• planning: execute and resume plan sequences (8407187)
• planning: validate semantic plan composition (3903bbf)
• starbases: add player registration planner (778daef)

BREAKING CHANGES

• the package publishes as @aephia/atlas-kit; every public module specifier moves from @aephia/sage/* to @aephia/atlas-kit/*. No compatibility shim: nothing depends on @aephia/sage yet. ATMTA's CEO did not approve "Star Atlas Kit"; the approved product name is "Atlas Kit" and the full "Star Atlas" mark must not appear in the product name (D051).

The GitHub repository is renamed Aephia/sage-sdk -> Aephia/atlas-kit in the same motion, because npm trusted publishing matches the repo name exactly. The distributable agent skill renames to aephia-atlas-kit (user-facing). The unpublished D050 plan-sequence fingerprint domain renames to aephia-atlas-kit/plan-sequence- fingerprint/1 (length prefix 39 -> 44, goldens updated).

Kept deliberately: Sage-vocabulary API names (createSageClient, SageContext, ...) — "Sage" denotes the game's SAGE C4 program, not the product — plus the internal packages/sage directory and the private @aephia/sage-docs app. llms.txt / llms-full.txt regenerated.

• feat: rename the docs app and site to atlas-kit-docs

The documentation site is user-facing, so it follows the product: @aephia/sage-docs -> @aephia/atlas-kit-docs (workspace filters, CI, scripts), aephia-sage-docs.pages.dev -> atlas-kit-docs.pages.dev (PRODUCTION_URL, generate-llms SITE_URL, skill and ai.md links, regenerated llms artifacts), and the playground storage key. The sage-dev-docs.pages.dev C4 bindings site keeps its name: it documents the game's SAGE program, not the product.

The Pages project itself is git-integrated and must be recreated in the Cloudflare dashboard as atlas-kit-docs; apps/docs/README.md documents every setting.

• docs: retitle the product to Atlas Kit everywhere readers see it

The mechanical rename missed the human-readable title: llms.txt/ llms-full.txt headers, the docs site chrome and landing frontmatter, the agent skill's H1, README/AGENTS/ARCHITECTURE/TEST_PLAN titles, and the SDK map's accessible title all still said "Aephia SAGE SDK" or "SAGE SDK". All now say Atlas Kit; llms artifacts regenerated.

• fix(fleets)!: purge "sector" from the translated surface (#275) (41fbb31)

Bug Fixes

• release: keep a breaking change on the minor while the SDK is 0.x (#278) (341b3d2)

BREAKING CHANGES

• SectorCoordinates is removed in favour of WorldCoordinates, and the idle Fleet state exposes coordinates instead of sector. WorldCoordinates is re-exported from @aephia/sage/fleets, so a caller importing only the Fleet surface still has the type.

"Sector" is pre-C4 vocabulary from SAGE Starbased, whose map was a 101x101 grid of discrete sectors. C4 has no grid: positions are floating-point coordinates decoded from fixed-point pairs, and a sector is not something a caller can hold, compare, or move between.

The correction removed a duplicate rather than renaming one. SectorCoordinates and WorldCoordinates were structurally identical and decoded identically, so they named one coordinate space twice. A third name such as MapCoordinates was rejected because it would have preserved the duplication under new vocabulary.

No compatibility alias, on the maker-ATLAS precedent. Only @aephia/sage/bindings keeps the generated names. D046 additionally binds surfaces that have not landed yet: the IDL's sectorWinDelta, sectorIncumbent, and their neighbours must be translated to non-sector names rather than mirrored.
