Bumps undici to 8.9.0 and updates ancestor dependency @earendil-works/pi-coding-agent. These dependencies need to be updated together.

Updates undici from 8.5.0 to 8.9.0

Release notes

Sourced from undici's releases.

v8.9.0

⚠️ Security fixes

High severity

• GHSA-4cwx-7wf7-3272: malformed qualified private Cache-Control directives could cause cross-user information disclosure in shared caches or a parse-time crash. The cache parser now treats empty qualified directives conservatively and safely handles mixed qualified and unqualified directives. Fixed by 4fe5bc5f with regression coverage in 9f09b49a.

Medium severity

• GHSA-m8rv-5g2x-5cg5: a malicious type property on a duck-typed blob-like HTTP/1.1 request body could inject CRLF sequences into the generated content-type header. Undici now coerces and validates the value before adding it to the request. Fixed by 7d3cf924.
• GHSA-jr45-8vmc-qm54: optional whitespace around = in qualified no-cache and private directives could bypass shared-cache restrictions and disclose authenticated data across users. Cache-Control parsing now normalizes these forms and applies conservative cache decisions. Fixed by c601fff1.
• GHSA-8xcm-r25x-g524: the retry interceptor could expose a stale Content-Length after resuming a partial response, potentially causing downstream response desynchronization, hangs, or corruption. Undici now rejects partial responses whose Content-Length is inconsistent with Content-Range. Fixed by e11a68ed, with corrected fixtures in 2b3f7493.
• GHSA-v3r7-h72x-cjcm: unsanitized domain and unparsed values passed to setCookie() could inject cookie attributes. Undici now validates cookie domains, paths, and unparsed attributes more strictly. Fixed by 10d93fc3.

Additional hardening

Undici now validates non-string header values after coercion, including array elements, preventing crafted toString() or Symbol.toPrimitive implementations from introducing CRLF sequences. This defense-in-depth change was made in 354a151f.

Updates @earendil-works/pi-coding-agent from 0.83.0 to 0.84.0

Release notes

Sourced from @​earendil-works/pi-coding-agent'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;

Mira PR Walkthrough

This is a Dependabot dependency bump PR that updates the @earendil-works/pi-coding-agent devDependency from ^0.83.0 to ^0.84.0, which also brings an updated undici (8.5.0 → 8.9.0) as a transitive dependency. The undici update includes several security fixes (cache directive parsing, CRLF injection in blob types, cookie attribute validation, retry interceptor partial response handling). The pi-coding-agent bump is a minor version upgrade per its semver.

Confidence: 5/5   ◉◉◉◉◉   Safe to merge

• Single-line version bump in a devDependency with a minor semver upgrade; Dependabot's CI checks should catch any breakage, and undici's security fixes are purely beneficial.
