The gate reveals on the first completed pass whatever it found (detection and user-facing behavior: README's Layout issues inbox, Layout issue lifecycle, and Open-time layout gate bullets). Cosmetic, intentional, transient, tiny, warning-severity, and uncertain observations fail open and never enter the inbox. The narrow **fatal** path is separate and still immediate: `/api/:key/artifact-failures` records only `artifact-unavailable` (the chrome's probe of the artifact route failed) or `artifact-asset-unavailable` (the SDK saw a same-origin subresource `error`), marks the session `feedback`, and `takeFeedback` returns them as `artifact_failures`.

The frame bundle (`src/whiteboard-frame.js`, built by `scripts/build.js` into `dist/whiteboard/` with Excalidraw, the converter, React, and vendored fonts) converts the diagram with `@excalidraw/mermaid-to-excalidraw` and mounts the editor; flowchart, sequence, class, ER, and state diagrams become editable shapes with Mermaid node/edge ids preserved (`regenerateIds: false`), and every other diagram type becomes an image the user draws on (`imageFallback`). Frames have no server access: each frame gets a signed, short-lived channel token in its HTML, reports directly to `window.top`, and accepts commands only from that top window; the chrome verifies the token at `POST /api/:key/whiteboard-channel`, binds the frame window and token to its diagram index, then fetches sources (`GET /api/:key/mermaid-sources`, extracted from the artifact file on disk by `src/mermaid-source.js` in `.mermaid` document order) and saved scenes, passes them back over postMessage, and performs all writes. +That channel token is **not** a secret and must never be treated as one: `/whiteboard-frame` has to stay framable by any origin - its legitimate parent is the artifact iframe, whose sandbox gives it an opaque origin that no `frame-ancestors` expression can name - and the frame hands its token to whatever window frames it. Two independent guards carry the trust instead, and both are load-bearing. +Binding: the token is signed over the **session key** (`createWhiteboardChannelToken`/`isValidWhiteboardChannelToken`), so it is a capability for one session only, and `/whiteboard-frame` therefore requires `?key=` and 400s without it; signing `${now}.${nonce}` alone let a token minted with no session named at all authenticate any session. +Descent: the chrome accepts inline whiteboard messages **only from windows whose `parent` is the current artifact frame** (`isArtifactChildWindow` in `src/chrome-client.js`) - descent, not token possession, is what proves the sender is ours; without it, any window that can `postMessage` to the chrome (a popup opener, or a page that framed it) could open a channel and queue a fabricated prompt as the reviewer. Scenes autosave (debounced) through `PUT /api/:key/whiteboard/:index` into per-diagram sidecar files under `<state-dir>/whiteboards/<key>/` (`src/whiteboard-store.js`) - never into `state.json`, which is rewritten wholesale on every store operation; an authenticated `lavish-whiteboard:flush` performs a bounded save before version-driven chrome reloads.

Reopening prompts re-convert vs keep-editing only when the saved scene has preservable edits versus its conversion baseline (`resolveWhiteboardInitAction` in `src/whiteboard-core.js`); an unmodified autosave-on-view silently re-converts. Stale user edits are never silently merged. "Queue feedback" exports the scene and a PNG server-side (`POST .../feedback-files`), then queues a normal prompt with `tag: "whiteboard"` and an `excalidraw-scene` target carrying a bounded edit summary (diffed from the conversion baseline by `summarizeSceneEdits` in `src/whiteboard-core.js` using the stable ids), local `scenePath`/`previewPath`, `sourceHash`, and bounded stats; poll guidance tells the agent to read the summary first and update the Mermaid source, never the scene file.

Upload/delete are same-origin guarded like the whiteboard writes. +The upload route reads the request stream itself via `readAttachmentUploadBody` rather than `express.raw({ limit })`: raw-body aborts on a too-large `Content-Length` WITHOUT draining, which leaves the browser's in-flight upload reset mid-stream so the chip hangs on "uploading" instead of getting the 413. The manual reader buffers up to the cap but always drains to end-of-body, then the route sends a clean 413. Belt-and-suspenders, the chrome also pre-checks byte length against `attachmentMaxBytes` (surfaced in the chrome session JSON) and fails the chip locally before uploading. Do not reintroduce a body-parser `limit` on this route. +Because the sandboxed frame's postMessage source proves origin but not a user gesture, the chrome is the **confused-deputy mediation point**: it rate-limits (`UPLOAD_RATE_MAX`/`UPLOAD_RATE_WINDOW_MS`), enforces a per-chrome-session cumulative-byte quota (`UPLOAD_SESSION_BYTE_QUOTA`), AND bounds concurrent in-flight uploads (`UPLOAD_MAX_IN_FLIGHT`, D8 - rate + cumulative alone let ~30 large bodies fetch at once before the quota tripped) before any upload reaches the loopback server; over-cap uploads are refused with a retry hint and a settled upload frees a slot. The server keeps a bounded default disk quota (`DEFAULT_MAX_ATTACHMENT_DISK_BYTES`) as the durable backstop. +The **trust boundary** is `SessionStore.queuePrompts`: a queued prompt carries only the client's `id` + display `name`; `resolvePromptAttachments` re-derives every authoritative field (absolute `path`, mime, bytes, dimensions) from disk via the injected resolver, so a crafted `/prompts` POST cannot aim an attachment at an arbitrary file. Repeated content ids remain repeated logical references with their own display names and count separately toward prompt count/byte caps; content-addressed storage deduplicates only the bytes on disk. Resolution is **all-or-nothing** (C4): a malformed field/entry, any unknown id, or a count/byte-cap breach rejects the whole batch (`{ rejected, caps }`, persist nothing → 400), never a silent partial-drop; the chrome keeps its queue on the 400 and surfaces the reason. User-facing limits/env vars and defaults are owned by README's Image attachments bullet. +`boundAttachmentRefs` runs BEFORE the resolver and is why a crafted batch can't wedge the server: the in-resolver cap counts RESOLVED refs, and a well-formed id for a file that doesn't exist never advances it, so thousands of them would each buy a sequential `stat` while the store's single mutex is held, stalling every poll and mutation. Raw per-prompt and request-wide (`MAX_REQUEST_ATTACHMENT_REFS`) counts are rejected up front, and the reported rejection list is capped (`MAX_REPORTED_ATTACHMENT_REJECTIONS`) so the 400 can't be turned into an amplifier. New pre-resolve validation belongs in that same pure gate - never after the first `await` into the filesystem. +`SessionStore` owns ONE `AsyncMutex` (`src/async-mutex.js`, `store.lock`) covering BOTH concerns. Every `state.json` read-modify-write runs under it - `queuePrompts`, `takeFeedback`, `recordLayoutWarnings`, `upsertSession`, `endSession`, `addAgentReply` - so a poll can't clear prompts in the window `queuePrompts` holds its pre-resolve snapshot and then clobber the take (E1); **any new store mutation must acquire this lock too**. The server routes its attachment disk sections (upload finalize, delete, the sweep) through `store.runExclusive` so they share that same lock, keeping the reference snapshot + delete atomic against `queuePrompts` (D5). `referencedAttachmentIds` is a pure read and must stay lock-free - the server calls it from inside `runExclusive`, so self-locking would deadlock. Delete is **reference-counted** under the lock - a content-addressed file shared by a queued prompt survives a chip removal (`status: "referenced"`) - and dedup re-upload **refreshes the mtime** so a re-referenced aged file isn't reaped by the next sweep (B3). +Dimensions are persisted at upload in a `<id>.meta` sidecar (D6): `resolveAttachment` reads it instead of re-parsing the whole image, and the thumbnail GET uses `statAttachmentForServe` (one stat + streamed send, mime from the id extension) instead of a second full read. Sidecars are removed with their image on delete/sweep and are excluded from `listAttachments` by `ID_RE`. +The SDK's annotation card gates queuing on BOTH `hasPending()` (R2.4, an in-flight upload) AND `hasErrors()` (W2, a failed/rejected chip) so neither is silently dropped by `collectReady`/`closeCard` - it keeps the card open with a notice so the user can wait, retry, or explicitly remove; that notice line is shared with the card's neutral keyboard hint, so it renders in the error color and is restored (never left stale) once the condition clears. A count-cap rejection remains visible while the card is full and clears only when removing a chip creates capacity. A mixed drop **partial-accepts**: `partitionDroppedFiles` always reports both halves, so the images attach AND every unsupported companion raises its own `UNSUPPORTED_TYPE` chip - reporting the unsupported files only when no image was found is what made a mixed drop swallow them silently. Removing a chip deletes **nothing**: there is deliberately no `lavish:removeAttachment` message and the chrome honors no iframe-driven delete, because the iframe is untrusted and no client can see every live reference (attachments are content-addressed, so another tab's ready-but-unqueued chip shares the id and is invisible from here). Reclamation belongs solely to the reference-aware sweeper; do not reintroduce an eager delete. Upload results are scoped to the document that asked for them: each document mints an `ATTACHMENT_NONCE`, sends it with every upload, and `isTrustedAttachmentResult` requires both an exact nonce match and `event.source === parent` - chip ids restart at `att-1` on every load, so id alone would let a result in flight across a reload mark a new chip with the previous document's image. The card's per-prompt count cap is NOT a literal: `createSdkJs` threads the server's `maxPerPrompt` into the SDK so the local guard matches `LAVISH_AXI_MAX_ATTACHMENTS_PER_PROMPT` (W1), and an over-cap pick is surfaced instantly rather than swallowed. Queued-prompt pills always render at most four thumbnails and collapse every additional attachment into an explicit `+N` badge, independent of that configurable cap (`test/chrome-client-queue.test.js`). The card re-clamps its viewport position after every attachment-row render (W3) so chip rows can't push Queue/Cancel off-frame; the chip list also has a `max-height`/scroll backstop. +Cleanup (`sweepAttachments`, run at server startup + hourly) is **reference-aware**: a file is reaped only when it is both past its TTL AND not in `SessionStore.referencedAttachmentIds()`, and the disk cap only ever evicts unreferenced files older than `ATTACHMENT_EVICTION_GRACE_MS` - so a send-and-end batch's images are never lost before delivery, and orphaned uploads (card cancelled, or `/prompts` never followed) are reaped later. +That reference set is pending-prompt ids **plus** ids delivered within `ATTACHMENT_DELIVERY_GRACE_MS`: `takeFeedback` clears the delivered prompts, so without that window an attachment would become sweepable at the exact moment the agent starts reading the path it was just handed. The grace is a bounded read window, not a second lifetime (the TTL and disk cap must still reclaim delivered bytes eventually), and the retained list is capped (`MAX_DELIVERED_ATTACHMENTS`) because it lives in `state.json`, which is rewritten wholesale on every store operation. +The eviction grace is the symmetric window on the upload side (fixed, not env-tunable): "unreferenced" also describes a **ready card** - an image sitting in an open annotation card that has not queued a prompt yet - so cap eviction with no age floor deletes bytes out from under the imminent Send, which then fails unrecoverably as not-found. It never lets the total exceed the cap, because admission refuses the new write instead. +The disk cap charges **allocated** cost, not logical image bytes: `listAttachments` reports `chargedBytes` = the image rounded up to whole `ATTACHMENT_ALLOC_BLOCK_BYTES` (4096) blocks plus the sidecar's own block, and both of its enforcement points measure `maxDiskBytes` against that accounting. Summing logical `size` let a flood of 12-byte magic-prefix uploads (the smallest `detectImageType` accepts) sit ~683x under the reported total while consuming real disk and inodes. +The periodic sweep is only one of those two points, and it can never hold the cap alone: it refuses to evict referenced or in-grace files, so concurrent chrome pages could each write past `maxDiskBytes` in the window before the next sweep. `admitAttachmentCharge` inside `writeAttachment` is therefore the single **upload-admission chokepoint** every byte-adding write path must route its charge through (today a new image+sidecar and the dedup sidecar repair; the dedup mtime rewrite replaces identical bytes and the sweep only removes): it reclaims toward `cap - newCharge`, measures the true committed allocation with its own tree walk so the undeletable temp/orphan debris a curated survivor set hides is still counted, and refuses with **507** when the write would not fit. Admission must run under the store's lifecycle lock so the reference snapshot, the reclaim, and the write are one critical section; a refused sidecar repair is skipped (the sidecar is only a display cache) rather than failing the dedup upload. The `maxObjects` bound is **derived** from the disk budget (`budget / 2 blocks`), never a separate env var, so it can only agree with the byte cap. The sweep's cap/object eviction keeps **running totals** decremented per removal rather than recomputing over all survivors per candidate: it runs under the store's global mutex, so per-candidate O(n) work would be an E3-class lock hazard. The sweep also reaps files that `ID_RE` hides from every cap: crash-orphaned temp files (D6) — `writeFileAtomically` writes `<name>.<pid>.<n>.tmp` then renames, and a crash in between leaves one, reaped once older than a 5-minute grace (a live write renames within ms) — and orphan `<id>.meta` sidecars whose image is gone (ATTACH-002), reaped with no grace since a live upload writes the image before its sidecar. `removeAttachment`/`removeFile` delete the sidecar FIRST, so a crash between the two removals leaves only the counted image, never an uncounted orphan sidecar. The SDK decides a whole drop in one pass via the pure `classifyAttachmentBatch` (mime / size / count-cap per file) and `addFiles` renders **once** instead of per file (D7 - a large multi-drop was O(N²) DOM rebuilds); `rejectUnsupportedBatch` does the same for unsupported files. The size decision lives in that classifier and still runs **before** `createObjectURL`/`arrayBuffer` (`attachmentSizeError`, threaded from the server via `createSdkJs`'s `maxAttachmentBytes`), so an oversized drop is decided `error` and never read into a buffer or structured-cloned into the chrome; the server still re-checks. +Attachment files and dirs are created **owner-only** (`0600`/`0700`, set explicitly at creation since the umask would otherwise leave 0644 in traversable dirs) and `ensureAttachmentDir` re-asserts the dir modes so an install that uploaded before that hardening doesn't keep its existing screenshots exposed. A dedup upload's mtime refresh is load-bearing (it restarts the TTL clock) and must never be swallowed into a success: `writeAttachment` falls back to an atomic rewrite of the identical bytes and propagates if that fails too. Env limits floor BEFORE the bounds check and require `>= 1`, so a fractional `0.5` falls back instead of flooring to a silent zero cap; only `0`/`off` may disable one. + ### Export (local-asset inlining) `src/export-bundle.js` (`buildSelfContainedHtml`) inlines only an artifact's **local** assets: local stylesheets/classic scripts become inline `<style>`/`<script>`, and local images/fonts/icons, confined fetchable `file://` refs, and CSS `url(...)`/`@import` become data URIs (recursively, resolved relative to each stylesheet). @@ -126,7 +153,7 @@ Absolute `file://` paths in non-inlined regions are redacted to `about:blank` so The transform records `warnings` rather than failing, split into unresolved local assets (such as `load-failed`, `outside-root`, `too-large`, or unsupported local references left external) and notices (such as `csp-meta` or `file-url-redacted`).

Keep the font-load and second-conversion ordering in `convertExcalidrawSkeletonsAfterFontsLoad`, and keep the versioned saved-scene repair expansion-only so it never overwrites user geometry or content. The real-browser regression in `test/whiteboard-render.browser.test.js` covers both paths. + - Mermaid node labels use `<br>` / `<br/>` and a two-character `\n` as line breaks. `parseMermaidToExcalidraw` copies `vertex.text` onto skeleton `label.text` unchanged, so those markers stay literal characters and Excalidraw concatenates "classify<br>checks" into one line. `restoreMermaidLabelLineBreaks` in `src/whiteboard-core.js` must run on skeletons before `convertToExcalidrawElements` (and again on materialized text with a measure pass) so Excalidraw `text` / `originalText` get real `\n` and the box sizes to the line set. When that pass grows a node-label container (rectangle, ellipse, diamond) from the center, it must also reposition the independently stored bound-text `x`/`y` into the new box; skip labelled arrows, whose labels sit at path midpoints. `convertSource` mounts without `restore()`, so Excalidraw will not re-derive that geometry on first paint. `test/whiteboard-core.test.js` and the clipping browser fixture cover both break forms, the fusion case, bound-text recentering, and labelled-arrow skip. - The converter breaks with mermaid >= 11.14.0: its parsers reach into mermaid's rendered DOM/db internals, and newer versions silently degrade class/ER/state diagrams and subgraph flowcharts to image fallbacks. `mermaid` is pinned EXACTLY (independent of the artifact-facing Mermaid CDN version in `src/design-reference.js`), and `test/whiteboard-pins.test.js` fails any unpinning; bumping requires a live re-probe of native conversion. - Excalidraw's theme must be passed only through the `<Excalidraw theme>` prop, and persisted `appState` must never carry `theme` or a dark-space `viewBackgroundColor`: dark mode renders through an invert filter, so a dark background value or a second theme application double-inverts into a washed-out canvas (`src/whiteboard-core.js` strips both at the persistence boundary). - `/whiteboard-assets/*` must keep `Access-Control-Allow-Origin: *` (the opaque-origin frame's font fetches are CORS-gated), `Cache-Control: no-cache` (an unversioned bundle URL plus memory cache serves stale editors after upgrades), and `dotfiles: "allow"` in sendFile (a checkout under a dot-directory otherwise 403s every asset). + - A sidecar's presence is not a user edit: `startFromConversion` autosaves on view, including scroll/zoom from fit-to-content. `handleInit` must go through `resolveWhiteboardInitAction` so a Mermaid-source change silently re-converts an unmodified-since-conversion scene and only prompts when `savedSceneHasPreservableEdits` finds preservable edits.

Agent-initiated ends keep reopening normally, same as before. `lavish-axi poll`'s `ended` response and the `feedback` response for the final batch before an end both carry `next_step` guidance telling the agent to stop polling and deliver remaining updates in chat instead of reopening. -- **Precise targets** - Text annotations include selected text plus range anchors, so agents are not limited to whole-element selectors. +- **Precise targets** - Text annotations include selected text plus range anchors, and text selections carry those anchors only. + Clicking an element inside a table also carries the cell's visible row and column names alongside the exact CSS locator, so filtered or sorted rows do not make feedback look misdirected. + When merged cells make either name ambiguous, Lavish leaves that name out rather than guessing; an explicit `<th scope="row">` remains authoritative even when a `rowspan` makes the row's position ambiguous. + The CSS locator still points at the exact element you clicked, so an annotation with an omitted name is only less descriptive, never mislabelled. +- **Image attachments** - Attach reference images (PNG, JPEG, WebP) to an annotation by pasting, drag-dropping, or using the annotation card's **Attach image** picker; each shows a thumbnail chip with upload, remove, retry, and error states. + Images are stored under the state dir and the queued prompt carries a server-generated absolute `path` and content-hash `id` (plus mime and dimensions) - never the raw bytes - so `lavish-axi poll` hands the agent a local file path to open. + Limits are `LAVISH_AXI_MAX_ATTACHMENT_BYTES` (default 10 MiB per image), `LAVISH_AXI_MAX_ATTACHMENTS_PER_PROMPT` (default 4), and `LAVISH_AXI_MAX_PROMPT_ATTACHMENT_BYTES` (default 25 MiB per annotation); if any image is missing or any annotation breaches a count or byte cap, the entire send batch is rejected, the queue is preserved, and the reason is surfaced in the composer rather than silently dropping images. + As a browser-side abuse guard, each chrome page allows 30 upload attempts per rolling minute, 4 uploads in flight at once, and 256 MiB of attempted image bytes over its lifetime; rejected uploads stay visible on their annotation card for retry or removal. + Attachments are cleaned up by `LAVISH_AXI_ATTACHMENT_TTL_MS` (default 7 days; `0`/`off` disables) but only once no pending prompt still references them; `LAVISH_AXI_MAX_ATTACHMENT_DISK_MB` (default 512 MiB; `0`/`off` disables) caps total attachment disk. + The cap is enforced when an image is uploaded, not just periodically: the upload first reclaims unreferenced files (oldest first, and never one added within the last hour), and if it still would not fit, that upload is refused with a storage-full error on its chip instead of discarding an image an annotation is about to send. - **Mermaid diagrams** - In the Lavish browser, every rendered Mermaid diagram in a `.mermaid` container becomes an embedded editable Excalidraw whiteboard.
