v8.2.1

First published 8.2 release. The v8.2.0 candidate stopped at the Intel macOS test gate before publication; its tag remains unchanged.

FKF 8.2 makes incomplete results visible, preserves evidence through interrupted writes, and helps distinguish recently edited knowledge from historical records. Existing version 2 bases need no conversion; disposable search caches rebuild automatically.

Added

• search --changed-since and --current in the CLI, MCP and retrieval cases, with active, disabled and historical source coverage, freshness and change counts.
• Reserved record attributes updated, observed and partial distinguish upstream revision, collection time and incomplete content from event time.
• Scoped local document extraction and optional Calendar agenda snapshots in the standalone collector examples.

Fixed

• Select test timezones before Python starts, preserving all DST and shared-cache checks on builds without time.tzset(), including Intel macOS.
• Recover interrupted multi-partition commits from durable originals through explicit build, collection or backup. Serialize source runs and state updates, preserve directory entries before journal writes, and bound partitions before writing.
• Preserve newer upstream revisions during backfills, repair duplicates and corrupt caches, and retry concurrent cache replacement.
• Report skipped files and unavailable bases in search; reject incomplete retrieval-case answers. Fail stale-cache health checks and skipped-file updates, reject malformed partition paths, confine link validation, and distinguish unreadable record sources from missing records.
• Correct recent and identity ordering, per-item passage selection, local-date and DST handling, and malformed-note isolation. Expose identity ambiguity and OKF provenance links.
• Validate Drive snapshot response identity before accepting empty catalogs, bound provider output while subprocesses run, and cancel collector descendants on SIGTERM.

Changed

• Rewrite onboarding around a runnable first decision and a small team pilot. Clarify offline and security limits, scheduler cadence and example isolation.
• Expand failure tests, French retrieval cases and the benchmark's changed and unchanged record paths. No runtime dependencies or services added.
