Separate engine cleanup, investigation reset and terminal disposal in the shared application owner. Keep stable Evidence IDs and full Unknown revision history through engine close and target changes; serialize reset with all record writers and cleanup owners, optionally acknowledging a complete checkpoint before clearing. Bound retained representation without eviction.
Validation: 43 focused files / 533 distinct tests, source/type/lint/schema/documentation checks, nine genuine source cases across eight families, real Ghidra session identity and cleanup, and nine actual local Codex CLI terra/high runs with independent full-result and checkpoint audits. See docs/verification/investigation-lifecycle.md for measurements, partial attempts and verification limits.
Fixes#8347.
BREAKING CHANGE: close_binary retains investigation records. Use reset_investigation to clear them. Cross-process recovery requires an explicitly acknowledged Evidence bundle checkpoint.

* fix(mcp): name the close_binary retry for retained cleanup
A close_binary that retired its target but could not confirm cleanup
returned cleanup_incomplete with retryable: false and only the generic
"Review the reported local resources" remediation, although the session
keeps every failed owner and the next close_binary on the same connection
retries them. Agents could abandon the connection that owns the only retry.
The MCP close tool now passes its retry operation to the session. The
session binds that typed AnalysisCleanupRetry to a failed retirement only
while it retains the cleanup for its next close; the close tool binds it to
process-capture failures its own scope retains and to compositions whose
session part was offered. Projection then reports
recovery.kind=retry_cleanup and appends a conditional instruction: keep the
connection, let the condition settle or resolve it, call close_binary
without snapshot_path and check the result. The hint disappears once that
cleanup resolves. retryable keeps describing the failed operation.
One-shot CLI closes, open_binary, analysis tools and failed snapshot saves
(which keep the target open) offer no retry. Cleanup composition copies the
owner's remediation without a retry offer, so the text appears once.
Fixes#8211

* test: derive close retry guidance from its owning formatters
The new close_binary retry assertions froze ProviderCleanupError's
explanatory sentence, so a harmless wording edit would break them. The MCP
test now compares delivered remediation with analysisErrorRemediationAction
applied to the delivered typed error plus cleanupRetryRemediation. The
domain tests use the same formatters, check that unbound and released errors
carry no retry text, and check that a bound composition adds the offer once.
Recovery fields, cleanup state and retry behavior keep separate assertions.

Add shared, typed input-contract and timeout-state recovery guidance. Normalize SDK input failures within the actual MCP wire budget, preserve full diagnostics and protocol metadata, and retain original Evidence when normalized delivery would exceed the budget.
Fixes#5431.
