The QAC--VP5 companion record gives the public-data mock-IFU observable-family bridge for the QAC finite-domain angular-momentum compensation sector of the covariant CHC framework. QAC-VP5 is a bounded mock-IFU observable-family bridge. The archived manuscript remains authoritative for exact notation, equations, assumptions, and exclusions.

QAC-VP0--VP4 progressively established public simulation/observation proxy, environment, covariance, and dual-environment harmonization surfaces. QAC-VP5 asks a different question: can the simulation and observational sides be brought closer to the same observable family? Instead of comparing only catalog-level spin or environment summaries, VP5 takes stellar-particle cutouts from IllustrisTNG and constructs a projected mock-IFU proxy, then compares that proxy family to projected MaNGA DAP/MAPS velocity-map proxies.
The scope is intentionally narrow. The result is a public-data observable-family bridge, not a finite-window QAC closure. It does not claim a theorem-level angular-momentum compensation law, a rotating Universe, total cosmic angular momentum closure, or a full structure-formation model. It also does not claim that the small VP5 sample is representative of the full MaNGA or TNG distributions.
The simulation-side data are TNG stellar-particle cutouts. The TNG public data release provides snapshots, group catalogs, subhalo catalogs, merger trees, and supplementary products, and its API supports public-access data retrieval and cutout-style retrievals for subhalo/snapshot fields [citation]. The observational-side data are MaNGA DR17 DAP/MAPS files. MaNGA DR17 is the final MaNGA release, and its DAP products include stellar kinematics, emission-line properties, and spectral-index maps derived from MaNGA datacubes [citation].
The VP5 gate board is organized as follows.
- V5-R0: TNG cutout acquisition. Fetch a preregistered small set of TNG stellar-particle cutouts and record public-source summaries. Passing label: QAC-VP5-TNG-CUTOUT-SOURCE-CHECK-SATISFIED. - V5-R1: TNG mock-IFU proxy. Project each stellar-particle cutout through the declared mock-IFU observable operator and produce one finite proxy row per cutout. Passing label: QAC-VP5-TNG-MOCKIFU-PROXY-CHECK-SATISFIED. - V5-R2: MaNGA MAPS acquisition. Fetch the declared MaNGA DR17 MAPS files. Passing label: QAC-VP5-MANGA-MAPS-SOURCE-CHECK-SATISFIED. - V5-R3: MaNGA observable proxy. Compute the projected observational proxy from MaNGA MAPS. Passing label: QAC-VP5-MANGA-OBSERVABLE-PROXY-CHECK-SATISFIED. - V5-R4: bridge summary. Compare the simulation and observational projected observable-family proxy boards and classify the bounded bridge.
The record reports all declared VP5 source and proxy labels. The exact final label board is:
- QAC-VP5-TNG-CUTOUT-SOURCE-CHECK-SATISFIED; - QAC-VP5-TNG-MOCKIFU-PROXY-CHECK-SATISFIED; - QAC-VP5-MANGA-MAPS-SOURCE-CHECK-SATISFIED; - QAC-VP5-MANGA-OBSERVABLE-PROXY-CHECK-SATISFIED; - QAC-VP5-MOCKIFU-OBSERVABLE-BRIDGE-PARTIAL.

The bridge stress is small in standardized units, while the deliberately tiny sample restricts the classification to a partial observable-family bridge. The simulation board contains five rows, and the observational board contains three rows. The result therefore establishes that the declared observable-family operators can be evaluated on both public data surfaces and compared under the declared partial bridge, not that QAC finite-window compensation has been empirically closed.

The public source basis for VP5 identifies the declared gate summary, TNG mock-IFU projection summary, MaNGA observable-proxy summary, public-source basis, source summaries, and non-claim boundary. The route type is a public-data mock/proxy observable-family bridge. Admissible interpretation: QAC-VP5-MOCKIFU-OBSERVABLE-BRIDGE-PARTIAL on the declared TNG stellar-particle cutout and MaNGA MAPS surfaces. Excluded interpretation: representative population inference, finite-window QAC closure, theorem-level compensation, rotating-Universe evidence, or full structure-formation modeling.
The TNG cutout and MaNGA MAPS public-source surfaces are large external scientific inputs. The companion source summary distinguishes the processed diagnostic boards used in the label from the larger external source surfaces. The scientific label uses only the declared processed boards and public-source boundary conditions.
The next valuable step is not to repeat the same comparison with only more rows. A larger sample would be useful as a robustness check, but it would thicken an existing lane rather than supply a new object class. A genuinely new follow-up object is a mass-weighted observable bridge. This would combine MaNGA Pipe3D or FIREFLY spatially resolved stellar-population/mass maps with MaNGA DAP velocity maps, and compare them to mass-weighted projected TNG stellar-particle cutout proxies. Such a follow-up record would test whether the observable-family bridge remains stable after replacing light/velocity-style proxies with explicitly mass-weighted projected observables.
QAC-VP5 reaches QAC-VP5-MOCKIFU-OBSERVABLE-BRIDGE-PARTIAL. The companion record states a bounded public-data bridge between TNG stellar-particle mock-IFU proxies and MaNGA projected observational proxies. It is useful because it addresses the observable-family bridge left open after environment and covariance materialization. It remains partial and does not close finite-window QAC compensation, theorem-level angular-momentum compensation, rotating-Universe behavior, or full structure-formation modeling.
