+  figures/sec08_pairs_realism.{png,pdf}  FULL: composition L1, coverage, selected step x (ImMicro, sepsis)
+  figures/sec08_pairs_signal.{png,pdf}   TALL: ImMicro NK fraction r, sepsis logFC r, sepsis top-50 DEG
+Every plotted/quoted number is read from a score file here and written with its source to data/sec08_*.csv.
+Model: final f01 6k 1x epoch-16 checkpoint + LoRA (checked against every RUN.json).
+x axis: "0" = no LoRA training. Two zero-shot points sit there, side by side: the pretrained model fed the real bulk
+as measured (score arm zs__raw; uses no pair) and fed gene-wise calibrated bulk (zs__cal). Calibration (back as a
+comparator, user decision 2026-10-01): alpha_g = mean CPM(pseudobulk_g) / mean CPM(bulk_g) over ALL paired training
+donors of the fold (train + inner-val; tools/prepare_dataset.py `fit = fold != f`), applied as bulk CPM x alpha, then
+renormalised. So zs__cal is not pair-free: its alpha uses the same 85-86 / 65-66 donors that LoRA "all" trains and
+early-stops on. LoRA n = training pairs, and every LoRA run also early-stops on 7-8 paired inner-val donors
+(RUN.json inner_val_rows). The LoRA arms are conditioned on the real bulk (*__raw) and share one real-bulk broadcast.
+Cap-limited = ran to max_steps before the patience window closed; its late inner-val loss drop is read from
+history.json.
+When a zero-shot point lies far outside every other value of a panel (BREAK_RATIO), that panel gets a y-axis
+break with a short segment at the same data scale, instead of squeezing the LoRA curve.
+
+Equal-budget calibration (optional, drawn only if present): zero-shot + calibration with alpha fitted on exactly the
+pairs a lora_n{5,10,20,40} run saw (n training + its inner-val pairs), per fold. The scores folder is scanned for
+summary.json files (scores/<dataset>/**/summary.json, outside arms/) whose arm names match CAL_N_RE (contain "cal"
+and an n<digits> token) and carry no fine-tune tag (FT_TAGS). An arm is drawn only from a scoring call over the
+same donors as the pooled call (same reference cells, so metrics are comparable). If found, it is drawn as a second
+line across n, ending at "all" with zs__cal (alpha from the same pairs LoRA "all" saw). If none is found, only the
+two x = 0 points are drawn and a note is printed.
+
+scSemiProfiler line (optional, drawn only if present; added 2026-10-02): scSemiProfiler trained with n pairs as
+representatives (arms scsemi_n{5,10,20,40}__raw in scores/<dataset>/scsemi_budget_20261002/pooled*/) and with all
+training pairs ("all" = arm scsemi__raw of the 5-fold CV run in scores/<dataset>/scsemi_cv_20261002/pooled*/), looked up
+by tools/scsemi_results.py and drawn only for calls over the same donors and reference cells as the pooled call. If
+nothing is found, a note is printed and the figures are unchanged. DECK_FIGDIR / DECK_OUTDATA redirect the outputs and
+DECK_SCSEMI_PLAN_ROOT the scSemiProfiler lookup (synthetic presence test).

+"""Section 9 extras of the 2026-09-30 paper-summary deck: realism / diversity metrics beyond precision and coverage
+(classifier AUC, MMD^2, scSemiProfiler's E_N, precision/coverage at k = 3 / 5 / 10).
+
+CPU only: reads the per-unit outputs of plans/paired_finetune_intradataset_20260927/tools/extra_metrics.py
+(scores_extra/<ds>/{fewshot_n5/draw<j>, pooled}/{metrics.csv, en.csv, manifest.json}) and draws slide figures.
+No torch, no CUDA, no scoring. The headline definitions are the collector's (tools/collect_extra_metrics.py,
+scores_extra/README.md) and every value is checked against scores_extra/{fewshot,pooled}_headline.csv:
+  classifier AUC (kNN, RF), 1-NN accuracy, MMD^2  real side R2 (held-out real cells), no depth matching;
+                                                  control = real vs real, R2 vs R3
+  E_N                                             all cells, squared L2 (their code); control = within-sample half
+                                                  split; undefined (UB <= LB) -> left out of means, ranks last
+  precision / coverage at k = 3, 5, 10            the scorer's space (real side R1); control = R1 vs R2
+
+Outputs (deck folder; DECK_FIGDIR / DECK_OUTDATA override the folders, used by the synthetic test):
+  figures/sec09_extra_fewpair.{png,pdf}    main slide: 5 donors, kNN AUC / MMD^2 / E_N per cohort
+  figures/sec09_extra_fivefold.{png,pdf}   backup: the same for the 5-fold pooled design
+  figures/sec09_extra_ksens.{png,pdf}      backup: precision / coverage at k = 3, 5, 10 (5 donors)
+  data/sec09_extra_{fewpair,fivefold,ksens}.csv   every plotted value with its source file
+  data/sec09_extra_scsemi_status.csv       scSemiProfiler CV / equal-budget extra-metric units found or not
+  data/sec09_extra_quoted_numbers.csv      quoted numbers (flat)
+  data/sec09_extra_slide_text.json         titles, keywords, footnotes, quoted numbers (synced into
+                                           data/slides_spec.json by tools/sync_sec09_text.py)
+
+scSemiProfiler with all training pairs (5-fold CV, arm scsemi__raw): drawn in the 5-fold figure as its own bar when an
+extra-metric unit with that set exists (scores_extra/<ds>/pooled/ itself, or below scores_extra/<ds>/scsemi_cv_20261002/,
+see tools/scsemi_results.py) for the same donors and reference cells; otherwise a note is printed and nothing is drawn.
+Equal-budget units (scsemi_n<n>__raw) are only listed in the status CSV.

+"""Section 9 of the 2026-09-30 paper-summary deck: the final method in five paired cohorts,
+and scSemiProfiler trained on the same 5 donors.
+
+CPU only: reads score files, draws slide-sized figures. No torch, no CUDA, no generation, no scANVI.
+
+Data loading is imported unchanged from the benchmark's own figure script
+(plans/paired_finetune_intradataset_20260927/figures/make_figures.py: load_fewpair, load_pooled),
+so every plotted number and every scSemiProfiler acceptance check (same donor set, same reference
+sha, receipt verified) is the same as in the paper figures. Only the drawing is new.
+
+Outputs (deck folder):
+  figures/sec09_cohorts.{png,pdf}          slide a: five paired cohorts (table)
+  figures/sec09_fewpair_cells.{png,pdf}    slide b: 5 donors, cell-level metrics
+  figures/sec09_fewpair_disease.{png,pdf}  slide c: 5 donors, disease signal
+  figures/sec09_fivefold.{png,pdf}         slide d: all pairs, 5-fold pooled
+  data/sec09_*.csv                         every plotted number with its source file
+  data/sec09_slide_text.json               slide titles, keywords, footnotes (long "footnote" for the speaker
+                                           notes + one-line "footnote_short") and quoted numbers (+ sources),
+                                           all built by this script from the same data as the figures
+  data/sec09_quoted_numbers.csv            the quoted numbers as a flat table
+
+Baselines (user decisions 2026-09-30 and 2026-10-01): the no-fine-tune baseline is zero-shot on the real bulk as
+measured (few-pair arm zs_raw, pooled arm zs__raw). The gene-wise calibration comparator is back (2026-10-01) and is
+called "Zero-shot + calibration" (few-pair arm zs_cal, alpha fitted on the same 5 training donors; pooled arm zs__cal,
+alpha from each fold's training donors). The sc-only control is the sc-only fine-tune fed calibrated bulk (pooled arm
+pseudo_full__cal, "sc-only fine-tune (+ calibration)"). OFF_STORY still bans refcal / reference calibration, VAE,
+TPM, AIFI and AIDA wording in every output.
+
+Giroux (user decision 2026-10-01): severity is confounded with sex, so its disease-signal metrics (logFC r, partial r,
+top-50 DEG, broadcast) are read from scores_nosex/giroux2022/ (tools/rescore_excluding_genes.py: the same calls with
+data/sex_linked_genes/sex_linked_genes_exclude.csv excluded and the same frozen labels). Every other Giroux metric is
+asserted equal to the original scores/ files. The other cohorts use scores/ unchanged.
+
+scSemiProfiler with all training pairs (5-fold CV, arm scsemi__raw; added 2026-10-02): drawn as its own bar on the 5-fold
+slide when an accepted pooled call exists at scores/<ds>/scsemi_cv_20261002/pooled*/ (tools/scsemi_results.py: same donors,
+same reference cells, receipt not unverified). Giroux's disease metrics for it are read from
+scores_nosex/giroux2022/scsemi_cv_20261002/ when that rescore exists, else left blank ("rescore pending"). Without any
+accepted call a note is printed and the slide is unchanged. DECK_FIGDIR / DECK_OUTDATA redirect the outputs and
+DECK_SCSEMI_PLAN_ROOT the scSemiProfiler lookup (synthetic presence test).
+
+RERUN CHECKLIST (all 25 scSemiProfiler draws are scored; rerun whenever a score file changes):
+  1. /home/sj_server_1/miniforge3/bin/python3 tools/sec09_paired_validation.py   (no edits needed; must exit 0)
+  2. Rebuild the four slides from data/sec09_slide_text.json: every title, keyword line, footnote and quoted
+     number there is regenerated. Do not keep hand-copied slide text.
+  3. Look at the four PNGs again.
