Standard production layout: the OKR app (was nested under AINative_OKR_CASAN5/) is now
the repository root. No more wrapper directory.
- Promote AINative_OKR_CASAN5/* -> repo root (backend/ frontend/ packages/ apps/
.specify/ docs/ infra/ nginx/ scripts/ + configs). Merge tool dirs: .gitea (kept the
active deploy ci.yml, added harness-ci.yml + runbooks), .claude (agents/commands +
launch.json), .github moved up.
- Remove redundant: 00_SUBMISSION_PACKAGE, scattered root notes (FPT_CASAN_Full.md,
tu-tuong-casan.md, casan-tu-sinh..., casan_harness_assessment.md, source-review...,
README_CASAN5_REFINED.md), casan-next-plans/ and optimize-docs/ (competition/planning
artifacts — roadmap + design history preserved in git log / commit messages).
- Update all references to the old layout:
- .gitea/workflows/{ci,harness-ci}.yml, .github/workflows/{ci,deploy}.yml:
working-directory .; drop AINative_OKR_CASAN5/ prefix; .specify/{tests,scripts}
-> packages/casan-harness/... (.specify/logs state kept)
- .claude/launch.json, .gitea/*-runbook.md: path prefixes
- CLAUDE.md, README.md: docs/input -> apps/okr/domain/input
- policy-bundle.yaml: 8 policy paths -> packages/casan-harness/...; manifest re-signed
- secrets-scan.sh: fixture excludes -> new package/domain paths.
Full gate from the new root: PASS=64 FAIL=0 SKIP=3.

# CASAN Track C-MVP — Tool authorization / ACTION gating (C1, V17).
|
|
#
|
|
# tool-registry-gate.sh authorizes by tool NAME + agent. This complements it by
|
|
# inspecting the ACTION itself — the command to run and the files it would
|
|
# write — because a legitimately-named tool can still attempt an illegitimate
|
|
# action (overwrite .env, curl|bash, rm -rf /, exfiltrate to an unknown host).
|
|
#
|
|
# Outcome model (per Plan-07 C0): ALLOW | WARN | REQUIRE_APPROVAL | BLOCK.
|
|
# BLOCK sensitive-file write, destructive/remote-exec command -> exit 2
|
|
# REQUIRE_APPROVAL network egress, dependency install -> exit 3
|
|
# (becomes ALLOW+audit when CASAN_ACTION_APPROVER is set)
|
|
# WARN noteworthy but permitted -> exit 0 (logged)
|
|
# ALLOW ordinary action -> exit 0
|
|
#
|
|
# Usage:
|
|
# action-gate.sh --command "<cmd>" [--write <path> ...]
|
|
# action-gate.sh -- <cmd> [args...]
|
|
#
|
|
# BLOCK is never overridable. REQUIRE_APPROVAL clears only with an explicit
|
|
# approver identity (audited) — approval is never silent.
