fix: restore verified unified kernel baseline

- fix securebus execute-once, redaction-safe persistence, and failure terminalization across main and subagent runs
- harden session continuity, heartbeat isolation, and context-carried tool execution metadata without regressing eval workflows
- restore full verification baseline with prompt/eval/tooling fixes and sync docs to shipped branch truth

-| **Isolated Tool Runtime** | All tool calls route through a `SecureBus` that enforces capability manifests, injects secrets, scans output for leaks, and writes audit logs. The LLM never sees raw secrets. Layer 1-2 are live today; daemon/WASM isolation remains optional roadmap work. See [ADR-001](docs/adr/001-isolated-tool-runtime.md). |
+| **Isolated Tool Runtime** | All tool calls route through a `SecureBus` that mediates execution, applies recursion-depth policy, performs `arg:` secret injection, scans LLM-facing output for leaks, and writes audit logs. Broader network/filesystem capability enforcement plus daemon/WASM isolation remain follow-on work. See [ADR-001](docs/adr/001-isolated-tool-runtime.md). |
 | **DAG executor** | LLMCompiler-style parallel tool dispatch. The planner builds a dependency DAG in a single inference pass; the executor dispatches independent nodes concurrently. Joiner synthesizes results. Replanning on failure. Falls back to ReAct for simple single-tool cases. |
 | **Vendored Fantasy SDK** | `charm.land/fantasy` vendored into `internal/fantasy/` via `go.mod` replace directive. Enables direct modification for streaming hooks, tool call repair, and progressive disclosure. |
 | **MemGPT + Projection Kernel** | Working context (hot), recall items (warm), archival chunks (cold, embedded + indexed), observational memory, immutable messages, DAG snapshots, runtime checkpoints, and an active-context projection builder that assembles the live turn context. Semantic ContextTree scoring and RLM reduction now participate in the hot path. |
-| **Progressive tool disclosure** | Agent sees only `tool_search` and `tool_call` meta-tools. Discovers actual tools on demand via fuzzy search. Cuts system prompt tokens for large registries. |
+| **Progressive tool disclosure** | Gateway tools stay visible, and the agent gets a small query-aware direct toolset for the current request. Wider discovery still flows through `tool_search` / `tool_call` and dynamic promotion, which keeps prompt size down without hiding obvious direct actions. |
 | **libSQL over modernc/sqlite** | Native F32_BLOB for vector storage, `libsql_vector_idx` for ANN search, FTS5 for full-text. Single database, no external vector DB dependency. |
 | **BLOB primary keys** | 16-byte UUIDv7 stored as BLOB. Compact, byte-comparable, monotonically sortable by creation time. |
-| **XChaCha20-Poly1305 vault** | Secrets encrypted at rest with AES-256-GCM or XChaCha20-Poly1305. Master key from OS keyring, env var, or file. Schnorr ZKP remains planned for daemon-mode authentication. |
+| **XChaCha20-Poly1305 vault** | Secrets are encrypted at rest with XChaCha20-Poly1305. The current user-facing master-key flow is env-backed via `DRAGONSCALE_MASTER_KEY`; richer keyring/file-backed flows remain roadmap work. |
 | **Goose migrations** | Schema managed by `pressly/goose/v3`. 17 versioned migrations currently cover core schema, FTS5, vector indexes, KV store, documents, audit log outcomes, conversations, runtime state, DAG/checkpoint data, map operators, memory edges, soft delete, immutable messages, and RL/task-completion tables. |
-| **FlatBuffers command protocol** | Zero-copy serialized `ToolRequest`/`ToolResponse` for the ITR command vocabulary. Same binary format across in-process channels, Unix sockets (daemon mode), and wazero WASM host calls. |
+| **FlatBuffers command protocol** | Zero-copy serialized `ToolRequest`/`ToolResponse` for the ITR command vocabulary. The binary format is live on the in-process command path today and is designed to extend to socket/WASM transports as those optional surfaces mature. |

 A compromised tool — via prompt injection, malicious skill, or supply chain attack — has the same memory-space access as the agent itself. This is the same class of vulnerability that led to the OpenClaw token exfiltration incident (Feb 2026), where malicious skills on ClawHub could read API keys from the host environment and exfiltrate them through tool output.
