Bind and recheck the digest-verified snapshot used by codesign, retaining cleanup ownership when its identity changes. Classify unsigned only from the exact operand-framed diagnostic so echoed caller paths cannot turn unrelated failures into signature facts.
Closes#5636
Give each signature snapshot a private child-resource scope. Its composite
root lease closes those children before removing the directory and retains
both stages across failed retries. Bind local cleanup failures to their
exact owner so child release cannot clear a failed root removal.
Replace the mixed-outcome regression that expected premature root removal.
Cover real descriptor denial, primary/cancellation preservation, MCP close
and same-connection recovery. Expose underlying real codesign test errors
before asserting result fields.
Fixes#5052
Consume shared value and exact-number projections before JSON validation
so decoded plist scalars cannot leak as ordinary dictionaries. Carry
projection limitations into signature evidence with entitlement context.
Related: #4906. Controlled command-runner regression passed. Real
codesign refused the authored non-finite entitlement; this does not claim
real entitlement support. Existing real signature CLI controls passed.
Bind signature inspection to its named domain result and retain completed facts in typed cancellation. Check cancellation after descriptor and root finalization, preserve exact caller reasons, and keep physical failures primary. Use explicit cancellation checkpoints instead of signal-state guesses.
Validate root and descriptor cleanup, retries, late root handoff, opaque reasons, provider projections, and existing real codesign/CLI controls. No real OS close-failure or Windows qualification.
Refs #4735
Use the shared resource scope and private runtime root for signature snapshots. Retain failed file-handle/root cleanup, preserve primary failures alongside cleanup diagnostics, and wait for binding operations during client close before retrying owned resources.
Validate root cleanup failure, blocked retry, repeated client close and in-flight acquisition. Existing provider/MCP/CLI tests and the real Darwin codesign ancestor-swap case pass. Dedicated native file-handle close-failure injection remains unverified.
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.
