Resolve every root by marker walk-up instead of a fixed depth that only lands on the app via the .specify compat symlink, so the harness runs correctly when invoked by its real packages/casan-harness path — proven by a full gate run via that path: 64/0/0. - 95 scripts/tests: PROJECT_ROOT/ROOT "$SCRIPT_DIR/../.."-style computations -> $CASAN_APP_ROOT. - 6 leaf scripts (infra-lab, context-validate, secrets-scan, path-guard, toolchain-verify, phase2-sourcegen) now source casan-paths + use CASAN_APP_ROOT. - run-casan4: source casan-paths as a package sibling (facade-independent), PROJECT_ROOT=CASAN_APP_ROOT. - 8 Python files: project_root()/REPO_ROOT/bundle_root walk UP for the .specify marker (control-plane-settings, loop_common, model-call, context-compress, test-integrity, bundle-integrity, traceability-matrix; generate-* fixed earlier). - evidence-pack-build.py + traceability-matrix.py: domain refs -> apps/okr/domain (input/, corpus/redteam-vectors.jsonl, traceability-map.json). - ci-harness-gate.sh: export CASAN_TESTS_DIR/CASAN_TEST_MANIFEST/CASAN_BUNDLE_ROOT so the integrity Python resolves via the harness root regardless of invocation path; ROOT=CASAN_APP_ROOT. - Remove the domain compat symlinks from packages/casan-harness/security (redteam-corpus, redteam-vectors, benign-corpus) — packages now holds NO domain data. Both invocation paths pass (compat facade still present): .specify/... and packages/... Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# CASAN Plan-16 SEC-02 (H-02) — no local key auto-generation in enforced mode.
|
|
#
|
|
# The tamper-evidence of the audit chain rests on the head signature. If the
|
|
# signer auto-generates a private key next to the data (as dev convenience does),
|
|
# then any actor who can write the log can also mint a key and re-sign a forged
|
|
# head. In enforced mode the signer must NOT auto-generate — the key is provisioned
|
|
# out-of-band (KMS/HSM). This proves:
|
|
# * permissive mode still auto-generates a local key (dev convenience),
|
|
# * enforced mode does NOT create a key when none is provisioned, and the
|
|
# resulting unsigned head then FAILS strict verification (fail-closed).
|
|
#
|
|
# Deterministic; hermetic (temp key dir + backup/restore of audit + gov dirs).
