# The Metastable Solitude: findings from the computational campaign

The strongest positive result is now stellar: prescribed nuclear changes survive structural adjustment and can strongly alter core carbon and oxygen. The larger claim remains unestablished. No tested point supplies a complete, observationally allowed field history, distinctive observed signature, or explanation of cosmic solitude.

## What changed from the inherited study

- **Actual stars were evolved.** In the 15-solar-mass, Z=0.02 comparison, final central carbon is 0.374203 for ordinary rates, 0.748740 for a −39.9 keV Hoyle shift, and 0.002166 for +39.9 keV. These are central mass fractions, not released yields. The +200 ppm photon-direction scenario gives 0.412950, conditional on incomplete nuclear matching. [E04-summary](runs/20260927T162453968489Z-E04-summary/manifest.json)
- **Capture was substantially extended.** All four coherent terms in each published ground-state E1/E2 amplitude were calculated and thermally averaged. At 0.2 GK, the +200 ppm fixed-nuclear-input ground-state rate is about 0.65 times baseline. The paper's main-text and appendix coefficient choices disagree; no unique high-precision physical fit or complete altered-phase rate is claimed. [E02-full](runs/20260927T061740090093Z-E02-full/manifest.json), [E02-EXFOR](runs/20260927T130334139769Z-E02-EXFOR/manifest.json)
- **Screening removes the tested core effect.** The actual MESA burning profile and dense Earth share alpha in the tested M2 model. Feeding the interior field into the nuclear network recovers ordinary composition. Its photon coupling also produces an unacceptable fixed-planet force diagnostic. [E07-stellar](runs/20260927T134204118612Z-E07-stellar/manifest.json), [E07-matter](runs/20260927T141929700876Z-E07-matter/manifest.json), [E12-constraints](runs/20260927T123831205387Z-E12-constraints/manifest.json)
- **Chemistry supplies counterexamples.** Explicit H2/water scaling, nuclear-mass and relativistic corrections, and time-dependent H2 excitation were computed. A narrowly defined driven maintenance network adapts over the declared range; none of these results identifies a universal boundary for life. [E09-extended](runs/20260927T061356137462Z-E09-extended/manifest.json), [E09-function](runs/20260927T141724466374Z-E09-function/manifest.json)
- **The history problem survives.** Real-time field dynamics, thermal scenarios, expanding-space cone integrals, seeded domain evolution, observer conditioning and past-light-cone restrictions were calculated. Phase formation and an emergence/detection law are still missing. [E06-bubbles](runs/20260927T124610990053Z-E06-bubbles/manifest.json), [E08-histories](runs/20260927T071144922221Z-E08-histories/manifest.json), [E08-domains](runs/20260927T122957970444Z-E08-domains/manifest.json), [E08-field-fronts](runs/20260927T130103425275Z-E08-field-fronts/manifest.json)
- **Real data did not supply a detection.** Synthetic spectra expose calibration false positives. Conditional fits to the released ESPRESSO spectrum converge; freely fitting its 45 velocity components does not. The JINAbase analysis retains limits and repeated analyses, but a common C/O offset remains degenerate with ordinary enrichment. [E10-spectra](runs/20260927T070724025464Z-E10-spectra/manifest.json), [E10-conditional](runs/20260927T123223276223Z-E10-conditional/manifest.json), [E11-abundances](runs/20260927T124027728147Z-E11-abundances/manifest.json)

## Enrichment and identifiability

Actual winds, release times, gas transport, locked stellar material, inflow and outflow were propagated in a mass-conserving model. The affected star returns to ordinary reaction rates during helium burning; that externally prescribed history is distinct from a field theory that creates and reverses the phase. Four 15-solar-mass cohorts are a response calculation, not a cosmic initial-mass distribution. No supernova ejecta were invented.

| Temporary history | Final C/O change (dex) | Best ordinary fit: C/O and N/O residual norm (dex) | Held-out Ne/O and Mg/O residual norm (dex) |
|---|---:|---:|---:|
| early | 5.67265e-05 | 5.53102e-05 | 2.40984e-05 |
| late | 5.91021e-05 | 5.76531e-05 | 2.51192e-05 |

These internal held-out outputs share an oxygen denominator and are not independent astronomical evidence. The full residuals, design-noise choices and nuisance bounds are recorded in [E11-enrichment](runs/20260927T162544293587Z-E11-enrichment/manifest.json), [E14-integrated](runs/20260927T163106020428Z-E14-integrated/manifest.json).

The ordinary stellar mesh/time refinement alone shifts the final enrichment C/O by -1.35663e-05 dex. Each proposed wind-history signal is compared with this numerical diagnostic before interpretation; a smaller effect is not resolved by this stellar ensemble.

## Completion and remaining limits

Every one of the 102 requested tasks has a status and evidence links in [the task checklist](task-checklist.md). A completed numerical component does not complete its broader physical counterpart. Missing matched nuclear derivatives, a populated viable field history, terminal ejection models, and nonconverged free spectrum fits remain open. Larger stellar/population scans are conditional on the model-consistency gate in the supplied checklist; scan volume is not treated as cosmic probability.

See [the technical report](technical-report.md), [claim ledger](CLAIMS.json), and the [figure and animation gallery](/research/metastable/full/index.html). The earlier pilot report is preserved in `reports/pilot-20260927` and is superseded by this campaign.

## Added projects E15–E23

All nine additions now have executed components. Their full research-grade scope remains partial. The most consequential findings are an unresolved axion nuclear-source convention, a validated continuum surrogate with 256 reserved calculations, an isotope fit that preserves chronology degeneracy, and finite-inflation memory that defeats automatic equilibrium weighting. The confined-region, pocket, cooling, gravity and atomic-analogue calculations expose additional applicability gates.

See [the nine-project findings and requirements](extended-projects.md) and [extension ledger](extension-ledger.json). None supplies an allowed complete replacement mechanism or a new observed field signal.

<!-- BEGIN NEXT-PHASE EVIDENCE -->
## Adopted next-phase plan: new evidence

Five further stages passed 111 scoped checks. Independent nuclear calculations retain the source discrepancies; charged continuum controls pass; isotope kernels expose temporal and nuisance degeneracy; the specified positive-harmonic axion family fails its late-time background energy gate. No integrated viable point or new observation is established. See [next-phase findings](next-phase-findings.md), [source questions](nuclear-reproduction-questions.md), and the [diagnostic gallery](/research/metastable/full/next-phase/index.html). Full-project completion counts are unchanged.
<!-- END NEXT-PHASE EVIDENCE -->
<!-- BEGIN RESEARCH BUILDOUT -->
## Research continuation

Four additional stages passed 104 scoped checks: printed nuclear precision and independent kernels; matrix-input and norm controls; a real-ratio nonlinear chronology ridge; and consistent field/matter thermodynamics. The twenty-package execution map retains every physical gate. No matched field-to-ejecta history or new observation is established. See [findings](buildout-findings.md), [program](research-program.md), [source packet](source-input-packet.md), and [figures](/research/metastable/full/buildout/index.html).
<!-- END RESEARCH BUILDOUT -->

<!-- BEGIN EXECUTED EXPERIMENTS -->
## Executed experiments beyond prerequisite tracking

Eight new stages passed 293 scoped checks, including calibrated nuclear predictions, empirical pole matching, joint measured chronology, interacting npe-muon matter, reciprocal field dynamics, saved-shell release, reserved element predictions and thermal/gravitational modes. The cold cosine benchmark has a localized radial minimum and specified-seed dynamical access; a complete astrophysical field history remains unestablished. Ordinary alternatives absorb much of the delivered abundance contrast. [Current findings](experiment-findings.md) · [Seven figures and data](/research/metastable/full/experiments/index.html).
<!-- END EXECUTED EXPERIMENTS -->

<!-- BEGIN SPIN ISOSPIN EXPERIMENTS -->
## Spin–isospin thresholds, populations and transitions

All twelve E24–E35 identifiers now have executed components, with 251 scoped checks. [Findings](spin-isospin-findings.md), [full-protocol coverage](spin-isospin-ledger.json) and [eight figures with data](/research/metastable/full/spin-isospin/index.html) distinguish code benchmarks, conditional calculations and unmet physical acceptance. New calculations cover coupled channels, poles, weak thresholds, local field matching, triton response, weak overlaps, restricted BBN populations, conditional ignition, continuum time evolution, synthetic identifiability, a Fe57 response and the source lattice two-body sector. No observationally viable threshold-crossing field history is established.

<!-- BEGIN PUBLIC INPUT CONTINUATION -->
## Public-input continuation

An additional 132 components passed 65221 scoped checks. [Results](public-input-findings.md), [coverage and remaining work](public-input-ledger.json), and [figures with data](/research/metastable/full/public-inputs/index.html) now include released nuclear posteriors, the Bonn A/B/C source benchmark, thermal weak conversion, solved neutral reactions, charged bound states and continuum phases, full-spin four-body predictions, microscopic trinucleon currents and a fitted axial contact transferred to reserved pp fusion, evaluated cross sections, conditional abundance likelihoods, full-EOS MESA contraction, coupled deuteron threshold passage, real dineutron-search limits, measured Th229 response, a dilute finite-temperature EOS the source compact-alpha locality test and public many-nucleon CCSD benchmarks. These replace several earlier “not run” entries. They do not supply the missing field response or complete charged three-body breakup, rigorous spectator-wave remainder bounds, four-body reactions or the thermodynamic many-body limit. Neutral higher-wave amplitudes cross breakup; independently normalized quartet l=0…4 exclusive flux now agrees with a separate elastic-loss calculation at the declared energies. Charged doublet P/D/F and quartet S/P/D/F phases run below breakup. Atomic components include finite-nuclear-mass thresholds, inclusive spectator kinematics and conditional helium charge kinetics; a corrected weak lifetime remains open. Matched-density thermal Gaussian states receive normal charge-conserving stability tests and negative-mode followups, followed by 96 pp/nn/np anomalous-curvature audits at 32 selected normal minima. Colder independent audits identify np anomalous saddles at 2 MeV; a subsequent analytic-response solve and coupled stability audit accept restricted Gaussian paired local minima at that point. Exact four-nucleon canonical density correlations and local quartet occupancy remain distinct from a thermodynamic limit.

Checkpoint21 preserves all128 prior scientific components and adds four independently reviewed scoped results. Review/controller checks remain separate from author component counts.

The full141-cell finite screened-contact certificate is independently reconstructed, but its source width0.0096595478245381 fails the unchanged2e-8 target. Original source/phase gates, zero-range certification and physical flux remain unadmitted. [Certificate review](w04-full-independent-screened-certificate-review-20261008.md).

One upper neutral-even Gaussian block has all5778 columns/181 panels independently reviewed. Its represented Rayleigh interval[3.4714277938751195e-7,3.4715099061157804e-7] is entirely below the unchanged2e-6 strictminimum threshold; this is not a physical negative mode or rigorous root/operator enclosure. Three blocks remain uncomputed. [Upper-block review](w10-upper-physical-independent-review-20261008.md).

The Re-only historical calculation demonstrates quantified non-identifiability:225 chronology-strength ridge points,183 admitted under the declared4.6Gyr ceiling, and zero marginalized rank with free chronology or heterogeneous inventories. Its inventory ceiling is conditional, not an empirical confidence interval or heavy-nucleus theta constraint. [Historical inference](isotope-nonidentifiability-findings-20261008.md).

Six fixed planar collision cases reach dimensionless tau120,57000 steps and726 frames with an independent full-history review. The saved finite-box histories show rebound and two surviving walls at tau120. This is a return-controlled collision in a separate field branch, with no complete annihilation to measured pure radiation, ordinary-matter matching, formation/lifetime or infinite-volume claim.

A qualified diagnostic inventory now joins13 cached and27 fresh candidates into40 comparisons while retaining all failures and cohort provenance; it supplies no new physical state or stationary phase. The six-case tiny hydrodynamic method has separate numerical/controller reviews; its31-case production remains unreleased. The oxygen anchor and physical-flux method reviews remain finite algebra/control results, with no real oxygen eightsector correction or physical encounter production. Original20261005 methods and failed attempts remain individually accessible in the frozen catalog. Historical input gaps are attached only to named failed attempts and do not admit scientific evidence. [Tiny method review](w15-complete-tiny-method-review-20261008.md), [bounded method reviews](independent-bounded-reviews-20261008.md), [flux controller review](w27-full-method-review-findings-20261008.md).

The original fixed optical method now has a complete independent review of 103 records: 65 tables and 6,305 coefficients, 24 scalar supports and 72 coordinates, two crossing boxes and ten coordinates, and twelve physical keys with 36 jets and 1,116 components. Five bounded numerical allocations and their metadata JOIN retain the original precision and comparison gates. This adds review evidence for an existing method, with no new scientific component or independent physical confirmation. The failed reviews remain preserved. Weighted fusion, ordinary alternatives, field matching, the full physical Hessian and a minimum certificate remain open. [Complete optical method review](w22-complete-partition-review-20261008.md).

For the selected LO canonical QCD axion vacuum potential, an analytic stationary census proves only the ordinary static minimum within|theta|<=0.5 for every finite positive quark-mass ratio; the equal-mass cusp is a maximum. This scoped negative result constrains no f_a and excludes neither finite-density nor oscillatory backgrounds. Full field viability remains open. [Static census](canonical-qcd-axion-static-vacuum-census-20261008.md).
