- Every actor execution input now includes a pre-resolved `executionContext` (`phase`, `modelConstraint`, `allowedTools`, and immutable security constraints) generated by orchestration per node attempt.
- Every actor execution input now includes `security` helpers (`rulesEngine`, `createCommandExecutor(...)`) so executors can enforce shell/tool policy at the execution boundary.
- Every actor execution input now includes `mcp` helpers (`registry`, `resolveConfig(...)`) so MCP server config resolution stays centrally policy-controlled per persona/tool-clearance.
- For Claude-based executors, use `input.mcp.createClaudeCanUseTool()` as the SDK `canUseTool` callback to enforce persona allowlist/banlist before each tool invocation.
- Every actor execution input now includes `mcp` helpers (`resolvedConfig`, `resolveConfig(...)`, `filterToolsForProvider(...)`, `createClaudeCanUseTool()`) so provider adapters are filtered against `executionContext.allowedTools` before SDK calls.
- For Claude-based executors, pass `input.mcp.filterToolsForProvider(...)` and `input.mcp.createClaudeCanUseTool()` into the SDK call path so unauthorized tools are never exposed and runtime bypass attempts trigger security violations.
- Pipeline behavior on `SecurityViolationError` is configurable:
- `hard_abort` (default)
- `validation_fail` (retry-unrolled remediation)

Node payloads are persisted under the state root. Nodes do not inherit in-memory conversational context from previous node runs. Fresh context is reconstructed from the handoff and persisted state each execution. Sessions load project context from `AGENT_PROJECT_CONTEXT_PATH` at initialization, and orchestration writes project updates on each node completion.
## Resolved execution contract
Before each actor invocation, orchestration resolves an immutable `ResolvedExecutionContext` and injects it into the executor input:
- `phase`: current pipeline node id
- `modelConstraint`: persona-level model policy (or runtime fallback)
- `allowedTools`: flat resolved tool list for that node attempt
- `security`: hard runtime constraints (`dropUid`, `dropGid`, `worktreePath`, violation handling mode)
This keeps orchestration policy resolution separate from executor enforcement. Executors do not need to parse manifests or MCP registry internals.
## Execution topology model
- Pipeline graph execution is DAG-based with ready-node frontiers.
@@ -52,6 +63,7 @@ Security enforcement now lives in `src/security`:
- Zod-validated shell/tool policy schemas.
- `SecurityRulesEngine` for binary allowlists, path traversal checks, worktree boundaries, and tool clearance checks.
- `SecureCommandExecutor` for controlled `child_process` execution with timeout + explicit env policy.
- `ResolvedExecutionContext.allowedTools` is used to filter provider-exposed tools before SDK invocation, including Claude-specific tool gating where shared `enabled_tools` is ignored.
`PipelineExecutor` treats `SecurityViolationError` via configurable policy:

State and project-context writes are now atomic via temp-file + rename.

## Tool enforcement guarantees
- Pipeline resolves a flat `allowedTools` list per node attempt.
- MCP config exposed to executors is pre-filtered to `allowedTools`.
- Claude tool callbacks are expected to use the provided policy handler so unsupported shared MCP tool filters cannot bypass enforcement.
