v0.2.0

Minor Changes

• f2846df: Standalone query engine, concurrent tool scheduler, and Apache-2.0 licensing.

  This release replaces the React useChat-based chat harness with a dedicated,
  framework-agnostic query engine, adds a concurrency-aware tool scheduler, and
  hardens the interactive terminal experience. The project is now formally
  licensed under Apache-2.0.

  Added

  • Standalone query engine. A new engine loop drives a turn end-to-end,
    independent of the React render tree (lib/engine/). It owns engine event and
    params types, a transcript-repair pass that resolves dangling/unresolved tool
    calls, and tool-gating decisions backed by a loop guard to prevent runaway
    tool cycles.
  • useQueryEngine hook. A thin React hook that drives the engine loop and
    replaces the previous useChat harness entirely.
  • Concurrency-aware tool scheduler. Engine-owned scheduling policy runs tool
    rounds with bounded concurrency. Introduces an engine ToolHost contract and a
    hook adapter so the engine can execute tools without depending on the UI layer.
  • Cross-session project memory. Durable, non-obvious facts are extracted
    automatically after completed turns into a per-project store
    (~/.knightcode/projects/<cwd>/memory/) with a MEMORY.md recall index.
    Relevant memories are recalled into the system prompt, a consolidation
    ("dream") pass merges and prunes the store, and a Memory tool lets the model
    review, correct, or forget entries.
  • Per-row tool spinners. Concurrently running tools each get their own inline
    spinner instead of a single shared indicator.
  • @-mention path expansion. Paths referenced with @ in a prompt are
    expanded into the model's context at submit time.
  • PostToolUse systemMessage surfacing. Messages emitted by PostToolUse
    hooks are now surfaced to callers.
  • Apache-2.0 license. Added root LICENSE and NOTICE files and license
    fields in the workspace and CLI package.json.

  Changed

  • Extracted compactHistory out of the old use-chat module and moved chat
    message types into lib/engine/messages.
  • Exposed a hook-free executeRegisteredTool for engine use.
  • Unified all interactive prompts onto a single shared permission panel.
  • Dropped the unused sessionId from QueryParams.
  • Pointed repository URLs at the KnightCodeAI org and scoped the publish
    workflow to publishable paths.

  Fixed

  • Quit behaviour: /exit is now the only way to quit; Ctrl+C never exits.
  • Permissions: every confirm-gated tool now shows a permission prompt, and
    every awaited tool decision is guaranteed a resolvable prompt; scoped the
    always-allow sweep correctly.
  • Markdown rendering: convert <br> to real line breaks in prose, expand
    <br> table cells into continuation rows, and stop rendering literal <br>
    tags.
  • Interrupts: render the interrupted marker after the partial response, with
    a plain interrupted notice (no emoji or completion verb); render interrupted
    aborts and surface queued mid-turn submits.
  • History integrity: stop schema-validating history and instead quarantine
    invalid tool calls.
  • State sync: synchronize message-ref writes, guard submit re-entry, persist
    the final turn snapshot, queue mid-turn submits, clear finished todos, and only
    clear the compacting state when it was actually set.
  • Hardened file reads, question cancellation, and transcript text handling, plus
    a sweep of code-review findings across the engine and UI.
