chore(deps): bump @earendil-works/pi-tui from 0.75.5 to 0.84.0

[dependabot]

Bumps @earendil-works/pi-tui from 0.75.5 to 0.84.0.

Release notes

Sourced from @​earendil-works/pi-tui's releases.

v0.84.0

New Features

• Fullscreen TUI mode — Switch between regular and fullscreen modes at runtime, with a sticky editor and footer, independently scrollable transcript, and draggable scrollbars. See UI & Display.
• Mermaid and LaTeX rendering — Render Mermaid diagrams and terminal-friendly Unicode math in interactive transcripts. See Markdown settings and TUI Markdown.
• Per-directory context overrides — Use AGENTS.override.md to replace context files for a specific directory. See Context Files.
• Advanced custom model sampling — Configure arbitrary OpenAI-compatible samplingParams and opt-in vLLM thinking_token_budget values. See Sampling Parameters.
• Baseten provider — Use built-in Baseten authentication and model support. See API Keys.

Breaking Changes

• Renamed the inherited pi-ai ModelsStreamTransforms interface to ModelsRequestTransforms because its header transformation now applies to all authenticated provider requests.

• Changed JSON and RPC message_update events to emit only assistantMessageEvent deltas, removing the cumulative message and assistantMessageEvent.partial fields that caused quadratic output growth. Clients that need partial messages must assemble deltas between message_start and message_end; the latter remains authoritative (#7290).

• ModelRegistry.getApiKeyAndHeaders() now returns ProviderHeaders with string | null values and preserves null header-deletion markers. Extensions that inspect returned headers must handle null; extensions forwarding them to pi-ai streams should pass them through unchanged. This prevents placeholder OpenAI credentials from being sent through Cloudflare AI Gateway (#7030).

• Changed ModelRegistry.refresh() to accept ModelsRefreshOptions and return ModelsRefreshResult instead of discarding cancellation and provider errors.

• Changed ModelRuntime.setRuntimeApiKey() to accept auth cancellation options rather than catalog refresh options. Call refresh({ providers: [providerId], signal }) separately when remote freshness is required.

• Required config-form extension OAuth refreshToken(credentials, signal) callbacks to accept and honor a concrete abort signal.

• Replaced dynamic provider refresh context store access with the read-only context.stored snapshot and generation-checked context.publish() transaction.

  Providers built with createProvider({ fetchModels }): no catalog-publication migration is required. Before and after, return the fetched models and register the resulting provider; createProvider() owns restoration, persistence, and in-memory publication.

  // Before
  const beforeProvider = createProvider({
    // ...
    fetchModels: async ({ signal }) => {
      const response = await fetch(catalogUrl, { signal });
      return parseModels(await response.json());
    },
  });
  pi.registerProvider(beforeProvider);
  // After: unchanged
  const afterProvider = createProvider({
  // ...
  fetchModels: async ({ signal }) => {
  const response = await fetch(catalogUrl, { signal });
  return parseModels(await response.json());
  },
  });
  pi.registerProvider(afterProvider);

  Handwritten native Provider.refreshModels(): replace direct store access and pre-publication mutation with generation-guarded publications.

  // Before
  refreshModels: async (context) => {
    const stored = await context.store.read();
    if (stored) currentModels = stored.models;

Changelog

Sourced from @​earendil-works/pi-tui's changelog.

[0.84.0] - 2026-08-06

Added

• Added terminal-friendly Unicode rendering for LaTeX expressions in Markdown, including inline and display math, fractions, scripts, common symbols, aligned equations, cases, and matrices.
• Added the shared TuiMode type and mode discriminants to the main-screen and alternate-screen TUI renderers.
• Added TUI lifecycle and render-state handoff APIs for replacing renderers without replaying main-screen content.
• Exported the bundled Marked parser and token types.
• Added width-aware source transforms to the Markdown component.
• Added interface-compatible main-screen and alternate-screen TUI renderers with application-owned scrolling (#7304).
• Added alternate-screen VStack, HStack, and nested ScrollView layouts with constrained sizing, sticky regions, and pointer-targeted scrolling.
• Added edge auto-scrolling for alternate-screen drag selection across off-screen scroll-view content.
• Added proportional scrollbars with mouse dragging, Home/End document navigation, transient auto mode, and an always mode that reserves the rightmost column; scrollbar modes can be changed at runtime.
• Added page scrolling and OSC 133 semantic prompt navigation to the alternate-screen viewport.
• Added configurable previous/next prompt history actions for navigation independent of vertical cursor movement.
• Added stacked transient notifications to the alternate-screen renderer (#7361).

Changed

• Reduced the default alternate-screen mouse wheel step from three lines to one for finer scrolling.

Fixed

• Fixed Windows Shift+Enter detection by extending the native Win32 helper to report modifier key state.
• Fixed the npm package omitting the source and build script needed to rebuild the Windows native addon.
• Fixed the npm package omitting the source and build script needed to rebuild the Darwin native addon.
• Fixed Windows console truecolor detection when Windows Terminal does not provide WT_SESSION to child shells.
• Fixed terminal width accounting for Indic conjunct grapheme clusters (#6987 by @​petrroll).
• Fixed phantom alternate-screen text selection from unmatched mouse events when changing terminal pane focus.
• Fixed spaces in searchable settings queries changing the selected value instead of filtering multi-word labels.
• Fixed alternate-screen Kitty images crossing vertical layout clip boundaries and overlapping sticky regions while scrolling.
• Fixed alternate-screen redraws retransmitting Kitty image data when placements move or recently offscreen images return, dropping adjacent row content when reusing placements, rendering fixed-basis scroll content twice per frame, and scanning clipped transcript rows while painting.
• Fixed fullscreen transcript navigation leaving no editor-accessible Home, End, PageUp, or PageDown variants by adding Ctrl-modified editor bindings (#7574).
• Fixed keyboard input rendering latency on Windows by letting input preempt the throttled render timer.
• Fixed nested stack layouts ignoring child minimum sizes.
• Fixed batched terminal color-scheme reports being parsed as one malformed response (#7550).
• Fixed terminal progress clearing to emit the complete OSC 9;4 sequence (#7581).
• Fixed iTerm2 image payloads omitting the size metadata required by the xterm.js image addon (#7612).
• Fixed width truncation leaving OSC 8 hyperlinks unterminated (#7657 by @​xXJSONDeruloXx).

[0.83.0] - 2026-07-29

Fixed

• Fixed long image fallback paths overflowing narrow terminals, shortened home-directory paths, and made absolute paths clickable when terminal hyperlinks are available (#7262).
