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-17 Track 5 — Meta-loop (self-improving loop policy).
|
|
#
|
|
# Proves:
|
|
# * propose is dry-run (emits proposals, writes nothing to the CP store),
|
|
# * apply enforces Separation of Duties (proposer == approver -> DENY),
|
|
# * apply requires an approval (no approval -> DENY),
|
|
# * a loosen proposal above the org hard cap is refused (17.19),
|
|
# * an approved loosen is applied via the governed store AND actually changes the
|
|
# governor's effective ceiling (governed override is real, not paper),
|
|
# * rollback via the governed store reverts the governor's behaviour,
|
|
# * the CP audit chain stays intact,
|
|
# * no repo / home pollution (sandboxed state, store, keys).
|
|
#
|
|
# Deterministic; hermetic; dev profile keeps the backward-compatible approval gate.
