Two framework promises were honour-system only, with no gate able to catch
a regression against either:
1. "Every visual value is a named token; hardcoded numbers are treated as
bugs" — a literal #3b5bdb in core/macros.css passes every existing check.
2. "Standalone, no external requests" — an absolute URL reaching a dist
bundle would make every consumer page phone home, silently.
The existing check:* gates all answer "is X in sync with Y?"; neither of the
above is a sync question, so nothing covered them.
Adds a rule-driven scanner over the source tree and the built bundles:
- hardcoded-color: hex / rgb() / hsl() literals in core/ + optional/ CSS,
excluding the four token source files whose job is to declare raw values.
Comments are masked with scripts/lib/parse.js's offset-preserving
maskComments, so issue references (#496, #497) are not false positives
and reported line numbers still point at the original source.
- external-url: any absolute URL in dist/*.css.
- debug-statement: console.log/debug and debugger in configurator/src.
scripts/ is out of scope — those are CLIs whose console.log is output.
Deliberate exceptions live in ALLOW, keyed by rule id -> file -> the exact
matched text (not merely the path), so excepting `#fff` in core/base.css does
not blanket-approve a future literal in that same file. Each entry carries a
reason, matching the docs/ref-allowlist.json contract.
Runs in the artifacts-freshness job after check-artifacts.js, which rebuilds
dist/ — so the bundle rules have something to scan.
13 negative tests assert each rule bites, that comment masking neither hides a
real violation nor mis-reports its line, and that an unbuilt tree does not
crash the gate.

…face block The 0.7.25 rename of --sf-color-text--secondary to --sf-color-text--subtle was applied in core/tokens.css but missed one mirror: the .sf-card block in optional/components.css, which re-derives the resolved colour tokens for a card sitting on an active surface, still declared the pre-rename name. The two declarations are character-for-character the same light-dark()/oklch formula, and that block's own comment (SL-001) states it mirrors tokens.css's "Resolved color tokens" — so this was a missed spot, not a deliberate divergence. Effect: nothing reads var(--sf-color-text--secondary), so the card was setting a name no one consumes while consumers reading the live --sf-color-text--subtle inside a card on a coloured surface silently got the unadjusted :root value instead of the card-tuned one. token-registry.json already had the old name flagged removed; only the stale declaration kept it textually alive. No catalogue or doc churn: a full rebuild regenerates every artifact byte for byte, because the declaration sat inside a @container style() block the API index never catalogued. Found by the new check:token-renames gate, which refuses to migrate users away from a token that is still live.

The configurator could persist an override set two ways, and neither is a file you can put in a repository: localStorage (trapped in one browser profile) and the share link (a compressed base64url blob — ideal for a short URL, opaque in a diff, and keyed by numeric token id). Adds a third form: *.slashed-theme.json, a name-keyed, sorted, pretty-printed snapshot. Because it is keyed by name and byte-stable, `git diff` shows exactly which token changed value — so a rebrand becomes reviewable in a pull request, and a theme can live next to the CSS it themes. Name-keying is what makes it readable and also what makes it vulnerable to a rename, so the format ships with a migration path: docs/token-renames.json — a curated mirror of docs/migration.md, seeded with the 45 renames and 31 removals that release actually documents. This cannot be generated: token-registry.json keeps ids permanent, but check-token-registry.js deliberately permits renames as in-place name updates on the same id, so after a rename the old name is simply gone with nothing to look it up by. Harmless for the id-keyed codec, fatal for a name-keyed file. A rename and a delete+add pair are also indistinguishable to a generator. scripts/check-token-renames.js — CI gate holding the map to three invariants: every rename target is live, no old name is still live, renames and removals are disjoint. Requiring targets to be live forbids chains by construction. It found a real bug on its first run (fixed in the preceding commit). scripts/migrate-theme.js — CLI. Report-only by default and exits non-zero when migration is needed, so it doubles as a CI check over committed theme files; --write is the explicit opt-in to mutate. Never discards an override it does not recognise: unknown names are reported and kept, because absence of knowledge is not evidence the user was wrong. Configurator gets export + import in the Setup panel, applying the same migration on load and listing every adjustment made. Its implementation is a deliberate mirror rather than a shared import: the @framework-css alias is remapped by the WordPress plugin to a vendored dist/ with no scripts/, so reaching across the package boundary at runtime would break that build. The mirror is held honest by configurator/tests/themeFile.test.ts, which runs both implementations over the same fixtures under Vitest (which, unlike the shipped bundle, can import both) and asserts identical results. 32 new tests: format validation, migration semantics (idempotence, collision handling, unknown-token preservation), round-trip byte stability, CLI exit codes, and 10 negative tests per gate invariant.

Greptile SummaryAdds portable JSON theme import/export, token-name migration support, and CI validation for rename metadata and forbidden shipped strings.
Confidence Score: 4/5The empty-value import defect should be fixed before merging because a valid theme file can apply unusable token overrides; terminal output escaping is also advisable. Theme validation currently turns whitespace-only values into active empty overrides that flow into preview and exported CSS, while collision reporting can emit theme-controlled terminal sequences. Files Needing Attention: configurator/src/lib/themeFile.ts, scripts/lib/theme-file.js, scripts/migrate-theme.js

| Filename | Overview |
|---|---|
| configurator/src/lib/themeFile.ts | Adds browser-side theme parsing, validation, migration, and serialization; whitespace-only values remain accepted as empty overrides. |
| configurator/src/components/panels/ExportPanel.svelte | Adds theme download/import UI and applies successfully migrated snapshots using the established replacement callback. |
| scripts/lib/theme-file.js | Defines the Node theme-file contract and migration behavior, mirroring the browser implementation but permitting empty and control-character values. |
| scripts/migrate-theme.js | Adds report and in-place migration modes; collision output exposes unescaped file-controlled values to the terminal. |
| scripts/check-token-renames.js | Validates rename targets, old-name liveness, malformed entries, chains, and overlap with removals. |
| scripts/check-forbidden-strings.js | Adds scoped source and bundle scanning with explicit exact-match allowances. |
| docs/token-renames.json | Adds the curated historical rename and removal registry consumed by both migration implementations. |
| optional/components.css | Completes the documented secondary-to-subtle token rename in the optional component declarations. |

When a theme contains an empty or whitespace-only value, validation trims and accepts it as an active override, causing the live preview and exported CSS to emit an empty custom-property declaration instead of retaining a usable token value.

A crafted theme containing both a legacy token and its current target can place ANSI or OSC control bytes in the retained value, which this collision message writes directly to a control-sequence-capable terminal. Escape non-printable bytes before including file-controlled values in CLI output. How this was verified: The retained value passes validation unchanged into the collision report and is interpolated directly into terminal output.

- Around line 93-103: Update the external-url pattern in the forbidden-string
check to detect protocol-relative references such as //host/path and match
HTTP(S) schemes case-insensitively, while preserving existing CSS URL detection.
Add a fixture covering a protocol-relative CSS `@import`.
- Around line 83-86: Update the color detection pattern in the forbidden-string
check to flag direct hwb(), lab(), lch(), oklab(), oklch(), and color() literals
while continuing to allow derivation forms such as oklch(from ...) and
oklch(var(...)). Add positive coverage for each newly detected function and
regression coverage for the permitted derivations and token values in
optional/customize-example.css.
In `@scripts/check-token-renames.js`:
- Around line 53-54: Reject arrays and other non-object values for the root
token-rename map and each present renames/removals section before iterating or
returning migration maps. Update check-token-renames.js and migrate-theme.js
accordingly; add failing fixtures in tests/check-token-renames.test.js for [],
{"renames":[]} and {"removals":[]}, covering the affected ranges.
In `@scripts/lib/theme-file.js`:
- Around line 168-179: Update scripts/lib/theme-file.js:168-179 and
configurator/src/lib/themeFile.ts:146-154 to detect when a deprecated alias
target already exists in out, retain the established deterministic value, and
append a collision record instead of overwriting it; extend
tests/theme-file.test.js:129-138 with two deprecated names resolving to one
target and assert the collision report and retained value.

All four review findings reproduced; each is fixed with a regression test. Theme-file validation (both implementations): - An empty or whitespace-only value was trimmed and kept as an active override, so generateCSS() emitted `--sf-x: ;` — a broken declaration shadowing the real token with nothing. codec.ts already drops empty values on encode and decode; a file is now told rather than silently fixed. - Values and the theme name accepted control characters. JSON forbids them as literal bytes but the escape form is legal, so a crafted file could carry an ESC into the migration CLI's output, which a terminal interprets. Rejected at validation — the single choke point — with escaping in the CLI as a second layer, since migrateOverrides() is exported. - Whitespace is now collapsed the way codec.ts's sanitizeValue() does it BEFORE the control-character test, so a multi-line box-shadow value normalises instead of being rejected, and the two paths cannot disagree about what a value means. Migration: - Two different old names can resolve to the same live token, and the map already contains such pairs (--sf-color-danger-light and --sf-color-error-source-light both land on --sf-color-danger-source-light). The second assignment overwrote the first with no collision record — the exact silent data loss migrateOverrides() documents as impossible. Sorted iteration makes first-claim-wins deterministic; the loser is now reported. Gates: - check:forbidden-strings missed direct modern colour literals. Now flags hwb/lab/lch/oklab/oklch/color() while exempting oklch(from …) and oklch(var(…)) — those are the derivation syntax the token layer is built on, not hardcoded values. optional/customize-example.css is excluded: it ships in no bundle and literal brand colours are its entire purpose. (The reviewer cited optional/utilities.css:263, which is inside a comment block for a staged utility — correctly not flagged, before or after.) - The external-url rule ignored protocol-relative //host/path references, which CSS accepts in @import and the browser fetches using the page scheme. Verified the widened pattern produces no new matches on the real bundles. - docs/token-renames.json accepted an array at the root or in either section. An array yields no entries, so every downstream check passed vacuously and the CLI silently migrated nothing. Both the gate and the CLI now refuse it.

Summary
Adds a portable, reviewable theme file format (
*.slashed-theme.json) for persisting token overrides. Theme files are name-keyed, sorted, and pretty-printed sogit diffshows exactly which tokens changed — making them suitable for committing alongside CSS and reviewing in pull requests.Includes:
