Objective

Keep conversionSuccessRate semantically stable across live computation, durable ledger replay, restart, and buyer-visible export after changing the denominator from all jobs to terminal outcomes only.

Exact current-head evidence

  • protected base: eb0a32e87e7470469c8fa0f8c67d9583654bef57;
  • exact current head: 734f7d1b8c1349bd46acdc65fe61886222c8136a;
  • the current head includes the reviewed ledger-version migration, boundary coverage, and fail-closed rejection of non-finite or domain-invalid durable KPI numerics;
  • changed paths: KPI response/record/ledger behavior and focused replay/export regressions only;
  • CI 31882698356, Security Scan 31882698357, SAST Semgrep 31882698363, and fuzz 31882698401: terminal-success;
  • mergeable: true;
  • the only inline finding is resolved.

KPI contract

The live conversion success rate is:

succeeded_jobs / (succeeded_jobs + failed_jobs)

and is 0.0 when there are no terminal outcomes. New durable records carry the explicit terminal-outcomes-v1 metric marker. Legacy 12-field records are validated using their historical total-job denominator, then migrated in memory by recalculating the terminal-outcome rate from persisted succeeded and failed counts. Unknown metric versions, malformed current records, non-finite persisted numerics, domain-invalid rates or latency, and persisted rates inconsistent with their declared version fail closed.

Restart replay and AnalyticsController export expose the migrated current meaning rather than the historical denominator. Focused regressions cover legacy replay/export, zero-terminal legacy snapshots, current-format replay, malformed records, numeric-domain failures, and rate/version mismatches.

Scope boundary

This changes KPI denominator/version semantics and durable numeric integrity only. It does not alter tenant query isolation, job lifecycle transitions, telemetry export, persistence technology, or other analytics fields.

Merge gate

Keep this exact head unchanged. Auto-merge may act only after every live required check remains terminal-success, zero valid unresolved findings remain, and a qualifying independent non-author approval is attached to this exact head. Any head movement requires complete exact-head revalidation; predecessor evidence does not transfer.

Merge Risk: 🟠 High · up to b42b5

This change can cause previously stored KPI records to report an incorrect conversion success rate after restart or export. The PR is not merge-ready until existing records are migrated or versioned and the persisted-data behavior is covered.

I found one issue.

  • KPI ledger replay can accept an invalid terminal success rate. In src/main/java/com/clearfolio/viewer/analytics/KpiSnapshotLedger.java, Line 217 adds succeededJobs + failedJobs as int. Both values come from the persisted ledger. A versioned record with large values can overflow this sum. The stored negative or out-of-range rate can then pass requireRate and be returned by /api/v1/analytics/kpi-snapshot-exports. Use long for the denominator. Validate persisted counters as non-negative and internally consistent before calculating the rate. Add a replay test for overflow-sized counters.

Normal job-status handling is correct. The code uses SUCCEEDED and FAILED as terminal outcomes. The legacy replay path and current versioned format are otherwise consistent with the requested KPI semantic change.

GitHub currently reports strix as IN_PROGRESS and coverage-evidence as QUEUED. These checks are not terminal-success.

Freshly rechecked: CI, Security Scan, SAST Semgrep, and fuzz are terminal-success; mergeable is true; the ledger-migration finding is resolved. Review the current seven-file denominator/version and durable-numeric-integrity delta only. Earlier head e7cb543b936f0284e7c8b09142e8817896b0bfbd is historical and its evidence does not transfer.

I found one issue.

  • Persisted KPI counters remain unvalidated and can overflow. In src/main/java/com/clearfolio/viewer/analytics/KpiSnapshotLedger.java, Line 218 calculates the terminal denominator with int. The replay paths accept every parseable int counter. They do not require non-negative values or verify that succeededJobs + failedJobs and the other state counters are consistent with totalJobs. A crafted durable record can therefore replay invalid KPI evidence when its stored rate matches the unchecked calculation. Use long for the terminal denominator. Reject negative and internally inconsistent counters before calculating or accepting the rate. Add replay tests for negative counters, inconsistent totals, and overflow-sized terminal counters.

The KPI denominator update and legacy-record migration are otherwise consistent. The current versioned ledger format rejects unknown versions and rejects non-finite or out-of-range stored rates.

GitHub does not yet show all checks as terminal-success. coverage-source-tree is QUEUED, strix is IN_PROGRESS, and PR #437 is BLOCKED with REVIEW_REQUIRED.

I found one issue.

  • Persisted KPI counters can still produce invalid replayed evidence. In src/main/java/com/clearfolio/viewer/analytics/KpiSnapshotLedger.java, Line 218 adds succeededJobs and failedJobs as int. Both replay paths accept any parseable int counter. They do not reject negative values or verify that the state counters are consistent with totalJobs. A durable record with overflow-sized terminal counters, or with negative counters, can pass requireRate when the stored value matches the invalid calculation. The export endpoint can then return invalid KPI evidence. Use a long terminal denominator. Validate each counter as non-negative. Validate that the state-count total equals totalJobs and that deadLetteredJobs is within its valid subset. Add replay tests for negative counters, inconsistent totals, and overflow-sized terminal counters.

The terminal-outcome denominator, metric-version format, legacy migration, and finite rate and latency validation are otherwise consistent.

GitHub currently reports strix as FAILURE and coverage-source-tree as QUEUED. The PR is BLOCKED and requires review.
