+### §11.5 — Fidelity Palettes (registered, non-conforming)
+
+A **fidelity palette** reproduces a widely used external theme **exactly**, so
+Spacecraft Software tooling can meet a user who already works in it. Values are
+copied verbatim; no token is substituted, deepened, or lifted to make a number
+pass. The consequence is stated plainly: **a fidelity palette is not required to
+satisfy §11's contrast guarantee, and neither registered one does.** The ratios
+below are *the measurement, not a target*.
+
+| Palette | Slug | Canvas | Body text | Worst pairings |
+|---------|------|--------|-----------|----------------|
+| Solarized Dark | `solarized-dark` | `base03` `#002B36` | `base0` 4.75:1 | 12 below 4.5:1; `structure`/`border` 2.97:1 and `error` 2.81:1 below 3:1 on `base02` |

+
+Rules:
+
+- A project **MUST NOT** adopt a fidelity palette as its declared §11.4 palette.
+  §13 (WCAG 2.2 AA) and §18 (accessible mode) are unaffected by this section.
+- Offered as a *user-selectable* theme, a conforming palette stays the default
+  and `steelbore-mono` (§11.1.1) stays the accessible-mode path.
+- **No `-high-contrast` sibling.** Lifting the tokens would change the values the
+  palette exists to reproduce.
+- Recorded in `steelbore.toml` under `meta.fidelity-palettes`, with
+  `conformance = "non-conforming"` in each theme's `rules` table.
+- † marks a worst pairing of 3:1–4.5:1 (large text, icons, non-text UI only);
+  ‡ marks below 3:1, which carries no legible use at any size.
+
+Solarized (Ethan Schoonover, [ethanschoonover.com/solarized](https://ethanschoonover.com/solarized/))
+defines one elevated tone per mode, so `surface-alt` shares `surface`.

The printed ratios are the measurement, not a target. §11.5 bars adopting a fidelity palette as a project's §11.4 palette, keeps `steelbore-mono` as the accessible-mode path, ships no `-high-contrast` sibling, and marks the two failure bands † (3:1–4.5:1) and ‡ (below 3:1). Solarized defines one elevated tone per mode, so `surface-alt` shares `surface`. **§11.4.1 added — Reference Names:** every palette gains an additive reference name for prose (`steelbore-color-palette`, `steelboreclassic-color-palette`, `blue-color-palette`, `blackpinkpanther-color-palette`, `matrixgreen-color-palette`, `navywhite-color-palette`, `tokyonight-color-palette`, `solarizeddark-color-palette`, `solarizedlight-color-palette`), carried in `steelbore.toml` as each palette's `reference` key. Slugs are unchanged and remain the machine identifier, so no consumer breaks. `assets/steelbore.toml` → v3.1.0: 9 palettes, 17 themes, `meta.fidelity-palettes` added.
 - **v1.38 (2026-07-26):** **§4.3 corrected — the symlink runs the other way.** v1.36 required the root `LICENSE` to be a symlink into `LICENSES/`, on the premise that GitHub follows symlinks for license detection. It does not: GitHub's detector reads **git blobs**, and a symlink's blob is the target *path*, not the license text. Measured after v1.36 landed, both `Standard` and `Construct` reported `NOASSERTION` — no identified license — where sibling repos with a regular `LICENSE` file report `GPL-3.0`. Inverted: the root `LICENSE` is a **regular file** holding the verbatim primary license text, and `LICENSES/<SPDX-id>.txt` for that license is a **symlink back to it** (`ln -s ../LICENSE LICENSES/GPL-3.0-or-later.txt`). `reuse` reads the working tree through the filesystem, so it follows the link and lints clean; GitHub gets a real blob. The text still exists exactly once, so v1.36's single-source-of-truth goal is preserved and two independently maintained copies remain non-compliant. Added: the root text MUST be a **canonical, unmodified** copy as published (FSF text for the GPL family, Creative Commons text for CC-BY-SA-4.0, or the choosealicense.com copy) — reflowed or Markdown-formatted texts defeat detection even when the wording is intact. Secondary licenses in `LICENSES/` stay regular files; only the primary license is linked. §5.2 `LICENSE` row and the §16 checklist bullet updated to match.
 - **v1.37 (2026-07-26):** **Changelog extracted from the published Standard document.** The full version history moved out of §1 — Preamble into `CHANGELOG.md` at the root of the Standard repo, newest-first; the Preamble now carries a pointer to it plus the current version and date. All 37 entries (v1.0 → v1.36) were preserved verbatim. **No normative change** — every rule in force is unchanged, and this skill's encoding of the rules is untouched apart from the masthead and frontmatter version. The two changelogs (`standard/CHANGELOG.md` and this file) remain parallel records synced to the same version and date; the Standard's is canonical.
 - **v1.36 (2026-07-26):** **§4.3:** the root `LICENSE` file is now **required** and MUST be a **symbolic link** to the project's primary license text in `LICENSES/` (e.g. `ln -s LICENSES/GPL-3.0-or-later.txt LICENSE`), upgrading the former "a root `LICENSE` MAY remain as a GitHub-detection pointer" allowance. GitHub reads a repository's license from a root `LICENSE` file while REUSE requires the verbatim texts under `LICENSES/`; the symlink satisfies both from one source of truth — Git stores it as mode `120000`, GitHub follows it for detection, and `reuse lint` stays clean. A duplicated regular-file `LICENSE` is **non-compliant**: the two copies drift, and a stale root `LICENSE` misreports the project's license to every GitHub visitor. The link target is the repository's **primary** license per §4.1.1 — `GPL-3.0-or-later` (or `AGPL-3.0-or-later` when network-facing) for a software-primary repo, `CC-BY-SA-4.0` for a document-primary repo. **§5.2:** `LICENSE` added as a required posture file in its own right, alongside `README.md`, `NOTICE.md`, `CONTRIBUTING.md`, and `LICENSES/`. **§16:** compliance-checklist §4.3 bullet extended with the symlink requirement.
