Claude posting for Erik Darling.

CI vehicle for #5833's six triage slices. The coordinator lands the members with train-land.sh; this PR itself is never merged.

train/5833-slices = origin/dev (a57197581) plus six --no-ff merges of the members above, in landing order; every merge is clean, because each conflict was resolved inside the member that meets it. Every member moved by merge commits only (no rebase, no force push).

Conflicts and resolutions

With dev (each member got git merge origin/dev; 1, 3, 5 and 6 merged clean):

• Delete Guard-stage tests that assert spelling, slice 2 (#5833) #5842 (slice 2), Darling/Darling.Tests/McpToolsListBudgetTests.cs: the slice removed the tools/list byte ratchet (TotalCeilingBytes and its change log); dev's Alerts hand a Level 1 investigation to your own agent (#5632 Phase A) #5819 raised that constant 198_998 -> 202_044. The constant is gone in the slice, so dev's hunk goes. The served-shape checks (ConvertedHeadCap, ConvertedParameterCap and their facts) stand.
• Delete Guard-stage spelling tests, triage slice 4 (#5833) #5837 (slice 4), Darling/Darling.Tests/TsqlConventionGuardTests.cs: deleted by the slice, modified on dev by Alerts hand a Level 1 investigation to your own agent (#5632 Phase A) #5819 (five walker exemption entries). The deletion stands.

Member to member:

• Delete Guard-stage tests that assert spelling, slice 2 (#5833) #5842 (slice 2) vs Delete Guard-stage spelling tests, slice 1 (#5833) #5840 (slice 1), Darling/Darling.Tests/CommentFilterAdoptionTests.cs: slice 1 deleted the file, slice 2 trimmed its DocCommentHygieneTests entry. The deletion stands. Resolved in slice 2 by merging fix/5833-triage-1.
• Delete Guard-stage tests that assert spelling, slice 3 (#5833) #5839 (slice 3) vs slices 1 and 2: CommentFilterAdoptionTests.cs (deleted by slice 1, trimmed by slice 3: the RefreshCeilingProvenancePinTests entry and the census summary) and Darling/Darling.Tests/RepoFileAdoptionTests.cs (deleted by slice 3, trimmed by slice 2: the DocCommentHygieneTests entry and the LF roster). Both deletions stand. Resolved in slice 3 by merging fix/5833-triage-2 (which already carries slice 1).
• Slices 4, 5 and 6 merged into the chain without conflict.

Net train diff against dev: 212 files, +37 / -23,728; nothing under deprecated/, no CHANGELOG.md edit.

Gate (bash .github/scripts/pre-push.sh on the train tree)

Guard-stage totals: Darling 4613 -> 4246, Lite 1281 -> 1151. The "before" side is dev's own Guard run on a57197581 (run 38682870179: Darling Total 4613, Failed 2; Lite Total 1281, Failed 0); the brief's 4601 predates #5819 and #5830. The coordinator ruled to push with the dev-inherited RED below documented; a separate lane fixes it on dev.

  [guard-darling]    Darling.Tests  Total: 4246, Errors: 0, Failed: 2, Skipped: 0, Not Run: 0, Time: 54.108s
  [guard-lite]    Lite.Tests  Total: 1151, Errors: 0, Failed: 0, Skipped: 0, Not Run: 0, Time: 44.967s
classes: darling 266, lite 57
  [classes-darling]    Darling.Tests  Total: 2489, Errors: 0, Failed: 0, Skipped: 224, Not Run: 0, Time: 135.604s
  [classes-darling]    Darling.Tests  Total: 2607, Errors: 0, Failed: 0, Skipped: 82, Not Run: 0, Time: 25.294s
  [classes-lite]    Lite.Tests  Total: 849, Errors: 0, Failed: 0, Skipped: 0, Not Run: 0, Time: 60.900s
GATE RED: guard-darling

The two Guard failures are dev's, not the slices': EffectiveReadWindowCensusTests.EveryToolWithAWindowArgument_NotesTheWindowItRanWith and .NoDarlingRead_CallsTheSharedWindowValidatorsDirectly_UnlessRostered, both naming get_investigation_reports (DarlingMcpInvestigationTools.cs:557 calls the shared window validators directly). #5819 added that tool and #5830 (#5814) added the census; they landed back to back. Dev's own Build run 38682870179 on a57197581 fails the same two tests in its Guard job (Darling Total 4613, Failed 2). No slice touches either file, so this train neither causes nor fixes them.

Skipped counts in the class runs are live classes; no rig was brought up (CI's PostgreSQL jobs run them).

Not done

• Dev's EffectiveReadWindowCensusTests break (above) is not fixed here: it is in no member's files.
• The members' "Undecided" items are left to a later lane, as briefed.
• Comments in surviving files that still name deleted classes (for example DocCommentHygieneTests.FindRepoRoot in several doc comments, TsqlConventionGuardTests in CSharpMemberMap.cs) were left as they are: they are prose, no conflict produced them, and the gate does not flag them.
