Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
Runs labeled InfraFailure represent infrastructure problems rather than real test signal, so they must not contribute to the daily totals or the cumulative summaries that back Sippy's reports. This change: - Excludes InfraFailure-labeled runs from test_daily_totals and test_cumulative_summaries at write time (pgwriter) and partition-prunes the summary queries by release and date. - Adds pkg/db/infrafailure with RecordInfraFailure and SubtractNewInfraFailure, which materialize the summary-table delta for a run that becomes an infra failure after it was already counted. The subtraction reuses LookupProwJobRunPartitionKeys, is idempotent, and cascades through the carried-forward cumulative rows. - Wires the re-evaluator to perform the coupled subtraction inline inside the same row-locked transaction that replaces the prow_job_runs labels array, preserving the "InfraFailure label in PostgreSQL == subtraction done" invariant. release_job_runs is not coupled to the subtraction. - Adds integration coverage for the subtraction, idempotency, write-time exclusion, flakes, per-test/per-suite/per-release scoping, and the cumulative-summary cascade. Review fixes folded in: - Run the re-evaluator transaction with WithContext(ctx). - Suppress the gosec G115 false positive on the PostgreSQL serial run ID conversion (int64(jobRun.ID)) with a scoped nolint. - Assert the cumulative summaries (PrefixSum* columns) for today and the carried-forward tomorrow row in the idempotency, per-test, per-suite, and per-release integration tests, for both the affected and unaffected dimensions.

The TestOutputs and TestDurations read-time queries exclude runs labeled InfraFailure via a WHERE clause, but no integration test verified those query paths actually filter those runs out. Add TestTestOutputsExcludesInfraFailureRuns and TestTestDurationsExcludesInfraFailureRuns, which seed two runs of the same test on the same day (one InfraFailure-labeled, one clean) along with their test results and failure outputs, then assert each query returns only the clean run's data. Add fixtures to support the read-time query joins: WithLabels (job run labels), WithDuration (test result duration), and CreateProwJobRunTestOutput (the prow_job_run_test_outputs row TestOutputs joins on). The fixtures use timestamps relative to the current date because the queries constrain rows to current_date - interval '14' day. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

After merging main, query.TestDurations returns map[civil.Date]float64 (main changed the return type from map[string]float64). Index the durations map in the read-time InfraFailure exclusion test with a civil.Date key instead of a formatted string, resolving the typecheck failure: test/integration/infrafailure_test.go:568:35: cannot use dateKey (variable of type string) as civil.Date value in map index (typecheck) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
….Now() recentReadQueryDay() computed fixture timestamps from time.Now().UTC(), tying the TestOutputs/TestDurations exclusion tests to the Go process wall clock and making failures hard to reproduce. Query the testcontainer database for current_date and offset from it instead, so fixtures stay anchored to the same clock the production queries' "current_date - interval '14' day" filters use. This is deterministic for a given run and cannot drift outside the 14-day window. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
recentReadQueryDay no longer queries the database for current_date. The read-time TestOutputs/TestDurations queries constrain rows to current_date - interval '14' day, so fixtures only need a timestamp inside that window; anchoring to time.Now() is sufficient. time.Date() still builds a deterministic 10:00:00.000 UTC timestamp with no nanosecond carryover. The helper now takes no parameters, and both callers (TestTestOutputsExcludesInfraFailureRuns, TestTestDurationsExcludesInfraFailureRuns) invoke it with no arguments.

Summary
Excludes InfraFailure-labeled job runs from Sippy's summary tables (
test_daily_totalsandtest_cumulative_summaries). These tables drive 9+ consumers (Component Readiness, test analysis, install/upgrade reports, release health, job-run risk analysis, and the chat agent). Currently, infra-failure noise propagates through all of them.Core principle: When a job run is marked as InfraFailure, its test results are subtracted directly from the existing
successes,failures,flakes, andrunscolumns. No new columns, no consumer query changes needed for summary-table users.Jira: TRT-2884
What This PR Contains
This is PR 1 (Foundation) of a multi-PR effort. It provides the core subtraction mechanism, write-time exclusion, re-evaluator integration (temporary stop-gap), and non-summary query filters.
1.
RecordInfraFailure—pkg/db/infrafailure/infrafailure.goThe primary entry point for recording an infra failure. Atomically sets the InfraFailure label and subtracts the run's test results from summary tables.
RecordInfraFailure(ctx context.Context, dbc *gorm.DB, prowJobRunID int64) errordbc.WithContext(ctx).Transaction(...)subtractFromSummaries(see below)2.
subtractFromSummaries(unexported shared function)Extracted from
RecordInfraFailureso it can be shared by bothRecordInfraFailureandSubtractNewInfraFailure. Runs inside the caller's transaction. Does NOT set the InfraFailure label — the caller handles that.query.LookupProwJobRunPartitionKeys(tx, prowJobRunID)(reuses shared function from PR Trt 2709 partitioning phase2 query partitioning #3907)DROP TABLE IF EXISTS+CREATE TEMP TABLE infra_failure_deltas ON COMMIT DROP AS (...)— materializes deltas once, both subsequent UPDATEs read from ittest_daily_totals(successes, failures, flakes, runs) with partition-pruning WHERE filterstest_cumulative_summaries(prefix_sum_*columns) from affected date onward3.
SubtractNewInfraFailure(exported, temporary stop-gap)For the re-evaluator to call within its own
SELECT FOR UPDATEtransaction. Checks whether InfraFailure is already in PG labels — if so, no-op (subtraction already done). If not, callssubtractFromSummaries. Does NOT set the label — the re-evaluator's full-replace handles that.This function is temporary — it will be removed when the Pub/Sub pipeline is active, replaced by a single path through
RecordInfraFailure.4. Write-time exclusion
Prevents InfraFailure-labeled runs from being counted in summary deltas at write time:
createBatchDeltas(pgwriter.go): JOIN totmp_prow_job_runswith partition key columns (prow_job_release,timestamp) in ON clause + WHERE to exclude InfraFailure-labeled runsdailysummary.go: Same JOIN toprow_job_runs+ WHERE exclusion, with partition key columns in ON clause5. Re-evaluator change (

release_job_runspath is unchanged — it uses the merged set as-is (not part of the summary table invariant).This inline subtraction is a temporary stop-gap — it will be removed when the Pub/Sub pipeline is active, replaced by a single path through
