 First stable release. It is the 0.1.0-rc.1 candidate (below) plus the TLS change listed here, proven end to end by the release pipeline and by the lab (107 of 107 real Log4j JNDI lookups flagged, no miss, leak or false positive).

+# Governance
+
+LogShield is a small, maintainer-led project. This page says who decides what,
+so contributors and adopters know what to expect.
+
+## Roles
+
+- **Maintainer** ([@TurlaFSB](https://github.com/TurlaFSB)): owns the roadmap,
+  reviews and merges changes, cuts releases, and handles security reports.
+- **Contributor**: anyone who opens an issue or a pull request. Contributors
+  follow [CONTRIBUTING.md](CONTRIBUTING.md) and the
+  [Code of Conduct](CODE_OF_CONDUCT.md).
+
+New maintainers are added by invitation of the current maintainer, after a
+sustained record of good changes and reviews. The rights that matter are
+repository admin, release tagging and access to private vulnerability reports.
+
+## How decisions are made
+
+- Changes go through pull requests against `main`. The branch ruleset requires
+  passing CI (lint, tests, vulnerability and supply-chain checks); the history
+  stays linear.
+- Design decisions with lasting consequences are recorded as ADRs in
+  [docs/adr](docs/adr). A change that breaks the public surface described in
+  [docs/releasing.md](docs/releasing.md) needs an ADR or a changelog entry that
+  explains it.
+- Detection changes need tests, and bypass fixes need a corpus entry. Evidence
+  decides: a rule that cannot show its false-positive rate is not merged.
+- Disagreements are settled on the pull request or issue, in public and on the
+  technical merits. The maintainer has the final say.
+
+## Releases and security
+
+Releases are cut only by tagging a commit on `main`; the signed, reproducible
+pipeline in [docs/releasing.md](docs/releasing.md) does the rest. Vulnerability
+reports follow [SECURITY.md](SECURITY.md).
+
+## Continuity
+
+There is currently one maintainer. To keep the project usable if that changes:
+everything needed to build, test, release and verify is in this repository and
+its CI; there are no secrets to hand over, because releases are signed keylessly
+by the workflow itself; and the repository can be forked and rebuilt by anyone.

+A confirmed vulnerability is published as a GitHub Security Advisory on this
