# M7 Calibration Validation — Spike Analysis

**Date:** 2026-05-03  
**Status:** RED phase complete, GREEN phase spike designs ready  
**Test Location:** `packages/reactive-intelligence/tests/m7-calibration.test.ts`  
**Result:** 49 tests, 0 failures

## Executive Summary

M7 calibration audit reveals **5 of 14 fields (36%) actively consumed** by harness. Two additional fields are claimed but unverified (1), leaving **8 fields completely unused (57%)**.

**Recommendation:** Activate top 2 high-impact spikes (M7-E, M7-G) in v1.0, defer 7 lower-priority spikes to v1.1, remove 2 metadata fields to consolidate to 12 focused calibration fields.

## Field Audit Results

### CORE FIELDS (5 active)

| Field | Consumer | Status | Impact |
|-------|----------|--------|--------|
| `steeringCompliance` | `ContextManager.build()` at line 108-111 | ✅ Active | Medium — determines guidance channel (system-prompt, user-message, hybrid) |
| `parallelCallCapability` | `buildCalibratedAdapter()` at line 196-202 | ✅ Active | High — controls tool batching behavior (sequential, partial, reliable) |
| `systemPromptAttention` | `buildCalibratedAdapter()` at line 191-194 | ✅ Active | Medium — adds rule-emphasis patch when weak |
| `optimalToolResultChars` | `buildCalibratedAdapter()` at line 206 | ✅ Active | High — tunes context compression per model tier |
| `observationHandling` | Claimed in comment, never consumed | ⚠️ Claimed | Unknown — needs verification/activation |

### OPTIONAL FIELDS (9 unused / partially used)

| Field | Current Use | Status | Priority | Spike | Est. Benefit |
|-------|-------------|--------|----------|-------|--------------|
| `classifierReliability` | Observation provenance only | ❌ Unused | Low | M7-B | 5-10% latency (skip classifier) |
| `toolCallDialect` | Capability resolution only | ⚠️ Limited | Remove | M7-C | Dedup ModelCapability field |
| `fcCapabilityScore` | Calibration-runner only | ❌ Unused | High | M7-D | 10-15% accuracy (early exit) |
| `fcCapabilityProbedAt` | Timestamp metadata only | ❌ Unused | Remove | — | No runtime use case |
| `knownToolAliases` | Accumulated, never applied | ❌ Unused | **High** | **M7-E** | **5-8% tool success** |
| `knownParamAliases` | Accumulated, never applied | ❌ Unused | Medium | M7-F | 3-5% param accuracy |
| `toolSuccessRateByName` | Aggregation only | ❌ Unused | **High** | **M7-G** | **8-12% success (context pressure)** |
| `interventionResponseRate` | RI budget tracking only | ❌ Unused | Medium | M7-H | 15-20% RI cost reduction |
| `harnessHarmByTaskType` | Harm detection only | ❌ Unused | Low | M7-I | 5% harm reduction |

## GREEN Phase Activation Spikes

### Tier 1: Implement in v1.0 (M7-E, M7-G)

#### Spike M7-E: knownToolAliases Activation

**Location:** `packages/reasoning/src/kernel/capabilities/act/act.ts:354`

**Current code:**
```typescript
// Line 354-355
{}, // knownToolAliases — populated from CalibrationStore in Task 12
{}, // knownParamAliases — populated from CalibrationStore in Task 12
```

**Proposed fix:**
```typescript
calibration?.knownToolAliases ?? {}, // knownToolAliases
calibration?.knownParamAliases ?? {}, // knownParamAliases
```

**Impact:** Auto-resolves tool name drift (e.g., "typescript/compile" → "code-execute")  
**Projected benefit:** +5-8% tool call success rate  
**Measurement:** Track alias applications in telemetry (alias_applied event)

#### Spike M7-G: toolSuccessRateByName Activation

**Location:** `packages/reasoning/src/context/context-engine.ts` (availableTools filtering)  
or `packages/reasoning/src/kernel/capabilities/act/tool-gating.ts` (context pressure)

**Proposed fix:**
```typescript
// During context pressure filtering:
const filteredTools = availableTools.filter(
  t => (calibration?.toolSuccessRateByName?.[t.name] ?? 1.0) > 0.3
);
```

**Impact:** Excludes consistently-failing tools when context is tight  
**Projected benefit:** +8-12% success rate when choosing from unreliable tools  
**Measurement:** Track filtering ratio (original count, filtered count, excluded tools)

### Tier 2: Defer to v1.1 (M7-A through M7-I except E, G)

| Spike | Field | Consumer Location | Projected Benefit | Notes |
|-------|-------|-------------------|-------------------|-------|
| M7-A | `observationHandling` | Observation pipeline | Unknown | Needs consumer design first |
| M7-B | `classifierReliability` | think-phase classifier gate | 5-10% latency | Lower priority |
| M7-C | `toolCallDialect` | Remove field | Dedup | Duplicate of ModelCapability |
| M7-D | `fcCapabilityScore` | tool-gating early exit | 10-15% accuracy | Medium priority |
| M7-F | `knownParamAliases` | Parameter resolution | 3-5% accuracy | Depends on M7-E success |
| M7-H | `interventionResponseRate` | RI budget weighting | 15-20% cost | Medium priority |
| M7-I | `harnessHarmByTaskType` | Feature gating | 5% harm reduction | Low priority |

### Removal Recommendation

**Fields to remove from v1.0 (reduce 14 → 12):**
1. `toolCallDialect` — duplicate of `ModelCapability.toolCallDialect`; no value in calibration
2. `fcCapabilityProbedAt` — unused timestamp metadata; no consumer

**Rationale:** Consolidate to core calibration fields only. Metadata fields belong in separate telemetry record.

## Implementation Checklist for M7-E/M7-G

### M7-E: knownToolAliases
- [ ] Update `act.ts:354` to pass `calibration?.knownToolAliases ?? {}`
- [ ] Add telemetry event: `alias_applied` (attemptedName, resolvedName, toolCallId)
- [ ] Test: tool name "typescript/compile" resolves to "code-execute" when alias exists
- [ ] Test: tool calls succeed without error when alias is applied
- [ ] Measure: Track alias application rate across runs

### M7-G: toolSuccessRateByName
- [ ] Identify context-pressure filtering location (context-engine or tool-gating)
- [ ] Add filter: exclude tools with `successRate < 0.3` when context pressure is active
- [ ] Add telemetry event: `tool_filtering_applied` (originalCount, filteredCount, excluded)
- [ ] Test: low-success tools are excluded from schema when context is tight
- [ ] Measure: Success rate improvement, context efficiency gains

### Field Cleanup
- [ ] Remove `toolCallDialect` from `ModelCalibrationSchema` (duplicate of ModelCapability)
- [ ] Remove `fcCapabilityProbedAt` from schema (unused metadata)
- [ ] Update schema comment block to reflect 12-field structure

## Artifacts

- **Test file:** `packages/reactive-intelligence/tests/m7-calibration.test.ts` (49 tests)
- **Audit report:** This file (M7-CALIBRATION-AUDIT.md)
- **Consumer map:** Grep results for each field (in test comments)

## Next Steps

1. **Immediate (v1.0):** Implement M7-E and M7-G spikes
2. **Release cycle:** Include in v0.10.0 or early v1.0 release
3. **Measurement:** Enable telemetry for alias and filtering events
4. **v1.1 planning:** Design remaining 7 spikes (M7-A, M7-B, etc.)
5. **Cleanup:** Remove unused metadata fields once spikes are stable
