+- "dorian v1.0.2 is live on GitHub and PyPI." — *only after both are confirmed.*
+- "dorian has one documented, reproducible real cross-PR catch on `encode/httpx`." — `docs/REAL_CATCH_LOG.md`.

+
+## Exact "one real catch" wording
+
+> On the public repo `encode/httpx` (BSD-3, frozen SHAs), a load-bearing claim sealed when
+> `requires-python` was `">=3.8"` was flipped `WARRANTED → REVOKED` (exit 4) by a real later
+> upstream PR (#3592, "Drop Python 3.8 support") while httpx's own tests stayed green and no
+> stateless per-PR review would have re-opened the original claim. One documented catch,
+> independently reproduced — not broad validation.
+
+## Evidence checklist (all verified for v1.0.2)
+
+- [x] PyPI `dorian-vwp` serves the announced version (1.0.2) — verify with `pip install dorian-vwp` after publish.
+- [x] README first install path provides `suggest-claims` and `export --in-toto`.
+- [x] README 30-second demo passes from a fresh install (verify=0, revalidate=4, REVOKED).
+- [x] No `dorian/action@main` in public copy-paste (guarded).
+- [x] Security workflow audits the project dependency set (guarded).
+- [x] Checkout steps drop credentials where unneeded.
+- [x] `export` `.warrant` filename and `suggest-claims` PEP 263 bugs fixed + regression-tested.
+- [x] Full pytest, ruff, bandit, project-scope pip-audit, build + twine check all green.
+- [x] Real catch reproduces on this build (httpx, frozen SHAs).
+- [x] Overclaim/secret scans clean.
+
+## Launch post draft (short, honest, evidence-linked)
+
+> **dorian v1.0.2 is live** (PyPI `dorian-vwp`, GitHub release). It's a deterministic, local-first,
+> token-free way to hold a change to the explicit claims someone made about it: bind a
+> natural-language claim to a checker, seal a `.warrant`, and re-check only what a later change
+> touches.
+>
+> Why it matters: a sealed claim persists across commits, so drift gets caught when a stateless
+> per-PR check wouldn't re-open the original claim.
+>
+> One documented, reproduced real catch: on `encode/httpx` (frozen SHAs), a load-bearing
+> `requires-python >=3.8` claim flipped to REVOKED when a later upstream PR raised the floor to
+> 3.9 — while httpx's own tests stayed green. Scoped: it proves one bound claim can be revoked,
+> not broad validation.
+>
+> `pip install dorian-vwp` — 30-second demo in the README.
+>
+> Note on safety: dorian is **not** a sandbox. Executable checker policies (`--deny-exec`,
+> `checker_trust: base`) are fail-closed controls, not isolation.

+# dorian 1.0.2
+
+An announcement-readiness hotfix on top of 1.0.1. **No breaking changes**: the warrant format,
+checker grammar, exit codes, and trust semantics are unchanged. The point of this release is
+public-facing coherence — one version across PyPI, README, the Action docs, and the GitHub
+release — plus two edge-case bug fixes, a real SCA-scope fix, and CI credential hardening.
+
+It resolves the post-1.0.1 use-and-see validation findings (Codex GPT-5.5 `HOTFIX_BEFORE_ANNOUNCE`).
+
+## Why this release exists
+
+1.0.1 was real on GitHub but `pip install dorian-vwp` still served **1.0.0**, while the README
+documented 1.0.1-only commands (`suggest-claims`, `export --in-toto`). 1.0.2 is published to
+PyPI so the documented install path and command surface agree with the package a new user gets.
+
+## Public-trust fixes
+
+- **PyPI coherence (FINDING-01)** — 1.0.2 is published to PyPI via the Trusted-Publisher
+  workflow, so `pip install dorian-vwp` provides the documented command surface. README,
+  release docs, and install examples point to one coherent version.
+- **Immutable Action ref (FINDING-02)** — the README Getting-Started snippet pinned
+  `dorian/action@main` (a moving target). It and the action docs now use `@v1.0.2`. A new
+  version-sync guard fails CI if `dorian/action@main` reappears in public copy-paste.
+- **SCA audits the project, not the tool (FINDING-03)** — `security.yml` ran `uvx pip-audit`,
+  which audited pip-audit's **own** isolated environment, not dorian's dependencies. It now
+  exports the resolved project set (`uv export --all-extras --dev --no-emit-project`) and audits
+  that, with a step that asserts the project deps (duckdb/anthropic/pytest) are actually present.
+- **Checkout credential hardening (FINDING-04)** — every `actions/checkout` step now sets
+  `persist-credentials: false`; none of these workflows perform authenticated git operations
+  (the release/publish lanes mint short-lived OIDC tokens, not git credentials).
+- **Release-gate determinism** — the release-gate test job disables the uv cache
+  (`enable-cache: false`) so release validation runs from a clean resolve.
+
+## Bug fixes
+
+- **`export` of an artifact literally named `*.warrant` (FINDING-05)** — `dorian export`
+  unconditionally stripped a `.warrant` suffix, so `dorian export foo.warrant` looked for the
+  wrong sidecar and failed. It now prefers reading the input as the artifact (so `foo.warrant`
+  exports its own `foo.warrant.warrant` sidecar) and only treats a `.warrant`-suffixed input as
+  a sidecar path when the artifact has no sidecar of its own. Regression-tested.
+- **`suggest-claims` on PEP 263 (non-UTF8) Python (FINDING-06)** — the file was read with a
+  hardcoded UTF-8 decode, so valid Python declaring e.g. `# -*- coding: latin-1 -*-` was
+  rejected. It now parses the file's bytes so the encoding cookie is honored; an unknown/declared-
+  wrong codec surfaces as a clear usage error, not a traceback. Regression-tested.
+- **`symbol_index` non-git robustness** — `pyproject_script_definers` reached `git ls-files`
+  unguarded, so with a precomputed definer map plus a `[project.scripts]` table a non-git
+  checkout raised `GitError` instead of degrading to `{}` (breaking the documented "non-git
+  yields {}" contract of `claim_symbol_watch_paths`). The git call is now guarded; the symbol
+  binding is preserved, only the git-dependent script-target resolution degrades. Regression-tested.
+
+## Docs / guards
+
+- **Attestation-interop example (FINDING-07)** — the in-toto example pinned a fixed
+  `"dorianVersion": "1.0.0"`; it is now version-neutral, with a guard against a hardcoded value.
+- **Stronger determinism test (FINDING-08)** — the in-toto determinism test now asserts both
+  CLI invocations succeed before comparing output bytes.
+- **Stale-wording guard (FINDING-09)** — the version-sync guard now also catches "until the PyPI
+  release" (the narrower variant that slipped past the "first PyPI release" family).
+
+## Tests & gates
+
+Full suite green at 1.0.2 (874 tracked tests, +5 new regression tests for the fixes above), ruff
+clean, bandit clean, project-scope pip-audit clean, wheel/sdist build + `twine check` pass.
+Both reproducible benchmark suites were **re-run at 1.0.2 and reproduce the 1.0.1 figures
+exactly** (large-mutation P=R=0.93; binding-lifecycle to the same content-derived `run_id`), so
+the hotfix touches no checker numeric behavior. The documented `encode/httpx` real catch was
+**independently reproduced** on this build (verify exit 0 → revalidate exit 4 → `REVOKED`,
+`httpx-python-floor-38` BROKEN).
+
+## Honest scope (unchanged)
+
+dorian has **one documented, reproduced real cross-PR catch** on frozen public SHAs — not broad
+real-world validation. The benchmark suites are reproducibility evidence on frozen fixtures only.
+`--deny-exec`/`--deny-shell` are fail-closed policies, **not** sandboxes; `checker_trust: base`
+is a checker-source trust root, not a sandbox. `suggest-claims` checks existence/value, not
+behavior (a gutted body keeps a `symbol:` claim green); the in-toto export is experimental and
+not a registered in-toto predicate. A warrant id is content-addressed and **tamper-evident**, but
+its body includes the seal timestamp, so a fresh seal yields a different id — what reproduces is
+the outcome, not the id.
