Panaesthesis

Panaesthesis (Greek pan-, all + aisthesis, perception — "all-perception") is a monitoring instrument for any system with internal relations — not only neural networks. You put sensors on a system's internal parts, it measures the relations between them through the four Hodos equations, and — where the system allows it — you reshape a relation and watch the whole field reorganize.

It is software, not art. Every curve is computed from the published Hodos math, not tuned.

Two instruments:

• Hodoscope — the microscope. Watch and measure a system's internal relational life: portrait, live (and live --twin), field (every site at once), family, watch.
• Hodotome — the scalpel. Reach in, change a named relation, continue the run downstream, and measure what happened: intervene, splice / cut, the LoRA branch readout, --gif views of the run.

The four equations, in one line each:

• Diastema — how far apart two parts live, as distributions, over the run.
• Symploke — how much a relationship creates beyond its parts (surplus over the product of marginals, z-scored against a shuffle null).
• Systasis — the constitution of the parts (named, reported honestly when it does not clear).
• Chronos — lived time: how much time a process lived per step.

Connect your own system

The instrument talks to a small ModelAdapter seam, never a system directly, so a new kind of system is a new adapter of a few dozen lines. Three ship:

• npz:<path> — a numpy checkpoint (Conv / Affine / MLP).
• torch:<file.py>:<attr> — any torch.nn.Module (needs torch).
• data:<path> — bring your own data. A table of observations × parts, where each part carries a short profile: an .npz with values (or inputs) of shape (observations, parts, profile) and optional parts names. Each part becomes a sensor; the instrument maps the relations among them and lets you reshape one. Nothing about any domain is assumed — spectra, channels, sensors, flows are all just parts.

Install

Python 3, with numpy, matplotlib, pillow:

pip install numpy matplotlib pillow

torch is optional — needed only for the torch: adapter.

Quick start

Try the bundled font-free demo:

python -m hodos_monitor.app        # the desktop app: Connect -> Try the demo

Or from the command line, map every relation in a dataset you bring:

python -m hodos_monitor field --model data:your_data.npz --out ./out

where your_data.npz holds inputs of shape (observations, parts, profile). Coupled parts read closer than unrelated ones; the full matrix is written to field_metrics.json and drawn to field.png.

Portrait a model instead:

python -m hodos_monitor portrait --model npz:model.npz --out ./portraits/v1
python -m hodos_monitor portrait --model torch:mymodel.py:net --stimulus array:inputs.npz --out ./portraits/mlp

--taps early,late,output overrides the default tap choice; --n-pair N sets the Symploke pairing count.

Reshape a relation

The monitor watches; the Hodotome acts. Name specific wires to couple or cut; everything else runs bit-identical, so cause maps to effect:

python -m hodos_monitor splice --model npz:model.npz --splice 5:12 --cut 3:44 --out ./spliced/v1
python -m hodos_monitor intervene --model torch:mymodel.py:net --level head --op cut --out ./out

Each reshape is paired with a whole-field before/after map, so you see the system reorganize, not just one number move.

Honesty labels (kept on every reading)

• Compute, don't decorate — every curve is the published math, not tuned.
• Nulls as loudly as positives — a relation that does not clear its null is reported as such.
• Systasis is ghosted — it did not clear; its box stays ghosted, a reminder, not a result.
• Chronos τ is one sampling's reading — never presented as universal.
• Section caps are the input regimes we fed, not regimes the equations derived. When the computed reading does not follow them, that mismatch is the finding.
