Audit Items

Area	Status	Current	Target	Next action
Skill IR	pass	schema 2.0.0; targets 5	2.0 schema, root export, and target-neutral contract evidence	Keep IR as the source before target packaging.
Target Compiler	pass	5/5 targets pass	OpenAI, Claude, generic, Agent Skills compatible, and VS Code contracts generated from IR	Deepen target-native transforms when provider clients expose stronger runtime APIs.
Output Eval Lab	pass	5 cases; delta 100.0; exec 10; blind 5	with-skill/baseline, assertions, execution evidence, blind A/B, failure taxonomy	Add more real-file and adversarial holdout cases as usage grows.
Provider Holdout	external-required	model-executed 0; token-observed 0	At least one real provider-backed holdout run with observed model/timing/token metadata	Run provider-backed holdout cases with real credentials and commit only aggregate evidence.
Human Adjudication	human-required	0/5 decisions; pending 5	Real reviewer decisions recorded before claiming output review completion	Record real A/B choices in the decision template, then regenerate adjudication.
Benchmark Reproducibility	pass	artifacts 24; missing 0; failures 3	Public methodology, reproducible commands, required artifacts, and failure disclosure are machine-checkable	Keep the manifest current with every benchmark, package, and release evidence change.
Runtime Conformance	pass	5/5 targets pass	Target package structure, metadata, relative paths, and degradation notes pass	Keep target conformance fixtures updated as platform contracts change.
Trust Security	pass	secrets 0; scripts 107; help failures 0	Secrets, scripts, dependencies, permissions, and package hash are reviewable	Keep high-permission approvals scoped, expiring, and target-mapped.
Permission Metadata	pass	4/4 target probes pass; metadata fallback 4; installer enforcement 4	Packaged adapters expose explicit permission metadata, residual risks, and installer enforcement evidence when available	Preserve residual-risk notes until real native enforcement exists.
Native Permission Enforcement	external-required	native-enforced targets 0; installer-enforced targets 4	At least one target/client enforces approved permissions at runtime	Integrate a real target-client or external installer runtime guard before claiming native permission enforcement.
Skill Atlas	pass	12 skills; actionable collisions 0	Workspace catalog, route overlap, stale/owner gaps, drift, and no-route opportunities	Feed real drift data into Atlas once client telemetry is installed.
Registry Distribution	pass	zip entries 586; install failures 0; permission failures 0	Package metadata, archive checksum, package verification, and install simulation pass	Regenerate registry after package verification so checksums stay aligned.
Review Studio	pass	decision review; warnings 3; score 91	One page shows gates, evidence paths, blockers, warnings, actions, waivers, and annotations	Resolve human/external warning gates before claiming full release readiness.
Telemetry Drift	pass	events 1; risk low; recipes 5	Local-first metadata-only event contract, aggregate drift report, hook recipes, and import path	Keep raw JSONL out of distributed packages and use aggregate reports for Atlas.
Native Client Telemetry	external-required	external source events 0; adoption samples 1	A real Browser/Chrome/provider client sends production metadata events	Install a real client against the native host and import production metadata-only events.

Open Highest-Leverage Gaps

• provider-holdout (external-required): Run provider-backed holdout cases with real credentials and commit only aggregate evidence.
• human-adjudication (human-required): Record real A/B choices in the decision template, then regenerate adjudication.
• native-permission-enforcement (external-required): Integrate a real target-client or external installer runtime guard before claiming native permission enforcement.
• native-client-telemetry (external-required): Install a real client against the native host and import production metadata-only events.
