What this is

This wave's assignment was verification, not construction: read the merged code on each default branch and report, per BI prompt, DONE or MISSING. Sixteen prompts were checked across five repos. Fourteen are genuinely done, with live evidence. Two were cited as done and were not — both in 0pt, both closed here.

The two have the same shape, and it is worth naming: a sentence in a header naming a file that does not exist. Neither would survive a reader opening the path. Both survived review.

---

1 · BI-P029 — the parity test that was cited but never written

src/analytics/metrics/semantic-provider.ts named tests/integration/semantic-parity.integration.test.ts as the proof of the single BI-P029 DoD surface it claimed was closed, and providerReadiness().proven asserted that "0pt's metric compiler and an independent spec-driven renderer return the same number for the golden metric against live ClickHouse data".

That file did not exist anywhere in the repository. The citation was the evidence.

Writing it found a real bug

compileRequestToClickHouse had no notion of a metric's own filters — BI-P028's MetricSpec.filters. ResolvedMetric did not carry them and the compiler never asked.

So a metric defined as "invoiced revenue, net of credit notes, excluding internal transfers" executed as "invoiced revenue". The registry stored the filter, assertValidMetricSpec validated it, MetricFlowProvider.buildManifest emitted it into the manifest — every layer that describes the metric carried its meaning, and the only layer that runs did not.

Measured by the suite itself, not quoted from a console:

country	the metric definition	0pt returned before this change
SE	1 250	11 249
NO	400	8 177
DK	125.5	3 458.5

A plausible-looking number, ~9x too large, under the correct canonical metric id. Same family as the merged BI-P026 finding: a wrong number that reads as current is worse than a stale one, because nothing about it looks wrong.

The fix

• ResolvedMetric gains definition_filters, carried already resolved onto the physical dim_names key — the compilers stay dumb, they bind and render and never look a dimension up, and assertSafeIdentifier still applies.
• The ClickHouse compiler folds them into that metric's conditional aggregate (sumIf(value, metric = {m0} AND …)), never into the shared WHERE. One request may carry two metrics whose definitions exclude different rows; a shared predicate would silently apply one metric's meaning to the other.
• renderFilter's uniquifier becomes a string, so request filter 0 and metric filter 0_0m cannot collide in the parameter map. Two collided bindings would make one filter quietly win.
• compileRequestToSemantic carries the filters through and MetricFlowProvider.compile emits them per metric, structured — never predicate text.

Why the test is not vacuous

Two compile paths, one live ClickHouse, one golden metric from one registry version. Path A is 0pt's compiler emitting sumIf(...) with bound parameters. Path B reads only the provider's structured query object, writes its own quoting, emits sum(if(...)) with inlined literals, groups by the physical expression rather than a compiler alias, and shares no line of SQL-generation code. The suite asserts the two SQL strings differ — parity between two identical strings proves nothing. The golden metric was chosen to carry a definition filter for the same reason: every compiler agrees about a bare sum.

Adversarial check. Forcing definition_filters empty in the compiler makes Path A fail with exactly the pre-fix numbers above while Path B stays correct.

Three of BI-P029's four DoD surfaces remain not proven and providerReadiness().open still lists them: MetricFlow itself is not executed (no Python runtime is provisioned here, and METRICFLOW_PINNED_VERSION has had no licence or supply-chain review), Superset is not implemented, and the AI Analyst path has not been compared.

2 · BI-P103 — "measured baselines exist", and they did not

bi-slo.ts said "evidence/bi-p103 records the first baselines". There was no evidence/bi-p103.

The catalogue and evaluator were both real and well covered — against synthetic events. A synthetic event carries whatever duration the test author typed, so that suite proves the arithmetic and nothing about the system: it cannot tell you whether a dashboard query takes 8 ms or 8 s. BI-P103's DoD is one sentence, and it was the part not done.

tests/integration/bi-p103-slo-baseline.integration.test.ts runs 460 real queries against a live ClickHouse over a 400 000-row fact table — 120 cold dashboard queries (each a different bucket so the BI-P020 cache genuinely misses), the same 120 again through the same shipped cache now hitting, and 220 exploration queries, that last number chosen so explore.p99's min_samples of 200 is met rather than reported low-confidence. Wall-clock durations, through the shipped producer and the shipped evaluator, so the evidence is written by the code under test.

objective	status	observed	target	n
dash.availability	met	1.0	≥ 0.995	240
dash.p95_first_query	met	9.5 ms	≤ 3 000 ms	120
dash.p95_cached	met	0.026 ms	≤ 400 ms	120
dash.error_rate	met	0	≤ 0.005	240
explore.p95	met	25.0 ms	≤ 10 000 ms	220
explore.p99	met	31.7 ms	≤ 60 000 ms	220
explore.max_result	met	96 rows	≤ 1 000 000	220
dash.freshness	not_measurable_here	—	—	0
explore.timeout	not_measurable_here	—	—	0
report.completion_sla	insufficient_data	—	—	0
report.delivery_sla	not_measurable_here	—	—	0

fully_measured: false, measured_fraction: 0.64. The four that produced no number each say why. A baseline table listing only the rows that worked is how an estate comes to believe it measures more than it does.

The evidence also records what is narrower than production, because these numbers will be quoted: the cached path is the in-process reference cache and not Valkey, every latency is the engine round trip with no HTTP or CL0UD-authorization layer around it, and there is no concurrency.

Adversarial checks. A "cold" sample served from cache fails; a cache "hit" that missed fails; a cached p95 that is not faster than the cold p95 fails; dropping the exploration sample to 60 fails on explore.p99 being low-confidence rather than quietly recording a p99 over 60 requests.

Verification

• pnpm vitest run — 928 passed, 174 skipped, 0 failed.
• CLICKHOUSE_URL=… pnpm vitest run tests/integration/semantic-parity.integration.test.ts — 5 passed, ClickHouse 26.3.10.60.
• CLICKHOUSE_URL=… pnpm vitest run tests/integration/bi-p103-slo-baseline.integration.test.ts — 3 passed, 460 real queries.
• pnpm typecheck clean; eslint clean on changed files; prettier run on changed files only.
• Evidence: evidence/bi-p029/semantic-parity.json, evidence/bi-p103/baseline.json — both written by the suites under test.

CI, verified from the job log rather than from the badge — Gitea run 13119, job integration (id 29535), which starts its own ClickHouse 24.8 service (a different major version from the 26.3 used locally) and hard-fails when a suite skips instead of running:

✓ tests/integration/semantic-parity.integration.test.ts (5 tests) 4339ms
✓ tests/integration/bi-p103-slo-baseline.integration.test.ts (3 tests) 12701ms
  Test Files 13 passed (13)

Merged under the repo's own rule: main requires 0 approvals, the protected patterns (.gitea/workflows/**, .gitignore) are untouched, and all four required contexts are genuinely green. Nothing here changes a public signature — definition_filters is optional on both ResolvedMetric and SemanticMetricRef, and the two altered helpers are module-private.

BI-P029: the cited parity test did not exist, and it caught a real bug ... 468a87c00c

`semantic-provider.ts` cited tests/integration/semantic-parity.integration.test.ts
as the proof of the one BI-P029 DoD surface it claimed was closed, and
`providerReadiness().proven` asserted the comparison had been made against live
ClickHouse. The file did not exist. The citation was the evidence.

Writing it exposed a divergence that had been shipping:
`compileRequestToClickHouse` had no notion of a metric's OWN filters
(BI-P028 `MetricSpec.filters`). `ResolvedMetric` did not carry them and the
compiler never asked, so a metric defined as "invoiced revenue EXCLUDING
internal transfers" executed as "invoiced revenue". On the committed fixture
that is 11 249 instead of 1 250 for one country -- a plausible-looking number,
9x too large, under the correct canonical metric id. The registry, the
governance checks and the MetricFlow manifest all carried the filter; only the
thing that actually ran did not.

  * `ResolvedMetric` gains `definition_filters`, already resolved onto the
    physical dim_names key so the compilers stay dumb.
  * The ClickHouse compiler folds them into THAT metric's conditional
    aggregate, never into the shared WHERE -- two metrics in one request may
    exclude different rows, and a shared predicate would apply one metric's
    meaning to the other. `renderFilter`'s uniquifier becomes a string so
    request filter `0` and metric filter `0_0m` cannot collide in the
    parameter map.
  * `compileRequestToSemantic` carries them through, and
    `MetricFlowProvider.compile` emits them per metric.

The test runs both compile paths against one live ClickHouse: 0pt's `sumIf`
compiler, and a renderer driven only by the provider's structured query that
shares no SQL-generation code and emits `sum(if(...))` with inlined literals.
It asserts the two SQL strings differ, so parity is not vacuous. Backing the
fix out reproduces the pre-fix numbers, and the suite records them itself
rather than quoting a console: evidence/bi-p029/semantic-parity.json.

Three of BI-P029's four DoD surfaces stay OPEN and still say so: MetricFlow
itself is not executed (no Python runtime is provisioned here), Superset is not
implemented, and the AI Analyst path has not been compared.

BI-P103: the cited evidence/bi-p103 did not exist — measure it ... 7441de5429

Same shape as the BI-P029 finding in the previous commit. `bi-slo.ts` said
"evidence/bi-p103 records the first baselines". There was no evidence/bi-p103.

The catalogue and the evaluator were both real and both well covered — against
SYNTHETIC events. A synthetic event carries whatever duration the test author
typed, so that suite proves the arithmetic and nothing about the system: it
cannot tell you whether a dashboard query takes 8 ms or 8 s. BI-P103's DoD is
one sentence, "measured baselines exist", and it was the part not done.

tests/integration/bi-p103-slo-baseline.integration.test.ts runs 460 real
queries against a live ClickHouse over a 400 000-row fact table -- 120 cold
dashboard queries (each a different bucket so the BI-P020 cache genuinely
misses), the same 120 again through the same shipped cache now hitting, and
220 exploration queries, that last number chosen so explore.p99's min_samples
of 200 is MET rather than reported low-confidence. Every duration is
wall-clock around the real call, and the telemetry goes through the shipped
producer and the shipped evaluator, so the evidence is written by the code
under test.

Measured: 7 of 11 objectives produced a number, `fully_measured` false,
measured_fraction 0.64. The four that did not each say why -- dashboard
freshness is a property of the dataset, the exploration timeout is a
configured ceiling, report completion has no producer in 0pt at all, and
report delivery is N0TIFY's receipt. A baseline table listing only the rows
that worked is how an estate comes to believe it measures more than it does.

The evidence also records what is NARROWER than production, because these
numbers will be quoted: the cached path is the in-process reference cache and
not Valkey, every latency is the engine round trip with no HTTP or
authorization layer, and there is no concurrency.

The suite is adversarial about its own inputs: a "cold" sample that came from
the cache fails, a cache "hit" that missed fails, a cached p95 that is not
faster than the cold p95 fails, and dropping the exploration sample to 60
fails on explore.p99 being low-confidence rather than quietly recording a
p99 over 60 requests.
