REUSE-WP-0015: dedup owner entries, add report gaps (T02/T03/T05)
Some checks failed
ci / validate-registry (push) Has been cancelled

Remove 17 owner-migrated capabilities from reuse-surface index (keep
activity-core stub). Add report gaps CLI, roster stats + gaps CI steps.
T01 remains operator-blocked on Gitea publish.

# Feature Availability Evaluation
## Overview
This capability evaluates whether a feature should be available for a subject in
a given context. It is the primary implementation-ready example in the sample
registry and demonstrates a D5/A4/C3/R3 vector.
## Current reuse mode
Consumers can integrate through SDK or service API artifacts in the
feature-control repository. This is implementation reuse (A4), not just planning
metadata.
## Comparison notes
Compared with `capability.registry.register`, this entry is far stronger on
availability and external evidence. Compared with
`capability.identity.vocabulary-canonicalize`, it is stronger on delivery mode
and weaker on cross-domain generalization.

# Identity Vocabulary Canonicalization
## Overview
This capability makes identity vocabulary reusable for planning across adjacent
domains. It is intentionally research-heavy and informational, illustrating a
D4/A0/C2/R0 vector that contrasts with implementation-ready entries.
## Current reuse mode
Consumers read canon, terminology, and model artifacts in the identity-canon
repository. The value is planning reuse through shared vocabulary, not runtime
integration.
## Relation to adjacent capabilities
Feature-control evaluation depends on consistent subject and tenant concepts.
This capability supports that planning layer without providing runtime identity
services itself.

# Capability-Aware Shard Adapter Contract
The bottom narrow waist of shard-wiki: a versioned interface plus a **verified** capability
profile per binding. Core logic is written once against capabilities (not per-backend), and
the conformance suite rejects profiles whose declared abilities don't match observed behaviour.
## Assessment notes
### Discovery
Fifteen spectra reduced to an orthogonal core with implication rules (CoreArchitectureBlueprint
Section 6.5); normative in TSD Section A.
### Availability
`adapters/` ships the contract, a folder adapter, and `assert_conformant`.

# Event-Sourced Coordination Journal
The keystone: coordination-canonical state (overlays, equivalence bindings, aliases, merges,
forks) is an append-only **decision log**, totally ordered per information space; the queryable
current state is a derived **fold** of the log (`derived = f(log)`). The log is git-addressable,
giving history/patch/review/backup for coordination decisions for free.
## Assessment notes
### Discovery
Resolved across the round-1/round-2 architecture reviews (CoreArchitectureBlueprint Section 8.1).
### Availability
`decision_log.py` ships an in-memory, totally-ordered log + fold; git+lease backing is planned.

# Wiki Engine with Typed Extensions
shard-wiki's planned reference first-party shard backend — a *canonical-mode shard* it
implements natively: a small core plus a stringent typed-extension framework addressing all
collected use cases, mediating conflicting requirements into a consistent whole, with per-shard
activation (activate only what you need). It is one shard type among many — not a replacement
for other engines. Per-shard activation is a candidate consumer of
`capability.feature-control.evaluate`.
## Assessment notes

Architecture authored: `shard-wiki/spec/WikiEngineCoreArchitecture.md` (small kernel +
typed-extension framework; engine = canonical-mode shard). INTENT amendment ratified
(2026-06-15, decision 84ffdb48). Extension SDK/ABI + API protocol are the next deliverables.

One principled write path: every edit drafts an overlay (a coordination-canonical event),
renders as a patch, and applies under drift checks — fast-forwarding a writable target,
keeping a local draft on a read-only target, and refusing (never clobbering) on external drift.

# Wiki Shard Orchestration
shard-wiki's core capability: orchestrate wiki-shaped content across heterogeneous *shards*
