mistral_request

Previous value: -"Slice λ: run this request inside a dedicated git worktree owned by the gateway. `true` creates a fresh worktree at `<repoRoot>/.worktrees/<uuid>` branched from HEAD. `{ name?, ref? }` lets the caller supply a sanitized name and/or a git ref (default: HEAD). When the request carries a sessionId and the session already has a worktree, reuse requires same-host ownership metadata and a matching live Git registration. Named path collisions never reuse manager state. Gateway-managed worktrees require the local file-backed session manager and fail closed with PostgreSQL sessions. The Grok, Devin, and Mistral adapters require an explicit provider-native sessionId; fresh, createNewSession, and resumeLatest-only worktree requests fail closed because they cannot durably reselect the worktree. The request must select a registered workspace explicitly, through caller-owned session metadata, or through the configured default. Worktrees never fall back to the gateway process cwd and cannot be combined with local workingDir, addDir, or includeDirs paths. The gateway spawns the child CLI with `cwd: <worktree-path>`; no `-w`/`--worktree` flag is ever emitted to the underlying CLI. On worktree materialization, the gateway suppresses repository, system, and global Git hooks and configured clean, smudge, and process checkout filters, sparse checkout, and lazy object fetching. Filter-dependent content such as Git LFS remains in its repository representation instead of executing host commands. On session_delete or TTL eviction the gateway hides the session and runs `git worktree remove --force`. Failed removal retains a durable cleanup-pending tombstone which blocks reuse and is retried when the file store is registered on the owning host. The tombstone is finalized only after verified Git removal. Successful responses are prefixed with `[gateway] worktree=<absolute-path>\\n` so callers can use the path. For Claude approvalStrategy:mcp_managed, requesting or reusing a worktree requires approval and LLM_GATEWAY_APPROVAL_ALLOW_BYPASS=1. Other adapters reject mcp_managed before launch. NOTE: callers should `.gitignore` the `.worktrees/` directory in their repo (the gateway does NOT auto-gitignore; see slice λ spec Q4)."New value: +"Slice λ: run this request inside a dedicated git worktree owned by the gateway. `true` creates a fresh worktree at `<repoRoot>/.worktrees/<uuid>` branched from HEAD. `{ name?, ref? }` lets the caller supply a sanitized name and/or a git ref (default: HEAD). When the request carries a sessionId and the session already has a worktree, reuse requires same-host ownership metadata and a matching live Git registration. Named path collisions never reuse manager state. Gateway-managed worktrees work with file-backed and PostgreSQL session managers. Shared PostgreSQL rows do not transfer filesystem ownership; reuse and cleanup remain limited to the owning host.

Filter-dependent content such as Git LFS remains in its repository representation instead of executing host commands. On session_delete, session_clear_all or file-backed TTL eviction, both managers hide a durably owned worktree session while cleanup runs. Failed Git removal retains a cleanup-pending tombstone, blocks reuse, and is retried when a manager is registered on the owning host; the record is finalized only once Git no longer registers the worktree, which is read back rather than inferred from the recorded path being absent. A worktree that moved, or whose owner marker cannot be read, is not a removal. Deletion processed by another host removes no worktree and leaves the owning host's record intact. The database-side cleanup_expired_sessions function stages the same tombstone instead of deleting a worktree-bearing session; it invokes no gateway observer and so attempts no removal itself. A tombstone is not bounded by retention. Successful responses are prefixed with `[gateway] worktree=<absolute-path>\\n` so callers can use the path.
