# Aktivität: Layer-2a-Platzhalter — Audit Schritt 1 (Issue #53)
|
|||
|
|
|
|||
|
|
**Stand:** 2026-04-16
|
|||
|
|
**Bezug:** [Issue #53 — Multi-Layer Architecture](../../../docs/issues/issue-53-phase-0c-multi-layer-architecture.md): Layer 1 = strukturierte Daten, Layer 2a = KI-Formatierung (keine parallele Domänen-Logik im Resolver).
|
|||
|
|
|
|||
|
|
**Ziel dieses Dokuments:** Jeder Aktivitäts-Platzhalter hat genau eine **Layer‑1‑Quelle** (`data_layer/activity_metrics.py`); `placeholder_resolver.py` formatiert oder serialisiert nur noch.
|
|||

## 1. Ergebnisübersicht
|
|||
|
|
|
|||
|
|
| Kategorie | Anzahl | Resolver-SQL für Aktivität? |
|
|||
|
|
|-----------|--------|------------------------------|
|
|||
|
|
| Gebündelt in `PLACEHOLDER_MAP` (Training/Aktivität) | 20 | **Nein** |
|
|||
|
|
| Abweichungen / offene Punkte | 0 | — |
|
|||
|
|
|
|||
|
|
**Hinweis:** `{{rest_days_count}}` steht in der Karte unter „Schlaf & Erholung“ und nutzt `recovery_metrics.get_rest_days_data` — nicht in dieser Tabelle.

## 3. Schichten-Disziplin (Checkliste)
|
|||
|
|
|
|||
|
|
- [x] Kein `SELECT` auf `activity_log` / `activity_session_metrics` in den **Layer‑2a**-Funktionen oben — nur Aufrufe in Layer 1 bzw. `_safe_*`-Wrapper.
|
|||
|
|
- [x] `get_activity_detail` / `get_training_sessions_recent_json` liefern EAV nur über **bereits gemergte** `session_metrics` (Merge-Kanon: `activity_log` vor EAV).
|
|||
|
|
- [x] Registry-Metadaten: `data_layer_module` / `data_layer_function` pro Key in `placeholder_registrations/activity_metrics.py` und `activity_session_insights.py`.
|
|||
|
|
- [x] Korrektur Registry: `activity_summary.resolver_function` = `get_activity_summary` (war veraltet: `_format_activity_summary`).
|
|||

## 4. Nächste Schritte (Roadmap)
|
|||
|
|
|
|||
|
|
2. ~~**Registry-Texte:** `semantic_contract` / `known_limitations` für dynamische `session_metrics` (tcp/ttp) und Merge-Kanon — **erledigt** (`activity_detail`, `training_sessions_recent_json`); dazu **`trainingstyp_verteilung`**-Metadaten von veraltetem „JSON/Resolver-SQL“ auf Ist (**Layer 1 + Top-3-Text**) korrigiert.~~
|
|||
|
|
3. **History / Layer 2b:** EAV-Zeitreihen nicht über Platzhalter, sondern dedizierte Layer‑1-/Chart-Pfade.
|
|||
|
|
4. **Optional:** Gitea-Issue „Activity Layer 2a“ bei Änderungen an `activity_metrics` pflegen.
