deps(deps): bump @earendil-works/pi-agent-core from 0.82.1 to 0.84.1

[dependabot]

Bumps @earendil-works/pi-agent-core from 0.82.1 to 0.84.1.

Release notes

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

v0.84.1

New Features

• Qwen Token Plan Individual — Use the built-in provider for models documented for Individual subscriptions. See API Keys.
• Authentication readiness checks — Use pi auth check to verify provider or model credentials, optionally emitting the resolved credential.
• Improved fullscreen interaction — Select words and paragraphs with multiple clicks and configure half-page transcript scrolling. See TUI Fullscreen Viewport.
• Terminating blocked tool calls — Extension tool_call handlers can stop all-terminating batches without another model call. See Tool Events.

Added

• Added Qwen Token Plan Individual as a built-in provider with its documented subscription model catalog and the shared international QWEN_TOKEN_PLAN_API_KEY. See API Keys (#7659 by @​arasovic).
• Added pi auth check provider/model auth preflight with optional credential output (#7152).
• Added terminate support to blocked extension tool_call events so all-terminating batches can skip the automatic follow-up model call. See Tool Events (#7715 by @​muyiyr).
• Added inherited double-click word and whitespace selection, granularity-aware drag selection, and triple-click paragraph selection in fullscreen mode (#7725, #7733 by @​volsa).
• Added inherited unbound half-page transcript scrolling actions for fullscreen mode. See TUI Fullscreen Viewport (#7735).

Changed

• Softened the bash tool's PI_* environment guideline in an attempt to reduce unnecessary inspection commands (#7128).
• Reduced worst-case automatic terminal theme detection delay from 200 ms to 100 ms by probing color-scheme and background support concurrently.

Fixed

• Fixed Bun standalone binaries crashing on startup when the cwd contains a bunfig.toml with preload by compiling with --no-compile-autoload-bunfig (#7685 by @​geril07).
• Fixed extension TUI method wrappers recursing indefinitely when delegating to the original method (#7731).
• Fixed right-click not pasting clipboard text in fullscreen mode on Windows.
• Fixed inherited Agent.reset() clearing transcript and runtime state during active runs; it now rejects until the agent is idle (#7717 by @​wesleyzhangwq).
• Fixed inherited LaTeX relation, multiplication, and named-operator spacing, and matrix composition with stacked fractions, operator limits, and adjacent matrices.
• Reduced inherited fullscreen mouse event volume under tmux, Zellij, and GNU Screen by using button-motion tracking instead of all-motion tracking.

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.

Changelog

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

[0.84.1] - 2026-08-07

Added

• Added BeforeToolCallResult.terminate so blocked tool calls can participate in the existing batch early-termination rule (#7715 by @​muyiyr).

Fixed

• Fixed Agent.reset() clearing transcript and runtime state during active runs; it now rejects until the agent is idle (#7717 by @​wesleyzhangwq).

[0.84.0] - 2026-08-06

Breaking Changes

• Replaced the legacy harness session model with the v4 lane-based Session, SessionStorage, and SessionRepo APIs, including durable operation records, global facts, shared sequence numbers, and tree-scoped lane views.
• Promoted the v2 session and AgentHarness API from the experimental entrypoint to the default package export and removed the experimental subpaths.
• Removed the legacy JSONL and in-memory repository APIs. Use the v4 JsonlSessionRepo or InMemorySessionRepo, both implementing the new SessionRepo contract.
• Added the required FileSystem.renameFile() operation to harness execution environments for atomic JSONL publication; custom file-system implementations must provide same-filesystem replacement semantics (#7707 by @​davidbrai).

Added

• Added typed AI-request and harness telemetry schemas, their combined schema tuple, callback helpers, and a generated schema reference.
• Added bounded Session.findEntriesOnBranch() and findEntryOnBranch() queries with explicit traversal, filtering, ordering, and limit options.
• Added a compile-complete AgentHarness v2 scaffold; unfinished operation paths reject with HarnessNotImplemented while durable execution is implemented.
• Added JsonlSessionRepo, a v4 append-only JSONL session repository with metadata validation and shared storage semantics (#7611 by @​davidbrai).
• Added indexed Session.findOpenOperations() recovery queries and RecordQuery.operationKind filtering (#7646).
• Added AgentOptions.shouldStopAfterTurn for gracefully stopping after a completed turn before queued messages or another model call are processed. See Agent Options (#7367 by @​acmerfight).
• Added proxy forwarding for arbitrary OpenAI-compatible samplingParams (#7568 by @​mrexodia).

Fixed

• Fixed Windows path handling for NodeExecutionEnv file basenames, recursive skill loading, and prompt template names.
• Fixed JsonlSessionRepo enforcing session IDs globally across working directories; IDs are now unique within each working directory.
• Fixed JSONL session forks and torn-tail repairs to publish atomically, avoiding partially written or corrupted sessions after interrupted writes (#7707 by @​davidbrai).
