fix(validation): use CLR types for Core Csc ancestor checks

[hcoona]

Summary

Fix the inactive Core Csc controller's ancestor traversal: raw DirectoryInfo parents do not carry the provider-added PSIsContainer property used under StrictMode. Branch on documented CLR types while retaining every ancestor's reparse check.

Record the failed original observer and its completed initial evidence recovery. Action 0056 consumed its dedicated unit; combined build/test usage is 87/120. The Windows lifetime gate remains unresolved, and the lost original exception cannot be attributed to the source defect.

Authorization and Governing Records

The accepted Windows Slice Wave authorizes this evidence work for #108. The executed protocol is commit 698ca30f95502a4f1cf8023ef51c0fc40918a083.

Scope and Non-Goals

One inactive controller correction and its canonical evidence record. Preserve the executed active source, failed original, consumed capacity and blocked readers. No retry, activation, new observation or continuation is granted.

Record-System Impact

Update the existing experiment protocol's outcome, source finding and allocation statement alongside the inactive source correction. Existing history readers remain blocked; no successor handoff, new record family, control or Wave change is introduced.

Evidence and Reasoning

The original observer returned exit 1 with empty output. The independently admitted recovery returned exit 0; six hash-verified offline copies establish matching paired reservations and invocations, the one-unit debit and failure before a completed controller clock exchange. Missing Windows records do not establish historical no-launch or current quiescence. The protocol records exact evidence sizes and hashes.

Identity and Security Effects

Only sanitized result fields and evidence identities are documented. No account, token, consent, cache, installation or telemetry effect.

Validation

Official Microsoft PowerShell 5.1 and .NET Framework API references support the source correction. No PowerShell or experiment subject was executed. Full hk checks and final commit hooks passed, including all 32 public-build runner conformance groups. The initial actionlint invocation needed an explicit selection of the already installed ShellCheck 0.11.0; the corrected full run passed.

Review and Disposition

• Independent original recovery review: lifetime_triage; no material findings. Review SHA-256: 967b32ea0f155bd6ffed45a1950a103234ec36c112a124c107fde72643c989d4 (12,559 bytes).
• Originating source finding: collector_schema_triage. Independent triage: wave_review, true positive (confidence 9), requiring CLR type discrimination with unchanged ancestor/reparse checks; this does not establish the original exception.
• Independent source, research-evidence and record-system review: wave_review; no material findings. Review SHA-256: 8965da8a669308e8934278ccaeb10f3b82b2598dbfdeb259f6d1f3eb9fa46fe6 (6,418 bytes), binding the exact two-file diff against the accepted base (64a1e228574040b6ccaad2eedf9d8fb6a47a24e92b7ea08090e38963e5e7f9ba).
• No Wave change or mutable-source recheck trigger. Owner authorization to merge documentation changes is retained.
