Organize CASAN as a reusable source hub with SPLIT releases so downstream adopts only the level it needs (packaging/levels.json is the single source of truth). Implemented now: - Level 1 Core: bin/casan CLI (run/gate/test/verify/reuse/dashboard) + VERSION. - Level 2 DevKit: packages/casan-devkit (install.sh, Dockerfile.harness, templates: project scaffold, domain-pack, gitea-workflow). - scripts/package-release.sh core|devkit|platform|all-in-one-demo — builds split bundles into dist/ (BUNDLE-MANIFEST + SHA256SUMS); platform is stamped PREVIEW/INCOMPLETE; enterprise (future) is REFUSED (exit 3, no fake-complete package). Bundles verified: extract → bin/casan works, deterministic + domain suites pass, casan reuse VALID. - docs/packaging: CASAN_PACKAGING_PLAN + ADOPTION + CI + DOMAIN_PACK + GITEA_PACKAGE + DOCKER. Structure + docs only: - Level 3 packages/casan-platform (dashboard exists; control-panel/viewers pending). - Level 4 packages/casan-enterprise (RBAC/tenant/KMS/WORM/approval exist in core; governed console pending). No Chat Console/RBAC-console/tenant-console/model-mgmt built in this task. Harness change (enables extracted bundles to self-resolve): casan-paths.sh + the Python project_root() walk-ups now accept a second root marker `packages/casan-harness` in addition to `.specify`, so a freshly-unpacked core/devkit/demo bundle (no `.specify` yet) roots correctly and creates state on first run. In an adopted repo `.specify` still matches first. policy-bundle.yaml paths corrected to packages/casan-harness (re-signed). Full gate 64/0/3.

CASAN Docker Guide
Run the CASAN governance harness as a container against any mounted repo — no install into the target project.
Image: casan-harness (Level 1/2)
Dockerfile: packages/casan-devkit/Dockerfile.harness.
Minimal Debian + bash + python3 + openssl + git. Ships the core harness + bin/casan.
Build
V=$(cat VERSION)
docker build -f packages/casan-devkit/Dockerfile.harness -t casan-harness:$V .
Run the gate on a project
docker run --rm -v "$PWD":/workspace -w /workspace casan-harness:1.0.0 gate
# (ENTRYPOINT is `casan`, so the CMD is a casan subcommand)
docker run --rm -v "$PWD":/workspace casan-harness:1.0.0 reuse
docker run --rm -v "$PWD":/workspace casan-harness:1.0.0 \
run in.txt out.txt my_step -- echo hello
The harness inside the image lives at /opt/casan (CASAN_HARNESS_ROOT preset); your
project is mounted at /workspace. Domain data is read from the mounted repo
(apps/<project>/domain via CASAN_DOMAIN_ROOT).
With a domain root
docker run --rm -v "$PWD":/workspace -w /workspace \
-e CASAN_DOMAIN_ROOT=apps/ticketing/domain casan-harness:1.0.0 gate
Notes
- State (
.specify/logs, audit) is written under/workspace(your mounted repo), so it persists on the host and is inspectable after the run. - Enforced mode: add
-e CASAN_PROFILE=prod(or-e CASAN_VERIFY_STRICT=1) to make missing signatures fail-closed. - No app runtime: this image runs the harness, not the OKR app. For the app, use the
project's own
Dockerfile.backend/Dockerfile.frontend+docker-compose.prod.yml.
