+# Continuita Storico -> Day-0
+
+Data aggiornamento: 11-03-2026
+
+## Perche questo file
+
+Garantire che nulla del lavoro storico venga perso nel passaggio a Day-0, senza sporcare il nuovo Git.
+
+## Principio operativo
+
+1. Codice e release: solo repository Day-0 (`netgescon-day0`).
+2. Materiale storico operativo/personale: mirror locale in `_legacy-vault` (git ignored).
+3. Verita di distribuzione: branch `main` di `michele/netgescon-day0`.
+
+## Come sincronizzare lo storico nel Day-0
+
+```bash
+cd /home/michele/netgescon/netgescon-day0
+bash scripts/ops/netgescon-day0-legacy-sync.sh
+```
+
+Output atteso:
+
+- cartella: `/home/michele/netgescon/netgescon-day0/_legacy-vault`
+- indice: `_legacy-vault/INDEX-LEGACY-VAULT.txt`
+
+## Cosa viene importato nel vault
+
+1. `Miki-Bug-workspace/`
+2. `docs/ai/`
+3. `docs/00-IMPORT/`
+4. `docs/incidents/`
+5. `incoming/`
+6. `CREDENZIALI_UI_LOCALI_20260311_121500.md` (se presente)
+
+## Come riprendere in una nuova sessione agent
+
+1. Chiedi all'agent di leggere:
+   - `docs/ai/restart/START-HERE-NETGESCON-DAY0.md`
+   - `docs/ai/restart/HANDOFF_AGENT_OPERATIVO_20260311.md`
+   - `docs/ai/restart/CONTINUITA-STORICO-DAY0.md`
+2. Se serve contesto storico extra, usare `_legacy-vault/`.
+3. Le modifiche da rilasciare devono restare nel tree principale Day-0, non nel vault.
+
+## Checklist anti-perdita
+
+- [ ] Backup locale presente
+- [ ] Backup esterno presente
+- [ ] `git status` pulito in Day-0 prima di release
+- [ ] Sync vault eseguita almeno una volta al giorno durante migrazione
+- [ ] Handoff aggiornato in `docs/ai/restart/`
