L-lens: a real layer around Anthropic's Jacobian Lens, with a full readout and cross-leg verification
LAWLESS1987 +1: Claude Opus 5.5The Jacobian Lens (anthropics/jacobian-lens, Apache-2.0) stays the instrument, run unmodified and credited. L-lens is ours: it hashes, derives, packages and links. - jlens_snapshot.py: reads every fitted layer at every position (upstream apply's own defaults), plus upstream's use_jacobian-off baseline and the model's final logits; top-10 per cell with exact logits in jlens_raw.npz; every full [positions, vocab] tensor hashed; model revision, lens sha256, upstream commit, env and timing recorded. - llens.py: integer summaries recomputable from the raw arrays only; build / verify / show. - triad/verify_triad.py: tombstone notes and covenant task-/jlens-/llens- memories must carry the same task_id and digests as the lens leg; fails closed. fire_triad.sh runs it. - Measured on Windows/CPU: tests/test_llens.py 26 passed; stored capture equals a direct upstream apply call, 70 of 70 comparisons; e2e_triad.sh: 44 checks green, three breaks each fail by name, a broken lens appends …2406473
