Stacked on #276 (NOT main)

Implements the 2026-10-21 engineering handoff without changing firmware wire semantics.

• C++ single-owner transport: coalesce one SHOW/PROFILE SHOW/PTP SHOW while exclusive CFG/binary transfer owns serial; dispatch only after stage release, with STOP still using the reserved priority lane. PTP STOP stays VERIFYING through deferral, never guesses OFF, retains a bounded absolute deadline and an actionable terminal error.
• QML 1024x748 compact default, 425px preferred injection table (465px cap), extra width to plots, approximately equal Phasor/Waveform heights, no frequency preset buttons; accessible PTP details icon.
• QML magnitude/angle local drafts; no 90ms live apply; idempotent commit on Enter/Tab/focus-out, invalid inline; accepted decimal comma/dot without mixed grouping reinterpretation.
• Update structural gates and native deterministic session harness with positive+negative exclusive/readback/STOP regression.

Required follow-up: exact HEAD Windows MSVC+Qt GUI/harness build, device bench, screenshot inspection (1024/1152), and confirmed setup .exe URL; CI pass is not physical acceptance. Keep PR stacked; do not merge main or publish stable release.

2026-10-23 PR hygiene disposition — SUPERSEDED, NO MERGE. Exact branch HEAD 6d81ad3abb6ebdc2abf0522661202c8d9b1af8c7 was checked with GitHub compare and is an ancestor of integration #286 at 0e6c860f61a8780d09064369de5d29eb8c1b88c5 (behind_by=0). Closed as a historical stacked checkpoint; its commits remain in the integration lineage and its branch is not deleted. This closure does NOT assert hardware acceptance or authorize merging #286. Divergent branches (especially #284's exclusive AUTO_FAILOVER commits), physical test candidate #285, and feature-unique PRs remain open for separate review.

Engineering completion checkpoint — 2026-10-22

Exact stacked HEAD: 6d81ad3abb6ebdc2abf0522661202c8d9b1af8c7, based on PR #276 HEAD b628f2a22ad887d878f84774ce2f2bcbb661fc27. PR #280 remains OPEN; no main merge or stable release.

Verified source fixes

• Exclusive canonical BIN/CFG console readbacks coalesced by kind without user-facing internal-busy toast. Safety STOP priority preserved; PTP STOP readback bounded and board-verified, no invented OFF.
• 1024x748 default, left panel 405–465px (425 preferred), balanced live Phasor/Waveform. Fixed hidden default dock settings via one-time preferences migration. Reset Dock Layout now shows both plots.
• Discovered second UX defect in Windows screenshots: injection content clipped at 1366px because root's noncompact breakpoint expanded controls even though the left pane stayed ~425px. Left controls now always use compact sizing, redundant summary removed, and PTP/quality widths bounded.
• Numeric setpoint drafts commit once on Enter/Tab/focus-out, not 90ms typing idle; comma/dot parsing with inline invalid state.

Exact-commit CI: all SUCCESS

• Qt (native session/ownership/regression): https://github.com/masarray/arstack61850/actions/runs/39684601586
• Windows lifecycle/layout: https://github.com/masarray/arstack61850/actions/runs/39684601249
• Native Windows Inno installer + firmware pairing + clean install/hot-upgrade/migration: https://github.com/masarray/arstack61850/actions/runs/39684601343
• CI Routing and Product Naming both SUCCESS.

Screenshot acceptance: Windows-built Qt renders Phasor and Waveform at 960, 1024, 1152, 1366, 1920 × DPI 100%, 125%, 150%, 175%; geometry now rejects hidden/undersized plots and injection child overflow. Artifact: arstack-studio-windows-layout-evidence (run 39684601249).

Installer artifact: arstack-studio-native-preview-win-x64-280-6d81ad3abb6ebdc2abf0522661202c8d9b1af8c7 (run 39684601343). Extracted standalone ARStack-Studio-Preview-win-x64-setup.exe SHA-256 58d0379acbc0c843d5ed140d32819a9fe282d46982163c0e3cb55e9c8f49c759; matches CI SHA256SUMS. Package PROVENANCE + firmware manifest agree on source SHA and firmware build ID 6d81ad3abb6ebdc2.

Limit: No physical ESP32-P4 bench acceptance in CI. SOURCE/smpSynch qualification, 4kfps capture and ≥1h sustained operation still require actual board + Ethernet evidence.
