From 01dee023e194ce2a9dc8e5ce1596aed67215e346 Mon Sep 17 00:00:00 2001 From: Hillary Mutisya <150286414+hillary-mutisya@users.noreply.github.com> Date: Fri, 23 Oct 2026 23:13:03 -0700 Subject: [PATCH 01/10] Add BEAM memory benchmark harness Add a TypeScript CLI and durable memory-service bridge for pinned datasets, isolated imports, scoring, resumable runs, and explicit question-failure reporting. Enforce lossless document chunking within extraction and embedding token budgets, reject oversized embedding inputs and content-filtered responses, and skip empty semantic terms. Include offline regression coverage and runbooks. --- ts/packages/aiclient/package.json | 1 + ts/packages/aiclient/src/embeddingInput.ts | 27 + ts/packages/aiclient/src/index.ts | 1 + ts/packages/aiclient/src/openai.ts | 5 + .../chatCompletionsWireApiProvider.ts | 3 + .../aiclient/test/embeddingInput.spec.ts | 83 ++ .../aiclient/test/providerAdapter.spec.ts | 36 + ts/packages/benchmarks/README.md | 6 + ts/packages/benchmarks/package.json | 5 +- .../benchmarks/src/memoryBench/README.md | 180 ++++ ts/packages/benchmarks/src/memoryBench/cli.ts | 93 +++ .../benchmarks/src/memoryBench/data.ts | 226 ++++++ .../benchmarks/src/memoryBench/literal.ts | 116 +++ .../benchmarks/src/memoryBench/normalize.ts | 169 ++++ .../benchmarks/src/memoryBench/protocol.ts | 82 ++ .../benchmarks/src/memoryBench/provider.ts | 266 ++++++ .../benchmarks/src/memoryBench/runner.ts | 719 ++++++++++++++++ .../benchmarks/src/memoryBench/scoring.ts | 226 ++++++ .../benchmarks/src/memoryBench/storage.ts | 96 +++ .../benchmarks/src/memoryBench/types.ts | 72 ++ .../benchmarks/test/memoryBench.spec.ts | 768 ++++++++++++++++++ .../benchmarks/test/memoryBenchFixtures.ts | 120 +++ ts/packages/knowPro/src/conversationIndex.ts | 6 + ts/packages/knowPro/src/fuzzyIndex.ts | 5 + .../knowPro/test/embeddingRoles.spec.ts | 57 +- .../memory/conversation/src/docImport.ts | 210 +++-- .../conversation/test/docImport.spec.ts | 291 +++++++ ts/packages/memory/service/README.md | 37 + ts/packages/memory/service/package.json | 1 + .../memory/service/src/benchmarkBridge.ts | 414 ++++++++++ .../memory/service/src/knowProCorpusIndex.ts | 17 +- .../service/test/benchmarkBridge.spec.ts | 189 +++++ .../service/test/markdownPersistence.spec.ts | 53 ++ ts/pnpm-lock.yaml | 14 + 34 files changed, 4535 insertions(+), 59 deletions(-) create mode 100644 ts/packages/aiclient/src/embeddingInput.ts create mode 100644 ts/packages/aiclient/test/embeddingInput.spec.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/README.md create mode 100644 ts/packages/benchmarks/src/memoryBench/cli.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/data.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/literal.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/normalize.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/protocol.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/provider.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/runner.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/scoring.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/storage.ts create mode 100644 ts/packages/benchmarks/src/memoryBench/types.ts create mode 100644 ts/packages/benchmarks/test/memoryBench.spec.ts create mode 100644 ts/packages/benchmarks/test/memoryBenchFixtures.ts create mode 100644 ts/packages/memory/conversation/test/docImport.spec.ts create mode 100644 ts/packages/memory/service/src/benchmarkBridge.ts create mode 100644 ts/packages/memory/service/test/benchmarkBridge.spec.ts diff --git a/ts/packages/aiclient/package.json b/ts/packages/aiclient/package.json index 1ecd66e644..22f723e7c6 100644 --- a/ts/packages/aiclient/package.json +++ b/ts/packages/aiclient/package.json @@ -41,6 +41,7 @@ "@typeagent/telemetry": "workspace:*", "async": "^3.2.5", "debug": "^4.4.0", + "gpt-tokenizer": "^2.9.0", "typechat": "^0.1.1" }, "devDependencies": { diff --git a/ts/packages/aiclient/src/embeddingInput.ts b/ts/packages/aiclient/src/embeddingInput.ts new file mode 100644 index 0000000000..e6473a9cf6 --- /dev/null +++ b/ts/packages/aiclient/src/embeddingInput.ts @@ -0,0 +1,27 @@ +// Copyright (c) Microsoft Corporation. +// Licensed under the MIT License. + +import { encode } from "gpt-tokenizer/encoding/cl100k_base"; + +// Keep a safety margin below the hosted embedding models' 8,192-token limit. +export const maxEmbeddingInputTokens = 8_000; + +export function countEmbeddingTokens(text: string): number { + return encode(text, { + allowedSpecial: new Set(), + disallowedSpecial: new Set(), + }).length; +} + +export function embeddingInputLimitError( + input: string | readonly string[], +): string | undefined { + const texts = typeof input === "string" ?

Smoke asks +one question per category, qualification asks all that conversation's questions, +and full asks all split questions. Documents are never truncated. + +## Resume and outputs + +Rerun the same command to reuse ready imports and saved predictions under the +same fingerprint. A judge outage does not force answer regeneration; native +citations are saved with the pending prediction. Changed data, product code, +compiled adapter, protocol or model configuration requires a fresh output root. +Python outputs are historical evidence, not compatible TypeScript checkpoints. +The v2 question-outcome policy requires a fresh output root; v1 fail-fast +checkpoints are not migrated or silently combined with it. Within the same v2 +fingerprint, scored questions and terminal failures are not retried on resume. +Infrastructure failures still preserve pending predictions for judge-only +resume without regenerating answers. + +The harness supports only BEAM's 100k, 500k, 1m and 10m splits. After the +BEAM-only scope cleanup, rebuild and prepare a fresh protocol artifact. Adapter +and protocol fingerprints change, so use a fresh output root rather than +resuming or combining previously fingerprinted results. + +- `progress.json`: active stage, exact question counts, scores, licensing and + explicit failures; previous run entries remain available. +- `/results.json`: predictions/citations, `questionFailures` with phase, + kind, error and timestamp, per-category metrics, provenance, + retrieval aliases, timings, process resource usage and run-directory size. +- `/provider-state.json`: isolated corpora, source hashes, readiness and + ingestion timings. +- `/memory`: run-owned durable memory. Personal profile corpora are unused. +- `/run.lock`: prevents concurrent writers to the same run. It is removed + on normal completion/failure. After a hard process termination, inspect its + recorded PID and remove only that specific stale lock before resuming. + +SIGINT/SIGTERM request graceful interruption at the next operation boundary; +the current service request is allowed to finish before cleanup. + +## Protocol and limits + +Answer/judge prompts match the pinned AMB protocol. BEAM reports mean +0/0.5/1 rubric compliance and `correct = score >= 0.5`, including event ordering. +The additional ordering diagnostic uses AMB semantic alignment followed by F1 +and normalized Kendall tau-b; it is not full original BEAM evaluator parity. +Configured non-Gemini models remain explicitly diagnostic, not comparable +Gemini-leaderboard submissions. + +BM25 preserves rank-bm25's formula, stable ties and 512-token `cl100k_base` +chunks, including independent UTF-8 decoding at chunk boundaries. Retrieval +aliases are retained for diagnostics; the upstream Python BM25 provider dropped +those aliases. This corrects recall reporting, not answer ranking. + +Content batches are bounded below 6 MiB before overhead; events are appended +in bounded groups with stable turn identities. Content/event RAG evidence is +bounded to 24,000 characters. Native content answers retain the product's +12-fragment / 24,000-character evidence budgets and cannot silently become +extractive answers. Native event answering is unsupported. + +Content imports remain `sourceType: "text"`; they do not bypass literal-text +handling by masquerading as Markdown. The product now uses shared lossless +DocPart splitting/packing for text, Markdown/HTML and VTT, with 7,500 +`o200k_base` extraction tokens and 8,000 `cl100k_base` embedding tokens per +input. Shared indexing and hosted embedding requests also reject oversized +inputs explicitly. This product change requires a fresh fingerprint/output +root; do not resume or combine the old oversized-input run with new results. + +Normalization preserves speaker/role, original IDs, source timestamps, session +boundaries, including sparse BEAM session anchors.

Match the outer embedding deadline to the hosted 180-second request budget so Azure 60-second quota waits do not spawn overlapping retries. Correct character-limit forwarding and add deadline, token-bound and cardinality regressions.
