 The figures of record for this report are the copies checked in under [`report-figures/`](report-figures); the simulator does not commit its own generated figures. To regenerate: run the sweeps above, then copy `runs/<…>/figures/*.png` into `report-figures/`.
 
+The **evidence** is checked in too: [`data/`](data) holds the sweep outputs behind every table and figure, one directory per study, with [`data/report_numbers.py`](data/report_numbers.py) regenerating every quoted value together with its standard error directly from them. Any number in this report can therefore be checked against its source without re-running the sweeps — see [`data/README.md`](data/README.md) for what each run is and how it was sampled.

 ## Figures
 
 All twenty-two rendered figures are versioned in [`report-figures/`](report-figures): `01`–`03` propagation delay (vs degree, vs path length, vs N); `04`–`09` adversary observation and eclipse (vs `f_adv`, vs degree, and heatmaps); `10`–`11` reliability under churn (delivery and coverage); `12`–`15` deanonymization (whole-path and full, vs path length, `f_adv`, and degree); `16`–`18` linkability over time (time to link vs stake, with redundancy, and time to learn stake vs threshold); `19` the redundancy reliability-vs-anonymity trade-off in probability and `21` the same trade in delivery-vs-time-to-link; `20` the churn-percolation threshold; `22` correlated versus uniform outages. Sixteen of the twenty-two are embedded above; the other six (`04`–`06`, `09`, `11`, `13`) are alternative cuts of data already shown — for instance 11 and 20 both plot coverage against churn, and 20 supersedes 11 by walking the churn past every degree's threshold.

+# Evidence of record
+
+The sweep outputs behind every number in [the report](../README.md). The simulator does not commit
+its own `runs/` directory — these are the copies of record, kept so that any figure or table can be
+re-derived, or challenged, without re-running hours of compute.
+
+Each run directory holds the three tables the simulator writes: `propagation.parquet`,
+`adversary.parquet` and `deanon.parquet`.
+
+| directory | config | sampling | backs |
+|---|---|---|---|
+| `default/` | `configs/default.yaml` | 1 000 rounds × 8 seeds = **8 000/cell** | §3.1–§3.5 — delay, observation, eclipse, deanonymization, delivery, coverage |
+| `redundancy/` | `configs/redundancy.yaml` | 1 200 × 8 = **9 600/cell** | §3.8 — messaging redundancy R = 1…4 |
+| `percolation/` | `configs/percolation.yaml` | 800 × 8 = **6 400/cell** | §3.5 — the churn threshold `u_c = 1 − 1/(degree − 1)` |
+| `correlated-churn/` | `configs/correlated-churn.yaml` | 800 × 8 = **6 400/cell** | §3.9 — correlated AS/region outages vs uniform churn |
+| `fullscale/` | `configs/fullscale.yaml` | 64 × 3 = **192/cell** | §5 — the 10⁶ scaling check (deliberately lighter; not a source of headline numbers) |
+
+The linkability results (§3.6–§3.7) and both deanonymization rates are closed forms over these
+tables rather than separate measurements, so they have no run of their own — `pd.linkability`
+derives them and `make verify` checks them against Monte-Carlo.
+
+## Regenerating the report's numbers
+
+```
+python report_numbers.py
+```
+
+prints every quoted value with its across-topology standard error, straight from the parquets here.
+That is the fastest way to check a table in the report against its evidence. It takes optional
+paths (`report_numbers.py <default> <redundancy> <percolation>`) if you want to point it at fresh
+runs instead.
+
+## Regenerating the data itself
+
+From [`tools/simulators/blend/pd`](../../../../tools/simulators/blend/pd): `make sweep`,
+`make redundancy`, `make percolation`, `make correlated-churn`, `make sweep-fullscale`. Results
+land in that simulator's `runs/<timestamp>_<label>/`. Note that the seed streams depend on the
+configuration, so re-running reproduces the *statistics*, not bit-identical numbers, unless the
+config is unchanged — in which case it does reproduce exactly.
+
+Two runs from the same session are deliberately **not** kept: the smoke runs (throwaway, far too
+noisy to interpret) and an earlier 144-rounds/cell redundancy grid that was superseded because its
+sampling error produced a non-monotonic delivery curve — the reason `redundancy/` samples 9 600.
