PACC-Lab v0.7 — cross-geometry coordinate transfer without refitting

The v0.6 composed coordinate is frozen on one dependence geometry and applied to the other. N0/N1/N3 transfer bidirectionally on the primary protocol and 4/4 secondary seeds; N2 passes high → moderate but misses the moderate → high task-quotient gate by ≈ 0.0003 on the primary seed (2/4 secondary), while a targeted larger stress passes 3/3. Every target-local refit passes, so N2's failure is not a target-chart failure.

Research status: STABLE the current conclusions are relatively stable
Evidence level: E3 Repeated experiment
Result: MIXED
Data basis: SYNTHETIC Synthetic data and theoretical reasoning. Many now treat synthetic data as if it were real; this laboratory says the opposite deliberately — until a real hybrid model exists, an inference is only an inference, and theoretically possible is not actually possible.

Interpretation

interpretation: A shared cross-geometry coordinate with family-specific basin boundaries — neither universal invariance nor separate local charts.

Limitations

limitations: Not established: a universal geometry-invariant coordinate, transfer across a continuous dependence range, transfer to unseen cluster topology.

Reproduction

reproduction_instructions: Extract the version's FINAL bundle; python -m pytest -q; run the version's primary script with the recorded seed; docs/PACC_LAB_v0.N_RESULTS.md and docs/EXPERIMENT_PROTOCOL_v0.N.md are inside the bundle.
