# Placeholder Reconciliation Report

**Generated:** 2026-03-30
**Scope:** 111 Placeholders
**Status:** COMPLETE ✓

## Overview

This reconciliation consolidates data from three authoritative sources to create a **single source of truth** for all 111 placeholders in the Mitai Jinkendo system.

### Data Sources

1. **Export Catalog** (`.claude/docs/audit/platzhalter/PLACEHOLDER_CATALOG_EXTENDED.json`)
   - Authoritative placeholder metadata export
   - Contains 111 placeholder definitions with categories, descriptions, time windows, usage data

2. **Audit Reports** (`audit-report-2026-03-29/`)
   - Comprehensive compliance audit against normative requirements
   - Identifies gaps, conflicts, and remediation priorities
   - Classifies placeholders: 8 compliant, 22 partially compliant, 81 non-compliant

3. **Draft Document** (`.claude/docs/concepts/canonical_placeholder_requirements_draft.md`)
   - Normative placeholder specifications (4895 lines)
   - Currently: 0 placeholders documented (draft in progress)

## Critical Issues

### Known Code-Documentation Conflicts

1. **`weight_trend`** - Code uses 28d, docs say 7d/30d
   - Resolution: Update docs to match code (28d)

2. **`activity_summary`** - Code uses 14d, docs say 7d
   - Resolution: Update docs to match code (14d)

3. **`activity_detail`** - Time window unclear in code
   - Resolution: Needs code review to determine actual time window

### High-Usage Placeholders (Breaking Change Risk)

12 placeholders with 4+ uses require careful handling:

| Placeholder | Uses | Compliance |
|-------------|------|------------|
| `name` | 19 | non_compliant |
| `geschlecht` | 14 | non_compliant |
| `height` | 12 | non_compliant |
| `weight_aktuell` | 10 | compliant ✓ |
| `weight_trend` | 10 | compliant ✓ |
| `goal_bf_pct` | 10 | non_compliant |
| `caliper_summary` | 8 | partially_compliant |
| `circ_summary` | 8 | compliant ✓ |
| `goal_weight` | 8 | non_compliant |
| `protein_ziel_low` | 7 | non_compliant |
| `protein_ziel_high` | 7 | non_compliant |
| `activity_detail` | 4 | non_compliant |

### Missing Documentation (P0)

- **49 placeholders** lack category classification
- **49 placeholders** lack descriptions
- **74 placeholders** have unknown time windows

## Recommended Actions

### Immediate (P0) - Week 1

1. **Resolve Known Conflicts** (3 placeholders, 2-4 hours)
   - Update documentation to match code implementation

2. **Classify Time Windows** (74 placeholders, 8-12 hours)
   - Use name-based extraction (`*_7d`, `*_28d` patterns)
   - Extract from code default parameters
   - Manual classification for unclear cases

3. **Add Categories and Descriptions** (49 placeholders, 4-6 hours)
   - Bulk update from audit semantic analysis
   - Use existing audit report classifications

**Total P0 Effort:** 14-20 hours

### Next Sprint (P1) - Weeks 2-3

1. **Add Confidence Logic** (103 placeholders, 12-16 hours)
2. **Document Data Layer Modules** (100 placeholders, 6-8 hours)
3. **Structured Missing-Value Policy** (70 placeholders, 8-10 hours)

**Total P1 Effort:** 26-34 hours

### Later (P2-P3) - Weeks 4-6

1. **Integrate Unused Placeholders** (67 placeholders, 4-6 hours)
2. **Metadata Completeness** (111 placeholders, 10-12 hours)
3. **Production Status** (20-30 core placeholders, 4-6 hours)
4. **Validation Framework** (16-20 hours)

**Total P2-P3 Effort:** 42-56 hours

## Best-Practice Models

### Compliant Placeholders (8 total)

These serve as best-practice models for all others:

**Nutrition Averages (4):**
- `protein_avg`, `kcal_avg`, `fat_avg`, `carb_avg`
- Pattern: 30d time window, calculate_confidence, nutrition_metrics.py

**Body Metrics (3):**
- `weight_aktuell` (latest pattern, body_metrics.py)
- `weight_trend` (28d trend, calculate_confidence) *has conflict*
- `circ_summary` (mixed time window, best-of-each pattern)

**Profile (1):**
- `age` (snapshot, no confidence needed)

## Architecture Verification

- **71 placeholders (63%)** exist in code with sound architecture
- **40 placeholders (36%)** not implemented, need build
- **0 placeholders** with fundamental architecture issues

All implemented placeholders have valid resolvers and data sources.

## Success Metrics

### After P0 Remediation (Week 1)
- 0 unknown time windows ✓
- 0 unknown categories ✓
- 0 code-documentation conflicts ✓

### After P1 Remediation (Weeks 2-3)
- 70%+ placeholders with confidence logic
- 100% placeholders with structured missing-value policies
- 100% placeholders with documented data layers

### After P2-P3 Remediation (Weeks 4-6)
- 50-60% placeholder usage rate
- 60%+ placeholders with metadata completeness >60
- 20-30 production-ready placeholders

## Conclusion

The reconciliation process successfully analyzed all 111 placeholders and created a comprehensive single source of truth. While only 7% are currently fully compliant with normative requirements, the systematic gaps are primarily **documentation-related rather than functional**.

All 111 placeholders are:
- ✅ Properly inventoried
- ✅ Categorized by compliance level
- ✅ Prioritized for remediation
- ✅ Mapped to implementation plan

With a structured 4-6 week remediation plan (82-110 hours), the system can reach **>60% normative conformity** and establish a sustainable maintenance process.

## Next Steps

1. **Review** this reconciliation with product/tech leads
2. **Prioritize** P0 items for Week 1 sprint
3. **Execute** systematic remediation following implementation waves
4. **Track** progress against success metrics
5. **Iterate** based on findings and feedback
