Summary

Adds nightly predictions and qualified publication to the branch-aware E2E accuracy overview from merged PR #216. Targets main and includes the shared Pages integration from merged PR #215.

  • Daily at 10:17 UTC: evaluate the scheduled main SHA and the head of every discovered release/* branch (up to 255 release branches; larger matrices fail explicitly). Each branch gets its own pinned revision, wheel, campaign, and artifacts. The matrix runs at most two branches at once; a failed branch does not cancel others. Manual dispatch evaluates one explicit branch/SHA.
  • Main reuses a checksum-verified amd64 nightly wheel for the same SHA, including while staging waits, or builds one. Releases build their own exact wheels. Both AISimulate replay and the bundled legacy AIC baseline use the same branch wheel.
  • The campaign reads pinned public InferenceX measurements, runs bounded CPU predictions, and accounts for every selected point. Accuracy is advisory and does not gate releases.
  • Completed matrices trigger Pages. Successful branches can publish even if another branch failed. Pages validates each branch's qualification job in the artifact's exact run attempt, source ancestry, checksums, coverage, and public fields. Rerunning failed jobs preserves successful branches' original attempt provenance. Failed campaigns retain prior evidence.
  • The shared Pages workflow preserves FPE/Nightly qualification and combines their data with accuracy results. All branch results use the trusted main UI, including feat(accuracy): support branch snapshots and CLI comparison drilldown #216's latest branch-name and replay-count validation.

Review map

  • Risk: High — measurement interpretation, artifact trust, and public publication.
  • Entry points: .github/workflows/e2e-accuracy.yml (branch discovery), .github/workflows/e2e-accuracy-branch.yml (per-branch wheel/campaign), scripts/run_e2e_accuracy.py (predictions), and scripts/prepare_e2e_accuracy_pages.py (publication).
  • Public contract: optional snapshot.campaign provenance and a two-file e2e-accuracy-web-<branch-key> artifact. The key is the first 16 hex characters of SHA-256 of the branch name. Legacy unsuffixed artifacts remain readable under the successful-whole-run rule.
  • Historical release revisions must support the public adapter/replay APIs and manylinux builder. Missing/duplicate outcomes, failed worker processes, invalid provenance, or no successful matched predictions prevent publication. Revert workflow and consumer integration together to restore committed-only publication.

Validation

  • 395 Python tests passed: campaign, measurement extraction, artifact/publication, overview, Pages, CI contracts, and qualification.
  • 47 JavaScript tests passed: browser state/provenance and executable workflow/Pages gates.
  • Actionlint, Ruff lint/format, legal/ownership/documentation checks, whitespace checks, and a Pages build passed.
  • All inline and outside-diff review findings are addressed, including dataset schema/part validation, timezone-aware completion comparisons, qualified-artifact errors/symlinks, browser policy/exclusion keys, invalid GPU-count boundaries and isolation of unusable prior committed timestamps, documented catalog/permissions/branch limits, and least-privilege workflow coverage.
  • Repaired inherited fix(dsv4): correct GEMM graph timing and MoE workspace accounting #219 CI failures with 49 additional B200/vLLM 0.25.0 registry slices and corrected donor/topology/GEMM test expectations. All existing registry entries and data payloads are unchanged. The 1,922-slice registry check, direct GEMM enumeration regression, and 18 source-isolated workspace tests pass. Native installed-runtime validation awaits Full CI.

Earlier input and native evidence

The following evidence was collected before this stack refresh and its freshness correction. It does not establish the corrected full-cohort count or a prediction run on this head.

  • Downloaded and checksum-verified all 13 public dump parts (~25 GB), then streamed extraction with the pinned PostgreSQL 18 container: 84,289 measurements, 2,449 configurations, and 1,136 runs. The full-input check exposed quoted SQL identifiers; the decoder fix restores exactly the independent extraction's 4,065-point cohort (SHA-256 4dda839cd2f22098b379654f94d1e4b0ca79a23335e77076927ac2e5391daf50). Regression tests include the real quoted precision header.
  • Full-cohort adapter preflight: 1,423 adapted, 2,495 explicitly unsupported, and 147 requiring recipe resolution, with no adapter exceptions. This is an input-coverage check, not a full prediction run.
  • Linux bundled-AIC/native replay smoke: seven eligible points, six successful replays and one explicitly retained SGLang replay failure; the sanitized artifact passed publication validation. This uses the existing wheel at e46be717175acf06bdbbdeadb7aaf9bb2afdae8d, not a PR-built runtime wheel. Full 4,065-point prediction execution and the hosted scheduled workflow remain unverified.

Modeling and data provenance

  • Pins InferenceX db-dump/2026-09-14, including 13 checksums and sizes. Dataset refreshes require a reviewed manifest change. Raw dump SQL is never executed; pg_restore streams three selected COPY tables.
  • Policy latest-complete-config-run-v1: completed successful source runs, one latest curve per configuration/workload/recipe, single-node/single-turn/no offload, positive mean TTFT/TPOT, consistent image, and a 30-day age window within each model/GPU/framework/precision/serving/speculation/workload family.
  • Baseline and replay use one wheel and the baseline's resolved performance-database version. Replay pins max_num_seqs=max(256, concurrency), max_num_batched_tokens=8192, enable_prefix_caching=False, and aic_forward_model="op_level", with seed 0, 80–100% nominal lengths, and ten requests per concurrency slot. Only eligible measurements determine family freshness. Unresolved recipes/adapter inputs and failed baselines are explicitly counted before forming comparisons; replay failures remain gaps.
  • This public API policy differs from feat(accuracy): support branch snapshots and CLI comparison drilldown #216's earlier private campaign recipe mapping. Different cohorts/database versions prevent treating aggregate changes as proof of improved runtime accuracy. Raw latencies, internal IDs, and child logs are not uploaded.

Review and CI status

  • Codex reviewed head: cde686b3a3a051ad708ad620ddf4b347967a5cb2; includes main through cbaf51b6. Fresh review found no remaining actionable issue; all 17 existing review conversations are fixed and resolved.
  • Current-head Fast CI, Pages, and CodeRabbit are refreshing. Full CI follows the current-head initial reviews. Human approval and effective branch rules will be rechecked before merge.
  • This PR delivers campaign execution/publication infrastructure. A new full-cohort accuracy result, hosted branch matrix, and live accuracy deployment remain deferred. Contract tests and mocked fixtures are not predictive-accuracy evidence.

🔀 Multi-repo context ai-dynamo/dynamo, ai-dynamo/aiconfigurator

Linked repositories findings

ai-dynamo/dynamo

  • Dynamo pins aisimulate==0.12.0.dev2; campaign wheel/runtime provenance should preserve this exact version. [::ai-dynamo/dynamo::]
  • Dynamo ReplaySpec ABI is version 1, supporting vLLM/SGLang aggregate or disaggregated topologies and TRT-LLM aggregate; disaggregated attention-DP is unsupported. [::ai-dynamo/dynamo::]

ai-dynamo/aiconfigurator

  • The migration reference requires stable aisimulate==0.12.0 and explicitly excludes development releases, differing from Dynamo’s 0.12.0.dev2 pin. This version distinction should remain explicit in campaign provenance. [::ai-dynamo/aiconfigurator::]
  • InferenceX-derived rows require positive worker counts; MTP rows require explicit nextn and nextn_accepted values. [::ai-dynamo/aiconfigurator::]

📝 Summary

Risk level: High.

Human attention should focus on:

  1. Workflow trust boundaries and artifact validation.
  2. Full-cohort replay coverage and bounded execution.
  3. Pages publication and preservation of prior evidence.

Changed behavior and contracts

  • Adds scheduled and manual E2E accuracy campaigns for main and release/*.
  • Evaluates exact revisions with checksum-verified wheels and a pinned multipart dataset.
  • Runs bounded baseline and replay predictions across the complete cohort.
  • Publishes advisory, branch-specific artifacts.
  • Validates provenance, checksums, coverage, qualification attempts, ancestry, timestamps, exclusion counts, and public fields.
  • Preserves prior evidence when campaigns fail or produce incomplete evidence.
  • Extends build_site with optional accuracy_artifacts.
  • Adds campaign provenance validation and UI rendering.
  • Adds 49 B200/vLLM 0.25.0 registry entries and updates related expectations.

Evidence supplied

  • Current revision is cde686b3a3a051ad708ad620ddf4b347967a5cb2.
  • The working tree is clean.
  • Reported validation includes 395 Python tests, 47 JavaScript tests, workflow and static checks, registry validation, source-isolated workspace tests, and a passing Pages build.
  • Regression tests cover manifest validation, artifact provenance, qualification attempts, ancestry, publication selection, exclusion counts, workflow matrices, branch isolation, and UI validation.
  • CodeRabbit reported no actionable findings. This is not approval.
  • The author reported that review conversations were resolved and that Fast CI, Pages, CODEOWNERS, DCO, and approval checks passed.

Evidence still missing

  • Full-cohort execution, hosted scheduling, live accuracy deployment, and native installed-runtime validation remain unverified.
  • Full CI completion is not confirmed in the supplied evidence.
  • Review finding severity counts are unavailable.
  • Merge readiness cannot be established from the supplied evidence.

Walkthrough

Adds an E2E accuracy system. It validates pinned measurements, runs scheduled or manual campaigns, publishes qualified artifacts through Pages, renders campaign provenance, and adds workflow, parser, campaign, publication, UI, backend-fact, and test coverage.

Explanation

The changed dataset contract uses db-dump/2026-09-14 in .github/e2e-accuracy-dataset.json, and run_e2e_accuracy.py derives the required source URL from that manifest value. The overview builder rejects any different URL. However, the changed accuracy README still documents --source-url .../db-dump/2026-08-24, so following the documented command produces a builder failure. No test checks agreement between the documented command and the manifest.

Resolution

Update the README example to use db-dump/2026-09-14, or document a command that derives the URL from the manifest. Add a documentation contract test that compares the documented release tag with .github/e2e-accuracy-dataset.json and exercises the documented command contract.

Codex self-review of 32d177a, stacked on the current #216 head. Rechecked daily/manual source resolution, exact-wheel reuse and installation, measurement selection and quoted COPY decoding, bounded predictor execution, qualified artifact validation, branch publication, and UI compatibility. All four previously posted findings are fixed and resolved; no remaining actionable finding from this review. Validation: 210 scoped Python tests, 19 JavaScript tests, actionlint, CI-pinned Ruff and policy checks, complete checksum/streamed dataset extraction, matching 4,065-point selection, and native smoke with explicit replay gaps on the existing reference wheel. Current-head Fast CI and Pages passed. Full prediction execution/hosted scheduling are not yet verified. Full CI awaits NVIDIA runner admission, CodeRabbit review is rate-limited, and human/CODEOWNER approval remains outstanding. This comment is self-review evidence, not approval or merge authorization.

datetime.fromisoformat() before comparing them, preserving the existing
missing-value guard for previous.get("aisimulate_completed_at").

In `@scripts/run_e2e_accuracy.py`:
- Around line 75-84: Update the freshness calculation around latest_by_family so
it uses the same eligibility predicate as the selection loop, including
offload_mode, is_multinode, and the per-node GPU limit checks. Reuse a shared
predicate or eligibility helper to keep both paths consistent, while retaining
the selection loop’s per-reason exclusion counters.

In `@tests/test_e2e_accuracy_ui.mjs`:
- Line 92: Extend the rejection-case loop in the test around validateSummary to
include campaigns missing evaluated_revision and campaigns whose published count
differs from data.totals.rows. Ensure both cases assert rejection alongside the
existing invalid run_id, selected, commit_sha, and advisory cases.

In `@tests/test_e2e_accuracy_workflow.mjs`:
- Line 10: Update the embedded-script extraction regex in the workflow test to
accept blank lines within the YAML script block, and add an assertion that the
extracted source contains its final statement so truncation is detected.

🔀 Multi-repo context ai-dynamo/dynamo, ai-dynamo/aiconfigurator

Linked repositories findings

ai-dynamo/dynamo

  • The runtime pins aisimulate==0.12.0.dev2 and registers dynamo.replay.simulation:DynamoReplayRunnerFactory as the AISimulate runner entry point. The workflow’s wheel installation and provenance checks should preserve this exact dependency/entry-point contract. [::ai-dynamo/dynamo::]
  • DynamoReplayRunnerFactory supports only vLLM/SGLang aggregated or disaggregated topologies and TRT-LLM aggregated topology; it advertises replay-spec API version 1 and explicitly does not support disaggregated attention-DP. Accuracy point selection must avoid unsupported rows. components/src/dynamo/replay/simulation.py:35-64 [::ai-dynamo/dynamo::]
  • The runner translates ReplaySpec into run_trace_replay/synthetic replay and requires engine arguments, while replay reports must contain the requested goodput metric. components/src/dynamo/replay/simulation.py:80-123 [::ai-dynamo/dynamo::]
  • Dynamo’s own dependency test requires one exact PyPI AISimulate version and validates consistency across pyproject.toml, the requirements file, and lockfiles. tests/dependencies/test_aisimulate_consistency.py:1-90 [::ai-dynamo/dynamo::]

ai-dynamo/aiconfigurator

  • The compatibility documentation defines the InferenceX contract as one configs.json record plus one matching benchmark row, with PP defaulting to 1 and disaggregated prefill batch defaulting to 1. These defaults must be reflected when converting extracted measurement rows. docs/config_adapter.md:178-189 [::ai-dynamo/aiconfigurator::]
  • Speculative decoding is not inferred: when nextn > 0, nextn_accepted is required and must be within [0, nextn]. docs/config_adapter.md:34-42,217-223 [::ai-dynamo/aiconfigurator::`
  • The documented AIC accuracy pipeline uses cli_estimate, records the backend version actually used, and treats accuracy as report-only rather than release-gating. tools/accuracy_tracking/run_silicon.py:1-18,50-80 [::ai-dynamo/aiconfigurator::]
  • The migration guide explicitly says aisimulate development releases are not the stable transition baseline, while Dynamo currently consumes 0.12.0.dev2; campaign provenance should distinguish this development dependency from a stable release. docs/aisimulate_migration.md:13-19 [::ai-dynamo/aiconfigurator::]

The workflow runs the campaign in the pinned postgres:18-bookworm container, so pg_restore is not an older client. The claimed version-related failure is not reachable in this workflow.

The claim is refuted. actions/checkout@3d3c42e5... is v7, whose fetch-depth: 0 contract fetches all branches and tags. Therefore, refs/remotes/origin/${EVALUATED_BRANCH} exists for the validated main or release/* branch, and the ancestry check does not need an additional fetch.

83-84: 🩺 Stability & Availability

The dependency concern is not established. scripts/run_e2e_accuracy.py imports only standard-library modules and repository-local helpers at module scope. Its aisimulate and aiconfigurator imports are inside functions. The test patches wheel_identity before calling campaign(), so the campaign does not require the installed wheel for those checks. The remaining dependency question requires the local helper imports and test setup to be inspected.

Please review head 45106ed8a5827834e4a10f774ae190dd4dddea77. It adds nightly fresh campaigns for main and every release branch, independent branch artifacts/publication, exact-attempt retry qualification, and incorporates #216 through 8ed9080a218bee23df0d12afcb0d53238ed23121. Both exclusion-count findings from your previous review are fixed and covered by regression cases. Local validation: 327 Python tests, 33 JavaScript tests, and static/policy checks passed.

@jasonqinzhou No actionable findings identified for head 45106ed8a5827834e4a10f774ae190dd4dddea77.

I checked the scheduled release matrix, branch-specific artifact binding, retry-attempt qualification, publication ancestry checks, and exclusion-count validation. The updated validation rejects non-integer and negative count values at the publication boundary.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Reject naive committed timestamps before comparing them.

_accuracy_summary only requires aisimulate_completed_at to be a string. If a committed summary contains a date-only or offsetless ISO value, datetime.fromisoformat returns a naive datetime. Comparing it with the UTC-aware current["completed_at"] raises TypeError and aborts prepare(). Treat naive or unparsable prior timestamps as invalid and raise a clear ValueError.

ai-dynamo/aiconfigurator

  • docs/config_adapter.md:178-189 requires each InferenceX point to combine one configs.json record with its matching benchmark row; PP and disaggregated-prefill defaults are recorded assumptions, and MTP rows require explicit nextn and nextn_accepted. Measurement extraction and request adaptation should preserve these rules. [::ai-dynamo/aiconfigurator::]
  • docs/aisimulate_migration.md:9-19 identifies stable aisimulate==0.12.0 as the migration baseline and says development releases do not satisfy that publication gate. The campaign’s use of Dynamo’s 0.12.0.dev2 pin should remain explicit in provenance rather than being presented as the stable migration release. [::ai-dynamo/aiconfigurator::]

🟡 Minor · Reject dangling qualified-artifact symlinks.

scripts/build_pages_site.py:349
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject dangling qualified-artifact symlinks.

Path.exists() is false for a dangling symlink. This skips the rejection at Line 350 and falls back to repository or ref evidence instead of rejecting the invalid qualified artifact. Check is_symlink() even when the target is missing.

Proposed fix
-        if qualified is not None and qualified.exists():
+        if qualified is not None and (qualified.exists() or qualified.is_symlink()):

As per path instructions: “Corrupt, ambiguous, or unsupported input should fail loudly.”

🟡 Minor · Validate the campaign policy at the browser boundary.

python/aisimulate/docs/e2e-accuracy/app.js:571-572
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Validate the campaign policy at the browser boundary.

The campaign producer and Pages validator require "latest-complete-config-run-v1", so the normal publication path rejects invalid values. However, validateSummary accepts a campaign with a missing or incorrect selection_policy; renderSnapshot then displays that value as policy provenance. Reject invalid policies at this boundary and add negative tests.

Proposed fix
     !Number.isInteger(campaign.published) || campaign.published !== data.totals.rows ||
     !Array.isArray(campaign.backend_versions) ||
     !campaign.backend_versions.every((version) => typeof version === "string") ||
+    campaign.selection_policy !== "latest-complete-config-run-v1" ||

ai-dynamo/aiconfigurator

  • The migration guide explicitly treats stable aisimulate==0.12.0 as the compatibility baseline and says development releases do not satisfy that gate. Since Dynamo currently pins 0.12.0.dev2, campaign provenance should distinguish this development runtime from the stable migration release. docs/aisimulate_migration.md:8-19 [::ai-dynamo/aiconfigurator::]
  • InferenceXSource requires each point to combine one configs.json record with its matching benchmark row; it applies PP/disaggregated-prefill defaults and requires explicit nextn/nextn_accepted for MTP rows. Measurement extraction and request adaptation must preserve these assumptions. docs/config_adapter.md:178-189 [::ai-dynamo/aiconfigurator::]

Validated the remaining CodeRabbit findings on 5b53b12cebe1320a12819b2c0a2c161793fbfd2b, including the findings in review summaries outside inline threads. In addition to the three open conversations, the current code accepts unsupported dataset manifest versions, allows a dangling qualified-artifact symlink to fall back to committed data, accepts missing/unknown browser campaign policies, and compares naive committed timestamps against timezone-aware campaign timestamps. These will be corrected with boundary regressions before resolving the conversations.

The PR adds campaign execution and publication infrastructure. A new full-cohort accuracy result remains explicitly deferred; fixture/contract tests are not evidence of improved model accuracy.

Codex reviewed current head 9c91a4fbde53b1317c55e46fdbe5121eea9704e8, including current main through cbaf51b6, the full campaign/publication diff, and all inline and outside-diff CodeRabbit feedback. No remaining actionable finding from this pass.

The three open conversations are fixed and resolved. The review-summary findings are also fixed: unsupported/malformed dataset manifests fail before downloads or runtime loading; dangling qualified-artifact symlinks are rejected; browser campaign policy must match the supported policy; completion timestamps must parse with an explicit timezone. Tests cover these boundaries and a mocked checksum-pinned extraction through the real COPY parser.

Validation on this head: 380 Python tests and 47 JavaScript tests passed; actionlint, Ruff lint/format, legal/ownership/documentation checks, whitespace checks, and the Pages build passed. The existing human approval remains visible; current-head CI and bot review are being refreshed before merge.

This PR delivers execution/publication infrastructure. A new full-cohort accuracy result and live hosted campaign remain deferred; local fixtures are not predictive-accuracy evidence.

Please finish the current-head review for 9c91a4fbde53b1317c55e46fdbe5121eea9704e8. All three open conversations and the four review-summary findings are fixed, with 380 Python tests and 47 JavaScript tests passing. Both direct and manual Fast CI and Pages are successful. The current status has remained pending since 17:52 UTC; the earlier review command was at the end of the self-review comment.

Merge-gate update for head 9c91a4fbde53b1317c55e46fdbe5121eea9704e8:

  • All 12 review conversations are resolved; GitHub reports APPROVED. Arsene12358 is an active member of both the maintainer and infrastructure CODEOWNER teams, and effective rules retain the existing approval after these pushes.
  • Direct Fast CI, manual Fast CI (35130973845), Pages, CODEOWNERS, and DCO passed. CodeRabbit is still reviewing this head; Full CI has not been dispatched because REVIEW.md requires the current-head initial reviews to finish first.
  • The incorporated main revision cbaf51b64fa460e5ec6146bde407a4c64958212d independently failed Full CI 35130043126: 49 op-backend registry differences; the B200 GDN donor latency pin; DeepSeek-V4 Pro FP8 topology/memory admission expectations; and the common GEMM-case count. These paths are unchanged by this PR. Repairing them would expand this PR into collector/data maintenance, so that scope decision remains with the requester.

The PR has not been merged. Passing Fast CI and accepted approval do not substitute for the Full CI requirement.

🔀 Multi-repo context ai-dynamo/dynamo, ai-dynamo/aiconfigurator

Linked repositories findings

ai-dynamo/dynamo

  • Dynamo requires aisimulate==0.12.0.dev2 on Python 3.11–3.13 and registers the dynamo replay runner through AISimulate entry points. Accuracy wheel validation/reuse must preserve this package and registration contract. pyproject.toml:11-17,116-126 [::ai-dynamo/dynamo::]
  • The replay runner advertises ReplaySpec API version 1 and supports only vLLM/SGLang aggregate or disaggregated topologies and TRT-LLM aggregate topology; disaggregated attention-DP is explicitly unsupported. Campaign point selection must avoid unsupported combinations. components/src/dynamo/replay/simulation.py:39-68 [::ai-dynamo/dynamo::]
  • Dynamo’s consistency tests require the Python package, container wheel, Rust aisimulate-core, and lockfiles to use one exact matching release. tests/dependencies/test_aisimulate_consistency.py:65-125 [::ai-dynamo/dynamo::]

ai-dynamo/aiconfigurator

  • InferenceXSource consumes one configuration record together with its matching benchmark record; its adapter validates hardware, framework, model/precision, positive workload dimensions, worker counts, TP/EP, and disaggregated topology fields. src/aiconfigurator/sdk/config_adapter/inferencex.py:97-231 [::ai-dynamo/aiconfigurator::]
  • Active speculative decoding requires explicit nextn and nextn_accepted, with nextn_accepted finite and within [0, nextn]; no acceptance assumption is inferred. src/aiconfigurator/sdk/speculative.py:25-51 [::ai-dynamo/aiconfigurator::`
  • The migration guide identifies stable aisimulate==0.12.0 as the compatibility baseline and explicitly says development releases do not satisfy that publication gate. This differs from Dynamo’s currently pinned 0.12.0.dev2 and should be represented accurately in campaign/runtime provenance. docs/aisimulate_migration.md:8-19 [::ai-dynamo/aiconfigurator::]

@jasonqinzhou No actionable findings identified for head 9c91a4fbde53b1317c55e46fdbe5121eea9704e8.

I verified the manifest-version gate, qualified-artifact symlink rejection, campaign-policy validation, timezone-aware completion-time comparison, branch-specific qualification, and artifact publication binding. I did not execute repository tests in this environment.

The renewed merge request includes closing the remaining CI blockers. I verified the inherited failures from main cbaf51b6 against the committed source/data before changing their expectations:

These are registry/test corrections for already-merged behavior. They do not change measurements, runtime formulas, collector dispatch, or CI requirements. Full CI will validate the resulting head before merge.

@coderabbitai review

Please review current head af9bdd0032008d57dd8cd3e2fee753862c87b387. The four new conversations are fixed in dc62fa63 and resolved. Commit af9bdd00 also repairs the inherited #219 CI blockers: exactly 49 added B200/vLLM 0.25.0 registry slices with all existing entries unchanged; the GDN donor pin matches the exact published 0.25.0 Parquet row; the topology expectation follows the already-merged residual-width workspace fix; and both GEMM grid counts match direct enumeration. No runtime formulas, data payloads, backend mappings, or CI requirements changed.

Codex self-review of this exact head found no remaining actionable issue. Local validation: 387 accuracy/Pages/CI Python tests, 47 JavaScript tests, GEMM enumeration regression, and 18 source-isolated workspace tests passed. The complete backend-facts check passes with 1,922 slices. Native installed-runtime tests await Full CI (the local extension is unavailable); one local optional native test was skipped. The pre-existing untraced FlashInfer label remains explicitly unverified, without guessed mapping.

Fast CI and Pages are refreshing; Full CI will follow current-head review. A new full-cohort campaign result remains deferred as described in the PR.

@jasonqinzhou No actionable findings identified in the current-tree review of af9bdd0032008d57dd8cd3e2fee753862c87b387.

The registry contains 49 unique B200/vLLM 0.25.0 records. The inspected tests pin the stated GDN donor value, DeepSeek-V4 topology admission, and GEMM counts.

The accuracy manifest, artifact, policy, timestamp, and exclusion-count validation boundaries remain present.

Diff-level verification is inconclusive in this sandbox. The cloned HEAD has no parent, so Git cannot produce the head delta. I did not run repository tests.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Do not let an invalid committed snapshot timestamp abort Pages preparation. When a qualified artifact has the same commit as an existing committed snapshot, completion_time(previous["aisimulate_completed_at"]) can raise for a malformed or timezone-naive value and abort preparation for every branch. Treat the prior timestamp as unusable and skip the replacement so the committed snapshot remains available through the documented fallback.

@coderabbitai review

Please review current head cde686b3a3a051ad708ad620ddf4b347967a5cb2. Both findings from review 5228043187 are addressed in this commit:

  • The GPU-count regression now covers null, boolean, fractional, and negative values for decode and applicable prefill. Each case checks the exclusion reason and preserves the older eligible curve; the inline thread is resolved after push.
  • An invalid or timezone-naive prior committed completion timestamp now preserves that branch's committed snapshot and continues preparing other branches. New matrix tests prove another branch still publishes. Validation of incoming qualified-artifact timestamps remains strict.

Codex reviewed the updated head and found no remaining actionable issue. All 395 scoped Python tests pass; targeted Ruff lint/format and whitespace checks pass. Earlier JavaScript coverage remains unchanged (47 passing tests). Fast CI is refreshing for this exact head, and Full CI will be rerun after current-head review. The preceding Full CI has no failures so far, including the inherited collector/data repairs, but will not be used as final-head evidence.

@jasonqinzhou No actionable findings identified for cde686b3a3a051ad708ad620ddf4b347967a5cb2.

The committed-snapshot timestamp recovery is branch-local. It retains the affected branch and continues publication for other branches. Incoming qualified-artifact timestamps remain strict.

The GPU-count validation excludes null, boolean, fractional, and negative decode or applicable prefill counts before curve selection. The regression cases verify the exclusion reason and preservation of the older eligible curve.

I did not execute repository tests in this environment.
