Fix: keep URL basic-auth credentials on the scan origin (#657)

page.authenticate is page-wide, so a cross-origin redirect that then 401s would receive the original credentials. Attach Authorization only to requests for the scan origin.

 ## Setup
 
-1. Run `<skill-base-dir>/scripts/impeccable context` once per session, where `<skill-base-dir>` is the directory that contains this SKILL.md (the skill folder, not a plugin root two levels above it); keep cwd at the user's project. That base directory resolves every `.agent/skills/impeccable/scripts/impeccable <verb>` command in this skill and its references, and `.agent/skills/impeccable/scripts` is the fallback only when the runtime reports no base directory. On a Windows shell without `sh`, call `.agent/skills/impeccable/scripts/impeccable.cmd` instead. The launcher runs a self-contained binary that ships next to it or is downloaded once on first run; no Node or other runtime is required. Pass a named source file or route as `--target <path>`. It loads PRODUCT.md, DESIGN.md, the matching surface brief, and native-platform guidance when applicable; follow its directives and do not rerun it. If the launcher is refused, missing, or fails, tell the user before editing that context loading did not run. Read existing **PRODUCT.md** and **DESIGN.md** without inventing missing context, then continue with steps 2–3.
-2. Load the request's playbook: its Commands-table reference for an explicit/implied sub-command, or [reference/new-work.md](reference/new-work.md) for a new surface or replacement visual world. Inspect target and incumbent visual truth before editing. When the app cannot run, start with committed visual-regression goldens or screenshot fixtures; verify target and freshness against current tokens, CSS, components, or assets, resolve conflicts, and compare theme/variant captures.

Then inspect the target and at least one representative source of incumbent visual truth (tokens, theme, CSS, component, or asset) before editing.
 3. After analysis and direction are resolved, load [reference/craft-floor.md](reference/craft-floor.md) immediately before editing UI. It carries the quality floor, the absolute bans, and the reflexes no detector catches. Do not load it for planning-only work.

 ## Input Contract
 
-Expect the measured spec (`.impeccable/build/spec.json`, written by `impeccable comp-spec` from the approved comp), the approved comp path, and the skill scripts path. Optionally: a subset of region ids to produce, extra prompt notes per region, and format or transparency needs. Everything else you need is in the spec: each raster region's id, kind (plate, image, texture), pixel box, sampled palette, aspect, note, and the plate path it must land on.
+Expect:
 
-If there is no spec, stop and return one line asking the parent to run `impeccable comp-spec` first. You do not inventory the comp yourself; the spec is the inventory, and a second inventory disagrees with the first.
+- Approved mock path or screenshot reference.
+- Crop paths or a contact sheet with crop ids.
+- Output directory.
+- Required dimensions, format, transparency needs, and avoid list.
+- Notes on what should remain semantic HTML/CSS/SVG instead of raster.
 
-## The job
+If the source mock is attached but has no filesystem path, use it for visual planning; ask for a path only before cropping or writing assets.
 
-Every region with `medium: raster` in the spec ships as a plate at its `plate` path. A plate is the region regenerated at asset resolution from the comp crop as reference: same subject, same composition, same palette, same lighting and material, with the UI text and page chrome removed, at 1.5x the comp region's pixel size or more. The page draws text, controls, radius, shadow, and layout in code; the plate carries what code cannot draw. Crops from the comp are references, never shipping pixels: a comp is reference grade and a shipped crop is how a beautiful comp becomes a blurry site.
+Defaults unless contradicted:
 
-Per region, in the spec's order:
+- `.webp` for opaque photos, backgrounds, and textures.
+- `.png` for transparent cutouts, seals, tickets, and illustrations.
+- Target production size, or at least 2x display size when dimensions are known. Never default to the small size of a full-page mock crop.
+- Remove UI text, navigation, buttons, labels, and body copy.
+- Keep physical marks only when the parent says they are part of the asset.
+- Remove letterboxing, empty padding, baked card corners, borders, shadows, caption bands, and layout background unless the parent says those pixels are intrinsic.
+- Keep the final assets directory clean: only files the build will consume. Source crops, reference crops, masks, and contact sheets go in a sibling `_sources`, `sources`, or review folder.
 
-1. `.agent/skills/impeccable/scripts/impeccable comp-spec --crop <id>` writes the reference crop under `.impeccable/build/crops/`.
-2. Produce the plate. With the API fallback: `.agent/skills/impeccable/scripts/impeccable generate-image --plate <id> --quality high` does the whole step (crop as reference, the spec's plate prompt, output size chosen from the region's aspect, the file written to its plate path, prompt embedded, and the plate scored against the crop). With a harness-native image tool: use the crop as the input image and `.agent/skills/impeccable/scripts/impeccable comp-spec --plate-prompt <id>` as the prompt, write the result to the plate path, then run `.agent/skills/impeccable/scripts/impeccable embed-prompt <plate> --prompt "<the exact prompt>"`.
-3. Read the score line. `PLATE-SCORE` under 50%, or a `PLATE-WARN`, means the plate does not read as the region: open the plate beside the crop, name what drifted (subject, framing, palette, style), tighten the prompt with that, and regenerate once. Two misses on one region: keep the better plate, mark it `needs_parent_review`, and say why in one line.
-4. Transparent cutouts (a figure or object on the page ground): generate on a flat chroma color absent from the subject and key it to alpha before writing the PNG; never ship the keyed background.
+Ask blockers once, globally. Missing source path/crops or output directory blocks production. Exact dimensions, compression targets, retina variants, and format preferences do not; choose defaults and report them.
 
-Do not redesign. Do not add objects, restyle, or reinterpret; the comp was approved as it is. Do not touch the page code, the spec, or the comp. Do not produce anything the spec does not list; a region the parent forgot goes back as a one-line note, not a plate.
+## Workflow
+
+1. Inventory the full approved mock or every assigned crop.
+2. Put each visual role in exactly one bucket:
+   - `produce`: needs generation, image editing, cleanup, cutout work, or a clean plate before it can ship.
+   - `direct`: ships after format conversion, compression, or renaming because the parent supplied a real standalone source: a project file, stock, or prior production art. A crop from the approved mock is never `direct`, whatever its apparent size.
+   - `semantic`: build in HTML/CSS/SVG/canvas, no raster output.
+3. Crops from the mock are binding visual references, never shipping pixels: a full-page mock's effective resolution is reference grade, and a shipped crop, however close it looks, is how a beautiful comp becomes a blurry site. Every mock-derived asset goes through `produce` as a clean regeneration.
+4. Give the parent an execution order for the `produce` bucket.
+5. For produced assets, choose the least inventive strategy: image-to-image clean plate, faithful regeneration from crop reference, transparent cutout, texture/pattern reconstruction, stock/project source, or a semantic HTML/CSS/SVG recommendation when raster is wrong.
+6. Use the harness's native image tool by default when generation or editing is needed; otherwise use the skill's generate-image.mjs.
+
+7. Remove baked-in UI text, navigation, buttons, body copy, and mock chrome unless the text is part of the asset.
+8. Think through the final DOM/CSS representation before generating. If CSS will own radius, clipping, shadows, borders, perspective, responsive cropping, captions, or card frames, do not bake those into the bitmap.
+9. Save outputs non-destructively in the requested project directory, and leave the intent with the file: after every generation, run `node .agent/skills/impeccable/scripts/embed-prompt.mjs <asset> --prompt "<the prompt used>"` so the prompt lives inside the image itself. The build thread composes what you made and needs to know what it is looking at, and the embedding survives copies where sidecars get lost.
+10. Compare each output against its source crop, opening every image by its workspace-relative path; sandboxed viewers reject absolute paths. If a review/QA tool is available, run it before the final manifest, then retry each major/fatal finding once before finalizing.
+
+Use `texture/pattern extraction` only when the source region is already clean enough to sample as texture. If UI, cards, labels, headings, body copy, or footer chrome must be removed first, classify it as crop-derived cleanup or clean-plate work.
+
+Use `semantic` for dashboards, charts, controls, screenshots of whole UI sections, data widgets, card chrome, app frames, icon toolbars, logos, wordmarks, and anything the final implementation can render crisply in HTML/CSS/SVG/canvas. Ship a screenshot raster only when the parent explicitly says the screenshot itself is the final asset.
+
+Semantic does not mean ignored. For every semantic role, write a concrete implementation handoff for the parent craft agent: the DOM/component layers, CSS-owned visual treatment, SVG/canvas/icon-library pieces, responsive behavior, and which nearby produced raster assets it composes with. For logos and icons, prefer inline SVG/vector or icon-library implementation unless the parent provides a production logo raster.
+
+## Prompt Pattern
+
+Use this shape for image-to-image work:
+
+```text
+Use the provided crop as the approved visual reference.
+Recreate the same asset as a clean reusable production image at the target component aspect ratio and at least 2x display resolution.
+Preserve silhouette, object/scene perspective, camera angle, palette, lighting, material, texture, and visual role.
+Remove baked-in UI copy, navigation, buttons, labels, body text, watermarks, and mock chrome unless explicitly part of the asset.
+Remove letterboxing, padding, card borders, rounded clipping, CSS shadows, perspective transforms, caption bands, and layout backgrounds that the implementation should create in code.
+Do not add new objects. Do not change the concept. Do not redesign the composition.
+```
+
+For transparent cutouts: use true alpha when the tool supports it; otherwise generate on a flat chroma-key color that cannot appear in the subject and post-process that color to alpha before shipping the PNG/WebP. Never ship the keyed background as the final asset.

+Return a complete manifest, grouped by `produce`, `direct`, and `semantic`. For each asset include: `id`, `source_crop`, `output_path` when applicable, `strategy`, `prompt_used` when applicable, `dimensions`, `format`, `transparency`, `deviations`, and `qa_status`.
+
+For each semantic row include `id`, `implementation`, `notes`, and `qa_status`. The `implementation` is a concrete build handoff, not a note that no asset was produced: name the likely HTML/CSS/SVG/canvas/icon/component pieces and the visual responsibilities code owns.
+
+`qa_status` is `accepted`, `needs_parent_review`, or `blocked`. `accepted` only after visual comparison passes. `needs_parent_review` for cut-off subjects, unwanted borders or rounded-card chrome, letterboxing, baked semantic text, low-resolution output, perspective that should have been CSS, missing transparency, or drift from the crop. `blocked` when inputs, permissions, image capability, or asset source quality prevent a credible result.
+
+End with `execution_order`, `blockers`, and `assumptions` sections. Keep blockers global and minimal; per-asset rows carry only asset-specific risks or decisions.
+
+Do not modify implementation code. Do not edit the approved mock. Do not produce final page copy. The parent craft agent owns implementation and final mock fidelity.

 ## Checks, in order
 
 0. **Evidence.** Before any other check, verify the required captures exist and every capture is valid. Required: the platform's full viewport set (web: `desktop.png` and `mobile.png`; native: one capture per shipped device class), plus every capture the calling brief names as required, a reported user viewport (`user-<width>.png`) included. Valid: no black or blank regions, content matching what the filename claims (a visit capture showing the About section is invalid), the document top visible where the file claims a full page, dimensions that make sense for the named viewport. A required capture that is absent fails exactly like one that is malformed: a viewport nobody captured is a viewport nobody inspected, and it cannot ship. When any capture fails, the whole review changes shape: return `disposition: recapture` as the first line, then one section, `recapture`, listing each missing or invalid file and what a valid capture of it shows, and stop. Never build a matrix on malformed evidence; a verdict derived from a broken capture launders the breakage into an approval, and the parent owes you a full re-review on valid captures, not a scoring round.

On a comp-led build, `.impeccable/build/state.json` exists and its `comps` (or `skipped` when a surface round locked the comp), `spec`, `plates`, and `hero` phases are `closed`; a comp-led config with no state file, or a state whose `comps` phase never closed, means the comp round was skipped and the build ran from a world description alone, a material finding that outranks craft; a phase closed with a `forced` record is disclosed as a material finding unless the user downgraded the comp in words the packet quotes; a state file whose `hero.gate.score` sits under 0.72, or a missing state file, means the reproduction ran unproven, a material finding, and `.impeccable/review/hero-repro.png` must exist either way. When DESIGN.md predates this build (an extension or redesign), it matches the built world; on a new world it is written after this review by the documenter, so its absence here is not a finding. When comp-round comps exist under `.impeccable/mocks/`, an approval record exists too: the surface brief naming the approved comp, or an `approved` flag in its sidecar. Comp-round comps with no recorded pick mean the approval point was skipped, a material finding. Files under `.impeccable/mocks/decision/` are exempt: they are the direction round's dealt hand, produced before any comp round, and imply no approval whatever the build path; a code-led build has no comp round at all.
-2. **Fidelity.** Start from the measurement, then judge what it cannot: read `.impeccable/review/diff/final/report.json` (and hero) first; every region scored `missing` or `contradicted` is a matrix row in that state unless the paired crop under `regions/` shows the score is wrong, and you say why; a region scored `match` still gets your eye for lettering character and material, which the numbers do not measure. Then, against your own element inventory of the approved comp, never against the contract's summary of it: topology, reading order, focal scale, overlaps and z-order, density, signature geometry, the primary action's treatment (a CTA the comp physically works, dissolves, or stamps is a signature element; its plain-rectangle rendition is contradicted), navigation items and icons, headline levels and scale relationships. Classify every salient element: match, acceptable adaptation, missing, contradicted, or added without approval. Three rows are mandatory in every matrix. TYPE: the display lettering's character, compression, width, weight, contrast, terminals, against the comp's; a face of a different character is contradicted however the layout matches. MATERIAL: an element rendered as flat CSS or clean vector where the comp shows painted, textured, dimensional, or photographic material is contradicted regardless of placement; medium is part of the promise. GROUND: the page field's value and temperature against the comp's, sampled from pixels on both sides when tooling allows rather than judged from memory, and read as the net on-screen result where a texture or tile paints over the base color; a ground warmer or cooler than the comp's is contradicted however faithfully the layout matches, and drift toward the rendition prior (warm cream on light grounds, blue-black slate on dark) is the direction to hunt. With no approved comp, TYPE and MATERIAL do not lapse: judge them against the contract's OWN-WORLD and the world's real materials, and treat faked physicality (CSS bevels, embossing, stamped-metal or chalk effects imitating a material the page never renders) as contradicted on its face; imitation material is the single most reliable mark of machine-made design. GROUND narrows rather than lapses: with no comp to sample, a color OWN-WORLD names is the target and the same warmer-or-cooler judgment applies; when OWN-WORLD names none, there is no GROUND authority, and the review says so in place of a verdict, because a target the reviewer invents turns the check into taste. A critique-reference comp on such a build is provocation, not spec: no element matrix, no adaptation citations, no asset obligations; its one contribution is what the image dared that the build did not, and dares worth adopting enter material_fixes as ordinary ordered fixes. An adaptation counts as intentional only when it cites the user answer, surface brief, accessibility need, or product truth that forced it; an uncited deviation is a defect. A missing signature element, a changed topology, or content added without approval fails fidelity and outranks every craft point in material_fixes. When MATERIAL is contradicted on the focal element, or contradiction is the page rather than the exception, stop ordering repairs: make the first material fix a rebuild directive naming the comp regions to re-derive and the assets to produce; a list of patches against a rejected page launders the rejection into an approval. A fix that requires producing an asset says so explicitly ("produce: <region> as a raster asset"), never phrased as a style adjustment the parent will answer with CSS. The comp is the spec for composition, topology, element inventory, density, lettering character, and material; it is not a pixel spec for semantics, accessibility, or responsive reflow, and that allowance covers translation, never replacement.

 4. **Contract, promise by promise.** First verify FORM carries the seed key the concept roll printed; a contract with no seed key, or one the parent cannot corroborate, means the roll was skipped, a material fix ahead of any craft point.

-5. **Truth.** Demonstration data authored and labeled synthetic; no invented commercial claims; unanswered claims present as marked placeholders, not omissions.

 6. **Floor.** Read the craft floor's Refuse list and hold the screenshots against it: kickers and eyebrows, hard offset shadows outside a neobrutalist world, glyph icons, system display faces, gradient text, side stripes, and the rest. A banned element is a material fix even when it matches nothing in the comp: the builder loaded the same ban before writing it, and fidelity to a comp cannot authorize what the floor refuses. The parent's hook findings cover this mechanically where hooks run; this check exists because hookless harnesses reach you with none, and the last two live sessions shipped five kickers past a reviewer that never looked.

 - Cursor can block a proposed write when the detector finds a real issue. Claude Code, Codex, and GitHub Copilot do not block the edit; they emit a post-edit reminder instead. Disabling stops both blocking and reminders.
 - The hook is bundled with the Impeccable skill and installed through project-local manifests: `.claude/settings.local.json`, `.codex/hooks.json`, `.cursor/hooks.json`, and `.github/hooks/impeccable.json`. On Codex, the user must approve the hook via `/hooks` the first time. On Cursor, confirm hooks are enabled under Settings -> Hooks. On GitHub Copilot, the CLI loads `.github/hooks/impeccable.json` once it is committed to the repository's default branch, and the cloud agent reads it from the repo directly.

A recommendation you made is not an answer you received, and a value taken from silence is a standing default nobody set: it then rides every future round in the project, which is the opposite of asking once. When the question goes unanswered, record nothing and say in one line which path this session is taking and that it is not stored. That path is comp-first, the default new-work applies wherever image generation exists and nothing is recorded; name it rather than choosing a quieter one, because a silent default invented here is the same failure as a value written without an answer. Unset is a working state, not a gap: the decision page's toggle governs each session, and new-work's one-time offer records the answer the first time the user flips it.

Run directly with no preflight scaffold, it writes the wrapper itself and you splice variants at `insertLine`. `styleMode` controls how preview CSS must be authored. Treat it as a detected capability mode, not a framework guess: `scoped` means `@scope ([data-impeccable-variant="N"])` rules; `astro-global-prefixed` means explicit `[data-impeccable-variant="N"]` prefixes with the exact returned `styleTag`.

 ## Handle fallback
 
 When wrap returns `fallback: "agent-driven"`, you pick the source file yourself; the goal is unchanged: three preview variants now, and the accepted one persisted where the next build cannot wipe it.
 
 1. **Find where the element really lives** from the error payload: `element_not_in_source` + `generatedMatch` means the served HTML is generated, so find the generator's template or partial; `element_not_found` means runtime-injected, so find the rendering component or data source; `file_is_generated` resolves the same way. A purely visual change may belong in a shared stylesheet rather than a template.
-2. **Preview in the served file**: manually write the same wrapper scaffold `impeccable live-wrap` produces (`<!-- impeccable-variants-start ID --><div data-impeccable-variants="ID" data-impeccable-variant-count="3" style="display: contents">…</div><!-- end -->`) into the file the browser actually loaded, insert your variant divs, `--reply EVENT_ID done --file <served file>`. This edit is temporary; a regen wiping it is fine.

This edit is temporary; a regen wiping it is fine.
 3. **On accept, write to true source** (accept refuses generated files, so `_acceptResult.handled` is usually `false` here): structural change → template/component source; visual-only → the right stylesheet; content rendered from data → the data source or render logic. Then remove the temporary wrapper from the served file.
 4. **On discard**, just remove the temporary wrapper.

 ### Create or replace the visual world
 
 1. Name the product's unique mechanism in one sentence, the audience's real scene, its cultural home, and what this first surface must prove. Note the page this category always ships and its predictable opposite; both are the rut, kept out of the seven-candidate list. A brief that paints its own picture, a product name, a titled artifact, a governing metaphor, adds its literal reading to the rut: spend at most one candidate on it and derive the rest from elsewhere in the audience's world.
 2. From that cultural world, list seven concrete visual systems, artifacts, places, or rituals the audience knows by heart, each with one line on why it resonates and can carry the mechanism, ordered by resonance. The audience's world includes its graphic and screen traditions, not only its physical objects: the notation, publications, identity programs, data graphics, and interfaces it reads daily. A nameable abstract system (a school of poster, a documentation standard) is as concrete a candidate as any artifact. What would this thing look like as a physical object; what did its world look like before the web? Near-duplicates count once. When more than three of the seven share one material family, the derivation stopped at the subject's most obvious artifact; dig until the list spans at least three families.
 3. Turn that material into complete directions: each joins a reusable visual world to a concrete first-surface experience.
-4. Run `.agent/skills/impeccable/scripts/impeccable concept-seed --scope direction --mode <mode>` and follow what it prints. No substitute, no skip: on a new or replacement world, writing artifact code before this script has run and its assignment is acknowledged is a contract violation, whatever the harness, the model, or the time pressure; the roll is what keeps every run from converging on the category default. The script assigns the direction to build and deals catalog challengers. Fuse each challenger before judging it: the challenger supplies the form and its system grammar, the product supplies every fact, clarity wins conflicts. Weigh fused challengers against the assigned direction on exactly two axes, audience identification and product clarity. Losing to strong grounded material is a valid outcome; beating a thin or tool-monoculture list is the point.

A declined challenger is not spent: name the one discipline of its system the assigned direction lacks, and raise the assigned direction to match before presenting it.

 5. Present one direction, fully committed and already raised by the hand it beat, raises visible as named lines: world, first viewport, visitor path, signature interaction, cross-surface reach, honest risk. Route each challenger by verdict: winning and competitive challengers are full alternates with their QUALITY BAR cards and one-line case; declined challengers render demoted, compact and quiet, each carrying its verdict and what the direction kept from it, never full-size, never silently dropped, still adoptable on request. The verdict informs the user's choice, never pre-empts it; the demoted row is the hand's proof of judgment. A hand holds at most three full-card challengers: when the roll deals more, the three strongest join and the rest wait in the re-roll pool, noted in one line; dropping a challenger from the hand itself takes a named product-truth failure, disclosed. Add one card for your own top-ranked grounded candidate when it is not the assigned direction, kicker IMPECCABLE’S PICK, same anatomy as every card, with an honest risk line naming its familiarity when true: the strongest grounded direction is often where most runs in this category land, and the user deciding that trade is the point of showing it. Familiar and effective is a legitimate destination, not a failure of nerve; the pick card and the standing exit serve it at two depths. One pick card, never two, never a ranked list: a lineup of your candidates hands selection back to a taste function and invites the safest card. The pick never takes the lead position; when the dice assign your top candidate there is no pick card, and the assigned card notes it topped your list. Add re-roll with an optional one-line steer, in three registers: plain (a fresh hand, same spread), safer (your remaining conventional grounded candidates plus the canon against named competitors), bolder (foreign forms only, at full commitment). The register is the user's steering on the familiar-to-bold axis, never yours to pre-select; when the answer carries one, re-run the seed with `--register <value>` and the next `--reroll` round, and follow what it prints. A user saying "bolder" or "safer" while a direction round is open means these registers, never the bolder or harden commands. The two channels share this structure and differ only in richness: cards and boards on the decision page, names and one-liners through the structured tool, whose option list carries the assigned direction, the pick, the winning and competitive challengers, and the standing exit last; declined challengers fold into the assigned option's description as their kept lines, so the raise survives the text channel.
 
-The standing exit: every direction round offers one quiet, permanent alternative, the category standard, played straight. It is the user's door, never yours: never recommend it, never weigh it against the roll, never let it soften the dealt directions; the counterweights bind the unchosen default, not the chosen one. When the user takes it (the canon action, a safer-steer, or plain words asking for the familiar or competitor-like path), convention becomes the commitment: ask once for two or three products this should sit alongside, make their craft level the bar, and execute the canon at full fidelity, without irony or smuggled quirk. Record a standing preference as a brand commitment in PRODUCT.md. Re-roll eliminates every direction already shown, grounded and challenger alike; after two consecutive re-rolls, ask what quality is missing. Re-roll on your own only on named factual grounds, when the assigned direction cannot carry the product's truth or task; taste is never grounds. The user may re-roll freely, and a user- or brief-pinned direction beats the roll, always. Resolve collisions field by field: preserve every user- or brief-pinned constraint. In dimensions the brief leaves open, the assignment still binds through its topology, controls, state vocabulary, and ritual; when only its materials conflict with a pinned visual direction or PRODUCT.md brand commitment, translate that material expression and name the translation in the presented direction. A look mismatch is not grounds to re-roll. Present the decision visually: write an options payload with the assigned direction leading, its raised lines included; the pick card when one exists; the dealt challengers as alternates with their QUALITY BAR cards, verdicts, and kept lines; re-roll with its safer and bolder registers; steer; canon enabled; and `buildPath` carrying the recorded default with `toggle: true` whenever image generation exists (details in the build-path paragraph below). A degraded roll with no challengers still uses the page, as a single text-only card with re-roll. Give every card the same anatomy: thesis, palette, materials, first viewport, honest risk, and the challengers' case lines (`--schema` prints the exact shape); the page renders identity from these fields, demotes declined challengers to their row on its own, and a challenger's catalog image rides as labeled inspiration, never the promise of the build. Author `canonCard` too: the category standard as one honest card, same anatomy; the page keeps it subordinate, and the counterweights still bind you. Run `.agent/skills/impeccable/scripts/impeccable serve-question --start --payload <file>` (`--schema` first for the payload shape). It daemonizes, prints the page URL and a key, and exits; open that URL for the user, in-app browser first, then the system opener, then showing the URL. Collect the choice with `--wait --key <key>`, repeating while it exits 3; the ANSWER prints as JSON. An ANSWER of `{"optionId":"reroll"}` keeps the server alive and the page open on a loading hand: rerun concept-seed with the same `--scope` and `--mode` plus `--from <seed-key> --reroll <n>` (1 on the first re-roll, counting up), build the next payload, deliver it with `--update --key <same key> --payload <file>`, then return to `--wait` on that key. Never `--start` a second server or fall back to chat here: either strands the open tab on a hand that never arrives. Exit 4 means the page closed unanswered: re-present once through the structured question tool, and with no answer there either, proceed unattended with the assigned direction and state the assumptions. A harness that can leave a shell blocked in the background may run the script without `--start` and let it auto-open and block. Never predict the fallback: run the script, and only exit code 2 from starting it routes the decision to the structured tool; that exit is the fallback, never an error to retry.

 When image generation exists, every card also declares a `comp` path under `.impeccable/mocks/decision/`, the canon card included. Where the harness sandboxes its shell, start the page through the least-sandboxed command path it offers: a sandboxed shell cannot bind the board's port, and the first-attempt failure costs a retry every session. Serve the page first, then produce the comps; the page shimmer-waits per slot and the user may answer before they land. Each card's image is that direction's north-star comp at full fidelity under [visualize.md](visualize.md)'s comp discipline: the requested surface's first viewport, structure-led prompt, real product name and real content, no invented commercial claims, in that card's own palette, type character, and material world, committed all the way. Generation takes the same time at any fidelity, so an unfinished draft pays comp cost for draft quality; fairness between cards is equal fidelity in each card's own grammar, one surface, one aspect, never shared unfinishedness. The frame's aspect is the surface's own: portrait at device viewport for a native app or mobile-first surface, landscape for desktop web; the decision page adapts to either, and a phone screen comped landscape is a broken frame, not a neutral default. Produce in reading order, the assigned card, then the pick, then the full-card hand, then canon, each file written with its prompt sidecar the moment it is done, so a re-roll's spend front-loads onto the cards read first; declined challengers get no comp, their catalog thumb is their face. With parallel subagents, fan out one agent per card: each spawn is the shipped asset producer with a single-comp packet, that card's fields, PRODUCT.md, the shared frame, and the card's declared path, up to four in flight. Regenerate inline any slot still empty when its agent returns; drop without ceremony any slot still empty when the user answers. No other supervision is owed. Without parallel subagents, generate in the main thread after serving, same order, and let the harness's own generation display carry the progress; the wait for the answer follows the last file. The chosen card's comp is not spent by the choice: comp-led, it enters the comp round as compositional option one; code-led, it returns at the finish review as the critique reference, what the image dared that the build did not. Unchosen comps stay in `.impeccable/mocks/decision/` as the round's spent hand; they carry no approval and imply none. With no image generation, cards carry their identity in palette chips and facts, and that page is complete, not a lesser version; the page then also demotes every challenger's catalog art to a labeled thumbnail on its own, because salience must encode the verdict, never the accident of which cards have images.

A direction contract is durable route or artifact strategy, so create or update the brief even when no other surface strategy needs persistence. Keep the contract to six short blocks and 150 words at most. THESIS: the one idea this surface owns and the category-default arrangement it refuses. OWN-WORLD: the palette and component language, specific enough to be recognizable with all content removed. STORY: what the visitor understands, believes, and does. FIRST VIEWPORT: the exact composition, what is where and at what scale, and where the primary action sits. FORM: the chosen form, its position on your ordered list, and the seed key the script printed. Close with one more line, FINISH: the run's exit condition, verbatim "unreviewed and undocumented is unfinished; this build ends with the finish review, the verdict, DESIGN.md, and every shipping raster carrying its provenance". The surface brief is the reminder later agents reload across edits and sessions: a page that looks complete with the FINISH line undischarged is not done, it is abandoned at the finish line. If a block reads like a mood, the direction is not decided yet; the finishing review audits the render against this contract.
-
-Never copy the direction contract into implementation source or any browser-delivered artifact. This includes HTML or framework comments, hidden DOM, `<template>` elements, `data-*` attributes, rendered JSX or TSX output, serialized props or state, React Server Component payloads, client bundles, metadata or JSON-LD, accessibility-only text, and files served beside the artifact. A compiler or optimizer removing development metadata is not a safety boundary. Reviewers and documenters receive the contract from the surface brief.
+Before code, state the chosen direction as a contract in the artifact's opening comment, five short blocks, 150 words at most, in a form that survives the production build: an HTML comment in the emitted markup, never only a templating-frontmatter comment, placed as the first child of the document's body in the root layout, never inside a slotted or child component (some compilers, Astro among them, strip a slot's leading comment while keeping deeper ones). After the first production build, grep the built output for the seed key; a contract the build erased is a contract nobody can audit. THESIS: the one idea this surface owns and the category-default arrangement it refuses. OWN-WORLD: the palette and component language, specific enough to be recognizable with all content removed. STORY: what the visitor understands, believes, and does. FIRST VIEWPORT: the exact composition, what is where and at what scale, and where the primary action sits. FORM: the chosen form, its position on your ordered list, and the seed key the script printed. Close with one more line, FINISH: the run's exit condition, verbatim "unreviewed and undocumented is unfinished; this build ends with the finish review, the verdict, and DESIGN.md". The comment tops the artifact you re-open on every edit, the one reminder that survives a long build: a page that looks complete with the FINISH line undischarged is not done, it is abandoned at the finish line. If a block reads like a mood, the direction is not decided yet; the finishing review audits the render against this contract.
 
 On a new or replacement world, DESIGN.md is written at finish, from the built world, by the shipped documenter (section 7); a rulebook written before the build gets defended against reality instead of describing it, and hands the design-system detector an unstable target. A new world shipped with no DESIGN.md is still an incomplete run. An ordinary extension does not rewrite DESIGN.md.
 
-Read the existing surface brief before updating it:
+If the work establishes durable strategy for a route or artifact, read its existing surface brief, then update it:
 
-`.agent/skills/impeccable/scripts/impeccable surface-brief read <primary-target>`
+`node .agent/skills/impeccable/scripts/surface-brief.mjs read <primary-target>`
 
-`.agent/skills/impeccable/scripts/impeccable surface-brief write <primary-target> <body-file> [related-target ...]`
-
-After writing, read the brief once more and verify that all six contract blocks and the seed key are present before building.
+`node .agent/skills/impeccable/scripts/surface-brief.mjs write <primary-target> <body-file> [related-target ...]`
 
 Keep the brief small: scope and visitor mode; audience, job, action/task, proof/content, and constraints; chosen direction and memorable moment; unresolved decisions. Do not copy global product truth or DESIGN.md tokens into it.
 
-On a comp-led build, whenever any image generation is available (a harness-native tool or the API fallback `impeccable context` reports), the locked direction is visualized before it is built, never skipped: load [visualize.md](visualize.md) and follow it, three compositional options put before the user for approval, the chosen card's decision comp plus two variations. This step is proven to produce the most compositional and ambitious work. On a code-led build the comp round is skipped by contract, never by drift: the ambition it would have carried lives in the direction contract's FIRST VIEWPORT block and named signature interaction, and the finish reviewer audits those promises in behavior.

 For `shape`, return the selected direction to [shape.md](shape.md) and stop before persistence or implementation.
 
 ## 6. Build with full commitment
 
-Build the assigned direction, not a safer interpretation of it. The form supplies structure, reading order, component conventions, and native motion; the product supplies every fact. Commit every atom: nav, buttons, inputs, and links are rebuilt in the form's vocabulary, and a stock component inside a committed form is a lapse. Land the first build fully committed; the passes that follow exist to make the committed thing clear and effective, never to dilute it. In unattended work, the safe rendition is the known risk.
+When an approved comp exists, the comp is king, and the build happens in phases. The comp is a spatial contract, not a mood board: only the user can downgrade its authority, in explicit words, and difficulty never infers a downgrade. Phase one is reproduction: rebuild the comp at its own breakpoint until a screenshot at the comp's width and height overlaps it near pixel-perfectly, materials, components, elevation, assets, and implied design language included. Exactly three concessions exist: fonts (the closest obtainable face), icons (exact match unless the user already chose an icon library), and genuine defects in the generated comp such as spelling errors. Everything else must match, and models systematically believe their HTML, CSS, and SVG recreation succeeded when it did not, so the overlap comparison is the authority, never your conviction: set the screenshot beside the freshly reopened comp image at identical dimensions after every region, never beside your memory of it, and when a region keeps losing that comparison, stop recreating it in code and produce it as a rendered asset composited into the page. The comp also outranks every written record of it: when the recorded brief or inventory commits to less than the comp shows, a softer texture, a sparser field, a sculpted plate reduced to flat CSS, correct the record upward to the comp; qualifiers like subtle, restrained, and low-contrast, and counts rounded down to a comfortable fraction, are how approved materials die between approval and build. A produced material must then survive to the screen: a texture buried under a nearly opaque color wash ships the wash, not the material, so judge every material by the screenshot beside the comp, never by the stylesheet. Only when reproduction holds does phase two begin: static regions that should live become animated or interactive, reveals and motion are added, then responsiveness across the surface's devices. Where the comp does not cover the whole surface, continue building the remainder inside the comp's recorded world and design language; a component the comp never shows inherits the recorded system's corner language, line weights, and materials, and may not introduce container styles, border weights, or chrome the comp never uses.
 
-### Comp-led: the comp is a measured contract
-
-When an approved comp exists, it is a spatial contract, not a mood board: only the user can downgrade its authority, in explicit words. Models systematically believe their HTML, CSS, and SVG recreation of an image succeeded when it did not, so the build runs as a state machine on disk whose gates measure the screen against the comp instead of asking you to remember it. Start it once, and let it tell you what is next:
-
-`.agent/skills/impeccable/scripts/impeccable build-phase start --direction <seed key> --kind <assigned|pick|challenger|canon>` right after the direction choice (this is also the choice ping; the roll's output names the exact command), or `start --comp <approved comp>` when a surface round already locked one.
-
-Then, in order, each closed by `.agent/skills/impeccable/scripts/impeccable build-phase advance` (every verb below runs as `.agent/skills/impeccable/scripts/impeccable <verb>`; exit 2 means the gate failed and printed why; fix that and advance again; write nothing for a later phase while an earlier gate is open):
-
-0. **comps.** The comp round from [visualize.md](visualize.md): three compositional comps of the requested surface at its own viewport under `.impeccable/mocks/`, each with a prompt sidecar, put in front of the user; the chosen one's sidecar gets `"approved": true`. The gate counts them and reads the approval; a `start --comp` skips this phase because it already happened.
-The comp-led path is a frontier-tier job: it asks the builder to hold a measured layout, place plates at their boxes, and act on numeric readings across a dozen attempts. Smaller or faster models produce a recognisable page and stall under the hero gate; if the model in hand is one of those, say so before the direction round and take the code-led path, or expect the run to end at the hero with its readings unmet.
-
-1. **spec.** Measure the comp: `impeccable comp-spec --comp <comp> --grid` writes a coordinate grid over the comp; open it, name every salient region by grid span in a regions file (text and control regions snap to the largest ink mass inside their span, so a headline named B1:E4 measures as the headline and not the column beside it; `snap: false` keeps the span, and an explicit `box` is taken as drawn) (kind `plate` / `image` / `texture` for anything painted: every illustration, photograph, figure, product object, and material texture; `text` / `control` / `chrome` for what code draws; every region carries a `note` saying what the comp shows there, which the plate prompt and the gate messages read), and run `impeccable comp-spec --comp <comp> --regions <file>`. The spec carries each region's box, sampled palette, and medium; `impeccable comp-spec --print` is the build's reference from here on. Type is measured, not guessed: `impeccable font-match --measure <text region>` reads the comp's cap height, width class, and weight off the pixels, and `impeccable font-match --rank <region> --text "..."` takes its candidates from a fingerprint index of the Google Fonts catalog (the nearest faces to the crop's shape) plus any names you pass with `--candidates`, renders them at that cap height with the region's words, and ranks them by fingerprint distance (its `USE` line is the CSS; its proof sheet shows the comp over the top three); with no browser resolvable it records the catalog's nearest face and says the size is estimated, which is still the choice to build on. Do not install a browser to rank, and never write a `chosen` face into the spec by hand: the gate accepts only what font-match wrote. The spec gate refuses to close until the lead text region is measured and ranked. A region note that describes painted material (a diagram, drawing, photograph, texture) under a code kind is refused at the spec: reclassify it as a plate, or reword the note if code really draws it. The script refuses a regions file that leaves comp ink unnamed (callouts, a parts table, a notes block): what is never named can never be missing, so everything the comp shows gets a region. It also refuses a `text` / `control` / `chrome` region larger than a quarter of the comp: that is a column, not an element, and a column scored as one region hides the plates, tables, and notes inside it. Name each element inside it (`container: true` only when it truly is one undivided element). Anything drawn is a plate: an inline SVG past an icon's budget (a diagram, notation, leader lines with arrows, a "quick approximation" of the artwork) is refused at the hero; icon-sized SVG (under 64px, a few paths) is fine, and a chart the page draws from data at runtime is a chart, not an illustration. Callout lines and arrows that annotate a drawing belong to that drawing's plate, with only their labels set as text. A crop of the comp is never a plate (the plates gate refuses a file that is a resample of the comp region: the comp's grain, its neighbours' edges, and its resolution would ship as the artwork); the crop is the reference the plate is generated from. A plate region's box has to hold its whole artwork with a margin: the spec measures the artwork's contact with the box edges and refuses a box that cuts through it (`bleed: true` only when the page really crops it there), because a plate placed with `object-fit: cover` on such a box shows the artwork minus the side the box lost. Anything not in the spec does not exist on the page: no borders, rules, containers, or chrome the comp does not show. Only three concessions exist: fonts (the closest obtainable face), icon glyphs (close enough, exact if the user chose an icon library; this covers the pictogram only, never a control's chrome, so a chevron, an arrow, a dropdown's border and fill, a button's shape are the comp's), and genuine defects in the comp such as spelling errors.
-2. **plates.** Every raster region ships as a plate: an illustration, photo, or figure regenerated at asset resolution from its comp crop, UI text removed, at its `plate` path (ink on flat ground is generated on a chroma key and keyed to alpha, so it sits on the page's own ground rather than a second paper); a texture (paper, cloth, grain) is a clean patch of the comp region mirror-tiled to size, generated only when no clean patch exists. `impeccable generate-image --plate <id>` does one region end to end and scores it against the crop; a harness-native image tool takes the crop (`impeccable comp-spec --crop <id>`) as its input image and `impeccable comp-spec --plate-prompt <id>` as its prompt, then `impeccable embed-prompt`. With parallel subagents, spawn the shipped asset producer (`impeccable-asset-producer`; `impeccable_asset_producer` in codex; `/impeccable-asset-producer` in Cursor; on GitHub Copilot say "Use the impeccable-asset-producer agent") with the spec path and let it produce them all; without subagents, produce them here. A crop of the comp is a reference, never a shipping pixel. The gate checks every plate exists, is at least 1.5x the region's size, and reads as the region. Page code waits for this gate: a page written before its plates exist is a page that draws its material in CSS. A single-file deliverable changes nothing here: the plate is produced the same way and inlined as a data URI. `--force` exists for one case only, the user downgrading the comp's authority in words you quote in `--reason`; the script refuses every other reason.
-3. **hero.** `impeccable build-phase scaffold` first: it writes the measured layout as CSS custom properties (`.impeccable/build/scaffold/layout.css`: `--r-<id>-x/y/w/h` in % of the comp, plus cap height, font-size, family, and weight where measured) and a reference page (`hero-reference.html`) with every region at its box and every plate placed. Bind the numbers to your own semantic structure, an element per region; the reference is a check on positions, never the page, and overlapping boxes are overlapping boxes. Then build only the first viewport, at the comp's own dimensions, the comp's words copied verbatim (the user approved that comp with those words; rewording is a stated decision after the hero passes, never a silent one inside it), every text region sized from its measured cap height and set in its ranked face, plates first: place every plate at its spec box (`object-fit: cover`, an `<img>`, a background image, or an inlined data URI named for it) before any text or control, capture into `.impeccable/review/hero-repro.png`, run `impeccable build-phase record hero` once so you see the plate regions read as match before any text exists, then lay the semantic layer over the plates from the spec's palette and boxes and advance. The gate first refuses while any plate is unreferenced by the source, then runs `impeccable comp-diff`, writes `.impeccable/review/diff/hero/` (side-by-side, heatmap, one paired crop per region, `report.json`), and passes at 72% overall with no hard veto outstanding (a missing region, a contradicted plate or text block, an SVG illustration, a clipped plate, invented ink block at any score); above the bar, the numeric readings become advisories printed with the pass, and the polish pass before responsive is where they get fixed: the gate also reads each text region's cap height, line count, weight, ink colour, and position against the comp, each chrome strip's height off its rule, and the frame for ink where the comp is calm (a kicker, an extra nav item, a divider), and says each miss as a number ("cap height 78px in the build, 103px in the comp"); those numbers are the edit. When it fails, open the region crops it lists, in order, before editing: a region scored `missing` needs its material, `contradicted` needs its structure re-derived from the spec box, `drift` is where size and spacing edits belong; the gate refuses a third attempt that only nudges values on the same region. This is where the run's ambition is won or lost, and a retry here costs minutes where a rebuild verdict at the finish costs the run.
-4. **sections.** Build the rest of the surface inside the spec's system: the same corner language, line weights, and palette, and nothing the comp never shows. Where the comp does not cover a region, it inherits the recorded system.
-5. **motion.** The signature interaction, reveals, and motion, orchestrated once rather than scattered.
-6. **responsive.** The other viewports, and the first viewport at common desktop widths (1280 to 1600), not only at the comp's exact size: fluid columns, no fixed-pixel grid that wraps a hundred pixels narrower. Capture `desktop.png` (1440 wide, full page) and `mobile.png` (390 wide) into `.impeccable/review/`; the gate diffs the desktop capture against the comp and refuses a first viewport that only held at the comp's width. A comp'd surface that is mobile-first was comped portrait; the plates were produced for that frame.
-
-### Code-led
-
-No comp and no apology for it: the ambition lives in the direction contract's FIRST VIEWPORT block and the named signature interaction, and the finish reviewer audits those promises in behavior. The chosen decision comp rides to the finish review as the critique reference.
-
-### Both paths
+Build the assigned direction, not a safer interpretation of it. The form supplies structure, reading order, component conventions, and native motion; the product supplies every fact. Commit every atom: nav, buttons, inputs, and links are rebuilt in the form's vocabulary, and a stock component inside a committed form is a lapse. Land the first build fully committed; committing is the hard part, and the passes that follow exist to make the committed thing clear and effective, never to dilute it. In unattended work, the safe rendition is the known risk.
 
 - **The first viewport is a thesis, not a header.** Demonstrate the mechanism immediately, at the scale the form has in life; do not trap the concept inside a standard hero or card shell. The memory test: if someone left after one viewport, what would they describe an hour later? If the honest answer is a mood, the concept has not committed yet.
-- **Prove, don't claim.** Show the subject doing its job: the interface at work, the mechanism dramatized, specifics a competitor could not copy-paste. Demonstration data is design material: author it at full fidelity and label it synthetic; claims stay uninventable.
-- **Author the assets; never substitute chrome.** Great surfaces live on carefully made content: names, entries, copy, covers, thumbnails, textures. In greenfield work every blank the ask round left open is yours to author at production fidelity; content is authorable, claims are labelable, no section is omittable. Gradients, glass, generic icon tiles, and many-vertex `clip-path` polygons where an authored asset belongs are the gap wearing chrome; the detector flags the last two.
-- **Build the form's web leverage.** When the chosen world names a technique (canvas, WebGL, view transitions, generative motion), build the technique itself, not a static imitation of it.
+- **Prove the hero before building past it.** When an approved comp exists, render the first viewport, capture it at the comp's own pixel dimensions, and set it beside the comp's first viewport before any later section: the hero carries the run's ambition, and every following section inherits its shortfall. Save that capture as `.impeccable/review/hero-repro.png` (create the directory); the finish reviewer verifies it exists, so a skipped checkpoint is a visible checkpoint. Judge scale and density as quantities, a field at a tenth of the comp's coverage or type at half its weight is a different design, and a five-minute retry here is what a rebuild verdict at the finish costs when this check is skipped.
+- **Prove, don't claim.** Show the subject doing its job: the interface at work, the mechanism dramatized, specifics a competitor could not copy-paste. Sections that restate a claim in different words add length, not substance. Demonstration data is design material: author it at full fidelity and label it synthetic; claims stay uninventable.
+- **Author the assets; never substitute chrome.** Great surfaces live on carefully made content: names, entries, copy, covers, thumbnails, textures. In greenfield work every blank the ask round left open is yours to author at production fidelity; content is authorable, claims are labelable, no section is omittable. An unanswered commercial claim ships as a clearly marked placeholder on the user's replacement list. When image generation exists, producing the design's imagery is part of building, at the scale the composition needs: a viewport that wants atmosphere gets a full-bleed layered scene, and a library of small centered subjects standardized for tidiness forecloses it. Gradients, glass, and generic icon tiles where an authored asset belongs are the gap wearing chrome; icons drawn in the world's own grammar are the remedy, not the target.
+- **Build the form's web leverage.** When the chosen world names a technique (canvas, WebGL, view transitions, generative motion), build the technique itself, not a static imitation of it; the graceful fallback serves constrained clients, it is not the default experience.
 - **Pace the scroll like a studio.** Vary density, scale, image, motion, and quiet inside one grammar; a dense passage earns a quiet one, and the page ends anchored by a real close. One spacing rhythm throughout, with more space above a heading than below it.
 - **Use real, verified imagery when the brief implies it.** Search for the subject's physical object rather than the category; one decisive photo beats five mediocre ones. Verify stock URLs resolve.
-- **Author motion as material.** Give the page the form's native motion once, orchestrated, rather than scattered hover effects. Bound expensive effects and keep content visible by default.
+- **Author motion as material.** The form has native motion, what it does in life between states; give the page that motion once, orchestrated, rather than scattered hover effects. Bound expensive effects and keep content visible by default.
 
 Preserve semantics, accessibility, performance, responsiveness, project conventions, and working behavior.
 
 ## 7. Inspect and finish
 
-Inspect the surface's target sizes in one batched screenshot round: desktop and mobile on the web; on a native platform (`ios` / `android` / `adaptive`), the shipped device classes per OS, captured from the simulator or emulator the way the platform reference's Verifying the build section describes. When the harness reports the user's actual viewport (an in-app browser's size, a named resolution), add that width to the set: the width that breaks is the one the user sees first. Critique the render against the user's request and the direction contract, fix material gaps, and confirm with one final round; two rounds is the ceiling, and fixes batch between them rather than earning per-tweak screenshots. On a comp-led build, run `.agent/skills/impeccable/scripts/impeccable comp-diff --comp <approved comp> --build .impeccable/review/desktop.png --spec .impeccable/build/spec.json --out-dir .impeccable/review/diff/final` and read its region rows and paired crops as the critique: the side-by-side is the view the build thread never has on its own, and a region it scores missing or contradicted is a fix whatever the page looks like from memory. Never judge fidelity from one full-page thumbnail; it hides exactly the failures that matter. On a Persuade surface, verify the mode did its job: a first-time visitor should know what this is, why it matters, and what to do within seconds, in the form's own vocabulary.

On a Persuade surface, verify the mode did its job: a first-time visitor should know what this is, why it matters, and what to do within seconds, in the form's own vocabulary.
 
 A capture is evidence only when it is valid, and you validate before you send. Settle or disable entrance motion first: an element hidden by animation timing reads as a missing element and gets fixed into a regression. Capture full-page shots from the document top. Capture the comp comparison at the comp's own pixel dimensions. Then open every file once and confirm it shows what its name claims: no black or blank regions, no wrong section behind a right filename, no half-loaded state. A malformed capture sent onward costs the whole round; the reviewer answers it with `disposition: recapture` and nothing it reviewed binds.
 
-After the second inspection round the build thread's polishing is over: no further defect hunts, micro-edit scripts, or rebuilds here; whatever remains ships through the handoffs, where a fresh context does the finding better and cheaper. On the web, where this harness runs no design hook, run `.agent/skills/impeccable/scripts/impeccable detect --json` on the changed targets once here, fix what is mechanical, and pass the remaining findings to the reviewer; a hookless web build that skips this ships every tell the hook exists to catch. A native platform skips the detector entirely: it reads HTML and CSS and has no verdict on native code, so the reviewer's floor check is the only slop gate and the input packet says so. Capture the screenshots into `.impeccable/review/`, one file per captured viewport (on the web, `desktop.png` and `mobile.png`, plus `user-<width>.png` whenever the user's viewport joined the inspected set; on native, one per device class, such as `phone.png` and `tablet.png`, suffixed per OS on adaptive), creating that directory when the harness does not; the paths you pass the reviewer are its spec, every viewport you inspected is named required in the packet, and that directory is where it looks when a passed path is missing.

 Act on the disposition word; there are exactly four. **recapture**: the evidence failed, not the build. Recapture what the return names under the capture-validity rules, then run a full review over the new evidence. A review conducted on invalid evidence binds nothing, and a verdict pass may never follow it. **rebuild**: fidelity failed wholesale, not in patches. Skip the fix batch and execute the rebuild immediately: re-derive the named regions, produce the named assets, and send the result back for a fresh full review, never a verdict pass; a rebuild replaces regions wholesale, so the whole matrix runs again over the recaptures. Tell the user what is happening rather than asking permission to fix a failure. Consult the user only on a second rebuild directive, both verdicts on the table, or when rebuilding would discard content the user approved. **ship**: nothing is owed; report the verdict at its scope and continue to the documenter. **fix**: apply the material fixes in one batch, rebuild once, and recapture the same viewports over the same files. A recapture measures positions, loading, and overflow; it cannot measure whether a fix reached the quality the finding named, so send the recaptured screenshots back to the same reviewer for a verdict scoring every material fix resolved, partial, or unresolved (through the harness's agent continuation; without one, run the scoring fresh from [degraded/finish-reviewer.md](degraded/finish-reviewer.md)'s Verdict Pass). Fixes scored partial or unresolved get another batch, recapture, and verdict. Two rounds is the budget an unattended run ends at; an attended session's ceiling belongs to the user, so when the second verdict still lists open items, put the table in front of them and let them choose between shipping as it stands and funding another round. Whoever decides, stop the moment a round resolves nothing, and the reviewer's findings are the only list you work from, never your own re-opened hunt. Do not run a second detector.
 
-A rebuild and a fix round share one asset rule: a raster either round creates or replaces is still asset work under [visualize.md](visualize.md)'s Produce section and keeps its **provenance** like every build raster, and a raster the round abandons is deleted in the same batch. Before either round's result goes back for review or verdict, run `.agent/skills/impeccable/scripts/impeccable embed-prompt --scan <asset-dir...>` over the directories the artifact's rasters ship from and clear every file it reports by embedding what it is missing: the exact generation prompt for a produced raster, the origin for a sourced, stock, or pre-existing one. The scan only reads; deletion is reserved for rasters the round abandoned, never for a file the scan flagged.
-
 Report the final verdict under the reviewer's own disposition word and at its actual scope. A verdict pass scores the listed fixes and nothing else: "the reviewer scored all three fixes resolved" is a claim it supports, "no material issues remain" is not. A table with open material findings is never announced as a pass, never softened, and never dressed as whole-surface approval when only a fix list was scored. When the user answers a ship with evidence against it, their own screenshot, a named mismatch with the comp, that evidence outranks every capture you made: put their material in the packet and spawn a fresh reviewer for a new full review. Patching inline and self-certifying is how a rejected page ships twice.
 
 Then spawn the shipped documenter, `impeccable-documenter` (`impeccable_documenter` in codex), with the project root, the artifact path, the direction contract, PRODUCT.md, the [document.md](document.md) reference path, and the boundary to write at; it records DESIGN.md and the sidecar from the built world, ground truth over intention; without subagents the pass runs from [degraded/documenter.md](degraded/documenter.md). The documenter runs after the last correction lands: when any fix round follows the documentation, re-run the documenter over the changed surface, because a DESIGN.md describing a layout that no longer exists turns defects into system guidance. A clean detector pass is not finished; finished is the contract kept, the comp honored, the review closed, and the system recorded.

 ## Generate three compositional options
 
-The comp round runs inside the build's phase state: `impeccable build-phase start --direction <seed key> --kind <...>` has already run (the roll's output names the command) and its `comps` phase is open before the first comp is generated; a comp rendered before that sits outside the state, and a session resumed from that point has no phases to follow. `impeccable generate-image` refuses to write under `.impeccable/mocks/` until start has run; a harness-native image tool is bound by the same order.
-
-Render three distinct high-fidelity north-star comps of the requested surface, saved under `.impeccable/mocks/` so they survive the session. Comp at the surface's own viewport: portrait at device size for a native app or mobile-first surface, desktop landscape otherwise; a phone screen comped landscape misstates the composition before anything is built against it. Comps are the build thread's own work, never delegated: the thread that writes the prompts holds the direction's full context and has seen every comp when the build starts. Open every image by its workspace-relative path; sandboxed viewers reject absolute paths, and everything under the project root has a relative one. Base the comps on real content and the surface concepts already developed with the user. On an established world, anchor every comp on the real identity: capture a screenshot of a representative existing page and pass it as a reference image (the harness image tool's input image, or `impeccable generate-image --ref`); the prompt leads with the new surface's structure while the reference carries palette, type, and component character, because DESIGN.md words alone drift where a pixel reference does not. Name what the reference contributes and what it must not: chrome, palette, type, and component character carry over; the reference page's own content does not, and a banner, hero, or card lifted verbatim is the reference leaking, not fidelity. Three is the number: one comp invites rubber-stamping; the spread between three surfaces the composition worth building. The chosen card's decision comp is the first of the three: it already renders this direction at full fidelity under this discipline, so generate two more that vary what the first held fixed, and send all three to the approval point together. Only a round arriving with no decision comp (a degraded roll, an identity-mode page, a direction pinned without the decision round) renders all three here.

 - A comp is a designed surface, not a picture of the subject. Lead the prompt with the surface's own structure: the regions this design has, named in order with their scale relationships; a page with no navigation says so instead of inventing one, and an unconventional surface states its unconventional skeleton. A prompt that leads with atmosphere gets a vignette back: the model paints the fish market instead of the fish market's website. Self-check every render: if it could hang as a poster, or reads as a photograph with some text on it, it is not a comp; regenerate with the layout scaffold stated more literally.
 - The inverse is also a failure: a surface with none of its subject in it. The subject appears as the content the regions hold; the world dresses the frame and never displaces what the frame shows. The deletion usually rides in on the prompt's exclusion list, so exclusions bind invented claims, and a medium ban belongs to the committed imagery stance, never to caution. Before accepting a render, point at the subject; a render that depicts everything about the world and nothing of the subject fails however faithful its atmosphere. Regenerate with the subject's content named region by region.

-## After approval: the comp becomes a spec
+## Inventory implementation fidelity
 
-The approved comp is a north star for translation into semantic, responsive, accessible code, never a license to recompose: keeping the palette and mood while redrawing the topology is a second art direction. Do not rasterize core UI text or controls. Do not substitute a different visual driver after approval without asking.
+Before building, read the approved comp as a design system and record it in the brief: component grammar, corner language, line weights, elevation treatment, and the type ramp. Everything the comp does not show gets built from this record; without it the fallback is the model's stock kit of square boxes, 1px grids, bento cells, and hard shadows. Then inventory the comp's major visible ingredients in writing (a short table in the surface brief or working notes; the finish reviewer audits shipped assets against it) and choose an implementation medium for each: semantic HTML/CSS/SVG, existing project asset, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission. The same inventory names the comp's compositional commitments: navigation items and icons, headline levels and their scale relationship, signature geometry such as seams, masks, and overlaps, and each section's arrangement and density. The primary action gets its own row with its own medium: when the comp dissolves, stamps, erodes, or otherwise physically works the main CTA, that treatment is signature material on the page's most important element, and shrinking it to a border trick is the compliance-token version of commitment. An element never written down is the element the build silently drops; the direction contract's 150 words cannot carry this list, so it lives here.
 
-What the comp shows is measured, not remembered. new-work.md section 6 runs the build as phases (`impeccable build-phase`): the spec phase turns the comp into region boxes with sampled palettes (`impeccable comp-spec`), and the medium of every region follows from what the pixels are, never from what feels buildable: a figure, a product object, machinery, any illustration with perspective, shading, or drawing skill in it, and any texture by name (woven cloth, paper grain, fabric, leather, brushed metal) is a `plate` / `image` / `texture` region and ships as a raster; text, controls, chrome, diagrams with countable elements, flat shape systems, and anything that must move, scale, or respond are semantic. Writing "CSS" for a sculpted panel's finish, or a many-vertex `clip-path` for a torn edge, is the quiet deletion of the approved design; the detector's organic-clip-path and buried-raster rules and the hero gate's region scores catch it. Dropping an image-native region is a scope decision the user makes at the approval point, never a silent flattening after it. Generated imagery is a material, not a claim: evidence rules bind assertions, specs, testimonials, and photographs presented as real, never render fidelity.
+The medium column is where an approved design most often dies, so it obeys a gate: the medium is decided by what the comp region shows, never by what feels buildable in the current stack. A human figure, a product object, machinery, or any material with lighting and depth is raster whatever the stack; so is any texture by name alone: woven cloth, paper grain, fabric, leather, brushed metal need no depth argument, because a CSS gradient is not a texture medium and "layered CSS textures" is not a medium at all. Writing "silhouette" for a photographic figure, or "CSS" for a sculpted panel's finish, is not a medium choice; it is the quiet deletion of the approved design, and it is how a comp full of physical material becomes a flat page with the same section order. Style does not move this boundary: a comp region with perspective, shading, figure drawing, or dense mechanical detail is illustration however line-drawn it looks, and no build session can author illustration as vectors, so it regenerates as raster like any photograph. Authored SVG covers what a session can specify exactly (diagrams with countable elements, controls, flat shape systems) and ends where drawing skill begins; an instruction-manual world keeps its illustrations as line-art illustrations, not diagrams. Produce such regions by regenerating them cleanly, with the approved comp and its embedded prompt as the reference for a fresh render at asset resolution; never crop pixels out of the comp itself, whose effective resolution sits far below asset grade. Dropping an image-native region is a scope decision the user makes at the approval point, never a silent flattening after it. Generated imagery is a material, not a claim: evidence rules bind assertions, specs, testimonials, and photographs presented as real, never render fidelity; "no photography on hand" forbids fake proof, not an illustrated hero.
 
-## Plates and provenance
+The gate runs both ways: precise geometry, hard-edged shape systems, diagrams, expressive motion, shaders, and anything interactive are vector and GPU territory (SVG, canvas, WebGL), where a raster flattens what should move, scale, and respond. A field or texture built from many small elements carries a quantity commitment either way: write down its approximate density and coverage ("thousands of glyphs over two-thirds of the fold, dense at the top fading into the path"), because a field rebuilt at a tenth of its density passes every checklist and still is not the design. TYPE rows carry the same discipline: name the face's compression class, and render one headline word against the comp before building on it; a visibly wider or lighter silhouette means the face is wrong, and every section built on it inherits the miss. Raster is for what the world paints; code is for what the world draws, animates, or reacts with, and choosing code there is ambition, not economy. Every `produce` entry is produced before the build ships, through the asset producer or in the current thread; an inventory with unproduced entries is an unfinished build, and this gate is where imagery-free pages come from when it is skipped.
 
-Every raster region's plate is produced in the plates phase, before any page code, by the shipped asset producer or in the current thread (`impeccable generate-image --plate <id>`, or the harness image tool with the crop as input and the spec's plate prompt). Generation context is part of the asset: after generating any image with any tool, run `.agent/skills/impeccable/scripts/impeccable embed-prompt <image> --prompt "<prompt>"` with the exact string the tool received (`impeccable generate-image` does this itself), so the intent lives inside the file; `--read` recovers it, `--scan <dir>` lists rasters still missing one. The embedded prompt plus the region's row in the spec is the raster's **provenance**, and every raster the artifact references carries it; a sourced, stock, or pre-existing raster embeds its origin instead. A raster created or replaced later, in a fix batch or a reviewer's rebuild, is produced the same way; a raster a fix abandons is deleted in the same batch.
+Pay special attention to the dominant composition, signature use, image-native content, second-fold system, and any interaction the still image only implies.
 
-Convert images with a converter `impeccable context` reported at boot (the IMAGE_TOOLS line); probe only when it reported none, at most once per session, never per image.
+The comp is a north star, not something to trace, and know what that allows: translation into semantic, responsive, accessible code, never recomposition. Keeping the palette and mood while redrawing the topology is a second art direction, not an adaptation. Do not rasterize core UI text or controls. Do not substitute a different visual driver after approval without asking.
 
-Return to [new-work.md](new-work.md) for the direction contract, the phased build, and the finishing pass.
+## Produce only the assets the build needs
+
+Generation context is part of the asset: a build composed by a thread that never saw the prompts places assets it does not understand. Prefer generating build-critical imagery in the build thread when the budget allows; when a subagent produces assets instead, every asset carries its prompt, and the builder reads those prompts before composing. The carrier is uniform across harnesses: after generating any image with any tool, native or `generate-image.mjs` (which does it automatically), run `node .agent/skills/impeccable/scripts/embed-prompt.mjs <image> --prompt "<the prompt used>"` so the intent lives inside the file and survives copies between machines and harnesses; `--read` recovers it from any impeccable-generated image.
+
+When the harness runs subagents, spawn the shipped asset producer every time, even when the inventory's produce bucket looks empty: its manifest is the independent second opinion on your media, and the runs that skipped the spawn are the runs whose cotton became CSS. An honestly empty manifest costs one cheap spawn; a wrongly empty produce bucket costs the build its materials. Use `impeccable-asset-producer` (`impeccable_asset_producer` in codex; `/impeccable-asset-producer` in Cursor; on GitHub Copilot say "Use the impeccable-asset-producer agent"): give it the approved comp, output paths, required dimensions and formats, transparency needs, crop notes, and what must remain semantic code. Without subagents, produce the minimum required assets in the current thread by the book: load [degraded/asset-producer.md](degraded/asset-producer.md) and follow it inline, with whatever generation exists.
+

+ * its own dice.
+ *
+ * This script rolls them from outside, the same trick that made the
+ * palette seed work:
+ *   - ASSIGNED INDEX: which entry of the model's own resonance-ordered
+ *     shortlist gets built. The assignment is the dice: it never chooses an
+ *     ungrounded ingredient, it only refuses the argmax rut. Attended runs
+ *     present the assigned direction and offer re-roll instead of a ranked
+ *     lineup, because a lineup hands selection back to a taste function
+ *     (model or user) and taste functions pick the safest card.
+ *   - CHALLENGERS (6): outside forms from concept-ingredients.json, two from
+ *     each challenger tier (graphic system, instrument language, atmosphere
+ *     world), fused with the product first (challenger supplies form and
+ *     system grammar, product supplies every fact, clarity wins conflicts),
+ *     then weighed against the derived candidates on audience identification
+ *     and product clarity. They win only when they beat the grounded list;
+ *     measured behavior is that they lose to strong cultural material and
+ *     win over thin categories, which is the intended shape.
+ *   - RE-ROLL (--reroll <n>): round n of the same base key. The script
+ *     recomputes what rounds 0..n-1 drew, excludes all of it, and rolls a
+ *     fresh assigned index, challengers, and compositions. One base key therefore
+ *     reproduces the entire chain of rounds.
+ *   - REGISTER (--register safer|bolder): the user's steering on the
+ *     familiar-to-bold axis, applied to a re-roll round. A register changes
+ *     only what this round instructs, never what it dealt: the same key and
+ *     reroll count reproduce the same deal whatever the register, so the
+ *     exclusion chain never forks. bolder presents the dealt foreign forms
+ *     as the whole hand (first-dealt leads, dice-assigned by deal order);
+ *     safer spends the dealt hand unseen and presents the familiar register,
+ *     the model's conventional grounded candidates plus the canon against
+ *     named competitors, the one sanctioned lineup of the model's own list.
+ *     Registers are user-requested, never pre-selected by the model.
+ *   - RATINGS: the reviewer's approval ratings weight the challenger draw
+ *     (3-star doubles the odds, 1-star sits out); the approved pool itself
+ *     is unchanged.
+ *
+ * Usage:
+ *   node scripts/concept-seed.mjs --scope direction --mode persuade
+ *   node scripts/concept-seed.mjs --scope surface --mode operate --from <key>
+ *   node scripts/concept-seed.mjs --scope surface --mode operate --grain flow
+ *   node scripts/concept-seed.mjs --scope direction --candidate-count 6
+ *   node scripts/concept-seed.mjs --scope direction --mode persuade --from <key> --reroll 1
+ *   node scripts/concept-seed.mjs --scope direction --mode persuade --from <key> --reroll 1 --register bolder
+ *   node scripts/concept-seed.mjs --chosen <challenger-id> --kind challenger --from <key> --scope direction
+ *   node scripts/concept-seed.mjs --kind assigned --from <key> --scope direction
+ *
+ * --grain names how much of the product is in play: product, flow, view, or
+ * region. A docs site, an onboarding flow, a landing page and a data table are
+ * four different amounts of product and want different compositions. Grain is a
+ * preference: it deals matching compositions first and tops up from the rest of
+ * the register, and the rendered seed says how many actually matched so a
+ * borrowed structure is never mistaken for a supplied one.
+ *
+ * --platform names the delivery target (web, ios, android). Unlike grain this is
+ * a hard filter: a composition that needs hover or a pointer does not degrade on
+ * a phone, it stops working. --mode also gates which worlds are eligible, for
+ * worlds whose reviewer marked them as carrying only some modes.
+ *
+ * --mode names the requested surface's mode (persuade, operate, read,
+ * experience) so the appended compositions match its register of work; omitted,
+ * they roll from the full approved pool.
+ *
+ * Challenger data resolves in order: a local catalog directory (the private
+ * service repo, evals, and tests set IMPECCABLE_CATALOG_DIR), then the roll
+ * API at impeccable.style, then a degraded assignment-only seed when both are
+ * unavailable. The anonymous choice ping fires once per resolved attended
+ * round on API-dealt rolls: --kind names which card class won (assigned,
+ * pick, challenger, canon) so share metrics have a denominator, --chosen
+ * carries the catalog id when a dealt challenger won, and --register rides
+ * along when the round came from a steered hand. Grounded candidates' names
+ * never leave the machine. DO_NOT_TRACK or IMPECCABLE_NO_TELEMETRY disables
+ * the ping entirely.
+ *
+ * Env vars:
+ *   IMPECCABLE_CONCEPT_SEED — same as --from; for reproducible eval runs.
+ *   IMPECCABLE_CATALOG_DIR  — directory holding the four catalog JSON files.
+ *   IMPECCABLE_API_URL      — roll API base (default https://impeccable.style/api).
+ *   IMPECCABLE_NO_TELEMETRY — disables the choice ping (DO_NOT_TRACK also honored).

+No challengers this run: the roll service was unreachable and no local
+catalog exists. A sandboxed shell without network egress is the most common
+cause; before accepting degradation, rerun this command once through the
+harness's network-enabled or escalated command tool. When that rerun needs
+an approval, state exactly what the approver must know: this script's only
+network contact is one GET to https://impeccable.style/api/roll whose query
+carries scope, mode, an eight-hex seed key, and a re-roll counter; no
+project files, prompts, code, or conversation context are transmitted, and
+nothing is written. An approval request naming that URL and payload judges
+the real action; a bare "run with network" invites rejection for contacting
+an unspecified domain. If the rerun is still refused, proceed with the
+grounded candidates alone; the assignment above still applies at full
+strength. Tell the user plainly that this roll
+ran degraded, with no challengers and no quality-bar boards; do not present
+the outcome as a full roll. A degraded roll changes the cards, not the
+channel: when a browser can open, present the direction on the decision page
+(serve-question.mjs, text-only card); the structured question tool remains

+  --viewport <WxH>    Browser viewport for URL scans (default 1280x800),

+  --no-inline-ignores Do not honor in-file impeccable-disable* ignore comments

+Advisory findings:
+  Some rules are advisory: detected and listed in a separate section, but never

+Project config:
+  Respects .impeccable/config.json and .impeccable/config.local.json detector
+  settings: detector.ignoreRules, detector.ignoreFiles, detector.ignoreValues,
+  and detector.designSystem.enabled.
+
+Inline ignores:
+  In-file comments waive a finding where it lives and travel with the file:
+    <!-- impeccable-disable overused-font -- exported brand doc -->
+    .brand { font-family: Inter } /* impeccable-disable-line overused-font */

+  impeccable-disable applies to the whole file; -line / -next-line are scoped.
+  List one or more rule ids (comma-separated), or omit them / use * for all.
+
+Detection modes:
+  HTML files     Static HTML/CSS analysis (default, catches linked CSS)
+  Non-HTML files Regex pattern matching (CSS, JSX, TSX, etc.)
+  URLs           Puppeteer full browser rendering (auto-detected;

+ * Inline, in-file ignore directives — eslint-disable-style waivers that live at

+ * an ignore in `.impeccable/config.json`.
+ *
+ * A config ignore is the right default for repo-wide policy. This complements it
+ * for the one case config can't cover: a waiver that belongs to a single file and
+ * needs to follow that file when it leaves the repo — a generated/exported
+ * standalone document, an emailed HTML file, a snippet scanned out of context.
+ *
+ * Comment-syntax-agnostic: the directive is a raw token matched anywhere on a
+ * line, so the same marker works across every comment style impeccable scans —
+ * `//`, `/* *\/`, `<!-- -->`, `#`, `{/* *\/}`, `{# #}`. Trailing comment closers
+ * are stripped before the rule list is parsed.
+ *
+ * Syntax (reason optional; eslint `--` or biome `:` separator):
+ *
+ *   impeccable-disable <rule>[, <rule>...] [-- reason]   whole file
+ *   impeccable-disable-line <rule>...      [-- reason]   the same line
+ *   impeccable-disable-next-line <rule>... [-- reason]   the following line
+ *   impeccable-disable                                   bare / `*` = every rule
+ *
+ * Examples:
+ *
+ *   <!-- impeccable-disable overused-font -- exported brand doc, font is first-party -->
+ *   .brand { font-family: Inter; } /* impeccable-disable-line overused-font *\/
+ *   // impeccable-disable-next-line bounce-easing: intentional playful affordance
+ *
+ * Behavior is suppression, for parity with config ignores: a matched directive
+ * drops the finding. The inline reason is self-documenting in the diff; it is not
+ * required and is discarded at scan time (only used here to keep reason words out

+ * The Impeccable hooks command manages the design hook runtime
+ * via the `hook` key and shared detector ignores via the `detector` key in
+ * .impeccable/config.json / .impeccable/config.local.json.
+ *
+ * Usage:
+ *   node hook-admin.mjs status                         # print current state
+ *   node hook-admin.mjs on                             # set enabled: true
+ *   node hook-admin.mjs off                            # set enabled: false
+ *   node hook-admin.mjs ignore-rule <rule-id>          # append to ignoreRules
+ *   node hook-admin.mjs ignore-rule overused-font --all-values
+ *   node hook-admin.mjs ignore-file <glob> [--shared|--local]   # append to ignoreFiles
+ *   node hook-admin.mjs ignore-value <rule> <value>    # append to shared ignoreValues
+ *   node hook-admin.mjs ignore-value <rule> <value> --local
+ *   node hook-admin.mjs ignore-value <rule> "*" --file <glob>   # rule off in <glob> only
+ *   node hook-admin.mjs ignore-value <rule> "*"                 # refused: scope it or use ignore-rule
+ *   node hook-admin.mjs reset                          # remove all config + cache
+ *
+ * Designed to be invoked by the LLM from the reference/hooks.md flow.
+ * Output is human-readable; the harness will pass it back to the user.

+/**
+ * Staleness detection for Impeccable's own project artifacts: PRODUCT.md,

+ * and persisted surface briefs.
+ *
+ * Three kinds of drift live under "out of date", and they want different
+ * handling:
+ *
+ *   1. Tool version drift. The installed skill is older than the published one.
+ *      Owned by computeUpdateDirective in context.mjs, not by this module.
+ *   2. Schema drift. An artifact was written by an older Impeccable: fields it
+ *      no longer reads, fields it now expects, files in retired locations.
+ *      Deterministic, and mostly fixable without asking anyone.
+ *   3. Truth drift. The code moved on and the document no longer describes it.
+ *      Not mechanical. `document` and `init` own the rewrite; the most this
+ *      module does is measure a proxy and name it as a proxy.
+ *
+ * Two tiers, because the boot path runs on every session:
+ *
+ *   Tier 1 (collectBootFindings) spends only what a boot already spends. It
+ *   parses markdown context.mjs has in memory, stats a bounded set of paths,
+ *   and reads the two small JSON files the boot reads anyway. No directory
+ *   walks, no git, no cross-workspace sweep.
+ *
+ *   Tier 2 (the doctor pass) is on demand and may walk, shell out to git, and
+ *   compare declared tokens against real CSS.
+ *
+ * Findings are data, not prose, so both tiers and the JSON output render the
+ * same set. Severity says what should happen, not how bad it is:
+ *
+ *   'auto'    fix it silently the next time that file is written anyway
+ *   'mention' state it once, offer the fix, carry on with the user's task
+ *   'route'   needs a specific command, so name the command and the gap

-/**
- * Browser-side resolution of project detector waivers for Impeccable live mode.
- *
- * The live server serializes `.impeccable/config.json` + `config.local.json`
- * detector ignores (plus the served-root prefixes from the inject config's
- * `files` globs) into `window.__IMPECCABLE_PROJECT_IGNORES__`. This part
- * resolves that config against the current page's URL path when a detect scan
- * starts, so the overlay suppresses the same findings the CLI and the edit
- * hook do (issue #639).
- *
- * Mirrors filterDetectionFindings in cli/lib/impeccable-config.mjs:
- *   1. `ignoreRules` suppress a rule project-wide.
- *   2. `ignoreValues` entries with `value: "*"` suppress their rule in the
- *      files their globs name. The CLI never applies an unscoped wildcard
- *      (isIgnoredFindingValue returns false for it), so neither does this.
- *   3. Remaining `ignoreValues` entries match on the finding's own value;
- *      those are forwarded as `disabledValues` for the detector bundle to
- *      apply where the findings are assembled.
- *   4. `ignoreFiles` globs that name the page waive it wholesale: the
- *      resolver reports `skipScan: true` and the detector answers the scan
- *      with zero findings, mirroring shouldIgnoreDetectionFile in the CLI
- *      and the edit hook's own ignoreFiles gate.
- *
- * `pageFiles`, when the server could resolve it, lists the real project
- * files the inject config serves. A URL that suffix-matches exactly one of
- * them takes that file as its only project identity; an ambiguous or absent
- * match falls back to the served-root common ancestor below.
- *
- * Known gap, unchanged from PR #645: framework apps inject into source files
- * (src/routes/about/+page.svelte) while scans see route URLs (/about), so
- * entries scoped to source or asset paths never match a page candidate and
- * are dropped. That shows the finding, which is the conservative direction.
- *
- * Kept separate from live-browser.js so the glob and page-scope logic can be
- * unit tested in Node (tests/live-browser-ignores.test.mjs) without the full
- * overlay UI bundle.

+ *
+ * Framework knowledge lives in `live/frameworks/` — detection order, adapters,

+ * reads. This file is the CLI around it: resolve config, resolve the
+ * framework, heal orphaned artifacts, apply or remove, record the journal.
+ *
+ * Usage:
+ *   node live-inject.mjs --port PORT [--token TOKEN]  # Insert the live script tag
+ *   node live-inject.mjs --remove                     # Remove the live script tag
+ *   node live-inject.mjs --check                      # Check whether live config exists
+ *
+ * When --token is supplied, it is appended to the /live.js src as `?token=...`
+ * so the server's token-gated /live.js handler will serve the bundle. Omitting
+ * the token yields a bare `/live.js` src (legacy behavior; the server returns

+/**
+ * The live-mode framework registry.
+ *
+ * Before this existed, framework knowledge was smeared across live-inject.mjs
+ * (detection order, the Nuxt adapter, the Astro `is:inline` branch), the two
+ * adapter modules, and live-wrap.mjs (which extension gets component preview,
+ * which gets Astro's global-prefixed CSS, which gets JSX comments). Adding or
+ * fixing a framework meant reading all of them.
+ *
+ * One entry per framework now declares everything the live scripts need:
+ *
+ *   name        stable identifier; also the `adapter` value in inject JSON.
+ *   detect      (cwd, config) → falsy when this is not the project, otherwise
+ *               a truthy project descriptor that apply/remove/artifacts read.
+ *               Order in FRAMEWORKS is priority order; first truthy wins.
+ *   inject      { kind: 'adapter', apply, remove, ignorePatterns, artifacts,
+ *               unpatch } for frameworks that server-render their document
+ *               shell, or { kind: 'tag' } for the generic marker-wrapped
+ *               <script src> block.
+ *   source      how live-wrap treats files this framework authors:
+ *               extensions, preview ('source' | 'component'), styleMode,
+ *               styleTag, commentSyntax, injectScriptAttrs. Anything omitted
+ *               falls back to SOURCE_TRAIT_DEFAULTS.
+ *
+ * Two rules hold the thing together:
+ *
+ * 1. **Detection order is injection priority.** SvelteKit → Nuxt → TanStack
+ *    Start → Astro → Next → Vite → static HTML, exactly the order
+ *    live-inject.mjs used to hard-code. static-html always matches, so
+ *    resolveFramework never returns null.
+ * 2. **Source traits resolve by file extension, not by project.** A SvelteKit
+ *    project's injection target is `src/app.html`; a Vite app can contain
+ *    `.astro` partials. live-wrap has always keyed these off the target file,
+ *    and resolveSourceTraits keeps it that way. Several entries may claim the
+ *    same extension (`.tsx` belongs to three); when they do, the values must
+ *    agree, which tests/live-frameworks.test.mjs asserts.

+ *
+ *   - the dev server is SIGKILLed, so `--remove` never runs;
+ *   - the project changes shape between start and stop (a nuxt.config appears,
+ *     a package.json is edited), so detection resolves a different framework
+ *     and the old framework's artifacts are nobody's business;
+ *   - stop runs from a different directory than start did.
+ *
+ * So every inject records what it wrote to `.impeccable/live/inject-journal.json`
+ * before the next one runs, and both inject and `--remove` reconcile that
+ * record against the tree.
+ *
+ * **The journal is a claim of ownership, not a to-do list.** Healing an
+ * artifact only ever removes what still carries our marker; a generated file
+ * the user has since replaced, or a layout they have since un-patched by hand,
+ * is dropped from the journal untouched.
+ *
+ * **Path resolution is appRoot-relative.** Live entry scripts chdir onto the
