# Continuity Plugin (MVP)

> 中文版：`README.zh-TW.md`

This package extracts the current approved-plan continuity hard gate into a small installable, testable OpenClaw plugin MVP.

The goal is not to reinvent workflow policy. The goal is to package the existing continuity evaluator, receipt contract, and force-recall adapter so other OpenClaw workspaces can reuse the same minimum integration.

## What this MVP currently provides

- continuity config validation
- dispatch receipt contract validation
- receipt file writing
- approved-plan continuity gate evaluation
- prompt block generation for the continuity gate
- a `force-recall` adapter that maps hook wrapper/planner output into continuity input

## Install location

Recommended location inside an OpenClaw workspace:

```text
<workspace>/plugins/continuity
```

With the current MVP integration, the related files normally look like this:

```text
<workspace>/
  hooks/
    force-recall/
      handler.ts
      HOOK.md

    test_force_recall_long_task_preflight.mjs

## Public surface

- `src/config/schema.mjs`
- `src/config/defaults.mjs`
- `src/continuity/evaluator.mjs`
- `src/continuity/receipt-validator.mjs`
- `src/continuity/receipt-store.mjs`
- `src/adapters/force-recall.mjs`
- `src/index.mjs`

`src/index.mjs` currently re-exports:

- `defaultConfig`
- `cloneDefaultConfig()`
- `validateContinuityConfig()` / `normalizeContinuityConfig()`
- `evaluateContinuity()` / `buildContinuityGateBlock()`
- `validateReceipt()` / `isValidReceipt()`
- `slugifyReceiptSegment()` / `buildReceiptFilename()` / `writeReceipt()`
- `buildApprovedPlanContinuityInput()`
- `createForceRecallContinuityAdapter()` / `runForceRecallContinuityAdapter()`

## Example config

Start from `examples/openclaw.continuity.example.json`:

```json
{
  "enabled": true,
  "planMatchers": ["approved-plan"],
  "legalTerminalStates": [
    "waiting_user",
    "blocked",
    "pending_verification"
  ],
  "receiptDir": "state/approved-plan-continuity",
  "requireRealDispatchReceipt": true,
  "allowReplyClosureWithoutDispatch": false,
  "debug": false,
  "adapter": {
    "forceRecall": {
      "enabled": true,
      "injectBlockLabel": "APPROVED_PLAN_CONTINUITY_GATE"
    }
  }
}
```

Defaults are defined in `src/config/defaults.mjs`.

## Hook integration

The primary MVP integration point is `hooks/force-recall/handler.ts`.

The current hook path is:

1. run long-task preflight / gate lock / auto-chain planner
2. dynamically load `plugins/continuity/src/index.mjs`
3. call `runForceRecallContinuityAdapter({ wrapperResult, autoChainPlanResult, config })`
4. prepend the returned block into `bodyForAgent`

The handler already contains the plugin path integration points. The key symbols are:

- `runForceRecallContinuityAdapter`
- `[APPROVED_PLAN_CONTINUITY_GATE]`

Minimal integration example:

```js
import plugin from './plugins/continuity/src/index.mjs';

const out = plugin.runForceRecallContinuityAdapter({
  config: plugin.defaultConfig,
  wrapperResult,
  autoChainPlanResult,
});

if (out?.block) {
  context.bodyForAgent = `${out.block}\n${context.bodyForAgent}`;
}
```

If you want a custom injected block label, override `adapter.forceRecall.injectBlockLabel`.

## Receipt contract

Minimum receipt shape:

- `planId`
- `currentTask`
- `nextDerivedAction`
- `dispatchedAt`
- `dispatchRunId`
- `childSessionKey`
- `replyClosureState`

Example from `examples/approved-plan-receipt.example.json`:

```json
{
  "planId": "example-plan",
  "currentTask": "task-01",
  "nextDerivedAction": {
    "kind": "delegate",
    "target": "subagent",
    "task": "placeholder"
  },
  "dispatchedAt": "2026-04-24T16:43:00+08:00",
  "dispatchRunId": "example-run",
  "childSessionKey": "session-placeholder",
  "replyClosureState": "pending_verification"
}
```

To persist a receipt:

```js
import { writeReceipt } from './src/index.mjs';

await writeReceipt({
  receiptDir: 'state/approved-plan-continuity',
  receipt,
});
```

## Smoke test / verification

At minimum, run:

```bash
cd plugins/continuity
npm test

cd /path/to/workspace
node scripts/test_force_recall_long_task_preflight.mjs
node --check hooks/force-recall/handler.ts
```

For a minimal plugin-only check, you can also run:

```bash
cd plugins/continuity
node test/continuity.smoke.test.mjs
```

## Install and apply steps for another OpenClaw workspace

1. Copy `plugins/continuity` into your workspace.
2. Ensure `hooks/force-recall/handler.ts` loads `plugins/continuity/src/index.mjs`.
3. Adjust the continuity config as needed, especially:
   - `planMatchers`
   - `legalTerminalStates`
   - `receiptDir`
   - `adapter.forceRecall.injectBlockLabel`
4. If your dispatch flow creates child runs/sessions, persist a real receipt.
5. Run the smoke test and the force-recall preflight test.
6. Confirm the agent prompt contains the continuity gate block and that dry-run dispatch alone does not pass the gate.

## Current limitations

- This is an MVP extraction of the **approved-plan continuity hard gate**, not a general workflow engine.
- The main adapter is `force-recall`; the package is not yet generalized into a multi-hook / multi-event integration layer.
- Config is still passed as module defaults plus caller input; there is not yet a full OpenClaw plugin installer/registration guide.
- The receipt store only writes files; it does not manage retention, cleanup, or indexing.
- The receipt validator checks the minimum contract only; it does not deeply validate every `nextDerivedAction` subtype.
- The documented install path assumes the existing `force-recall` preflight chain; if your workspace does not use that chain, you still need your own glue code.

## Notes

- Default legal terminal states are `waiting_user`, `blocked`, and `pending_verification`
- The evaluator preserves current behavior, including `missing_dispatch_receipt` and `missing_auto_next_dispatch`
- The adapter mirrors the continuity input mapping used by `hooks/force-recall/handler.ts`
- `HOOK.md` describes the plugin/hook adapter contract boundary, not the full installation guide
