* fix: prune stale session entries, cap entry count, and rotate sessions.json
The sessions.json file grows unbounded over time. Every heartbeat tick (default: 30m)
triggers multiple full rewrites, and session keys from groups, threads, and DMs
accumulate indefinitely with large embedded objects (skillsSnapshot,
systemPromptReport). At >50MB the synchronous JSON parse blocks the event loop,
causing Telegram webhook timeouts and effectively taking the bot down.
Three mitigations, all running inside saveSessionStoreUnlocked() on every write:
1. Prune stale entries: remove entries with updatedAt older than 30 days
(configurable via session.maintenance.pruneDays in openclaw.json)
2. Cap entry count: keep only the 500 most recently updated entries
(configurable via session.maintenance.maxEntries). Entries without updatedAt
are evicted first.
3. File rotation: if the existing sessions.json exceeds 10MB before a write,
rename it to sessions.json.bak.{timestamp} and keep only the 3 most recent
backups (configurable via session.maintenance.rotateBytes).
All three thresholds are configurable under session.maintenance in openclaw.json
with Zod validation. No env vars.
Existing tests updated to use Date.now() instead of epoch-relative timestamps
(1, 2, 3) that would be incorrectly pruned as stale.
27 new tests covering pruning, capping, rotation, and integration scenarios.
* feat: auto-prune expired cron run sessions (#12289)
Add TTL-based reaper for isolated cron run sessions that accumulate
indefinitely in sessions.json.
New config option:
cron.sessionRetention: string | false (default: '24h')
The reaper runs piggy-backed on the cron timer tick, self-throttled
to sweep at most every 5 minutes. It removes session entries matching
the pattern cron:<jobId>:run:<uuid> whose updatedAt + retention < now.
Design follows the Kubernetes ttlSecondsAfterFinished pattern:
- Sessions are persisted normally (observability/debugging)
- A periodic reaper prunes expired entries
- Configurable retention with sensible default
- Set to false to disable pruning entirely
Files changed:
- src/config/types.cron.ts: Add sessionRetention to CronConfig
- src/config/zod-schema.ts: Add Zod validation for sessionRetention
- src/cron/session-reaper.ts: New reaper module (sweepCronRunSessions)
- src/cron/session-reaper.test.ts: 12 tests covering all paths
- src/cron/service/state.ts: Add cronConfig/sessionStorePath to deps
- src/cron/service/timer.ts: Wire reaper into onTimer tick
- src/gateway/server-cron.ts: Pass config and session store path to deps
Closes#12289

* security: add mDNS discovery config to reduce information disclosure
mDNS broadcasts can expose sensitive operational details like filesystem
paths (cliPath) and SSH availability (sshPort) to anyone on the local
network. This information aids reconnaissance and should be minimized
for gateways exposed beyond trusted networks.
Changes:
- Add discovery.mdns.enabled config option to disable mDNS entirely
- Add discovery.mdns.minimal option to omit cliPath/sshPort from TXT records
- Update security docs with operational security guidance
Minimal mode still broadcasts enough for device discovery (role, gatewayPort,
transport) while omitting details that help map the host environment.
Apps that need CLI path can fetch it via the authenticated WebSocket.
* fix: default mDNS discovery mode to minimal (#1882) (thanks @orlyjamie)

* feat(discord): add exec approval forwarding to DMs
Add support for forwarding exec approval requests to Discord DMs,
allowing users to approve/deny command execution via interactive buttons.
Features:
- New DiscordExecApprovalHandler that connects to gateway and listens
for exec.approval.requested/resolved events
- Sends DMs with embeds showing command details and 3 buttons:
Allow once, Always allow, Deny
- Configurable via channels.discord.execApprovals with:
- enabled: boolean
- approvers: Discord user IDs to notify
- agentFilter: only forward for specific agents
- sessionFilter: only forward for matching session patterns
- Updates message embed when approval is resolved or expires
Also fixes exec completion routing: when async exec completes after
approval, the heartbeat now uses a specialized prompt to ensure the
model relays the result to the user instead of responding HEARTBEAT_OK.

Adds the ability to customize the assistant's name and avatar in the Web UI.
Configuration options:
- config.ui.assistant.name: Custom name (replaces 'Assistant')
- config.ui.assistant.avatar: Emoji or letter for avatar (replaces 'A')
Also reads from workspace IDENTITY.md as fallback:
- Name: field sets the assistant name
- Emoji: field sets the avatar
Priority: config > IDENTITY.md > defaults
Closes#1383
