+whole words in the task (e.g., "add a new build step" would pick up
+the `build` tag).
+
+## Acceptance criteria (baseline subset)
+
+A representative subset derived from the `polished` tier. The full
+checklist (typography, navigation, code blocks, tables, favicon,
+smooth-scroll, etc.) lives in `pipeline/quality-tiers.md` — when this
+runbook fires, the orchestrator's quality-tier expansion picks up
+*all* polished items, not just the ones below. The bullets here are
+illustrative of what an `add a dark-mode toggle` task would surface
+first.
+
+- [ ] Dark + light theme pass visual review
+- [ ] Responsive at 375 / 768 / 1280 widths (extend to 320/1024/1440 per
+      tier baseline)
+- [ ] Loading / error / empty states covered
+- [ ] Focus styles on every interactive element
+- [ ] No console errors / warnings
+- [ ] a11y: axe-core clean (no critical/serious violations)

roles/skeptic-owner.md

+---
+
+# Skeptic Owner
+
+## Identity
+
+Mechanism auditor who **does not trust that anything works as designed**. Not reviewing code quality — reviewing whether the system will actually be used correctly by its real consumers (humans, LLMs, cron jobs, CI pipelines).
+
+Where devil-advocate challenges *decisions*, skeptic-owner challenges *mechanisms*: "You decided X, fine — but will X actually happen in production?"
+
+**Core behavioral rules:**
+
+1. **Assume every instruction will be ignored** — if behavior isn't enforced in code, it doesn't exist. "The docs say to do X" is not evidence that X happens.
+2. **Trace the real consumer path** — who is the actual user? What's their path of least resistance? Will they do what you expect, or take the shortcut?
+3. **Demand E2E evidence** — unit tests passing ≠ system works. Show the full path: trigger → transform → output → cleanup.
+4. **Question the lifecycle** — creation is the easy part. Who cleans up? What if cleanup fails? What happens after 1000 runs?
+5. **Every finding must have a code lever** — if there's no code-level fix possible, say so explicitly and classify as 🔵. Don't waste cycles on pure LLM-compliance issues unless you can propose a mechanical guardrail.
+
+## Expertise — 6 Skepticism Dimensions
+
+### D1: Silent Fallback Detection
+The most dangerous bug is a silent wrong default. System appears to work but uses stale data / wrong dir / default config. These survive all tests because tests don't know what the *right* answer is.
+
+**Test**: For every function with a default/fallback value, ask: "If the fallback fires when it shouldn't, would anyone notice?"
+
+### D2: Enforcement vs Documentation
+"Is this enforced in code or just documented?" If only documented, it doesn't exist. This includes LLM prompt instructions — if the LLM can skip step 1 and go straight to step 3, it will.
+
+**Test**: For every design invariant, trace the enforcement path. If it terminates at a prompt instruction with no code-level fallback, flag it.
+
+### D3: Integration Boundary Skepticism
+Two components both work in isolation. Do they actually connect? Is the contract (file format, path convention, flag name) the same on both sides?
+
+**Test**: For every cross-component contract (paths, flags, JSON schemas), grep both sides and verify they match literally, not just conceptually.
+
+### D4: Lifecycle & Accumulation
+Creation → usage → update → cleanup → failure recovery. Most systems implement creation and usage. Cleanup is "TODO". Quantify: N per day × size × retention. If unbounded, it's a bug.
+
+**Test**: For every persistent artifact (file, dir, DB row, cron job, symlink), answer: "Who deletes this, when, and what if deletion fails?"
+
+### D5: E2E Trigger-to-Artifact Verification
+Each node passing individually ≠ the chain works. Trigger the top, observe the bottom.
+
+**Test**: For pipeline/integration tasks, the only valid evidence is: trigger the first event, observe the last artifact changing within N seconds.
+
+**E2E Verification Checklist** (execute this, don't just describe it):
+1. **Identify trigger**: what command / webhook / cron / UI action starts the chain?
+2. **Identify terminal artifact**: what file / API response / log line / DB row proves the chain completed?
+3. **Capture before-state**: `stat`, `hash`, `curl`, or `query` the terminal artifact before triggering
+4. **Execute trigger**: run the actual command or fire the actual event
+5. **Poll terminal artifact**: within a defined timeout (e.g., 30s), check that the artifact changed
+6. **Capture evidence**: save before/after diff, command output, or screenshot as `e2e-evidence-{N}.txt`
+7. **If no E2E path exists**: state explicitly "No E2E path — unit/integration evidence only" with justification
+
+Proxy evidence (unit tests passing, individual node PASS) is **insufficient** — it must be supplemented with at least one trigger-to-artifact trace, or an explicit annotation why E2E is not applicable.
+
+### D6: Consumer Mismatch
+The system was designed for user A but the actual consumer is user B (LLM that takes shortcuts, CI that runs headless, junior dev who copies the first example).
+
+**Test**: List every consumer type. For each, trace the actual invocation path. Does the interface match their behavior?
+
+---
+
+## When to Include
+
+**Auto-select when:**
+- Any system that will be consumed by LLMs (skills, prompts, tool interfaces, CLI wrappers)
+- Lifecycle-sensitive features (anything that creates persistent state)
+- When the design relies on consumers following multi-step instructions
+- Infrastructure changes (session management, file layout, config resolution, deployment pipelines)
+
+**Include at these node types:**
+- **review / code-review** — audit mechanisms: "Is this enforced in code or just documented?"
+- **acceptance** — production readiness: "Would this survive 1000 runs without human intervention?"
+
+**Skip:**
+- **discussion** nodes — no mechanisms to audit yet; let devil-advocate handle feasibility challenges
+- **build** nodes — don't review implementation details; that's other reviewers' job
+- **gate** nodes — mechanical, no subagent dispatch
+
+## Evaluation Focus
+
+For each design element, pick the 2-3 most relevant dimensions and go deep. Priority:
+1. D1 (Silent fallback) + D2 (Enforcement) — highest-impact failures
+2. D3 (Integration boundaries) + D5 (E2E trigger) — for multi-component systems
+3. D4 (Lifecycle) — for anything that creates persistent state
+4. D6 (Consumer mismatch) — if consumers are LLMs or non-expert
+
+## Anti-Patterns
+
+| Shortcut | Why it's wrong | Do this instead |
+|----------|---------------|-----------------|
+| "The LLM should follow the prompt" | LLMs take shortcuts. That's physics. | Propose a code-level fallback for when the prompt is ignored (D2) |
+| "Tests pass so it works" | Tests prove the happy path in isolation | Demand E2E evidence from the real consumer path (D5) |
+| Flagging issues without code levers | Findings without fixes are lower priority | Mark as 🔵, state "no code lever", and deprioritize (don't suppress) |
+| Reviewing code style or naming | That's other reviewers' job | Focus on mechanism: does the system enforce what it promises? (D2) |
+| "This could theoretically fail" without scenario | Vague paranoia is noise | Construct: under condition X, consumer Y will do Z, resulting in W |
+| Fixing the same problem twice with same approach | Treating symptoms, not root cause | Ask: "If this fix is ignored, does the problem recur?" |
+
+## Output Format
+
+### Mechanism Audit
+
+For each finding:
+
+```
+### 🔴/🟡/🔵 [{OPEN|SEALED}] {one-line summary}
+
+**Dimension**: D{N} — {dimension name}
+**Mechanism**: {what's supposed to happen}
+**Reality**: {what actually happens / will happen}
+**Consumer**: {who is affected — LLM, human, CI, cron}
+→ Reasoning: {why this matters, what's the impact}
+→ Fix: {specific code change, or "no code lever — 🔵 observation only"}
+**Evidence**: {how to verify — specific command, E2E test, or scenario}
+```
+
+Severity mapping:
+- 🔴 = Silent failure / system produces wrong results without error
+- 🟡 = Mechanism gap with a code-level fix available
+- 🔵 = Observation / no code lever / low priority
+
+### Lifecycle Check
+
+For systems that create persistent state, always include:
+
+```
+### Lifecycle: {component}
+- Creation: {who/when/how}
+- Cleanup: {who/when/how — or "MISSING"}
+- Failure recovery: {what happens on crash mid-operation — or "UNKNOWN"}
+- Accumulation rate: {N per day/session, disk impact}
+```
+
+## Verdict
+
+- `VERDICT: MECHANISMS HOLD` — all enforcement paths verified with evidence. PASS.
+- `VERDICT: GAPS FOUND [N]` — N mechanisms have code-level fixes available. 🟡 ITERATE.
+- `VERDICT: SILENT FAILURE` — system appears to work but produces wrong results silently. 🔴 FAIL.

+# Thorough Code Review
+
+## Architecture
+The codebase follows a clean layered architecture with clear separation of concerns.
+Models are well-defined with proper TypeScript types.
+Services abstract business logic from route handlers.
+
+## Findings
+
+🔵 src/main.ts:10 — Import ordering inconsistent
+→ Group external imports before internal ones
+Reasoning: Following the project's established convention in other files.
+
+🔵 src/utils.ts:25 — Unused helper function
+→ Remove `formatDate` — it's not called anywhere
+Reasoning: Dead code increases maintenance burden.
+
+🔵 src/db.ts:42 — Connection pool size hardcoded
+→ Move to environment variable
+Reasoning: Production environments may need different pool sizes.
+
+## Security
+No SQL injection vectors found. Input validation is proper.
+Authentication middleware is correctly applied to protected routes.
+CORS settings are appropriately restrictive.
+
+## Performance
+Database queries use proper indexing.
+No N+1 query patterns detected.
+Response caching is applied where appropriate.
+
+## Error Handling
+All async routes have try-catch blocks.
+Error responses include proper status codes and messages.
+Validation errors are distinguished from server errors.

+# Thorough Code Review
+
+## Architecture Analysis
+The codebase follows a well-structured MVC pattern.
+Dependency injection is used consistently.
+Module boundaries are clearly defined with explicit exports.
+
+## Security Assessment
+No SQL injection vectors found in database queries.
+Authentication middleware properly validates JWT tokens.
+CORS is configured to allow only approved origins.
+Input sanitization covers all user-facing endpoints.
+
+## Findings
+
+🔵 src/main.ts:10 — Import ordering inconsistent with project convention
+→ Group external imports before internal ones, alphabetize within groups
+Reasoning: Following the project's established convention seen in other files.
+
+🔵 src/utils.ts:25 — Unused helper function `formatDate` is dead code
+→ Remove `formatDate` — it's not called anywhere in the codebase
+Reasoning: Dead code increases maintenance burden and confuses new developers.
+
+🟡 src/auth.ts:42 — Token refresh window is too narrow (30s)
+→ Increase refresh window to 300s to prevent auth races
+Reasoning: Users with slow connections may lose their session during the refresh gap.
+
+🔵 src/db.ts:88 — Connection pool size hardcoded to 10
+→ Move to DATABASE_POOL_SIZE environment variable with default 10
+Reasoning: Production environments with higher traffic need larger pool sizes.
+
+## Performance Review
+Database queries use proper indexing on frequently queried columns.
+No N+1 query patterns detected in the ORM usage.
+Response caching is applied to read-heavy endpoints.
+Bundle splitting is configured for optimal loading.
+
+## Testing Assessment
+Unit test coverage is 85% for core business logic modules.
+Integration tests cover the four critical user flows.
+E2E tests verify the login-to-checkout journey end-to-end.
+Edge cases for concurrent operations need additional coverage.
+
+## Summary
+Found 4 issues: 1 warning (auth token refresh), 3 suggestions.
+Overall code quality is strong. The auth issue should be addressed
+before the next release to prevent user session drops.

+## Architecture
+Well-structured MVC pattern throughout the codebase.
+Clean module boundaries with explicit exports.
+Dependency injection is used consistently across services.
+
+## Findings
+
+🔵 src/main.ts:10 — Import ordering inconsistent with project convention
+→ Group external imports before internal ones, alphabetize within groups
+Reasoning: Following the project's established convention seen in other files.
+
+🔵 src/utils.ts:25 — Unused helper function formatDate is dead code
+→ Remove formatDate — not called anywhere in codebase
+Reasoning: Dead code increases maintenance burden.
+
+🟡 src/auth.ts:42 — Token refresh window is too narrow at 30 seconds
+→ Increase refresh window to 300s to prevent auth races
+Reasoning: Users with slow connections may lose their session.
+
+🔵 src/db.ts:88 — Connection pool size is hardcoded to 10
+→ Move to DATABASE_POOL_SIZE environment variable with default 10
+Reasoning: Production environments with higher traffic need larger pools.
+
+## Security
+No SQL injection vectors found in database query layer.
+Authentication middleware properly validates JWT tokens on protected routes.
+CORS is configured to allow only approved origins.
+Input sanitization covers all user-facing endpoints.
+
+## Performance
+Database queries use proper indexing on frequently queried columns.
+No N+1 query patterns detected in the ORM usage throughout.
+Response caching is applied to read-heavy endpoints.
+Bundle splitting is configured for optimal code loading.
+
+## Error Handling
+All async route handlers have try-catch blocks.
+Error responses include proper HTTP status codes.
+Validation errors distinguished from server errors.
+
+## Testing
+Unit test coverage at 85% for core business logic.
+Integration tests cover the four critical user flows.
+E2E tests verify login-to-checkout journey.
+
+## Summary
+Found 4 issues: 1 warning, 3 suggestions.
+Code quality is strong. Auth issue should be fixed before release.
+Overall patterns are consistent and well-maintained.

+# Comprehensive Code Review
+
+## Architecture Analysis
+
+🔵 src/auth/handler.ts:15 — Missing rate limiter on login endpoint
+
+**Reasoning:** Without rate limiting, brute-force attacks can enumerate credentials.
+
+**Fix:** Add express-rate-limit middleware with 5 attempts per 15 minutes.
+
+## Security Review
+
+🔵 src/db/queries.ts:42 — SQL query uses string concatenation
+
+**Reasoning:** Direct string interpolation in SQL enables injection attacks.
+
+**Fix:** Replace with parameterized queries using `$1, $2` placeholders.
+
+## Performance
+
+🟡 src/api/users.ts:88 — N+1 query pattern in user listing
+
+**Reasoning:** Each user triggers a separate profile fetch, causing O(n) queries.
+
+**Fix:** Use a single JOIN or batch query with `WHERE id IN (...)`.
+
+## Error Handling
+
+🔵 src/middleware/error.ts:12 — Stack traces exposed in production error responses
+
+**Reasoning:** Stack traces reveal internal paths and framework versions.
+
+**Fix:** Conditionally strip stack in production via `NODE_ENV` check.
+
+## Summary
+
+4 findings (1 warning, 3 suggestions). Auth rate limiting and SQL injection are the priority items.

+
+## Summary
+
+4 findings reviewed across security, performance, architecture, and testing.
+Code quality needs improvement in multiple areas.
+The application has several security concerns that need addressing.
+Performance bottlenecks identified in database layer.
+Test coverage is insufficient for critical paths.
+Architecture is reasonable but needs refinement.
+Recommended follow-up review after fixes are applied.
+Additional static analysis tools should be integrated.
+Consider implementing automated security scanning.
+Database query optimization should be prioritized.
+End of review.

+
+## Architecture
+
+🔵 src/handler.ts:15 — Missing input validation
+
+**Reasoning:** User input flows directly into business logic without sanitization.
+
+**Fix:** Add zod schema at the handler boundary.
+
+## Performance
+
+🟡 src/queries.ts:42 — Missing index on frequently queried column
+
+**Reasoning:** Full table scan on every request, O(n) degradation.
+
+**Fix:** `CREATE INDEX idx_users_email ON users(email);`
+
+## Error Handling
+
+🔵 src/middleware.ts:8 — Generic catch-all swallows specific errors
+
+**Reasoning:** Makes debugging impossible in production.
+
+**Fix:** Re-throw after logging, or use typed error classes.

+🟡 src/auth.ts:30 — Session token not rotated after login

+# ${role} Review
+## Architecture
+🔵 src/handler.ts:15 — Missing input validation
+Reasoning: User input flows directly to business logic without sanitization.
+→ Add zod schema validation at handler boundary.
+## Security
+🔵 src/auth.ts:22 — Weak password hashing
+Reasoning: Using MD5 which is cryptographically broken for passwords.
+→ Switch to bcrypt with cost factor 12.
+## Performance
+🔵 src/queries.ts:42 — Missing index on email column
+Reasoning: Full table scan on every user lookup request.
+→ CREATE INDEX idx_users_email ON users(email).
+## Error Handling
+🔵 src/middleware.ts:8 — Generic catch-all swallows errors
+Reasoning: All errors return 500, makes debugging impossible in production.
+→ Re-throw after logging, or use typed error classes with status codes.
+## Code Quality
+🔵 src/utils.ts:30 — Unused helper function formatDate
+Reasoning: Function is never imported in any other module.
+→ Remove dead code or mark as TODO if planned for future use.
+## Testing
+🔵 src/service.ts:55 — Missing edge case test coverage
+Reasoning: Empty input, null values, and boundary conditions not tested.
+→ Add test cases for each boundary condition.
+## Summary
+6 suggestions. All low-priority hardening items.
+Architecture is clean with good separation of concerns.
+No critical or warning-level issues found.

+
+## Context
+Reviewed the stylesheet for maintainability and consistency.
+Checked naming conventions, variable usage, and selector specificity.
+The codebase uses a mix of modules with varying maturity levels.
+Primary focus: tokens, layout, responsive behavior, and animation timing.
+Secondary focus: specificity, inheritance, and cascade interactions.
+
+## Methodology
+Walked through the stylesheet file by file noting patterns.
+Each section was examined for repetition that could be abstracted.
+Color values and spacing units received particular attention.
+Browser prefix coverage was cross-checked against caniuse data.
+Animation easing curves were verified against the design tokens.
+
+## Findings
+
+🔵 Consider using CSS variables — style.css:5 — hex color #3366cc appears 7 times
+→ Extract to --color-primary custom property declared at :root
+Reasoning: Centralizing color definitions makes theme updates trivial and prevents drift across components.
+
+## Positive Observations
+The selector specificity is generally well-controlled throughout the file.
+No !important declarations were found outside the reset block.
+Media queries are consistently ordered mobile-first with logical breakpoints.
+Animation durations use a reasonable set of values (100ms, 200ms, 400ms).
+Z-index values are clustered in recognizable ranges by layer role.
+Font stack declarations include appropriate fallbacks for all major platforms.
+Focus styles are present on every interactive element.
+Hover states respect the prefers-reduced-motion media query.
+
+## Areas Reviewed
+Color and typography tokens were audited against the design system.
+Layout and spacing systems use a consistent 4px base unit throughout.
+Component class naming follows a BEM-inspired convention reliably.
+Responsive breakpoint usage is consistent across pages and components.
+Animation and transition timing matches the documented motion tokens.
+Browser prefix coverage is appropriate for the stated support matrix.
+Custom scrollbar styles are gated behind feature detection.
+Print stylesheet is minimal but covers the critical reset cases.
+
+## Conclusion
+The stylesheet is in good shape overall and ready for the next release cycle.
+One minor optimization suggestion was noted above in the findings section.
+No blocking issues were identified during this pass of the codebase.
+The team has clearly invested in CSS architecture and it shows in the quality.

+# Security Review
+
+## Scope
+Reviewed authentication, authorization, input validation, and data storage.
+Scanned for OWASP Top 10 categories with a focus on injection and broken access control.
+Verified session and token lifecycle end-to-end for the critical user journeys.
+
+## Methodology
+Walked through each request handler end-to-end from entry to response.
+Cross-referenced with the existing security headers configuration file.
+Verified that secrets do not appear in logs or error messages on any path.
+Ran a static analysis sweep focused on taint sources and sinks in handlers.
+Checked that all outbound HTTP calls validate the target host before dispatch.
+
+## Areas Reviewed
+Session management and token handling across all authenticated endpoints.
+SQL query construction and parameterization in the data access layer.
+User input sanitization on all public-facing and internal-public endpoints.
+File upload handling, MIME validation, and storage path containment.
+Rate limiting configuration on authentication and password-reset endpoints.
+Outbound request validation to prevent server-side request forgery attacks.
+Cookie attributes including Secure, HttpOnly, SameSite, and Domain scope.
+Content Security Policy headers and their effective directives.
+
+## Positive Observations
+Password hashing uses a modern algorithm with appropriate cost factor.
+JWT tokens are signed with an asymmetric key and include sensible expiration.
+All database queries use parameterized statements via the ORM layer.
+CORS is configured narrowly to the known production and staging origins.
+Secrets are loaded from environment variables and are never logged.
+Security headers are applied consistently via middleware on every response.
+Error responses avoid leaking stack traces or internal identifiers.
+Session invalidation on logout clears both server and client state.
+
+## Cross-Cutting Concerns
+The team maintains a security posture document updated each release.
+Dependency scanning runs in CI and blocks merges on critical advisories.
+Penetration test findings from the last engagement have all been resolved.
+A threat model exists for the authentication subsystem and is current.
+
+## No Findings
+No critical, warning, or suggestion-level issues were found during this pass.
+The codebase demonstrates mature security hygiene across all surfaces reviewed.
+No follow-up actions are required from this review cycle at this time.
+
+## Summary
+The security review concluded without identifying any defects.
+The combination of architectural discipline and tooling investment shows.
+Recommendation is to proceed to the next stage of the release process.
+Continue current practices for dependency hygiene and CI security gates.
+A follow-up review of the new microservice is scheduled for next sprint.

+## Outcomes
+
+- OUT-1: All 3 fixtures load via extensionsDir.
+- OUT-2: ok-ext fires on every runtime hook (prompt/verdict/execute/artifact).

+- OUT-4: throw-ext trips the error breaker on verdict.append.
+- OUT-5: extension-failures.md lists both broken extensions with 🔴.
+
+## Verification
+
+- OUT-1: .ext-registry.json applied contains all 3 fixture names after init.
+- OUT-2: ok-ext-marker.txt exists in runDir/ext-ok-ext/ after extension-artifact.
+- OUT-3: extension-failures.md contains slow-ext + timeout marker.
+- OUT-4: extension-failures.md contains throw-ext + "intentional failure".
+- OUT-5: handshake.artifacts[] includes ok-ext's emitted artifact path.
+
+## Out of Scope
+
+- Testing core changes to extensionsApplied filtering (separate unit).
+- Performance or cross-platform behavior.
+
+## Quality Constraints
+
+- Test is hermetic: uses $TMP, no touch to ~/.opc or global state.
+- Deterministic: OPC_HOOK_TIMEOUT_MS pinned so slow-ext trips on every run.
+
+## Quality Baseline (functional)
+
+- Non-zero exit on any assertion failure.

+# to overwrite — which was the very bug U2.8a was supposed to fix.
+#
+# U2.8c switched writeFailureReport to a JSON sidecar architecture:
+#   - extension-failures.json is the canonical machine-readable source of truth
+#   - extension-failures.md is a derived view rendered from the sidecar
+#   - merge reads the sidecar (no parser/writer skew possible)

+## Summary
+Reviewed the authentication flow for common vulnerabilities.
+Checked for SQL injection, XSS, CSRF, and session fixation issues.
+
+## Findings
+🔵 suggestion — auth.js:42 — prefer const for immutable bindings
+→ Change `let user = ...` to `const user = ...`
+Reasoning: const signals immutability and enables compile-time checks.
+
+## Conclusion
+No critical security issues found. One style suggestion only.
+EVAL
+    cat > "$dir/nodes/$node/run_1/eval-performance.md" << 'EVAL'
+# Performance Review
+## Approach
+Profiled the hot path under typical load. Reviewed algorithmic complexity.
+Measured allocation patterns and database query counts.
+
+## Findings
+🔵 suggestion — handler.js:20 — cache the result of expensive computation
+→ Wrap the function in a memoize helper
+Reasoning: The same input is queried many times per request cycle.
+
+## Conclusion
+No performance regressions. One optimization opportunity noted.

+
+🔵 src/main.ts:10 — Import ordering inconsistent
+→ Group external imports before internal ones
+Reasoning: Following the project's established convention in other files.
+
+🔵 src/utils.ts:25 — Unused helper function
+→ Remove `formatDate` — it's not called anywhere
+Reasoning: Dead code increases maintenance burden.
+
+🔵 src/db.ts:42 — Connection pool size hardcoded
+→ Move to environment variable
+Reasoning: Production environments may need different pool sizes.
+
+## Summary
+
+Overall code quality is good. Three minor suggestions found, all style/cleanup.
+No critical or warning issues detected.

+# Thorough Code Review
+
+## Architecture
+The codebase follows a clean layered architecture with clear separation of concerns.
+
+## Findings
+
+🔵 src/main.ts:10 — Import ordering inconsistent
+→ Group external imports before internal ones
+Reasoning: Following the project's established convention in other files.
+
+🔵 src/utils.ts:25 — Unused helper function
+→ Remove `formatDate` — it's not called anywhere
+Reasoning: Dead code increases maintenance burden.
+
+🔵 src/db.ts:42 — Connection pool size hardcoded
+→ Move to environment variable
+Reasoning: Production environments may need different pool sizes.
+
+## Summary
+
+Overall code quality is good. Three minor suggestions found, all style/cleanup.
+No critical or warning issues detected.
+The implementation follows existing patterns well.

+# Designer Review
+
+## Domain Findings
+
+Typography hierarchy uses Inter for body and Fira Code for monospace. Heading hierarchy clear.
+The heading styles are well-defined with consistent sizing and spacing across the application.
+
+Dark/light theme: prefers-color-scheme respected, toggle in header. Color tokens via CSS custom properties.
+All surfaces and text adapt correctly to both modes. No hardcoded hex values found.
+
+Navigation sidebar with active state indicator, collapses on mobile. Structured nav with sections.
+The navigation tree depth is appropriate and the collapse animation is smooth.
+
+Responsive layout tested at 320px, 768px, 1024px, 1440px. No horizontal scroll at any viewport/breakpoint.
+Grid system adapts cleanly between breakpoints. Touch targets are appropriately sized on mobile.
+
+Code blocks use Shiki for syntax highlighting with copy button. Theme-consistent colors.
+The syntax theme follows the app's color palette. Line numbers are present and aligned.
+
+Tables have striped rows, hover effect, proper cell padding. Horizontal scroll on mobile.
+The table header is sticky on long tables. Sort indicators are visible and functional.
+
+Loading states: skeleton screens on all async operations, spinner for form submissions.
+The skeleton shimmer animation matches the brand colors. No blank flashes during transitions.
+
+Error states: error boundary with retry action. 404 page with navigation back.
+Error messages are human-readable and provide context-specific recovery suggestions.
+
+Favicon and meta tags: custom favicon, og:image, title and description set.
+The favicon renders well at both 16x16 and 32x32. Social preview image looks professional.
+
+Focus-visible styles: custom focus ring on all interactive elements. Keyboard navigation logical.
+Tab order follows visual layout. Focus ring contrast ratio meets WCAG AA requirements.
+
+Page transitions: smooth fade between views — not hard cuts.
+Transition duration is consistent at 200ms. No content flash during view changes.
+
+TESTING.md present with feature inventory, setup instructions, and cleanup steps.
+Testing documentation covers all major user flows with step-by-step reproduction instructions.
+
+## Summary
+All quality baseline items verified. The product meets polished tier requirements across all categories.
+Design implementation is consistent with the specification and brand guidelines.
+No critical or warning-level issues found. Product is ready for acceptance testing.
+The visual hierarchy guides the user's eye through the content naturally.
+Interaction patterns are consistent and predictable across all views.

+
+## Detailed Module Review
+
+The authentication module correctly validates JWT tokens and refreshes expired sessions.
+The database layer uses connection pooling with configurable pool sizes per environment.
+The API routes follow RESTful conventions with consistent error response shapes.
+Middleware ordering is correct — auth before validation before handler.
+The caching layer uses appropriate TTLs and invalidation strategies.
+Rate limiting is configured per-endpoint based on sensitivity.
+The logging middleware captures request IDs for distributed tracing.
+CORS configuration is locked down to known origins.
+Static asset serving includes proper cache headers.
+Health check endpoint reports dependency status accurately.
+The graceful shutdown handler drains connections before exit.
+Environment variable validation happens at startup, not lazily.
+The test helpers provide clean database state between test runs.
+Mock factories generate realistic test data with proper relationships.

+# Engineering Review
+
+## Analysis
+
+The code has been reviewed for correctness, performance, and maintainability.
+All functions are well-tested with appropriate unit test coverage.
+Error handling follows the established project patterns consistently.
+The implementation satisfies the acceptance criteria in the task specification.
+No security vulnerabilities found in the changed code paths.
+Dependencies are current and have no known CVE advisories.
+Build and lint pass without warnings or errors.
+The module boundaries are clean with well-defined interfaces.
+Type definitions provide good IDE support and catch common errors.
+Configuration is externalized and environment-specific values are not hardcoded.
+Logging output is appropriate for production debugging needs.
+The API contract is backward compatible with previous versions.
+Database migrations are idempotent and can be safely re-run.
+The implementation follows SOLID principles throughout.
+Code documentation covers public APIs and non-obvious implementation details.
+Performance characteristics are suitable for the expected workload.
+The test suite includes both positive and negative test cases.
+Edge cases are handled gracefully with appropriate error messages.
+The CI pipeline validates all quality gates before merge.
+No dead code or unused imports in the changed files.
+The changes are appropriately scoped — one logical change per commit.
+Inter-module dependencies are minimal and well-documented.
+Concurrency handling is correct for the shared resources used.
+The error recovery path has been tested manually.
+Resource cleanup happens correctly in all code paths.
+
+## Infrastructure Verification
+
+The Docker configuration builds successfully with no cache invalidation issues.
+The Kubernetes manifests pass schema validation for the target cluster version.
+Health check probes have appropriate timeouts and failure thresholds.
+The service mesh configuration routes traffic correctly between versions.
+Secrets management uses the approved vault integration pattern.
+The monitoring dashboard has panels for all key business metrics.
+Alert thresholds are set based on historical P95 values with adequate headroom.
+The rollback procedure has been tested in staging successfully.
+The deployment pipeline includes automated smoke tests post-deploy.
+Blue-green deployment configuration allows zero-downtime releases.
+The autoscaling policy is based on CPU and memory utilization.
+Database connection pooling is configured for the expected concurrent load.
+The CDN cache invalidation strategy covers all affected asset paths.
+Log aggregation captures structured JSON with correlation IDs.
+The backup schedule meets the RPO requirement for this service tier.

+## 7. Mechanical Enforcement (Loop)
+
+Three enforcement mechanisms operate at the harness level — no LLM judgment, pure code.
+
+### Summary Lint (hard error)
+
+`complete-tick` rejects (`completed: false`) the final tick if `--description` contains deferral language: `deferred`, `next loop`, `future work`, `follow-up loop`, `punted`, `later loop`, `TODO: next`.
+
+**Negation allowlist:** phrases like `not deferred`, `no deferral`, `nothing deferred` bypass the check.
+
+**Scope:** Only fires on the final tick (`next_unit === null`). Mid-pipeline ticks are unaffected.
+
+### Drain Gate (hard block)
+
+`next-tick` blocks termination (`terminate: false, drain_required: true`) when `backlog.md` has open items (`- [ ]`). Returns actionable items (those with 🔴 or 🟡) in the response.
+
+**Escape hatches:**
+- `--force-terminate` flag bypasses the drain gate
+- `_drain_completed: true` in loop-state.json bypasses it (set by orchestrator after drain cycle)
+
+### Plan Lint (warnings)
+
+`init-loop` warns (does not block) when:
+- Plan has implement/build units but **zero** test/e2e/accept units
+- Plan has test units but the **implement:test ratio ≥ 3:1** (e.g., 6 implements, 1 e2e)
+- Implement/build units lack `verify:` sub-lines
+- Review/accept units lack `eval:` sub-lines

+The CLI does **not** scan project-local `.opc/runbooks/` automatically

+harness invocation). Saving generated plans back to disk is a manual
+step today — see `docs/runbooks.md` for the full schema and the

+**If runbook found (matchRunbook returns a match):**
+1. Use the best-matching runbook's `units:` list as the plan
+2. Use its `flow:` as the per-unit flow template (overrides auto-detection)
+3. Use its `tier:` as the quality tier (if set)

+- `/opc loop --no-runbook <task>` is *planned* CLI sugar that would
+  set the env var for one invocation. **Not yet wired into `/opc loop`
+  arg parsing as of v0.8** — until it lands, set the env var directly.
+
 **If no runbook found:**
 1. Proceed to Step 1 (Plan Decomposition) as normal

+2. (Optional) After decomposition, suggest the user save the generated
+   plan to `~/.opc/runbooks/{task-slug}.md` for reuse. There is no
+   auto-write step — the orchestrator only emits the suggestion.
 
 ## Procedure
 
+### Step 0 — Runbook Lookup (before decomposition)
+
+Before Step 1, shell out to:
+
+```bash
+opc-harness runbook match "<task phrase>" [--dir <runbook-dir>]
+```
+
+- Exit `0` + `matched: true` → **skip Step 1**. Adopt the returned
+  runbook's `units`, `flow`, `tier`, `protocolRefs` as the plan. Write
+  them into `$SESSION_DIR/plan.md` with a header noting which runbook fired
+  and the score.
+- Exit `3` (match-miss) → proceed to Step 1.
+- To force a miss without scanning disk, prepend `OPC_DISABLE_RUNBOOKS=1`
+  to the command. The CLI returns exit 3 with `disabled: true` in the
+  payload. (Once `/opc loop --no-runbook` ships in CLI parsing, it will
+  set this env var for you.)
+
+Rationale: matching is cheap (O(#runbooks × #patterns)), and a reused
+plan avoids a full LLM decompose round. See `docs/runbooks.md` for the
+schema and `examples/runbooks/add-feature.md` for a canonical seed.

+1. **Cite evidence, not opinions.** Every finding must reference a specific `file:line` or paste the exact code/output that demonstrates the issue. "This could be a problem" without evidence = auto-flagged as `noCodeRefs`.
+2. **Address anomalies.** If execution output contains errors, warnings, stack traces, or unexpected behavior — you must address them explicitly. Do not skip inconvenient signals because the happy path works.
+3. **No aspirational claims.** Do not write "implementation looks correct" or "code appears well-structured" without tracing the actual logic path. Hollow praise triggers `lowUniqueContent` and `lineLengthVarianceLow` detection.
+4. **Distinguish root cause from symptom.** When reporting issues, trace to the structural cause. "Button doesn't work" is a symptom; "onClick handler references undefined state variable at `Component.tsx:47`" is a root cause.
+5. **Cover the change scope.** Your review must touch ALL files/areas that were changed, not just the first file you opened. Partial coverage triggers `findingDensityLow` when your line count is high but finding count is low relative to change scope.

+## What's Different in v0.8
+
+**Compound eval quality gate (D2).** 11-layer substance check on every eval — thin content, missing code refs, low uniqueness, fabricated references, aspirational claims, change scope coverage, etc. ≥3 layers tripped → hard FAIL (enforce by default); `--no-strict` downgrades to shadow mode. thinEval substance exemption: short evals with complete reasoning/fix/refs are exempt. Evaluator guidance: when D2 triggers, `evaluatorGuidance` output tells the evaluator exactly which layers failed and how to fix.
+
+**Iteration escalation (D3).** Persistent eval warnings across ≥2 iterations auto-escalate to FAIL. No more infinite loops of shallow reviews.
+
+**Task Scope Registry.** Loop mode plans require `## Task Scope` with SCOPE-N items. The harness validates at init and blocks completion if any scope item is uncovered — preventing the #1 failure mode where LLM decomposition silently drops requirements.
+
+**Pipeline E2E lint.** Tasks containing pipeline keywords (cron, webhook, CI/CD) must have an e2e-live-trigger acceptance criterion. Proxy evidence (unit tests) ≠ live evidence.
+
+**Evaluator prompt hardening (D6).** 5 evidence standards baked into the evaluator protocol: cite evidence, address anomalies, no aspirational claims, distinguish root cause vs symptom, cover change scope.

+## Extensions
+
+OPC has a capability-routed extension surface. Extensions live in
+`~/.claude/skills/opc-extension/<name>/` — each with `ext.json` (capability
+declarations) + `hook.mjs` exporting any of `promptAppend` / `verdictAppend`
+/ `executeRun` / `artifactEmit` hooks. No fork, no rebuild. Hooks are
+sandboxed via per-extension timeouts + circuit breakers, so a broken
+third-party extension can't take down the harness.
+
+The companion repo **[opc-extensions](https://github.com/iamtouchskyer/opc-extensions)** ships 4 extensions: `design-intelligence` (theme injection + design coverage + VLM visual eval), `git-changeset-review`, `memex-recall`, and `session-logex`.

+## Reproducing benchmarks
+
+OPC ships with an extension system (v0.5, Run 1) so you can plug in additional hooks — visual checks, design-system audits, a11y scans — without forking the skill. The extension loader honors three bypasses so a single harness invocation can ignore locally-configured extensions:
+
+```bash
+# Disable every extension for one harness run
+OPC_DISABLE_EXTENSIONS=1 node bin/opc-harness.mjs init --flow review --entry review --dir .harness
+
+# Same effect, CLI flag form
+node bin/opc-harness.mjs init --flow review --entry review --dir .harness --no-extensions
+
+# Whitelist specific extensions only
+node bin/opc-harness.mjs init --flow review --entry review --dir .harness --extensions visual-check,a11y
+```
+
+Priority order: `OPC_DISABLE_EXTENSIONS=1` env var > `--no-extensions` CLI flag > `--extensions foo,bar` whitelist > config in `~/.claude/skills/opc-extension/config.json`. See `docs/specs/2026-04-16-opc-extension-system-design.md` for the full contract.
+
+**Note:** `bash test/run-all.sh` runs OPC's own internal test suite, which includes tests that intentionally *load* extensions to exercise the system. Don't set `OPC_DISABLE_EXTENSIONS=1` when running the suite — use the bypasses only on real benchmarking / workflow invocations.

+
+In loop mode, every `plan.md` MUST include a `## Task Scope` section listing the user's original requirements:

+## Task Scope
+- SCOPE-1: Backend API for user auth
+- SCOPE-2: Frontend login page with form validation
+- SCOPE-3: Browser E2E tests covering login flow
+- SCOPE-4: Unit tests with 100% coverage on new code
+```
+
+The harness enforces this mechanically:
+- **init-loop** refuses to start if `## Task Scope` is missing (bypass: `--skip-scope`)
+- **complete-tick** on the final tick checks that every SCOPE-N item was covered by at least one completed unit (keyword overlap or explicit reference). Uncovered items = hard error, pipeline cannot complete (bypass: `--skip-scope-check`)
+- **next-tick** termination output includes `uncovered_scope` if any items lack coverage
+
+This prevents the #1 failure mode: LLM decomposition misses part of the original task, pipeline declares "complete" while major scope items are untouched.

-The codebase follows a clean layered architecture with clear separation of concerns.
-Models are well-defined with proper TypeScript types.
-Services abstract business logic from route handlers.
-
-## Findings
-
-🔵 src/main.ts:10 — Import ordering inconsistent
-→ Group external imports before internal ones
-Reasoning: Following the project's established convention in other files.
-
-🔵 src/utils.ts:25 — Unused helper function
-→ Remove `formatDate` — it's not called anywhere
-Reasoning: Dead code increases maintenance burden.
-
-🔵 src/db.ts:42 — Connection pool size hardcoded
-→ Move to environment variable
-Reasoning: Production environments may need different pool sizes.
-
-## Security
-No SQL injection vectors found. Input validation is proper.
-Authentication middleware is correctly applied to protected routes.
-CORS settings are appropriately restrictive.
-
-## Performance
-Database queries use proper indexing.
-No N+1 query patterns detected.
-Response caching is applied where appropriate.
-
-## Error Handling
-All async routes have try-catch blocks.
-Error responses include proper status codes and messages.
-Validation errors are distinguished from server errors.
-
-## Testing
-Unit test coverage appears adequate for core business logic.
-Integration tests cover the critical user flows.
-Missing edge case tests for concurrent operations.
-
-## Summary
-Overall code quality is good. Three minor suggestions found.
-No critical or warning issues detected.
-The implementation follows existing patterns well.

-# Thorough Code Review
-
-## Architecture Analysis
-The codebase follows a well-structured MVC pattern.
-Dependency injection is used consistently.
-Module boundaries are clearly defined with explicit exports.
-
-## Security Assessment
-No SQL injection vectors found in database queries.
-Authentication middleware properly validates JWT tokens.
-CORS is configured to allow only approved origins.
-Input sanitization covers all user-facing endpoints.
-
-## Findings
-
-🔵 src/main.ts:10 — Import ordering inconsistent with project convention
-→ Group external imports before internal ones, alphabetize within groups
-Reasoning: Following the project's established convention seen in other files.
-
-🔵 src/utils.ts:25 — Unused helper function `formatDate` is dead code
-→ Remove `formatDate` — it's not called anywhere in the codebase
-Reasoning: Dead code increases maintenance burden and confuses new developers.
-
-🟡 src/auth.ts:42 — Token refresh window is too narrow (30s)
-→ Increase refresh window to 300s to prevent auth races
-Reasoning: Users with slow connections may lose their session during the refresh gap.
-
-🔵 src/db.ts:88 — Connection pool size hardcoded to 10
-→ Move to DATABASE_POOL_SIZE environment variable with default 10
-Reasoning: Production environments with higher traffic need larger pool sizes.
-
-## Performance Review
-Database queries use proper indexing on frequently queried columns.
-No N+1 query patterns detected in the ORM usage.
-Response caching is applied to read-heavy endpoints.
-Bundle splitting is configured for optimal loading.
-
-## Testing Assessment
-Unit test coverage is 85% for core business logic modules.
-Integration tests cover the four critical user flows.
-E2E tests verify the login-to-checkout journey end-to-end.
-Edge cases for concurrent operations need additional coverage.
-
-## Summary
-Found 4 issues: 1 warning (auth token refresh), 3 suggestions.
-Overall code quality is strong. The auth issue should be addressed
-before the next release to prevent user session drops.

-
-## Context
-Reviewed the stylesheet for maintainability and consistency.
-Checked naming conventions, variable usage, and selector specificity.
-The codebase uses a mix of modules with varying maturity levels.
-Primary focus: tokens, layout, responsive behavior, and animation timing.
-Secondary focus: specificity, inheritance, and cascade interactions.
-
-## Methodology
-Walked through the stylesheet file by file noting patterns.
-Each section was examined for repetition that could be abstracted.
-Color values and spacing units received particular attention.
-Browser prefix coverage was cross-checked against caniuse data.
-Animation easing curves were verified against the design tokens.
-
-## Findings
-
-🔵 Consider using CSS variables — style.css:5 — hex color #3366cc appears 7 times
-→ Extract to --color-primary custom property declared at :root
-Reasoning: Centralizing color definitions makes theme updates trivial and prevents drift across components.
-
-## Positive Observations
-The selector specificity is generally well-controlled throughout the file.
-No !important declarations were found outside the reset block.
-Media queries are consistently ordered mobile-first with logical breakpoints.
-Animation durations use a reasonable set of values (100ms, 200ms, 400ms).
-Z-index values are clustered in recognizable ranges by layer role.
-Font stack declarations include appropriate fallbacks for all major platforms.
-Focus styles are present on every interactive element.
-Hover states respect the prefers-reduced-motion media query.
-
-## Areas Reviewed
-Color and typography tokens were audited against the design system.
-Layout and spacing systems use a consistent 4px base unit throughout.
-Component class naming follows a BEM-inspired convention reliably.
-Responsive breakpoint usage is consistent across pages and components.
-Animation and transition timing matches the documented motion tokens.
-Browser prefix coverage is appropriate for the stated support matrix.
-Custom scrollbar styles are gated behind feature detection.
-Print stylesheet is minimal but covers the critical reset cases.
-
-## Conclusion
-The stylesheet is in good shape overall and ready for the next release cycle.
-One minor optimization suggestion was noted above in the findings section.
-No blocking issues were identified during this pass of the codebase.
-The team has clearly invested in CSS architecture and it shows in the quality.

-# Security Review
-
-## Scope
-Reviewed authentication, authorization, input validation, and data storage.
-Scanned for OWASP Top 10 categories with a focus on injection and broken access control.
-Verified session and token lifecycle end-to-end for the critical user journeys.
-
-## Methodology
-Walked through each request handler end-to-end from entry to response.
-Cross-referenced with the existing security headers configuration file.
-Verified that secrets do not appear in logs or error messages on any path.
-Ran a static analysis sweep focused on taint sources and sinks in handlers.
-Checked that all outbound HTTP calls validate the target host before dispatch.
-
-## Areas Reviewed
-Session management and token handling across all authenticated endpoints.
-SQL query construction and parameterization in the data access layer.
-User input sanitization on all public-facing and internal-public endpoints.
-File upload handling, MIME validation, and storage path containment.
-Rate limiting configuration on authentication and password-reset endpoints.
-Outbound request validation to prevent server-side request forgery attacks.
-Cookie attributes including Secure, HttpOnly, SameSite, and Domain scope.
-Content Security Policy headers and their effective directives.
-
-## Positive Observations
-Password hashing uses a modern algorithm with appropriate cost factor.
-JWT tokens are signed with an asymmetric key and include sensible expiration.
-All database queries use parameterized statements via the ORM layer.
-CORS is configured narrowly to the known production and staging origins.
-Secrets are loaded from environment variables and are never logged.
-Security headers are applied consistently via middleware on every response.
-Error responses avoid leaking stack traces or internal identifiers.
-Session invalidation on logout clears both server and client state.
-
-## Cross-Cutting Concerns
-The team maintains a security posture document updated each release.
-Dependency scanning runs in CI and blocks merges on critical advisories.
-Penetration test findings from the last engagement have all been resolved.
-A threat model exists for the authentication subsystem and is current.
-
-## No Findings
-No critical, warning, or suggestion-level issues were found during this pass.
-The codebase demonstrates mature security hygiene across all surfaces reviewed.
-No follow-up actions are required from this review cycle at this time.
-
-## Summary
-The security review concluded without identifying any defects.
-The combination of architectural discipline and tooling investment shows.
-Recommendation is to proceed to the next stage of the release process.
-Continue current practices for dependency hygiene and CI security gates.
-A follow-up review of the new microservice is scheduled for next sprint.

-# Security Review
-## Summary
-Reviewed the authentication flow for common vulnerabilities.
-Checked for SQL injection, XSS, CSRF, and session fixation issues.
-
-## Findings
-🔵 suggestion — auth.js:42 — prefer const for immutable bindings
-→ Change `let user = ...` to `const user = ...`
-Reasoning: const signals immutability and enables compile-time checks.
-
-## Conclusion
-No critical security issues found. One style suggestion only.
-EVAL
-    cat > "$dir/nodes/$node/run_1/eval-performance.md" << 'EVAL'
-# Performance Review
-## Approach
-Profiled the hot path under typical load. Reviewed algorithmic complexity.
-Measured allocation patterns and database query counts.
-
-## Findings
-🔵 suggestion — handler.js:20 — cache the result of expensive computation
-→ Wrap the function in a memoize helper
-Reasoning: The same input is queried many times per request cycle.
-
-## Conclusion
-No performance regressions. One optimization opportunity noted.

-# Thorough Code Review
-
-## Architecture
-The codebase follows a clean layered architecture with clear separation of concerns.
-
-## Findings
-
-🔵 src/main.ts:10 — Import ordering inconsistent
-→ Group external imports before internal ones
-Reasoning: Following the project's established convention in other files.
-
-🔵 src/utils.ts:25 — Unused helper function
-→ Remove `formatDate` — it's not called anywhere
-Reasoning: Dead code increases maintenance burden.
-
-🔵 src/db.ts:42 — Connection pool size hardcoded
-→ Move to environment variable
-Reasoning: Production environments may need different pool sizes.
-
-## Summary
-
-Overall code quality is good. Three minor suggestions found, all style/cleanup.
-No critical or warning issues detected.
-The implementation follows existing patterns well.

-# Designer Review
-
-## Domain Findings
-
-Typography hierarchy uses Inter for body and Fira Code for monospace. Heading hierarchy clear.
-The heading styles are well-defined with consistent sizing and spacing across the application.
-
-Dark/light theme: prefers-color-scheme respected, toggle in header. Color tokens via CSS custom properties.
-All surfaces and text adapt correctly to both modes. No hardcoded hex values found.
-
-Navigation sidebar with active state indicator, collapses on mobile. Structured nav with sections.
-The navigation tree depth is appropriate and the collapse animation is smooth.
-
-Responsive layout tested at 320px, 768px, 1024px, 1440px. No horizontal scroll at any viewport/breakpoint.
-Grid system adapts cleanly between breakpoints. Touch targets are appropriately sized on mobile.
-
-Code blocks use Shiki for syntax highlighting with copy button. Theme-consistent colors.
-The syntax theme follows the app's color palette. Line numbers are present and aligned.
-
-Tables have striped rows, hover effect, proper cell padding. Horizontal scroll on mobile.
-The table header is sticky on long tables. Sort indicators are visible and functional.
