From 93d682f19e0bc21ae21857ac8325e884d3b96d51 Mon Sep 17 00:00:00 2001 From: Alex Date: Fri, 15 May 2026 12:55:28 +0100 Subject: [PATCH 01/13] chore(workspace): unblock pre-commit hook for hardening branch Three pre-existing failures on main blocking the pre-commit hook; this branch needs them resolved before adding RLM hardening commits. 1. Five orchestrator integration tests construct OrchestratorConfig literally and were not updated when GiteaSkillRepoConfig was added in 2d41798c. Add gitea_skill_repo: None to each fixture. 2. main.rs:4240 was added in 2d41798c (#1486) calling api.get_thesaurus(&role_name) where role_name is &RoleName but the method expects &str. Also moved role_name twice into SearchQuery. Smallest fix: clone() at the SearchQuery moves and pass role_name.as_str() to get_thesaurus. The whole block is replaced wholesale in the upcoming concepts_matched helper extraction, so this is a temporary unblocker. 3. terraphim_service llm::router_config tests share process env: test_env_overrides sets LLM_PROXY_URL without serialising against test_merged_config_from_role, so parallel execution caused the latter to read the override and fail. Mark both #[serial] and add a defensive remove_var at the start of test_merged_config_from_role. cargo check --workspace --all-targets and cargo test -p terraphim_service --lib llm::router_config are clean after these changes. --- crates/terraphim_agent/src/main.rs | 6 +++--- .../tests/auto_merge_execution_tests.rs | 1 + crates/terraphim_orchestrator/tests/auto_merge_tests.rs | 1 + crates/terraphim_orchestrator/tests/orchestrator_tests.rs | 1 + .../tests/pause_and_breaker_tests.rs | 1 + crates/terraphim_orchestrator/tests/provider_gate_tests.rs | 1 + crates/terraphim_service/src/llm/router_config.rs | 7 +++++++ 7 files changed, 15 insertions(+), 3 deletions(-) diff --git a/crates/terraphim_agent/src/main.rs b/crates/terraphim_agent/src/main.rs index 4f0fb4d92..f0a1dcbed 100644 --- a/crates/terraphim_agent/src/main.rs +++ b/crates/terraphim_agent/src/main.rs @@ -4140,7 +4140,7 @@ async fn run_server_command( operator: operator.map(|op| op.into()), skip: Some(0), limit: Some(limit), - role: Some(role_name), + role: Some(role_name.clone()), layer: Layer::default(), include_pinned, min_quality, @@ -4153,7 +4153,7 @@ async fn run_server_command( operator: None, skip: Some(0), limit: Some(limit), - role: Some(role_name), + role: Some(role_name.clone()), layer: Layer::default(), include_pinned, min_quality, @@ -4237,7 +4237,7 @@ async fn run_server_command( }) .collect();

Snapshot operations now return RlmError::NotSupported instead of fabricating a SnapshotId for a no-op, giving callers an honest signal that VM-style state versioning is unavailable on this backend. Adds ExecutionEnvironment::end_session(&SessionId) trait method with a default Ok(()) impl, so backends with per-session resources (Docker) can override without disturbing existing impls. Removes the unused output_dir field and the unnecessary SessionId clone. Tests: 7 unit tests in local.rs (timeout-honoured, child-killed, snapshots-not-supported, end-session-default), 1 in error.rs (NotSupported error code, display, retryability).

Concurrent execute_* calls for the same session_id now serialise on the per-session Mutex; only one container is created. Adds DockerExecutor::release_session_container(&SessionId) inherent method, mirroring FirecrackerExecutor::release_session_vm. Also wires ExecutionEnvironment::end_session to call it, so the supervisor can release containers via the trait when needed. Adds default_host_config() applying the permissive profile per 2026-05-15 design decision: 512 MiB memory cap, 256 PIDs cap, all caps dropped, network=bridge (LLM bridge / pip use), readonly_rootfs=false (Python /tmp writes). Replaces sleep 3600 keepalive with sleep infinity so the container outlives any reasonable session and is torn down only by release_session_container, cleanup, or Drop. Replaces snapshot method bodies with RlmError::NotSupported. Replaces `as i32` cast on bollard's i64 exit code with i32::try_from. Removes the #[allow(dead_code)] attribute on the struct (project rule: no dead code) and the now-redundant config field. Tests: 8 in docker.rs (6 daemon-free, 2 gated on --ignored): host config profile, snapshots-not-supported, release-unknown-returns-none, release-removes-and-recreates, concurrent-ensure-no-leak.

The E2B arm previously logged "Selected E2B backend" then fell through without continuing, misleading operators reading logs. Now logs at debug! and explicitly continues to the next backend. 2. The Docker arm previously short-circuited the entire fallback chain if DockerExecutor::new returned Err (e.g. CLI present, daemon unreachable). Now logs at warn!, pushes to `tried`, and continues to the next backend so Local remains selectable. 3. The Local arm previously logged "Selected Local backend (no isolation)" at info! - falling back to no-isolation is a security-posture downgrade and should be visible in production logs. Now logs at warn! including the `tried` context so operators can see why the secure backends were unavailable. Also caches `is_docker_available()` once per call (avoiding repeated ~50-100ms shell-outs to `docker --version`) and tightens the helper log to "CLI not present" since it does not actually probe the daemon. Tests: 2 new unit tests in mod.rs (Local-preference returns Local, E2B-unimplemented falls through to Local).

Replaces inline blocks at main.rs:2177-2182 (offline) and 4247-4268 (server) with the new helpers. The server-mode call site previously assigned 1u64 to every reconstructed NormalizedTerm; the new with_auto_id reconstruction is semantically honest. Both sites log thesaurus failures at debug! instead of silently swallowing them. The /thesaurus/{role} HTTP API stays untouched.

The hook now works on macOS without `brew install coreutils`. - Drop the `2>/dev/null` redirect on the MCP invocation so operators retain stderr for debugging failed calls. install.sh now warns (does not block) if `jq` is missing. README.md documents the `jq` dependency, macOS portability, the known-limitation of the JS plugin's per-call MCP-server spawn, and the new tests/test_hook.sh smoke-test entry point. tests/test_hook.sh exercises the hook with a quoted prompt (asserts the captured payload is valid JSON), a passthrough non-RLM command, and the portable timeout wrapper on a stripped PATH that excludes GNU timeout / gtimeout. Tests stub $TERRAPHIM_MCP so no live MCP server is needed.

P1 fixes: 1. Wire end_session trait method through TerraphimRlm::destroy_session (rlm.rs:194). FirecrackerExecutor overrides end_session to call the inherent release_session_vm, so destroying a session now releases per-backend resources via a single trait call. Adds a regression test (test_destroy_session_calls_executor_end_session) that uses an instrumented MockExecutor with an AtomicUsize counter. 2. Fix run_with_timeout PID-reuse race in terraphim-rlm-hook.sh by running the child in its own process group (setsid where available) and targeting kill at the negative pgid instead of a recyclable pid. Falls back to plain pid kill on systems without setsid. P2 fixes: 3. Drop #[ignore] from the two real-Docker integration tests (test_docker_concurrent_ensure_no_leak and test_docker_release_session_container_removes). Add a skip_unless_image_ready helper that gates on both daemon presence AND the default image being cached locally; tests skip cleanly with a hint to `docker pull` if the image is missing. 4. Hook smoke test now also asserts prompt content fidelity (prompt_content_roundtrip) by extracting params.arguments.prompt from the captured payload and comparing it byte-for-byte to the original input. Replaces the awk-based RLM args extractor with bash parameter expansion that preserves whitespace and literal quotes. 5. Force run_with_timeout test 3 to actually exercise the portable wrapper on Linux by staging a private $PATH (only sleep, kill, bash, sh, dash, setsid, grep, cut, head; no timeout / gtimeout) and sourcing the function definitions directly from the hook script. Test no longer self-skips on systems shipping GNU coreutils. 5a. Add DockerExecutor::with_host_config(HostConfig) builder so callers can override the permissive default profile (network=bridge, readonly_rootfs=false). Test confirms override propagates. 5c. Replace the 200ms fixed sleep in test_local_kills_on_timeout with a bounded pgrep poll (50ms backoff up to 2s). Marker now includes a Ulid so concurrent test runs don't collide. 5d clippy: convert five `let mut x = T::default(); x.field = ...` patterns to struct-update syntax, silencing the field_reassign_with_default warnings. Test count: 128 in terraphim_rlm lib (was 126), 4 in hook smoke tests (was 3). Zero clippy warnings on touched crates. cargo fmt clean. --- crates/terraphim_rlm/src/executor/docker.rs | 77 +++++++++++++-- .../terraphim_rlm/src/executor/firecracker.rs | 10 ++ crates/terraphim_rlm/src/executor/local.rs | 61 ++++++++---- crates/terraphim_rlm/src/executor/mod.rs | 14 ++- crates/terraphim_rlm/src/rlm.rs | 45 +++++++++ .../opencode-plugin-rlm/terraphim-rlm-hook.sh | 45 +++++++-- .../opencode-plugin-rlm/tests/test_hook.sh | 99 ++++++++++++++----- 7 files changed, 284 insertions(+), 67 deletions(-) diff --git a/crates/terraphim_rlm/src/executor/docker.rs b/crates/terraphim_rlm/src/executor/docker.rs index 969222802..f58e48025 100644 --- a/crates/terraphim_rlm/src/executor/docker.rs +++ b/crates/terraphim_rlm/src/executor/docker.rs @@ -48,6 +48,10 @@ pub struct DockerExecutor { /// is `None` until the container is created and published. session_to_container: DashMap>>>, image: String, + /// HostConfig applied to every session container.

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`. Resource limits live under `ContainerCreateBody.host_config: Option` (memory, `pids_limit`, `cap_drop`, `network_mode`, `read_only_root_filesystem`). +- **dashmap 6.1** — already a dependency of `terraphim_rlm` (`Cargo.toml:52`); supports `entry().or_insert_with` patterns suitable for per-session locking. +- **tokio 1.x** — `Command::kill_on_drop(true)` exists and is the idiomatic fix for the LocalExecutor child leak. +- **`/thesaurus/{role}` endpoint** — `terraphim_server/src/api.rs:1641` returns lossy `HashMap`; agent client mirrors this in `crates/terraphim_agent/src/client.rs:198`. +- **`NormalizedTerm::with_auto_id`** — `crates/terraphim_types/src/lib.rs:349` already provides a unique-id constructor we can use to avoid the `id=1u64` collision. + +## Constraints + +### Technical Constraints + +- **No new dependencies**: the project's disciplined-development culture (and the prior robustness pass plan) explicitly forbids adding crates for these fixes. `dashmap`, `tokio`, `bollard`, `terraphim_automata` are sufficient. +- **No mocks in tests**: per the user's project rule (`CLAUDE.md`). Docker tests must gate on real daemon availability (existing pattern in `docker.rs::tests::is_docker_available`); LocalExecutor tests use real `bash`/`python3`. +- **No `timeout` shell command**: per the user's global rule. Hook script must use a POSIX-portable construct. +- **No dead code**: per the user's global rule. `#[allow(dead_code)]` on `DockerExecutor` struct must go. +- **No emoji in code/docs**: per global rule (already adhered to here). +- **British English**: per global rule (used throughout this doc). +- **Trait stability**: changing `ExecutionEnvironment` is invasive (six implementations: docker, local, firecracker, ssh, e2b stub, mock in `rlm.rs:881`). 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. We can sequence small commits. + +### Non-Functional Requirements + +| Requirement | Target | Current | +|---|---|---| +| Concurrent session container creation | 0 leaks | 1 leak per concurrent racer | +| `ctx.timeout_ms` honoured (Local) | Yes | No (hardcoded 30 s) | +| Zombie processes from LocalExecutor timeouts | 0 | 1 per timeout | +| Backend fallback after Docker init Err | Falls through to next | Errors out | +| Hook script compatible with macOS | Yes | No (GNU `timeout`) | +| Server-mode `concepts_matched` parity with offline | Identical | Off — id collision, no log on Err | + +## Vital Few (Essentialism) + +### Essential Constraints (Max 3) + +| Constraint | Why It's Vital | Evidence | +|---|---|---| +| **No new public API on `ExecutionEnvironment` trait unless mandatory** | Trait change touches 6 implementations including a mock in `rlm.rs:881`; ripple is large for what is mostly per-backend cleanup. | `grep "impl ExecutionEnvironment"` returns 6 hits. | +| **No new dependencies** | Prior robustness pass (`implementation-plan-docker-executor-robustness.md`, "Avoid At All Cost") set this norm; everything we need is already in the workspace. | Cargo.toml inspection confirms `dashmap`, `tokio`, `bollard`, `terraphim_automata` available. | +| **No regressions to Firecracker path** | Firecracker is the "real" isolation backend; Docker/Local are convenience/dev backends. Don't perturb VM lifecycle semantics or `release_session_vm` contract. | `release_session_vm` is consumed by tests and supervisor; out of scope to change. | + +### Eliminated from Scope + +| Eliminated Item | Why Eliminated | +|---|---| +| Container pooling / pre-warm in `DockerExecutor` | Already explicitly out-of-scope per the prior robustness plan; not in the review findings. | +| Image pre-pull in `DockerExecutor` | Same as above. | +| Real snapshot support in Docker/Local | Snapshot story belongs to Firecracker; Docker/Local should honestly say "not supported" (a small fix, not a feature build-out). | +| Extending `/thesaurus/{role}` API to include IDs/URLs | Public-API change with frontend impact. 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. Capture as `Open Question 2`. | +| Rewriting `terraphim-rlm.js` plugin | The double-spawn issue is real but limited to an example; flag, fix the most-egregious bits, defer architectural rewrite. | +| Adding `shellcheck` to CI | Useful but a CI/infra change; defer to a separate cycle. Suggested as a follow-up in the review. | + +## Dependencies + +### Internal Dependencies + +| Dependency | Impact | Risk | +|---|---|---| +| `terraphim_agent_supervisor` | Consumes `release_session_vm`; will need to call analogous `release_session_container` if we add it. | Low — additive. | +| `terraphim_automata::find_matches` | Used by both `concepts_matched` paths; signature must accept `Thesaurus`. | None — reusing existing API. | +| `terraphim_types::NormalizedTerm::with_auto_id` | Pre-existing helper that solves the id-collision symptom. | None — already used elsewhere in workspace. | +| `terraphim_orchestrator::config::GiteaSkillRepoConfig` | Token redaction touches struct definition; consumers do `Debug`-print. | Low — `Debug` impl change only. | + +### External Dependencies + +| Dependency | Version | Risk | Alternative | +|---|---|---|---| +| `bollard` | 0.20 | Low — `HostConfig` is stable across 0.x. | None needed. | +| `dashmap` | 6.1 | Low — already in workspace. | `tokio::sync::Mutex>` (slower under contention). | +| `tokio::process::Command::kill_on_drop` | 1.x | Low — stable since 1.0. | Manual `child.kill()` in timeout branch. | + +## Risks and Unknowns + +### Known Risks + +| Risk | Likelihood | Impact | Mitigation | +|---|---|---|---| +| Adding `kill_on_drop(true)` masks a legitimate use case (long-running backgrounded process) | Low | Med | LocalExecutor is documented as no-isolation dev/test backend; long-running detached jobs are not its use case. Document the choice in the doc-comment. | +| Per-session DashMap lock leaks an entry per session | Med | Low | Add `release_session_container` that removes the entry. Existing `cleanup()` already drains, so leakage is bounded by session count. | +| Adding `host_config` resource limits breaks existing tests that rely on default permissive container | Low | Low | Existing tests only assert capabilities and health-check; resource limits are additive and don't affect those. | +| `with_auto_id` for server-mode `Thesaurus` reconstruction still loses URL/action/priority | Low | Low | `find_matches` only consumes term values for the automata; URL/action are not needed for `concepts_matched`. Document this. | +| Adding a `release_session_container` inherent method drifts from `release_session_vm` naming | Low | Low | Use `release_session` as the symmetric name on both backends in a follow-up rename (mark as out-of-scope here, name it `release_session_container` to match the `_container` mental model used in this file). | +| Hook script POSIX timeout substitute (`( cmd & PID=$!; sleep 30 && kill $PID )`) misbehaves under `set -e` | Med | Low | Wrap in subshell with explicit error handling; cover with bats-style fixture test. | + +### Open Questions + +1. **Should `ExecutionEnvironment` grow an `end_session(SessionId)` method?** The supervisor would benefit from a uniform hook, but no current call-site demands it. **Recommendation**: defer; add as inherent method on `DockerExecutor` matching `release_session_vm` pattern. **Resolver**: Alex. +2. **Should `select_executor` move to a capability-driven matcher?** The current enum-arm matching makes the E2b-fallthrough bug easy to write. **Recommendation**: defer to a separate cycle; in this cycle, fix the immediate bugs and add `log::warn!` on insecure fallback. **Resolver**: Alex. +3. **Should `/thesaurus/{role_name}` API be enriched to return `Vec` instead of `HashMap`?** Would let the agent reconstruct a faithful `Thesaurus`. **Recommendation**: defer; the immediate fix uses `with_auto_id` (lossless for matching). 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. No language switch required. +5. **The `Local` backend is honestly named "no isolation"** in its own doc-comment. Logging `info!` on selection is wrong — fall-back to no-isolation is a security-posture downgrade and should be `warn!`. +6. **`with_auto_id`** (`types/lib.rs:349`) already exists for this exact "I have a string, I need a `NormalizedTerm`" use case.
