+  "criticality": "high",
+  "add_tags": ["internet-facing"],
+  "remove_tags": ["untriaged"]
+}
+```
+
+All patch fields are optional; omitted fields retain their current values. `add_tags` and `remove_tags` are deduplicated inside the transaction. Bulk edit, project binding, and batch deletion validate access to every requested asset first, so a missing or inaccessible ID fails the entire operation.

+
+{
+  "asset_ids": ["<primary-id>", "<duplicate-id>"],

+}
+```
+
+Every record being removed must share a domain, IP address, or Host with the primary asset. Existing primary values win, empty fields are filled from the other records, and tags are unioned. The caller needs permission to update the primary and delete the other assets.

+# Asset Management
+
+[中文](../zh-CN/asset-management.md)
+
+Asset management consolidates domains, IP addresses, ports, and services discovered through manual entry, network-space search engines, HTTP APIs, and Agent tasks into a maintainable baseline. It answers three questions: what assets exist, which assets have been assessed, and where risk is concentrated.
+
+> This feature is designed for security testing and attack-surface governance. It is not a replacement for a full enterprise CMDB. Add and scan only systems you own or are explicitly authorized to test.
+
+## Overview
+
+Asset management provides three main views:
+
+- **Overview**: asset totals, IPs, domains, ports, recent changes, scan coverage, and protocol distribution.
+- **Asset inventory**: identity, service details, source, tags, project ownership, responsibility and business metadata, scan history, and risk state.
+- **Reconnaissance**: search FOFA, ZoomEye, Quake, or Shodan and save confirmed results individually or in batches.
+
+Assets can launch single-target analysis or batch scans. After an Agent records findings and completes the scan callback, the inventory displays related vulnerability counts, risk level, and latest scan time.
+
+The overview can show the last 7, 30, or 90 days. It includes added/inactive asset trends, vulnerability discovery trends (including critical/high findings), total and 30-day scan coverage, never-scanned and stale counts, and the top eight protocols. Every statistic is restricted to the current user's accessible assets.
+
+## Asset fields
+
+An asset can include:
+
+- host, IP address, domain, port, and protocol;
+- page title and service or product fingerprint;
+- country/region, state/province, and city;
+- responsible person, department, business system, environment, and criticality;
+- source, source query, and tags;
+- active or inactive status;
+- project and owner;
+- first seen, last seen, created, and updated timestamps;
+- latest scan time and linked conversation, task queue, and subtask;
+- related vulnerability count and current risk level.
+
+At least one of `host`, `ip`, or `domain` is required.
+
+## Build an asset baseline
+
+### Add an asset manually
+
+Go to **Asset Management → Asset Inventory** and select **Add Asset**. Supported target forms include:
+
+```text
+https://example.com:8443
+example.com
+192.0.2.10:443
+[2001:db8::1]:443
+```
+
+The system attempts to identify the URL, domain, IP address, port, and protocol. You can then add a project, tags, title, service fingerprint, location, responsible person, department, business system, environment, criticality, and status.
+
+### Import from a spreadsheet
+
+Go to **Asset Management → Asset Inventory** and select **Bulk Import**:
+
+1. Download the XLSX (recommended) or CSV template.
+2. Enter assets in the `Assets` sheet without changing the header row.
+3. Choose the completed file or drop it onto the upload area.
+4. Review row-level validation. Duplicates, invalid values, and inaccessible projects are marked as errors.
+5. Select **Import valid rows**. Invalid rows are not submitted. When the file contains more than 100 rows, the preview shows the first 100 while submission processes every valid row.
+6. Review the created, updated, and skipped counts.
+
+Template columns:
+
+| Column | Required | Description |
+| --- | --- | --- |
+| `target` | Conditional | URL, domain, IPv4, IPv6, or a target with a port; required when `host`, `ip`, and `domain` are all empty |
+| `project` | No | Exact name or ID of an existing project; leave blank for no project |
+| `tags` | No | Comma, semicolon, or pipe-separated; up to 30 tags and 64 characters per tag |
+| `host` | Conditional | Full URL or host; may supplement `target` |
+| `ip` | Conditional | Valid IPv4 or IPv6 address |
+| `domain` | Conditional | Valid domain; internationalized domains are normalized |
+| `port` | No | `0-65535`; may be inferred from `target` |
+| `protocol` | No | Such as `http`, `https`, or `ssh`; may be inferred from a URL or common port |
+| `title` | No | Page title, up to 500 characters |
+| `server` | No | Service or product fingerprint |
+| `country` / `province` / `city` | No | Location metadata |
+| `responsible_person` | No | Responsible person, up to 255 characters |
+| `department` | No | Responsible department, up to 255 characters |
+| `business_system` | No | Owning business system, up to 255 characters |
+| `environment` | No | `production`, `staging`, `testing`, `development`, or `other` |
+| `criticality` | No | `critical`, `high`, `medium`, or `low` |
+| `status` | No | `active` or `inactive`; defaults to `active` |
+
+The parser recognizes the template's English headers and common Chinese aliases. Environment and criticality columns also accept their corresponding Chinese values. Automated exports should keep the English headers and enum values to avoid ambiguous mappings.
+
+Limits and behavior:
+
+- One XLSX/CSV file may contain up to 100,000 rows and be up to 100 MB.
+- One `/api/assets/import` request may contain up to 100,000 assets.
+- Later rows with the same “target + port + protocol” in one file are marked as duplicates and are not submitted.
+- The Web UI parses and previews the file; the server remains responsible for authorization, validation, normalization, deduplication, and transactional writes.
+- Existing assets receive non-empty incoming fields and a refreshed last-seen time instead of a duplicate record.
+- Bulk import requires `asset:write`. Referenced projects must also be accessible to the current user.
+- Do not remove the server-side row limit. Split larger datasets and import them during a low-traffic window.
+
+### Import from network-space search
+
+1. Configure the relevant API key in the configuration file or under **System Settings → Asset Management**. Environment variables are also supported: `FOFA_API_KEY`, `ZOOMEYE_API_KEY`, `QUAKE_API_KEY`, and `SHODAN_API_KEY`.
+2. Open **Asset Management → Reconnaissance**.
+3. Select the data source: FOFA, ZoomEye, Quake, or Shodan.
+4. Enter or generate a query for that source and confirm its scope.
+5. Run the query, select results whose ownership has been verified, and choose **Save Selected**.
+6. Review the created, updated, and skipped counts.
+
+Internet search results are not automatically your assets. Narrow the query with organization domains, certificates, network ranges, or product fingerprints, then verify authorization before saving results.
+
+## Normalization and deduplication
+
+Different sources may describe the same target in different forms. The system:
+
+- trims surrounding whitespace;
+- normalizes IP addresses, domains, and protocols to lowercase;
+- extracts hostname, protocol, and port from URL-like hosts;
+- fills default HTTP/HTTPS ports when omitted;
+- converts internationalized domains to ASCII/Punycode;
+- removes empty or duplicate tags;
+- supplies default source and status values.
+
+Assets use “target + port + protocol” as the service-level deduplication key. The preferred target is the domain, followed by the IP address, then the host. As a result, `80/http` and `443/https` on the same host remain separate assets.
+
+When an existing asset is imported again, non-empty incoming fields and the last-seen time are updated. Existing fields omitted by the new record and the original first-seen time are preserved.
+
+## Search, filters, and views
+
+Keyword search in the Web UI covers hosts, IP addresses, domains, titles, services, tags, responsible people, departments, and business systems. Status and project are the primary filters; advanced filters can combine:
+
+- risk level and minimum vulnerability count;
+- protocol, port, source, and exact tag;
+- scanned, never scanned, or not scanned for 30/60/90 days;
+- country/region, state/province, city, responsible person, department, and business system;
+- environment, criticality, first-seen dates, and last-seen dates;
+- sorting by last seen, latest scan, risk, vulnerability count, first seen, target name, or port.
+
+Sorting by latest scan time in ascending order places never-scanned assets first, making coverage gaps visible.
+
+Frequently used combinations can be saved as filter views. Saved views use the current browser's `localStorage`; they are not synchronized to the server, other browsers, or other users.
+
+The HTTP API and `query_assets` additionally support `max_vulnerabilities`, latest-scan time ranges, and allowlisted creation/update sort fields. HTTP lists allow up to 100 rows per page, while Agent queries allow up to 50.
+
+## Bulk maintenance and export
+
+After selecting assets, you can act on the current page or select every result matching the current filters. Cross-page selection resolves the filters again on the server and is limited to 10,000 assets; narrow the filters when the result exceeds that limit.
+
+Available actions:
+
+- **Bind project**: replace the project binding for all selected assets;
+- **Bulk edit**: change status, responsible person, department, business system, environment, and criticality, and add or remove tags;
+- **Create scan task / Send to chat**: apply one prompt template to the selected assets;
+- **Export CSV / XLSX**: export the currently selected rows in the browser, including ownership, risk, vulnerability count, and timestamp fields;
+- **Merge duplicates**: keep the first selected asset as primary, fill its empty fields from the other records, and union their tags;
+- **Batch delete**: permanently delete the selected assets.
+
+Bulk edit, project binding, and batch delete are all-or-nothing transactions. If any requested asset is missing or outside the caller's scope, the entire operation fails without a partial update.
+
+Merge is only allowed when every duplicate shares a domain, IP address, or Host with the primary asset, and accepts 2-100 selected records. Existing primary values win, tags are unioned subject to the 30-tag limit, and the other records are deleted. It requires both `asset:write` and `asset:delete`; confirm the primary record and the scan history you need to retain before merging.
+
+## Scanning and risk updates
+
+### Scan one asset
+
+Select **Scan** from the asset inventory. The system:
+
+1. creates a conversation containing the target and asset ID;
+2. links the conversation to the asset;
+3. prompts the Agent to inspect exposed services and authorized risks;
+4. stores confirmed findings with `record_vulnerability`;
+5. updates scan state with `complete_asset_scan`.
+
+Scan prompts support `{{asset_id}}`, `{{target}}`, `{{host}}`, `{{ip}}`, `{{domain}}`, and `{{port}}`. Adjust scope, ports, test intensity, and validation methods to match the authorization before starting.
+
+### Batch scans
+
+Select multiple assets and choose **Create Scan Task**. The system creates one subtask per asset and links each asset to its queue and subtask.
+
+The current defaults use manual scheduling, one concurrent task, and Eino single-Agent mode to limit load on targets and the local host. You must still confirm the test window, request rate, permitted validation methods, and approval requirements.
+
+### Risk calculation
+
+Asset risk is calculated dynamically from open vulnerabilities in the latest linked scan:
+
+- `critical`, `high`, `medium`, `low`, or `info`: an open finding at that level exists;
+- `normal`: the asset was scanned and has no open risk;
+- `unassessed`: no scan has completed.
+
+Resolved, false-positive, and ignored findings remain in historical counts but no longer increase the current risk level.
+
+## Agent tools
+
+Six built-in tools expose asset operations to Agents:
+
+- `create_asset`: create or deduplicate and update an asset;
+- `get_asset`: retrieve full details by ID;
+- `query_assets`: filter, sort, and paginate assets;
+- `update_asset`: partially update an asset;
+- `delete_asset`: delete an asset;
+- `complete_asset_scan`: record scan completion.
+
+`query_assets` returns 20 summaries by default and allows at most 50 per page. Use `get_asset` for full details so large inventories do not consume the model context.
+
+Both `create_asset` and `update_asset` accept responsibility and business metadata, and `query_assets` can filter by those fields. Agent writes go through the same normalization, validation, deduplication, and authorization checks as the HTTP API.
+
+## Access control
+
+Asset permissions are separated into:
+
+- `asset:read`: view assets and statistics;
+- `asset:write`: create, import, edit, and update scan state;
+- `asset:delete`: delete assets.
+
+Server-side authorization considers the asset owner, explicit resource assignments, the linked project, and permission scope (`all`, `assigned`, or `own`). When a conversation is linked to a project, Agent asset queries are restricted to that project and tool arguments cannot widen the boundary.
+
+Asset batch endpoint limits:
+
+- `POST /api/assets/import`: up to 100,000 assets per request;
+- `GET /api/assets/selection`: resolve up to 10,000 matching assets;
+- `POST /api/assets/scan-links`: up to 10,000 links per request;
+- `PUT /api/assets/bulk`: up to 10,000 asset IDs per request;
+- `PUT /api/assets/project-binding`: up to 10,000 asset IDs per request;
+- `POST /api/assets/batch-delete`: up to 10,000 asset IDs per request;
+- `POST /api/assets/merge`: merge 2-100 asset IDs per request.
+
+## Recommended workflow
+
+1. Define an explicitly authorized set of domains, IP addresses, or network ranges.
+2. Add a few critical targets manually and verify normalization and deduplication.
+3. Use tags to separate production, testing, critical-business, and internet-facing scopes.
+4. Configure one or more network-space search engines, begin with narrow queries, and verify ownership.
+5. Test scanning and vulnerability callbacks on one low-risk target.
+6. Use never-scanned and over-30-day filters to identify coverage gaps.
+7. After validating the workflow, expand gradually with small batch tasks.
+
+A small, verified baseline is usually more valuable than a large inventory with unclear ownership and inconsistent sources.

+# Tool Execution Governance
+
+[Back to English documentation](README.md)
+
+This document describes how CyberStrikeAI governs long-running tools, blocking MCP calls, oversized outputs, cancellation, and context restore. The goal is to preserve standard Agent/Eino tool semantics while preventing tool hangs, context blowups, oversized database records, and unsafe resume behavior.
+
+## Goals
+
+- **Keep the agent runner responsive**: tools may run for a long time, but the current runner waits only for a bounded interval.
+- **Allow long tasks to continue**: timeout returns an `execution_id`; later turns can call `wait_tool_execution`.
+- **Support cancellation**: users and agents can cancel a running execution.
+- **Keep DB and agent views identical**: the database stores the same canonical capped result returned to the agent.
+- **Protect resume paths**: resume uses model-facing traces and caps historical oversized tool traces.
+- **Isolate external MCP failures**: external MCP servers are protected by per-server concurrency limits, global concurrency limits, and circuit breakers.
+
+## Execution Model
+
+Tool calls still appear to Eino/Agent as standard tool invocations, but the blocking work runs in a worker:
+
+```text
+Agent calls tool
+  -> ExecutionService creates execution
+  -> worker runs the real MCP/tool call
+  -> Agent bounded wait
+       -> completed: return tool result
+       -> still running: return execution_id, worker continues in background
+```
+
+This prevents MCP servers, `exec`, `sqlmap`, `nmap`, `nuclei`, and similar long-running tools from binding the current runner indefinitely.
+
+## Execution Statuses
+
+| Status | Meaning |
+|---|---|
+| `queued` | Execution exists and is waiting for a worker or concurrency slot |
+| `running` | Worker is executing |
+| `background_running` | UI display state: agent stopped waiting, background worker continues |
+| `completed` | This tool call completed |
+| `failed` | The tool actually failed |
+| `cancelled` | User, agent, or session cleanup cancelled the execution |
+| `hard_timeout` | The tool exceeded its hard timeout |
+| `orphaned` | A persisted running execution no longer has a runtime worker |
+
+Important: when `wait_tool_execution` reaches `timeout_seconds` and the target execution is still running, the wait call itself is a completed observation, not a failed tool execution.
+
+## Control Tools
+
+| Tool | Purpose |
+|---|---|
+| `get_tool_execution` | Read current execution state |
+| `wait_tool_execution` | Wait for a selected execution for a bounded interval |
+| `cancel_tool_execution` | Cancel a selected execution |
+
+Typical flow:
+
+```text
+1. Call a long-running tool such as exec/sqlmap/nmap
+2. After tool_wait_timeout_seconds, receive execution_id
+3. Agent can continue reasoning, use other tools, or call wait_tool_execution
+4. If still incomplete, continue waiting or call cancel_tool_execution
+```
+
+## Cancellation and Session Cleanup
+
+- User stop cancels running tools for the current conversation.
+- Normal session end cancels remaining running tools for the current conversation.
+- Interrupt-and-continue style flows do not mass-cancel tools.
+- Conversation-scoped cancellation avoids killing tools from other conversations.
+
+## External MCP Isolation
+
+External MCP servers can hang, disconnect, or return failures. CyberStrikeAI uses three protections:
+
+| Capability | Config | Description |
+|---|---|---|
+| Per-server concurrency | `external_mcp_max_concurrent_per_server` | Max simultaneous calls for one external MCP server |
+| Global concurrency | `external_mcp_max_concurrent_total` | Max simultaneous external MCP calls across all servers |
+| Circuit breaker | `external_mcp_circuit_failure_threshold` / `external_mcp_circuit_cooldown_seconds` | Temporarily fast-fails a server after repeated failures |
+
+Recommended defaults:
+
+```yaml
+agent:
+  external_mcp_max_concurrent_per_server: 2
+  external_mcp_max_concurrent_total: 16
+  external_mcp_circuit_failure_threshold: 3
+  external_mcp_circuit_cooldown_seconds: 60
+```
+
+## Output Governance
+
+CyberStrikeAI uses `multi_agent.eino_middleware.reduction_max_length_for_trunc` as the unified tool result cap. The example configuration uses 50000 bytes.
+
+```yaml
+multi_agent:
+  eino_middleware:
+    reduction_enable: true
+    reduction_max_length_for_trunc: 50000
+```
+
+Coverage:
+
+| Channel | Behavior |
+|---|---|
+| Agent-facing tool result | Uses the canonical capped result |
+| DB / monitor storage | Stores the same canonical result |
+| `get_tool_execution` / `wait_tool_execution` | Reads the same canonical result |
+| Eino `execute` / filesystem monitor records | Capped before completion is persisted |
+| Non-streaming `exec` stdout/stderr | Source-side bounded buffer |
+| Streaming `exec` stdout/stderr | Streamed UI output is also bounded |
+| PTY execution path | Uses the same output cap |
+| Frontend detail modal | Has an additional UI display cap |
+
+When the cap is reached, the full output is written to a local trunc file and the agent-facing payload becomes a `<persisted-output>` notice (with absolute path) that fits inside the configured budget.
+
+Example:
+
+```text
+<persisted-output>
+Output too large (200000). Full output saved to: /path/to/tmp/reduction/conversations/<id>/trunc/<execution_id>
+Use read_file with offset/limit to read parts of the file.
+Preview (first …):
+…
+
+Preview (last …):
+…
+
+</persisted-output>
+```
+
+The current strategy is “spill full text to disk + bounded preview in context.” Agents can recover the original via `read_file`.
+
+## Database and Resume Context
+
+New results are written through this path:
+
+```text
+tool completes
+  -> NormalizeToolResultForStorage
+  -> update in-memory execution
+  -> persist to DB
+  -> return to Agent
+```
+
+So, under normal operation, the DB stores exactly the result returned to the agent.
+
+Resume uses `LastAgentTraceInput`, which is the model-facing trace that actually reached ChatModel, not raw event accumulation. The restore path also caps historical tool content to prevent context blowups from:
+
+- pre-upgrade DB records that contain raw large output,
+- manual imports or migrations,
+- lowering the configured cap from a larger value,
+- future bypasses that accidentally skip canonicalization.
+
+## Recommended Configuration
+
+For long-running security tasks:
+
+```yaml
+agent:
+  max_iterations: 800

+
+| Parameter | Recommended | Notes |
+|---|---:|---|
+| `max_iterations` | `300-1000` | Very large values weaken loop protection |
+| `tool_timeout_minutes` | `60` | Hard timeout for tools such as sqlmap |
+| `tool_wait_timeout_seconds` | `30-60` | Agent wait bound before returning `execution_id` |
+| `shell_no_output_timeout_seconds` | `600-1200` | Kills silent hangs |
+| `reduction_max_length_for_trunc` | `50000` | Unified tool result cap |
+
+Do not make `tool_wait_timeout_seconds` very large by default. Long tasks should continue in workers and be observed by `execution_id`, rather than blocking one turn for several minutes.
+
+## Testing
+
+Long-task test prompt:
+
+```text
+Call exec to run sleep 120. If it is not done after 10 seconds, do not keep waiting; report execution_id, call wait_tool_execution for 5 seconds, then cancel_tool_execution if still incomplete and report final status.
+```
+
+Large-output test prompt:
+
+```text
+Call exec to run: python3 - <<'PY'
+print("A" * 200000)
+PY
+Then show the tool result length and whether it contains the truncation marker.
+```
+
+Expected behavior:
+
+- The initial long task returns an `execution_id` and status `running` or UI `background_running`.
+- `wait_tool_execution` timing out while the target is still running is not displayed as a tool failure.
+- Large output never exceeds `reduction_max_length_for_trunc`.
+- DB, monitor details, and agent continuation use the same capped result.
+
+## Boundaries
+
+- CyberStrikeAI cannot control how a remote external MCP server collects output internally; it caps results after they enter CyberStrikeAI and protects calls with concurrency limits and circuit breakers.
+- Oversized tool output is spilled to local `tmp/reduction/.../trunc/<id>` (or `reduction_root_dir`) before truncation; the bounded result includes an absolute path for `read_file`.

-# Local Workflow Package MVP 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:** Add secure, deterministic single-workflow ZIP export plus two-step, idempotent local package import without changing existing workflow APIs.
-
-**Architecture:** `internal/workflow/package` owns package format, deterministic ZIP construction, archive inspection and import orchestration. `internal/database` owns SQLite schema, lifecycle state and the one transaction that rechecks the inspection snapshot, changes `workflow_definitions`, persists the import result and consumes the inspection. `internal/handler` maps the approved REST contract to these services and app routing/RBAC remains the enforcement boundary.
-
-**Tech Stack:** Go, Gin, SQLite via `github.com/mattn/go-sqlite3`, archive/zip, SHA-256, existing Eino `ValidateGraphJSON`.
-
-## Global Constraints
-
-- Backend only: do not modify `web/templates`, `web/static`, i18n, or any other frontend file.
-- Support exactly one `workflows/*.json` item; never execute package contents.
-- Request ZIP maximum is 10 MiB and extracted total maximum is 20 MiB.
-- Keep `workflow_definitions.version` local: create/rename is 1 and overwrite is the existing local version plus one.
-- Use `workflow:read` only for export, `workflow:write` for every inspection/import route, and require existing RBAC `all` scope for package mutations.
-- Preserve existing CRUD, validate, dry-run and run API response formats.
-
----
-
-### Task 1: Package format, canonical hashes and deterministic export
-
-**Files:**
-- Create: `internal/workflow/package/manifest.go`
-- Create: `internal/workflow/package/exporter.go`
-- Test: `internal/workflow/package/exporter_test.go`
-
-**Interfaces:**
-- Produces: `Export(database.WorkflowDefinition) ([]byte, ExportMetadata, error)`, `InspectArchive(context.Context, []byte) (*InspectionResult, error)`, and typed package errors exposing `Code`, safe `Message`, and safe `Details`.
-- Consumes: `database.WorkflowDefinition` and the existing graph JSON fields only.
-
-- [ ] **Step 1: Write failing package tests.** Cover two identical exports producing byte-identical ZIPs, lower-case `sha256:` hashes, `manifest.json`/`checksums.sha256`/one workflow entry, and source revision equal to the source workflow's local version.
-- [ ] **Step 2: Run the package test.** Run `go test ./internal/workflow/package -run 'TestExport'`; expected failure is missing package export symbols.
-- [ ] **Step 3: Implement canonical JSON and exporter.** Canonicalize JSON with `Decoder.UseNumber`, hash canonical graph JSON and canonical item JSON, derive a stable package id and fixed ZIP metadata, then write entries in lexical order.
-- [ ] **Step 4: Run the package test.** Run `go test ./internal/workflow/package -run 'TestExport'`; expected result is PASS.
-
-### Task 2: Safe package inspection and validation
-
-**Files:**
-- Create: `internal/workflow/package/inspector.go`
-- Test: `internal/workflow/package/inspector_test.go`
-
-**Interfaces:**
-- Consumes: ZIP bytes and `workflow.ValidateGraphJSON(context.Context, string)`.
-- Produces: validated manifest/workflow payload, package/content/graph hashes, node/edge counts, and contract error codes without archive paths.
-
-- [ ] **Step 1: Write failing inspector tests.** Use an exported valid package and assert accepted parsing; add independent cases for path traversal, duplicate names, symlink entries, undeclared files, checksum mismatch, two workflow entries, extracted-size overflow, invalid manifest and invalid graph.
-- [ ] **Step 2: Run the inspector test.** Run `go test ./internal/workflow/package -run 'TestInspect'`; expected failure is missing inspection implementation.
-- [ ] **Step 3: Implement archive checks before parsing.** Reject non-exact paths, duplicate names, links, unexpected entries and declared/actual oversized extraction; validate checksums and Manifest 1.0; require exactly one declared workflow entry; then reuse `ValidateGraphJSON`.
-- [ ] **Step 4: Run the inspector test.** Run `go test ./internal/workflow/package -run 'TestInspect'`; expected result is PASS.
-
-### Task 3: SQLite package state, lifecycle, and transactional application
-
-**Files:**
-- Modify: `internal/database/database.go`
-- Create: `internal/database/workflow_package.go`
-- Test: `internal/database/workflow_package_test.go`
-
-**Interfaces:**
-- Produces: inspection create/read/expiry methods, `ApplyWorkflowPackageImport` and `PurgeWorkflowPackageLifecycle(time.Time)`.
-- Consumes: primitive database request structs carrying inspected payload and immutable conflict snapshot; no browser-supplied workflow JSON.
-
-- [ ] **Step 1: Write failing DB tests.** Assert migration tables/indexes exist; inspection expiry transitions to `expired`; first successful application consumes inspection; same actor/key/same hash returns stored import; same key/different hash rejects; changed target snapshot rejects; overwrite increments local version; create and rename start at version 1; rollback leaves workflow/import/inspection unchanged on failure.
-- [ ] **Step 2: Run the DB test.** Run `go test ./internal/database -run 'TestWorkflowPackage'`; expected failure is missing migration and methods.
-- [ ] **Step 3: Add exact DDL and transactional repository method.** Add the two contract tables and indexes to `initTables`; in one `BEGIN` transaction recheck owner/status/expiry/idempotency/snapshot, apply the allowed action, insert import row, mark inspection consumed, and commit. Add 24-hour expired-inspection and 90-day import cleanup.
-- [ ] **Step 4: Run the DB test.** Run `go test ./internal/database -run 'TestWorkflowPackage'`; expected result is PASS.
-
-### Task 4: Import orchestration, HTTP handlers, audit and routes
-
-**Files:**
-- Create: `internal/workflow/package/importer.go`
-- Create: `internal/handler/workflow_package.go`
-- Modify: `internal/handler/workflow.go`
-- Modify: `internal/app/app.go`
-- Modify: `internal/security/rbac_middleware.go`
-- Test: `internal/handler/workflow_package_test.go`
-
-**Interfaces:**
-- Consumes: authenticated `security.Session`, `Idempotency-Key`, multipart `file`, database package state, and typed package errors.
-- Produces: contract response envelopes, `application/zip` export headers, cache invalidation after committed writes, and audit events in category `workflow_package`.
-
-- [ ] **Step 1: Write failing handler/RBAC tests.** Cover 403 mapping for read/write permissions, 10 MiB file limit, export headers/404, creator-only inspection/import reads, 201 first apply/200 idempotent replay, contract error body/status, and the existing validate/dry-run/runs routes still resolving.
-- [ ] **Step 2: Run the handler test.** Run `go test ./internal/handler -run 'TestWorkflowPackage'`; expected failure is missing routes/handlers.
-- [ ] **Step 3: Implement service and handlers.** Limit upload bytes before multipart parsing; persist only validated payload; perform request-hash and action validation in importer; map package errors to approved statuses; invalidate the compiled cache only after commit; record export/inspect/import success and failure audits.
-- [ ] **Step 4: Register and authorize routes.** Register exact paths `GET /workflows/:id/package`, `POST|GET /workflow-package-inspections`, and `POST|GET /workflow-package-imports`; make the route mapper explicit and treat inspection/import POSTs as process-global workflow mutations.
-- [ ] **Step 5: Run focused handler tests.** Run `go test ./internal/handler -run 'TestWorkflowPackage'`; expected result is PASS.
-
-### Task 5: Lifecycle wiring and final verification
-
-**Files:**
-- Modify: `internal/app/app.go`
-- Test: the tests from Tasks 1-4
-
-- [ ] **Step 1: Write the failing lifecycle wiring test or startup-level assertion.** Assert startup invokes package lifecycle cleanup and that the retention loop has no workflow-definition side effect.
-- [ ] **Step 2: Implement startup cleanup/loop.** Invoke `PurgeWorkflowPackageLifecycle(time.Now().UTC())` at startup and start an hourly package lifecycle loop after the database is ready.
-- [ ] **Step 3: Run format and focused verification.** Run `gofmt -w` only on changed Go files, `go test ./internal/workflow/package`, `go test ./internal/database -run 'TestWorkflowPackage'`, `go test ./internal/handler -run 'TestWorkflowPackage'`, and `git diff --check`.
-- [ ] **Step 4: Run compatible regression verification.** Run `go test ./internal/database ./internal/handler ./internal/workflow` in an environment with the required C compiler, then inspect `git diff --check` and `git status --short` before committing.
-- [ ] **Step 5: Commit verified files.** Run `git add internal/workflow/package internal/database/database.go internal/database/workflow_package.go internal/handler/workflow.go internal/handler/workflow_package.go internal/security/rbac_middleware.go internal/app/app.go docs/superpowers/plans/2026-07-13-local-workflow-package-mvp.md` followed by `git commit -m "feat: add local workflow package mvp"`.

-# 本地图编排策略包 MVP：API 与数据模型契约 v1
-
-> 本文是 [本地图编排策略包 MVP 设计](2026-07-13-local-workflow-package-mvp-design.md) 的实现前契约。前端与后端以本文的路径、字段、枚举、状态码和错误码为准；未经版本升级不得改变既有字段语义。
-
-## 1. 范围与不变式
-
-- 仅支持一个工作流的本地 `.csapkg.zip` 包。
-- 仅处理 `workflow_definitions`；不导入 Role、Skill、MCP 配置、运行记录或任何可执行文件。
-- 导入固定为“上传预检”和“确认应用”两步。预检不修改 `workflow_definitions`。
-- 现有工作流 CRUD、`/validate`、`/dry-run`、运行 API 和 `workflow_definitions` 表结构保持兼容。
-- 已有 `workflow_definitions.version` 始终是目标实例本地修订号：新建导入从 `1` 开始；覆盖导入由现有本地版本递增；包内 `source_revision` 只用于展示和审计。
-
-## 2. 统一约定
-
-### 2.1 认证与权限
-
-所有 API 均位于现有受保护的 `/api` 路由组。
-
-| 接口 | 所需权限 |
-|---|---|
-| 导出包 | `workflow:read` |
-| 创建或读取预检 | `workflow:write` |
-| 应用或读取导入结果 | `workflow:write` |
-
-预检会保存短期、已验证的工作流载荷，故不把它降级为只读权限。`created_by` / `actor_user_id` 取当前已认证会话的 `UserID`。
-
-RBAC 路由映射必须显式新增：`GET /workflows/:id/package` 映射 `workflow:read`；`/workflow-package-inspections` 与 `/workflow-package-imports` 的所有 MVP 路由映射 `workflow:write`。它们与既有工作流定义同属全局资产，写操作仅允许现有 RBAC 的 `all` 资源范围。
-
-### 2.2 错误响应
-
-新接口统一使用如下错误响应；不改变旧工作流 API 的 `{"error":"..."}` 兼容格式。
-
-```json
-{
-  "error": {
-    "code": "WFPKG_ID_CONFLICT",
-    "message": "目标实例已存在同 ID 工作流，请选择处理策略",
-    "details": {
-      "workflow_id": "web-src-hunting"
-    }
-  }
-}
-```
-
-`details` 仅包含可安全展示的结构化信息，不返回 Zip 路径、服务端文件路径、Token 或内部堆栈。
-
-### 2.3 时间与哈希
-
-- 所有时间字段使用 RFC 3339 UTC 字符串。
-- 哈希固定为小写十六进制 `sha256:<64-hex>`。
-- `graph_hash` 是对规范化 `graph_json` 的 SHA-256；`content_hash` 是工作流包项的 SHA-256。
-
-## 3. REST API
-
-### 3.1 导出单工作流包
-
-```http
-GET /api/workflows/{id}/package
-Accept: application/zip

-
-语义：从当前 `workflow_definitions` 行生成 `.csapkg.zip`。只读、幂等、无确认、无数据库写入。

-
-动作与 inspection 状态的合法组合：
-

-| `id_conflict` | `rename` | 以 `new_workflow_id` 新建副本，version 为 1。 |
-
-后端在应用事务开始前必须重新读取目标工作流并比较 inspection 中记录的冲突快照；若本地内容在预检后变化，返回 `409 WFPKG_CONFLICT_CHANGED`，前端必须重新预检。

-
-### 4.1 表职责与生命周期
-
-| 表 | 职责 | 保留规则 |
-|---|---|---|
-| `workflow_package_inspections` | 保存已验证的 Manifest、单工作流载荷、冲突快照和前端恢复所需摘要；不保存原始 Zip。 | `expires_at` 为创建后 30 分钟；到期改为 `expired`；清理任务可在 24 小时后删除。 |
-| `workflow_package_imports` | 导入结果、幂等键和应用记录。 | 保留 90 天；删除不影响既有审计日志。 |
-
-inspection 创建时写入 `workflow_payload_json`，应用时只读取该已验证载荷，不信任浏览器重新提交的工作流内容。`inspection_json` 是 3.2 成功响应中的安全摘要快照。
-
-### 4.2 导入事务
-
-导入应用必须在一个 SQLite 事务中完成以下操作：
-
-1. 校验 inspection 所属用户、状态、有效期与幂等键。
-2. 再次读取目标 `workflow_definitions`，验证冲突快照未变化。
-3. 按 action 新建、覆盖、重命名或保持现有工作流。
-4. 新增 `workflow_package_imports` 成功行，并把 inspection 改为 `consumed`。
-5. 提交事务；提交后失效工作流编译缓存并写审计日志。
-
-任一步失败必须回滚工作流、导入行和 inspection 状态。`workflow_package_imports.result='failed'` 仅在能安全独立记录失败时写入，绝不替代事务回滚。
-
-## 5. 审计契约
-
-复用现有 `audit_logs`，不在包表中复制审计全文：
-
-| 事件 | category | action | resource |
-|---|---|---|---|
-| 导出成功 | `workflow_package` | `export` | `workflow/{id}` |
-| 预检成功 | `workflow_package` | `inspect` | `inspection/{id}` |
-| 预检失败 | `workflow_package` | `inspect` | 无资源 ID；detail 仅含错误码与包 hash |
-| 应用成功 | `workflow_package` | `import` | `workflow/{resulting_workflow_id}` |
-| 应用失败 | `workflow_package` | `import` | `inspection/{id}` |
-
-## 6. 前后端并行边界
-
-前端可依据本文直接完成：下载按钮、文件上传、预检结果页、冲突动作选择、`confirm_overwrite` 二次确认、导入结果页和错误码国际化。
-
-后端可依据本文直接完成：路由、Handler、包解析服务、SQLite 迁移、事务、RBAC 映射、审计和单元/集成测试。
-
-前端不得自行解析 Zip、计算最终冲突结论或直接提交工作流 JSON；后端是 Manifest、哈希、图校验、冲突复查和导入结果的唯一权威。

-# 本地图编排策略包 MVP 设计
-
-## 决策摘要
-
-本期只交付本地图编排策略管理，不接入公共市场、远程仓库、发布上传、账号、评分或订阅能力。目标是先建立稳定的工作流包格式和安全导入闭环；未来市场仅复用该包格式和本地安装器。
-
-## 目标与非目标
-
-目标：用户可将单个工作流导出为可离线传输、可审查的包，并在另一实例中完成预检后显式导入。
-
-本期非目标：
-
-- 批量导出、批量导入、按标签或角色筛选。
-- 角色、Skill、工具元数据的实际导出或安装。
-- 远程仓库配置、策略市场、下载、上传和发布者身份。
-- 自动合并、三方 diff、跨实例 SemVer 升级、降级和回滚。
-- 工作流运行记录、会话、项目数据、MCP 密钥或任何可执行载荷。
-
-## 当前基础
-
-- 工作流保存在 SQLite 的 `workflow_definitions`，包含 `id`、`name`、`description`、整型 `version`、`graph_json`、`enabled`。
-- 保存前已有严格的 `ValidateGraphJSON` 校验；MVP 导入必须复用它。
-- 当前工作流 CRUD、`/validate`、`/dry-run` 和运行 API 不改变。
-- 角色和 Skill 分别存放于 `roles/`、`skills/`，本期不写入这两个目录。
-
-## 用户流程
-
-### 导出
-
-1. 用户在图编排详情页选择“导出”。
-2. 系统读取单个工作流定义，生成 `.csapkg.zip`。
-3. 用户下载包并可解压审查 JSON 与 Manifest。
-
-### 导入
-
-1. 用户在图编排列表页选择“导入本地包”。
-2. 系统上传并解析 Zip，但不写入数据库。
-3. 系统检查包结构、文件哈希、工作流 JSON，并调用 `ValidateGraphJSON`。
-4. 用户查看工作流名称、ID、节点/边数量、`graph_json` hash 和冲突结果。
-5. 用户确认“创建”或在冲突时选择“保留本地 / 覆盖 / 另存为新 ID”。
-6. 系统写入工作流、失效编译缓存、写入审计日志并返回结果。
-
-导入始终为两步：预检不会写入；仅确认后的应用步骤会改变本地工作流。缺少本期未处理的工具依赖时可显示提示，但不得阻止仅保存定义的导入。
-
-## 包格式
-
-文件扩展名为 `.csapkg.zip`，解压后保持人类可读：
-
-```text
-web-src-hunting-1.0.0.csapkg.zip
-├─ manifest.json
-├─ checksums.sha256
-└─ workflows/
-   └─ web-src-hunting.json
-```
-
-`manifest.json` 示例：
-
-```json
-{
-  "package_format": "cyberstrikeai.workflow-package",
-  "format_version": "1.0",
-  "package_id": "pkg_01JWEBHUNT",
-  "created_at": "2026-07-13T10:00:00Z",
-  "items": [
-    {
-      "type": "workflow",
-      "path": "workflows/web-src-hunting.json",
-      "source_id": "web-src-hunting",
-      "source_revision": 18,
-      "content_hash": "sha256:...",
-      "graph_hash": "sha256:..."
-    }
-  ]
-}
-```
-
-`workflows/*.json` 保留现有工作流字段。现有整型 `version` 继续作为本地修订号；MVP 不引入 SemVer，也不将版本解释为跨实例升级语义。
-
-## 冲突规则
-
-| 目标状态 | 默认行为 | 可选动作 |
-|---|---|---|
-| 本地不存在同 ID | 创建 | 无 |
-| 本地存在同 ID | 保留本地并报告冲突 | 覆盖、另存为新 ID、取消 |
-| 包内容 hash 与本地一致 | 跳过，视为幂等成功 | 无 |
-
-覆盖是破坏性操作，必须二次确认。另存为新 ID 时仅修改导入副本 ID，不修改任何角色绑定。
-
-## 后端边界
-
-新增 `internal/workflow/package` 包：
-
-- `manifest.go`：包格式、JSON 解析和版本兼容。
-- `exporter.go`：从 `workflow_definitions` 生成 Zip。
-- `inspector.go`：安全解压、哈希校验、结构校验与 `ValidateGraphJSON` 复用。
-- `importer.go`：冲突策略、数据库写入和编译缓存失效。
-
-建议新增 API：
-
-| API | 语义 | 写入 / 确认 |
-|---|---|---|
-| `POST /api/workflow-packages/exports` | 生成并下载单工作流包 | 无写入；无需确认 |
-| `POST /api/workflow-packages/inspections` | 上传并预检包 | 无写入；无需确认 |
-| `POST /api/workflow-package-imports` | 创建并应用导入计划 | 有写入；覆盖时需确认 |
-
-现有 API 不变。权限建议沿用 `workflow:read` 用于导出，`workflow:write` 用于导入；若后续需要细粒度授权，再拆出 `workflow:export`、`workflow:import`。
-
-## 安全与审计
-
-- 仅允许 Manifest 与声明的 JSON 文本；拒绝 Zip 路径穿越、重复条目、软链接、超大解压和未知文件。
-- 校验每个包项 SHA-256。
-- 不导出或导入密钥、Token、MCP 连接配置、运行记录和可执行文件。
-- 预检与实际导入分别写审计日志；应用记录包 hash、工作流 ID、策略和结果。
-
-## 前端范围
-
-- 图编排列表页：增加“导入本地包”。
-- 图编排详情页：增加“导出”。
-- 导入 Modal：上传、预检结果、冲突策略和确认应用。
-- `workflows.js` 负责调用新 API；不增加策略市场、远程仓库或发布 UI。
-
-## 验收与测试
-
-- 导出 `web-src-hunting` 后可解压并审查 Manifest 与完整工作流 JSON。
-- 导入包在确认前不改变数据库。
-- 合法图可创建；非法 DAG 或节点参数由 `ValidateGraphJSON` 拒绝。
-- 同 ID 默认不覆盖；覆盖须确认；另存生成新 ID。
-- 包 hash 不匹配、路径穿越、未知文件、超限文件均被拒绝。
-- 成功导入后工作流可由现有 GET API 读取，且编译缓存已失效。
-
-## 后续扩展边界
-
-v1 可增加批量导入导出、Role/Skill 可选项、工具依赖展示与导入历史。v2 可基于同一 `.csapkg.zip` 增加语义标识、SemVer、升级 diff、三方合并与回滚。公共策略市场、远程仓库和发布上传属于 v3 之后的独立子项目，不进入本期实现。

+# 资产管理
+
+[English](../en-US/asset-management.md)
+
+资产管理用于将手工录入、网络空间测绘搜索、HTTP API 和 Agent 任务中发现的域名、IP、端口与服务统一归档，形成可持续维护的资产基线。它关注三个问题：当前拥有哪些资产、哪些资产已经检查、风险集中在哪里。
+
+> 资产管理面向安全测试和攻击面治理，不替代完整的企业 CMDB。仅可录入和扫描自有系统或已获得明确授权的目标。
+
+## 功能概览
+
+资产管理包含三个主要入口：
+
+- **资产概览**：统计资产总量、IP、域名、端口、近期变化、扫描覆盖率和协议分布。
+- **资产库**：维护资产身份、服务信息、来源、标签、项目归属、责任与业务属性、扫描记录和风险状态。
+- **信息收集**：查询 FOFA、ZoomEye、Quake 或 Shodan，并将确认归属的结果单条或批量写入资产库。
+
+资产可以进一步发起单目标分析或批量扫描。Agent 保存漏洞并完成扫描回写后，资产列表会同步展示相关漏洞数量、风险等级和最近扫描时间。
+
+概览支持切换最近 7、30 或 90 天，展示新增/停用资产趋势、漏洞发现趋势（含严重和高危）、扫描覆盖率、30 天内覆盖率、从未扫描与过期资产数量，以及协议 Top 8 分布。所有统计均受当前用户的资产访问范围约束。
+
+## 资产字段
+
+每条资产可记录：
+
+- Host、IP、域名、端口和协议；
+- 页面标题、服务或产品指纹；
+- 国家/地区、省份/州和城市；
+- 负责人、部门、业务系统、环境和重要性；
+- 来源、来源查询条件和标签；
+- 活跃或停用状态；
+- 所属项目和所有者；
+- 首次发现、最近发现、创建和更新时间；
+- 最近扫描时间及关联的对话、任务队列和子任务；
+- 相关漏洞数量和当前风险等级。
+
+至少需要提供 `host`、`ip` 或 `domain` 中的一项。
+
+## 建立资产基线
+
+### 手工新增
+
+进入 **资产管理 → 资产库**，点击 **新增资产**。常见目标格式包括：
+
+```text
+https://example.com:8443
+example.com
+192.0.2.10:443
+[2001:db8::1]:443
+```
+
+系统会尽量识别 URL、域名、IP、端口和协议。保存前可继续补充项目、标签、标题、服务指纹、地理位置、负责人、部门、业务系统、环境、重要性和状态。
+
+### 从表格批量导入
+
+进入 **资产管理 → 资产库**，点击 **批量导入**：
+
+1. 下载 XLSX（推荐）或 CSV 模板。
+2. 在 `Assets` 工作表中填写资产；不要修改表头。
+3. 上传文件，或将文件拖入上传区域。
+4. 查看逐行校验结果。文件内重复、格式错误和无权访问的项目会标为错误。
+5. 点击 **导入有效数据**。错误行不会提交，预览超过 100 行时只展示前 100 行，但提交会处理全部有效行。
+6. 根据提示核对新增、更新和跳过数量。
+
+模板字段：
+
+| 字段 | 必填 | 说明 |
+| --- | --- | --- |
+| `target` | 条件必填 | URL、域名、IPv4、IPv6 或带端口目标；当 `host`、`ip`、`domain` 均为空时必填 |
+| `project` | 否 | 已有项目的精确名称或项目 ID；留空表示不绑定 |
+| `tags` | 否 | 逗号、中文逗号、分号或竖线分隔；最多 30 个，单个最多 64 个字符 |
+| `host` | 条件必填 | 完整 URL 或 Host；可与 `target` 配合补充 |
+| `ip` | 条件必填 | 合法 IPv4 或 IPv6 |
+| `domain` | 条件必填 | 合法域名，国际化域名会规范化 |
+| `port` | 否 | `0-65535`；留空时可从 `target` 推断 |
+| `protocol` | 否 | 如 `http`、`https`、`ssh`；留空时可从 URL 或常用端口推断 |
+| `title` | 否 | 页面标题，最多 500 个字符 |
+| `server` | 否 | 服务或产品指纹 |
+| `country` / `province` / `city` | 否 | 地理归属信息 |
+| `responsible_person` | 否 | 负责人，最多 255 个字符 |
+| `department` | 否 | 责任部门，最多 255 个字符 |
+| `business_system` | 否 | 所属业务系统，最多 255 个字符 |
+| `environment` | 否 | `production`、`staging`、`testing`、`development` 或 `other` |
+| `criticality` | 否 | `critical`、`high`、`medium` 或 `low` |
+| `status` | 否 | `active` 或 `inactive`，也接受“活跃”“停用”；默认 `active` |
+
+表头同时识别模板中的英文字段和常用中文别名；环境和重要性也接受模板列中对应的中文值。为避免不同系统导出的列名产生歧义，自动化流程仍建议使用模板中的英文表头和枚举值。
+
+限制与处理规则：
+
+- 单个 XLSX/CSV 文件最多 100000 行、100 MB。
+- `/api/assets/import` 单次请求最多 100000 条资产。
+- 文件内相同“目标 + 端口 + 协议”的后续行会标记为重复，不会提交。
+- Web 端负责文件解析、预览和即时格式提示；服务端仍会执行权限检查、字段校验、规范化、去重和事务写入。
+- 已存在的资产会合并本次提供的非空字段并更新最近发现时间；不会创建重复记录。
+- 批量导入需要 `asset:write` 权限。填写项目时，当前用户还必须有权访问该项目。
+- 不建议取消服务端条数上限。更大规模的数据应拆分文件并在低峰期导入。
+
+### 从网络空间测绘搜索导入
+
+1. 在配置文件或 **系统设置 → 资产管理** 中填写对应 API Key，也可使用环境变量：`FOFA_API_KEY`、`ZOOMEYE_API_KEY`、`QUAKE_API_KEY`、`SHODAN_API_KEY`。
+2. 进入 **资产管理 → 信息收集**。
+3. 选择数据源：FOFA、ZoomEye、Quake 或 Shodan。
+4. 输入或生成该数据源的查询语句，并确认查询范围。
+5. 执行查询，选择确认归属的结果后点击 **入库所选**。
+6. 根据返回的新增、更新和跳过数量检查导入结果。
+
+外部搜索结果不等同于自有资产。建议先通过组织域名、证书、网段或产品指纹缩小范围，确认授权后再入库。
+
+## 规范化与去重
+
+不同入口可能使用不同形式描述同一目标。系统会执行以下处理：
+
+- 去除字段首尾空白；
+- IP、域名和协议转为小写；
+- 从 URL 型 Host 提取 hostname、协议和端口；
+- 为未显式指定端口的 HTTP/HTTPS 补充默认端口；
+- 将国际化域名转换为 ASCII/Punycode；
+- 清理并去重标签；
+- 为缺失的状态和来源补充默认值。
+
+资产以“目标 + 端口 + 协议”作为服务级去重依据。目标优先采用域名，其次为 IP，最后为 Host。因此，同一主机的 `80/http` 和 `443/https` 会被视为不同资产。
+
+重复资产再次入库时，系统会更新本次提供的非空字段和最近发现时间，保留未提供的原有信息，不会重置首次发现时间。
+
+## 查询、筛选与视图
+
+Web 端的关键字搜索覆盖 Host、IP、域名、标题、服务、标签、负责人、部门和业务系统。常用筛选包括状态和项目；展开高级筛选后还可以组合：
+
+- 风险等级和最少漏洞数；
+- 协议、端口、来源和精确标签；
+- 已扫描、从未扫描，以及 30/60/90 天未扫描；
+- 国家/地区、省份/州、城市、负责人、部门和业务系统；
+- 环境、重要性、首次发现和最近发现日期范围；
+- 最近发现、最近扫描、风险、漏洞数、首次发现、目标名称或端口排序。
+
+按最近扫描时间升序排列时，从未扫描的资产优先显示，便于识别覆盖盲区。
+
+常用筛选组合可以保存为筛选视图。筛选视图保存在当前浏览器的 `localStorage` 中，不会同步到服务端、其他浏览器或其他用户。
+
+HTTP API 和 `query_assets` 还支持 `max_vulnerabilities`、最近扫描时间范围，以及创建/更新时间等白名单排序字段。HTTP 列表每页最多 100 条，Agent 查询每页最多 50 条。
+
+## 批量维护与导出
+
+选择资产后，可以对当前页执行操作，也可以选择当前筛选条件命中的全部结果。跨页选择由服务端重新解析当前筛选条件，最多返回 10000 条；超过上限时需要进一步缩小范围。
+
+可用操作：
+
+- **绑定项目**：为所选资产统一替换项目归属；
+- **批量编辑**：修改状态、负责人、部门、业务系统、环境和重要性，并增删标签；
+- **创建扫描任务 / 发送到对话**：复用同一提示词模板处理所选资产；
+- **导出 CSV / XLSX**：在浏览器中导出当前已选择的资产，包含责任属性、风险、漏洞数量和时间字段；
+- **合并重复资产**：保留第一个所选资产为主资产，以其他记录的非空字段补齐主资产并合并标签；
+- **批量删除**：永久删除所选资产。
+
+批量编辑、项目绑定和批量删除采用全有或全无的事务：只要其中一个资产不存在或超出调用者权限，整批操作就会失败，不会留下部分更新。
+
+合并仅适用于具有共同域名、IP 或 Host 的记录，每次可选择 2-100 条。主资产已有值优先，标签取并集且仍受 30 个标签限制，其余记录会被删除。该操作同时需要 `asset:write` 和 `asset:delete`；合并前应确认主资产选择以及需要保留的扫描历史。
+
+## 扫描与风险回写
+
+### 单资产扫描
+
+在资产列表中点击 **扫描**。系统会：
+
+1. 创建新对话并注入资产目标和资产 ID；
+2. 将对话与资产关联；
+3. 引导 Agent 检查暴露服务和授权范围内的安全风险；
+4. 使用 `record_vulnerability` 保存确认的问题；
+5. 使用 `complete_asset_scan` 回写扫描状态。
+
+扫描提示词支持 `{{asset_id}}`、`{{target}}`、`{{host}}`、`{{ip}}`、`{{domain}}` 和 `{{port}}` 变量。发起前应按授权范围调整测试强度、端口和验证方式。
+
+### 批量扫描
+
+在资产库中选择多个目标后，点击 **创建扫描任务**。系统会为每个资产创建独立子任务，并建立资产、队列和子任务之间的关联。
+
+当前默认使用手动调度、单并发和 Eino 单 Agent 模式，以减少对目标和本机资源的瞬时压力。执行前仍需确认测试窗口、请求频率、允许的验证方式和审批要求。
+
+### 风险计算
+
+资产风险根据最近一次关联扫描中的未关闭漏洞动态计算：
+
+- `critical`、`high`、`medium`、`low`、`info`：存在对应等级的未关闭漏洞；
+- `normal`：已扫描且没有开放风险；
+- `unassessed`：尚未完成扫描。
+
+已修复、误报或忽略的漏洞仍保留在历史数量中，但不会继续提高当前风险等级。
+
+## Agent 工具
+
+系统向 Agent 提供六个内置资产工具：
+
+- `create_asset`：新增资产或去重更新；
+- `get_asset`：按 ID 获取完整详情；
+- `query_assets`：分页、筛选和排序；
+- `update_asset`：局部更新；
+- `delete_asset`：删除资产；
+- `complete_asset_scan`：扫描完成后回写状态。
+
+`query_assets` 默认每页返回 20 条、最多 50 条摘要。需要完整信息时使用 `get_asset`，避免大量资产数据占用模型上下文。
+
+`create_asset` 和 `update_asset` 均支持责任与业务属性；`query_assets` 也可以按这些字段筛选。Agent 写入仍经过与 HTTP API 相同的规范化、字段校验、去重和权限检查。
+
+## 权限控制
+
+资产权限分为：
+
+- `asset:read`：查看资产和统计数据；
+- `asset:write`：创建、导入、修改和回写扫描；
+- `asset:delete`：删除资产。
+
+服务端会同时检查资产所有者、显式资源授权、所属项目及权限 Scope（`all`、`assigned`、`own`）。当对话绑定项目后，Agent 的资产查询会被限制在该项目内，工具参数不能扩大访问范围。
+
+资产批量接口限制：
+
+- `POST /api/assets/import`：单次最多 100000 条；
+- `GET /api/assets/selection`：最多解析 10000 条匹配资产；
+- `POST /api/assets/scan-links`：单次最多 10000 条；
+- `PUT /api/assets/bulk`：单次最多 10000 个资产 ID；
+- `PUT /api/assets/project-binding`：单次最多 10000 个资产 ID；
+- `POST /api/assets/batch-delete`：单次最多 10000 个资产 ID；
+- `POST /api/assets/merge`：单次合并 2-100 个资产 ID。
+
+## 推荐使用流程
+
+1. 划定一组明确授权的域名、IP 或网段。
+2. 手工加入少量核心目标，验证识别和去重结果。
+3. 使用标签区分生产、测试、核心业务和外网范围。
+4. 配置一个或多个网络空间测绘搜索引擎，从窄查询开始并确认资产归属。
+5. 对单个低风险目标测试扫描和漏洞回写流程。
+6. 使用“从未扫描”和“超过 30 天未扫描”筛选覆盖盲区。
+7. 确认流程稳定后，再逐步创建小规模批量任务。
+
+经过确认的小规模资产基线通常比来源混乱的全量清单更有价值。

+# 工具执行治理
+
+[返回中文文档](README.md)
+
+本文说明 CyberStrikeAI 对长时间工具、MCP 阻塞、大输出、取消和恢复上下文的治理策略。目标是让 Agent 保持标准工具语义，同时避免工具卡死、上下文爆炸、数据库膨胀或恢复时重新注入历史大输出。
+
+## 设计目标
+
+- **Agent 不被工具绑死**：工具调用可以很慢，但当前 runner 只等待有限时间。
+- **长任务可继续观察**：超时返回 `execution_id`，后续可用 `wait_tool_execution` 多轮等待。
+- **用户和 Agent 都能取消**：当前会话结束或用户停止任务时，会取消仍在运行的工具。
+- **数据库与 Agent 视图一致**：DB 保存的是 Agent 实际拿到的兜底后结果，不再保存另一份原始大输出。
+- **恢复不会撑爆上下文**：续跑使用 model-facing trace；历史异常大 tool trace 恢复时也会再次裁剪。
+- **外部 MCP 有隔离保护**：按 server 限并发、按全局限并发，并对连续失败的 server 熔断。
+
+## 执行模型
+
+普通工具调用仍然对 Eino/Agent 表现为一次标准 tool call，但底层执行分为两段：
+
+```text
+Agent 调用工具
+  -> ExecutionService 创建 execution
+  -> worker 执行真实 MCP/工具调用
+  -> Agent bounded wait
+       -> 完成：返回工具结果
+       -> 未完成：返回 execution_id，worker 继续后台运行
+```
+
+这解决了 MCP server、`exec`、`sqlmap`、`nmap`、`nuclei` 等长任务阻塞当前 runner 的问题。
+
+## 工具状态语义
+
+| 状态 | 含义 |
+|---|---|
+| `queued` | execution 已创建，等待 worker 或并发槽位 |
+| `running` | worker 正在执行 |
+| `background_running` | 前端展示状态，表示本轮 Agent 已停止等待，但后台仍在跑 |
+| `completed` | 本次 tool call 本身已完成 |
+| `failed` | 工具真实失败 |
+| `cancelled` | 用户、Agent 或会话清理主动取消 |
+| `hard_timeout` | 超过硬超时，被系统终止 |
+| `orphaned` | 重启/异常后发现 DB 中仍是 running，但运行时已无对应 worker |
+
+注意：`wait_tool_execution` 到达 `timeout_seconds` 时，如果目标 execution 仍在运行，**这次 wait 调用本身是完成的观察动作**，不是工具执行失败。返回体会说明目标仍为 `running`，前端不应显示为红色失败。
+
+## 控制工具
+
+| 工具 | 用途 |
+|---|---|
+| `get_tool_execution` | 读取 execution 当前状态 |
+| `wait_tool_execution` | 等待指定 execution 一段时间 |
+| `cancel_tool_execution` | 主动取消指定 execution |
+
+典型流程：
+
+```text
+1. 调用 exec/sqlmap/nmap 等长任务
+2. 超过 tool_wait_timeout_seconds 后拿到 execution_id
+3. Agent 可继续推理、改用其他工具，或调用 wait_tool_execution
+4. 仍未完成时可继续等待，或调用 cancel_tool_execution
+```
+
+## 取消和会话清理
+
+- 用户点击“停止任务”时，会取消当前会话仍在运行的工具。
+- 会话正常结束后，会批量取消当前会话仍 `running` 的工具。
+- “中断并继续”类流程不会做会话级批量取消，以免误杀后续需要等待的 worker。
+- 取消只针对当前 conversation 绑定的 execution，不会误杀其他会话的工具。
+
+## 外部 MCP 隔离
+
+外部 MCP 可能因为远端 server 卡住、断连或返回异常而拖慢 Agent。系统提供三层保护：
+
+| 能力 | 配置 | 说明 |
+|---|---|---|
+| 单 server 并发限制 | `external_mcp_max_concurrent_per_server` | 同一个外部 MCP server 同时运行的工具数 |
+| 全局并发限制 | `external_mcp_max_concurrent_total` | 所有外部 MCP 工具总并发 |
+| 熔断 | `external_mcp_circuit_failure_threshold` / `external_mcp_circuit_cooldown_seconds` | 单 server 连续失败后短期快速失败，避免反复打坏 server |
+
+推荐默认：
+
+```yaml
+agent:
+  external_mcp_max_concurrent_per_server: 2
+  external_mcp_max_concurrent_total: 16
+  external_mcp_circuit_failure_threshold: 3
+  external_mcp_circuit_cooldown_seconds: 60
+```
+
+## 输出兜底
+
+系统使用 `multi_agent.eino_middleware.reduction_max_length_for_trunc` 作为统一工具结果上限。当前示例配置为 50000 bytes。
+
+```yaml
+multi_agent:
+  eino_middleware:
+    reduction_enable: true
+    reduction_max_length_for_trunc: 50000
+```
+
+兜底覆盖：
+
+| 渠道 | 行为 |
+|---|---|
+| Agent 实际拿到的工具结果 | 使用兜底后的 canonical result |
+| DB/监控存储 | 保存同一份 canonical result |
+| `get_tool_execution` / `wait_tool_execution` | 读取同一份 canonical result |
+| Eino `execute` / filesystem 监控记录 | 完成记录前统一兜底 |
+| 非流式 `exec` stdout/stderr | 源头 bounded buffer |
+| 流式 `exec` stdout/stderr | 推送给前端的累计输出也受上限控制 |
+| PTY 执行路径 | 同样受上限控制 |
+| 前端详情弹窗 | 额外有 UI 展示截断保护 |
+
+触发上限后，完整输出先写入本地 trunc 文件，Agent 侧只保留计入预算的 `<persisted-output>` 预览（含绝对路径）。因此阈值为 50000 时，上下文文本不会超过该上限。
+
+示例：
+
+```text
+<persisted-output>
+Output too large (200000). Full output saved to: /path/to/tmp/reduction/conversations/<id>/trunc/<execution_id>
+Use read_file with offset/limit to read parts of the file.
+Preview (first …):
+…
+
+Preview (last …):
+…
+
+</persisted-output>
+```
+
+当前策略是「全文落盘 + 上下文预览」：超过 `reduction_max_length_for_trunc` 时，完整输出写入本地文件（默认 `tmp/reduction/conversations/<会话ID>/trunc/<execution_id>`），Agent/DB/监控拿到的是带绝对路径的 `<persisted-output>` 预览；可用 `read_file` 按 offset/limit 回读全文。
+
+## DB 与恢复上下文
+
+新执行结果的写入路径如下：
+
+```text
+工具完成
+  -> NormalizeToolResultForStorage
+  -> 写入内存 execution
+  -> 写入 DB
+  -> 返回给 Agent
+```
+
+因此正常情况下，DB 中保存的就是 Agent 拿到的结果。
+
+续跑恢复时，系统使用 `LastAgentTraceInput` 中的 model-facing trace，也就是实际送入 ChatModel 的消息快照，而不是原始事件流累计。恢复入口还会对历史 tool 内容再次应用上限，防止以下情况撑爆上下文：
+
+- 升级前 DB 已经存过原始大输出。
+- 手工迁移或导入的数据绕过了当前写入路径。
+- 配置从更大阈值改成 50000。
+- 未来某条旁路写入漏掉 canonicalize。
+
+## 关键配置建议
+
+长任务场景推荐：
+
+```yaml
+agent:
+  max_iterations: 800
+  tool_timeout_minutes: 60
+  tool_wait_timeout_seconds: 30
+  external_mcp_max_concurrent_per_server: 2
+  external_mcp_max_concurrent_total: 16
+  external_mcp_circuit_failure_threshold: 3
+  external_mcp_circuit_cooldown_seconds: 60
+  shell_no_output_timeout_seconds: 1200
+
+multi_agent:
+  eino_middleware:
+    reduction_enable: true
+    reduction_max_length_for_trunc: 50000
+```
+
+参数说明：
+
+| 参数 | 建议 | 说明 |
+|---|---:|---|
+| `max_iterations` | `300-1000` | 太大等于放弃循环保护 |
+| `tool_timeout_minutes` | `60` | 单次工具硬超时，适合 sqlmap 等长任务 |
+| `tool_wait_timeout_seconds` | `30-60` | Agent 本轮等待上限，到时返回 `execution_id` |
+| `shell_no_output_timeout_seconds` | `600-1200` | 连续无输出时终止，防止静默挂死 |
+| `reduction_max_length_for_trunc` | `50000` | 工具结果统一上限 |
+
+不建议把 `tool_wait_timeout_seconds` 设置得很大。长任务应由 worker 后台跑，Agent 通过 `execution_id` 继续观察，而不是一轮等待数分钟。
+
+## 测试建议
+
+可以用以下对话测试长任务语义：
+
+```text
+调用 exec 执行 sleep 120；如果超过 10 秒还没完成，不要一直等，告诉我 execution_id，然后调用 wait_tool_execution 等 5 秒；如果仍未完成，再调用 cancel_tool_execution，最后说明状态。
+```
+
+可以用以下命令测试大输出兜底：
+
+```text
+调用 exec 执行：python3 - <<'PY'
+print("A" * 200000)
+PY
+然后展示工具结果长度和是否包含截断提示。
+```
+
+预期：
+
+- 初始长任务会返回 `execution_id`，状态为 `running` 或前端展示 `background_running`。
+- `wait_tool_execution` 等待到上限但目标未完成时，本次 wait 调用不应显示为执行失败。
+- 大输出结果不会超过 `reduction_max_length_for_trunc`。
+- DB、监控详情、Agent 继续推理看到的是同一份兜底结果。
+
+## 当前边界
+
+- 外部 MCP 的远端 server 内部如何采集输出不由 CyberStrikeAI 控制；CyberStrikeAI 会在结果进入本系统后统一兜底、限并发和熔断。
+- 超长工具输出会在截断前写入本地 `tmp/reduction/.../trunc/<id>`（或 `reduction_root_dir`），bounded result 中包含可 `read_file` 的绝对路径。
