commit 3ea742f4b514576f3b70498c6f40244f593104de Author: Jeremy Anderson Date: Sun Jul 12 01:20:08 2026 -0400 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. diff --git a/.gitignore b/.gitignore new file mode 100755 index 0000000..25da1f9 --- /dev/null +++ b/.gitignore @@ -0,0 +1,24 @@ +# Build artifacts +/build/ +/bin/ +*.test + +# Local state (never commit) +/tablet/*.db +/tomb/blobs/ +/tomb/epitaphs/ +/var/ + +# Editor noise +.vscode/ +.idea/ +*.swp +*.swo +*~ + +# OS noise +.DS_Store +Thumbs.db + +# Logs +*.log diff --git a/CHANGELOG.md b/CHANGELOG.md new file mode 100755 index 0000000..3dcbfc6 --- /dev/null +++ b/CHANGELOG.md @@ -0,0 +1,104 @@ +# Changelog + +All notable changes to Sorcery-Go are documented here.

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/` +- 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.

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 `) or unset +`SORCERY_GO_PGP_KEYRING` to disable PGP attestation. + +### "legal: license X is blacklisted" +Your active posture blocks the spell's license.

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 # "Show me every file this spell owns." +gaze tablet # "Show me exactly how this was configured." +gaze essence # "Which spell + flags produced this blob?" +gaze whereis /usr/bin/wget # "Who owns this file?" +sorcery ward status # "Is the Warding active?

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 +``` + +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.

+# =============================================================================
+# Resurrect an old Source Mage chroot tarball (0.62-11 / 0.63 test branch)
+# and pull it into the modern era — then drop in sorcery-go as the new engine.
+#
+# NOTE: sorcery-go is developed by dcos.net and is NOT affiliated with
+# Source Mage GNU/Linux or sourcemage.org. This script downloads resources
+# from sourcemage.org (a separate, independent project) for convenience.
+#
+# This script encodes the 8-phase staging pipeline from the Source Mage
+# chroot path document. It is split into HOST-side subcommands (run from
+# your modern host OS) and CHROOT-side subcommands (run after you `chroot`
+# into the staged environment).
+#
+# HOST subcommands (run as root on your modern host):
+#
+#   extract      
+#                     Extract the SMGL rootfs tarball to .
+#   mount       
+#                     Bind-mount /dev /proc /sys /etc/resolv.conf into the chroot.
+#   inject-sorcery  [sorcery-tarball]
+#                     Download (or use the provided) modern sorcery engine tarball
+#                     and overlay it into the chroot's /usr and /etc.
+#   inject-kernel    [modules-dir]
+#                     Copy a modern host-built kernel + modules into the chroot.
+#                     Strips the old /boot/vmlinuz* and /lib/modules/* first.
+#   inject-sorcery-go  [sorcery-go-binary]
+#                     Drop the sorcery-go binary + state dirs into the chroot so
+#                     it coexists with legacy /usr/sbin/sorcery.
+#   fix-fstab     []
+#                     Rewrite /etc/fstab to use UUID= identifiers.
+#   enter       
+#                     chroot into the staged environment with a login shell.
+#   unmount     
+#                     Unmount the API filesystems (safe to run multiple times).
+#
+# CHROOT subcommands (run AFTER `enter`, from inside the chroot):
+#
+#   chroot-purge-grub1
+#                     Remove /boot/grub/menu.lst and dispel the legacy grub spell.
+#   chroot-cast-grub2
+#                     cast grub2 (skips gracefully if the toolchain is too old).
+#   chroot-scribe-test
+#                     Drop the dead stable grimoire and anchor scribe to the
+#                     live test branch from git://download.sourcemage.org/smgl/grimoire.git
+#   chroot-stepupgrade
+#                     Run the step-upgrade ladder: make → binutils → gcc → glibc.
+#                     This is the most fragile phase — read the docs first.
+#   chroot-init-sorcery-go
+#                     Initialise the sorcery-go state DB inside the chroot and
+#                     index the test grimoire.
