Summary

Rebuild the Windows New Loop sheet around the merged SheetFramework so Main, Goal, Timed, Turn, Composite, Templates, validation, and create outcomes follow the current macOS design.

Refs #769

Changes

• Add the five-type New Loop presentation model and type-specific copy, fields, cadence/schedule composition, recap, keyboard shortcuts, validation reasons, and responsive SheetFramework geometry.
• Extend the Windows node draft, template library, and wire encoder for Main, heartbeat cadence, goal token budgets, template attribution/follow metadata, and stable client-chosen IDs.
• Preserve custody, attachment, worktree, context-drift, Escape/focus, DPI, and fixed-footer behavior while adding exact-ID post-create selection/open and non-composite type memory.
• Add header Templates, applied-template context, goal metric/budget expanders, bounded asynchronous done-check testing, and Save as template flow.

Test plan

RED: & $env:GRAPHCODE_ZIG0152 test src\NativeForms.zig -target x86_64-windows-msvc -lc -luser32 -lgdi32 "-IC:\gcp\769\winghostty\include" --test-filter 'new loop:' -> 6/6 executed, 0 passed and 6 failed on missing Main/order/copy/recap and NewNode behavior
GREEN: & $env:GRAPHCODE_ZIG0152 test src\NativeForms.zig -target x86_64-windows-msvc -lc -luser32 -lgdi32 "-IC:\gcp\769\winghostty\include" --test-filter 'new loop:' -> all 27 tests passed; the original six RED contracts are green and twenty-one review/regression contracts were added afterward
REGRESSION: & $env:GRAPHCODE_ZIG0152 test src\NativeForms.zig -target x86_64-windows-msvc -lc -luser32 -lgdi32 "-IC:\gcp\769\winghostty\include" -> all 380 tests passed

• & $env:GRAPHCODE_ZIG0152 test src\Forms.zig -> all 179 tests passed.
• & $env:GRAPHCODE_ZIG0152 test src\TemplateLibrary.zig -> all 190 tests passed.
• & $env:GRAPHCODE_ZIG0152 test src\Wire.zig -> all 179 tests passed.
• App-focused native command with --test-filter 'new loop:' -> all 11 tests passed.
• Full App executable root -> 1,563 executed, 1,541 passed, 22 skipped, 0 failed.
• pwsh -NoProfile -File Tools\windows\Tests\WindowsShell.Tests.ps1 -ZigExecutable $env:GRAPHCODE_ZIG0152 -Shard 0 -ShardCount 3 -SectionManifest C:\gcs\769\shard0-new-loop-manifest.json -> all 21 assigned sections passed; the registered New Loop sheet root executed 2/2 tests and the issue Windows shell: 20 Zig test files (~95 tests) are never executed by any harness #424 anti-drift guard passed.
• Focused retained-request regression -> passed with two retained commands, exact create request selection, raw triggerPrompt, and heartbeatIntervalSeconds: 3600; the obsolete 100x50ms last-command poll is absent.
• Focused post-create isolation regression -> committed head lacked synchronization (RED); current gate first observes the created node's exact hashed workspace-loop-bar plus native Show in Graph, invokes that workspace action, then requires workspace markers gone and positive canvas cards before sketch/custody (GREEN). Exact shard 0 again passed all 21 assigned sections.
• Focused custody regression -> after Time creation is remembered, the reopened child-submit path selects stable Turn tile 9600 exactly once, waits for owned visible field 9104 plus exact First instruction, then preserves the existing default-instruction/backend/turnBased submission assertions. The first cancel path remains type-agnostic.
• Focused retained-custody regression -> passed with a create followed by a later recorder-overwriting command; custody wire authority now comes from the unique correlated receivedGraphCommands request, while recorder bytes remain evidence-only. Native instruction typing/readback is recorded as validated.
• Native accessibility provider reported 224 checks and 0 failures.
• pwsh -NoProfile -File Tools\windows\Tests\CustodyChild.Tests.ps1 -ZigExecutable $env:GRAPHCODE_ZIG0152 -> GraphContextMenu 2/2, NativeForms 4/4, GraphModel 2/2, App/imported custody 30/30 passed.
• zig fmt ran on all six changed Zig files; staged diff check and all nine changed-file EOL checks passed with LF.
• Local live integration retry was blocked before UIA by the scrubbed-startup harness failing to create its daemon rendezvous secret (CreateFileW, code 3); it did not exercise the Templates, recap, stable tile, or Goal validation actions. Fresh CI owns the live verification.
• Superseded hosted head e802da9f ran every App test green (1,541 passed, 22 skipped, 0 failed) in each unit shard, then all three shards failed only because NewLoopSheet.zig was missing from the issue Windows shell: 20 Zig test files (~95 tests) are never executed by any harness #424 test-root registration; this head adds the required literal test invocation. Its separate live integration passed scrubbed startup (5/5), daemon round-trip, tray, and pre-UIA cleanup before an unrelated sketch/custody card-reveal progress assertion failed.
• Final-retry hosted head 3f0122d6 proved the New Loop Time create itself: raw triggerPrompt='Summarize new commits', heartbeat cadence, daemon response/application, and rendering all passed. Its one-slot command log was immediately overwritten by the exact-ID outcome command, so the stale create poll consumed about five seconds before custody; this head instead reads the stub's retained request-ID history and does not increase any timeout. The outer failure record's deadlineMilliseconds=0 is diagnostic-only, not issue Capture action poll consumes the whole lease, leaving no budget for cleanup proof #866's capture-worker lease.
• Hosted heads 8da961fe/7ee1529f/9c3ffcd2 proved retained create dispatch in about 10ms with heartbeat 3600, then exposed an asynchronous exact-ID activation race and destination mismatch. This head waits for the exact created-node workspace and uses its native Show in Graph action, the already-proven workspace return path; it preserves activateLoop, pan progress, and canvas input.
• Hosted d807e35b proved Turn selection, native instruction typing/readback, backend switching, and stable submit fields; the remaining custody wire mismatch was another one-slot recorder overwrite. This head uses retained custody request history instead. Current main, including Stabilize remote bridge rotation test #916's remote-bridge timing stabilization and Preserve capture cleanup reserve during action polling #917's capture cleanup reserve, was signed-merged non-force.
• Hosted 95e86fb8 proved custody native typing and submit, then showed the successful exact-ID outcome adds a second correlated graph command. Head a4f1eb01 now requires exact +2 graph/request/response/retained-command deltas, selects the unique create by its applied request ID, and selects one distinct answered request whose canonical wire is exactly the new child's resumeSession; a combined create/resume mutant is refused. The gate then returns from the exact child workspace through native Show in Graph before the final child-card hit test.
• pwsh -NoProfile -File Tools\windows\Tests\ValidationRunner.Tests.ps1 -> PASS, including UiCaptureDriver 182/182. Final shard 0 rerun -> all 21 assigned sections passed, with App 1,563 executed / 1,546 passed / 17 skipped / 0 failed. Independent review found the distinct-outcome gap; the reviewed fix is included in a4f1eb01.
• Local short-root integration passed isolation 5/5, shell smoke/stress, scrubbed startup 5/5, daemon round-trip, tray, and pre-UIA cleanup; live UIA then failed earlier on the pre-existing update-banner click before reaching New Loop/custody. Cleanup verified zero owned products.
• Native GUI screenshots, physical keyboard, Narrator/screen-reader speech, and paired macOS visual review were not run. The PR remains draft and the parity ledger remains Partial pending separately admitted live evidence.
