thanhnvandClaude Opus 4.8 8c20cfde9f feat(packaging): level-based source hub — Core + DevKit packaging, Platform/Enterprise scaffold
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 Domain Pack Guide

A Domain Pack is the per-project data the harness needs to govern YOUR domain. It lives at apps/<project>/domain/ and is selected via CASAN_DOMAIN_ROOT. The harness code (packages/casan-harness/) never contains domain data — this is what makes it reusable.

Scaffold template: packages/casan-devkit/templates/domain-pack/.

Layout

apps/<project>/domain/
├── domain-pack.yaml           # manifest describing this pack
├── input/
│   ├── requirement.md         # FR-xx table drives the traceability gate
│   └── architecture.md        # optional tech-stack/context
├── golden-runs/
│   └── <artifact>.golden.txt  # baseline for drift detection (H7)
├── corpus/
│   ├── redteam-corpus.jsonl   # attack vectors (H4 recall) — one JSON per line
│   ├── redteam-vectors.jsonl  # vectors for benign-fp-report / redteam metrics
│   └── benign-corpus/*.txt    # benign samples (H4 false-positive budget)
└── traceability-map.json      # FR-xx → code files + test files (+ optional symbols/lines)

Each piece

  • input/requirement.md — must contain a | FR-xx | ... | table. The traceability gate (Plan-10) requires every FR-xx to map to ≥1 existing code file and ≥1 test file. No secrets/PII (the H4 input scan blocks them).
  • golden-runs/ — a canonical "good" artifact per pipeline output. drift-detect compares a run against it; similarity 1.0 = no drift. Real drift detection is proven separately.
  • corpus/ — red-team attack vectors (scored for H4 recall) + a benign corpus (bounds the false-positive rate). Domain-specific injections make the H4 score meaningful.
  • traceability-map.json — {"FR-01": {"name": "...", "code": ["backend/src/...", {"file":"...","symbols":["Foo"],"lines":[12]}], "tests": ["..."]}}. Symbol/line refs are optional but tighten the gate.
  • domain-pack.yaml — documents the above + optional threshold overrides.

Wire it up

export CASAN_DOMAIN_ROOT=apps/<project>/domain
bin/casan gate                 # runs domain-dependent suites against your pack

domain_root is also recorded per-project in packages/casan-harness/level5/project-registry.json so bin/casan reuse can prove multi-project reuse.

Reference example

The OKR app's own pack is the worked example: apps/okr/domain/ (golden-runs, corpus, input, traceability-map). Copy its shape for your domain.

Toward Plan-12 (Domain Pack SDK)

Today a pack is a directory + CASAN_DOMAIN_ROOT. Plan-12 will make it fully declarative (register a pack by manifest, no manual wiring). The domain-pack.yaml here is the seed of that manifest.
