feat(palette): Steelbore Hanzo Steel (§11.3.6) — v2.05 - #71
Conversation
Adds a tenth palette to the §11 family, inspired by the Kill Bill Vol. 1 poster. Anchored on Sumi Black (#000000) and Hanzo Gold (#FCD612) — the family's first pure-black canvas. The source sheet's Venetian Red measures 4.03:1 on black, below the 4.5:1 text floor, so it ships deepened as Crimson Edge (#F04A44) — the same move §11.3.4 NavyWhite makes for its status hues. The result is a palette with zero restricted pairings: every foreground token clears 4.5:1 on all three backgrounds, weakest 4.85:1 (error on surface). The high-contrast sibling lifts `error` alone, to the family's shared Ember Lift. Mint Signal and Ember Lift are carried at their existing values rather than redefined: the palette-css gate resolves token names across the whole file, so a name bound to two hexes would shadow another palette's check. Counts updated throughout — ten palettes, 19 themes, fifteen in the §11.6.1 registered set. Also corrects two pre-existing enumerations that Tokyo Night had already made stale: the palette skill's "Four alternates" (now six) and the accessibility skill's palette list, which omitted tokyonight. All 266 contrast ratios across all 19 themes re-derived from their hexes with the WCAG 2.2 relative-luminance formula: zero mismatches. steelbore.scm regenerated; not hand-edited.

Skill-side sync of the Standard's v2.05. §11's full text lives in references/palettes.md since the split, so the new §11.3.6 subsection, the family table row, the §11.4.1 reference name, and the §11.6.1 arithmetic (thirteen -> fifteen, adds ten -> adds twelve) all land there. SKILL.md carries the masthead bump, the palette count in its §11 summary, the opt-in list, and the §16 checklist line. The frontmatter description is untouched: §11's palette enumeration moved to references/palettes.md, so the description never named the palettes. Values themselves are not restated here — they live in steelbore-color-palette/assets/steelbore.toml, which §11.4 makes the single source. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The commit modifies five root skill trees—spacecraft-accessibility-support, spacecraft-brand-guidelines, spacecraft-steelbore-standard, spacecraft-theme-factory, and steelbore-color-palette—but both .zip and .skill for every one retain their parent blob IDs. Consequently, bundle installations omit the new palette and retain the old Standard and theme metadata; rebuild and commit all ten matching bundles.

When this line advances the Standard to v2.05, the loader-facing frontmatter description at line 11 still says that the skill encodes v2.04. Agents and catalogues that inspect the description therefore receive contradictory release metadata even after loading the corrected source; update that version alongside the masthead.

Adds the tenth palette to the §11 family and syncs the skill encoding. Two commits:
feat(palette)— the canonical values insteelbore.toml, plus every enumeration that goes stalefeat(spacecraft-steelbore-standard)— the skill-side sync of the Standard's §11.3.6Pairs with Spacecraft-Software/Standard#39 at the same version and date.

steelbore-hanzosteel-high-contrastliftserroralone, to Ember Lift (9.58:1).Two things worth reviewing closely
The red is deepened, not verbatim. The source measures 4.03:1 on black and 3.39:1 on the surface. §11.3.4 sets the precedent for deepening a source hue to reach AA; a conforming alternate is not a §11.5 fidelity palette. The rationale is written into the section rather than left implicit.
Token names are a shared global namespace.
check-palette-css.pyresolves names across the whole file first-writer-wins, so a name bound to two different hexes silently shadows another palette's check. All eight new names were verified free against the existing 107, andMint Signal/Ember Liftare carried at their existing values rather than redefined.Counts, and two pre-existing errors fixed in passing
Ten palettes, 19 themes, eight conforming, fifteen in the §11.6.1 registered set — updated in
steelbore.toml, both changelogs,README.md, and five skills.Tokyo Night had already made two enumerations stale before this change; both are corrected here rather than left:
steelbore-color-palette/SKILL.mdsaid "Four alternates" (it was five, now six)spacecraft-accessibility-support— SKILL.md andreferences/audit.mdboth omittedtokyonightfrom the declarable-palette list, and audit.md said "all six"Not touched
assets/spacecraft.css— it declares Steelbore Modern tokens only and is the HTML theme for the Standard's own output. All copies remain byte-identical.Verification
