Each fix is local to one file and most are 5-30 lines: + +- `LocalExecutor` timeout: change one constant + one method call (`kill_on_drop(true)`). ~10 lines. +- `DockerExecutor` per-session lock: replace one `parking_lot::RwLock` with `dashmap::DashMap` and rewrite `ensure_container` (~25 lines). +- `DockerExecutor` host_config: add a `default_host_config()` helper and pass it in `create_container` (~30 lines). +- `select_executor` fixes: three small surgical edits (~15 lines). +- `concepts_matched` helper: extract a private `compute_concepts_matched` function and call it from both branches (~30 lines, mostly deletion). +- Hook script: rewrite four small JSON-builder calls and one timeout invocation (~30 lines). +- Config: add a `Debug` impl and a `Default` for `cache_dir` (~10 lines). + +**Senior Engineer Test**: Would a senior engineer call this overcomplicated? No — these are textbook fixes for textbook bugs. The only judgment call (per-session lock pattern) is the cheapest correct option using a dependency we already have. + +**Nothing Speculative Checklist**: +- [x] No features the user didn't request — every change traces to a review finding. +- [x] No abstractions "in case we need them later" — `release_session_container` is inherent, not on the trait, until a second caller appears. +- [x] No flexibility "just in case" — resource limits are hardcoded sensible defaults, not configurable. +- [x] No error handling for scenarios that cannot occur — DashMap entry creation is infallible. +- [x] No premature optimization — DashMap is the cheapest correct primitive; no benchmark-driven choices. + +## File Changes + +### New Files + +None. + +### Modified Files + +| File | Changes | +|---|---| +| `crates/terraphim_rlm/src/executor/local.rs` | Honour `ctx.timeout_ms`; `kill_on_drop(true)`; remove `output_dir` field + `with_output_dir`; return `RlmError::NotSupported` from snapshot methods; drop redundant `_session_id.clone()`; add `test_local_honours_timeout`, `test_local_kills_on_timeout`, `test_local_snapshot_returns_not_supported`. | +| `crates/terraphim_rlm/src/executor/docker.rs` | Replace `session_to_container: parking_lot::RwLock>` with `DashMap>>>`; rewrite `ensure_container` to be race-free; add `release_session_container(&SessionId)` inherent; add `default_host_config()` helper and pass into `create_container`; replace `sleep 3600` with `sleep infinity`; remove `#[allow(dead_code)]`; replace `as i32` with `i32::try_from`; return `RlmError::NotSupported` from snapshot methods; add `test_docker_concurrent_ensure_no_leak`, `test_docker_release_session_container`, `test_docker_resource_limits_applied`, `test_docker_snapshot_returns_not_supported`. | +| `crates/terraphim_rlm/src/executor/mod.rs` | Fix E2B arm to log `debug!` and `continue`; fix Docker arm to push to `tried` and `continue` on `DockerExecutor::new` Err; warn-log on Local fallback. | +| `crates/terraphim_rlm/src/error.rs` | Add `NotSupported { backend: String, op: String }` variant; add JSON-RPC error code `-32070`; mark non-retryable. | +| `crates/terraphim_agent/src/main.rs` | Extract `async fn compute_concepts_matched_offline(service, role, query)` and `async fn compute_concepts_matched_server(api, role, query)`; server variant uses `with_auto_id`; both log `debug!` on Err; replace inline blocks at lines 2177-2183 and 4240-4263. | +| `crates/terraphim_agent/tests/robot_search_concepts_matched_test.rs` | New regression test asserting offline/server parity for a fixed thesaurus + query (uses real ripgrep haystack, no mocks). | +| `examples/opencode-plugin-rlm/terraphim-rlm-hook.sh` | Replace `call_mcp_tool` JSON construction with `jq -n --arg`; replace `timeout 30` with portable POSIX wrapper; harden `awk`-based parsing for quoted args. | +| `examples/opencode-plugin-rlm/install.sh` | Add `jq` dependency check (warn but do not block); document macOS portability. | +| `examples/opencode-plugin-rlm/README.md` | Document `jq` requirement; note macOS support. | +| `crates/terraphim_orchestrator/src/config.rs` | Implement manual `Debug` for `GiteaSkillRepoConfig` redacting `token`; change `cache_dir` default to `dirs::cache_dir().unwrap_or_else(env::temp_dir).join("terraphim/skills")` via a `default_cache_dir()` helper. | + +### Deleted Files + +None. + +## API Design + +### Public Types + +No new public types in `terraphim_rlm` (one new private helper). + +In `RlmError`: +```rust +#[derive(Debug, thiserror::Error)] +pub enum RlmError { + // ... existing variants ... + + /// Operation is not supported by the selected backend. + #[error("backend '{backend}' does not support operation '{op}'")] + NotSupported { + backend: String, + op: String, + }, +} +``` + +### Public Functions + +**New inherent on `DockerExecutor`** (mirrors `FirecrackerExecutor::release_session_vm`): +```rust +impl DockerExecutor { + /// Release the container associated with `session_id`, removing it from + /// Docker and from the internal session map.

All issues are independent fixes within already-merged code; none require architectural rework. This phase scopes the problem set, confirms the API surface available for fixes, and identifies the only true unknowns: whether the trait should grow an `end_session` hook and whether the `/thesaurus/{role}` endpoint should be enriched. + +## Essential Questions Check + +| Question | Answer | Evidence | +|---|---|---| +| Energizing? | Yes | Recently-landed code with named follow-ups; clear "fix what we just shipped" loop. | +| Leverages strengths? | Yes | Touches Rust async/concurrency, executor abstraction, automata search — all areas with established repo patterns to mirror (Firecracker `release_session_vm`, `kill_on_drop` discipline elsewhere). | +| Meets real need? | Yes | Two failure modes (TOCTOU container leak, ignored timeout) are silent reliability bugs that will bite the moment RLM has more than one concurrent session. | + +**Proceed**: Yes (3/3 YES). + +## Problem Statement + +### Description + +The RLM executor surface (`crates/terraphim_rlm/src/executor/{docker,local,mod}.rs`), the supporting OpenCode/Claude Code hook example (`examples/opencode-plugin-rlm/`), and the agent's robot-mode `concepts_matched` fix (`crates/terraphim_agent/src/main.rs`) shipped with a set of correctness, lifecycle, and observability defects identified in the structural review of 2026-05-15. They are functionally correct in single-threaded happy-path tests but degrade under concurrency, contract-driven calls, or non-Linux environments. + +### Impact + +- **DockerExecutor**: container leaks under concurrent sessions; container persists for the full executor lifetime with no per-session release; no resource limits (memory, PIDs, caps), weakening the "container isolation" claim relative to Firecracker; hardcoded `sleep 3600` keepalive becomes a dangling reference after one hour. +- **LocalExecutor**: callers that pass a `timeout_ms` are silently ignored (always 30 s); timed-out child processes become orphans; `create_snapshot` returns a real-looking `SnapshotId` for an op that does nothing. +- **`select_executor`**: `E2b` arm logs "Selected" then falls through; Docker init failure short-circuits the fallback chain, masking `LocalExecutor` even when it is selectable. +- **`concepts_matched` server-mode**: every reconstructed `NormalizedTerm` collides on `id = 1u64`, breaking any downstream code that uses ID for indexing; same logic is duplicated between the offline and server branches. +- **`terraphim-rlm-hook.sh`**: GNU `timeout` (absent on macOS) breaks the hook on a primary developer platform; JSON built via shell interpolation breaks on any prompt containing `"` or `\`. +- **`GiteaSkillRepoConfig`**: `token: Option` will leak via `Debug`; `cache_dir: PathBuf` defaults to empty. + +### Success Criteria + +1. **Concurrency**: `DockerExecutor::ensure_container` is race-free under concurrent `execute_*` calls with the same `SessionId` (verified by a stress test, no orphan containers after run). +2. **Contract**: `LocalExecutor` honours `ctx.timeout_ms` and reaps timed-out children (verified by a unit test that asserts no zombie process and timely return). +3. **Lifecycle**: Sessions can release their container without tearing down the executor (verified by an inherent-method test mirroring `release_session_vm`). +4. **Selection**: With Docker daemon unavailable, `select_executor` returns `LocalExecutor` instead of erroring (verified by injection test). +5. **Semantic correctness**: server-mode `concepts_matched` returns identical values to offline-mode for the same role + query (verified by parity test). +6. **Portability**: hook script works on macOS without GNU coreutils and survives prompts with quotes (verified by `shellcheck` and a fixture test). +7. **Code hygiene**: zero new clippy warnings, zero `#[allow(dead_code)]`, zero unused fields. + +## Current State Analysis + +### Existing Implementation + +The RLM executor uses a `select_executor` factory that walks `RlmConfig::backend_preference` (default: Firecracker → E2B → Docker → Local). Each backend implements the `ExecutionEnvironment` trait (`crates/terraphim_rlm/src/executor/trait.rs`). Snapshot lifecycle is on the trait; per-session resource lifecycle is **not** — `FirecrackerExecutor` exposes an inherent `release_session_vm` method (`firecracker.rs:290`) consumed by the supervisor, but `DockerExecutor` has no equivalent, leaving the trait's snapshot methods to implicitly carry session-cleanup semantics they were not designed for. + +### Code Locations + +| Component | Location | Purpose | +|---|---|---| +| Trait definition | `crates/terraphim_rlm/src/executor/trait.rs:32-156` | `ExecutionEnvironment` trait | +| Execution context | `crates/terraphim_rlm/src/executor/context.rs:43-92` | `ExecutionContext` (has `timeout_ms`) | +| Firecracker backend | `crates/terraphim_rlm/src/executor/firecracker.rs` | Reference impl with `release_session_vm` | +| Docker backend | `crates/terraphim_rlm/src/executor/docker.rs` | Subject of fixes | +| Local backend | `crates/terraphim_rlm/src/executor/local.rs` | Subject of fixes | +| Backend selector | `crates/terraphim_rlm/src/executor/mod.rs:80-143` | `select_executor` | +| Error variants | `crates/terraphim_rlm/src/error.rs` | Has `NoBackendAvailable`, lacks `NotSupported` | +| Robot search envelope | `crates/terraphim_agent/src/main.rs:2160-2200, 4220-4275` | Two `concepts_matched` populate sites | +| Thesaurus API server | `terraphim_server/src/api.rs:1639-1726` | Only returns `HashMap` (lossy) | +| `NormalizedTerm` | `crates/terraphim_types/src/lib.rs:303-345` | Has `with_auto_id` helper (line 349) | +| Hook script | `examples/opencode-plugin-rlm/terraphim-rlm-hook.sh` | Subject of fixes | +| Plugin JS | `examples/opencode-plugin-rlm/terraphim-rlm.js` | Subject of fixes | +| Skill repo config | `crates/terraphim_orchestrator/src/config.rs:222-260` | `GiteaSkillRepoConfig` | + +### Data Flow + +`Caller → select_executor(config) → DockerExecutor.execute_code(code, ctx)` + → `ensure_container(session_id)` → (TOCTOU window) → bollard create+start + → `exec_in_container(container_id, cmd, ctx)` → `tokio::time::timeout(ctx.timeout_ms, stream)` + → `ExecutionResult { stdout, stderr, exit_code, timed_out }` + +`Caller → LocalExecutor.execute_code(code, ctx)` + → `build_python_command(code, ctx)` → `tokio::time::timeout(30_000ms_HARDCODED, cmd.output())` + → on timeout: future dropped, child not killed → orphan process. + +`Robot-search caller → run_server_command → api.get_thesaurus(role) → ThesaurusResponse{HashMap}` + → reconstruct `Thesaurus` with every `id = 1u64` → `find_matches(query, thesaurus)`. + +### Integration Points + +- **bollard 0.20** — `create_container`, `start_container`, `create_exec`, `start_exec`, `inspect_exec`, `remove_container`, `ping`.

Prefer inherent methods unless a cross-backend lifecycle hook is genuinely needed. +- **API stability**: extending `ThesaurusResponse` is a public-API schema change with frontend impact (the desktop UI consumes this endpoint). Prefer agent-side mitigation unless the lossy shape blocks other work. + +### Business Constraints + +- **No breaking changes** to the in-flight Firecracker path; all fixes must coexist with `FirecrackerExecutor` and the supervisor's `release_session_vm` consumer. +- **No timeline pressure**: these are post-merge follow-ups, not release blockers.

The agent-side mitigation (`with_auto_id` or skip the `Thesaurus` reconstruction entirely) is sufficient for `concepts_matched` correctness. Document as a follow-up if richer client needs emerge. | +| Changing `ExecutionEnvironment` trait | Mostly per-backend resource lifecycle; inherent methods suffice. Re-evaluate only if supervisor needs uniform `end_session(SessionId)` across backends — not currently demonstrated. | +| Refactoring `select_executor` to a capability-driven matcher | Suggested in the review as a follow-up; valuable but out of scope for this defect-driven cycle.

Track as a separate enhancement if frontend needs richer data. **Resolver**: Alex. +4. **Should `RlmError` grow a `NotSupported { backend, op }` variant?** Cleaner than returning a fake `SnapshotId`. **Recommendation**: yes — this is a small, additive variant that improves caller diagnostics. **Resolver**: Alex. +5. **Should `LocalExecutor`'s `output_dir` field be wired or removed?** Currently dead. **Recommendation**: remove; not used anywhere; if we need an output-spool dir later, reintroduce with consumers. **Resolver**: Alex. + +### Assumptions Explicitly Stated + +| Assumption | Basis | Risk if Wrong | Verified? | +|---|---|---|---| +| `DockerExecutor` uses bollard 0.20's `HostConfig`-via-`ContainerCreateBody.host_config` field for resource limits | bollard 0.20 changelog, generic Docker REST API knowledge | Need different field path; small fix | No — to verify in Phase 2 by reading bollard docs | +| `dashmap::DashMap>>` is the cheapest way to serialise per-key creation | Established repo pattern; dashmap is already a dep | If contention is high we may want a different scheme; doesn't break correctness | No — accept; benchmark if it bites | +| `tokio::process::Command::kill_on_drop(true)` is sufficient (no `prctl(PR_SET_PDEATHSIG)` style escalation needed) | tokio docs; LocalExecutor is single-process spawns of bash/python | Children of children survive (unlikely for python `-c` snippets) | No — accept; document | +| `find_matches` against a `Thesaurus` built with `with_auto_id` produces identical match output to one built with the original ids | `find_matches` consumes the automata which keys on term values, not ids | Match output diverges; parity test catches | No — to verify with the parity test in Phase 4 | +| Adding `host_config: Some(HostConfig{ memory, pids_limit, cap_drop, ... })` does not regress existing Docker test runs | Tests only assert capabilities and health-check (not resource consumption) | Tests fail in CI; revert and re-tune | No — to verify in Phase 4 | +| The structural-review-flagged `#[allow(dead_code)]` on `DockerExecutor` was added to silence a transient warning during the original PR | Removing it should produce zero warnings now that the struct is fully used | If a field is genuinely unread, will need to investigate | No — to verify in Phase 3 by removing and running clippy | + +### Multiple Interpretations Considered + +| Interpretation | Implications | Why Chosen/Rejected | +|---|---|---| +| **Fix `concepts_matched` server bug at the API layer (enrich `ThesaurusResponse`)** | Lossless data, no per-caller workaround | **Rejected for now**: schema change with frontend impact; defer to follow-up. The agent-side fix using `with_auto_id` is sufficient for `find_matches`. | +| **Fix `concepts_matched` at the agent layer using `with_auto_id`** | Cheap, local, semantically honest | **Chosen**: minimum viable correctness with no API impact. | +| **Fix `concepts_matched` by skipping `Thesaurus` reconstruction entirely** (call `find_matches` on a vec of strings, e.g., add a thin overload) | Avoids the question of identity altogether | **Considered, deferred**: would need a new `terraphim_automata` API; touches a stable public surface. The `with_auto_id` path uses existing API. | +| **`LocalExecutor` timeout: respect `ctx.timeout_ms` only** | Minimal change | **Chosen**, with the additional `kill_on_drop(true)` to fix the orphan-process issue. The two are coupled because honouring a tight timeout makes leaked children more visible. | +| **Add per-session lock for `DockerExecutor`: `dashmap::DashMap>>`** | Localised, no trait change | **Chosen**: matches the existing dashmap dependency; pattern used elsewhere in the repo. | +| **Add per-session lock: replace whole map with single `tokio::sync::Mutex>`** | Simpler code | **Rejected**: serialises all session ops, not just creation for a given session. Worse latency under load. | +| **Backend selection: capability matcher rewrite** | Future-proof; can't write the E2b-fallthrough bug | **Deferred**: bigger change; in this cycle just fix the immediate logic. | +| **Hook script: rewrite in Python** | Robust JSON via stdlib | **Rejected**: adds a runtime requirement; users may not have Python in PATH. Fix shell script with `jq -n --arg`. | +| **Hook script: ship two variants (linux/macos)** | Easy maintenance | **Rejected**: one well-written POSIX script is preferable. | + +## Research Findings + +### Key Insights + +1. **The "robustness pass" already established the right normative pattern** for DockerExecutor (Drop guards, `tokio::time::timeout` honouring `ctx.timeout_ms`, rollback-on-start-fail). The remaining work is to extend that discipline to (a) `LocalExecutor` and (b) container lifecycle/resource concerns that the prior pass declared out-of-scope but the structural review re-raised. +2. **The trait does not need to grow**. Both Firecracker (`release_session_vm`) and Docker (need `release_session_container`) carry per-session resource lifecycle as inherent methods consumed directly by the supervisor. Adding `end_session` to the trait is tempting but premature without a uniform call-site. +3. **The `concepts_matched` server bug is an artefact of a lossy API**, not a logic bug. The fix can be local (use `with_auto_id`) or systemic (enrich the API). Local is correct for this cycle; systemic is a separate enhancement. +4. **The hook script's bugs are 100% recoverable in shell** — `jq -n --arg` for safe JSON encoding, a portable timeout pattern, and `shellcheck` cleanup.
