Draft capability entry (reuse-surface REUSE-WP-0017-T04, cohort 3)

Honest first-pass maturity vector grounded in README/docs/tests present
in this repo; no invented evidence. Flagged for human review before
publish. See reuse-surface history/2026-07-06-coverage-classification.md.

+# OpenCMIS Conformance-Preparation Extension
+
+## Overview
+
+`open-cmis-tck` is the CMIS conformance-preparation extension for `guide-board`, keeping CMIS-specific runner code, profiles, and capability mappings out of the generic compliance framework. It produces preparation evidence to support future compatibility reviews and certification work, not certifications itself.
+
+## Assessment notes
+
+### Discovery
+
+README documents the extension relationship to guide-board (external extension root, invoked via --extension-dir) and explicitly disclaims issuing certifications itself — it produces preparation evidence only.
+
+### Availability
+
+Python package runnable via guide-board's extension mechanism (`--extension-dir ../open-cmis-tck`); depends on a sibling guide-board checkout to function.
+
+### Completeness
+
+First-pass honest assessment from the REUSE-WP-0017 coverage campaign
+(reuse-surface). No external consumer feedback exists yet; levels reflect
+scope-vs-intent documentation quality, not internal code quality.
+
+### Reliability
+
+No production consumer telemetry exists yet; reliability level is
+intentionally conservative pending REUSE-WP-0019 reuse-telemetry evidence.
+
+## Promotion checklist
+
+- [x] ID follows `capability.<domain>.<name>` pattern
+- [x] Maturity enums match `specs/CapabilityMaturityStandard.md`
+- [x] `external_evidence` is populated separately from `maturity`
+- [ ] Relations reference valid capability IDs (none yet)
+- [x] Index entry added in `registry/indexes/capabilities.yaml`
