PDF export now emits selectable + searchable PDF text on top of the
threaded-frame raster, the same way the existing reflow-entry path
does. Result: text in threaded frames is searchable in any PDF
viewer, copy-pasteable, and accessibility-tree-visible — not just
pixels.
What changed:
- _drawFrameLinesToCanvas accepts optional textOps + fontWarnings
args. When provided, each rendered line gets pushed as a textOp
describing {text, fontKey, sizePt, color, align, leftIn, widthIn,
topInchesFromTrim}. Unsupported font families (anything outside
pdf-lib's standard 14) are collected into fontWarnings.
- Empty / whitespace-only lines skipped (no glyphs to emit).
- renderBookDesignedPageToCanvas accepts textOps + fontWarnings and
threads them to _drawFrameLinesToCanvas.
- exportBookToPdf populates textOps for designed pages too — same
pattern the reflow branch already used. The existing pdf-lib
drawText loop after the PNG embed handles both paths since the
op shape is identical.
Limitations:
- Bold / italic per-line not yet supported — typography stores
family + size + color + alignment + line-height + paragraph gap,
but not weight or style flags. Adding weight: 'bold' / italic to
the typography schema is a small follow-up.
- Only the 14 standard PDF fonts get real-text emission. Custom
families fall back to raster-only (with a fontWarning surfaced
in the export status).

Two stragglers from the migration commit:
- _bookPortOnClick read layer.nextFrame?.frameId to decide whether
the click should break a thread. Now reads from the thread
collection via _findThreadForFrame + _frameIndexInThread.
- The out-port tooltip read layer.nextFrame.frameId for the
'⌗xxxxxx' destination hint. Switched to the pre-computed nextRef
variable (already derived from threads[] earlier in the function).
- addBookTextFrame no longer initializes 'nextFrame: null' on new
layers — that field is gone. Thread membership comes from
book.threads[]; new frames are solo until linked.
After this sweep, no runtime code path reads layer.nextFrame. Only
the one-time migrator still touches it (intentional — it converts
legacy inline data into the collection then deletes the field).

Source of truth for thread topology is now book.threads[] — a
top-level collection on the book manifest. Each thread:
{ id, sourceChapter, frames: [{ target, frameId }, ...] }
Layers no longer carry layer.nextFrame or layer.sourceChapter; the
thread collection is the canonical store. Aligns with the spec's
'events as linked files' model: thread graphs live in the manifest,
visible to the recipient, round-trippable.
What changed:
- New thread API: setFrameOutgoing, clearFrameOutgoing,
setFrameSourceChapter, _findThreadForFrame, _frameIndexInThread.
All write helpers handle the rebalancing dance (splitting threads,
re-stitching, dropping empty single-frame threads).
- One-time migrator migrateBookThreadingToCollection — runs from
ensureBookState on every state restore. Idempotent. Converts any
legacy inline nextFrame / sourceChapter into book.threads[] then
deletes the inline fields. Existing books migrate transparently
the first time they're opened after the upgrade.
- _bookCollectThreadChain: now reads thread directly from
book.threads[]. The backward / forward walk over inline links is
gone — much simpler.
- _bookFrameChainContains: same — reads from threads.
- All readers updated to ask threads[] for the answer:
_attachBookFramePorts (link state + chip), the editor canvas text
painter, the tile thumbnail / PDF canvas pipeline, the Chapters
tab Place button + Place helper, the inspector dropdowns +
diagnostic status.
- All writers updated to call the new helpers instead of writing
to layer.nextFrame / layer.sourceChapter:
_completeBookPortLink → setFrameOutgoing
_breakBookFrameLink → clearFrameOutgoing
inspector outgoing dropdown → setFrameOutgoing / clearFrameOutgoing
inspector incoming dropdown → clearFrameOutgoing on old + setFrameOutgoing for new
inspector chapter dropdown → setFrameSourceChapter
Chapters-tab Place button + _placeChapterIntoSelectedFrame
chip × clear button → setFrameSourceChapter(null)
- bookManifestPayload + bookPayload (whole-book JSON) include
threads[]. Load path restores them.
The migrator + dual support means: legacy books in autosave/JSON/
Nostr round-trip cleanly. New writes go straight to threads[].
Cleaner manifest schema, smaller layer payloads, and the right
shape before merging to main.

Two paired improvements:
1. Pages-overview tile thumbnails now render at 144 dpi instead of
72. At typical grid widths (~150 px tiles) the 72 dpi raster
shrank text to ~3 px tall — illegible. 144 dpi quadruples the
pixel count per tile (~16 ms → ~60 ms per tile on the work I
profiled informally) but text becomes readable. A content-hash
cache is the next perf step if grids get large.
2. Text-frame typography is now per-frame, not per-thread. Each
frame in the chain can override font / size / line-height /
alignment / color / paragraph gap. The head's typography is the
fallback when a frame doesn't set its own.
- _paginateParagraphsIntoFrames reads typography fresh on every
frame advance (and at paragraph start) so size differences flow
correctly — when text crosses into a 14pt frame from a 10pt
frame, line heights adjust mid-flow.
- Painters (_paintFrameLines DOM + _drawFrameLinesToCanvas
canvas) receive each frame's own typography rather than the
head's.
- Inspector typography controls are now editable on every frame
(not just the head). Writes go to layer.typography on the
selected frame. The status hint distinguishes head ('Applies
to this frame. The head\\'s typography is also the chain\\'s
fallback.') from mid-thread ('Applies to this frame only —
overrides the head\\'s default.').
Known limitation: when a paragraph spills across a typography
boundary, the spilled lines were wrapped at the source frame's
width. They place + render at the destination's typography but
keep the source frame's line breaks. Re-wrap-on-advance is J4.d.3.

The floating bar (Back · Publish · Proof PDF · Cover JSON etc) sits
absolute at top:10px and overlapped the top edge of the sheet
underneath. Added 60px top padding to .previewShell when the bar is
visible (editing-book-page OR editing-book-cover) so the sheet lands
below the bar.
Both @media print and body.exporting revert the padding back to the
24px default AND hide the bar entirely, so canvas exports and
browser-print outputs aren't offset by the on-screen clearance.

_bookCollectThreadChain shared a single 'seen' set between the
backward and forward walks. For a chain A → B → C started from C,
the backward walk visited B then A, leaving seen = {B.id, A.id}.
The forward walk from head A then tried to push B, but found B in
seen and broke immediately — returning chain [A] instead of
[A, B, C].
Symptom: cross-page flow worked for any 2-frame chain (forward
walk only had one node to visit), but broke as soon as the chain
hit 3 frames. The user repro 'A on page 1 → B on page 1 → C on
page 2 doesn't flow' matched exactly.
Fix: use separate seen sets per walk direction. Each starts with
the relevant endpoint (layer for backward, head for forward) and
detects same-direction cycles without bleeding into the other.
Affects every consumer of _bookCollectThreadChain: editor canvas
text rendering (_attachBookFramePorts), tile thumbnails
(renderBookDesignedPageToCanvas via the J4.c.2 hook), PDF export
(same path), and the text-frame inspector's chain / line-count
diagnostic.

When a text-frame is selected in a thread, the status line now shows
the actual paginator output:
Frame 2 of 3 in this thread · 12 lines here; chain: [18 · 12 · 5]
That makes it obvious whether the chain walk found every frame and
how many lines landed in each. If the chain shows length 2 when the
user expects 3, the chain walk dropped a frame (probably a stale
nextFrame ref). If the chain looks right but line counts are wrong
in the 3rd frame, the bug is in the paginator.
Also logs a console.warn + appends '⚠ outgoing link is broken' to
the status when this frame's outgoing nextFrame ref points at a
frameId that doesn't exist in state.layers (deleted frame /
deleted page).
Diagnostic-only — no behavior change. Helps pin down the
'cross-page flow stops after 2 frames' bug.

Replaces the DOM-based preview helper for designed-page tiles with
renderBookDesignedPageToCanvas at 72 dpi. That's the SAME function
the PDF export + Reader Mode use, so the tile is guaranteed to
match the print output. No more drift on:
- Linked-design layers (async resolve was inconsistent in the DOM
preview path)
- z-order between threaded text and overlapping layers
- Clip paths (DOM preview used a different clip serialiser)
- Group transforms
- Master text-frame outlines (already filtered in J6, but worth
noting they're handled by the canvas path too)
- Master layer underlay z-ordering
- Token substitution in master text (canvas path runs
applyBookTokensToLayers)
Each tile:
- Stage 1 (sync): paint the spec background colour so the grid
doesn't shift while canvases render.
- Stage 2 (async): renderBookDesignedPageToCanvas → canvas.toDataURL
→ swap in as <img>. Guarded by isConnected so late completions
don't overwrite a re-rendered tile.
Trade-off: each tile spins up its own async render. For typical
book sizes (10-100 pages) this is fast enough. A future cache by
(entry.id + content-hash) could skip re-rasterising unchanged
pages on every grid repaint.
The old _paintThreadedFramesOnThumb helper is now dead code
(canvas renderer handles threaded text internally) but left in
place; cleanup deferred.

Adds an InDesign-style 'Links panel' to the book's Document settings
modal — every external event the book references, with status.
Each row shows:
- Icon (🏷 cover · 🎨 master · 📐 page · 📄 chapter · 📚 manifest)
- Label + truncated coord (kind:pubkey…:dTag)
- Status pill:
resolved — sidecar data is in state (layers loaded / markdown
fetched)
🔒 private — encrypted ref (decrypt happens at resolve time)
unresolved — ref set but no data fetched yet (try Refresh)
unpublished — surface has layers but no Nostr ref (publish to
mint an event)
local draft / empty — chapter content without a ref
- Actions: 📋 copy naddr to clipboard · ↻ force re-fetch this
sidecar via resolveBookSidecars(..., { force: true })
Plus a 'Refresh all' button under the list that forces a full
re-resolve and repaints the panel when done.
Counts shown in the section header summary so you can see at a
glance how many references are resolved vs. pending.
Closes the loop on the Manifest Links design the user asked for —
this is the read-only view of what the casewrap-book event points
at, alongside the chip / refresh affordances that have been on the
sidebar and tile rows since D1.7.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
Closes the loop on the manifest pattern. Two new buttons in the
book sidebar:
- 📥 Import book from Nostr… — paste an naddr / nevent at a
casewrap-book event. The function resolves the event, tries
NIP-44 / NIP-04 decryption (so private books work), feeds the
payload through loadProjectFromText's existing book branch,
injects the publish ref so future Publish replaces in place,
then surfaces resolveBookSidecars summary (X / Y resolved, N
failed) into #bookResolveStatus when it settles.
- 📁 Import book from JSON… — file picker that accepts the
whole-book JSON Save Project writes (templateMode='book' +
top-level book field). Same downstream path as Nostr import;
also kicks off the resolver so any chapter-by-textRef refs
populate.
Both reuse the existing book branch of loadProjectFromText (line
30441) — no new state-restore code; just clearer entry points for
discovery. Community-browser-driven loads still work; this is the
direct-paste / direct-file affordance the user couldn't find before.
Status reporting comes through #bookResolveStatus (the hint line
that already shows '↻ Refresh from Nostr' results) so users can
see progress without opening DevTools.

Three causes of inaccuracy in the thumbnail rendering, all addressed:
1. Bleed offset. Layer x/y are stored sheet-relative (include bleed
inches). The tile canvas is sized trim-only (matches what gets
printed). Result: every layer rendered shifted right + down by
bleed/trim ≈ 2% for US Trade. Now offset each layer by -bleed when
composing the tile preview — same translation
renderBookDesignedPageToCanvas uses for PDF export.
2. Text-frame outlines. The dashed text-frame border is an authoring
affordance, not a print element. The designed-page tile path now
filters out shape layers with kind='text-frame' before passing to
the preview helper (same filter the reflow-tile path already used
on masters). Threaded chapter text still paints over the bare
frame area via _paintThreadedFramesOnThumb.
3. Aspect ratio. Tiles defaulted to 2:3 in CSS — fine for US Trade
6×9 but distorted for Square 8×8, A4, etc. Each tile now sets
aspect-ratio inline from the book's actual trim dimensions.
Tiles should now match the PDF output much more closely.

Two architectural shifts to match how design tools (InDesign, Affinity
Publisher, Scribus) handle threaded text.
1. Content vs presentation split. Chapter markdown is flattened to
plain paragraphs on import — headings, bold, italics, list
bullets, blockquote marks all stripped. The author writes in
markdown because it's a good authoring format; the designer
applies presentation on the frame, not in the source.
2. Line-by-line spill. The block-based engine moved whole paragraphs
to the next frame when they didn't fit, leaving gaps at the
bottom of each frame. The new engine wraps each paragraph against
the current frame's width using its typography, then places
lines one at a time — when the frame is full, the NEXT line
continues in the next frame. Paragraphs break across frames
gracefully.
What changed:
- _flattenChapterToParagraphs(md) strips markdown to plain text,
collapsing whitespace and preserving paragraph breaks.
- _getFrameTypography(layer) returns the frame's typography (font,
size, line height, alignment, color, paragraph spacing) with sane
defaults.
- _paginateParagraphsIntoFrames(paragraphs, chain, typography) is
the new line-based paginator. Wraps each paragraph using the
active frame's inner width, fills the frame to height, advances
to the next frame, repeats. Returns per-frame line buckets +
hasMoreText flag for overset detection.
- _paintFrameLines / _drawFrameLinesToCanvas — DOM + Canvas2D
rasterisers for the new format. Replace _paintFrameBlocks and
_drawFrameBlocksToCanvas in the three render paths (editor,
tile thumbnails, PDF export).
- addBookTextFrame seeds new frames with default typography
(Georgia 11pt, 1.5 line-height, 0.1in paragraph gap, left align,
near-black).
- Text-frame inspector adds a 'Typography' section: font, size,
color, line height, paragraph spacing, alignment. Editing on
the head propagates to the whole thread. Mid-thread frames show
the read-only inherited values.
Existing reflow entries (chapters in book.pages used the
non-threaded way) still flow through the legacy block engine —
that path is untouched.

Replaces the port-click dance as the primary path for threading +
chapter placement. Whenever a text-frame layer is the primary
selection in book mode, a new #bookTextFrameOptions section appears
in the right-side #toolOptions panel with:
- Status line: 'Frame N of M in this thread' / 'Solo frame' /
'(Head — chapter source goes here)'.
- Chapter source dropdown — every reflow entry in book.pages. Only
enabled when the selected frame is the head of its thread;
mid-thread frames inherit and show a hint to that effect.
- Incoming-from dropdown — every other text frame in the book that
could safely link TO this one (no cycle). Selecting one sets the
source frame's nextFrame to point here; selecting (none) clears
whatever was linking in.
- Outgoing-to dropdown — every other text frame this one could
safely link to. Selecting one sets this frame's nextFrame;
selecting (none) breaks the link.
Both dropdowns share _enumerateBookTextFrames, which labels each
candidate by its surface ('Page 3', 'Master · Standard interior') +
its ⌗frameId. Cycle detection reuses _bookFrameChainContains so the
dropdown only shows safe candidates.
Force-shows the outer #toolOptions panel when the inspector is
visible — the default toggling in syncToolPaletteUI hides it for
the Select tool, but with a text-frame selected we want the
inspector regardless of active tool.
Port-click + Chapters-tab 'Place' button still work as alternative
paths. The dropdown panel is the discoverable one.

Three reported bugs, one root cause: the in/out ports sat at the
top-left and bottom-right CORNERS of every text-frame layer —
exactly where the lh-nw and lh-se resize handles live — AND their
pointerdown bubbled to the freeLayer's startLayerDrag handler.
Symptoms:
- Couldn't resize a text frame (corner handles hidden under the
larger-z-index ports).
- Couldn't click an in/out port to thread (the port's pointerdown
started a layer drag, the click never fired).
- Couldn't 'Place chapter into selected frame' (the chapter button
needs a selected frame, and selection requires a click that
wasn't being shadowed by drag).
Fixes:
- Move ports OUTSIDE the layer's bounding box on the top edge
(in port) and bottom edge (out port), centered. New tab shape
with a dashed connector to the frame edge so the affordance
reads. Both well clear of the 8 corner/edge/rotation handles.
- Bump the frameId badge to sit just above the layer (top-right,
-16px) so it doesn't visually conflict with the in port.
- Add pointerdown + mousedown handlers on both ports AND on the
source-chapter chip + its X clear button that stopPropagation.
Drag handler no longer kidnaps the click.
Resize, select, link, and place-chapter all flow correctly now.

Reader Mode reuses renderBookDesignedPageToCanvas, which the J4.c.2
commit already updated to render threaded chapter text. So J4.c.3
is implicit — no code change needed beyond what J4.c.2 shipped.
Adds an 'Implementation status' table to the spec so anyone reading
the doc later can map phase labels to actual commits + see what
still pends.

renderBookDesignedPageToCanvas now walks page layers after the
master + page layers are drawn, finds text frames whose thread head
holds a placed chapter, paginates via _paginateChapterIntoThread,
and rasterises each frame's slice onto the export canvas at the
frame's coordinates.
New helper _drawFrameBlocksToCanvas — stripped-down counterpart to
the block-painting loop in renderBookReflowPhysicalPageToCanvas.
Handles paragraphs, headings, lists, blockquotes, code blocks, hr,
and plain text — same things the editor's _paintFrameBlocks paints
to DOM. Tables in threaded frames + real-PDF textOps emission (for
selectable text in the PDF) are deferred to a J4.b2 cleanup.
PDF output should now contain the threaded chapter text where the
user authored their frames, not just the dashed text-frame outline.

After a designed-page tile is painted, walk its text-frame layers,
identify any that hold a placed chapter via their thread chain, and
paint each frame's paginated slice as an overlay at the frame's
position in the thumb canvas. Same _paintFrameBlocks helper the
editor uses, sized to the frame's bounding box.
The tile thumbnail now reflects the real text flow — author a
chapter, place it on a page-1 head frame, and the Pages overview
shows the first chunk of the chapter text in that frame; the
linked frame on page 2 shows the next chunk.
Still pending: PDF export and Reader Mode walk reflow entries the
old way (J4.c.2 / J4.c.3).

Lets a thread have frames of different sizes and have text wrap
correctly in each. The chain {frame1: 6×4, frame2: 4×6, frame3:
6×6} now line-breaks at frame1's 6″ width, then at frame2's 4″
width, then at frame3's 6″ width — no clipping in the narrow
frame, no excess gutter in the wide one.
What changed:
- paginateChapter accepts opts.startTokenIndex and opts.maxPages.
The token loop honors both: starts from the given index, stops
after the page count is met, and returns result.endTokenIndex
so the caller knows where to resume.
- _paginateChapterIntoThread walks the chain frame-by-frame,
calling paginateChapter once per frame with that frame's
geometry + the running token cursor. Each frame contributes its
own one page to the chain.
- Overset detection switched from a page-count comparison to a
token-cursor comparison (paginated.hasMoreText). More accurate
with variable geometry where page count ≠ frame count.
Limitations still standing:
- PDF export, Reader Mode, and tile thumbnails still walk
book.pages reflow entries the old way — J4.c.
- Tokens are re-lexed and re-measured per frame today. For long
chains this is N × token-count work; cache by chain+chapter
if it becomes a perf problem.

Hooks up the threading wiring so chapter text actually pours through
the frame chain you authored in J3 + J5.
What changed:
- paginateChapter now accepts opts.frameOverride = { x, y, w, h,
padding }. When provided, it skips the master-frame lookup and
uses the override directly. Existing callers (master-driven
pagination) keep working unchanged because the override is opt-in.
- New _paginateChapterIntoThread(headLayer, book) — builds a
synthetic call to paginateChapter using the head frame's geometry,
returns the pages + the resolved chain.
- New _paintFrameBlocks(el, page, frameW, frameH, padding) — paints
one paginated page directly into a freeLayer wrapper. Like
paintReflowPageOverlay but coordinates are frame-local instead of
page-local.
- In _attachBookFramePorts: when a chip is being shown (chapter
placed on the thread's head), paginate + paint the slice for THIS
frame. If the chapter overruns the chain, the last frame gets a
red ⊞ OVERSET badge. If the chapter is shorter than the chain,
extra frames get a muted '(thread continues — chapter ended
upstream)' placeholder.
You can now: thread frames, place a chapter on the head, and the
text actually flows across the chain. Real text, real wrapping,
real headings + lists + code blocks — same layout engine the
reflow-entry path has always used.
Limitation captured for J4.b: every frame in a thread shares the
head's geometry. Variable-geometry threads (e.g. front-matter frame
narrower than body frames) need the engine to walk tokens per-frame
instead of all at once. Today the line breaks are computed once at
head geometry and re-used.
PDF export, Reader Mode, and the per-tile thumbnail painter still
walk book.pages reflow entries the old way — they don't see threaded
frames yet. That's the J4.c cleanup once the engine settles.

Wires a text-frame layer to a chapter source. UX:
- Each chapter row in the Chapters tab gets a '📥 Place in selected
frame' button. Disabled when no text-frame is selected, when the
selected frame is mid-thread (must place on the head), or when the
selected frame already holds this chapter.
- On click: head.sourceChapter = entry.id, history-push, re-render.
- Threaded text frames render a small blue chip up top showing
'📄 <chapter title> · frame N / M', plus an × button on the head
to unplace. The chip is identical across every frame in the chain
so the chapter assignment is legible everywhere.
- Inside the frame: italic placeholder line ('(text will flow here
— J4 pours it)'). Real text layout into per-frame geometry lands
in J4.
The thread-walk uses _bookCollectThreadChain, so a placed chapter
is visible across all linked frames immediately. Unplacing from the
head clears it everywhere in the chain.
Mid-thread frames don't get a clear button — clearing on a non-head
would be ambiguous. The Chapters tab button refuses to place on a
mid-thread frame for the same reason.

Hovering any in / out port of a threaded frame highlights every
frame in the same chain. The head of the thread (first frame, no
incoming link) gets a blue outline; the rest get green. Hover off
clears the highlight.
_bookCollectThreadChain walks backwards along incoming nextFrame
refs to the head, then forward along outgoing refs to the tail.
Cycle-safe and depth-capped. Makes long threads (e.g., a chapter
flowing across many designed pages) immediately legible — useful
in J5+ when threads start spanning more than two frames.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
Wires the in/out ports added in J3.a. Workflow:
- Click an empty out port → enters 'loading' state (cursor turns to
copy, body gets .book-port-loading, source port pulses, every
empty in port highlights as a drop target).
- Click another frame's in port → links them. sourceLayer.nextFrame =
{ target, frameId }. Toast confirms.
- Click an already-linked out port → breaks the thread at that point.
- Click the same source out port again, or press Esc → cancels.
- A cycle guard refuses links that would close a loop (A → B → C,
then trying C → A).
Pure data updates so far — no rendering change to the chapter
content. The pagination engine still uses the master-frame-clone
model from C4. J4 swaps in a thread-walking pagination engine that
honours these nextFrame refs.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
First step of the threading UI. Every text-frame layer in book mode
now shows:
- An 'in' port (small square, top-left corner) — turns green when
another frame's nextFrame ref points at this one.
- An 'out' port (small square, bottom-right corner) — turns green
when this frame's nextFrame points somewhere.
- A tiny '⌗ <frameId>' badge in the bottom-left so the user can see
the frame's stable id while authoring.
Reads thread-link state from layer.nextFrame on each frame (no
book.threads[] consumer yet — that lands in J4 with the pagination
refactor). Legacy text-frame layers (created pre-J2) get a frameId
backfilled the first time they render, so old books gain the new
ports automatically.
Click handling is not yet wired — J3.b adds the load-cursor + link
flow. The ports are visible affordances and tooltips today.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
Generalises the text-frame layer from master-only (Phase C4) to any
book surface. Designed pages can now host text frames the same way
masters do, with the same '+ Text frame' button in the page-edit
bar.
What changed:
- addBookTextFrameToActiveMaster() → addBookTextFrame(targetOverride)
that picks up book.editingMasterId OR book.editingEntryId depending
on which surface is open. Legacy alias kept so old callers don't
break.
- New layer carries a stable frameId (independent of layer.id) and
a nextFrame field (null for now; J3 will use it for threading).
- bookMasterAddTextFrame button now visible in both master-edit
AND page-edit modes. Title updated to read 'a text frame to this
surface (master or designed page)'.
- Click handler now calls the generalized addBookTextFrame().
The frame still renders as the existing dashed-blue text-frame
shape with no content of its own — pagination still flows chapter
text through master frames as before. J3 wires the in/out ports
and the click-to-link UX; J4 makes the pagination engine walk
thread.frames[] instead of cloning masters.

The starter-template panel fired on '!pages.length' which is now
ambiguous: a user can have chapters (counted in pages[]) but no
designed pages, and the Pages tab needs to say something. Splits
into three cases:
(1) no designed pages AND no chapters → starter templates (as
before, with the hint updated to point at the new Chapters tab
for + Add chapter)
(2) chapters but no designed pages → 'No designed pages yet' panel
with + Add page / + Add 10 pages / Go to Chapters buttons
(3) at least one designed page → render the grid normally
Phase J1 polish — pure UI; data model unchanged.

First step on the phase-j-linked-content branch. Splits the book
view's pages-and-chapters mash-up into three tabs (Pages / Chapters
/ Cover) without yet touching the data model or the pagination
engine. Foundation for J2..J6.
What changed:
- New 'Chapters' tab between Pages and Cover. Lists every reflow
entry in book.pages as a row with title, source (naddr or local
draft), size, pin / live / private pills, and per-row Edit / Pin /
Delete actions.
- '+ Add chapter' button moved off the Pages overview's toolbar and
onto the new Chapters tab. Pages toolbar now reads cleanly:
Add page / Add 10 pages / Import page / Read / Export PDF.
- Pages overview hides reflow-entry tiles via a CSS rule
(display:none on .bookPageTile.reflowSegment). Data still lives
in book.pages — drag-reorder indices unchanged, pagination engine
unchanged, PDF export unchanged. J2+ migrates the data out.
- Count readout updated from '0 pages · 0 reflow' to
'N pages · M chapters' (uses 'design' count + 'reflow' count).
- defaultBookState + ensureBookState now scaffold empty links[] and
threads[] arrays so the rest of the codebase can assume they
exist. No code reads them yet.
- setBookSubView extended to handle three views, sets active class
+ display + repaints the active list. renderBookChaptersList
hooked into the main render() loop only when its tab is visible.
Everything that worked before still works — chapter editor, publish
flow, PDF export, Reader Mode, all untouched. The visible change is
the new tab + the cleaner Pages overview.

Drafts the next architectural arc for the Book Designer around two
ideas:
- Events are linked files. Generalizes the pin-vs-live toggle
shipped for chapters to every external reference. A new
book.links[] collection becomes the project's 'Links panel'
(chapters, masters, pages, illustration sets, future asset kinds).
- Threaded text frames (InDesign-style). First-class text-frame
layers on designed pages, threaded port-to-port; a thread
declares a content source (a linked chapter event) and the
pagination engine pours text through the frame chain.
The current 'reflow entries in book.pages' model collapses into
links[] + threads[] + auto-generated designed pages — a one-time
migration on load. Pagination engine, PDF export, Reader Mode,
Linked Designs resolver, and NIP-23 chapter events all survive.
Phasing J1..J6 captured in the spec + TODO. No code yet — this is
just the design doc and arc placement.

The earlier cover-preview commit assumed layers were stored in
panel-local coordinates (0..trimW relative to their panel's trim
corner). They're not. Cover layers are appended directly to
#layerOverlay (renderLayers, ~line 22344: 'el.style.left = inches(layer.x)'),
which lives inside #sheet, so layer.x is sheet-absolute: a back
layer's x already starts at >= bleed, a front layer's x already
starts at >= bleed + trimW + spineW (targetBounds() seeds them
there at creation time). Adding backX / spineX / frontX in the
preview shifted every layer twice — front cover content slid off
the right edge of the canvas, spine content drifted onto front,
back content drifted onto spine.
Fix: just remap target to 'canvas' and pass x / y through. The
panel-offset variables are kept (renamed in scope) only for the
overlay's fold-line and label positioning, which IS in absolute
spread coordinates.
The 'spec backfill' from the prior commit still stands — defensive
against undefined coverHasBack / coverHasSpine on legacy state —
but the visible misalignment in the preview vs. the editor was this
coordinate-system mismatch.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
ensureBookState() now fills in any defaultBookSpec() fields missing
from state.book.spec. Older saved books that pre-date the
coverHasBack / coverHasSpine flags would otherwise restore with those
fields undefined, and the eleven '!!s.coverHasBack' / '!!s.coverHasSpine'
truthiness checks scattered across the cover-preview filter, sheet
sizing, renderDimensions, the cover edit slot layout, and the PDF
export pipeline would all read those as 'false' — silently filtering
back-cover and spine layers out of the spread.
User symptom: a cover with text + linked designs + a background shape
that spans the spread would render only the front panel's content,
because the back / spine layers were being dropped by the filter.
The spread width also collapsed to front + bleed, throwing off the
bleed visualization.
renderBookCoverPreview() now calls ensureBookState() before reading
the spec so the backfill runs even if no prior code path touched the
book this render cycle.

Two new import paths for book covers:
- Load cover from Nostr: paste an naddr / nevent pointing at a
casewrap-page cover-spread event. Pulls layers + spec hints (trim,
bleed, hasBack, hasSpine) + the publish ref so the existing
Re-publish cover flow keeps replacing in place.
- Load cover from JSON: file picker that accepts the format
bookCoverFileExportPayload() emits. Applies layers + spec hints;
clears book.cover.ref because the file isn't yet published.
Both ask before overwriting an existing cover and update the live
preview immediately.
The 'Replace cover from Nostr…' button was already in the HTML but
hard-disabled with a 'Phase D1 stub' note — now wired and re-labelled
'📥 Load cover from Nostr…'.
Also fixes a name collision from the prior JSON-export commit:
bookCoverPayload() was defined twice (Nostr publisher at line 11938,
file exporter that I added at line 26056). JS function hoisting let
the later one win, silently breaking publishBookCoverToNostr's
'page.layers' lookup. Renamed the file exporter to
bookCoverFileExportPayload() so both coexist.

Two fixes wrapped together because they're both about the user
not seeing a meaningful preview in book mode.
1. renderBookCoverPreview() now paints the actual back / spine /
front layers into a single composite canvas the size of the full
wrap-around spread, using the same renderCustomArtPreviewDOM
helper the Pages-overview tiles use. Each layer's target is
remapped to 'canvas' and offset by its panel's position within the
spread (back: x=bleed, spine: x=bleed+trimW, front: x=bleed+
trimW+spineW). On top: a dashed-red trim guide, dashed fold-line
dividers, subtle 'Back / Spine / Front' panel labels, and an
empty-state hint when no cover artwork exists yet. The geometric
panel-mock fallback is gone — the .bookCoverPanel CSS still ships
but is now dead.
2. renderDimensions() no longer falls through to the DVD-cover
else-branch in book mode. The 'Trim: 10.8 × 7.25 in / PDF page:
8.50 × 11.00 in (portrait)' strings that showed for books were
the DVD totalTrimW + state.trimH leaking through. A dedicated
book branch now reads from state.book.spec and shows
'Trim: 6 × 9 in / Spread: ... (with bleed)' when editing the
cover, 'Page: ... (with bleed)' otherwise.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
- The bookPageEditBar CSS only matched .editing-book-page, so the bar
(Back / Publish / Proof / Cover JSON) was completely hidden while
editing the cover. Added .editing-book-cover to the selector so the
bar shows in both modes.
- Back button label is now '✓ Done — back to Cover view' with a tooltip
that says changes are autosaved. The old 'Back to Cover view' label
hid the fact that work persists automatically.
- mediaCategories: added 'Book', 'Meme', 'Other'.

Two new payload builders:
- bookPayload() — captures spec, pages, masters, cover metadata,
every layer that targets a book surface. Hooked into downloadProject
so Save Project (JSON) in book mode now writes a real, round-
trippable book file instead of falling through to coverTemplatePayload
(which silently wrote a malformed DVD-cover JSON for books).
- bookCoverPayload() — cover-only payload with the three cover panels
+ the spec fields the cover needs to lay out correctly (trim, bleed,
safe, spine width snapshotted at export so the file stays portable
between books with different page counts). Surfaced via a new
'💾 Cover JSON' button in the page-edit bar that only shows in
cover-edit mode.

Adds 'overscroll-behavior-x: none' on html / body so the browser
treats horizontal trackpad swipes as no-ops instead of back / forward
navigation. Vertical scroll is unaffected. Prevents the classic
'I lost my work because I scrolled the canvas' design-tool gotcha.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
Two bugs prevented the book cover editor from rendering anything
visible:
1. body.template-book had an unconditional 'display:none !important'
on .coverOnly (and on .bleedFill, .trimArea, .foldLine, .spineText),
so when editing-book-cover was set the slot boxes, fold lines, crop
marks, and trim guides stayed hidden. The hide rule now uses
:not(.editing-book-cover) for the cover scaffolding while still
unconditionally hiding the disc/jewel scaffolding (which never
belongs on a book cover).
2. The .slot positions are driven by --panel-w, --spine-w, --trim-h,
--bleed, --safe CSS custom properties. renderDimensions() was
writing DVD-cover state.* values into those for every render,
including in book cover mode — so even if the slots were visible
they would have been sized for the last DVD preset, not the book
spec. renderDimensions now writes book-spec values into the CSS
vars whenever state.book.editingCover is true, so the back / spine
/ front panels lay out at the book's trim with the spine derived
from page count × paper thickness.
For the asymmetric cases (coverHasBack=false or coverHasSpine=false),
a new applyBookCoverSlotLayout() helper writes inline left / width
overrides for the slot, trim, fold line, and crop-mark elements so
they sit in the right places. clearBookCoverSlotLayout() drops those
overrides whenever we leave cover edit mode so the CSS defaults take
back over. New body classes no-cover-back / no-cover-spine hide the
slot box for the missing panel.
Slot placeholders ('Enter back image URL' etc.) are hidden in book
cover edit mode — those belong to the DVD URL flow, not the book
cover layer system.

Surfaces that Book Designer is still under construction in two places:
- An amber 'Beta' pill on the Book layout-picker tab so users see it
before they switch modes
- A full-width amber notice at the top of the Book sidebar fieldset
that's always visible whenever the user is working in Book mode,
with a short explanation of what works and what to expect

Each docs page now has a header button that copies the raw markdown
source to the clipboard. Useful for pasting the docs into the Book
Designer chapter editor as test content.
- _docsCache now stores { html, md } so the raw source survives the
marked.parse() pass without a re-fetch on copy
- _docsActiveMd tracks the currently displayed page's source
- Button shows a brief "✓ Copied" confirmation and routes through
toastSuccess / toastError for status

67 commits delivering the Book Designer arc (phases A-I) plus the
in-app 'Read the docs' markdown viewer (30 pages across 5 groups)
and ~48 contextual ⓘ help icons knitted into tabs, layouts, panels,
tool sections, the pixel-art UI, welcome / community / tip modals.
Layout-tab buttons (mode-cover / mode-disc / etc) and app-mode tabs
(modeTabTemplate / modeTabDesigner) have direct click listeners that
fire during the bubble phase. The previous bubble-phase docs
delegation ran AFTER those handlers — so clicking the ⓘ inside a
layout tab would swap modes *and* open the docs.
Switching the docs handler to capture phase intercepts the click
before it reaches the wrapping button's bubble listener, and
stopPropagation prevents bubble delivery entirely. Now the ⓘ
opens docs without changing modes.
Verified with a slug-integrity sweep: every data-help attribute in
the UI resolves to a real _DOCS_TOPICS entry (no 404s).

Three more surfaces where docs help is high-value at the moment a
user is making a decision:
- Welcome modal h2 — opens the Overview docs page so first-run
users can orient themselves before picking a starting layout.
- Browse Community modal h2 — opens the Publishing overview
(public/private/premium comparison + tipping vs unlocking).
- Browse Community Premium tab — opens the dedicated
Premium-publishing page so users browsing locked designs can
read about how unlocking works before clicking ⚡.
- Tip modal h2 — opens the Zaps page; restructured the title
area as a flex row so the icon survives the dynamic
textContent updates that swap "Send a tip" vs other labels.
Coverage is now 48 ⓘ icons across the UI.

Adds an ⓘ at the start of the pixel editor's tool bar (left of the
pencil/eraser/fill tool group) that opens the Pixel art docs page.
Pixel mode runs through its own bespoke toolbar (not the standard
left-sidebar fieldset flow), so the editor bar is the right home
for the icon.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
Each individual layout button now carries its own ⓘ so authors get
straight-to-the-page help even before picking a mode. Same delegated
click handler from the previous slice — the layout-tab's mode-switch
click and the icon's docs-open click coexist because the docs handler
stopPropagation's the event before the tab handler sees it.
Layout-picker buttons (8):
- Template tab: Case cover, Disc labels, Slide deck, Book.
- Designer tab: Custom art, Slide, Pixel art, Disc design.
Book sub-surfaces (4):
- Pages / Cover toggle bar — opens the Book page.
- Page editor top bar (book-page + book-master editing) — opens the
Book page.
- Chapter editor toolbar — opens the Book page.
- Reader Mode header — opens the Book page.
CSS:
- .layoutTab .docsHelpIcon — smaller (.76rem) + reduced opacity by
default; active state inverts colour to white-on-accent so the
icon stays readable on a selected tab.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
Every major surface now carries a small ⓘ glyph that opens the in-
app docs modal directly to that surface's page. Single delegated
click handler on document.body (data-help attribute → openDocsModal
slug); zero per-icon wiring.
Placement (30+ icons):
- App-mode tabs — Template → template; Designer → designer.
- Sidebar legends (18) — Layout/Template/Canvas/Slides/Book/Deck
theme/Artwork/Disc Layout/Jewel Inserts/Layers/Project metadata/
Credits/Display options/Print & Save/Save & Export plus the
Designer-tab equivalents — each linking to its matching page.
- Tool-options pane headings (6) — Pen tool, Direct Selection,
Path actions, Pencil tool, Shape tool, Text tool — each opens
its dedicated tool page.
- Modal titles (4) — Document settings, Export PDF, Master pages,
Ready-to-publish — the publish-confirm h2 was restructured to a
flex row so the icon doesn't get wiped by the JS that swaps the
textContent.
- Settings → ⚡ Lightning wallet → opens the NWC setup page.
CSS:
- .docsHelpIcon — 16×16, muted color, inline-flex so it nests
cleanly next to headings/labels. Hover brightens + scales 1.1.
- App-tab variant tones the colour down further (rgba on white +
active states) so the icon doesn't compete with the tab label.
Behaviour:
- Cmd/Ctrl/Shift clicks pass through (let the browser handle if
the icon is ever wrapped in a link).
- Each icon has role=button + aria-label + title for accessibility.

The docs audit (commit ef03f73) caught several universal design-tool
conventions that aren't wired in the vector toolset — most are
single-branch additions to existing drag handlers. Capture them in
TODO.md under "Design-tool follow-ups" as a discrete cluster so we
remember they exist.
The 14 items:
- Select tool: Shift-constrain-axis on drag, Alt-drag duplicate,
Shift-aspect-lock on corner scale, Shift-rotation 15° snap.
- Global: Cmd+A select-all, Spacebar temp-pan, Cmd+0 fit-zoom,
Cmd+=/- zoom step.
- Shape tool: Shift-constrain to perfect primitive, Alt-from-center
draw.
- Text tool: drag-to-size.
- Pencil tool: smoothing slider, Alt-drag append, auto-close near
start.
Each entry notes rough scope so we can pick them off in any order.
None are blockers; the docs audit just reminded us they're missing.

Adds a "Publishing & payments" group covering the three tiers, the
Lightning plumbing, and how to wire a wallet up:
- publishing.md — Overview of Public / Private / Premium
with a comparison table; how tipping vs
unlocking differs; replaceability +
republish-vs-fork.
- publishing-public.md — Default tier. Event shape, tag layout,
discoverability, edit-vs-fork.
- publishing-private.md — End-to-end encrypted to self via NIP-44
/ NIP-04. AES-256-GCM pipeline, what stays
visible (pubkey, kind, d-tag), multi-
device decrypt via "Mine" tab, caveats
(no multi-recipient envelopes in v1).
- publishing-premium.md — Zap-gated soft-gate publishing. Soft-gate
key derivation, watermarked preview,
zap-split tags (creator + platform),
buyer unlock flow, My Purchases vault,
honest framing about soft-gate limits.
- zaps.md — NIP-57 lightning payments. Tipping vs
unlocking. How to receive zaps (set
lud16 on profile). Fallback flow without
NWC (BOLT11 + QR + external wallet).
- nwc.md — Nostr Wallet Connect (NIP-47) setup.
CoinOS quickstart, supported wallets,
multi-device sync via NIP-44 encrypted
event, test-connection button, security
model (treat URI like a password + set a
budget).
Plus a "Why JPEG sometimes routes through PDF" section added to
panel-print-save.md, explaining the three fallback cases (CORS-
blocked images, tainted canvas, unsupported mode) and the auto-
switch to the print → PDF path that the browser's print engine
can handle.

Swept the help pages against the actual code paths and removed /
corrected claims that didn't ship.
vector-tools.md
- Removed: spacebar temp-pan, Alt duplicate-as-you-drag, generic
Shift-constrain.
- Added: verified shortcuts (Cmd+Z/Y/D/C/X/V/G, Cmd+]/[ with
Shift modifier, Cmd+J / Cmd+Alt+J in Pen edit mode,
Delete/Backspace for layers + anchors).
tool-select.md
- Removed Cmd+A (not wired), Alt-drag-duplicate (not wired),
Shift-constrain-axis drag (not wired), Cmd-click stack-walk
(not wired). Kept the verified marquee + multi-select.
tool-direct-select.md
- Re-wrote anchor / handle interactions to match the actual hit-
test branches (Alt-click anchor toggles kind in one click; Alt-
drag a handle breaks symmetry; Alt-click segment inserts an
anchor; plain drag of a segment bows it). Removed the "click an
endpoint to continue drawing" claim — that's a Pen-only flow.
tool-hand.md
- Removed every fictional zoom shortcut (Cmd+wheel, Cmd+0,
Cmd+= / Cmd+-). Documented the real zoom controls (−/+/Fit
buttons + dropdown in the canvas toolbar). Spacebar reposition
scoped correctly to the Pen tool only.
tool-pen.md
- Clarified that the Pen options pane has its own Fill / Stroke
inputs (separate from any "Stroke panel" that doesn't actually
exist).
tool-pencil.md
- Removed every claim that wasn't true: smoothing slider, Alt-drag
append, auto-close. Pencil writes a plain polyline (M…L L L…),
one layer per stroke. Tool options pane has only colour + width.
tool-shape.md
- Filled in the missing primitives (rounded-rect / circle /
triangle — total 8, not 5). Removed Shift / Alt drag modifiers
that aren't checked in startShapeDrag / commitShapeFromDrag.
Added the small-drag → default-size fallback that the code does
do.
tool-text.md
- Replaced the "drag a rectangle to size" claim with the actual
click-to-place behaviour (placeTextWithTool drops a fixed-size
box at the cursor + auto-flips to Select with the box focused).
Softened the Cmd+B/I/U claims to "browser native rich-text
shortcuts" since they're not wired in the app code.
tool-eyedropper.md
- Replaced the fictional "inline ⊙ buttons next to colour fields"
with the real OS-colour-picker eyedropper that Chrome's native
<input type="color"> shows.
panel-layers.md
- Removed Cmd+A select-all (not wired). Added Shift modifier to
Cmd+]/[ for bring-to-front / send-to-back. Clarified that
position units are inches in print modes, pixels in Custom Art
/ Slide / Deck (matches the unit toggle behaviour).

Adds a "Sidebar panels" group to the in-app docs:
- panels.md — overview + a table of every sidebar panel
with where it lives + a one-liner
- panel-metadata.md — Project Metadata fields (title, category,
IMDb/UPC/TVDB/MBID/custom-tag/language)
+ how they feed publish + designer-mode
equivalent
- panel-layers.md — Layers panel — per-mode surface scoping
(Cover/Disc/Jewel/Custom Art/Slide/Deck/
Pixel/Book), per-row controls, reorder +
group + multi-select, layer-options
field list
- panel-export.md — Export options panel — show/print toggles
for guides/bleed/safe/crops/fold, mode-
specific hides
- panel-print-save.md — Save / Open project JSON + Print/Save-as-
PDF print-dialog tips + Export JPEG/PNG +
mode-specific gotchas
- panel-credits.md — Credits panel — Linked Designs contributor
surfacing, tip button, publish-time tag
emission, private-publish behaviour
- panel-tool-options.md — Right-side floating Tool Options pane —
how it switches between tool options and
layer options, cross-links to per-tool docs
Registered as a new "Sidebar panels" group ordered after Vector
tools in the docs sidebar.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
Adds a new "Vector tools" group to the in-app docs sidebar with one
page per toolbar tool + one page per supporting panel:
Toolbar tools (8):
- tool-select.md — Select (V): move/scale/rotate whole layers,
multi-select, marquee, dive-into-path
- tool-direct-select.md — Direct Selection (A): per-anchor edits,
handle break, segment-direct-edit
- tool-hand.md — Hand (H): pan + temp-pan via Spacebar,
plus zoom controls (which work from any
tool)
- tool-pen.md — Pen (P): full Illustrator parity —
Bézier draw, mid-draw spacebar reposition,
Alt handle-break, auto-add/delete anchors,
Cmd+J join, Cmd+Alt+J average
- tool-pencil.md — Pencil (B): freehand → smoothed Bézier
- tool-shape.md — Shape (S): rect/ellipse/polygon/star/line
primitives + Shift/Alt modifiers
- tool-text.md — Text (T): rich-text layer + Type panel
+ token notes
- tool-eyedropper.md — Eyedropper (I): window.EyeDropper sample +
inline ⊙ buttons + browser-support notes
Supporting panels (3):
- pathfinder.md — Unite/Subtract/Intersect/Exclude via the
vendored polygon-clipping
- align-distribute.md — six align ops + four distribute ops, with
behaviour around locked layers
- free-transform.md — multi-layer scale + rotate handles on
the selection bbox
Plus an overview page (vector-tools.md) with a keyed table of every
shortcut, a description of how the toolbar interacts with the Layers
panel, and the canvas-level keyboard shortcuts (Shift/Alt/arrow
nudges/Cmd+D/etc).
All linked into _DOCS_TOPICS as a new "Vector tools" group, ordered
after the existing Template-mode layouts section.

Adds a 📖 Docs link to the sidebar footer (next to GitHub + artstr.org)
that opens a Read-the-Docs-style two-pane modal: topic sidebar on the
left, rendered markdown on the right.
Content (src/help/*.md, 11 files):
- index.md — overview + nav
- template.md — Template tab explainer
- designer.md — Designer tab explainer
- cover.md — Case cover wrap
- disc.md — Disc-label sheet
- jewel.md — Jewel-case insert
- customart.md — Custom art
- slide.md — Slide
- deck.md — Slide deck
- pixelart.md — Pixel art
- book.md — Book Designer (links out to the deeper
BOOK_DESIGNER_TUTORIAL.md + spec on GitHub)
Implementation:
- _DOCS_TOPICS registry maps slug → { title, group, file }. Sidebar
groups headings under "Start here", "App tabs", "Template-mode
layouts".
- loadDocsTopic(slug) fetches `help/<slug>.md` (force-cache), renders
via the already-vendored marked, caches the rendered HTML for
session-instant re-visits, and updates the URL hash via
history.replaceState so deep links work.
- #/help/<slug> hash route auto-opens the modal at that topic on
page load + on hashchange.
- Esc closes; backdrop click closes; internal `#/help/foo` links in
page content load via the dispatcher (no page bounce); external
http(s) links get target="_blank" + noopener.
Styling:
- Inherits the rest of the modal aesthetic (var(--line),
var(--accent), system font for chrome, Georgia serif for body
text). Dark-mode-aware backdrops on code / blockquote / table
blocks.
- Two-pane layout collapses to a narrower sidebar on <720px viewports.
Files live in src/help/ (not docs/) because Vercel's outputDirectory
is "src" — the production site only serves files under src/. The
canonical deeper docs (BOOK_DESIGNER_TUTORIAL, FEATURE specs) stay
in docs/ and are linked-out from the in-app pages.
