 If the API is not running, the workbench marks the control-plane as offline, shows stale fixture fallback where appropriate, and keeps rendering deterministic local data. This app is for private/local validation and canary review only; it does not initiate value-bearing wallet flows.
 
+## Beginner Demo Path
+
+The full launch-demo script lives in:
+
+```text
+docs/LAUNCH_DEMO_RUNBOOK.md
+```
+
+From the repo root, the normal browser-demo setup is:
+
+```powershell
+npm run flowchain:init
+npm run flowchain:start
+npm run flowchain:demo
+npm run flowchain:export
+```
+
+Then start the local API and workbench in separate PowerShell windows:
+
+```powershell
+npm run control-plane:serve
+```
+
+```powershell
+npm run workbench:dev
+```
+
+Open the Vite URL, usually:
+
+```text
+http://127.0.0.1:5173/
+```
+
+Click path for a short demo:
+
+1. **Workbench** (`/`) for local API status, setup path, object switcher, provenance, and raw private/local object views.
+2. **Overview** (`/overview`) for local fixture metrics, recent FlowPulse observations, verifier attention, hardware risk, and devnet block window.
+3. **Flow Memory** (`/flowmemory`) for MemorySignal, MemoryReceipt, RootfieldBundle, AgentMemoryView, and RootflowTransition state.
+4. **Base canary** (`/canary`) for the isolated guarded canary review. This is not a production-readiness claim.
+5. **Raw JSON** (`/raw`) only when a reviewer asks for the payload behind the UI.
+
+Workbench panel meanings:
+
+| Panel | Meaning |
+| --- | --- |
+| Node and API status | Local chain/API health, block height, state root, pending transaction count, and API URL. |
+| Local setup path | Beginner command sequence for installing, refreshing launch fixtures, starting, smoking, and opening the workbench. |
+| Control-plane endpoints and local actions | Local API endpoints and optional browser-safe actions when the API advertises them. |
+| Workbench coverage metrics | Counts for data source, node views, chain objects, smoke objects, and challenges. |
+| Object switcher | Clickable local object views such as blocks, transactions, agents, models, receipts, reports, memory cells, challenges, finality, bridge-shaped local test objects, provenance, hardware signals, and raw JSON. |
+
+Canary panel meanings:
+
+| Panel | Meaning |
+| --- | --- |
+| Canary boundary hero | Reminder that the current Base canary is visible on Base but still gated for production. |
+| Reader command / review fixture / hard boundary strip | The reader shape, runtime fixture path, and no broad scan/no production/no real-funds boundary. |
+| Canary metrics | Counts from the committed canary fixture, including rejected logs and duplicates. |
+| Canary FlowPulse stream | Observed canary logs with block, pulse type, transaction hash, and log index. |
+| FlowPulse contracts | Canary contracts that emitted FlowPulse logs in the review fixture. |
+| Launch gates | Remaining boundaries before any production claim. |
+| Canary Rootflow state | Rootflow transitions reconstructed from the canary observations. |
+| Canary JSON | Full loaded canary dashboard payload for reviewer inspection. |
+

+# Base Sepolia Deployment Rehearsal
+
+Status: V0 public testnet rehearsal path.
+
+This is not a production deployment guide, production mainnet guide, token
+launch guide, custody guide, bridge guide, verifier-network guide, or
+production Uniswap v4 hook guide.
+
+## Goal
+
+Use Base Sepolia to rehearse the current V0 contract package end to end:
+
+1. generate a non-secret deployment plan;
+2. run a Foundry dry run with explicit local env values;
+3. optionally broadcast to Base Sepolia after operator approval;
+4. emit one tiny Rootfield/FlowPulse write path;
+5. read the resulting FlowPulse logs with the Base Sepolia reader;
+6. persist indexer state and checkpoint output;
+7. record verification, rollback, and boundary notes.
+
+## Environment
+
+Use an ignored `.env` file or shell variables only. Do not paste real values into
+docs, GitHub issues, PR comments, screenshots, or committed artifacts.
+
+Required for dry-run or broadcast:
+
+```powershell
+$env:BASE_SEPOLIA_RPC_URL="<base-sepolia-rpc-url>"
+$env:BASE_SEPOLIA_DEPLOYER_KEY_HEX="<0x-prefixed-32-byte-testnet-key>"
+```
+
+Optional:
+
+```powershell
+$env:BASE_SEPOLIA_BASESCAN_API_KEY="<basescan-api-key>"
+$env:BASE_SEPOLIA_FLOWPULSE_ADDRESSES="<comma-separated-addresses-after-deploy>"
+$env:BASE_SEPOLIA_FROM_BLOCK="<first-deploy-or-smoke-block>"
+$env:BASE_SEPOLIA_TO_BLOCK="<latest-reviewed-block>"
+$env:BASE_SEPOLIA_FINALIZED_BLOCK="<safe-finalized-block>"
+```
+
+The repo also accepts `BASESCAN_API_KEY` as a fallback explorer key name. The
+scripts redact key presence and never write the key value.
+
+## Plan-Only Command
+
+This command requires no private key and writes the non-secret plan artifact:
+
+```powershell
+npm run deploy:base-sepolia:plan -- --json
+```
+
+Default output:
+
+```text
+fixtures/deployments/base-sepolia-rehearsal-plan.json
+```
+
+The plan records:
+
+- required env names;
+- contract names deployed by `DeployLaunchCandidate`;
+- the redacted Foundry command;
+- write smoke command templates;
+- readback command templates;
+- explorer verification command template;
+- rollback notes and blocked claims.
+
+## Dry Run
+
+Run this before any Base Sepolia broadcast:
+
+```powershell
+npm run deploy:base-sepolia -- --json
+```
+
+Default output when the dry run succeeds:
+
+```text
+fixtures/deployments/base-sepolia-rehearsal.latest.json
+```
+
+The Foundry script now rejects the wrong chain id and expects Base Sepolia
+`84532`.
+
+## Optional Broadcast
+
+Broadcast only after the operator approves testnet gas spend and confirms the
+deployer key is a testnet key:
+
+```powershell
+npm run deploy:base-sepolia:broadcast -- --json
+```
+
+After broadcast, copy only non-secret facts into a dated deployment doc:
+
+- deployer address;
+- contract names and addresses;
+- deploy transaction hashes;
+- deployment blocks;
+- source verification status;
+- smoke transaction hashes;
+- reader checkpoint paths.
+
+## Write Smoke
+
+Use small deterministic testnet values. These commands are templates; replace
+addresses and hashes from the deployment artifact or Foundry broadcast output.
+
+```powershell
+cast send <RootfieldRegistry> "registerRootfield(bytes32,bytes32,bytes32,string)" <rootfieldId> <schemaHash> <metadataHash> "ipfs://flowmemory-base-sepolia-rehearsal" --rpc-url $env:BASE_SEPOLIA_RPC_URL --private-key $env:BASE_SEPOLIA_DEPLOYER_KEY_HEX
+```
+
+```powershell
+cast send <RootfieldRegistry> "submitRoot(bytes32,bytes32,bytes32,bytes32,string)" <rootfieldId> <root> <artifactCommitment> <parentPulseId> "ipfs://flowmemory-base-sepolia-rehearsal-root" --rpc-url $env:BASE_SEPOLIA_RPC_URL --private-key $env:BASE_SEPOLIA_DEPLOYER_KEY_HEX
+```
+
+Optional hook-adapter smoke:
+
+```powershell
+cast send <FlowMemoryHookAdapter> "afterSwap(address,bytes32,bytes32,bytes32,bytes)" <sender> <poolId> <rootfieldId> <commitment> 0x1234 --rpc-url $env:BASE_SEPOLIA_RPC_URL --private-key $env:BASE_SEPOLIA_DEPLOYER_KEY_HEX
+```
+
+These writes are for public testnet rehearsal only. They do not prove
+production hook readiness.
+
+## Readback
+
+Read contract state:
+
+```powershell
+cast call <RootfieldRegistry> "getRootfield(bytes32)" <rootfieldId> --rpc-url $env:BASE_SEPOLIA_RPC_URL
+```
+
+Read FlowPulse logs:
+
+```powershell
+npm run index:base-sepolia -- --rpc-url $env:BASE_SEPOLIA_RPC_URL --address <RootfieldRegistry> --address <FlowMemoryHookAdapter> --from-block <deployBlock> --to-block <latestBlock> --finalized-block <safeFinalizedBlock>
+```
+
+Resume from the durable checkpoint:
+
+```powershell
+npm run index:base-sepolia -- --rpc-url $env:BASE_SEPOLIA_RPC_URL --address <RootfieldRegistry> --address <FlowMemoryHookAdapter> --resume-from-checkpoint --to-block <latestBlock>
+```
+
+The reader:
+
+- requires an explicit RPC URL;
+- rejects non-Base-Sepolia chain ids;
+- rejects broad scans above the configured span;
+- stores state and checkpoint JSON atomically;
+- records `lastIndexedBlock`, `highestObservedBlock`, `nextFromBlock`, and
+  `emptyRange`;
+- does not write RPC URLs, private keys, or explorer API keys.
+
+## Source Verification
+
+Use the explorer key only from local env:
+
+```powershell
+forge verify-contract --chain-id 84532 <address> <ContractName> --etherscan-api-key $env:BASE_SEPOLIA_BASESCAN_API_KEY
+```
+
+Record verification result per contract in the dated deployment doc. A verified
+Base Sepolia source is still a testnet fact, not production approval.
+
+## Rollback And Recovery
+
+- If the dry run fails, fix locally and rerun the plan plus dry run.
+- If broadcast fails before all contracts deploy, discard the partial address
+  set unless a reviewer explicitly approves documenting it as failed evidence.
+- If write smoke fails, record the transaction hash and revert reason, then use
+  readback commands to distinguish contract failure from RPC/nonce failure.
+- V0 has no proxy rollback. Stop using an address set by marking it superseded
+  in `docs/DEPLOYMENTS/`.
+- Never reuse a deployer key that was exposed on screen or copied into docs.
+
+## Acceptance Checklist
+
+- `npm run deploy:base-sepolia:plan -- --json` writes a non-secret plan.
+- `npm run deploy:base-sepolia -- --json` dry-runs on chain id `84532`.
+- Optional broadcast is approved and produces dated deployment facts.
+- At least one Rootfield write emits FlowPulse on Base Sepolia.
+- `npm run index:base-sepolia` persists state and checkpoint output.
+- The checkpoint includes resume data and no secret material.
+- Source verification is recorded or explicitly marked pending.
+- `docs/CURRENT_STATE.md` is updated after any real broadcast.
+- No production/mainnet/user-funds claim is made.

+## Workbench And Local Service Recovery
+
+The launch demo uses the dashboard as a local workbench. It can run with either
+the local control-plane API or deterministic fixture fallback.
+
+### Workbench Loads With Fixture Fallback
+
+This is not automatically a failure. It means the browser did not detect the
+local control-plane API at `http://127.0.0.1:8787`.
+
+To switch to local API mode, run in a separate PowerShell window:
+
+```powershell
+cd E:\FlowMemory\flowmemory-main
+npm run control-plane:serve
+```
+
+Refresh the workbench. The banner should change from **Fixture fallback
+active.** to **Local API detected.**
+
+### Control Plane Does Not Start
+
+Run the smallest local recovery path:
+
+```powershell
+cd E:\FlowMemory\flowmemory-main
+npm install
+npm run launch:v0
+npm test --prefix services/control-plane
+npm run control-plane:serve
+```
+
+If port `8787` is already in use, inspect it:
+
+```powershell
+Get-NetTCPConnection -LocalPort 8787 -ErrorAction SilentlyContinue
+```
+
+Close the old PowerShell window that owns the service, or stop the process if
+you intentionally started it and no longer need it.
+
+### Workbench Dev Server Does Not Open
+
+Install dashboard dependencies and rerun the wrapper:
+
+```powershell
+npm install --prefix apps/dashboard
+npm run workbench:dev
+```
+
+Use the URL printed by Vite. It is usually `http://127.0.0.1:5173/`, but Vite
+may choose another port if `5173` is busy.
+
+### Browser Shows Stale Or Missing Dashboard Data
+
+Refresh generated fixtures and sync the dashboard public copy:
+
+```powershell
+npm run launch:v0
+npm run flowmemory:canary-dashboard
+npm run sync:fixtures --prefix apps/dashboard
+npm run workbench:dev
+```
+
+Do not refresh live canary data during a demo unless the operator explicitly
+approves the RPC endpoint, canary addresses, and small block range.
+
+### Local State Looks Corrupt Or Confusing
+
+Reset ignored local state only:
+
+```powershell
+npm run flowchain:stop -- -ResetLocalState
+npm run flowchain:init
+npm run flowchain:start
+npm run flowchain:demo
+```
+
+This does not edit committed fixtures.

+# FlowMemory Launch Demo Runbook
+
+Status: beginner-safe launch demo script for the current V0 local/private and
+guarded canary surfaces.
+
+This runbook is for showing what exists today without overclaiming. It covers:
+
+- the FlowChain private/local no-value workbench;
+- the generated FlowMemory V0 dashboard fixtures;
+- the guarded Base canary review route at `/canary`.
+
+It is not a production runbook, production mainnet announcement, token launch,
+public validator guide, production verifier-network guide, production bridge
+guide, or audited-cryptography statement.
+
+## One-Sentence Demo Frame
+
+Use this at the start:
+
+```text
+This is FlowMemory V0: a local/private no-value FlowChain package and dashboard
+workbench, plus a guarded Base canary review from known canary contracts. It
+shows FlowPulse observations, Rootflow transitions, verifier/report state, and
+operator evidence without claiming production readiness.
+```
+
+## What This Demo Proves
+
+- A beginner can run the current local package from the repo root.
+- The local devnet can initialize deterministic no-value state and produce demo
+  output.
+- The workbench can inspect local fixture state and, when started, the local
+  control-plane API.
+- The canary route can review committed Base canary reader output separately
+  from local/private fixtures.
+- The dashboard makes provenance, status, and boundaries visible instead of
+  hiding them in raw JSON.
+
+## What This Demo Does Not Prove
+
+Do not claim:
+
+- production readiness;
+- mainnet readiness;
+- a production L1;
+- public validator readiness;
+- tokenomics, token launch, or real-funds faucet behavior;
+- production bridge readiness;
+- production Uniswap v4 hook deployment;
+- fully trustless verifier network;
+- audited cryptography;
+- AI, model weights, media, or heavy memory data stored on-chain;
+- FlowRouter hardware manufacturing, certification, or field deployment.
+
+Safe language:
+
+- "local/private no-value validation";
+- "fixture-backed workbench";
+- "guarded Base canary review";
+- "FlowPulse observations";
+- "Rootflow transition model";
+- "commitments, receipts, roots, and verifier reports";
+- "source-verified current canary addresses, not production approval."
+
+## Pre-Demo Setup
+
+Run from the repo root:
+
+```powershell
+cd E:\FlowMemory\flowmemory-main
+git fetch --all --prune
+git status --short --branch
+npm install
+npm install --prefix apps/dashboard
+npm install --prefix crypto
+npm run flowchain:prereq
+```
+
+Expected result:
+
+- `git status --short --branch` shows the intended branch and no unexpected
+  dirty files.
+- `flowchain:prereq` lists Git, Node.js, npm, Rust/Cargo, MSVC build tools,
+  Foundry, and dependency install state.
+- Missing dependencies are fixed before the demo starts.
+
+For a full launch-day gate, run:
+
+```powershell
+npm run flowchain:full-smoke
+```
+
+Expected output files:
+
+```text
+devnet/local/smoke/flowchain-smoke-report.json
+devnet/local/full-smoke/flowchain-full-smoke-report.json
+```
+
+If full smoke cannot run on the demo computer, say exactly which prerequisite or
+step is missing. Do not replace it with "works locally."
+
+## Generate Demo State
+
+Run:
+
+```powershell
+npm run flowchain:init
+npm run flowchain:start
+npm run flowchain:demo
+npm run flowchain:export
+```
+
+What each command does:
+
+| Command | Meaning |
+| --- | --- |
+| `npm run flowchain:init` | Writes deterministic local state under `devnet/local/state.json` and a local-only operator file under `devnet/local/operator.local.json`. |
+| `npm run flowchain:start` | Prepares launch-core fixtures, inspects local state, and writes bounded local stack status. This is not a daemon. |
+| `npm run flowchain:demo` | Runs the deterministic no-value local demo and writes handoff output under `devnet/local/handoff/generated/`. |
+| `npm run flowchain:export` | Writes local export files and a zip bundle under `devnet/local/export/` without including the local operator file. |
+
+## Start The Services For The Browser Demo
+
+Use two PowerShell windows.
+
+Window 1, optional but recommended:
+
+```powershell
+cd E:\FlowMemory\flowmemory-main
+npm run control-plane:serve
+```
+
+Expected local API:
+
+```text
+http://127.0.0.1:8787
+```
+
+Window 2:
+
+```powershell
+cd E:\FlowMemory\flowmemory-main
+npm run workbench:dev
+```
+
+Open the Vite URL printed by the command. It is usually:
+
+```text
+http://127.0.0.1:5173/
+```
+
+If Vite chooses a different port, use the printed URL.
+
+## Browser Click Script
+
+### 1. Workbench
+
+Open:
+
+```text
+http://127.0.0.1:5173/
+```
+
+Or click **Workbench** in the left nav.
+
+Say:
+
+```text
+This is the local operator workbench. It checks the local control-plane API at
+127.0.0.1:8787 and falls back to deterministic fixtures when the API is not
+running. The fallback is intentional for demos; it is not pretending to be a
+hosted production service.
+```
+
+Check the banner under the top bar:
+
+- **Local API detected.** The workbench is reading the local API where
+  available.
+- **Fixture fallback active.** The control-plane service was not detected and
+  the workbench is showing deterministic committed fixtures.
+
+Main Workbench panels:
+
+| Panel | What it means |
+| --- | --- |
+| Node and API status | Current local chain/API health, block height, state root, pending transaction count, and API URL. If it says offline, the dashboard is still usable in fixture fallback mode. |
+| Local setup path | The beginner command sequence the operator should run: install, launch candidate, start, smoke, and open workbench. |
+| Control-plane endpoints and local actions | Endpoints advertised or probed from the local API. Browser action buttons only appear when the API advertises matching safe POST endpoints. |
+| Workbench coverage metrics | Counts for data source, node views, chain objects, smoke objects, and open challenges in the current source. |
+| Object switcher | Clickable object views for Node Status, Peers, Blocks, Transactions, Mempool, Accounts, Balances, Faucet Events, Wallet Metadata, Rootfields, Agents, Models, Work Receipts, Memory Cells, Artifacts, Verifier Modules, Verifier Reports, Challenges, Finality, bridge test objects, Provenance / Source, Hardware Signals, and Raw JSON. |
+| Record grid | The records for the selected object view, including status, facts, and provenance. |
+| Boundary notes | Reminder that this is one local workbench surface, not a second dashboard or production system. |
+
+What to click:
+
+1. Click **Node Status** in the object switcher and point out the state root,
+   chain id, API URL, and provenance.
+2. Click **Blocks** and **Transactions** to show deterministic local chain
+   objects.
+3. Click **Agents**, **Models**, **Work Receipts**, **Verifier Reports**,
+   **Memory Cells**, **Challenges**, and **Finality** to show the local object
+   lifecycle.
+4. Click **Wallet Metadata** and say it is public metadata only. The browser
+   does not ask for private keys.
+5. Click **Bridge Deposits**, **Bridge Credits**, and **Bridge Withdrawals** and
+   say these are private/local bridge-shaped test objects only.
+6. Click **Provenance / Source** to show where the data came from.
+7. Click **Raw JSON** only if a reviewer asks for the payload underneath the UI.
+
+If local action buttons appear, describe them as optional browser-safe local API
+actions. Do not promise they will appear on every machine.
+
+### 2. Overview
+
+Click **Overview** or open:
+
+```text
+http://127.0.0.1:5173/overview
+```
+
+Panels:
+
+| Panel | What it means |
+| --- | --- |
+| Metric tiles | Counts and status for the generated V0 fixture stack. |
+| Recent FlowPulse observations | The latest observed FlowPulse-style records with receipt-derived transaction/log metadata. |
+| Verifier attention | Reports that need review, or an empty state when fixture reports are verified. |
+| Hardware risk | FlowRouter POC heartbeat records that are stale or risky in fixtures. Hardware is optional for this demo. |
+| Devnet block window | Deterministic local block and state-root view. |
+
+Say:
+
+```text
+FlowPulse is the observation spine. Contracts emit compact events; indexers and
+verifiers derive receipt facts such as transaction hash and log index after the
+receipt exists.
+```
+
+### 3. Flow Memory / Rootflow
+
+Click **Flow Memory** or open:
+
+```text
+http://127.0.0.1:5173/flowmemory
+```
+
+Say:
+
+```text
+This view turns observations, verifier reports, and roots into Flow Memory V0
+objects: MemorySignals, MemoryReceipts, RootfieldBundles,
+AgentMemoryViews, and RootflowTransitions.
+```
+
+Use this view to show parent/child state transitions and status vocabulary:
+
+```text
+observed, pending, finalized, verified, unresolved, failed, unsupported,
+reorged, offline, stale
+```
+
+### 4. FlowPulse And Rootfields
+
+Click **FlowPulse**:
+
+```text
+http://127.0.0.1:5173/flowpulse
+```
+
+Then click **Rootfields**:
+
+```text
+http://127.0.0.1:5173/rootfields
+```
+
+Say:
+
+```text
+Rootfields are namespaces and compact commitment state. They are not unlimited
+storage, and metadata/evidence URIs are pointers or arbitrary log strings, not
+raw model or artifact storage.
+```
+
+### 5. Work Lanes, Verifier, Devnet, Hardware, Alerts
+
+Click these only if time allows:
+
+| Route | What to show |
+| --- | --- |
+| `/work` | Work lanes and receipt status. |
+| `/verifier` | Verifier reports and reason codes. These are local/test reports, not a production verifier network. |
+| `/devnet` | Deterministic no-value local blocks and roots. |
+| `/hardware` | FlowRouter POC heartbeat/control-signal records. This is not manufactured or field-deployed hardware. |
+| `/alerts` | Operator warnings and recommended local actions. |
+
+### 6. Base Canary
+
+Click **Base canary** or open:
+
+```text
+http://127.0.0.1:5173/canary
+```
+
+Say:
+
+```text
+This route is intentionally separate from local fixture mode. It reviews a
+guarded Base canary read over known V0 canary addresses and a small explicit
+block range. It is visible on Base, but it is still a canary, not production
+approval.
+```
+
+Current committed canary fixture summary:
+
+| Field | Current value |
+| --- | --- |
+| Chain id | `8453` |
+| Read window | `45955500` to `45955540` |
+| Canary FlowPulse observations | `4` |
+| Rootfields | `1` |
+| Rootflow transitions | `4` |
+| Rejected logs | `0` |
+| Duplicates | `0` |
+| Contracts in canary artifact | `10` |
+
+Canary panels:
+
+| Panel | What it means |
+| --- | --- |
+| Canary boundary hero | The high-level warning: visible on Base, still gated for production. |
+| Reader command / review fixture / hard boundary strip | The exact reader shape, runtime fixture path, and no broad scan/no production/no real-funds boundary. |
+| Canary metrics | Counts from the committed canary fixture, including rejected logs and duplicates. |
+| Canary FlowPulse stream | The observed canary logs with block, pulse type, transaction hash, and log index. |
+| FlowPulse contracts | Canary contracts that emitted FlowPulse logs in the review fixture. |
+| Launch gates | Boundaries that remain before any production claim. |
+| Canary Rootflow state | Rootflow transitions reconstructed from the canary observations. |
+| Canary JSON | Full loaded canary dashboard payload for reviewer inspection. |
+
+If someone asks how to refresh canary data, show the documented command but do
+not run it unless the operator explicitly wants a live read and has approved the
+RPC endpoint and block range:
+
+```powershell
+npm run index:base-canary -- --acknowledge-mainnet-canary --rpc-url https://mainnet.base.org --address 0x2a7ADd68a1d45C3251E2F92fFe4926124654a97C --address 0x179Df6d52e9DeF5D02704583a2E4E5a9FF427245 --from-block 45955500 --to-block 45955540 --finalized-block 45955540
+npm run flowmemory:canary-dashboard
+```
+
+Boundary to say out loud:
+
+```text
+The guarded reader refuses broad scans and marks checkpoint output as not
+production-ready. The canary dashboard data is review evidence, not a
+production service.
+```
+
+## Recovery During A Live Demo
+
+### Workbench Opens But Says Fixture Fallback
+
+This is acceptable. Say:
+
+```text
+The local API is not detected, so the dashboard is showing deterministic
+fixtures. That is an intended fallback path.
+```
+
+To recover live local API mode, start another PowerShell window:
+
+```powershell
+cd E:\FlowMemory\flowmemory-main
+npm run control-plane:serve
+```
+
+Refresh the browser. The banner should change to **Local API detected.**
+
+### Control Plane Fails To Start
+
+Run:
+
+```powershell
+cd E:\FlowMemory\flowmemory-main
+npm install
+npm run launch:v0
+npm test --prefix services/control-plane
+npm run control-plane:serve
+```
+
+If the port is already in use:
+
+```powershell
+Get-NetTCPConnection -LocalPort 8787 -ErrorAction SilentlyContinue
+```
+
+Close the old PowerShell window that owns the service, or stop that process if
+you intentionally started it and no longer need it.
+
+### Workbench Does Not Open
+
+Run:
+
+```powershell
+npm install --prefix apps/dashboard
+npm run workbench:dev
+```
+
+Use the URL printed by Vite. If the browser is stale, refresh the page. If the
+dev server is wedged, press `Ctrl+C` in the workbench window and rerun the
+command.
+
+### Local State Looks Wrong
+
+Reset only ignored local devnet state:
+
+```powershell
+npm run flowchain:stop -- -ResetLocalState
+npm run flowchain:init
+npm run flowchain:start
+npm run flowchain:demo
+```
+
+This does not edit committed fixtures.
+
+### Canary Route Does Not Load
+
+Refresh dashboard fixtures:
+
+```powershell
+npm run flowmemory:canary-dashboard
+npm run sync:fixtures --prefix apps/dashboard
+npm run workbench:dev
+```
+
+If the canary JSON is stale, say it is the committed canary review fixture and
+point to:
+
+```text
+docs/DEPLOYMENTS/2026-05-13-base-canary-v0.md
+```
+
+Do not invent a newer canary status.
+
+## Launch-Day Checklist
+
+### Before The Demo
+
+- Confirm the intended branch and clean state:
+
+```powershell
+git fetch --all --prune
+git status --short --branch
+```
+
+- Check GitHub state:
+
+```powershell
+gh pr list --repo FlowmemoryAI/FlowMemory --state open
+gh issue list --repo FlowmemoryAI/FlowMemory --state open --limit 80
+```
+
+- Run the acceptance gate when prerequisites are present:
+
+```powershell
+npm run flowchain:full-smoke
+```
+
+- Generate demo state:
+
+```powershell
+npm run flowchain:init
+npm run flowchain:start
+npm run flowchain:demo
+npm run flowchain:export
+```
+
+- Start local API and workbench in separate windows:
+
+```powershell
+npm run control-plane:serve
+```
+
+```powershell
+npm run workbench:dev
+```
+
+- Open these browser routes:
+
+```text
+http://127.0.0.1:5173/
+http://127.0.0.1:5173/overview
+http://127.0.0.1:5173/flowmemory
+http://127.0.0.1:5173/canary
+http://127.0.0.1:5173/raw
+```
+
+### During The Demo
+
+- Keep private keys, seed phrases, RPC credentials, API keys, and webhook URLs
+  off screen.
+- Use the exact framing from this runbook.
+- If a reviewer asks what is live, distinguish local/private runtime state,
+  deterministic fixtures, and committed canary reader output.
+- If a reviewer asks whether it is production-ready, answer "no."
+- If a reviewer asks whether the canary is on Base, answer "yes, as a guarded
+  V0 canary deployment for testing only."
+- If a command fails, capture the first failing command and use
+  `docs/FLOWCHAIN_TROUBLESHOOTING.md`.
+
+### After The Demo
+
+Stop local windows with `Ctrl+C`, then record stopped state:
+
+```powershell
+npm run flowchain:stop
+```
+
+Capture handoff evidence:
+
+```powershell
+Get-Content -Raw devnet/local/smoke/flowchain-smoke-report.json
+Get-Content -Raw devnet/local/full-smoke/flowchain-full-smoke-report.json
+git status --short --branch
+```
+
+End the handoff with:
+
+- what was shown;
+- commands run;
+- whether full smoke passed or why it was skipped;
+- any failure and first failing command;
+- risks, assumptions, and follow-ups.

+The 2026-05-13 launch-candidate security boundary review lives in

+
+Current security conclusion:
+
+- Local/test V0 demos and guarded Base canary review are acceptable with

+- No production or mainnet-launch claim is approved.
+- Direct single-account ownership, owner allowlists, self-registration, and open

+- `BASE_SEPOLIA_DEPLOYER_KEY_HEX` is read from the local environment for the
+  Base Sepolia deploy wrapper, but the wrapper passes it to Foundry as a
+  command-line private key. That is a local/test caveat and a blocker for any
+  future production signing path.
+- The local encrypted test vault is no-value private/local tooling, not
+  production custody or audited key management.
+- The guarded Base mainnet canary reader is for documented canary addresses and
+  bounded block ranges only. It is not a broad production indexer.
+- `FlowMemoryAfterSwapHook` is a production-shaped hook candidate, not a
+  production Uniswap v4 hook deployment. Any future hook broadcast requires a
+  recorded salt/address, permission-bit review, PoolManager integration review,
+  source-verification plan, post-deploy read range, and go/no-go decision.

+# Launch-Candidate Security Boundary Review
+
+Date: 2026-05-13
+
+Reviewer role: Security Review Agent
+
+Result: pass for local/test V0 launch-candidate demos and guarded canary review.
+Result: fail for any production, mainnet-launch, custody, verifier-network,
+bridge, audited-cryptography, or production Uniswap hook claim.
+
+## Scope
+
+Reviewed the launch-candidate boundary across:
+
+- source-of-truth docs: `docs/START_HERE.md`,
+  `docs/FLOWMEMORY_HQ_CONTEXT.md`, `docs/CURRENT_STATE.md`,
+  `docs/SECURITY_MODEL.md`, `docs/MARKETING_CLAIMS_GUARDRAILS.md`,
+  `docs/PRODUCTION_READINESS_CHECKLIST.md`, and deployment/operator docs;
+- existing review docs under `docs/reviews/`;
+- contract boundary docs and selected contract surfaces for access-control
+  assumptions;
+- deployment, reader, canary, local wallet, and smoke scripts;
+- README and launch-facing claim surfaces.
+
+GitHub/source check: local `HEAD` and `origin/HEAD` both resolved to
+`98386b9e40c271c5bac2d41ba3a9010d9e9da36e` before edits.
+
+## Pass/Fail Matrix
+
+| Area | V0 result | Notes |
+| --- | --- | --- |
+| Source-of-truth consistency | Pass with caveat | Current docs consistently say V0/local/test, with a real Base mainnet canary documented as canary-only. README still has older "do not claim mainnet deployment" wording that should be clarified to "production mainnet deployment" in a later README-scoped task. |
+| Access control | Pass for V0, fail for production | Per-record owners, owner allowlists, self-registration, and open submission surfaces are documented. Direct deployer ownership, no multisig, no recovery, no timelock, and no decentralized verifier governance remain production blockers. |
+| Unsafe claims | Pass after guardrail expansion | Claim scanning now covers README, docs, contract docs, and marketing, and blocks more production/mainnet launch wording unless explicitly framed as blocked, not implemented, or out of scope. |
+| Secret handling | Pass for committed V0 surfaces, fail for production signing | `.gitignore`, CI secret checks, control-plane no-secret scanning, and canary reader outputs avoid committed credentials. The Base Sepolia deploy wrapper still passes a private key to `forge --private-key`, which is acceptable only as a local/test operator caveat. |
+| Local wallet boundary | Pass for local no-value tests | The encrypted local test vault excludes private keys from public exports and is exercised in ignored `devnet/local/` output. It is not production custody, wallet connect, or value-bearing key management. |
+| Deployment scripts | Pass for dry-run/testnet/canary boundaries | Base Sepolia deploy requires explicit env inputs. Base canary reading requires explicit acknowledgement, addresses, and small block ranges. Source verification redacts API key material. |
+| Base mainnet canary | Pass as canary-only | The documented canary is real Base mainnet activity, but artifacts and dashboard state mark `productionReady: false` and separate canary data from local fixture acceptance. |
+| Uniswap hook assumptions | Pass for V0, fail for production hook readiness | `FlowMemoryHookAdapter` is open/canary scaffold. `FlowMemoryAfterSwapHook` is PoolManager-gated and afterSwap-only, but there is no recorded mined hook address, deployment, PoolManager integration, source-verification plan, or go/no-go approval for production. |
+| Verifier/trust claims | Pass for local signed statements | V0 verifier reports and attestations are deterministic signed claims. They are not zk proofs, decentralized consensus, staking, slashing, or a production verifier network. |
+| Bridge and real funds | Pass for POC/canary-read boundary, fail for production bridge | `BaseBridgeLockbox` is test-only, owner-controlled, capped, and not trustless. Mainnet canary reads require real-funds acknowledgement and a small USD cap, but releases remain owner-controlled. |
+| URI/off-chain data boundary | Pass as documented caveat | `metadataURI` and `evidenceURI` are arbitrary log strings. Contracts do not enforce length, content type, resolvability, privacy, or short-pointer behavior. |
+
+## Blockers Before Any Production Claim
+
+These are launch blockers for production language, not blockers for local/test
+V0 demos:
+
+- Record an explicit go/no-go decision in `docs/DECISIONS/`.
+- Replace direct single-account operator ownership with a reviewed multisig or
+  comparable account-control policy, including rotation and recovery.
+- Separate deployer, worker admin, verifier admin, and emergency-response
+  authority.
+- Stop using command-line private-key broadcast for any production signing path;
+  require a safer signer or keystore/hardware-wallet flow.
+- Define verifier identity, signing policy, challenge lifecycle, finality,
+  replay policy, and verifier-set governance.
+- Complete and record source verification for every future deployed or
+  redeployed contract address.
+- For Uniswap v4, record the mined hook salt/address, hook permission bits,
+  PoolManager address, constructor args, init code hash, deployment block,
+  post-deploy reader range, and integration review.
+- Keep broad Base mainnet readers disabled unless a separate production indexer
+  design and incident-response plan are accepted.
+- Add URI/pointer policy if any public copy implies off-chain storage
+  enforcement, content availability, or privacy.
+- Keep bridge releases, real-funds flows, and custody out of public user paths
+  until a bridge threat model, release policy, caps, monitoring, and emergency
+  playbook are accepted.
+- Do not describe local wallet helpers as production custody or wallet support.
+- Do not describe current verifier reports as audited or fully trustless proofs.
+
+## Acceptable V0 Caveats
+
+The following are acceptable only with explicit local/test/canary framing:
+
+- Direct owner and owner-allowlist contracts for V0 commitment surfaces.
+- Self-registration registries when downstream docs treat registrations as
+  untrusted until verifier reports exist.
+- Open submission surfaces that emit reconstructable commitments but do not
+  custody funds or claim correctness.
+- Base Sepolia deployment dry runs and explicit broadcasts using local ignored
+  environment variables.
+- Guarded Base mainnet canary reads for documented canary addresses and small
+  explicit block ranges.
+- A Base mainnet canary deployment described as canary-only and
+  `productionReady: false`.
+- Local encrypted no-value test vaults stored under ignored local output paths.
+- Bridge POC observations and canary reads that do not claim production bridge
+  security or real user deposit readiness.
+- Fixture-backed dashboard and canary dashboard modes that stay visually and
+  semantically separate.
+
+## Concrete Guardrail Added
+
+`infra/scripts/check-unsafe-claims.mjs` now:
+
+- scans `contracts/` markdown boundary docs in addition to `README.md`,
+  `docs/`, and `marketing/`;
+- blocks unguarded positive claims for production launch, mainnet launch,
+  production-mainnet, production deployment, production verifier network,
+  production Uniswap hook, production bridge, production custody, and audited
+  status;
+- keeps existing allowances for lines or sections that clearly mark those
+  phrases as blocked, rejected, gated, not implemented, or out of scope.
+
+## Review Decision
+
+No production or mainnet-launch claim is approved.
+
+FlowMemory can proceed with V0 launch-candidate demos only if copy continues to
+say local/test, Base Sepolia, guarded Base mainnet canary, no-value devnet,
+fixture-backed dashboard, canary-only, and `productionReady: false` where
+applicable.
