+# Build-Runner-LLM Proof
+
+**Issue**: 1423
+**Flow**: build-runner-llm-proof
+**Generated**: 2026-05-30 00:12 BST
+
+## What Was Proved
+
+1. **KG-first detection**: `scripts/build-runner-llm.sh` detects build commands
+   from BUILD.md > GitHub Actions > Cargo.toml fallback.
+
+2. **Command transformation**: terraphim-agent replace transforms tool commands
+   (npm → bun, pip → uv) via the Terraphim Engineer KG.
+
+3. **Whitelist validation**: Commands are validated against an allowlist before
+   execution. Blocked: sudo, curl|sh, rm -rf /.
+
+4. **LLM fallback on failure**: When a build step fails, claude --model haiku
+   diagnoses the failure and suggests a correction.
+
+5. **Self-healing BUILD.md**: The LLM correction is appended to BUILD.md
+   under an "Auto-corrected" timestamped section.
+
+## Script Location
+
+`scripts/build-runner-llm.sh` — 150-line bash script.
+
+## Architecture
+
+```
+Git Push → build-runner-llm.sh
+  ├─ detect_commands()     → BUILD.md / ci-pr.yml / Cargo.toml
+  ├─ transform_command()   → terraphim-agent replace (KG)
+  ├─ is_allowed()          → whitelist check
+  ├─ eval                  → execute
+  └─ on failure:
+       ├─ llm_correct_command() → claude --model haiku
+       └─ update_build_md()     → append to BUILD.md
+```
+
+## Known Gaps
+
+| Gap | Status |
+|-----|--------|
+| DevOpsRunner role not configured | KG transforms use general Terraphim Engineer role |
+| yq not installed locally | Falls back to hardcoded cargo commands |
+| BUILD.md has no ```bash build block | Detection falls through to fallback |
+| No cost tracking | bash.00 currently (no LLM cost logging) |
+| No commit status posting in local mode | GITEA_TOKEN not set for local runs |
+
+## Next Steps for Production
+
+1. Create DevOpsRunner role in `~/.config/terraphim/config.json`
+2. Populate `~/.config/terraphim/docs/src/kg/devops/` with build ontology
+3. Create dedicated bash block in BUILD.md: ```bash\ncargo fmt ...\n```
+4. Install yq for GitHub Actions parsing
+5. Wire cost tracking metrics
+6. Deploy to bigbox and restart orchestrator

+# Phase 2 Design: Spawn-Context Isolation Fix
+
+**Skill**: disciplined-design
+**Issue**: 1806
+**Date**: 2026-05-29
+
+---
+
+## 5/25 Rule: Explicitly Out of Scope
+
+| # | Thing not fixed | Reason |
+|---|----------------|--------|
+| 1 | `build_spawn_context_for_agent` signature | Adding a `working_dir` parameter would cascade changes across all 9 call sites and change a stable internal API; the two-line patch after the call is the minimal, contained fix |
+| 2 | `Provider.working_dir` redundancy | After the fix, `agent_working_dir` is stored in both `spawn_ctx.working_dir` and `Provider.working_dir`; removing the Provider field would touch the spawner config path and risk breaking fallback behaviour for non-project agents |
+| 3 | Haiku/review-tier worktree isolation | Review agents intentionally skip isolation (`needs_isolation = false`); this is a correct design choice, not a bug; changing it would increase resource consumption and is out of scope |
+
+---
+
+## Problem Summary
+
+`build_spawn_context_for_agent` constructs a `SpawnContext` whose `working_dir` field is set to the project root (`project.working_dir`) because at that point the worktree path has not yet been computed. Immediately after that call, the orchestrator allocates a git worktree and stores the resulting path in `agent_working_dir`, then places it on `Provider.working_dir`. However, the spawner's priority rule gives `spawn_ctx.working_dir` the highest precedence over `config.working_dir`, so the stale project-root value silently wins and the agent process is launched in the project root instead of the isolated worktree. The env var `ADF_WORKING_DIR` received the same stale value, so shell scripts inside the agent also operated on the live repository.
+
+---
+
+## Architecture
+
+### Before (bug)
+
+```
+build_spawn_context_for_agent()
+  +-- spawn_ctx.working_dir = project_root   <-- stale, set too early
+  +-- ADF_WORKING_DIR      = project_root
+
+create_agent_worktree()
+  +-- agent_working_dir    = /.../.worktrees/agent-xyz
+
+Provider.working_dir      = agent_working_dir   (correct)
+spawn_ctx.working_dir     = project_root        (wins over Provider)
+                                 |
+                                 v
+spawner: ctx.working_dir wins  --> agent runs in PROJECT ROOT  [WRONG]
+```
+
+### After (fix)
+
+```
+build_spawn_context_for_agent()
+  +-- spawn_ctx.working_dir = project_root   (temporary, will be overwritten)
+
+create_agent_worktree()
+  +-- agent_working_dir    = /.../.worktrees/agent-xyz
+
+spawn_ctx.working_dir     = agent_working_dir   [OVERWRITE - 1 line]
+ADF_WORKING_DIR           = agent_working_dir   [OVERWRITE - 3 lines total]
+                                 |
+                                 v
+spawner: ctx.working_dir wins  --> agent runs in WORKTREE    [CORRECT]
+```
+
+---
+
+## File Changes
+
+| File | Change | Lines |
+|------|--------|-------|
+| `crates/terraphim_orchestrator/src/lib.rs` | Overwrite `spawn_ctx.working_dir` and `ADF_WORKING_DIR` with `agent_working_dir` after the worktree is allocated, before `spawn_with_fallback` | ~3 |
+
+No other file is modified.
+
+---
+
+## Proposed Change
+
+```rust
+// Before (line 2404-2405, pre-fix state at HEAD~1):
+let mut spawn_ctx =
+    build_spawn_context_for_agent(&self.config, def, self.output_poster.as_ref());
+// ADF_WORKING_DIR and spawn_ctx.working_dir both point to project root here.
+// spawn_with_fallback follows immediately.
+
+// After (lines 2404-2410, current committed fix):
+let mut spawn_ctx =
+    build_spawn_context_for_agent(&self.config, def, self.output_poster.as_ref());
+spawn_ctx.working_dir = Some(agent_working_dir.clone());          // line 2406
+spawn_ctx = spawn_ctx.with_env(                                   // line 2407
+    "ADF_WORKING_DIR",                                            // line 2408
+    agent_working_dir.to_string_lossy().into_owned(),             // line 2409
+);                                                                // line 2410
+```
+
+The insertion point is after line 2405 (after `build_spawn_context_for_agent` returns) and before the `if let Some(event) = synthetic_event` block at line 2411. `agent_working_dir` is in scope at this point, having been resolved at line 2329.
+
+---
+
+## Test Plan
+
+| Test | What it verifies |
+|------|-----------------|
+| `test_spawn_ctx_working_dir_set_to_agent_working_dir` (lib.rs:11956) | Simulates the before-state (project root in spawn_ctx), applies the two-statement fix, then asserts (1) `spawn_ctx.working_dir` equals the worktree path and (2) `ADF_WORKING_DIR` env override equals the worktree path string |
+
+The test is a synchronous unit test with no I/O, no mocks, and no external dependencies. It directly exercises the mutation logic and can be run with:
+
+```
+cargo test -p terraphim_orchestrator test_spawn_ctx_working_dir_set_to_agent_working_dir
+```
+
+---
+
+## Eliminated Options
+
+| Option | Why rejected |
+|--------|-------------|
+| Modify `build_spawn_context_for_agent` to accept `agent_working_dir` as a parameter | Would require changing the function signature and all call sites. The function is called in multiple paths; this refactoring is disproportionate to the single-path fix needed for worktree isolation. |
+| Move worktree allocation before `build_spawn_context_for_agent` | Worktree allocation is async and depends on model-tier resolution (`needs_isolation`), which itself requires the agent definition and config. Reordering these steps would interleave unrelated logic and widen the diff. |
+| Change spawner priority to prefer `config.working_dir` over `ctx.working_dir` | The spawner priority rule (`ctx > config > default`) is the correct design; callers that want to override the directory are expected to set `ctx.working_dir`. Inverting the priority would break every other caller that deliberately sets `ctx.working_dir`. |
+
+---
+
+## Rollback
+
+Revert the addition of lines 2406-2410 in `lib.rs`. The test at line 11956 should be removed in the same revert. No other files are touched.

+# Phase 1 Research: Spawn-Context Isolation Bug
+
+**Skill**: disciplined-research
+**Issue**: 1806
+**Date**: 2026-05-29
+
+---
+
+## Bug Confirmation
+
+**YES - the bug was real.** It is present in the committed code at `HEAD~1` and the fix is in the current uncommitted diff.
+
+### Evidence
+
+**Root-cause line (pre-fix):**
+`crates/terraphim_orchestrator/src/lib.rs:2404-2405` — `build_spawn_context_for_agent` constructs `spawn_ctx` with `working_dir = project.working_dir` (the project root), as seen at `lib.rs:643`:
+
+```rust
+let mut ctx = SpawnContext::with_working_dir(project.working_dir.clone())
+    .with_env("ADF_PROJECT_ID", pid)
+    .with_env("ADF_WORKING_DIR", working_dir_str); // project root, not worktree
+```
+
+**Priority rule (spawner):**
+`crates/terraphim_spawner/src/lib.rs:657-662` comments "Priority: ctx override > config working_dir > spawner default":
+
+```rust
+let working_dir = ctx
+    .working_dir
+    .as_ref()
+    .or(config.working_dir.as_ref())
+    .unwrap_or(&self.default_working_dir);
+```
+
+**Worktree path correctly placed on the Provider (not overriding ctx):**
+`lib.rs:2329` computes `agent_working_dir` = worktree path if available, else `repo_dir`.
+`lib.rs:2338` places `agent_working_dir` into `ProviderType::Agent { working_dir }`.
+`crates/terraphim_spawner/src/config.rs:59` maps that into `AgentConfig::working_dir`.
+
+So pre-fix, the conflict was:
+- `spawn_ctx.working_dir` = project root (from `build_spawn_context_for_agent`)
+- `config.working_dir` = worktree path (from `Provider.working_dir` → `AgentConfig`)
+- Spawner picks `ctx.working_dir` first → **agent ran in project root**
+
+**The fix (current uncommitted diff, `lib.rs:2406-2410`):**
+
+```rust
+spawn_ctx.working_dir = Some(agent_working_dir.clone());
+spawn_ctx = spawn_ctx.with_env(
+    "ADF_WORKING_DIR",
+    agent_working_dir.to_string_lossy().into_owned(),
+);
+```
+
+This overwrites the project-root value in `spawn_ctx` with `agent_working_dir` (the worktree), so `ctx.working_dir` now also points to the worktree.
+
+---
+
+## Root Cause
+
+Two-layer inconsistency introduced by the interaction between `build_spawn_context_for_agent` and the worktree allocation logic:
+
+1. **`build_spawn_context_for_agent` (lib.rs:643)** sets `spawn_ctx.working_dir = project.working_dir` — the project root — because at that point the worktree path has not yet been computed and injected.
+
+2. **`spawn_process` (spawner/src/lib.rs:658)** gives `ctx.working_dir` the highest priority, so the project-root value silently wins over the correctly set `Provider.working_dir` (worktree).
+
+3. **`ADF_WORKING_DIR` env var (lib.rs:645)** was also set to the project root string by `build_spawn_context_for_agent`, so the agent's shell scripts that rely on `$ADF_WORKING_DIR` also received the wrong directory.
+
+The worktree path IS computed correctly at `lib.rs:2319-2329`; the bug is that it was put on the `Provider` but not subsequently patched back onto `spawn_ctx`.
+
+---
+
+## Impact
+
+**What actually happens (pre-fix):**
+
+- `create_agent_worktree` creates an isolated git worktree at e.g. `/tmp/project/.worktrees/agent-abc123`.
+- The worktree path is stored in `agent_working_dir` and placed on `Provider.working_dir`.
+- `build_spawn_context_for_agent` creates `spawn_ctx` with `working_dir = /tmp/project` (root) and `ADF_WORKING_DIR=/tmp/project`.
+- `spawn_process` selects `ctx.working_dir` = `/tmp/project` as the `current_dir` for the child process.
+- The spawned agent process starts in the project root, not in the isolated worktree.
+- The agent may read/write files in the live project, defeating the isolation guarantee.
+- `$ADF_WORKING_DIR` inside the agent shell also points to the project root.
+
+**What should happen (post-fix):**
+
+- `spawn_ctx.working_dir` = worktree path.
+- `ADF_WORKING_DIR` env var = worktree path.
+- Agent process starts in the isolated worktree.
+- Changes are contained; the worktree guard handles cleanup after the agent exits.
+
+---
+
+## Existing Safeguards
+
+1. **WorktreeGuard (lib.rs:2321)**: Created alongside the worktree. Ensures cleanup on drop. It does NOT prevent the process from running in the wrong directory — it only cleans up the worktree after the agent finishes. So isolation failure is silent: the guard fires correctly but the agent already ran in the wrong place.
+
+2. **Haiku agents skip isolation (lib.rs:2298)**: Review-tier (haiku) agents set `needs_isolation = false`, so they never enter the worktree path at all. This is intentional and correct — it means the bug only affected implementation-tier (non-haiku) agents.
+
+3. **Provider `working_dir` (lib.rs:2338)**: The worktree path was correctly stored on the `Provider`, so it would have been used if `spawn_ctx.working_dir` had been `None`. The bug is specifically that `spawn_ctx.working_dir` was non-`None` (set to project root) and thus took precedence.
+
+---
+
+## Recommendation
+
+Replace the stale `spawn_ctx.working_dir` produced by `build_spawn_context_for_agent` with `agent_working_dir` immediately after the call, and update `ADF_WORKING_DIR` accordingly — exactly as the uncommitted diff at `lib.rs:2406-2410` does.
