[Unreleased]

Added

  • Automatic releases: pull-request quality checks, rolling dev GitHub packages on successful pushes to main, and Hex package/docs publishing for non-prerelease GitHub releases whose tags match VERSION.
  • Per-test-file attribution: test-only edits gate incrementally via a compiler-tracer reference graph (Qlover.Tracer, enabled with elixirc_options + test_elixirc_options) with transitive lib closure, focused expansion runs, and fresh-export union. Non-code fixture changes and tests without reference data still fall back to the full suite, fail-closed.
  • Baseline format v4 (non-test gate inputs, per-test-file hashes, reference snapshot, lib edge graph). Older baselines are treated as invalid and trigger one full re-baseline.
  • Beam hashing ignores path-volatile chunks (Dbgi, Docs, CInf, ExCk, Line): identical sources hash equally in any checkout and pure line shifts need no fresh proof. Unreadable beams fall back to raw content hashes.
  • MIX_ENV=test guard on both tasks (same rule as mix test itself), with preferred_envs setup documented for host projects.
  • Second scratch export (--expansion-export) for the focused expansion run; both exports are unioned (same code version) and cleaned up. The expansion run passes --no-stale so host test aliases that inject --stale cannot silently empty its explicit file list, and compiled support files are excluded from it (requiring them would reload plain code over instrumented code and zero their coverage).
  • examples/demo: runnable 48-test shop plus compare.sh measuring full-suite vs incremental across 11 scenarios (table in README.md); exits non-zero on any verdict mismatch. Now also carries a hostile test: ["test --stale"] alias mirroring the labqoat convention, proving qlover's explicit --no-stale-first argv cannot be shrunk by it.
  • Shared content-addressed cache (QLOVER_CACHE_DIR, default ~/.cache/qlover): snapshots write through under content keys, missing baselines fetch and heal locally, tracer records merge across directories. Verified with a cross-directory gating test.

[0.1.0] - 2026-09-17

Added

  • mix qlover gate task with three modes: --eligible, --write-baseline, and default gating of changed beams on fresh line coverage alone.
  • mix test.qlover single-command runner: stale + gate when eligible, full + snapshot otherwise, with test-arg passthrough, managed-flag rejection, and fail-closed subprocess exit codes. cover.sh delegates to it.
  • Hermetic test suite (33 tests) covering baseline roundtrip, eligibility, gate-input drift, changed-beam pass/reject, missing export, deleted-beam pruning, single-command orchestration, and fail-closed error paths.
  • Hex packaging metadata, Apache-2.0 license, and documentation.
