Claude Opus 5	3ee023017b	fix(analytics): move the DuckDB live suite out of tests/integration, and add the BI docs ... CI's integration job failed, and it failed CORRECTLY. That job provides a live OpenSearch and a live ClickHouse and then asserts that nothing in tests/integration/ skipped, on the stated principle that "a skipped suite must never masquerade as a green integration gate". The DuckDB suite needs a Python interpreter that job does not provide, so it skipped, and the guard fired — the first suite in that directory ever to skip there. Moving the file to tests/duckdb/ respects the guard rather than weakening it. Loosening it to tolerate skips would have traded a real gate for one green job, which is the trade this estate keeps regretting. The suite still runs, still fails rather than skipping when DUCKDB_PYTHON is set and DuckDB is broken, and is still pinned by the committed evidence. Also fixed: "does NOT ship the Iceberg table" asserted against the FILESYSTEM when the claim is about what is COMMITTED. The live suite rebuilds that table locally, so the assertion failed whenever both suites ran in one pass — it was testing the wrong thing rather than catching a real problem. It now asserts against `git ls-files`, and also asserts the parquet/csv fixtures ARE tracked, so a version that stopped shipping any fixture would fail too. docs/analytics/BI_QUERY_METRIC_QUALITY.md is organised around what is PROVEN and what is NOT, because the second list is the one that gets dropped. It records the five findings and the six open items, including that BI-P029's MetricFlow was never executed and that BI-P021's budget is a bound rather than a hard cap (measured 130x overshoot at a 100ms poll). It also reports, without changing it, a latent flaw in .gitea/workflows/ci.yml (a protected file this branch does not touch): the integration guard's second pattern `Tests [0-9]+ passed` never matches, because vitest writes that summary with ANSI colour codes between the words. The guard is therefore STRICTER than it reads — "any skip fails" rather than "skipped and nothing passed" — so nothing is currently unguarded, but the escape hatch does not work and someone will eventually be puzzled by it. 957 tests pass with ClickHouse, Postgres and DuckDB all live.

Claude Opus 5	a9ae7f25a4	feat(analytics): BI-P014 — DuckDB provider, and the measured finding that its sandbox does not work the way it looks ... BI-P014's security requirement is the whole prompt: DuckDB is a local engine with `read_csv('/etc/passwd')` built in. Two layers. LAYER 1, the mount registry: a caller names ARTIFACT IDS, never paths. The registry resolves an id, checks the artifact belongs to the caller's tenant, and realpath()s the result to confirm it is still inside the mount root once symlinks are followed. A symlink to /etc/passwd, a traversing relative path, an absolute path, and a sibling directory sharing the root's prefix (/mnt/artifacts-evil for root /mnt/artifacts) are each refused. A cross-tenant read is AUTHORIZATION_DENIED, deliberately not NOT_FOUND — an operator reading the audit trail needs to see an attempted cross-tenant read as one. LAYER 2, THE FINDING: `SET allowed_directories=[...]` ALONE IS A NO-OP. Measured on DuckDB 1.5.5. With allowed_directories set to a single mount directory and nothing else, `read_csv('/etc/passwd')` RETURNED THE FILE and an https:// URL was fetched over the network. Only when `enable_external_access = false` is ALSO set does the allow-list bind; the same reads then fail with "Permission Error: Cannot access file". `lock_configuration=true` afterwards stops a query re-opening either. So the obvious spelling of this control — set the allow-list and move on — yields a setting that appears in duckdb_settings(), looks like a sandbox, and permits everything. That is `trivy --exit-code 0` in a different costume. The bootstrap is therefore emitted as ONE unit, `assertSessionSandboxed` refuses a session missing any part of it, and the measurement itself is PINNED by a test that never skips: if someone simplifies the bootstrap, the pinned evidence (`read_etc_passwd_succeeded: true` for the naive spelling) keeps the finding attached to the build rather than to a comment that would rot. Twelve bypass attempts run against a real DuckDB with LAYER 1 REMOVED — sent straight to the engine, registry not in the picture. Zero succeeded. The counterfactual runs in the same session and is asserted: the mounted file IS readable, so "nothing succeeded" is not a sandbox that blocks everything, which would be an outage rather than a control. A locked session is then shown unable to re-open its own sandbox, all three ways. DoD, against real fixtures: Parquet aggregates correctly (SE 394.5, NO 105.5), CSV round-trips a value containing a quote, and an ICEBERG SNAPSHOT reads via iceberg_scan on an exact metadata JSON — which is not a workaround: DuckDB refuses to glob for the latest version because globbing can read uncommitted data, and an exact metadata file is what "snapshot" means. Arrow is reported UNPROVEN by `readiness()` with the reason: DuckDB's arrow extension is a network install the offline environment could not download. THREE DEFECTS IN MY OWN TESTS, found and fixed rather than tidied away: * a bypass-corpus entry was `SELECT 1 FROM (SELECT 1) t` — not an attack at all. It succeeded and was reported as a leak. A corpus entry that cannot fail is as useless as a check that cannot. Replaced with real ATTACH and COPY attempts. * the harness ran the session bootstrap outside its try block, so a statement that correctly REFUSED to re-open a locked sandbox killed the subprocess and surfaced as an unreadable "Command failed" instead of as the meaningful refusal it was. * the Iceberg fallback was `expect(evidence.iceberg ?? "unbuilt").toBeDefined()` — a check that can never fail. It let a run without the fixture ERASE the recorded Iceberg result from the evidence file while both suites stayed green. It now rebuilds the fixture when pyiceberg is available and, when it is not, asserts against the previously recorded result and marks it as carried forward. The Iceberg fixture is deliberately NOT committed: pyiceberg writes absolute paths into its metadata and Avro manifests, so a committed table resolves only on the machine that built it, and a fixture that silently fails everywhere else is worse than none. tests/fixtures/duckdb/README.md says so and gives the rebuild command; the recorded result is the artefact instead. Heavy artifacts are refused with CAPABILITY_UNAVAILABLE and pointed at N0D, per BI-P014 — silently running a 40 GB scan in the API process is how a preview engine takes down a control plane. 35 unit tests, 12 live tests.
