Changelog

[0.3.2] - 2026-09-16

Added

  • Statusline Retrieval Indicator & Extension Row Integration: Relocated the retrieval profile tag from Line 1 to Line 2 (extension statusline via ctx.ui.setStatus("retrieval", ...)) alongside external extensions (such as Ponytail), preserving individual extension ANSI colors.
  • Profile Semantic Glyphs: Added distinct visual tier glyphs: 🌿 retrieval:bm25 (AST lexical), ◈ retrieval:hybrid-256d (Matryoshka hybrid), and 🧠 retrieval:dense-768d (Full semantic).
  • Live Embedding Throughput & Stream Arrow Status: Added real-time chunk processing throughput (chunk/s) with a static Stream Arrow indicator during workspace indexing (🧠 retrieval:dense-768d ⇢ 45% (22/48 • 14.2 chunk/s)).
  • Automatic Kernel Guidance Injection: Bundled AGENT_KERNEL_SYS_PROMPT.md is injected through Pi's before_agent_start lifecycle hook, enabled by default and configurable with [instructions] enabled = false.
  • Benchmark Comparison Chart: Added the latest aggregate harness comparison graphic at static/benchmark-comparison.png for display in the project README.
  • Six-Harness Cross-Agent Benchmark: Integrated comprehensive multi-harness comparison runner supporting Pi Kernel, Pi Vanilla, Claude Code, Codex CLI, OMP, and OpenCode across 8 real-world tasks.
  • Passive Shield Architecture: Gated exploratory tools (ast_search, get_repo_map, lsp) behind enable_tools: false / PI_ENABLE_ALL_RETRIEVAL_TOOLS=1, keeping the active tool interface lean (read, edit, write, bash, and compact code_search) to eliminate per-turn schema overhead and tool distraction loops.
  • Deterministic Delimiter Auto-Healing: Added patch-scoped lexical delimiter balancing and Tree-sitter AST repair (MISSING node detection) to automatically recover truncated closing braces/brackets (}), };, ]}) pre-write.
  • Line-Hinted Range Disambiguation & Multi-Block Line Deltas: Added optional line_hint, start_line, and end_line parameters (supporting both camelCase and snake_case) to edit with sequential delta tracking to disambiguate identical search blocks without line-hash bloat.
  • Capped Plain-Text Reads: Enforced 50KB / 2,000-line caps on broad reads with continuation hints (offset) and oversized line detection, recording precise exposure ranges in EpistemicGuard.
  • Model Property Aliasing & Epistemic Confirmation: Supported model convention drift across parameter names (search/replace, old/new, old_text/new_text) and emitted concise positive confirmation strings (Successfully applied edit to <file>.) to prevent paranoid agent verification loops.

Changed

  • Included AGENT_KERNEL_SYS_PROMPT.md in the published package so automatic guidance works after installation.
  • Added lifecycle coverage for guidance injection, duplicate prevention, and the disabled configuration path.
  • Tool Description Optimization: Completely redesigned tool descriptions for read and edit to explicitly declare clean plain-text defaults and precision parameter expectations, dropping 10k+ prompt inflation tokens on real benchmarks.
  • Diagnostic Benchmark: Cut token consumption by 50.6% (762k vs 1.54M total turn tokens) and reduced tool calls by 24.8% (112 vs 149) compared to unguided Pi Vanilla on the 8-task Luna High diagnostic suite.
  • Historical Benchmark: In the initial v0.3.1-to-v0.4.0 Passive Shield evaluation, token consumption dropped from 1,214,112 tokens down to 465,139 tokens (-61.7%) across 8 real-world repositories.
  • Persistent Vector Profiles: Preserved dimension-specific binary caches (vectors-256d.bin, vectors-768d.bin) on disk across profile switches, preventing cache loss when toggling to BM25.
  • On-Demand Embedder Loading: Removed premature model preloading on startup; weights load on-demand only when unindexed chunks are detected.

Fixed

  • Startup Background Indexing Visibility: Fixed a bug where workspace indexing on session_start ran silently in the background without updating the UI statusline on cold or unindexed workspaces.
  • Companion Symbol Token Inflation: Deduplicated companion symbols and clamped surrounding context lines during targeted symbol reads to eliminate token bloat.

Removed

  • Removed the obsolete AGENT_KERNEL_PROPMPTS.md prompt document.
