Added

• Per-repo identity dots in the all-repos timeline — each repo gets a stable color from the same palette the branch lanes use, so interleaved commits group visually by repo instead of having to read every name.
• "Copied as AI context ✓" toast — the c shortcut now confirms (or reports failure) even when the row isn't expanded. Previously the keyboard path copied in total silence, and a failure left your previous clipboard contents in place with no hint.
• Filter-aware empty states — instead of a bare "No commits match.", the panel now names the filter that's hiding the commits ("No commits in the last 7 days. Filtered to 2 branches.") and offers one-click outs: Show all time, Clear author filter, and All branches in single-repo mode. Fixed
• The timeline no longer shows history your repos don't contain. When an agent (or you) amends or rebases, the rewritten-away commits are now reconciled out of the cache — previously they lingered forever next to their replacements, which is the one lie a sanity-check glance must never tell. Mid-scroll views update in place without losing your position, and agent bursts are no longer truncated (per-refresh caps raised from 10 to 100 commits per repo).
• Hiding a repo now actually removes its commits from the timeline and stops watching its .git — previously the rows stayed forever and new commits in the hidden repo kept re-appearing.
• Commits made on a detached HEAD (agents checking out a SHA, bisect-style loops) and commits reachable only from a tag now show up in the timeline.
• Repos found by the background discovery scan are file-watched immediately — on a fresh install, live updates used to start only after the next app launch.
• settings.json can no longer be silently wiped: concurrent writers are serialized, writes are atomic (temp file + fsync + rename), and a hand-edit typo now preserves your original as settings.json.bak instead of resetting everything to defaults on the next auto-save.
• Diff window position is restored in physical pixels — on scaled monitors it used to creep toward the bottom-right on every reopen and eventually open off-screen.
• Release-candidate tags now publish as GitHub prereleases, so an rc can never reach the in-app updater's "latest" endpoint. Changed
• Idle footprint drops sharply in agent-heavy environments: the file watcher now reacts only to actual ref movement — git status index churn and object writes during fetch/gc no longer trigger refreshes — hidden-panel refreshes only fire when rows actually changed, and the SQLite cache runs in WAL mode with migrations applied once per launch instead of replayed on every query.
• Panel summon no longer serializes up to 5,000 commit rows over IPC just to discard them — the refill reports a count and the windowed timeline pulls rows from the cache.
