v0.9.0

Added

• Professional packaging: pyproject.toml (version derived from the git tag via
  setuptools-scm - no drift), a global error-log console script, zero runtime
  dependencies.
• Installed-mode defaults guard (_default_base): pip-installed runs resolve
  default paths against the current directory; in-place copies keep resolving
  against the file's folder.
• CI packaging job: builds the wheel, installs it into a fresh venv, and
  smoke-tests the console script + module import.
• publish.yml: trusted publishing to PyPI, gated behind the PUBLISH_TO_PYPI
  repository variable (skipped until enabled).

v0.8.0

Fixed

• Typed entries: parse_entries() now returns ErrorEntry dataclasses (dict-compatible via __getitem__), full type hints on all functions, and a small exception vocabulary (AgentLogError / ValidationError / LockTimeoutError) — same behavior, same exit codes.

• stdin reconfigured to UTF-8 on Windows: piped unicode no longer double-encodes into the log (stdout-only reconfigure bug).

• L10: load() no longer crashes on a locked/unreadable log file (graceful OSError fallback; regression tests added).

• Concurrent --add appends no longer lose entries: the append is
  now serialized by a cross-process lock file (<log>.lock, stdlib-only,
  atomic O_CREAT|O_EXCL create with 5s wait and stale-lock recovery)
  and the log is re-read inside the lock before writing (lost-update fix).

• _extract_area() marker semantics documented and pinned by tests:
  the CI gate and the shell hooks agree on the marker (first matching
  line, last AREA:/LOG: on it — the hooks' grep -m1 + greedy sed).

• status_token() strips the en-dash as well as the em-dash (OPEN– ->
  OPEN).

• start.py active_errors() delegates to check_errors.parse_entries()
  (the canonical parser) instead of re-implementing entry splitting, so
  the boot briefing can never drift from the tool's format.

• load() reads with utf-8-sig so a BOM-prefixed log is parsed, not
  silently ignored.

Added

• Robustness tests: 100-entry fuzz, BOM / invalid UTF-8, en-dash
  statuses, an empty section-5-only log, and multi-marker precedence in
  --check-commit (last marker on the first matching line).

Docs

• Add a permanent visitor badge to the README (GitHub traffic stats
  only keep 14 days).
• README: document the lessons-clustering chain limitation, the parser's
  worst-case O(n²) on pathological logs, and LOGNAME repo-root-relative
  paths.

v0.7.0

Docs

• Add CODE_OF_CONDUCT.md (Contributor Covenant 2.1) to complete the
  community-standards checklist.

v0.6.0

Docs

• README: fix stale test count in the file listing (90 -> 117).
• Add issue templates (bug report, feature request), a pull-request
  template that enforces the (AREA: ...) log-before-fix marker, and a
  SECURITY.md policy.

v0.5.0

Added

• One-command adoption — check_errors.py --init [--target DIR]
  scaffolds errors.txt / rules.txt / notes.txt (never overwriting
  existing files), installs the commit-msg gate (backup-safe),
  health-checks the log, and runs the unit-test suite. Built-in
  minimal scaffolds kick in when only check_errors.py was copied.

v0.4.0

Docs

• README: document the PR-based shipping workflow (branch → PR →
  squash merge with the (AREA: …) marker in the title) — direct
  pushes to master are blocked by branch protection.

v0.3.0

Added

• Server-side commit-message gate — check_errors.py --check-commit
  re-runs the log-before-fix rule on a commit-message file, and the new
  commit-gate CI job applies it to every pushed commit — so a
  --no-verify bypass is caught at the server, where the flag cannot reach.
• hooks/install.sh — one-command setup for every --no-verify blocker
  (commit-msg gate, git wrapper alias, Claude Code + VS Code hooks).
  Idempotent; backs up files before changing them; self-tests the Python
  interpreter (Windows Store stubs are detected and skipped).

v0.2.0

Added

• hooks/ — harness-level --no-verify blockers — close the documented
  bypass of the commit gate at the layer where agents run:
  • block-no-verify.sh — git alias wrapper rejecting git commit --no-verify / -n.
  • block-no-verify-hook.sh + claude-code-settings.json — Claude Code
    PreToolUse hook blocking the command (exit 2, reason shown to the
    model).
  • block-no-verify-hook.sh + vscode-agent-hooks.json — VS Code agent
    hook with the same guard, self-filtering on tool_name (VS Code does
    not apply matchers).
• CI — the hook syntax check now covers every hook script
  (git-commitmsg-hook.sh and hooks/*.sh).
• LICENSE — copyright holder set.
• check_errors.py --lessons — distills recurring CAUSE keywords
  from the error log into a LESSONS LEARNED section (preview by default;
  --apply writes it into rules.txt). The agent's memory now
  compounds on its own.

v0.1.0

Initial release — a model-agnostic error-log and log-before-fix system for
AI coding agents.

Added

• Three-file system — rules.txt, errors.txt, notes.txt templates
  with placeholders for any project, plus example data that works out of the
  box (python start.py boots a fully working demo).
• check_errors.py tooling (stdlib only) — linter (template fields +
  canonical statuses FIXED | PARTIAL | OPEN | MITIGATED | WORKAROUND),
  --add scaffolder, --has-entry mechanical gate, --archive-days
  archiver (idempotent, dry-run by default), --log for any file.
• start.py session bootstrap — STEP 0 error-log health check, reading
  order, open errors, latest session note; configurable filenames.
• git-commitmsg-hook.sh — the log-before-fix git gate: blocks code
  commits whose message lacks an AREA: <text> marker matching a logged
  entry, lints the log when it is staged, and exposes env-var overrides
  (LOGNAME, PYTHON, AGENT_ERROR_LOG_DIR).
• _test_errors.py — 64 unit tests (parsing, validation, gate, add,
  archive, idempotency).
• CI — GitHub Actions workflow running the tests, linter, and hook
  syntax check on Linux and Windows across Python 3.9–3.12.
• Docs — README, AGENTS.md, CONTRIBUTING.md, MIT license.

Known limitations

• git commit --no-verify bypasses the local hook; documented with
  practical workarounds in the README.
