Hypothesis

Keep Palette256 and pairwise LUT immutable. Place local Hebbian/anti-Hebbian updates in a distinct dynamic synaptic overlay: z <- clamp(z + η pre post [1-tanh(|z|)]).

Included

Runnable bounded/plastic update and duplicate-observation falsifier tests, plus evidence and convergence gaps. This is explicitly not a NARS revision or posterior update.

Run

cargo test --manifest-path crates/causal-edge/Cargo.toml --test palette256_hebbian_overlay_probe

Draft; no production plasticity rewrites or new CE64 bits. CI has not been observed.

Moves crates/lance-graph-contract/tests/episodic_hebb_saturation_probe.rs here from #1722. Unlike the local helpers already in this
series, it exercises the real implementation, so the series keeps its
experiment contract and gains the concrete counter-probe. #1722 is
closed as superseded once this lands.
