pi-tasks 0.2.9

Release Notes 0.2.9

Highlight

• Fixed #12: reducer replay no longer deep-clones accumulated event history before immediately replacing that cloned history.

Large-Session Replay

Each non-snapshot transition still deep-clones mutable task state before applying the event, preserving rejection isolation and immutable reducer behavior. The clone now receives an empty events array because event history is append-only and is rebuilt from the prior history plus the current event after a successful transition.

This removes repeated cloning of historical event payloads during branch replay without changing persisted events, snapshot data, malformed-event handling, task validation, or completion gates.

Regression Coverage

A deterministic reducer regression test verifies that:

• historical events are excluded from every transition clone;
• all prior events and the new event remain in order;
• historical event references retain the existing identity semantics;
• mutable task state remains isolated from the input state; and
• a rejected transition leaves the input state unchanged.

Verification Status

• Passed the deterministic 500-event reproducer: the transition clone received zero historical events, returned 501 events in order, preserved historical references, and isolated mutable task state.
• Passed PI_SDK_ROOT=/tmp/pi-tasks-sdk-1.2.0/node_modules/@earendil-works/pi-coding-agent npm run release:check in both the release worktree and a fresh v0.2.9 clone after npm ci: strict typecheck, Biome, 89 unit tests, 7 native Pi SDK tests, build, source/dist imports, pack dry-run, clean tarball install/import, and the audit gate.
• Passed real Pi 0.87.1 source dogfood with openai-codex/gpt-5.6-sol: task creation, update, evidence, completion, duplicate-evidence rejection, ordered-step rejection, decision/blocker rendering, same-session resume, and fork replay.
• Passed live Pi TUI /tasks detail rendering and clean /quit.
• Passed the fixed English and Traditional Chinese weak-model source prompts: compound-plan rejection, future-step evidence lock, 500-character evidence budget, and single-tool task_next convergence. The fixed installed-package English prompt also returned structured task_plan recovery.
• Passed installed pi-tasks-0.2.9.tgz extension smoke: task_resume reported the empty initial state and task_plan persisted task T1 with current step T1-S1.
