Feynman Files

v0.3.10 - 2026-08-01

Runtime

• Updated the bundled Pi runtime train from 0.82.1 to 0.83.0, including Pi's provider, session, package-install, headless OpenRouter sign-in, and extension model-scope improvements.
• Migrated Feynman's bundled extension runtime to Pi's TypeBox 1.3.7 contract. Extension authors must replace removed Type.Base, Type.Awaited, Type.Promise, Type.AsyncIterator, Type.Iterator, Type.Options, and Value.Mutate APIs before upgrading.
• Updated pi-web-access to 0.17.1 for bounded streamed fetches, Gemini-compatible provider schemas, and current search/extraction fixes, and updated pi-subagents to 0.38.0 for startup retries and bounded progress snapshots.

Reliability

• Retained Feynman's fail-closed manual-compaction and eager parallel-result durability repairs because the owning upstream Pi issues remain open, and bound every Pi package plus artifact verification to the coordinated 0.83.0 train.
• Adopted Pi's native llama.cpp streaming-usage fix while preserving Feynman's automatic repair of older cached model metadata, so upgrades retain token accounting without deleting models-store.json.
• Reapplied the narrow Pi shrinkwrap repairs for brace-expansion 5.0.9 and Undici 8.9.0; upstream Pi 0.83.0 still ships the affected 5.0.7 and 8.5.0 copies.
• Fixed feynman update writing user-package upgrades to a shadow npm prefix while Pi continued loading an older managed copy. Updates now target the resolved package root, reconcile stale exact-pinned core packages against Feynman's configured versions, preserve range and registry-tag selectors as unpinned sources, verify that attempted updates actually completed, and accept names such as feynman update pi-subagents; the in-app notice now points to that supported command.
• Fixed the Windows one-line installer failing on valid long archive entries. Extraction and rollback cleanup now run through a unique short temporary drive on the install volume while preserving the transactional replacement boundary.
• CLI analytics, log, and trace sends now make one attempt before opening a silent per-process circuit breaker, rather than printing PostHog transport errors into research output. The bundled Pi tracer also performs a silent status-checked HTTP preflight and skips exporter startup when Feynman's collector is blocked or returns an error. Set FEYNMAN_DEBUG=1 for the single CLI diagnostic notice or FEYNMAN_TELEMETRY=off to disable telemetry explicitly.
• PaperRank model synthesis now rejects terminal provider errors and output-token truncation even when a failed stream contains partial text, so incomplete output cannot be labeled or written as a generated synthesis.
• Restored Feynman's 15 built-in research tools to /tools and /capabilities when Pi reports their source as the top-level research-tools.ts extension, including on Windows paths.

Validation

• Added mixed-version and older/newer Pi rejection coverage, installed-package checks for all 15 Feynman tools and 9 extension commands, compilation of every installed tool schema, optional-array and malformed-null rejection through Pi's TypeBox 1.3 runtime path, managed/global package-update checks, long-path Windows installer fixtures, cached llama.cpp migration and streaming accounting checks, and exact runtime-lock and package-artifact verification.
