Commands +run with the user's OS permissions, without an OS sandbox or per-command approval UI; +they can affect files outside the workspace. Their environment is allowlisted and +does not inherit provider credentials, Git overrides, startup hooks, or Ferrus authority. +External MCP peers receive only their explicitly configured environment. + +Standalone has no managed Git ownership. Its policy leaves staging, commits, reset, +and worktree management to the user unless explicitly requested. Do not run it against +a workspace concurrently edited by HQ, another harness, or another user. Standalone +sessions themselves share a machine-local advisory workspace lock, including when +different journal storage paths are selected; this is not an orchestration task lease. + +## Journals and continuation + +Default storage is `~/.ferrus/standalone//`. The ID comes from filesystem +directory identity, so case/normalization aliases share the same local workspace slot. +`--storage /absolute/private/directory` selects another storage directory whose parent +must exist; it must be outside the workspace. Storage is owner-only and bound to that +workspace. It contains no registry, task rows, or orchestration database. + +The existing append-only journal, checkpoint, output, and command-spool contracts apply: + +```text +/workspace.json +/workspace.lock +/nano/sessions//events.jsonl +/nano/sessions//commands/ +``` + +The separate workspace lock lives under `~/.ferrus/standalone/locks/`. Use +`--session-id NAME` for a known ID; otherwise Nano generates one and prints it to stderr. + +```sh +ferrus-nano --workspace /absolute/path/to/repository --resume PREVIOUS_ID \ + --prompt "Continue with the next change" +``` + +Continuation creates a new journal. It imports a bounded previous transcript as +untrusted historical user content, not as replayed tool calls or live provider state. +It retains cumulative token, model-turn, tool-call, and retry accounting; the explicit +new request resets no-progress tracking and gets a fresh per-attempt elapsed deadline. +An interrupted provider reservation is conservatively charged. Current settings and +scoped guidance are loaded again. Oversized history fails closed rather than being +silently dropped. + +Recovery repairs only an incomplete journal tail and seals an interrupted prior attempt. +It never re-executes recorded operations or trusts old PIDs. Pending/unknown effects, +unconfirmed commands, and incomplete/inconsistent output spools reject continuation +before inference. Reconcile them manually before starting fresh work. Confirmed exited, +cancelled, and timed-out commands require complete spools. Completed source journals +remain unchanged. + +## Optional local context + +Repository indexing is explicit and independent of Ferrus project configuration: + +```sh +ferrus-nano --workspace /absolute/path/to/repository --index-graph +ferrus-nano --workspace /absolute/path/to/repository --graph --prompt "Find the parser entry points" +``` + +`--index-graph` builds/refreshes `/repo-graph.db` and exits without loading +provider settings.

Each request pins the selected snapshot; +requested repository snippets pass the existing hash-verified content boundary. + +Retrieval does not rescan the full repository to claim freshness. External edits leave +freshness `unknown`; current file tools remain the source of workspace evidence. Nano +records known mutations before effects and blocks stale graph retrieval until explicit +reindex. Graph-disabled/missing/stale coverage uses labeled workspace fallback. Working +sets never reuse graph evidence as current without compatible verified revisions. + +An existing curated project-memory sidecar can be supplied read-only: + +```sh +ferrus-nano --workspace /absolute/path/to/repository \ + --memory-sidecar /absolute/path/to/project-memory.db \ + --memory-namespace local:ferrus --memory-project PROJECT_ID \ + --prompt "Inspect prior specification decisions" +``` + +The explicit namespace/project identify the sidecar's portable scope. Memory queries +pin its published revision, report freshness independently, and cross into repository +facts only through exact revision/snapshot link sets. Standalone does not discover, +index, or author memory sources. Memory source snippets have no standalone verified +content adapter yet; use structural memory context with `include_snippets = false`. +For `project_context_search`, `kinds` selects memory entity kinds in the memory domain +and repository node kinds in the repository domain. In `all`, recognized memory kinds +filter memory; other kind tokens filter repository nodes independently. + +Optional external peers use `mcp_config_file` in provider settings and the existing +[bounded MCP client](ferrus-nano-mcp.md). Managed-binding peers are omitted before +discovery and proxy setup.
