From 61472a6ff0b6d8514af96fd3cd39ea59fbad3699 Mon Sep 17 00:00:00 2001 From: 0neStep <146049978+AperturePlus@users.noreply.github.com> Date: Thu, 26 Feb 2026 00:03:24 +0800 Subject: [PATCH 1/6] fix(tokenizer): support configurable chunk token strategies Why: - Indexing against Ollama WordPiece-based embedding models can exceed model context limits because chunk sizing used only cl100k_base token counts. - Ollama error payloads using "input length exceeds the context length" were not consistently classified as token-limit failures. What: - Added tokenizer strategies (tiktoken, character, simple) and strategy-based default tokenizer factory. - Added ACI_TOKENIZER config/env support and wired tokenizer selection into service initialization so chunking and summary generation share the chosen tokenizer. - Expanded token-limit error detection to include context-length style 400 responses. - Updated unit/property tests for tokenizer strategy selection, offline-safe tokenizer tests, config strategy generation, and token-limit message coverage.

The latest MCP changes also expanded the context contract and exposed a flaky Hypothesis deadline in file scanner tests. What: apply runtime path mappings before native absolute-path fallback, add runtime path resolution coverage for Windows and POSIX host paths, update MCP/qdrant/property tests to match the new contract, and disable the flaky deadline on the ignore-pattern property test.
