Rewrote rhs to correctly implement the coupled Friedmann–Klein–Gordon system in ln(a) time and added numerical safeguards and unit handling. • 532ae98 2026-01-14 | feat: Add new figures for emergent gravity and update manuscript formatting. • 28ec754 2026-01-14 | Paper pipeline: two-column format, bibliography, repo migration. • be490d4 2026-01-14 | feat: Update author configuration and enhance manuscript metadata. • e653174 2026-01-14 | feat: Add manuscript on constraints for LQG predictions of the cosmological constant. • aeebc44 2026-01-14 | Repro pipeline is working end-to-end now. • 8041ea1 2026-01-14 | docs(K.27): Document hybrid integration completion; 150 OOM no-go bound. • cff43ef 2026-01-14 | Update TASKS.md: predictor-derived targets first; add roadmap and internal todo mirroring. • 86dea0b 2026-01-14 | feat(K.27): Add toy spin-foam vacuum scaffolding and predictor-independent constraints. • 8766688 2026-01-14 | Add toy spin-foam mechanism, demos, and tests; extend sweep coverage and verify tests. • c4a7190 2026-01-14 | Complete Phase K.26: LQG-constrained mechanisms. • 7169e74 2026-01-14 | Complete Phase J.24: UV completion checker. • 8cc75c1 2026-01-14 | Implement demo and sweep wiring fixes; handle exponential underflow in demos. • 4262f87 2026-01-14 | Start Phase K.25: LQG polymer holonomy corrections (exploratory). • 97e5c7e 2026-01-14 | Add J.22 fix proposal and update TASKS blocker status. • acce7ec 2026-01-14 | Complete Phase J.23: backreaction radiative stability checks. • b7830f9 2026-01-14 | Update TASKS.md to reflect repo state and mark completed phases. • da71775 2026-01-14 | 30/30 tests passing for backreaction module. • 5766630 2026-01-14 | Phase I.21 complete: Gravitational Wave standard sirens for modified gravity. • 3c1b725 2026-01-13 | H.18 Emergent Gravity — COMPLETE. Notes / highlights • Core numerical fix: src/ccw/coupled_ode.py refactor — robust evaluation of H(a) and scalar field dynamics in ln(a) time with explicit safeguards to avoid non-physical and non-finite intermediate values. This resolves test failures and improves stability. • Reproducibility: regenerated papers/lqg_cc_constraints/data/scan_results.tsv using the LQG predictor adapter and recompiled papers/lqg_cc_constraints/lqg_cc_constraints.pdf so the short paper matches the current codebase. • New features and demos: toy spin-foam vacuum mechanism, demo scripts, and tests added; expanded TASKS plan and phase completion updates. • Tests: pytest is green (all tests passing in CI on this branch at the release commit).
