Implement the countable uncle model from the Cryptarchia spec's counting-only reference rules, and make it the simulator default. Counting rules (uncles.py, measure.py): - Only the first block of a fork (parent on the producer's chain) is referenceable and countable, which makes every reference verifiable from chain data alone. - The reference window is derived from a window-absorption parameter, w_u = W_abs/f slots (W_abs in expected block-intervals, default 10, bounded W_abs <= 0.6*k), replacing the free-standing uncle_window. - Selection skips slots already occupied on the producer's chain and takes at most one uncle per slot. - The measurement pass re-checks every rule per reference and tallies rejections as deep_ref_share. The pre-redesign model is preserved behind --old on tsi-sweep and tsi-verify. Its RNG key is byte-identical to the pre-uncle_model key, so --old bit-reproduces the historical runs. Supporting changes: uncle_model and window_absorption config surface with validation (config.py, constants.py); accuracy closed form over the effective q_u (theory.py); plumbing through tsi.py, epoch.py, sweep.py, blocktree.py, metrics.py, verify.py, figures_pernode.py. Studies and figures: - configs/countable-vs-old.yaml -- delay x U grid, run under both models on the same grid. - configs/absorption-window.yaml -- accuracy vs W_abs at U=1. - scripts/plot_countable_vs_old.py renders fig30-fig33 into reports/tsi/report-figures/. Tests: tests/test_countable_counting.py (7 cases) covering first-fork eligibility, derived-window bounds, occupied-slot exclusion, and per-reference re-checking; extensions to test_uncles.py, test_config.py, test_slot_counting.py. Full fast suite: 202 passed. Also adds CLAUDE.md (graphify project instructions) and ignores editor/local-agent state plus the vendored Equi-X benchmark clone. The reports/tsi/ prose describing this model is held back for a separate editorial pass. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# Headline comparison for the countable uncle model (cryptarchia-v1-protocol.md counting

# yields deep_ref_share (the first-fork restriction's rejection rate) and q/q_eff for the

# q_u = q + (1-q) r theory overlay. Latency is in SLOTS (1 slot = 1 s).
