# Continuity Plugin (MVP → generalized checkpoint)

> 中文版：`README.zh-TW.md`

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

The package still preserves the current approved-plan behavior, but it now moves one step closer to a more general **engine + adapter** structure:

- a host-agnostic continuity engine input/output contract
- the existing `force-recall` parity adapter
- a new `generic-preflight` adapter and manual runner for non-`force-recall` integration

## What this package 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
- a `generic-preflight` adapter that accepts host-agnostic continuity input directly
- a manual preflight runner for workspaces that do not use `force-recall`

## Install location

Recommended location inside an OpenClaw workspace:

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

Possible integration layouts now include both the original `force-recall` path and a more generic path:

```text
<workspace>/
  hooks/
    force-recall/
      handler.ts
      HOOK.md
  plugins/
    continuity/
      README.zh-TW.md
      README.md
      HOOK.md
      package.json
      examples/
      src/
      test/
  scripts/
    test_force_recall_long_task_preflight.mjs
```

## Public surface

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

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

- `defaultConfig`
- `cloneDefaultConfig()`
- `validateContinuityConfig()` / `normalizeContinuityConfig()`
- `normalizeContinuityEngineInput()`
- `createContinuityEngineResult()` / `createContinuityEngineContract()`
- `evaluateContinuity()` / `buildContinuityGateBlock()`
- `validateReceipt()` / `isValidReceipt()`
- `slugifyReceiptSegment()` / `buildReceiptFilename()` / `writeReceipt()`
- `buildApprovedPlanContinuityInput()`
- `createForceRecallContinuityAdapter()` / `runForceRecallContinuityAdapter()`
- `buildGenericContinuityInput()`
- `createGenericPreflightContinuityAdapter()` / `runGenericPreflightContinuityAdapter()`
- `runManualContinuityPreflight()`

## Host-agnostic engine contract

The generalized engine accepts a normalized continuity input with fields such as:

- `planId`
- `currentTask`
- `taskState`
- `nextDerivedAction`
- `replyClosureState`
- `dispatchReceipt`
- `nextTaskKnown`
- `sameApprovedPlan`
- `taskBoundaryStop`
- `highRiskStop`

Generalized adapters return a common contract:

- `input`
- `result`
- `evaluation`
- `block`
- `meta.adapterName`
- `meta.hostAgnostic`

See `src/continuity/types.md` for the concise contract notes.

## 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"
    },
    "genericPreflight": {
      "enabled": true,
      "injectBlockLabel": "APPROVED_PLAN_CONTINUITY_GATE"
    }
  }
}
```

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

## Integration path A: `force-recall`

The original MVP integration point remains `hooks/force-recall/handler.ts`.

```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}`;
}
```

## Integration path B: generic/manual preflight

If your workspace does **not** use `force-recall`, you can still install and use the plugin by calling the generalized adapter or the manual runner directly.

### Generic preflight adapter

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

const out = plugin.runGenericPreflightContinuityAdapter({
  config: plugin.defaultConfig,
  source: {
    planId: 'approved-plan-1',
    currentTask: 'task-3',
    taskState: 'complete',
    nextTaskKnown: true,
    sameApprovedPlan: true,
    taskBoundaryStop: true,
    nextTaskId: 'task-4',
    nextDerivedAction: { type: 'message_subagent', task: 'continue' },
    replyClosureState: 'completed',
    dispatchReceipt: null,
  },
});
```

### Manual runner

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

const out = plugin.runManualContinuityPreflight({
  config: plugin.defaultConfig,
  planId: 'approved-plan-1',
  currentTask: 'task-3',
  taskState: 'complete',
  nextDerivedAction: { type: 'message_subagent', task: 'continue' },
  replyClosureState: 'waiting_user',
});
```

If `out.block` is non-empty, prepend it into the prompt/body seen by the agent.

## Receipt contract

Minimum receipt shape:

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

To persist a receipt:

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

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

## Smoke test / verification

Required plugin verification:

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

If your workspace uses `force-recall`, also run:

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

## Install and apply steps for another OpenClaw workspace

1. Copy `plugins/continuity` into your workspace.
2. Choose one integration path:
   - `force-recall`: load `runForceRecallContinuityAdapter(...)`
   - no `force-recall`: call `runGenericPreflightContinuityAdapter(...)` or `runManualContinuityPreflight(...)`
3. Adjust config as needed, especially:
   - `planMatchers`
   - `legalTerminalStates`
   - `receiptDir`
   - `adapter.forceRecall.injectBlockLabel`
   - `adapter.genericPreflight.injectBlockLabel`
4. If your dispatch flow creates child runs/sessions, persist a real receipt.
5. Run plugin tests and the relevant workspace smoke path.
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 still centered on the approved-plan continuity hard gate, not a full general workflow engine.
- The generalized engine contract is intentionally minimal and conservative.
- `force-recall` remains the most battle-tested adapter.
- 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.

## 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 new generic path makes the plugin more reusable even without the `force-recall` hook
- `HOOK.md` describes the plugin/hook adapter contract boundary, not the full installation guide
