From f7fe344257c3267216ffb77250340881e362d2e6 Mon Sep 17 00:00:00 2001 From: openhands Date: Fri, 24 Apr 2026 22:18:48 +0000 Subject: [PATCH 01/50] feat: Add KV store API for automation state persistence Implements a built-in key-value store API scoped per-automation for state persistence between runs, as specified in issue #67. Features: - New AutomationKV model with encrypted value storage - enable_kv_store flag on Automation model (opt-in) - Per-run JWT tokens for KV authentication - JWE encryption for all stored values - Full Redis-like API: GET, SET, DELETE, INCR/DECR, LPUSH/RPUSH/LPOP/RPOP - Support for nested paths (dot notation) - Conditional SET operations (nx=true, xx=true) - Database migration for new table Endpoints: - GET /v1/kv - List all keys - GET /v1/kv/{key} - Get value (with optional path and meta params) - PUT /v1/kv/{key} - Set value (with optional nx/xx params) - PATCH /v1/kv/{key} - Update nested path - DELETE /v1/kv/{key} - Delete key - POST /v1/kv/{key}/incr - Atomic increment - POST /v1/kv/{key}/decr - Atomic decrement - POST /v1/kv/{key}/lpush - Push to list front - POST /v1/kv/{key}/rpush - Push to list back - POST /v1/kv/{key}/lpop - Pop from list front - POST /v1/kv/{key}/rpop - Pop from list back - GET /v1/kv/{key}/len - Get list length Related: #67 Co-authored-by: openhands --- automation/app.py | 2 + automation/config.py | 4 + automation/dispatcher.py | 12 + automation/kv_router.py | 946 ++++++++++++++++++++++++ automation/models.py | 47 ++ automation/router.py | 1 + automation/schemas.py | 6 + automation/utils/kv.py | 156 ++++ migrations/versions/005_add_kv_store.py | 69 ++ pyproject.toml | 2 + tests/test_kv_router.py | 624 ++++++++++++++++ uv.lock | 17 + 12 files changed, 1886 insertions(+) create mode 100644 automation/kv_router.py create mode 100644 automation/utils/kv.py create mode 100644 migrations/versions/005_add_kv_store.py create mode 100644 tests/test_kv_router.py diff --git a/automation/app.py b/automation/app.py index ffa5453..d60df32 100644 --- a/automation/app.py +++ b/automation/app.py @@ -17,6 +17,7 @@ from automation.db import create_engine, create_session_factory from automation.dispatcher import dispatcher_loop from automation.event_router import router as event_router +from automation.kv_router import router as kv_router from automation.logger import setup_all_loggers from automation.preset_router import router as preset_router from automation.router import router @@ -174,6 +175,7 @@ def _create_app() -> FastAPI: app.include_router(preset_router, prefix=_base_path) app.include_router(event_router, prefix=_base_path) app.include_router(webhook_router, prefix=_base_path) +app.include_router(kv_router, prefix=_base_path) app.include_router(router, prefix=_base_path) diff --git a/automation/config.py b/automation/config.py index e0e1dbe..50d4621 100644 --- a/automation/config.py +++ b/automation/config.py @@ -316,6 +316,10 @@ class ServiceSettings(BaseSettings): # Used by the OpenHands server when forwarding GitHub events webhook_secret: str = "" + # Secret key for signing KV store JWT tokens and encrypting KV values. + # Must be set to enable the KV store feature. + kv_secret: str = "" + model_config = {"env_prefix": "AUTOMATION_"} @property diff --git a/automation/dispatcher.py b/automation/dispatcher.py index 6152908..06751d8 100644 --- a/automation/dispatcher.py +++ b/automation/dispatcher.py @@ -26,6 +26,7 @@ from automation.models import AutomationRun, AutomationRunStatus, TarballUpload from automation.utils import log_extra from automation.utils.api_key import APIKeyError, get_api_key_for_automation_run +from automation.utils.kv import create_kv_token from automation.utils.run import ( disable_automation, mark_run_status, @@ -164,6 +165,17 @@ def _log_ctx(sandbox_id: str | None = None) -> dict[str, Any]: env_vars["AUTOMATION_EVENT_PAYLOAD"] = json.dumps(trigger_context) + # Generate KV token if automation has KV store enabled + if automation.enable_kv_store and settings.kv_secret: + kv_token = create_kv_token( + secret=settings.kv_secret, + automation_id=automation.id, + run_id=run.id, + ) + env_vars["AUTOMATION_KV_TOKEN"] = kv_token + env_vars["AUTOMATION_ENABLE_KV_STORE"] = "true" + logger.debug("KV store enabled for run", extra=log_extra()) + # 4.

Some kinds of integrations—like many webhook responders—will have a stateless implementation. They receive an event, do some work, and complete. No memory of previous runs is needed. + +But other kinds of jobs require small amounts of data storage to work effectively. + +For example, consider an automation that summarizes data from Slack or another source. A common pattern would be for each run of the integration to store the last timestamp of the retrieved dataset, and then on the next scheduled run, look for items since that date. This avoids reprocessing the entire history on every run and enables efficient incremental sync patterns. + +**But where should the automation store this data?** + +Surely a GitHub repo wouldn't be a great fit—commits for every timestamp update would pollute the history and is simply the wrong tool for the job. + +We could have integration authors use custom solutions for persistence—JSONBin.io, Redis Cloud, a personal database, or some other external service. These work, but they require users to provision, configure, and manage external infrastructure. + +If external systems are required for such a prevalent use case, that erodes the simplicity of having a **batteries-included** solution. The promise of the automation platform is that you can build and deploy integrations without managing infrastructure. Requiring external storage for basic state persistence breaks that promise. + +## Solution + +Provide a built-in **key-value store API** scoped to each automation.

Instead, atomic operations use row-level locking: + +```python +async def incr(self, automation_id: UUID, key: str, by: int = 1) -> int: + async with session.begin(): + # 1. Lock the row + row = await session.execute( + select(AutomationKV) + .where(AutomationKV.automation_id == automation_id) + .where(AutomationKV.key == key) + .with_for_update() # Row-level lock + ) + kv = row.scalar_one_or_none() + + # 2. Decrypt, modify, encrypt + if kv is None: + value = by # Initialize if not exists + kv = AutomationKV(automation_id=automation_id, key=key) + session.add(kv) + else: + value = decrypt_value(kv.value_encrypted) + if not isinstance(value, (int, float)): + raise TypeError("Cannot increment non-numeric value") + value += by + + # 3. Update with encrypted value + kv.value_encrypted = encrypt_value(value) + + # 4. Commit releases lock + return value +``` + +**Concurrency model:** +- Each key is a row → row-level locking per key +- Two operations on different keys → no contention +- Two operations on same key → serialized (one waits) +- Different automations → completely isolated + +This is acceptable for our use case (automations doing 5-10 KV ops per run).

---- - -## ⚠️ CRITICAL BUG FOUND - -**Issue:** The `AUTOMATION_KV_TOKEN` environment variable is **NOT being injected** into the sandbox even when `enable_kv_store: true` is set on the automation. - -**Evidence from testing:** -- Created automation with `enable_kv_store: true` -- Dispatched run, confirmed status = COMPLETED -- Checked conversation events via `/api/v1/conversation/{id}/events` -- Agent output showed: `"Checking if token exists: 0 chars"` (token is empty) -- All KV API calls failed with `"Invalid authorization header format"` or `"Invalid token: Not enough segments"` - -**Root Cause:** The dispatcher is not generating/injecting the KV token into the sandbox environment. - -**Blocking:** All KV operation tests (Categories 3-11) are blocked until this is fixed. - ---- - -## Overview - -This test plan covers the KV Store API feature that enables automations to persist state between runs. The feature includes: -- Enable/disable KV store per automation (`enable_kv_store` flag) -- JWT-based authentication scoped per automation -- Full CRUD operations on keys -- Atomic increment/decrement operations -- List operations (LPUSH, RPUSH, LPOP, RPOP, LEN) -- Nested path access and updates -- Application-level encryption for stored values - ---- - -## Prerequisites - -```bash -export BASE_URL="https://au-pr-69.staging.all-hands.dev" -export API_KEY="sk-oh-4qEHoRWN7KtS5hXwF9W3UhobmLxmXfKy" -``` - ---- - -## How to View Automation Run Results - -Automation runs create conversations. Use this 3-step process to view what the agent did: - -### Step 1: Find the Conversation ID - -List conversations and find your automation run by name: - -```bash -curl -s "${BASE_URL}/api/v1/app-conversations/search?limit=10" \ - -H "Authorization: Bearer ${API_KEY}" \ - | jq '.items[] | { - conversation_id: .id, - sandbox_id, - automation_name: .tags.automationname, - automation_run_id: .tags.automationrunid, - status: .sandbox_status - }' -``` - -**Example output:** -```json -{ - "conversation_id": "4ec5184247bd4be1a73c6201e602fa71", - "sandbox_id": "3DiQDstrENTVx3XaHAksKh", - "automation_name": "KV Test - Basic Operations", - "automation_run_id": "535745b5-fe0d-42e7-b051-0bc35b222a80", - "status": "MISSING" -} -``` - -### Step 2: List Event IDs - -Get the event IDs for that conversation (note: this endpoint returns metadata only, not payloads): - -```bash -CONV_ID="4ec5184247bd4be1a73c6201e602fa71" - -curl -s "${BASE_URL}/api/v1/conversation/${CONV_ID}/events/search?limit=50" \ - -H "Authorization: Bearer ${API_KEY}" \ - | jq '.items[] | {id, kind, timestamp}' -``` - -**Example output:** -```json -{"id": "1564b4de-0069-40ad-9ee2-0dece6a8016c", "kind": "ActionEvent", "timestamp": "2026-04-25T01:41:11"} -{"id": "576ab2b1-5325-44df-9db2-6874bf4c4d40", "kind": "ObservationEvent", "timestamp": "2026-04-25T01:41:12"} -``` - -### Step 3: Fetch Full Events with Payloads - -Use the batch endpoint to get complete event details including command outputs: - -```bash -CONV_ID="4ec5184247bd4be1a73c6201e602fa71" - -# Build the query string from event IDs -EVENT_IDS=$(curl -s "${BASE_URL}/api/v1/conversation/${CONV_ID}/events/search?limit=50" \ - -H "Authorization: Bearer ${API_KEY}" \ - | jq -r '.items | map("id=" + .id) | join("&")') - -# Fetch full events and filter to ObservationEvents (command outputs) -curl -s "${BASE_URL}/api/v1/conversation/${CONV_ID}/events?${EVENT_IDS}" \ - -H "Authorization: Bearer ${API_KEY}" \ - | jq '.[] | select(.kind == "ObservationEvent") | { - command: .observation.command, - output: .observation.content[0].text[0:300] - }' -``` - -**Example output:** -```json -{ - "command": "echo \"${AUTOMATION_KV_TOKEN:0:20}\"", - "output": "" -} -{ - "command": "env | grep -i -E \"^(AUTOMATION|KV|TOKEN|KEY)\" || echo \"No matching env vars found\"", - "output": "No matching env vars found" -} -``` - -### One-Liner (Combined Steps 2 & 3) - -```bash -CONV_ID="" && \ -EVENT_IDS=$(curl -s "${BASE_URL}/api/v1/conversation/${CONV_ID}/events/search?limit=50" \ - -H "Authorization: Bearer ${API_KEY}" | jq -r '.items | map("id=" + .id) | join("&")') && \ -curl -s "${BASE_URL}/api/v1/conversation/${CONV_ID}/events?${EVENT_IDS}" \ - -H "Authorization: Bearer ${API_KEY}" \ - | jq '.[] | select(.kind == "ObservationEvent") | {command: .observation.command, output: .observation.content[0].text[0:200]}' -``` - -### Helper: Parse Test Results from Events - -Once KV token injection is fixed, use this to extract test results: - -```bash -# Find the test output in events -curl -s "${BASE_URL}/api/v1/conversation/${CONV_ID}/events?${EVENT_IDS}" \ - -H "Authorization: Bearer ${API_KEY}" \ - | jq -r '.[] | select(.kind == "ObservationEvent") | .observation.content[0].text' \ - | grep -A 100 "TEST RESULTS START" | grep -B 100 "TEST RESULTS END" -``` - ---- - -## Testing Strategy - -### Challenge -- KV API requires `AUTOMATION_KV_TOKEN` which is only available inside the sandbox -- Automation runs use an OpenHands agent which is non-deterministic -- Cannot run tests directly via curl from outside - -### Recommended Approach - -**Phase 1: External Tests (Categories 1-2)** -- Test automation CRUD and auth rejection directly via curl -- These don't require the KV token - -**Phase 2: Agent-Based Tests (Categories 3-11)** -Once token injection is fixed: - -1. Create automation with a prompt containing explicit test commands -2. Dispatch the run -3. Wait for completion -4. Fetch conversation events -5. Parse ObservationEvents for test output -6. Look for markers like `=== TEST RESULTS START ===` to find results - -**Example Test Prompt:** -``` -Run these exact commands and print all output: - -echo "=== TEST RESULTS START ===" -echo "TC-3.1:" && curl -s -X PUT "$BASE/api/automation/v1/kv/test" -H "Authorization: Bearer $AUTOMATION_KV_TOKEN" -H "Content-Type: application/json" -d '"value"' -echo "TC-3.3:" && curl -s "$BASE/api/automation/v1/kv/test" -H "Authorization: Bearer $AUTOMATION_KV_TOKEN" -echo "=== TEST RESULTS END ===" -``` - -**Limitation:** Agent may not execute commands exactly as written.

-## Initial Validation Results - -The following tests were executed during test plan creation to validate the API is functional: - -### TC-1.1: Create automation with prompt preset ✅ -**Response:** -```json -{ -

-### TC-1.4: Update automation to enable KV store ✅ -**Response:** -```json -{ - "id": "efad83bf-b717-4512-b117-f5ebea9d9d44", - "enable_kv_store": true, - "updated_at": "2026-04-25T01:35:28.416446Z" -} -``` -**Finding:** PATCH endpoint correctly updates the `enable_kv_store` flag. +# Enable KV, dispatch, note automation_id as A_ID -### TC-2.1: Access KV API without token ✅ -**Response:** -```json -{ - "detail": [{"type": "missing", "loc": ["header", "authorization"], "msg": "Field required"}] -} -``` -**Finding:** API correctly rejects requests without authorization header (HTTP 422). - -### TC-2.2: Access KV API with invalid token ✅ -**Response:** -```json -{"detail": "Invalid token: Not enough segments"} -``` -**Finding:** API correctly rejects malformed tokens. - -### TC-2.3: Access KV API with API key (not KV token) ✅ -**Response:** -```json -{"detail": "Invalid token: Not enough segments"} -``` -**Finding:** API correctly rejects regular API keys - KV store requires specific JWT tokens generated during automation runs. - -### Dispatch and Run ✅ -Successfully dispatched a run which transitioned from `PENDING` to `RUNNING` status. - ---- - -## Verification Strategy - -Since the KV API requires a special JWT token (`AUTOMATION_KV_TOKEN`) that's **only available inside the automation sandbox**, direct curl testing of KV operations is not possible from outside. Instead, use these verification approaches: - -### Approach 1: Prompt-Based Testing (Recommended) - -Create automations with prompts that instruct the agent to perform KV operations and report results. The agent has access to the KV token via environment variable. - -**Example Test Automation Prompts:** - -```bash -# TC-3.1 through TC-3.10: Basic CRUD Operations +# Create Automation B - writes "shared-name" = "I am B" curl -X POST "${BASE_URL}/api/automation/v1/preset/prompt" \ -H "Authorization: Bearer ${API_KEY}" \ -H "Content-Type: application/json" \ -d '{ - "name": "KV Basic CRUD Test", - "prompt": "Test the KV store API by performing these operations and reporting all results:\n\n1.

Reject NaN, Infinity, -Infinity (not valid JSON, causes issues with JavaScript JSON.parse and other strict parsers) - Maximum nesting depth of 32 levels (prevents stack overflow DoS) - Only JSON-serializable types accepted Implementation: - automation/utils/kv.py: Add _validate_json_value() with allow_nan=False, _check_nesting_depth() for DoS prevention, new KVValueError exception - automation/kv_helpers.py: Add safe_encrypt() helper that converts KVValueError to HTTP 400, KVEncryptionError to HTTP 500 - automation/kv_router.py: Replace all encrypt_value try/except blocks with safe_encrypt() for cleaner code and consistent error handling Error responses: - 400 Bad Request for invalid values (client's fault) - 500 Internal Server Error for encryption failures (our fault) Tests added for: - NaN, Infinity, -Infinity rejection - Deep nesting rejection (35 levels) - Valid nesting acceptance (10 levels) - All standard JSON types acceptance Co-authored-by: openhands --- automation/kv_helpers.py | 59 ++++++++++++++++++++- automation/kv_router.py | 111 +++++---------------------------------- automation/utils/kv.py | 93 ++++++++++++++++++++++++++++++-- tests/test_kv_router.py | 91 ++++++++++++++++++++++++++++++++ 4 files changed, 249 insertions(+), 105 deletions(-) diff --git a/automation/kv_helpers.py b/automation/kv_helpers.py index 726d480..a747a45 100644 --- a/automation/kv_helpers.py +++ b/automation/kv_helpers.py @@ -1,10 +1,24 @@ -"""Helper functions for KV store path operations. +"""Helper functions for KV store operations. -Provides utilities for parsing and manipulating nested paths in JSON values. +Provides utilities for: +- Parsing and manipulating nested paths in JSON values +- Safe encryption with proper HTTP error handling """ +import logging from typing import Any +from fastapi import HTTPException, status + +from automation.utils.kv import ( + KVEncryptionError, + KVValueError, + encrypt_value, +) + + +logger = logging.getLogger(__name__) + def parse_path(path: str) -> list[str]: """Parse a path string into parts. @@ -128,3 +142,44 @@ def set_nested_value(obj: dict, path: str, value: Any) -> dict: current[parts[-1]] = value return obj + + +def safe_encrypt(secret: str, value: Any) -> bytes: + """Encrypt a value with proper HTTP error handling. + + Wraps encrypt_value() to convert exceptions to appropriate HTTP errors: + -

Reject empty and whitespace-only keys - Enforce max key length (255 chars, matching DB constraint) - Reject control characters (null bytes, newlines, tabs, etc.) - Provide helpful error messages with character position Type Validation Improvements: - require_numeric: Now rejects booleans (True/False) explicitly - Prevents confusing behavior where True becomes 2 after increment - require_int: New function for incr/decr operations - Rejects floats to prevent silent precision loss - Rejects booleans for same reason as require_numeric Path Validation: - Added _MAX_PATH_DEPTH (32) limit to parse_path() - Prevents DoS via extremely long dot-notation paths Router Changes: - Added ValidatedKey type alias using Depends for consistent key validation - All endpoints now validate key parameter automatically - incr/decr now use require_int instead of require_numeric - Fixed incr/decr to use integer arithmetic (was doing int(value + by)) Tests: - Added 54+ new tests for key validation edge cases - Added tests for boolean rejection in require_numeric/require_int - Added tests for float rejection in require_int - Added tests for path depth limiting - Added API-level tests for incr/decr integer-only behavior Co-authored-by: openhands --- automation/kv_helpers.py | 118 ++++++++++- automation/kv_router.py | 53 +++-- tests/test_kv_helpers.py | 433 ++++++++++++++++++++++++++++++++++++++- tests/test_kv_router.py | 148 +++++++++++++ 4 files changed, 727 insertions(+), 25 deletions(-) diff --git a/automation/kv_helpers.py b/automation/kv_helpers.py index ad91768..ac5c48d 100644 --- a/automation/kv_helpers.py +++ b/automation/kv_helpers.py @@ -4,6 +4,7 @@ -

This created deadlock risk when: - Concurrent requests modified different keys for the same automation - Client code acquired locks on multiple keys in different orders - The FOR UPDATE locking strategy serialized on N separate rows ## Solution: Single-Document Design Changed to store all KV state in ONE encrypted JSON document per automation. API 'keys' (e.g., /kv/config, /kv/counter) are now top-level fields within this single document. Benefits: - Only ONE row per automation to lock - All operations serialize through that single lock - No multi-key ordering issues possible - Eliminates deadlock risk between keys Trade-off: Every operation reads/writes the entire state blob. This is acceptable because automation state is intended to be small (cursors, counters, configs) and access is infrequent (scheduled runs).

Lock Timeout (kv_router.py): - Add SET LOCAL lock_timeout = '5000ms' before FOR UPDATE queries - Prevents indefinite waits when another transaction holds the row lock - If lock times out, return HTTP 409 Conflict so clients can retry - SET LOCAL scopes timeout to current transaction only 2. Pool Exhaustion Protection (db.py, config.py): - Add db_pool_timeout config setting (default 30s) - Apply pool_timeout to both standard and GCP Cloud SQL engines - Surfaces pool exhaustion as errors instead of indefinite hangs Why these protections matter: Without lock timeout, a slow/stuck transaction (e.g., network issue during commit, slow crypto) causes all concurrent KV operations on that automation to queue indefinitely. With enough concurrent requests, this exhausts the connection pool and degrades the entire service—not just one automation. The single-document design already eliminates multi-row deadlock scenarios. These timeouts provide defense-in-depth against operational issues.

DELETE) - Add if_version query param to PUT /v1/kv/{key} for optimistic concurrency - Add if_version query param to PATCH /v1/kv/{key} for optimistic concurrency - Add if_version query param to DELETE /v1/kv/{key} for optimistic concurrency - Add integration tests for if_version on individual endpoints - Fix pyright type errors in tests The atomic operations (incr, decr, lpush, rpush, lpop, rpop)

`push`, `pop`) when possible - they're conflict-free +- **Keep state small** (< 64KB total, ideally < 8KB for best performance) +- **Design for idempotency** - operations may be retried +- **Use batch endpoint** for multiple updates in one operation +- **Implement proper retry logic** for concurrent event handlers +- **Set appropriate `kv_lock_timeout_ms`** based on your use case + +### DON'T ❌ + +- **Read state, sleep, then write** - maximizes contention +- **Store large blobs** - use object storage instead +- **Ignore 409 errors** - always handle with retry +- **Use KV as a queue** - use proper message queues for high-throughput +- **Rely on ordering** across concurrent writes + +### Lock Timeout Configuration + +Configure `kv_lock_timeout_ms` based on your automation type: + +| Use Case | Recommended Timeout | Rationale | +|----------|---------------------|-----------| +| High-throughput event handlers | 2000ms | Fail fast, retry quickly | +| Standard scheduled jobs | 5000ms (default) | Balanced wait/fail | +| Long-running batch jobs | 10000ms | Allow more contention | +| Critical single-run ops | 500-1000ms | Immediate feedback | + +Set via automation config: +```json +{ + "name": "my-automation", + "enable_kv_store": true, + "kv_lock_timeout_ms": 2000, + ... +} +``` + +## Error Handling + +| Status | Meaning | Action | +|--------|---------|--------| +| 200 | Success (update) | - | +| 201 | Success (create) | - | +| 400 | Bad request | Fix request (invalid key, etc.) | +| 401 | Unauthorized | Check token | +| 404 | Key not found | Handle missing key | +| 409 | Conflict | Retry with backoff (see `Retry-After` header) | +| 413 | Payload too large | Reduce state size | +| 503 | Service unavailable | KV store not configured | + +### 409 Conflict Types + +The 409 response can indicate: + +1. **Lock timeout** (`kv_store_busy`): Another operation is holding the lock + ```json + {"detail": "kv_store_busy: another operation is in progress, please retry"} + ``` + +2. **Version mismatch** (`version_mismatch`): State changed since your read + ```json + { + "detail": { + "error": "version_mismatch", + "expected_version": 5, + "actual_version": 6 + } + } + ``` +

Following the centralized configuration pattern from PR #73, this moves KV store settings from ServiceSettings to a dedicated KVSettings section: - Add KVSettings class with kv_secret, kv_max_value_size, enabled property - Add config.kv property to AppConfig - Update kv_router.py to use get_config().kv for all KV settings - Update dispatcher.py to use get_config().kv for KV token generation - Update AGENTS.md with KV config section in documentation This keeps feature-specific configuration organized and follows the existing pattern of http, sandbox, storage, and log sections.

Padding with null bytes if shorter than 32 bytes - -This is simple but adequate for our use case where: -- The secret is configured by operators (not user-supplied) -- Key rotation requires re-encryption of all values anyway - -For a more robust approach, consider HKDF or Argon2 key derivation. -This is noted as a potential future improvement. - - -Wire Format -=========== - -Encrypted values are stored as: nonce || ciphertext || tag - - +------------+------------------+------------+ - | 12 bytes | variable length | 16 bytes | - | nonce/IV | ciphertext | auth tag | - +------------+------------------+------------+ - -- Nonce: Random 96-bit IV, generated fresh for each encryption -- Ciphertext: AES-256-GCM encrypted JSON bytes -- Auth tag: 128-bit authentication tag (integrity protection) - -Total overhead: 28 bytes (fixed, regardless of plaintext size) +- Strict-JSON validation (rejects NaN/Infinity, caps nesting depth) +- Encryption/decryption of KV state via the SDK's :class:`Cipher` + +The :class:`Cipher` helper from ``openhands.sdk.utils.cipher`` wraps Fernet +(AES-128-CBC + HMAC-SHA256).
