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 — Data-exfiltration guard (C3, V19).
|
|
#
|
|
# Content leaving the trusted boundary must not carry secrets/PII. This guard
|
|
# is the checkpoint for three egress destinations, each with its own policy:
|
|
#
|
|
# cloud — content about to be sent to a CLOUD model (OpenAI/Anthropic).
|
|
# A secret => BLOCK (fail closed); PII => masked copy emitted.
|
|
# Critical once Plan-03 wires a real cloud backend.
|
|
# audit — content about to be written to an audit/log record.
|
|
# PII/secret => masked copy emitted (BLOCK if masking impossible).
|
|
# artifact — a generated artifact about to be persisted/shared.
|
|
# Any secret / env-token => BLOCK.
|
|
#
|
|
# It reuses security-check.sh's secret/PII detection + masking (single source of
|
|
# truth) and applies the destination policy on top. Deterministic; no model call.
|
|
#
|
|
# Usage: data-exfil-guard.sh <file> <cloud|audit|artifact> [masked-output-file]
|
|
# Exit: 0 allowed (possibly masked), 2 blocked (secret at a fail-closed boundary),
|
|
# 64 usage.
