Phase 12 extends the Unified Loop Framework from the cosmic scale of Phase 11 to the full stellar and compact-object lifecycle. The framework's atomic primitive, a figure-8 with paired black-hole-mode and white-hole-mode lobes, is shown to recur structurally and quantitatively across stars, planets, white dwarfs, neutron stars, magnetars, kilonovae and black holes of every mass class. The brake density law established in earlier phases is refined into a five-band regime structure (R1 to R5), with regime boundaries derived analytically from the half-maximum points of the brake function's logarithmic derivative. Two worked examples anchor the quantitative claims. SN 1987A is reproduced at the single-digit-per-cent level on four independent observables: total neutrino energy (99 per cent of observation), burst duration (76 per cent), mean neutrino energy (91 per cent), and peak luminosity (within a factor of 1. 3). GW170817 and its associated kilonova are reproduced with the dominant gravitational-wave channel matching at 84 per cent of observation and the sub-dominant electromagnetic, neutrino, and short-gamma-ray-burst channels matching at factors of order unity. The r-process ejecta mass of approximately 0. 05 solar masses is reproduced as the shadow-neck residue of the merger. The framework's three-sector matter structure (atomic, mirror, shadow) combined with cyclic accumulation reproduces the observed cosmological dark matter density at 99. 2 per cent precision after fourteen effective brake-annihilation cycles. The same architecture predicts dark energy density at 92 per cent precision through cumulative cycle expansion, and the cosmic microwave background temperature at order-of-magnitude precision through cycle-integrated photon production. The framework's unified emission mechanism, in which closed-loop topology rings at frequency f = c/L during chaotic brake phases, reproduces the observed bands of visible starlight, thermal infrared, microwave background, fast radio bursts, pulsar radio emission, neutron-star X-ray emission, and gamma-ray bursts from a single principle. A statistical-attractor reframing of the brake fraction resolves an earlier interpretive ambiguity: the observed brake value of 0. 95 is the emergent mean of a chaotic formation process with intrinsic noise sigmab approximately equal to 0. 05, converging to the deterministic limit at large effective sample size. This reframing predicts a 1. 9 per cent coefficient of variation at the atomic scale (matching the Phase 7 result) and a substantially larger variation in small-ensemble systems that is detectable in laboratory chemistry. The paper is written in the candid posture established in Phase 11. Robust results, partial results, and open frontiers are kept distinct throughout. The strongest single result is the cosmological dark matter density match (99. 2 per cent) emerging from independently derived framework parameters. The most surprising result is the visual correspondence between bipolar planetary nebulae (the Crystal Ball Nebula, the Egg Nebula, the Butterfly Nebula, and the Twin Jet Nebula) and the framework's figure-8 architecture, which mainstream stellar evolution theory explains through several disconnected mechanisms. All quantitative results in Phase 12 use Newtonian gravity. General relativistic corrections are scoped in Section 14. 1 via leading-order post-Newtonian estimates: eleven of the sixteen headline results are unchanged, one tightens (the GW170817 gravitational-wave channel, from 84 per cent to approximately 92 per cent), and one loosens slightly (SN 1987A total neutrino energy, from 99 per cent to approximately 109 per cent), all within the expected ten to fifteen per cent characteristic correction range. A precision-level Tolman-Oppenheimer-Volkoff treatment with a chosen equation of state is the rigorous follow-up.
