Retry/escalation can be added later when #2672 replaces stubs. + - *Resolver*: Alex. + +### Assumptions Explicitly Stated + +| Assumption | Basis | Risk if Wrong | Verified? | +|---|---|---|---| +| `KnowledgeGraphValidator::validate` is the correct entry point (not `validate_with_context`). | Issue #2671 asks for blocking unsafe commands; retry/escalation is Step 5 (#2672). | Retry logic missing in first pass; acceptable per scope. | Yes — code inspection. | +| A validator with no thesaurus should not block execution. | `validator.rs:241` explicitly returns pass when `strictness == Permissive && thesaurus.is_none()`. For Normal/Strict without thesaurus, current code fails if `thesaurus.is_some()` is required. | Normal/Strict without thesaurus might incorrectly pass. | Yes — code inspection shows `if matched_terms.is_empty() && self.thesaurus.is_some()` guards. | +| The executor-context `ValidationResult` is the public API we must keep. | It is part of the `ExecutionEnvironment` trait and used by callers. | Breaking change if we replace it. | Yes — code inspection. | +| Validation should happen before building the execution context. | Simpler; no need to pass validation metadata through `ExecutionContext`. | Minor — could also be done inside executor methods. | Design choice; documented. | + +### Multiple Interpretations Considered + +| Interpretation | Implications | Why Chosen/Rejected | +|---|---|---| +| **A**: Validate inside each executor's `execute_code`/`execute_command` methods. | Centralised, no changes to `rlm.rs` or `query_loop.rs`; harder to surface rich errors. | Rejected — obscures the hot-path safety check and makes testing harder. | +| **B**: Validate in `TerraphimRlm` and `QueryLoop` before calling executor. | Explicit, testable, maps errors cleanly; requires executor to expose `validate`. | **Chosen** — matches issue #2671's stated target state and keeps safety visible at orchestrator level. | +| **C**: Replace executor-context `ValidationResult` with validator's `ValidationResult` everywhere. | Cleaner data model; breaks trait and all impls. | Rejected — too invasive for a P0 safety fix. | +| **D**: Add `validator: Arc` to `ExecutionContext`. | Keeps trait unchanged; validation available inside executor methods. | Rejected — `ExecutionContext` is serialised and should stay lightweight; validator is not serialisable. | + +## Research Findings + +### Key Insights + +1. **Validation is fully implemented but unconnected.** The `KnowledgeGraphValidator` already supports Permissive/Normal/Strict modes, match ratios, connectivity checks, and suggestions. The gap is purely wiring. +2. **Executor trait already has the hook.** `ExecutionEnvironment::validate` exists; we only need to give executors a validator instance and call it. +3. **`RlmError` already has the right variants.** `KgValidationFailed` and `KgEscalationRequired` exist and are wired to MCP error codes. +4. **Two `ValidationResult` types are a real hazard.** The trait uses the executor-context type; the validator returns its own type. A conversion function is required. +5. **Config does not currently carry a thesaurus.** We need a way to inject one or default to no validation. + +### Relevant Prior Art + +- `crates/terraphim_agent/src/commands/modes/hybrid.rs` already does risk assessment before executing commands; similar pattern. +- `crates/terraphim_lsp/src/server.rs` uses `terraphim_automata` matching for KG analysis. +- `.docs/implementation-plan-rlm-executor-hardening.md` establishes the norm of no trait changes and no new dependencies for RLM executor work. + +### Technical Spikes Needed + +| Spike | Purpose | Estimated Effort | +|---|---|---| +| Confirm `KnowledgeGraphValidator` can be built from a `Thesaurus` without a `RoleGraph` | Validate fallback path | 15 min | +| Measure validation latency with a 100-term thesaurus | Performance confidence | 30 min | + +## Recommendations + +### Proceed/No-Proceed + +**Proceed.** The problem is well-scoped, the validator exists, and the fix is additive wiring. This unblocks Step 5 and improves RLM safety. + +### Scope Recommendations + +- In scope: wiring validation into three hot paths, giving validators to executors, conversion helper, tests. +- Out of scope: retry loop, LLM rephrase, per-command strictness, metrics, trait changes. + +### Risk Mitigation Recommendations + +- Add unit tests that construct executors with a real thesaurus and assert blocked/allowed commands. +- Add integration tests in `rlm.rs` that call `execute_code`/`execute_command` with known/unknown terms. +- Keep Firecracker path untouched except for constructor wiring and the `validate` method body. + +## Next Steps + +1.

The existing `terraphim_service::llm::build_llm_from_role()` factory can construct clients (Ollama, OpenRouter, genai) but requires a `terraphim_config::Role`. The orchestrator has `CostFirst` routing at the provider level but not at the model level. We need to: (1) add `terraphim_config` as an optional dependency, (2) build a role config from environment/runtime detection, (3) select the cheapest available model within each provider, and (4) inject the client into RLM. + +## Essential Questions Check + +| Question | Answer | Evidence | +|----------|--------|----------| +| Energising? | Yes | Unblocks `rlm_query`, the deterministic-rlm-review skill, and the full RLM query loop | +| Leverages strengths? | Yes | Reuses existing `build_llm_from_role()`, `RouterBridgeLlmClient`, Ollama provider | +| Meets real need? | Yes | `rlm_query` currently returns `LlmNotConfigured`; without this, RLM cannot do LLM-based work | + +**Proceed**: Yes (3/3 YES) + +## Problem Statement + +### Description +RLM's LLM bridge has an injection point (`set_llm_client()`) but no auto-configuration mechanism.

Setting these to `"ollama"` and any valid model name produces a working `Arc`. + +2. **`CostFirst` routing at provider level, not model level**: The existing `RouterBridgeLlmClient` routes between PROVIDERS (Ollama vs OpenRouter) using cost levels. Within a single provider, model selection is static. For intra-provider model selection, we need custom logic. + +3. **Ollama `/api/tags` returns sizes**: The API response includes `size` (bytes) per model. We can query this, find the smallest chat-capable model, and use it. + +4. **Cheapest chat models**: `gemma3:270m` (292MB), `deepseek-coder:1.3b` (776MB), `gemma2:2b` (1.6GB). `all-minilm` (46MB) should be excluded as embedding-only. + +5. **RLM CLI already uses `RlmConfig::default()`**: The CLI binary has no provider configuration. We add auto-detection in `run()` after RLM construction. + +### Technical Spikes Needed + +| Spike | Purpose | Estimated Effort | +|-------|---------|------------------| +| Verify `terraphim_config` compiles as dep of `terraphim_rlm` | Confirm no version conflicts | 5 min | + +## Recommendations + +### Proceed/No-Proceed +**Proceed**.
