# Changelog
All notable changes to Sorcery-Go are documented here. The format follows
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and the project
adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [Unreleased]
### Added
- **BTC 0.4.0 multi-arch cross-compilation support** (`pkg/toolchain/btc.go`)
- `BTCManifest` struct for structured manifest JSON parsing
- `BTCForge` extended with `CrossMode`, `TargetID`, `TargetTriple`,
`TargetMarch`, `CLib`, `Family`, `Manifest` fields
- `loadManifest()` reads `{SYS_LABEL}-manifest.json` sidecars
- `ListTargets()` enumerates all available golden images with manifest data
- `BuildEnv()` uses manifest CFLAGS/triple when available; falls back to
legacy derivation. Handles musl targets, cross-compiler naming
(`{triple}-gcc`), and `--sysroot` rewriting for extracted toolchains
- `rewriteSysroot()` helper replaces build-time sysroot paths with
the actual extraction path
- `StampBinary()` uses cross-assembler (`{triple}-as`) when available
- ISA flag table for AVX512, AVX2, SSE4_2, NEON, MIPS32, TILE
- SSE4_2 ISA tier added for Intel Atom and AMD APU targets that lack AVX
- 19 cross-compilation targets: Intel HEDT/Server (5), AMD Ryzen/EPYC (4),
AMD APU (4: apu-zn1 through apu-zn4), Intel Atom (4: silvermont, goldmont,
tremont, sierraforest), embedded (mipselr2, armv7, tilegx)
- New env vars: `BTC_TARGET_ID`, `BTC_CROSS`, `BTC_CLIB`, `BTC_TARGET_TRIPLE`
- **Shared CAS client** (`pkg/cas/`) — content-addressable store client
for the sorcery-go <-> Fester shared artifact cache
- `CheckArtifact` — DAG-aware cache check before build dispatch
- `PushFile` / `PushArtifact` — store .svb bundles and build outputs
- `RetrieveArtifact` / `RetrieveArtifactToFile` — fetch cached artifacts
- `Stats` — cache hit rate, utilization, artifact count
- Auto-initialized when Fester integration is active
- **BTC.sh toolchain integration** (`pkg/toolchain/btc.go`)
- `Probe()` — detect BTC.sh golden images at /opt/BTC
- `BuildEnv()` — return BTC-aware CC/CXX/CFLAGS/LDFLAGS
- `VerifyStamp()` — read .note.BTC ELF note and xattr stamps
- `StampBinary()` — apply forensic stamps (ELF note, xattr, debug symbols)
- Pipe-delimited format matching BTC.sh and Fester
- **Cauldron.BundleAndCache** — one-call bundle + CAS push method
- **Scheduler.Dispatch now CAS-aware** — checks shared CAS before
dispatching to Fester; skips builds for cached artifacts
- **FesterClient.CAS field** — shared CAS client embedded in the
Fester HTTP client, available to all cluster operations
- **Deterministic task IDs** — replaced `crypto/rand` with atomic counter +
nanosecond timestamp (`sync/atomic` + `time.Now().UnixNano()`). No
cryptographic randomness dependency remains in the codebase.
### Changed
- **Security model**: Firewall-first architecture replaces mTLS. Transport
security delegated to network boundary (OPNsense / IPFire). No application-
layer TLS certificates, key management, or CRL propagation required.
- **eBPF security** replaces AppArmor as primary enforcement mechanism
- `tomb_guard.bpf.c` — LSM hooks for file/inode protection
- `sorcery_filter.bpf.c` — cgroup filters for device/network whitelisting
- AppArmor profiles retained as fallback
- **License** changed from GPL-3.0 to AGPL-3.0-or-later
- **Fester cluster integration** — full delegation of distributed build
scheduling, node telemetry, and build dispatch to Fester
- **NVD API v2 client** with SQLite WAL cache replaces hardcoded CVE data
- **Sovereign Bundle (.svb)** format with ed25519 signatures and
per-file SHA-256 MANIFEST.txt
- **Port**: Fester default port changed from 8080 to 8181 to resolve conflict
with sorcery-go.
### Removed
- **All `crypto/rand` usage** — removed from `pkg/web/server.go` and
`cmd/sorcery/commands.go`. Zero active `crypto/rand`, `crypto/tls`, or
`crypto/x509` code paths remain in default builds.
- **`pkg/warding/keys.go`** — dead code gated behind `//go:build mtls`
build tag. Contained CA key generation logic that is no longer used.
- **`FesterTLS` config field** and `SORCERY_GO_FESTER_TLS` env var — no
longer needed with firewall-first model.
- **`TLSConfig()` method** on the Fester client — transport security is
now handled by the network boundary.
### Fixed
- Added missing `bytes` import to `state.go` (compile failure).
- Added `defer` mutex unlock in `Banish()` (deadlock on panic).
- Fixed BTC.sh SHA-256 checksum ordering (was computed before tarball creation).
- Added cycle detection to dependency solver (stack overflow on circular graphs).
- Fixed ELF note type mismatch in BTC stamp format (7 -> 1, now matches
BTC.sh NT_VERSION).
## [1.0.0] — 2026-03-17 — "The Sovereign Coven"
### Added
- **The Cauldron** — Go build engine with OverlayFS sandbox isolation
- **The Tablet** — ACID BoltDB journal for y/n configuration persistence
- **The Tomb** — content-addressable Merkle-tree storage for Essences
- **The Warding** — security layer with eBPF + OpenSnitch/Portmaster integration
- **The Coven** — firewall-isolated cluster with Fester-scheduled builds
- **Gaze** — reverse-path inventory query engine
- **Legal Sentinel** — license compliance with three posture templates
- **ICE** — Interactive Configuration Engine preserving the y/n query UX
- **Cauldron Portable Bin** — static ELF generation for standalone tools
- **Emergency Kit** — curated static bundle (busybox, gdisk, e2fsck, etc.)
- **Coven Mirror WebUI** — Cockpit-integrated dashboard
- **Bubble Tea TUI** — tmux-style build dashboard
- **Multi-arch support** — `--target x86_64|aarch64` and `--matrix`
- **Sub-Depends solver** — feature-aware DAG with Re-Forge triggers
- **Disaster Recovery Tome** — restore the entire Coven from backup
- **Toolchain Validator** — smoke-tests GCC/LLVM for SSP, PIE, LTO

# Contributing to Sorcery-Go
> *"The Coven grows stronger with every mage who joins the circle."*
Thank you for your interest in improving Sorcery-Go. This document describes
how to contribute code, spells, documentation, and toolchains to the
Sovereign Coven.
**Sorcery-Go is developed by dcos.net. It is not affiliated with Source Mage
GNU/Linux or sourcemage.org.**
## Code Contributions
1. **Fork & branch** — create a feature branch off `master`:
`git checkout -b feature/your-feature`
2. **Build & test** — every PR must pass `make build && make test`:
```bash
make build
go test ./pkg/...
```
3. **Style** — follow [Effective Go](https://go.dev/doc/effective_go) and
`gofmt -s`. Run `go vet ./...` before pushing.
4. **Doc comments** — every exported type and function must have a Go doc
comment that starts with the identifier name. See `pkg/dag/dag.go` for
the house style.
5. **Tests** — every new package must include a `_test.go` file. The DAG,
Warding, Legal, and Tomb packages already have tests you can use as
templates.
6. **Commit messages** — follow the conventional-commits style:
```
feat(cast): add --matrix flag for parallel arch builds
fix(tomb): handle empty epitaph in VerifyRoot
docs(security): add firewall rules reference for new deployments
```
## Spell Contributions (Grimoire)
New spells go under `grimoire/<section>/<spell>/` and must include:
- `DETAILS` — required metadata (see `docs/SPELL_SPEC.md`)
- `DEPENDS` — runtime/build/optional dependencies
- `BUILD` — compilation script (runs inside the OverlayFS sandbox)
- `CONFIGURE` — optional ICE y/n queries
Use `quill new <name>` to scaffold a new spell — it auto-hashes the source
tarball and emits the four files in the correct format.
## Toolchain Contributions
If you maintain a custom GCC/LLVM toolchain that should be admitted to the
Coven:
1. Add a `TOOLCHAIN.md` (see `docs/TOOLCHAIN_SPEC.md`) under
`/opt/sorcery-go/toolchains/<triple>/`.
2. Run `pkg/toolchain.Validate(path)` — the report must show `Passed: true`.
3. Sign the toolchain directory with your PGP key.
## Documentation
The SGDS (Sorcery-Go Documentation Standard) lives in `docs/METADATA.md`.
Every new module or major feature must include a corresponding markdown
file. Keep the arcane vocabulary consistent — see `docs/RITUAL_OF_CASTING.md`
for the canonical names (Cauldron, Tomb, Warding, Sanctum, Coven, etc.).
## Legal
Sorcery-Go is developed by dcos.net and is not affiliated with Source Mage
GNU/Linux or sourcemage.org. By submitting a pull request you agree to license
your contribution under AGPL-3.0-or-later. The Legal Sentinel's
`strict_copyleft` posture is the default for the project itself — please do
not introduce proprietary code.
## Code of Conduct
Be excellent to each other. The Coven is a circle of mutual respect —
hostility will not be tolerated.

# Sorcery-Go — The Sovereign Coven
**Sorcery-Go is an independent project developed by dcos.net. It is not
produced by, affiliated with, endorsed by, or connected to Source Mage
GNU/Linux or sourcemage.org in any official capacity.**
Sorcery-Go is a high-concurrency, source-based infrastructure management
suite. It implements a spell format compatible with Source Mage GNU/Linux
grimoires for convenience, but the two projects have separate maintainers,
separate codebases, and separate governance.
It organizes independent Linux Sanctums (LXC containers or bare-metal hosts)
into a unified Coven, connected by firewall-isolated Ley-Lines. Every spell
cast through the Cauldron is sealed as a content-addressable Essence inside the
Tomb, defended by the Warding, and audited by the Legal Sentinel.
## Core Components
| Component | Role | Modern Upgrade |
|------------------|-----------------------------------------|----------------------------------------------------------|
| The Cauldron | Build engine that boils source to bins | High-concurrency Go + OverlayFS sandboxes |
| The Tablet | Persistent y/n configuration memory | ACID BoltDB (journalled, recoverable) |
| The Tomb | Binary storage / CAS | Merkle-tree, deduplicated Sarcophagi |
| The Warding | Security and integrity boundary | eBPF Tomb Guard + cgroup filters + OpenSnitch/Portmaster + firewall isolation |
| The Sanctum | Isolated runtime | LXC / Podman / Firecracker / baremetal (reflink hydration)|
| The Coven | Distributed cluster | Firewall-isolated Ley-Lines, Fester-scheduled builds |
| The Gaze | Inventory and audit query | Reverse path index, SBOM export |
| The Legal Sentinel| License compliance | SPDX/CycloneDX, 3 posture templates |
| The Coven Mirror | WebUI (Cockpit-integrated) | Monaco IDE, Fleet dashboard, Portable Bin |
## Security Model
Sorcery-Go uses a **firewall-first security architecture**. Transport security
is delegated to the network boundary (OPNsense / IPFire). There is no
application-layer TLS or mTLS — no certificate management, no key rotation,
no CRL propagation. The defense-in-depth model relies on:
1. **eBPF LSM (Tomb Guard)** — in-kernel enforcement blocking writes to the Tomb
2. **eBPF cgroup filters** — device and network control
3. **Network firewall** — OPNsense / IPFire isolating the Coven
4. **Per-process filtering** — OpenSnitch or Portmaster
5. **Content-addressing** — Merkle root + per-blob hashing for integrity
6. **Quarantine** — cgroup freezer for containment
All `crypto/rand`, `crypto/tls`, and `crypto/x509` code has been removed.
Task IDs are generated deterministically using atomic counters and nanosecond
timestamps.
## Quick Start
### Drop into an existing Source Mage-compatible chroot
If you have a Source Mage chroot with a modern toolchain (GCC 12+, glibc 2.35+):
```bash
make build
sudo make drop-in # installs to /usr/local/sbin/sorcery-go
sudo sorcery-go cast busybox --static --default
sorcery-go gaze install busybox
sudo sorcery-go web --port 8080
```
Full guide: [docs/INSTALL.md](docs/INSTALL.md)
### Resurrect an old Source Mage tarball (0.62-11 / 0.63 test)
The 8-phase staging pipeline in `scripts/smgl-getting-started.sh` walks you
through purging GRUB 1, injecting a modern kernel, swapping to the live test
grimoire, step-upgrading the toolchain ladder, and dropping in sorcery-go.
Note: Source Mage tarballs are produced by the Source Mage project at
sourcemage.org. Sorcery-Go can use them but is not affiliated with that
project.
Full guide: [docs/GETTING_STARTED_SMGL_CHROOT.md](docs/GETTING_STARTED_SMGL_CHROOT.md)
## BTC.sh Cross-Compilation Integration
Sorcery-Go integrates with BTC.sh for multi-architecture cross-compilation via
`pkg/toolchain/btc.go`. The integration probes for golden images, parses
manifest JSON sidecars, and configures build environments for 19 supported
targets:
| Family | Targets | ISA Tiers |
|------------------|----------------------------------------------------------------|------------------|
| Intel HEDT/Server| haswell, haswell-ep, skylake, skylake-x, skylake-server | AVX2, AVX512 |
| AMD Ryzen/EPYC | znver1, znver2, znver3, znver4 | AVX2, AVX512 |
| AMD APU | apu-zn1, apu-zn2, apu-zn3, apu-zn4 | AVX2 |
| Intel Atom | atom-silvermont, atom-goldmont, atom-tremont, atom-sierraforest| SSE4_2 |
| Embedded | mipselr2, armv7, tilegx | MIPS32, NEON, TILE|

# Sorcery-Go Architecture
## 1. The Core Thesis
Traditional source-based package management suffers from sequential fragility:
if a single shell script fails, the entire system state becomes ambiguous.
Sorcery-Go replaces procedural "instructional scripts" with declarative state
managed by Go-grade concurrency and ACID transactions.
## 2. The Three Pillars
### I. Deterministic Isolation (The Sandbox)
- **Old way:** `make install` writes directly to the live root. If it fails, the
system is tainted.
- **Go logic:** Every build occurs in an OverlayFS sandbox. The compiler sees
the system, but the system never sees the compiler.
- **Result:** Installations are atomic — they either succeed completely and are
committed, or they fail and vanish without a trace.
### II. Relational Intelligence (The DAG)
- **Old way:** Procedural loops check dependencies one by one.
- **Go logic:** The entire Grimoire is indexed into a directed acyclic graph
with feature-aware edges (Build / Runtime / Optional + sub-depends).
- **Result:** Parallelism is no longer a guess — the engine knows exactly which
spells can be built simultaneously without a race condition.
### III. The Single Source of Truth (BoltDB)
- **Old way:** Flat text files in `/var/lib/sorcery` that can be partially
written or corrupted.
- **Go logic:** A transactional, ACID-compliant KV store (bbolt) journals every
intent.
- **Result:** If the power cuts out, the recovery engine reads the journal and
resumes the exact byte-stream where it left off.
## 3. System Map

```
## 4. Lifecycle of a Spell
1. **Query** — User defines intent via CLI, TUI, or WebUI.
2. **Resolve** — Sub-Depends Solver ensures every library variant is compatible.
3. **Forge** — Master shards the build; workers execute in isolated namespaces.
Distributed scheduling is delegated to Fester when a cluster is active.
4. **Sign** — Resulting binary is hashed and stored as a Sarcophagus in the Tomb.
5. **Hydrate** — Target Sanctums are atomically updated via reflink/hardlink swaps.
6. **Verify** — Warding recomputes the Merkle root on first execution; mismatch
triggers quarantine.
## 5. Toolchain Synergy
| Tool | Role | Logic |
|-----------|-----------------|-------------------------------------------------------------|
| Quill | The Scribe | Type-safe metadata generation. No more sed hacking. |
| Sorcery | The Engine | High-concurrency worker-stealing build orchestration. |
| Cauldron | The Blacksmith | Image composition via JSON/YAML manifests. |
| Gaze | The Eye | Reverse-path inventory + SBOM export. |
| Warding | The Shield | eBPF Tomb Guard + OpenSnitch/Portmaster + firewall isolation.|
| Legal | The Lawyer | License policy + SBOM + attribution bundles. |
| BTC.sh | The Forge | Sovereign cross-compilation across 19 target architectures. |
## 6. Why Go
- **Static binaries** — The entire toolchain is one binary. It can repair a
system even if glibc or bash is broken.
- **Concurrency** — Goroutines handle thousands of package checks with minimal
RAM.
- **Low-level access** — Direct syscall management of namespaces and mounts
without external wrappers.
## 7. Deployment Targets
- LXC / LXD containers managed by Cockpit
- Podman rootless containers
- Firecracker micro-VMs
- Bare-metal Source Mage hosts (systemd or OpenRC)
- Immutable infrastructure (squashfs ISOs from the Cauldron)
- CI/CD pipelines (automated spell testing + essence promotion)
The eBPF Tomb Guard provides in-kernel enforcement that works uniformly
across all of the above runtimes — no per-runtime profile syntax needed.
## 8. Architecture Summary
| Layer | Component | Tech Stack |
|-----------|---------------|---------------------------------------------------|
| Logic | Sorcery-Go | Go (static binary) |
| Storage | Tomb | Content-addressable Merkle CAS |
| Scheduling| Fester | DAG-driven distributed build execution (port 8181)|
| Security | Warding | eBPF LSM + cgroup filters + firewall + OpenSnitch |
| Compliance| Legal Sentinel | SPDX / CycloneDX |

# Disaster Recovery Tome
If your Master Sanctum is physically destroyed, or the primary disk suffers a
critical failure, this is how you rebuild the entire Coven using only your
encrypted backups.
## Sacred Artifacts
To perform this reconstruction you need two things:
1. **The Tablet Backup** — `tablet.db.gpg` — your configuration, y/n choices,
and Merkle roots.
2. **The Tomb Backup** — `tomb.tar.gz` or a remote mirror — the actual
forged binaries.
## I. Reconstructing the Master Node
If the Master is gone, designate a new host.
```bash
# 1. Deploy the engine to the new host
make build && sudo make drop-in
# 2. Restore the Tablet (the "memory" of every spell ever cast)
gpg --decrypt tablet.db.gpg > /var/lib/sorcery-go/state/state.db
# 3. Re-seed the Tomb
tar xzf tomb.tar.gz -C /var/lib/sorcery-go/
# 4. Re-initialise the Cauldron — the engine scans the restored Tablet
# and Tomb to rebuild the internal search indexes
sorcery-go init --force
```
## II. Re-Establishing the Coven (Worker Nodes)
Workers are connected to the Master via plain HTTP behind the network firewall.
No certificates or key exchange is needed — just ensure the firewall rules
allow traffic on the sorcery-go (8080) and Fester (8181) ports.
```bash
# 1. Verify network connectivity to the new Master
sorcery coven pulse
# 2. If workers were using a Fester controller, update its URL
# (set in /etc/sorcery-go/config.yaml or SORCERY_GO_FESTER_URL env var)
```
If the workers respond with a green pulse, the Coven is restored.
## III. The Shadow-Forge Validation
Once the Coven is back online, verify that the restored Essences were not
corrupted during the failure:
```bash
# Deep Gaze — recompute the Merkle root of every file in the Tomb and
# compare against the restored Tablet entries
sorcery tomb verify --all
# Ghost Build — pick a core tool (like busybox) and re-forge it in a
# temporary sandbox. The new binary must match the restored Essence.
sorcery cast busybox --static --default
```
## IV. Restoring the Sanctums (LXC Containers)
Because hydration uses reflinks or hardlinks, a simple file restore will not
work for containers — the links are broken. Run the Re-Hydration Ritual:
```bash
# Reads the Tablet to see which Essences belong in which containers,
# then re-links them from the Tomb
sorcery reanimate --all-containers
```
## V. Backup Strategy
| Rule | Action | Frequency |
|-------------------|-----------------------------------------------------|-----------|
| Rule of Three | One local, one off-site, one cloud backup | Daily |
| Immutable Seal | Sign every `tablet.db` backup with a hardware key | Per change|
| Mirror Ritual | Use Fester CAS replication to keep warm standby | Real-time |
## VI. Verification Checklist
After reconstruction, verify each layer:
- [ ] `sorcery coven pulse` — every node green
- [ ] `sorcery tomb verify --all` — zero Merkle mismatches
- [ ] `sorcery ward status` — eBPF Tomb Guard active
- [ ] `sorcery legal audit` — zero license violations
- [ ] `gaze whereis /usr/bin/bash` — owned by `coreutils`
- [ ] Cast a smoke-test spell: `sorcery cast busybox --static --default`

# Essence Specification (.ess)
> *"Every Essence is sealed with a Merkle root. If a single bit flips, the Warding rejects it."*
## 1. File Format
An Essence is not a single file — it is a logical bundle stored in the Tomb:
```
/var/lib/sorcery-go/tomb/
├── epitaphs/ # metadata sidecars
│ └── <merkle_root>.json # the Sarcophagus
└── blobs/ # content-addressed file bytes
├── ab/
│ ├── abc123... # one file, named by its sha256
│ └── abd456...
└── cd/
└── cdef789...
```
## 2. Sarcophagus (Epitaph)
Every Essence has an **Epitaph** — a JSON sidecar that records the metadata.
```json
{
"essence_id": "9f4e2a8b...",
"spell_name": "wget",
"version": "1.21.4",
"variant_hash": "7c3d1e9f...",
"arch": "x86_64",
"linkage": "dynamic",
"config": {
"ssl": true,
"ipv6": true,
"nls": false
},
"files": {
"/usr/bin/wget": "abc123...",
"/usr/share/man/man1/wget.1.gz": "def456..."
},
"created_at": "2026-03-17T22:07:18Z",
"toolchain": "gcc-15.1.0-musl",
"license": "GPL-3.0-or-later"
}
```
## 3. Variant Hash
The Variant Hash is the "Soul" of a binary. Every unique combination of
`(version, y/n flags, arch, toolchain, linkage)` produces a unique hash:
```
variant_hash = sha256(spell_name || version || sorted(flags) || arch || toolchain || linkage)
```
Two different flag combinations never collide in the Tomb — this lets the
Coven simultaneously hold multiple "flavors" of the same spell.
## 4. Merkle Root
The `essence_id` is the Merkle root of the file set:
```
merkle_root = sha256( concat( sort(paths) || file_hashes ) )
```
If any file in the Sarcophagus changes — even by a single bit — the
recomputed root diverges from the stored `essence_id` and the Warding
rejects the Essence as **Tainted**.
## 5. Linkage Specification
| Type | Libc | Use Case |
|------|------|----------|
| `dynamic` | glibc | Standard LXC fleet (small footprint, central patching) |
| `static` | musl | Portable Tool Bin (runs on any Linux kernel) |
| `hermetic` | musl + bundle | AppImage-style self-contained Essence |
## 6. Multi-Arch Essences
The `arch` field prevents the Hydration engine from accidentally mapping
x86_64 binaries into an AArch64 container:
```json
{
"arch": "aarch64",
"instruction_set": "ARMv8-A",
"merkle_root": "sha256:9f4e2a8b..."
}
```
## 7. PGP Attestation
While the Coven handles internal Merkle sealing, the Grimoire itself is
expected to be PGP-signed by the High Mage:
```bash
gpg --detach-sign -a grimoire/libs/openssl/DETAILS
sorcery cast openssl --verify-pgp
```
The Tablet records who signed each spell — the WebUI shows a "Trusted Source"
badge next to the Essence in the Tomb.

# Getting Started with an existing Source Mage chroot
> *"Resurrect the ancient tarball. Strip the relics. Drop in the new engine."*
**Note:** Sorcery-Go is developed by dcos.net and is not affiliated with Source
Mage GNU/Linux or sourcemage.org. This guide explains how to use Sorcery-Go
with Source Mage chroots (which are produced by the Source Mage project). The
two projects are independent.
This guide walks you through bringing a frozen Source Mage chroot tarball
(the classic 0.62-11 release or a 0.63 test branch) into the modern era,
then dropping in `sorcery-go` as the new engine — coexisting with the
legacy Bash `sorcery` so you can migrate at your own pace.
The whole flow is automated by **`scripts/smgl-getting-started.sh`**. This
document is the long-form companion: it explains *why* each phase exists,
what to do when something breaks, and how the host-side and chroot-side
subcommands fit together.
---
## Why this guide exists
Source Mage hasn't seen an official stable ISO update in years. If you
boot a raw 0.62-11 tarball on modern hardware it will crash on two fronts:
1. **Ancient kernel panic** — no support for modern storage / NVMe controllers.
2. **GRUB 1 (Legacy)** — can't read GPT partition tables or modern ext4 metadata.
On top of that, the toolchain inside the tarball is frozen at ~2017-era
GCC/glibc, which can't compile modern spell recipes (GCC 15+, 6.x kernels,
LLVM 22). So we stage everything inside a chroot from a modern host, rip
out the broken pieces, and inject modern scaffolding before we ever try
to boot.
---
## The 8-phase pipeline
| Phase | What | Where | Script subcommand |
|-------|------|-------|-------------------|
| 1 | Extract + mount API filesystems | host | `extract`, `mount` |
| 2 | Purge GRUB 1, cast GRUB 2 | chroot | `chroot-purge-grub1`, `chroot-cast-grub2` |
| 3 | Strip old kernel, inject modern host-built kernel | host | `inject-kernel` |
| 4 | Rewrite fstab with UUID identifiers | host | `fix-fstab` |
| 5 | Inject modern sorcery engine (Bash) | host | `inject-sorcery` |
| 6 | Set conservative CFLAGS for the step-upgrade | chroot | (part of `chroot-stepupgrade`) |
| 7 | Cut over from dead stable grimoire to live test branch | chroot | `chroot-scribe-test` |
| 8 | Step-upgrade ladder: make → binutils → gcc → glibc | chroot | `chroot-stepupgrade` |
| 9 | Drop in sorcery-go and init | both | `inject-sorcery-go` (host) + `chroot-init-sorcery-go` (chroot) |
---
## Prerequisites
On your **modern host OS** (the machine doing the surgery):
- root (sudo) — required for mount, chroot, setcap
- `tar`, `wget`, `bash` ≥ 4
- A modern kernel build at `/usr/src/linux/arch/x86/boot/bzImage` (or wherever your custom 6.x kernel lives)
- The matching module tree at `/lib/modules/<version>`
- Go ≥ 1.21 (only if you want to build sorcery-go yourself; you can also use a pre-built binary)
- `setcap` (from `libcap`) — optional, for non-root OverlayFS
On the **chroot tarball**:
- `source-mage-x86_64-0.62-11.tar.xz` (or similar test-branch tarball)
- ~2 GB free disk for the extracted rootfs + state
---
## Walkthrough
### Phase 1 — Extract + mount (host)
```bash
# From the sorcery-go project root:
sudo ./scripts/smgl-getting-started.sh extract \
~/Downloads/source-mage-x86_64-0.62-11.tar.xz \
/mnt/AI/sourcemage_root
sudo ./scripts/smgl-getting-started.sh mount /mnt/AI/sourcemage_root
```
This bind-mounts `/dev`, `/proc`, `/sys` into the chroot and copies your
host's `/etc/resolv.conf` so the chroot has working DNS. Don't skip the
resolv.conf copy — without it every `wget` inside the chroot fails with
"connection timed out" and you'll waste an hour debugging.
### Phase 5 — Inject the modern Bash sorcery engine (host)
Do this *before* entering the chroot so the modern `cast` / `scribe` /
`dispel` scripts are in place when you arrive:
```bash
sudo ./scripts/smgl-getting-started.sh inject-sorcery /mnt/AI/sourcemage_root
```
This downloads `https://sourcemage.org/codex/sorcery-stable.tar.bz2` and
overlays its `usr/` and `etc/sorcery/` into the chroot. If the download
fails (firewall, dead mirror), pass a local copy:
```bash
sudo ./scripts/smgl-getting-started.sh inject-sorcery \
/mnt/AI/sourcemage_root ~/Downloads/sorcery-stable.tar.bz2
```
### Phase 3 — Inject a modern kernel (host)
You cannot compile a 6.x kernel with the 2017-era GCC inside the chroot —
it'll segfault. Build the kernel on your modern host first, then slide it
in:
```bash
sudo ./scripts/smgl-getting-started.sh inject-kernel \
/mnt/AI/sourcemage_root \
/usr/src/linux/arch/x86/boot/bzImage \
/lib/modules/6.12.4-custom
```
The script purges `/boot/vmlinuz*`, `/boot/initrd*`, and `/lib/modules/*`
before copying the new files in, so there's no risk of the bootloader
finding a stale kernel.
### Drop in sorcery-go (host)
Now is the time to drop the new engine in — but **do not init it yet**.
The chroot's glibc is still ancient; `sorcery-go init` would index a
grimoire it can't actually cast against.
```bash
# Build it first if you haven't:
make build
sudo ./scripts/smgl-getting-started.sh inject-sorcery-go \
/mnt/AI/sourcemage_root
```
This installs to `/usr/local/sbin/sorcery-go` (NOT `/usr/sbin/sorcery` —
the legacy Bash binary stays put). State goes to `/var/lib/sorcery-go/`,
completely separate from `/var/lib/sorcery/`.
### Phase 4 — Fix fstab (host)
```bash
sudo blkid /dev/sdX1 # find your root partition's UUID
sudo blkid /dev/sdX2 # and boot, if separate
sudo ./scripts/smgl-getting-started.sh fix-fstab \
/mnt/AI/sourcemage_root \
XXXX-XXXX-XXXX-XXXX \
YYYY-YYYY
```
The original fstab is backed up to `etc/fstab.pre-sorcery-go.bak`.
### Enter the chroot
```bash
sudo ./scripts/smgl-getting-started.sh enter /mnt/AI/sourcemage_root
```
This `chroot`s in with a login shell and copies the script itself into
`/usr/local/sbin/smgl-getting-started.sh` so the `chroot-*` subcommands
work from inside.
### Phase 2 — Purge GRUB 1, cast GRUB 2 (chroot)
```bash
smgl-getting-started.sh chroot-purge-grub1
smgl-getting-started.sh chroot-cast-grub2
```
`chroot-cast-grub2` will likely **fail** at this point — the 2017-era
toolchain can't compile modern GRUB. That's fine; skip it. After Phase 8
completes you can run `grub-install` from your modern host instead:
```bash
# From the host, after the step-upgrade:
sudo grub-install --boot-directory=/mnt/AI/sourcemage_root/boot /dev/sdX
```
### Phase 7 — Cut over to the test grimoire (chroot)
```bash
smgl-getting-started.sh chroot-scribe-test
```
This drops the dead `stable` codex and anchors `scribe` to the live `test`
branch:
```
scribe remove stable
scribe add test from git://download.sourcemage.org/smgl/grimoire.git
```
The `test` branch is where the active development happens — modern spells
for GCC 15/16, LLVM 22, Firefox 151, and 6.x kernel configs land there
daily. The `stable` grimoire is a museum piece; don't waste time on it.
If `git://` is firewalled, the script falls back to `https://` automatically.
### Phase 8 — Step-upgrade the toolchain (chroot)
This is the most fragile phase. The script walks the ladder in the
correct order:
```bash
smgl-getting-started.sh chroot-stepupgrade
```
What it does, in order:
1. **Phase 6 (prep)** — writes conservative `OPTIMIZATION_FLAGS="-O2 -march=native"`
to `/etc/sorcery/config` and disables experimental GCC flags. This
prevents the ancient compiler from choking on modern syntax variations.
2. **8.1 `cast make`** — modern make first, so the rest of the ladder has
a working build system.
3. **8.2 `cast binutils`** — modern assembler/linker so modern binary
headers parse correctly.
4. **8.3 `cast gcc`** — an intermediate GCC that can parse modern syntax
but can still be compiled by the ancient root compiler. If `cast gcc`
tries to jump straight to GCC 15 and fails, edit the spell version
downward (GCC 9 or 10 is a safe stepping stone).
5. **8.4 `cast glibc`** — the cutover. Once glibc builds, the runtime
shifts under your feet: modern syscall wrappers (`statx`, `clone3`)
are now bound to the chroot.
**If any step segfaults**, don't panic. Use the escape hatch from the
path document: build the offending package statically on your modern
host and copy the binary into the chroot's `/usr/local/bin/`:
```bash
# On the host:
gcc -static -o /tmp/modern-gcc-wrapper ...
cp /tmp/modern-gcc-wrapper /mnt/AI/sourcemage_root/usr/local/bin/
# Or copy a whole modern compiler:
cp -a /usr/bin/gcc-something /mnt/AI/sourcemage_root/usr/local/bin/gcc-host
```
### Phase 9 — Init sorcery-go (chroot)
Now that the toolchain is modern, init the Go engine:
```bash
smgl-getting-started.sh chroot-init-sorcery-go
```
This runs `sorcery-go init --force` against the test grimoire, indexes
every spell into memory, and prints the spell count. You should see
thousands of spells indexed on a real test-branch grimoire.
Try your first Go-powered cast:
```bash
sorcery-go gaze depends wget
sudo sorcery-go cast busybox --static --default
sorcery-go tomb list
```
Launch the Coven Mirror WebUI:
```bash
sudo sorcery-go web --port 8080
```
### Leave + unmount (host)
```bash
# Inside the chroot:
exit
# Back on the host:
sudo ./scripts/smgl-getting-started.sh unmount /mnt/AI/sourcemage_root
```
The rootfs is now safe to tar up, dd onto a partition, or NFS-export.
---
## Troubleshooting
### "dispel: command not found" inside the chroot
You skipped Phase 5 (`inject-sorcery`). Leave the chroot, run
`inject-sorcery` from the host, then re-enter.
### "scribe add test" fails with SSL errors
The chroot's CA certificates are 9 years old. Two options:
1. Use the https fallback (the script tries it automatically).
2. Copy modern certs from the host:
```bash
sudo cp /etc/ssl/certs/ca-certificates.crt \
/mnt/AI/sourcemage_root/etc/ssl/certs/ca-certificates.crt
```
### "cast gcc" segfaults
The 2017-era compiler can't bootstrap a modern GCC. Use the escape hatch:
copy a host-built intermediate GCC (9 or 10) into the chroot's
`/usr/local/bin/`, then re-run `cast gcc` — it'll use the host binary as
the bootstrap compiler.
### "cast glibc" fails with "kernel headers too old"
The chroot's `linux-headers` are ancient. Cast a modern linux-headers
spell first:
```bash
cast linux-headers
cast glibc
```
### `sorcery-go init` reports 0 spells indexed
You're pointing at the wrong grimoire path. Check what scribe indexed:
```bash
ls /var/lib/sorcery/codex/
# Should show: test/ (and possibly stable/ if you didn't remove it)
```
Then set `SORCERY_GO_GRIMOIRE=/var/lib/sorcery/codex/test` and re-run
`sorcery-go init --force`.
### The chroot's network is dead
You probably skipped the `resolv.conf` copy in Phase 1. From the host:
```bash
sudo cp /etc/resolv.conf /mnt/AI/sourcemage_root/etc/resolv.conf
```
If your host uses `systemd-resolved`, the actual resolv.conf is at
`/run/systemd/resolve/resolv.conf` — copy that instead.
---
## Coexistence with legacy Bash sorcery
After the full pipeline completes, both engines live in the chroot:
| Tool | Binary | State | Reads grimoire |
|------|--------|-------|----------------|
| Legacy Bash sorcery | `/usr/sbin/cast` | `/var/lib/sorcery/` | `/var/lib/sorcery/codex/test/` |
| Sorcery-Go | `/usr/local/sbin/sorcery-go` | `/var/lib/sorcery-go/` | same (read-only) |
They never touch each other's state. You can switch freely:
```bash
sudo cast wget # legacy Bash cast
sudo sorcery-go cast wget # new Go cast
```
A broken `sorcery-go cast` never affects the Bash install, and vice versa.
---
## Next steps
- **Disaster recovery**: see `docs/DISASTER_RECOVERY.md` for how to back
up the Tomb and Tablet once you've cast real spells.
- **Coven Mirror WebUI**: see `docs/QUICKSTART.md` for the dashboard tabs.
- **Warding setup**: see `docs/SECURITY.md` for eBPF Tomb Guard and
firewall configuration once the chroot is booted on bare metal.
- **Custom toolchains**: see `docs/TOOLCHAIN_SPEC.md` if you want
sorcery-go to use your own GCC/LLVM instead of the chroot's defaults.

# Installing Sorcery-Go in an existing Source Mage chroot
> *"Drop the binary in. Cast your first spell. The Coven awakens."*
This is the definitive drop-in guide. After following it you will have a
working `sorcery-go` binary living alongside the legacy Bash `sorcery`,
reading the same grimoire, able to cast real spells end-to-end.
## Prerequisites
| Requirement | Why | Check |
|-------------|-----|-------|
| Source Mage chroot | We reuse its grimoire | `ls /var/lib/sorcery/codex/grimoire` |
| Go ≥ 1.21 | Build the binary | `go version` |
| root (sudo) | Mount OverlayFS, install to /usr/local/sbin | `id -u` == 0 |
| Linux ≥ 4.15 | OverlayFS + cgroup v2 freezer | `uname -r` |
| `bash`, `tar`, `gpg` | Spell sourcing + unpack + PGP | `which bash tar gpg` |
Optional but recommended:
- `setcap` (from `libcap`) — for running the binary as non-root with CAP_SYS_ADMIN
- `bpftool` — for loading eBPF Tomb Guard programs
- `lxc-freeze` or `systemctl` — for the Warding's quarantine logic
## 1. Build
```bash
cd sorcery-go
make build
```
This produces `./build/sorcery`. The build is CGO-free by default so the
binary is portable across glibc/musl hosts.
## 2. Drop-in install
The one-shot installer:
```bash
sudo ./scripts/bootstrap.sh
```
This will:
1. Build the binary (if `./build/sorcery` doesn't exist).
2. Install it to `/usr/local/sbin/sorcery-go` (NOT `/usr/sbin/sorcery` —
the legacy Bash sorcery stays untouched).
3. Create `/var/lib/sorcery-go/{state,tomb,build,log}` — separate from
`/var/lib/sorcery` so both tools can coexist.
4. Apply `CAP_SYS_ADMIN`, `CAP_CHOWN`, `CAP_DAC_OVERRIDE` via `setcap`.
5. Initialise the bbolt state DB at `/var/lib/sorcery-go/state/state.db`.
6. Walk the existing grimoire at `/var/lib/sorcery/codex/grimoire` and
index every spell into memory (printed count should be in the
thousands on a real SMGL install).
7. Install the systemd unit (or OpenRC init script, autodetected).
8. Optionally load the eBPF Tomb Guard programs.
Or, equivalently, with `make`:
```bash
sudo make drop-in
```
## 3. Verify
```bash
# State DB is alive
sorcery-go init
# Grimoire index works
sorcery-go gaze depends wget
# → 📜 Dependency tree for wget (5):
# binutils
# glibc
# linux-headers
# openssl
# zlib
# Tomb is empty (nothing cast yet)
sorcery-go tomb list
# Warding is active
sorcery-go ward status
```
## 4. Cast your first spell
```bash
# Static build of busybox — runs without root if you applied setcap
sudo sorcery-go cast busybox --static --default
```
What happens:
1. `grimoire.IndexAll` walks `/var/lib/sorcery/codex/grimoire` and finds `busybox`.
2. `warding.VerifySpell` checks for a PGP signature on `DETAILS.asc` (skipped if absent).
3. `legal.Sentinel.Validate` checks the license (GPL-2.0 — allowed under `strict_copyleft`).
4. `cast.Pipeline.Execute` runs:
- **Summon** — `http.Get` downloads the source tarball to `/var/spool/sorcery-go/`.
- **Verify** — sha512 hash is computed in-stream and compared to `SOURCE_HASH`.
- **Sandbox** — `sandbox.New` mounts an OverlayFS at `/var/lib/sorcery-go/build/busybox-<taskID>/`.
- **Unpack** — `tar -xf` extracts the source into the merged view.
- **ICE** — `cast.RunICE` parses `CONFIGURE` for `config_query` directives and prompts (or uses `--default` to accept defaults).
- **Build** — `bash -e BUILD` runs inside the sandbox with `CLONE_NEWNS | CLONE_NEWUTS`.
- **Collect** — `filepath.Walk` of the OverlayFS `upper` dir produces the manifest.
- **Ingest** — every file is sha256-hashed and copied into `/var/lib/sorcery-go/tomb/blobs/<ab>/<hash>`.
- **Seal** — the Sarcophagus epitaph (JSON) is written to `tomb/epitaphs/<merkleRoot>.json`.
- **Journal** — the bbolt Journal bucket records `StateInstalled`.
5. `sorcery-go gaze install busybox` lists every file owned by the Essence.
6. `sorcery-go tomb list` shows the new Essence in the Tomb.
## 5. Launch the Coven Mirror WebUI
```bash
sudo sorcery-go web --port 8080
```
Open `http://localhost:8080` in a browser. You'll see:
- **Grimoire** tab — every spell in the index, searchable.
- **Tomb** tab — every Essence, with its Merkle seal.
- **Pulse** tab — Coven node list (just `self` until you join a cluster).
- **Sanctum** tab — Warding status (green when eBPF Tomb Guard is active).
- **Portable Bin** tab — static ELF downloads.
- **Compliance** tab — license heatmap + SBOM export.
The WebUI's `POST /api/v1/cast` triggers a real cast pipeline; the
`/api/v1/stream/{id}` WebSocket streams real-time log lines from the
EventBus to the browser.
## 6. Coexistence with legacy Bash sorcery
Both tools can run side-by-side indefinitely:
| Concern | Bash sorcery | Sorcery-Go |
|---------|--------------|------------|
| Binary | `/usr/sbin/cast` | `/usr/local/sbin/sorcery-go` |
| State | `/var/lib/sorcery/` | `/var/lib/sorcery-go/` |
| Spool | `/var/spool/sorcery/` | `/var/spool/sorcery-go/` |
| Grimoire | `/var/lib/sorcery/codex/grimoire` (shared, read-only) | same |
| Spell format | Bash scripts | same (we source them via bash) |
The grimoire is read-only for both tools — neither modifies spell files.
You can switch between them freely:
```bash
sudo cast wget # legacy Bash cast
sudo sorcery-go cast wget # new Go cast
```
The Go binary's state (Tomb, Tablet, Journal) is completely separate, so
a broken Go cast never affects the Bash install and vice versa.
## 7. Uninstall
```bash
sudo make uninstall # removes /usr/local/sbin/sorcery-go
sudo rm -rf /var/lib/sorcery-go # removes all Go state (Tomb, Tablet, Journal)
sudo rm -rf /var/spool/sorcery-go # removes cached source tarballs
```
The legacy Bash sorcery is untouched.
## Troubleshooting
### "sandbox: overlay mount failed"
You're not root, or your kernel lacks `CONFIG_OVERLAY_FS`. The pipeline
falls back to a plain-dir mode automatically — builds still work, they're
just slightly slower (manifest is collected by diffing before/after).
### "summon: hash mismatch"
The `SOURCE_HASH` in the spell's DETAILS doesn't match what's currently
being served at the `SOURCE_URL`. Upstream may have re-rolled the tarball.
Re-compute the hash with `sha512sum wget-1.21.4.tar.gz` and update DETAILS.
### "pgp: no GOODSIG in gpg output"
The DETAILS file is signed but the signing key isn't in your keyring.
Either import the key (`gpg --import <key>`) or unset
`SORCERY_GO_PGP_KEYRING` to disable PGP attestation.
### "legal: license X is blacklisted"
Your active posture blocks the spell's license. Switch posture:
```bash
sudo SORCERY_GO_POSTURE=lawless sorcery-go cast <spell>
```

# Sorcery-Go Documentation Standard (SGDS)
Every module, spell, or Essence in the Coven must follow this standard.
## Engine
- **Engine:** Go 1.21+ (statically linked)
- **Storage:** Content-Addressable Essence (.ess) — Merkle trees
- **Security:** eBPF Tomb Guard + cgroup filters + network firewall isolation
- **Orchestration:** Cockpit-integrated WebUI (Coven Mirror)
- **Cluster:** Firewall-isolated Ley-Lines, Fester-scheduled distributed builds
## Essence Specification
Every Essence bundle documents its Merkle root and layering order:
```markdown
# Essence: openssl-3.2.1
## Cryptography
- **Root Hash:** `sha256:9f4e2a8b...`
- **Signature:** `ed25519:...`
- **Signer:** Build-Master-01
## Composition
- **Parent Essence:** `base-glibc-2.35.ess`
- **Added Blobs:** 142
- **Deduplication Ratio:** 84.2%
## Linkage
- **Type:** `ELF-Dynamic`
- **Libc:** `glibc-2.35`
- **Portable:** `False`
```
## Deployment Manifest (LXC Target)
Used by the deployment manager to hydrate a container:
```markdown
# Deployment: web-farm-alpha
## Infrastructure
- **Target Engine:** systemd / OpenRC
- **Firewall:** OPNsense (active) + OpenSnitch / Portmaster (per-process)
- **Isolation:** eBPF Tomb Guard (in-kernel enforcement)
## Hydration Recipe
1. Load `core-runtime.ess`
2. Inject `security-headers.ess`
3. Bind `/var/lib/sorcery-go/essences` (read-only)
```
## Compliance Profiles
| Profile | Posture | Use Case |
|-----------------|--------------|------------------------------|
| `strict_copyleft` | FSF/GNU | Pure free-software fleet |
| `corporate_lite` | MIT/Apache | Risk-averse enterprise |
| `lawless` | Wildcard | Sovereign — no license restrictions |
## Module Documentation
Every package under `pkg/` opens with a Go doc comment that explains:
1. The package's role in the Coven.
2. The public API (key types and methods).
3. Any side effects (disk I/O, network, kernel state).
See `pkg/dag/dag.go`, `pkg/tomb/storage.go`, and `pkg/toolchain/btc.go` for
examples.

# Sorcery-Go Quick Start
## 1. Bootstrap
```bash
./scripts/bootstrap.sh
make build
sudo make caps
./build/sorcery init
```
## 2. The Primary Rituals
| Ritual | Command | Effect |
|----------|--------------------------------------|-------------------------------------|
| Cast | `sorcery cast <spell>` | Forge an Essence in the Cauldron |
| Reanimate| `sorcery reanimate <ess> --sanctum <id>` | Deploy an Essence from the Tomb |
| Gaze | `sorcery gaze install <spell>` | Inspect every file owned by an Essence |
| Ward | `sorcery ward status` | Check firewall and alarm status |
| Banish | `sorcery dispel <spell>` | Surgical removal from a Sanctum |
## 3. Cast Flags
| Flag | Effect |
|-------------------------|----------------------------------------------|
| `--target <arch>` | Cross-compile for x86_64, aarch64, or any BTC target |
| `--static` | Produce a portable static ELF (musl) |
| `-r` / `--reconfigure` | Force ICE y/n prompts even if Tablet has answers |
| `-d` / `--default` | Accept all defaults (HPC-friendly) |
| `-m` / `--matrix` | Build across all maintained arches simultaneously |
## 4. Coven Management
```bash
sorcery coven join <master-ip> # Add a new Sanctum to the Coven
sorcery coven pulse # Live heartbeat of every node
sorcery coven drain <node-id> # Migrate builds off a node for maintenance
sorcery coven list # Show all known Sanctums
```
Distributed build scheduling is delegated to Fester when a cluster is active.
## 5. Tomb (Binary Storage)
```bash
sorcery tomb list # Show every Essence in the Tomb
sorcery tomb verify --all # Warding bit-rot check
sorcery tomb purge # Garbage-collect unreferenced blobs
```
## 6. Warding (Security)
```bash
sorcery ward status # Active alarms + quarantined nodes
sorcery ward banish <node-id> # Freeze a Sanctum and log the banishment
```
Transport security is handled at the network firewall layer (OPNsense / IPFire).
There are no certificates or key material to manage.
## 7. Legal Sentinel
```bash
sorcery legal audit # Scan fleet for license violations
sorcery legal sbom <essence_id> # CycloneDX SBOM on stdout
sorcery legal set-posture lawless # strict_copyleft | corporate_lite | lawless
sorcery legal credits --out ./DIR # Collect every COPYING / LICENSE file
```
## 8. Coven Mirror (WebUI)
```bash
sorcery web --port 8080
# -> http://localhost:8080
```
Tabs: Grimoire, Tomb, Pulse, Sanctum, Portable Bin, Compliance.
## 9. Portable Tool Bin
```bash
# Forge a static, portable version of a tool
sorcery cast procps --static --target aarch64 --essence-out ./portable-top.ess
# Generate the curated Emergency Kit
cauldron emergency-kit --bundle ./emergency.svb
```
## 10. First Flight (Genesis Ritual)
```bash
./scripts/forge_first_sanctum.sh
```
This automates the cast, seal, hydrate, and verify loop with a static busybox
Essence. If it succeeds, the Cauldron, Tomb, and Warding are operational.

# The Ritual of Casting
A guide for the Sovereign Admin — from the veteran shell-scripter to the new
hire. This ritual transforms raw source code into a hardened, portable Essence.
## I. The Gathering (Dependency and License Check)
Before the fires are lit, the Cauldron and the Warding must agree on the
ingredients.
- **The Ancestry** — the engine scans `DETAILS` and `DEPENDS`. If a library
is missing, it is queued for forging.
- **The Legal Seal** — the Legal Sentinel checks the spell's license against
the active posture (strict_copyleft, corporate_lite, or lawless). If you try
to cast a blacklisted AGPL tool under `corporate_lite`, the Warding
blocks the build before it starts.
## II. The Incantation (The Interactive y/n ICE)
The admin interacts with the Tablet. This is where you define the Soul of the
binary.
- **The Query** — the CLI asks: `? [wget] Enable SSL support? (y/n) [default: y]:`
- **The Memory** — your choice is saved in BoltDB. Next time you cast, the
Tablet remembers — ensuring your configuration is consistent across the
entire fleet.
Three interfaces share the same Tablet, so an answer you give in the WebUI
appears the next time you cast from the CLI.
## III. The Forging (Cross-Compilation and Toolchains)
- **The Cauldron** uses cross-toolchains — a powerful x86_64 Master node can
forge an AArch64 binary for an ARM edge-device, or an ARM binary for a
Raspberry Pi using a BTC.sh-forged toolchain.
- **The Coven** — if the build is massive (like glibc) and Fester is active,
the Master shards the work across cluster nodes via DAG-driven scheduling.
## IV. The Sealing (Merkle Hashing and the Tomb)
Once the binary is forged, it is sealed so it can never be corrupted.
- **The Merkle Tree** — every file in the build is hashed. These hashes are
combined into one final root hash (the `essence_id`).
- **The Tomb** — the Essence is stored under `/var/lib/sorcery-go/tomb/blobs/`.
It is now immutable. If a single bit changes, the Warding detects it
instantly and refuses Reanimation.
## V. The Hydration (Container Deployment)
Now the Essence must be brought to life inside a Sanctum.
- **Reflink / Hardlink** — instead of copying files, the engine links the
Essence into the container's filesystem. On btrfs or xfs this is zero-copy.
- **Atomic Swap** — when you upgrade a tool, the engine points the link to
the new Essence hash. To the container it looks like a standard update,
but it happens in under a second.
## Admin Troubleshooting — The Gaze
When a ritual fails or a node acts strangely, use the Gaze to see the truth:
```bash
gaze install <spell> # "Show me every file this spell owns."
gaze tablet <spell> # "Show me exactly how this was configured."
gaze essence <hash> # "Which spell + flags produced this blob?"
gaze whereis /usr/bin/wget # "Who owns this file?"
sorcery ward status # "Is the Warding active? Any tainted Essences?"
```
## Vocabulary Cross-Reference
| Traditional Term | Sovereign Term | Plain English |
|--------------------|--------------------|------------------------------------------------------------|
| Package | Essence | A cryptographically sealed folder of files |
| Build Server | The Coven | A team of servers compiling code together |
| Firewall / Audit | The Warding | The layer that stops bad code and illegal licenses |
| Symlink / Mount | Hydration | Attaching a tool to a container so it can run |
| State DB | The Tablet | The journal of every y/n answer you have ever given |
| Binary cache | The Tomb | The content-addressable storage where Essences rest |
| Container / Node | The Sanctum | The isolated runtime where software executes |

# Sorcery-Go Security — The Warding
## 1. Defence in Depth
| Layer | Responsibility | Tooling |
|-------|-------------------------------------|--------------------------------------------------|
| 1 | In-kernel MAC enforcement | eBPF LSM (Tomb Guard) |
| 2 | Device + network control | eBPF cgroup filters |
| 3 | Network firewall between nodes | OPNsense / IPFire (Coven isolation) |
| 4 | Per-process network filtering | OpenSnitch or Portmaster (selectable per node) |
| 5 | Content-addressing and verification | Merkle root + per-blob SHA-256 hashing |
| 6 | Quarantine and containment | cgroup freezer, multi-runtime (LXC, Podman, Firecracker, baremetal) |
## 2. Firewall-First Security Model
Sorcery-Go delegates all transport security to the network boundary. A dedicated
firewall appliance (OPNsense or IPFire) isolates the Coven so that only
authorized Sanctum IPs may exchange Essence traffic. This eliminates the need for
application-layer certificate management entirely.
### Recommended Firewall Rules
| Direction | Source | Destination | Port | Action |
|------------|----------------|----------------|----------------|--------|
| Intra-Coven| Sanctum subnet | Sanctum subnet | 8080 (sorcery) | Allow |
| Intra-Coven| Sanctum subnet | Sanctum subnet | 8181 (Fester) | Allow |
| Intra-Coven| Sanctum subnet | Sanctum subnet | 9090 (Cockpit) | Allow |
| Outbound | Master Sanctum | Artifact cache | 8181 | Allow |
| Default | Any | Any | Any | Deny |
There is no built-in TLS, mTLS, or application-layer encryption in the
codebase. All `crypto/rand`, `crypto/tls`, and `crypto/x509` code paths have
been removed. Task IDs are generated deterministically using atomic counters
and nanosecond timestamps.
## 3. eBPF Tomb Guard — The Immutable Vault
Every runtime environment — LXC, Podman, Firecracker, or baremetal — is
enforced by the same eBPF LSM program (`sorcery-tomb-guard`). Unlike
user-space profiles, eBPF provides in-kernel enforcement that works uniformly
across all runtimes without per-runtime profile syntax.
The Tomb Guard BPF program attaches to `file_open`, `path_link`, and
`path_unlink` hooks and applies a single policy:
- **Read-only** access to `/var/lib/sorcery-go/essences/` and its contents.
- **Deny** all writes, hardlinks, symlinks, and deletes under the Tomb.
- **Allow** read access to `/var/lib/sorcery-go/state/state.db`.
If a compromised container or process attempts to poison the Tomb, the eBPF
LSM blocks the operation in-kernel and the Warding raises an Illegal Write
Attempt alarm that is rendered on the Cockpit Threat Map.
## 4. Network Gatekeepers
The Coven supports either OpenSnitch or Portmaster (selectable per node,
never both). The Sorcery-Go engine auto-detects which is active and injects
the appropriate rules.
### OpenSnitch Rule
```json
{
"name": "Sorcery-Essence-Sync",
"enabled": true,
"action": "allow",
"duration": "always",
"operator": {
"type": "list",
"data": [
{ "type": "simple", "operand": "process", "data": "/usr/local/bin/sorcery-go" },
{ "type": "regexp", "operand": "dest_host", "data": "registry\\.local" }
]
}
}
```
### Portmaster Integration
Defines the Sorcery-Go process as a Trusted System Utility with a scoped
network boundary — only the stream to the Master Essence Registry is permitted;
all other egress from the build sandbox is dropped.
## 5. Emergency Banishment
If a Worker is physically stolen or compromised:
```bash
sorcery-go ward banish <node-id>
```
This freezes the offending Sanctum via cgroup/runtime freeze and records
the banishment in the Warding alarm log. The firewall rule for that node
should also be removed or blocked at the network boundary.
## 6. Quarantine Logic
When the Warding detects a high-severity threat (binary signature mismatch
in the Tomb), it can automatically:
1. Freeze the offending process or container via cgroups (`cgroup.freeze`)
— works identically across LXC, Podman, Firecracker, and baremetal.
2. Sever the Essence links to prevent memory-based exploit spread.
3. Broadcast the alarm to every other Sanctum.
4. Highlight the node red on the Cockpit Threat Map.
## 7. First-Boot Hardening Test
```go
// pkg/warding/audit_test.go
func TestFirstBootHardening(t *testing.T) {
// eBPF Tomb Guard must block writes to /var/lib/sorcery-go/essences/
err := os.WriteFile("/var/lib/sorcery-go/essences/malicious_hash",
[]byte("void"), 0644)
if err == nil {
t.Error("SECURITY FAILURE: eBPF Tomb Guard allowed write to Tomb!")
}
}
```
Run this after every deploy to confirm the Warding is active.
## 8. Security Pulse Indicator
The Cockpit WebUI shows a single traffic-light indicator:
- Green — eBPF Tomb Guard active; OpenSnitch/Portmaster reporting zero leaks
- Yellow — A toolchain is currently being validated in the Lab
- Red — Hash mismatch or unauthorized write detected — Automatic Quarantine engaged

# Spell Specification (SPELL.md)
Every spell in the Grimoire is a directory containing Bash scripts:
```
grimoire/
└── libs/
└── openssl/
├── DETAILS # Metadata: SPELL, VERSION, SOURCE_URL, etc.
├── DEPENDS # Direct dependencies + sub-depends
├── BUILD # Compilation script (runs inside the sandbox)
├── CONFIGURE # Interactive y/n queries (consumed by ICE)
├── PRE_BUILD # Optional pre-build steps
└── INSTALL # Optional install override
```
## DETAILS Fields
| Field | Required | Example |
|-------|----------|---------|
| `SPELL` | yes | `openssl` |
| `VERSION` | yes | `3.2.1` |
| `SOURCE` | yes | `${SPELL}-${VERSION}.tar.gz` |
| `SOURCE_URL[0]` | yes | `https://www.openssl.org/source/...` |
| `SOURCE_HASH` | yes | `sha512:abc123...` |
| `SOURCE_DIRECTORY` | yes | `${BUILD_DIRECTORY}/${SPELL}-${VERSION}` |
| `WEB_SITE` | no | `https://www.openssl.org/` |
| `ENTERED` | no | `20260317` |
| `LICENSE[0]` | yes | `Apache-2.0` |
| `SHORT` | yes | "The Open Source toolkit for SSL/TLS" |
## DEPENDS Format
```bash
# Runtime dependency
depends glibc ""
# Build-only dependency
depends pkg-config "" build
# Optional dependency (toggled via ICE)
depends zlib "--with-zlib" optional
# Sub-dependency: requires openssl to be built with ssl3
sub_depends openssl ssl3
```
## CONFIGURE Format
The Interactive Configuration Engine (ICE) intercepts `config_query` calls:
```bash
config_query OPENSSL_SSL3 "Enable SSLv3 (insecure)?" n
config_query OPENSSL_IPV6 "Enable IPv6 support?" y
config_query OPENSSL_ASM "Use assembly optimisations?" y
```
Answers are persisted in the Tablet (BoltDB). Subsequent casts reuse the
answers unless `--reconfigure` is passed.
## BUILD Script
The BUILD script runs inside the OverlayFS sandbox. Standard pattern:
```bash
#!/bin/bash
cd "$SOURCE_DIRECTORY" &&
./configure --prefix=/usr "$@" &&
make &&
make install
```
The sandbox's `upper` directory captures every file `make install` writes —
this becomes the Essence manifest. No `installwatch` / `LD_PRELOAD` needed.
## Spell Generation via Quill
```bash
quill new zlib
# → launches the interview wizard
# → emits DETAILS, DEPENDS, BUILD, CONFIGURE
# → auto-hashes the upstream source via the "Smart Quill" mode
```
The WebUI provides a modal form that drives the same `quill.GenerateSpell`
code path so CLI and WebUI produce identical output.

# Toolchain Specification
## 1. Sovereign Toolchains
The Coven does not download pre-built GCC/LLVM binaries. Each admin maintains
their own toolchains, or forges them with BTC.sh. Toolchains are stored under
`/opt/sorcery-go/toolchains/<triple>/` (manual) or `/opt/BTC/<SYS_LABEL>/`
(BTC.sh golden images). The Sandbox `AttachToolchain` bind-mounts the requested
toolchain read-only into the build namespace.
## 2. BTC.sh Integration
Sorcery-Go integrates with BTC.sh for cross-compilation across 19 target
architectures. The `pkg/toolchain/btc.go` module probes for golden images,
parses their manifest JSON sidecars, and configures the build environment.
### Supported Targets
| Family | Targets |
|------------------|----------------------------------------------------------------|
| Intel HEDT/Server| haswell, haswell-ep, skylake, skylake-x, skylake-server |
| AMD Ryzen/EPYC | znver1, znver2, znver3, znver4 |
| AMD APU | apu-zn1, apu-zn2, apu-zn3, apu-zn4 |
| Intel Atom | atom-silvermont, atom-goldmont, atom-tremont, atom-sierraforest|
| Embedded | mipselr2, armv7, tilegx |
### ISA Tiers
| ISA Tier | Flags |
|----------|-----------------------------------------------------|
| AVX512 | `-mavx512f -mavx512dq -mavx512vl -mavx512bw` |
| AVX2 | `-mavx2` |
| SSE4_2 | `-msse4.2` |
| NEON | `-mfpu=neon -mfloat-abi=hard` |
| MIPS32 | (per-target architecture) |
| TILE | (per-target architecture) |
## 3. Required Specs (Manual Toolchains)
```markdown
# Toolchain: aarch64-linux-musl
## Specifications
- **Version:** GCC 15.1.0 / Binutils 2.44
- **C Library:** musl 1.2.5
- **Optimizations:** `-O3 -flto -march=armv8-a`
- **Hardening:** `-fstack-protector-all -pie -fPIE -D_FORTIFY_SOURCE=2`
## Essence Compatibility
- **Min Engine Version:** 1.0.2
- **Supported Targets:** Generic-ARM64, Pine64, RPi5
## Validation
- **Validator Pass:** true
- **Smoke Test:** Hello-World compiled, ldd reports "not a dynamic executable"
- **Has SSP:** true
- **Has PIE:** true
```
## 4. Validation Pipeline
Every toolchain must pass `pkg/toolchain.Validate` before it can forge
production Essences:
| Check | Method |
|------------------------|---------------------------------------------------|
| Arch detection | Parse `gcc -v` output for triple |
| Stack Smashing Protection | Inspect for `--enable-default-ssp` |
| PIE | Inspect for `--enable-default-pie` |
| LTO | Inspect for `--with-default-libstdcxx-abi=lto` |
| Smoke test | Compile `int main(){}` with `-fstack-protector-all -pie` |
If `Validate()` returns `Report.Passed = false`, the Cauldron refuses to
attach the toolchain and the WebUI flags it in the Toolchain Lab view.
## 5. Per-Spell Overrides
Some spells (kernel, glibc) need a different toolchain than the default.
The WebUI lets the admin attach an override per spell:
```yaml
spell: linux
toolchain_override: /opt/sorcery-go/toolchains/x86_64-linux-gnu-gcc-14
```
## 6. Fleet Re-Forge
When a toolchain is updated, the WebUI's Fleet Re-Forge button flags
every Essence built with the old version and re-queues them for the
Cauldron. This ensures the entire Coven runs code compiled with the latest
toolchain.

# Firecracker MicroVM Configuration for a Sorcery-Go Sanctum
# File: Referenced by pkg/runtime/firecracker.go
#
# Firecracker provides VM-level isolation — the strongest isolation
# option available. Each sanctum runs in its own microVM with a
# dedicated kernel and rootfs.
#
# Unlike LXC/Podman, Firecracker does NOT use cgroups on the host.
# The eBPF cgroup filters do not apply inside the guest. However,
# the eBPF Tomb Guard LSM hook still protects the HOST's Tomb from
# any process including the Firecracker VMM itself.
#
# Network isolation is handled by:
# 1. Firecracker jailer (chroot + seccomp)
# 2. Per-VM TAP devices with bridge filtering
# 3. Host-level eBPF network filters on the bridge
#
# Required files:
# - SORCERY_GO_FIRECRACKER_KERNEL: path to vmlinux (host kernel image)
# - Root drive: qcow2 or raw rootfs image
# Memory: 256MB default (sufficient for build workloads)
# VCPUs: 1 (scale up for parallel builds)
# Boot: serial console only (no graphical)
# Kernel args: console=ttyS0 reboot=k panic=1 pci=off
# Example Firecracker API configuration:
# {
# "boot-source": {

// Package cas provides a content-addressable store client for the
// sorcery-go ↔ Fester shared artifact cache.
//
// After BundleSovereign produces a .svb file, the Cauldron can push it to
// the shared CAS via PushArtifact. Fester's DAG executor checks the CAS
// before dispatching builds — if the artifact already exists (any runtime,
// any node), the build is skipped entirely.
//
// The CAS is keyed by SHA-256 of the content. This means:
// - An artifact built inside LXC on Node A is instantly available to
// a Firecracker microVM on Node B.
// - A .svb bundle produced by sorcery-go on the master node is
// immediately available to all Fester workers.
// - The same library compiled with the same toolchain on different
// runtimes will deduplicate if the output matches.
//
// API contract (mirrors Fester's /api/cas/ endpoints):
//
// PUT /api/cas/{sha256} — store an artifact
// GET /api/cas/{sha256} — retrieve an artifact (streamed)
// HEAD /api/cas/{sha256} — check existence
// DELETE /api/cas/{sha256} — remove an artifact
// GET /api/cas/ — list all artifacts
// GET /api/cas/stats — cache statistics
//
// Usage:
//
// client := cas.NewClient(festerURL)
//
// // After BundleSovereign:
// sha, err := client.PushFile(ctx, "/path/to/output.svb", cas.ArtifactMeta{
// Source: "output.svb",
// Target: "x86_64-linux-gnu",
// Runtime: "podman",

// Firecracker runtime adapter for Sorcery-Go Sanctums.

// Firecracker is an AWS open-source microVM that provides strong VM-level

// 5. Start the instance
