v0.3.0

Feature

• POSIX exit codes — exit 0 on match, 1 on no match, 2 on error, following the grep/ripgrep convention so seek composes naturally in shell pipelines and conditionals (if seek "TODO"; then … fi)
• Quiet by default — clean output with no noise. New -verbose / -v flag for debugging
• Fresh results after edits — consecutive saves to the same file now trigger a re-index by including file mtime and size in the state hash, fixing a class of stale result bugs
• Concurrent safety — multiple seek processes can search the same repo simultaneously without reading partially-written index data

Fix

• Git status parsing — fixed incorrect parsing of NUL-terminated records that could silently misparse repository state
• Cache directory no longer causes repeated re-indexing — .seek-cache is auto-excluded from git tracking via .git/info/exclude
• No more index gaps during re-indexing — atomic shard replacement eliminates a window where uncommitted content was temporarily invisible
• Removed GIT_OPTIONAL_LOCKS=0 — allows git to refresh its stat cache after git status, improving detection of rapid edits

Performance

• Zero-alloc context line counting
• Benchmark suite with make test-bench

Test

• 1900+ lines of new tests covering integration, concurrency, locking, and edge cases
• CI now installs universal-ctags on macOS and Linux
