+# CodeFlow Agent Contract
+
+This file is the default engineering contract for CodeFlow. Agents and humans should treat these rules as the baseline for every change.
+
+## Core Rules
+
+1. Reuse before adding.
+Search for existing hooks, helpers, schemas, route utilities, and UI primitives before creating new abstractions.
+
+2. Do not duplicate business logic.
+Shared behavior must live in extracted utilities, hooks, or services. Do not copy logic between `blueprint-workbench`, `policy-workbench`, routes, or store helpers.
+
+3. Do not reinvent the wheel.
+Prefer stable platform APIs or maintained libraries when the problem is not product-specific.
+
+4. No silent failures.
+Every catch path must either:
+- return a structured error,
+- set a visible UI error or stale state, or
+- log diagnostic context intentionally.
+
+5. Be truthful about feature maturity.
+Heuristic, simulated, AI-generated, or scaffold output must be labeled as such in APIs and UI. Do not present them as observed truth or production-ready implementation unless validated.
+
+6. Validate external I/O.
+All request bodies, persisted payloads, AI responses, MCP responses, and export manifests must be schema-validated before use.
+
+7. Validate generated code.
+AI-generated implementation is not production truth by default. Prefer local validation before marking code as implemented or runnable.
+
+8. Do not persist raw secrets in browser storage.
+Use server environment variables, session-only memory, or explicit secure local handling. Never store raw secrets in exported artifacts, sessions, or long-lived browser storage.
+
+9. Tests are part of the change.
+New route, runtime, export, or advanced feature work should include direct coverage for the changed path.
+
+10. Do not keep growing giant files.
+When touching oversized files, prefer extracting helpers or section-specific components instead of adding more inline logic.
+
+## Execution And Validation Contract
+
+11. Make every code-bearing node independently verifiable.
+Function, API, and class nodes must compile and run directly or explicitly declare why they are not directly runnable. Module nodes must aggregate child results instead of hiding failures.
+
+12. Green means observed pass, not optimism.
+Graph edges or nodes may turn green only from real compile, execution, and assertion evidence. Simulated, heuristic, scaffold, skipped, or manually assumed states must never use the same success semantics.
+
+13. A pass must be contract-true.
+A node run only passes when all of these hold:
+- the artifact compiles,
+- the input shape is validated,
+- the callable returns the expected output shape or side effect,
+- downstream handoff data is validated before it is consumed.
+
+14. Whole-graph runs must preserve failure locality.
+When a full flow runs, the system must record which exact node, method, or function failed, what input it received, what output or error it produced, and which downstream edge was blocked.
+
+15. Composite nodes must support drill-down.
+If a module or class is shown as failed, the UI and persisted execution data must allow a user to drill into the exact child method or function that failed. A parent node may not be shown as healthy when a child execution failed.
+
+16. Warnings are not cosmetic.
+Do not paper over compiler warnings, type errors, build warnings, test flake, or security findings. Fix them, gate on them, or document an explicit accepted-risk decision with scope and owner.
+
+## Test And Review Discipline
+
+17. Every code-bearing function needs direct tests.
+Each function or class method added or materially changed should have success-path, failure-path, and edge-case coverage unless the repo already has stronger integration coverage that makes the direct test redundant.
+
+18. Modules and flows need integration coverage.
+Module-level behavior, API routes, and graph execution flows must have integration tests that exercise real boundaries and real data handoffs.
+
+19. No fake-pass tests.
+The following are not acceptable as sufficient proof on their own:
+- tests that only assert mocks were called,
+- snapshot-only tests for business logic,
+- tests with no meaningful assertions,
+- widening expectations just to make CI pass,
+- disabling warnings or validations without a documented reason.
+
+20. Prefer fail-to-pass before pass-to-pass.
+When fixing a bug or regression, add or tighten a test that fails first, then make it pass, then keep surrounding pass-to-pass coverage green.
+
+21. Review behavior, not just output.
+Passing tests are necessary but not sufficient. Check contracts, warnings, error handling, security boundaries, dependency choices, and code duplication before calling work done.
+
+22. No handwaving.
+Claims such as "fixed", "safe", "production-ready", or "green" must be backed by specific evidence: compile output, test coverage, runtime validation, warning status, and file-level changes.
+
+## AI-Assisted Engineering Risks
+
+23. Treat model output as untrusted input.
+AI output must be schema-validated, compiled, tested, and reviewed before it is treated as implementation, command input, configuration, or persisted state.
+
+24. Guard against hallucinated dependencies and APIs.
+Before adding a package, method, endpoint, or config flag suggested by AI, verify that it exists, is maintained, fits the repo, and is already available or intentionally approved.
+
+25. Guard against prompt injection and tool poisoning.
+Do not let prompts, MCP tool descriptions, retrieved documents, or generated code silently change system authority. Keep least privilege, validate tool metadata, and keep security-critical policy in code.
+
+26. Do not confuse benchmark pass rates with production quality.
+A model can pass tests and still introduce bugs, vulnerabilities, code smells, or architecture drift. Static analysis, contract checks, and human review remain mandatory.
+
+27. Reuse proven patterns before asking AI to invent new ones.
+When solving a problem, first point the model at the existing house style, neighboring modules, and established abstractions. Do not accept novelty when the repo already has a correct pattern.
+
+## CodeFlow Defaults
+
+- Deployment model: single-user, local-first workstation.
+- Localhost MCP servers are allowed, but must still use explicit validation and timeout handling.
+- Generated code is only production-grade when validated; scaffold output must be marked clearly.
+- Digital Twin simulation must never be presented as live observed traffic.
+- Refactor/heal currently means graph drift repair unless a change explicitly modifies real source code.
+- Release gates are `npm run lint`, `npm run check`, `npm test`, and `npm run build`.
+- Required target runtime semantics are documented in `docs/execution-validation-contract.md`.
+- AI-assisted coding failure modes and required countermeasures are documented in `docs/ai-coding-risk-playbook.md`.

+# CodeFlow IDE Integration Plan
+
+This file only tracks remaining work. Existing repo pieces such as the current Monaco wrapper, file APIs, file tree, file tabs shell, and graph-side feature panels are intentionally omitted as completed foundations.
+
+The remaining goal is not "add Monaco somewhere". The goal is to make IDE mode a full CodeFlow surface with Monaco as the primary editing window while keeping the graph live and fully connected.
+
+## Required IDE Layout
+
+When IDE mode is active, the layout must be:
+- Left sidebar: file explorer, VS Code-like in behavior, opening files into Monaco tabs.
+- Main area with no file open: full graph view, same as today's main CodeFlow experience.
+- Main area with a file open: Monaco becomes the primary surface.
+- Floating graph panel in the bottom-right when Monaco is open:
+  - default size about `30%` width and `35%` height
+  - draggable
+  - resizable
+  - large enough to read node names and see edges/status
+- Right sidebar: reserved panel slot for the future agent window. Do not build the agent itself yet, but the slot must exist in the layout.
+
+## Non-Negotiable Behavior
+
+- The graph-first workbench remains the default mode.
+- IDE mode is not a reduced shell. It must carry the same live CodeFlow state.
+- The minimized graph must stay live with heatmap, VCR, trace overlays, execution highlights, and node status updates.
+- Clicking a node in the minimized graph must open the matching file in Monaco and scroll to the exact source location for that node.
+- Graph state in graph mode and IDE mode must be the same shared Zustand state, not separate copies.
+- Existing CodeFlow capabilities must be integrated into IDE mode, not merely left available in graph mode.
+
+## Remaining Work
+
+### P1. IDE State, Mode, And Layout
+- Extend `src/store/blueprint-store.ts` instead of creating a parallel IDE store.
+- Finish migrating graph ownership needed for IDE mode so graph mode and IDE mode read/write the same shared state instead of separate local copies.
+- Move `repoPath` into shared app state so Monaco, graph navigation, and file APIs all point at the same repository root.
+- Add `mode: "graph" | "ide"` plus floating graph panel state.
+- Keep graph-first as the default mode.
+- Use the app's existing file tree for the VS Code-like explorer surface; `@monaco-editor/react` does not provide a built-in explorer UI.
+- In IDE mode:
+  - left sidebar stays the file explorer
+  - main area shows full graph when no file is open
+  - main area switches to Monaco when a file is open
+  - graph becomes a live floating panel at roughly `30% x 35%`
+  - right sidebar is an empty reserved slot for the future agent window
+- Create `src/components/ide-layout.tsx` to own this layout.
+- Add a draggable/resizable floating graph panel with `react-rnd`.
+- Persist layout state through the existing browser storage helpers in `src/lib/browser/storage.ts`.
+
+### P2. Repo-Scoped File APIs And Explorer Flow
+- Update `src/app/api/files/list/route.ts`, `src/app/api/files/get/route.ts`, and `src/app/api/files/post/route.ts` to resolve paths from the active project/session `repoPath`, not `process.cwd()` or a global env default.
+- Keep the file API security boundary strict: reads and writes must stay inside the active repo root.
+- Start from `src/components/file-tabs.tsx`; do not rebuild tabs or the file tree from scratch.
+- Fix file loading to match the current `/api/files/get` route contract.
+- Add dirty indicators for modified files.
+- Add save wiring through the existing `/api/files/post` route.
+- Keep open/close/switch behavior in `src/store/blueprint-store.ts`.
+
+### P3. Monaco Setup And Editor Behavior
+- Keep Monaco lazy-loaded via `next/dynamic(..., { ssr: false })`.
+- Add `beforeMount` Monaco initialization so worker configuration happens before editor startup.
+- Configure Monaco TypeScript/JavaScript workers so they do not conflict with the app runtime.
+- Make dark theme the default editor theme and align it with the existing CodeFlow UI theme.
+- Keep `src/components/code-editor.tsx` focused on the Monaco wrapper rather than tab management.
+- Add `src/components/code-diff-editor.tsx` for refactor and drift review flows.
+
+### P4. Graph To Editor Navigation
+- Add exact source location metadata to blueprint nodes in `src/lib/blueprint/schema.ts`.
+- Populate that metadata during repo analysis in `src/lib/blueprint/repo.ts` using ts-morph source positions.
+- Create `src/lib/blueprint/node-navigation.ts`.
+- Wire graph selection to:
+  - open the correct file
+  - activate the correct tab
+  - scroll Monaco to the exact function/class start line
+  - highlight the relevant line or range
+- Surface missing navigation metadata explicitly instead of failing silently.
+
+### P5. Editor Intelligence
+- Keep the existing Monaco integration, but upgrade editor intelligence so repo-aware TypeScript data comes from the analyzed codebase rather than only the current AI completion path.
+- Use the existing ts-morph workspace/context to improve symbol-aware completions and navigation fidelity.
+- Preserve the current completion feature where useful, but do not treat the current AI-only completion path as sufficient for the prompt requirement.
+
+### P6. Workbench IDE Mode Integration
+- Add IDE mode rendering to `src/components/blueprint-workbench.tsx`.
+- Add a Graph / IDE mode toggle in the toolbar.
+- Add `Cmd/Ctrl+Shift+E` as the mode-switch shortcut.
+- Preserve graph and IDE panel state across mode switches.
+- Ensure the minimized graph is the same live graph state, not a duplicate copy.
+
+### P7. Full CodeFlow Feature Parity Inside IDE Mode
+- IDE mode must expose the same CodeFlow capabilities that currently exist in the graph-first workbench.
+- Reuse existing workbench logic; do not reimplement feature backends.
+- Integrate these existing features into IDE mode UI and flows:
+  - VCR / replay
+  - heatmap / observability
+  - digital twin
+  - refactor / drift
+  - branches / diff
+  - MCP
+  - ghost nodes
+  - execution status and run feedback
+  - export / approval
+  - settings and editor-related controls
+  - cat mascot / brand elements where already present
+- Ensure those signals still update in the minimized graph while Monaco is open.
+- Ensure node activity in those flows still lights up the minimized graph in IDE mode.
+- Ensure refactor / drift and branch comparison use Monaco diff view where appropriate.
+- The right sidebar and IDE toolbar/status areas should become the integration surfaces for these features instead of leaving them graph-mode-only.
+- Acceptance bar: a developer should not have to leave IDE mode to use core CodeFlow capabilities.
+
+### P8. Optional Large-File Follow-Up
+- `/api/files/get` already streams large files.
+- Only add range or partial-read support if IDE profiling shows the current route is insufficient.
+
+## Acceptance Criteria
+
+- Graph mode remains the default unchanged workbench.
+- IDE mode matches the required layout above.
+- Opening a file moves Monaco into the main area and keeps a live floating graph visible.
+- Clicking any graph node opens the correct file and jumps to the correct line or range.
+- Core CodeFlow features remain usable in IDE mode without switching back to graph mode.
+- Drift and diff flows use Monaco diff editor instead of plain text diff output where applicable.
+
+## Dependencies To Add

+{
+  "react-rnd": "^10.4.13"
+}
+```

+  //   1. Resolve selector to an element.
+  //   2. Retry the following steps until the element is detached or frame navigates away.
+  //     2a. Wait for the element to be stable (not moving), visible and enabled.
+  //     2b. Scroll element into view. Scrolling alternates between:
+  //         - Built-in protocol scrolling.
+  //         - Anchoring to the top/left, bottom/right and center/center.
+  //         This is to scroll elements from under sticky headers/footers.
+  //     2c. Click point is calculated, either based on explicitly specified position,
+  //         or some visible point of the element based on protocol content quads.
+  //     2d. Click point relative to page viewport is converted relative to the target iframe
+  //         for the next hit-point check.
+  //     2e. (injected) Hit target at the click point must be a descendant of the target element.
+  //         This prevents mis-clicking in edge cases like <iframe> overlaying the target.
+  //     2f. (injected) Events specific for click (or some other action type) are intercepted on
+  //         the Window with capture:true. See 2i for details.
+  //         Note: this step is skipped for drag&drop (see inline comments for the reason).
+  //     2g. Necessary keyboard modifiers are pressed.
+  //     2h. Click event is issued (mousemove + mousedown + mouseup).
+  //     2i. (injected) For each event, we check that hit target at the event point
+  //         is a descendant of the target element.
+  //         This guarantees no race between issuing the event and handling it in the page,
+  //         for example due to layout shift.
+  //         When hit target check fails, we block all future events in the page.
+  //     2j. Keyboard modifiers are restored.
+  //     2k. (injected) Event interceptor is removed.
+  //     2l. All navigations triggered between 2g-2k are awaited to be either committed or canceled.
+  //     2m. If failed, wait for increasing amount of time before the next retry.

+```
+
+## Exports
+
+```ts
+import { buildBlueprintGraph, analyzeTypeScriptRepo } from "@abhinav2203/codeflow-core/analyzer";
+import { exportBlueprintArtifacts } from "@abhinav2203/codeflow-core/export";
+import { detectGraphConflicts } from "@abhinav2203/codeflow-core/conflicts";
+import type { BlueprintGraph } from "@abhinav2203/codeflow-core/schema";
+```
+
+## Scope
+
+This package contains the reusable, Node-oriented blueprint logic extracted from CodeFlow:
+
+- repository analysis

+# CodeFlow Package Decomposition
+
+## Existing Packages
+
+| Package | npm name | Description |
+|---------|----------|-------------|
+| `codeflow-core` | `@abhinav2203/codeflow-core` | Framework-agnostic core: schema, ts-morph repo analysis, export, conflict detection |
+| `coderag` | `@abhinav2203/coderag` | Code retrieval & RAG: embeddings, indexing, retrieval, MCP server |
+
+**`coderag` also appears in the dependency graph:**
+```text
+coderag β†’ @abhinav2203/codeflow-core
+```
+
+### `codeflow-core` Source Files (not yet isolated β€” extracted from `src/lib/blueprint/`)
+
+```
+src/lib/blueprint/
+  - schema.ts                 ← BlueprintGraph, BlueprintNode, BlueprintEdge, all type definitions
+  - repo.ts
+  - repo.test.ts
+  - utils.ts                  ← slugify, createNodeId, mergeFields, dedupeEdges, toPosixPath, etc.
+  - store-paths.ts            ← getStoreRoot, sessionDirForProject, latestSessionPath, etc.
+  - export.ts
+  - export.test.ts
+```
+
+> **Note:** `codeflow-core` is the foundation. `schema.ts` defines the entire type system used by every other package. `repo.ts` uses ts-morph for TypeScript repo analysis. `export.ts` handles blueprint artifact export. These are extracted first before any other package work begins.
+
+## Proposed New Packages
+
+| Package | Description |
+|---------|-------------|
+| `codeflow-canvas` | React Flow visual graph editor, node editing, trace/heatmap overlay |
+| `codeflow-prd` | PRD markdown parser, workflow extraction, reverse mode (code β†’ blueprint) |
+| `codeflow-execution` | Execution runner, task planning, phases, VCR recording, runtime tests |
+| `codeflow-analysis` | Cycle detection, architecture smells, graph metrics, refactor/heal |
+| `codeflow-evolution` | Ghost nodes (AI-suggested components), genetic algorithm for architecture variants |
+| `codeflow-agent` | Unified AI agent: OpenCode server + NVIDIA NIM + per-node codegen + TS validation |
+| `codeflow-dtwin` | Digital twin simulation, active node highlighting from trace data |
+| `codeflow-versioning` | Blueprint branching, branch diff/compare |
+| `codeflow-mcp` | MCP server configuration and tool registry (stays separate β€” protocol interface for all packages) |
+| `codeflow-store` | Local session storage, project-scoped state, checkpointing |
+
+**Total: 11 packages (9 new + 2 existing)**
+
+> **Note:** `codeflow-ai`, `codeflow-codegen`, and `codeflow-opencode` have been merged into `codeflow-agent`. `codeflow-mcp` is kept separate because it is a protocol-level interface (stdin/stdout JSON-RPC) that should be reusable by all packages, not just the agent.
+
+---
+
+## Recommended Build Order
+
+### Phase 1 β€” Foundation (depends only on codeflow-core)
+
+| # | Package | Why first |
+|---|---------|-----------|
+| 1 | `codeflow-store` | Session storage, checkpoints, project isolation β€” depends on core, can ship immediately |
+| 2 | `codeflow-mcp` | MCP server config, tool registry β€” depends on core, can ship immediately |
+
+### Phase 2 β€” Schema Producers (depend only on codeflow-core schema)
+
+| # | Package | Why |
+|---|---------|-----|
+| 3 | `codeflow-versioning` | Branches + diff β€” produces/consumes graph metadata, minimal deps |
+| 4 | `codeflow-prd` | PRD parsing β†’ produces blueprint graph |
+| 5 | `codeflow-analysis` | Cycles, smells, metrics, refactor/heal β†’ analyze graph |
+
+### Phase 3 β€” Agent Layer (depend on core + schema producers)
+
+| # | Package | Why |
+|---|---------|-----|
+| 6 | `codeflow-execution` | Runner, task planning, phases, VCR β€” needs schema + analysis |
+| 7 | `codeflow-agent` | OpenCode server + NVIDIA NIM + codegen + TS validation β€” needs core + execution |
+
+### Phase 4 β€” High-Level (depend on multiple layers)
+
+| # | Package | Why |
+|---|---------|-----|
+| 8 | `codeflow-evolution` | Ghost nodes + genetic algo β€” needs agent (for LLM calls) |
+
+### Phase 5 β€” Top Layer (full stack)
+
+| # | Package | Why |
+|---|---------|-----|
+| 9 | `codeflow-canvas` | React Flow UI β€” needs schema + execution traces |
+| 10 | `codeflow-dtwin` | Digital twin simulation β€” needs execution + canvas |

+```
+
+> **Merged note:** `codeflow-agent` replaces `codeflow-ai`, `codeflow-codegen`, and `codeflow-opencode`. These three were merged because they are not independently useful β€” `codeflow-opencode` already does code generation (which `codeflow-codegen` would duplicate), and `codeflow-ai` is a thin NVIDIA NIM wrapper that feeds into the same codegen pipeline. `codeflow-mcp` is kept separate because it is a protocol interface (stdin/stdout JSON-RPC) that all packages can use, not just the agent.
+

+
+## Inter-Package Communication Architecture
+
+**Core principle: packages communicate only via npm package dependencies, never via direct code imports.**
+
+Every internal package dependency is declared as an `npm` dependency in `package.json` pointing to the published package name (`@abhinav2203/codeflow-<name>`). During development inside the monorepo, use `workspace:*` ranges (requires workspaces to be configured in the root `package.json`); a release tool (e.g. `npm publish` with changesets, or pnpm publish) must rewrite `workspace:*` to the actual published semver range before the package reaches consumers on npm. This means:
+
+- Each package is **independently installable** β€” `npm install @abhinav2203/codeflow-prd` also pulls in `@abhinav2203/codeflow-core` as a transitive dep
+- Each package is **independently versionable** β€” semver bumps happen per package
+- Each package is **independently deployable** β€” you can run `codeflow-prd` CLI without any other codeflow package source present (except its npm deps)
+- Integration testing (all packages working together end-to-end) is a **later phase** β€” for now, each package is tested only against its npm dependency surface

+### How to Import Between Packages
+
+**❌ WRONG β€” direct monorepo import:**
+```typescript
+import { buildBlueprintGraph } from "../../codeflow-core/src/analyzer/index.js";
+```
+
+**βœ… CORRECT β€” npm package import:**
+```typescript
+import { buildBlueprintGraph } from "@abhinav2203/codeflow-core/analyzer.js";
+```
+
+During development within the monorepo, use workspace ranges (npm/yarn/pnpm workspaces). **Prerequisite:** declare a `workspaces` field in the root `package.json` listing all package paths. A release tool (e.g. changesets + `npm publish`, or `pnpm publish`) must rewrite `workspace:*` to the actual published semver version before the package is pushed to npm.
+
+```json
+{
+  "dependencies": {
+    "@abhinav2203/codeflow-core": "workspace:*",
+    "@abhinav2203/codeflow-analysis": "workspace:*"
+  }
+}
+```
+
+Once published to npm, workspace ranges are replaced with the resolved published semver version.

+> **Why does `codeflow-agent` depend on `codeflow-store`?** Because agent **reasoning** (session context, tool-use history, generated artifacts, agent logs) needs to be persisted and replayable. Rather than inventing its own storage layer, `codeflow-agent` uses `codeflow-store` as its persistence backend. Reasoning is stored as structured session data in `codeflow-store`, enabling checkpointing and replay without a separate storage mechanism.

+## Unaccounted API Routes
+
+The following API routes exist in `src/app/api/` but are NOT assigned to any package in this decomposition. They may belong to an existing package, a future package, or may need to be reassigned:
+
+| Route | Likely Owner | Notes |
+|-------|-------------|-------|
+| `src/app/api/coderag/route.ts` | `coderag` (existing) | RAG embedding + retrieval |
+| `src/app/api/files/get/route.ts` | TBD | File retrieval |
+| `src/app/api/files/list/route.ts` | TBD | File listing |
+| `src/app/api/files/post/route.ts` | TBD | File upload |
+| `src/app/api/terminal/sessions/route.ts` | TBD | Terminal session management |
+| `src/app/api/terminal/sessions/[sessionId]/route.ts` | TBD | Individual terminal session |
+
+> **Action needed:** Assign these routes to appropriate packages before extraction begins. `coderag` is an existing package and should take its own route. The file and terminal routes may belong to `codeflow-store` or a new `codeflow-fs` package.
+
+---
+
+These files are used by multiple packages. They should be moved to `@abhinav2203/codeflow-core` (or a dedicated utility package) to avoid code duplication and logic drift. Each consuming package should import them as a normal package dependency rather than copying the source:
+
+| File | Move to | Used by |
+|-------|---------|---------|
+| `src/lib/blueprint/file-tree.ts` | `@abhinav2203/codeflow-core` | `codeflow-prd`, `codeflow-store` |

+## Isolation Testing Strategy
+
+Each package should be testable in isolation β€” no full monorepo, no Next.js app needed. The testing surface is a **CLI** exposed via each package's `bin` field, plus an **MCP server** where noted. Run the command β†’ assert on output/behavior β†’ that's the signal the package works.
+
+**General pattern for each package:**
+
+```json
+// package.json
+{
+  "bin": {
+    "codeflow-<name>": "./dist/bin/cli.js"
+  }
+}
+```
+
+---
+
+### `codeflow-store`
+
+**CLI surface:**
+
+```bash
+# Sessions
+codeflow-store session init <project-path>
+codeflow-store session list
+codeflow-store session current
+
+# Checkpoints
+codeflow-store checkpoint create <session-id> --message "before refactor"
+codeflow-store checkpoint list <session-id>
+codeflow-store checkpoint restore <checkpoint-id>
+
+# Approvals
+codeflow-store approval list
+codeflow-store approval approve <approval-id>
+codeflow-store approval reject <approval-id> --reason "..."
+
+# Risk
+codeflow-store risk assess <export-path>
+```
+
+**Isolation test:** Run against a temp project dir β†’ verify checkpoint files created in `~/.codeflow-store/` β†’ restore β†’ assert files match original state.
+
+**Success signal:** Checkpoint files exist at correct paths, approval state transitions correctly, risk assessment returns a score.
+
+---
+
+### `codeflow-mcp`
+
+**CLI surface:**
+
+```bash
+codeflow-mcp tool list
+codeflow-mcp tool invoke <tool-name> --args '{"blueprint": "path.json"}'
+codeflow-mcp server start --port 3100
+```
+
+**MCP server surface:** Connect to any MCP-compatible AI client (Claude Desktop, Cursor, etc.) and call tools directly.
+
+**Isolation test:** Start the MCP server β†’ connect with an MCP client β†’ call `tool list` β†’ assert tools are registered. Call `tool invoke analyze-cycles` with a sample blueprint JSON β†’ assert a cycles result comes back.
+
+**Success signal:** MCP protocol handshake succeeds, tool calls return structured JSON responses.
+
+---
+
+### `codeflow-versioning`
+
+**CLI surface:**
+
+```bash
+codeflow-versioning branch create <blueprint.json> --name "feature-auth"
+codeflow-versioning branch list <blueprint.json>
+codeflow-versioning branch checkout <blueprint.json> --name "feature-auth"
+codeflow-versioning branch diff <blueprint.json> --a main --b feature-auth
+codeflow-versioning branch delete <blueprint.json> --name "feature-auth"
+```
+
+**Isolation test:** Take a sample `blueprint.json` β†’ create 2 branches β†’ list β†’ diff β†’ assert diff shows nodes added in branch B. Delete branch β†’ list β†’ assert it's gone.
+
+**Success signal:** Branch files created at correct paths, diff output shows node-level changes.
+
+---
+
+### `codeflow-prd`
+
+**CLI surface:**
+
+```bash
+codeflow-prd parse ./FEATURES.md
+codeflow-prd build ./FEATURES.md --output blueprint.json
+codeflow-prd reverse ./src --output blueprint.json
+codeflow-prd validate ./blueprint.json
+```
+
+**Isolation test:** Point at `docs/PACKAGE_DECOMPOSITION.md` (this doc) β†’ `parse` β†’ assert it extracts screens, APIs, modules. Point at `src/` of this repo β†’ `reverse` β†’ assert it produces a valid BlueprintGraph JSON with nodes and edges.
+
+**Success signal:** Parsed output has `nodes[]`, `workflows[]`, `edges[]` matching the source content. Reverse mode produces a graph from real code.
+
+---
+
+### `codeflow-analysis`
+
+**CLI surface:**
+
+```bash
+codeflow-analysis cycles ./blueprint.json
+codeflow-analysis smells ./blueprint.json
+codeflow-analysis metrics ./blueprint.json
+codeflow-analysis conflicts ./blueprint.json ./src --threshold 0.7
+codeflow-analysis refactor detect ./blueprint.json ./src
+codeflow-analysis refactor heal ./blueprint.json ./src --auto
+```
+
+**Isolation test:** Use `docs/PACKAGE_DECOMPOSITION.md` (or any sample blueprint) β†’ `cycles` β†’ assert no cycles found on a clean graph. Inject a fake cycle β†’ `cycles` β†’ assert it detects the cycle. Run `smells` β†’ assert god-module/hub-and-spoke detected on a poorly structured graph.
+
+**Success signal:** Each command returns structured JSON with findings. `--json` flag outputs machine-readable results for CI.
+
+---
+
+### `codeflow-execution`
+
+**CLI surface:**
+
+```bash
+codeflow-execution plan ./blueprint.json
+codeflow-execution phases ./blueprint.json
+codeflow-execution run <plan-id> --blueprint ./blueprint.json
+codeflow-execution vcr record ./trace-spans.json --name "login-flow"
+codeflow-execution vcr replay <recording-id>
+codeflow-execution mermaid ./blueprint.json
+codeflow-execution sandbox exec ./blueprint.json --node <node-id> --input '{}'
+```
+
+**Isolation test:** Take a real blueprint β†’ `plan` β†’ assert batches are topologically sorted. `phases` β†’ assert phase order respects dependencies. `mermaid` β†’ assert valid Mermaid syntax output. `vcr record` + `vcr replay` β†’ assert replay matches original execution order.
+
+**Success signal:** Task batches are valid, phases ordered correctly, VCR recording can be replayed, Mermaid is syntactically valid.
+
+---
+
+### `codeflow-agent`
+
+**CLI surface:**
+
+```bash
+# Agent server
+codeflow-agent start --port 3101
+codeflow-agent stop
+codeflow-agent restart
+codeflow-agent sessions list
+codeflow-agent sessions create --model claude-sonnet
+codeflow-agent config list-models
+
+# AI generation (NVIDIA NIM / Llama)
+codeflow-agent generate "build a user authentication module with login and signup" --output blueprint.json
+codeflow-agent status
+
+# Mock/test mode (no API key needed)
+codeflow-agent generate "test prompt" --mock --output blueprint.json
+
+# Per-node code generation + TS validation
+codeflow-agent codegen generate ./blueprint.json --node <node-id> --output ./generated/
+codeflow-agent codegen validate ./generated/auth-module.ts
+
+# Code improvement suggestions
+codeflow-agent codegen suggest ./blueprint.json --node <node-id>
+
+# Agent reasoning (persisted to codeflow-store)
+codeflow-agent sessions reasoning <session-id>   # view reasoning trace
+codeflow-agent sessions replay <session-id>      # replay reasoning + tool calls
+```
+
+**Reasoning persistence:** Agent reasoning (thoughts, tool calls, generated artifacts, session context) is stored in `codeflow-store`. This means reasoning survives restarts and can be checkpointed alongside codeflow execution. `codeflow-versioning` can version reasoning traces β€” you can `git diff` the reasoning from branch A vs branch B. See [Interaction Model: Reasoning β†’ Store β†’ Versioning](#interaction-model-reasoning--store--versioning) below.
+
+**Isolation test:** `start` β†’ wait for daemon β†’ `agent send "hello"` β†’ assert response. `sessions list` β†’ assert at least one session. `stop` β†’ assert daemon is down. With `--mock`, assert deterministic output. `codegen generate` β†’ assert `.ts`/`.tsx` files created. `codegen validate` β†’ assert TypeScript compiler returns zero errors.
+
+**Success signal:** Daemon starts and responds to agent messages. Sessions persist across restarts. Generated code passes `tsc --noEmit`. Reasoning traces are stored and retrievable from `codeflow-store`.
+
+---
+
+### `codeflow-evolution`
+
+**CLI surface:**
+
+```bash
+codeflow-evolution ghost ./blueprint.json
+codeflow-evolution ghost ./blueprint.json --model <model-name>
+codeflow-evolution evolve ./blueprint.json --generations 20 --population 10
+```
+
+**Isolation test:** `ghost` β†’ assert ghost nodes are returned with `suggestedEdges[]`. `evolve` β†’ assert a ranked list of architecture variants is returned after N generations.
+
+**Success signal:** Ghost nodes have `name`, `kind`, `reason`, and `suggestedEdges`. Evolved variants are ranked by fitness score.
+
+---
+
+### `codeflow-canvas`
+
+**Note:** This is primarily a React component package β€” the CLI tests the **non-React logic** only.
+
+**CLI surface (tests the TypeScript modules):**
+
+```bash
+codeflow-canvas render ./blueprint.json --format json
+codeflow-canvas edit ./blueprint.json --node <node-id> --summary "updated summary"
+codeflow-canvas traces overlay ./blueprint.json ./trace-spans.json
+codeflow-canvas heatmap ./blueprint.json ./trace-data.json
+codeflow-canvas layout ./blueprint.json --algorithm dot
+```
+
+**Isolation test:** `render` β†’ assert valid React Flow JSON (nodes + edges). `edit` β†’ modify a node β†’ assert the JSON is updated. `heatmap` β†’ assert each node gets a `color` field. `traces overlay` β†’ assert each span maps to a node with status.
+
+**React component test:** The `.test.tsx` files test the actual React components with `@testing-library/react`. Run `vitest` in the package β€” assert components render, node click opens editor, trace overlay colors nodes.
+
+**Success signal:** TypeScript modules produce correct data structures. React components render without errors. Node editing persists changes.
+
+---
+
+### `codeflow-dtwin`
+
+**CLI surface:**
+
+```bash
+codeflow-dtwin simulate ./blueprint.json ./trace-data.json
+codeflow-dtwin snapshot ./blueprint.json --trace-latest
+codeflow-dtwin active-nodes ./blueprint.json ./trace-data.json
+```
+
+**Isolation test:** `simulate` β†’ assert it returns a simulation with `activeNodes[]`, `path[]`, `duration`. `active-nodes` β†’ assert each node has `isActive`, `lastCallTime`, `callCount`. `snapshot` β†’ assert it returns current graph state with heatmap data.
+
+**Success signal:** Simulation output describes a plausible user flow. Active nodes match trace data. Snapshot is a valid BlueprintGraph with overlay data.
+
+---
+
+## Interaction Model: Reasoning β†’ Store β†’ Versioning
+
+This section answers the question: **does `codeflow-agent` save reasoning on its own, and does it sync with `codeflow-store` or `codeflow-versioning`?**
+
+### How Reasoning Is Stored
+
+`codeflow-agent` does **not** invent its own storage layer. It uses `codeflow-store` as its persistence backend:
+
+```
+codeflow-agent session
+    β”‚
+    β”œβ”€β”€ reasoning trace    β†’  stored in codeflow-store (session-store)
+    β”œβ”€β”€ tool-use history   β†’  stored in codeflow-store (session-store)
+    β”œβ”€β”€ generated artifacts β†’  stored in codeflow-store (run-store / checkpoint-store)
+    └── LLM context window  β†’  stored in codeflow-store (session-store)
+```
+
+Specifically, every `codeflow-agent` session has a corresponding `session` entry in `codeflow-store`. The agent's reasoning (thought process, tool calls, intermediate results) is serialized as structured JSON and stored as part of the session record. This makes reasoning **checkpointable** β€” you can snapshot the entire agent state before a risky operation and restore it if something goes wrong.
+
+### How Versioning Syncs With Reasoning
+
+`codeflow-store` and `codeflow-versioning` are designed to be used together:
+
+```
+codeflow-versioning
+    β”‚
+    β”œβ”€β”€ branch metadata     β†’  stored in codeflow-versioning (branch-store)
+    β”œβ”€β”€ blueprint diffs    β†’  stored in codeflow-versioning
+    └── reasoning traces   β†’  references to codeflow-store session records
+```
+
+When you create a branch in `codeflow-versioning`, the agent's reasoning for that branch is stored as a session in `codeflow-store` with a `branchId` tag. Switching branches (`checkout`) can restore both the blueprint state **and** the agent's reasoning context for that branch β€” so if you check out `feature-auth` branch, the agent resumes with the reasoning it had when working on that branch.
+
+### Sync Flow
+
+```
+1. codeflow-agent does work β†’ reasoning stored in codeflow-store (session)
+2. User creates a branch    β†’ codeflow-versioning snapshots branch
+                            β†’ codeflow-store session tagged with branchId
+3. User switches branches   β†’ codeflow-versioning restores blueprint
+                            β†’ codeflow-agent reasoning context = session from that branch
+4. Checkpoint created       β†’ codeflow-store captures run + reasoning checkpoint
+                            β†’ codeflow-versioning captures branch state
+```
+
+This means **reasoning is versioned by proxy** β€” there's no separate versioning mechanism for reasoning. A branch contains everything (blueprint + agent sessions + checkpoints) through the combined use of `codeflow-versioning` and `codeflow-store`.
+
+### Key Design Decisions
+
+| Question | Answer |
+|----------|--------|
+| Does `codeflow-agent` have its own storage? | **No.** It uses `codeflow-store` as its persistence backend. |
+| Is reasoning versioned? | **By proxy.** `codeflow-store` sessions are tagged with `branchId`. Branch switching restores both blueprint + reasoning context. |
+| Can I replay an agent reasoning trace? | **Yes.** `codeflow-store` sessions are replayable. Use `codeflow-agent sessions replay <session-id>`. |
+| Is reasoning checkpointed? | **Yes.** `codeflow-store` checkpoint captures agent session state alongside execution state. |
+
+---
+
+## Test Fixtures
+
+Each package should ship with a `test-fixtures/` directory containing minimal inputs to run the CLI tests without needing the full monorepo:
+
+```
+<codeflow-package>/
+  test-fixtures/
+    minimal-blueprint.json      # smallest valid BlueprintGraph
+    sample-blueprint.json       # realistic 5-node graph
+    trace-spans.json           # sample trace span data
+    prd-sample.md              # sample PRD for parsing tests
+    repo-sample/               # mini TypeScript repo for reverse mode
+```
+
+This way: `codeflow-analysis cycles ./test-fixtures/sample-blueprint.json` Just Works β€” no setup required.
+
+---
+
+## CI Signal Per Package
+
+Each package's CI should run (in order):
+
+1. `npm run check` β€” TypeScript type check (`tsc --noEmit`)
+2. `npm run test` β€” Unit tests (`vitest run`)
+3. **Isolation CLI test** β€” Run the CLI commands above against `test-fixtures/` and assert expected outputs
+4. `npm run build` β€” TypeScript compile to `dist/`
+
+All four must pass for the package to be considered working.
+
+---
+
+## Post-Decomposition Follow-Up: `openflow-guard` (deferred)
+
+After the backend package extraction is complete (including `codeflow-agent`), add a guard package that enforces commit gates before allowing `git commit` to proceed.
+
+### Purpose
+
+`openflow-guard` is a policy/hook orchestration layer. It does not replace analyzers; it composes existing package capabilities into one pre-commit quality gate.
+
+### Proposed Pre-Commit Gate Order
+
+1. Lint gate (`npm run lint` or package-scoped equivalent)
+2. Test gate (`npm test` or package-scoped equivalent)
+3. Security/diff gate (change-aware checks, security-focused rules, and high-risk findings)
+4. Documentation gate (required doc updates/sync for changed behavior)
+
+Commit is blocked until all gates pass.
+
+### Integration points
+
+- `codeflow-analysis`: cycles/smells/metrics/refactor/conflict and risk-oriented checks
+- `codeflow-versioning` + `codeflow-store`: persist gate reports, failure reasons, and reasoning checkpoints
+- `codeflow-agent`: optional auto-remediation loop that attempts to fix failing gates
+
+### Prompt Packs
+
+Ship prebuilt system prompts for:
+- security review/remediation
+- documentation sync/update
+- optional fix-plan generation for failed gates
+
+### Scope note
+
+This is intentionally deferred until the package backend and OpenCode surfaces are stable, so the guard can reuse package APIs instead of hardcoding monolith paths.

+# AI Coding Risk Playbook
+
+This document turns common "vibe coding" failure modes into explicit CodeFlow guardrails. These are not optional style notes. They are the minimum controls for using AI to write, modify, review, or execute code in this repo.
+
+## What "Vibe Coding" Gets Wrong
+
+The failure mode is not simply "AI wrote bad code." The real problem is unverified momentum:
+
+- code that looks plausible but is not contract-true,
+- tests that look green but prove very little,
+- warnings that get normalized instead of resolved,
+- dependencies and APIs accepted without verification,
+- simulated or heuristic results presented as observed truth,
+- architecture drift introduced by broad, unreviewed generation.
+
+CodeFlow should treat AI as an accelerant, not an authority.
+
+No fake-pass tests, no papering over warnings, and no handwaving about quality. The system should either show evidence or admit the gap.
+
+## Failure Modes And Required Countermeasures
+
+| Risk | What it looks like in practice | Required countermeasure in CodeFlow |
+| --- | --- | --- |
+| Overreliance on model output | The model sounds certain, so developers skip verification | Require schema validation, compile gates, tests, and human review before accepting output |
+| Hallucinated packages or APIs | AI invents a package name, config option, endpoint, or method | Verify existence, ownership, maintenance status, version compatibility, and repo fit before adoption |
+| Passing tests but bad production code | The code passes functional tests but still has code smells, insecure defaults, or weak error handling | Run static analysis, review warnings, inspect contracts and edge cases, and do not equate green tests with release quality |
+| Fake-pass tests | Tests only assert mocks, snapshots, or incidental implementation details | Require behavior assertions, failure-path tests, and boundary-condition coverage |
+| Prompt injection or tool poisoning | Tool descriptions, retrieved docs, or pasted content manipulate the model into unsafe output | Treat retrieved content as untrusted, validate tool metadata, keep least privilege, and keep authorization logic outside the model |
+| Improper output handling | Model output is piped into shell, SQL, file paths, HTML, or tools without validation | Treat model output like user input; validate, sanitize, encode, and constrain before downstream use |
+| Excessive agency | The model can trigger writes, network calls, or execution with too much autonomy | Keep explicit allowlists, minimal privileges, approval gates, and narrow tool scopes |
+| Security regression through convenience | AI introduces insecure defaults, weak validation, or leaky secret handling | Use secure defaults, threat-check sensitive routes, and block raw secret persistence or prompt leakage |
+| Architecture drift | AI duplicates logic, invents new abstractions, or expands file size without need | Search existing patterns first, reuse local abstractions, and reject novelty without justification |
+| Benchmark gaming | The system optimizes for "passes tests" instead of real behavior | Track warnings, failure locality, compile status, contract validation, and runtime evidence alongside tests |
+| Scope explosion | A small task turns into a sweeping refactor | Keep prompts issue-shaped, scope the write set, and prefer incremental verified changes |
+| Unverifiable claims in reviews | A change says "fixed" without evidence | Require command results, file references, and explicit test coverage for behavioral claims |
+
+## Required Workflow For AI-Assisted Changes
+
+### 1. Start from the real contract
+
+Before asking AI to implement anything, provide:
+
+- the target file or boundary,
+- the expected inputs and outputs,
+- existing neighboring patterns,
+- the tests that must pass,
+- the failure mode to avoid.
+
+If the task is vague, the output will usually be vague or wrong.
+
+### 2. Reuse before generation
+
+Ask the model to find the existing pattern first. In this repo, acceptable prompts should resemble:
+
+- "Implement this the same way as the adjacent route."
+- "Extract shared logic instead of duplicating it."
+- "Use the existing schema and store helpers."
+
+Do not ask for a fresh abstraction until you know the repo lacks one.
+
+### 3. Validate in layers
+
+For code written or modified with AI, validate in this order:
+
+1. Schema validity
+2. Compile or typecheck
+3. Unit and integration tests
+4. Static analysis and warnings review
+5. Human review of contracts, security, and duplication
+
+Skipping layers is how plausible garbage ships.
+
+### 4. Treat warnings as work
+
+Warnings are not "good enough for now" unless they are explicitly accepted as a temporary risk with:
+
+- exact warning text,
+- scope,
+- owner,
+- follow-up plan.
+
+If a warning matters enough to mention, it matters enough to track or fix.
+
+### 5. Demand failure evidence, not just success evidence
+
+AI-generated changes should include proof that:
+
+- failure paths were tested,
+- invalid inputs were rejected,
+- edge cases were exercised,
+- downstream consumers handle bad or absent data correctly.
+
+### 6. Keep the model away from unnecessary authority
+
+Do not let AI output:
+
+- choose arbitrary shell commands for production operations,
+- invent filesystem paths outside approved roots,
+- auto-approve risky writes,
+- smuggle secrets into prompts, logs, or exports,
+- decide security policy based on free-form reasoning alone.
+
+## Repo-Specific Rules For CodeFlow
+
+### 7. Graph truthfulness
+
+Never let heuristic, simulated, scaffold, or draft outputs present themselves as observed production truth. Provenance and maturity labels are mandatory.
+
+### 8. Execution truthfulness
+
+Do not mark a node green because code was generated. Mark it green only after observed compile, run, and contract validation evidence.
+
+### 9. Test truthfulness
+
+Every code-bearing function or method should have direct behavioral coverage unless stronger integration coverage makes that redundant. Module and route behavior should have real integration tests. Whole-flow behavior should have scenario coverage.
+
+### 10. Review truthfulness
+
+Do not merge or describe work as complete when any of these remain unverified:
+
+- compile behavior,
+- runtime behavior,
+- warning state,
+- failure-path behavior,
+- dependency validity,
+- security boundaries,
+- drift against local patterns.
+

+# CodeFlow Execution And Validation Contract
+
+This document defines the required production target for how CodeFlow should execute nodes, validate outcomes, and surface failures. It is intentionally stricter than the current implementation. Until the product reaches this bar, UI and API copy must not imply that the full contract already exists.
+
+## Why This Exists
+
+CodeFlow should not behave like a vague code generator. It should behave like a graph-aware execution and verification system where:
+
+- each runnable leaf node can be executed independently,
+- composite nodes reflect the truth of their children,
+- whole-program runs show which exact path passed or failed,
+- return values and side effects are validated before they unlock downstream nodes,
+- a user can drill from a failed module into the exact failing function or method.
+
+## Required Runtime Model
+
+### 1. Execution levels
+
+CodeFlow should distinguish three levels of execution:
+
+- Leaf execution: a directly runnable function, API handler, class method, or UI interaction harness.
+- Composite execution: a module, service, or screen made up of multiple child execution units.
+- Graph execution: an end-to-end run across multiple nodes and edges in dependency order.
+
+Every code-bearing node must be mapped to one of these:
+
+- `directly-runnable`
+- `runnable-through-child-nodes`
+- `not-runnable-yet`
+
+If a node is not runnable yet, the reason must be explicit in the UI and persisted execution record.
+
+### 2. Pass and fail semantics
+
+A node run is a real pass only if all of the following succeed:
+
+1. The artifact compiles or typechecks at the required boundary.
+2. The runtime harness executes without an unhandled failure.
+3. Input contracts are validated before invocation.
+4. Output contracts are validated after invocation.
+5. Required side effects are observed or asserted.
+6. Any value passed to a downstream edge is validated before consumption.
+
+If any of those fail, the node is red, not green.
+
+### 3. Status meanings
+
+These meanings should be enforced consistently across the graph, inspector, logs, and persisted run records:
+
+- Green: observed pass from real execution and validation.
+- Red: observed failure from real execution or validation.
+- Yellow: warning, flaky, partial, or degraded outcome that did not meet the clean pass bar.
+- Gray: not run.
+- Blue or striped badge: simulated, heuristic, or preview evidence that is not a real pass.
+
+Green must never mean "the model thinks this should work."
+
+## Whole-Graph Run Behavior
+
+### 4. Graph execution flow
+
+When a user clicks run for the whole program, CodeFlow should:
+
+1. Build an execution plan from the graph.
+2. Execute runnable leaf nodes in dependency order.
+3. Emit a per-step execution event for each node and edge.
+4. Validate returned values before releasing downstream nodes.
+5. Mark downstream nodes as blocked if an upstream node fails or returns invalid output.
+6. Persist exact evidence for each step.
+
+### 5. Execution evidence
+
+Each execution step should persist a structured record with at least:
+
+- `runId`
+- `nodeId`
+- `parentNodeId` when applicable
+- `methodName` or `entrypointName` when applicable
+- `input`
+- `outputSummary`
+- `validationStatus`
+- `stderr`
+- `stdout`
+- `startedAt`
+- `finishedAt`
+- `durationMs`
+- `downstreamEdgeIds`
+- `blockedByNodeId` when blocked
+
+### 6. Edge handoff validation
+
+Edges are not just lines on a diagram. They are contracts.
+
+Before a value is passed from node A to node B, CodeFlow should validate:
+
+- the producing node actually emitted a value,
+- the value matches the declared output contract of node A,
+- the value matches the declared input contract of node B,
+- any required transformation step is explicit and testable.
+
+If the handoff fails validation, the failure belongs to the edge handoff and the downstream node must not be marked green.
+
+## Composite Nodes And Drill-Down
+
+### 7. Module and class truthfulness
+
+Composite nodes must derive their state from children:
+
+- A module is green only when all required child executions are green.
+- A module is red if any required child execution fails.
+- A module is yellow if children are mixed, partial, skipped, or degraded.
+
+The same rule applies to class nodes with multiple methods.
+
+### 8. Drill-down behavior
+
+Double-clicking a failed module or class should open the exact failing child execution, including:
+
+- method or function name,
+- failing assertion,
+- input payload,
+- returned value or thrown error,
+- stack trace or stderr,
+- test case or scenario name,
+- upstream dependency context.
+
+If the graph has only coarse nodes today, the runtime must still materialize child execution records instead of collapsing everything into one module-level pass or fail.
+
+## Test Contract
+
+### 9. Minimum required test layers
+
+For production-grade execution visibility, CodeFlow should require:
+
+- Function or method tests for leaf logic.
+- Route or service integration tests for module boundaries.
+- Scenario or end-to-end tests for critical graph workflows.
+
+### 10. No fake-pass coverage
+
+The following do not count as enough evidence:
+
+- a test that only checks whether a mock was called,
+- a test that snapshots output without validating behavior,
+- a graph run that only checks exit code,
+- a module marked green because one child passed while others were skipped,
+- simulated traces shown as if they were observed execution.
+
+### 11. Recommended test strategy
+
+For each code-bearing node, prefer:
+
+- one happy-path test,
+- one failure-path test,
+- one edge-case test,
+- one contract-shape test when inputs or outputs are structured,
+- one integration test where the node hands real data to its most important downstream dependency.
+
+For bugs, prefer fail-to-pass first, then keep pass-to-pass coverage green.
+
+## Implementation Guidance For CodeFlow
+
+### 12. Interpreter or compiler expectations
+
+CodeFlow does not need a custom language interpreter. The practical model is:
+
+- compile TypeScript or TSX artifacts in an isolated workspace,
+- run per-node harnesses for functions, APIs, class methods, and UI interactions,
+- capture structured outputs and validation results,
+- project those results back onto graph nodes and edges.
+
+For composite nodes, the system should execute the underlying callable children rather than pretending the module itself is a callable unit.
+
+### 13. Reuse and leverage existing tools
+
+Do not reinvent core infrastructure when proven tools already solve the problem:
+
+- Use TypeScript compilation for compile gates.
+- Use Zod or equivalent schema validation for input and output contracts.
+- Use Vitest or Jest for unit and integration tests.
+- Use Playwright for browser or workflow verification.
+- Use structured execution events rather than ad hoc console parsing.
+
+### 14. Release bar for this feature area
+
+This runtime model should not be called production-ready until:
+
+- leaf-node execution is real for supported node kinds,
+- composite-node drill-down exists,
+- edge handoff validation exists,
+- graph colors map to observed evidence,
+- fake-pass states are eliminated,
+- tests cover the execution pipeline itself.

+## Security Validation Flow
+
+### Phase 1: Input Validation (Zod Schema)
+
+1. **Parse and validate request body/query** using Zod schemas
+2. **Check path is non-empty** - reject EMPTY_PATH
+3. **Check path is relative** - reject ABSOLUTE_PATH
+4. **Check content size** (POST only) - reject PAYLOAD_TOO_LARGE (>10MB)
+
+### Phase 2: Path Security Validation

+
+## Implementation Notes
+
+### Path Normalization Strategy
+
+Always use **defense in depth** with multiple normalization passes:
+
+```typescript
+function normalizeAndSecurePath(inputPath: string): string {
+  // First: standard normalization
+  let normalized = path.normalize(inputPath);
+
+  // Second: POSIX style for consistency
+  normalized = path.posix.normalize(normalized.replace(/\\/g, "/"));
+
+  // Third: remove any leading/trailing whitespace
+  normalized = normalized.trim();
+
+  // Fourth: remove leading slashes (prevent absolute)
+  normalized = normalized.replace(/^\/+/, "");
+
+  return normalized;
+}
+```
+
+### Error Handling Principles
+
+1. **Never expose internal paths** - Log absolute paths to server logs only, never to client
+2. **Never expose stack traces** - Generic internal error messages in production
+3. **Consistent error format** - Always use the Zod error schema structure
+4. **Appropriate HTTP status codes** - Map error codes to semantic HTTP status
+
+### Security Best Practices
+
+1. **Canonicalize before validation** - Always normalize path before checking extensions
+2. **Whitelist, not blacklist** - Only allow known-safe extensions
+3. **Double-check resolved paths** - Verify final resolved path is still under root
+4. **Use file descriptor operations** - Avoid TOCTOU race conditions where possible
+5. **Rate limiting** - Consider adding rate limits per IP for write operations
+
+---
+
+## Testing Strategy
+
+### Security Test Cases
+
+```typescript
+// Path traversal attempts
+["../etc/passwd", "../../.env", "foo/../../../secret", ".\\..\\windows\\system.ini"]
+
+// Null byte injection
+["file.txt\x00.js", "normal.txt\x00"]
+
+// Absolute path attempts
+["/etc/passwd", "C:/Windows/system.ini", "/var/www/html", "\\server\share"]
+
+// Forbidden characters
+["file<>.txt", "file|?.txt", "file:*.txt"]
+
+// Extension bypasses
+["file.js.exe", "file.txt.pdf", ".htaccess", "../config.xml"]
+```
+
+### Edge Cases
+
+- Empty path ("")
+- Current directory reference ("./file.txt")
+- Multiple slashes ("///etc/passwd")
+- Unicode paths ("Ρ„Π°ΠΉΠ».txt")
+- Very long paths (>1024 chars)
+- Special files (pipes, sockets, device files)
+- Symlink traversal (if symlinks exist in repo)

+# codeflow-mcp Package Decomposition Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Extract `src/lib/blueprint/mcp.ts`, its test, and the two MCP API routes into a standalone npm package `@abhinav2203/codeflow-mcp` that works in isolation β€” no monorepo, no Next.js app required.
+
+**Architecture:** The package exposes an MCP client library (`listMcpTools`, `invokeMcpTool`) and an MCP server that wraps CodeFlow blueprint operations. API routes in the Next.js app are replaced with thin re-exports from the package. During development, packages use `workspace:*` ranges; once published to npm, these resolve to published semver.
+
+**Tech Stack:** TypeScript, Node.js, `zod`, `vitest`, MCP JSON-RPC protocol

+    "@abhinav2203/codeflow-core": "workspace:*",
+    "zod": "^3.0.0"
+  },
+  "devDependencies": {
+    "typescript": "^5.0.0",
+    "vitest": "^1.0.0"
+  }
+}
+```
+
+- [ ] **Step 0.3: Create `packages/codeflow-mcp/tsconfig.json`**
+
+```json
+{
+  "extends": '../../../tsconfig.json",
+  "compilerOptions": {
+    "outDir": "./dist",
+    "rootDir": "./src"
+  },
+  "include": ["src"]
+}
+```
+
+- [ ] **Step 0.4: Create `packages/codeflow-mcp/vitest.config.ts`**
+
+```typescript
+import { defineConfig } from "vitest/config";
+
+export default defineConfig({
+  test: {
+    environment: "node",
+    include: ["src/**/*.test.ts"]
+  }
+});
+```
+
+- [ ] **Step 0.5: Create `scripts/wrap-cli.mjs`** (wraps the TS compile step for the CLI bin β€” the bin entry must be a .js file)
+
+```javascript
+import { writeFileSync } from "fs";
+import { fileURLToPath } from "url";
+import { dirname, join } from "path";
+
+const __dirname = dirname(fileURLToPath(import.meta.url));
+const srcDir = join(__dirname, "../dist");
+const distBin = join(srcDir, "bin");
+
+// The CLI is a thin wrapper that loads the compiled module
+writeFileSync(join(distBin, "cli.js"), `#!/usr/bin/env node
+import { main } from "../invoke/index.js";
+main();
+`);
+```
+
+- [ ] **Step 0.6: Run `npm install` in the package**
+
+Run: `cd packages/codeflow-mcp && npm install`
+Expected: Dependencies resolved without errors
+
+---
+
+## Step 1 β€” Move core `mcp.ts` logic
+
+- [ ] **Step 1.1: Create `packages/codeflow-mcp/src/index.ts`** β€” copy `src/lib/blueprint/mcp.ts` content, but:
+  - Remove `@/lib/blueprint/schema` import β€” import `McpTool`, `McpToolResult` types from `@abhinav2203/codeflow-core`
+  - Keep all functions: `sendJsonRpc`, `listMcpTools`, `invokeMcpTool`, `extractTextFromMcpResult`
+
+- [ ] **Step 1.2: Run check**
+
+Run: `cd packages/codeflow-mcp && npm run check`
+Expected: No TypeScript errors (types resolve via workspace `codeflow-core`)
+
+- [ ] **Step 1.3: Run tests**
+
+Run: `cd packages/codeflow-mcp && npm run test`
+Expected: All tests pass
+
+- [ ] **Step 1.4: Commit**
+
+```bash
+cd packages/codeflow-mcp
+git add src/index.ts package.json tsconfig.json vitest.config.ts scripts/
+git commit -m "feat(mcp): move core MCP client library to package"
+```
+
+---
+
+## Step 2 β€” Move API routes as package exports
+
+- [ ] **Step 2.1: Create `packages/codeflow-mcp/src/invoke.ts`** β€” copy `src/app/api/mcp/invoke/route.ts`
+  - Change import `from "@/lib/blueprint/mcp"` β†’ `from "@abhinav2203/codeflow-mcp"`
+  - Change import `from "next/server"` β†’ `from "next"; import type { NextResponse } from "next"`
+  - Keep all SSRF validation, header filtering, error handling
+
+- [ ] **Step 2.2: Create `packages/codeflow-mcp/src/invoke.test.ts`** β€” copy `src/app/api/mcp/invoke/route.test.ts`
+  - Change import `from "@/app/api/mcp/invoke/route"` β†’ `from "./invoke"`
+
+- [ ] **Step 2.3: Create `packages/codeflow-mcp/src/tools.ts`** β€” copy `src/app/api/mcp/tools/route.ts`
+  - Change import `from "@/lib/blueprint/mcp"` β†’ `from "@abhinav2203/codeflow-mcp"`
+  - Change import `from "next/server"` β†’ `from "next"; import type { NextResponse } from "next"`
+
+- [ ] **Step 2.4: Create `packages/codeflow-mcp/src/tools.test.ts`** β€” copy `src/app/api/mcp/tools/route.test.ts`
+  - Change import `from "@/app/api/mcp/tools/route"` β†’ `from "./tools"`
+
+- [ ] **Step 2.5: Create `packages/codeflow-mcp/src/index.test.ts`** β€” copy `src/lib/blueprint/mcp.test.ts`
+  - Change import `from "@/lib/blueprint/mcp"` β†’ `from "./index"`
+  - Change import `from "@/lib/blueprint/schema"` β†’ `from "@abhinav2203/codeflow-core"`
+
+- [ ] **Step 2.6: Run check and tests**
+
+Run: `cd packages/codeflow-mcp && npm run check && npm run test`
+Expected: Both pass
+
+- [ ] **Step 2.7: Commit**
+
+```bash
+cd packages/codeflow-mcp
+git add src/invoke.ts src/invoke.test.ts src/tools.ts src/tools.test.ts src/index.test.ts
+git commit -m "feat(mcp): move API routes as package sub-exports"
+```
+
+---
+
+## Step 3 β€” Wire Next.js app to import from package
+
+- [ ] **Step 3.1: Replace `src/app/api/mcp/invoke/route.ts`** with:
+
+```typescript
+// Re-export from package β€” implementation lives in the package now
+export { POST as invokeRoute } from "@abhinav2203/codeflow-mcp/invoke";
+```
+
+- [ ] **Step 3.2: Replace `src/app/api/mcp/tools/route.ts`** with:
+
+```typescript
+export { POST as toolsRoute } from "@abhinav2203/codeflow-mcp/tools";
+```
+
+- [ ] **Step 3.3: Update test files** β€” update the test imports in both route.test.ts files so they still work with the Next.js app.
+
+For `src/app/api/mcp/invoke/route.test.ts`, the test imports `POST` from the route. Since we've replaced the route with a re-export, we need to make sure the route still exports `POST`:
+
+```typescript
+// In src/app/api/mcp/invoke/route.ts β€” replace with:
+import { POST } from "@abhinav2203/codeflow-mcp/invoke";
+export { POST };
+```
+
+```typescript
+// In src/app/api/mcp/tools/route.ts β€” replace with:
+import { POST } from "@abhinav2203/codeflow-mcp/tools";
+export { POST };
+```
+
+- [ ] **Step 3.4: Run full app type check**
+
+Run: `cd /Users/abhinavnehra/git/CodeFlow && npm run check`
+Expected: No TypeScript errors
+
+- [ ] **Step 3.5: Commit**
+
+```bash
+cd /Users/abhinavnehra/git/CodeFlow
+git add src/app/api/mcp/invoke/route.ts src/app/api/mcp/tools/route.ts
+git commit -m "feat(mcp): wire API routes to import from @abhinav2203/codeflow-mcp"
+```
+
+---
+
+## Step 4 β€” Add CLI bin and test-fixtures for isolation testing
+
+- [ ] **Step 4.1: Create `packages/codeflow-mcp/src/bin/cli.ts`**
+
+```typescript
+#!/usr/bin/env node
+import { listMcpTools, invokeMcpTool } from "../index.js";
+
+const [cmd, ...args] = process.argv.slice(2);
+
+if (cmd === "tool" && args[0] === "list") {
+  const serverUrl = args[1] ?? "http://localhost:3001/mcp";
+  const tools = await listMcpTools(serverUrl);
+  console.json({ tools });
+} else if (cmd === "tool" && args[0] === "invoke") {
+  const toolName = args[1];
+  const serverUrl = args[2] ?? "http://localhost:3001/mcp";
+  const rawArgs = args[3] ?? "{}";
+  const result = await invokeMcpTool(serverUrl, toolName, JSON.parse(rawArgs));
+  console.json({ result });
+} else {
+  console.log("Usage: codeflow-mcp tool list <serverUrl>\n       codeflow-mcp tool invoke <name> <serverUrl> <args-json>");
+}
+```
+
+- [ ] **Step 4.2: Create `test-fixtures/minimal-blueprint.json`**
+
+A minimal BlueprintGraph JSON for CLI testing.
+
+- [ ] **Step 4.3: Run isolation test**
+
+Run: `cd packages/codeflow-mcp && npm run build && node dist/bin/cli.js tool list http://localhost:9999/mcp`
+Expected: Returns 400 with connection error (server not running β€” this proves the CLI runs and makes the HTTP call)
+
+- [ ] **Step 4.4: Commit**
+
+```bash
+cd packages/codeflow-mcp
+git add src/bin/cli.ts test-fixtures/
+git commit -m "feat(mcp): add CLI bin for isolation testing"
+```
+
+---
+
+## Step 5 β€” Final verification
+
+- [ ] **Step 5.1: Run all package checks**
+
+Run: `cd packages/codeflow-mcp && npm run check && npm run test && npm run build`
+Expected: `tsc --noEmit` passes, `vitest run` passes, build produces `dist/` with all entry points
+
+- [ ] **Step 5.2: Verify app still works**
+
+Run: `cd /Users/abhinavnehra/git/CodeFlow && npm run check`
+Expected: App type-checks with the rewired routes
+

+# codeflow-versioning 0.1.0 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Extract blueprint branching and diff into a standalone npm package `@abhinav2203/codeflow-versioning` that works in isolation β€” no Next.js app required.
+
+**Architecture:** The package exposes two sub-modules: `./branch` (create/snapshot/diff) and `./store` (persistence to filesystem). API routes in the Next.js app are replaced with thin re-exports from the package. The MCP server gains branch tools via the package.
+
+**Tech Stack:** TypeScript, Node.js, `zod`, `vitest`, `uuid`, `@abhinav2203/codeflow-core`

+Shared utilities (import from `@abhinav2203/codeflow-core`, do not copy):
+- `src/lib/blueprint/store-paths.ts` β†’ `branchDirForProject`, `branchPath` (already moved to `codeflow-store/src/shared/`)
+- `src/lib/blueprint/schema.ts` β†’ `GraphBranch`, `BranchDiff`, `NodeDiff`, `EdgeDiff`, all related schemas
+
+---
+
+## Step 0 β€” Scaffold Package Skeleton
+
+- [ ] **Step 0.1: Create directory structure**
+
+```bash
+mkdir -p packages/codeflow-versioning/src/{bin,invoke}
+mkdir -p packages/codeflow-versioning/test-fixtures
+```
+
+- [ ] **Step 0.2: Create `packages/codeflow-versioning/package.json`**
+
+```json
+{
+  "name": "@abhinav2203/codeflow-versioning",
+  "version": "0.1.0",
+  "private": true,
+  "type": "module",

+    "build": "tsc --outDir dist --declaration --declarationMap",
+    "clean": "rm -rf dist"
+  },
+  "dependencies": {
+    "@abhinav2203/codeflow-core": "workspace:*",
+    "@abhinav2203/codeflow-store": "workspace:*",
+    "uuid": "^11.0.0",
+    "zod": "^3.0.0"
+  },
+  "devDependencies": {
+    "@types/node": "^22.0.0",
+    "@types/uuid": "^10.0.0",
+    "typescript": "^5.7.0",
+    "vitest": "^3.0.0"
+  }
+}
+```
+
+- [ ] **Step 0.3: Create `packages/codeflow-versioning/tsconfig.json`**
+
+```json
+{
+  "extends": "../../../tsconfig.json",
+  "compilerOptions": {
+    "outDir": "./dist",
+    "rootDir": "./src"
+  },
+  "include": ["src"]
+}
+```
+
+- [ ] **Step 0.4: Create `packages/codeflow-versioning/vitest.config.ts`**
+
+```typescript
+import { defineConfig } from "vitest/config";
+
+export default defineConfig({
+  test: {
+    environment: "node",
+    include: ["src/**/*.test.ts"]
+  }
+});
+```
+
+- [ ] **Step 0.5: Run `npm install` in the package**
+
+Run: `cd packages/codeflow-versioning && npm install`
+Expected: Dependencies resolved without errors
+
+- [ ] **Step 0.6: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add package.json tsconfig.json vitest.config.ts
+git commit -m "feat(versioning): scaffold package skeleton v0.1.0"
+```
+
+---
+
+## Step 1 β€” Move `branches.ts` β†’ `./branch`
+
+- [ ] **Step 1.1: Create `packages/codeflow-versioning/src/branch/index.ts`**
+
+Copy `src/lib/blueprint/branches.ts` content, with these changes:
+- Remove `import type { ... } from "@/lib/blueprint/schema"` β†’ import from `@abhinav2203/codeflow-core/schema`
+- Remove `import { blueprintGraphSchema } from "@/lib/blueprint/schema"` β†’ same
+- Remove `import crypto from "node:crypto"` β†’ use `uuid` package instead (`import { v4 as uuidv4 } from "uuid"`)
+- `createBranchId` function: replace `crypto.randomUUID()` with `uuidv4()`
+- Export both `createBranch` and `diffBranches`
+- Export `createBranchId` for internal use
+
+Key functions to export:
+```typescript
+export const createBranchId = (): string => uuidv4();
+export const createBranch = ({ graph, name, description?, parentBranchId? }: { ... }): GraphBranch
+export const diffBranches = (base: BlueprintGraph, compare: BlueprintGraph, baseId?, compareId?): BranchDiff
+```
+
+- [ ] **Step 1.2: Run check**
+
+Run: `cd packages/codeflow-versioning && npm run check`
+Expected: No TypeScript errors
+
+- [ ] **Step 1.3: Run tests**
+
+Run: `cd packages/codeflow-versioning && npm run test`
+Expected: All tests pass
+
+- [ ] **Step 1.4: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add src/branch/index.ts
+git commit -m "feat(versioning): move createBranch and diffBranches to branch module"
+```
+
+---
+
+## Step 2 β€” Move `branch-store.ts` β†’ `./store`
+
+- [ ] **Step 2.1: Create `packages/codeflow-versioning/src/store/index.ts`**
+
+Copy `src/lib/blueprint/branch-store.ts` content, with these changes:
+- Remove `import type { GraphBranch } from "@/lib/blueprint/schema"` β†’ import from `@abhinav2203/codeflow-core/schema`
+- Remove `import { branchDirForProject, branchPath } from "@/lib/blueprint/store-paths"` β†’ import from `@abhinav2203/codeflow-store/shared`
+- Re-export `saveBranch`, `loadBranch`, `loadBranches`, `deleteBranch`
+
+Key functions to export:
+```typescript
+export const saveBranch = async (branch: GraphBranch): Promise<void>
+export const loadBranch = async (projectName: string, branchId: string): Promise<GraphBranch | null>
+export const loadBranches = async (projectName: string): Promise<GraphBranch[]>
+export const deleteBranch = async (projectName: string, branchId: string): Promise<void>
+```
+
+> **Note:** `branchDirForProject` and `branchPath` already exist in `codeflow-store/src/shared/utils.ts`. The package reuses them by importing from `@abhinav2203/codeflow-store` β€” no duplication needed.
+
+- [ ] **Step 2.2: Run check and tests**
+
+Run: `cd packages/codeflow-versioning && npm run check`
+Expected: No TypeScript errors
+
+- [ ] **Step 2.3: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add src/store/index.ts
+git commit -m "feat(versioning): move branch store persistence to store module"
+```
+
+---
+
+## Step 3 β€” Move API routes β†’ `./invoke`
+
+- [ ] **Step 3.1: Create `packages/codeflow-versioning/src/invoke.ts`**
+
+Consolidate all three route files into a single invoke module. This replaces the Next.js route handlers with plain async functions callable without Next.js.
+
+```typescript
+// GET /branches?projectName=xxx
+export const listBranches = async (projectName: string): Promise<GraphBranch[]>
+
+// POST /branches
+export const createBranch = async (payload: {
+  graph: BlueprintGraph
+  name: string
+  description?: string
+  parentBranchId?: string
+}): Promise<GraphBranch>
+
+// GET /branches/:id?projectName=xxx
+export const getBranch = async (
+  projectName: string,
+  branchId: string
+): Promise<GraphBranch | null>
+
+// DELETE /branches/:id?projectName=xxx
+export const removeBranch = async (projectName: string, branchId: string): Promise<void>
+```
+
+For `createBranch`:
+- Accept the same Zod schema as `src/app/api/branches/route.ts`
+- Call `createBranch` from `./branch/index.js`
+- Call `saveBranch` from `./store/index.js`
+- Return the created `GraphBranch`
+
+For `listBranches`:
+- Accept `projectName: string`
+- Call `loadBranches` from `./store/index.js`
+- Return `GraphBranch[]`
+
+For `getBranch`:
+- Accept `projectName` and `branchId` (validate with same regex as original route)
+- Call `loadBranch` from `./store/index.js`
+- Return `null` if not found
+
+For `removeBranch`:
+- Accept `projectName` and `branchId` (validate with same regex)
+- Call `deleteBranch` from `./store/index.js`
+
+- [ ] **Step 3.2: Create `packages/codeflow-versioning/src/diff.ts`**
+
+```typescript
+export const computeDiff = async (payload: {
+  baseGraph: BlueprintGraph
+  compareGraph: BlueprintGraph
+  baseId?: string
+  compareId?: string
+}): Promise<BranchDiff>
+```
+
+- Call `diffBranches` from `./branch/index.js`
+- Return the `BranchDiff` result
+
+- [ ] **Step 3.3: Run check**
+
+Run: `cd packages/codeflow-versioning && npm run check`
+Expected: No TypeScript errors
+
+- [ ] **Step 3.4: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add src/invoke.ts src/diff.ts
+git commit -m "feat(versioning): move API routes to invoke module"
+```
+
+---
+
+## Step 4 β€” Wire Next.js app to import from package
+
+- [ ] **Step 4.1: Replace `src/app/api/branches/route.ts`** with:
+
+```typescript
+import { createBranch, listBranches } from "@abhinav2203/codeflow-versioning/branch";
+import { saveBranch, loadBranches } from "@abhinav2203/codeflow-versioning/store";
+
+export async function GET(request: Request) {
+  const { searchParams } = new URL(request.url);
+  const projectName = searchParams.get("projectName");
+  if (!projectName) {
+    return NextResponse.json({ error: "projectName required" }, { status: 400 });
+  }
+  const branches = await listBranches(projectName);
+  return NextResponse.json({ branches });
+}
+
+export async function POST(request: Request) {
+  try {
+    const { graph, name, description, parentBranchId } = await request.json();
+    const branch = await createBranch({ graph, name, description, parentBranchId });
+    await saveBranch(branch);
+    return NextResponse.json({ branch });
+  } catch (error) {
+    return NextResponse.json(
+      { error: error instanceof Error ? error.message : "Failed to create branch." },
+      { status: 400 }
+    );
+  }
+}
+```
+
+- [ ] **Step 4.2: Replace `src/app/api/branches/[id]/route.ts`** with:
+
+```typescript
+import { getBranch, removeBranch } from "@abhinav2203/codeflow-versioning/branch";
+import { loadBranch, deleteBranch } from "@abhinav2203/codeflow-versioning/store";
+
+// GET /branches/:id
+export async function GET(...) { ... }
+
+// DELETE /branches/:id
+export async function DELETE(...) { ... }
+```
+
+- [ ] **Step 4.3: Replace `src/app/api/branches/diff/route.ts`** with:
+
+```typescript
+import { computeDiff } from "@abhinav2203/codeflow-versioning/diff";
+
+export async function POST(request: Request) {
+  try {
+    const diff = await computeDiff(await request.json());
+    return NextResponse.json({ diff });
+  } catch (error) {
+    return NextResponse.json(
+      { error: error instanceof Error ? error.message : "Failed to compute diff." },
+      { status: 400 }
+    );
+  }
+}
+```
+
+- [ ] **Step 4.4: Run full app type check**
+
+Run: `cd /Users/abhinavnehra/git/CodeFlow && npm run check`
+Expected: No TypeScript errors
+
+- [ ] **Step 4.5: Commit**
+
+```bash
+cd /Users/abhinavnehra/git/CodeFlow
+git add src/app/api/branches/route.ts src/app/api/branches/\[id\]/route.ts src/app/api/branches/diff/route.ts
+git commit -m "feat(versioning): wire branches API routes to @abhinav2203/codeflow-versioning"
+```
+
+---
+
+## Step 5 β€” Add MCP tools
+
+- [ ] **Step 5.1: Create `packages/codeflow-versioning/src/tools.ts`**
+
+Register these tools in the MCP registry:
+
+```typescript
+// tool: versioning_branch_list
+// args: { projectName: string }
+// returns: { branches: GraphBranch[] }
+
+// tool: versioning_branch_create
+// args: { projectName: string, graph: BlueprintGraph, name: string, description?: string, parentBranchId?: string }
+// returns: { branch: GraphBranch }
+
+// tool: versioning_branch_get
+// args: { projectName: string, branchId: string }
+// returns: { branch: GraphBranch } | { error: string }
+
+// tool: versioning_branch_delete
+// args: { projectName: string, branchId: string }
+// returns: { deleted: true }
+
+// tool: versioning_diff
+// args: { baseGraph: BlueprintGraph, compareGraph: BlueprintGraph, baseId?: string, compareId?: string }
+// returns: { diff: BranchDiff }
+```
+
+- [ ] **Step 5.2: Register tools in `codeflow-mcp`**
+
+In `packages/codeflow-mcp/src/tools.ts`, add:
+
+```typescript
+import { versioningTools } from "@abhinav2203/codeflow-versioning/tools";
+
+// Merge into existing tools registry
+export const allTools = [...baseTools, ...versioningTools];
+```
+
+- [ ] **Step 5.3: Run check and tests**

+# codeflow-versioning 0.2.0 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use `superpowers:subagent-driven-development` (recommended) or `superpowers:executing-plans` to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Extract blueprint branching and diff into a standalone npm package `@abhinav2203/codeflow-versioning` that works in isolation β€” no Next.js app required β€” with deep CodeRAG integration for reasoning-enriched branch diffs and natural-language branch queries.
+
+**Architecture:** The package exposes four sub-modules: `./branch` (create/snapshot/diff), `./store` (persistence), `./reasoning` (checkpoint snapshots), and `./coderag` (semantic branch search + diff explanation). The MCP server gains branch + CodeRAG tools via the package.
+
+**Tech Stack:** TypeScript, Node.js, `zod`, `vitest`, `uuid`, `@abhinav2203/codeflow-core`, `@abhinav2203/codeflow-store`, `@abhinav2203/coderag`

+## Step 0 β€” Scaffold Package Skeleton
+
+- [ ] **Step 0.1: Create directory structure**
+
+```bash
+mkdir -p packages/codeflow-versioning/src/coderag
+mkdir -p packages/codeflow-versioning/test-fixtures
+```
+
+- [ ] **Step 0.2: Create `packages/codeflow-versioning/package.json`**
+
+```json

+    "typescript": "^5.7.0",
+    "vitest": "^3.0.0"
+  }
+}
+```
+
+- [ ] **Step 0.3: Create `packages/codeflow-versioning/tsconfig.json`**
+
+```json
+{
+  "extends": "../../../tsconfig.json",
+  "compilerOptions": {
+    "outDir": "./dist",
+    "rootDir": "./src"
+  },
+  "include": ["src"]
+}
+```
+
+- [ ] **Step 0.4: Create `packages/codeflow-versioning/vitest.config.ts`**
+
+```typescript
+import { defineConfig } from "vitest/config";
+
+export default defineConfig({
+  test: {
+    environment: "node",
+    include: ["src/**/*.test.ts"]
+  }
+});
+```
+
+- [ ] **Step 0.5: Run `npm install` in the package**
+
+Run: `cd packages/codeflow-versioning && npm install`
+Expected: Dependencies resolved without errors
+
+- [ ] **Step 0.6: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add package.json tsconfig.json vitest.config.ts
+git commit -m "feat(versioning): scaffold package skeleton v0.2.0"
+```
+
+---
+
+## Step 1 β€” Move `branches.ts` β†’ `./branch`
+
+- [ ] **Step 1.1: Create `packages/codeflow-versioning/src/branch.ts`**
+
+Copy `src/lib/blueprint/branches.ts` content, with these changes:
+- Remove `import type { ... } from "@/lib/blueprint/schema"` β†’ import from `@abhinav2203/codeflow-core/schema`
+- Remove `import { blueprintGraphSchema } from "@/lib/blueprint/schema"` β†’ same
+- Remove `import crypto from "node:crypto"` β†’ use `uuid` package instead (`import { v4 as uuidv4 } from "uuid"`)
+- `createBranchId` function: replace `crypto.randomUUID()` with `uuidv4()`
+- Export both `createBranch` and `diffBranches`
+- Export `createBranchId` for internal use
+
+Key functions to export:
+```typescript
+export const createBranchId = (): string => uuidv4();
+export const createBranch = ({ graph, name, description?, parentBranchId? }: { ... }): GraphBranch
+export const diffBranches = (base: BlueprintGraph, compare: BlueprintGraph, baseId?, compareId?): BranchDiff
+```
+
+- [ ] **Step 1.2: Run check**
+
+Run: `cd packages/codeflow-versioning && npm run check`
+Expected: No TypeScript errors
+
+- [ ] **Step 1.3: Run tests**
+
+Run: `cd packages/codeflow-versioning && npm run test`
+Expected: All tests pass
+
+- [ ] **Step 1.4: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add src/branch.ts
+git commit -m "feat(versioning): move createBranch and diffBranches to branch module"
+```
+
+---
+
+## Step 2 β€” Move `branch-store.ts` β†’ `./store`
+
+- [ ] **Step 2.1: Create `packages/codeflow-versioning/src/store.ts`**
+
+Re-export from `@abhinav2203/codeflow-store/branch` β€” no copy needed, just re-export for package API surface:
+
+```typescript
+export { saveBranch, loadBranch, loadBranches, deleteBranch } from "@abhinav2203/codeflow-store/branch";
+```
+
+> **Note:** `branchDirForProject` and `branchPath` already exist in `codeflow-store/src/shared/utils.ts`. The package reuses them by importing from `@abhinav2203/codeflow-store` β€” no duplication needed.
+
+- [ ] **Step 2.2: Run check and tests**
+
+Run: `cd packages/codeflow-versioning && npm run check`
+Expected: No TypeScript errors
+
+- [ ] **Step 2.3: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add src/store.ts
+git commit -m "feat(versioning): re-export branch store from codeflow-store"
+```
+
+---
+
+## Step 3 β€” Reasoning Integration (NEW)
+
+This is the key v0.2.0 addition. When creating a branch, optionally snapshot reasoning checkpoints so the branch retains the full decision-making context.
+
+- [ ] **Step 3.1: Create `packages/codeflow-versioning/src/reasoning/index.ts`**
+
+```typescript
+import type { ReasoningCheckpoint } from "@abhinav2203/codeflow-store/checkpoint/reasoning";
+import { loadReasoningForRun, loadReasoningForProject } from "@abhinav2203/codeflow-store/reasoning";
+
+export type BranchReasoningSnapshot = {
+  runId: string;
+  projectName: string;
+  checkpoints: ReasoningCheckpoint[];
+  savedAt: string;
+};
+
+/**
+ * Snapshot reasoning checkpoints at branch creation time.
+ * Call this when creating a branch to preserve the agent's decision context.
+ *
+ * Usage:
+ *   const reasoning = await snapshotBranchReasoning(runId, projectName);
+ *   // reasoning attached to GraphBranch.metadata.reasoning
+ */
+export const snapshotBranchReasoning = async (
+  runId: string,
+  projectName: string
+): Promise<BranchReasoningSnapshot> => {
+  const checkpoints = await loadReasoningForRun(runId, projectName);
+  return {
+    runId,
+    projectName,
+    checkpoints,
+    savedAt: new Date().toISOString()
+  };
+};
+
+/**
+ * Load all reasoning snapshots across all runs for a project.
+ * Useful for auditing which runs influenced which branches.
+ */
+export const loadBranchReasoningHistory = async (
+  projectName: string
+): Promise<BranchReasoningSnapshot[]> => {
+  const summaries = await loadReasoningForProject(projectName);
+  return summaries.map(({ runId, projectName: pn, checkpoints }) => ({
+    runId,
+    projectName: pn,
+    checkpoints,
+    savedAt: checkpoints[checkpoints.length - 1]?.savedAt ?? new Date().toISOString()
+  }));
+};
+
+/**
+ * Summarize reasoning content for a branch as a readable string.
+ * Used by the CodeRAG search module to build retrieval queries.
+ */
+export const summarizeReasoningForBranch = (
+  snapshot: BranchReasoningSnapshot
+): string => {
+  if (!snapshot.checkpoints.length) {
+    return `Branch ${snapshot.runId}: No reasoning checkpoints recorded.`;
+  }
+  const lines = [
+    `Reasoning snapshot for run ${snapshot.runId} (${snapshot.checkpoints.length} checkpoints):`
+  ];
+  for (const cp of snapshot.checkpoints) {
+    lines.push(`\n--- Task: ${cp.taskId} ---`);
+    lines.push(cp.content.slice(0, 500));
+  }
+  return lines.join("\n");
+};
+```
+
+- [ ] **Step 3.2: Run check**
+
+Run: `cd packages/codeflow-versioning && npm run check`
+Expected: No TypeScript errors
+
+- [ ] **Step 3.3: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add src/reasoning/index.ts
+git commit -m "feat(versioning): add reasoning checkpoint snapshot integration"
+```
+
+---
+
+## Step 4 β€” Move API routes β†’ `./invoke`
+
+- [ ] **Step 4.1: Create `packages/codeflow-versioning/src/invoke.ts`**
+
+Consolidate all three route files into a single invoke module. This replaces the Next.js route handlers with plain async functions callable without Next.js.
+
+```typescript
+// GET /branches?projectName=xxx
+export const listBranches = async (projectName: string): Promise<GraphBranch[]>
+
+// POST /branches
+export const createBranch = async (payload: {
+  graph: BlueprintGraph
+  name: string
+  description?: string
+  parentBranchId?: string
+  runId?: string          // NEW in v0.2.0: optionally snapshot reasoning
+}): Promise<GraphBranch>
+
+// GET /branches/:id?projectName=xxx
+export const getBranch = async (
+  projectName: string,
+  branchId: string
+): Promise<GraphBranch | null>
+
+// DELETE /branches/:id?projectName=xxx
+export const removeBranch = async (projectName: string, branchId: string): Promise<void>
+```
+
+For `createBranch`:
+- Accept the same Zod schema as `src/app/api/branches/route.ts`
+- Call `createBranch` from `./branch.ts`
+- Call `saveBranch` from `./store.ts`
+- **NEW in v0.2.0**: If `runId` is provided, call `snapshotBranchReasoning(runId, projectName)` and attach the snapshot to `branch.metadata.reasoning`
+- Return the created `GraphBranch`
+
+For `listBranches`:
+- Accept `projectName: string`
+- Call `loadBranches` from `./store.ts`
+- Return `GraphBranch[]`
+
+For `getBranch`:
+- Accept `projectName` and `branchId` (validate with same regex as original route)
+- Call `loadBranch` from `./store.ts`
+- Return `null` if not found
+
+For `removeBranch`:
+- Accept `projectName` and `branchId` (validate with same regex)
+- Call `deleteBranch` from `./store.ts`
+
+- [ ] **Step 4.2: Create `packages/codeflow-versioning/src/diff.ts`**
+
+```typescript
+export const computeDiff = async (payload: {
+  baseGraph: BlueprintGraph
+  compareGraph: BlueprintGraph
+  baseId?: string
+  compareId?: string
+}): Promise<BranchDiff>
+```
+
+- Call `diffBranches` from `./branch.ts`
+- Return the `BranchDiff` result
+
+- [ ] **Step 4.3: Run check**
+
+Run: `cd packages/codeflow-versioning && npm run check`
+Expected: No TypeScript errors
+
+- [ ] **Step 4.4: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add src/invoke.ts src/diff.ts
+git commit -m "feat(versioning): move API routes to invoke module"
+```
+
+---
+
+## Step 5 β€” CodeRAG Integration (NEW)
+
+This is the core differentiator. CodeRAG lets you query branches by *what they do*, not just by name/date, and explains diffs in natural language.
+
+### Step 5.1 β€” Core CodeRAG wrapper
+
+- [ ] **Create `packages/codeflow-versioning/src/coderag/index.ts`**
+
+Adapts `src/lib/coderag.ts` for use in the versioning package. Since `@abhinav2203/coderag` is a runtime dependency, not just a dev dependency, we wrap it here.
+
+```typescript
+import path from "node:path";
+import {
+  CodeRag,
+  createCodeRag,
+  loadSerializableConfig,
+  resolveRuntimeConfig
+} from "@abhinav2203/coderag";
+import { branchDirForProject } from "@abhinav2203/codeflow-store/shared";
+
+let instance: CodeRag | null = null;
+
+export interface CodeRagConfig {
+  projectName: string;
+  repoPath: string;
+  docsPath?: string;
+  embeddingProvider?: "local-hash" | "openai" | "gemini";
+}
+
+export async function initCodeRagForProject(config: CodeRagConfig): Promise<CodeRag> {
+  const { projectName, repoPath, docsPath, embeddingProvider = "local-hash" } = config;
+  const resolvedRepoPath = path.resolve(repoPath);
+  const resolvedDocsPath = docsPath ? path.resolve(docsPath) : undefined;
+  const storageRoot = path.join(branchDirForProject(projectName), ".coderag");
+  const serializableConfig = await loadSerializableConfig(process.cwd(), undefined);
+
+  serializableConfig.repoPath = resolvedRepoPath;
+  serializableConfig.storageRoot = storageRoot;
+  serializableConfig.docsPath = resolvedDocsPath;
+  serializableConfig.embedding.provider = embeddingProvider;
+
+  const runtimeConfig = resolveRuntimeConfig(serializableConfig, process.cwd());
+
+  if (instance) {
+    await instance.close().catch(() => undefined);
+  }
+
+  instance = createCodeRag(runtimeConfig);
+  await instance.index({ docsPath: resolvedDocsPath });
+  return instance;
+}
+
+export function getCodeRagInstance(): CodeRag | null {
+  return instance;
+}
+
+export async function closeCodeRagInstance(): Promise<void> {
+  if (instance) {
+    await instance.close();
+    instance = null;
+  }
+}
+```
+
+### Step 5.2 β€” Agent retrieval utilities
+
+- [ ] **Create `packages/codeflow-versioning/src/coderag/agent.ts`**
+
+Adapts `src/lib/coderag-agent.ts`. Key changes:
+- Import `getCodeRagInstance` from `./index.ts` instead of `getCodeRag` from `@/lib/coderag`
+- Remove any Next.js-specific references
+
+```typescript
+import type { QueryResult, RetrievedNodeContext } from "@abhinav2203/coderag";
+import type { BlueprintNode } from "@abhinav2203/codeflow-core/schema";
+import { getCodeRagInstance } from "./index.js";
+
+export const buildAgentRetrievalQuery = ({ node, relatedNodes, instruction }: ...) => { ... }
+export const formatAgentRetrievalPrompt = (result: QueryResult) => { ... }
+export const resolveAgentRetrievalContext = async ({ node, relatedNodes, ... }: ...) => { ... }
+```
+
+See `src/lib/coderag-agent.ts` for full implementation β€” copy verbatim with the single import swap noted above.
+
+### Step 5.3 β€” Semantic branch search and diff explanation (NEW)
+
+> **Bug fix required:** In `formatStructuralDiff`, the last conditional reads `if (focusOn === "edges" || focusOn === "edges")` β€” change the second `"edges"` to `"nodes"`.
+
+This is the killer feature: use CodeRAG to search branches semantically and explain diffs.
+
+- [ ] **Create `packages/codeflow-versioning/src/coderag/search.ts`**
+
+```typescript
+import type { QueryResult } from "@abhinav2203/coderag";
+import type { GraphBranch, BranchDiff, BlueprintNode } from "@abhinav2203/codeflow-core/schema";
+import { getCodeRagInstance } from "./index.js";
+import { loadBranches } from "../store.js";
+import { diffBranches } from "../branch.js";

+ *   const results = await searchBranches({ projectName: "my-app", query: "authentication refactor" });
+ */
+export const searchBranches = async ({
+  projectName,
+  query,
+  limit = 5
+}: {
+  projectName: string;
+  query: string;
+  limit?: number;
+}): Promise<BranchSearchResult[]> => {
+  const codeRag = getCodeRagInstance();

+
+## Step 6 β€” Wire Next.js app to import from package
+
+> **Bug fix required:** Step 6.2 (`[id]/route.ts`) β€” `getBranch` and `removeBranch` are in `invoke.ts`, NOT `./branch.ts`. The import must be from `@abhinav2203/codeflow-versioning` (barrel) or from `./invoke`. Do NOT import from `./branch`.
+
+- [ ] **Step 6.1: Replace `src/app/api/branches/route.ts`** with:
+
+```typescript
+import { createBranch, listBranches } from "@abhinav2203/codeflow-versioning/branch";
+import { saveBranch, loadBranches } from "@abhinav2203/codeflow-versioning/store";

+      { error: error instanceof Error ? error.message : "Failed to create branch." },
+      { status: 400 }
+    );
+  }
+}
+```
+
+- [ ] **Step 6.2: Replace `src/app/api/branches/[id]/route.ts`** with:
+
+```typescript
+import { getBranch, removeBranch } from "@abhinav2203/codeflow-versioning/branch";
+import { loadBranch, deleteBranch } from "@abhinav2203/codeflow-versioning/store";
+
+// GET /branches/:id
+export async function GET(...) { ... }
+
+// DELETE /branches/:id
+export async function DELETE(...) { ... }
+```
+
+- [ ] **Step 6.3: Replace `src/app/api/branches/diff/route.ts`** with:
+
+```typescript

+## Step 7 β€” Add MCP tools
+
+- [ ] **Step 7.1: Create `packages/codeflow-versioning/src/tools.ts`**
+
+Register these tools in the MCP registry:
+
+```typescript
+// tool: versioning_branch_list

+// returns: { branches: GraphBranch[] }
+
+// tool: versioning_branch_create
+// args: { projectName: string, graph: BlueprintGraph, name: string, description?: string, parentBranchId?: string, runId?: string }
+// returns: { branch: GraphBranch }
+
+// tool: versioning_branch_get
+// args: { projectName: string, branchId: string }
+// returns: { branch: GraphBranch } | { error: string }
+
+// tool: versioning_branch_delete
+// args: { projectName: string, branchId: string }
+// returns: { deleted: true }
+
+// tool: versioning_diff
+// args: { baseGraph: BlueprintGraph, compareGraph: BlueprintGraph, baseId?: string, compareId?: string }
+// returns: { diff: BranchDiff }
+
+// tool: versioning_reasoning_snapshot
+// args: { projectName: string, runId: string }
+// returns: { snapshot: BranchReasoningSnapshot }
+
+// tool: versioning_branch_search   // NEW v0.2.0
+// args: { projectName: string, query: string, limit?: number }
+// returns: { results: BranchSearchResult[] }
+
+// tool: versioning_explain_diff     // NEW v0.2.0
+// args: { baseBranch: GraphBranch, compareBranch: GraphBranch, focusOn?: "nodes" | "edges" | "reasoning" }
+// returns: { explanation: string }
+```
+
+- [ ] **Step 7.2: Register tools in `codeflow-mcp`**
+
+In `packages/codeflow-mcp/src/tools.ts`, add:
+
+```typescript
+import { versioningTools } from "@abhinav2203/codeflow-versioning/tools";
+
+// Merge into existing tools registry
+export const allTools = [...baseTools, ...versioningTools];
+```
+
+- [ ] **Step 7.3: Run check and tests**
+
+Run: `cd packages/codeflow-versioning && npm run check && npm run test`
+Expected: Both pass
+
+- [ ] **Step 7.4: Commit**
+
+```bash
+cd packages/codeflow-versioning
+git add src/tools.ts
+git commit -m "feat(versioning): add MCP tools for branch and diff operations"
+```
+

+
+## Step 8 β€” Final verification
+
+- [ ] **Step 8.1: Run all package checks**
+
+Run: `cd packages/codeflow-versioning && npm run check && npm run test && npm run build`
+Expected: `tsc --noEmit` passes, `vitest run` passes, build produces `dist/` with all entry points
+
+- [ ] **Step 8.2: Verify app still works**
+
+Run: `cd /Users/abhinavnehra/git/CodeFlow && npm run check`
+Expected: App type-checks with the rewired routes

+## What each codeflow-store module contributes to versioning
+
+| Module | Used in versioning for |
+|--------|-----------------------|
+| `./branch` | Persistence for `GraphBranch` JSON files |
+| `./reasoning` | Snapshot and load reasoning checkpoints at branch time |
+| `./checkpoint/reasoning` | Fine-grained checkpoint save/load within reasoning snapshots |
+| `./observability` | Optionally attach observability snapshot to branch metadata |
+| `./risk` | Optionally attach risk report to branch metadata |
+
+---
+
+## Bug register β€” fix during implementation
+
+| # | File | Bug | Fix |
+|---|------|-----|-----|
+| 1 | `coderag/search.ts` (`formatStructuralDiff`) | `if (focusOn === "edges" \|\| focusOn === "edges")` β€” second operand is redundant | Change second `"edges"` to `"nodes"` |
+| 2 | `src/app/api/branches/[id]/route.ts` (Step 6.2) | Imports `getBranch`/`removeBranch` from `"./branch"` | Import from `@abhinav2203/codeflow-versioning` (barrel) or from `./invoke` |
+
+---
+
+## Key design decisions
+
+1. **`coderag` is a runtime dependency, not just dev** β€” The package actually calls `createCodeRag()` and `codeRag.query()`. It's listed in `dependencies` (with a version ceiling).
+
+2. **CodeRAG singleton is scoped to the versioning package** β€” `getCodeRagInstance()` is a module-level singleton. The app initializes it via `initCodeRagForProject()` before using search/explain tools.
+
+3. **Graceful degradation** β€” If CodeRAG is not initialized, `searchBranches` falls back to keyword matching and `explainBranchDiff` returns a structural diff. No hard failures.
+
+4. **`runId` is optional in `createBranch`** β€” Reasoning snapshots are only captured if `runId` is provided. This avoids breaking existing callers that don't pass `runId`.
+
+5. **No new schema types** β€” `BranchReasoningSnapshot` is defined in TypeScript only; it doesn't need a Zod schema because it's an internal shape constructed by the package, not parsed from external input.

+# codeflow-versioning 0.3.0 Implementation Plan
+
+> **For agentic workers:** Use `superpowers:subagent-driven-development` or `superpowers:executing-plans`. Steps use checkbox syntax for tracking.
+
+**Goal:** Wire all codeflow-store modules into codeflow-versioning's branch metadata, expose them to CodeRAG for cross-artifact search, and make the full agentic memory queryable from a single interface.
+
+**The core idea:** codeflow-store produces structured artifacts (reasoning checkpoints, observability spans/logs, risk reports, run records, sessions). codeflow-versioning creates branches. CodeRAG indexes all of it. The result: one semantic search interface across branches, agent reasoning, execution traces, and risk decisions.
+
+---
+
+## What each module contributes
+
+| codeflow-store module | What it is | What it adds to versioning |
+|----------------------|------------|---------------------------|
+| `./reasoning` | `ReasoningCheckpoint[]` per run | Agent thinking at decision time |
+| `./checkpoint/reasoning` | Fine-grained task-level checkpoints | Individual task reasoning |
+| `./observability` | `ObservabilitySnapshot` (spans + logs) | Execution trace |
+| `./risk` | `RiskReport` (score + factors) | What the agent flagged as risky |
+| `./run` | `RunRecord` | Execution summary |
+| `./approval` | `ApprovalRecord` | Human approval decisions |
+| `./session` | `PersistedSession` (graph + plan + reports) | Full run state |
+

+
+```typescript

+    spans,
+    logs,
+    graph: branch.graph
+  });
+};
+```
+
+### Step 1.2 β€” `src/risk.ts`
+
+```typescript
+import type { RiskReport } from "@abhinav2203/codeflow-core/schema";
+import { assessExportRisk } from "@abhinav2203/codeflow-store/risk";
+import type { BlueprintGraph, RunPlan } from "@abhinav2203/codeflow-core/schema";

+
+### Step 1.4 β€” Update `src/invoke.ts`
+
+Update `createBranch` to accept optional flags and attach all artifacts:

+  outputDir?: string;              // NEW v0.3.0: used with attachRisk

+git commit -m "feat(versioning): wire observability, risk, and session snapshots to branch creation"
+```
+
+---
+
+## Step 2 β€” CodeRAG integration for observability and risk
+
+### Step 2.1 β€” `src/coderag/observability.ts`
+
+Indexes observability data in CodeRAG and provides search/explain.
+
+```typescript
+import type { ObservabilitySnapshot, TraceSpan, ObservabilityLog } from "@abhinav2203/codeflow-core/schema";

+git commit -m "feat(versioning): add CodeRAG-powered observability and risk search"
+```
+
+---
+
+## Step 3 β€” Update MCP tools
+
+Add new tools to `src/tools.ts`:
+
+```typescript

+  "Explain the execution observability attached to a branch.",

+
+Also update `versioning_branch_create` tool description to reflect the new options.
+
+### Step 3.2 β€” Commit
+
+```bash
+cd packages/codeflow-versioning
+git add src/tools.ts
+git commit -m "feat(versioning): add observability and risk MCP tools"
+```
+
+---
+
+## Step 4 β€” Final verification
+

+cd /Users/abhinavnehra/git/CodeFlow && npm run check
+```
+
+---
+
+## Full capability inventory after v0.3.0
+
+### Query by...
+
+| What | How |
+|------|-----|
+| Branch name/description | `searchBranches` (keyword or CodeRAG) |
+| What nodes/responsibilities a branch handles | CodeRAG semantic over branch graph |
+| Agent reasoning at branch creation | `loadBranchReasoningHistory` |
+| Full execution trace (spans + logs) | `explainBranchObservability` |
+| Which branches had execution errors | `searchObservability` |
+| Risk profile of a branch | `explainBranchRisk` |
+| Branches by risk score/factors | `searchBranchesByRisk` |
+| Which branches got human approval | stored in `branch.metadata.session.approvalIds` |
+| Diff between two branches | `computeDiff` + `explainBranchDiff` |
+| Natural language about any branch | `explainBranchDiff` with CodeRAG |
+
+### Agent workflow with v0.3.0
+
+```
+Agent starts work
+  β†’ createBranch({ attachObservability: true, attachRisk: true, attachSession: true, runId, runPlan })
+  β†’ Branch created with:
+      - graph snapshot
+      - reasoning checkpoints from this run
+      - observability snapshot (spans + logs)
+      - risk report
+      - session snapshot
+  β†’ Agent works, periodically snapshots reasoning via saveTaskReasoningCheckpoint
+  β†’ Agent calls explainBranchDiff or searchBranchesByRisk to review work
+  β†’ User approves β†’ branch merged + approval record attached
+  β†’ Later: searchBranches("auth refactor with security concerns and low risk")
+      β†’ CodeRAG finds branches matching description + reasoning content + risk profile
+      β†’ Returns ranked results with full context
+```
+
+---
+
+## What CodeRAG indexes that it didn't before
+
+| Content | Indexed by | Used for |
+|---------|-----------|---------|
+| `branch.metadata.reasoning` | Text in branch doc | "which branch had reasoning about X" |
+| `branch.metadata.observability` | Text in observability doc | "which branch had errors during execution" |
+| `branch.metadata.risk` | Text in risk doc | "which branch was flagged as high risk for X" |
+| `branch.metadata.session` | Text in session doc | "which branch was created from a session with Y characteristics" |
+
+Each of these is serialized as a text document (or set of docs) and indexed alongside the codebase. CodeRAG's existing `index()` method handles this β€” we just call it with the right content.
+
+---
+
+## Key design decisions
+
+1. **`attachObservability/Risk/Session` are all opt-in** β€” No new behavior unless explicitly requested in `createBranch`. Existing callers are unaffected.
+
+2. **Observability is stored as a snapshot, not streamed** β€” `ObservabilitySnapshot` is a point-in-time capture. Branch receives whatever was in the snapshot at creation time. Future executions aren't automatically merged β€” use `mergeBranchObservability` to update.
+
+3. **Risk requires `runPlan`** β€” Can't compute a risk report without knowing the execution plan. `runPlan` is passed alongside `attachRisk: true`. The risk is computed fresh at branch creation time (from `assessExportRisk`), so it reflects the plan that was used to create the branch.
+
+4. **CodeRAG graceful degradation** β€” All search functions check `getCodeRagInstance()` and fall back to filtered in-memory search or return empty results if CodeRAG is not initialized. No hard failures.
+
+5. **Metadata shape** β€” All attached data lives in `branch.metadata.{reasoning, observability, risk, session}`. The `GraphBranch` type in `codeflow-core` doesn't have a `metadata` field β€” we cast with `as any`. In a future `codeflow-core` schema update, `metadata` should be formally typed as `Record<string, unknown>`.

+# Developer Prompt β€” `codeflow-versioning` v0.2.0 Full Implementation
+
+> This is the canonical prompt to hand to a developer agent (or run yourself) for the complete implementation of the `codeflow-versioning` npm package. Follow the phases in order. Fix the bugs noted in each phase before proceeding to the next.
+
+---
+
+## Context
+
+You are building `@abhinav2203/codeflow-versioning` v0.2.0 β€” a standalone npm package that extracts blueprint branching, diff, and reasoning-snapshot functionality from a Next.js app into a reusable package with deep CodeRAG integration.
+
+**Tech stack:** TypeScript, Node.js, `zod`, `vitest`, `uuid`, `@abhinav2203/codeflow-core`, `@abhinav2203/codeflow-store`, `@abhinav2203/coderag`
+
+**Package location:** `packages/codeflow-versioning/`
+
+**Key prior art (read these files first):**
+- `src/lib/blueprint/branches.ts` β€” source for `createBranch` and `diffBranches`
+- `src/lib/blueprint/branch-store.ts` β€” source for store persistence (already re-exported by `codeflow-store/branch`)
+- `src/app/api/branches/route.ts` β€” source for invoke logic
+- `src/app/api/branches/[id]/route.ts` β€” source for get/remove logic
+- `src/app/api/branches/diff/route.ts` β€” source for diff logic
+- `src/lib/coderag.ts` β€” source for CodeRAG initialization
+- `src/lib/coderag-agent.ts` β€” source for CodeRAG agent utilities
+- `packages/codeflow-store/src/branch/index.ts` β€” re-export from here
+- `packages/codeflow-store/src/reasoning/index.ts` β€” re-export from here
+- `packages/codeflow-store/src/checkpoint/reasoning.ts` β€” re-export from here
+- `node_modules/@abhinav2203/coderag/dist/types.d.ts` β€” CodeRAG TypeScript types
+
+**Schema sources (import from `@abhinav2203/codeflow-core/schema`, do not copy):**
+- `GraphBranch`, `BranchDiff`, `NodeDiff`, `EdgeDiff`, `BlueprintGraph`, `BlueprintNode`, `ObservabilitySnapshot`, `ReasoningCheckpoint`
+
+**Store paths (import from `@abhinav2203/codeflow-store/shared`, do not copy):**
+- `branchDirForProject`, `branchPath`, `reasoningCheckpointDir`, `reasoningBasePath`
+
+**Known bugs to fix during implementation:**
+1. `formatStructuralDiff` in `coderag/search.ts` β€” duplicate condition: `if (focusOn === "edges" || focusOn === "edges")` β€” change second `"edges"` to `"nodes"`
+2. Step 6.2 import path β€” `getBranch`/`removeBranch` live in `invoke.ts`, not `./branch.ts` β€” import from the barrel `index.ts`
+
+---
+
+## PHASE 0 β€” Scaffold
+
+Create the package skeleton. All steps are sequential.
+
+### Step 0.1 β€” Create directory structure
+
+```bash
+mkdir -p packages/codeflow-versioning/src/coderag
+mkdir -p packages/codeflow-versioning/test-fixtures
+```
+
+### Step 0.2 β€” Create `packages/codeflow-versioning/package.json`
+
+```json
+{
+  "name": "@abhinav2203/codeflow-versioning",
+  "version": "0.2.0",
+  "private": true,
+  "type": "module",
+  "main": "./dist/index.js",
+  "types": "./dist/index.d.ts",
+  "exports": {
+    ".": { "types": "./dist/index.d.ts", "default": "./dist/index.js" },
+    "./branch": { "types": "./dist/branch/index.d.ts", "default": "./dist/branch/index.js" },
+    "./store": { "types": "./dist/store/index.d.ts", "default": "./dist/store/index.js" },
+    "./reasoning": { "types": "./dist/reasoning/index.d.ts", "default": "./dist/reasoning/index.js" },
+    "./coderag": { "types": "./dist/coderag/index.d.ts", "default": "./dist/coderag/index.js" }
+  },
+  "scripts": {
+    "check": "tsc --noEmit",
+    "test": "vitest run",
+    "build": "tsc --outDir dist --declaration --declarationMap",
+    "clean": "rm -rf dist"
+  },
+  "dependencies": {
+    "@abhinav2203/codeflow-core": "workspace:*",
+    "@abhinav2203/codeflow-store": "workspace:*",
+    "@abhinav2203/coderag": "^0.2.1",
+    "uuid": "^11.0.0",
+    "zod": "^3.0.0"
+  },
+  "devDependencies": {
+    "@types/node": "^22.0.0",
+    "@types/uuid": "^10.0.0",
+    "typescript": "^5.7.0",
+    "vitest": "^3.0.0"
+  }
+}
+```
+
+### Step 0.3 β€” Create `packages/codeflow-versioning/tsconfig.json`
+
+```json
+{
+  "extends": "../../../tsconfig.json",
+  "compilerOptions": {
+    "outDir": "./dist",
+    "rootDir": "./src"
+  },
+  "include": ["src"]
+}
+```
+
+### Step 0.4 β€” Create `packages/codeflow-versioning/vitest.config.ts`
+
+```typescript
+import { defineConfig } from "vitest/config";
+
+export default defineConfig({
+  test: {
+    environment: "node",
+    include: ["src/**/*.test.ts"]
+  }
+});
+```
+
+### Step 0.5 β€” Install dependencies
+
+```bash
+cd packages/codeflow-versioning && npm install
+```
+
+### Step 0.6 β€” Commit
+
+```bash
+cd packages/codeflow-versioning
+git add package.json tsconfig.json vitest.config.ts
+git commit -m "feat(versioning): scaffold package skeleton v0.2.0"
+```
+
+---
+
+## PHASE 1 β€” Core modules (Steps 1, 2, 3 run in parallel)
+
+### Step 1 β€” `src/branch/index.ts` β€” createBranch + diffBranches
+
+**File:** `packages/codeflow-versioning/src/branch/index.ts`
+
+Copy the logic from `src/lib/blueprint/branches.ts` with these changes:
+- Replace `import crypto from "node:crypto"` with `import { v4 as uuidv4 } from "uuid"`
+- Replace `createBranchId()` body: `return crypto.randomUUID()` β†’ `return uuidv4()`
+- Replace all `@/lib/blueprint/schema` imports with `@abhinav2203/codeflow-core/schema`
+- Keep the Zod schemas (`blueprintGraphSchema`) from `@abhinav2203/codeflow-core/schema`
+- The `edgeIncidenceCache` WeakMap and all helper functions (`nodeKey`, `edgeKey`, `getEdgeIncidenceMap`, `countImpactedEdges`) stay inline β€” they are private to this module
+- Export: `createBranchId`, `createBranch`, `diffBranches`
+
+**Signatures:**
+```typescript
+export const createBranchId = (): string => uuidv4();
+
+export const createBranch = ({
+  graph,
+  name,
+  description,
+  parentBranchId
+}: {
+  graph: BlueprintGraph;
+  name: string;
+  description?: string;
+  parentBranchId?: string;
+}): GraphBranch
+
+export const diffBranches = (
+  base: BlueprintGraph,
+  compare: BlueprintGraph,
+  baseId?: string,
+  compareId?: string
+): BranchDiff
+```
+
+**Run check:** `cd packages/codeflow-versioning && npm run check`
+**Run tests:** `cd packages/codeflow-versioning && npm run test`
+
+**Commit:**
+```bash
+cd packages/codeflow-versioning
+git add src/branch/index.ts
+git commit -m "feat(versioning): move createBranch and diffBranches to branch module"
+```
+
+---
+
+### Step 2 β€” `src/store/index.ts` β€” re-export from codeflow-store
+
+**File:** `packages/codeflow-versioning/src/store/index.ts`
+
+This module re-exports persistence functions from `codeflow-store/branch`. No copy needed.
+
+```typescript
+// Re-export save/load/delete from @abhinav2203/codeflow-store/branch
+export {
+  saveBranch,
+  loadBranch,
+  loadBranches,
+  deleteBranch
+} from "@abhinav2203/codeflow-store/branch";
+```
+
+**Run check:** `cd packages/codeflow-versioning && npm run check`
+
+**Commit:**
+```bash
+cd packages/codeflow-versioning
+git add src/store/index.ts
+git commit -m "feat(versioning): re-export branch store from codeflow-store"
+```
+
+---
+
+### Step 3 β€” `src/reasoning/index.ts` β€” reasoning checkpoint snapshots (NEW)
+
+**File:** `packages/codeflow-versioning/src/reasoning/index.ts`
+
+This module attaches reasoning checkpoint context to branches at creation time. It imports from `codeflow-store/reasoning` and `codeflow-store/checkpoint/reasoning`.
+
+```typescript
+import type { ReasoningCheckpoint } from "@abhinav2203/codeflow-store/checkpoint/reasoning";
+import {
+  loadReasoningForRun,
+  loadReasoningForProject
+} from "@abhinav2203/codeflow-store/reasoning";
+
+/**
+ * A reasoning snapshot captured at branch creation time.
+ */
+export type BranchReasoningSnapshot = {
+  runId: string;
+  projectName: string;
+  checkpoints: ReasoningCheckpoint[];
+  savedAt: string;
+};
+
+/**
+ * Snapshot all reasoning checkpoints for a given run and project.
+ * Call this when creating a branch to preserve the agent's decision context.
+ *
+ * @example
+ * const reasoning = await snapshotBranchReasoning(runId, projectName);
+ * // attach reasoning to branch.metadata.reasoning
+ */
+export const snapshotBranchReasoning = async (
+  runId: string,
+  projectName: string
+): Promise<BranchReasoningSnapshot> => {

+
+### Step 5 β€” CodeRAG Integration (three files)
+
+#### Step 5.1 β€” `src/coderag/index.ts` β€” CodeRAG init + singleton
+
+**File:** `packages/codeflow-versioning/src/coderag/index.ts`
+
+Adapts `src/lib/coderag.ts` for the versioning package. Key change: uses `branchDirForProject` from `codeflow-store/shared` as the storage root.
+
+```typescript
+import path from "node:path";
+
+import {
+  CodeRag,
+  createCodeRag,
+  loadSerializableConfig,
+  resolveRuntimeConfig
+} from "@abhinav2203/coderag";
+import { branchDirForProject } from "@abhinav2203/codeflow-store/shared";
+
+let instance: CodeRag | null = null;
+
+export interface CodeRagConfig {
+  projectName: string;
+  repoPath: string;
+  docsPath?: string;
+  embeddingProvider?: "local-hash" | "gemini";
+}
+
+/**
+ * Initialize CodeRAG for a project. Call once before using search/explain.
+ */
+export const initCodeRagForProject = async (config: CodeRagConfig): Promise<CodeRag> => {
+  const { projectName, repoPath, docsPath, embeddingProvider = "local-hash" } = config;
+  const resolvedRepoPath = path.resolve(repoPath);
+  const resolvedDocsPath = docsPath ? path.resolve(docsPath) : undefined;
+  const storageRoot = path.join(branchDirForProject(projectName), ".coderag");
+
+  const serializableConfig = await loadSerializableConfig(process.cwd(), undefined);
+  serializableConfig.repoPath = resolvedRepoPath;
+  serializableConfig.storageRoot = storageRoot;
+  serializableConfig.docsPath = resolvedDocsPath;
+  serializableConfig.embedding.provider = embeddingProvider;
+
+  const runtimeConfig = resolveRuntimeConfig(serializableConfig, process.cwd());
+
+  if (instance) {
+    await instance.close().catch(() => undefined);
+  }
+
+  instance = createCodeRag(runtimeConfig);
+  await instance.index({ docsPath: resolvedDocsPath });
+  return instance;
+};
+
+export const getCodeRagInstance = (): CodeRag | null => instance;
+
+export const closeCodeRagInstance = async (): Promise<void> => {
+  if (instance) {
+    await instance.close();
+    instance = null;
+  }
+};
+```
+
+#### Step 5.2 β€” `src/coderag/agent.ts` β€” CodeRAG agent utilities
+
+**File:** `packages/codeflow-versioning/src/coderag/agent.ts`
+
+Copy from `src/lib/coderag-agent.ts` with **one change**: replace `import { getCodeRag } from "@/lib/coderag"` with `import { getCodeRagInstance } from "./index.js"`.
+
+Also replace the function name `getCodeRag` β†’ `getCodeRagInstance` throughout the body wherever it appears (the `resolveAgentRetrievalContext` function calls it).
+
+All other logic remains identical:
+- `buildAgentRetrievalQuery` β€” builds a query string from node + related nodes + instruction
+- `formatAgentRetrievalPrompt` β€” formats a QueryResult as a readable prompt string
+- `formatAgentRetrievalNote` β€” formats retrieval context as a short note string
+- `resolveAgentRetrievalContext` β€” performs the actual CodeRAG query and returns context
+- `AgentRetrievalContext` type
+- All helper functions: `clampDepth`, `compactList`, `lineRangeLabel`, `createExcerpt`, `formatRetrievedNode`
+
+#### Step 5.3 β€” `src/coderag/search.ts` β€” Semantic branch search + diff explanation (NEW)
+
+**File:** `packages/codeflow-versioning/src/coderag/search.ts`
+
+This is the killer feature. Two public functions:
+
+**`searchBranches`** β€” natural language search across all branches:
+```typescript
+export const searchBranches = async ({
+  projectName,
+  query,
+  limit = 5
+}: {
+  projectName: string;
+  query: string;
+  limit?: number;
+}): Promise<BranchSearchResult[]>
+```
+
+**`explainBranchDiff`** β€” CodeRAG-powered natural language diff explanation:
+```typescript
+export const explainBranchDiff = async ({
+  baseBranch,
+  compareBranch,
+  focusOn = "nodes"
+}: {
+  baseBranch: GraphBranch;
+  compareBranch: GraphBranch;
+  focusOn?: "nodes" | "edges" | "reasoning";
+}): Promise<string>
+```
+
+Full implementation:
+
+```typescript
+import type { QueryResult } from "@abhinav2203/coderag";
+import type { GraphBranch, BranchDiff, BlueprintNode } from "@abhinav2203/codeflow-core/schema";
+import { getCodeRagInstance } from "./index.js";
+import { loadBranches } from "../store/index.js";

+
+**IMPORTANT bug fix:** The last conditional in `formatStructuralDiff` has `|| focusOn === "edges"` duplicated β€” change the second one to `|| focusOn === "nodes"`. The corrected line is:

+
+## PHASE 3 β€” Wiring (Steps 6 and 7 are sequential)
+
+### Step 6 β€” Wire Next.js app to import from package
+
+Replace the three route files with thin re-exports from the package. **Note:** `getBranch` and `removeBranch` must be imported from the package root (`@abhinav2203/codeflow-versioning`) or from `invoke.ts` β€” NOT from `./branch`. The Project Shepherd identified this as a bug in the original plan.

+```
+Expected: `tsc --noEmit` passes, `vitest run` passes, build produces `dist/` with all entry points.
+
+### Step 8.2 β€” Verify app still type-checks
+
+```bash
+cd /Users/abhinavnehra/git/CodeFlow && npm run check

+# codeflow-agent Package Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use `superpowers:subagent-driven-development` (recommended) or `superpowers:executing-plans` to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Create `codeflow-agent` package - an orchestration layer for subagent-driven development that spawns specialized Claude Code agents for each implementation task using the Agent tool.
+
+**Architecture:** The agent package acts as a task dispatcher that:
+1. Reads implementation tasks from a plan
+2. Spawns fresh specialized subagents per task using Claude Code's `Agent` tool
+3. Coordinates task dependencies and sequential execution
+4. Aggregates results and handles errors
+
+**Tech Stack:** TypeScript, Node.js, Claude Code Agent tool, @abhinav2203/codeflow-store, @abhinav2203/codeflow-core

+# codeflow-agent
+
+Orchestration layer for subagent-driven development using Claude Code agents.
+
+## Overview
+
+`codeflow-agent` is a task orchestration package that spawns specialized Claude Code subagents to execute implementation tasks in parallel. It provides:
+
+- **Task Queue Management** - Handles task dependencies and parallel execution
+- **Agent Spawning** - Spawns fresh subagents per task using Claude Code's Agent tool
+- **Skill Integration** - 15+ built-in skills from the superpowers plugin
+- **MCP Integration** - 6 built-in MCP servers for extended capabilities
+- **Plugin System** - 6 built-in plugins for specialized workflows
+- **Result Aggregation** - Collects and reports results from all subagents

+# codeflow-evolution Package Extraction Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Extract `@abhinav2203/codeflow-evolution` as a standalone npm package. Provides ghost node suggestions (AI + heuristic) and genetic architecture evolution. Works in isolation β€” no monorepo required.
+
+**Architecture:**
+- Core logic is a **programmatic API** β€” pure functions exported from `src/genetic/` and `src/ghost/` sub-modules
+- CLI is a **thin wrapper** β€” human-readable output by default, `--json` for machine output
+- **Pluggable LLM provider** β€” `LLMProvider` interface, NVIDIA provider as default
+- All internal deps resolved via npm (`@abhinav2203/codeflow-core`, `@abhinav2203/codeflow-agent`)
+
+**Tech Stack:** TypeScript, Node.js, `zod`, `vitest`

+# CodeFlow Phase 2 Decomposition Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Decompose 3 remaining packages from the CodeFlow monorepo into standalone npm packages that work independently outside the monorepo.
+
+**Architecture:** Three independent npm packages (`@abhinav2203/codeflow-evolution`, `@abhinav2203/codeflow-canvas`, `@abhinav2203/codeflow-dtwin`) with npm dependencies on each other and on `@abhinav2203/codeflow-core`. No monorepo imports, no git imports. Each package has CLI and/or React component + API surface.
+
+**Tech Stack:** TypeScript, Vitest, React 18, @xyflow/react, @monaco-editor/react
+
+---
+
+## Package Implementation Order
+
+```
+1. codeflow-evolution  (no dependencies on canvas or dtwin)
+2. codeflow-canvas     (depends on core, optional store/execution)
+3. codeflow-dtwin       (depends on canvas + execution)

+## Skills to Use per Task
+
+| Task | Primary Skill | Secondary Skills |
+|------|---------------|------------------|
+| Genetic algorithm | `sparc:tdd` | `pr-review-toolkit:code-reviewer`, `simplify` |
+| Ghost nodes | `sparc:coder` | `sparc:documenter`, `pr-review-toolkit:code-reviewer` |
+| React components | `sparc:tester` | `frontend-design@claude-plugins-official`, `pr-review-toolkit:code-reviewer` |
+| TypeScript modules | `sparc:tdd` | `simplify`, `pr-review-toolkit:code-reviewer` |
+| Simulation engine | `sparc:tdd` | `sparc:coder`, `pr-review-toolkit:code-reviewer` |
+
+---
+
+## Verification Commands (Run After Each Package)
+
+```bash
+# 1. Type check
+cd packages/codeflow-evolution && npm run check
+cd packages/codeflow-canvas && npm run check
+cd packages/codeflow-dtwin && npm run check
+
+# 2. Tests
+cd packages/codeflow-evolution && npm test
+cd packages/codeflow-canvas && npm test
+cd packages/codeflow-dtwin && npm test
+
+# 3. Build
+cd packages/codeflow-evolution && npm run build
+cd packages/codeflow-canvas && npm run build
+cd packages/codeflow-dtwin && npm run build
+
+# 4. Isolation test (in empty dir)
+cd /tmp && mkdir test-isolation && cd test-isolation
+npm install @abhinav2203/codeflow-evolution
+npx codeflow-evolution ghost ./blueprint.json  # test actual CLI
+```
+
+---
+
+## Critical Constraints
+
+1. **NO MONOREPO IMPORTS** β€” All imports use `@abhinav2203/codeflow-*` npm packages only
+2. **NO `any` TYPES** β€” Full TypeScript strict mode
+3. **TESTS NEXT TO SOURCE** β€” Every `.ts`/`.tsx` has co-located `.test.ts`/`.test.tsx`
+4. **COMMIT AFTER EACH TASK** β€” Use conventional commits: `feat:`, `fix:`, `refactor:`, `test:`, `docs:`
+5. **NO PLACEHOLDERS** β€” Every step has complete code, no "TODO", no "TBD"
+6. **CLI AS CONTRACT** β€” If CLI works standalone, the package is correctly decomposed

+# codeflow-agent
+
+Orchestration layer for subagent-driven development using Claude Code agents.
+
+## Overview
+
+`codeflow-agent` is a task orchestration package that spawns specialized Claude Code subagents to execute implementation tasks in parallel. It provides:
+
+- **Task Queue Management** - Handles task dependencies and parallel execution
+- **Agent Spawning** - Spawns fresh subagents per task using Claude Code's Agent tool
+- **Skill Integration** - 15+ built-in skills from the superpowers plugin
+- **MCP Integration** - 6 built-in MCP servers for extended capabilities
+- **Plugin System** - 6 built-in plugins for specialized workflows
+- **Result Aggregation** - Collects and reports results from all subagents
+
+## Installation
+
+```bash
+npm install @abhinav2203/codeflow-agent
+```
+
+## Usage
+
+### CLI
+
+```bash
+# Execute a plan
+codeflow-agent --plan path/to/plan.json
+
+# List available capabilities
+codeflow-agent --list-skills
+codeflow-agent --list-mcp
+codeflow-agent --list-plugins
+```
+
+### Programmatic
+
+```typescript
+import { AgentSpawner } from '@abhinav2203/codeflow-agent';
+import type { AgentTask } from '@abhinav2203/codeflow-agent';
+
+const tasks: AgentTask[] = [
+  {
+    id: 'task-1',
+    name: 'Create user model',
+    description: 'Create the User model with email and password fields',
+    files: ['src/models/user.ts'],
+    verify: 'npm test -- --filter=user',
+    done: 'User model created with validated email and hashed password',
+    dependsOn: [],
+    skills: ['superpowers:subagent-driven-development'],
+    agentType: 'coder'
+  }
+];
+
+const spawner = new AgentSpawner({ maxConcurrent: 3 });
+const results = await spawner.executeWithQueue(tasks, async (task) => {
+  // Execute the task
+  return 'Task completed';
+});
+```

+# Phase 2 β€” Future Feature Roadmap
+
+> These items are deferred from Phase 1 (Reasoning Journal). They are not yet implemented.
+
+---
+
+## P2-1: Observability Span Linking
+
+Link trace spans to specific tasks by adding `taskId` to `TraceSpan`.
+
+**Schema change:**
+```ts
+export const traceSpanSchema = z.object({
+  name: z.string(),
+  spanId: z.string(),
+  traceId: z.string(),
+  taskId: z.string().optional(),   // NEW: links span β†’ task β†’ node
+  blueprintNodeId: z.string().optional(),
+  startTime: z.string().datetime(),
+  endTime: z.string().datetime(),
+  status: z.enum(["ok", "error", "timeout"]),
+  attributes: z.record(z.unknown()).default({})
+});
+```
+
+**What this enables:**
+- Full trace waterfall: span β†’ task β†’ node β†’ run record
+- Per-task latency breakdown
+- Filtering spans by taskType or file
+
+**Status:** Not started.
+
+---
+
+## P2-2: Ring-Buffer + Configurable Observability Caps
+
+Currently the observability module has a hard `slice(-500)` cap on all items. Phase 2 introduces configurable, per-project, ring-buffer-based eviction.
+
+**Problems with current approach:**
+- 500-item cap is too small for busy agents (50 spans/task Γ— 20 tasks = 1000 spans in one session)
+- Spans (~100-500 bytes) and logs (~1-10KB) have different storage profiles β€” same cap treats them identically
+- No per-project override
+
+**Proposed design:**
+```ts
+// Config file: storeRoot/observability/config.json
+interface ObservabilityConfig {
+  spansCap: number;      // default 500
+  logsCap: number;       // default 2000
+  mode: "ring-buffer";   // only ring-buffer for now
+}
+
+// Per-project override: storeRoot/observability/<projectName>-config.json
+// Merged on top of global config, only overrides values present in override file
+```
+
+**Implementation notes:**
+- Separate `mergeSpans` and `mergeLogs` from combined `mergeObservabilitySnapshot`
+- Ring-buffer: when cap is reached, oldest item is evicted to make room for newest
+- Keep last N items per project, not global
+
+**Status:** Not started.
+
+---
+
+## P2-3: Token Usage Tracking
+
+Add structured metadata to the reasoning field for cost and performance analysis.
+
+**Proposed reasoning extension (optional sub-fields):**
+```ts
+export const reasoningMetadataSchema = z.object({
+  tokensUsed: z.number().optional(),
+  model: z.string().optional(),
+  attempts: z.number().int().min(1).default(1),
+  latencyMs: z.number().optional()
+});
+
+// In taskExecutionResult:
+interface TaskExecutionResult {
+  taskId: string;
+  nodeId: string;
+  status: ExecutionTaskStatus;
+  reasoning: string;           // free-text (primary)
+  reasoningMetadata: reasoningMetadataSchema.optional();  // structured (optional)
+  changes: FileChange[];
+  // ...
+}
+```
+
+**What this enables:**
+- Cost per task, per project, per run
+- Performance profiling (latencyMs per taskType)
+- Retry analysis (attempts > 1 = had to retry)
+
+**Status:** Not started.
+
+---
+
+## P2-4: Crash Recovery / Write-Ahead Reasoning
+
+Currently reasoning lives in the agent's memory until `saveRunRecord` is called. If the process dies before, reasoning is lost.
+
+**Proposed:**
+- Agent writes reasoning to a lightweight checkpoint file (`runs/<runId>/<taskId>-reasoning.json`) before executing the task
+- On crash recovery, the agent reads these files and repopulates reasoning
+- This is an agent-side concern, but codeflow-store should provide the checkpoint API
+
+**API sketch:**
+```ts
+// Agent calls this before starting task work
+saveTaskReasoningCheckpoint(runId: string, taskId: string, reasoning: string, changes: FileChange[]): Promise<void>
+
+// Agent calls this after successful saveRunRecord
+clearTaskReasoningCheckpoint(runId: string, taskId: string): Promise<void>
+```
+
+**Status:** Not started. Requires agent-side integration.
+
+---
+
+## P2-5: CodeRAG Eviction Policy
+
+When run records are deleted or projects are archived, CodeRAG must be notified to remove reasoning from its index.
+
+**Questions to resolve:**
+- Who triggers the eviction β€” codeflow-store or CodeRAG?
+- Is it event-based (store emits deletion event) or polling-based (CodeRAG syncs periodically)?
+- What happens to reasoning for deleted runs β€” soft-delete with TTL, or hard-delete?
+
+**Status:** Not started. Requires CodeRAG integration contract.
+
+---
+
+## P2-6: Full LLM Response Storage (Optional)
+
+Store the raw LLM output per task, with optional compression.
+
+**Use cases:**
+- Compliance: must retain full audit trail of agent output
+- Debugging: replay exact agent context for failure investigation
+- Fine-tuning: use data to improve agent prompts
+
+**Storage approach (if needed):**
+```ts
+interface TaskLLMOutput {
+  taskId: string;
+  runId: string;
+  compressed: boolean;
+  content: string;  // raw LLM response or compressed blob
+  compression: "gzip" | "none";
+  sizeBytes: number;
+}
+```
+
+**Note:** This is the lowest-priority Phase 2 item. Only pursue if there is a specific compliance or debugging requirement. The free-text reasoning field (Phase 1) is sufficient for most reasoning documentation needs.
+
+**Status:** Not started. Deferred indefinitely unless specific need arises.
+
+---
+
+## Phase 1 Recap (for reference)
+
+Phase 1 delivers the Reasoning Journal with:
+
+```ts
+// taskExecutionResult β€” Phase 1 fields
+interface TaskExecutionResult {
+  taskId: string;
+  nodeId: string;
+  status: ExecutionTaskStatus;
+  taskType: "code_generation" | "refactor" | "bugfix" | "test_generation" | "documentation" | "unknown";
+  reasoning: string;          // free-text, min 10 chars, max 2000 chars
+  changes: FileChange[];      // { file, action, summary }[]
+}
+```
+
+- `schemaVersion: "1.0"` added to RunRecord
+- `renamed` added to `fileChange.action` enum
+- `summary` on `FileChange` capped at 200 chars

+# Testing `codeflow-store` in Isolation
+
+This guide tests every sub-module of `codeflow-store` from scratch, using only the package itself β€” no monorepo, no Next.js app, no other CodeFlow packages.
+
+---
+
+## Prerequisites
+
+You need `node` and `npm` installed. No other dependencies.
+
+---
+
+## Setup
+
+```bash
+# 1. Navigate to the package
+cd /Users/abhinavnehra/git/CodeFlow/packages/codeflow-store
+
+# 2. Install dependencies (if not already installed)
+npm install
+
+# 3. Build (if dist/ is not present or stale)
+npm run build
+
+# 4. Set an isolated store root so tests don't pollute your real ~/.codeflow-store
+export CODEFLOW_STORE_ROOT=/tmp/cf-store-test
+rm -rf /tmp/cf-store-test
+```
+
+All commands below assume `CODEFLOW_STORE_ROOT=/tmp/cf-store-test` is set. Every command writes to `/tmp/cf-store-test/` and nowhere else.
+
+---
+
+## Part 0 β€” Generate a Blueprint (using `codeflow-core`)
+
+Most tests below use the pre-built `test-fixtures/blueprint.json` files. But you can also generate a fresh blueprint from scratch using `codeflow-core`'s `buildBlueprintGraph`.
+
+> **Note:** `codeflow-core` must be built first. From the monorepo root:
+> ```bash
+> npm run build --workspace=@abhinav2203/codeflow-core
+> ```
+
+`codeflow-core` exposes `buildBlueprintGraph` from `src/analyzer/build.ts`. It accepts either a **PRD text** (markdown describing what to build) or a **repo path** (reverse-mode: analyzes existing TypeScript code to produce a blueprint).
+
+### 0.1 β€” Generate from PRD text
+
+```bash
+node -e "
+import { buildBlueprintGraph } from '/Users/abhinavnehra/git/CodeFlow/codeflow-core/src/analyzer/build.js';
+
+const graph = await buildBlueprintGraph({
+  projectName: 'my-app',
+  mode: 'essential',
+  prdText: \`
+# Screens
+- Login screen
+- Dashboard
+
+# APIs
+- GET /users
+- POST /orders
+
+# Modules
+- auth.ts: handles authentication
+  -> calls: validateToken
+  -> reads-state: session
+
+# Workflows
+Login screen -> Dashboard
+  \`
+});
+
+console.log(JSON.stringify(graph, null, 2));
+" > /tmp/my-blueprint.json
+```
+
+Expected output β€” a full `BlueprintGraph` with `nodes[]`, `edges[]`, and `workflows[]`:
+```json
+{
+  "projectName": "my-app",
+  "mode": "essential",
+  "phase": "spec",
+  "generatedAt": "<ISO timestamp>",
+  "nodes": [
+    { "id": "n1", "kind": "ui-screen", "name": "Login screen", ... },
+    { "id": "n2", "kind": "ui-screen", "name": "Dashboard", ... },
+    { "id": "n3", "kind": "module", "name": "auth", "path": "auth.ts", ... }
+  ],
+  "edges": [
+    { "from": "n1", "to": "n3", "kind": "calls", ... }
+  ],
+  "workflows": [
+    { "name": "login -> dashboard", "steps": ["Login screen", "Dashboard"] }
+  ],
+  "warnings": []
+}
+```
+
+### 0.2 β€” Generate from an existing TypeScript repo (reverse mode)
+
+Point `repoPath` at any TypeScript project:
+
+```bash
+mkdir -p /tmp/test-repo/src
+cat << 'EOF' > /tmp/test-repo/src/index.ts
+export function authenticate(email: string, password: string) {
+  return { token: 'fake-token', email };
+}
+EOF
+
+node -e "
+import { buildBlueprintGraph } from '/Users/abhinavnehra/git/CodeFlow/codeflow-core/src/analyzer/build.js';
+
+const graph = await buildBlueprintGraph({
+  projectName: 'reverse-test',
+  mode: 'essential',
+  repoPath: '/tmp/test-repo/src'
+});
+
+console.log(JSON.stringify(graph, null, 2));
+"
+```
+
+This extracts functions, classes, imports, and call relationships from the AST to build a blueprint automatically.
+
+### 0.3 β€” Validate a blueprint schema
+
+Once you have a `blueprint.json`, validate it matches the expected schema:
+
+```bash
+node -e "
+import { blueprintGraphSchema } from '/Users/abhinavnehra/git/CodeFlow/codeflow-core/src/schema/index.js';
+import { readFileSync } from 'node:fs';
+
+const raw = JSON.parse(readFileSync('/tmp/my-blueprint.json', 'utf8'));
+const result = blueprintGraphSchema.safeParse(raw);
+
+if (result.success) {
+  console.log('Blueprint is valid!');
+} else {
+  console.error('Blueprint is invalid:', result.error);
+  process.exit(1);
+}
+"
+```
+
+### What the pipeline looks like
+
+```

+               β–Ό
+         BlueprintGraph
+         { nodes[], edges[], workflows[] }
+```
+
+The two modes can be combined β€” pass both `prdText` and `repoPath` to merge a PRD's planned structure with the reality of existing code.
+
+---
+
+## Part 1 β€” Unit Tests
+
+Run the existing test suite:
+
+```bash
+npm test
+```
+
+Expected output:
+```
+ βœ“ src/session.test.ts > codeflow-store > session > creates a valid session ID
+ βœ“ src/session.test.ts > codeflow-store > risk > assesses export risk for a minimal blueprint
+ βœ“ src/session.test.ts > codeflow-store > risk > flags yolo mode in risk assessment
+```
+
+All 3 tests should pass.
+
+---
+
+## Part 2 β€” Type Checking
+
+```bash
+npm run check
+```
+
+Expected: no output (TypeScript compiles cleanly with no errors).
+
+---
+
+## Part 3 β€” Risk Assessment
+
+Risk is the only sub-module that requires **no file I/O** β€” it purely computes a score from a blueprint + run plan. This is the easiest thing to test end-to-end.
+
+### 3.1 β€” Low risk (minimal blueprint, no existing output)
+
+```bash
+node dist/bin/cli.js risk assess test-fixtures/minimal-blueprint.json
+```
+
+Expected output:
+```json
+{
+  "fingerprint": "<a 64-char sha256 hex string>",
+  "outputDir": "<cwd>/artifacts/test-project",
+  "riskReport": {
+    "score": 0,
+    "level": "low",
+    "requiresApproval": false,
+    "factors": []
+  },
+  "hasExistingOutput": false
+}
+```
+
+### 3.2 β€” Medium risk (has existing output directory)
+
+```bash
+# Create the output directory to trigger the "overwrite-existing-output" factor
+mkdir -p /tmp/cf-store-test/artifacts/test-project
+echo "some existing file" > /tmp/cf-store-test/artifacts/test-project/existing.ts
+
+# Re-run risk assessment β€” should now flag existing output
+node dist/bin/cli.js risk assess test-fixtures/minimal-blueprint.json
+```
+
+Expected output β€” `score` should be `4`, `level` should be `"medium"`, and `factors` should contain:
+```json
+{
+  "code": "overwrite-existing-output",
+  "message": "Output directory .../artifacts/test-project already contains files.",
+  "score": 4
+}
+```
+
+### 3.3 β€” High risk (yolo mode)
+
+Yolo mode skips approval gates. Create a blueprint with `mode: "yolo"`:
+
+```bash
+cat << 'EOF' > /tmp/yolo-blueprint.json
+{
+  "projectName": "yolo-project",
+  "mode": "yolo",
+  "generatedAt": "2026-01-01T00:00:00.000Z",
+  "nodes": [],
+  "edges": [],
+  "workflows": [],
+  "warnings": []
+}
+EOF
+
+node dist/bin/cli.js risk assess /tmp/yolo-blueprint.json
+```
+
+Expected: `score` includes at least `2` from the `yolo-mode` factor.
+
+### 3.4 β€” Risk on a real blueprint from codeflow-core
+
+Generate a real blueprint using Part 0, then assess its risk:
+
+```bash
+# Generate a blueprint (from Part 0)
+node -e "
+import { buildBlueprintGraph } from '/Users/abhinavnehra/git/CodeFlow/codeflow-core/src/analyzer/build.js';
+const graph = await buildBlueprintGraph({
+  projectName: 'real-app',
+  mode: 'essential',
+  prdText: \`
+# Screens
+- Login
+- Dashboard
+
+# Modules
+- auth.ts: handles login with email and password
+- db.ts: database connection module
+- dashboard.ts: renders dashboard data
+
+# APIs
+- GET /api/users
+- POST /api/auth/login
+
+# Workflows
+Login -> Dashboard
+  \`
+});
+console.log(JSON.stringify(graph));
+" > /tmp/real-blueprint.json
+
+# Assess risk on the real blueprint
+node dist/bin/cli.js risk assess /tmp/real-blueprint.json
+```
+
+Expected: risk factors should include `repo-backed-context` (nodes have source refs), `large-task-set` (if tasks β‰₯ 20), etc. A small blueprint should score low.
+
+---
+
+## Part 4 β€” Session Management
+
+The session store persists a `PersistedSession` (blueprint graph + run plan) to disk.
+
+### 4.1 β€” Initialize a new session
+
+```bash
+node dist/bin/cli.js session init "test-project"
+```
+
+Expected output:
+```json
+{
+  "sessionId": "<a uuid>",
+  "projectName": "test-project",
+  "updatedAt": "<ISO timestamp>",
+  "repoPath": null,
+  "graph": {
+    "projectName": "test-project",
+    "mode": "essential",
+    "nodes": [],
+    "edges": [],
+    "workflows": [],
+    "warnings": []
+  },
+  "runPlan": {
+    "tasks": [],
+    "batches": []
+  },
+  "lastRiskReport": null,
+  "lastExportResult": null,
+  "lastExecutionReport": null,
+  "approvalIds": []
+}
+```
+
+Verify it was written to disk:
+```bash
+cat /tmp/cf-store-test/sessions/test-project/latest.json
+# β†’ should match the output above (same sessionId, etc.)
+```
+
+### 4.2 β€” Load the latest session
+
+```bash
+node dist/bin/cli.js session last "test-project"
+```
+
+Expected: returns the same session as step 4.1 (sessionId, graph, etc.).
+
+### 4.3 β€” Session survives a process restart (load from disk)
+
+```bash
+# Run a new node process β€” no in-memory state carried over
+node dist/bin/cli.js session last "test-project"
+```
+
+Expected: same session data, proving it was persisted to disk and re-loaded correctly.
+
+### 4.4 β€” Session with a real repo path
+
+```bash
+mkdir -p /tmp/test-repo
+node dist/bin/cli.js session init "repo-project"
+# Note: the CLI's "session init" currently creates a blank session.
+# To test with a repo path, manually edit the session JSON:
+echo '{"sessionId":"test","projectName":"repo-project","repoPath":"/tmp/test-repo","graph":{...}}' > /tmp/cf-store-test/sessions/repo-project/latest.json
+```
+
+---
+
+## Part 5 β€” Approval Workflow
+
+The approval store manages export requests that require human sign-off.
+
+### 5.1 β€” Create an approval record
+
+You need to construct the full approval record manually since there's no CLI subcommand for creation (it's done by the export flow):
+
+```bash
+node -e "
+const { createApprovalRecord } = await import('./dist/approval/index.js');
+
+const record = await createApprovalRecord({
+  projectName: 'test-project',
+  fingerprint: 'abc123fingerprint',
+  outputDir: '/tmp/test-output',
+  runPlan: { generatedAt: new Date().toISOString(), tasks: [], batches: [], warnings: [] },
+  riskReport: { score: 6, level: 'high', requiresApproval: true, factors: [] }
+});
+
+console.log(JSON.stringify(record, null, 2));
+"
+```
+
+Expected output:
+```json
+{
+  "id": "<a uuid>",
+  "action": "export",
+  "projectName": "test-project",
+  "status": "pending",
+  "fingerprint": "abc123fingerprint",
+  "requestedAt": "<ISO timestamp>",
+  "outputDir": "/tmp/test-output",
+  "runPlan": {...},
+  "riskReport": {...}
+}
+```
+
+Verify it was written to disk:
+```bash
+cat /tmp/cf-store-test/approvals/<approval-id>.json
+```
+
+### 5.2 β€” Get an approval record
+
+```bash
+# Replace <approval-id> with the id from step 5.1
+node dist/bin/cli.js approval get <approval-id>
+```
+
+Expected: returns the same approval record.
+
+### 5.3 β€” Approve the record
+
+```bash
+node dist/bin/cli.js approval approve <approval-id>
+```
+
+Expected output β€” `status` changes from `"pending"` to `"approved"`, and `approvedAt` is set:
+```json
+{
+  "id": "<approval-id>",
+  "status": "approved",
+  "approvedAt": "<ISO timestamp>",
+  ...
+}
+```
+
+Verify the file was updated on disk:
+```bash
+cat /tmp/cf-store-test/approvals/<approval-id>.json
+# β†’ status should be "approved"
+```
+
+### 5.4 β€” Approval for non-existent record
+
+```bash
+node dist/bin/cli.js approval get does-not-exist-id
+```
+
+Expected: exits with code 1 and error message `Approval does-not-exist-id was not found.`
+
+---
+
+## Part 6 β€” Checkpoints
+
+Checkpoints copy an entire project directory to a timestamped location. They let you roll back to a known-good state.
+
+### 6.1 β€” Create a checkpoint
+
+```bash
+# First, create a "project" directory with some files
+mkdir -p /tmp/my-project/src
+echo "console.log('hello')" > /tmp/my-project/src/index.ts
+echo "const x = 1" > /tmp/my-project/src/utils.ts
+
+# Create a checkpoint
+CHECKPOINT_ID="checkpoint-$(date +%s)"
+node dist/bin/cli.js checkpoint create "$CHECKPOINT_ID" /tmp/my-project
+```
+
+Expected output:
+```json
+{
+  "checkpointDir": "/tmp/cf-store-test/checkpoints/<checkpoint-id>"
+}
+```
+
+Verify the directory was copied:
+```bash
+ls /tmp/cf-store-test/checkpoints/<checkpoint-id>/src/
+# β†’ index.ts  utils.ts
+cat /tmp/cf-store-test/checkpoints/<checkpoint-id>/src/index.ts
+# β†’ console.log('hello')
+```
+
+### 6.2 β€” Modify the project, then restore the checkpoint
+
+```bash
+# Modify the project
+echo "console.log('modified')" > /tmp/my-project/src/index.ts
+
+# Verify it's changed
+cat /tmp/my-project/src/index.ts
+# β†’ console.log('modified')
+
+# Restore the checkpoint (copy it back)
+cp -r /tmp/cf-store-test/checkpoints/<checkpoint-id>/* /tmp/my-project/
+
+# Verify the original is back
+cat /tmp/my-project/src/index.ts
+# β†’ console.log('hello')
+```
+
+---
+
+## Part 7 β€” Run Records
+
+Run records store the result of every execution of a blueprint.
+
+### 7.1 β€” Save a run record
+
+```bash
+node -e "
+const { saveRunRecord, createRunId } = await import('./dist/run/index.js');
+
+const runId = createRunId();
+const record = {
+  id: runId,
+  projectName: 'test-project',
+  sessionId: 'test-session-123',
+  status: 'success',
+  startedAt: new Date().toISOString(),
+  completedAt: new Date().toISOString(),
+  tasks: [
+    { id: 'task-1', nodeId: 'n1', status: 'success', durationMs: 120 }
+  ],
+  batches: [
+    { index: 0, taskIds: ['task-1'], status: 'completed' }
+  ],
+  artifacts: [],
+  errors: []
+};
+
+await saveRunRecord(record);
+console.log('Saved run:', runId);
+"
+```
+
+Verify it was written:
+```bash
+cat /tmp/cf-store-test/runs/<run-id>.json
+# β†’ should contain the run record
+```
+
+### 7.2 β€” List all run records
+
+```bash
+node dist/bin/cli.js run list
+```
+
+Expected: returns a JSON array of filenames like `["<run-id-1>.json", "<run-id-2>.json"]`.
+
+---
+
+## Part 8 β€” Branch Management
+
+Branches let you maintain multiple named variants of a blueprint simultaneously.
+
+### 8.1 β€” Save a named branch
+
+```bash
+node -e "
+const { saveBranch } = await import('./dist/branch/index.js');
+
+const branch = {
+  id: 'feature-auth',
+  projectName: 'test-project',
+  name: 'feature-auth',
+  description: 'Authentication module variant',
+  createdAt: new Date().toISOString(),
+  updatedAt: new Date().toISOString(),
+  graph: {
+    projectName: 'test-project',
+    mode: 'essential',
+    nodes: [
+      { id: 'n1', kind: 'screen', summary: 'Login screen' }
+    ],
+    edges: [],
+    workflows: [],
+    warnings: []
+  },
+  metadata: {}
+};
+
+await saveBranch(branch);
+console.log('Saved branch');
+"
+```
+
+Verify it was written:
+```bash
+cat /tmp/cf-store-test/branches/test-project/feature-auth.json
+```
+
+### 8.2 β€” List all branches
+
+```bash
+node dist/bin/cli.js branch list test-project
+```
+
+Expected: returns an array with the `feature-auth` branch.
+
+### 8.3 β€” Load a specific branch
+
+```bash
+node -e "
+const { loadBranch } = await import('./dist/branch/index.js');
+const branch = await loadBranch('test-project', 'feature-auth');
+console.log(JSON.stringify(branch, null, 2));
+"
+```
+
+Expected: returns the branch with `id: "feature-auth"`.
+
+### 8.4 β€” Delete a branch
+
+```bash
+node -e "
+const { deleteBranch } = await import('./dist/branch/index.js');
+await deleteBranch('test-project', 'feature-auth');
+console.log('Deleted');
+"
+
+# Verify it's gone
+node dist/bin/cli.js branch list test-project
+# β†’ should return []
+```
+
+---
+
+## Part 9 β€” Observability
+
+Observability stores merged trace spans and logs from execution runs.
+
+### 9.1 β€” Merge spans and logs into a snapshot
+
+```bash
+# Create sample spans
+cat << 'EOF' > /tmp/spans.json
+[
+  {
+    "name": "auth.validate",
+    "spanId": "s1",
+    "traceId": "t1",
+    "startTime": "2026-01-01T10:00:00.000Z",
+    "endTime": "2026-01-01T10:00:01.000Z",
+    "status": "ok",
+    "attributes": {}
+  }
+]
+EOF
+
+# Create sample logs
+cat << 'EOF' > /tmp/logs.json
+[
+  { "level": "info", "message": "Server started", "timestamp": "2026-01-01T10:00:00.000Z" }
+]
+EOF
+
+# Merge into observability snapshot
+node dist/bin/cli.js observability merge test-project /tmp/spans.json /tmp/logs.json
+```
+
+Expected output:
+```json
+{
+  "projectName": "test-project",
+  "updatedAt": "<ISO timestamp>",
+  "spans": [...],
+  "logs": [...]
+}
+```
+
+### 9.2 β€” Load the observability snapshot
+
+```bash
+node dist/bin/cli.js observability get test-project
+```
+
+Expected: returns the same snapshot from step 9.1.
+
+### 9.3 β€” Merging appends, not replaces
+
+```bash
+# Add more spans
+cat << 'EOF' > /tmp/spans2.json
+[
+  {
+    "name": "auth.login",
+    "spanId": "s2",
+    "traceId": "t1",
+    "startTime": "2026-01-01T10:00:02.000Z",
+    "endTime": "2026-01-01T10:00:03.000Z",
+    "status": "ok",
+    "attributes": {}
+  }
+]
+EOF
+
+cat << 'EOF' > /tmp/logs2.json
+[]
+EOF
+
+node dist/bin/cli.js observability merge test-project /tmp/spans2.json /tmp/logs2.json
+
+# Reload and verify both spans are present
+node dist/bin/cli.js observability get test-project
+# β†’ spans should contain BOTH s1 and s2
+```
+
+### 9.4 β€” Observability caps at 500 items
+
+```bash
+# Create 600 spans
+node -e "
+const { mergeObservabilitySnapshot } = await import('./dist/observability/index.js');
+const spans = Array.from({ length: 600 }, (_, i) => ({
+  name: 'span-' + i,
+  spanId: 's' + i,
+  traceId: 't1',
+  startTime: new Date().toISOString(),
+  endTime: new Date().toISOString(),
+  status: 'ok',
+  attributes: {}
+}));
+await mergeObservabilitySnapshot({ projectName: 'test-project', spans, logs: [] });
+console.log('done');
+"
+
+node dist/bin/cli.js observability get test-project
+# β†’ spans.length should be 500 (not 600)
+```
+
+---
+
+## Part 10 β€” Store Root Environment Variable
+
+Verify that `CODEFLOW_STORE_ROOT` is respected and that multiple projects are fully isolated:
+
+```bash
+# Use a fresh store root
+export CODEFLOW_STORE_ROOT=/tmp/cf-store-isolated
+rm -rf /tmp/cf-store-isolated
+
+# Create a session for project A
+node dist/bin/cli.js session init "project-a"
+# β†’ stored in /tmp/cf-store-isolated/sessions/project-a/latest.json
+
+# Create a session for project B
+node dist/bin/cli.js session init "project-b"
+# β†’ stored in /tmp/cf-store-isolated/sessions/project-b/latest.json
+
+# Verify they are separate
+ls /tmp/cf-store-isolated/sessions/
+# β†’ project-a  project-b
+
+# Each session should only return its own project
+node dist/bin/cli.js session last "project-a"
+node dist/bin/cli.js session last "project-b"
+# β†’ each returns the correct project, no mixing
+```
+
+---
+
+## Part 11 β€” Full End-to-End Scenario
+
+Simulate a real-world workflow using all sub-modules:
+
+```bash
+export CODEFLOW_STORE_ROOT=/tmp/cf-e2e
+rm -rf /tmp/cf-e2e
+
+PROJECT="my-app"
+mkdir -p /tmp/$PROJECT/src
+
+# Step 1 β€” Initialize session
+SESSION=$(node dist/bin/cli.js session init "$PROJECT")
+echo "Session created"
+
+# Step 2 β€” Do some work (create a checkpoint before)
+CHECKPOINT_ID="pre-refactor-$(date +%s)"
+cp -r /tmp/$PROJECT /tmp/$PROJECT-backup  # simulate the "project dir" for checkpoint
+node dist/bin/cli.js checkpoint create "$CHECKPOINT_ID" /tmp/$PROJECT-backup
+
+# Step 3 β€” Assess risk
+node dist/bin/cli.js risk assess test-fixtures/sample-blueprint.json /tmp/$PROJECT/artifacts
+
+# Step 4 β€” Verify no approvals needed for low risk
+# (sample-blueprint has no existing output, so risk should be low)
+
+# Step 5 β€” Save a run record
+node -e "
+const { saveRunRecord, createRunId } = await import('./dist/run/index.js');
+await saveRunRecord({
+  id: createRunId(),
+  projectName: '$PROJECT',
+  sessionId: 'sess-1',
+  status: 'success',
+  startedAt: new Date().toISOString(),
+  completedAt: new Date().toISOString(),
+  tasks: [{ id: 't1', nodeId: 'n1', status: 'success', durationMs: 50 }],
+  batches: [{ index: 0, taskIds: ['t1'], status: 'completed' }],
+  artifacts: [],
+  errors: []
+});
+"
+
+# Step 6 β€” Create a branch
+node -e "
+const { saveBranch } = await import('./dist/branch/index.js');
+await saveBranch({
+  id: 'v2',
+  projectName: '$PROJECT',
+  name: 'v2',
+  description: 'Architecture variant 2',
+  createdAt: new Date().toISOString(),
+  updatedAt: new Date().toISOString(),
+  graph: { projectName: '$PROJECT', mode: 'essential', nodes: [], edges: [], workflows: [], warnings: [] },
+  metadata: {}
+});
+"
+
+# Step 7 β€” List branches
+node dist/bin/cli.js branch list "$PROJECT"
+# β†’ should contain v2
+
+# Step 8 β€” Verify all run records
+node dist/bin/cli.js run list
+# β†’ should have at least one run record
+
+echo "End-to-end scenario complete!"
+```
+
+---
+
+## File System State After All Tests
+
+After running all tests with `CODEFLOW_STORE_ROOT=/tmp/cf-store-test`, the directory should look like:
+
+```
+/tmp/cf-store-test/
+β”œβ”€β”€ sessions/
+β”‚   β”œβ”€β”€ test-project/latest.json
+β”‚   └── repo-project/latest.json
+β”œβ”€β”€ approvals/
+β”‚   └── <approval-id>.json
+β”œβ”€β”€ checkpoints/
+β”‚   └── <checkpoint-id>/
+β”‚       └── src/
+β”‚           β”œβ”€β”€ index.ts
+β”‚           └── utils.ts
+β”œβ”€β”€ runs/
+β”‚   └── <run-id>.json
+β”œβ”€β”€ observability/
+β”‚   └── test-project.json
+└── branches/
+    └── test-project/
+        └── feature-auth.json
+```
+
+---
+
+## Troubleshooting
+
+### "No session found for project: test-project"
+
+You forgot to set `CODEFLOW_STORE_ROOT`. Sessions are being written to `~/.codeflow-store/` instead of your test dir. Run:
+```bash
+export CODEFLOW_STORE_ROOT=/tmp/cf-store-test
+```
+
+### "dist/bin/cli.js: not found"
+
+Run:
+```bash
+npm run build
+```
+
+### TypeScript errors on `npm run check`
+
+Run build from the monorepo root β€” `codeflow-store` depends on `@abhinav2203/codeflow-core` which must be built first:
+```bash
+cd /Users/abhinavnehra/git/CodeFlow
+npm run build --workspace=@abhinav2203/codeflow-core
+npm run build --workspace=@abhinav2203/codeflow-store

+# Phase 2 β€” What We're Adding and Why
+
+## What Phase 2 Is
+
+Phase 1 (done) gave every task execution a `reasoning` field (free-text) + `changes[]` (what files changed) + `taskType`. Phase 2 extends the store with four focused features.
+
+---
+
+## The Four Things We're Adding
+
+### P2-1 β€” Link trace spans to tasks
+**What:** Add `taskId` to `traceSpanSchema` (one line in codeflow-core schema).
+**Why:** Right now you can see a span ran but not which task triggered it. With `taskId`, you can filter spans per-task and build trace waterfalls: span β†’ task β†’ node β†’ run record.
+**New files:** None.
+
+---
+
+### P2-2 β€” Configurable ring-buffer for spans and logs
+**What:** Replace the hardcoded `.slice(-500)` with a proper `RingBuffer<T>` class. Separate caps for spans (default 500) and logs (default 2000). Per-project config override.
+**Why:** The hardcoded cap silently drops data β€” a busy agent with 20 tasks Γ— 50 spans = 1,000 spans, but only 500 survive. Spans (~100–500 bytes) and logs (~1–10 KB) have completely different sizes; same cap treats them identically.
+**New files:** `ring-buffer.ts`, `config.ts`, two test files.
+**Config file:** `{storeRoot}/observability-config/{projectSlug}.json`
+
+---
+
+### P2-4 β€” Crash recovery checkpoints
+**What:** Write reasoning to disk *before* task execution. If the process crashes, recover it from the checkpoint file.
+**Why:** Currently reasoning lives in memory until `saveRunRecord()` is called at end of run. Crash = reasoning gone forever.
+**New files:** `src/checkpoint/reasoning.ts` (save/load/recover/clear API)
+**Checkpoint path:** `{storeRoot}/checkpoints/reasoning/{runId}/{projectSlug}/{taskId}.json`
+**Agent-side:** Agent calls `saveTaskReasoningCheckpoint` before task, `clearTaskReasoningCheckpoint` after `saveRunRecord`.
+
+---
+
+### P2-5 β€” Reasoning journal for CodeRAG
+**What:** Pull API β€” `loadReasoningForProject(projectName)` and `loadReasoningForRun(runId, projectName)`. CodeRAG calls these on reindex.
+**Why:** The reasoning stored in run records needs to be indexable by CodeRAG's vector search. Pull model means no coupling β€” CodeRAG reads when it needs to reindex, codeflow-store doesn't need to know about CodeRAG.
+**New files:** `src/reasoning/index.ts`, test file.
+**coderag side:** Its own adapter calls `loadReasoningForProject()` on reindex. No events, no webhooks.
+
+---
+
+## What We're NOT Adding (Deferred)
+
+- **P2-3 Token tracking** β€” not needed yet; reasoning free-text is enough for now
+- **P2-6 LLM output storage** β€” compliance/archive feature, premature until actually required
+
+---
+
+## How It Fits Together
+
+```
+Agent runs task
+  β†’ P2-4: saveTaskReasoningCheckpoint (write-ahead, before work)
+  β†’ does task work
+  β†’ P2-1: emits span with taskId (links span to task)
+  β†’ P2-2: observability stores span/log (ring-buffer caps applied)
+  β†’ P2-4: clearTaskReasoningCheckpoint (after saveRunRecord)
+  β†’ P2-5: CodeRAG reindexes β†’ calls loadReasoningForProject()
+```
