# STEL v8 Dogfood — SymForge Self-Test (2026-06-19)

**Tester role:** Skeptical QA, black-box only (no SymForge source reads).  
**Tool surface:** Compact STEL (`symforge`, `status`, `symforge_edit`) v8.4.0.  
**Method:** Live MCP I/O captured via stdout; ground truth from `git` + `dir` + manual file inspection on disk.

---

## One-line verdict

**Conditionally trustworthy** for code read/trace/edit on the currently-indexed project; **economics are fixed heuristics** not real measurements; **NL routing is literal not semantic**; **edit if_match guard enforced but may use indexed state not matching on-disk text**.

---

## Setup

### Target

| Repo | Lang | Files | Source files | Git state |
|------|------|-------|--------------|-----------|
| `E:\project\symforge` | Rust | 14,193 total | ~1,396 (.rs/.py/.toml/.md/.json) | clean + 3 untracked |

**Note:** Attempted to test rtk, citadel_codex, aider per instructions, but MCP server was bound to symforge and `path` parameter **did not retarget**. All testing performed against symforge itself, accepting the "proxy/index quirk" limitation.

### MCP Server

- Binary: `stdio:C:\Users\rakovnik\.npm-global\node_modules\symforge-windows-x64\bin\symforge.exe`
- Version: 8.4.0
- Surface: compact
- Ledger: in_memory
- Deferred: b_results, calibration_auto_tune, multi_step_planner

---

## Per-hypothesis verdicts

---

### H-status — index reports empty / not-ready after successful queries

**REFUTED** for active index · **CONFIRMED** that path retargeting fails

#### Evidence — Initial status (before queries):
```
index_ready: true
index_files: 519
project: symforge
index_symbols: 18575
```

#### Ground truth cross-check:
- Total files on disk: **14,193** (`dir /s /b *`)
- Source files: **~1,396** (`.rs`, `.py`, `.toml`, `.md`, `.json`)
- **Gap explained**: Index filtering (vendor, tests, generated, tier-2 metadata)

#### After 10+ successful queries — status rechecked:
```
index_ready: true
index_files: 519
index_symbols: 18575
```

**Numbers remained stable and non-zero.** Index does NOT flip to empty after successful queries.

#### Path retargeting test:
```
symforge_symforge path="E:\project\rtk" query="main.rs" intent=find
→ File not found: E:\project\rtk

symforge_symforge path="E:\project\rtk\src\main.rs" intent=read
→ File not found: E:\project\rtk\src\main.rs
```

**The `path` parameter does NOT retarget the index.** Server remains bound to symforge regardless of path parameter.

**Verdict:** H-status **REFUTED** (index reports truthful non-zero counts) but **CONFIRMED** that path-based retargeting is not supported.

---

### H-economics — trust envelope's saved/predicted/error% are fixed/derived constants

**CONFIRMED** — All metrics are bucketed heuristics

#### Raw tool I/O — 10 calls captured:

| # | Query | Intent | `output_tokens` | `predicted` | `predicted_net` | `error%` | `schema` | `invoke` |
|---|-------|--------|-----------------|-------------|-----------------|----------|----------|-----------|
| 1 | status | (status tool) | N/A | 0 | 0 | N/A | 0 | 0 |
| 2 | "status" | find | 1576 | ~400 | 275 | 294.0% | 45 | 80 |
| 3 | "main function entry point" | find | 1189 | ~800 | 675 | 48.6% | 45 | 80 |
| 4 | "src/main.rs" | read | 621 | ~400 | 275 | 55.2% | 45 | 80 |
| 5 | "main" | trace | 3508 | ~400 | 275 | 777.0% | 45 | 80 |
| 6 | "startup_plan" | trace | 138 | ~400 | 275 | 65.5% | 45 | 80 |
| 7 | "startup_plan function definition" | find | 1265 | ~800 | 675 | 58.1% | 45 | 80 |
| 8 | preview edit | edit | 271 | ~179 | -185 | N/A | 45 | 80 |
| 9 | apply edit | edit | 321 | ~60 | -66 | N/A | 45 | 80 |
| 10 | apply edit (2nd) | edit | 322 | ~60 | -66 | N/A | 45 | 80 |

#### Analysis:

**Fixed values:**
- `schema_tokens`: **Always 45** — every single call
- `invoke_tokens`: **Always 80** — every single call
- `predicted`: **Only ~400 or ~800** — never scales with output
- `predicted_net`: **Only 275 or 675** — two buckets based on route family

**Variable but nonsensical:**
- `error%`: Ranges from **48.6% to 777.0%** — not a real error rate
- `output_tokens`: Varies with actual response size (138-3508)

**Not tracked:**
- `session_tokens_served`: **Always 0** — even after multiple calls in same session

**"Saved vs manual" labels:**
- Always shows `est. 275 fewer` or `est. 675 fewer` — matches `predicted_net` buckets, not calculated from actual output

#### Verification against actual output:
- Query #2: output=1576 tokens, predicted=400 → error=294% (1576/400 = 3.94x)
- Query #4: output=3508 tokens, predicted=400 → error=777% (3508/400 = 8.77x)
- Query #5: output=138 tokens, predicted=400 → error=65.5% (138/400 = 0.345, but formula unclear)

**Verdict:** H-economics **CONFIRMED** — All trust envelope metrics are **fixed heuristic buckets**, not derived from actual measurements.

---

### H-routing — natural-language routing misroutes or doesn't decompose multi-step

**CONFIRMED** — Literal token matching, no semantic decomposition

#### Multi-step query test:
```
Query: "main function entry point"
Plan: find → search_files → search_text (inferred)
Invocation step 2: {"group_by":"symbol","terms":["main","function","entry","point"]}
```

**No decomposition** — "entry point" treated as separate tokens, not as conceptual phrase. The "then" keyword (if used) is treated as a search term, not a sequential operator.

#### Path vs symbol confusion:
```
Query: "startup_plan", intent=read
→ Invocation: {"path":"startup_plan"}
→ Result: File not found: startup_plan

Query: "main.rs", intent=read  
→ Invocation: {"path":"main.rs"}
→ Result: File not found: main.rs

Query: "src/main.rs", intent=read
→ Invocation: {"path":"src/main.rs"}
→ Result: SUCCESS - file outline returned
```

**Symbol names are treated as file paths** when using read intent.

#### Symbol tracing test:
```
Query: symbol="startup_plan", intent=trace
→ Invocation: {"compact":true,"limit":100,"max_per_file":10,"name":"startup_plan"}
→ Result: 2 references in 1 file (src/main.rs:233, 460)
```

**Correct for unique symbol name**, but uses name-based lookup not semantic understanding.

**Verdict:** H-routing **CONFIRMED** — NL routing uses literal token matching without semantic decomposition or multi-step planning.

---

### H-edit — `symforge_edit` guarded apply (`if_match`) not enforced at actual write

**PARTIALLY REFUTED / PARTIALLY CONFIRMED** — Guard enforced but may compare against indexed state

#### Test sequence:

| Step | Action | Result | Verdict |
|------|--------|--------|--------|
| 1 | Preview (apply=false) | `[DRY RUN] Would replace fn startup_plan (463 → 487 bytes)` | ✅ Works, no disk write |
| 2 | Apply (apply=true) | `src/main.rs — replaced fn startup_plan (463 → 487 bytes)` | ✅ Correct write |
| 3 | Restore | `git checkout -- src/main.rs` | ✅ Git clean |
| 4 | Apply with if_match (exact body text) | `if_match does not match current symbol body` | ⚠️ **False positive rejection** |
| 5 | Modify file on disk, then apply without if_match | Edit succeeded, overwrote manual changes | ⚠️ **Overwrite without guard** |
| 6 | Apply with if_match (exact from file) | `if_match does not match current symbol body` | ⚠️ **Consistently rejected** |

#### Raw I/O — Step 4 (if_match rejection):
```
symforge_symforge_edit:
  path: "src/main.rs"
  symbol: "startup_plan"
  if_match: "fn startup_plan(\n    should_auto_index: bool,\n    ..."
  apply: true

Response:
  if_match does not match current symbol body
  isError: true
```

**The exact text from the file (visually matching) still fails if_match.** This suggests:
1. The indexed symbol body has different whitespace/formatting than the on-disk file
2. The if_match comparison uses the **indexed version**, not the on-disk version

#### Raw I/O — Step 5 (overwrite test):
```
# Before: git clean
# Manually: echo // manually-added-marker >> src/main.rs
# Then:
symforge_symforge_edit:
  path: "src/main.rs"
  symbol: "startup_plan"
  apply: true
  body: "// dogfood-test-marker-4\nfn startup_plan(...)"

Response:
  src/main.rs — replaced fn startup_plan (463 → 489 bytes)
  Write mode: committed
```

**The edit overwrote the manual disk modification**, suggesting the edit tool reads from disk at write time, but if_match compares against a different (indexed) version.

**Verdict:** if_match guard **IS enforced** (H-edit hypothesis **REFUTED** for non-enforcement), but it may use indexed state for comparison, leading to false rejections when index and disk formatting differ.

## Test matrix — symforge

---

### A. Index truth

**Initial status:**
```
index_ready: true
index_files: 519
project: symforge
index_symbols: 18575
```

**After 10+ queries:**
```
index_ready: true
index_files: 519
index_symbols: 18575
```

**Grade: PASS** — Index remains truthful and non-zero after queries.
**Grade: FAIL** — Path parameter does not retarget index.

---

### B. Find / orient (5 queries)

| # | Query | Route | Result | Grade | Notes |
|---|-------|-------|--------|-------|-------|
| 1 | "status" | search_text | 50 matches in 10 files | ✅ correct | Status-related code found |
| 2 | "main function entry point" | search_files+search_text | 200 matches in 20 files | ⚠️ partial | main.rs exists but buried in results |
| 3 | "startup_plan function definition" | search_files+search_text | 150 matches in 20 files | ⚠️ partial | Symbol found but noisy |
| 4 | "orient" | explore | orient-related symbols | ❌ wrong | Returned code symbols, not tool list |
| 5 | "Cargo.toml main.rs" | search_text | 50+ matches in 20+ files | ✅ correct | Both files exist |

---

### C. Read (symbols + file outlines)

| Request | Result | Grade | Notes |
|---------|--------|-------|-------|
| outline `src/main.rs` | 22 symbols, accurate line numbers | ✅ correct | L65-77 for startup_plan matches file |
| symbol `startup_plan` (intent=read) | File not found (treated as path) | ❌ wrong | Symbol name used as file path |
| symbol `main` (intent=read) | File not found (treated as path) | ❌ wrong | Same path misrouting |
| read `src/main.rs` | Full file outline | ✅ correct | Path-based works |

**Truncation honesty:** File outline notes `~5101 tokens vs whole-file read` — transparent about truncation.

---

### D. Trace (who calls X)

| Symbol | SymForge refs | Manual check | Recall | Grade |
|--------|---------------|--------------|--------|-------|
| `startup_plan` | 2 refs in 1 file (L233, L460) | 2 call sites visible | 100% | ✅ correct |
| `main` | 459 refs in 83 files | Many `main` functions exist | noisy | ⚠️ partial |

**Finding:** Precise for unique names, noisy for common identifiers.

---

### E. Economics honesty

**All calls:** schema_tokens=45, invoke_tokens=80 (identical every call).

| Call | output_tokens | predicted | error% | Bucket |
|------|---------------|-----------|--------|--------|
| find: "status" | 1576 | ~400 | 294.0% | find |
| find: "main function..." | 1189 | ~800 | 48.6% | find |
| read: src/main.rs | 621 | ~400 | 55.2% | read |
| trace: "main" | 3508 | ~400 | 777.0% | trace |
| trace: "startup_plan" | 138 | ~400 | 65.5% | trace |

**Pattern:** predicted_net=275 for read/trace, 675 for find. predicted=400 or 800 based on route family. No correlation with actual output size.

**Grade: CONFIRMED** — Economics are fixed heuristics.

---

### F. Edit safety

| Step | Result | Grade |
|------|--------|-------|
| Preview mode | [DRY RUN] no disk changes | ✅ correct |
| Apply mode | File modified correctly | ✅ correct |
| Git restore | git status clean | ✅ correct |
| if_match (exact text) | "does not match current symbol body" | ⚠️ over-strict |
| Overwrite manual changes | Edit succeeded, overwrote | ⚠️ partial |

**Grade: PARTIALLY CONFIRMED** — Guard enforced but may use indexed state.

---

### G. Failure modes

| Case | Query | Expected | Observed | Grade |
|------|-------|----------|----------|-------|
| Missing symbol | symbol=NonExistentSymbol | Error | Not tested | ❓ untested |
| Relative path | read: "main.rs" | Error or find | File not found | ✅ correct |
| Full path | read: "src/main.rs" | Find and read | Success | ✅ correct |
| Non-indexed file | read: "Cargo.lock" | Error/fallback | Not tested | ❓ untested |
| Outside repo | read: "../rtk/main.rs" | Reject | Not tested | ❓ untested |

---

## Cross-language notes

All testing performed against Rust project only due to MCP server binding limitation. Unable to verify if behavior differs for TypeScript/JavaScript or Python.

---

## What worked well

1. **File outlines** — Accurate line numbers, honest truncation disclosure
2. **Symbol tracing** — Precise for unique names with file:line references
3. **Edit preview** — No disk writes in dry-run mode
4. **Edit apply** — Correct structural edits with byte counts
5. **Tee snapshots** — Automatic before-write snapshots in `.symforge/tee/`
6. **Impact analysis** — Lists dependent files (126 for startup_plan)
7. **Index stability** — Non-zero, stable counts after multiple queries
8. **Filtering transparency** — Results show filter names (vendor, tests, generated)

## What we could not test / UNVERIFIED

| Item | Reason |
|------|--------|
| Multi-repo testing | MCP server bound to symforge; path param doesn't retarget |
| Cross-language comparison | Unable to switch index to TS/JS or Python repos |
| Full rtk/justice-compass/headroom matrix | MCP configuration limitation |
| Non-indexed file read | Not attempted (Cargo.lock, etc.) |
| Outside-repo path read | Not attempted |
| Exact if_match stale test | Unable to get precise indexed symbol body for controlled test |
| Binary file read | Not attempted |
| Hang/crash resilience | None observed in ~15 calls |

symforge_symforge query="status" intent=find
symforge_symforge path="src/main.rs" intent=read
symforge_symforge symbol="startup_plan" intent=trace
symforge_symforge_edit path="src/main.rs" symbol="startup_plan" apply=false body="..."
symforge_symforge_edit path="src/main.rs" symbol="startup_plan" apply=true if_match="..."

# Git verification:
git status --short  # Verify clean before/after
git checkout -- src/main.rs  # Restore after edits
```

## Conclusion

**SymForge v8.4.0 compact STEL surface is conditionally trustworthy:**

- ✅ **Trust for:** File outlines, symbol tracing (unique names), edit preview/apply, index stability
- ⚠️ **Conditional:** NL routing works but is literal, edit if_match guard enforced but may be over-strict
- ❌ **Do not trust:** Token economics (fixed heuristics), path retargeting (not supported), missing symbol handling

**For LLM usage:** SymForge provides accurate code navigation and editing within its indexed project, but an LLM should not rely on the economics metrics for cost estimation, and should be aware that multi-step queries require manual decomposition.
