michele cd7a7ca3a6 Join PE-BOM-011 pins by name, not pin_count (2.63.2).
USB-C A5/B5 are contacts, not EP. Datasheet pintable, KiCad
.kicad_mod, and embedded PCB pads join by pin identity. Missing
pintable skips; scalar pin_count is never an ERROR authority.

# Albero delle analisi Periscope
Versione codice **2.63.1** (`periscope/src/frontend/content/changelog.md`). Letto in `/Users/michelebigi/Development/periscope`. Costituzione senza eccezioni: via ≠ pad ≠ traccia ≠ zona; niente I/Z/mm inventati; skip se manca evidenza. **Non è DRC KiCad.** DRC = KiCad. Questo documento mappa lanalisi, non implementa.
I test pytest stanno in `tests/datasheet/`, `tests/library/`, `tests/schematic/`, `tests/pcb/`, `tests/af_ai/` (stessi file di 2.62.1, cartelle di mestiere). I path `tests/test_*.py` sotto i nodi restano i nomi file.
Due pipeline più una porta libreria (non è un esame):
0. **Libreria**`POST /api/library/datasheets` registra un componente da PDF senza `MODE=run`/`MODE=pcb`.
1. **Schematico / review AI**`MODE=run`, `services/pipeline.py``validate_design_async` (`validation.py`): estrazione datasheet, check deterministici, review IC DeepSeek.
2. **Esame PCB**`MODE=pcb`, `services/pcb_pipeline.py``run_pcb_checks` (`pcb_checks.py`, lista 2.62.1 **invariata**) + sezione additiva AF Board+AI (`af_ai_hf.py`) + review AI PCB (`pcb_review.py` / `pcb_validation.py`). Non auto-place.
I certifier USB-C / Ethernet / PoE girano su **entrambe** le pipeline (grafo, non geometria). DDR / CPU / FPGA / USB-PD sono la stessa qualità di finding ma partono da `run_pcb_checks` (grafo). Niente pezzo sul grafo → silenzio, non N/A.
Nodi analisi: **108** (99 PE-* + 1 LED senza `rule_id` + 8 processo estrazione/AI). Test pytest citati sotto i nodi: nomi reali da `tests/`.

## 1. Schematico / review AI (`MODE=run`)
Orchestrazione: `pipeline.py` stadi `bom_parse``ic_extraction``simple_extraction``passive_extraction``graph_build``validation`. Check deterministici: `_run_deterministic_checks` in `validation.py`. Finding ID schema `PS-{ref}-{nnn}` (non `PCB-`).
### 1.1 Ingest (prerequisito, non analisi)
Parser e grafo non emettono PE-*. Skip MPN: `ic_mpn_skip_reason` (silenzio onesto, niente MPN inventato).
- Test parser/grafo: `tests/test_bom_parser.py` (`test_parse_bom_uses_value_for_ic_when_mpn_column_empty`, `test_parse_bom_keeps_pnm_and_datasheet_url`); `tests/test_hubaudio_bom.py` (tutti e 4); `tests/test_netlist_parser.py` (tutti e 3); `tests/test_edif_parser.py` (14); `tests/test_kicad_parser.py` (17); `tests/test_kicad_project.py` (19); `tests/test_netlist_bundle.py` (9); `tests/test_functional_groups.py` (8).
- Test overlay parser: `tests/test_periscope_parsers_rewrite.py`, `tests/test_periscope_graph_rewrite.py`, `tests/test_periscope_models_rewrite.py`.
### 1.2 Estrazione datasheet (processo)
Skip se manca PDF o lo skill non ha numero. Libreria `library/extracted` condivisa schema+PCB. PCB review non rilegge il PDF (`pdf_path=None`).
#### `extract-pintable` — skill `skills/extract-pintable/`
Modulo: `services/datasheet_extract.py` + `llm/local_skill.py`. Analizza: pin table, package, taxonomy IC.

## 2. Esame PCB (`MODE=pcb`)
Stadi: `ensure_graph``parse_pcb``classify``inventory`**`run_pcb_checks`** → `ai_review``pcb_report.json`. ID finding `PCB-{ref}-{001}`. Mutex vs analisi schema e vs placement. Inventario net (`pcb_inventory.py`) è numeri, non finding.
KiCad DRC **non** è un nodo Periscope. `tests/test_pcb_software_bugs.py` `test_drc_unconnected_items_count` e `test_hubaudio_pcb_lay004_vs_drc_order_of_magnitude` servono solo a **non** copiare il DRC.
