[PATCH 004/128] fix: poll status=="completed" in cloud add_document (#226) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The cloud backend previously polled tree_resp["retrieval_ready"] as the ready signal. Empirically this flag is not a reliable indicator — docs can reach status=="completed" without retrieval_ready flipping, causing col.add() to wait until the 10 min timeout before giving up on otherwise-successful uploads. The cloud API's canonical ready signal is status=="completed"; switch the poll to check that instead. --- pageindex/backend/cloud.py | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/pageindex/backend/cloud.py b/pageindex/backend/cloud.py index 587a6c65b..bc42c3651 100644 --- a/pageindex/backend/cloud.py +++ b/pageindex/backend/cloud.py @@ -141,12 +141,13 @@ def add_document(self, collection: str, file_path: str) -> str: doc_id = resp["doc_id"] - # Poll until retrieval-ready + # Poll until indexing completes.

LegacyCloudAPI: close response in `finally` for both _stream_chat_response variants so abandoned iterators no longer leak the TCP connection. - PageIndexClient: emit a warning instead of silently falling back to local when api_key is the empty string, surfacing typical env-var-unset misconfig. - FakeResponse: add close()/closed to match the real requests.Response API. - Add unit coverage for stream close (both paths) and the empty-api_key warning. - Add scripts/e2e_legacy_sdk.py to smoke-test the legacy SDK contract end-to-end against api.pageindex.ai. * chore: mark legacy SDK methods with @deprecated and docstring pointers - Decorate the 12 PageIndexClient cloud-SDK compat methods with @typing_extensions.deprecated(..., category=PendingDeprecationWarning): - IDE/type-checkers render them with a strikethrough hint - runtime warnings stay silent by default (no spam for existing callers), surfaceable via `python -W default::PendingDeprecationWarning` - Add a one-line docstring on each pointing to the Collection-based equivalent. - Promote typing-extensions to a direct dependency (was transitive via litellm). --------- Co-authored-by: XinyanZhou <xinyanzhou@XinyanZhoudeMacBook-Pro.local> Co-authored-by: saccharin98 <xinyanzhou938@gmail.com> Co-authored-by: mountain <kose2livs@gmail.com> --- pageindex/__init__.py | 2 + pageindex/client.py | 146 ++++++++++++- pageindex/cloud_api.py | 265 +++++++++++++++++++++++ pageindex/errors.py | 10 +- pageindex/utils.py | 94 ++++++-- pyproject.toml | 2 + scripts/e2e_legacy_sdk.py | 94 ++++++++ tests/test_errors.py | 6 +- tests/test_legacy_sdk_contract.py | 325 ++++++++++++++++++++++++++++ tests/test_legacy_utils_contract.py | 106 +++++++++ 10 files changed, 1030 insertions(+), 20 deletions(-) create mode 100644 pageindex/cloud_api.py create mode 100644 scripts/e2e_legacy_sdk.py create mode 100644 tests/test_legacy_sdk_contract.py create mode 100644 tests/test_legacy_utils_contract.py diff --git a/pageindex/__init__.py b/pageindex/__init__.py index 64464418f..4f2418ea5 100644 --- a/pageindex/__init__.py +++ b/pageindex/__init__.py @@ -13,6 +13,7 @@ from .events import QueryEvent from .errors import ( PageIndexError, + PageIndexAPIError, CollectionNotFoundError, DocumentNotFoundError, IndexingError, @@ -32,6 +33,7 @@ "StorageEngine", "QueryEvent", "PageIndexError", + "PageIndexAPIError", "CollectionNotFoundError", "DocumentNotFoundError", "IndexingError", diff --git a/pageindex/client.py b/pageindex/client.py index 806ebb638..be2507c77 100644 --- a/pageindex/client.py +++ b/pageindex/client.py @@ -1,10 +1,21 @@ # pageindex/client.py from __future__ import annotations from pathlib import Path +from typing import Any, Iterator + +from typing_extensions import deprecated + from .collection import Collection from .config import IndexConfig +from .errors import PageIndexAPIError from .parser.protocol import DocumentParser +_LEGACY_SDK_MSG = ( + "Legacy compatibility — new code should prefer the Collection-based API " + "(PageIndexClient.collection(...))." +) +_legacy_sdk = deprecated(_LEGACY_SDK_MSG, category=PendingDeprecationWarning) + def _normalize_retrieve_model(model: str) -> str: """Preserve supported Agents SDK prefixes and route other provider paths via LiteLLM.""" @@ -39,21 +50,34 @@ class PageIndexClient: # Or use LocalClient / CloudClient for explicit mode selection """ -

Single str is normalized to [str] inside each backend; bare [] is rejected with ValueError at both layers. - wrap_with_doc_context wraps the scoped doc list in <docs>...</docs> and SCOPED_SYSTEM_PROMPT instructs the agent to treat that block as data, not instructions (defense against prompt injection via auto-generated doc_description). - _require_cloud_api now distinguishes api_key="" from api_key=None; the former gives a targeted error pointing at the empty-string vs fall-back-to-local situation when legacy SDK methods are called. - Legacy PageIndexClient.list_documents docstring spells out the return-shape difference vs collection.list_documents() to flag a silent migration footgun (paginated dict with id/name keys vs plain list[dict] with doc_id/doc_name keys). - Remove dead CloudBackend.get_agent_tools stub (not on the Backend protocol; only ever returned an empty AgentTools()) and the SYSTEM_PROMPT alias (OPEN_/SCOPED_SYSTEM_PROMPT are the explicit names now). - README quick start and streaming example now pass doc_ids; new multi-document section shows both str and list forms. - examples/demo_query_modes.py exercises all five query-mode cases (single-doc, multi-doc with/without env var, scoped single, scoped multi) for manual verification. --- README.md | 9 +- examples/demo_query_modes.py | 149 ++++++++++++++++++++++++++++++++++ pageindex/agent.py | 23 ++++-- pageindex/backend/cloud.py | 24 ++++-- pageindex/backend/local.py | 21 ++++- pageindex/backend/protocol.py | 8 +- pageindex/client.py | 29 ++++++- pageindex/collection.py | 26 ++++-- tests/test_agent.py | 16 ++-- tests/test_client.py | 26 ++++++ tests/test_cloud_backend.py | 7 +- tests/test_collection.py | 12 +++ tests/test_local_backend.py | 17 +++- 13 files changed, 322 insertions(+), 45 deletions(-) create mode 100644 examples/demo_query_modes.py diff --git a/README.md b/README.md index 03b7075bc..d0e79f6ac 100644 --- a/README.md +++ b/README.md @@ -160,7 +160,7 @@ client = PageIndexClient(model="gpt-4o-2024-11-20") col = client.collection() doc_id = col.add("path/to/your.pdf") -print(col.query("What is the main contribution?", doc_ids=[doc_id])) +print(col.query("What is the main contribution?", doc_ids=doc_id)) # Cloud mode — fully managed, no LLM key needed: # client = PageIndexClient(api_key="your-pageindex-api-key") @@ -174,7 +174,7 @@ print(col.query("What is the main contribution?", doc_ids=[doc_id])) import asyncio async def main(): - async for ev in col.query("Explain multi-head attention", stream=True): + async for ev in col.query("Explain multi-head attention", doc_ids=doc_id, stream=True): if ev.type == "answer_delta": print(ev.data, end="", flush=True) elif ev.type == "tool_call": @@ -187,10 +187,11 @@ asyncio.run(main()) ### Multi-document collections (experimental) -Passing `doc_ids` scopes the query to a specific subset of documents — this is the recommended path: +Passing `doc_ids` scopes the query to a specific subset of documents — this is the recommended path. `doc_ids` accepts a single id (`str`) or a list: ```python -col.query("Compare these two papers", doc_ids=[doc1, doc2]) +col.query("What does this paper say?", doc_ids=doc1) # single +col.query("Compare these two papers", doc_ids=[doc1, doc2]) # multi ``` Omitting `doc_ids` queries the **entire collection** and lets the agent pick which docs to read.

An unvalidated name like "../.." escaped files_dir and deleted arbitrary directories (path traversal). - legacy page_index(): restore the node_id/summary/text/description enhancements. IndexConfig now carries booleans (pydantic coerces the legacy 'yes'/'no' strings at the boundary), but page_index_main still compared `opt.if_add_node_id == 'yes'` — always False — so every enhancement was silently skipped for legacy-API callers. Conditions now branch on the booleans, matching pageindex/index/page_index.py. - LegacyCloudAPI._request: bound every request with a timeout (30s, 120s read timeout for streamed responses) so a dead connection can't hang legacy submit/poll/chat callers forever. The legacy contract tests pinned the missing timeout; updated to pin its presence instead. Adds regression tests: path-traversal rejection, 'yes'/'no' -> bool coercion, and timeout assertions.

Each thread still gets its own connection via threading.local; with the default True those closes raised ProgrammingError (silently swallowed) and leaked every worker connection. - CloudBackend.query: non-streaming chat completions now use a 300s timeout and a single attempt. The default 30s ReadTimeout fired before generation finished and the retry loop re-billed the full server-side retrieval + generation up to three times. _request gains retries/timeout overrides; the exhausted-retry path also no longer sleeps before raising. - MarkdownParser: content before the first heading (abstract/preamble) becomes a node instead of being silently dropped and unretrievable; a file with no headings at all yields a single document node instead of zero nodes (which pushed an empty page list into the pipeline). - LegacyCloudAPI.is_retrieval_ready: API failures (revoked key, network down) now propagate as PageIndexAPIError instead of reading as "not ready", which turned polling loops into infinite loops. Adds regression tests for each fix.

charset=UTF-8 Content-Transfer-Encoding: 8bit The new SDK copied the legacy indexing pipeline into pageindex/index/ instead of moving it, leaving two divergent copies of page_index.py / page_index_md.py / utils.py. They had already drifted (the legacy copy still compared IndexConfig booleans against 'yes' — a separate fix), and every pipeline change had to be applied twice. Make pageindex/index/ the single source of truth (same pattern as the LegacyCloudAPI shim for the 0.2.x cloud SDK): - pageindex/index/utils.py absorbs the 27 legacy-only helpers/classes (get_page_tokens, convert_page_to_int, ConfigLoader, PDF text helpers, ...) so it's the sole utils module. Reconciled the diverged funcs: kept the modern versions, backported the #331 get_leaf_nodes .get() fix, and restored remove_fields' max_len parameter (superset). - index/page_index*.py now import `from .utils import *`; index/legacy_utils.py (a re-export of the old top-level utils) deleted. - Top-level page_index.py / page_index_md.py / utils.py become thin re-export shims that emit PendingDeprecationWarning. The md_to_tree shim coerces legacy 'yes'/'no' string flags to bool (the canonical version is boolean-typed). - ConfigLoader no longer reads the deleted config.yaml; it builds defaults from IndexConfig (was an unconditional FileNotFoundError). - __init__.py and retrieve.py import from pageindex.index.* directly so `import pageindex` does not trip the shims. Adds tests/test_legacy_shims.py pinning the contract: clean top-level import doesn't warn, legacy submodule imports warn, symbols still resolve, shim and canonical share one implementation, the #331 fix and ConfigLoader-without-yaml both hold, and the md_to_tree coercion works.

Also raise builtin FileNotFoundError for a missing path instead of FileTypeError (which now means only "unsupported extension"). - Collection.query(doc_ids=None): the empty-collection guard now always runs — previously it was skipped once PAGEINDEX_EXPERIMENTAL_MULTIDOC was set. A single list_documents call serves both the guard and the multi-doc warning (no separate call just to decide whether to warn). - CloudBackend.query_stream: on early consumer break / GeneratorExit, signal the background SSE thread to stop and force-close the response, so it no longer drains the whole stream in the background. Adds regression tests for each (client closed, fail-fast on unknown collection, FileNotFoundError, empty-check under the multidoc env flag, single list call, early-break thread stop).

The ![image](...) references broke as soon as a query ran from a different directory. - LegacyCloudAPI: URL-encode doc_id / retrieval_id path segments (added _enc()), matching CloudBackend. An id containing '/', '?', '#' or a space previously hit the wrong endpoint or produced a malformed URL. Adds regression tests: UNIQUE enforcement, the add-race resolving to the winner, absolute image paths, and encoded legacy URLs.

charset=UTF-8 Content-Transfer-Encoding: 8bit Engineering-quality cleanups from the SDK review (no behavior change): - Return-type discoverability: add pageindex/types.py with TypedDicts (DocumentInfo, DocumentDetail, PageContent) and annotate Collection / Backend methods with them; add docstrings to every public Collection method (including the get_page_content `pages` spec). Exported from the package. Zero runtime cost — these are plain dicts. - Backend protocol as a real contract: * query_stream is an async generator, so the protocol now declares it as `def ... -> AsyncIterator[QueryEvent]` (not `async def`, which typed it as a coroutine and never matched the implementations). * custom-parser support is expressed as a runtime_checkable SupportsParserRegistration capability protocol; the client uses isinstance(...) instead of hasattr(...) duck-typing. - Parser layering: move count_tokens into a leaf module pageindex/tokens.py so parser/* imports it from there instead of reaching back into pageindex.index (a reverse dependency). index.utils re-exports it for backward compatibility. Adds tests/test_architecture.py enforcing: parser never imports index, count_tokens is a single shared leaf, the capability protocol works, both backends satisfy Backend, and the TypedDicts are exported.

Root cause — under WAL the dedup SELECT (find_document_by_hash) left a read snapshot on the connection, and the subsequent INSERT on that stale snapshot raised SQLITE_BUSY_SNAPSHOT, which busy_timeout does not retry. Fixes: - open connections in autocommit (isolation_level=None) so a SELECT never leaves a lingering read snapshot and each write is its own transaction - PRAGMA busy_timeout=10000 so concurrent writers wait for the WAL single-writer lock instead of failing immediately - an instance-level write lock serializing the fast write methods within the process (the expensive LLM indexing stays parallel) Now 8 concurrent adds of one file -> a single doc_id, zero errors.

Make the per-index max_concurrency override correct under concurrency: - Scope IndexConfig(max_concurrency=...) to the build_index call via a ContextVar (max_concurrency_scope) instead of mutating a process global. A one-off value no longer sticks as the new default, and concurrent indexing of other documents isn't affected. - Propagate the context through _run_async's worker-thread fallback so the override survives the sync-over-async thread hop. - set_max_concurrency() stays as the explicit process-wide setter. Also stop `from .utils import *` leaking a `config` name (SimpleNamespace alias) that shadowed the real pageindex.config submodule for the page_index modules; the alias is now `_config`. Adds regression tests for cap enforcement, scope stickiness/isolation, worker-thread propagation, and the config-namespace fix.

Peak in-flight LLM calls grew ~N^depth, so a deep/wide document still exhausted file descriptors (Errno 24) — the exact failure the cap was meant to prevent — while the flat summary phase was over-serialized. Naively sharing one semaphore across gather levels would instead deadlock (a parent holds a slot while awaiting children that need slots). Move the throttle to the single chokepoint every LLM call funnels through, llm_acompletion: one shared semaphore per event loop, acquired only around the litellm.acompletion network call. This gives a true global cap that composes across any nesting and can't deadlock (a parent awaiting children holds no slot). bounded_gather is gone; the call sites revert to plain asyncio.gather. Also: - Reject bool in max_concurrency validation (bool is an int subclass, so set_max_concurrency(True) / IndexConfig(max_concurrency=True) previously became Semaphore(1) and silently serialized). Shared _validate_max_concurrency + a pydantic field_validator. - Guard check_title_appearance_in_start_concurrent against an out-of-range or 0 physical_index (LLM can emit one): it was dereferenced during task construction, outside the gather's return_exceptions protection, aborting the whole build; 0 silently wrapped to the last page. Now marked 'no'. - Propagate contextvars into agent.py's worker-thread run (mirrors pipeline._run_async) so ContextVar settings stay consistent. - Tests rewritten to cover the nested case the old flat tests missed, the leaf-level throttle in llm_acompletion, bool rejection, and the out-of-range physical_index guard.

Crashes: - page_index(): snapshot args before importing IndexConfig — locals() was capturing the imported class and IndexConfig(extra='forbid') made every call raise ValidationError. - process_none_page_numbers: pop('page', None) instead of del (a TOC item without 'page' raised KeyError mid-pipeline). - pipeline._run_async: guard only the loop detection, not the run, so a real RuntimeError from the coroutine isn't masked as "asyncio.run() cannot be called from a running event loop". Silent-wrong / robustness: - LocalBackend.get_document_structure and the agent get_document / get_document_structure tools now surface a missing doc (raise / error-JSON) instead of returning empty, matching get_page_content and the cloud backend. - cloud delete_collection drops the cached folder_id. - cloud query raises on an empty collection instead of POSTing doc_id:[]. - LocalClient skips the API-key check for keyless providers (ollama, lm_studio, …) so keyless LiteLLM models aren't rejected at construction. Compat / cleanup: - md_to_tree coerces legacy 'yes'/'no' string flags (a bare 'no' was truthy). - FileTypeError also subclasses ValueError (0.2.x raised ValueError). - _validate_llm_provider no longer mutates global litellm.model_cost_map_url. - __all__ re-includes legacy exports (page_index, md_to_tree, get_*). - Rewrite examples/agentic_vectorless_rag_demo.py to the Collection API and use the in-repo attention.pdf (the old workspace=/client.index/client.documents API no longer exists).

Most trace back to one root cause: the build_index() text-stripping fix (8f536cb) correctly stopped Markdown from leaking full text by default, but broke every path that assumed text could be re-read later. Correctness: - LocalBackend._fill_node_text (get_document(include_text=True)) only handled PDF's start_index/end_index convention; Markdown nodes use line_num and got silently empty text. Now handles both. - get_page_content's Markdown fallback (triggered when a StorageEngine legitimately returns None from get_pages()) read from the now-text-stripped structure. It now re-derives from the source file, mirroring the PDF fallback, so it no longer depends on structure text at all. - add_document's PDF-only text-stripping branch (with the stale "markdown needs text in structure for fallback retrieval" comment) is now dead/wrong since build_index() already applies if_add_node_text uniformly — removed. - _validate_llm_provider's keyless-provider allowlist was missing several local LiteLLM providers (xinference, llamafile, triton, oobabooga, openai_like, docker_model_runner, custom, custom_openai, petals) that need no API key just like ollama/lm_studio; expanded. - The three agent-tool closures (get_document, get_document_structure, get_page_content) had three different not-found patterns; two bypassed the backend's DocumentNotFoundError entirely. Extracted LocalBackend. _require_document as the single existence check every method/tool now uses. - examples/agentic_vectorless_rag_demo.py's hand-rolled Agent() didn't apply the litellm/ prefix normalization the SDK does internally, so its own documented "any LiteLLM provider" claim broke for non-openai models. - cloud delete_collection's cache eviction removed the "folders unavailable" None sentinel too, forcing a wasted re-fetch; now only pops on a real id. Cleanup / altitude: - build_index() skips the remove_structure_text walk entirely when text was never added (content_based + if_add_node_summary=False + if_add_node_text= False) instead of a guaranteed no-op tree walk. - page_index()'s locals()-capture-as-kwargs (fragile by construction) replaced with an explicit dict of the named parameters. - run_pageindex.py's _cli_bool and the page_index_md.py legacy shim's _coerce_bool were duplicate, diverging implementations; both now bind directly to the canonical pageindex.index.page_index_md._coerce_bool. - retrieve.py's _get_md_page_content delegated its own traversal instead of calling the canonical get_md_page_content; now a one-line delegation. - FileTypeError's docstring now calls out the except-ordering gotcha from also subclassing ValueError. 17 new regression tests (tests/test_review_fixes_2.py) plus 2 updated in tests/test_legacy_shims.py for the simplified md_to_tree shim. Full suite: 210 passed, 2 skipped.

Mirrors the OpenKnowledgeBase publish flow, but keeps poetry-core as the build backend and injects the version in CI rather than switching to VCS-driven versioning, so contributors' local builds are unaffected. Requires one-time setup: a PyPI Trusted Publisher on the pageindex project (repo VectifyAI/PageIndex, workflow publish.yml, environment pypi) and a GitHub Environment named pypi.

Deterministic per-field transform, doesn't touch the (cacheable) static system prompt. - ConfigLoader.load() (legacy 0.2.x compat) now routes merged overrides through IndexConfig before returning, so a legacy 'no' string gets pydantic's bool coercion instead of surviving as a truthy non-empty string — page_index_main's bare `if opt.if_add_node_summary:` checks (changed from `== 'yes'` elsewhere in this PR) were silently inverting caller intent and firing unwanted billed LLM calls. - verify_toc, process_large_node_recursively, tree_parser, generate_summaries_for_structure, generate_summaries_for_structure_md: added return_exceptions=True to their asyncio.gather calls (llm_completion/ llm_acompletion raise RuntimeError on retry exhaustion, added earlier in this PR), each with a degrade path matching the pattern already used by sibling hardened gathers in the same files. One transient LLM failure no longer aborts the whole document's indexing. - _llm_semaphore is now a true process-wide ceiling (threading.Semaphore, shared across every thread/event loop) instead of one asyncio.Semaphore per event loop -- concurrently indexing N documents on N threads no longer multiplies the effective cap by N. A max_concurrency_scope() override is layered as a second, nested, per-loop restriction that can only tighten the effective cap within the ceiling, never widen past it. - set_llm_params() mutated a bare process-wide dict with no per-call isolation, unlike max_concurrency which already had ContextVar scoping. Added llm_params_scope() (mirrors max_concurrency_scope) + IndexConfig.llm_params, wired into build_index() the same way max_concurrency already was, so concurrent indexing jobs with different llm kwargs don't leak into each other. Adds regression tests for all five. Full suite: 221 passed, 2 skipped (one pre-existing, unrelated flaky cloud-streaming test intermittently fails on rerun; confirmed independent of this change).

Fixed to `pix.n - pix.alpha >= 4` (correctly converts CMYK, leaves RGBA untouched). - pipeline.py: detect_strategy([]) (an empty/whitespace-only source file) returned "content_based", routing into the PDF-oriented TOC-detection pipeline -- wasting a real LLM call before raising IndexingError. Empty node lists now route to level_based, whose build_tree_from_levels([]) returns an empty structure instantly with zero LLM calls. - page_index.py (shim): pageindex/__init__.py binds the canonical `page_index` function as the package attribute, but this file is ALSO a real submodule of the same name -- importing it anywhere (import machinery, unconditional) overwrites that attribute with the module object, breaking `from pageindex import page_index; page_index(x)` for the rest of the process. Made the shim module itself callable (delegates to the real function via a ModuleType subclass), so whichever object ends up in that slot is callable regardless of import order. - storage/sqlite.py: create_collection let a raw sqlite3.IntegrityError escape on a duplicate name (new CollectionAlreadyExistsError); the collections table's CHECK constraint only validated the name's first character (GLOB '*' is a wildcard, not a regex quantifier over the preceding class) -- fixed to validate the whole string, and SQLiteStorage now also validates in Python (it's a public StorageEngine usable directly, bypassing LocalBackend's own check). - tests/test_review_fixes_2.py: two tests used a ContentNode with no `level` set, so build_index took the content_based path and made real (retried, slow, and -- with a valid key -- billable) LLM calls instead of testing the text-stripping logic they claimed to. Mocked out _content_based_pipeline. - retrieve.py: _parse_pages/_get_pdf_page_content were independent copies of the canonical parse_pages/get_pdf_page_content that had already drifted (missing the p>=1 filter and 1000-page DoS cap) -- delegate to canonical now, so the legacy pageindex.get_page_content path can't silently regress again. - parser/markdown.py: a leading UTF-8 BOM broke first-header detection (not whitespace, .strip() doesn't remove it) -- decode utf-8-sig. Only backtick fences were recognized as code blocks, so a '#'-prefixed line inside a ~~~-fenced block (valid CommonMark) was misparsed as a heading -- recognize both fence styles. - run_pageindex.py: --if-thinning wasn't migrated to the bare-flag + legacy-yes/no convention the other four --if-add-* flags got; bare usage raised an argparse error and it never went through the shared coercion. - types.py: DocumentDetail's `structure` field was inside the class's total=False body, so TypedDict rules made it optional even though every backend always populates it. Split into a required base class. Adds regression tests for all of the above. Full suite: 244 passed, 2 skipped (one pre-existing, unrelated flaky cloud-streaming test).

Added [tool.poetry.group.dev.dependencies]. pytest-asyncio, though installed locally, isn't actually required: no test in this suite uses `async def test_...` / @pytest.mark.asyncio, they all drive async code via plain asyncio.run() inside sync test functions — so only pytest itself is declared.

It introduces no additional memory overhead during vanilla training but incurs communication and memory overhead in distributed training due to the need to retain and transmit layer outputs across stages.

The update hl=\nhl−1+fl−1(hl−1)is widely understood as agradient highwaythat lets gradients bypass transformations via identity\nmappings, enabling stable training at depth. Yet residuals also play a second role that has received less attention.\nUnrolling the recurrence shows that every layer receives the same uniformly-weighted sum of all prior layer outputs;\nresiduals define how information aggregates across depth. Unlike sequence mixing and expert routing, which now\nemploy learnable input-dependent weighting [53, 20, 9], this depth-wise aggregation remains governed by fixed unit\nweights, with no mechanism to selectively emphasize or suppress individual layer contributions.\nIn practice, PreNorm [60] has become the dominant paradigm, yet its unweighted accumulation causes hidden-state\nmagnitudes to grow as O(L) with depth, progressively diluting each layer’s relative contribution [27]. Early-layer\ninformation is buried and cannot be selectively retrieved; empirically, a significant fraction of layers can be pruned with\nminimal loss [11]. Recent efforts such as scaled residual paths [54] and multi-stream recurrences [72] remain bound to\nthe additive recurrence, while methods that do introduce cross-layer access [36, 56] are difficult to scale. The situation\nparallels the challenges that recurrent neural networks (RNNs) faced over the sequence dimension before attention\nmechanism provided an alternative.\nWe observe a formal duality between depth-wise accumulation and the sequential recurrence in RNNs. Building\non this duality, we proposeAttention Residuals (AttnRes), which replaces the fixed accumulation hl=P\nivi\nwithhl=P\niαi→l·vi, where αi→laresoftmax attention weights computed from a single learned pseudo-query\nwl∈Rdper layer. This lightweight mechanism enables selective, content-aware retrieval across depth with only one\nd-dimensional vector per layer. Indeed, standard residual connections and prior recurrence-based variants can all be\nshown to perform depth-wiselinearattention; AttnRes generalizes them to depth-wise softmax attention, completing\nfor depth the same linear-to-softmaxtransition that proved transformative over sequences (§6.2, §6.1).\nIn standard training, Full AttnRes adds negligible overhead, since the layer outputs it requires are already retained for\nbackpropagation. At scale, however, activation recomputation and pipeline parallelism are routinely employed, and these\nactivations must now be explicitly preserved and communicated across pipeline stages. We introduceBlock AttnResto\nmaintain efficiency in this regime: layers are partitioned into Nblocks, each reduced to a single representation via\nstandard residuals, with cross-block attention applied only over the Nblock-level summaries. This brings both memory\nand communication down to O(Nd) , and together with infrastructure optimizations (§4), Block AttnRes serves as a\ndrop-in replacement for standard residual connections with marginal training cost and negligible inference latency\noverhead.\nScaling law experiments confirm that AttnRes consistently outperforms the baseline across compute budgets, with\nBlock AttnRes matching the loss of a baseline trained with 1.25× more compute. We further integrate AttnRes into\nthe Kimi Linear architecture [69] (48B total / 3B activated parameters) and pre-train on 1.4T tokens. Analysis of\nthe resulting training dynamics reveals that AttnRes mitigates PreNorm dilution, with output magnitudes remaining\nbounded across depth and gradient norms distributing more uniformly across layers. On downstream benchmarks, our\nfinal model improves over the baseline across all evaluated tasks.\nContributions\n•Attention Residuals.We propose AttnRes, which replaces fixed residual accumulation with learned softmax\nattention over depth, and its scalable variant Block AttnRes that reduces memory and communication from O(Ld) to\nO(Nd) . Through a unified structured-matrix analysis, we show that standard residuals and prior recurrence-based\nvariants correspond to depth-wiselinearattention, while AttnRes performs depth-wisesoftmaxattention.\n•Infrastructure for scale.We develop system optimizations that make Block AttnRes practical and efficient at scale,\nincluding cross-stage caching that eliminates redundant transfers under pipeline parallelism and a two-phase inference\nstrategy that amortizes cross-block attention via online softmax [31]. The resulting training overhead is marginal,\nand the inference latency overhead is less than 2% on typical inference workloads.\n•Comprehensive evaluation and analysis.We validate AttnRes through scaling law experiments, component\nablations, and downstream benchmarks on a 48B-parameter model pre-trained on 1.4T tokens, demonstrating\nconsistent improvements over standard residual connections.

For clarity, we write formulas for a single token: hl∈Rddenotes the hidden state\nentering layer l, where l∈ {1, . . . , L} is the layer index and Lis the total number of layers. The token embedding is h1.\nThe function flrepresents the transformation applied by layer l. In Transformer models, we treat each self-attention or\nMLP as an individuallayer.\n2.1 Training Deep Networks via Residuals\nResidual Learning.Residual learning [12] proves to be a critical technique in training deep networks as it allows\ngradients to bypass transformations. Specifically, each layer updates the hidden state as:\nhl=hl−1+fl−1(hl−1)\nExpanding this recurrence, the hidden state at layer lis the sum of the embedding and all preceding layer outputs:\nhl=h 1+Pl−1\ni=1fi(hi). The key insight behind residual connections isidentity mapping: each layer preserves a direct\npath for both information and gradients to flow unchanged. During back-propagation, the gradient with respect to an\nintermediate hidden state is:\n∂L\n∂hl=∂L\n∂hL·L−1Y\nj=l\u0012\nI+∂fj\n∂hj\u0013\nExpanding this product yields Iplus higher-order terms involving the layer Jacobians ∂fj/∂hj. The identity term is\nalways preserved, providing a direct gradient path from the loss to any layer regardless of depth.\nGeneralizing Residuals.While effective, the fixed unit coefficients in the residual update treat every layer’s con-\ntribution uniformly, offering no mechanism to adapt the mixing across depth. Highway networks [45] relax this by\nintroducing learned element-wise gates:\nhl= (1−g l)⊙h l−1+gl⊙fl−1(hl−1)\nwhere gl∈[0,1]dinterpolates between the transformation and the identity path. More generally, both are instances\nof a weighted recurrence hl=α l·hl−1+βl·fl−1(hl−1), with residual setting αl=βl=1and Highway setting\nαl=1−g l, βl=gl.\nLimitations.Whether fixed or gated, both approaches share a fundamental constraint: each layer can only access\nits immediate input hl−1, a single compressed state that conflates all earlier layer outputs, rather than the individual\noutputs themselves. This entails several limitations: (1)no selective access: different layer types (e.g., attention vs.\nMLP) receive the same aggregated state, despite potentially benefiting from different weightings; (2)irreversible loss:\ninformation lost through aggregation cannot be selectively recovered in deeper layers; and (3)output growth: later\nlayers learn increasingly larger outputs to gain influence over the accumulated residual, which can destabilize training.\nThese limitations motivate a mechanism that lets each layer selectively aggregate information from all preceding layers.\n3 Attention Residuals: A Unified View of Time and Depth\nThe limitations discussed above are reminiscent of similar bottlenecks in sequence modeling, suggesting that we seek\nsimilar solutions for the depth dimension.\nThe Duality of Time and Depth.Like RNNs over time, residual connections compress all prior information into a\nsingle state hlover depth. For sequence modeling, the Transformer improved upon RNNs by replacing recurrence with\nattention [3, 52], allowing each position to selectively access all previous positions with data-dependent weights. We\npropose the same methodology for depth:\nhl=α 0→l·h1+l−1X\ni=1αi→l·fi(hi)(1)\nwhere αi→lare layer-specific attention weights satisfyingPl−1\ni=0αi→l= 1. Unlike sequence length (which can reach\nmillions of tokens), network depth is typically modest ( L <1000 ), making O(L2)attention over depth computationally\nfeasible.

The input to layerlis then:\nhl=l−1X\ni=0αi→l·vi (4)\nWe call this formfull attention residuals. For each token, Full AttnRes requires O(L2d)arithmetic and O(Ld) memory\nto store layer outputs. Since depth is far smaller than sequence length, the arithmetic cost is modest.\nOverhead.The O(Ld) memory overlaps entirely with the activations already retained for backpropagation, so Full\nAttnRes introduces no additional memory overhead in vanilla training. At scale, however, activation recomputation and\npipeline parallelism are widely adopted: layer outputs that would otherwise be freed and recomputed must now be kept\nalive for all subsequent layers, and under pipeline parallelism each must further be transmitted across stage boundaries.\nBoth the memory and communication overhead then grow asO(Ld).\nBlockwise optimization.A deliberate design choice in Full AttnRes is that thepseudo-query wlis a learned parameter\ndecoupled from the layer’s forward computation. This independence means that attention weights for any group of\nlayers can be computed in parallel without waiting for their sequential outputs, and in particular permits grouping the L\nlayers into Nblocks of Slayers each and batching the attention computation within each block, reducing per-layer\nmemory I/O from O(Ld) toO((S+N)d) (we defer the detailed two-phase strategy to §4). Under current distributed\ntraining regimes, however, the dominant cost is not local memory bandwidth but cross-stage communication under\npipeline parallelism: every layer output must still be transmitted between stages, and this O(Ld) communication\noverhead cannot be alleviated by local batching. This motivates the Block AttnRes variant introduced below, which\nreduces the number of cross-stage representations from LtoN. We anticipate that future interconnect improvements\nwill make the fullO(Ld)communication practical, fully realizing the potential of Full AttnRes.\n3.2 Block Attention Residuals\nWe proposeBlock Attention Residuals, which partitions the Llayers into Nblocks: within each block, the layer outputs\nare reduced to a single representation via summation, and across blocks, we apply full attention over only Nblock-level\nrepresentations and the token embedding. This reduces both memory and communication overhead from O(Ld) to\nO(Nd).\nIntra-Block Accumulation.Specifically, we divide the Llayers into Nblocks of S=L/N layers each, assuming\nLis divisible by N; otherwise, the last block contains the remaining LmodN layers. Let Bndenote the set of layer\nindices in blockn(n= 1, . . . , N). To form a block, we sum all of its layer outputs:\nbn=X\nj∈Bnfj(hj)(5)\nWe further denote bi\nnas the partial sum over the first ilayers in Bn, so that bn=bS\nn. When Lis not divisible by N,\nthe final partial sum is taken as the last block’s representation. As in Full AttnRes, the RMSNorm inside ϕprevents\nmagnitude differences between complete blocks and partial sums from biasing the attention weights.\n4" - }, - { - "page": 5, - "content": "Attention ResidualsTECHNICALREPORT\n1 def block_attn_res(blocks: list[Tensor], partial_block: Tensor, proj: Linear, norm: RMSNorm) -> Tensor:\n2 \"\"\"\n3 Inter-block attention: attend over block reps + partial sum.\n4 blocks:\n5 N tensors of shape [B, T, D]: completed block representations for each previous block\n6 partial_block:\n7 [B, T, D]: intra-block partial sum (b_n^i)\n8 \"\"\"\n9 V = torch.stack(blocks + [partial_block]) # [N+1, B, T, D]\n10 K = norm(V)\n11 logits = torch.einsum('d, n b t d -> n b t', proj.weight.squeeze(), K)\n12 h = torch.einsum('n b t, n b t d -> b t d', logits.softmax(0), V)\n13 return h\n14\n15 def forward(self, blocks: list[Tensor], hidden_states: Tensor) -> tuple[list[Tensor], Tensor]:\n16 partial_block = hidden_states\n17 # apply block attnres before attn\n18 # blocks already include token embedding\n19 h = block_attn_res(blocks, partial_block, self.attn_res_proj, self.attn_res_norm)\n20\n21 # if reaches block boundary, start new block\n22 # block_size counts ATTN + MLP; each transformer layer has 2\n23 if self.layer_number % (self.block_size // 2) == 0:\n24 blocks.append(partial_block)\n25 partial_block = None\n26\n27 # self-attention layer\n28 attn_out = self.attn(self.attn_norm(h))\n29 partial_block = partial_block + attn_out if partial_block is not None else attn_out\n30\n31 # apply block attnres before MLP\n32 h = block_attn_res(blocks, partial_block, self.mlp_res_proj, self.mlp_res_norm)\n33\n34 # MLP layer\n35 mlp_out = self.mlp(self.mlp_norm(h))\n36 partial_block = partial_block + mlp_out\n37\n38 return blocks, partial_block\nFigure 2: PyTorch-style pseudo code for Block Attention Residuals. block_attn_res computes softmax attention over block\nrepresentations using a learned pseudo-query wl;forward is a single-layer pass that maintains partial_block (bi\nn, intra-block\nresidual) andblocks([b 0, . . . ,b n−1], inter-block history).\nInter-Block Attention.In Full AttnRes, the input to layer lis computed by attending over all outputs up to fl−1(hl−1).\nThe block-wise variant replaces these individual outputs with block representations, defining b0=h 1so that the token\nembedding is always included as a source. For thei-th layer in blockn, the value matrix is:\nV=\u001a[b0,b1, . . . ,b n−1]⊤ifi= 1(first layer of blockn)\n[b0,b1, . . . ,b n−1,bi−1\nn]⊤ifi≥2(subsequent layers)(6)\nKeys and attention weights follow Eq. 3 and Eq. 2. The input of the very first layer of the network is the token\nembeddings, i.e. b0=h 1. In each block, the first layer receives the previous block representations and the token\nembeddings, and the subsequent layers additionally attend to the partial sum bi−1\nn. The final output layer aggregates all\nNblock representations. Fig. 2 provides PyTorch-style pseudocode for Block AttnRes.\nEfficiency.Since each layer now attends over Nblock representations rather than Lindividual outputs, memory\nreduces from O(L) toO(N) and computation from O(L2)toO(N2). The block count Ninterpolates between two\nextremes: N=L recovers Full AttnRes, while N= 1 reduces to standard residual connections with the embedding\nisolated as b0. Empirically, we find that N≈8 recovers most of the benefit across model scales, requiring only eight\nstored hidden states per token (see § 5).\nBeyond memory and computation, the block structure also benefits inference latency: block boundaries define the\ndispatch granularity for the blockwise optimization described in §3, and the fixed block count Nbounds the KV cache\nsize. The parallel inter-block results are merged with the sequential intra-block partial sums via online softmax [31],\npreserving exact equivalence (§4).\n4 Infrastructure Design\nBlock AttnRes introduces additional system challenges compared to standard residual connections.

During inference, repeated access to accumulated block representations increases latency, while\nlong-context prefilling amplifies the memory cost of caching block representations. We address these challenges with\ncross-stage caching in training, and with a two-phase computation strategy together with a memory-efficient prefilling\nscheme in inference.\n4.1 Training\nFor small-scale training, AttnRes adds a tiny computation overhead and no extra memory usage, as the activations\nneed to be saved for backpropagation regardless. Under large-scale distributed training, pipeline parallelism poses the\nprimary infrastructure challenge for AttnRes. Full AttnRes requires all Llayer outputs to be transmitted across stages;\nBlock AttnRes reduces this to Nblock representations, and the optimizations below further minimize the remaining\noverhead.\nPipeline communication.With standard residual connections, pipeline parallelism [18] transfers a fixed-size hidden\nstate between adjacent stages, independent of pipeline depth. Block AttnRes requires all accumulated block representa-\ntions at each stage for inter-block attention, and naïvely transmitting the full history at every transition incurs redundant\ncommunication.\nConsider an interleaved pipeline schedule [33] with Pphysical stages and Vvirtual stages per physical stage. For\nsimplicity, assume each physical stage produces on average Npblock representations of dimension dper token.1With\nC=PV total chunks (each physical stage in each virtual stage), the j-th chunk accumulates jNpblocks. Naïvely\ntransmitting all accumulated blocks at every transition incurs per-token communication cost:\nComm naïve=C−1X\nj=1jNp·d=C(C−1)\n2Npd.(7)\nCross-stage caching.Since each physical stage processes multiple virtual stages in succession, we can eliminate\nthis redundancy by caching blocks locally: blocks received during earlier virtual stages remain in local memory and\nneed not be re-transmitted. The first virtual stage ( v= 1 ) has no cache and accumulates normally; for v≥2 , each\ntransition conveys only the ∼PN pincremental blocks accumulated since the receiver’s corresponding chunk in the\nprevious virtual stage. Total communication reduces to:\nComm cached =P(P−1)\n2Npd\n|{z}\nfirst virtual stage+ (V−1)P2Npd|{z }\nsubsequent virtual stages.(8)\nCaching reduces peak per-transition cost from O(C) toO(P) , aV× improvement that enables full overlap with\ncomputation during steady-state 1F1B. The backward pass benefits from the same scheme. Fig. 3 illustrates this\noptimization withP=4andV=2: for the second virtual stage, caching eliminates 6 redundant block transmissions.\n1In practice, block boundaries need not align with physical stage boundaries. For example, in Fig. 3, each block spans two\nphysical stages, so only every other transition involves a newly completed block.\n6" - }, - { - "page": 7, - "content": "Attention ResidualsTECHNICALREPORT\nAlgorithm 1:Two-phase computation for blockn\nInput:Pseudo queries{w l}l∈Bn, block representations{b 0, . . . ,b n−1}\n/* Phase 1: Parallel inter-block attention */\n1Q←[w l]l∈Bn //[S, d]\n2K,V←[b 0;. . .;b n−1]//[n, d]\n3{o(1)\nl, m(1)\nl, ℓ(1)\nl}l∈Bn←ATTNWITHSTATS(Q,K,V)// Return LSE\n4\n/* Phase 2: Sequential intra-block attention + Onlinesoftmaxmerge */\n5i←0\n6forl∈ B ndo\n7ifi= 0then\n8h l←o(1)\nl/ℓ(1)\nl// Inter-block only\n9else\n10o(2)\nl, m(2)\nl, ℓ(2)\nl←ATTNWITHSTATS(w l,bi\nn,bi\nn)// Intra-block\n11m l←max(m(1)\nl, m(2)\nl)\n12h l←em(1)\nl−mlo(1)\nl+em(2)\nl−mlo(2)\nl\nem(1)\nl−mlℓ(1)\nl+em(2)\nl−mlℓ(2)\nl// Online softmax merge\n13i←i+ 1\n14bi\nn←bi−1\nn+fl(hl)// Update partial sum;b0\nn:=0\n15return{h l}l∈Bn\nMemory overhead.With cross-stage caching, each block is stored exactly once across all Vvirtual stages, which\nbecomes negligible relative to standard per-layer activation cache.

For Full AttnRes, this reduces per-layer I/O from O(Ld) toO((S+N)d) (detailed derivation shown in\nAppendix B); Block AttnRes further reduces the stored representations from LtoN, since each block is compressed\ninto a single vector. In what follows, we focus on Block AttnRes and detail the two-phase computation strategy together\nwith a sequence-sharded prefilling scheme for long-context inputs.\nTwo-phase computation strategy.The layer-wise attention computation of Block AttnRes resembles autoregressive\ndecoding, where block representations serve as a shared KV cache reused across layers. A naïve implementation\ncomputes the attention residual at every layer, each requiring a full pass over all preceding blocks, resulting in O(L·N)\nmemory accesses. Since the pseudo-query vectors are decoupled from the forward computation (§3), all S=L/N\nqueries within a block can be batched into a single matrix multiplication, amortizing memory access from Sreads to 1.\nAlgorithm 1 instantiates a two-phase computation strategy exploiting this property.\n•Phase 1computes inter-block attention for all Slayers simultaneously via a single batched query against the cached\nblock representations, returning both outputs and softmax statistics (max and log-sum-exp). This amortizes the\nmemory access cost, reducing reads fromStimes to just once per block.\n•Phase 2computes intra-block attention sequentially for each layer using the evolving partial sum, then merges with\nPhase 1 outputs through online softmax [31]. Because the online- softmax merge is elementwise, this phase naturally\nadmits kernel fusion with surrounding operations, further reducing I/O overhead.\nWith the two-phase design, Phase 2 preserves an I/O footprint similar to that of standard residual connections, whereas\nthe main additional cost arises from Phase 1 inter-block attention. Because these inter-block reads are amortized across\n7" - }, - { - "page": 8, - "content": "Attention ResidualsTECHNICALREPORT\nall layers in a block through batching, the total per-layer memory access cost remains only (N\nS+ 3)d reads and 2d\nwrites (Table 1). This is substantially lower than the residual-stream I/O of prior residual generalizations such as (m)HC\nunder typical settings. In practice, Phase 1 can also partially overlap with the computation of the first layer in the block,\nfurther reducing its wall-clock impact. As a result, the end-to-end inference latency overhead is less than 2% on typical\ninference workloads.\nTable 1: Memory access cost per token per layer incurred by the residual mechanism under each scheme.

We mitigate this by sharding these representations along\nthe sequence dimension across Ptensor-parallel devices, allowing Phase 1 to execute independently on local sequence\nshards. The Phase 2 online- softmax merge then integrates into the standard TP all-reduce communication path: the\noutput is reduce-scattered, merged locally, and reconstructed via all-gather, naturally admitting kernel fusion with\noperations like RMSNorm . This reduces the per-device memory footprint to N·(T/P)·d —lowering the 128K-context\nexample from 15 GB to roughly 1.9 GB per device. Combined with chunked prefill (e.g., 16K chunk size), the overhead\nfurther reduces to under 0.3 GB per device.\n5 Experiments\nArchitecture Details.Our architecture is identical to Kimi Linear [69], a Mixture-of-Experts (MoE) Transformer\nfollowing the Moonlight [28] / DeepSeek-V3 [9] design, which interleaves Kimi Delta Attention (KDA) and Multi-Head\nLatent Attention (MLA) layers in a 3:1 ratio, each followed by an MoE feed-forward layer. The only modification is the\naddition of AttnRes to the residual connections; all other components (model depth, hidden dimensions, expert routing,\nand MLP structure) remain unchanged. AttnRes introduces only one RMSNorm and one pseudo-query vector wl∈Rd\nper layer, amounting to a negligible fraction of the total parameter count. Crucially, all pseudo-query vectors must be\ninitialized to zero. This ensures that the initial attention weights αi→lare uniform across source layers, which reduces\nAttnRes to an equal-weight average at the start of training and prevents training volatility, as we validated empirically.\n5.1 Scaling Laws\nWe sweep five model sizes (Table 2) and train three variants per size: a PreNorm baseline, Full AttnRes, and Block\nAttnRes with ≈8blocks. They are trained with an 8192-token context window and a cosine learning rate schedule.\nWithin each scaling law size group, all variants share identical hyperparameters selected under the baseline to ensure\nfair comparison; this setup intentionally favors the baseline and thus makes the comparison conservative. Following\nstandard practice, we fit power-law curves of the form L=A×C−α[22, 15], where Lis validation loss and Cis\ncompute measured in PFLOP/s-days.\nScaling Behavior.Fig. 4 presents the fitted scaling curves.

Training of the final model proceeds in two stages: (i) a WSD pre-training phase\non 1T tokens, followed by (ii) a mid-training phase on ≈400B high-quality tokens, following the annealing recipe of\nMoonlight [28].\nAfter mid-training, we continue training with progressively longer sequence length of 32K tokens. Since our architecture\nuses hybrid KDA/MLA attention [69], where MLA operates without positional encodings (NoPE) [61], context extension\nrequires no modifications such as YaRN [37] or attention temperature rescaling.\n9" - }, - { - "page": 10, - "content": "Attention ResidualsTECHNICALREPORT\n20k 40k 60k 80k 100k1.21.31.41.5\nStep(a) Validation Loss\nBaseline\nBlock AttnRes\n0 10 20051015\nTransformer Block Index(b) Output Magnitude\n0 10 200123\nTransformer Block Index(c) Gradient Magnitude (×10−5)\nFigure 5: Training dynamics of Baseline and Block AttnRes.(a)Validation loss during training.(b)Each transformer block’s output\nmagnitude at the end of training.(c)Each transformer block’s gradient magnitude.\nTraining dynamics.We compare the training dynamics of our final Baseline and Block AttnRes models over 1T\ntokens in Fig. 5.\n•Validation loss:AttnRes achieves consistently lower validation loss throughout training, with the gap widening\nduring the decay phase and resulting in a notably lower final loss.\n•Output magnitude:The Baseline suffers from the PreNorm dilution problem [60, 27]: as hidden-state magnitudes\ngrow monotonically with depth, deeper layers are compelled to learn increasingly large outputs from fixed-scale\nnormalized inputs to remain influential.

All\nmodels share identical hyperparameters and compute budget.\nComparison with prior methods.We compare AttnRes against the PreNorm baseline (loss 1.766) and two rep-\nresentative methods that generalize residual connections. DenseFormer [36] grants each layer access to all previous\noutputs but combines them with fixed, input-independent scalar coefficients; it shows no gain over the baseline (1.767),\nhighlighting the importance of input-dependent weighting. mHC [59] introduces input dependence through mparallel\nstreams with learned mixing matrices, improving to 1.747. AttnRes takes this further with explicit content-dependent\nselection via softmax attention: Full AttnRes achieves 1.737 and Block AttnRes 1.746, outperforming both methods\nwith only a single query vector per layer.\nCross-layer access.We compare three granularities of cross-layer access. Full AttnRes follows directly from the\ntime–depth duality (§ 3), applying attention over all previous layers, and achieves the lowest loss (1.737). A simple\nway to reduce its memory cost is sliding-window aggregation (SWA), which retains only the most recent W=8 layer\noutputs plus the token embedding; it improves over baseline (1.764) but falls well short of both Full and Block AttnRes,\nsuggesting that selectively accessing distant layers matters more than attending to many nearby ones.\nBlock AttnRes offers a better trade-off: with block size S=4 it reaches 1.746 while keeping memory overhead constant\nper layer.

Loss\ndegrades gracefully as Sgrows, with S=2,4,8 all landing near 1.746 while larger blocks ( S=16,32 ) move toward\nbaseline. In practice, we fix the number of blocks to ≈8for infrastructure efficiency (§ 4). As future hardware alleviates\nmemory capacity constraints, adopting finer-grained block sizes or Full AttnRes represents a natural pathway to further\nimprove performance.\n11" - }, - { - "page": 12, - "content": "Attention ResidualsTECHNICALREPORT\n15 30 45 60 750.30.40.50.60.7 2.017 1.909 1.875 1.851 1.858\n1.990 1.902 1.862 1.852 1.862\n1.973 1.883 1.859 1.849 1.854\n1.952 1.868 1.850 1.849 1.857\n1.926 1.857 1.851 1.858 1.847\ndmodel/LbH/L b\n(a) Baseline15 30 45 60 751.954 1.890 1.843 1.828 1.824\n1.931 1.863 1.830 1.817 1.818\n1.917 1.841 1.819 1.812 1.817\n1.893 1.823 1.815 1.813 1.813\n1.877 1.816 1.820 1.806 1.802\ndmodel/Lb\n1.841.881.921.962\n(b) Attention Residuals\nFigure 7: Architecture sweep under fixed compute ( ≈6.5×1019FLOPs, ≈2.3×108active parameters). Each cell reports\nvalidation loss for a (dmodel/Lb, H/L b)configuration, where Lb=L/2 is the number of Transformer blocks; the star marks the\noptimum.\nComponent design.We further ablate individual components of the attention mechanism:\n•Input-dependent query.A natural extension is to make the query input-dependent by projecting it from the current\nhidden state. This further lowers loss to 1.731, but introduces a d×d projection per layer and requires sequential\nmemory access during decoding, so we default to the learned query.\n•Input-independent mixing.We removed the query and key and replaced them with learnable, input-independent\nscalars to weigh previous layers, which hurts performance (1.749 vs. 1.737).\n•softmax vs.sigmoid .Replacing softmax withsigmoid degrades performance (1.741). We attribute this to softmax ’s\ncompetitive normalization, which forces sharper selection among sources.\n•Multihead attention.We test per-head depth aggregation ( H=16 ) on Block AttnRes, allowing different channel\ngroups to attend to different source layers. This hurts performance (1.752 vs. 1.746), indicating that the optimal\ndepth-wise mixture is largely uniform across channels: when a layer’s output is relevant, it is relevant as a whole.\n•RMSNorm on keys.Removing RMSNorm degrades both Full AttnRes (1.743) and Block AttnRes (1.750). For\nFull AttnRes, it prevents individual layers with naturally larger outputs from dominating the softmax . This becomes\neven more critical for Block AttnRes, as block-level representations accumulate over more layers and can develop\nlarge magnitude differences;RMSNormprevents these from biasing the attention weights.\n5.4 Analysis\n5.4.1 Optimal Architecture\nTo understand how AttnRes reshapes optimal architectural scaling, we perform a controlled capacity reallocation\nstudy under a fixed compute and parameter budget. Our central question is whether AttnRes alters the preferred\ndepth–width–attention trade-off, and in particular, given its potential strength on the depth dimension, whether it favors\ndeeper models compared to conventional Transformer design heuristics. To isolate structural factors directly coupled\nto depth, we fix the per-expert MLP expansion ratio based on internal empirical observations ( dff/dmodel≈0.45 ).\nWe further fix total training compute (FLOPs ≈6.5×1019) and active parameters ( ≈2.3×108), ensuring that any\nperformance variation arises purely from architectural reallocation rather than overall capacity differences. Under\nthis constrained budget, we enumerate 25 configurations on a 5×5 grid over dmodel/Lb∈ {15,30,45,60,75} and\nH/L b∈ {0.3,0.4,0.5,0.6,0.7} , where Lb=L/2 is the number of Transformer blocks and Hthe number of attention\nheads. The results are shown in Fig. 7.\nBoth heatmaps exhibit a shared pattern: loss decreases with growing dmodel/Lband shrinking H/L b, and both methods\nreach their optima at H/L b≈0.3 . Despite this shared trend, AttnRes achieves a lower loss than the baseline in each of\nthe 25 configurations, by 0.019 –0.063 . The most apparent difference lies in the location of the optimum: the baseline\nachieves its lowest loss at dmodel/Lb≈60 (1.847 ), whereas AttnRes shifts it to dmodel/Lb≈45 (1.802 ).

Each heatmap shows how the lth attention or MLP layer (rows) allocates its attention over previous sources\n(columns), with pre-attention and pre-MLP layers shown separately.

Test-Time Training (TTT) [46] formalizes the sequence side of this analogy (cf. Fast\nWeight Programmers [43, 32]), casting each recurrent step as gradient descent on a self-supervised loss:\nWt=W t−1−η∇ℓ(W t−1;xt),(9)\nwhere a slow network parameterizes ℓand the state Wis updated once per token. When fis linear, this reduces to\nvanilla linear attention St=St−1+ktv⊤\nt. The standard residual exhibits the same additive form along depth, with hl\nserving as the state and each layerf lacting as one “gradient step.”\nAs noted by [4], this duality extends to richer variants (Table 5). Data-dependent gates on the sequence side [47, 63]\ncorrespond to Highway networks [45] on the depth side; the delta rule [42, 62, 69] corresponds to DDL [67]; and\nMRLA [10] mirrors GLA’s [63] gated linear attention. These methods all refine the recurrent update while remaining\nwithin the recurrence paradigm. AttnRes goes a step further and replaces depth-wise recurrence with direct cross-layer\nattention, just as Transformers replaced temporal recurrence with self-attention. Since the number of layers in current\narchitectures remains well within the practical regime of softmax attention, we adopt vanilla depth-wise attention.\nIncorporating more expressive yet memory-efficient (e.g. linear-complexity) alternatives is a natural direction for future\nwork.\n6.2 Residual Connections as Structured Matrices\nThe residual variants discussed above can all be viewed as weighted aggregations over previous layer outputs. We\nformalize this with adepth mixing matrix M∈RL×L, where Mi→lis the weight that layer lassigns to the output of\nlayer i. The variants differ in how these weights arise (fixed, learned, or input-dependent) and whether Mis constrained\nto low rank or allowed to be dense. The semiseparable rank ofM[8] offers a unified lens for comparing them.\nConcretely, the input to layer lishl=Pl−1\ni=0Mi→lvi, where v0=h 1(embedding) and vi=fi(hi)fori≥1 .

The effective\nrank of Mtherefore lies between NandN+S (where Sis the block size), interpolating between standard residual\n(N=1) and Full AttnRes (N=L).\nPracticality.The structured-matrix perspective serves two purposes. First, it enables analytical insights that are not\napparent from the recurrence form alone. The input-dependent Mof AttnRes, for instance, reveals depth-wise attention\nsinks (§5.4.2), where certain layers consistently attract high weight regardless of input, mirroring the same phenomenon\nin sequence-wise attention [57]. Second, it informs new designs by exposing which properties of the kernel ϕmatter. For\nexample, when ϕdecomposes as ϕ(q,k) =φ(q)⊤φ(k) for some feature map φ[23], depth-wise attention collapses\ninto a recurrence—precisely the structure underlying the MRLA–GLA and DDL–DeltaNet correspondences noted\nabove.\n15" - }, - { - "page": 16, - "content": "Attention ResidualsTECHNICALREPORT\nPrior Residuals as Depth-Wise Linear AttentionThe structured-matrix perspective further relates to the sequence-\ndepth duality by showing that existing residual variants are, in effect, instances oflinearattention over the depth axis.\nFor example, the unrolled (m)HC weight Mi→l=β⊤\niA×\ni+1→lαl(Eq. 10) admits a natural attention interpretation in\nwhich αlplays the role of a query issued by layer l,βiserves as a key summarizing the contribution of layer i, and\nthe cumulative transition A×\ni+1→lacts as a depth-relative positional operator [69] governing the query–key interaction\nacross intervening layers. Notably, themparallel streams correspond to state expansion [40, 29] along the depth axis,\nexpanding the recurrent state from dtod×m and thereby increasing the semiseparable rank of M. [58] show that\nreplacing A×\ni+1→lwith the identity matrix still yields competitive performance, highlighting the role of state expansion.\nThrough this lens, methods like (m)HC thus act as depth-wiselinearattention with matrix-valued states, while AttnRes\nacts as depth-wisesoftmaxattention.\n7 Related Work\nNormalization, Scaling, and Depth Stability.The standard residual update hl+1=h l+fl(hl)[12] presents a\nfundamental tension betweennormalization placementandgradient propagation. PostNorm [52] maintains bounded\nmagnitudes but distorts gradients, as repeated normalization on the residual path compounds into gradient vanishing at\ndepth [60]. PreNorm [34, 60] restores a clean identity path yet introduces unbounded magnitude growth: since ∥hl∥\ngrows as O(L) , each layer’s relative contribution shrinks, compelling deeper layers to produce ever-larger outputs\nand limiting effective depth [27]. Subsequent work reconciles both desiderata via scaled residual paths [54], hybrid\nnormalization [73], amplified skip connections [4], or learned element-wise gates [45] (see Table 5). AttnRes sidesteps\nthis tension by replacing the additive recurrence with selective aggregation over individual earlier-layer outputs, avoiding\nboth the cumulative magnitude growth of PreNorm and the repeated scale contraction of PostNorm.\nMulti-State Recurrence.All single-state methods above condition layer lonly on hl−1, from which individual\nearlier-layer contributions cannot be selectively retrieved. Several methods address this by widening the recurrence\nto multiple parallel streams: Hyper-Connections [72] and its stabilized variant mHC [59] maintain mstreams with\nlearned mixing matrices; DDL [67] maintains a matrix state updated via a delta-rule erase-and-write mechanism;\nSiameseNorm [27] maintains two parameter-shared streams—one PreNorm and one PostNorm—to preserve identity\ngradients and bounded representations. While these methods alleviate information compression, they still condition\non the immediate predecessor’s state; AttnRes is orthogonal, providing selective access to individual earlier-layer\noutputs while remaining compatible with any normalization or gating scheme. We discuss the formal connection to\nHyper-Connections in § 6.2.\nCross-Layer Connectivity.A separate line of work bypasses the single-state bottleneck by giving each layer direct\naccess to individual earlier-layer outputs. The simplest approach uses static weights: DenseNet [17] concatenates all\npreceding feature maps; ELMo [38] computes a softmax -weighted sum of layer representations with learned scalar\nweights; DenseFormer [36] and ANCRe [68] assign learned per-layer scalar coefficients fixed after training. For\ninput-dependent aggregation, MUDDFormer [56] generates position-dependent weights via a small MLP across four\ndecoupled streams; MRLA [10] applies element-wise sigmoid gating over all previous layers, though its separable\nquery–key product is closer to linear attention than softmax -based retrieval. Other methods trade full cross-layer access\nfor more targeted designs: Value Residual Learning [71] accesses only a single earlier layer; LAuReL [30] augments\nthe residual with low-rank projections over the previous kactivations; Dreamer [24] combines sequence attention with\ndepth attention and sparse experts. AttnRes combines softmax -normalized, input-dependent weights with selective\naccess to all preceding layers through a single d-dimensional pseudo-query per layer, and introduces a block structure\nreducing cost from O(L2)toO(LN) . Cache-based pipeline communication and a two-phase computation strategy\n(§ 4) make Block AttnRes practical at scale with negligible overhead.\nConclusion\nInspired by the duality between sequence and depth, we introduce AttnRes, which replaces fixed, uniform residual\naccumulation with learned, input-dependent depth-wise attention. We validate the method through ablation studies and\nscaling law experiments, showing that its gains persist across scales. Because Full AttnRes must access all preceding\nlayer outputs at every layer, the memory footprint of cross-layer aggregation grows as O(Ld) , which is prohibitive\nfor large-scale models on current hardware. We therefore introduce Block AttnRes, which partitions layers into N\nblocks and attends over block-level representations. Empirically, using about 8 blocks recovers most of the gains of Full\nAttnRes, while finer-grained blocking remains a promising direction as future hardware constraints relax. Together with\ncross-stage caching and a two-phase computation strategy, Block AttnRes is practical at scale, incurring only marginal\ntraining overhead and minimal inference overhead.\n16" - }, - { - "page": 17, - "content": "Attention ResidualsTECHNICALREPORT\nReferences\n[1] Jacob Austin et al.Program Synthesis with Large Language Models. 2021. arXiv: 2108.07732 [cs.PL] .URL:\nhttps://arxiv.org/abs/2108.07732.\n[2] Thomas Bachlechner et al.ReZero is All You Need: Fast Convergence at Large Depth. 2020. arXiv: 2003.04887\n[cs.LG].URL:https://arxiv.org/abs/2003.04887.\n[3] Dzmitry Bahdanau, Kyunghyun Cho, and Yoshua Bengio.Neural Machine Translation by Jointly Learning to\nAlign and Translate. 2016. arXiv:1409.0473 [cs.CL].URL:https://arxiv.org/abs/1409.0473.\n[4] Chen Chen and Lai Wei.Post-LayerNorm Is Back: Stable, ExpressivE, and Deep. 2026. arXiv: 2601.19895\n[cs.LG].URL:https://arxiv.org/abs/2601.19895.\n[5] Mark Chen et al.Evaluating Large Language Models Trained on Code. 2021. arXiv: 2107.03374 [cs.LG] .\nURL:https://arxiv.org/abs/2107.03374.\n[6] Peter Clark et al. “Think you have Solved Question Answering?

As noted in §4.2, however, the pseudo-query wlis a learned parameter independent of both the\ninput and the hidden state. We can therefore batch inter-block accesses across layers in a two-phase schedule, bringing\ntotal I/O well below the naïve bound.\nNote that the block partition introduced below is purely an inference scheduling device. Unlike Block AttnRes, it leaves\nthe model architecture unchanged and does not replace per-layer sources with block summaries; it simply makes the\namortization argument concrete.\nSetupLet the model have Llayers and hidden dimension d, partitioned into Ncontiguous blocks of size S=L/N .\nInference proceeds one block at a time: Phase 1 jointly computes inter-block attention for all Slayers in the block\nagainst all preceding blocks, and Phase 2 walks through intra-block dependencies sequentially.\nPhase 1: Batched Inter-block Attention\nConsider block nwith its Slayers. The queries {wl}l∈Bnare all known before execution begins, so the (n−1)S\npreceding key–value pairs need only be read once from HBM and reused across all Squeries. The read cost for block n\nis therefore\nRead(n)\ninter= 2(n−1)Sd,(11)\nwhere the factor of2accounts for both keys and values. Summing over allNblocks and usingSN=L:\nRead inter=NX\nn=12(n−1)Sd= 2Sd·N(N−1)\n2=dL(N−1).(12)\nPhase 1 also writes oned-dimensional output per layer, givingWrite(n)\ninter=Sdper block and\nWrite inter=Ld(13)\nin total.\nPhase 2: Sequential Intra-block Attention\nPhase 1 covers all sources before the current block. Within the block, however, each layer depends on those before it,\nso these must be handled in order. Layer t(1≤t≤S ) reads t−1 intra-block key–value pairs at a cost of 2(t−1)d .\nSumming over one block:\nRead(n)\nintra=SX\nt=12(t−1)d=S(S−1)d.(14)\nPhase 2 also writes one output per layer, soWrite(n)\nintra=Sd.\nTotal Amortized I/O per Layer\nSumming both phases over allNblocks:\nRead total=dL(N−1) +N·S(S−1)d,Write total= 2Ld.(15)\nDividing byLand usingSN=L:\nRead per layer= (N−1)d+ (S−1)d= (S+N−2)d,Write per layer= 2d,(16)\nTotal I/O per layer= (S+N)d. (17)\nBatching inter-block reads thus brings per-layer I/O from O(L) down to O(S+N) . The schedule follows the same\ntwo-phase split as Block AttnRes: inter-block attention accounts for the bulk of the traffic, while sequential computation\nstays local within each block.\n21" - } - ] -} \ No newline at end of file diff --git a/examples/workspace/_meta.json b/examples/workspace/_meta.json deleted file mode 100644 index daf212c70..000000000 --- a/examples/workspace/_meta.json +++ /dev/null @@ -1,9 +0,0 @@ -{ -

The guard runs after doc_ids normalization and before the completion request; query_stream runs it via asyncio.to_thread. Folders unavailable on the plan -> guard skips, as with the sibling ops. Also rename the streaming QueryEvent types answer_delta/answer_done -> text_delta/text_done: text_done fires once per assistant text message, which is honest for the local agent loop's multi-message stream (the last one before the stream ends carries the final answer). Corrects the cloud backend's now-inaccurate "single terminal contract" comment. reasoning stays reserved for future model-reasoning tokens. QueryEvent is unreleased API (0.3.0.dev1), so the rename is not a breaking change. --- README.md | 4 ++-- examples/cloud_demo.py | 4 ++-- examples/demo_query_modes.py | 2 +- examples/local_demo.py | 4 ++-- pageindex/agent.py | 6 +++--- pageindex/backend/cloud.py | 16 +++++++++++---- pageindex/events.py | 2 +- tests/test_cloud_backend.py | 38 +++++++++++++++++++++++++++++++++--- tests/test_events.py | 6 +++--- 9 files changed, 61 insertions(+), 21 deletions(-) diff --git a/README.md b/README.md index 643d99082..adb7fafb2 100644 --- a/README.md +++ b/README.md @@ -179,7 +179,7 @@ import asyncio async def main(): async for ev in col.query("Explain multi-head attention", doc_ids=doc_id, stream=True): - if ev.type == "answer_delta": + if ev.type == "text_delta": print(ev.data, end="", flush=True) elif ev.type == "tool_call": print(f"\n[tool] {ev.data['name']}") @@ -187,7 +187,7 @@ async def main(): asyncio.run(main()) ``` -`ev.type` is one of: `tool_call`, `tool_result`, `answer_delta`, `answer_done`. +`ev.type` is one of: `tool_call`, `tool_result`, `text_delta`, `text_done`.

Adjust it: - process_toc_no_page_numbers: a count-mismatched or reordered/renamed LLM response no longer raises ValueError (which aborted the entire index at the uncaught top-level path and defeated the return_exceptions degradation the rest of the pipeline uses). Skip the untrusted chunk and continue; the accuracy check falls back to another mode when too little gets filled. - _secure_doc_text: drop the keyword blocklist that replaced phrases like "act as"/"disregard" with [REDACTED]. Those occur in legitimate titles and prose, so redaction corrupted document content. Keep the <user_document> framing + _SYSTEM_HARDENING system instruction as the injection defense. - _validate_chunk_physical_indices: tolerate non-list input (extract_json returns {} on parse failure and may return a JSON object) instead of crashing while iterating a dict. - Remove _validate_physical_indices / _parse_physical_index: range validation is already done by validate_and_truncate_physical_indices in meta_processor and marker->int by convert_physical_index_to_int; the helpers duplicated both. Tests updated to assert the skip-not-raise behavior and lock in no-redaction and non-list tolerance. 314 passed, 2 skipped. --- pageindex/index/page_index.py | 86 ++++++++++------------------------- tests/test_page_index.py | 60 ++++++++++++++++++++---- 2 files changed, 77 insertions(+), 69 deletions(-) diff --git a/pageindex/index/page_index.py b/pageindex/index/page_index.py index d6468d22b..a0ea4fff1 100644 --- a/pageindex/index/page_index.py +++ b/pageindex/index/page_index.py @@ -10,23 +10,6 @@ ######################### Hardening for prompt injection patterns #################################################### -_INJECTION_PATTERNS = re.compile( - r"(?i)(" - r"system\s+override|" - r"ignore\s+(all\s+)?(previous|prior|above)\s+instructions?|" - r"forget\s+(all\s+)?(previous|prior|above)\s+instructions?|" - r"you\s+are\s+now|act\s+as|new\s+instructions?|" - r"do\s+not\s+follow|override\s+(the\s+)?(system|previous|prior)|" - r"disregard|jailbreak|ALL\s+sections\s+MUST" - r")" -) - - -def _sanitize_doc_text(text: str) -> str: - """Redact known prompt-injection keywords from PDF-extracted text.""" - return _INJECTION_PATTERNS.sub("[REDACTED]", text) - - def _wrap_doc_text(text: str) -> str: """Wrap untrusted document text in delimiter tags so the LLM treats it as data.""" text = re.sub(r"(?i)<(?=\s*/?\s*user_document\b)", "<", text) @@ -50,38 +33,17 @@ def _wrap_doc_text(text: str) -> str: def _secure_doc_text(text: str) -> str: - """Sanitize + delimiter-frame a PDF text block before LLM injection.""" - return _wrap_doc_text(_sanitize_doc_text(text)) - - -_PHYSICAL_INDEX_MARKER_RE = re.compile(r"^<physical_index_(\d+)>$") - + """Delimiter-frame a document text block so the LLM treats it as data. -def _parse_physical_index(raw): - if raw is None: - return None - marker_match = _PHYSICAL_INDEX_MARKER_RE.match(str(raw).strip()) - if marker_match: - return int(marker_match.group(1)) - try: - return int(raw) - except (TypeError, ValueError): - return None + Deliberately no keyword redaction: phrases like "act as" / "disregard" + also appear in legitimate titles and prose, and blanking them corrupts the + content this reasoning-based index relies on.

Both now resolve explicit args > YAML > IndexConfig field defaults via IndexConfig.from_yaml, matching the CLI. The new SDK keeps its pure-code config path. import pageindex also lost the utils / page_index_md submodule attributes (pageindex.utils.print_tree raised AttributeError). A module __getattr__ now imports the shims lazily, so plain imports stay free of deprecation warnings while first use of a legacy attribute binds the module and warns. Also trims non-essential comments from the BASE_URL fix.
