Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe pull request archives evidence for historical observations associated with issues 1912–1918. It adds probe fixtures, cross-mode results, reconciliation reports, a collection tool, and a verifier. The records distinguish reproduced differences from unavailable evidence and passing controls.

Review comments at @scripts/verify-historical-evidence.ps1:
- Around line 58-61: Update the default compilation result handling in the
verifier to distinguish the three expected declaration rejections by case; fail
verification if any other recorded default compilation exits nonzero, and
require successful compilation with the existing IL verification check for all
remaining cases.
- Around line 63-65: Update the taskMode verification loop to validate each
mode’s recorded exit code and output against a fixed case expectation or
retained observation, rather than checking only that its name appears once in
taskModes. Keep defect outputs classified as evidence, not as passing
conformance results.
Review comments at @tests/fixtures/SharpTS.HistoricalEvidence/TimingEvidence.cs:
- Line 30: Update TimingEvidence.Collect to ensure the directory for reportPath
exists before File.WriteAllText writes the timing report, including when the
path is relative and timing runs alone.

Reconcile the seven bounded historical-evidence tasks from #1599. Recover the original committed programs and review outputs, rerun each named observation on product/test baseline
e622d0c88f9133d10ce6809082a3085e759fb42b, and preserve original failures, expectations, workloads, limits and missing-artifact boundaries. Thirteen confirmed remaining defects are transferred to independently scoped fix issues #1930–#1942; these evidence tasks do not implement those fixes or reopen completed metadata ownership migrations.Each task has its own commit and report under
docs/plans/archive/issue-191N-reconciliation.md, with source manifests, frozen excerpt hashes and retained execution JSON. Add an opt-in diagnostic fixture outside the default solution and a read-only retained-evidence verifier. An independent observation table pins expected declaration rejections and recorded execution results, including reproduced defects. Newly observed companion failures are recorded separately from the frozen scope.Validation on Windows / SDK 10.0.401 / runtime 10.0.12:
pwsh scripts/verify-historical-evidence.ps1validates all source hashes, manifest bindings, excerpt hashes, deployment/IL records, exact retained outputs, declaration rejections and console/numeric controls. Eleven mutation cases reject altered evidence; original and restored copied records pass. Timing collection independently writes to a fresh directory. Local report links andgit diff --checkpass.Focused local verification is not a fresh full-suite or Linux execution claim. Existing runtime implementations, parity tests and CI limits are unchanged. See
docs/plans/archive/issue-1912-1918-validation.mdfor the consolidated checks and reproduction commands.Current-head verification at
20ea3f964521075e585a248f7ff28fbd5eb52dfc: CI run 36965548091 passed both Windows/Linux full jobs, all six standalone shards, TypeScript conformance, macOS debugger smoke tests, Native AOT smoke tests, the analyzer ratchet and final gate. Desktop GUI run 36965548105 passed its change-detection gate with unrelated native jobs skipped. All three posted review findings are fixed and their threads resolved.Closes #1912
