Return a closeable owner before prerequisite work begins. Share creation across independent callers, join the final departure and late handoffs, retain exact failed resource owners, and gate operation dispatch again after acquisition.
Keep reuse admission separate from native health. Move shared provider ownership below application workflows and consolidate failure attribution; remove the superseded lazy client.
Validation: 34 focused owner, lazy, composite and session controls; check:fast. Compiled baseline/candidate recording-provider workflow reproduces then fences dispatch after close. No native provider claim.

Deliver complete Evidence directly through MCP with required nullable analysis profiles and immutable per-server delivery settings. Bind selected environments at construction and require typed cleanup outcomes with retained retry ownership.
Remove test-only routing, duplicate session and snapshot metadata, producer-field repairs, and ambiguous provider arguments. Separate artifact byte identity from occurrence classification and retain typed source-map and partial native facts across CLI, MCP, and verifier consumers.
BREAKING CHANGE: obsolete Evidence envelopes, session aliases, incomplete snapshots, and missing normalized producer facts are no longer accepted.
