chore(memory): record #512 toolchain-gate outcomes for the orchestrator

Summary

Agent-memory follow-up to PR #540 (issue #512). Three deltas, no production or governance code.

  • Marks a memory RESOLVED. project_claudemd_nullable_command_diverges_from_ci.md described a live divergence between CLAUDE.md's C# toolchain commands and ci.yml. PR fix(toolchain): make the documented C# gates execute truthfully #540 eliminated that divergence, so the memory's operative advice ("reproduce ci.yml's command before accepting a nullable blocker") no longer describes the repository. The memory now leads with its resolved status and states that a future reappearance of /p:Nullable=enable or /t:Build in a documented command is a regression of Bug: nullable-gate-cannot-fail-incremental-build #512/Bug: claudemd-nullable-gate-diverges-from-ci #522, not policy.
  • Records the Bug: nullable-gate-masked-by-incremental-build #492 burn-down figure. 195 nullable errors, all attributed to UtilitiesCS.csproj, with the per-diagnostic breakdown and the explicit lower-bound qualification: the build aborted after 22 of 73 CoreCompile executions, so UtilitiesCS's dependents never compiled. Whoever sizes that epic should measure the solution-wide total rather than trusting 195.
  • Adds a new memory for the untracked coverage.xml that run_poshqc_test and direct Pester coverage runs drop at the repository root.
  • Corrects an existing memory. The analyzer-vacuity entry previously prescribed a csc.exe invocation count greater than zero as the non-vacuity acceptance. That count is zero at verbosity=normal even for genuine compiles, so the prescribed acceptance was unsatisfiable. The correct assertion is a zero count of the literal Skipping target "CoreCompile" in an MSBuild /fl log.

Why

Two of these are corrections to memories that would have actively misled a future run: one describes a defect that no longer exists, and one prescribes a check that can never pass. The third is a repeat-encounter hazard that costs a confusing formatter-count discrepancy every time a PowerShell test gate runs before a C# format gate.

What Changed

File Change
.claude/agent-memory/orchestrator/project_claudemd_nullable_command_diverges_from_ci.md Resolved-status header; #492 measurement section added; historical record retained
.claude/agent-memory/orchestrator/poshqc-test-drops-coverage-xml-at-repo-root.md New
.claude/agent-memory/orchestrator/MEMORY.md Two index lines updated, one added

Verification

  • Index is 14.3 KB, below the 17.1 KB compaction target and well below the 24.4 KB read limit.
  • Every ](*.md) link target in the index resolves to a file that exists; verified by set difference against the directory listing.
  • No conflict markers remain in the index.

Not applicable: no code changed, so no toolchain gate applies.

Backward Compatibility / Migration Notes

None. Agent-memory files are read-only inputs to future agent runs.

Risks and Mitigations

Risk Mitigation
Index conflicts with a concurrently-landing sibling The index was compacted by a sibling while this branch was in progress. This commit takes the sibling's compaction as the base and applies only the three deltas, so the diff is three lines rather than a competing rewrite. A further conflict resolves by union.
The "RESOLVED" marking becomes wrong if #540 is reverted The memory names the issue and PR that resolved it, so the claim is falsifiable against git history rather than asserted bare.

Review Guide

Read project_claudemd_nullable_command_diverges_from_ci.md first — it is the only substantive rewrite, and only its header and one new section changed. The remaining two files are one new file and a three-line index delta.

Follow-ups

None.

GitHub Auto-close

None. This is a follow-up to #540, which carries the closing references.

Three updates following the delivery of issue #512 (PR #540):

- Mark the "CLAUDE.md nullable command diverges from ci.yml" memory
  RESOLVED. The documented C# commands now match ci.yml, so the old
  advice ("reproduce ci.yml's command before accepting a nullable
  blocker") no longer describes a live divergence. A future appearance
  of `/p:Nullable=enable` or `/t:Build` in a documented command is now a
  regression of #512/#522, and the memory says so. Also records the
  measured 195-error UtilitiesCS figure, with its lower-bound
  qualification, for the #492 burn-down.
- Add a memory for the untracked `coverage.xml` that PoshQC test runs
  drop at the repository root. It is in neither .gitignore nor
  .csharpierignore, so it inflates the CSharpier file count between two
  otherwise-identical runs and can be swept into a diff by `git add -A`.
- Correct the analyzer-vacuity memory: the non-vacuity assertion must be
  a zero `Skipping target "CoreCompile"` count, not a csc.exe count.
  csc.exe occurrences are zero at verbosity=normal even for genuine
  compiles, so the previously recorded csc-count acceptance would have
  been unsatisfiable.

The index was compacted concurrently by a sibling; this commit takes the
sibling's compaction as the base and applies only the three deltas above.
