docs: rename Cube.js to Cube across the repo

[ovr]

The product has been called Cube since v0.29, but "Cube.js" still survived in 174 files — READMEs, package.json descriptions, CLI and server output, doc comments and the issue template — so this renames the brand everywhere it appears as prose, leaving the cube.js filename and the cubejs/cube-js identifiers alone. Three spots needed more than a substitution: packages/cubejs-api-gateway/openspec.yml holds the OpenAPI title that openapi-generator stamps into every rust/cubesql/cubeclient/src/models/*.rs header (spec and generated files updated together, so a regeneration stays a no-op), DEPRECATION.md's "Embedding Cube.js within Express" heading changes its slug so both inbound anchors are retargeted, and two pre-existing casualties of an earlier rename pass are repaired — CONTRIBUTING.md's "Cube.is written in a mixture of JavaScript..." and DCO.md's "make it easier for everyone to Cube.js, and we are adopting a DCO". Deliberately untouched: fileName: 'MockUsersCube.js' in the api-gateway meta test (a filename, not the brand) and the CHANGELOG.md files (a historical record).

Check List

• Tests have been run in packages where changes have been made if available
• Linter has been run for changed code
• Tests for the changes have been added if not covered yet
• Docs have been added / updated if required

Verification: root tsc --build is green, oxlint reports 0 errors over the changed sources, and the packages whose runtime strings changed pass their unit suites (cubejs-api-gateway 11/11, cubejs-server-core 44/44).

Review: approve with one nit — 0 high, 0 medium, 3 low

Full review

• Gather PR context and diff (174 files in the commit; the PR header's "100 changed files" is GitHub truncation)
• Review renames for identifier / URL / anchor breakage
• Check openspec.yml ↔ generated Rust model headers
• Check DEPRECATION.md anchor retargeting
• Verify no stragglers outside the declared exclusions
• Post review

Verification performed

Check	Result
Remaining Cube.js outside CHANGELOG.md	only MockUsersCube.js in transform-meta-extended.test.ts — the declared exclusion ✅
#embedding-cubejs-within-express referrers repo-wide	0 remaining; both inbound links retargeted to #embedding-cube-within-express ✅
openspec.yml info.title/description vs cubeclient/src/models/*.rs headers	in sync; a regeneration stays a no-op ✅
cubeclient/src/apis/*.rs	headers already stripped upstream, nothing to update ✅
Identifiers / URLs / package names	untouched — cubejs, @cubejs-backend/*, cube.js filenames, github.com/cube-js/cube.js links all preserved ✅

Every runtime-string change I read is prose-only: CLI warnings (sql-server.ts, cli.ts, node-check.ts), the production-mode HTML in server.ts, the shutdown log field in server.ts, JSDoc in the React/core clients, and Rust comments in wrapper.rs/filters.rs. None is parsed, matched on, or snapshot-asserted anywhere.

Findings (all low)

1. packages/cubejs-server-core/test/unit/index.test.ts:741,762 — the only semantic regression I found: // Cube.js can override env labelled a block of cube.js config file options (// cube.js marker below it, testName: '… from cube.js'). The renamed comment now reads as a claim about the product and loses the config-vs-env contrast. Inline comment with a suggestion posted.
2. packages/cubejs-client-react/src/types.ts:89 — generated by \Cube`in backticks. The code formatting made sense when the token wasCube.js-as-package; a bare backticked Cubenow reads like an identifier. Dropping the backticks would be cleaner, but this ships into the published.d.ts` so it's cosmetic either way.
3. .github/ISSUE_TEMPLATE/question.md:13,19 — **Related Cube schema** is a faithful rename, but "schema" is itself legacy terminology; "data model" is the current name. Out of scope for a brand rename, just noting it for a follow-up.

Notes, not objections

• manifest.json short_name/name changes the Playground's PWA install label — intended and consistent with the rest.
• Cargo.toml / package.json description edits are published metadata; they land on the next release with no version bump needed.
• The DCO.md and CONTRIBUTING.md repairs ("everyone to Cube.js" → "everyone to contribute to Cube", "Cube.is written" → "Cube is written") fix genuine pre-existing breakage from an earlier pass — good catch, and worth calling out since they're the only non-mechanical prose edits in the diff.

No security, performance, or test-coverage concerns: the diff touches no control flow, no query construction, and no auth logic. No new tests are warranted for a prose rename; the existing cubejs-api-gateway and cubejs-server-core suites already cover the files whose strings moved.

No prior review threads existed on this PR, so nothing to resolve or deduplicate against.

Re-review after eea948a: approve — 0 high, 0 medium, 1 low (the sibling line the fix missed)

Full review

• Inspect new commit (eea948a, 1 file / 1 line)
• Re-run verification sweeps (stragglers, anchors, openspec ↔ generated headers)
• Check prior review threads
• Post review

What changed since the last round

eea948a applies my suggestion at packages/cubejs-server-core/test/unit/index.test.ts:741 — // Cube can override env → // cube.js config can override env. Correct fix; the config-vs-env contrast is restored.

Re-verification

Check	Result
Remaining Cube.js outside CHANGELOG.md	only MockUsersCube.js in transform-meta-extended.test.ts — the declared exclusion ✅
#embedding-cubejs-within-express referrers	0 remaining; DEPRECATION.md:41 and :195 both point at #embedding-cube-within-express ✅
openspec.yml info.title/description vs cubeclient/src/models/*.rs headers	title: "Cube" / "Cube Swagger Schema" matches the generated headers — regeneration stays a no-op ✅
Identifiers / URLs / package names	still untouched (cubejs, @cubejs-backend/*, cube.js filenames) ✅

Finding (low)

1. packages/cubejs-server-core/test/unit/index.test.ts:762 — the same comment appears twice; eea948a fixed 741 but not 762, so the file is now internally inconsistent (// cube.js config can override env at 741, // Cube can override env at 762). Inline suggestion posted. Cosmetic — no test behaviour depends on it.

The prior thread on 741 is resolved/outdated, so nothing stale to clean up. My two other low notes from the last round (client-react/src/types.ts:89 backticked Cube, question.md "schema" vs "data model") were cosmetic/out-of-scope and I'm not re-raising them.

Finding (low)

1. examples/recipes/passing-dynamic-parameters-in-query/.env:1 — # Cube.js environment variables: https://cube.dev/docs/reference/environment-variables. A tracked file with the brand in prose that the sweep missed (my earlier rounds' straggler grep didn't reach dotfiles — my miss, not a regression from 8812085). It's outside the diff so I can't attach an inline comment; a one-line follow-up would close the sweep. Fix this →

The only other remaining hit is fileName: 'MockUsersCube.js' in packages/cubejs-api-gateway/test/helpers/transform-meta-extended.test.ts — the declared, correct exclusion (a filename, not the brand).

Threads

Both of my prior inline threads on index.test.ts are resolved and outdated; nothing stale to clean up. The two cosmetic notes from round one (client-react/src/types.ts:89 backticked `Cube`, question.md "schema" vs "data model") remain out-of-scope for a brand rename and I'm not re-raising them.

Re-review after force-push to 12c01e5: approve with one regression to re-apply — 0 high, 1 medium, 2 low

Full review

• Inspect the squashed commit
• Confirm earlier review fixes survived the squash
• Re-run verification sweeps (stragglers, anchors, openspec ↔ generated headers)
• Check / resolve prior review threads

What changed since the last round

The branch was rewritten: the three commits I reviewed previously (88120… and parents) are gone, replaced by a single squashed 12c01e5 with the same 174-file / 397-line shape. Content is otherwise unchanged — except that the squash did not carry the two comment fixes from eea948a and 8812085.

Remaining Cube.js outside CHANGELOG.md	2 hits — one declared exclusion, one straggler (finding 3)
Brand variants the Cube.js pattern missed (Cube.JS, CubeJS)	1 in-diff hit (finding 2) + Rust comments, see notes

Findings

1. Medium — packages/cubejs-server-core/test/unit/index.test.ts:741,762: the squash lost the accepted fix. Both comments read // Cube can override env again, but the Cube.js they came from was the config file, not the brand — the block each labels is // cube.js options with testName: 'Override … from cube.js', so the contrast is config-file-vs-env. As written they read as a claim about the product. Inline suggestion posted (both prior threads are marked resolved/outdated, so I re-raised rather than replying). Comment-only; no test behaviour depends on it.

2. Low — rust/cubesql/cubeclient/README.md:13: > API client for Cube.JS powered on Rust language. Capital JS, so the sweep's Cube.js pattern skipped it — but it sits two lines from an edited line in the same hunk, alongside the alt="Cube" and "Cube Open API Specificiation" renames. Inline suggestion posted.

3. Low — examples/recipes/passing-dynamic-parameters-in-query/.env:1: # Cube.js environment variables: …. Still the one tracked-file straggler in prose; outside the diff so no inline comment possible. Fix this →

Notes, not objections

• fileName: 'MockUsersCube.js' in packages/cubejs-api-gateway/test/helpers/transform-meta-extended.test.ts:112 remains the correct declared exclusion — a filename, not the brand.
• CubeJS survives in three Rust comments (cubestore/src/cluster/message.rs:142, cubestore/src/sql/mod.rs:1600, cubestore-sql-tests/src/tests.rs:4847) referring to the Node.js side of the system. Arguably the brand, but outside this PR's declared Cube.js scope and none are in the diff — mentioning only so the next sweep knows they're there.
• .github/workflows/push.yml:720 ("Testing CubeJS (container mode)") can't be edited by this app anyway (workflow permissions).
• Everything else I read is prose-only and unparsed: CLI warnings, the production-mode HTML and shutdown log field in server.ts, client JSDoc, manifest.json PWA labels, Cargo.toml/package.json descriptions. No control flow, query construction, or auth logic is touched; no security, performance, or coverage concerns, and no new tests are warranted for a brand rename.

Threads

Both of my prior index.test.ts threads are already resolved and outdated (the lines they anchored to no longer exist after the rewrite), so nothing stale to clean up.
