"""Frozen constants for the sparse/semantic attractor probe — see
../PROTOCOL-SPARSE.md.  Pinned before any job runs.

Everything the frozen census pinned (token budget, SEQ, flow steps/seeds,
clustering threshold, count rule, colored floor, lift measurement) is
imported unchanged from `protocol.py` / `wprotocol.py`.  This module adds
only:

  1. the domain-dense corpus conditions (Q1) and their document rules,
  2. the depth-spanning block sets for the two censused models,
  3. the tail-concentration flow (Q2) — one changed ingredient, the on-set,
  4. the novelty rule against the models' existing Pile libraries,
  5. the pre-registered verdict rules.

Nothing here is chosen at runtime.

# construction: documents in dataset order, fit until >= FIT_TOKENS, held
# from the first document the fit slice never touched, both truncated to a
# multiple of SEQ.  A document is a repo file / paper / conversation.

# 3. the tail-concentration flow (Q2)
#
# The frozen census flow ascends
#     Delta(v) = E[G(v; h) | h in top-q of a_v] - E[G(v; h)]
# with q = FLOW_Q = 0.1 re-drawn inside each 1024-state batch, i.e. it
# conditions on a ~10% event.  The tail flow ascends the SAME pointwise
# conductance under a rare-event conditioning: the on-set is the TAIL_M fit
# states with the largest signed projection under the CURRENT direction.
# Everything else — optimizer, learning rate, steps, batch, clamp, seeds,
# init directions, unit projection — is the frozen flow's, unchanged.
#
# TAIL_MODE selects how that on-set is found.  `exact` re-selects the corpus
# top-M every step (one chunked projection of the whole fit slice; a few
# seconds over the 200 steps at census scale), so the flow ascends the
# pre-registered functional itself.  `reservoir` is the cheaper persistent
# approximation the plan sketched; it only ever sees the states the flow drew
# (~40% of the corpus at this budget) and is kept as a robustness line.

TAIL_Q = 0.001              # rare-event quantile (0.1%), search and measure

# their top-M states into fewer than N distinct held sequences.  The library
# group is bimodal, so group medians are reported alongside these counts.

#
# An attractor axis found here is NOVEL iff its centroid's largest absolute
# cosine against the union of the model's Pile attractor axes — raw census
# and whitened census, ALL blocks — is below JOIN_COS.  The bar is the
# clustering / identity threshold used by every census in this line of work.

#   supported iff  sum_cells n_novel >= 1  AND  one-sided Wilcoxon signed-rank
#   (trained > floor) over the 8 paired cells has p < ALPHA.
# Q1b (content).  Every novel pole that earns a detection-validated label is
#   categorised into LABEL_CATEGORIES by the judge; counts are reported with
#   exact binomial CIs.  "Semantics under a domain-dense measure" requires at
#   least one validated novel pole categorised semantic_topical.
# Q2 (sparsity in time).  Identical shape, with the tail census in place of
#   the condition census and the Pile measure throughout.
