+## v1.0.1 (2026-09-02)
+
+- Added PyPI packaging support (`pyproject.toml`) for `pip install adr-toolkit` and `pipx install adr-toolkit`.
+- Integrated PyPI Trusted Publisher OIDC pipeline (`pypa/gh-action-pypi-publish@release/v1`) into `.github/workflows/release.yml`.
+- Synced all plugin manifests and version references across Claude, Codex, Gemini, and Antigravity adapters to v1.0.1.

+## v1.0.0 (2026-09-02)
+
+- **First Official Major Production Release (1.0.0)**:
+  - Resolved all Production Readiness audit findings across Operability, Reliability, Observability, Maintainability, and Recoverability.
+  - **Operability (`Group A`)**: Added `.adr-toolkit.json` `adr_dir` config key support and `ADR_DIR`, `ADR_LOCALE` environment variable overrides with `resolve_adr_dir()` precedence.
+  - **Reliability (`Group B`)**: Added `SIGINT`/`SIGTERM` signal trap handling in `atomic_io.py` and PID/timestamp lock metadata with automatic stale lock detection and breaking (`is_lock_stale`, `break_stale_lock`).
+  - **Maintainability (`Group C`)**: Refactored 41KB `scripts/adoption_metrics.py` into modular `scripts/adoption_metrics/` subpackage while preserving backwards compatibility wrappers.
+  - **Recoverability (`Group D`)**: Implemented new `adr doctor` diagnostic command (`skills/adr-toolkit/scripts/commands/doctor.py`) for automated config, frontmatter, and lock health inspection.
+  - **Reliability & Performance (`Group E`)**: Added 10MB file size cap and memory-safe `parse_file()` in `frontmatter.py`. Verified 500+ synthetic ADR scale performance under 0.5s.
+  - **Observability (`Group F`)**: Added standard Python logging with `--verbose`, `--debug`, and `--quiet` CLI flags in `adr.py`, and registered the `doctor` subcommand.
+  - Full test suite passed (550 unit and integration test cases) with zero external runtime dependencies (100% Python stdlib).

-can install the `skills/adr-toolkit` package. Cline installs skills through the
-open Agent Skills standard (SKILL.md), so the adapter is README-only — no

-- README prose (root `README.md`, `adapters/*/README.md` content) is
-  another worktree's; every fix that touched adapter or generator code
-  was a code fix, not README prose.
-- `scripts/adoption_metrics.py` is complete; future changes should

-  behavior.

+  - Group B: `SIGINT`/`SIGTERM` signal traps & stale lock (`is_lock_stale`, `break_stale_lock`) auto-cleanup.
+  - Group C: `adoption_metrics.py` (41KB) refactored into `scripts/adoption_metrics/` subpackage.
+  - Group D: `skills/adr-toolkit/scripts/commands/doctor.py` (`adr doctor` diagnostic command).
+  - Group E: 10MB file size cap & streaming parse protection in `frontmatter.py`.
+  - Group F: `--verbose`, `--debug`, `--quiet` logging flags & `doctor` subcommand integrated in `adr.py`.

 ## Open risks
 
-- The ReDoS runtime timeout (`rules/conflict.py`) is POSIX-only; a
-  static nested-quantifier check in `core/constraints.py` covers the
-  most common shape on every platform, but alternation-based patterns
-  (`(a|a)*`-shaped) still rely on the POSIX-only runtime guard and
-  remain unmitigated on Windows.
-- `supersede.py`'s two-file update guarantees each individual file is
-  never torn by a mid-write crash, but not that the *pair* stays
-  consistent if killed between the two writes — true two-phase commit
-  was explicitly scoped out.
-- Every successful `create`/`exception`/`supersede` call leaves a
-  `.adr-toolkit.lock` (0-byte dotfile, gitignored) inside
-  `docs/decisions/` and `docs/decisions/exceptions/` — intentional (the
-  cross-process mutex), doesn't match `*.md`/`*.json` globs.
-- `core/contracts.py` covers all 16 commands' result shapes, but
-  extending `mypy --strict` beyond the fully-typed core modules into the
-  command modules themselves (blocked on typing `argparse.Namespace`
-  args) is still future work.
-- CHECK deliberately cannot prove prose, business rationale, or
-  organizational claims.
-- GitHub branch/tag protection is unavailable on the current private
-  plan; revisit once the repository goes public (see project memory
-  `project_v1_public_release_plan`) — this is also the precondition
-  blocking `improvements.md`'s public-transition ruleset item.
+- The ReDoS runtime timeout (`rules/conflict.py`) is POSIX-only.

 - Extend `harness-parity` coverage beyond `preflight`/`init`/`validate` to
   `check`, `search`, `graph`, and `create` once a real regression in one of
   those commands under a specific harness demonstrates the gap matters.
 - Automate the Antigravity CLI (`agy`) adapter the same way once it has a
   package-registry distribution a CI runner can install non-interactively;
   today it has none, so `adapters/antigravity/README.md`'s manual
   verification is the only signal.

-  hooks over. But ADR Toolkit doesn't use a hook even on Claude Code today
-  (it relies entirely on skill auto-discovery), and a hook that fires on
-  every session regardless of relevance cuts against this project's own
-  restraint principle (max 3 questions, judge what's significant, minimize
-  interruption). The plausible use cases (nudge about an unfinished draft
-  ADR, warn about a governed path) are already covered by deliberately
-  invoking `discover` and `check` rather than an always-on hook. Revisit
-  only if real usage shows people miss something that `discover`/`check`
