> **SDL-2 v1.3 agent copy.** In every package here, `posterior_tool.npz` holds a random subset of the stored posterior rows (about half of each density and magnetic mechanism); the rows that are not shipped are reserved for hidden worlds. The hidden lot is drawn from the same posterior, never from a shipped row, and its anneal parameters come from an independent run of the same anneal fit. Sentences below that call a file byte-identical to another release describe the original release, not this copy.
**SDL-2 v1.2 episode.** These are the live campaign's supplied packages, byte for byte except that each package's computed decision rankings are omitted (see its README). In this episode `request_simulation(simulation="magnetic")` is the virtual lot described in START_HERE.md, which returns numeric hypothetical loops; it is not the C7.3 twin's model distribution.
# Supplied models — current entry point
**Current: `C7.3/`** (October 23, 2026, corrective). The shared physics tool is `ndfeb-sps-physics-tool-20261023.8.3`, and the campaign twin is `ndfeb_c7_campaign_v1` (lot `CAMPAIGN-C7.3-LOT`), which answers `request_simulation(simulation="magnetic")`.
- What changed, and what C7.3 and C7.2 correct: `C7.3/README.md`. Changes since C6: the SPS density update on #7/#8, the anneal-densification layer, stage-specific densities, one alignment input, rejection of unknown route keys, and joint-target probabilities on both magnetic paths. Inherited C7.1 corrections: segmentation-consistent annealing, one hold dependence on both magnetic paths, and `anneal_eig()` / `condition_anneal()` for anneal experiments.
- What each model consumes and what it is calibrated on: `C7.3/INVENTORY.md`.
**Superseded the same day, kept byte for byte: `C7.2/`** (`ndfeb-sps-physics-tool-20261023.8.2`). Its `condition_anneal()` keyed reading identity on the source string, so a reading entered under another source, evidence id or specimen label could count twice. Use it to reproduce C7.2 results.

**Superseded the same day, kept byte for byte: `C7/`** (`ndfeb-sps-physics-tool-20261023.8.0`). Its CAPACITY and CLOSED anneal mechanisms depend on how a program is segmented. Use it only to reproduce C7 results.

**Earlier, kept byte for byte: `C6-development/`** (C6 v2, `ndfeb-sps-physics-tool-20261018.7.0-dev`, density cutoff P3). Use it to reproduce earlier work and forecasts. Its twin family `ndfeb_c6_campaign_v1` and its virtual specimens remain records. C0–C5 sit under `library/tools/` and the source archive.

All packages load in one Python process (`import` each `ndfeb_physics_tool.py` under its own module name; each calls `load()`), so you can compare them directly. The packages are model hypotheses: neither is a measurement, and neither is a replacement for a model you adopted yourself.

C7.2 added observation identity, duplicate rejection and consistent initial-piece evolution; C7.3 resolves that identity against the released ledger. C7.1 remains unchanged for replay. P7 adds images, not a numeric calibration. See C7.3/README.md for qualified density-route conclusions.
