Baseline and dependency

• Base: main 0cc882022d20f416a33433d5f29a1f8950984d85 (M2K PR M2K: ARSAS-style native All-IED live grid with Quality/IED Time and canonical read state #176 safely squash-merged).
• Scope: canonical MmsLiveTreeModel, Data Model native inspector, existing 60k+ large-model QA. No firmware, Studio, MMS decoder duplication, SCL parser fork, timer or polling.
• Initial implementation: 0dc048bb9ea33676a64e8284ca3626d70f2bf684; current exact head: 278271d7ca316d154113c1c8968339eea3a83e94.

Root cause

Generic DO child preview had no explicit displayed-value source or received provenance; companion q/t looked up same-DO siblings without matching FC. Inspector had no guard against casually treating a scalar as an angle-bearing phasor.

Implementation

• Local, bounded measurement map on existing canonical DO/DA nodes (no new semantic/cache owner).
• Only trusted/exact CDC: CMV structured cVal.mag.f/i and cVal.ang.f/i, or scalar MV/SAV numeric mag.f/i / instMag.f/i; only actual received finite numeric MX leaf values. Exact IEC alias lookup reuses existing referenceIndex_ (bounded per-candidate work; no O(all DO children) scan per displayed DA).
• Hz and TotW remain scalar even if a stray ang.f exists. No inferred multiplier, unit, or degree symbol.
• Exposes per-field exact MMS source reference; values and angles remain absent until received. Selected DA's Quality/Timestamp now limited to received companion from same FC.
• Existing DO selected-value preview reports the source DA and uses its actual sample bit (including received empty strings).
• Native QML selected attribute inspector presents these fields explicitly.

Regression

Extended ied_browser_large_model_qa with: missing phasor sample; partial phasor; invalid angle; vector+angle; same-DO wrong-FC Quality; correct Quality/Timestamp; Hz/TotW stray-angle suppression; Boolean non-measurement; untrusted CDC suppression; source-replacement evidence reset; received-empty DO source; integer CMV vector and SAV scalar alternatives.

CI & gates

Do not merge while draft/CI pending. Require exact-head native Qt build, 60k regression, Browser convergence, review + post-merge verification. Post-M2K main CI is separately pending and must be checked. No physical-IED/Windows installer claim.

Updated review checkpoint

• Codex P2 integer AnalogueValue review corrected at 278271d, new positive and negative QA added; inline review thread resolved only after source fix.
• Predecessor M2K main exact-head SCL, Qt and Release Hardening verified SUCCESS. M2L own exact-head CI remains IN PROGRESS; no completion claim until success.
