# F-0 notes — the bar verdicts under the registered resampling unit (the dinner clusters)

*Written 2026-09-27 (UTC) by the COI F-0 lane; generated by `series/f0_notes.py` from `series/series.json`, `series/items.json` and the bar tests `series/ladder.py` writes (every figure computed, none typed). The brief: the lead's BRIEF-COI-F0 (plans 2026-09-26, from COI-GAPS-AND-PLAN-v2 §1 and §3 build 1); the rulings: DECISIONS D-20260926-012, D-20260927-001 and D-20260927-003.*

## 1 · What changed

- **The bars' resampling unit.** Every B-anchor and B-seat verdict in `charts/data/c3-tests.csv` was computed by resampling ITEMS (`stats.noninferiority` → `paired_diff_bootstrap`); PREREG-S0 §4.2 and KIT.lock.json (sets.c `dinner_id`) register CLUSTERS. `stats.noninferiority` now goes through `stats.paired_bootstrap` (the registered form, with the exact McNemar p), and `ladder.bar_tests` passes `kitlock.kit_set('c').clusters_of(...)` for the items it tests, in kit order: clusters (16) on the whole set, 10,000 resamples, seed 20260923 (Python random.Random), all read from `facts.PREREG_BOOTSTRAP`. The clusters are numbered by first appearance in kit order, the kit's existing convention (D-20260927-001 (1)); every record says its `unit`.
- **Both parity halves.** Each paired bar is also read on the kit-order even and odd halves (n = 54 and 54; delta 10 points by R-15's n < 100 rule; units clusters (16) and clusters (15)), each under clusters restricted to its own items. `c3-tests.csv` gains each half's diff, lo, hi, n, unit, delta and verdicts, and a `both_halves` verdict per bar: a model clears on both halves only if it clears on each.
- **At the boundary (D-20260927-003).** A verdict whose lower bound lies within one item of the set it is tested on (1/n: 1/108 = 0.0093 on the whole set, 1/54 = 0.0185 on a half) of its line (0 for 'with margin', -delta for 'matches') carries `<bar> at_boundary` = True; the ladder (`first_at_boundary`, `cheapest_at_boundary`) and C3 print it. The bar's own row (the anchor on B-anchor and B-anchor (margin), the seat on B-seat) is the bar itself: its label there is blank and it has no seed row. A label: it moves no verdict.
- **Seed rows (D-20260927-001 (2)).** Every bar bound within two items of the tested set (2/n: 0.0185 whole, 0.0370 a half) of its line prints a row in `charts/data/c3-seed-sensitivity.csv`: its lower bound at the registered seed 20260923 first, then at seeds 1-20, and at how many of those 21 seeds the verdict is the registered one. 169 rows at this build (§5).
- **Regenerated with the kit's own builder** (`python3 -B series/charts.py`; nothing hand-edited): `charts/data/c3-tests.csv`, `c3-ladder.csv`, the new `c3-seed-sensitivity.csv`, `charts/c3-ladder.svg`, `charts/c2-cost-per-correct.svg` (the staircase reads B-anchor) and `charts/CHARTS.md`. C4 and C5 do not read the bar verdicts and regenerate byte-identical.

## 2 · Reading 0's rows are untouched

Only the verdicts over the rows moved. `series/series.jsonl` sha256 `902747cd084a25980ba4db0ed6dd660b05fdcc0e3cd2b88522aed2b7be36e215`: the sha A-05 cites in PREREG-S0.md. The item vectors the tests pair (`series/items.json`) sha256 `290feb0fc86a61638d212ad89b5ed1bfd7308ba25a173e47f949bf9e75a64c18`. 135 headline six-way rows are tested, each against the anchor (`withheld-2026-10-14`) and the seat (`withheld-2026-10-14`); no strict score, n, diff or price in `c3-tests.csv` changed.

## 3 · The flips: 14 verdicts move, 11 on the anchor bars and 3 on the seat bar

Whole set, the superseded item form beside the registered cluster form (same seed, same resamples). COI-GAPS-AND-PLAN-v2 §1 counted the anchor bars only; the seat bar's flips are real flips its count left out (the lead's ruling, 2026-09-27).

## 4 · The headline receipts

- **The laptop's first B-anchor clearer under items**, `qwen2.5:32b-instruct-q4_K_M` (2024-09-17, withheld-2026-10-14): under clusters it FAILS (lo -0.0734; items -0.0463). The first under clusters is `qwen3.5:27b-q4_K_M` (2026-02-24).
- **The first open model that fits a 24 GB card and matches gpt-4-0613 on both 24 GB cards, under clusters and on both halves:** `qwen3.5:27b-q4_K_M` (weights 2026-02-24).

`lo` at the registered seed 20260923; the range over it and seeds 1-20; the verdict's agreement across those seeds. The full row (every seed's lo) is `charts/data/c3-seed-sensitivity.csv`.

- **C4's ratio intervals** (`stats.ratio_bootstrap`, called by `ladder.ratios`) still resample items; C4's caption says so. That is F-1's (`ratio.py`), not F-0's.
- **`stats.mean_bootstrap`** takes clusters; both of its callers pass them (`measures.cluster_interval` and `lanes.py`'s rep-mean interval, each via `clusters_of` in kit order). `charts.py` does not call it.
- **`series/mdc.py`** already calls `stats.paired_bootstrap` with `clusters_of` (A-05's MDC).
