chore(deps): bump @earendil-works/pi-agent-core from 0.79.6 to 0.81.1 in /backend

[dependabot]

Bumps @earendil-works/pi-agent-core from 0.79.6 to 0.81.1.

Release notes

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

v0.81.1

New Features

• Verifiable release source archives — GitHub releases now include deterministic, checksummed source archives with instructions for rebuilding standalone binaries. See Building standalone binaries from release source.
• Resilient compaction and branch summaries — Transient provider failures now follow the configured retry policy, with retry lifecycle events available to interactive, JSON, RPC, and SDK consumers. See Compaction & Branch Summarization and RPC retry events.

Added

• Added deterministic, checksummed source archives to GitHub releases with documented standalone binary rebuild instructions (#6913 by @​christianklotz).

Fixed

• Fixed compaction and branch summarization to retry transient provider failures using the configured retry policy, with retry lifecycle events exposed to interactive, JSON, RPC, and SDK consumers (#6901 by @​davidbrai).
• Fixed interactive startup waiting for background model catalog refresh while computing the footer provider count.
• Restored the default stream fallback for extensions using the pre-0.81 agent-core API (#6915).
• Fixed inherited Kimi K3 models from Moonshot AI and Moonshot AI China to use the OpenAI thinking format and expose reasoning effort support.

v0.81.0

New Features

• Local llama.cpp model management — Connect to a llama.cpp router, search and download Hugging Face models, and explicitly load or unload models with live progress. See llama.cpp.
• Full provider extensions — Extensions can register complete pi-ai providers with authentication, model refresh, filtering, and custom streaming. See Register New Provider.
• Qwen Token Plan providers — Use the built-in international and China subscription providers with regional endpoints and API-key authentication. See API Keys.
• Expanded usage accounting — Tool, compaction, and branch-summary usage is persisted and included in session totals. See Compaction & Branch Summarization.

Added

• Added Qwen Token Plan and Qwen Token Plan China to built-in provider setup, default model resolution, and provider documentation (#6858 by @​QuintinShaw).
• Added the get_available_thinking_levels RPC command and RpcClient.getAvailableThinkingLevels() method (#6865 by @​cristinaponcela).
• Exported message and tool execution lifecycle event types from the package root (#6772 by @​davidbrai).
• Added built-in llama.cpp router support with /login connection setup and /llama Hugging Face model search and downloads, explicit loading, unloading, and live progress. See llama.cpp.
• Added extension registration for complete pi-ai providers, including native authentication, model refresh, filtering, and streaming behavior.
• Added usage accounting for tools, compaction, and branch summaries in persisted sessions, footer totals, and session statistics (#6671 by @​davidbrai).

Fixed

• Updated the packaged brace-expansion dependency to 5.0.7 (#6896 by @​davidbrai).
• Fixed persisted remote model catalogs from overriding newer bundled catalogs after an upgrade.
• Fixed inherited stored API-key credentials to apply their provider-scoped env values, including Amazon Bedrock profiles (#6864 by @​cristinaponcela).
• Fixed inherited OpenAI-compatible cross-provider replay to keep tool call IDs unique when multiple calls share a provider call ID (#6854 by @​cristinaponcela).
• Fixed inherited Kimi K3 thinking levels to expose low, high, and max, and normalized the k2p7 alias to kimi-for-coding.
• Fixed inherited OpenCode Go models routed through the OpenAI Responses API.
• Fixed inherited pi-ai package metadata to avoid repeated consumer lockfile changes (#6812 by @​jmfederico).
• Fixed inherited terminal shutdown to clear the editor's inverted software cursor before restoring the hardware cursor (#6790 by @​dam9000).
• Fixed inherited ANSI-aware text wrapping to recognize CRLF and CR line endings while preserving styles (#6764 by @​xz-dev).
• Fixed inherited editor paste registry corruption after deleting and undoing paste markers, preventing literal or mismatched paste markers in submitted prompts (#6844).
• Fixed sessionless OpenAI Codex WebSocket requests to use UUIDv7 request IDs (#6834 by @​xl0).
• Fixed inherited GPT-5.6 Codex models to default to the 272K context window, avoiding automatic long-context pricing (#6853 by @​aadishv).
• Fixed messages queued during compaction to preserve steering and follow-up delivery behavior (#6730 by @​dannote).
• Fixed read tool errors being syntax-highlighted as if they were file contents (#6731 by @​dannote).

Changelog

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

[0.81.1] - 2026-07-21

Added

• Added retry policy support and lifecycle events for compaction and branch-summary operations in AgentHarness (#6901 by @​davidbrai).

Fixed

• Restored the Agent streamFn option and host-configurable fallback for omitted agent-loop stream functions without reintroducing a pi-ai/compat dependency (#6915).

[0.81.0] - 2026-07-21

Breaking Changes

• Changed SessionStorage to use getPathToRootOrCompaction(), require session name and statistics methods, support cursor-based entry reads, and store retained compaction tails as self-contained checkpoints (#6594 by @​cristinaponcela).
• Moved the uuidv7 export to @earendil-works/pi-ai (#6834 by @​xl0).
• Replaced the optional Agent streamFn fallback with a required streamFunction and made low-level loop stream functions required, preventing @earendil-works/pi-ai/compat and all built-in providers from entering selective-provider bundles (#6851).

Added

• Added usage metadata to tool results, compaction entries, and branch summaries in the agent harness (#6671 by @​davidbrai).

[0.80.8] - 2026-07-16

[0.80.7] - 2026-07-14

Added

• Added AgentToolResult.addedToolNames propagation to ToolResultMessage so tools introduced by a result can be loaded from that transcript point onward (#6474).

[0.80.6] - 2026-07-09

Added

• Added the max model thinking level after xhigh.

[0.80.5] - 2026-07-09

[0.80.4] - 2026-07-09
