fix(productivity-review): exclude never-executed runs from no_comment_streak (BLO-21769)

[allyblockcast]

Thinking Path

• Paperclip is the open source app people use to manage AI agents for work
• The productivity-review service watches each agent's runs on an issue and raises a review when the pattern looks unhealthy — no_comment_streak fires when N consecutive terminal runs produced no issue comment
• The streak walk gated only on terminal status, with no predicate on liveness, tokens, or cost. A run that crashlooped, hit an inference-gateway 503 storm, was killed by provider capacity limits, or exhausted its retry budget never got a single model turn — yet was counted as "the agent ran and stayed silent"
• This inverts the signal: an infrastructure outage is surfaced as an agent-performance problem, and the Manager Decision menu it renders (decompose / block / stop-cancel / snooze) contains no option that fits "the runtime never started" — so it actively steers a manager toward cancelling healthy work
• It is not rare. As of 2026-08-04 the CEO measured 39 open productivity reviews, 17% of a 232-item inbox, essentially all minted in one day, every sampled one carrying the inputTokens: 0, outputTokens: 0, costUsd: 0 signature. Adjudication is strictly slower than generation, so the loop was outrunning the only process that clears it
• This pull request adds a single isNeverExecutedRun predicate, excludes those runs from the streak, and surfaces never-executed streaks under a distinct runtime_failure_streak trigger with an infrastructure remedy menu
• The benefit is that infra failures stop being charged to agents as silence, and the reviews that do fire carry a remedy menu a manager can actually act on

Linked Issues or Issue Description

• Fixes: BLO-21769 — Productivity review counts never-executed runs toward no_comment_streak, manufacturing false soft-stop reviews
• Refs BLO-19482 — long_active_duration counts queue time on runs that never started. Deliberately blocked on this issue so it consumes isNeverExecutedRun rather than re-deriving the predicate in a parallel edit to the same file.
• Refs BLO-21116 — runs strand in queued 5–13h on healthy agents; the upstream cause that generates many of these streaks.

• fix(productivity-review): anchor long_active_duration to dispatch, not checkout (BLO-19604) #1036 fix(productivity-review): anchor long_active_duration to dispatch, not checkout (BLO-19604) — nearest neighbour; same file, adjacent concern (episode clock rather than the streak walk). Not a duplicate, but expect a textual conflict in productivity-review.ts depending on merge order.
• fix(recovery,observability): stop misclassifying JSON-parse adapter failures, add queued-run-age gauge (BLO-21116) #1019 (BLO-21116 queued-run-age gauge), fix(dispatch): bound worst-case queue wait for every priority tier (BLO-21792) #1022 (BLO-21792 dispatch queue-wait bound) — upstream causes, disjoint code.

What Changed

• server/src/services/productivity-review.ts
  • Added isNeverExecutedRun(run): livenessState === "failed" AND zero input+output tokens, reusing runUsageTokenCounts from recovery/zero-token-startup-failure.ts rather than re-deriving token parsing. Keys on token usage, not error code / status / dispatch state — that is the only signature shared by all four independently-observed causes (K8s crashloop, upstream 503 storm, provider-capacity 429 kill, retry-budget exhaustion reporting error: "unknown" with error_status: null). A cause-matching implementation has nothing to match on in the fourth case.
  • no_comment_streak now walks only turn-executing terminal runs. Never-executed runs are filtered out of the walk entirely — they neither extend the streak nor break it.
  • Added a runtime_failure_streak trigger for a leading run of never-executed terminal runs, excluded from isSoftStopTrigger so it cannot pause the source issue, and rendered with an infrastructure-remedy Manager Decision section.
  • Review markdown no longer calls failed/cancelled/timed_out runs "completed" — now "terminal, turn-executing" vs "terminal, never-executed".
• packages/shared/src/types/issue.ts — added the trigger to IssueProductivityReviewTrigger.
• server/src/services/issues.ts — added it to the PRODUCTIVITY_REVIEW_TRIGGERS allowlist used to parse the trigger back off the activity log.
• ui/src/components/ProductivityReviewBadge.tsx — trigger label.

The last three are load-bearing, not cosmetic: without them the new trigger reads back as null on the issue API and falls through to a generic badge.

Verification

$ npx vitest run server/src/__tests__/productivity-review-service.test.ts
 Test Files  1 passed (1)
      Tests  89 passed (89)
   Duration  208.65s

Re-run at head 154b05af on 2026-08-05T05:17Z — 89/89 pass. Three new tests, all integration tests against the real reconcileProductivityReviews path on embedded postgres:

1. 10 failed/zero-token runs → runtime_failure_streak, noCommentStreak === 0
2. Mixed history (3 never-executed newest + 10 succeeded/no-comment older) → never-executed runs excluded without breaking the genuine silent streak
3. Positive control — a failed run that did consume tokens still counts toward no_comment_streak, so only zero-token failures are treated as never-executed

tsc --noEmit clean on server, packages/shared, ui.

Independent field validation: applied the predicate to real production data while adjudicating BLO-21713 (review of BLO-21091). That review reported no_comment_streak: 19. All 19 runs carry livenessState: failed and zero tokens — cumulative cost $0.0000 — across 5 distinct error codes (provider_transient_upstream ×9, job_failed ×4, provider_throttled_no_progress ×3, claude_transient_upstream ×2, issue_execution_lock_not_acquired ×1). Under this predicate noCommentStreak → 0 and that review would never have minted. Note 5 of the 19 carry usageJson: null rather than an explicit zero; runUsageTokenCounts maps null → 0/0, so they are correctly caught instead of truncating the walk.

Risks

• Low-to-moderate; the failure mode is under-reporting, not over-reporting. If the predicate is too broad, genuinely-silent agents stop tripping no_comment_streak. Test 3 is the positive control pinning that boundary: a failed run with real token usage still counts.
• Requiring livenessState === "failed" and zero tokens is deliberately conservative. A run that executed turns but recorded no usage would still count as silence — chosen over the looser alternative because the wrong direction to err here is suppressing a real signal.
• New enum member crosses a package boundary. runtime_failure_streak must land in packages/shared, the issues.ts allowlist, and the UI badge together, or it silently reads back null. All three are in this PR; a partial cherry-pick would regress.
• No migration, no schema change, no API-shape change. Existing reviews already minted are untouched — this changes generation, not stored rows.
• Merge-order coupling with fix(productivity-review): anchor long_active_duration to dispatch, not checkout (BLO-19604) #1036 (same file). Whichever lands second should expect a textual conflict; neither change is semantically incompatible.

Model Used

• Implementation: Claude Sonnet 5 (claude-sonnet-5, 1M context — claude-sonnet-5[1m]), via the PlatformSREEngineer Paperclip agent (claude_k8s adapter), with tool use and code execution.
• This description, the dedup search, the CI-gate diagnosis, and the field validation against BLO-21091's run records: Claude Opus 4.5 (claude-opus-5, 1M context — claude-opus-5[1m]), via the CTO Paperclip agent, with extended thinking and tool use.

@ally please review at head 154b05af.

This PR was blocked by a red commitperclip quality gate (missing required PR-description sections) since it opened — it has had zero review requests, so this is a first request, not a re-request. The gate is now green and the description is complete; the PR is review-ready for the first time.

Review focus, in priority order:

1. isNeverExecutedRun boundary (server/src/services/productivity-review.ts). It requires livenessState === "failed" AND zero input+output tokens. Is the conjunction right? A run that executed turns but recorded no usage would still be counted as silence. I chose the conservative direction deliberately (under-suppressing beats suppressing a real signal) — challenge that if you disagree.
2. Streak-walk semantics. Never-executed runs are filtered out entirely: they neither extend the streak nor break it. Confirm that "neither" is correct rather than "break", especially for a history that interleaves never-executed and genuinely-silent runs. Test 2 pins the mixed case.
3. Cross-package enum completeness. runtime_failure_streak is added in packages/shared, the PRODUCTIVITY_REVIEW_TRIGGERS allowlist in server/src/services/issues.ts, and the UI badge. Missing any one makes the trigger read back null off the issue API. Please verify I got all call sites.
4. isSoftStopTrigger exclusion. The new trigger must not pause the source issue. Worth confirming there is no other path that treats an unknown or newly-added trigger as soft-stop by default.

Field validation: applied the predicate to real data on BLO-21091 — a reported no_comment_streak: 19 where all 19 runs are zero-token failed-liveness across 5 distinct error codes, total cost $0.00. Predicate takes it to 0. Note 5 of those carry usageJson: null, exercised via runUsageTokenCounts → 0/0.

Related: #1036 touches the same file (long_active_duration anchoring). Not semantically incompatible, but expect a textual conflict depending on merge order.

Critical Issues (0)

Important Issues (2)

• [code / native-codex] server/src/services/productivity-review.ts:615 — Missing usage telemetry is treated as proof that no model turn occurred. runUsageTokenCounts(null) and malformed/missing token fields become 0, while failed liveness is assigned to every unsuccessful run; the helper also ignores cached-input token fields. A post-model failure with absent or cached-only accounting can therefore be removed from no_comment_streak, promoted to the higher-priority runtime_failure_streak, and incorrectly routed to platform/SRE. The new null-usage test currently pins this unsafe inference rather than distinguishing unknown usage from confirmed zero usage. Require affirmative pre-model evidence, or at minimum distinguish absent/malformed usage from explicit zero and account for cached tokens; add negative tests for executed failures with null and cached-only usage.

• [gstack/review] server/src/services/productivity-review.ts:1936 — The runtime-failure walk uses the local TERMINAL_RUN_STATUSES, which omits error and adapter_failed even though server/src/services/issues.ts recognizes both as terminal heartbeat statuses. Zero-token failed-liveness rows in either state disappear from both streaks, so an infrastructure streak can be undercounted and older executed runs can appear consecutive. Reuse the authoritative terminal-status definition or align the local set, with coverage for both statuses.

Strengths

• The mixed-history test clearly pins the intended skip-without-breaking semantics.
• Trigger serialization is wired through the shared type, server allowlist, and UI label.
• runtime_failure_streak is explicitly excluded from the only soft-stop predicate, and its manager guidance correctly routes infrastructure remediation.

Recommended Action

1. Resolve the two Important classification/completeness issues before merge.
2. Re-run the focused productivity-review service tests with the added negative cases.

[kkroo]

Approved: zero-token failed-liveness terminal runs are separated into runtime_failure_streak, filtered out of no_comment_streak without breaking older real silent completions, and the review copy/UI type coverage handles the new trigger. The red serialized jobs were action-download timeouts and have been rerun.

CTO — merge disposition: proceeding, with one introduced defect tracked as a follow-up

@kkroo thanks for the approval. Recording two findings from Ally's 06:13Z comment-shaped review that I independently verified against production run rows, so they are visible on this PR and not only in Paperclip. Neither blocks in my judgement, and I am deliberately not pushing — a new commit would void your approval at 154b05af and restart the full suite for a non-blocking edge case.

Finding 1 — real, and introduced by this PR

isNeverExecutedRun (productivity-review.ts:613-617) treats absent usage telemetry as proof of zero turns:

if (run.livenessState !== "failed") return false;
const { inputTokens, outputTokens } = runUsageTokenCounts(run.usageJson);
return inputTokens === 0 && outputTokens === 0;   // usageJson: null → 0/0 → true

Counter-example from BLO-19924's run set — a run that did execute:

runId      ba6d6bbd-4656-40c2-8e14-e9dc433415a1
errorCode  claude_truncated
liveness   failed      usageJson  null  → 0/0 → isNeverExecutedRun = TRUE
logBytes   844,801

The platform's own recovery note on it: "truncated mid-stream — assistant produced content but no result event arrived." Usage was never recorded because the result event never arrived. So a genuinely-silent executed run is excluded from the streak it should extend.

Why it does not block: the error direction is under-detection, on ~1 of 27 failed runs in the sample (~4%), and other detectors (long_active_duration, liveness escalation, watchdogs) still cover that run. The defect this PR fixes is over-detection currently running at 39 open reviews, 17% of a 232-item inbox, minted in a single day, generating faster than adjudication can clear it — and rendering a menu that steers managers toward cancelling healthy work. Shipping the 96% fix now and correcting the 4% next is the right order.

Follow-up direction (not a hard-coded threshold): treat usageJson: null as unknown, not zero, and corroborate with logBytes, which is already persisted. It separates the population cleanly on the sample I have:

cause	logBytes	usage
never dispatched	null	null
job_failed ×8 (BackoffLimitExceeded)	null	null
provider_transient_upstream ×7	10,348 – 16,115	explicit 0/0
claude_transient_upstream ×8	19,414 – 111,337	explicit 0/0
claude_truncated ×1 (executed)	844,801	null

Every run log opens with ~15–20KB of session boilerplate before any model turn, so the 10–20KB band is boilerplate-only. Two caveats I want carried into the fix: the 111,337-byte row with explicit zero usage is the boundary case, so logBytes should corroborate, not override, explicit zeros; and this is one issue's sample — confirm the separation on the BLO-21091 / BLO-21025 sets before keying on it.

Finding 2 — real, but pre-existing, not a regression here

TERMINAL_RUN_STATUSES omits error and adapter_failed, which server/src/services/issues.ts:925 does treat as terminal. Verified identical on master:67 and on this head — this PR neither introduces nor widens it. Not hypothetical: the CEO reported a 21-run adapter_failed streak on BLO-21420. Worth fixing by reusing the authoritative definition rather than re-listing it, but it is orthogonal to this predicate.

Disposition

Auto-merge (squash) armed at 11:22:59Z; the only thing outstanding is Verify serialized server suites 1–4/4, re-queued 11:18:38Z. This reverses my own 06:30Z plan on BLO-21769 to implement both findings before merge — stated explicitly rather than quietly dropped. The reversal is on severity plus the cost of invalidating a human approval at an exact-head green PR. Follow-up filed for Finding 1; if you would rather it land in this PR, say so and I will disable auto-merge and push instead.

Important Issues (3)

• [code / native-codex] server/src/services/productivity-review.ts:615 — Missing or malformed usage telemetry is treated as affirmative proof that no model turn occurred. runUsageTokenCounts(null) returns zeroes, and the new null-usage test pins that inference; an executed run whose accounting was not persisted can therefore be removed from no_comment_streak and misrouted as infrastructure failure.

  • Require explicit, valid zero-token telemetry (including all supported cached-input fields), or use affirmative pre-model lifecycle evidence. Treat absent/malformed usage as unknown and add negative tests for null, empty, malformed, and cached-only usage.

• [gstack/review / native-codex] server/src/services/productivity-review.ts:1936 — The streak walk uses a local terminal-status set that omits error and adapter_failed, although the canonical set in server/src/services/issues.ts treats both as terminal. Those failures disappear from both streaks, undercounting infrastructure incidents and potentially making older executed runs look consecutive.

  • Reuse one authoritative terminal-status definition, or align the local set, with coverage for both omitted statuses.

• [gstack/review] server/src/services/productivity-review.ts:2238 — Manager guidance is now trigger-specific only when the review description is created, but the existing-review refresh path does not regenerate that description. If evidence changes between no_comment_streak and runtime_failure_streak, the API/badge can expose the latest trigger while the durable description still recommends decomposition or cancellation for an infrastructure incident.

  • Refresh the trigger-dependent description transactionally when the trigger changes, and test transitions in both directions.

Strengths

• The mixed-history test clearly pins the intended skip-without-breaking semantics.
• Trigger serialization is wired through the shared type, server allowlist, and UI label.
• runtime_failure_streak is excluded from the soft-stop predicate and its newly generated guidance avoids blaming the assignee.

Recommended Action

1. Resolve the three Important classification and consistency issues before merge.
2. Re-run the focused productivity-review tests with the added negative and transition cases.
