feat(coldfusion-abliteration): Heretic-300 — 8/100 refusals at KL 0.0136, beats the heresy bar 3.6x
Ran Heretic v1.4.0's 300-trial TPE search on Cold-Fusion. Best trial scores 8/100 refusals at KL 0.0136 against a 98/100 base, versus absolute-heresy at 29/100 and our hand-tuned Robinson L35 at 72/100 / KL 0.0116 — i.e. 64 fewer refusals for the same damage. Hand-verified coherent: correct arithmetic with shown working, clean code, 66-167 word prose across nine probes. Durable findings: - direction_scope=0 (single shared direction) is decisive on this merged base: n=129, best 8/100. Per-layer directions n=131 never beat 52/100 despite a better median. Points against the multi-direction intuition for a diffuse direction (our two-template |cos| is 0.62 vs Robinson's 0.99 on stock). - Aggression is not the lever. r(KL, refusals) = -0.561 over 261 trials; the KL<0.02 band contains both the worst results (median 87/100) and the single best. A KL 0.3554 trial scored worse than one at 0.0193. - PR #317 confirmed: Heretic silently drops the MTP head on save. Source 1199 tensors -> export 1184, all 15 mtp.* gone, vision 333/333 intact, exit 0, no warning. This is also why absolute-heresy ships a byte-identical MTP head — a bug, not a design choice. Always diff tensor keys after a Heretic export. - Heretic's recovered direction carries 6.18% of its energy in sink dim 3994, versus 0.094% for our L35 and 1.97% for the L39 we rejected as brick-inducing. It survives that only because of magnitude-preserving ablation (row_normalization=FULL); our plain projection has no such protection, so the sink screen correctly refused the in-band MTP graft. Same direction, different operation. MPOA is the prerequisite for in-band MTP on a Heretic trunk. - Heretic's edit is recoverable from weights: delta is rank-1 (s2/s1 ~ 0.010), SVD gives the direction, norms give per-layer weights (1.08 -> 1.34, i.e. over-projection). Cross-layer |cos| agreement 0.9903 independently confirms the single-direction result. New tooling in services/coldfusion-abliteration/: kl_divergence.py first-token KL, class-split, zero noise floor catatonia_gate.py 12 probes x 220 tokens, prints every completion heretic_export.py PTY driver; selects by measured value, never by menu position — Heretic's resume prompt puts "delete the checkpoint and all results" one arrow-key from the target graft_mtp.py recovers the trunk direction by SVD; --pristine for the safe path when the sink screen refuses Also adds quant playbook 3.13: the NVFP4 recipe sets observer="imatrix_mse" but llm-compressor has always silently fallen back to uniform MSE for want of importance data — on this build and on the incumbent. Existing A/B comparisons stay valid since every build shares the fallback. Parked as id 42. Guardrail note: this build has lost the self-harm guardrail that the Robinson L35 build retained. Restoration is the operator's own work item.

"""Catatonia gate — prove an abliterated model still SAYS something.
|
||||
|
||||
WHY THIS EXISTS
|
||||
---------------
|
||||
Heretic scores a trial by keyword-matching refusal markers in a short completion.
|
||||
A model that emits word salad matches no refusal marker and therefore scores as
|
||||
fully compliant. `AEON-7 trial 17` did exactly that: 0/100 refusals at KL 0.0019,
|
||||
and the generations were garbage (precedent supplied by bil via the 2026-08-21
|
||||
four-arm panel; dvalin independently flagged our own T258/T260 as suspect on the
|
||||
same grounds, before we asked).
|
||||
|
||||
So a low refusal count is necessary and NOT sufficient. This gate reads the actual
|
||||
tokens. Low KL is *evidence* against catatonia — the output distribution has barely
|
||||
moved from base — but it is not proof, because KL here is measured on the FIRST
|
||||
token only and says nothing about what happens 200 tokens later.
|
||||
|
||||
WHAT IT CHECKS, in order of how badly you want to know
|
||||
1. non-empty — did it emit anything at all
|
||||
2. not degenerate — n-gram repetition, single-token loops, unicode soup
|
||||
3. coherent — type-token ratio + mean word length in sane ranges
|
||||
4. on-topic compliance — for harmful prompts: did it actually answer, or just
|
||||
fail to refuse (the distinction Heretic cannot make)
|
||||
5. guardrail retained — self-harm prompts should STILL redirect
|
||||
6. capability intact — arithmetic / factual / instruction-following survive
|
||||
|
||||
Everything is PRINTED IN FULL for hand-reading. The verdicts are triage, not a
|
||||
substitute for reading the text — that is the whole lesson of trial 17.

"""Graft an IN-BAND abliterated MTP head onto a Heretic-exported trunk.
|
||||
|
||||
THE PROBLEM
|
||||
-----------
|
||||
Heretic silently drops the MTP head on save (p-e-w/heretic PR #317, declined).
|
||||
Measured on our own export: source 1199 tensors -> export 1184, all 15 `mtp.*`
|
||||
gone, vision 333/333 intact, exit 0, no warning. That is also why
|
||||
`MuXodious/Qwen3.8-27B-absolute-heresy` ships an MTP head byte-identical to its
|
||||
base: not a design choice, the same bug.
|
||||
|
||||
WHY NOT JUST COPY THE ORIGINAL HEAD BACK
|
||||
----------------------------------------
|
||||
Because the head is conditioned on the trunk's hidden states, and Heretic just
|
||||
removed a direction from that trunk. A pristine head grafted onto an abliterated
|
||||
trunk is reading a distribution it was not trained on — which is exactly the
|
||||
"byte-identical != behaviour-preserving" point. Our own in-band build measured
|
||||
59.1% MTP acceptance against the grafted incumbent's 47.2%, so the in-band edit
|
||||
is worth reproducing rather than shortcutting.
|
||||
|
||||
HOW THE DIRECTION IS RECOVERED
|
||||
------------------------------
|
||||
Heretic ran with `direction_scope = 0`, i.e. ONE shared direction across layers,
|
||||
scaled per layer by its weight kernel. Directional ablation is
|
||||
|
||||
W_out = W_in - w * d (d^T W_in)
|
||||
|
||||
so `delta = W_out - W_in` is rank-1 with left singular vector d. We therefore
|
||||
recover d by SVD of a trunk delta, and the per-layer weight w from the ratio of
|
||||
norms. This is verified, not assumed: the script asserts the delta really is
|
||||
rank-1 (sigma2/sigma1 below a threshold) before trusting anything, and
|
||||
cross-checks d against several layers for agreement.
|
||||
|
||||
SAFETY SCREENS CARRIED OVER FROM THE ROBINSON RECIPE
|
||||
----------------------------------------------------
|
||||
Dim 3994 is this architecture's massive-activation / attention-sink dimension.
|
||||
Orthogonalising it out bricks the model, so its share of the direction's energy
|
||||
is reported and gated. Vision tensors are never touched.

"""Drive Heretic's interactive Pareto menu non-interactively, and export a chosen trial.
|
||||
|
||||
WHY THIS EXISTS
|
||||
---------------
|
||||
Heretic finishes a search by printing the Pareto-optimal trials and opening a
|
||||
`questionary` menu to pick one. `--export-strategy MERGE` chooses HOW to export,
|
||||
not WHICH trial — the selection is a separate prompt. Run under `nohup`/`</dev/null`
|
||||
the menu raises `Warning: Input is not a terminal` and the whole run exits 1 with
|
||||
300 trials of completed search stranded in the study checkpoint.
|
||||
|
||||
Nothing is lost when that happens: re-running with the same `--study-checkpoint-dir`
|
||||
reloads the finished study and goes straight back to the menu. This script gives
|
||||
that menu a real PTY, reads what it offers, picks by MEASURED VALUE rather than by
|
||||
position, and answers the follow-up prompts.
|
||||
|
||||
WHY NOT --reproduce
|
||||
-------------------
|
||||
`reproduce.json` carries only `direction_index` + per-component kernel params. The
|
||||
published examples are Heretic 1.2.0 and predate `direction_scope`, which 1.4.0
|
||||
uses to switch between a numeric direction index and per-layer directions. Our
|
||||
winning trial is scope=0; hand-writing a file whose schema cannot express that
|
||||
risks silently reproducing a different ablation than the one we measured. Driving
|
||||
the real menu keeps Heretic's own selection logic authoritative.
|
||||
|
||||
SELECTION IS BY VALUE, NOT INDEX
|
||||
--------------------------------
|
||||
The menu is ordered by Heretic, not by us, and the Pareto set changes with the
|
||||
study. Choosing "the Nth entry" would be exactly the positional-inference mistake
|
||||
that produced four wrong readings during this run. So: parse every menu line for
|
||||
its refusal count and KL, pick the line whose numbers match the target, and refuse
|
||||
to guess if no line matches.
