From 6bf7b9601d8ab43da544084f029ad87a375502df Mon Sep 17 00:00:00 2001 From: oyi77 Date: Tue, 28 Apr 2026 16:58:17 +0700 Subject: [PATCH 1/2] =?UTF-8?q?feat(compression):=20Phase=203=20=E2=80=94?= =?UTF-8?q?=20aggressive=20mode=20with=20summarization,=20tool=20compressi?= =?UTF-8?q?on,=20and=20progressive=20aging?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the aggressive compression pipeline (issue #1588) with three core stages: tool-result compression, progressive aging, and rule-based summarization. Includes downgrade chain to caveman/lite when savings are insufficient. Core modules: - summarizer.ts: RuleBasedSummarizer with intent/file/error/decision extraction, code fence trimming, skip-already-compressed guard - toolResultCompressor.ts: 5 auto-detected strategies (fileContent, grepSearch, shellOutput, json, errorMessage) with toggle support - progressiveAging.ts: 4-tier degradation (verbatim→light→moderate→ fullSummary) with [COMPRESSED:aging:] markers - aggressive.ts: Orchestrator with 3-step pipeline and downgrade chain (aggressive→caveman→lite→as-is) Integration: - strategySelector.ts: applyCompression() now dispatches mode='aggressive' - compression.ts: aggressiveConfig CRUD with deep merge of nested objects - API route: Zod schema for aggressiveConfig thresholds/strategies - CompressionSettingsTab: aggressive mode card, thresholds, toggles, i18n - Migration 031: SELECT 1 no-op (config stored as kv key) Tests: 109 across 8 files (types, summarizer, toolResultCompressor, progressiveAging, aggressive, integration, golden eval, caveman regression) All pass. Typecheck clean. Lint clean (0 errors).
