+# Milestone B Closeout Validation - 2026-06-17
+
+## Purpose
+
+Record the current internal Milestone B validation run after the status and roadmap closeout
+guards landed on `main`.
+
+This record covers the source tree's internal pre-alpha validation path only. It does not approve
+public benchmark reports, release artifacts, package publication, production positioning, or
+performance, quality, or footprint claims.
+
+## Status
+
+Status: **pass for current internal Milestone B validation, with public blockers unchanged**.
+
+## Subject
+
+- Repository: `docushell/ethos`
+- Starting HEAD before this record: `cc1fda28d68c549dbf9a478aa89cbc99df7960ca`
+- Scope: tracked source tree, committed fixtures, committed examples, CI/static guard wiring, and
+  public-boundary gates
+- Excluded: benchmark-result publication, release artifacts, package publication, production
+  positioning, and external claim wording
+
+## Commands
+
+```sh
+git switch main
+git pull --ff-only
+make milestone-b-internal-checks PYTHON=<jsonschema-venv>/bin/python
+```
+
+The aggregate target currently composes:
+
+- `fixtures/validate_fixtures.py`
+- `schemas/test_font_policy_validation.py`
+- `.github/scripts/test_execution_status.py`
+- `.github/scripts/test_roadmap_status.py`
+- `make verify-alpha`
+- `make layout-evaluator-alpha`
+- `make python-surface-test`
+- `.github/scripts/claims_gate.py`
+- `.github/scripts/readiness_gate.py public`
+- `git diff --check`
+
+## Result
+
+```text
+fixture checks green
+font policy validation tests green
+execution status tests green
+roadmap status tests green
+verify-alpha green
+layout-evaluator-alpha green
+python surface tests green
+claims gate green
+public readiness: green
+git diff --check green
+```
+
+## Remaining Boundaries
+
+- Public benchmark reports remain blocked.
+- Release artifacts and package publication remain blocked.
+- Production positioning remains blocked.
+- Performance, quality, footprint, table-quality, and parser-quality claims remain blocked.
+- Cross-platform rendered image byte equality remains unclaimed.
+- Broader parser/layout/table/OCR semantics remain future work outside this closeout record.
+
+## Follow-up
+
+Use `make milestone-b-internal-checks` as the internal closeout validation command until the next
+milestone changes the validation contract. Contract changes should update the Make target, its
+static guard, and any dated validation record that cites the target.
