Purpose

Implement operator-approved P3 in a separate Draft PR stacked directly on P2 #711. Avoid changing concurrent MMS Write/Control, SG7 performance and Smart IP branches.

P3 scope

• Improve waveform cursor legibility: bundled Inter SemiBold 12pt callout, stronger contrast/frame and clean leader arrows (retain no dots).
• Add authentic millisecond ticks at 5ms where spacing permits; in explicit 9-2LE visual mode t=0 is the detected first rising Ua zero crossing (if available); RAW stays frame-relative. No samples retimed.
• Explicit ∠ signed measured angle in each phasor callout with existing label routing.
• Header shows selected SV publisher's byte smpSynch 0 None / 1 Local / 2 Global / unknown, with clear tooltip warning this is publisher-reported, NOT locally verified PTP/GPS.
• Compact P/PF/S/Q1 power summary and optional per-phase expanded details only for clean 8-channel 9-2LE operator-selected U/I mapping: P from paired sample mean U×I, S from total RMS product, PF=P/S, Q1 from fundamental DFT phase. Does NOT claim absolute SCL mapping or total reactive power for distorted waves.
• Make AppCodeFontFamily use bundled Inter and replace explicit code/XAML system font overrides, with separate icon/symbol exceptions as needed.

Validation gates

• Source-only now; exact-SHA Windows tests, native bridge, SV evidence validator and portable EXE artifact not yet qualified.
• New regression tests for sync state, power mathematical truth and gating, time axis reference, Inter resources, phasor labels.
• Independent ARSVIN physical screenshots (100%/150% DPI, dynamic load, harmonic waveforms, sync flag transitions) still mandatory. Draft/unmerged.

✅ P3 exact-SHA Windows acceptance checkpoint — 2026-10-23

The final P3 head under test is 9a9b0be869b220dc8f691eea9266a7c1ff40e939, stacked directly on #711 67acff3d9d082894b6dcdcb188c6f6124edba80b. CI results:

• Build ARSAS Windows run 39966287208: SUCCESS; 2,753 / 2,753 ARSAS tests pass (0 failed/0 skipped), pinned engine 24/24, native bridge 6/6, real single-file portable Windows EXE smoke and packaging passed.
• Validate SV evidence bundles 39966287207: SUCCESS.
• CI P1 Advisory 39966287643: SUCCESS.

Operator FAT candidate: Download ARSAS v1.6.40 portable EXE artifact #12507810691. SHA-256 d756add713ff718a6139c86facee2cb71c21154657b7e923219d23e552fbd864. This is newer than P2 #711 artifact #12502993801. Never represent earlier artifacts as containing P3.

Engineering acceptance caveats: The sync badge is explicitly the received publisher smpSynch, not local verified GPS/PTP. P/Q1/S/PF only compute for coherent clean 8-channel 9-2LE operator-selected I/U mapping; Q1 is fundamental reactive, P is mean paired u*i, S is true U rms * I rms, PF=P/S. Ua rising crossing is visual t=0 when detected; RAW remains frame-relative. No decoded samples/packet engine/source timestamps were changed.

Remaining FAT: User Windows screenshot must confirm readable cursor font at 100/150% DPI, phasor angle labels fit at corners, 5ms/10ms tick readability, correct source publisher sync flags and stream/hold behavior, and power math against actual ARSVIN scenarios. This PR remains DRAFT / NOT MERGED. Shared App.xaml font token overlaps #679 and #686; preserve both sides on deliberate three-way integration; FAT typography overrides touch isolated files but must be reviewed against concurrent work.

Windows FAT correction checkpoint (2026-10-24): Draft PR #715 now stacks directly on the exact P3 #714 HEAD 9a9b0be869b220dc8f691eea9266a7c1ff40e939. User's exact P3 portable screenshot caught an actual XAML root-grid defect: seven elements attempted to share five defined measurement rows, causing Power text and bottom disclaimer to collide. #715 reserves seven rows and uses a compact two-line Power summary with per-phase tooltip (no expanding over tables). In mapped 9-2LE, Ua/Ch5–8 is rendered above Ia/Ch1–4, without touching wire decoder or raw sample sequence; RAW stays Ch1–4 then Ch5–8. RAW vs V/A differences match explicit 0.001 A/count / 0.01 V/count conversion, and RAW labels now avoid claiming unverified U/I grouping. SV switching previously regenerated waveform on UI thread and cleared/refilled all measurement rows every 200ms; #715 now processes matched immutable snapshot + raw DSP off thread via single-flight latest-value work queue, commits one coherent UI update, and replaces only changed table rows. Full Windows exact-head CI is running. Keep #715 Draft/unmerged until CI and field FAT. Preserve earlier #714 cursor/phasor/timeline/sync/font work.

P0 coordination: Draft #717 stacks atop #715/#714, preserving all already-approved Inter/cursor/sync/timeline/power DSP. New change is strictly presentational UX + retained stream transition and source tests. Parent #714, Write/Control and SG7 workstream branches remain untouched and unmerged; do not advertise #714/#715 physical EXE as P0.

Closed as consolidated into the approved SMV FAT integration #725, merged to isolated checkpoint branch checkpoint/smv-tab-v1640-fat-accepted-20261024 at bcf0ceb92a4dc6081d725ce0bd0c8f60bc102cc4.

This PR's approved commit lineage is preserved by the merge-commit in #725. Exact final tested source 4b2b62f882a81988a39a2f82d1ac8ff67592be02 passed Windows tests (2784/2784), engine (24/24), native bridge (6/6), SV validator and user FAT. Closing this component PR as superseded, not claiming an individual merge into main. Original branch retained for audit. Handoff: HANDOFF_ARSAS_SMV_TAB_ACCEPTED_CHECKPOINT_2026-10-24.md.
