+# Backup Sovereign
+
+High-risk Tier 1 skill for creating encrypted, verifiable backups. All backups include BLAKE3 proof receipts and require a mandatory restore drill to verify recoverability.
+
+## Quick Start
+
+```bash
+# Set required parameters
+export BACKUP_SOURCES="$HOME/infrastructure,$HOME/.claude/skills"
+export AGE_RECIPIENT_FILE="$HOME/.config/age/recipients.txt"
+export AGE_IDENTITY_FILE="$HOME/.config/age/identity.txt"
+
+# Optional: customize
+export NODE_NAME="node-a"
+export BACKUP_LABEL="daily"
+
+# Run preflight
+./scripts/00_preflight.sh
+
+# Plan phases (safe to run, shows what WILL happen)
+./scripts/10_backup_plan.sh
+./scripts/20_encrypt_plan.sh
+
+# Apply phases (REQUIRES DRY_RUN=0 and confirmation)
+export DRY_RUN=0
+./scripts/11_backup_apply.sh    # Type confirmation phrase
+./scripts/21_encrypt_apply.sh   # Type confirmation phrase
+
+# Generate proof receipts
+./scripts/30_generate_proof.sh
+
+# Verify artifacts
+./scripts/40_verify_backup.sh
+
+# MANDATORY: Restore drill
+./scripts/50_restore_drill.sh   # Type confirmation phrase
+
+# Status and report
+./scripts/90_verify.sh
+./scripts/99_report.sh
+```
+
+## Workflow
+
+### Phase 0: Preflight (00)
+Check dependencies: tar, gzip, age, b3sum.
+Verify BACKUP_SOURCES paths exist.
+Check available disk space.
+
+### Phase 1: Backup (10-11)
+**Two-phase operation with DRY_RUN gate.**
+
+Plan phase shows:
+- Source paths to archive
+- Exclude patterns
+- Output directory and run ID
+- Estimated archive size
+
+Apply phase executes:
+- Creates tar.gz archive
+- Generates manifest.json with BLAKE3 hashes
+- Records excludes.txt
+
+### Phase 2: Encrypt (20-21)
+**Two-phase operation with DRY_RUN gate.**
+
+Plan phase shows:
+- Encryption method (age)
+- Recipient file location
+- Output file path
+
+Apply phase executes:
+- Encrypts archive with age
+- Creates archive.tar.gz.age
+
+### Phase 3: Proof (30)
+Generate cryptographic proof receipts:
+- BLAKE3 hash of manifest.json
+- BLAKE3 hash of encrypted archive
+- ROOT.txt (composite hash for anchoring)
+- PROOF.json (metadata receipt)
+
+### Phase 4: Verify (40)
+Verify all artifacts exist and ROOT.txt is valid.
+
+### Phase 5: Restore Drill (50) **MANDATORY**
+**DRY_RUN gate + CONFIRM_PHRASE**
+
+This phase is required to validate backup recoverability:
+- Decrypts archive to temp directory
+- Extracts and verifies file count
+- Records restore location
+
+### Phase 6: Status + Report (90-99)
+Generate JSON status matrix and markdown audit report.
+
+## Inputs
+
+| Parameter | Required | Default | Description |
+|-----------|----------|---------|-------------|
+| BACKUP_SOURCES | Yes | - | Comma-separated paths to backup |
+| AGE_RECIPIENT_FILE | Yes | - | File with age public key(s) |
+| AGE_IDENTITY_FILE | Yes | - | File with age private key (for restore) |
+| NODE_NAME | No | node-a | Node identifier |
+| BACKUP_LABEL | No | manual | Label for this backup run |
+| BACKUP_EXCLUDES | No | .git,node_modules,target,dist,outputs | Exclude patterns |
+| OUTPUT_DIR | No | outputs | Output directory |
+| DRY_RUN | No | 1 | Set to 0 to enable apply scripts |
+| REQUIRE_CONFIRM | No | 1 | Require confirmation phrase |
+| CONFIRM_PHRASE | No | I UNDERSTAND THIS WILL CREATE AND ENCRYPT BACKUPS | Safety phrase |
+
+## Outputs
+
+| File | Description |
+|------|-------------|
+| `outputs/runs/<run_id>/archive.tar.gz` | Unencrypted archive |
+| `outputs/runs/<run_id>/archive.tar.gz.age` | Encrypted archive |
+| `outputs/runs/<run_id>/manifest.json` | File list + sizes + BLAKE3 hashes |
+| `outputs/runs/<run_id>/ROOT.txt` | BLAKE3 root (for anchoring) |
+| `outputs/runs/<run_id>/PROOF.json` | Metadata receipt |
+| `outputs/runs/<run_id>/excludes.txt` | Exclude patterns used |
+| `outputs/status_matrix.json` | Verification results |
+| `outputs/audit_report.md` | Human-readable audit trail |
+
+## Safety Guarantees
+
+1. **DRY_RUN=1 by default** - Apply scripts refuse to run without explicit DRY_RUN=0
+2. **CONFIRM_PHRASE required** - Must type exact phrase to proceed
+3. **Mandatory restore drill** - Untested backups are not trusted
+4. **BLAKE3 hashes** - Cryptographic integrity verification
+5. **ROOT.txt for anchoring** - Can be submitted to merkle-forest/rfc3161-anchor
+6. **Per-run isolation** - Each backup is immutable once created
+7. **All scripts idempotent** - Safe to run multiple times
+
+## age Key Setup
+
+If you don't have age keys yet:
+
+```bash
+# Generate identity (private key)
+age-keygen -o ~/.config/age/identity.txt
+
+# Extract public key to recipients file
+age-keygen -y ~/.config/age/identity.txt > ~/.config/age/recipients.txt
+```
+
+## EU Compliance
+
+| Aspect | Value |
+|--------|-------|
+| Data Residency | EU (Ireland - Dublin) |
+| GDPR Applicable | Yes (depends on backup content) |
+| Jurisdiction | Irish Law |
+| Encryption at Rest | Yes (age) |

+
+## Next Steps
+
+After completing backup-sovereign:
+1. Store encrypted bundle off-node (secondary disk / object store)
+2. Test restore on a different machine (recommended)
+3. Optionally anchor ROOT.txt with rfc3161-anchor skill
+4. Proceed to **disaster-recovery** skill

+# Recovery Notes
+
+## Overview
+
+This document describes recovery procedures for backup-sovereign backups.
+
+## Prerequisites
+
+- `age` installed (for decryption)
+- Access to AGE_IDENTITY_FILE (private key)
+- Sufficient disk space for extraction
+
+## Standard Recovery
+
+### 1. Locate Backup
+
+Find your encrypted backup:
+```bash
+ls ~/.claude/skills/backup-sovereign/outputs/runs/
+```
+
+### 2. Decrypt Archive
+
+```bash
+# Set identity file
+export AGE_IDENTITY_FILE="$HOME/.config/age/identity.txt"
+
+# Decrypt
+age -d -i "$AGE_IDENTITY_FILE" \
+    -o archive.tar.gz \
+    archive.tar.gz.age
+```
+
+### 3. Extract
+
+```bash
+# Extract to current directory
+tar -xzf archive.tar.gz
+
+# Or extract to specific location
+tar -xzf archive.tar.gz -C /path/to/restore/
+```
+
+### 4. Verify Integrity
+
+Compare BLAKE3 hash with manifest:
+```bash
+# Compute hash of archive
+b3sum archive.tar.gz
+
+# Compare with value in manifest.json
+cat manifest.json | grep blake3
+```
+
+## Disaster Recovery
+
+If you've lost access to your primary system:
+
+1. **Obtain encrypted backup** from off-site storage
+2. **Obtain identity file** from secure backup location
+3. Follow standard recovery steps above
+
+## Verify ROOT
+
+To verify the backup hasn't been tampered with:
+
+```bash
+# Compute manifest hash
+MANIFEST_B3=$(b3sum manifest.json | awk '{print $1}')
+
+# Compute encrypted archive hash
+ENC_B3=$(b3sum archive.tar.gz.age | awk '{print $1}')
+
+# Compute ROOT
+echo -n "${MANIFEST_B3}${ENC_B3}" | b3sum
+
+# Compare with ROOT.txt
+cat ROOT.txt
+```
+
+## Key Management
+
+### age Keys
+
+- **Identity file** (private key): Keep secure, backed up separately
+- **Recipients file** (public key): Can be shared, used for encryption
+
+### Generate New Keys
+
+If you need new keys:
+```bash
+# Generate identity
+age-keygen -o ~/.config/age/identity.txt
+
+# Extract public key
+age-keygen -y ~/.config/age/identity.txt > ~/.config/age/recipients.txt
+```
+
+### Key Rotation
+
+1. Generate new keypair
+2. Add new public key to recipients file
+3. Keep old identity file for decrypting old backups
+4. New backups will be encrypted to all recipients
+
+## Troubleshooting
+
+### "age: error: no identity matched any of the recipients"
+
+- Wrong identity file
+- Backup was encrypted with different key
+- Solution: Use correct identity file
+
+### "tar: Error opening archive"
+
+- Corrupted archive
+- Incomplete download
+- Solution: Verify BLAKE3 hash, re-download if needed
+
+### "b3sum: command not found"
+
+- Install b3sum: `cargo install b3sum` or use package manager
+- Alternative: Use `blake3` CLI if available
+
+## Security Considerations
+
+1. **Never store identity file with encrypted backups**
+2. **Use passphrase-protected identity** for extra security
+3. **Test restore drill regularly** - backups that haven't been tested aren't backups
+4. **Store backups off-site** - same location defeats the purpose

+  Anchor a Merkle root (root_hex) to Bitcoin testnet or mainnet using OP_RETURN via bitcoin-cli.
+  Emits PROOF.json + tx metadata with plan/apply/rollback and verification.
+  Consumes merkle-forest ROOT.txt (or explicit ROOT_HEX). Triggers: 'btc anchor',
+  'anchor root on bitcoin', 'op_return', 'taproot proof', 'bitcoin-cli'.
+version: 1.0.0
+---
+
+# BTC Anchor (OP_RETURN via bitcoin-cli)
+
+This skill anchors a **root_hex** on Bitcoin by creating a transaction
+with an **OP_RETURN** output containing the root bytes.
+
+## Requirements
+- `bitcoin-cli` connected to a synced node (mainnet/testnet/signet)
+- Wallet loaded + funded (UTXOs)
+- Network parameters set (v1 uses `bitcoin-cli -testnet` / `-signet` flags)
+
+## Quick Start
+
+```bash
+cd ~/.claude/skills/btc-anchor
+
+export ROOT_FILE="$HOME/.claude/skills/merkle-forest/outputs/runs/<run>/ROOT.txt"
+export BTC_NETWORK="testnet"          # mainnet|testnet|signet
+export BTC_FEE_RATE="5"              # sat/vB (rough)
+export OP_RETURN_PREFIX="VM"         # 2-byte ascii prefix
+
+./scripts/00_preflight.sh
+./scripts/10_plan.sh
+
+export DRY_RUN=0
+./scripts/11_apply.sh
+
+./scripts/90_verify.sh
+./scripts/99_report.sh
+```
+
+## Inputs
+
+| Parameter | Required | Default | Description |
+|---|---:|---|---|
+| ROOT_FILE | No | (empty) | ROOT.txt path |
+| ROOT_HEX | No | (empty) | Explicit root hex (overrides ROOT_FILE) |
+| BTC_NETWORK | No | testnet | mainnet/testnet/signet |
+| BTC_FEE_RATE | No | 5 | sat/vB (passed to walletcreatefundedpsbt) |
+| OP_RETURN_PREFIX | No | VM | ASCII prefix (helps identify payloads) |
+| DRY_RUN | No | 1 | Apply refuses unless DRY_RUN=0 |
+| REQUIRE_CONFIRM | No | 1 | Require confirmation phrase |
+| CONFIRM_PHRASE | No | I UNDERSTAND THIS WILL BROADCAST A BITCOIN TX | Safety phrase |
+
+## Outputs
+`outputs/runs/<label>_<timestamp>/`
+- root_hex.txt
+- op_return_hex.txt
+- txid.txt
+- rawtx.hex
+- PROOF.json
+- status_matrix.json
+- audit_report.md
+
+## Notes
+- Payload format: `<prefix-as-hex><root-bytes>` truncated to fit OP_RETURN.
+- v1 uses OP_RETURN and the node wallet RPCs: create raw tx → fund → sign → send.

+
+## Method
+v1 anchors via OP_RETURN using the node wallet RPC flow:
+- walletcreatefundedpsbt
+- walletprocesspsbt
+- finalizepsbt
+- sendrawtransaction
+
+## Payload
+ASCII prefix (default "VM") + root bytes, truncated to standard OP_RETURN limits.
+
+## Ops
+Prefer testnet/signet during development, then mainnet with tight fee control.

+  Plan/apply/rollback for Cloudflare Tunnel lifecycle (create, configure,
+  route DNS, run as service). Includes DRY_RUN safety gates, status matrix,
+  and audit report. Triggers: 'cloudflare tunnel', 'create tunnel', 'tunnel plan',
+  'tunnel rollback', 'cloudflared config', 'dns route'.
+version: 1.0.0
+---
+
+# Cloudflare Tunnel Manager
+
+Tier 1 skill for managing **Cloudflare Tunnels** safely:
+- **Plan → Apply** workflow (two-phase)
+- **Rollback** scripts for DNS route, service, and tunnel delete
+- Verification + audit report
+
+Designed for sovereign Node A style setups where you terminate TLS at Cloudflare
+and route traffic to a local service over a tunnel.
+
+## Quick Start
+
+```bash
+cd ~/.claude/skills/cloudflare-tunnel-manager
+
+# Required
+export CF_API_TOKEN="..."           # Cloudflare API token
+export CF_ACCOUNT_ID="..."          # Cloudflare account ID
+
+# Tunnel identity
+export TUNNEL_NAME="node-a-tunnel"
+export ZONE_NAME="example.com"      # domain in Cloudflare
+export HOSTNAME="node-a.example.com"
+
+# Local origin (what tunnel forwards to)
+export LOCAL_SERVICE="http://127.0.0.1:9110"
+
+# Safety
+export DRY_RUN=1
+export REQUIRE_CONFIRM=1
+export CONFIRM_PHRASE="I UNDERSTAND THIS CAN CHANGE DNS AND TUNNEL ROUTES"
+
+./scripts/00_preflight.sh
+./scripts/10_tunnel_plan.sh
+./scripts/20_dns_plan.sh
+./scripts/30_service_plan.sh
+
+export DRY_RUN=0
+./scripts/11_tunnel_apply.sh
+./scripts/21_dns_apply.sh
+./scripts/31_service_apply.sh
+
+./scripts/90_verify.sh
+./scripts/99_report.sh
+```
+
+## Inputs
+
+| Parameter | Required | Default | Description |
+|---|---:|---|---|
+| CF_API_TOKEN | Yes | (none) | Cloudflare API token with Tunnel + DNS permissions |
+| CF_ACCOUNT_ID | Yes | (none) | Cloudflare account ID |
+| TUNNEL_NAME | Yes | (none) | Tunnel name |
+| ZONE_NAME | Yes | (none) | Zone/domain in Cloudflare (e.g., example.com) |
+| HOSTNAME | Yes | (none) | DNS hostname to route (e.g., node-a.example.com) |
+| LOCAL_SERVICE | Yes | (none) | Local origin URL (e.g., http://127.0.0.1:9110) |
+| CONFIG_DIR | No | outputs/config | Where generated config lives |
+| SERVICE_NAME | No | cloudflared-tunnel | systemd unit name |
+| DRY_RUN | No | 1 | Apply scripts refuse unless DRY_RUN=0 |
+| REQUIRE_CONFIRM | No | 1 | Require confirmation phrase |
+| CONFIRM_PHRASE | No | I UNDERSTAND THIS CAN CHANGE DNS AND TUNNEL ROUTES | Safety phrase |
+
+## Outputs
+
+- `outputs/config/config.yml` (generated cloudflared config)
+- `outputs/config/tunnel.json` (tunnel metadata snapshot)
+- `outputs/status_matrix.json`
+- `outputs/audit_report.md`
+
+## Safety Guarantees
+
+1. Default **DRY_RUN=1**
+2. Confirmation phrase required for apply and rollback
+3. Plan scripts print exact commands and expected changes
+4. Rollbacks available:
+   - DNS route removal
+   - systemd service stop/disable
+   - tunnel delete (optional)
+
+## Notes
+
+- This skill uses `cloudflared` CLI.
+- You can run the tunnel without systemd (manual) if desired.
+
+## EU Compliance
+
+| Aspect | Value |
+|---|---|
+| Data Residency | EU (Ireland - Dublin) |
+| Jurisdiction | Irish Law |
+| Transport | Encrypted tunnel (Cloudflare) |
+| Logs | Local status + reports only |

+# Cloudflare Tunnel Notes
+
+## API Token Permissions (recommended)
+- Account: Cloudflare Tunnel (read/edit)
+- Zone: DNS (read/edit)
+
+## Credentials
+`cloudflared tunnel create` generates a credentials JSON file under:
+`~/.cloudflared/<tunnel-id>.json`
+
+This skill's generated `config.yml` references that file directly.
+
+## Ingress
+Default pattern:
+- Hostname -> LOCAL_SERVICE
+- Fallback -> 404
+
+## Rollback Order
+1. Stop/disable service
+2. Remove DNS route
+3. Delete tunnel (optional)

+  Bootstrap a sovereign container registry (OCI/Docker) with plan/apply/rollback,
+  signature verification hooks, backups, and audit report. Designed to pair with

+  'oci registry', 'self-host registry', 'registry plan'.
+version: 1.0.0

+
+# Container Registry (Sovereign)
+
+Tier 2 skill: establish a **self-hosted OCI registry** you control.
+
+This skill deploys a Docker Registry v2 (with optional UI) using
+plan/apply gates and produces verifiable artifacts.
+
+## Quick Start
+
+```bash
+cd ~/.claude/skills/container-registry
+
+export MODE="docker"                 # docker only in v1
+export NODE_NAME="node-b"
+
+# Network
+export REGISTRY_PORT=5000
+export DOMAIN="registry.example.com"   # optional (for reverse proxy)
+
+# Storage
+export DATA_DIR="$HOME/registry"
+export AUTH_DIR="$HOME/registry/auth"
+
+# Auth (basic auth for v1)
+export REGISTRY_USER="sovereign"
+
+# Safety
+export DRY_RUN=1
+export REQUIRE_CONFIRM=1
+export CONFIRM_PHRASE="I UNDERSTAND THIS WILL DEPLOY A CONTAINER REGISTRY"
+
+./scripts/00_preflight.sh
+./scripts/10_plan.sh
+
+export DRY_RUN=0
+./scripts/11_apply.sh
+
+./scripts/90_verify.sh
+./scripts/99_report.sh
+```
+
+## Inputs
+
+| Parameter | Required | Default | Description |
+|---|---:|---|---|
+| MODE | Yes | docker | docker |
+| REGISTRY_PORT | No | 5000 | Registry port |
+| DOMAIN | No | (empty) | Hostname if proxied |
+| DATA_DIR | No | ~/registry | Registry storage |
+| AUTH_DIR | No | ~/registry/auth | htpasswd storage |
+| REGISTRY_USER | Yes | (none) | Registry username |
+| DRY_RUN | No | 1 | Apply refuses unless DRY_RUN=0 |
+| REQUIRE_CONFIRM | No | 1 | Require confirmation phrase |
+| CONFIRM_PHRASE | No | I UNDERSTAND THIS WILL DEPLOY A CONTAINER REGISTRY | Safety phrase |
+
+## Outputs
+
+- `outputs/compose.yml`
+- `outputs/htpasswd`
+- `outputs/status_matrix.json`
+- `outputs/audit_report.md`
+- Backups under `outputs/backups/`
+
+## Security Notes (v1)
+
+- Basic auth (htpasswd)
+- TLS termination expected via reverse proxy or Cloudflare Tunnel
+- Image signing handled upstream (cosign/notation integration planned)
+
+## EU Compliance
+
+| Aspect | Value |
+|---|---|
+| Data Residency | EU (Ireland - Dublin) |
+| Jurisdiction | Irish Law |
+| Images | Stored on Node B |

+  Restore runbook as executable checks. Validates recent backups, performs
+  safe, staged restore tests, and generates an audit report. Designed for
+  sovereign EU infrastructure. Triggers: 'disaster recovery', 'restore runbook',
+  'test restore', 'recovery drill', 'verify backups'.
+version: 1.0.0
+---
+
+# Disaster Recovery
+
+Tier 1 skill: convert restoration into **repeatable drills**.
+
+This skill assumes **backup-sovereign** produces run directories like:
+
+`backup-sovereign/outputs/runs/<node>_<label>_<timestamp>/`
+
+Each run should include:
+- `archive.tar.gz.age`
+- `manifest.json`
+- `ROOT.txt`
+- `PROOF.json`
+
+## Quick Start
+
+```bash
+export BACKUP_SKILL_DIR="$HOME/.claude/skills/backup-sovereign"
+export RUN_DIR=""                    # optional; auto-uses backup-sovereign pointer
+export DR_TARGET_BASE="$HOME/recovery-drills"
+export AGE_IDENTITY_FILE="$HOME/.config/age/keys.txt"
+
+export DRY_RUN=1
+export REQUIRE_CONFIRM=1
+export CONFIRM_PHRASE="I UNDERSTAND THIS CAN OVERWRITE RECOVERY TARGETS"
+
+./scripts/00_preflight.sh
+./scripts/10_validate_run.sh
+./scripts/20_restore_plan.sh
+
+export DRY_RUN=0
+./scripts/21_restore_apply.sh
+
+./scripts/30_verify_restored.sh
+./scripts/90_verify.sh
+./scripts/99_report.sh
+```
+
+## Inputs
+
+| Parameter | Required | Default | Description |
+|---|---:|---|---|
+| BACKUP_SKILL_DIR | Yes | (none) | Path to backup-sovereign skill |
+| RUN_DIR | No | (auto) | Backup run directory to restore |
+| DR_TARGET_BASE | No | ~/recovery-drills | Base directory for recovery drills |
+| AGE_IDENTITY_FILE | Yes | (none) | age private key file |
+| DRY_RUN | No | 1 | Apply scripts refuse unless DRY_RUN=0 |
+| REQUIRE_CONFIRM | No | 1 | Require confirmation phrase |
+| CONFIRM_PHRASE | No | I UNDERSTAND THIS CAN OVERWRITE RECOVERY TARGETS | Safety phrase |
+
+## Outputs
+
+- `outputs/status_matrix.json`
+- `outputs/audit_report.md`
+- `outputs/last_drill_target.txt`
+
+## Safety Guarantees
+
+1. **Default DRY_RUN=1**
+2. **Confirmation phrase required**
+3. **Staged restore only** (never writes to system paths)
+4. **Pre-restore validation** (artifacts exist, ROOT recomputation)
+5. **Post-restore verification** (file counts + spot-check)
+
+## EU Compliance
+
+| Aspect | Value |
+|---|---|
+| Data Residency | EU (Ireland - Dublin) |
+| Jurisdiction | Irish Law |
+| Encryption | age |

+# Recovery Playbook (Staged)
+
+## Purpose
+Turn restoration into a repeatable operational habit.
+
+## Staged Restore Policy
+- Never restore into system directories during drills.
+- Always restore into a timestamped target under DR_TARGET_BASE.
+
+## Minimum Drill
+1. Validate backup artifacts (exist + ROOT recomputation)
+2. Decrypt archive
+3. Extract archive
+4. Verify file count > 0
+5. Spot-check content
+
+## Service-Specific Production Restore
+Create a dedicated procedure per service:
+- VaultMesh Portal (Axum)
+- Node gateway
+- Reverse proxy (nginx)
+- Monitoring (Prometheus/Grafana)

+  (Docker) and optionally syncs selected records to Cloudflare.

+
+# DNS Sovereign (PowerDNS + Cloudflare Hybrid)
+
+This skill establishes **Node B** (or dedicated DNS node) as your sovereign
+authoritative DNS, with Cloudflare as an optional edge mirror / public resolver layer.
+
+## What v1.0.0 Does
+
+**PowerDNS Authoritative (Docker)**
+- Deploys PowerDNS authoritative server using sqlite backend
+- Enables the PowerDNS API
+- Creates a first zone (optional) via API
+- Produces an audit report + status matrix
+
+**Optional Cloudflare Sync**
+- Push a limited set of records (A/AAAA/CNAME/TXT) to Cloudflare using API token
+- Designed as a *mirror*, not source of truth
+
+## Quick Start
+
+```bash
+cd ~/.claude/skills/dns-sovereign
+
+# PowerDNS (required)
+export MODE="docker"
+export PDNS_PORT=53
+export PDNS_WEB_PORT=8081
+export PDNS_API_KEY="..."            # choose a strong random token
+export PDNS_DATA_DIR="$HOME/pdns"
+
+# Zone (optional but recommended)
+export ZONE_NAME="example.com"       # authoritative zone name (must end with . in PDNS API ops)
+export NS1_NAME="ns1.example.com"
+export NS2_NAME="ns2.example.com"
+
+# Cloudflare mirror (optional)
+export CF_API_TOKEN=""               # if set, sync scripts can run
+export CF_ZONE_NAME="example.com"    # Cloudflare zone to mirror into
+
+# Safety
+export DRY_RUN=1
+export REQUIRE_CONFIRM=1
+export CONFIRM_PHRASE="I UNDERSTAND THIS CAN CHANGE DNS"
+
+./scripts/00_preflight.sh
+./scripts/10_pdns_plan.sh
+
+export DRY_RUN=0
+./scripts/11_pdns_apply.sh
+
+# Optional: create zone + NS records in PDNS
+./scripts/20_zone_plan.sh
+export DRY_RUN=0
+./scripts/21_zone_apply.sh
+
+# Optional: mirror records to Cloudflare (does not pull)
+./scripts/30_cf_plan.sh
+export DRY_RUN=0
+./scripts/31_cf_apply.sh
+
+./scripts/90_verify.sh
+./scripts/99_report.sh
+```
+
+## Inputs
+
+| Parameter | Required | Default | Description |
+|---|---:|---|---|
+| MODE | Yes | docker | docker |
+| PDNS_API_KEY | Yes | (none) | PowerDNS API key |
+| PDNS_DATA_DIR | No | ~/pdns | Persistent storage |
+| PDNS_PORT | No | 53 | DNS port |
+| PDNS_WEB_PORT | No | 8081 | API/Web port |
+| ZONE_NAME | No | (empty) | Zone to create (e.g., example.com) |
+| NS1_NAME | No | ns1.<zone> | Primary NS hostname |
+| NS2_NAME | No | ns2.<zone> | Secondary NS hostname |
+| CF_API_TOKEN | No | (empty) | Cloudflare API token (for mirroring) |
+| CF_ZONE_NAME | No | (empty) | Cloudflare zone name |
+| DRY_RUN | No | 1 | Apply refuses unless DRY_RUN=0 |
+| REQUIRE_CONFIRM | No | 1 | Require confirmation phrase |
+| CONFIRM_PHRASE | No | I UNDERSTAND THIS CAN CHANGE DNS | Safety phrase |
+
+## Outputs
+
+- `outputs/compose.yml`
+- `outputs/pdns.conf`
+- `outputs/pdns_api_probe.json`
+- `outputs/status_matrix.json`
+- `outputs/audit_report.md`
+- `outputs/backups/<timestamp>/...`
+
+## Safety Guarantees
+
+1. Default **DRY_RUN=1**
+2. Confirmation phrase required
+3. Backups for compose + config
+4. Rollback scripts:
+   - stop/remove PDNS container (data preserved)
+   - delete zone (optional)
+   - remove mirrored Cloudflare records created by this skill (best-effort)
+
+## EU Compliance
+
+| Aspect | Value |
+|---|---|
+| Data Residency | EU (Ireland - Dublin) |
+| Jurisdiction | Irish Law |
+| Authoritative Source | PowerDNS on your node |
+| Mirror | Optional Cloudflare mirror |

+
+This skill treats Cloudflare as a **mirror**, not the source of truth.
+
+## Mirror Records File
+Create: outputs/mirror_records.json
+
+Example:
+[
+  {"type":"A","name":"app","content":"1.2.3.4","ttl":120},
+  {"type":"CNAME","name":"git","content":"app.example.com","ttl":120}

+
+## Rollback
+When mirroring, record IDs are saved in outputs/cloudflare_record_ids.txt.
+undo_cloudflare.sh will delete those IDs (best effort).

+
+## v1 Design
+- Authoritative server: powerdns/pdns-auth (Docker)
+- Backend: sqlite3 in PDNS_DATA_DIR
+- API enabled and published to localhost only
+
+## Production Hardening
+- Run behind firewall; restrict UDP/TCP 53 to known resolvers or public as needed
+- Keep API bound to localhost
+- Consider a second NS (ns2) on a separate node/provider for resilience
+- Back up PDNS_DATA_DIR using backup-sovereign

+description: >
+  Anchor a Merkle root (root_hex) to Ethereum using a minimal calldata transaction,
+  emit PROOF.json + tx metadata, with plan/apply/rollback and verification.
+  Consumes merkle-forest ROOT.txt (or explicit ROOT_HEX). Triggers: 'eth anchor',
+  'anchor root on ethereum', 'calldata tx', 'proof on chain'.
+version: 1.0.0
+---
+
+# ETH Anchor (Calldata TX)
+
+This skill anchors a **root_hex** to Ethereum by sending a small transaction
+with the root embedded in **data** (calldata). It outputs a proof receipt
+linking **ROOT.txt → tx hash → chain**.
+
+## Requirements
+- `cast` (Foundry) **or** `ethers`-compatible RPC with `curl` is possible; v1 uses `cast`.
+- RPC URL for the target network.
+- A funded private key (hot key) OR hardware wallet workflow (not implemented in v1).
+
+## Quick Start
+
+```bash
+cd ~/.claude/skills/eth-anchor
+
+# inputs
+export ROOT_FILE="$HOME/.claude/skills/merkle-forest/outputs/runs/<run>/ROOT.txt"
+# or: export ROOT_HEX="..."
+
+# chain
+export ETH_RPC_URL="https://..."
+export CHAIN_ID=1                     # 1 mainnet, 11155111 sepolia, etc
+export TO_ADDRESS="0x0000000000000000000000000000000000000000"  # burn/null is fine for data-only tx
+
+# signer
+export ETH_PRIVATE_KEY="0x..."        # ensure funded
+
+# safety
+export DRY_RUN=1
+export REQUIRE_CONFIRM=1
+export CONFIRM_PHRASE="I UNDERSTAND THIS WILL SEND AN ETH TRANSACTION"
+
+./scripts/00_preflight.sh
+./scripts/10_plan.sh
+
+export DRY_RUN=0
+./scripts/11_apply.sh
+
+./scripts/90_verify.sh
+./scripts/99_report.sh
+```
+
+## Inputs
+
+| Parameter | Required | Default | Description |
+|---|---:|---|---|
+| ROOT_FILE | No | (empty) | Path to ROOT.txt from merkle-forest |
+| ROOT_HEX | No | (empty) | Explicit root hex (overrides ROOT_FILE) |
+| ETH_RPC_URL | Yes | (none) | RPC endpoint |
+| CHAIN_ID | No | 1 | Chain id |
+| TO_ADDRESS | No | 0x000…000 | Recipient (data-only tx) |
+| GAS_LIMIT | No | 60000 | Gas limit |
+| VALUE_WEI | No | 0 | Value to send (normally 0) |
+| ETH_PRIVATE_KEY | Yes | (none) | Hot key for signing (v1) |
+| DRY_RUN | No | 1 | Apply refuses unless DRY_RUN=0 |
+| REQUIRE_CONFIRM | No | 1 | Require confirmation phrase |
+| CONFIRM_PHRASE | No | I UNDERSTAND THIS WILL SEND AN ETH TRANSACTION | Safety phrase |
+
+## Outputs (per run)
+
+`outputs/runs/<label>_<timestamp>/`
+- `root_hex.txt`
+- `tx_hash.txt`
+- `tx_receipt.json`
+- `PROOF.json`
+- `status_matrix.json`
+- `audit_report.md`
+
+## Notes
+- Data payload: `0x` + `root_hex` (32 bytes / 64 hex). If root_hex is not 32 bytes, v1 right-pads to 32 bytes.
+- This is a simple anchor. If you later want "contract-based attestations", we can add an EAS backend.

+## Method
+v1 anchors by sending a normal transaction with calldata set to 32-byte root.
+
+- to: 0x000...000 (null) by default
+- value: 0
+- data: 0x + root_hex (padded/truncated to 32 bytes)
+
+## Security
+- Prefer a dedicated small hot key funded only for anchoring.
+- For mainnet, consider hardware wallet signing in a later version.

+name: gitea-bootstrap
+description: >
+  Bootstrap a sovereign Git service on Node B using Gitea (Docker or native),
+  with two-phase plan/apply, backups, verification, and rollback. Creates an
+  admin user, configures SSH/HTTP, and outputs an audit report.
+  Triggers: 'install gitea', 'bootstrap gitea', 'self-host git', 'node b git',
+  'gitea plan', 'gitea rollback'.
+version: 1.0.0
+---
+
+# Gitea Bootstrap
+
+Tier 2 (Infrastructure Sovereignty): build **Node B** as your self-hosted Git authority.
+
+This skill supports two deployment modes:
+- **Docker** (recommended for fastest repeatability)
+- **Native** (system package + systemd)
+
+It is **plan/apply** gated with DRY_RUN and a confirmation phrase.
+
+## Quick Start
+
+```bash
+cd ~/.claude/skills/gitea-bootstrap
+
+# Choose mode
+export MODE="docker"                 # docker | native
+export NODE_NAME="node-b"
+
+# Network
+export HTTP_PORT=3000
+export SSH_PORT=2222                 # external SSH for git (docker mode)
+export DOMAIN="git.example.com"      # optional; for reverse proxy
+
+# Storage
+export DATA_DIR="$HOME/gitea"
+export BACKUP_DIR="outputs/backups"
+
+# Admin bootstrap (you'll be prompted to set password securely)
+export ADMIN_USER="sovereign"
+export ADMIN_EMAIL="sovereign@vaultmesh.org"
+
+# Safety
+export DRY_RUN=1
+export REQUIRE_CONFIRM=1
+export CONFIRM_PHRASE="I UNDERSTAND THIS WILL INSTALL AND CONFIGURE GITEA"
+
+./scripts/00_preflight.sh
+./scripts/10_plan.sh
+
+export DRY_RUN=0
+./scripts/11_apply.sh
+
+./scripts/90_verify.sh
+./scripts/99_report.sh
+```
+
+## Inputs
+
+| Parameter | Required | Default | Description |
+|---|---:|---|---|
+| MODE | Yes | docker | docker or native |
+| NODE_NAME | No | node-b | Identifier for reporting |
+| HTTP_PORT | No | 3000 | Gitea web port |
+| SSH_PORT | No | 2222 | SSH port for git (docker mode) |
+| DOMAIN | No | (empty) | Hostname if using reverse proxy |
+| DATA_DIR | No | ~/gitea | Data directory (repos, config, db) |
+| ADMIN_USER | Yes | (none) | Initial admin username |
+| ADMIN_EMAIL | Yes | (none) | Initial admin email |
+| DRY_RUN | No | 1 | Apply refuses unless DRY_RUN=0 |
+| REQUIRE_CONFIRM | No | 1 | Require confirmation phrase |
+| CONFIRM_PHRASE | No | I UNDERSTAND THIS WILL INSTALL AND CONFIGURE GITEA | Safety phrase |
+
+## Outputs
+
+- `outputs/compose.yml` (docker mode)
+- `outputs/gitea_app.ini` (rendered config template)
+- `outputs/status_matrix.json`
+- `outputs/audit_report.md`
+- Backups under `outputs/backups/`
+
+## Safety Guarantees
+
+1. Default **DRY_RUN=1**
+2. Confirmation phrase required
+3. Backups of generated configs + service definitions
+4. Rollback scripts for docker and native modes
+
+## EU Compliance
+
+| Aspect | Value |
+|---|---|
+| Data Residency | EU (Ireland - Dublin) |
+| Jurisdiction | Irish Law |
+| Git Data | Stored on Node B only |
+| Backups | Local outputs + optional offsite via backup-sovereign |
