The first L4 qualification attempt is incomplete and unqualified. The original runner refused the eighteenth trial because it could not reserve a complete trial plus cleanup. Seventeen Evidence export also failed: the operator advertised a 58,139,975-byte archive, but the terminal and stopped-app logs retained only a partial export with gaps and truncated chunks. The full archive hash could not be verified, so these logs do not establish audited numerical, memory, or performance results. The exact owned app was stopped with zero containers verified at 2026-10-17 00:23:36.897 UTC. The failed attempt and transport receipts are retained; no missing trial or measurements will be filled in. Measured source: |

Qualification failed; this PR remains blocked from merge. The third attempt completed all 18 fresh-process trials, 54 measured phases and 81,507 measured SDK calls on one L4. Independent reconstruction from the complete raw archive reproduced every metric and all 12 fixed gates: N fails 4/6 and R fails 6/6. No failed trial was dropped and no threshold changed. B is unchanged baseline; N is the candidate without LoRA declarations; R selects base after adapter activity with two adapters resident. Ratios are candidate/B for latency and B/candidate for throughput. Every metric requires point≤1.01, one-sided 95% upper≤1.03 and every paired ratio≤1.10.
The untimed observer also has a concrete coverage defect: 1,214 outer scoring batches contain zero actual-forward records. The resulting empty-list checks do not establish actual tuner state, logits, or forward/mutation exclusion. Those claims remain unqualified despite the individual trials reporting success. The source/performance diagnosis and a fail-closed observer correction are ongoing; no further allocation is running. The verified archive contains 82 members, 20,905,270 compressed bytes (SHA-256 Measured source is git checkout --detach 445c5b303a15e852bd094505e0021fe8eb4768e0

@coderabbitai review Please review the frozen head 482b599. The only additions since the reviewed f06f414 are the baseline-only stability diagnostic and its tests. The diagnostic explicitly cannot qualify the candidate. The earlier failed performance run remains recorded, and merge remains held pending successful candidate qualification. |

The complete baseline-only diagnostic failed its fixed stability test: 8/12 directional gates passed, 4/12 failed; The harness was pinned to Every direction must satisfy geometric ratio≤1.01, one-sided 95% upper bound≤1.03 and every paired ratio≤1.10. Throughput ratios are inverted so values above 1 indicate degradation.
Numerical and observation controls passed: 36 replay batches contained 48 actual finite, base-only forward records covering 1,008 rows; all 252 replay requests had correct tokenizer usage. Matched-shape/cross-process/reset comparisons were unchanged, and model/head/tokenizer/tree/tensor state was restored. This is baseline evidence; it does not qualify the revised candidate or establish quality or throughput claims. The archive is 15,332,396 bytes with 142 independently verified members, SHA-256 Whole-call GC/CPU counters include warmup, measurement, drain and evidence processing. Own-cgroup/PSI data was unavailable; zero recorded fault/context-switch counters do not establish absence of pressure. These observations do not identify the cause of variation or show that additional warmup solves it. The earlier full candidate failure and initial incomplete attempt remain preserved. Merge remains held for performance qualification. A separate model-free CPU probe verified a benchmark-owned response-hook cycle and phase-long Response history. Removing the owned hook releases the benchmark Client; ordinary SDK namespace cycles and HTTPX Complete compact diagnostic record{"schema":1,"experiment":"baseline-only stability

@coderabbitai review Please review exact head All 133 combined serving/benchmark CPU tests, Ruff/formatting and type checking pass. Independent controls cover primary-error preservation, malformed protocol, cancellation, child/parent death, callback integrity and clock/source consistency. Local callback calibration retains every sample and estimates mean overhead only. The prior failed hardware result remains unchanged; a fresh complete qualification is pending and the PR remains draft. |

The isolated-client qualification at The SDK child completed C1/C4/C16, exited 0 and was reaped. The worker then rejected the C16 combined GC-observer cost estimate: 0.18354554%, above the prospective 0.1% budget. Its recorded callback self-duration contributes 0.05525818%; the fixed 10-microsecond allowance per callback contributes 0.12828736%. C1 and C4 are below the budget. No N/R trial ran and no complete twelve-comparison result exists. The separate host calibration passed its fixed mean-cost checks. That does not waive the per-phase gate, establish a worst-case callback bound, or justify changing the failed result. The operator and controller exited 1. The complete retained archive has 29 verified members, 7,578,554 compressed bytes, SHA256 The next benchmark change is to remove added per-event GC callbacks from timed qualification, retaining the isolated SDK process, ordinary GC, boundary resource/collection counters, and every original numerical, lifecycle, memory and performance requirement. Individual GC pause durations and callback-cost estimates will be explicitly unavailable in that method, not reported as zero. This is a separate prospective method revision; the instrumented attempt and its failed budget remain unchanged. No new allocation has started. CodeRabbit approved the measured source and all twenty-one reported CI/review checks passed. The PR remains draft while the reduced-instrumentation method is implemented and reviewed, before a complete qualification. |

@coderabbitai review Please review commit The benchmark now checks GC state only at phase boundaries and installs no per-event callbacks in either timed process. Actual pause and observer-cost measurements are explicitly unavailable; the historical failed run remains failed. The serving implementation, request loop, numerical and memory limits, statistical gates, and cleanup bounds are unchanged. Validation: 142 benchmark tests passed with no skips, including real SDK/server lifecycle checks; 19 independent focused checks passed. A negative control against the previous instrumented commit fails at recorder construction as intended. Lint and type checks pass. Fresh GPU qualification is still required before merge. |

Run7 completed the full protocol, but performance qualification failed: 4 of 12 gates passed. The PR remains unqualified. An independent audit verified the full archive, source/environment provenance, all 18 trials and 54 phases, raw request counts, numerical/lifecycle checks, memory checks and cleanup, and recomputed every performance gate. No trial or pair was excluded. This prospective method used one separate SDK interpreter per server trial and kept normal GC enabled. The harness added no per-event GC callback; boundary snapshots cannot measure actual GC pauses. Earlier failed attempts remain failed, including the previous full qualification. This result does not establish the cause of their variation. B is baseline with no declared adapter; N is candidate with no declared adapter; R is candidate with base selected after adapter activity and two adapters retained off-tree. Ratios are candidate/B for latency and B/candidate for throughput, so higher is worse. Each metric must satisfy all three unchanged limits: geometric ratio ≤1.01, one-sided 95% t upper bound ≤1.03, and every paired ratio ≤1.10. The six fresh-process blocks are the statistical units.
All 12 point estimates meet 1.01. Eight upper bounds fail; N/C4 p95 also exceeds the pair limit at zero-based block 5 (1.103578), and R/C1 p95 at block 1 (1.110365). The failed precision and pair criteria are not waived because point estimates look favorable. The run preserved 805,079 measured SDK calls and 1,620 warmups. All 18 correctness/lifecycle trials and memory gates passed. Untimed observation captured 1,730 real model forwards; timed concurrent batch membership remains unknown. Candidate base outputs matched the paired baseline shape oracles exactly for the observed checks. N added zero measured live CUDA bytes; R added the expected 147,456 bytes for two fixture adapters, and final adapter removal restored initial allocation. Reserved allocator memory, full-model teardown retention and RSS are descriptive, not a zero-memory or leak-free claim. The deterministic untrained adapters prove reversible effects and lifecycle behavior, not ranking quality or support for other architectures.

@coderabbitai full review Please review head e906144. The new benchmark entry point prepares three archived server/SDK pairs, grants one complete phase at a time, defers finalization until all nine phase acknowledgements, and joins bounded cleanup through cancellation. Baseline-pilot mode explicitly maps every role to baseline source/configuration and cannot report candidate qualification. Validation: 174 benchmark tests pass, plus 29 independent focused controls and a separate actual coordinator-cancellation proof. Production packages and dependency locks are unchanged. The complete earlier GPU qualification remains failed and is retained above; the new baseline-only pilot has not run. This PR remains draft pending experimental qualification. |

if lora_paths:check alone keeps the manager and all LoRA state off the path without declarations. If you move the import, updatetest_never_lora_has_no_manager_or_optional_imports. That test should then assert only that_loraisNoneand that the capability methods report no support. If the import cost is a measured startup concern, record that exception in AGENTS.md before you keep the deferred import.♻️ Proposed change

The README input-directory mismatch and missing shallow-history guards are confirmed. A focused documentation/test follow-up is in progress; the runtime harness and serving implementation remain frozen for the separately reviewed baseline-only pilot. For the deferred manager import: PEFT is indeed a declared package dependency. The optional boundary here is the runtime-LoRA capability. Keeping the new LoRA module unimported when there are no declarations is an explicit compatibility constraint for this change, alongside preserving the ordinary model and score path. The constructor guard alone would preserve manager state but would not preserve that import boundary. I am retaining the deferred import as a scoped exception for this capability; this is not a measured startup-performance claim. The existing regression control verifies that boundary. |

@coderabbitai review Please review current head The three full-history cases passed, and three simulated shallow-history cases confirmed the expected early skip. Ruff check and formatting pass. This follow-up changes only the README and test history guards; benchmark runtime and production code are unchanged. The PR remains draft, and the earlier failed hardware qualification remains unchanged. |

@coderabbitai review Please review exact head Validation: 324 focused tests passed (one existing flash-attn skip), all 175 committed-archive benchmark controls passed, and 13 independent routing/lifecycle controls passed. Prior failed performance qualification remains failed; this change makes no throughput or zero-overhead claim. The PR description now reflects the final contract. |

Runtime LoRA now requires the explicit
sie_server.adapters.cross_encoder.runtime_lora:CrossEncoderLoraAdapterprofile and declared adapter aliases. The ordinary CrossEncoder module is restored byte for byte to the baseline; its factory routing, constructor, scoring and inherited lifecycle hooks remain unchanged. Existing experimental profiles that suppliedlora_pathsto the ordinary class must migrate to the explicit path.The opt-in class reuses the reviewed manager and native scoring methods. When base is selected, original module and parameter objects remain on the active tree while adapters stay resident off-tree. Existing source authorization, capacity, rollback, poisoning, eviction and final-unload checks remain in force. Manager readiness and runtime admission work remain in the opt-in path.
Validation: 324 focused adapter/loader/metering and benchmark checks passed with one existing flash-attn skip; all 175 benchmark CPU checks passed on immutable source archives, including real tiny-BERT SDK lifecycle and process cleanup. Ruff and type checking passed. Previous actual MiniLM lifecycle evidence maps to the unchanged manager/scoring implementation; the new explicit profile has not been remeasured on the pretrained checkpoint. Earlier failed performance gates remain failed; this change makes no throughput, trained-adapter quality or zero-overhead claim.
Independent review: 13 additional cases passed, including actual loader and HTTP routing, source identity, and native module/storage identity.
