#19818: docs: add IC Sovereign Persistent Memory to community plugins

## Summary - Adds **IC Sovereign Persistent Memory** as the first entry on the [community plugins](https://docs.openclaw.ai/plugins/community) page. ## Plugin details | Field | Value | |---|---| | npm | [`openclaw-ic-sovereign-persistent-memory`](https://www.npmjs.com/package/openclaw-ic-sovereign-persistent-memory) | | Version | 1.1.0 | | Repo | [TheAmSpeed/openclaw-ic-sovereign-persistent-memory](https://github.com/TheAmSpeed/openclaw-ic-sovereign-persistent-memory) | | Install | `openclaw plugins install openclaw-ic-sovereign-persistent-memory` | | Kind | `memory` (exclusive slot) | | License | MIT | ## What it does Stores AI memories in personal Internet Computer canisters that only the user controls. Solves the three common OpenClaw memory failure modes (memory never saved, saved but never retrieved, compaction destroys knowledge). **v1.1.0 features:** - **Smart Memory Recall** — `before_agent_start` hook searches the IC vault for relevant memories and injects them as `prependContext` before every conversation - **Auto-Capture** — `agent_end` hook reads local memory files (`MEMORY.md`, `memory/*.md`) and extracts from conversation messages, syncs to IC vault automatically - **Compaction Protection** — `before_compaction` hook saves memories to IC vault before compaction can destroy them - **Owner-only access** — every query and mutation checks `caller == owner` - **Ed25519 identity** stored in OS keychain (macOS Keychain / Linux Secret Service), AES-256-GCM encrypted file fallback - **Differential sync** via SyncManifest checksums - **Immutable audit log** with consensus-verified timestamps - **Cross-device restore** via `export-identity` / `import-identity` (stdin, not CLI args) - **9 CLI commands** including `revoke` (full sovereignty) and `delete-identity` - **5 agent tools**: `vault_sync`, `vault_recall`, `vault_restore`, `vault_status`, `vault_audit` ## Quality signals - **130 unit tests** (Vitest) — config, encoding, sync, prompting, identity, encryption, memory reader, search terms - **13 E2E tests passing on IC mainnet** — vault creation, store, recall, stats, dashboard, categories, recallRelevant, sync manifest, audit log, sessions, delete, verify deletion - **Real-world tested** — full agent conversations with smart recall verified on OpenClaw 2026.2.18 + Gemini 3 Pro - **5 security audit rounds** (64+ issues found and fixed) - Factory canister deployed and live: `v7tpn-laaaa-aaaac-bcmdq-cai` ## Prior PRs This was previously submitted as PRs #18853 and #18877 (both to the main repo). Per @steipete's feedback, it was moved to a standalone community plugin repo. This PR only adds a one-line entry to the community plugins docs page. ## Change Only `docs/plugins/community.md` — adds a `## Plugins` section with one entry.
